[mareshka]

Hello, i am analysing text, and searching for some examplse of analysing text doing with windows from application,
I have a field in gui where i should type a math equatation like "7*(5+3)" and get the result. So i need to analyse it. Maybe anyone got an example?

I am a begginer of windows form application.
