how can I auto-validate a dialog after it displays?

[davidewan]

Hi all,

I've got a dialog. when it displays, I want to check the info loaded and warn the user if some of the data is bad (e.g. invalid directory). Doing this check while the dialog is constructing results in the error message popping up first, then the dialog (after the uer acknowledges the error) which is kind of dumb. What I really want is the dialog to appear and then the error messages. One solution I've thought of is to send a home grown message to myself ostMessage()) during OnInitDialog(). I'm just wondering if there's a neater way? Thanks in advance. David. [sig][/sig]

in OnInitDialog:

SetTimer( 1 , 100 , NULL );

Add WM_TIMER and then:

void CYourDlg::OnTimer(UINT nIDEvent)
{
if ( nIDEvent == 1 )
{
KillTimer( 1 );
AfxMessageBox( ........... );
}

CDialog::OnTimer(nIDEvent);
}
