Retrieves the specified window's class name.
OutputVar := WinGetClass(WinTitle, WinText, ExcludeTitle, ExcludeText)
The name of the variable in which to store the retrieved class name.
A window title or other criteria identifying the target window. See WinTitle.
If present, this parameter must be a substring from a single text element of the target window (as revealed by the included Window Spy utility). Hidden text elements are detected if DetectHiddenText is ON.
Windows whose titles include this value will not be considered.
Windows whose text include this value will not be considered.
Only the class name is retrieved (the prefix "ahk_class" is not included in OutputVar).
Window titles and text are case sensitive. Hidden windows are not detected unless DetectHiddenWindows has been turned on.
MsgBox "The active window's class is " WinGetClass("A")
