I appreciate any suggestions on a database for the following problem:
Contains < 200 MB read-only data
Data is quite tabular with limited relationship to other tables
Must query tabular data and put into C# structure (to be feed to an interpolation routine)
It will be accessed by C# routine. This routine will exist in desktop application and behind ASP.net application.
Encryption required for desktop install
SQL not necessary
Component must support concurrency
Thanks in advance.

If I were you, I would put the data into C# structure, and serialize it to disk. 200 MB seems like an amount, which would safely fit into RAM. While serializing/deserializing, you can pass it through CryptoStream, and get encryption requirement covered that way. Whole database layer could be so simple, it would fit on one screen.

I have an application which could easily be controlled by a bot over network or even on the local machine(which simuates keyboard and mouse e.g.).
I want to avoid this using a captcha. The source has to work without internet / has to be generated during runtime on the computer itself.
Is there any open-source project for this or can someone give me a code example or a link ?
I've found an article "Simple CAPTCHA, Create your own in C#" by Raymund Macaalay. It is for an ASP.NET app, but he generates a normal C# bitmap image using different random fonts in STEP2, so this should also work in your WinForms app.

I'm busy with an application that needs to display Treemaps to a user but I can't find a good charting library that has support for this kind of graph.
Here are some examples of what I mean
I'm using C# as a server side technology, but I'm willing to invoke something on a command-line too if that is required.
Any suggestions?
Edit: I don't mind getting a java library recommendation, since I don't mind combining technologies
Well, since you question is tagged with "Java" I'm gonna propose JFreeChart (even though your actual question seems to indicate you need more of a C#/.net kind of library)

Does anyone know of any APIs available for Microsoft's Zune application? I want to modify the ratings of the songs that are loaded in Zune without having to open the Zune app. There is a ZuneStore.sdf database sitting in my AppData folder, but I cannot open it in Microsoft SQL Management Studio as it looks to be a special format. Surely there must be some way to modify this data?

I can open the Zune database in SSMS 2008, but it is not in a standard SQL Compact format, so cannot run any queries against it. Consider it to be in a proprietary, undocumented, protected format.
So I guess not.
This is the closet I have found to an API. It controls the Zune player. Going to see what I can do with this.

I want to visualize components and connections of a HVAC system with .NET/C#.
The diagrams will just include a few different components and their connections.
They do not have to comply to any formal standard and should look alike the diagrams attached. In addition the user should be able to select a single component/connection (so that I can display additional data).
Which free drawing/charting library would you use and why?
Thanks for your time.
Julian,
Please check out GraphSharp: http://graphsharp.codeplex.com/Release/ProjectReleases.aspx
Small/open source C# library on Git renders to HTML5 (You can modify to render to for example WPF or Winform as well)

I would try to host VS studio designer in application , how you can host workflow designer for instance. Read about VS extensibilities
It doesn't get more free than System.Drawing...
Seriously, given your requirements I'm not sure you need a framework or library. The most complex part of the system you describe is drawing the lines between components. If that doesn't have to get fancy (automatic layout, detecting where the lines overlay other lines/boxes) then you can probably roll the whole thing custom.

I need to minify some C# code in a handful of Silverlight .cs and .xmal files. What are your tips for maintaining one code base and running a "tool" to generate minified code for a project?
Are there any tools (like Resharper) that will do this? If not fully, partially or assist in some way...
EDIT: I realize that there is no need for C# minification. This is an exercise that I'm doing that does not make sense on the face of it. (This is not homework.)
How about a source-code obfuscator? They generally abbreviate names, etc - and certainly remove white space.
For example, here, with demo here (although you'd probably want to disable the string encoding if possible). Note that this isn't a direct recommendation: this is just the first hit I got for C# code obfuscator.
Is that necessary? It was my understanding that the compiled .Net assembly would be sent across the wire, not the C# (or whatever language) source code.
