Hi,all:
In the LRESULT SendMessage(
  HWND hWnd,      // handle of destination window
  UINT Msg,       // message to send
  WPARAM wParam,  // first message parameter
  LPARAM lParam   // second message parameter
);
Which value can be used about "Msg" parameter? Enum a sample such setting
the CListCtrl control item value,please.

Are you perhaps asking about LVM_SETITEM?

Any of the LVM_ values (LVM stands for List View Message, and the
CListCtrl is a wrapper round a Windows List View common control) which
are defined in the common controls header file, and which you'll find
in the documentation, together with details of what the parameters
mean. Ordinary WM_* windows messages will also work, but are less
likely to be useful.
