landscape print in dialog?

[JockeP]

Is there a way to change the print page orientation to landscape in a dialog mode, i e I'm not using Document- View mode? To print I've previously used ShellExecute method.

Look this code:

PRINTDLG pd;
pd.lStructSize=(DWORD)sizeof(PRINTDLG);
if(AfxGetApp()->GetPrinterDeviceDefaults(&pd))
{
// protect memory handle with ::GlobalLock and ::GlobalUnlock
DEVMODE FAR *lpDevMode=(DEVMODE FAR *)::GlobalLock(pd.hDevMode);
lpDevMode->dmOrientation = (short)(bLandscape) ? ORIENT_LANDSCAPE : DMORIENT_PORTRAIT);
pDC->ResetDC(lpDevMode);
::GlobalUnlock(pd.hDevMode);
}

Best regards, Eugene Pustovoyt

Thanks, but I get these five errors when compiling: error C2065: 'bLandscape' : undeclared identifier error C2065: 'ORIENT_LANDSCAPE' : undeclared identifier error C2059: syntax error : ')' error C2065: 'pDC' : undeclared identifier error C2227: left of '->ResetDCA' must point to class/struct/union Generating Code... Error executing cl.exe. It seems bLandscape does not exist. Where does that variable come from? I can also not find ORIENT_LANDSCAPE in MSDN.

I can't write a code for yours. Just it is a sample of the code and not realy code. bLanscape is a variable which specified what you want orient. TRUE - LANSCAPE, FALSE - PORTRAIT.:( DMORIENT_LANDSCAPE is constant for DEVMODE strucrure. Therefore, you must look in MSDN DEVMODE structure and not constants. pDC is a pointer to your context of the printer. Best regards, Eugene Pustovoyt

Thanks for your reply Eugene! However, I'm sorry I still dont get it. I'm not using Document-View mode in which I think I know how to retreive the Device Context (pDC). I'm using Dialog mode. How can you acheive this? I also noticed you converted bLandscape to short. Why? Isn't it only the value that's assignmed dmOrientation that needs to be short?! Finally, does this alter the settings of my default printer straight away without showing any dialog, or what happens? Thanks again, Joachim
