Loop A Listbox And Grab Text Value If Each Item?
Oct 29, 2009
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.
For i = 0 To Me.lstbxEmailListR.Items.Count - 1
Looking for a line of code that I can use to set a string to the listbox text
next
I don't need to use a listbox, But I figured it was easy to use to grab the email addresses from my DB.

I've been searching round Google for a soltuion for this problem for awhile now, though I have not yet found anything useful.I'm in the process in making a program that makes a list of all the computers on a network. All fo the values are saved in a Listview.
What I need is a way to selected something in the Listview, and it to be added to another value (for example, a textbox)I did find one solution, though this added this to every value "ListviewItem: [ITEM]" while instead of that, I just want the item.

In 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]....

a dialogue box to have the user open a file they wish. I'm trying to open a specific file when a listbox item is selected and I have that down but I'm running into the problem of needing to have "" in the display which is impossible from what I can tell in the code. I just need to know what goes in the quotes which will open the file. Also lets say the text file was 'supportdoc1.rtf' and was located in a folder inside of the program folder called 'SupportDocuments' would the path be "SupportDocumentssupportdoc1.rtf" [Code]

I'm creating an editable ListBox control, where the user can double-click an item to edit it. When double-clicked, I simply overlay a TextBox over the item, so the user can change the text and then commit it by pressing Enter or leaving the TextBox. The 'commit' is simply this:[code]where 'editingIndex' is the index of the item being edited, and 'textBox' is the TextBox object.If the ListBox contains strings, this works just fine. The item being edited is replaced by the textbox Text string.However, if the ListBox contains some other object (let's say a custom class), this is a problem! It still "works", in that it still sets the text of the item, but the item is no longer an instance of that custom class! It is now a String, and all other information about the item is lost. So, I really want to let the user be able to change the text representation of ANY object, without replacing the object with a string. Obviously, I cannot know how the object displays its text (well, by the ToString function of course, but I cannot know what the ToString function returns).Now, I am having a few ideas how to approach this, but none really work the way I want. I am pretty sure that I'm going to have to provide some kind of event that the user has to handle. I'm thinking something like this:
- When the item edit is committed, an event is raised
- This event contains the Item being edited (as an object, the user has to cast it himself), and the new text of the item.-
- The user handles this event, and assigns the new text to the correct property.
For the Person class, this could look something like this.My ListBox should raise this event, and assign the new item like this.[code]I think this should work (although I haven't tested it), but there's one problem with this approach:When the items are just strings, the user still needs to implement this event handler, while he shouldn't have to (I can simply assign the new text string to the item). So, if the user is simply using strings, he still needs to do this for every instance of my listbox:[code]So what I'm really looking for is a way so that I can implement the default behavior (for String items), and still allow the user to override this behavior if he is not using strings.I may be overlookihe obvious solution here, but I can't figure it out... Overriding is done when you inherit a class, but the user isn't going to inherit my custom listbox (well he CAN, but he shouldn't have to). He is just going to handle the event. And if he doesn't handle the event, my listbox uses the default implementation.

How to display text in a rich text box when an item is selected in a listbox. Here's a snippet of my
Private Sub radGunsNRoses_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles radGunsNRoses.Click
'Declares songs into variables
Dim strSong1 As String = "1. Sweet Child O' Mine"
Dim strSong2 As String = "2. Novemeber Rain"
Dim strSong3 As Integer = "3. Welcome to the Jungle"
'Band Picture

What I really want is that when radGunsNRoses is checked, the listbox displays the songs and when one is clicked, it shows the song's lyrics in the ritfSongs. Same thing goes for radACDC but the songs are different and the lyrics.
