Preparing for Sharepoint 2010: Importing your old sharepoint 2007 sites

2009-07-17T10:22:00.010+02:00

A look info the future, don't be afraid, migrating your old 2007 sharepoint sites can be imported into the new Sharepoint 2010..... but what will happen when importing 2007 sharepoint export files (.cmp* files) into the new 2010?

When you upgrade Sharepoint 2007 to 2010, by default the layout will stay like it is in 2007, but this setting can be changed:
Go to Site Actions > Preview New Visuals, choose one of the 3 new options:

Keep the previous Sharepoint user experience (default)
Preview the new Sharepoint 2010 user experience, but let me return to the previous user experience
=> allows you to flip between the old and new experience and prevents you to do something that isn't compatible with the old version
Use the Sharepoint 2010 user experience and don't ask me again
=> you can do things that are incompatible with older versions

Your servers (development, production, everything!) need to be 64bit!

Sharepoint 2010 News

2009-07-10T17:34:00.005+02:00

Todd Haugen (Group Program Manager SharePoint Designer at Microsoft) added some info about SP2010 "Developer's experience" on the LinkedIn group Sharepoint 2010:

Improvements both at the API level and inside VS2010
Documentation is much improved
Supporting LINQ so that developers will not have to access lists using the archane SharePoint API and rather use much more standard OO notation that is supported by intellisense.
We also improve support for Silverlight.
Plans with Azure are not clear

Where I can download the Sharepoint 2010 Beta?

Microsoft SharePoint 2010 beta will be "invitation-only" :-(
Maybe there will be a public beta "later in 2009" ...

How do I prepare my environments for Sharepoint 2010 ?

Deploy Service Pack 2 and take a good look at the SharePoint 2010 Upgrade Checker that’s shipped as part of the update. The Upgrade Checker will scan your SharePoint Server 2007 deployment for many issues that could affect a future upgrade to SharePoint 2010.

Sharepoint 2010 Requirements:

SharePoint Server 2010 will be 64-bit only. (We should also create 64 bit virtual environments?!)
SharePoint Server 2010 will require 64-bit Windows Server 2008 or 64-bit Windows Server 2008 R2.
SharePoint Server 2010 will require 64-bit SQL Server 2008 or 64-bit SQL Server 2005.

Redirecting after using InfoPath Form (web-enabled) in Sharepoint 2007

2007-10-02T08:35:00.000+02:00

Use the Source query string: so the page will know where to navigate to after the form is closed or submitted (Watch Out: The URL must be in the same site collection or an error will be returned.)
Add the OnClose event to the XmlFormView, add code to redirect after closing:
Response.Redirect(http://www.dolmen.be);
In the Infopath Form, you must add the Action: "Close this form: No Prompt" in the rules of the InfoPath Button, otherwise the OnClose event won't fire.

Query DataConnection in Infopath Web-enabled Form when selecting value of dropdownlost (with Managed Code)

2007-08-19T20:39:00.000+02:00

You don't always need to load your dataconnection before the form is loaded (performance reasons), sometimes you want to load a different dataconnection when a certain value is selected. I use the example of a dropdownlist, and every value of the dropdownlist will load an other dataconnection into another dropdownlist.

Add the 2 dropdownlists, the second dropdownlist must have a connection with a datasource (I use an embedded Xml file dc.xml). When creating this dataconnection, please deselect the setting "Automatically retrieve dat when form is opened".

What you will need after you created the controls in infopath, open VSTA (alt+shift+F12). Add following code fragment into the InternalStartup method:


this.EventManager.XmlEvents["/my:myFields/my:Type"].Changed += new XmlChangedEventHandler(TypeChanged);

You also need to add the TypeChanged methods:


void TypeChanged(object sender,XmlEventArgs e)
{
  string type = e.NewValue; //the selected value of the type dropdownlist
  
  //I just added one dataconnection called dc (value when you select POST)
  //You need to put here code (switch) for all the values in the type ddl    
  DataSource ds = this.DataSources[type];
  DataConnection dc = ds.QueryConnection;

  dc.Execute();
}

When you use the Execute method of a dataconnection, you must change following setting (it is like the ASP.NET AutoPostBack setting), otherwise your dataconnection will not be loaded!! (when you just changed a value of another field, you don't need to change this setting).

