Embeded dialog problem

Env:  VC4.1   NT4.0(build 1234)

I have a dialog based application that has dialogs inside dialogs.
I use DoModal to bring them up.  My problem is that when the third
dialog exists the first dialog becomes active.

Here is what happens:

1. Application starts : Dialog A
2. in A press a button to call:  B.DoModal();
3. in B press a button to call:  C.DoModal();
4. in C press OK to exit the dialog.
now Dialog A becomes active, which is not what i want.  I want A to wait until
B also exists.

How can I have dialogs inside dialogs where the control follows the hierarchy,
keeping in mind that in the above example B and C could be called from any
other dialog?

any suggestions welcome,
navid.

Make sure that the parent window of each dialog is correct. If the parent of
C is B, then windows is supposed to put the focus back there when C completes.

  Sounds like dialog C's parent is being set to your main application
window.  Try explicitly setting dialog B as C's parent.

  Sorry, I don't have a compiler available to try this with, so I don't know
if it will work.

It seems like the parent (or owner) of your dialogs are not being set 
correctly.  CWnd has a SetParent and a SetOwner method.  You should 
try setting that during initialization.

Ideally this should somehow be set before DoModal.  CDialog::Create 
will optionally take a CWND, so that's a good place to do it, as 
well.

There's a method called PreModal that is called by DoModal that 
returns the window handle that will be used as the parent.  
Unfortunately it's not virtual.

thanks,

Did you try:

	B.DoModal( this );    //  where this is a pointer to A
	C.DoModal( this );    //  where this is a pointer to B

Good luck!
