    Help with hitting 'enter'

    Hello guys!

    I'm making a chat application, everything works fine except for that you have to hit the "Send" button with your mouse allways, and you can't use "Enter" to send the message.

    So I'm asking you guys, how would it be possible to allow the enter button to like call some function or make it "click" the Send button?

    I'm using the Win32 API, c++ of course

    Thanks in advance,
    K-Zodron

    I would handle WM_CHAR messages.. and then respond to '\r'


    Code:
    case WM_CHAR:
        
         switch(wParam)  
         {
              case '\r':  
    
              [respond to ENTER key]
    
              return 0;
    
              [Handle other cases of escape characters...]
    
         }

    Thanks..but it doesn't work really :\
    When I hit "enter", it doesn't call the function I set it to call, and that shows it doesn't really work.

    Maybe I put it in wrong place (:P) ?
    (In WindowProcedure or smth, at least it has many WM_ cases <.<)

    Didn't help

    Edit: When I changed the WM_CHAR to WM_KEYUP, it works just fine untill I decide to write something on the chat box(I have a default value there, and that gets 'said' when you hit enter before doing anything else)
