Multi Dialogs, wizard type application issue and non-repeatitive problem

Asked by Develprog in Microsoft Visual C++, Windows MFC Programming, C++ Programming Language

Hi,
First of all the application had 1 dialog, this is an user interface
application that the purpose is to configure a device and NIC cards
step by step with parameters that the user decide. CIPSetupDlg

To be more usefull, it must have 3 Dialogs: Dlg_1, Dlg_2, Dlg_3.
The 3 Dialogs have Next and Preview button to step over through Dialogs
representing so three steps (step1, step2, step3) like a Wizard program.

So I had 3 Dialogs and decided to redesign this application by hiding the main
Dialog (IP SetupDlg) and when application is launching the first Dialog that appears is Dlg_1 and so the user can push on next button till Dlg_3 which one contains the finish button.

The problem is that when I advance from Dlg_2 to Dlg_3 "sometimes" the Dlg_2 is not closing an it stays. So the user see Dlg_2 and Dlg_3 and it is perturbing because the step 2 (Dlg_2) is normally finished. The strange thing is that Dlg_2 appears SOMETIMES not always ??

So the functions I used to hide/show dialogs are: EndDialog(), DoModal() and ShowWindow(SW_HIDE)

So my question how can I close or Hide the Dlg_2 (if it appears) when the Dlg_3 is launching ?

Here you are my code for the 4 Dialogs. (Just one thing to know : Dlg_3 and Dlg_2 are switched , so Dlg_3 is the Step 2 and Dlg_2 is the last step Step 3)

Thank you
