Is there a standard connection pooling model (or API) similar to that used by the data providers in .net that I could use to implement my own connection pool? I ask because I have a requirement to implement my own connection pool to a proprietary TCP/IP device that we use in a web service. The current problem is that there are lot of co...
I'm trying to find a way to stop, start, restart/recycle websites and application pools from within a web interface on the same server. Ideally this would be something I could do with .Net without having to execute shell commands. (I see other related quesitons have been asked but I don't want to do this from the command line unless th...
I tried to see the implementation of [MethodImpl(MethodImplOptions.InternalCall)] public extern int get_Length(); fucntion, which in turn is Length property of string. But reflector gave me the following error "The member is not loaded or may be hidden due to your visibility settings" However the member is loaded and the visibility set...
I have an two-dimensioanl array of sARGB colors (System.Windows.Media.Color) describing what I want to write in a WritableBitmap. The array is the same width and height than the expected bitmap. The problem is that, as long as I can see, the WritePixels Method of the WritableBitmap expects an array of integers. How do I convert my col...

I am trying to figure out what devices are online and offline in our LAN. I've seen many programs doing a kind of graphical network overview, presenting LAN IP and MAC addresses. I would like to know if and how those (ARP?) information can be pulled from C#/.NET ? Any sample code snippets/links would be appreciated. ...
In my application, I allow the user to select items that correspond to files on a disk. When the user presses Ctrl+C, I want the file to be sent to the clipboard, where the user can then paste the file somewhere else. I want to implement it in a way so that the user can copy, but not paste inside my application. The user is then free to...
Just some architectural question: I use ASP.net MVC and exclusively rely on Strongly-Typed Views with View Model Classes. As presentation is the job of the View, these Classes do not only contain some fields, but also some formatting functions, e.g., // The ViewModel contains a List<Comment> which the view.aspx iterates // through, cal...

I've been looking for similar way in .NET I've tried // When the user press Ctrl-S // Apply any pending edit this.TheDataBindingSource.CurrencyManager.EndCurrentEdit(); // then save the data this.S...
Actually the question should be why does Console.WriteLine exist just to be a wrapper for Console.Out.WriteLine I found this little method using intellisense, then opened .NET reflector and 'decompiled' the code for the Console.WriteLine method and found this: public static void WriteLine(string value) { Out.WriteLine(value); } S...
I've read about it on msdn and on CLR via c#. My main question about it is the following: let's imagine we have a 2Mb unmanaged HBITMAP allocated and a 8 bytes managed bitmap pointing to it. What's the point of telling the GC about it with AddMemoryPressure if it is never going to be able to make anything about the object, as it is allo...

Let's imagine I have an application where basically every now and then I will click on a button, a lot of things will happen for a couple of minutes, and then it'll stay idle possible for another hour, or maybe just 1 minute. Wouldn't just after that whole ended a good situatio...

I belie...

(and i don't want to use 'user' app config) i want to write to the app.config values, i tired the above method of k...
