Avoiding ListView Duplicates
Jan 19, 2009Im 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?
View 6 RepliesVS 2008 Removing Listview Duplicates...Again?
Mar 24, 2011I have 3 list views: (steps)
1...One column listview_AllAddresses, read from several .txt files containing email addresses (creating a list with duplicate entries)
2...One column listview_RemoveFromList, containing email addresses populated by textbox add or drag and drop from listview_AllAddresses (working)
3...One column listview_DuplicatesRemoved, where final list is to be diplayed without duplications entries and (no code yet) items from listview_RemoveFromList removed as well
4...Write to a .txt file containing adjusted list of email addresses
Private Sub Button_ImportSource_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button_ImportSource.Click
Try
OpenFileDialog1.Reset()
OpenFileDialog1.Filter = "txt|*.txt"

VS 2010 - How To Remove Duplicates In ListView
Jun 7, 2011Ok, I found some code online on how to do this, but they only compare the Listview.item.text, and they don't care what is in the entire ListViewItem.

Check Internal And External Duplicates?
Aug 24, 2009Recently, I have a requirement to develop a vb.net application wherein the input excel sheet data which has an average of 5000 records should be checked for Internal duplicates (duplicates within the same sheet) and external duplicates (duplicates which exist outside this sheet). I have gone through lot of logics..some of which are ...
- Common and currently testing out..
- First insert the excel sheet data into DB..then query by following
select distinct id,mobilenumber from scrubmaster where calltablename=<calltablename given by the uploader>
Then loop for duplicates...
[code]....
The above logic works but it takes very long time..I have tried other logics from web but they "Query timeout"...

View 1 RepliesSaving Txt File Check For Duplicates?
May 23, 2010Ok, 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).

LINQ VB How To Check For Duplicates In A List Of Objects
Oct 11, 2011I have a list of objects, each with 2 relevant properties: "ID" and "Name". Lets call the list "lstOutcomes".I need to check the list for duplicates (meaning object1.ID = object2.ID, etc.) and set a flag (valid = false, or something) if there is at least one duplicate. Also, it would be nice to send a message to the user mentioning the "Name" of the object, when it fails.I am sure I will need to use the Group By operator to do this, but I am not used to doing that in LINQ, and the examples out there are just not helping me. This article seems to be close to what i need, but not quite and it's in C#.
Here is a starting stab at it...
Dim duplist = _

How To Check If Listview Item Was Changed
May 7, 2012I have a window which has 8 items in a listview along with 2 radio buttons below the listview. The user is able to select one or more selections in the listview and turn the selection on or off with the radio buttons(live, prior to hitting the submit button), my question is how do I tell which selection was changed? I was going to put the one or more selections into a string/array and use that later for some messages once the user hits the submit button. I can almost think of it but can't quite get there, i'll be using an if/else with the .selected option in listview items but am not sure how to tell if the user, say,goes back and changes the option from On to Off(Off originally)to remove that option from the array.

ListView - How To Do Check On Date (Coming Up Birthdays)
Jan 9, 2010I am new to <acronym title="Visual Basic">vb</acronym>.net but i have been writing my first Application. The application is a customer database. I have a contacts form and in one of the fields the user puter their date of birth. Alk data is writen to a SQL database. I also have a listview on the right when the application lauches. I want this listview to show birthdays that are coming up in say the next 30days. This is so the user can send a card/ present.
Here is my SQL Update
"update Contacts set contactname='" & tbName.Text & "', PostalAddress='" & tbAddress.Text & "', PhoneNumber='" & tbPhone.Text & "',MobileNumber='" & tbMobile.Text & "', Email='" & tbEmail.Text & "',DateOfBirth='" & Format(dtpDOB.Value, "dd MMM yyyy") & "' where contactID ='" & localContactID & "'"
Then my listview has the select
"SELECT ContactName, DateOFBirth, ContactID FROM Contacts"
I did try
Dim todaysdate As DateTime
todaysdate = Date.Now.AddDays(+30).ToString("dd MMM yyyy")
But it is looking at the YYYY and for it to show evey year the YYYY has to be ignored.