Change the standard option (postback settings): "Only when necessary for correct rendering of the form (recommended)" to "Always"

Remarks:
When you use Mananged Code in web-enabled form, uou must publish it as an administrator approved template (check out blogpost http://spsfactory.blogspot.com/2007/01/walkthrough-publishing-administrator.html )

Adding AppSettings to a Sharepoint Web Application Web.Config

  ("add[@key='{0}']", name), "/configuration/appSettings");
          
  modification.Type =
  SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode;
  modification.Value =  string.Format(CultureInfo.InvariantCulture,string.Format
  ("",name,value) );
           
  if (allModifications.Contains(modification))
  {
    allModifications.Remove(modification);

CAML and strange characters like '&'

2007-07-05T16:34:00.000+02:00

Some day, my Caml Query failed with this exception:
"The property Query contains an invalid value."

The CAML XML:


<pre>
<Where>
  <Eq>
    <FieldRef Name='Summary'/><Value Type='Text'>jeroen & doreen></Value>
  </Eq>
</Where>

I noticed the & and found out that the & character was the problem. Changing it into the encoded & gave the same problem... Thx to JOPX's connections in the Sharepoint world (of art;-) ) someone gave me a tip: try it with CDATA.....

So I check that out........ and it worked!!

So you need to put a CDATA tag around the text that can contain strange characters:

My new correct working CAML XML look like this:


<Where>
  <Eq>
    <FieldRef Name='Summary'/>
      <Value Type='Text'>  <![CDATA[jeroen & doreen]]> </Value>
  </Eq>
</Where>

Some more info about CDATA:
Source: http://www.w3schools.com/
A CDATA section starts with "<![CDATA[" and ends with
"]]>":

<script>
<![CDATA[
function matchwo(a,b)
{
if (a < b && a < 0) then
   {
   return 1
   }
else
   {
   return 0
   }
}
]]>
</script>

In the example above, everything inside the CDATA section is ignored by
the parser.

Notes on CDATA sections:
A CDATA section cannot contain the string "]]>", therefore, nested CDATA sections are not allowed. Also make sure there are no spaces or line breaks inside the "]]>" string.

Creating Managed Properties for use in SharePoint Server Enterprise Custom Search through Code

2007-06-06T21:06:00.000+02:00

Use the following Code to add Managed Properties in Code, the Managed Properties are created from crawled properties (like an infopath published form)


//Get search Schema
ServerContext serverContext = ServerContext.GetContext("SharedServices1");
SearchContext searchContext = SearchContext.GetContext(serverContext);  
Schema schema = new Schema(searchContext);

//Get the list of properties (here from a published infoPath Form), you want to use in search
StringCollection infoPathFormProperties = GetData.GetAllInfoPathPublishedFields();
// Create new ManagedProperties
foreach (string infoPathFormProperty in infoPathFormProperties)
{ 
        string managedPropertyName = infoPathFormProperty;
        string infoPathFormPropertyPublished = string.Format("ows_{0}", infoPathFormProperty); //infopath published fields will be added as ows_[NAME]

        // If you create a prop that already exists, you will get an SqlException (duplicate key),so you need this check
        if (!schema.AllManagedProperties.Contains(managedPropertyName))
        {                
             ManagedProperty newManagedProperty = schema.AllManagedProperties.Create(managedPropertyName, ManagedDataType.Text);

             // Get the (crawled) property you want to map in the ManagedProperty
             CrawledProperty cprop = null;
             foreach (CrawledProperty prop in schema.QueryCrawledProperties(infoPathFormPropertyPublished, 1000, Guid.NewGuid(), string.Empty, true))
             {
                  //schema.GetCrawledProperty(Guid.NewGuid(), infoPathFormPropertyPublished, 0); //can't use this, you need also need the Guid and variantType, and you only know the name
                  //QueryCrawledProperties will be filtered on CONTAINING infoPathFormPropertyPublished value, so extra check if the Name is equal!
                  if (prop.Name == infoPathFormPropertyPublished)
                  { 
                       cprop = prop;
                       break;
                  }
              }

              if (cprop != null)
              {
                   // Map the crawled prop to the Managed Prop
                   MappingCollection mappings = new MappingCollection();
                   mappings.Add(new Mapping(cprop.Propset, cprop.Name, cprop.VariantType, newManagedProperty.PID));

                   newManagedProperty.SetMappings(mappings);

