This program gets information about the classes that make up a root window with a title containing some target text. For example, you can look for a form with a title containing the text "Notepad."
When you enter the text to find and click the Find Windows button, the program saves the target text in the global variable g_Contains and then calls the EnumWindows API function to enumerate the system s windows.
