So... i want to know, if that is posible?... make a .dll with some functions (Memory functions) for use in C#?... I mean, add the reference and that's all. What would be my limitations?. I know that in C# is feasible (i already have created one), but in C++ don't know. tyvm. _________________ Excuse me if you don't understand what I just said, but "english" isn't my native language.

Of course you can
but you should declare the function as:

Code:

__declspec( dllexport ) void myfunc( params . . ) {
// etc
}

and then create a definition file for each function that should be exported from the dll
the .def file should look like that

Code:

LIBRARY MYDEF
EXPORTS
myfunc @1
myfunc2 @2
// and so on . .

at the end, in your C# project use [DllImport("mydll.dll")] as usual

no, since it's not a managed code
you can import the function using the following code

Code:

[DllImport("dllname.dll")]
public static extern myfunc( params . . );

then call it anywhere from your code
