strange problem For Each loop in Treeview
Correcting a simple typo solved this problem:
If nodChild.Parent = nodcurrent Then should be: If nodChild.Parent Is nodcurrent Then RBS "RB Smissaert" wrote in message ... Use a recursive Sub to traverse the nodes of a Treeview control from top to bottom. Noticed that there is a problem if 2 nodes in the Treeview have the same text. Rather than ending at the lowest node the sub returns to the higher node with the same text and the Sub doesn't exit. This are the 2 Subs that demonstrate it: Sub Tester(ByRef nodcurrent As Node, _ ByVal intdepth As Integer) Dim nodChild As Node If nodcurrent.Children 0 Then For Each nodChild In MainForm.TreeView1.Nodes If Not nodChild.Parent Is Nothing Then If nodChild.Parent = nodcurrent Then MsgBox nodChild.Text Call Tester(nodChild, (intdepth + 1)) End If End If Next nodChild End If End Sub Sub DoTester() Tester MainForm.TreeView1.Nodes(1), 0 End Sub Is this a known bug, or am I doing something wrong? One way to solve this problem is to fill an array with the indeces of the visited nodes and make sure the same node doesn't get visited twice, but perhaps there is a better solution for this. Thanks for any advice. RBS |
