how do i share a variable that is declared in the dialog class, with my cview class.  I need to do this because the variable is a member variable for a group of radio buttons in my dialog class.  Thanks

If you create your dialog with DoModal() try this

CYourDialog dlg;
if(dlg.DoModal()==IDOK)
{
     m_viewvairable = dlg.m_dialogvariable;
}

The easiest thing is to make a global variable in you CView class .CPP file and use an extern in the dialog class .CPP file and place the value of the member variable in the shared variable. Example (which uses and int variable):

In CVIEW.CPP:

int ExampleVariable; // place at the top of the file under preprocessor definitions/#includes etc.


In DIALOG.CPP:

extern int ExampleVariable;// place at the top of the file under preprocessor definitions/#includes etc.
.
void DIALOGCLASS::SomeFunction ()
{
ExampleVariable = m_nMemberVariable; // m_nMemberVariable is a member variable of the DIALOGCLASS

}
