and another NEWBIE one ...

[alex_read]

can someone do the explanation as to why the left & right here work, but the up & down don't ???

Private Declare Function GetKeyState Lib "user32.dll" (ByVal nVirtKey As Long) As Integer

Private Sub Timer1_Timer()
    If GetKeyState(vbKeyLeft) And &H8000 Then Picture1.Left = Picture1.Left - 20
    If GetKeyState(vbKeyRight) And &H8000 Then Picture1.Left = Picture1.Left + 20
    If GetKeyState(vbKeyUp) And &H8000 Then Picture1.Left = Picture1.Top - 20
    If GetKeyState(vbKeyDown) And &H8000 Then Picture1.Left = Picture1.Top + 20
End Sub

Doesn't make sense to me. Thanks

I dunno why your code doesnt work.
But why dont you try this approach, its smoother by far !
Just give it a go and you'll see.

Option Explicit

Private keyUp As Boolean
Private keyDown As Boolean
Private keyLeft As Boolean
Private keyRight As Boolean
Private LastTick As Long

Private Declare Function GetTickCount Lib "kernel32" () As Long


Private Sub Form_KeyDown(KeyCode As Integer, Shift As Integer)
    Select Case KeyCode
        Case vbKeyLeft:
            keyLeft = True
            keyRight = False
        Case vbKeyRight:
            keyLeft = False
            keyRight = True
        Case vbKeyUp:
            keyUp = True
            keyDown = False
        Case vbKeyDown:
            keyUp = False
            keyDown = True
    End Select
End Sub

Private Sub Form_KeyUp(KeyCode As Integer, Shift As Integer)
    Select Case KeyCode
        Case vbKeyLeft:
            keyLeft = False
        Case vbKeyRight:
            keyRight = False
        Case vbKeyUp:
            keyUp = False
        Case vbKeyDown:
            keyDown = False
    End Select
End Sub

Private Sub RunLoop()
    Do
        DoEvents
        If ((GetTickCount - LastTick) > 50) Then
            LastTick = GetTickCount
            Select Case True
                Case keyUp:
                    Picture1.Top = Picture1.Top - 20
                Case keyDown:
                    Picture1.Top = Picture1.Top + 20
            End Select
            Select Case True
                Case keyLeft:
                    Picture1.Left = Picture1.Left - 20
                Case keyRight:
                    Picture1.Left = Picture1.Left + 20
            End Select
        End If
        DoEvents
    Loop
End Sub


Private Sub Form_Load()
    Me.Show
    RunLoop
End Sub

Private Sub Timer1_Timer()
    If GetKeyState(vbKeyLeft) And &H8000 Then Picture1.Left = Picture1.Left - 20
    If GetKeyState(vbKeyRight) And &H8000 Then Picture1.Left = Picture1.Left + 20
    If GetKeyState(vbKeyUp) And &H8000 Then Picture1.Left = Picture1.Top - 20
    If GetKeyState(vbKeyDown) And &H8000 Then Picture1.Left = Picture1.Top + 20
End Sub

I hope you'll notice the bug

[plenderj]

Ya know, I never even bothered checking if the code was dodgy when I tried it ...

[kedaman]

i didn't even try it alex code fullfills it purpose so i didn't bother rewrite it

[plenderj]

my approach owns
