System.Diagnostics.Process.Start and UI 2004

[Former Member]

Can anyone tell me if (how) I can use System.Diagnostics.Process.Start to spawn external applications from a trapped item event in my add-on?

My application model is the standard startup/sub main. It looks like this:

Module Startup

Sub Main()

Dim oAV As MyObject

oAV = New MyObject

' Startup

System.Windows.Forms.Application.Run()

End Sub

End Module

MyObject contains a "New()" that sets the SBO_Application object etc. It also contains a few subs that capture events in the sbo UI such as button presses. Now, the trick - how do I set up my threading model correctly to allow me to launch an external application like calculator from within the UI?

Thanks in advance!

Dim ProcID As Integer

' Run Calculator.

ProcID = Shell("C:\Windows\system32\calc.exe", AppWinStyle.NormalFocus)

Seems to work but I was hoping to use .Process.Start

It sounds like you are having a problem becuase you are launching your application (calc.exe in example) under a thread that is then closing. You can use the invoke delegate to launch from the 'parent' thread. You will probably have to make a delegate function and call that with me.invoke(delegate)

Look at 'invoke' in the msdn.
