Well, I got the shot to display, but I cant get the thing to move Good greif, lol

Here's my shot structure, the bullet fires at the angle of the ship:

Public Structure Shot
        Dim XPos As Int32
        Dim YPos As Int32
        Dim picbox As PictureBox
        Dim speed As Int32
        Dim distance As Int32
        Dim angle As Int32
        Dim damage As Single
        Sub UpdateShot()
            Dim X, Y As Int32
 
            X = -Math.Sin(angle * Math.PI / 180.0) * 3
            Y = -Math.Cos(angle * Math.PI / 180.0) * 3
 
            XPos = XPos + X
            YPos = YPos + Y
            picbox.Location() = New Point(XPos, YPos)
            'Add your collision checking code here
        End Sub
    End Structure

Here's where the shot is created (mouse click):

x.picbox = New PictureBox
                x.picbox.Image = pctShot.Image
                x.picbox.SizeMode = PictureBoxSizeMode.AutoSize
                'x.picbox.Location = New Point(500, 500)
                x.XPos = myShip.picbox.Location.X + (myShip.picbox.Width / 2)
                x.YPos = myShip.picbox.Location.Y + (myShip.picbox.Height / 2)
                x.speed = 3
                x.distance = 500
                x.picbox.Visible = True
                x.angle = myShip.angle
                Controls.Add(x.picbox)
                shotList.Add(x)

Background worker shot dowork:

For i = 1 To 2
            bwShot.ReportProgress(i)
            If i = 2 Then i = 1
            If bwShot.CancellationPending = True Then
                Exit For
            End If
            System.Threading.Thread.Sleep(30)
        Next

Background worker shot progress changed:

Dim y As Shot
        For Each y In shotList
            y.UpdateShot()
        Next

Now I can tell that it is making the shot because it's displaying it (where the ship is), but it's not moving. Through use of msgbox's I've determined that it's getting inside the updateshot routine, but nothing is changing. the updateshot code is basically the same code for the ships movement, only in this case the angle is constant (set to what angle the ship was at fireing). Any thoughts would be appreciated, I'm probably missing somthign obvious.
