View 3 RepliesI 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 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]
View 4 RepliesI have a VB 2010 class like
Public Class cStar
Public Name As String
Public Magnitude As Single
End Class
I want to add stars into some doubly linked collection or list that is ordered by magnitude.
I tried to create my own list cList based on collection
Class cList Inherits collection error - collection not inheritable End class
I had hoped to enable things like
Dim Star1 as cStar
Dim Star2 as cStar
cList.AddFirst(Star1)
cList.AddLast(Star1)
Star2 = cList.Behead

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 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:

View 1 RepliesI'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 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)

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 have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?
View 18 RepliesSuppose I have a list of Cat.
Public Class Cat
Public Property id As Guid
Public Property name As String
Public Property race As catRace
End Class
How can I quickly transform this List(Of Cat) into a List(Of Guid) using the id property?
I could do :
Dim newList As List(Of Guid)
For each item in catList
newList.Add(item.id)
Next
But I think there must be a way to do this faster (1 LOC). I just can't find how.
I have an array of people stored in a custom structure array... how can i copy this array to a temp array so that the temp array has all the same values as the original custom array?
View 4 RepliesThis is probably a really basic question - but I have a list of items (custom objects) being passed from one winform (.net 3.5) to another. I want to create a local list to store changes that only get persisted if the user clicks save. Currently if the user clicks cancel - the changes are still applied in the first form because I assume the objects are reference type.I have the save working as it calls a service layer to do the save and then refreshes the other form - but not the cancel.

i have issue returning a list in a web method. here is the code

I am trying to get a count of all the times a byte sequences occurs in another byte sequences. It cannot however re-use a bytes if it already counted them. For example given the string let's assume the byte sequence was k.k it would then find only 3 occurrences rather than 5 because they would be broke down like: [k.k].[k.k].[k.k]. and not like [k.[k].[k].[k].[k].k] where they over lap and essentially just shift 2 to the right.
Ideally the idea is to get an idea how a compression dictionary or run time encoding might look. so the goal would be to get down to just 2 parts, as (k.k.k.) is the biggest and best symbol you can have.