                   // Set Some other properties
                   newManagedProperty.FullTextQueriable = true;
                   newManagedProperty.EnabledForScoping = true;
                   newManagedProperty.Update();
               }
               else 
               {
                   MessageBox.Show(string.Format("Published Infopath field {0} not found",infoPathFormPropertyPublished));    
               }

               }
        else
        {
             MessageBox.Show(infoPathFormProperty  +" already exists");
        }

SPSecurity.RunWithElevatedPrivileges to update SPRoleAssignment of an SPListItem

2007-05-15T20:31:00.000+02:00

When you write custom code in Sharepoint webparts, your code will run with your credentials.
Not everybody has Full Control, so when a user has only read rights, the code will throw an access denied error when the code needs access to objects that are not in the scope of the user credentials.... (example: add the username in the ReadBy properties of an item).

What you need is impersonation, run your code with the help of a user who has just enough rights to run it. Sharepoint has a built-in function to accomplish this: SPSecurity.RunWithElevatedPrivileges, it runs with the System Account User.

Some things you should know when using SPSecurity.RunWithElevatedPrivileges:

in the delegate function, you must build a new SPSite/SPWeb object (like SPSite siteColl = new SPSite(App.SITE_COLLECTION_URL)) and you can't use the SPContext.Current.Web, because the SPContext runs with the current context (with current user).
Also set the AllowUnsafeUpdates property of the site/web where you will be updating/accessing stuff to true, to be sure you don't get an error like "The security validation for this page is invalid" (see more below). If you don't do it, you code will work, but when returning from the delegate function, the error will arise..

Code sample:

I run the "Elevated code" when the button btn is clicked in a webpart:

void btn_Click(object sender, EventArgs e)
{
   {
     SPSecurity.RunWithElevatedPrivileges(TestSec);
   }
   catch (Exception ex)
   {
     throw ex;
   }
}

public void TestSec()
  {
    SPSite siteColl = new SPSite(App.SITE_COLLECTION_URL);
    SPWeb site = siteColl.AllWebs[App.WEB_NAME];
    SPList list = site.Lists["Test"];

    SPListItem testItem = list.GetItemById(1);
    site.AllowUnsafeUpdates = true;
    SPRoleDefinition roleDefinitionContributor = site.RoleDefinitions.GetByType(SPRoleType.Contributor);
    SPRoleAssignment roleAssignment = new SPRoleAssignment("DOMAIN\\USERNAME", "", "", "");
    roleAssignment.RoleDefinitionBindings.Add(roleDefinitionContributor);
    ////Check for permission inheritance, and break if necessary
    if (!testItem.HasUniqueRoleAssignments)
    {
      testItem.BreakRoleInheritance(false); //pass true to copy role assignments from parent, false to start from scratch
    }
  testItem.RoleAssignments.Add(roleAssignment);
  testItem.Update();
  site.AllowUnsafeUpdates = false;
  siteColl.Close();
  site.Close();

}

Error when not setting AllowUnsafeUpdates = true:

Working with the Replicator in Sharepoint Workflows, some serialize issues & tricks

2007-03-02T16:20:00.000+01:00

Before reading this post:

Keep in mind: A replicator is just a "workflow foreach".

When initializing a replicator you need to pass initiation data (like the foreach collection data). So if you want to pass a Contact for each replicated activity, you will set the initiationChildData (must implement IList) with Contact objects:
adding contacts like this: replicatorInitialChildData.Add(contact);

Sometimes you want the add your own classes to the List. You would except that this wouldn't be difficult, in fact it isn't:

Create the initiation data list with objects of your custom class:
IList replicatorInitialChildData = new List();
/ fill the list with the ApproverFlow objects
replicatorInitialChildData.Add(appFlowObj1);
replicatorInitialChildData.Add(appFlowObj2);

The code will compile, the workflow will succeed sometimes (when the replicator is used in Parallel execution), sometimes not (when the replicator is used in Sequence execution), after a while you will notice this kind of errors:

SPPersistedObjects or SPAutoserializingObjects; or collections of any of the above. Consider redesigning your objects to store values in
one of these supported formats, or contact your software vendor for support.

You will notice the deserialize stuff.... If you think further, ..... whole the workflow idea is that every instance can be serialized or deserialized, because a workflow can wait for some other stuff, so objects will be saved somewhere (not in memory) when workflow is waiting.

When the replicator starts in parallel execution, no (de)serialize will occur because the workflow doens't need to serialize the objects, the replicator executes everything at once.
But when the replicator executes in sequence, it does need (de)serializing because the workflow will pause before executing the next step (so state is saved:(de)serializing occurs).

So when you want to add your own classes, keep in mind that your own class must be serializable.

Which types are serializable?
The platform can deserialize primitive types such as strings, integers, and GUIDs; other SPPersistedObjects or SPAutoserializingObjects; or collections of any of the above.

In one of the next blog posts, I will explain how to add/change data when the replicator is already running ...

Handle the InfoPath Forms Services by yourself (in a Custom WebPart to view a web-enabled Infopath 2007 Form)

2007-01-15T08:34:00.000+01:00

To understand this post well, please go through this post first:
- Hosting the InfoPath 2007 Form Editing Environment in a Custom Web Form

Sometimes you don't want to popup an error by InfoPath Forms Services (it will log this also in the EventLog), see image below. You want to catch the error in code and do some custom logging (or other stuff)

I will use the example when a dataconnection (webservices) in the form gives a time-out.

Preceding:
First keep in mind that we will bind the dataconnection-webservice to its control in code, so you have to deselect - Automatically retrieve data when form is opened (when adding a data-connection in InfoPath). Also don't forget to link the control with the dataconnection in infopath designer

What we gonna do in code:
- Add a handler that will get you into the Initialize methods of the XmlFormView
- Get the right dataconnection, execute it (so it will get the data and bind to the control)
- Add a "try/catch" block around this code

The code:


void viewform_Initialize(object sender, InitializeEventArgs e)
{
   try
   {
      DataConnection dc = _viewform.XmlForm.DataSources["GetGAL"].QueryConnection;
      dc.Execute();
   }
   catch (System.Net.WebException webEx)
   {
      WarmUpWebService();
      ReloadWebPart();
      //Log, ...
   }
   catch (Exception ex)
   {     
      Logger.Log(ex, ...);
   }
}

Time-outs when using WebEnabled Infopath Form in Sharepoint 2007 WebParts

2007-01-10T21:07:00.000+01:00

When you are using web-enabled infopath forms (that have dataconnections to webservices) in sharepoint 2007, you can get timeouts errors....

Example of an Time-out Exception:
Forms Services Runtime - Data Connections - TYPE: WARNING - EVENT 5566
The following query failed: GetSomething (User: MMMM\bbbbb, Form Name: formname, IP: , Request: http://serverZZZ/xxxx/yyyyy/composer.aspx?menu=3&Type=0, Form ID: urn:schemas-microsoft-com:office:infopath:xxxxxxx:-myXSD-2006-08-07T07-37-16, Type: DataAdapterException, Exception Message: The operation has timed outThe operation has timed out)

How to solve them?

Check if your WebServices time-outs occur when you use the WebService directly (in a webbrowers), If so, you should change the timeout of the WebService in IIS Manager (InetMgr) or use more caching.
If you are loading the Web-enabled InfoPath form into a custom webpart, you have to be sure that the following setting is used in the Form Library Advanced Settings page:
Display as a Web Page (in stead of Open in the client application)

Change the Data Connection Timeouts Settings. Open SharePoint 3.0 Central Administration: Goto Application Management > Configure InfoPath Forms Services
Here you can change the Data Connection Timeouts Settings

Point 2 has fixed my problems...

Problems starting VSTA in Infopath 2007 with Microsoft Office Server Sharepoint 2007 (.NET 3.0) installed !!!FIXED!!!

2007-01-08T09:16:00.000+01:00

To fix the problem described below:

It worked for me when I did this:
uninstall .NET programmability support for .NET Framework version 2.0 and then reinstall it

(go to Kristof his blog for full explanation)

When I want to add custom C# in an Infopath 2007 form, I get this error:

InfoPath cannot start Microsoft Visual Studio Tools for Applications.
To work with Visual Basic or C# code, Microsoft Visual Studio Tools for Applications (VSTA) is required. the Microsoft .NET Framework 2.0 and Microsoft Core XML Services 6.0 must be installed prior to installing VSTA. To install VSTA, open Add or Remove Programs, locate your 2007 Microsoft Office System installation, and then click Change

How should I make this work? Reinstalling some things? I think the .NET 3.0 will cause the problems....

