I have a customized CFileDialog (e.g. CCustFileDialog) with a child dialog template. Everything is working fine except that now I want the default button change to one of the button in my child template (e.g. IDOK1).

Here is the code I tried but failed:

void CCustFileDialog::OnInitDone()
{
     // Set default button

     GetParent()->SetDefID(IDOK1);
     ((CButton*)GetParent()->GetDlgItem(IDOK))->SetButtonStyle(BS_PUSHBUTTON);
     SendDlgItemMessage(IDOK1, BM_SETSTYLE, BS_DEFPUSHBUTTON, MAKELPARAM(TRUE, 0));
}

Any one can help?

Try sending a DM_SETDEFID message as well.

Well if you look at DevStudio\VC\mfc\include\AFXWIN2.INL(570):

_AFXWIN_INLINE void CDialog::SetDefID(UINT nID)
      { ASSERT(::IsWindow(m_hWnd)); ::SendMessage(m_hWnd, DM_SETDEFID, nID, 0); }

The call of SetDefID() is sending a DM_SETDEFID....

Try to open WinZip with an existing file and Add. You can see that it is using the CFileDialog with some buttons underneath. If you press enter on some of them, you got nothing.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Is CCustFileDialog derived from CFileDialog? Why do you use GetParent()?

It should be

void CCustFileDialog::OnInitDone()
{
     // Set default button

     this->SetDefID(IDOK1);
}

If this still does not work, try the following:

1. Define a user-defined message;
2. Post the user-defined message in CCustFileDialog::OnInitDone() by using this->PostMessage;
3. When CCustFileDialog receives this message, call this->SetDefID(IDOK1);.

No luck with this->SetDefID() and the PostMessage() also.

The way to set the default button to a child dialog is not mentioned clearly in the documentation.

How about setting the Default Button style in the Dialog Editor?

Set the flag "OFN_EXPLORER" for your CFileDialog derived class..
