The GetWindowText function copies the text of the specified window’s title bar (if it has one) into a buffer. If the specified window is a control, the text of the control is copied.
int GetWindowText(
HWND hWnd, |
// handle of window or control with text |
LPTSTR lpString, |
// address of buffer for text |
int nMaxCount |
// maximum number of characters to copy |
); |
If the function succeeds, the return value is the length, in characters, of the copied string, not including the terminating null character. If the window has no title bar or text, if the title bar is empty, or if the window or control handle is invalid, the return value is zero. To get extended error information, call GetLastError.
This function cannot retrieve the text of an edit control in another application.
This function causes a WM_GETTEXT message to be sent to the specified window or control.
