Retrieving parameters passed to exe

[CryoEnix]

Hey peeps, does anybody know how to retrieve the parameters passed to the compiled exe at runtime? In Java you get an array of strings right in front of you (args[]), so how is this done in VB.NET?

 

Thanks

Just add an array of strings as the parameter of the Main method.

Sub Main([b]ByVal args() As String[/b])
   ....
End Sub

Sub Main([b]ByVal args() As String[/b])
   ....
End Sub

 

...That does seem a little too easy...

By the 'Main' sub, are you referring to form_load? There are already two parameters in there by default:

 

(ByVal sender As System.Object, ByVal e As System.EventArgs)

In VB, you don't need a special "Main" method in a windows app (I think it generates one behind the scenes).

 

So you can either add one to your form:

Public Shared Sub Main(ByVal args() As String)

   ' Starts the app with whatever form you want:
   Application.Run(New Form1())

End Sub

or you can use Environment.CommandLine.

 

PS: Just in case this wasn't clear, the form_Load() is an event which is called when the form loads, and it is not the "Main" subroutine, therefore you cannot add the parameter args().

The way to do it is using Environment.GetCommandLineArgs

 

Environment.GetCommandLineArgs.Length is the count of parameters present

Environment.GetCommandLineArgs(n) is the nth comand line arg

 

That is all you need

Cheers guys, You've both been a great help.

 

Additionally:

 

Blackstone, The Main method you're referring to - does it run on startup like the one in Java, or does it need to be called?

[BlackStone]

It runs on startup (in a Windows App, you have to change the startup object to "sub Main()" )
