I 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 believe the following code, which clears/unchecks the checkbox in the "RowSelect" column, actually runs, but it runs VERY slowly. In testing I have approximately 2300 rows in my DataGridView:
Private Sub btnClearAll_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClearAll.Click
Dim curRowIndex As Integer = 0
Try
dgvWISDataGrid.SuspendLayout()
For curRowIndex = 0 To dgvWISDataGrid.RowCount - 1
[Code] .....
The app appears to "hang" because this loop is taking so much time. When I hit the pause button, it always seems to freeze on the "dgvCell.Value = False" statement and when I hover over it the popup says "Property evaluation failed." Something is taking quite a long time or is interfering with this routine.

I'm trying to count the number of checked checkboxes in column 5 of the table. I've tried several approaches, but none have worked so far.This is the code I've written so far. As you can see, I've managed to count the number of rows.
VB
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
dbProvider = "PROVIDER=Microsoft.Jet.OLEDB.4.0;"
dbSource = "Data Source = C:/Databases/database.mdb"
con.ConnectionString = dbProvider & dbSource

I need a way to have 3 colums of checkboxes inside a checkedlistbox. I know i could do it with a panel, labels and checkboxes. But having them all in the control would be more convenient. I'm pretty sure there is no direct way of doing this, so i assume i need to create a user control. If you're not completely sure what i'm trying to create, i'm going for something that looks like this: [URL]

I have to implement a column (TransactionCompleted) which will only hold two states Yes/No. I am using SQL Express and wonder which would be the best DataType to go for that column, if I prefer to display the data in a DataGridView column as CheckBoxes later in my application?

I'm trying to loop through a column of checkboxes to see how many checked values there are in that column. The user has to have 2; no more, no less than 2, otherwise an error should show up.
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Dim count As Integer = 0
Dim x As Integer = 0
For x = 1 To DataGridView1.RowCount - 1

The error message still occurs when I have only 2 chosen in that column. I even tried this
If CBool(DataGridView1.Rows(x).Cells(7).Value = Checkstate.checked) Then

I have a dgv with a column type = DataGridViewAutoFilterCheckBoxColumn. I want to know if there's a way to I can get that entire column to become disabled (or Enabled = False) so it won't let the user click on the checkboxes. I tried looking in the "Bound Column Properties" but there isn't an option to disable the entire column.

I have an asp.net page which a user types in a "search" box, the code behind functions/subs etc produce a list of users matching the search criteria. In front of all the users returned in the search results, I have codded a html checkbox. Under the list of results, there is an "email users" button...
so.. I want to be able to click a number of checkboxes beside the results and then click on "email users" button which should take me to another page with email functionality so an email can be sent to all the previously selected users My confusion is over getting the "selected" user list from the results into the email page.
Because the checkboxes are manually coded within the code-behind file (ie the code basically generates a bit of html and pushes it into a label "placeholder", so I dont get any control functionality to get the checkboxes using the vb code, or can I?

I have a form which contains a checkbox field. On page load I want to create a separate checkbox for each customer in my Database. The code I have to create the checkboxes for each customer works fine. However, I also want to check in the database if the customer is set to unauthorized if they are then I want to check there box. I also have code for the case where the user checks a box. If a box is checked I update the database setting the unauthorized attribute to true. My problem is when I check a box it works fine and the box is checked, however if I reload the page all the boxes are unchecked. So either my database update is not updating the database or the way I check on page load for checked boxes is incorrect. Any ideas?
The code for the asp checkbox field:
<asp:CheckBoxList id="check1" AutoPostBack="True" TextAlign="Right" OnSelectedIndexChanged="Check" runat="server">
</asp:CheckBoxList>
The Code for the page load:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim sql As String = "SELECT Name, unauthorized, ID FROM Customer ORDER BY Name"
Dim dt As DataTable = db.execDataTableQuery(sql, "Customer")

I'm a newbie in VB.NET and ASP.NET. This is my problem:I retrieve a list of records from DB and, for every row, I need to show 4 checkboxes. I can use a checkboxlist for every rows, but it's not so clear how I can process the results after the submit.
I've some object and some operations available for that object. From database I extract a list of object with all operations. For every operation I want to show a check box to enable or disable the operation. The result is something like that:

Using VB
Say I have five checkboxes in a groupbox. I want to run an if then statement where if all boxes are not checked I would perform a certain action. I currently have it set to work using code similar to this
If box1.Checked = False And box2.Checked = False And box3.Checked = False And box4.Checked = False And box5.Checked = False Then
End If
Is it possible to reference the entire groupbox has having a false boolean property?
While doing this is managable - what if I had more check boxes?

I am working with an old web application developed in VB.NET 1.1 framework. I am having an issue with checkboxes. I have the following code for my checkbox:
<asp:TemplateColumn HeaderText="Reviewed">
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
<ItemTemplate>
<asp:checkbox ID="chkAppRev" Runat="server"
[Code]...
This all works fine until I add another check box in the asp code and another oncheckchanged method, it seems like it just skips over the query.

On a form I have a series of 20 checkboxes (cbS1 through cbS20). With that I have an integer named 'Count'
What I need to do: When the forms loads it will get a value for Count. I need all the checkboxes that are greater than this value to be checked.
So if count = 7 then cbS8 through cbS20 will be checked.
Im not really sure the best way to code this is. I know I can do it with a giant case statement...but there has got to be a better way right?

I have a datatable with a yes/no checkbox in it and when I filter my datasource it loads form2. Right now I'm using this code to have a label's color as green if it's checked and red if it isn't:
Private Sub Customers2BindingSource_CurrentChanged(sender As Object, e As System.EventArgs) Handles Customers2BindingSource.CurrentChanged
If ActiveCheckBox.Checked = True Then
Label1.Text = "Active"
[code].....
That works when I do something like bindingsource.movenext because it's in the bindingsource_currentchanged event, but when I try adding that to the form_load it's automatically set to Inactive, color red. I figured it's because is set to checked = false, but what event do I use to make this work when the form loads?
What's the value of a checked checkbox for the update/delete/insert commands? Like dates are DateDateTimePicker.Value.Date. Is it something like this?
.AddWithValue("@Active", ActiveCheckBox.Checked)
I don't use checkboxes to often.

VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.
