Syntax
BOOL SetWindowText( HWND hWnd, LPCTSTR lpString );
Parameters
hWnd
Handle to the window or control whose text is to be changed.
lpString
Long pointer to a null-terminated string to be used as the new title or control text.
Return Values
Nonzero indicates success. Zero indicates failure. To get extended error information, call GetLastError.
Remarks
If the target window is owned by the current process, SetWindowText causes a WM_SETTEXT message to be sent to the specified window or control. If the control is a list box control created with the WS_CAPTION style, however, SetWindowText sets the text for the control, not for the list box entries.
The SetWindowText function does not expand tab characters (ASCII code 0x09). Tab characters are displayed as vertical bar (|) characters.
