But in the above I am getting Handle of   GetImage.CreatePicture    which is just a single image, so I would have thought it would be OK. But it doesn't work.  However, if I assign    GetImage.CreatePicture  to an Object, and then use Handle of the Object, it works fine.

Anyway it works, so I will not worry.
All the images I have been using are 32bit alpha.
Thanks again for your help.

Hi Chris,
 
  1. You have to replace Image with Picture
  2. Oleg said and I quote:
    "As we wrote in release notes for 11.2.1, ImageManager now have only 2 GDI Bitmaps that contains all icons. So developers can have 1000 icons in single image manager and don't worry about GDI objects number. So now Handle return common bitmap handle :( "             So .Handle returns the BitmapHandle and will be always the same.  
 
btw. Did you test it (what I previous wrote) with alpha images?

Hi Chris,
 
I believe you can't assign images larger than 32x32.

Hi Chris,
 
ImageManager contains only ONE Bitmap and that's why it returns always same handle. There's a post somewhere in CJ forum about this...
 
Well, it works for you (and me)

Additional Question.

It looks as if the TaskDialog always resizes the icon to a fixed size. I don't suppose there is any way to have larger icons displayed.....?

Thanks Aaron, that works fine.

I had previously tried dropping a PictureBox on the form and using:
   Set Picture1.Picture = ImageManager.Icons.GetImage(ID, 32).CreatePicture(xtpImageNormal)
   TaskDialog.MainIconHandle = Picture1.Image.Handle

The PictureBox correctly displayed the icon, but TaskDialog did not.

So as you suggest I tried using:
    Dim Pic as Object
    Set Pic = ImageManager.Icons.GetImage(ID, 32).CreatePicture(xtpImageNormal)        ' Exactly same as above
    TaskDialog.MainIconHandle = Pic.Handle

And TaskDialog now correctly shows the icon. :-)


?? I do not understand why my
  TaskDialog.MainIconHandle = ImageManager.Icons.GetImage(ID, 32).CreatePicture(xtpImageNormal).Handle
      does not work  (ie. without going through the intermediate Object).

Anyway, problem solved. THANK YOU Aaron.

Hi Chris,
 
This will work:
 
    Dim stdPic As Object 'See Note 1.
    'Dim stdPic as StdPicture 'See Note 2.

    Set stdPic = ImageManager.Icons.GetImage(0, 32).CreatePicture(xtpImageNormal)
   
    With wndTaskDialog
        .MainInstructionText = "Some text...."
        .MainIconHandle = stdPic.Handle
        .MainIcon = xtpTaskIconCustom
        .ShowDialog
    End With
 
 
Note 1. //this will work also but: see post https://forum.codejock.com/forum_posts.asp?TID=12868
 
Note 2. //this will work also but: see post
 
 
With second option it isn't clear if this will support alpha images (first one doesn't), well see for yourself in post and maybe you will get a reply from support

I have some icons loaded into an ImageManager control, on same Form as TaskDialog control, but I cannot get the Dialog to show icons from the Image Manager.  Here is what I am trying:

TaskDialog.MainIcon = xtpTaskIconCustom
TaskDialog.MainIconHandle = ImageManager.Icons.GetImage(100, 16).Handle




The TaskDialog displays my text and works OK, but no icon. Can you tell me what is wrong?

Thanks to Aaron for explaining I need to use an intermediate Object.
