 Refreshing dialog Dear friends, I have a check if a data file is opened as shown in the code below. It
works ok, but my problem is that afterwards, instead of staying in the
same dialog and allow me to enter another data file, it proceeds to the
next dialog. How can i refresh the same dialog for a second chance to
enter another file?
if (!datafile.is_open()) //checks to see if file opens successfully
{
MessageBox("The file was not opened.\n Please retry", "Error message",
MB_OK | MB_ICONINFORMATION);
}
Thanks,
Elias

What dialog are you using? Where is your handler for checking the validity of file? --

Refreshing dialog Here is how i call my dialog: void CDialog1Dlg::OnBrowse() { CFileDialog dlg( true, NULL, NULL, OFN_HIDEREADONLY, _T("Text files (.txt)|*.txt|") _T("|") ); if (IDOK!=dlg.DoModal()) return; m_FileNameFull = dlg.GetPathName(); m_filename = dlg.GetFileName(); UpdateData(false); UpdateOKUI(); Quote: }
I hope this makes more sense, Elias Quote:

Refreshing dialog Hi Elias! Can't find your file check in the new code...
Need both to help you...
If you check after the "dlg.DoModal()" the file dialog is already closed...
ciao

Refreshing dialog What do you mean by file check? What should i look for? Quote:

Refreshing dialog Why use UpdateData (which I consider really harmful). Instead, create a control-type variable for whatever controls and call SetWindowText. See my essays on dialog control management, avoiding UpdateData, and avoiding GetDlgItem on my MVP Tips site. What I don't understand here is where your test about the file open was done, and what the consequence of doing it was. All I see in your previous message is a statement that issues an error message, and all I see in this example is a fairly normal file dialog being invoked in the context of another dialog. How are the two examples connected? joe On Mon, 26 Feb 2001 21:40:05 -0700, Elias Kyriakides

Refreshing dialog 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

Refreshing dialog Well, you say that if you get the message about the file not found you don't want to exit the dialog. Yet the code you showed clearly does this! For example, if you did if(!mainprogram())
return;
and made mainprogram() a BOOL-returning function that returned FALSE
if the file was not found, your problem would go away.
