Sort Items For A TreeView?
Sep 28, 2010
I am trying to sort a treeview, base nodes, which is the first base set you see before you click any + sign's I am trying to sort by alphabetical order, but, for the nodes inside each + view of the tree's I want to sort by number order, the number is currently set to the tag as text version of the number. Anyways, for the nodes in the + view's I need it to be able to skip over numbers if not every number in sequential order is there, so if number 4 is missing for example, still sort 1,2,3,5,6. My full code is pretty big but just retrieving items to display is random & I just add items as they come in, now they don't come fast or even when your not expecting new things to appear so it should not matter how it works really as it wont be updating as they are using the treeview.

I have a treeview in my program that lists all the folders and files in my TV Video collection. The tree lists as follows:
TV Series
|___SeriesName
|___SeasonNumber
|___EpisodeName
The problem I am having is that the SeasonNumber node does not sort 'properly' as I would like it.
It sorts like:
Season1
Season10
Season2 etc.
Instead of:
Season1
Season2...
Season9
Season10 etc.
I have tried this:
Private Sub scanFilesList()
Dim sfilenames() As String = System.IO.Directory.GetFiles(folderPath)
For Each strFileName As String In sfilenames
strFileName = GetFileName(strFileName)
tvVideoList.Nodes(n).Nodes.Add(vGroup, strFileName, 2, 2)
[Code] .....
As I understand it, this is supposed to sort ascending but it doesn't seem to change anything. I really only need to get the grandchild node sorted 'properly'.

Drag treeview named TreeView1, textbox named TextBox1,button named Button1.I m adding nodes programmatically. Select the node,Enter text in TextBox1 & then click on Button1 to add the node.Mine code is doing this, I want that when the user add nodes it automatically sorts.

I add strings (items) dynamically to a ToolStripItemCollection by:
Dim onClickHandler As System.EventHandler = New System.EventHandler(AddressOf Symbol_Click)
Dim item As New ToolStripMenuItem(newSymbol, Nothing, onClickHandler)
SomeToolStripMenuItem.DropDownItems.Add(item)
So the items are not added in one go, but one-by-one based on external triggers throughout the program session. I would like to sort the drop-down-list every time I add a new item. What are my options to achieve that?

Dim sortformat As String = "{0,-10}{1,12}"
Dim w As String
Dim y As String
For x = 0 To 7

I have a question about efficient implementation. Lets say I have two arrays:
One array is all possible items in a house: Table, Chair, TV, Fireplace, Bed
The other is an array of items in a particular house: Table, TV, Bed
I also have two list boxes:
1. listbox for items in the house - the "HAS" list box
2. listbox items not in the house - the "NEEDS" list box
I need to list the items already in the house in the "HAS" list box as well as the items that are NOT in the house in the "NEEDS" list box. It seems to me that nested "For each" loops would be a start to solving this problem but I am not exactly sure which case needs to be nested.

Let me preface this by saying that I'm very much a novice coder. I'm currently working on a small project to practice with Visual Basic and have experienced some issues during my save and load process using text files. I think I can solve the issue by changing the way my text file is initially saved. I want to see if I can sort the items and change the order in which they are written to the text file based of the value in one of the lines.[code]....

How would one code a button so upon cliking it items in listbox would sort either ascending or descending (depends on the button clicked). It mustn't be done with built-in Sort() but with a for loop for example. Tried to pseudo-code the solution to the problem, went as far as "store each listbox item in an array with a for loop".

I know that I can use treeview.nodes.find() but that will find the exact text so how would I search a treeview to find like items?
I have come close but this only searches the parents, never the children. Would I have to do a double search, start at parent and then get all nodes in parent?[code]...

If Form1.ListBox1.Items.Count = 0 Then
Else
Dim classSS3 As New StringSift3
Dim ReturnVal As Single

I am writing an application using Visual Basic Express 2008 and I need the right and the left mouse click to both act like the left mouse click. That is the right mouse click should not display a menu of any sort and be able to select items just as the left mouse click.

I have a listview control that I have a multitude of files displayed, in addition there are 6 columns in the listview that shows information about the file in question.
I have gotten this far, but my question is this: how do I allow the user to sort the listview by clicking on the column headers. Like one can do in list view in a Windows window?

I am making some kind of calendar where I can add tasks, so I can easily organise my tasks. For it to complete, I have 3 things I can't figure out how to do it:
1. When I launch the program, I want the items in my listbox to be sorted alphabeticly.
2. I want to save the items in the listbox, so if I close the program and reopen it the items are still saved in the listbox.
3. The items in the listbox all start with a date, fe. "13-4" for today. If that date already passed I want that item to be deleted.
