[Resolved] MFC: Show Dialog?

I'm showing a dialog via this code:

Code:

---

BOOL CListworkApp::InitInstance() {
    CListworkDlg dlg;
    m_pMainWnd = &dlg;
    int nResponse = dlg.DoModal();

    if (nResponse == IDOK) {

    } else if (nResponse == IDCANCEL) {

    }

    return FALSE;
}

---

Which is the default code provided by the wizard. However, when I remove the buttons and the code, the app disappears when enter is pressed.

I'm assuming there's another method to show the dialog so that this doesn't happen?

I'm guessing I have to use the Create() method, but I can't get it working. :confused:

Okay, now this works:

Code:

---

BOOL CWorkApp::InitInstance() {

    #ifdef _AFXDLL
        Enable3dControls();
    #else
        Enable3dControlsStatic();
    #endif


    CWorkDlg dlg;

    BOOL ret = dlg.Create(IDD_WORK_DIALOG,NULL);
    dlg.ShowWindow(SW_SHOW);
   
    return FALSE;
}

---

But the dialog box disappears right away. How do I fix that?

Even if you had removed the ok button and its code, the default code called, when enter key is pressed, is still OnOk().

1 solution is to change the default button, using SetDefID(); in the Initdialog() handler.

example,

SetDefID(ID_MY_OTHER_BUTTON);

SetDefID() is a member function of CDialog. Look it up in the MSDN for more details.

P.S. I don't know how well it works in a modeless dialog, I had only used it in modal dialog.

But you want to go back to the modal dialog anyway (DoModal())

I do? :confused:

Yes, so that the dialog doesn't close again immediatly.

But there isn't a button on my dialog. I only want it to close when the X is clicked.

I'm not sure how to fix this...any help would be appreciated.

Either this

Code:

---

BOOL CYourDialog::PreTranslateMessage(MSG* pMsg)
{
  // TODO: Add your specialized code here and/or call the base class
  if((pMsg->message == WM_KEYDOWN) && (pMsg->wParam == VK_RETURN))
    return TRUE;
  return CDialog::PreTranslateMessage(pMsg);
}

---

or this

Code:

---

void CYourDialog::OnOK()
{
  // CDialog::OnOK();        <-- Disable this line
}

I don't have an OnOK() but the first one worked perfectly. Thanks, man.

Okay, maybe it doesn't work so well. When I use that code, then try to go to the ClassWizard for an object, I get this error:

Parsing error: Expected "afx_msg"
Input Line: BOOL CVGRTaxDlg::PreTranslateMessage(MSG* pMsg);

And then the ClassWizard doesn't work. :(

Nevermind. Mistake on my part. It also wanted virtual in the header file, too.

Thanks for your help.
