Check for pressed key in console application

[Marco Singer]

Hi all,

is it possible to check if a key was pressed in a VB.NET console
application?

I have a loop which runs a long time and want it to exit if a key was
pressed. What I NOT want is to wait until a key is pressed...

Thanks

Marco

Marco,

Can you try if something silly as this fits your problem as sample?

I hope this helps?

Sub Main()
Dim myProcess As New Process
myProcess.StartInfo.FileName = "Sort.exe"
myProcess.StartInfo.UseShellExecute = False
myProcess.StartInfo.RedirectStandardInput = True
myProcess.Start()
Dim FT As System.Threading.Thread
FT = New System.Threading.Thread(AddressOf DoSomething)
FT.Start()
Dim inputText As String
Dim numLines As Integer = 0
Do
inputText = Console.ReadLine()
Loop While inputText.ToLower <> "stop"
FT.Abort()
myProcess.Close()
End Sub
Private Sub DoSomething()
Dim A As Integer = 1
Do
A = 1 * A
Loop
End Sub

That's not supported by the current version of the 'Console' class.

Herfried,

Have a look at my sample provided in this thread.

Something wrong with it, it was just an idea?.

'ReadLine' will return only if the return key is pressed...
