I'm new to this forum but I I'm trying to find an answer to my question. I've developed an application in VB.Net using the console option. This program runs from the command-prompt and is very basic. The issue I am having is:

1. I compile the program and copy the EXE to a USB key
2. I boot onto the USB key which has basic DOS loaded
3. I attempt to execute the EXE I created in VB.Net and get
the following error:

"this program can not be run in dos mode"

I need to find out how I can get my DOS based application to run under real-dos mode, or if it's possible using vb.net?

Thanks in advance for any assistance.

Here is my code:

Imports System.IO

Module Module1

    Public _IPADDRESS As String = ""
    Public _GATEWAY As String = ""
    Public _SUBNET As String = ""
    Public _IPADDRESS_HEX As String = ""

    Public _SUBNET_HEX As String = ""
    Public _MAC As String = ""
    Public _MAC_Hex As String = ""
    Public arrData As Array
    Public pleasefix As Integer = 0

    Sub Main()

        arrData = Command.Split(" ")

        If Not arrData.Length > 1 Then
            Console.WriteLine("")

        End If

To run .net things, you need all this baggage.

Basic DOS doesn't even know about IP addresses, never mind anything else.

I don't need DOS to know what an IP address is, I need to be able to launch a VB.NET based application, even a HELLO WORLD application under a real-DOS environment.

Read post #2 very carefully,
@salem: .NET Framework is needed to run .net things, you need all this baggage.

.NET Framework sits on top of the windows operarting system.
