How to initialize a modal dialog ? (C++ / MFC)

I would like to fill some fields of my dialog when it's shown. Consequently, I would like to follow those steps:

  1. construct the dialog object
  2. call DoModal()
  3. initialize its fields

However, I can pass to the instruction following DoModal() only when the dialog is closed. Consequently, how can I initialize my dialog's fields?

I tried to override DoModal():

int MyDialog::DoModal()
{
    int a = CDialogEx::DoModal();
    InitDialog();

    return a;
}

but it's the same issue: InitDialog() is called when the dialog is closed...

Create the dialog object, than add OnInitDialog on your dialog, this method will calls before showing dialog (OnInitDialog msdn). Add variables to your dialog (int a;)

Call dailog:

CDialog dlg;
dlg.a = 10;
dlg.DoModal();
