VB.NET help

Does anybody know how to capture more than one key press at a time?
Currently I am using this code:

Code: [Select]

    Private Sub Form1_KeyDown1(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
        If e.KeyCode = Keys.Up Then
            'do something
        ElseIf e.KeyCode = Keys.Down Then
            'do something
        ElseIf e.KeyCode = Keys.Left Then
            'do something
        ElseIf e.KeyCode = Keys.Right Then
            'do something
        End If
    End Sub
But this method only seems to capture on key press at a time. If I hold down two, only the last one is used.

Oh yeah, also, one more question: How can I set autoRedraw on? I think this was a property in VB5, but I can't find it in VB.NET!

Thanks

I'm not sure if they have an automatic way but this is what I usually do:

Code: [Select]

Dim mv_strKeysDown As String

    Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
        Dim str As String
        str = ChrW(e.KeyCode)
        If Not mv_strKeysDown Like "*" & str & "*" Then
            mv_strKeysDown &= str

        End If

        lbl.Text = mv_strKeysDown

    End Sub

    Private Sub Form1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyUp
        mv_strKeysDown = Replace(mv_strKeysDown, ChrW(e.KeyCode), "")
        lbl.Text = mv_strKeysDown

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        mv_strKeysDown = vbNullString

    End Sub

*Edit: I just tried that with the arrow keys and it doesn't work but if you used something other than chrw it probably would work...

I found another solution on the web: http://www.vb-helper.com/howto_detect_arrow_keys.html

And now my other question

Yeah, that's basicly the same thing except that you make it array based instead of string based. Same concept though.