This stuff is installed:

Microsoft .NET Compact Framework 1.0 SP3 Developer
Microsoft .NET Compact Framework 2.0
Microsoft .NET Framework 2.0
Microsoft .NET Framework 3.0
Microsoft Office Enterprise 2007
Microsoft Office Sharepoint Designer 2007
Microsoft Office Sharepoint Server 2007
Microsoft Visual Studio 2005 Professional Edition
Microsoft Visual Studio 2005 Team Explorer
Microsoft Visual Studio 2005 Tools for Office Runtime
Windows Server 2003 Service Pack 1
Regarding Workflow:
Enterprise Content Management Starter Kit for 2007 Office System (beta 2 tr)

When I want to re-installing MSXML 6.0 I get this error:

Installation of MSXML 6.0 Parser failed because a higher version already exists on the machine. To proceed uninstall the higher version and then run MSXML 6.0 Parser Setup again

Kristof De Causemaeker add some more comments:
When you want to create an InfoPath Add-in project via VSTO, it also give errors...
I thinks that VSTO/VSTA in combination with .NET 3.0 and InfoPath 2007 will not work yet..... Maybe a Windows Registry problem?

Using CAML to filter a infopath published boolean field (from a sharepoint list)

2006-11-25T20:22:00.000+01:00

In a infopath form we have a boolean field called Draft, we publish the form to a sharepoint list, and we want to filter that list using Caml queries:
Which value should the BOOLEANVALUE have to succeed the query?
False/True ? Yes/No ? 0/1 ?
What I noticed is, when I published the infopath form the boolean type in intopath will be a Yes/No Type in the sharepoint list.....

So the Caml query will not work with BOOLEANVALUE = False/True Or Yes/No , you have to use 0 or 1...

Implement the CAML query into code:

StringBuilder camlBuilder = new StringBuilder();

string queryText = camlBuilder.ToString();

SPWeb site = SPContext.Current.Web;
SPList list = site.Lists["Mail"];
SPQuery query = new SPQuery();
string queryText =""
query.Query = queryText;

results = list.GetItems(query);
foreach (SPListItem item in results)
{..............}

If you put the query Tag as root tag into the query text, you will receive all items, zo don't put it there, some stupid guy I know very good did that ;-)

SPListItem looses Property data type when publishing Infopath form to a sharepoint list (MOSS 2007 beta2TR)

2006-11-25T19:57:00.000+01:00

When you publish a Infopath Form to a sharepoint list, the Infopath form contains some fields (text and date(time) data types). These fields are copied to a sharepoint list when you publish the form to it.

You should think sharepoint keeps the data types like in the infopath form, but this isn't, I noticed that the date(time) data type is just a string/text field in the sharepoint list!

The strange thing is that when you add a column in the published list manualy (for example a datetime field), it will keep the data type and not change it to a string.

I noticed it when a wanted to perform an update an a field called ApprovalDate (Date Datatype) in a Web Part:


SPSite site = new SPSite("http://......");
SPListItemCollection results = site.Lists["InfopathPublishedList"].Items;
foreach (SPListItem item in results)
{
     item.Properties["ApprovalDate"] = DateTime.Today;//DateTime.Today.ToString();
 item.Update();
}

This code failed when I did this on the datetime field published by infopath:

Error:Specified data type does not match the current data type of the property. at Microsoft.SharePoint.Utilities.SPUtility.UpdateArrayFromHashtable(Object& o, Hashtable ht) at Microsoft.SharePoint.SPListItem.PrepareItemForUpdate(Guid newGuidOnAdd, Boolean bMigration, Boolean& bAdd, Boolean& bPublish, Object&
objAttachmentNames, Object& objAttachmentContents, Int32& parentFolderId) at Microsoft.SharePoint.SPListItem.UpdateInternal(Boolean bSystem, Boolean bPreserveItemVersion, Guid newGuidOnAdd, Boolean bMigration,
Boolean bPublish, Boolean bNoVersion, Boolean bCheckOut, Boolean bCheckin, Boolean suppressAfterEvents) at Microsoft.SharePoint.SPListItem.Update()

This doesn't happen if the ApprovalDate is added by create column in the list.

