You can: 1) Load programmatically the DLL using LoadLibrary(). In this case you have to load the functions entry points the dll exports via GetProcAddr() 2) Usually DLLs come with a LIB file. Include the LIB file into your project. The functions exported by the DLL are now available. 3)Use the delay loading feature with the /delayload:dllname linker switch

[_AnsHUMAN_]

Use CoCreateInstance() You should know how to invoke a COM and work with COM objects.This applies when you have the class id of the interface. else You can also use LoadLibrary() alongwith GetProcAddress() to invoke the functions Somethings seem HARD to do, until we know how to do them. ;-) _AnShUmAn_ -- modified at 6:18 Tuesday 13th June, 2006

Try GetModuleHandle which returns the handle of your DLL through which you can get the addresses of the method using GetProcAddress.. The GetProcAddress Fails when the method is Mangled (in case of C++ Dll). Knock out 't' from can't, You can if you think you can :cool:

in project setting , under link tab give reference to the .lib file, give its path. in your program add the header file.. header file should have __declspec (dllimport) not __declspec (dllexport) go get going.
