Public MaintenanceMenuList As ListView Function AddItems()
Dim lstModules As New ListBox()
MaintenanceMenuList.Items.Add("item_1")
lstModules.Items.Add(MaintenanceMenuList)
End Function I am receiving an error like "Object reference not set to an instance of an object". What seems to be the problem here?
Maybe someone here can shed some light. I created a Windows Mobile application with a ListView control. I want to add items to this ListView.

I can add items to a listview this way:[code]But how can I set the Tag property of that same item as the same loop? I tried going ListViewItem.Items (0).Tag = "something"..But that doesn't seem to do the trick. How do I do this?

View 2 RepliesSo, i'd like to ask you! How can i add new listview items to a ListViewItemCollection (or something better), and than add the items in the collection to a ListView. The point of all this is to add listviewitems from a background worker.
View 2 RepliesThe following code will display items in the listview control when For Each strElementToSearch As String In fruitArray loops once using the string strTheses1 however when it loops again using the string strTR1 it will replace the items from the first loop.

What i was trying to do is put text in [COLUMNHEADER3] besides each of the names, so if "Graham's" details exist then put "PASSED" beside the name "Graham" and "FAILED" if it's failed, i'm not sure how to access the 3rd columns details to put that in is it:

View 10 RepliesI've got this code which basically loops through a set of folders and subfolders and finds specific file types. And then lists these in a listview. Now, it's intended to list exe and msi files. And I've made it so that these icons can be doubleclicked after they have been listed. I do this by adding the path to the file in it's tag property.
But, my superiors want a checkbox next to each item. So that they can check each item they want installed. And then have a button which runs the path in each tag property one at a time. It's basically the part where I fill the listview with the checkbox, filename of the exe or msi file, tag and the icon that I'm wondering about.
This is the existing code. This includes just a Tile view of the listview. Public Sub getDirectories(ByVal strFilepath As String, ByVal strFileExtension As String, ByVal objControl As Object)
'Load first files from the root folder. Then loop each subfolder
Dim di As New DirectoryInfo(strFilepath)
Dim aryFi As IO.FileInfo() = di.GetFiles(strFileExtension, SearchOption.AllDirectories)
[Code]...
But there should be a way of combining these two right? I'm not sure how I can add a checkbox in the first column of the listview? I've already set the Checkbox property of the listview to True. But I could use some pointers here if anyone's got any. :)
For some reason, the following code is causing me some issues. This code pulls lockout status data from AD and contains the data within a datatable. An event is raised from the threaded procedure to add the data to a listview control. For some reason one row of data gets added to the listview control and when you run the procedure gain, 2 rows of the same data gets added, and then 3 rows, etc.
This code calls the procedure "CallGetUserLockout"
GetLockoutStatusToolStripMenuItem.DropDownItems.Add("For Current User - " & User, Nothing, AddressOf CallGetUserLockout)

I am currently working on some tools and I am having some troubles adding new lines in a listbox.
vb.net
For i = 0 To lstFiles.Items.Count - 1
Process.Start("C:UT2004Systemucc.exe", "compress " & lstFiles.Items.Item(i))
If IO.File.Exists(lstFiles.Items.Item(i) & ".uz2") Then
[Code].....
The meaning of this code is that if the file exists, it will add a new line called Success below the dragged fileline. If the file doesn't exist it will create a new line called Fail below the dragged fileline.

View 7 RepliesI am very new to Visual Basic, and I need to add items from my database to the ListView control. I have a table in the database called tblChannels that I would like to draw the information from and populate the ListView control in VB, in the form of a column. I currently am unsure about how to go about doing this. Previously I have created combo boxes that draw the information from the database, but trying this method for the ListView does not work how I want it to.

This is to load them on startup:
For Each item As String In My.Settings.logs
log.Items.Add(item.ToString)
