I just write the following code in the Treeview_MouseDown event:

Code:
Dim Px As Long
Dim Py As Long
If Button = vbRightButton Then
    GetCursorPos pt
    Px = ScaleX(pt.x, vbPixels, vbTwips)
    Py = ScaleY(pt.y, vbPixels, vbTwips) - 250

    PopupMenu mnuOPTION, vbPopupMenuLeftAlign, Px, Py
End If
When my form in Maximized mode, everything is fine, PopUpmenu just beside my mouse pointer. But if I resize my form then the problem come out and I can not set the PopUpmenu right beside my mouse pointer.

It is something wrong with my code? Does anyone have a better solution for the PopUpMenu?

Thanks,
Chris.C
