Alpha Channel

[Guest]

Does C# Support Alpha Channel Backgrounds? I have an image made in Photoshop, which has an alpha channel. I save it as a PNG file, then set the form's BG image to that file. Now it shows up fine in the designer, but when executed, it appears as a big black square. Anyone have any suggestions.

Hi Bill,

I just tested this with VS 2003 and a .png with an alpha channel used as
the background and my C# winform was transparent for the alpha channel
areas. What do you see when you expand BackgroundImage property of your
form?

I recently uninstalled that, but without exploring it... That supports
speech recognition, for a C# Windows Form Application?

Here is an exact copy of my screen:

The BG image is in PNG format, but none of the BGimage properties are
enabled.
