    Hello,
    I have a unmanaged fortran dll that Iam trying to load using LoadLibrary
    from manged c++. I have to use loadlibrary, since I dont know the path to the
    dll until runtime.

    I can load the library, get the function pointers etc., but when I call a
    function in the dll, the function succeeds, but the registers in the current
    functions corrupted.

    For example

    void someManagedCppFunction( int *var1 , int *var2) {

    // call fortran dll function via function pointer
    // v1 and v2 are different than Var1 and var2

    double v1, v2;

    int k = fp(v1,v2);

    // At this point the the pointers var1 and var2 are displayed as undefined
    values.

    }

    Your help is apprecited.
    thank you.
