Hello,

I have a simple question: can I have more than one bitmap resource in the
BITMAPS_BEGIN/BITMAPS_END section of a ctc ?

that is something like that:
BITMAPS_BEGIN
guidMyPkg:IDB_MENU_IMAGES, bmpPic1, bmpPic2, bmpPicSmile, bmpPicX,
bmpPicArrows;
guidMyPkg:IDB_MYIMAGES, myBitmap;
BITMAPS_END

Because I tried such a configuration and it does not seem to work as
expected. Indeed, while the bitmap "IDB_MYIMAGES" is added to the resx file
with the correct id, the button that should be associated with the first
bitmap of IDB_MYIMAGES (via "myBitmap") displays the first bitmap of
IDB_MENU_IMAGES. (As a workaround, I added my new bitmap to the default
bitmap strip and it works).
So I am wondering if multiple bitmap resources is supported within the
BITMAPS section of a ctc file.

Thanks,

Patrick

Hi Patrick,

I consulted this problem with our product team, they confirmed it is
possible to have more than one bitmap, but the bitmaps must have unique
GUIDs (and, unfortunately, the compiler doesn't warn when a GUID is
re-used).

It looks like you're re-using the package GUID for each of your bitmap
strips. You should generate a new GUID for each of these bitmap strips.

The GUID for a bitmap is what identifies the strip unlike all other items
which are identified by GUID:ID pair. The ID here indicates where to get
the data later when it needs it from the resources of the dll where the
command table binary is stored. When you reference it in a button it is
also not a GUID:ID pair but the strip GUID and the slot number in that
strip. For this reason and to avoid symbolic name collision we recommend
that every strip be given a unique GUID that is not associated with
anything else.

Thanks!

Best regards,

Gary Chang
