What have you done to accomplish this task? Have you googled for any existing projects to see what others have done?

This is not as easy as you may think.

Open-source OCR of acceptable quality if quite hard to find. One popular open-source project which has .NET wrappers is Tesseract:[^].

This is one of such .NET projects:[^].

I found a number of much more interesting works on CodeProject, but I cannot say any of them are complete; there are more of the research projects. Please see the CodeProject articles:

Neural Network OCR[^],
Creating Optical Character Recognition (OCR) applications using Neural Networks[^],
Neural Network Classifier[^],
A C# Project in Optical Character Recognition (OCR) Using Chain Code[^],
Unicode Optical Character Recognition[^],
Hebb neural network[^],
Backpropagation Artificial Neural Network in C++[^],
OCR Line Detection[^].

I have to warn you: some of these works are very good, much better compared to the quality I complained about above, but none of these works is completed into a ready-to-use application. They all require considerable amount of work to complete to such level.

Maybe there are newer projects I'm not familiar with; so it would not hurt if you do your own search in CodeProject and elsewhere. Please, if you find something good, please reply in the comment to this answer.
