VBA：

object.UpperRightCorner

对象

类型：视口

此属性应用于的对象。

属性值

只读：是的

类型：变体（双精度的两个元素数组）

言论

and 属性表示视口在显示器上的图形位置。这些属性定义如下：LowerLeftCornerUpperRightCorner

视口 1— = （0， .5）， = （.5， 1）LowerLeftCornerUpperRightCorner

视口 2— = （.5， .5）， = （1， 1）LowerLeftCornerUpperRightCorner

视口 3— = （0， 0）， = （.5， .5）LowerLeftCornerUpperRightCorner

视口 4— = （.5， 0）， = （1， .5）LowerLeftCornerUpperRightCorner

例子

VBA：

Sub Example_UpperRightCorner()
    ' This example creates a new viewport and makes it active.
    ' Then it splits the viewport into 4 windows.
    ' It then takes finds the upper right corner of each of the
    ' windows.
    Dim newViewport As AcadViewport
       
    ' Create a new viewport and make it active
    Set newViewport = ThisDrawing.Viewports.Add("TESTVIEWPORT")
    ThisDrawing.ActiveViewport = newViewport
    
    ' Split the viewport in 4 windows
    newViewport.Split acViewport4
    
    ' Make the newly split viewport active
    ThisDrawing.ActiveViewport = newViewport
    
    ' Iterate through the viewports. For each viewport,
    ' make that viewport active and display the coordinates
    ' of the upper right corner.
    Dim entry As AcadViewport
    Dim UpperRight As Variant
    For Each entry In ThisDrawing.Viewports
        entry.GridOn = True
        ThisDrawing.ActiveViewport = entry
        UpperRight = entry.UpperRightCorner
        MsgBox "The upper right corner of this viewport is " & UpperRight(0) & ", " & UpperRight(1), , "UpperRightCorner Example"
        entry.GridOn = False
    Next
End Sub
