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.
Ok, my script which is a follow on from a previous thread on writing to a text file needs another thing added to make this one form hopefully complete. (in fact its two things).Firstly, when the 'Save' button is pressed, I want it to check to see if the textbox1 text is already used (textbox1 is the plu field, but still titled as textbox1). So if the save button is pressed, I want it to check first if that number has already been used, and if so, display an error message and don't save, and don't clear the fields so that way the user can enter a different number in for that item.
Secondly, several fields are numeric only. I've tried a couple of examples and are either too complex or just don't want to work for me. How do I ensure that some fields are numeric only (well one is a percentage, two fields are numeric and 1 is a currency field).
I'm trying to make a snippet that will remove duplicate lines from text files. However, I seem to be mixing my for loops up.. does anyone know a simple way that I could do this?
so here is my scenario. I have two input files... both are plain text files. File1 has customer name, customer address and invoice number. File2 has customer name, customer address, invoice number AND a keyline. File1 will only contain some of the records in File2, and it will change daily. I need to be able to compare File1 against File2 and output one file (preferably an Excel spreadsheet) with the info from File1 and the keyline from File2, that matches the duplicated info. I know the basics to get it to work, but I'm not sure what would be the easiest way of doing this... File2 can have up to 100,000 records per day. I'd only need to run it once a day though.
I have a database running on SQL server primary key is all set, my question is i dont want to allow duplicates in the primary key, i want everything to be uniqure. The database already has information in it, is there a away to set it so when i add a new row through the table adapter that it will recognise the last primary key value and increment it by +1?
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 have 2 files one is located at ("C:DNSREDIRlocked.txt") the other is ("C:DNSREDIRcustomb.txt"). What i'm trying to do is that i need to add the text found in customb.txt file to the last line in blocked.txt and remove any duplicates found in blocked.txt. [code]...
I need to go through a list of strings and count the number of duplicates and then print the string with the number of occurrences in one line to a file. Here is what I have but I need to only print the string once and its count.
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 want to track orders for my small furniture factory. I want to create a tracking number based on the OrderNumber+ProductID+SeriesNumber.It should look like this: 10085-88-01
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.
I have searched high and low for a solution yet still no luck, I have two arraylists populate with FileInfo and I want to compare the two and write the duplicate (matching files) to a listbox.Here is how I have populated the arraylists but in terms of the comparison I have not found anything that works:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim arraylist1 As ArrayList Dim arraylist2 As ArrayList
[code]....
What can I do next to compare the two and write the duplicates to ListBox1.
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 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:
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)() {} [Code] .....
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.)
What i want to do is to prevent duplicate entries of values in a column.I am using this code but it is not working.
