I Created an edit control with CreateWindow(TEXT("EDIT")...) and input some charactors(such as "12345"),so, the cursor is behind the charactor '5',
then, change the cursor position and put the cursor before '4',then I can get a message,the value of message is 0x119,the wparam of this message is 0x007,and lparam is 0x6903a, so , what's this message mean and what's the wparam and lparam mean??