So watch out, and as you notice in the picture below: It ain't what it look like........

System.Web.UI.WebControls.WebControl doesn't fire all events

2006-11-21T23:19:00.000+01:00

During the development of a ServerControl for a masterpage in a Sharepoint site, I added some eventhandlers in the CreateChildControls(): DayRender, VisibleMonthChanged and SelectionChanged.

After debugging, I noticed that only the DayRender event worked. I googled sites and newsgroups to find a solution, but I didn't find an answer....
After sending this problem to a colleague(thanks to: Sam), he answered this:

If you inherit controls from the WebControl class, you will get problems with events and state. So if you need dynamic controls, let them inherit from the CompositeControl class, this class is special made for controls that contains other controls.

At the CompositeControl MSDN page I found this:
The CompositeControl class is an abstract class that provides naming container and control designer functionality for custom controls that encompass child controls in their entirety or use the functionality (STATE AND EVENT HANDLING?!!?) of other controls.

Below some code of a custom Calendar that inherit from CompositeControl :

public class MailCalendar : System.Web.UI.WebControls.CompositeControl


{
        private System.Web.UI.WebControls.Calendar ctlCalendar;
      
       protected override void Render(HtmlTextWriter writer)
      {
            this.EnsureChildControls();
            this.ctlCalendar.RenderControl(writer);
      }
    
     protected override void CreateChildControls()
    {
           this.Controls.Clear();
           this.ctlCalendar = new System.Web.UI.WebControls.Calendar();
           ctlCalendar.VisibleDate = DateTime.Today; this.ctlCalendar.DayRender _
              += new DayRenderEventHandler(ctlCalendar_DayRender);            
         
           this.ctlCalendar.VisibleMonthChanged _
             += new MonthChangedEventHandler(ctlCalendar_VisibleMonthChanged); 
         
           this.ctlCalendar.SelectionChanged _
             += new EventHandler(ctlCalendar_SelectionChanged); this.Controls.Add(ctlCalendar);
    }

     void ctlCalendar_SelectionChanged(object sender, EventArgs e)
    {
           this.Context.Response.Redirect(.......);
     }

      void ctlCalendar_VisibleMonthChanged(object sender, MonthChangedEventArgs e)   
     {
        ctlCalendar.VisibleDate = e.NewDate;
     }
      
     void ctlCalendar_DayRender(object sender, DayRenderEventArgs e)
    {
           // Set date to bold if its today
            Style boldStyle = new Style();
            boldStyle.Font.Bold = true;

           if (e.Day.Date == DateTime.Today)
           { e.Cell.ApplyStyle(boldStyle); }
     }
}

Bullshit Bingo - How to stay awake in meetings

2006-05-18T15:52:00.000+02:00

From Guy Bursteins blog, seen on JopX blog

Do you keep falling asleep in meetings and seminars? What about those long and boring conference calls? Here's a way to change all of that. 1. Before (or during) your next meeting, seminar, or conference call, prepare yourself by drawing a square. I find that 5" x 5" is a good size. Divide the card into columns - five across and five down. That will give you 25 one-inch blocks. 2. Write one of the following words/phrases in each block:

synergy
strategic fit
core competences
best practice
bottom line
revisit
expeditious
to tell you the truth (or "the truth is")
24/7
out of the loop
benchmark
value-added
proactive
win-win
think outside the box
fast track
result-driven
empower (or empowerment)
knowledge base
at the end of the day
touch base
mindset
client focus(ed)
paradigm
game plan
leverage3.

Check off the appropriate block when you hear one of those words/phrases. 4. When you get five blocks horizontally, vertically, or diagonally, stand up and shout "BULLSHIT!" Testimonials from satisfied "Bullshit Bingo" players: "I had been in the meeting for only five minutes when I won." - Adam, Atlanta "My attention span at meetings has improved dramatically." - David, Florida "What a gas! Meetings will never be the same for me after my first win." - Dan, New York City "The atmosphere was tense in the last process meeting as 14 of us waited for the fifth box." - Ben, Denver "The speaker was stunned as eight of us screamed 'BULLSHIT!' for the third time in two hours." - Paul, Cleveland

Enjoy your meetings!

Convert byte[] to an Image/bitmap: why the System.ArgumentException: Invalid parameter used arises.....

