What is GetWindowText?
GetWindowText is a function in the Windows API that is used to retrieve the text from a specified window. It takes a window handle as a parameter and copies the current text of that window into a buffer provided by the calling application.
Some key things to know about GetWindowText:
- It is declared in the Windows.h header file
- The window text that it retrieves can be things like the window title, content in an edit control, or other text displayed in the window
- The caller must allocate the buffer to receive the text and pass the buffer's address and size
- GetWindowText will copy up to the specified number of characters, or the entire text if the buffer is large enough
- The function returns the length of the retrieved string, excluding the null terminator
- It can be used with standard windows controls like buttons, edit boxes, list boxes etc to get their contents
GetWindowText is commonly used by programs to get information about other application windows. Some examples of using it are: getting the title of another app's window for identification, reading text from controls in a window to gather data, saving text contents before closing a window, automation and testing of applications.
