When the printer is connect, there is no problem I print normally but when the printer is disconnect this error appear.

My problem is that I want to avoid this error what to do?

I try without success this
if (!dc.Attach(printdlg.GetPrinterDC()))
return

How do you use CPrintDialog

This want I write:
CPrintDialog printdlg(true, dwFlags,pParent);

printdlg.GetDefaults();

DEVMODE *MyPrintMode;
MyPrintMode = NULL;
MyPrintMode = printdlg.GetDevMode();
dc.CreateDC(printdlg.GetDriverName(), // Ignored for Printer DC's
printdlg.GetDeviceName(), // The only required item for Printer DC's
printdlg.GetPortName(), // Ignored for Printer DC's
MyPrintMode);

dc.Attach(printdlg.GetPrinterDC());

The error arise on the last sentence

I learn My self

if you use this code you get error

<br />
	CPrintDialog printdlg(false);<br />
printdlg.GetDefaults();<br />
<br />
CDC dc22;<br />
DEVMODE *MyPrintMode;<br />
MyPrintMode = NULL;<br />
MyPrintMode = printdlg.GetDevMode();<br />
//dc22.CreateDC(printdlg.GetDriverName(), // Ignored for Printer DC's<br />
//printdlg.GetDeviceName(), // The only required item for Printer DC's<br />
//printdlg.GetPortName(), // Ignored for Printer DC's<br />
//MyPrintMode); <br />
HDC hdc=printdlg.GetPrinterDC();<br />
dc22.Attach(printdlg.GetPrinterDC()); <br />
<br />

Thanks for your assistance.

Dear Sir,

When I write this
DWORD dwFlags = PD_PAGENUMS ;

CWnd *pParent = this;

CPrintDialog printdlg(false, dwFlags,pParent);

Why pages is not enabled on the printing dialog that appears.

How do you send your pages to printer?

DWORD dwFlags = PD_PAGENUMS;
CWnd *pParent = this;

CPrintDialog printdlg(false, dwFlags,pParent);

if(printdlg.DoModal() == IDCANCEL)
return;

DEVMODE *MyPrintMode;
MyPrintMode = NULL;
MyPrintMode = printdlg.GetDevMode();
dc.Attach(printdlg.GetPrinterDC());

Why you dont use from PrintDlg(&pd); and use from pd.hDC

Please Sir, I don't understand you.
I learn My self , show me what to do.

Perhaps I don't know well what I am doing.

Would you like to correct my codes that I show you?

Hamid_RT28-Jul-06 8:02

I said you can use from PrintDlg(&pd); like this

	PRINTDLG	pd;
	DOCINFO		di;
      memset((void *)&pd, 0,sizeof(PRINTDLG));
      pd.lStructSize = sizeof(PRINTDLG);
      pd.hwndOwner   = m_hWnd;
      pd.Flags =PD_RETURNDC|PD_ENABLESETUPTEMPLATE;
      pd.hInstance   = NULL;
	  pd.nMaxPage=1;
	  pd.nMinPage=1;
	  pd.nCopies=1;
	  pd.hDevMode=0;
	  pd.nFromPage=1;
	  pd.nToPage=1;
	PrintDlg(&pd);

  di.cbSize      = sizeof(DOCINFO);
  di.lpszDocName = "Test";
  di.lpszOutput  = NULL;

StartDoc(pd.hDC, &di);
CImage m_Image;//you must include atlimage.h
m_Image.Load("c:\\0.bmp");
m_Image.BitBlt(pd.hDC,0,0,800,600,0,0,SRCCOPY);
EndDoc(pd.hDC);

No thing changed, Pages is dimmed again and initialise to 1 to 1.

I like that pages not dimmed and I can choose my self from what page to what pages to print like we do on Word or Excel

Hamid_RT28-Jul-06 22:09

28-Jul-06 22:09

I didnt see this problem and you can print these pages or not

Pages to print is not fixed in the program codes.
I need when Printing dialog appears, i choice my self from 3 to 5 for example. Hence In the dialog that appears there is not this possibility to change because it's dimmed.
That's my problem

Hamid_RT28-Jul-06 22:41

28-Jul-06 22:41

if you test my previous example you can see that i choose
pd.nFromPage=1; pd.nToPage=1;and it work do you test this code

I test it, I see that on printing dialog there is : pages from 1 to 1. And pages is dimmed. No means to change, that's my problem. Why is it dimmed, so there is no mean to change(for example from 1 to 2)
