Visual Basic Clipboard, Copy, Paste, and Processes

Hello,

The short version of what I am trying to do is:
1) Use

Code:

Process.Start

to begin a process - this is working for me
2) Copy variable to the clipboard - I can do this with the

Code:

My.Computer.Clipboard.SetText

command.
3) Past the variable when the

Code:

Process.Start

program requires it - I should be able to do this by using CRTL+V but I would like to automate it if possible though I cannot modify the Process.Start program so I may be stuck with CRTL+V
4) When the text is pasted into the Process.Start program I want to change the clipboard contents to another variable string so I can CRTL+V the new contents into the second Process.Start input prompt. - I have no idea on how to determine if the previous information has been pasted **This is my biggest challenge so far**
5) Finally how do I do this all while NOT running the secondary

Code:

Process.Start

that follows after the first one? - I am currently (without using copy/paste) using

Code:

.WaitForExit()

on the process, but I don't think that will work if I am going to be copy/pasting information.

Thank you.
