If you refer to the Msg parameter in the SendMessage API:
LRESULT SendMessage(
HWND hWnd, // handle of destination window
UINT Msg, // message to send
WPARAM wParam, // first message parameter
LPARAM lParam // second message parameter
);
the answer is no.
The Msg parameter must be a UINT.
For the particular Windows message WM_CLOSE, the value is defeined in
winuser.h
as 0x0010, in hexadecimal form.
#define WM_CLOSE 0x0010
However you can convert an AnsiString such as
const AnsiString WMClose="WM_CLOSE";
using either a map or a function.
