GetBlockAttributeValue 方法 (ActiveX) 
获取具有属性定义 ID 的块内容中的属性值。 支持的平台:仅限 Windows 签名 - MLeaderVBA: RetVal = object.GetBlockAttributeValue(attdefId) 
 签名 - 表格VBA: RetVal = object.GetBlockAttributeValue(row, col, attdefId) 
 返回值 (RetVal)类型:字符串 属性值。 言论没有其他评论。 例子VBA: Sub Example_Blockttribute()
    ' This example creates an MLeader object and gets and sets values for
    ' the block attribute type.
    Dim points(0 To 5) As Double
    points(0) = 0: points(1) = 4: points(2) = 0
    points(3) = 1.5: points(4) = 5: points(5) = 0
    Dim i As Long
    Dim oML As AcadMLeader
    Set oML = ThisDrawing.ModelSpace.AddMLeader(points, i)
    
    oML.ContentType = acBlockContent
    oML.ContentBlockType = acBlockBox
    Dim sBlock As String
    sBlock = oML.ContentBlockName
    Dim o As AcadEntity
    For Each o In ThisDrawing.Blocks(sBlock)
        If o.ObjectName = "AcDbAttributeDefinition" Then
            oML.SetBlockAttributeValue o.ObjectID, "123"
            MsgBox oML.GetBlockAttributeValue(o.ObjectID)
        End If
    Next o
    
    Update
    ZoomExtents
End Sub
