I have a program in which I need the user to be able to import multiple image filenames into a listbox. Here is my

I have a string of filenames separated by commas that I want to add to a listbox. This is how I'm currently doing it:
vb.net
Dim FileNameArray() As String
myFileNames = tblOpenTemplate.Rows(0).Item("filenames").ToString
FileNameArray = myFileNames.Split(",")
For i As Integer = 0 To UBound(FileNameArray)
.ListBoxFileNames.Items.Add(FileNameArray(i).ToString)
Next i
But I've been reading about using:
vb.net
Dim FileNameArray As New List(Of String)
How to populate this with string of filenames?
I am trying to fill filenames from a folder into a listbox. Now what i want to achieve is that if in the folder there are 2 files with same name but different extension for example song.wmv and song.mp3 then i want to show only .mp3 filename in the listbox. This is how it works in VB6. PERFECT! How to make this code work in .net.
[Code]...
i have the following snippet of
For Each tempstring In SourceDataCollection
LineToFieldsTemp = Split(tempstring, ",")
LineStringWithoutFirstEntry = "" 'reset the linestring
For i = 1 To UBound(LineToFieldsTemp)
[code]....
essentially what i'm doing is to read through each item in a collection of comma separated variable strings. the first variable in each string is appended to a master filename and becomes the NEW filename to which the entire string will be appended. this is a way to split a CSV file into multiple files using the first variable in that string.
the trouble is that this is doing a LOT of writes to potentially a LOT of files, the IO is taking forever. is there a way to buffer this data until the end, then write it to a disk? be aware, the filenames and total number of files to be created is UNKNOWN at the begining of the loop. it just creates a new file each time a unique first column ID is discovered.
[code]I have one button to play all the stuff, but it needs the full path to the mp3 file to play, but I only saved the File name to the Listbox.So basically, I'm wondering how to be able to still select files in the Listbox and press Play, when the Listbox's Items do not include the full path to the actual files.I know I could just add the full path to the listbox from the beginning, but I don't think that looks good.So maybe someone can point me in the right direction, or maybe provide me some source code.

I am designing a degree audit program for school, and have a listbox where all the classes needed are contained. I have a separate form for each year (Freshman, sophomore, etc.), which also contain listboxes which are empty. The idea is to add the selected class from the first listbox into the empty listbox in the appropriate year form. However, to do this I would like to have the same listbox (the first one with all the classes) appear on each form, but still reflect changes made to it from other listboxes (classes transferred out of it).
To do this, would I need to create a listbox with global properties? Or would it be better to create a global function containing all the classes and have its contents called to the appropriate listbox?

Working with a couple of listboxes to display userid and emailaddress. I am writing an application for viewing SSRS reports instead of using the Report Manager. I am able to select the report and also send an email to users with a web link to SSRS report so that ReportViewer comes up for them to view, export or print the report. Currently I am only able to send to one recipient and I'd like to be able to send to multiple recipients. However I am having difficulty with the multi-select from a listbox. I have set the SelectionMethod to MultiExtended and so I can select multiple items from the listbox. Here is my code -

and I also add a messagebox.show to display my values, in EmailAddressTo variable, it displays "System.Data.DataRowView" so it was not able to capture the email address at all. Then if I debug further I eventually get the error msg - "The specified string is not in the form required for an e-mail address." because of the empty variable. Using SelectedValue, I was able to get at least the first email address but not the second one.
