- DrvQueryFontTree fails with Splwow64.exe
- Posted by SL on June 24th, 2005
OS: Windows XP Professional x64 Version 2003 Service Pack 1
DDK: Windows DDK 3790.1830
Case: Printing from a 32-bit application
DrvQueryFontTree returns a pointer to an FD_GLLYPHSET structure.
After that ntdll.dll fails. Following is the call stack information:
“ntdll.dll!RtlCopyMemory () + 0xb0 bytes”
When the application that prints is a 64-bit application, there is no
failure
even though the content of “FD_GLLYPHSET” structure seems to be identical
with the one from printing from 32-bit application.