2006-04-28T10:36:00.000+02:00

I need images saved by an old vb6 program and convert them to a new db of a new prog. The old programma saved the images data into a image field of a SQL2000 DB. First I justed copy the image from V1 (db of the old programma) to V2 (the db (also SQL2000) used in the new program).

Problem: the data in the image field is corrupt! When I try to convert that data into a bitmap or jpg it gives me a Invalid parameter Exception when I do this code:

MemoryStream ImageDataStream = new MemoryStream();
// byte[] ImageData, filled with the image field of db
ImageDataStream.Write(ImageData,0,ImageData.Length);
ImageDataStream.Position=0;
Image img = Image.FromStream(ImageDataStream); //Invalid parameter Exception thrown

This is because the byte data of ImageData is corrupt due a Unicode encoding done by the old VB6 programma before/while saving it to db. Below some byte code (hex style) so that you can see the the good data vs the corrupt/wrong data:

A bitmap header starts with BM, so there you see that the is a doubling of the data: from 42 4D to 42 00 4D 00 => convertion to Unicode. You can't simply remove the 00 because unicoding is not just a 00 extend. For example 75 87 95 59 (see above in picture) will be converted to 75 00 21 20 22 20 59 00 and not just 75 00 87 00 95 00 59 00 !!

So what you have to do is convert the data back to the current ANSI code page (Encoding.Default):
ImageData=System.Text.UnicodeEncoding.Convert(Encoding.Unicode,Encoding.Default,ImageData);

So the code below will do the good convertion......
MemoryStream ImageDataStream = new MemoryStream();
ImageDataStream.Write(ImageData,0,ImageData.Length);
ImageDataStream.Position=0;
ImageData=System.Text.UnicodeEncoding.Convert(Encoding.Unicode,Encoding.Default,ImageData);
Image img = Image.FromStream(ImageDataStream);

Not every "Invalid parameter used" exception will be fixed like that, sometimes you need an other Convertion with other Encoder parameters or the image can have a added header (like the 78 long ole-header,..... => the code will be like ImageDataStream.Write(ImageData,78,ImageData.Length-78); )

Good luck!

Messed up bitmap data ? FIXED (SEE ABOVE!)

2006-04-27T08:20:00.000+02:00

On http://www.lierse.be/VB6bitmap.zip is a dat file (from an image field in SQL2000), it is a bitmap file, in an old VB6 programma that image is used and visible. So it is valid data. Problem: no code of vb6 of that prog is available.

My question: What is wrong with the bitmap data? does vb6 add some rubbish to it? I can't load it into image object in C# because a invalid argument exception (because somethings is wrong in the header or ...). I tried every offset (some people say use 78 as offset, because there will be a OLE header), and every offset gives the same error. I get an invalid argument when i do this:
ImageDataStream.Write(ImageData,i,ImageData.Length-i); // ok, tried every value of i
Image img = Image.FromStream(ImageDataStream); // the invalid argument error rises here

I'm trying now to rip the pixeldata and put the pixeldata in a own created bitmapfile with correct header/colormap... But still something is wrong, the pixeldata contains good data and then a piece of FF 00 FF 00 of the same length and that a few times....

Anybody knows what vb6 does to the imagedata when saving it to SQL2000 ? any tips are welcome.......

Internal Compiler Error: stage 'COMPILE' or 'BEGIN' errors

2006-04-27T08:19:00.000+02:00

It happens sometimes, stupid bug in VS 2003? Most of the times it is one function that has a type error that for some kind of reason is not seen by the compiler (like DataRow myDataRow = new DataRRow();). Simply restart VS and look through your code and fix the mistyped stuff in the function......

Installing IIS After .NET Framework

2005-12-30T15:36:00.000+01:00

If you install IIS after .NET framework or if you removed and reinstalled IIS on a server that has .NET framework, then your ASP.NET pages will not work.
This is because you are missing the IIS mappings associating the ASP.NET file extensions.

To fix IIS mappings for ASP.NET, follow these steps:

1. Click Start -> run -> cmd - ENTER
2. At the command prompt, type the following, and then press ENTER:
"%windir%\Microsoft.NET\Framework\version\aspnet_regiis.exe" -i

In this path, version represents the version number of the .NET Framework that you installed on your server. You need to replace with the actual version number when you type the command.

