Question

i am designing a VB quiz game, it loops 20 questions

i tried to show the Form by
Form1.show
Form1.focus

in my testing platform, there may be unnecessary programs running. in production platform, it should be more clean. But the interrupt make me loss confidence. How can i make sure the form get focus? the program has few forms. Thanks a lot.

@WONG Tony , you could try to use the event LostFocus and method Control.Focus to keep the focus all the time.

Here is a code example you could refer to.

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load  
        Me.Focus()  
        AddHandler Me.LostFocus, AddressOf Form1_LostFocus  
    End Sub  
  
    Public Sub Form1_LostFocus(sender As Object, e As EventArgs)  
        Me.Focus()  
  
    End Sub
