I badly wanna Serialize a Linked List into XML and deserialize it back when required. I didn't get proper results when i did google. But, I learnt through the following link that it's not possible to do so. [URL]
so i have a linked list of employee objects. I now need to iterate through the linked list to see if i can find a matching object. I could iterate though using the [code] What i'm not sure of is how i get the employees[x].EMID out to check it
I have a question about doubly linked list the uses student names and ages and creates them into node objects. the studentItem class is already created for me I just have to create the nodes that will hold each item entered. I am required to fill in the code needed for each function givien in the ICollections library that is setup for me. I dont know where to start out I'm trying to create a NodeLink class and from the class use the information to create the guts for the add function for my Nodelink Function I have the following:
Public Class NodeLink(Of T) Public node As T Public NextLink As NodeLink(Of T) Public PrevLink As NodeLink(Of T) Public Sub New(ByVal StudentItem As T) [Code] .....
I'm looking for a simple and efficient way to sort up to 60,000 strings that are 3000 chars long in reverse order and save them back out to a text file.
I originally thought of a doubly linked list, but then I realized that we aren't privileged enough to have pointers.
Is there some other way I can create an efficient linked list without pointers?
I'm supposed to create a linked list and add/remove items with a push/pop. Currently I can only push 2 items and pop one before it stops, and I'm not sure what I need to do to fix that.
I have been working on a number of card games. Important, of course, is shuffling the deck.I have come up with a few different ways to do this. Currently I do not shuffle, but to deal a card, I lay out the deck in order, selecting a random number between 1 and the number of cards remaining and selecting that card. I then remove that card from the deck so that another card can be picked.There are two main ways to do this, and I am trying to figure out which one is optimal.The first is to have an array of cards. When one card is dealt, a new array is formed with that card missing. I kind of like keeping the array size exactly the size of the deck, but perhaps this is not efficient. So, the first array has length n and the new array after the card is dealt has length n-1. VB.Net makes it simple to change array sizes around like this.
I am writing a small program to update data in a SharePoint list. Now where I cannot develop or use applications for SharePoint unless I am on a SharePoint server, I thought I would cheat the system by using Access to link to SharePoint lists, and then use Visual Basic to play with the Access tables. I need additional functionality other than what VBA can provide me, so that is why I am using the VB layer.Is it possible that this is not permitted? Whenever I try to update an item in the table, I receive the message:
"cannot update '(expression)'; field not updatable"
The word 'expression' here is not a filler I added, this is the actual error.If I try to make the edit manually in the table using Access, it works fine (I haven't tried it through Access VBA yet...).
How my code works is this:I have a Dataset added to the project which connects to the Access database. I add one of the tables to the dataset and create a Class object to reference the table adapter (essentially a Data Access Layer). I can read all of the data fine, and when a change is made in SharePoint, my application sees the updates when it refreshes. But when I try to write back to the table I get the error message above.
For Each r As DataRow In TableAdapter.GetData.Select("Name LIKE '*" & FileName & "*'")
[code]....
There are other columns in the table and some of them have default null values. I only want to update these two fields, but it almost seems like this is not possible. I thought I might be somehow opening the Dataset in a Read Only mode, but I can't seem to find that option anywhere.
This overload resolution failed error that occurs when I try to add the newly created integer array as an item in a generic linked list as per the following?
Imports System.Collections.Generic Public Class GraphData Dim mInput As Byte() Public Data() As Integer Dim SignalData As New LinkedList(Of Integer)(Data) Private Sub Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint [Code] .....
- VS 2008 - Sharepoint 3.0 - Access 2007 - Windows Vista (The machine I'm developing it from)
History: (Do excuse me if I don't reference different methods I've taken so far correctly, I'm still learning!) I am building some search software for a law firm that I work for in Australia. It's all coming along really well, but I seem to have hit a snag getting data out of sharepoint lists and into my project!
I first attempted to add a web reference to sharepoint and after a while was able to pull in all of the data from the lists, fantastic!(OR NOT!). The issue then was when I attempted to load it up into an array using XMLNodes, whilst it loaded up fine and I could see all the data, if there was a null value in one of the columns, it wouldn't pull that null value across, therefore, I couldn't really use the data...
I would like to create a little list in my Windows Form showing a list of custom colors with their 'friendly names'. Technically it can be anything (ListBox, ListView, Panel etc... whatever).
I simply want it to look something like this:
I would like to store data for this list in a simple TXT file in such form:
Quote:
Blue,Blue Red,Red #F6A118,My favourite color #004080,Another color
And of course I would like each element on such list to be clickable, so if I'd click 'My favourite color' it should return the color's HEX value (#F6A118).
I would like to create list of child objects from list of parent object. Like If i have list of bookingroom which has one member room then i would like to create list of room from it.
eg. code:
Dim BookingRoomList As List(Of BookingRoom) = New List(Of BookingRoom) Dim RoomList As List(Of Room) = New List(Of Room) BookingRoomList = BookingRooms.FillGrid()
[Code]....
Is there any short cut method instead of iterating over for earch?
I need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists. What I'm trying to do is this.Custom Object1 is Integer, String, Bitmap Custom Object2 is Integer, String, String
In one thread I'll be adding items to List1(Of Object1), and processing them, and adding the results to List2(Of Object2), however I need to be able from other threads to look at the list and say only give me the items where Integer = (my thread ID), is this possible? Any help, or even links to information that would be relevant to this request would be helpful?
Limited to using v2.0 of .Net framework (we use VB.net) due to environmental constraints on our servers.I've got an ASP.net webpage which pulls data from a webservice that performs checks on user accounts in active directory. Operators can check multiple accounts at one time using the web interface. The webservice returns a list(of AccountCheck) objects which themselves contain single properties like username, email address, and List(of AccountError) objects which contain multiple properties.[code]What I want to do is using some kind of repeater, create multiple panels or divs which contain labels showing the username, email etc, and a gridview which has the accounterror list bound to it to show all the errors. The users could be checking 2, 5, 7 accounts at once, and is dynamic.
I have an Object structured as follows:[code]I thought this would work but I keep getting the following error: Object reference not set to an instance of an object.
just needed to get my head round something. Say I have a class 'myClass' with properties ID and Name. Now say I have 2 lists of objects of this type as follows:
Dim list1 as List(of myClass) = GetList1() Dim list2 as List(of myClass) = GetList2()
What I want is to 'intersect' (this may not be the right word!) the two sets of data by the Name property, but bring back the ID property from list1. A suitable database analogy would be if list1 and list2 were tables, I'd want to do a left join from list1 to list2 on the Name field.
The scenario is this, I have several variables that are set as a list(of objects). The values for these lists are populated during code via a SQL query. I want to be able to take these values and then use them within another SQL query. Each time the program runs the values will be different and there will be more or less within the list.
I have a procedure in VB.net using VS.net 2008 which will get the list of Orders and build a XML file with the list of Orders as shown in the code below: As the number of Orders is getting huge, I want to build the XML file for every 500 Orders
[Code]....
Instead of building XML for all the records I want to create XML for each 500 records. I tried the following code and it is throwing an error saying Expression is of type Orders which is not a collection type.
I have started using BindingList(Of T) for my generic collections whenever I need the objects to interface with the GUI instead of List(Of T). This has worked well for me so far but a few of my collections are stored in Dictionary(Of TKey, TValue) and there doesn't appear to be a corresponding BindingDictionary(Of T).
Has anyone else come across the necessity to use this, and how did they achieve it? Should I implement this myself? (How?) or is there a better solution already available?
