I developed a win forms app targeting .net 2.0. All of this is in Visual Studio 2008 sp1. I did this because I didn't really need 3.0+ features in the app. and I didn't want the clients to have to install a gigantic framework when they could just install a semi-huge one. Well, when I create a setup project for the app, build it, instal...

Do you think the advantages of .net35 outweigh the hassle o...

My deployed application uses ReportViewer (CLR 3.5) to print locally reports. Recently users noticed problem with printing. I've investigated that and turned out that in some PC reportViewer set page format to Letter (instead A4) that's why printouts are cut.

How do you disable additional checkbox selections/deselections without sacrificing the functionality of the ListView? I know you can call: ListView.Enabled = False, but that also disables any scrolling within it. For example: I have a timer that starts a backup based on the Listview items that are checked. After a certain time, I don...

For example, write my own POCO Person that accepts one of my code-gen'ed Entity Framework object EFPerson to initialize the POCO ...
