I want to develop a tree view and list view form by using vb6, how to construct a tree view and list view form?
View 1 RepliesSo another first timer question.I have user entered data from a form that gets put into separate strings. On another form i want this data to populate a Tree view when the user presses a button "Add data". There will be only one stage of parents and child. oParent and oChild. The oParent string will only have like 5 items but the oChild will have like 30 and these will be repeated for each oParent. Not sure how populate this, i cam guessing with some sort of For Each i in oParent, add i or whatever, but not sure of the syntax.

Requesting help for this situation.
Is it possible and if so, how does one go about doing such a thing. I am loading a network directory in a treeview. Can the parent node be disabled, meaning it can't be selected, it's available for viewing only, but leave the child nodes selectable?

I'm looking for a way to create the treeview structure in memory with a classes, so I can loop through them, like with a collection and easily load the data into a treeview, listview, datagridview or simply work with the data in the background.
There's a treenode class that I could use, but I've noticed that when I have a lot of data in the nodes, it has a lot overhead when for example serializing, because it also saves the checked state, imageindex of the nodes and things like that, which I never need. The saved file is about 10 times bigger than the actual data, which is not acceptable.
