Sim bei Enter drücken (Geräusch)

Jochen Kalmbach

Dann bin ich auch überfragt...müsste mich jetzt auch zuerst mal gaaaanz tief einlesen, warum der Beep überhaupt kommt...

Der Beep wird eventuell von IsDialogMessage erzeugt.

Wenn sich Edit-Control also auf einem Dialog befindet, müsstest du glaube ich noch die Nachricht WM_GETDLGCODE behandeln.

nene, ist auf nem normalen window :

HWND hwnd;               /* This is the handle for our window */
    MSG messages;            /* Here messages to the application are saved */
    WNDCLASSEX wincl;        /* Data structure for the windowclass */

    /* The Window structure */
    wincl.hInstance = hThisInstance;
    wincl.lpszClassName = szClassName;
    wincl.lpfnWndProc = WindowProcedure;      /* This function is called by windows */
    wincl.style = CS_HREDRAW | CS_VREDRAW;;                 /* Catch double-clicks */
    wincl.cbSize = sizeof (WNDCLASSEX);

    /* Use default icon and mouse-pointer */
    wincl.hIcon = LoadIcon (NULL, (LPCTSTR)IDI_APPLICATION);
    wincl.hIconSm = LoadIcon (NULL, (LPCTSTR)IDI_APPLICATION);
    wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
    wincl.lpszMenuName = NULL;                 /* No menu */
    wincl.cbClsExtra = 0;                      /* No extra bytes after the window class */
    wincl.cbWndExtra = 0;                      /* structure or the window instance */
    /* Use Windows's default color as the background of the window */
    wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;

    /* Register the window class, and if it fails quit the program */
    if (!RegisterClassEx (&wincl))
        return 0;

    /* The class is registered, let's create the program*/
    hwnd = CreateWindowEx (
           0,                   /* Extended possibilites for variation */
           szClassName,         /* Classname */
           "Sintima Multi-Chnnel Support System",       /* Title Text */
           WS_OVERLAPPEDWINDOW, /* default window */
           CW_USEDEFAULT,       /* Windows decides the position */
           CW_USEDEFAULT,       /* where the window ends up on the screen */
           610,                 /* The programs width */
           400,                 /* and height in pixels */
           HWND_DESKTOP,        /* The window is a child-window to desktop */
           NULL,                /* No menu */
           hThisInstance,       /* Program Instance handler */
           NULL                 /* No Window Creation data */
           );

ich werds jetzt testen und dann die lösung hier posten.

WM_CHAR musst du abfangen dann ist der beep weg hier

LRESULT CALLBACK EditProc( HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam )
{
	switch(msg)
	{
		case WM_CHAR:
		case WM_KEYDOWN:
			if( wParam == VK_RETURN )
				return 0;
		break;
	}

	return CallWindowProc( oldEditProc, hWnd, msg, wParam, lParam );
}

das problem ist jetzt, das ich in das Edit net schreiben kann

jop dann machste was falsch

LRESULT CALLBACK MsgControl (HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    char text[255]; //text von hMsg
    char txt[255];
    switch(msg)
    {
        case WM_CHAR:
        case WM_KEYDOWN:
            if (wParam == VK_RETURN)
            {
                SendMessage(hMsg, WM_GETTEXT, sizeof(text), (ULONG)text);
                SendMessage(hChat, WM_GETTEXT, sizeof(txt), (ULONG)txt);
                send_msg(text, txt);
                return 0;
            }
            break;
        default :
            return CallWindowProc ((WNDPROC) PrevhMsg, hwnd, msg, wParam, lParam);  
    }
    return 0;
}

is das calback
