在一个过程完成时启动外部过程

Question

Stupid question, but I am starting a couple external applications (all .exe) . After the process is started, how can I make my program wait until that process ends to start another process?

Example'

'Start application
 Process.Start(My.Computer.FileSystem.CurrentDirectory & "SomeEXE1.exe")

**' A if statement or something to state that SomeEXE2.exe will NOT start until SomeEXE1.exe finish.**

 Process.Start(My.Computer.FileSystem.CurrentDirectory & "SomeEXE2.exe")

Answer 1

Just call:

Process.WaitForExit

on that instance of Process .

Answer 2

How about using Shell?

Dim pID As Integer = Shell(thePathOfEXE, AppWinStyle.NormalFocus, True, 30000)

Will launch the exe passing the processID back to pID, normal focus and wait until completed execution or until 30 seconds have passed. The 30000 could be -1 if you're not interested in a timeout.
