How to run and communicate a DOS program file in a VB.NET program?

[tsung-yu]

Hello any expert,

I has a vb.net program.
For user requirement, I need to run and communicate an old DOS execution
file.
But, how to run and communicate a DOS program in a VB.NET program?
Should I use the Process or Console class? How to do that?

For example,
If this DOS program name as "pick.exe".

In DOS SHELL, user run the pick.exe then type "command1" and wait to
response1

message.
type "command2" and .
When user receives the response1 message then type "command2" and wait to

receive response2 message, later, user closes the DOS SHELL window.

welcome to pick.exe v1.23
-------------------------
command1
..........
response1 message
command2
..........
response2 message
Thank you very much.

Here is an example, of how to write and get input from the console program.

Module Module1

Sub Main()

Dim myNum As Double

Do While getNumber(myNum)

myNum *= 10
Console.WriteLine("That number multiplied by 10 = " &
myNum.ToString)

Loop

Console.WriteLine("Thank you for using the calculator!")
Console.ReadLine()

End Sub

Function getNumber(ByRef myNum As Double) As Boolean
Dim myVal As String
Console.WriteLine("Please enter a value between 1 and 10 ")
myVal = Console.ReadLine
If Not IsNumeric(myVal) Then
Console.WriteLine("That was NOT a number !")
Return False
Else
myNum = CType(myVal, Double)
Return True
End If

End Function

End Module

End Module

you can't communicate with DOS; DOS is only on Windows 95/98/Me and
none of those support VB 2005.

While DOS may not exist any more, it is fairly simple to communicate
with a *console* application using the Process class and by redirecting
standard input and output as Herfried and OHM suggested.

And .Net 2.0 apps will run on Win 98, Win Me and higher. Only Win 95
is not supported. Taken from Microsoft.com:

Supported Operating Systems: Windows 2000 Service Pack 3; Windows 98;
Windows 98 Second Edition; Windows ME; Windows Server 2003; Windows XP
Service Pack 2

of course, VB 2002, 2003 and 2005 are not supported on _VISTA_ right?

I heard that VB is going away

and that doesn't include NT which is even a worse sin than not
including '95

and I want a reference for that; I dont believe that .NET 2.0 supports
windows 98

you sure can't install VB 2005 Express Edition on Windows 98 can you?

I never said you could. VS 2005 and it's variants are only supported
on Win 2000 and higher. But the .Net framework is supported as I said
earlier. Obviously, using XP or 2000 specific features will render the
app unusable on Win 98.

[dbahooker]

so sorry this is what was hanging me up
o Windows Installer 3.0 (except for Windows 98/ME, which require
Windows Installer 2.0 or later). Windows Installer 3.1 or later is
recommended.

well if 3.0 isn't a requirement then why do they make me install it
before installing SQL 2005?

these fuckers need to learn how to SIMPLIFY
if they had just done as they said; and discontinued the 9x line with
the release of Windows 2000-- then maybe things wouldn't be sooo
complex

it's just laughable now
