(WINAPI) I need help with WM_KILLFOCUS

[Nobody/Anonymous]

I have posted a question last week asking for a way to disable Keybord and Mouse input on controls without using EnableWindow(HWND, FALSE) because that makes them grayed, which makes it hard to read its content.

A guy answered that a good way would be to intercept the FOCUS messages and direct the focus elsewhere.

I thought that would be a great solution, but as a beginner, i couldnt code something 100% functional.

Heres what i have right now. The problem with this piece of code is kindda weird: It works only once, i mean, if you click over one of the controls, it does not receives the focus: the focus is sent to buttonstart. Then if you click over any control, it receives the focus. My question is: Why the hell would this code work only for the first click?

Any help would be appreciated.

case WM_KILLFOCUS:
        if (((LOWORD(wParam))==IDC_CLEARBUTTON) || /* This are the controls that can receive focus */
           ((LOWORD(wParam))==IDC_CHECKSCROLL) ||
           ((LOWORD(wParam))==IDC_COPYBUTTON) ||
           ((LOWORD(wParam))==IDC_BUTTONSTART) ||
           ((LOWORD(wParam))==IDC_BUTTONSTOP) ||
           ((LOWORD(wParam))==IDC_BUTTONVIEWLOG) ||
           ((LOWORD(wParam))==IDC_BUTTONABOUT)) {
          return DefWindowProc (mainWindow, messages, wParam, lParam);
          return 0;
        }
        else { /* For the controls that cannot receive focus */
          SetFocus(buttonstart); /*Lets set the focus elsewhere */
          return 0;
        }

Hmm, are you capturing the focus and not releasing it somehow on the other controls? If you wish to have your control accessible through tab key, simple us WS_TABSTOP in its style in the dialog resource (I am assuming you are doing it through that way).
