back,next and cancel

What you want is called a "Wizard."  MFC supports this a a special case of what is called a CPropertySheet.  Real all about it:

and

In particular, you will need to call SetWizardMode() before calling DoModal();

Hi Shielsey
I looked at you answer it is fine if i am using just  3 or 4 dialogs but my apllication has 10 dialogs. You can view my apllication to be somewhat similar to those dialogs when ur installing an application.First of it has a splash screen then it asks the user to select options and later it stores the opetions in a drive an d somethinglike  that.'
Thank you if can suggest a remedy for this case.
but anyway i will try to use the one proposed by you.i am not sure of using base calss .so i will try to  use it thank you.

You should use a Wizard-style PropertySheet.  It is designed to do *exactly* what you want to do.  Did you read my post?  Do you need additional details?

Dan,
can youplease give me those aditonal details  . iam a new bie i do n ot know anything about property sheet and also i wnat to ask how to close all dialogs when you clickk on X
button.'
thaank you

It really is quite simple.  Please read:

  http://msdn.microsoft.com/library/en-us/vccore98/HTML/_core_property_sheets.asp

which explains it in detail and provides examples.  It boils down to...

CDlgPgWelcome pgWelcome; // a dlg box, but derived from CPropertyPage
CDlgPgStep1   pgStep1;  // also
CDlgPgStep2   pgStep2;  // also

CPropertySheet cSheet("ABC Install Wizard");

cSheet.AddPage( &pgWelcome );
cSheet.AddPage( &pgStep1 );
cSheet.AddPage( &pgStep2 );
cSheet.SetWizardMode();

int nRet= cSheet.DoModal();
if (nRet== IDOK ) {
   the user did not cancel from the wizard
   ...etc...
}

This is a 50-point question that has already been locked, so I expect you to do a bit of research on your own.

Thank you Dan and Shielsy

The pleasure is all mine.  I guess.
