When i run this code with any exe it look as if outlook as crashed and the cpu on notepad.exe in task manager is 99%, How can i get round this if i run it as shell(cmdline) in works fine but i need to code that run after the shell window as been close?


Private Sub Fax_BW_Click(ByVal sender As Object) Handles Fax_BW.Click

'starting code
Dim PID As Integer
Dim cmdline As String
cmdline = "c:\WINDOWS\notepad.exe"

PID = Shell(cmdline, AppWinStyle.NormalFocus, True, 600000)

MsgBox(Format(PID))

'after code

End Sub

Hi Jonathan.

Try to use the System.Diagnostics.Process class to implement your idea.
You can find some examples in MSDN.

Try the following code.

Try

Dim myProcess As Process
myProcess = Process.Start("Notepad.exe")
' Display physical memory usage 5 times at intervals of 2 seconds.
Dim i As Integer
For i = 0 To 4
If not myProcess.HasExited Then

' Discard cached information about the process.
myProcess.Refresh()
' Print working set to console.
Console.WriteLine("Physical Memory Usage: " + _
myProcess.WorkingSet.ToString())
' Wait 2 seconds.
Thread.Sleep(2000)
Else
Exit For
End If

Next i

' Close process by sending a close message to its main window.
myProcess.CloseMainWindow()
' Free resources associated with process.
myProcess.Close()

Catch e As Exception
Console.WriteLine("The following exception was raised: ")
Console.WriteLine(e.Message)
End Try

but with that you have to wait for the 2sec before seeing if they have exit which is just about ok but not the best.

But why does PID = Shell(cmdline, AppWinStyle.NormalFocus, True, 600000) not work with add-in Express.net

Jonathan,

You emulate calling PID = Shell(cmdline, AppWinStyle.NormalFocus, True, 600000) in pure VBA to make sure if the problem relates to Add-in Express.

Jonathan, what do you mean that it doesn't work with ADX?
I have just tested your code and all works fine.

Private Sub AdxCommandBarButton1_Click(ByVal sender As Object) Handles AdxCommandBarButton1.Click

Dim PID As Integer
Dim cmdline As String = "D:\Windows\notepad.exe"

PID = Shell(cmdline, AppWinStyle.NormalFocus, True, 600000)

MessageBox.Show(PID.ToString())

End Sub

the call

Dim cmdline As String = "D:\Windows\notepad.exe"

PID = Shell(cmdline, AppWinStyle.NormalFocus, True, 600000)


works fine with in my form and then i using ADX with outlook to made it a command bar button and it made outlook crashed (and goes white) and send the cmdline program to 100% put u get still use the computer and the cmdline program

i do the call like
Dim cmdline As String = "D:\Windows\notepad.exe"

PID = Shell(cmdline)


and it works fine with ADX

Hi Jonathan.

Could you show me the code that you use to add a control to Outlook?
