RE: How to display a PrintPreview window not the called view?

Hi Rider,

>How to display a PrintPreview window not the called view?

For example, when the CView1's window is active, you select the Print
Preview in the menu, then the CView2's Print Preview dialog will be
displayed:

To achieve this, you can definite a globle CView pointer, reference it to
the CView2's object in CView2's constructor:
//in yourApp.cpp
CView* g_pSecondView;

//in View2.cpp
extern CView* g_pSecondView;
CView2::CView2()
{
g_pSecondView = this;
}


Then in CView1::OnFilePrintPreview() function calls the
CView2::OnFilePrintPreview() instead:
//in View1.cpp
extern CView* g_pSecondView;
void CView1::OnFilePrintPreview()
{
if(g_pSecondView)
((CView2*)g_pSecondView)->OnFilePrintPreview();
else
CBaseView::OnFilePrintPreview();
}


Wish it helps!
