i kinda got an idea, to make a app similar to cmd prompt, but this is for my own purpose, to make my life a lot easier, for example, the app i will use for everything on my pc no need to explain but, i kinda started and i got stucked from start, basically the form has 1 richbox and 1 textbox, the richbox is like the screen of the cmd prompt, and in the textbox you enter commands, but how to make the textbox to recognize parameters for command?! for example if i want to open a directory for given location, i would need to write "/opendir "c:\windows\fonts"", but how to do this? since i started recognizing commands using switch, i guess you understand me, if not ask me for more info, i kinda feel dumb right now .. anyway thanks in advance.
