Working with DLL's 1

[jerasi]

I am working on an Extended Stored Procedure and i need to call funcions from another dll file, how do I import (or include) the dll file in my project?

Thank you.

There are three ways of doing it(that I am aware of):
- 1. implicit linking - you need to have the .h and .lib files of of the dll(and the dll itself). you put #include mydll.h in your code and mydll.lib in ProjectSettings->Link->Object/modules

- 2. explicit linking - you need to use the LoadLibrary/FreeLibrary to load the dll and GetProcAddress for every exported function from the dll

- 3. #import - usually for COM dlls (which are being registered with regsvr32.exe). You will need to use the .tlb file of the dll. use "#import" and "using namespace" to be able to create one object with CreateInstance and the use its functions/Interfaces.

Hope this helps, s-)
