Private Function GetNextKey() As String
Dim sNewKey As String
Dim iHold As Integer
Dim i As Integer
On Error GoTo myerr
iHold = Val(TreeView1.Nodes(1).Key)
For i = 1 To TreeView1.Nodes.Count
If Val(TreeView1.Nodes(i).Key) > iHold Then
iHold = Val(TreeView1.Nodes(i).Key)
End If
Next
iHold = iHold + 1
sNewKey = CStr(iHold) & "_"
GetNextKey = sNewKey
Exit Function

请问playyuer(女㊣爱)斑竹
为什么运行到下面时提示出错：对象With块未定义
TreeView1.Nodes.Add TreeView1.DropHighlight.Key, tvwChild, GetNextKey() & ListView1.SelectedItem.Text, ListView1.SelectedItem.Text
这是为什么
