引言:今天的问题整理自mrexcel.com论坛,不难但可能会有部分人会感兴趣。
Q:我怎样使用VBA代码在两个单元格之间绘制一条直线?一个单元格命名为“start”,另一个单元格命名为“stop”,我想绘制一条红色的直线连接它们。如下图1所示。

A:很简单的代码。
先确定直线的起点和终点坐标,再绘制直接并添加颜色。代码如下:
Sub AddLine()
Dim l1 As Long
Dim l2 As Long
Dim r1 As Long
Dim r2 As Long
With ActiveSheet.Range("start")
l1 = .Left
l2 = .Top
End With
With ActiveSheet.Range("stop")
r1 = .Left
r2 = .Top
End With
With ActiveSheet.Shapes.AddLine(l1, l2, r1,r2).Line
.ForeColor.RGB = RGB(255, 0, 0)
End With
End Sub
如果直线的起点在单元格start的左下角,如下图2所示。

可以使用下面的代码:
Sub AddLine1()
Dim l1 As Long
Dim l2 As Long
Dim r1 As Long
Dim r2 As Long
With ActiveSheet.Range("start")
l1 = .Left
l2 = .Top .RowHeight
End With
With ActiveSheet.Range("stop")
r1 = .Left
r2 = .Top
End With
With ActiveSheet.Shapes.AddLine(l1, l2, r1,r2).Line
.ForeColor.RGB = RGB(255, 0, 0)
End With
End Sub
如果直线的起点在单元格start的右下角,如下图3所示。
图3
可以使用下面的代码:
Sub AddLine2()
Dim l1 As Long
Dim l2 As Long
Dim r1 As Long
Dim r2 As Long
With ActiveSheet.Range("start")
l1 = .Left .ColumnWidth * 6.5
l2 = .Top .RowHeight
End With
With ActiveSheet.Range("stop")
r1 = .Left
r2 = .Top
End With
With ActiveSheet.Shapes.AddLine(l1, l2, r1,r2).Line
.ForeColor.RGB = RGB(255, 0, 0)
End With
End Sub
可以调整代码中的数值“6.5”,以确定合适的起点位置。
