Changing printer settings, DEVMODE And C#
Nick,
The IntPtr return is a generic integer which you can use to get access to a
platform-dependent handle or structure. Use the ToPointer() method to cast
it to a void *, then cast it to the DEVMODE structure pointer. If you use
Managed Extensions for C++, the structure is already defined for you in the
Platform SDK; in C#, you may have to create your own structure definition.
Since the returned structure is a feature of the Windows API, you'll need
to call Windows APIs using the pointer. You may find the article Q167345
useful as a reference to the platform-specific steps needed to manipulate
DEVMODE.
However, I am curious as to the features you are trying to manipulate that
aren't responding. That is not specifically a function of C#; if you have
some code you'd like to show us to demonstrate the problem, we'd like to
see it. You should direct any inquiries on .NET Frameworks objects to the
public.dotnet.* newsgroups. Thanks!

| I need to be able to change printer settings programatically on the fly. I
| have tried changing printer options using PrinterSettings object but the
| changes never seem to take affect. I have seen the calls to get and
| setHdevmode(). the get function returns an IntPtr. how can you manipulate
| something using this IntPtr. DEVMODE was a structure under C++ but there
| does not seem to be an equivelant under C#.
|
| Please help, my project is dependent on this working.
