Running an executable from my .Net code

[STom]

I am trying to find a way to run a .Net executable from within my vb.net
code. I need to pass parameters into the executable and wait for a return
and check the return value for an error before continuing.

Is this possible to do?

Hi,

Take a look at the process class's waitforexit method and process
startinfo.

Imports System.Diagnostics

Dim psi As New ProcessStartInfo()
With psi
.FileName = "foo.exe"
.Arguments = ...
End With
Dim p As Process = Process.Start(psi)
p.WaitForExit()
MsgBox(CStr(p.ExitCode))

Herfried,

Thanks for your sample. Here are some other questions...

1. If I have 3 string arguments that I want to pass to the executable, with
the .Arguments, is the syntax like :
..Arguments = "one two three" ?

I will have these 3 arguments in string variables already within my coded.

2. Will the ExitCode be a numeric value that I can set within my executable
to return in case there is a failure or is it some generic error number?

Thanks again.

Yes.

You can return an integer value. You can make your 'Sub Main' a function
with 'Integer

Addendum:

You can return an integer value. You can make your 'Sub Main' a function
with...

.... 'Integer' return type and the use 'Return <return value>' to return a
certain value.
