      Hello,

       

      i hope any body can help me ;-)

       

      i develop a Visual Studio Add-in in C# and i work with Visual Studio 2005 and 2008. In Visua Studio 2005 i hafe createt a custom ToolWindow with the Method Windows2.CreateToolWindow2, After creating the ToolWindow and before i set the ToolWindow to visible = true, i set the tab picture with a 24-bit 16x16 Bitmap. In Visual Studio 2005 it will works fine but in VS20008 the method Window2.SetTabPicture throw a Argument Exception with the message "Value does not fall within the expected range".

       

      I know, the background color for the Bitmap in Visual Studio 2008 to 0,254,0 is different than Visual Studio 2005. But it will not work, in Visual Studio 2008.

       

      is this a bug in Visual Studio 2008 Beta2?

       

      Many thanks for all help!!!

      For your description I guess that you already read this thread:

      The strange part is that with VS 2008 Beta2, if you use a 24-bit 16x16 bitmap with RGB=0,254,0 as background, it should work, as it worked in VS.NET 2002/2003, but not in VS 2005, when you have to use RGB=255,0,255 as background color.

       

      My MZ-Tools add-in uses a native resource Dll with 16x16 24-bit bitmaps with RGB=0,254,0 as background and I have notes in the code like this:

       

      iSatelliteDLLHandle = Me.LoadSatelliteDLL()

       

      #If VS_7_0 Or VS_7_1 Then

         objPicture = TransparentPicture.GetTransparentIPictureDispFromDLLResource(iSatelliteDLLHandle, iImageIndex)

         objWindow.SetTabPicture(objPicture)

      #ElseIf VS_8_0 Then

         objBitmap = TransparentPicture.GetTransparentBitmapUsingMagentaFromDLLResource(iSatelliteDLLHandle, iImageIndex)

         objWindow.SetTabPicture(objBitmap.GetHbitmap)

      #Else

      ' Using the technique of VS 2005 causes an exception (argument outside of expected range) so we use the VS.NET 2002/2003 approach again

         objPicture = TransparentPicture.GetTransparentIPictureDispFromDLLResource(iSatelliteDLLHandle, iImageIndex)

         objWindow.SetTabPicture(objPicture)

      #End If

       

      Where the functions for VS2008 are:

       

      Friend Shared Function GetTransparentIPictureDispFromBitmapHandle(ByVal hIntPtr As IntPtr) As stdole.IPictureDisp

       

         Dim objPicture As Object

         Dim objGuid As New Guid("00020400-0000-0000-C000-000000000046")

         Dim iResult As Integer

         Dim tPICTDESC As New PICTDESC(hIntPtr)

       

         iResult = OleCreatePictureIndirect(tPICTDESC, objGuid, 1, objPicture)

         Return CType(objPicture, stdole.IPictureDisp)

       

      End Function

       

      Friend Shared Function GetTransparentIPictureDispFromDLLResource(ByVal iDLLHandle As IntPtr, ByVal iResourceIndex As Integer) As stdole.IPictureDisp

       

         Dim iBitmapHandle As Integer

         Dim objPicture As stdole.IPictureDisp

       

         If Not iDLLHandle.Equals(IntPtr.Zero) Then

           iBitmapHandle = LoadBitmap(iDLLHandle, iResourceIndex)  ' Win32 API Call

           If iBitmapHandle <> 0 Then

              objPicture = GetTransparentIPictureDispFromBitmapHandle(New IntPtr(iBitmapHandle))

           End If

         End If

       

         Return objPicture

       

      End Function

       

      So, I am not sure why is not working in your case...
