In my Windows Form I have a ComboBox that is filled by a Stored Procedure with a list of names. I have the Combobox set for AutoComplete to "Suggest" and From "ListItems". When a user starts to type in and the AutoComplete does not find any matches in the listitems the user can tab out of the ComboBox and leave what they typed in the combobox even though it is not one of the Valid Items. Is there a way to check the Comboxbox to make sure of of the selected Items has been selected?

As part of the application I'm writing in Visual Basic, I have written code to display records in text boxes and cycle through each of them one record at a time. I'm having trouble getting the code I've written to update records to work however. I am new to this however, so I'm sure I've made an obviously glaring error that you more experienced people can point out for me:
Public Class frmRecords
' VARIABLES TO AID NAVIGATION THROUGH RECORDS

I have ALWAYS used the SQLDataSource to update my records in my SQL Server 2005 database, so i am not really sure how this would be done in normal code. I am using VB.NET but if you are a C# developer and want to show me some code that is more than welcome as well.
I am using ASP.NET 3.5.My user will see a page with 5 Text boxes with their contact details in. Those details I will get from a SQL Server DB and when they go and change the text in the text box and click submit, it must then save the changes.
This is very easy with the SQLDataSource but how can i code this myself?

I know that when I add a record to a table through a binding source using a binding navigator - it completely handles the IDENTITY PK (it's bound to a textbox and you can see it immediately).
Now I'm trying to do this differently in another part of the program - here I only have a BINDING SOURCE - that's bound to a DATAGRIDVIEW.
I put a new record into the DGV like this
Private Sub vendorfilesDGV_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles vendorfilesDGV.DragDrop
If e.Data.GetDataPresent(DataFormats.FileDrop) Then

I'm writing a time entry program to record when an employee checks in and when they check out.I'm struggling on the part where I need to calculate a time span (time out / time in). I am selecting the In Time, Out Time, and Total columns.I want it to take the Out Time subtract it from the In Time and place that value in the Total column.I have so far and have tried several variations of different updates but have had no luck.[code]I keep getting a syntax error in the UPDATE statment.I'm not very fluent with OleDB yet and I'm not sure if I'm doing the update correctly.I have no problem with OleDB and single UPDATES or single field updates but when I am updating multiple rows with different values.

This is the form I'm having problems with. As you can see I've created a tab interface which is working. There are five text boxes on it which are binded to the Staff table in the database. When the tab is changed, the binding is changed to a new field. However, unfortunately, when a new record is selected, the data bindings do not update, and instead, the first record is always being used. We suspect the problem may be coming from the fact that there is code to unbind from the text box and rebind it again. This is the code I'm talking about...
Private Sub TabCheck()
If TabState = 1 Then
pnlTabs.BackgroundImage = My.Resources.tabs1
txtBox1.Visible = True
txtBox2.Visible = True

I have added a datarepeater to my project. I have added several items from datasource.
Some of the items need to be updated constantly. I tried to put my filler of the datarepeater to a timer, but it caused several problems.
Is it possible that I could put only the labels that need to be updated, to the timer. If so, how to give reference that which datarepeater row this lable belong to?

am using sql 2005 and vb 2008.i need to compare dates and select matching records betweem a selected date range.say records between 11/13/2010 and 11/20/2010.e.thing is working ok except when it comes to selecting dates between 11/1/2010 and 11/9/2010.this is happening because when am retrieving the dates from database,its being retrieved in the format 11/01/2010 instead of 11/1/2010 and so it reports no records found,and knowing the limits of sql 2005 this is the only way i can retrieve the date.
