Paul, Have you considered using the BS_ICON style instead? Icons directly
support transparency and they're really easy to use.
Set the button style to "icon", and in the initialisation have a few
lines of code like this to set the icon on the button:
HWND hUp;
hUp = GetDlgItem( hDlg, IDC_UP );
/* Assign the icon for the up button */
HICON hU = LoadImage( g_hInstance, MAKEINTRESOURCE( IDI_UP ),
IMAGE_ICON, 0, 0, LR_DEFAULTCOLOR );
SendMessage( hUp, BM_SETIMAGE, IMAGE_ICON,
(LPARAM) (DWORD) hU );

How to implement TRANSPARENT Bitmap Buttons Paul- The answer is kind of long, but the short answer is that you create a bitmap
with a specific colored background. Then you can mask it onto the button.
Try looking at how MFC does it with toolbars. Search for "toolbar
TBSTYLE_TRANSPARENT imagelist" in MSDN.
Good luck.

How to implement TRANSPARENT Bitmap Buttons Thanks for the solution, yes it works fine under NT. But Windows CE does not support BS_ICON, and the image size of ICON is limited. Is there any other way? Best Regards,

How to implement TRANSPARENT Bitmap Buttons You could always ownerdraw the button yourself... I've done this on CE, and it works quite well. Quote:

Paul, Only more involved ones where you need to use bitmaps, there are
examples on MSDN if you search for "transparent NEAR bitmap".

How to implement TRANSPARENT Bitmap Buttons I use an owner-draw button, and then use DrawIconEx to draw the icon. This is a case where CE is not lacking the feature, but rather offers only
one way to do it rather than two or three. (Another example would be the
absence of FrameRect, which is, after all, only a convenience function.
There are many others.)

How to implement TRANSPARENT Bitmap Buttons Paul, Windows CE supports the following function:
TransparentImage(); // Windows CE 2.0 and latter
which transfers a bitmap, omitting the portions drawn in a specified color.
You can use this function along with an Owner Draw button to get the results
that you desire.
I hope this helps!
