I have a Listview listing multiple files with the following code
Dim index As Int16 = 0
For Each Item As String In NewFilenames
ListView2.Items.Add(Item.Substring(Item.LastIndexOf("") + 1), index)
index = index + 1

I need to set all the checkboxes to true somewhere in this statement.
I did this once before but I can't find the code where I did it. I have 4 checkboxes and I want to assign them each a value like:
[Code]....
I've searched the net and even scanned 3 different computers that may contain that source code and have not had any luck finding it.
I have a TreeView with a parent node and two children node. Each of the nodes contain a checkbox stored in a TreeViewItem. I want the two children node checkboxes to be set to IsChecked=true when the user checks the parent node and I want the two children node checkboxes to be IsChecked=false when the user unchecks the parent node.

This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:

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:

Price - 5.89
Amount - 12

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.
How can you check all the checkboxes of all the items in a listview?
View 2 RepliesI am using VB express 2008 with MSAccess as Database. I have a table DailyExpenses in MsAccess with four columns of which one is ColumnPaid having checkboxes. I used following query to display records of DailyExpenses in Listview: Dim cmd As New OleDb.OleDbCommand("Select * FROM DailyExpenses ", con)
It is working fine but it displays False in the column PAID in Listview instead of checkboxes. How i can display checkboxes in Listview?
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.
View 11 RepliesI am working on my listview as I want to count how many checkboxes that I have ticked and unticked on my listview. Please can you tell me how I could do this?
If you do know how I could do this in simple way, I would be very grateful if you could tell me how I could do this.
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
View 15 RepliesI 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?
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 am using VS 2008.

View 2 RepliesI 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.
I have a VB.Net Winform showing checkboxes inside the ListView which works fine. I want to know how to make the checkbox work like the RadioButton. ie. I should allow the user to click only one checkbox on the listview. If there are 2 checkboxes in 2 rows and then when the 2nd checkbox is checked, the first checkbox "Checked" should be cleared. When the 2nd checkbox is clicked the 1st checkbox "check" to be cleared.

I want to save the settings of the checkbox when I tick and untick them in the listview, e.g tick and untick the checkboxes and save the subitems text in the label text.So I can read the settings from the label and split it to read each text.Do you know how i can save the checkbox settings before I can read the subitems text when I click on the button?

[code]...
so i have to use an integer when i dim it like:dim b as MyBool = 1 then when you look at it in the watch window b = {Yes} so i could settle for that, but with a boolean you can do this:dim b as Boolean without setting it to anything it defaults to False mine however, is Nothing. 2 things: 1. How can i get mine to default to No 2. How can i make it work like this: dim b as MyBool = Yes instead of having to use the integer this is not a requirement for anything I just wanted to know how to do it
This is probably a basic question, but I have never used this syntax before. Can someone tell me in detail how this expression evaluates to true? [Assuming IsOdd is a boolean type].
Dim i As Integer = 3
IsOdd = (i And 1) = 1
The expression 3>6 AndAlso 7>4 evaluates to
A. True B. False
The expression 4>6 OrElse 10<2*6 evaluates to
A. True B. False
The expression 7>=3+4 OrElse 6<4 AndAlso 2<5 evaluates to
A. True B. False
