getclassname and getwindowtext help

closed account (zwA4jE8b)
I am trying to get the open window class names and caption enumerated.
Right now (line 27) is outputting numbers. How do I get a string (the class name)? I am also having trouble with getwindow text function. What datatype do I use to store the text? I am using LPWSTR but I keep getting an uninitialized error.

This is a windows specific question, so move it to windows section.

TCHAR tchWndText[128];
GetWindowText(hwndWnd, tchWndText, 128);


and you will the text of the window having handle hwndWnd in techWndText.
