Copies the CWnd caption title (if it has one) into the buffer pointed to by lpszStringBuf or into the destination string rString.
int GetWindowText( LPTSTR lpszStringBuf, int nMaxCount ) const; void GetWindowText( CString& rString ) const;
- Points to the buffer that is to receive the copied string of the window's title.
- Specifies the maximum number of characters to be copied to the buffer. If the string is longer than the number of characters specified in nMaxCount, it is truncated.
- A CString object that is to receive the copied string of the window's title.
Specifies the length, in bytes, of the copied string, not including the terminating null character. It is 0 if CWnd has no caption or if the caption is empty.
If the CWnd object is a control, the GetWindowText member function copies the text within the control instead of copying the caption.
This member function causes the WM_GETTEXT message to be sent to the CWnd object.
See the example for CWnd::SetWindowText.
