Re: How to convert from OLE_COLOR to COLORREF

This means the color is part of a palette I would say. And you are right you

need to get handle to that palette. But even if you have it you need to

look-up the palette yourself because OLETranslateColor still gives you back

0x0100XXXX. For more information about input & output values look into MSDN

under OLETranslateColor.

Sorry can't help on this...
