Checking For Similar Duplicates?

Sep 4, 2009

I have a web site where users enter company names to use in the rest of the app. However, recently I've noticed that similar duplicates are appearing, e.g. someone will enter EastTec Solicitors another will enter EastTec Solicitors Ltd someone else will enter EastTec Solictors (missed the i out in Solicitors), when there should only be one entry of EastTec Solicitors. What is the best way of checking the database for entries similar to what they have entered? How would you about checking for spelling mistakes as well like the Solicitors one?

Error Checking On Datagrid

Aug 13, 2009

I need to validate that a user doesn't leave the name field blank when they add a record in a datagrid. See code below that I wrote to accomplish this. It works fine if the code is under the 'saveitem' event. However, I want to check it each time a row has been entered (the user may add several records before clicking on the save button). I tried putting it under the 'Row Leave' event but apparently that event "fires" when you click the add button and throws up the error message immediately. I thought about doing it on 'cell' leave but then could not figure out how to determine which cell column you are leaving in order to check the appripriate field.[code]...

How To Ensure No Duplicates

Feb 20, 2010

I have a problem with ensuring no duplicates. I have an Appointments form (frmAppointments) and within it exits 4 date time pickers. The first 2 date time pickers are dedicated to creating an appointment date whilst the other 2 are for the purpose of changing an existing appointment date. When the date and time is entered into either one of the pairs (of date time pickers), the values inside get transferred to 2 corresponding textboxes. The user then clicks Save (btnSave) and the values are saved to sql.

How can I ensure no duplicates (of the date and time) can be created?

Avoiding ListView Duplicates

Jan 19, 2009

Im adding listviewitems and want to avoid duplication. Now currently, I have resorted to looping through the listview and comparing each items text property against what Im adding.

The ListView has a .Contains Method but this does not seem to do what I would have assumed; for example [code]Is there a way of doing this so I dont have to loop through all the items?

Checks For Duplicates Before Insertion?

Jan 16, 2012

Im confused on how to write a code on checking duplicates before insertion on vb.net. I know the sequence on how to do it but its kinda confusing when writing a code.

1.) Create a query that will check if the mobile number already exists on the database

2.) If not, insert the new data

3.) Else, a message will prompt that "You are already registered".

writing this in PHP is kinda easy for me but in vb.net.. , unfortunately, not easy.. Im still a beginner on vb.net.

Finding Duplicates In Set Of Labels

Feb 25, 2010

I have a set of labels (16 to be exact) that I need to avoiding duplicates with. The 3 dropdowns get conceited to create the string at the end in the label. Two options I have are to wait until they click the "Generate Names" button to find all the duplicates, or to find the duplicate as soon as the 3rd dropdown box index changes (preferable).

All the labels have a similar name: cAname (where A = a number 1 through 16)
c1name, c2name, c3name etc.
I just need to loop through them, edit the border property of the labels that are the same.

How To Find Duplicates In String

Mar 25, 2012

I am trying to find duplicates in a string. The code works more than I would. The purpose is to create a jagged array with values and positions like this one:

myString = "1123464263948465475965069068547363532627281901"
jagged= {{{1},{0,1,42,45}},{{2},{2,7,36,38,40}},{{3},{3,9,31,33,35}},{{4},{4,6,11,13,16,29}},.........}

Value Positions
1 0,1,42,45
2 2,7,36,38,40
3 3,9,31,33,35
4 4,6,11,13,16,29 ......... and so on with unique keys and multiple or not values.

My code do this, but looping all over the string there a moment when it repeats values and positions, because already found them earlier. How do I make to keep just the UNIQUES? How do I skip the loop when the value is already in?

My code below
Public Class Form1
Public myString As String = " "
Public jagged()() As Integer
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
myString = "1123464263948465475965069068547363532627281901"
jagged = New Integer(myString.Length - 1)() {}

Loop Causes Duplicates In String

Aug 21, 2009

I have for-next loop that loops 6 times around before exiting. Each time it loops it adds a small number and a space to a string so I end up with a string containing 6 numbers separated by spaces. Whats ends up happening is I get "555 555 666 666 777 777" when I should get "444 555 666 777 888 999". I know for sure it isn't the code that generates or applies the numbers because when you put a messagebox.show at the end of the loop it works perfectly, so it seems to me something is happening to quickly but showing the message box every loop gives it time to catch up. What can I do here?

No Duplicates Allowed In Listbox?

Oct 8, 2011

i am currently having two problems with this assignment. The program allows the user to add new students to a listbox with a unique Id, lastname and test average. When adding a new student to the listbox, part of the assignment is to not have duplicate students added. I am currently stuck at trying to figure that out. I have figured out how not to have duplicate courses under the course information form but when trying similar code for adding a student i cant get anything i try to work. the next problem is when searching for a student from the list and clicking on the Course Information button, the course information added for that student needs to be displayed. My problem is getting the student searched information to show up right, but if i add three students and search for the first one i added and click on course information button it only shows the last student i added. this is my code for the whole program

Public Class Form1
Private allStudent As New List(Of Student)
Private currStudent As Student
