How do I set which radio button is selected when I DoModal() the dialog they are in? Presently the wrong one is selected. I think I once knew, but I no longer remember.

There's a couple of ways, most straight forward is...

CMyDialog::OnInitDialog()
{
  CDialog::OnInitDialog();
  CButton *button = GetDlgItem( nID ); //nID is resource ID
  button->SetCheck( BST_UNCHECKED );   //Or BST_CHECKED
}

Tnx, that solves my problem. But I'm puzzled as to what sets the default if I don't do it explicitly. Is it the order in the resource file?

You should set your own defaults in the OnInitDialog() call... if there's a variable that's linked using the DDX_Control functions, than the default loaded will be whatever that variable indicates...

Thank you, I think I'm getting it (I wrote a lot of Windows in C++ before 2000, but since then I've been stuck in VB, and retreading my brain is painful).

I know the feeling... I forget a lot of things I've learned over the years... good luck!
