Get Selected Item Index Or A Sorted & Grouped List Relative To Item Source?
Feb 12, 2011I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.
What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.

As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?

Edit Item Or Subitem Values Of A Selected Listview Item?
May 19, 2009Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString

View 5 RepliesDelete Selected Listbox1 Item And Listbox2 Item With Same Value?
Mar 1, 2012I am making a password program that remembers what the password is for and what the password is. I have two listboxes: 'listbox1' for what the password is for, and 'listbox2' for the password. I also have a remove button. I would like it so when you press the remove button, the selected item in listbox1 is removed and the password in listbox2 is also deleted. The passwords are stored in two settings: what, and pw. The items that will be deleted will have the same value. By value i mean they will be the same number item. E.G. the 1st item, or the 3rd item in the list.

VS 2010 - List(Of ).Clear() - Load Several Lists Of Codes From A Database Depending On The Import Selected By The User
Dec 29, 2011When .Clear() is invoked, is the memory freed up that was allocated when all of the items were added? I need to load several lists of codes from a database depending on the import selected by the user. Each list of codes will be a List(Of String). My idea is that I will load only small strings into a List(Of String) along with a List(Of <class>) for the data I will be validating and manipulating. When I am done, I want all of the data from the Lists to be purged from memory. Will .Clear() take care of that or does the memory still remain allocated and have to be dumped by the OS once memory gets full? (And, incidentally, what causes the OS to decide which memory blocks to dump? FIFO concept?)
There are so many lists, I'm not sure if I just want them sitting in memory or not. Granted, the lists will just consist of a single string value for each code pulled from the database. So there won't be a ton of data, so maybe I could just load all the validation lists at the beginning of runtime and only worry about purging the data List since it will contain between 35-50 "fields" per record and there will be a couple thousand records each import that is run. I don't want my program to actually cause a hit in performance in the long run. I ultimately don't see a problem because I won't be running millions or even hundreds of thousands of records at once, but I just want to be sure.

Get Selected Item From A List?
Aug 3, 2010i have a sub that checks all drives on a computer;
Dim getInfo As System.IO.DriveInfo()
getInfo = System.IO.DriveInfo.GetDrives
For Each info As System.IO.DriveInfo In getInfo
TextBox1.Text = TextBox1.Text & info.Name & vbCrLf
Next
this shows all drives in textbox1. now if i select the drive i want, i can then check the free & total space with this sub;
Dim cdrive As System.IO.DriveInfo
cdrive = My.Computer.FileSystem.GetDriveInfo(TextBox1.SelectedText)
TextBox2.Text = TextBox1.SelectedText & " has " & cdrive.TotalSize / 1024 / 1024 / 1024 & "gb total space" & vbCrLf
TextBox2.Text = TextBox2.Text & "and " & cdrive.TotalFreeSpace / 1024 / 1024 / 1024 & "gb free space"
all this is good if i select the drive i want to check. but if i only click the drive, since no text is selected, the second sub does not work.is there a way to check at which index the cursor is, grab the item of the index, and pass it to the sub so i don't have to select the text itself?
