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.

I have an arraylist of a "Doctor" class containing Firstname, Lastname,etc. Some elements in this arraylist may be duplicates of others. I am trying to iterate through the arraylist and search for duplicates. Once i find a duplicate i want BOTH duplicates put into another array and removed from the original array.
here is my function
Public Function createArrayOfDuplicatesAndRemove(ByVal st As ArrayList)
Dim duplicates As New ArrayList()
Dim i, j As Integer
[code]....
How could something be out of range if i start at the end and work to the front?

I wanted to make a flow chart with more than 50 labels (see this link for just a small portion of the flow chart [URL]). I looked all around but couldn't find one in VB 2008 with the same problem. but anyway, my questions are:
1. Is there a way to set the color of all the labels instead of just one by one say:
Label1.BackColor = Color.FromKnownColor(KnownColor.Control)
Label2.BackColor = Color.FromKnownColor(KnownColor.Control)
Label3.BackColor = Color.FromKnownColor(KnownColor.Control)
...
...
...
There should be a way to loop through them
2. Is there a way for search through the Labels and find for example Label14? or a label with tagindex of 14? I rather be able to find label 14 but the tag also works.
3. Is there a better way to represent flow charts and stuffs like that in VB 2008?

i am trying to figure out how to go about finding this window's label when the control name is the same as all the other labels on the program.

All 3 labels are named the same. The one i am most interested in is a progress % counter (1%, 2%, 3%, etc..)How can i get the value (using a timer of course) from that label without knowing the caption of it at any given time?

I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?

Well im currently developing an application for public use, I have a login screen in which the user enter's their registered credential's and the progressbar loads by increments of 3, now i placed 6 labels ontop of eachother and where the progressbar coding is i put:
If Progressbar.Value >= 1 Then
Label3.Show()
If Progressbar.Value >= 20 Then
Label3.Hide()
Label4.show()
And so on up until Label8 Show at 100%,
Now the problem is... As i have placed the labels ontop of eachother i need them hidden until they are called to show, i have tried adding a background worker to do this but have had no luck, all i see is the labels overlapping eachother when i run my application when i want them hidden untill Label3.Show() is called, and then to display them as they are called and hide them when another one is called to show...

With VB, but I've got the few basics down, file naming, adding objects, naming objetcs, etc. But the reason I'm on here is because I cannot complete even the first step. Our form is 640 X 480, and we need to have two labels, both have vertical scrolls. I know how to add and resize the labels to meet my needs, but I do not know how to create scrolling labels. Or are they text boxes? On our bubble chart (Do you know what that means?) it says lblInformation. We are going to have clickable radio buttons which will update the lblInformation with info about each of the radio buttons.

I'm trying to make a program that allows the user to click on labels which have a number in it and then that value has to be stored into a different label.
For example the user click on label1 and the values goes into label12, then it click on label3 and the values goes to label13 and so on.
At the moment I can only code on the respective label underneath (1->12,2->13...) but it has to be in any order (5->12,7->13...)
Here a picture and below my code:

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?

i use csv file to populate my dgv. now i wanna eliminate duplicates from my dgv. i knew it could be done using unique datatable. but i wanna eliminate it from dgv not from the dataset or datatable.to understand it in better way- i wanna check column1 if the vales in column 1 are repeated then the entire row must be deleted i.e the duplicate row must be deleted( if column 1 has 2 duplicate values then 1 row must be deleted)

I'm reading and writing to an xml file and am looking for a way to identify and delete certain nodes. Below is an example depicting the data as rows with each row sequenced in "Sortorder". As you may note, "Sortorder=1" data is there twice.one row containing data... the other not. I'd like to keep the row containing data and delete the one that has blank data elements.

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. But for a big table this is very slow. 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?

I have to check duplicate records in ArrayList. In ArrayList each item should have atleast 2 times before insert new Item. Per example
Example 1:
AL(0) = '1'
AL(1) = '1'
AL(2) = '2'
[Code]....
Method has to return = 'false', because '2' has 1 time in the list. So I dont
want insert '3' in ArrayList and return false.

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?

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.

Dim arraylist1 As ArrayList
Dim arraylist2 As ArrayList

What can I do next to compare the two and write the duplicates to ListBox1.

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)() {}

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?

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

I'm trying to create a "LOTTO" number picker, but I don't want to have more than one TextBox. And I also don't want duplicates in that single textbox. The program randomly picks six numbers from 1 to 30 (Sorry I don't have the code at the moment).
My code runs fine, but I keep getting duplicates in the textbox. (I'll update as soon I have the code.)
