    Need to capture the enter key

    Hi, I have a single line editbox that users of my program will type commands into to perform certain tasks. How do I capture the enter key so I know when to grab the text they typed in for processing and then empty to editbox? I can do everything except capturing the enter key.

    Thanks

    a search would have found this as I have posted it many times.........

    Yes I know that part already, however, what windows message is received when the enter key is hit? This information I haven't been able to find out on my own.

    okay, but I tried checking it for VK_ENTER and I got an error saying that VK_ENTER wasn't defined. Do you know why this is?

    VK_RETURN, maybe?

    Okay can someone help me with some other problem I am having? I use the following code in my windows procedure:

    Code:
    case WM_KEYDOWN:
    	hFocus = GetFocus();
    	if( hFocus == status.CmdLine || hFocus == status.hWnd ) { // if hWnd has focus.. CmdLine truly has it
    		if( wParam == VK_RETURN ) {
    			// get text inside editbox
    			// pass text into Command()
    			return(0);
    		}
    	}
    	break;
    This code works and all except that now it wont allow me to enter any text into the editbox (which completely defeats the purpose). Any help would be appreciated.

    If the key wasn't a return, you should really pass the input onto the default handler, rather than just eating the keystroke (which is why the edit control never sees anything)
