Calling function defined in DLL lib

[pukiamak]

Hello guys,

How can I call the function defined in Dll in Visual Studio?
I have tried using this macro

#define DllImport __delspec(dllimport)
DllImport FunctioName

but visual studio say it's unresolved external symbol. I have tried to go to the project's setting and include the additional libary but no luck. Any suggestion?

Thanks

It is __declspec

I haven't used DLL's much in my projects, but I think you need to use LoadLibrary() and FreeLibrary().

Creating the DLL
When the DLL is created, the routines should be prefixed with __declspec(dllexport). This will create 2 files: a .lib and a .dll.

Creating the program that uses the DLL
The routines should be prefixed with __declspec(dllimport)

Linking the program
Add the .lib created by the dll to the link line

Running the program
Make sure the .dll is either in the same directory as the .exe or somewhere in the PATH
