Hi Nenita, 

There are two parts to the answer.  The first is how to close a dialog 
when its clicked on:

This is done in the dialog class (dlgabout.cpp) in response to the 
WM_LBUTTONDOWN message.  Use class wizard to create the function 
OnLButtonDown.  

This then calls to CDialog::OnOK function to close the dialog.  I've 
assigned the variable m_bSplash in the constructor so this 
functionality can be switched off when the about dialog is opened from 
the help menu.

void CDlgAbout::OnLButtonDown(UINT nFlags, CPoint point)
{
   if (m_bSplash)
   {
	OnOK();
   }
   CDialog::OnLButtonDown(nFlags, point);
}

Closing the splash panel and opening the login dialog:  

The about dialog is opened as a modal dialog.  This means that the rest 
of the program stops until it has closed.  Next the login dialog is 
opened...

// nrdbpro.cpp

BOOL CNRDBApp::InitInstance()
{
   //...

   // Display about box 

	CDlgAbout dlg(TRUE);
	dlg.DoModal();

   //...

  // Display login dialog

   if (!Login())
   {
      return FALSE;
   }

//...
}
