I found the console.clear method, but when I run it it fails with an
uinhandled exception and the exception is that it does not have the

to the window.

IM assuming, I need to determine the console windo handle, but Im not
sure,
has anyone used this, can point me in the right direction.

Thanks a million

I'm not sure I follow you - I can use Console.Clear with no problems:

////////////////////////
Module Module1

Sub Main()
For i As Integer = 0 To 5
Console.WriteLine("hello world {0}", i.ToString())
Next i

System.Threading.Thread.Sleep(1000)

Console.Clear()

Console.WriteLine("Console Cleared")

Console.Read()
End Sub

End Module
////////////////////////

The above runs with no problems for me - is it throwing an exception
for you? If not please post a small but complete code sample that can
reproduce the error for me.

Thanks,

Alright, would you mind posting some code that I can use to replicate
the problem?

Thanks,

Okay, now I'm getting worried. Did you run the application without the
Console.Clear() call? Unless I've really forgotten something Window's
based applications ignore the calls to the Console class, as it
doesn't exist.

Excerpt from the MSDN documentation (http://msdn2.microsoft.com/en-us/
library/system.console(VS.71).aspx):

<quote>
The Console class provides basic support for applications that read
characters from, and write characters to, the console. If the console
does not exist, as in a Windows-based application, writes to the
console are not displayed and no exception is raised.
</quote>

If you really need to have both a console window and standard forms
you need to create a console project. Then reference the appropriate
dll's (such as System.Windows.Forms) and then create the form classes
you need.

The following code sample requires a new console project and
references to System.Windows.Forms and System.Drawing to work.

////////////////
Imports System.Windows.Forms
Imports System.Drawing

Module Module1

Sub Main()
Application.EnableVisualStyles()

Console.WriteLine("Showing form...")
Console.WriteLine("Be sure to look behind me, the form is
sometimes hidden behind me")
System.Threading.Thread.Sleep(1000)

Dim f As New Form()
f.Text = "My Custom Form"

Dim b As New Button()
AddHandler b.Click, AddressOf button_Click
b.Width = 100
b.Location = New Point(100, 100)
b.Text = "Click Me"
f.Controls.Add(b)

f.ShowDialog()

Console.WriteLine("You just closed the form")
Console.WriteLine("Goodbye")

System.Threading.Thread.Sleep(1000)
End Sub

Private Sub button_Click(ByVal sender As Object, ByVal e As
EventArgs)
Console.Clear()
Console.WriteLine("Hello World from the Windows Form!")
Console.WriteLine("The current time is: {0}",
DateTime.Now.ToString("h:m:s tt"))
End Sub

End Module
////////////////

Hope That helps!
