[RESOLVED] Pause application until process finished

I've spent the last two hours trying to figure this one out,but no luck.
Basicly it's pretty simple.When a button is clicked,my program gets the list of all Drives on a current computer.

Then I use String.Concat to merge the drive letter and the rest of the path.
So I get something like: "C:\" + "somefolder\somefile.some_extension"

That creates a full path to a file I am looking for.Then I check if that file exists.If it doesn't exist,I use Process.Start to run the setup file(to install the program I need).

It works well and installs the program I need.

The Problem:
I want my application,after the installation is finished,to check again if the program is installed and ofcourse confirm that it is.

This is my code:

Code:

---

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
   
        Dim DriveList As String() = Directory.GetLogicalDrives()

        Dim Drive, FullPath, Path1 As String
        Dim EmptyDrives As Integer

        Path1 = "wamp\wampmanager.exe"
        EmptyDrives = 0

        For Each Drive In DriveList

            FullPath = String.Concat(Drive, Path1)
            If File.Exists(FullPath) Then
                MsgBox("Wamp server is installed and can be found at: " & FullPath)
                Exit Sub
            Else
                EmptyDrives = EmptyDrives + 1
                If Directory.GetLogicalDrives.Count = EmptyDrives Then
                    Dim AppPath As String
                    AppPath = My.Application.Info.DirectoryPath
                    If MsgBox("We could not detect Wamp server on this machine!" & vbNewLine & "Would you like to install Wamp Server now?", MsgBoxStyle.YesNo) = MsgBoxResult.Yes Then
                     
                        Process.Start(AppPath & "\WampServer20h.exe")



                    End If

                End If
            End If

        Next Drive



    End Sub

---

Replace this line:

Code:

---

Process.Start(AppPath & "\WampServer20h.exe")

---

With this:

Code:

---

Process.Start(AppPath & "\WampServer20h.exe").WaitForExit()

---

Then your app will block on that line until the process exits. Ideally you would do this in a background thread so that your application's user interface does not freeze but that may not matter that much in your case, I dont know.

PS instead of using String.Concat to combine file paths, you can use the 'proper' method which is IO.Path.Combine ;)

Thank you,it works!
Resolved!

No problem :) dont forget to mark the thread as resolved by using the Thread Tools menu at the top of the first post ;)
