Return Value

Type: Usual
A pointer to the DevMode structure or 0 if the structure is inaccessible. You should store this pointer in a variable typed "AS _WINDEVMODE".
Remarks
The DevMode structure is documented in the Win32 SDK and is defined in the X# Win32 API Library. This structure resides in the underlying PrintingDevice object and is created by using the device driver associated with the object. Updates to members of this structure are applied via the PrintingDevice:UpdateDevMode() method.
Examples
This example accesses and displays various information from the DevMode structure:
