It runs without problems on windows, but not in Linux. The related code roughly looks like this: // derived from a From //... private Timer controlTimer; //.... protected overri...
I need to add some new functionality to an existing interface. There are already a lot of classes in the project implementing it but a few of them wouldn't need the new set of features. My first approach was to just add the new functions to the existing interface and implementing it everywhere, adding do-nothing functions where applicabl...
In Windows Forms programming, I have this general problem. When the page is loading and populating, in some cases I don't want the logic in the event handlers to run.

I'm working on some serialization routines, and I need a way to get the type of an input array. Let's say I have the following object: class myclass { public int foo; public byte[] bar; } Now I can get the type of myclass.foo by using GetType(). And if I say that "myclass.bar = new byte[0]", I can infer that bar is an array ...

I have a fixed-length field I'd like to display path information in. I thought in .NET there is a method that will abbreviate long path names to fit in fixed length fields by inserting ellipsis, for example "......\myfile.txt". I can't for the life of me find this method. ...

This is the scenario: I have a State Machine Workflow using ManualWorkflowScheduler. Say there are 2 states: State1 and State2. State1 contains an EventDrivenActivity1 that has a SetStateActivity1 moving the workflow from State1 to State2. State1 also has a StateFinalizationActivity1. So my question is: When an event is raised and Set...
We need to develop an application which is going to be installed on Virtual Machine running Windows. We all know the performance of the .Net is about the same as the native C/C++ code. Is it also true for Virtual Machines? ...

I am maintaining some code which looks something like this. It's a Windows service which does some work every 30 minutes. The ActualWorkDoneHere method takes about 30 seconds to run, but if it is stopped while running it can leave things in a bad state. What is the best way to prevent that from happening? Should I replace the While(t...

I want to encrypt some server data using .NET's RSACryptoServiceProvider and decrypt it when someone enters a key/password via a web page. What are my options for protecting, or ideally not even storing, the private key on the server, whilst avoiding having the user supply it all each time? Encrypt the private key using a symmetric sys...
A typed array implements both the System.Collections.IList and System.Collections.Generic.ICollection<T> interfaces, which both have their own IsReadOnly properties. But what on earth is going on here? var array = new int[10]; Console.WriteLine(array.IsReadOnly); // prints "False" var list = (System.Collections.IList)array; Console.Wri...
