SetProp The SetProp function adds a new entry or changes an existing entry in the property list of the specified window. The function adds a new entry to the list if the specified character string does not exist already in the list. The new entry contains the string and the handle. Otherwise, the function replaces the string's current handle with the specified handle. BOOL SetProp( HWND hWnd, // handle to window LPCTSTR lpString, // atom or string HANDLE hData // handle to data ); 找找msdn,上边都有介绍的
