Dim i As Integer = r("动力得分合计") / (r("动力得分合计") + r("阻力得分合计")) *1000
Dim i1 As Integer = r("阻力得分合计") / (r("动力得分合计") + r("阻力得分合计")) *1000
Dim p As WinForm.Painter = e.Form.Controls("Painter1")

g1.DrawString(msg1,fnt1,Brushes.red,50,190)
p1.Repaint()

绘画之前，要先把Painter的宽高设置成最大，然后绘画，然后设置回适合你页面的大小。
如代码
Dim p As WinForm.Painter = e.Form.Controls("Painter1")
p.dock = 0
p.width = 10000
Dim g As Graphics = p.Graphics
g.DrawLine(Pens.Red,30,0,30,60)
g.DrawLine(Pens.Red,0,30,60,30)
p.Repaint()
