Question

Is there any way to pause a process or wait unitl the process is complete before continuing onto the next line of code?

Here is my current process to zip all PDFs and then delete. Currently, its deleting files before the zipping is complete. Is there a way to pause/wait until the process is complete?

    Dim psInfo As New System.Diagnostics.ProcessStartInfo("C:\Program Files\7-Zip\7z.exe ", Arg1 + ZipFileName + PathToPDFs)
    psInfo.WindowStyle = ProcessWindowStyle.Hidden
    System.Diagnostics.Process.Start(psInfo)

    'delete remaining pdfs
    For Each foundFile As String In My.Computer.FileSystem.GetFiles("C:\Temp\", FileIO.SearchOption.SearchAllSubDirectories, "*.pdf")
        File.Delete(foundFile)
    Next

Answer 1

You can use process.WaitForExit method

WaitForExit can make the current thread wait until the associated process to exit.
