TaskDialog MainIconHandle

I'm having a problem with the TaskDialog MainIconHandle.  I'm trying to assign a 32 pixel icon to the TaskDialog MainIcon and it will not show.  While I can get the icon to show using the API method provided in the example, I cannot see why CodeJock's own control cannot deliver the handle.  The code I am using is,

   
    Dim imgIcon As ImageManagerIcon, lngIconHandle As Long
    Dim td as TaskDialog

    Set imgIcons = MyForm.cjImageManagerIcons
    Set imgIcon = imgIcons.Icons.GetImage(ID_TASK_DIALOG_ICON, 32)
    lngIconHandle = imgIcon.Handle
 
    Set td = MyForm.cjTaskDialog
    With td
        .MainInstructionText = "CJ image handles do not work."

        .MainIcon = xtpTaskIconCustom
        .MainIconHandle = lngIconHandle
        .ShowDialog
     end with

    Set td = Nothing
    Set imgIcon = Nothing: Set imgIcons = Nothing

The only thing showing up on the TaskDialog is the MainInstructionText.  The image in the ImageManagerIcons is an XP icon with multiple sizes.  Is there something I'm missing?  Thanks for your help.

Sincerely,

John
   

Aaron, thank you for the solution. 

A caveat to everyone who is trying to accomplish the same thing, you cannot use an icon with an alpha channel with the StdPicture object.  Initially when I implemented the solution it didn't work.  After removing the icon with the alpha channel from the ImageManager and substituting an icon with 256 colors it worked beautifully.  The weak link here is the StdPicture object which does not support icons with alpha channels.  Again, Aaron thanks for your help.

Sincerely,

John

McKloony, I don't know if 48 x 48 icons will work.  Sorry. 

If not, it would be a limitation of the TaskDialog, but probably by design.  When CodeJock created the TD control, I am sure they built it within the design specs supplied by Microsoft.

Cheers,

John
