[求助]选择集问题

laoxie_198

我图形中有的图元包含如下的扩展数据
Dim datatype(0 To 7) As Integer
Dim data(0 To 7) As Variant
datatype(0) = 1001: data(0) = ""
datatype(1) = 1000: data(1) = jfh
datatype(2) = 1003: data(2) = "0"
datatype(3) = 1040: data(3) = 1.232
datatype(4) = 1041: data(4) = 100’此处有时候为100，有时候为0
datatype(5) = 1070: data(5) = jfid
datatype(6) = 1071: data(6) = zdh + 1
datatype(7) = 1042: data(7) = 10
ty.SetXData datatype, data
ThisDrawing.Application.Update

我想构建扩展数据里data(4) = 100的图元的选择集，可怎么总是出错呀？请高手指点
下面是我的代码
Sub pd()
On Error Resume Next
Dim p1(0 To 2) As Double
Dim p2(0 To 2) As Double
Dim fType, fData As Variant
'p1(0) = 100
'p1(1) = 100
'p1(2) = 0
'p2(0) = 500
'p2(1) = 500
'p2(2) = 0
Dim x, y As Double
Dim dh  As Long
fType(0) = 1041: fData(0) = 100
'ftype(1) = 2: fdata(1) = "界址圈"
'Call CreateSSetFilter(fType, fData, 1041, 100)
'tyxzj.Select acSelectionSetAll, , , fType, fData
Dim ggdxzj As AcadSelectionSet
If Not IsNull(ThisDrawing.SelectionSets.Item("jzq")) Then
 Set ggdxzj = ThisDrawing.SelectionSets.Item("jzq")
 ggdxzj.Delete
End If
Set ggdxzj = ThisDrawing.SelectionSets.Add("jzq")
ggdxzj.Select acSelectionSetAll, , , fType, fData
'ggdxzj.Select acSelectionSetWindow, p1, p2
'tyxzj.Select acSelectionSetAll, , , ftype, fdata
End Sub
