help with windows transparency

[Guest]

hello, i am trying to create a form with the shape of a bitmap, like media
player can do. i know that there is a bug with the TransparencyKey property
and 32bpp mode. so i tried the workaround provided on msdn but it doesnt
work. could someone please tell me what im doing wrong? i am using windows
xp. here is my code.

Bitmap bmp = new Bitmap("Body.bmp");
bmp.MakeTransparent(bmp.GetPixel(0, 0));
BackgroundImage = bmp;
this.TransparencyKey = bmp.GetPixel(0, 0);

now this does make the proper color transparent (which is at 0,0 on the
bitmap), but it also makes pure black (RGB(0,0,0). why would it do this?

thanks in advance.

i forgot to mention. the transparent color at 0,0 is bright yellow, so thats
not why the black is transparent too.

ugh, i still cant get it. i cant figure this out. does anyone have any idea?
no matter what the pure black is always transparent and it shouldnt be.

Have you seen this bug report? It looks like it's related:

http://lab.msdn.microsoft.com/produ...edbackid=e4348039-5eee-4e56-a39f-b246dabaeef0

The bad news is that this bug was reported in July, and MS has responded
that they know it's a real bug, but they don't consider it an important
enough bug to fix at this time. And that was 5 months ago...
