this example not working... I did exactly what you wrote ... Any ideas why ?

$Add = DllCall(@ScriptDir &"ExampleDLL.dll", "int", "Add", "int", 10 ,"int", 9)

MsgBox(0,"",""&$Add[0])

OK, here we go. I have attached a C++ source code, I suggest you using VS (2010) to compile it.

You can find the compiled Dll from the Release folder within the attached zip package.

The AutoIt part should be like this:

Global $sum = DllCall('DllExport.dll', 'int:cdecl', 'Sum', 'int', 5, 'int', 5)
MsgBox(0, '', $sum[0])
