Delete Duplicate Records From Combobox?
Apr 28, 2010
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 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.

I'm trying to delete a number of records in a table from the last and forward. My idea is to use sql like this: delete top " & variable & " * from table where ID = something It gives me a general sytax error. Is it at all possible? Fuga. Edit: I also have the order by statement there. I just forgot to put it in the question.

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 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:

I am working with some DBF database files and have an interesting dilemma. I need to search through a table, find duplicates and delete them. Problem... Table doesnt contain a key.
So Table looks like this:
Name, BadgeNum
I need to be able to find instances like this:
John, 10
John, 10
and then delete just one iteration of John, 10.
Is this even possible? A "DELETE FROM TABLE WHERE BadgeNum=10" will delete both.....

I am trying to create a .Net application to edit a excel file by deleting some columns and keeping the columns which we need and then removing the duplicate values based on the first column which is going to be the Serial no. which should have a check to have 6 digits by default like 2563 should be displayed as 002563.
Code:
Public Function GetAllFileContents(ByVal path As String, ByRef errorMessage As String) As IList(Of String)
Dim contents = New List(Of String)
Try
Dim files = Directory.GetFiles(path, "*.xls")
If (files.Length = 0) Then errorMessage = "Please select the files"
For Each file In files
[Code] .....
I am trying to create something different by not only letting me do it for excel files but for say txt and csv files along with it. Removing all the values which I dont want and removing the duplicates and then if possible putting a check on the first column of data that the serial number number should have minimum of 6 characters and then The output file should have all the details in Uppercase

I have a Combobox in a Windows form that has a DateTime value as the Display Member and the Room Number as the Value member. When the user makes a selection in the combobox, a textbox is populated with the corresponding room number. There are some instances in the combobox where there are identical Display Member values. When a user selects one of the duplicate values and moves the mouse cursor away from the combobox, the combobox always defaults to the first of the duplicate items.
Example:
Here are the values that are currently populated in the combobox:
Display Member Value Member
02/25/2010 9:00AM 1
02/25/2010 9:00AM 2
If the second listing in the combobox is selected (the item with the value member of 2), and then the user clicks away from the combobox, the value default to Value Member 1.
Is there anyway to keep duplicate display members in a combobox while keeping the proper value member selected?
