I see this has been answered  but it seems like you could avoid all of this  remapping  of the enter key by simply hooking your validation into the AcceptButton on a form  ie  you have 3 textboxes  txtA txtB txtC  and an  OK  button set to be AcceptButton  and TabOrder set properly   So  if in txtA and you hit enter  if the data is invalid  your focus will stay in txtA  but if it is valid  assuming the other txts need input  validation will just put you into the next txt that needs valid input thus simulating TAB behaviour    once all txts have valid input  pressing enter will fire a succsessful validation and close form  or whatever     Make sense

Make sure the form KeyPreview property is set to true   Private Sub Form1 KeyPress ByVal sender As Object  ByVal e As System Windows Forms KeyPressEventArgs  Handles Me KeyPress     If e KeyChar   Microsoft VisualBasic ChrW Keys Return  Then         SendKeys Send   TAB            e Handled   True     End If  End Sub

I have test this code on Visual Studio 2019  Its working superb   Just Paste it into you form code   it will work on all textboxs on same form   Protected Overrides Function ProcessCmdKey ByRef msg As System Windows Forms Message  ByVal keyData As System Windows Forms Keys  As Boolean     Dim keyCode As Keys   CType msg WParam  IntPtr  ToInt32     Const WM KEYDOWN As Integer    amp H100      If msg Msg   WM KEYDOWN AndAlso keyCode   Keys Enter        AndAlso Me ActiveControl GetType Name    TextBox  Then         Me SelectNextControl Me ActiveControl  True  True  False  True          Return True      End If     Return MyBase ProcessCmdKey msg  keyData    End Function

There is no need to set the KeyPreview Property to True  Just add the following function   Protected Overrides Function ProcessCmdKey ByRef msg As System Windows Forms Message                                               ByVal keyData As System Windows Forms Keys                                               As Boolean      If msg WParam ToInt32     CInt Keys Enter  Then         SendKeys Send   Tab            Return True     End If     Return MyBase ProcessCmdKey msg  keyData  End Function   Now  when you press Enter on a TextBox  the control moves to the next control

I had the same problem and I could not make this answer work on Framework 2 0 so I dug deeper   You would have to first handle the PreviewKeyDown on the textbox so when  ENTER came along you would set IsInputKey so that it could be handled by or forwarded to the keyDown event on the textbox  Like this   Private Sub txtFiltro PreviewKeyDown ByVal sender As System Object  ByVal e As System Windows Forms PreviewKeyDownEventArgs  Handles txtFiltro PreviewKeyDown     Select Case e KeyCode         Case Keys Enter             e IsInputKey   True     End Select  End Sub   and then you would handle the event keydown on the textbox  One of the answer was on the right track but missed setting the e IsInputKey   Private Sub txtFiltro KeyDown ByVal sender As System Object  ByVal e As System Windows Forms KeyEventArgs  Handles txtFiltro KeyDown     If e KeyCode   Keys Enter Then         e handled   True         Textbox1 Focus       End If End Sub

Use KeyDown Event instead of KeyPress  If e KeyCode   Keys Enter Then    MsgBox   You pressed enter   End if   Note  Make sure you don t have ACCEPT BUTTON set on your form  AcceptButton set it to  none
