Problem with MouseDown on PictureBox

[opus]

Hi,
I've got a weird problem with the mousedown event on a picturebox.
I'm using the mouse to draw a line on the picturebox while the mousebutton is pressed.
Im saving the startposition (x,y) at mousedown and use the x,y at mousemove to draw the line.
That works fine.
If I start outside this picturebox with mousepressed and move into the box, nothing is shown, so far so good.
But If I'm start anywhere on the menu (mousedown over menu), the line is printed starting
at an old startposition as soon as I move onto the box.
?????????????????????
Does anybody have a clue on that?

It appears as though your app, has mistaken the menu for the picture box. Interesting.

Can you clear the (x, y) coordinates on the mouse down click event for the menu? Or Clear it on the mouse down <> Picturebox?

Post your code up. As Lee M suggested, maybe you're not clearing it, or if you are, it's not in the right event.

Try the following.

Private px As Single
Private py As Single
Private InBox As Boolean

Private Sub Picture1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If Button = 1 Then
        px = X
        py = Y
        InBox = True
    End If
End Sub

Private Sub Picture1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    If InBox = True Then
        If Button = 1 Then
            Picture1.Line (px, py)-(X, Y)
            px = X
            py = Y
        End If
    End If
End Sub

Private Sub Picture1_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
    InBox = False
End Sub

OK, here's the code:
Karte is the PictureBox
BearDistLine is a LineObject

Private Sub Karte_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    BearDistLine.X1 = X
    BearDistLine.Y1 = Y
End Sub
Private Sub Karte_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    BearDistLine.X2 = X
    BearDistLine.Y2 = Y
    BearDistLine.Visible = True
End Sub

Did my above code work for you?
