How do I view Console.Writeline?

I'm rather new to programming.

I've read two VB Express books and everything that I could find concerning Console.Writeline, and yet I still cannot figure out how to view what I write to it.

When I use Debug.Writeline, I can view what I write to it in the "Immediate" window.

I guessed that I should be able to view Console.Writeline in the "Output" window.

Is that correct

I tried things like the example below, and nothing appeared in any of the windows that I looked at:

' System.Console.WriteLine

Imports Microsoft.VisualBasic
Imports System

Public Class TipCalculator
   Private Const tipRate As Double = 0.18

   Public Shared Sub Main()
      System.Environment.ExitCode = Calculator(System.Environment.GetCommandLineArgs())
   End Sub

   Public Shared Function Calculator(args() As String) As Integer
      Dim billTotal As Double
      If args.Length < 2 Then
         Console.WriteLine("usage: TIPCALC total")
         Return 1
      Else
         Try
            billTotal = Double.Parse(args(1))
         Catch
            Console.WriteLine("usage: TIPCALC total")
            Return 1
         End Try
         Dim tip As Double = billTotal * tipRate
         Console.WriteLine()
         Console.WriteLine("Bill total:" & vbTab & "{0,8:c}", billTotal)
         Console.WriteLine("Tip total/rate:" & vbTab & "{0,8:c} ({1:p1})", tip, tipRate)
         Console.WriteLine("".PadRight(24, "-"c))
         Console.WriteLine("Grand total:" & vbTab & "{0,8:c}", billTotal + tip)
         Return 0
      End If
   End Function 'Main
End Class 'TipCalculator

'Example Output:
'---------------
'
'Bill total:       $52.23
'Tip total/rate:    $9.40 (18.0 %)
'------------------------
'Grand total:      $61.63

I'm probably going to kick myself when you tell me the answer, aren't I

Thanks for the help.

How do I view Console.Writeline?

Hi,

Console.Writeline would output the text in the Console or Command Window (DOS type). You must use the Debug.Write to send text to the output window.

Put this in the sub main() section of your module:

Dim x As Integer

For x = 1 To 10000

Console.WriteLine("hello there")

Next

It should open the console window long enough for you to view the ouput.

It is working, probably just too fast for you to see though. I'd use debug.writeline for your samples.

Thanks for the help, guys!

I just have one question for Paul...

I tried using the debug.write method that you told me about like this:

Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim x As String = "Hello World"

System.Diagnostics.Debug.Write(x)

End Sub

End Class

Oddly, it's saying "Hello World" in the "Immediate" box, and not the "Output" box.

Is this supposed to happen

If so, what's the point of the "Output" box

I tried using the console, instead of a windows application, but I still can't seem to find where I can view "the standard output stream".

Am I correct in thinking that it should be viewed in the "Output" window

I tried this code:

Imports Microsoft.VisualBasic

Imports System

Module Module1

Private Const tipRate As Double = 0.18

Public Sub Main()

System.Environment.ExitCode = Calculator(System.Environment.GetCommandLineArgs())

End Sub

Public Function Calculator(ByVal args() As String) As Integer

Dim billTotal As Double

If args.Length < 2 Then

Console.WriteLine("usage: TIPCALC total")

Return 1

Else

Try

billTotal = Double.Parse(args(1))

Catch

Console.WriteLine("usage: TIPCALC total")

Return 1

End Try

Dim tip As Double = billTotal * tipRate

Console.WriteLine()

Console.WriteLine("Bill total:" & vbTab & "{0,8:c}", billTotal)

Console.WriteLine("Tip total/rate:" & vbTab & "{0,8:c} ({1:p1})", tip, tipRate)

Console.WriteLine("".PadRight(24, "-"c))

Console.WriteLine("Grand total:" & vbTab & "{0,8:c}", billTotal + tip)

Return 0

End If

End Function 'Main

'Example Output:

'---------------

'

'Bill total: $52.23

'Tip total/rate: $9.40 (18.0 %)

'------------------------

'Grand total: $61.63

End Module

Does that seem like it should work

hi,

i guess the problem is this , the console is faster than what your eyes can see , it open and write all lines and find nothing else to do so it close, to keep it open add this to the end of your process

Console.ReadLine()

i guess your problem in that line because it suppose to perform your operation durig exist your process so you will not see it

System.Environment.ExitCode = Calculator(System.Environment.GetCommandLineArgs())

try it this way

Public Sub Main()

Dim billTotal As Double

Console.WriteLine(" what is the bill total ")

billTotal = Console.ReadLine()

Dim tip As Double = billTotal * tipRate

Console.WriteLine()

Console.WriteLine("Bill total:" & vbTab & "{0,8:c}", billTotal)

Console.WriteLine("Tip total/rate:" & vbTab & "{0,8:c} ({1:p1})", tip, tipRate)

Console.WriteLine("".PadRight(24, "-"c))

Console.WriteLine("Grand total:" & vbTab & "{0,8:c}", billTotal + tip)

Console.ReadLine()

End Sub

hope it was helpfull
