    Call function undirectly

    I am programming an executable application (not a dll or any kind of library). I simply want an equivalent of calling function using GetProcAddress and not just a simple typedef because that method didn't seem to work for executable but only for dll developments. Here is a working example:

    typedef HRESULT (*pCoInit)(LPVOID);
    pCoInit CoInit = (pCoInit)GetProcAddress(LoadLibrary("ole32.dll"),"CoInitialize");

    CoInit will be called instead of CoInitialize.

    But when I try this code to generate an executable, when I double click the executable the program crashes. So I don't know if their is an alternative to GetProcAddress which can be used to build executable and not a dll. Also I don't know if loadlibrary can be used to load from a static library rather than a dynamic one or no, example ole32.lib instead of ole32.dll ?

    A static library is linked to your code, so LoadLibrary doesn't make sense as it's part of the executable and already loaded.

    If you already know the function's name, why do you want to call it using GetProcAddress?
