After some more testing, I've found out that it works only if the application code uses the shared version of the C library (msvcrt.dll) That means compiling with the /MD or /MDd options, or in the GUI, selecting in the project settings, C/C++ -> Code Generation -> Use runtime library -> Multithread DLL (or Debug Multithreaded DLL) That's apparently not the default when creating a new application with Visual Studio. libpq.dll must also having been compiled with /MD as well, but that should be the case unless the OP changed that himself in libpq/win32.mak -- Daniel PostgreSQL-powered mail user agent and storage: http://www.manitou-mail.org ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
