Let me get this straight. What you want is that your main dialog is created, and IF your login dialog is closed with OK, you want your main dialog to appear on screen, but if it is closed with CANCEL you want your main dialog to still exist BUT not be shown on the screen?

You can call EndDialog() and return immediately from OnInitDialog(), instead of calling exit()

Are you sure that you are getting the IDCANCEL when you click the cancel button? And how/where are you creating the main dialog and the login dialog? I wonder how the main dialog exists after calling the EndDialog... most probably it is not getting called.

Try to put a break point at the if( loginDlg.DoModal()... statement and check control flow.

If it is not going to the EndDialog statement, then check the login dialog code. If you are using the default cancel of the dialog then IDCANCEL will be the return value of the DoModal.

Actually I made the mistake... I misunderstood your words. Really sorry. Cry | :((

So I hope you just need to keep the main application running after closing the login dialog. Am I right?

If this is the case that you need, then you must not call the EndDialog. Then do you need to hide the main dialog? Could you please rephrase your need?

What you need to do? You just want to bring it to minimized or hidden state?

For one, LoadDlg.cpp and SettingDlg.cpp are source files (i assume), not classes. And for two, that mostly depends on the context, you could for example give the value you set in your loaderdlg as a parameter to the setting dialog class's constructor, or store it in a global variable, or or or...

Well, either give that value to your setting dlg as a parameter thorough its constructor (and store it in your setting dialog class as a member), or give a pointer to your loader dialog the same way and when you need the variable, use the pointer to access the value. Or if you need that variable after your setting window has been created, you can also try calling GetParent() in your setting dialog, convert what you get to the class of your load dialog and then access the meber as you must. But this later method is a bit ugly (what if you want to display your setting dialog from somewhere else os its parent won't be something else than your load dialog?).
