Run A .exe File From Inside A VS2010 Project?

I am currently working on a school project in VS2010. I have added a .exe file in the project folder and added it to the Project as a 'Existing Item'. In Project Properties -> Publish -> Application Files the .exe file is shown.

The .exe file runs quite nicely when I use the Process.Start("C:\NameOfMyApplicationFolder\MyProgram.exe") hard code path to the .exe file. However, I am faced with two(2) challenges that I need to overcome. These are they:

1. If published on another machine the .exe file will not run as the hard code path to the .exe file will be different from that on my machine. Therefore I need a way to create a generic path to the .exe file. I have tried these [Process.Start("C:\|DataDirectory|\MyProgram.exe")] AND [Process.Start("Localhost\|DataDirectory|\MyProgram.exe")]; I got an error message that "The system cannot find the file specified".

2. I am putting the Process.Start("xxxxx.\MyProgram.exe") on a button click event. I also want to put the running of the .exe file between two(2) lines of code. The first line of code is basically asking "Do you wish to run the executable file" - YesNo. If 'Yes' is selected the .exe file is run. Here is the problem: When the .exe program is closed the second line of code is to be executed. I have gotten the .exe to run (using the hard code file path) when 'Yes' is selected, and the second line of code to execute if 'No' is selected, but I have not been successful in getting the second line of code to execute after closing the .exe program. I have tried this: [If Process.Start("C:\NameOfMyApplicationFolder\MyProgram.exe").CloseMainWindow = True Then Do line 2 End if]. nothing happens when I close the .exe program.
