How can I get an item of a specified index form listbox in a messagebox without selecting any item in listbox.
View 1 RepliesIn simple terms, I want to compare the value of a databound listbox display member with another string. However; I need to convert the listbox databound items to an array first as I may have to do 1,000's of comparisons on this.
I have a databound listbox from a sql server table that populates fine. I'm trying to retrieve the display value of a listbox item without selecting the item. My goal is to compare items in listbox1 with items in listbox2 and if item is in listbox1 matches an item I want to load into Listbox2, then I do not add the item to Listbox2. Listbox 2 is not databound but contents I'm loading come from a datatable.
So, I iterate through the items in listbox2's datatable but as I'm adding the items from the datatable to the listbox2, I check if the item exists in listbox1. The data that is being compared is the Displaymember of Listbox1 and a string value I want to manually load into listbox2.[code]....
I'm having a small hiccup in the following code. Basically what I have going on is a play button that will play the selected item in the listbox and once the button is clicked then the next item in the list is highlighted and waiting. This works exactly like I want it but the only issue is when it gets to the last item in the list it want play it.
Private Sub ButtonPlay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonPlay.Click

First of all, I'm a somewhat-experienced VB3 Developer, and I'm trying to convert a VB3 app to VB.NET.I got the programming guide (http:url....) by searching the web.The problem I'm having is the syntax for .NET is way different than VB3, and that's OK, but finding the correct syntax is very difficult.I'm trying to eliminate duplicates in a ListBox:
When I access the Programing guide, I see that:
ListBox.SelectedIndex Property
Gets or sets the zero-based index of the currently selected item in a ListBox.I also have Murach's and Stephen's manuals, and they say the same thing.Visual Studio converted The old .ListIndex to a VB6 Function:
If VB6.GetItemString(PlayList_ListBox, I) = VB6.GetItemString(PlayList_ListBox, I + 1) Then
This is Try #1. It generates: VB6 is not declared. It may be inaccessible due to its protection level.Then I read that VB6 is only for converting old code.So then I tried SelectedIndex:

I have a listbox that contains a bunch of email addresses from a SQL database.I have some code that I use to send an email with some values from my app.How can I loop through my list box and grab the email address to use as my mail.to.add(emailaddress) string I have this and it loops twice because Thats how many addresses I have in my test listbox.

I'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?

View 13 RepliesI've been trying to add to a listbox item from a different thread (thread 2) than the thread in which the form/listbox was created (thread 1).
When I check ListBoxItem.InvokeRequired from within thread 2 it is always false when ApartmentState.STA is set. When set to MTA I get an error. Thread 2 is a unique thread with different ID from thread 1.
What is frustrating is that at one point it was working fine, and then I changed some of the structure of the project and it has now stopped working (and I don't know which change caused this! It was a while ago).

i have a list box which is populated with the sub folders from a user selected folder, so the listbox item count varies from 2 item to 1000 items etc.The list box code i use to do this is:
Dim lb1s As String = Form1.Folder.SelectedPath
Dim di As New IO.DirectoryInfo(lb1s)
Dim mydirInfoArray As IO.DirectoryInfo() = di.GetDirectories
Im trying to make a feature were on a button click the app will create 1 folder for every item on the listbox (named after the list box item)So if theres 3 items on the list box for example:
001
002
band 3
[code]....
And when the user presses the button, the app will create 3 dupe folders (Only the folders, not the contents) in a user selected directory using the same names, ive been tinkering for a little while but cant seem to figure out a way to implement this.
this is going to be hard to explain but ill try. Question 1. Ok i have a list box with a few items, What i want for this example is to click a button and it will start on the first item and do: MsgBox ("this is item blah blah blah") then after that it will go to the next item and do the same and then the next and so on untill all have been done. The "blah blah" should be the item so if item was to say "hello" then the msgbox would say "this item is hello" I know this would be a lot of msgboxes to close, like if 50 items then thats 50 msgboxes to close, this is just for the example.
Question 2. Ok this is where ive tryed to learn but find it really hard (multithreading) Im wanting all to be multithreaded so all work at the same time, ive tryed a few times but the only way i see it is having a **** load of subs, like if i want it to use 10 threads then ill have to add the same code 10 times or somet, im not sure.
i have attempted all this and failed big time as my way was to get the first item and use that then remove it from the listbox BUT... with it being quite fast the 2nd 1 and 3rd 1 used the same item befor it was removed and to be honest i dont really want them removed. so my attempts took like 2-3 days that was a waste of time really. I Know this is a lot to ask but im in real need of it and these 2 things have driven me half mad.
