Getimage of control function problem....plz help...

hi guys, ive two custom controls, which are used to draw and edit etc...(like paint but customized....) i want to save their images with a single click....
So im using the Getimageofcontrol function to do it....
its code is below:::

Code:

---

Public Function GetImageOfControl(ByVal c As Control) As Image
        Dim rc As New Rectangle(c.PointToScreen(c.Location), c.Size)
        Dim i As Image = New Bitmap(rc.Width, rc.Height)
        Dim g As Graphics = Graphics.FromImage(i)
        g.CopyFromScreen(rc.Left, rc.Top, 0, 0, rc.Size)
        g.Dispose()
        Return i
        i.Dispose()
    End Function

---

and the code to call this function for saving the images is simply.. ...

Code:

---

GetImageOfControl(pboxd).Save("c:\78.jpg")
        GetImageOfControl2(pboxf).Save("c:\lp.jpg")

---

but the problem is that both the images have the same content....
