Please help on refreshing dialog after error
OK, i hope this will be more clear:
I call my mainprogram function (where the data file is tested for existence and
other calculations are performed), from the OnOK() function
void CDialog1Dlg::OnOK()
{
mainprogram(); //Calls the function mainprogram When this process ends, the
estimator finishes.
CDialog::OnOK();
MessageBox("The Estimator has finished.", "Simulation Finished", MB_OK |
MB_ICONINFORMATION);
Quote:
}
The check for the data file is in the main program as shown below:
if (!datafile.is_open())
{
MessageBox("The file was not opened.\n Please retry", "Error message",
MB_OK | MB_ICONINFORMATION);
}
So, i guess one solution would be to take it above before mainprogram is even called
but i prefer to have it in the main program since that is the place from where i
read the data from the file.
Do you have any suggestions on that? Can you show me some code as well so that i
will be sure i don't{*filter*}up?
Thanks,
Elias
