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:

I have a piece of code for a program where when a specific checkbox is checkedunchecked (In this case "Allyellow") it checksunchecks any checkboxes within a group of 14 with a lightyellow backcolor.
While the piece of code below does this fine it seems to me to be very clunky and it must be possible to streamline it.
Private Sub Allyellow_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Allyellow.CheckedChanged

Using .Net, I need to generate a response based on only the checkboxes on my form that have had there states changed. So how do I know if the check box has changed from its previous value before submission. I can't use the onchange event because the user may check multiple boxes before submitting.

I have several checkboxes in a groupbox on a vb 2008 express userform. I would like to check the checked status of each when clicking a command button and then write the checkboxes caption to be used in an email or print out. I've tried several methods and always end up with the same error "Invalid Cast Exception". I have read the help on msdn and still do not understand how to make it work. Here is the code I've been trying
Dim chk As CheckBox
Dim sb As New System.Text.StringBuilder
Dim names As String
For Each chk In gbInterior.Controls
[code]....
I have also tried the code below but cannot figure out how to check the status and print the checkbox caption.
Dim ctl As Control
For Each ctl In gbInterior.Controls
If TypeOf ctl Is CheckBox Then

Basically I just want to set up exceptions for my program to prevent errors. The problem I am having is that sometimes the field name does not exist. For example, I am setting focus to the username text field named simply "username". However, if the entry does not exist (name=username) then I get an error. So what I need is a simple if statement to determine if it exist beforehand.
If Webbrowser1.Document.All("username").Exist Then
WebBrowser1.Document.All("username").Focus()
else
Messagebox.show("Field was not found!")
End If

I'm using VS2010 and SQLServer 2008. I'm trying to test for DBNull in datafields, but every formulation of a test I have imagined (or found) throws an error. Specifically,"The value for column 'ColumnName' in table 'TableName' is DBNull." (system.data.strongTypingException).Well, not too helpful. I know it's DBNull, and I want VB to recognize this.Here is what I've tried so far (all with the same result).

I have a problem with the Validation of a Integer-Field in my application.Its an Access DB on a Windows Form.I implemented the validation in DataSet.vb using an ErrorProvider on my Form.The field name is FNr and should not accept duplicate numbers.If the field value is changed, a query checks if the number already exists in the Datatable and if so it sets the error on that field.If the user tries to change the field to a number which is a duplicate I want to cancel the input back to the original number. This works but the
Error message is still shown by the ErrorProvider.The code is partially in DataSet.vb and in Form.vb
Public Class Funktionen

I have an array set up to receive the names of forms when they open. The form name is sent as a Form not a String therefore when I run my code I cannot check for whether the field is empty in the normal way (ie. array(1) = "") as the "" are only usable with strings!
Dim Forms(24) As Form
Dim i As Integer
Dim Free As Integer = -1
[CODE]...
I only need a solution to do the same as array(1)="" but for windows forms.
