Are there any free .NET OCR libraries that will run OCR in the application window directly?

Question

I am looking for a free .NET OCR library that can do OCR in a given application window or even an image in memory (I can take a picture of the application window myself).

I looked at tessnet2 and MODI but both require an image located on disk.

I need to use OCR because the application I'm trying to write a script for does some stupid things that cannot be read using the windows API, and I need to clear the data from the screen. I tested both tessnet2 and MODI and both of them can read text mainly, but because it must work in an environment that cannot write to disk, I need it to be able to read directly from the application window or some kind of memory stream .

I think OCR is my only version, but there may be other methods that I don't think about.

Suggestions?

Edit based on comments: Environment is a Windows C # .NET application without disk access. This is an application that has code compiled and executed on the fly, and this code works in a context that does not need any resources other than memory.

As you can see from the example Tessnet page, the library needs to pass the Bitmap so that if you create it using the Image.FromStream Method?

You can create a Bitmap object using this constructor: Bitmap Constructor (Stream)
