BUG: CreateDC Does Not Thunk DEVMODE Structure Correctly

• Microsoft Win32s, versions 1.2 and 1.25

SYMPTOMS

Under Win32s version 1.2 and 1.25, when a Win32-based application displays a printer setup dialog box that calls PrintDlg with the PD_PRINTSETUP flag and the printing orientation is changed from Portrait to Landscape, the DEVMODE structure obtained from the PrintDlg call to CreateDC is passed and creates a printer DC. If the printer driver is a postscript driver, anything printed using this DC is still in Portrait mode.

CAUSE

The thunking layer for CreateDC does not thunk the DEVMODE structure for the postcript driver correctly.

RESOLUTION

To work around the problem, avoid calling CreateDC with a DEVMODE structure. Instead, directly create the pinter DC by calling PrintDlg with the PD_RETURNDC flag. Then change the printing orientation from within the print dialog box.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are reasearching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
