Hi Christof,

One more thought. Are you sure that a string is always passed by reference? I don't think so. Try this, declare GetProfileString() and don't declare the return buffer as being passed by reference, and don't pass it that way. The return value will indicate that characters have been written to the buffer, but the string will be empty on return. You have to explicitly declare it that way, once you do and pass it by reference, you get the same return value, and that many characters in the string.
