[Q] Compile Error? Process is member of the namespace...

[dennis kim]

Hello ^^ I met a problem while learnning Visual Basic.NET

It's a simple program.
But this source isn't compiled by vbc.exe into .NET Framework SDK

C:\vbc Module1.vb (Enter->)

source : Module1.vb
--------------------------------------------------------------------------------------------------
Imports System
Module Module1

Sub Main()
Try
Dim separators As String = " "
Dim commands As String = Microsoft.VisualBasic.Command()
Dim args() As String = commands.Split(separators.ToCharArray)
System.Diagnostics.Process.Start(args(0))

Catch e As InvalidOperationException
Console.WriteLine("Please input the program name to run")
Console.WriteLine(e)
End Try
End Sub
End Module
--------------------------------------------------------------------------------------------------



result :
--------------------------------------------------------------------------------------------------
Microsoft (R) Visual Basic .NET Compiler version 7.00.9372.1
for Microsoft (R) .NET Framework version 1.00.3328.4
Copyright (C) Microsoft Corporation 1987-2001. All rights reserved.

C:\Documents and Settings\Administrator\My Documents\Module1.vb(11) : error
BC30456: 'Process' is not a member of 'Diagnostics'.

System.Diagnostics.Process.Start(args(0))
--------------------------------------------------------------------------------------------------

This source doesn't trouble me at VB.NET RC0 release.
The program built at VS.NET behaves properly.

What's the difference the two?
Do you know that? ^^

Dennis,

>What's the difference the two?

When you create a project in VS.NET, it adds references to a number of
commonly used assemblies for you.

When you build from the command line, you have to explicitly reference
those assemblies yourself

vbc /r:System.dll Module1.vb

Thank you Mattias!

I succeeded in solving the problem.

But practically speaking, I didn't get the desired result.

what I want, ...see below ...
--------------------------------------------------------------------------------------------------
c:\Module1.exe hello.exe (Enter->)

c:\hello,world

--------------------------------------------------------------------------------------------------
Now, My Module1.exe can't print hello,world...

hum~~~~ What's the wrong?
I wish Module1 print hello,world

hello.... world..... -_-;

source : Module1.vb
--------------------------------------------------------------------------------------------------
Imports System
Module Module1

Sub Main()
Try
Dim separators As String = " "
Dim commands As String = Microsoft.VisualBasic.Command()
Dim args() As String = commands.Split(separators.ToCharArray)
System.Diagnostics.Process.Start(args(0))

Catch e As InvalidOperationException
Console.WriteLine("Please input the program name to run")
Console.WriteLine(e)
End Try
End Sub
End Module

Good.


>But practically speaking, I didn't get the desired result.

Sorry, but I still don't understand exactly what you're trying to do.


>c:\Module1.exe hello.exe (Enter->)

What's hello.exe?


>c:\hello,world

And what do you mean by this?


If you want an array of command line arguments in your code, you can
simply type

Sub Main(ByVal CmdArgs() As String)

You don't have to use Command() and String.Split() unless you really
want to.

Hello, Mattias? ^^

Module1.exe is a simple launcher program for the other.

hello.exe is ...

#include<stdio.h>
int main()
{
printf("hello,world");
return 0;
}

or

Imports System
Module Hello
Sub Main()
Console.WriteLine("hello,world")
End Sub
End Moudule


It's a famous & simple program.

I think I can understand my purpose using it.

Present Mudule1.exe can launch any program.
ex) C:\Program window\Winzip\Module1.exe winzip32.exe 'launch winzip

But can't print the result of target program(like hello.exe) on command window.
