There is a PrintingPermission attribute in the framework which takes a PrintingPermissionLevel enumeration with one of these values;

NoPrinting: Prevents access to printers. NoPrinting is a subset of SafePrinting.
SafePrinting: Provides printing only from a restricted dialog box. SafePrinting is a subset of DefaultPrinting.
DefaultPrinting: Provides printing programmatically to the default printer, along with safe printing through semirestricted dialog box. DefaultPrinting is a subset of AllPrinting.
AllPrinting: Provides full access to all printers.

The documentation is really sparse, and I wondered if anyone can tell me more about the SafePrinting option. What does the documentation mean when it says "Provides printing only from a restricted dialog box." I have no idea what this means. Can anyone shed any light?

This subject is touched in the MS certification 70-505: TS: Microsoft .NET Framework 3.5, Windows Forms Application Development and so I'm keen to find out more.

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
