I am having difficult time drawing a image using Visual Studio Image Editor.

I can draw the image and save it as .bmp file load it into a pictureBox
image

but when the program is run the background of the bmp is not Transparent.

How can I achieve a transparent background?



Thanks

The bitmap format has no alpha, therefore no transparency. You should try a
gif, tiff, or icon.

How do you then make a 32bit bitmap transparent? Does Visual Studio save
bitmaps in 32 bit format. How do you convert another format to 32bit format?
 
Well, I have tried creating the drawing using the following formats with no
success

..gif, .tiff. and .icon



What program would I use to draw a 32 bitmap?



This drawing will be loaded into a pictureBox. Is this the correct control
for these image types?

Do you have the background of the picturebox set to transparent?

Are you placing the image in the background property? or the imagfe
property. I belive the Background doesn't support transparency. But placing
the image into the image property. it will have transparency.

Give it a try.

Only stable success I have had with transparent background images in picture boxes
was with either proper 32 bit "XP Style" icons (other icons don't work), or .png
format images created in PhotoShop with a transparent background. With the .png
images, they only seem to work properly when loaded into a picture box from a
resource at runtime. In Design, there is usually no transparency (which may change
with SP1) and usually no transparency at runtime if loaded in Design.

Gene, I have tried loading the image using Application.StartupPath & "\" &
myFileName.
The image loads just fine but still no transparent background.

It sounds like the image you are trying to use is not a proper 32 bit image with a
transparent background versus a 24 or 32 bit image with a non-transparent background.
This has nothing to do with transparent key color by the way.
