Dec 7, 2011I have a VB 2010 class like
Public Class cStar
Public Name As String

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

I had hoped to enable things like

Apr 5, 2012This is the xml I got as an output from the WriteXmlString() of Infragistics ultrawebtree. I am using this to create another Infragistics ultrawebtree with the same structure. But here I don't want the <Url>something.aspx..</Url>. I want that to be like this <Url><Url>. So how I can able to remove. This I get as a String. So I used Regex.Replace(). But it will work for certain conditions,but for some case it will destruct the xml by deleting some xml tags and xml became not valid due to missing of tags.

Sorting Thousands Of Records - Linked List?
May 6, 2009I'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?

Rebuild Array Versus Linked List Traversal?
Mar 11, 2010I 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.

Update Records In An Access Table Linked To A SharePoint List From VB?
Jan 23, 2012I 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.

VS 2008 Connecting To A Sharepoint List Linked Table In Access 2007
Apr 30, 2011First timer here, I love the site!
Running:
- 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...

VS 2010 Clickable List Of Custom Colours Linked To Text File?
Aug 21, 2011I 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).
TreeView - How To Remove Initial Root Node Indent
May 4, 2010I have a listview which I am trying to remove the initial root node's indent. My problem seems to be that I can't even set the indent value of the treeview in it's properties lower than 19, and if I try something like:
TreeView2.Indent = 16
16 seems to be the lowest value that makes any visual change.

Remove Items In One List From Another List?
May 2, 2012i am writing a program that reads a excel report from accounting software with our weeks orders on... so basically the program reads a list of around 100 items which all works fine.I also have a database that holds info on each item, when the excel sheet is parsed the software checks to see if any new items have been added to the list that are not on the softwares database. this is where i am having the issue.I have two lists: ItemsOrdered & ExistsingItems.
All the items ordered this week are in ItemsOrdered and all the items not in the items in the database are in the ExistsingItems list. using these two lists how can i find items that are in ItemsOrdered but not in ExistsingItems.
Change The Background Color Of A Node That Is Being Hovered Over While The User Is Dragging Items From A List Box?
Jul 26, 2009I'm trying to change the background color of a node that is being hovered over while the user is dragging items from a list box.I've gotten both functions to work separately, but while the user is dragging, the NodeMouseHover event does not fire. Is there a way to do both?

If Me.CanMove(e) Then
e.Effect = DragDropEffects.Copy
[Code]...
Note: CanMove() is a function I made that verifies the dragged data. Nothing else. And I will change "Color.Blue" to a system color later.
