This can be done assuming that a form is displayed on the screen. You need to add an event handler to each control to capture the keypress event

Imports System
Imports System.Windows.Forms

Public Class Form1
    Inherits Form

    Public Sub New()
        ' Create a TextBox control. 
        Dim tb As New TextBox()
        Me.Controls.Add(tb)
        AddHandler tb.KeyPress, AddressOf keypressed
    End Sub 'New 

    Private Sub keypressed(ByVal o As [Object], ByVal e As KeyPressEventArgs)
        ' The keypressed method uses the KeyChar property to check  
        ' whether the ENTER key is pressed.  

        ' If the ENTER key is pressed, the Handled property is set to true,  
        ' to indicate the event is handled. 

        If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
            e.Handled = True 
        End If 
    End Sub 'keypressed

    End Class 'Form1

Open in new window


You can then add your code in the KeyPressed method, setting e.handled = true if you want to consume the keypress and not pass it to the control.

It would be helpful if you put all relevant information in your post :)

You would need to include this in your code

        If Console.KeyAvailable Then
            KeyPressed = Console.ReadKey(True).KeyChar
            ' Process the key
        End If

ReadKey blocks, so that's why the check for keyavailable is performed.
