I'm working on a large Winforms application dealing with large amounts of data exposed through grids. I see us eventually moving completely to an M-V-VM & WPF implementation but now we're still closer to a ball-of-mud than anything resembling loose coupling. As we evolve toward cleaner separation of concerns, what are some specific patt...

I been wondering about this for a while. It seems like there are so many ways now I don't know when to use what? Or if there is even a point to learn them. Like I don't know if they basically do all the same things and just basically stick with one till you master it then maybe look at other ones. So when I was taking an ASP.NET course ...
I have a minimum-trust AppDomain that is calling (across a remoting boundary) methods in a full trust assembly in a full trust AppDomain. However I am getting lots of security exceptions when making these method calls. It would appear that the minimum-trust 'sandbox' is propagating up the stack its minimal security privileges onto the f...

I'm creating quite a few SSIS packages to drive document composition (e.g. utility bills, statements, etc). These require complex graphs in some cases, mostly bar or line graphs (some with bars and lines) Is there any charting program or library you can build a graph in a WYSIWYG environment (preferably selecting sample data to work off...
I've been trying for a whlie on this, and have so far been failing miserably. My most recent attempt was lifted from this stack code here: http://stackoverflow.com/questions/704636/sending-email-through-gmail-smtp-server-with-c, but I've tried all the syntax I could find here on stack and elsewhere. My code currently is: var client ...

I have a server application that needs to find and exchange small amounts of data with other instances of itself on a local LAN. This is not a critical piece of the application. It must be done peer to peer without a central server or advance configuration. Are there any existing libraries that do something like this? EDIT I shoul...
I've read in a few places now that the maximum instance size for a struct should be 16 bytes. But I cannot see where that number (16) comes from. Browsing around the net, I've found some who suggest that it's an approximate number for good performance but Microsoft talk like it is a hard upper limit. (e.g. MSDN ) Does anyone have a de...

I thought that wouldn't be necessary since strings are immutable. My underlying goal was to create a IEnumerable<string> Split(this String, Char) extension method that allocates no additional me...

Hi all, I have a .NET WebBrowser control that I am using to display some javascript-heavy pages that I've written. The pages use YUI and have been built in a way to be portable. I have just discovered that while I can capture keypress in javascript, I cannot seem to capture keyup or keydown in javascript. This prevents me from hooking ...
