I have 50 Texboxes.
I need to count the number of duplicate entries, and provide a summary (count) for each product code. This makes it easier when the order needs to be placed, and the user don't have to count each value manually.
I have tried looping through all 50 boxes to no avail. This seemed easy, but, clearly I am to thick to think of a solution.

I have a windows form application that connects to an access database. When the program is running it connects to the database and populates several textboxes that are bound to the dataset. I have been researching for 2 days and cannot find exactly what..I need, although a few threads have given me a better insight into my dataset. I would like to type text into a textbox that is bound to the primary key and when I tab out of the textbox (lostfocus event) have the program do a quick search of all records in the dataset of the primary key and if a duplicate exists, msgbox the user that that particular text is a duplicate and is not allowed, however if the text is not a duplicate, continue the tab keystroke allowing the cursor to move to the next textbox bound to the database.

I'm currently using a timer to check for the time of midnight.At midnight each day I have to add a bunch of records into a database.My windows form program will be POSSIBLY running on multiple computers at midnight, meaning I may get duplicate records, because each running program will detect midnight at the same time and add the records accordenly.

I currently have a sql database linked to vb.net and I'm populating the comboboxes using SELECT statements. However, I'm getting duplicate records in the comboboxes.I have my database setup as 1 project to many submittals and 1 submittal to many items.
I have 3 projects in my sample dataset and I'll recieve 3 duplicate submittals and 3 duplicate items.
If I have 6 projects in my sample dataset than I'll get 6 duplicate submittals and 6 duplicate items.
I've tried adding distinct to my SQL statement, but that didn't do anything. Is there any reason why its showing as many duplicates as I have projects?

I need to disable a button after its pressed so the user does not have the ability to click it again as this would replicate the process in some cases.After alot of searching I found some tips - alot of code I found I could not understand.This is what I have come up with:
On page load:
If Me.Page.IsPostBack Then
'lblDetails.Text = "disabled"
[code]....
I also read somewhere that I should use: System.Threading.Thread.Sleep(1000) to delay the process or something - not entirely sure why I would do this though.Although, the problem with my above code is that when the code behind page performs validation checks, it exits sub before executing my INSERT SQL code - so when it does this it also disables the button.I am not entirely sure if the above method is fool proof or whether it is a **** piece of code that won't work 100% of the time.On another website I found a script to put on the actual HTML page with <script> tags:
Code:
<script type="text/javascript">
disableSubmit(frm) {

I need to get the count of the records in my app. But BindingSource.Count always counts NewRow too if I select the new row. And this causes an exception. Is there any different method for it?

I am using a table adapter and the update code as below in a Try/Catch block as shown on the MSDN site.
Me.MyTableAdapter.Update(Me.MyDataSet.MyTable)
This all works fine but I should like to return to the user a MsgBox which displays the count of new records added and/or existing records amended.I know I could count the records in the underlying table before and after the update, the difference being the count of new records. How can I count amended existing records ?

I am trying to count the number of records that match Course_ID = 1 in a table.
Here is the expression I am using
=Count(IIF(Fields!Course_ID.Value="1",1,0))
also
=Count(IIF(Fields!Course_ID.Value=1,1,0))
I always get the number of records in the whole table and that is not what I want.

I have the following search code which works fine. However, I have an additional task to do, which is create a count function for the Record found or Record not found. Presently what it does is it searches and if a record is found it displays at the tooltip "Record Found" if not it says "Record Not found". However, sometimes you have 2 or more records. Therefore, the tooltip should say the exact amount of records found.. For example, 3 Records Found or even 5 Records Found. Also if only one record is found it says "Record Found" but if more it should display " 2 Records Found".

I have a query (qryTallyMedalInformation) that i bound on datagridview and it has 5 columns ( country, athlete, medal, game and date). Instead of having country in the datagrid, I want to use it in a combobox to display records base on country selected.what i did (with wizard) doesnt work fine though. My country combobox shows duplicate data and the datagrid is showing all the records from different country. In one word I JUST DID NOTHING.
