Printable View
Hi
I have a SDI application with a CListView. I have a menu option which call the function OnFilePrintPreview(). In this moment the application fails...
I have use this code before and it works fine. Since then I change my version of Visual C++.Code:void CVisionCARView::TiparesteAcordImprumut(void)
{
AfxMessageBox("Tipareste");
OnFilePrintPreview();
}
It posible to be a bug?
I'm using now Visual C++ 2003 Standard.
Fails? What exactly is happening?Quote:

sulu
The message is:
Debug Assertion Failed!
Program: ...
File: bardlg.cpp
Line: 44
And in OUTPUT window I Have:
ERROR: Cannot find dialog template with IDD 0x7803.
Unhandled exception at 0x005c4afa in VisionCAR.exe: User breakpoint.
I haven't override the function OnFilePrintPreview.
So an assertion failed. And - have you looked at line 44 of bardlg.cpp to see which assertion failed?Quote:

PostNcDestroy(); // cleanup if Create fails too soon
return FALSE;
}
#endif //_DEBUG
I try the same code in Visual C++ 2002 and I have the same problem. I think that I'm doing something wrong but I don't understand what... :confused:
Please make this simple test and tell me if it working at you.
Make a SDI application with a view of type CListView.
If I make an SDI application with a view of type CView it works very well.
Please help me... :confused:
Well, it tells you why it fails: A dialog resource template (probably the one used for the print preview dialog bar) could not be found - they are located in afxprint.rc.Quote:

Printing and print preview is not automatically supported for control-based views like CListView.
I shoul edit some code for that? Do you know an example?
anybody?
The easiest way is to create a new project and select CView as the view type - and add your CControlView later. However, you will still need to implement the printing code yourself.Quote:

#pragma code_page(1252)
#endif //_WIN32
#include "res\YourApplicationName.rc2" // non-Microsoft Visual C++ edited resources
#include "afxres.rc" // Standard components
#include "afxprint.rc" // printing/print preview resources
#endif
Yes - but that alone won't help: You still need to implement OnPreparePrinting() and OnPrint(), (and possibly also OnBeginPrinting() and OnEndPrinting()) in the view class, and call at least DoPreparePrinting() in the OnPreparePrinting() implementation - or the call to OnFilePrintPreview() will assert at another point.Quote:

I have include
#include "afxprint.rc" // printing/print preview resources
into resources file and implement OnPreparePrinting() and OnPrint(), OnBeginPrinting() and OnEndPrinting()) in the view class, and call DoPreparePrinting() in the OnPreparePrinting() implementation.
I have included also into the resources file:
(accelerator)
"P", ID_FILE_PRINT, VIRTKEY,CONTROL
(into string table)
ID_FILE_PAGE_SETUP "Change the printing options\nPage Setup"
ID_FILE_PRINT_SETUP "Change the printer and printing options\nPrint Setup"
ID_FILE_PRINT "Print the active document\nPrint"
ID_FILE_PRINT_PREVIEW "Display full pages\nPrint Preview"
Code:void CVisionCARView::OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo)
{
// TODO: Add your specialized code here and/or call the base class
pInfo->SetMinPage(1);
pInfo->SetMaxPage(1);
//CListView::OnBeginPrinting(pDC, pInfo);
}
void CVisionCARView::OnEndPrinting(CDC* pDC, CPrintInfo* pInfo)
{
// TODO: Add your specialized code here and/or call the base class
//CListView::OnEndPrinting(pDC, pInfo);
}
BOOL CVisionCARView::OnPreparePrinting(CPrintInfo* pInfo)
{
// TODO: call DoPreparePrinting to invoke the Print dialog box
if(tiparesteComanda)
{
pInfo->SetMinPage(1);
pInfo->m_bDirect = TRUE; //don't show the printer settings }
pInfo->m_strPageDesc = "Page %u\nPages %u-%u\n";
PRINTDLG pd;
pd = pInfo->m_pPD->m_pd;
pd.lStructSize=(DWORD)sizeof(PRINTDLG);
BOOL bRet = theApp.GetPrinterDeviceDefaults(&pd);
if(bRet)
{
// protect memory handle with ::GlobalLock and ::GlobalUnlock
DEVMODE FAR *pDevMode=(DEVMODE FAR *)::GlobalLock(pd.hDevMode);
pDevMode->dmOrientation = DMORIENT_PORTRAIT;
// set orientation
if(tiparesteComanda)
{
pDevMode->dmOrientation = DMORIENT_PORTRAIT;
}
else
if((tipVedere == 1) || (tipVedere == 3))
{
pDevMode->dmOrientation = DMORIENT_LANDSCAPE;
}
else
if(tipVedere == 2)
{
pDevMode->dmOrientation = DMORIENT_PORTRAIT;
}
else
{
pDevMode->dmOrientation = DMORIENT_PORTRAIT;
}
::GlobalUnlock(pd.hDevMode);
}
return DoPreparePrinting(pInfo);
//return CListView::OnPreparePrinting(pInfo);
}
void CVisionCARView::OnPrint(CDC* pDC, CPrintInfo* pInfo)
{
// TODO: Add your specialized code here and/or call the base class
CPen penBlack(0, 1, RGB(200, 0, 0));
CPen* pOldPen = pDC->SelectObject(&penBlack);
pDC->MoveTo(0 ,0);
pDC->LineTo(300, 300);
pDC->SelectObject(pOldPen);
//CListView::OnPrint(pDC, pInfo);
}
It working now. Thanks. :) :) :)
