This is a Catch-22. In order to get the class name, you need the window handle. Here's the declaration

DECLARE INTEGER GetClassName IN Win32API;
INTEGER hWnd, STRING @lpClassName, INTEGER nMaxCount

nMaxCount is the length of the lpClassName string.

Another note, all FoxPro windows have the same class name: Fox_4000001.

If I were to guess at the problem you're trying to solve, I'd say it was twofold. One, FindWindow only works if you have the exact title name, and it doesn't work on child windows. Two, you're trying to get the handle of a child window. Am I close?
