    Hi, I have trouble with this type, need help. Consider this function declaration:

    SCODE SetData(VARIANT FAR* pData)

    What I have is a sample code which reads in data from a file and works just fine. A COleSafeArray is passed to the function as follows:

    COleSafeArray osa;
    SAFEARRAYBOUND sab;
    sab.cElements = file.GetLength();
    sab.lLbound = 0;
    osa.Create(VT_UI1, 1, &sab);

    void* buffer;
    osa.AccessData(&buffer);
    file.Read(buffer, file.GetLength());
    osa.UnaccessData();

    SetData(osa);

    I want to pass a string to this function and can't figure it out how. Please help. Bunburry
