主题：帮忙看看这个代码

Dim tr As WinForm.TreeView = Forms("窗口1").Controls("TreeView1")
Dim nd As WinForm.TreeNode = tr.SelectedNode
Dim fts()As String
Dim n As Integer
Dim s As String
fts = nd.FullPath.Split("\")
Dim dr As DataRow
dr = DataTables("产品").AddNew()
dr("名称") = fts(fts.length-1)
For Each ft As String In fts
    s = s & left(nd.name,3*(n+1)) & "\"

n = n + 1
Next
dr("ID") =s.trim("\")

想将以上代码中，双击任意一个节点时，“自动增加行”的代码去掉不要了，其它的功能保持不变，
