This is consistent with not including libpq, so nothing weird there.
Note: You can just add the lib file as a dependency in your project
explorer if I'm not mistaken - that easier than going through project
properties.

Your project is set to use "Debug Multithreaded". That conflicts with
libpq. You will need to use "Multithreaded using DLL" (it may work with
"Debug Mulithread ed using DLL" - I'm not sure about that).

If that's not pssible, you will need to recompile libpq with the same
settings your program uses.

hi Magnus....

It compiled and Linked properly after mentioning "Debug Multithread ed using
DLL"But i faced problem while executing it....
Simply i gave in Configuration properties-> Linker->Input-> ignore library
the library name "LIBCMTD.lib"
Then it worked fine.......
Any thing wrong in this?
Just to inform the solution to your view.....

Thanks,
Sandhya
