RichEdit - Print - Print page 2-3?????

[pbrama]

We have a RichEditCtrl that we need to print. We enabled PD_PAGENUMS so we could select the pages we want to print but not sure how to modify the standard code to actually print the specified pages. I know we can get it from the nFromPage & nToPage but not sure how to "process" those selections properly (I didn't write the print routine although it looks pretty verbatim to some samples on the net).

Here is the code we have. for our PRINT call....

---------------------------------------

BOOL RichEditCtrl:nPrint()
{
CDC ThePrintDC; //create a device context to use
CPrintDialog PrintDialog(FALSE,PD_ALLPAGES); //make a print dialog too
PrintDialog.m_pd.nMinPage=1;
PrintDialog.m_pd.nMaxPage=10;
if(PrintDialog.DoModal()==IDOK) //pressed the ok button on the print dialog?
{
ThePrintDC.Attach(PrintDialog.GetPrinterDC()); //if so get settings
}
else
return FALSE; //leave this procedure, before anything bad happens

DOCINFO di; //make a docinfo structure
::ZeroMemory(&di, sizeof(DOCINFO)); //need to be claer, so clear stuff from it
di.cbSize=sizeof(DOCINFO); //set size member
di.lpszDocName=psPrintTitle; //set doc name, was passed via another funtion
FORMATRANGE fr; //make a format range structure
::ZeroMemory(&fr, sizeof(FORMATRANGE)); //clear stuff from it
HDC hdc=ThePrintDC.GetSafeHdc(); //get handle to DC we are using
fr.hdc=hdc; //Set meber in FormatRange struct
fr.hdcTarget=hdc; //Set member in FormatRange struct
//This bit here will get all the dimentions of the printer setup
int nHorizRes = ThePrintDC.GetDeviceCaps(HORZRES), //width P in MM
nVertRes = ThePrintDC.GetDeviceCaps(VERTRES), //hight in raster lines
nLogPixelsX = ThePrintDC.GetDeviceCaps(LOGPIXELSX), //pixels per inch along x
nLogPixelsY = ThePrintDC.GetDeviceCaps(LOGPIXELSY); //pixels per inch along y
//set the printable area of printer in the FormatRange struct
fr.rcPage.left = 0; //these 2 mean top left
fr.rcPage.top = 0;
fr.rcPage.right = (nHorizRes/nLogPixelsX) * 1440; //these 2 mean bottom right
fr.rcPage.bottom = (nVertRes/nLogPixelsY) * 1440; //equation changes pixel to TWIPS
// Set up some margins all around. Make them one inch
//results vary on printers depending on setup
fr.rc.left = fr.rcPage.left + 1440; // 1440 TWIPS = 1 inch.
fr.rc.top = fr.rcPage.top + 1440;
fr.rc.right = fr.rcPage.right - 1440;
fr.rc.bottom = fr.rcPage.bottom - 1440;
//select all text for printing
fr.chrg.cpMin = 0;
fr.chrg.cpMax = -1; //-1 selects all
//get length of document, used for more than one page
long CharRange = GetTextLength();
int ErrorStatus=0;
//create cancel dialog
//Start Printing
//ThePrintDC.SetAbortProc(&AbortProc(hdc, )); //dont know how callbacks works yet

ThePrintDC.StartDoc(&di); //start printing document
do
{
ThePrintDC.StartPage(); //start the page
fr.chrg.cpMin = FormatRange( &fr, TRUE );//send text to DC, and record index
//of last fitting char
ThePrintDC.EndPage();//end this page
}
}while(fr.chrg.cpMin <= CharRange); //while there is stuff to print ot there
ThePrintDC.EndDoc();

return TRUE;
}

Thanks for any recommendations... this code is really pretty greek to me!!!

Please use "Code Tags"

It is difficult to read your code

Sorry, wasn't aware how to do that.....

Here is the fixed code:

BOOL RichEditCtrl:nPrint()
{
     CDC ThePrintDC;                                                        //create a device context to use
     CPrintDialog PrintDialog(FALSE,PD_ALLPAGES);         //make a print dialog too
     PrintDialog.m_pd.nMinPage=1;
     PrintDialog.m_pd.nMaxPage=10;
     if(PrintDialog.DoModal()==IDOK)                                //pressed the ok button
     {
           ThePrintDC.Attach(PrintDialog.GetPrinterDC());   //if so get settings
     }
     else
         return FALSE;
