Hi

I sent the following email

We failed to compile your project. The following "include" is not found in the StdAfx.h file:

#include <BaseTsdEx.h>

The following "include"s are not found in the ChildView.h, MuPrintGridPrPage.h and MuPrintGrid.h files:

#include "MTBASE\MtTempl.h"
#include "MTBASE\MtDefine.h"

As a result, many things like DECLARE_SMART_PTR cannot be compiled.

Hi

Because I revised a program, please try to test it with a thing of this place.

We compiled and run your test project successfully. The dialog with a grid in print preview mode becomes displayed over the main frame window and occupies the same position on the desktop. But the real problem is that these both dialogs are children (descendent) of the main frame window and you are trying to let both of them to run the modal message loop. You should destroy the first dialog before displaying the dialog with the grid window in the print preview mode. Please update the source code for the following method:

void Dialog2::OnOK() 
{
      CDialog::OnOK();
      m_PrtPreviewDlg = new CPrtPreviewDlg ;
      m_PrtPreviewDlg->Create ( CPrtPreviewDlg::IDD , ::AfxGetMainWnd() );
      m_PrtPreviewDlg->GoPrint( 0 );
}

Hello

I do not want to destroy Dialog2(Print setting dialogue).
Is not there another technique?

If you don’t want to destroy it, you should hide it before displaying the print-preview dialog and show it when the print preview dialog is closed. This is completely possible because the print preview dialog is modal.