3. Register the Aspnet_isapi.dll by clicking start -> run
4. In the Open text box, type "regsvr32 %windir%\Microsoft.NET\Framework\version\aspnet_isapi.dll" and then press ENTER

IIS Virtual Directory Bug, VDir in VDir sometimes hidden (invisible due security?)

2005-12-14T11:44:00.000+01:00

The VDir (in another Vdir) will be correct created with no errors, but most of the time the VDir isn't visible in IIS?!?
Although it isn't visible, you can reach it! (example): http://localhost/VDIR/VDIR/something.aspx no error!!!
It looks like there is an User interface bug that hides the VDIR for some reason (security issue?)

So if you want to change options of that VDIR, you have to install MetaEdit (Tool for editing the IIS Metabase)
(install-link + more info)

Some other people had the same problems (source-url)

Adding a Visual basic (vbs) script into a web setup project to add a virtual directory in ISS

2005-12-08T17:12:00.000+01:00

Beneath there is a possible solution for the problem, but visual basic scripting is not good for using in setup projects (sometimes virusscanners block it!)

Because of the strange bug in IIS (look here), I used vbs to make the virtual dirs. But there is a better way, create & configure the Virtual Directory's
in a class that will run during setup:

< RunInstaller(True)> Public Class WebInstaller Inherits System.Configuration.Install.Installer
' Some Component Designer generated code
Public Overrides Sub Install(ByVal state As IDictionary)

' Write here code to do during setup (creating Vdirs, .....)

End Sub

Look at the url below to read about "Customizing Windows and Web setup projects"

All about Installers - Customizing Windows and Web setup projects &
Conditional Install of Desktop and Quick Launch Shortcuts

You must create a virtual directory linked to a path in a script, because in a web setup project it isn't possible to create a virtual dir linked to a path

Also I had to set some options of that directory:

Set Directory Settings to Integrated Windows authentication (without Anonymous access):
IIsWebVDirObj.Put "AuthFlags", 4
(All the AuthFlags" options:

http://msdn.microsoft.com/library/en-us/iissdk/html/14b96ff9-94e6-49f4-8d61-160111041bd5.asp)
(Tip: if you want to combine security setting, like Integrated Windows authentication AND Anonymous access, set

the AuthFlags to 4+1 , the 1 from Anonymous authentication)

IIsWebVDirObj.Put "Path", "C:\Program Files\Unique World Software\InfoView"
This is the path where the virtual directory is referenced to

Set the Read Access to true
IIsWebVDirObj.Put "AccessRead", True

Set the Script Access to true
IIsWebVDirObj.Put "AccessScript", True

ASP.net error: "The resource cannot be found" because of a stupid "/" in IIS configuration (home directory, local path ) !

2005-12-07T14:15:00.000+01:00

When I was testing a Web Setup project I always get a strange error (after the installation):

Server Error in '/TEST' Application.
--------------------------------------------------------------------------------
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested Url: /TEST/Index.aspx
-------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:1.1.4322.2032; ASP.NET Version:1.1.4322.2032

The /TEST/Index.aspx file exist in the right path on my hard disk, so I went on searching and I found out that there were several people which had the same error-problem!

I find the solution (link) :

Under the root path in IIS configuration, under "Home Directory"
under the field "local path". "c:\inetpub\mywebsite\" is not the same
as "c:\inetpub\mywebsite" apparently now. My site came back alive as
soon as I removed the trailing backslash so that the path now says
"c:\inetpub\mywebsite"!

So you see that a stupid backslash can do harm!

Javascript helps you, to go to an anchor on your webpage

2005-11-30T15:39:00.000+01:00

This function (VB. NET) uses javascript to navigate to a specific anchor on your webpage,
This function is only for navigating to #convert, but you can easy change the function offcourse:

If anybody knows how this is possible in ASP.NET, let me know, I'm not a freak yet

Setting the description of a Windows Service isn't possible? [UPDATED: yes it is!]

2005-11-30T10:58:00.000+01:00

When I did my first Windows Service, everything was going smooth.

Only stupid thing that I didn't find out was how to set the description text (visible in service overview).....
Something I find was the ServiceProcessDescriptionAttribute, but I didn't find out how to link it with the service

Blogs that also mention this problem:
