I have a Windows form application that users can log into. The application is alone and doesn't connect with anything or anyone. Besides creating a global variable, how could I have an easily accesible variable to check the current users permissions? A not so kosher way of doing things is just pass the ID of the userType in the Form co...
Is it bad to use anonymous types in c#? ...
Hi, In the .NET framework, many of the System.Collection classes have Clear methods on them. Is there a clear advantage on using this versus replacing the reference with a new object? Thanks. ...
Hi I know it is not good to just put a try catch with Exception on it since that could lead to burying problems and other things. I however still don't know if I should do it in my case. My site is heavy ajax so I send json responses back. So right now I have identified some possible exceptions that could be raised like a null referen...
Forgive me for asking a subjective question but I'd really like to know where is the .NET development headed in the near future? Are we going to see more ASP.NET developers or will there be more demand for Silverlight/WPF && WinForms developers? ...
Has anyone had this error with IlMerge? I am trying to merge a few assemblies for a .NET project using the 4.0 Framework. ILMerge /log /lib:..\Libraries /targetplatform:v4 /internalize:..\SolutionFiles\CJCommon.exclude /ndebug /out:bin\Release\Common.dll obj\Release\Common.dll C:\Development\CJCommon\Libraries\FluentNHibernate.dll C:\D...
Today I noticed that C#'s String class returns the length of a string as an Int. Since an Int is always 32-bits, no matter what the architecture, does this mean that a string can only be 2GB or less in length? A 2GB string would be very unusual, and present many problems along with it. However, most .NET api's seem to use 'int' to con...
I'd like to mimic a .NET class signature (and possibly some major pieces of implementation) in a C++ application. I plan on releasing said application under the Boost Software License. Specifically, I'd like to use the TimeSpan and DateTime interfaces, as well as some implementation I found using the handy dandy Reflector tool. Would us...
I know that it is possible to parse an XAML - file at runtime and create an UIElement which I can insert into my pages grid, no problem there. But what I really want is to replace the whole XAML of my page or usercontrol, is that possible, too? Reasoning: I want to give the users of my application the opportunity to have the applicati...
Lets say I have the following code: public class Base { // Some stuff here public int var } public class UsingBase { // Some more stuff here public Base B = new Base(); } Now let's say the actual code of these classes is huge and I would like UsingBase to do some extra stuff. So I'm thinking about subclassing it. Now ...

I know there are plenty of books on C#, but I'd rather learn by reading articles/guides and watching video tutorials. Would Microsoft's MSDN website be enough to teach myself C# in depth? Thank you. *Update:* @Jon Skeet: Thanks for your honest answer. I might just do that then, - I'll get Table of Contents from a C# .NET book and then...
Does VB.NET have LINQ support? I was discussing VB vs C# tonight and I was told that VB is different because it does not handle web services as well as C# and that it does not support linq. Is this true? ...

I am creating a thread A and in that thread creating a new thread B. So how is the thread hierarchy? Thread B is child of Thread A? Or the threads are created as peers? I want to abort the parent thread A which in turn kills/aborts its child threads. How is that possible in C#? ...
I have some Delay to access My remote printer, a RICOH offimatic point. I think this delay become from domain autentification. When I call PrintDialog, this delay is about 3 to 5 seconds. I use some .Net programs. Then when I print a report, delay becomes 4x the PrintDialog Delay (15-20 seconds). Standard Programs (c++) get a 1x del...

I have been using .net remoting with client and server on my dev machine, and everything was fine. And then I've located the server on the other machine, connected with my through a 100-Mbit LAN. It has a VPN connection, allowing it to connect to the internet. Whenever a VPN connection is started, .NET remoting gives out huge lag for ev...
