Load 32bit DLL library in 64bit application

dll loadlibrary getprocaddress

Is there a way to load a 32bit DLL library (something with the same usage as LoadLibrary) I would like to use that function along with GetProcAddress.

I looked at WOW, but it does not seem to offer the functionality. The functionality should exist, since tools like DependencyWalker are able to read the symbols of a 32bit dll even though its 64bits.

thanks

Sorry, but you can only load a 32bit DLL into a 64 bit process when you are loading the dll as a datafile. You can't execute the code. http://support.microsoft.com/kb/282423

Microsoft recommends that you use interprocess COM to use 32 bit code with a 64 bit application. Here's an article explaining the process http://blog.mattmags.com/2007/06/30/accessing-32-bit-dlls-from-64-bit-code/ Its not fun.
