The following code is an example of a DLL that was created in Visual C++ by using the Win32 Dynamic-Link Library project type.

You link to the .lib file, include the .h file, and put the DLL in the output directory. This scheme is analogous to calling functions in a DLL, but as if the DLL is also able to call functions inside your C program -- sort of like with a "callback". But unlike with a DLL, you don't use LoadLibrary () and GetProcAddress () to obtain the pointers to the COM object's functions. For calling a function inside a DLL, you need three functions; LoadLibrary, GetProcAddress, and FreeLibrary.

Test your DLLs with another program to ensure that the function (and the DLL) behave correctly. Testing it with the debugger of your compiler or a simple C program in which you can call a function in a DLL will help you identify whether possible difficulties are inherent to the DLL or LabVIEW related.
