Can anyone explain why the check for Alt+Left Arrow key is triggered on a Alt+Right Arrow key press within the ProcessCmdKey method? When I originally coded this method, everything worked. I am beginning to question all my key handlers, but wanted to know if there was a good explaination or if I am missing something. All other key combin...
I am working with the static method Enum.GetValues(typeof(SomeEnum)); This method works great when all you need to do is enumerate the values, but for some reason it returns a very simple form of the Array class. I am trying to find an easy way to turn it's return value into a more "normal" collection class like a regular array or Li...
I discovered this by chance when I have a duplicate key/value pairs in my app.config file for a .NET 2.0 console app. To my surprise, it works and the app reads the latest pair. I was pulling my hair when trying to figure out why I could not fetch the correct value of a key (cause I did not realise a similar key with an old value was low...
Hi After reading on stackoverflow that in the case of checking the format of a DateTime you should use DateTime.TryParse. After trying some regex expressions they seem to get long and nasty looking to cover lots of the formatting. But TryParse requires an "out" parameter and since I just want to do a validation format check I don't nee...

I am binding the datagrid to a list of objects of this class, and I am able to display the enumeration values in a combobox fashion However, the values' names don't make a lot of sense.

I don't know what they use in normal windows searching.But there is a technique in which you use indexing of files at once and then use the index later for faster searching.(e.g. Windows search 4.0) Is there any other way for faster searching than this? Can you elaborate from implementation point of view? (Assuming that I may need to im...
I'm trying to overcome a problem with WCF and enums, where I'm trying to pass an object from the server to the client (or another server), which contains an enum. The enum starts with 1, on purpose. Everything goes fine when the enum is initialized and when the value is defined in it, but when it's not defined in the enum, I get this won...

The solution includes a reusable class called HtmlPageEventManager whose purpose is to subscribe to a given list of HTML events for each new webpage that's opened. A goal is to attach handlers as soon as the user can be...

Is there a limitation on number of properties, methods a C# class can have? I do a quick skim at Standard ECMA-334 and did not find any information on it. Before jumping into why a class with many methods are bad design, I want to be more clear on the intention. Of course I will not be writing a class with large number of methods manua...

Obviously, in order for outside clients to connect to the TcpListener, port 4000 needs to be opened in the firewall; otherwise, no outside connection request would get through. My question has to do with what happens when I accept the connection request like ...
