Here is my current swap code for swapping 2 KeyValuePair objects in an array: KeyValuePair<int, T> t = a[i]; a[i] = a[j]; a[j] = t; Would there be any speed advantage to using unsafe code and merely swapping the pointers of the 2 objects? Or does the complier effectively boil this safe code down to effectively ...

When I save a jpg file using bitmap.save, it saves as jpeg 4-1-1 when I specify the encoder and quality, but as 4-2-2 when I don't. I would like to save it as 4-2-2 with a higher quality than the default. Is that possible using bitmap.save? Do I lose anything by saving with 4-1-1? Dim bmp As Bitmap Dim ep As New EncoderParameters(1) Dim...

A few friends and myself have been working on an XNA RPG once a week for the last year. Our battle engine is basically finished, and now we're working on overworld exploration. I've already created crude Tile and TileMap objects that work in this way: Simple 2D array of integer values representing tile (Texture2D) objects in a List Us...
This may be seen as a duplicate of http://stackoverflow.com/questions/3423248/thread-safety-lists-binding-and-wpf, but I post it anyway since I'm not fully happy with the accepted response, and I might be able to express what I suspect is the same question more exactly. Any operations related to UI in WPF/Silverlight must be performed o...

I have a form with a rich text box control. Is there a way to have caps lock turn on whenever the rich textbox control has focus? And turn it off if the rich text box loses focus? I am using C# ...
Hi When I'm reading this tutorial I noticed the following performance tip about using structs in C#: Unless you need reference type semantics, a class that is smaller than 16 bytes may be more efficiently handled by the system as a struct. I looked for similar question in stackoverflow but I found some questions that talks a...
Using this, I can tell Fluent NHibernate to use SysCache as a 2nd Level Cache Provider: MsSqlConfiguration.MsSql2008.ShowSql().ConnectionString(x => { x.Server(@"localhost\ANDREPC"); x.Database("mydb"); x.TrustedConnection(); }).Cache(c => c.ProviderClass<SysCachePr...

I want to run a custom logic, before the page life-cycle, to decide what version of a cached page I want to serve to the user. Example: If the user is not logged, then I go to a cache dictionary, catch a version A of the page and serve to the user. Otherwise, if it's logged, then I'll see if I already cached a version of the page sp...
I'm calling a service reference using WCF, but the service requires plain-text passwords, which WCF does not natively support, so I'm using Yaron Naveh's ClearUsernameBinding implementation. This is getting me half the way there. The service I'm calling is firing (because I can see it insert records into a database), but it's failing on ...
Hi! Why those languages are case-sensitive? I've become curious because I was reading the differences between VB.NET and C Sharp, and VB.NET is not case-sensitive. And I think this way is better, because case-sensitive can only be a source of bugs and bad code. Bad code because there's no reason to have variable's names that differ only...
