Dim TCS As CSDN.TCS
Dim App As CSDN.Tcs_Application
Dim Rw As Integer
Sub Test()
Call Login
Dim rNodes As CSDN.RootDbNodes
Set rNodes = App.Parameters.DbTree.RootNodes
Rw = 1
For I = 1 To rNodes.Count
Cells(Rw, 1).Value = rNodes.Item(I - 1).Text
Call GetNode(rNodes.Item(I - 1), 1)
Rw = Rw + 1
Next
End Sub
Sub GetNode(Node As DbNode, Cl As Integer)
For I = 1 To Node.Count
Rw = Rw + 1
Cells(Rw, Cl + 1).Value = Node.Item(I - 1).Text
Call GetNode(Node.Item(I - 1), Cl + 1)
Next
End Sub
Sub Login()
If TCS Is Nothing Then Set TCS = CreateObject("CSDN.TCS")
If App Is Nothing Then Set App = TCS.Login
