VBA生成流程图的代码

以下是使用VBA生成流程图的代码示例：

Sub CreateFlowchart()

    Dim shp As Shape
    Dim x As Integer, y As Integer
    Dim shpWidth As Double, shpHeight As Double
    
    '设置画布大小
    ActiveSheet.Shapes.AddShape(msoShapeRectangle, 10, 10, 600, 400).Select
    
    '添加开始节点
    Set shp = ActiveSheet.Shapes.AddShape(msoShapeFlowchartTerminator, 50, 50, 100, 50)
    shp.TextFrame2.TextRange.Text = "Start"
    
    '添加第一个流程节点
    x = shp.Left + shp.Width + 50
    y = shp.Top
    Set shp = ActiveSheet.Shapes.AddShape(msoShapeFlowchartProcess, x, y, 100, 50)
    shp.TextFrame2.TextRange.Text = "Step 1"
    
    '连接开始节点和第一个流程节点
    Set shp = ActiveSheet.Shapes.AddConnector(msoConnectorStraight, shp.Left, shp.Top + shp.Height / 2, _
                                               shp.Left - 25, shp.Top + shp.Height / 2)
    shp.ConnectorFormat.EndConnectedShape = ActiveSheet.Shapes(2)
    shp.ConnectorFormat.EndConnectionSite = 1
    
    '添加第二个流程节点
    x = shp.Left
    y = shp.Top + shp.Height + 50
    Set shp = ActiveSheet.Shapes.AddShape(msoShapeFlowchartProcess, x, y, 100, 50)
    shp.TextFrame2.TextRange.Text = "Step 2"
    
    '连接第一个流程节点和第二个流程节点
    Set shp = ActiveSheet.Shapes.AddConnector(msoConnectorStraight, shp.Left + shp.Width / 2, shp.Top, _
                                               shp.Left + shp.Width / 2, shp.Top - 25)
    shp.ConnectorFormat.BeginConnectedShape = ActiveSheet.Shapes(3)
    shp.ConnectorFormat.BeginConnectionSite = 1
    
    '添加结束节点
    x = shp.Left + shp.Width + 50
    y = shp.Top
    Set shp = ActiveSheet.Shapes.AddShape(msoShapeFlowchartTerminator, x, y, 100, 50)
    shp.TextFrame2.TextRange.Text = "End"
    
    '连接第二个流程节点和结束节点
    Set shp = ActiveSheet.Shapes.AddConnector(msoConnectorStraight, shp.Left, shp.Top + shp.Height / 2, _
                                               shp.Left - 25, shp.Top + shp.Height / 2)
    shp.ConnectorFormat.BeginConnectedShape = ActiveSheet.Shapes(4)
    shp.ConnectorFormat.BeginConnectionSite = 1
    
End Sub

该代码演示了如何使用VBA在Excel中生成简单的流程图。首先，我们创建一个矩形作为画布，并添加开始节点。然后，我们添加两个流程节点，并使用连接器将它们连接起来。最后，我们添加结束节点，并使用连接器将最后一个流程节点连接到结束节点。

在实际使用中，您可以根据需要修改形状和位置，并添加更多的节点和连接器来创建更复杂的流程图。
