Is there a way to read text(numbers and letters) in an image using C# ? Is this possible and What is the best way to do this ?
Thanks!
http://code.google.com/p/tesseract-ocr/ has some wrapper to use it in .NET, or, simpler:
http://www.codeproject.com/KB/office/modi.aspx but you need to keep an eye to the license since it is a part of the Office suite. In both case you tipically need some pre processing for the image and, as a solution I did in the past, some post processors that using some ehuristict correct the mistaked words.

I am trying to create a piece of software than can manage your computer and clean some things up, and one of the things I am trying to incorporate is adblocking.
I have looked online multiple times for something like this, but haven't found anything. The most I amounted to is the webbrowser class.
If someone could help me discern how to change an html file using the webbrowser class, that would be greatly appreciated.

I am getting a constant stream of radio-frequency data and I want to graph it dynamically like an oscilloscope.
I am using C#. Can I use the chart class for this? Are there any readings or videos to help me learn where to start?
You might want to take a look at the MS Chart controls that come with Visual Studio.
Here's a good place to start:

Someone can explain how Collections.Concurrent library are work ?
How we get the thread-safe ?
Is their performance are good ?
You can inspect the concurrent collections implementation by yourself here (this is for ConcurrentDictionary<TKey,TValue>, other collections you can find using the left navigation pane) and get the exact picture of how they work.
The implementation depends on the collection type. It uses volatile, SpinWait, Interlocked and lock.
More information about performance is available in this paper.

I am near release date for my Excel Add-In and I want to have only one limitation hardcoded in the code. My aim is for people to download and use the tool for free but have a limitation that potentially encourages them to buy the unlimited version. I know that there isn't a truly secure way to add that limitation but I was wondering what is the best way of achieving it. The limitation is simply a hardcoded value that I store in the Properties section of my app. Any ideas how I can make it a bit more secure?

i'm looking for a way to draw something (like a racing map) in C# as i do in for example paint . then pass information to a toy car to follow it. I don't need you to write a code, i just need a suggestion of the way to do it.
I think Unity might be something for you. It's a game engine with a free license, and you can program in C#.
