    Resolved [RESOLVED] Adding nodes to a TreeView

    I need to be able to add nodes to a treeview at runtime but I dont know how many I need to add before I run the program. Here is what happends, I read a txtfile then I certain info from that textfile and then I need to add the info into a treeview. I have the first part working fine but im not sure how to add the strings to a treeview here is the code im using now
    vb Code:
    1. Dim root1 As TreeNode = New TreeNode("root1Text")
    2.         Dim root2 As TreeNode = New TreeNode("root2Text")
    3.         Dim sub1 As TreeNode = New TreeNode("sub1Text")
    4.         Dim sub2 As TreeNode = New TreeNode("sub2Text")
    5.         TVOpen.Nodes.Add(root1)
    6.         TVOpen.Nodes.Add(root2)
    7.         root1.Nodes.Add(sub1)
    8.         root1.Nodes.Add(sub2)

    That code works. What's the problem? You know how to add a string to a TreeView. Do you know how to read a text file? If so then you already know everything you need. Just loop through the lines of the text file and add each to the tree.

    Well it works but how would I loop through it so I dont have to make a million variables? At the moment it only adds 2 nodes, how would i add multiple nodes with differnt strings.

    Are you saying that you don't know how to loop through an array or collection of strings?

    That's a bit of a worry.
    vb Code:
    1. For Each str As String In myArrayOrCollection
    2.     'Use str here.
    3. Next str
