下面是一段测试

  1. Sub test()
  2.     Dim ss As New TlsSel
  3.     ss.Init
  4.     ss.SetFilter 0, "Insert", 2, "1"
  5.     ss.Selectobject acSelectionSetAll
  6.     MsgBox ss.Count

    Dim nCount As Integer
    nCount = (UBound(Filter) + 1) / 2 - 1
   
    Dim ft() As Integer, fd()
    ReDim ft(nCount), fd(nCount)
   
    For i = 0 To nCount
        n = i * 2
        ft(i) = Filter(n)
        fd(i) = Filter(n + 1)
    Next i
   
    TlsFt = ft
    TlsFd = fd

End Sub
这个函数不太明白,为什么nCount = (UBound(Filter) + 1) / 2 - 1??

(UBound(Filter) + 1)是Filter数组的元素个数
设置过滤器前先在命令行键入"(entget(car(entsel)))",看看对应实体的DXF组码

doc1.CopyObjects ToArray(acadselect)


Public Function ToArray(ByVal osel As AcadSelectionSet)
'转化选择集为对象数组输出
On Error Resume Next

    Dim i
    Dim objs() As AcadEntity
    Dim nCount As Integer

    nCount = osel.Count - 1
    ReDim objs(nCount)

    For i = 0 To nCount
        Set objs(i) = osel(i)
    Next i

    ToArray = objs
End Function

toarry拿出来放到其它的程序中调用时,执行到toarry=objs时就出错,提示“对象不在数据库中”是怎么回事?
