Do a web search for "OCR" or "optical character recognition".

can you find me some sort of a source code for it? because i didnt find any.
the language is C Sharp

what i need is to read text from a bmp, all what i found was Hand Write text recognition, with neural network!

this is too advanced, i want something so simple and somehow accurate.

This sounds like that one C# contest from a few months ago. I don't remember the site though. Maybe someone else does?

I'd say approach the problem iteratively, first just get it to recognize a character, that is some sort of object surrounded by white-space, though by this definition 'i' is two characters so defining what exactly is a character might be a bit difficult. Anyway, when you've got this down, then try to get it to recognize a specific character, like 'A' and work from there. This is not an easy problem, so you should do as much research as you can on current systems. I would recommend going to your local college library and looking there, as this is an old problem and quite a few good papers on the subject probably haven't been posted online yet.
