Images does not show on toolbar button at runtime

[Dotnetjunky]

Hi,

I encountered a very strange behavior in my WinForms app
today (I used VB.NET.) I have a Toolbar control, which is
associated with an ImageList control. Each button on the
toolbar points to a corresponding image of the ImageList.
At design time, VS.NET shows the images on toolbar
buttons properly; but at runtime, all the images
disappear, leaving me blank buttons.

Anybody knows the cause of this problem ?

Thanks in advance.

If you are using Windows XP Visual Styles, call 'Application.DoEvents'
directly after calling 'Application.EnableVisualStyles'.

thanks a lot, that works.

And one more question also regarding images on toolbar
buttons. How can I make a portion of the images
transparent ?

Happy New Year

Have a look at the imagelist's 'TransparentColor' property.
