打印页面设置问题?做过的帮忙啊!!!!!!!在线等..............

[qqhrdi1]

在打印页面设置CPageSetupDialog中有m_psd成员,在构造CPageSetupDialog对象后,可以用它设置不同外形的对话框,之后用DoModal()显示，在m_psd中PtPaperSize可以设置纸张大小，我想将打印机的默认纸张改为＂宽行打印纸＂，如何设置？（使打印页面设置对话框打开后的纸张默认是＂宽行打印纸＂）另外宽行打印纸和B5纸的宏定义字符串是什么？

定义一个DEVMODE* defdeviceset;
　　defdeviceset=(DEVMODE*)malloc(sizeof(DEVMODE));
　　defdeviceset->dmPaperSize=DMPAPER_B5;
//打印
void CNetRepControlCtrl::OnPrint()
{
// TODO: Add your command handler code here
//CPrintDialog dlg(FALSE, PD_ALLPAGES | PD_COLLATE | PD_NOPAGENUMS | PD_HIDEPRINTTOFILE);
//CPrintDialog dlg(FALSE);
CPrintDialog dlg(FALSE, PD_SELECTION | PD_USEDEVMODECOPIES);
if(defdeviceset!=NULL)
dlg.m_pd.hDevMode=defdeviceset;
dlg.m_pd.nCopies=1;
dlg.m_pd.nMaxPage=PageCount;
dlg.m_pd.nMinPage=1;
dlg.m_pd.nFromPage=1;
dlg.m_pd.nToPage=PageCount;
if(dlg.DoModal()==IDOK)
{
int nBeginPage,nEndPage;
if (dlg.PrintAll()) // print all pages in the document
{
nBeginPage = dlg.m_pd.nMinPage;
nEndPage = dlg.m_pd.nMaxPage;
}
else if (dlg.PrintRange()) // print only a range of pages
{ // in the document
nBeginPage = dlg.GetFromPage();
nEndPage = dlg.GetToPage();
}
else if (dlg.PrintSelection()) // print only the currently selected
{
nBeginPage = nEndPage = nNowPagePos; // -1 to denote unknown yet
}


HDC hdc = dlg.GetPrinterDC();
CDC* pDC=new CDC();
pDC->Attach(hdc);

PreParePrinter(pDC);
PrintTabPage(pDC,nBeginPage,nEndPage);
// PrintRepTab(pDC);

pDC->Detach();

delete pDC;
}
}
//准备打印机上下文
void CNetRepControlCtrl::PreParePrinter(CDC* pDC)
{
pDC->SetMapMode(MM_ANISOTROPIC);
//转换坐标映射方式
CSize size = CSize(PageWidth, PageHeight);
pDC->SetWindowExt(size);//确定窗口大小
/*
//得到实际设备每逻辑英寸的像素数量
int xLogPixPerInch = pDC->GetDeviceCaps(LOGPIXELSX);
int yLogPixPerInch = pDC->GetDeviceCaps(LOGPIXELSY);

//得到设备坐标和逻辑坐标的比例
long xExt = (long)size.cx * xLogPixPerInch/96;
long yExt = (long)size.cy * yLogPixPerInch/96;
pDC->SetViewportExt((int)xExt, (int)yExt);
*/
int xExt=pDC->GetDeviceCaps(HORZRES);
int yExt=pDC->GetDeviceCaps(VERTRES);
pDC->SetViewportExt(xExt,yExt);
}

我的问题是如何修改默认设置指张问题!!!!!!!!!!

[bluebohe]

改动默认纸张的话相应改动pDevMode->dmPaperSize

/* 设置系统打印模式
#define DMORIENT_PORTRAIT 1 //纵向
#define DMORIENT_LANDSCAPE 2 //横向 */
/************************************************************************/

void SetLandscapeMode(int PrintMode)
{
PRINTDLG pd;
pd.lStructSize=(DWORD)sizeof(PRINTDLG);
BOOL bRet=AfxGetApp()->GetPrinterDeviceDefaults(&pd);
if(bRet)
{
// protect memory handle with ::GlobalLock and ::GlobalUnlock
DEVMODE FAR *pDevMode=(DEVMODE FAR *)::GlobalLock(pd.hDevMode);
// set orientation to landscape
if(PrintMode==1)//纵向打印
pDevMode->dmOrientation=DMORIENT_PORTRAIT;
else if(PrintMode==2)//横向打印
pDevMode->dmOrientation=DMORIENT_LANDSCAPE;
::GlobalUnlock(pd.hDevMode);
}
}
纸张定义参见MSDN，太长了放不下

DEVMODE* defdeviceset;
　　defdeviceset=(DEVMODE*)malloc(sizeof(DEVMODE));
　　defdeviceset->dmPaperSize=DMPAPER_B5; //纸张的设定
