Let arrow keys work on WebBrowser Control & catch Esc, F11, & F5 (Fullscreen/Refresh)

[DTeCH]

Hello all :)


A strange feature of the MS WebBrowser Control showed it's head, & I tried figuring it out on my own, but it's stressful enough already without me having to go another week trying to make it work.


My problem is, I made a Win Forms app that loads a site's Flash game into it (many servers, & all live players). Now, when I load it up, it works fine... except it's not playable because the arrow keys are REQUIRED, but not working, & no matter how many times you press them, NOTHING happens in the game.

I have the following to catch the Esc, F11, & F5 keys:

    Private Sub AxWebBrowser1_PreviewKeyDown(sender As Object, e As System.Windows.Forms.PreviewKeyDownEventArgs) Handles AxWebBrowser1.PreviewKeyDown
        F11_Pressed = True
 
        'Arrow Keys (Up, Down, Left, & Right)
        If (e.KeyCode = 37 Or e.KeyCode = 38 Or e.KeyCode = 39 Or e.KeyCode = 40) = True Then Exit Sub
        Try
            'F11, or Esc key (Exit FullScreen)
            If Me.WindowState = FormWindowState.Maximized And (e.KeyCode = 122 Or e.KeyCode = 27) Then 
 
                Me.WindowState = FormWindowState.Normal
                Me.Width = Me_Width
                Me.Height = Me_Height
                Me.ControlBox = True
                StatusStrip1.Visible = True
                Me.FormBorderStyle = 4
                MenuStrip1.Visible = True
                Me.CenterToScreen()
 
            'F11 key (FullScreen)
            ElseIf Me.WindowState = FormWindowState.Normal And e.KeyCode = 122 Then
 
                Me_Width = Me.Width
                Me_Height = Me.Height
                Me.WindowState = FormWindowState.Maximized
                Me.ControlBox = False
                StatusStrip1.Visible = False
                Me.FormBorderStyle = 0
                MenuStrip1.Visible = False
 
            'F5 key (Refresh)
            ElseIf e.KeyCode = 116 Then
 
                Application.DoEvents()
                AxWebBrowser1.Refresh()
 
            Else
 
            End If
        Catch ex As Exception
 
        End Try
    End Sub
 
 

They work as expected, but the Arrow keys are not being received/handled by the WebBrowser control... although it does send them in the PreviewKeyDown event. The WebBrowser control is just ignoring their actions, yet everything else works just fine.


I DO NOT want to mess with the DOM of the page (don't see why we even need to :)), or other things because that WILL get the user banned.




UPDATE:

I figured it out guys.

I changed the above code from:

 
        'Arrow Keys (Up, Down, Left, & Right)
        If (e.KeyCode = 37 Or e.KeyCode = 38 Or e.KeyCode = 39 Or e.KeyCode = 40) = True Then Exit Sub
 
 

To:

 
        'Arrow Keys (Up, Down, Left, & Right)
        If (e.KeyCode = 37 Or e.KeyCode = 38 Or e.KeyCode = 39 Or e.KeyCode = 40) = True Then
            e.IsInputKey = True
            Exit Sub
        End If
 
 

It did the trick :)
