Hello everybody,

I am a little bit stuck on the following task:

I have a project with several Forms.
I need to get the "Enter" key from several forms but this does not work.
Only in the first form of the project it works properly.

What I have tried:

I use the following code to get in Enter in the first form:

Private Sub Start_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown
  Select Case e.KeyCode
  Case Keys.Enter
 
  End Select

End Sub

Key presses are sent to the Window (Form) that currently has the focus.

But other keyboard inputs like normal characters e.g. a,b,c or 1,2,3 are sent
correctly on other forms. Only the enter does not work.

No - key presses are sent to the window (form) that currently has the focus. How would you know Enter has not been sent with the code that you have posted - you're not even sending a message to the debug window (debug.print("enter pressed")).
Try putting a break point in there and examining the KeyCode that is sent.

Sorry, but I forgot to comment the code above. It was only an incomplete snippet.
I tried to analyse the keyboarddata by writing it into the debug window.
Something like:
Private Sub Start_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown
Debug.Print(CStr(e.KeyCode))
End Sub

It is working fine on form1. I get an output for normal characters and specialkeys like Enter. But when I open form2, it does not work. In form2 I get the output for 1,2,3 etc. but not for Enter.

Solution 1

I found a solution:

In the load_event a usercontrol had to be selected.
In my case it was the textbox which had to be selected.

Private Sub form1_Load(sender As Object, e As EventArgs) Handles Me.Load
    textbox1.Select()
End Sub

Now everything is working fine.

That is why my comment said "Key presses are sent to the Window (Form) that currently has the focus.". The key being the word "Window", as every control on a Form is a Window.
