global variables

[shwetashah01]

How do I create global variable for dialog class (global object of dialog class), which is accessible to all other classes including other dialog classes?

[Skizmo]

Put the variable in the public section.

but public section of which class or file?

Did you mean "global" or static variable for dialog class?
If former - then why?

[shwetashah01]

I need global variables or objects of dialog class for eg:- if my dialog class is dlg1 then I need the object as dlg1 d1 globally so that i can directly access d1 in other dialog classes such as dlg2, dlg3 etc.

[VictorN]

Do you mean the "dialog classes" or " dialog class instances"?

[shwetashah01]

dlg1, dlg2 etc. are the names given to dialogbox class & d1,d2... are the instances of dlg1,dlg2...
& I want to declare d1,d2 globally

2. Usually declaring globals is not a good idea. In the most of cases (at least 99.99%) globals can be and should be avoided.
What is the purpose to access dlg1 d1 from within other dialog classes such as dlg2, dlg3 etc.?

I want to show dlg1 dialog from dlg2 & dlg3 on button
click

I want to show dlg1 dialog from dlg2 & dlg3 on button

So why do you need a global variable for this? Just declare one locally and call DoModal().

dlg2::OnOk()
{
    dlg1 myDlg;
    myDlg.DoModal();
   // ....
}

Given your description, I see no need for global variables whatsoever if all you want to do is invoke a dialog from another dialog.
