How do I allow multi-select in a .NET TreeView?
I'm stuck in .NET 2.0 Windows Forms. It doesn't look like the ability to select multiple nodes doesn't exist in the standard TreeView control. I'm trying to do this for context menu selection. So check boxes aren't an acceptable UI paradigm here. What's the best way to provide that very necessary functionality? ...
Are Microsoft's Own Implementations of Their OpenSource Counterparts Better, and Why?

Storing credit card details
I have a business requirement that forces me to store a customer's full credit card details (number, name, expiry date, CVV2) for a short period of time. Rationale: If a customer calls to order a product and their credit card is declined on the spot you are likely to lose the sale. If you take their details, thank them for the transacti...

Are there any classes in the .NET framework I can use to throw an event if time has caught up with a specified DateTime object? If there isn't, what are the best practices when checking this? Create a new thread constantly checking? A timer (heaven forbid ;) )? ...
TCP connection quality in .NET
I have a mission-critical real-time data application that uses a TCP connection between the client and server. In some cases, the connection periodically dies (SocketException).

Is there any way I can get .net stack traces in Sql Profiler, or a similar tool?
In my previous job I designed and helped build a run-time(production) Profiler tool that among other cool features was able to give me .Net stack traces for every SQL statement that executed. Think of it as SQL-Server Profiler on steroids. So instead of just seeing SQL statements and duration, you also got the context in which the SQL ex...
Is FxCop's CollectionPropertiesShouldBeReadOnly rule incompatible with the spring framework?
FxCop has the CollectionPropertiesShouldBeReadOnly rule that complains if your class has some kind of collection property that clients can set. Instead, it suggests making the property read-only and supplying a Clear() method and Add() or AddRange() methods for changing the contents of the collection. I agree that makes for a cleaner an...
Is there an equivalent to Java's "kill -3" for a .NET CLR thread dump?
Hi, Java has the thread dump which is triggered by a signal 3 sent to the process (e.g. "kill -3 PID"). The equivalent I've found for .NET is to use ADPlus (http://support.microsoft.com/kb/286350). This basically attaches a debugger, takes a mini dump, and executes a few commands. I find .NET's approach to be a very brute force, cludgy a...

What's the best way to learn .NET?
I've been developing Java EE for quite a while now. I've used WebLogic, Tomcat, Spring, and Hibernate extensively, so I have a mental model of what features are available and how things are developed and deployed. The problem that I have with .NET is that I don't have a clear mapping of its features onto Java EE. Here's what I know so...
