CWnd::GetWindowTextLength
Returns the length of the CWnd object caption title.
int GetWindowTextLength( ) const;
Return Value
Specifies the text length in characters, not including any null-termination character. The value is 0 if no such text exists.
Remarks
If CWnd is a control, the GetWindowTextLength member function returns the length of the text within the control instead of the caption.
This member function causes the WM_GETTEXTLENGTH message to be sent to the CWnd object.
Example
See the example for CWnd::SetWindowText.
