The following code is used when a tree node is being selected, then the child of that node will be printed.

and now, I just want to print those node automatically but not click the buttom lots of time. Thanks for your help^^

Dim show As Boolean = True
Dim no As Integer = 0
Dim i As Integer = 1


If (tvwLanguages.SelectedNode Is Nothing) Then
MsgBox("Please select a node to display!")
End If

If (tvwLanguages.SelectedNode.Checked = True) Then
MsgBox("Generation has been added!")
GoTo Finish
End If


While (displayArray(no, 0) <> Nothing)
show = StrComp("TreeNode: " + displayArray(no, 0), tvwLanguages.SelectedNode.ToString)

If (show = False) Then
tvwLanguages.SelectedNode.Checked = True
GoTo Print
End If

no = no + 1
End While


Print: While (displayArray(no, i) <> Nothing)

tvwLanguages.SelectedNode.Nodes.Add(displayArray(no, i))
i = i + 1

End While

tvwLanguages.SelectedNode.Expand()
Finish:
