How to pass cmdline args to a Windows App?

[Tom Bower]

I have a simple one-form Windows App I'm working on in
VB. I need to be able to pass some command-line
parameters to the application in order for it to do what
it needs to do when it fires up.

Any pointers on how to do that?

\\\
Public Sub Main(ByVal astrCmdLineArgs() As String)
Dim i As Integer
For i = 0 To astrCmdLineArgs.Length - 1
Console.WriteLine(astrCmdLineArgs(i))
Next i
End Sub

\\\
Public Sub Main()
Dim i As Integer
For i = 0 To Environment.GetCommandLineArgs().Length - 1
Console.WriteLine(Environment.GetCommandLineArgs(i))
Next i
End Sub
///

In order to test the samples above, you must set the application's
startup object to 'Sub Main'. The 2nd sample code can be used at any
place inside a Windows Forms application too.

Hey, that's cool, they're right there. And I even
figured out that you can pass sample ones using the
debugger by setting them in the Project's Debugging
Properties page.

Thanks, this forum is very helpful.

The 2nd sample code can be used at any
place inside a Windows Forms application too.

But it has the downside of requiring EnvironmentPermission read access
to the %PATH% variable, which might not be granted in a partially
trusted environment.
