I have an application in which I have an administrator dialog. With
the administrator dialog (dialog B). I want to set a variable in
another dialog (dialog C). However, (dialog C) does not open (ie
DoModal() ) from (Dialog B), but rather from another dialog class
(Dialog A) How can I get (dialog B) to change a variable in (dialog
C)? Would I use a Global variable? or perhaps write the variable to
the registry? Or is there an other better way?

Thanks in advance,
