(VB.Net) How do I call an external program?
I'm writing a simple, console VB.Net program, and I can't seem to get it to run other programs from within it.

I've been reading up on the question, and most people suggest either calling Shell from the Microsoft.VisualBasic.Compatibility namespace, or calling System.Diagnostics.Process.Start("Program to execute"). I can't seem to get either approach to work.

I've got a skeleton program (just a module declaration with sub main in it) written to try to test it, but I can't get it to work.

Could someone explain to me how to do this?

Talking Shell function Maybe multithreading
Try using Shell("c:\windows\notepad.exe"). The Shell function still exists in VB.NET. I just had to solve this problem myself. You put the path of the program as the arguement.

If you're looking for Mulithreading try looking up Asynchronous Programming in the MSDN. I haven't actually done any multi threading with VB.NET yet.

Dim myprocess as new System.Diagnostics.Process()
myprocess.startinfo.filename = "c:\somepath\processname.exe"
myprocess.startinfo.Arguments = "/someargument"
myprocess.start

The myprocess.startinfo.arguments is optional, and if you google the system.diagnostics.process.startinfo namespace you'll find all sorts of other functionality you can incorporate into your external process manipulation.

Hope that helps.
