Adding Items To A Listview As Well As Checkboxes And Tag Property
Jun 14, 2011
I'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. :)

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?

My program takes a checkboxed item and depending on the serial number that is present on the item on the invoice, subtracts one from the amount list I have the following in a listview on a details page which I added with the following code:
Item - Low Socks(pink)
Serial # - 34-75-860
Price - 5.89
Amount - 12
[Code]...
Right now it doesn't look like it does anything. I have tried changing my index's on my subitems to 1 and 3 instead of 0 and 2 but i figured because they are subitems that they need to be subitem index 0 and subitem index 2 since there is one item and three subitems to that one item.

I've got a listview with a bunch of items which all use checkboxes. Each time an item is checked or unchecked I want to save the selection. Whilst saving/loading the selection is not an issue, I can't seem to find an event which triggers AFTER the checked item has been changed. For example, the ItemChecked event will fire when an item has been checked or unchecked but the event will give it's checked status BEFORE it was changed. I've had to resort to saving the list when it loses focus but this isn't ideal.

I have a ListView with the columns 'Name', 'Expected', 'Total', and I want to add another column saying 'Recount' at the end. The 'Recount' column will ideally have a checkbox only if the 'Expected' value is larger than the 'Total' value.
So far I have got the ListView with columns and can add a check box on the left hand side, but that check box is not under a column heading (though I can probably put another column with no values in there to work around that) and it is on all of the records.

The 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. In another words I want to keep adding items to the ListView control. [Code]

I have a listvew that is setup like:
[COLUMNHEADER1] [COLUMNHEADER2] [COLUMNHEADER3]
[CHECKBOX] Graham
[CHECKBOX] Greg
[CHECKBOX] David
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:
formname.listview1.subitems("")

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)
[code].....

I 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.

I've created a treeview that is going to represent a 'table of contents' for a Word template I use frequently and I need to add checkboxes to each node of the tree view.
Here is some of my code so far:
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(2), tvwNext, , "3. Statment of the Issue and Solution"
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(3), tvwChild, , "3.1 Issue Details"
tvwSIGtemplate.Nodes.Add tvwSIGtemplate.Nodes.Item(4), tvwNext, , "3.2 Solution Details"
What to add to these lines to simply display a checkbox next each line?

This may sound like a silly question, but I can't seem to find an answer.Is there any way to "Check" a ListViewItem when the user selects it via property? I'm sure I can figure out how to do it in code, but I thought there was a property of the ListView. I looked through the documentation, Google, and in the properties panel, but I can't seem to figure it out

I have a problem setting the checked state of checkboxes in a listview programmatically.
Background: I have a Windows Form Application which uses CheckedListBox�s. The names/labels for each CheckBox in the list are imported for a database. Also in the database is a field which defines whether the CheckBox should be Checked or Unchecked. The program works fine.
Problem: My requirement is to add a tooltip to each item in the list of checkboxes. I have read that the best/easiest way to do this is to use a ListView instead of the CheckedListBox. I have setup a ListView with CheckBoxes = True and View = Details. I have populated the ListView with the items from my database. The ListView now looks exactly like the CheckedListBox and the tooltips work fine.
My problem is that I can�t seem to find a way of setting the CheckBox�s to Checked programmatically. Is there a way to do this, or is there a better way of achieving what I am trying to do?
