    Not to sure what kind of thing you want to draw.
    But I think you might want to take look of these API
    Private Declare Function StretchBlt Lib "gdi32" (ByVal hdc As Long, ByVal X As Long, ByVal Y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, ByVal nSrcWidth As Long, ByVal nSrcHeight As Long, ByVal dwRop As Long) As Long
Private Declare Function BitBlt Lib "gdi32" (ByVal hDestDC As Long, ByVal X As Long, ByVal Y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, ByVal dwRop As Long) As Long

    They can be used with picture box

    Hope this helps

    thanks for that il look into it basically its computers that have wires running to a switch and they are connected to a server so if the person changes the port in which the wire goes the line redraws itself but the switch is a picture so obviously you would need to make cordinates on the diagram = to numbers in the access database
