As others have mentioned it would be bad to leave a modal dialog running
more than just until the OK button is pressed as it could be blocking other
windows. You could make this a modeless dialog and then use ShowWindow()
SW_HIDE and SW_SHOW to hide or show the dialog. They you never have to
destroy it until you are ready to not use it for the rest of the program
life (I.E., in OnClose() function in mainframe).

Hi,
I have a method calling to my dialog.
I'm calling to this method to show mt dialog is in the start (
InitInstance())
and in the OnCheckNow() option from the menu.
I want to display only one performance of this dialog.

I set CListViewDlg dlg as global var,
then in the method that create my dialog:

dlg.DestroyWindow();//?????
int nResponse = dlg.DoModal();

It's correct to DestroyWindow anyway??
it's working to me..but is it a correct way to do this?

Thanking you in anticipation!!!
