Is there a way for an app to present the user with the UAC prompt only once, upon first running. Thereafter, no further prompting. In other words, I understand that our app needs the user's UAC permission to do certain things. And that's fine. But we don't want it to have to keep asking on every occasion it runs. Can the user give permi...
int a, b, c, d, e; a = b = c = d = e = 1; if ((a==b) && (b==c) && (c==d) && (d==e)) { Console.WriteLine("that syntax is horrible"); } is there a more elegant way to test multiple equality as above? maybe an AreEqual(params obj[]) or something? I had a google but didn't find anything. ...

Hi I like the C# 3 initializer syntax and use it a lot, but today while looking in Reflector, the following came up: var binding = new WSHttpBinding { ReaderQuotas = { MaxArrayLength = 100000 }, MaxReceivedMessageSize = 10485760 }; At first I thought it was a mistake, but it does compile! Guess I am still learning new stuff all t...
Possible Duplicates: Why doesnt .Net have a Set data structure? C# Set collection? Just curious as to why Sets were left out of .NET collections. It seems like a pretty big omission, and I wondered what the reason might be. BTW I know that there is HashSet in .NET 3.5, but it did take Microsoft a long time to get around to p...

Hi How can I force a shrink of a DataTable and/or List so that I can free memory efficiently? I am currently removing the processed row from the DataSet every iteration of the loop, but I'm not sure if the memory is being released. for (int i = m_TotalNumberOfLocalRows - 1; i >= 0; i--) { dr = dt.Rows[i]; // Do stuff dt.Rows.R...

[XmlElement("Dest")] public XmlNode NewValue { get; set; } The real problem here is that sometimes in this implementation the XmlNode can be an XmlElement or XmlAttribute. when it's an element this code works fine, but when it comes ...
I have a personal project written in VB10, and am publishing it from VS2010. However, when users attempt to run the created setup.exe, they receive an error stating .net 4.0 is required. At first I assumed I had simply not set the framework as a prerequisite, but I do have "Microsoft .NET Framework 4 (x86 and x64)" checked as one of the ...
The process of converting from Visual Studio .NET 2003 to Visual Studio 2008 is satisfyingly start forward. I thought it would be worth asking a couple of questions though: 1) Are there any 'gotchas' with this conversion process that we should be aware of? 2) Same question goes for upgrading the .NET Framework from 1.1 to 3.5? Thanks...
