Re: MFC Desktop application, child window

Depends on how you want your child dialog to act.
If you need it to be modal then simply declare a variable of the dialogs
class type and call DoModal on it.
void CMyMainDlg::OnButtonClicked()
{
    CChildDialog Dlg;
    if (Dlg.DoModal() == IDOK)
    {
        m_Value = Dlg.GetValue();
    }
}
Doing this will allow the user to only interact with the child dialog until
the child dialog is dismissed.

if you need the child dialog to be modeless thing become a little more
complicate. You will need to declare the variable in your class so that you
can destroy the window at some point. And instead of DoModal you have to
call the dialogs Create method instead

void CMyDialog::OnButtonClicked()
{
    if (!m_ChildDialog.IsWindow())
    {
        m_ChildDialog.Create(CChildDialog::IDD,this);
    }
    m_ChildDialog.ShowWindow(SW_SHOW);
}

There are many examples of this on the internet. try looking for articles in
www.codeproject.com and www.codeguru.com
