One writes the documentation of a code snippet, and then writes the implementation of the snippet. The visual appearance of the software source code would be a plain document like word, with code paragraphs in it. I am trying to conve...
Printing with the System.WIndows.Forms.WebBrowser control
I'm using th WebBrowser control in the .net 2.0 framework. Is it possible to change the printing behavior so it always prints to the default printer, without showing any dialog to the user?

WinForms: What happens to the values stored in .resx files?
What happens to the name/value pairs stored inside a form's resx file? Are they compiled into the binary when I compile my project? For my particular project, I would like the ability to edit one of these values manually without recompiling (app.config-style), is there a simple way to do this? EDIT: Some people seem to not be getting ...
What's the C# method/syntax for converting an array to a simple string?
What I'm looking for is a basic equivalent of JavaScript's Array::join() whereby you pass in a separator character and uses that in its return string of all the subscripts. I could certainly write my own function using a StringBuilder or whatnot, but there must be something built into the .NET BCL. EDIT: Array of anything, not necessar...
.NET - What's the best way to implement a "catch all exceptions handler"
I'm wondering what the best way is to have a "if all else fails catch it". I mean, you're handling as much exceptions as possible in your application, but still there are bound to be bugs, so I need to have something that catches all unhandled exceptions so I can collect information and store them in a database or submit them to a web s...
Extend No-Constructor class
In C#, is it possible to extend a class that has no constructors? Maybe I'm thinking about this incorrectly and just need a kick in the crotch.

If events are implemented as delegates in .NET, what is the point of the .event IL section?
I've seen some very good questions on Stack Overflow concerning delegates, events, and the .NET implementation of these two features. One question in particular, "How do C# Events work behind the scenes?", produced a great answer that explains some subtle points very well. The answer to the above question makes this point: When y...
Graph rendering using 3D acceleration
We generate graphs for huge datasets. We are talking 4096 samples per second, and 10 minutes per graph. A simple calculation makes for 4096 * 60 * 10 = 2457600 samples per linegraph. Each sample is a double (8 bytes) precision FP. Furthermore, we render multiple linegraphs on one screen, up to about a hundred. This makes we render about ...
Internet Explorer Toolbar Tab Key
I've written a IE Toolbar in C# and everything is working fine except that when I open a child Windows Form from my toolbar, the tab key doesn't work on the child form to allow me to move from field to field. The interesting part is that when I open my child form using form.showDialog() instead of form.show() the tabs work like normal....

If I have a property that I want to let inheritors write to, but keep readonly externally, what is the preferred way to implement this?

How do you run a program you don't know where the arguments start?
The subject doesn't say much cause it is not easy to question in one line. I have to execute a few programs which I read from the registry.

I've been using System.Diagnostics.ProcessStartInfo setting the name of the program and its arguments but I've found a ...

Remote machines cannot connect to Visual Studio web server
Hi guys, I remember when MS was developing Cassini - I believe they rolled it into VS 05/08, so I think this is a Cassini web server question. I am using Windows XP with Visual Studio 2008, and find it quite inconvenient when I want to test a web page/styling with multiple browsers and multiple OSes. Right now I have to deploy the c...
