Remove Duplicate Items But Leave At Least One Of The Duplicate Items In The List?
Mar 27, 2012
I have a List object and I want to remove the duplicated items but leaving at least one of the duplicated items in the list;I wrote something like this however I would optimize this code for better performance, is there something faster?
Const chars As String = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"
Dim rnd As New Random()
Dim mylist As List(Of String) = Enumerable.Range(1, 100).Select(Function(i)
when I load items in to a treeview, there's several items the same.Say it's like this:[code]How do I delete the duplicate items so it only shows subitem once?
I have a List(of String). For example: {"C1", "C12", "C10", "C1", "C6", "C22", "C1", "C6"}. I am trying to write a function to give me a list of duplicates: {"C1", "C6"} in the list. Each duplicate will be listed only once. The function I wrote does give me anything back at all. I can't figure out why. how to translate that syntax into VB.net since I am not up to speed on LINQ yet. It is here: How to get duplicate items from a list using LINQ?
''' <summary> ''' Given a List(Of String), returns a list of items that are duplicated in the list. ''' Each duplicate returned is unique.
My visual studio 2005 has been running great up till now The menu items in the menu toolbar display exactly as follows:File File Edit Edit View View File File Edit Edit View View Tools Tools Tools Tools Window Window Community Community Help Help Window Window Community Community Help Help
Error List is displayed as follows:(I've excluded the icons)0 Errors 0 Errors 0 Warnings 0 Warnings 0 Messages 0 Messages The standard toolbar images are also displayed in 'duplicate'
This is before I open a project and visual studio is on the start page. The 'duplicates' do not go away even when a project is open.When project is open, Solution explorer displays duplicate images as well
I've tried all the following but still cannot get it to display normally. Restored my computer to a time when it was working ok. Full scan on my computer with AVG premium which includes spyware etc (No viruses , etc found) All software is updated fully
I'm designing a web page with two dropdownlists, one for the Make of a car, the other for the Model, both bound to a database with separate SQLDataSources, and using a distinct statement. I add "All" at the top of both by setting appendDataBoundItems = true and adding items named all. Then when I fill the Make with a querystring all the model items get added twice (but only the databound items).
I am populating a combobox with data from a .txt file; however, there are 1000 entries but only 4 different possibilites 1, 2, 3, and 4. How can I have the combobox only allow a selection of the 1-4 with repeating all 1000 numbers?
I would.Error1The item "objDebugMerchGear.Form1.resources" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter.MerchGear...How do i fix it.
I have a VB.NET project with XHEO licensing(to license a product) and for that I am using <projetname>.PLSK file which was added to the my solution. When I tried create a new .plsk instead of existing one I got a error while building. The error is like this. "The item "objRelease<projectname>.plsk" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter. I am sure there is only one plsk file and when I tried to build with previous .plsk file got the same error. Where is that resource parameter are stored. How to delete that?
I was generously guided by the community to use LINQ to find duplicates on my listboxes the last time around. However, I am now in a tough spot because I need to find and remove duplicates from a multicolumn list view. I tried using LINQ but it says that the listview object is not "queryable". Is there a way for me to find and remove duplicates using only one column of the listview? [code]The code now runs fine when I call it. But it does not remove the duplicates:
Visual Basic 2008 rookie question. I am getting the error message 'Error 1 The item "objDebugCIT163Lab1Cdrb.WeatherReport.resources" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter.CIT163Lab1Cdrb'when I debug. I am familiar with Visual Studio 2008 having used it for my previous C# course. Zipped and attached the project below. I hadn't finished the coding, but this problem seems to be of a setup nature I should either resolve before I continue or start from scratch
How would one go about checking a listbox's items for duplicates? Basically I need to write a program that displays the teams from a text file provided by my instructor, in alphabetical order. I can do that, but what I can't figure out is how to prevent the For loop from adding a duplicate team. What I'm envisioning is:
If teams(i).name is not in lstTeams.Items Then lstTeams.Items.Add(teams(i).name) End If
I have a program that compiles and works so far, except for the above problem and my alphabetical order (which I can probably figure out on my own:
Public Class danbrockteams Structure team Dim name As String
[Code]....
This works except that my listbox is filled with the team every player is in rather than just listing all possible teams. Not exactly looking for someone to just give me the answer, as I understand things best when figuring them out on my own, so I suppose a hint is what I'm really after.
The problem is: I have a list of objects, with some containing the same PlanId property value. I want to only grab the first occurrence of those and ignore the next object with that PlanId. The root problem is a View in the database, but it's tied in everywhere and I don't know if changing it will break a ton of stuff nearing a deadline.
So, if I have a list of PlanObjects like such. Plan1.PlanId = 1 Plan2.PlanId = 1 Plan3.PlanId = 2 Plan4.PlanId = 3 Plan5.PlanId = 4 Plan6.PlanId = 4
I want to take a sub-list from that with LINQ (italics mean an item is not included) Plan1.PlanId = 1 Plan2.PlanId = 1 Plan3.PlanId = 2 Plan4.PlanId = 3 Plan5.PlanId = 4 Plan6.PlanId = 4
For my needs, it doesn't matter which one is taken first. The Id is used to update a datsbase record.
I got an error when I tried to open the designer for one of my forms in Visual Basic 2010 express and I had the option to ignore it so I clicked that (which I regret doing so much) and now my form is erased,but I still have the code for it.I tried right clicking and selecting show designer but it just brings up a blank form. I had a datagrid control called "DataGrid1" and when i tried adding a new control to the blank form it says that "DataGrid1" already exists but it doesn't.So after I resolved the first 85 errors I got one more that doesn't make sense:
Error 1 The item "objx86DebugWindowsApplication1.frmMain.resources" was specified more than once in the "Resources" parameter.Duplicate items are not supported by the "Resources" parameter.
i searched in Google,i ran with few suggestions, like deleting obj folder and rename the class names, those are not work for my project, still error is same like: The item "objDebugBillofLading.Resources.resources" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter. C:WindowsMicrosoft.NETFrameworkv4.0.30319Microsoft.VisualBasic.targets
Error1 The item "obj\x86\Debug\MassText.MassText.resources" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter.MassText.
I have one form in my project, and the project built and ran just fine until I added a method to it. There are no other errors. I tried deleting the files from the project folder it claims duplicates of, and when trying to rebuild, the files are just added back and the error is thrown again. Additionally, I have also tried deleting my *.resx files, and the project will not compile and run without them either.
I have a list of 100,000 urls in list(Of string) which can contain urls in the form. [URL] i have tried using a combination of regex and the Uri class, but that didn't help, so i dumped the code. How do i filter these duplicates and keep just one of these url
i am making a card game and you get three cards in your hand at a time, i am using a list and random assigning to set the cards in my hand as different numbers but they keep being all the same numbers, here is what i have, what should i add to make it be a different number for every one
Dim hand1 As Integer Dim hand2 As Integer Dim hand3 As Integer
I've come unstuck on a certain point. I am trying to find a way to compare two lists and output only lines which are unique. In other words, remove both occurrences of duplicate lines.I'm relatively inexperienced with VB.NET, but this is how far I have managed to come;
Code: Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim LinksList1, LinksList2 As String LinksList1 = Replace(RichTextBox1.Text, "#vch", "") : LinksList2 = Replace(RichTextBox2.Text, "#vch", "")
[code]....
1) search the array to find duplicates and add them to a second array, then have a second pass to remove anything which matches the second array.
2) search the array for one duplicate and store it, then search the array again to remove the duplicates, and run that process until there are no more duplicates.
Then again, I could be going about this completely the wrong way. If that's the case, feel free to knock some sense into me.
