Hello Jialiang,
From your post, my understanding on this issue is: you want to know how
to resolve the failure of 'PasteFace' when the Office is not an English
version, in addition
No, this one i figured out. I do just the enumeration you suggest below.
you wonder why the button face of the Office add-in
works abnormally when it is disabled. If I'm off base, please feel free
to let me know.
Yes, that is my problem. When I create the DIBs (either 256 color or true
color DIB plus a 2 color mask DIB) I face the problem that Office 2000 apps
show empty command bar buttons. When I enable them the DIBs are correctly
used to draw the transparent image.
For your first question, please refer to the section '2. Transparent
button icon' of the codeproject article:
http://www.codeproject.com/com/wordhighlight.asp. It enumerates the data
formats currently available on the clipboard and tries to determine the
localized format name in m_szFaceFormatName and m_szMaskFormatName.
Yes, I followed that approach.
For your second question, it depends on how you copied the bitmap as
button face. There are several articles describing how to do it properly:
The KB:
http://support.microsoft.com/kb/288771 (How To Create a
Transparent Picture For Office CommandBar Buttons) illustrates the
standard way to copy bitmaps as button face. (see the function
'CopyBitmapAsButtonFace'). Another article
Yes, that is the article I followd for DIB creation.
Would you have a look at the articles above and check the codes again? If
it still cannot help to resolve the problem, would you paste your
"CopyBitmapAsButtonFace" here? And I will help to see where the problem
is.
Here it is:

}
// apply the clipboard data and ensure the button is visible
hr = Button->raw_PasteFace();
hr = Button->put_Visible(VARIANT_TRUE);
// later on I have Button->put_Enabled(VARIANT_FALSE) which causes the
image to disappear.
Thanks for any help on this. So far I just dropped the transparent image
support and use the standard WinXP background color where my images should
be transparent. As I need Office 2000 support only for a minority of
customers this could be a workaround.
