用宏功能啊，然后把宏代码（vb6.0）转化为Vb.net代码，有一个关键问题，就是VBA中的枚举类型在Vb.net中不适用，比如.End(xlUp)更改为.End(3)就能运行，另外vb.net中运行Excel对象不一定在点后会出现智能提示（即使你引用后也一样）你只要确定有该方法或者属性，直接写就是了，生成或者调试都是可以通过的

1. 建一个默认的project
2. 放一个command button
3. 放一个 200x200 pixel 的 Picture box
加入如下代码：
Option Explicit
Public Sub DrawPiePiece(lColor As Long, fStart As Double, fEnd As
Double)
Const PI As Double = 3.14159265359
Const CircleEnd As Double = -2 * PI
Dim dStart As Double
Dim dEnd As Double
Picture1.FillColor = lColor
Picture1.FillStyle = 0
dStart = fStart * (CircleEnd / 100)
dEnd = fEnd * (CircleEnd / 100)
Picture1.Circle (100, 100), 60, , dStart, dEnd
End Sub
Private Sub Command1_Click()
Picture1.ScaleMode = vbPixels
Call DrawPiePiece(QBColor(1), 0.001, 36)
Call DrawPiePiece(QBColor(2), 36, 55)
Call DrawPiePiece(QBColor(3), 55, 75)
Call DrawPiePiece(QBColor(4), 75, 99.999)
End Sub
试一下吧
Dim MyGraphics As Graphics = Me.PictureBox1.CreateGraphics
Dim MyBrush As New SolidBrush(Color.Red)
Dim MyProportion As Single
Dim MyRect As New Rectangle
Dim MyPoint As New PointF
Dim R As Single
Const PI = 3.1415926
MyGraphics.Clear(Color.White)
Dim MyStartAngel As Double
Dim MySweepAngel As Double
R = Math.Min(Me.PictureBox1.Width, Me.PictureBox1.Height) / 2 - 15
MyPoint.X = Me.PictureBox1.Width / 2
MyPoint.Y = Me.PictureBox1.Height / 2
MyRect.X = MyPoint.X - R
MyRect.Y = MyPoint.Y - R
MyRect.Width = R * 2
MyRect.Height = R * 2
MyStartAngel = 0
MyProportion = Val(TextBox7.Text)
MySweepAngel = MyProportion * 360 / PI
MyBrush.Color = Color.Red
MyGraphics.FillPie(MyBrush, MyRect, MyStartAngel, MySweepAngel)
' MyStartAngel = MyStartAngel + MySweepAngel
MyProportion = 0.75
MySweepAngel = 360 * MyProportion
MyBrush.Color = Color.Blue
MyGraphics.FillPie(MyBrush, MyRect, MyStartAngel, MySweepAngel)
给你一个步骤吧.
设立一个圆心(即定一个点)
再按照用PI转角来画就行了.
最后加上你需要的颜色
