Thank you all for your reply's;
At first i want to explain why i wanna do this, it may be answer to f1 fan's question, i find a program that i think it can powers my project, i couldent find the program's source and i said i'm a new programmer at my first message. The program that i find and which can powers my project is so complex so i cant build a program like this at that level. So i want to run this program like a part of my program! (i dont want someone do that program for me

)
f1 fan; i understand that you mean if you were me you add the program as a class library but it doesnt work as a class library or i faild to do that. I have to find a way to run my program as a file browser (like web browser)
plazmo; I already can run the program out of my application, i can add the program as a content but i can't call it :cry: yeah i know i'm a bad programmer in fact i'm not a programmer! sorry for take up your time! i'm a hopeless event! :o
Thanks for all again!... :rolleyes:
