I'm working on an application in C#, and need to read and write from a particular datafile format. The only issue at the moment is that the format uses strictly single byte characters, and C# keeps trying to throw in Unicode when I use a writer and a char array (which doubles filesize, among other serious issues). I've been working on mo...

Here is sort of a simplified version of what I have going on. Public Class Foo 'conaints information End Class Public Class myMainApp Dim myHelper ...

I want to create an NSIS installer that checks for the .NET Framework and installs it if it's not there. Can you point me to a script for this? I'm very new to NSIS. ...
How can I do this? Tried using a TypeConverter, but the only thing I could think of was to construct the XML for the types, which doesn't quite cut it. TypeConverters in xaml serialization will escape xml and treat it like plain text. Value converters aren't much better. Now, I'm moving to ISupportInitialize and will throw if changes...
I'm looking for a way to programatically tweak the particulars of a file association on a Windows system. For example, the "Application User to Perform this Action" setting for the "Open" action for a particular file type. Clearly I could do this by modifying the registry directly, but if there is an API I'd prefer to use that as it wou...
In Visual Studio 2008, I'd like to have the internal web server still serve my website on the designated port even after I've stopped debugging. In other words, if my site runs on localhost:2923 once I begin debugging, after I stop debugging I'd still like to go there to have the site run (not in debug mode). Sometimes this works and s...

I'm having an issue with the Columns property, the property is set to as ReadOnly so I can't edit any information in it and need to add columns to the datagrid.

I have a date import project in which the clients send ANSI-latin1 encoded files (iso-8859-1). However... It seems that on a weekly basis we get a surprise file, one that is not of the correct format and the import basically dies horribly and needs manual intervention to recover and move on... Most common bad file formats seem to be e...
I'm trying to understand why the following code results in the encrypted byte array being 16 bytes if plainText is 8 bytes in length. I expected the result to also be 8 bytes in length? private static byte[] encrypt(byte[] key, byte[] plainText) { try { using (MemoryStream ms = new MemoryStream()) { D...

Let's say I have many objects and they have many string properties. Is there a programatic way to go through them and output the propertyname and its value or does it have to be hard coded? Is there maybe a LINQ way to query an object's properties of type 'string' and to output them? Do you have to hard code the property names you w...
Hi, I'm trying to convert a Dictionary in Silverlight to a string. I don't want to use any third-party libraries so would like to use System.Json to do this? The best way I have thought of so far is to add all the items in the dictionary to a JsonObject and then call toString(), any better ideas would be most helpful. ...

I am working on a library designed to communicate (over RS232 serial communication) with external devices. I was thinking about error handling strategy and exceptions seemed to be right and industry standard way of reporting errors. So I read few guidelines on exceptions. One pretty clearly states that I should not worry about performan...
I was asked this question in a .net/C# interview: If we have two threads T1 and T2. T1 acquires a lock on obj1 and then does some processing and acquires a lock on obj2. T2 acquires a lock on obj2 and then does some processing and acquires a lock on obj1. So, we can have a deadlock. What is common technique that we use ...
Hi everyone! I'm very new to JSON, and I need to parse some that an API is providing. A quick google search turned up JSON.NET, so I'm trying to use it now to parse this JSON into a list object. First of all, is JSON.NET the best library to use for this? This is what I'm trying to do: I have a class called Item, for example. The json ha...
