Problem with images???

[al]

Greetings,

I have this problem with any image, in any format, I include in
ToolBar Control. Those images are in-house developed. The problem is
when I include an image in a ToolBar and have its Enabled property set
to False, at runtime, the image just disappears, leaving a square
grayed area with nothing inside it. ( while it is supposed to show the
image in gray color)??


MTIA,

That's a known "limitation".

<msdn>
If the image or text has multiple colors, they display in a monochromatic gray.

Does this also happends if you have a chess-board like
image? All colors that are light will turn into grey, and
all dark color will be darker gray. Maybe your image
doe'snt contain any color that is dark enougth?

Hi,
I had similar problem just few days ago. The reason for my problem was that
my toolbar was placed on a panel instead of being placed directly on the
form.
Toolbars have a limitation that they should be placed on form directly and
not on any other control. (check here:

If you place the toolbar directly on the form the images should show
properly.

The strange thing is this type of behavior dosen't occure when I
import system-images (images the come with Win2k) into the toolbar.
Could I have done someting wroing when I first draw the images (they
are your basic MoveFirst and MoveLast images that I could not find in
Win2k)??
