Hi,

Some time ago I wrote a PrintMonitor-DLL for 32bit Windows. Now I tried to port it to win64 using the svn-Version of FPC (did a checkout two days ago)
When I check the resulting DLL using Mitec-EXE-Explorer everything looks fine. The Main-Section of the DLL gets called, as well as the function InitializePrintMonitor which is exported by the DLL. This function returns a pointer to a Structure containing the addresses of some other functions.

For Win32 I compile with -Pi386 -TWin32, for Win64 I use -Px86_64 -TWin64

The resulting DLL works like a charm on Win32 and will crash the spooler on Win64.

Unfortunatly I was not able to produce a version of the source I can release without running into copyright issues, as I use some code contributed by someone else.

Perhaps someone has an idea what I could have missed? Are there any open issues compiling DLLs for Win64?

regards
Lukas
