VS 2008 Richtextbox Ordered Lists ?
Sep 15, 2010
I have searched the Internet and this forum for any help on making specialized lists in a Richtextbox instead of the default bulleted list (i.e: Numbered, Upper Roman, Lower Roman, etc.). I know that the default Richtextbox only supports Bulleted lists. I have tried to find a custom Richtextbox control that does it and nothing.I found this code snippet on another site, but after messing with it for a while I just put this on the back-burner while I worked on other things.

When I select a row from my gridview by clicking on a linkbutton called 'Modify' and is the last cell in the row. Using the code below I can retrieve the key value from within the GridView1_RowCommand sub and move to the modify screen with the correct data.
Dim r As Integer = e.CommandArgument
GridView1.SelectedIndex = r
Dim Company As String = GridView1.SelectedDataKey(0).ToString
[Code].....
When I try to access the first row it returns the first row value from the original Gridview and not from the re-ordered one.

I have one list that pushes to another list. Think of a shopping cart situation. If you double-click on the white area after the list of items in the first window, I get a null exception error when I push the info to the second window. How can I avoid that error??
Existing Code is below...
Private Sub lstBooksAudio_doubleclick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstBooksAudio.DoubleClick
If lstBooksAudio.SelectedItem = "" Then
MsgBox("Please Click on an item.")

i have created a list of buttons using the following
Dim Butt(20) As Button
Dim i As Integer = 0
While (i <= 20)
Butt(i) = New Button
Me.Controls.Add(Butt(i))
i = i + 1
End While
this means that buttons are created in the code and not on the form to begin with, so I don't know how to create an event for the click of a button in a list. Is it possible to do it with a parameter for i so that there is only 1event for all buttons in the list, and i is the button index array clicked?

I have three tables,
Products(ProductID, ProductName)
Orders(OrderID, OrderDate)
OrderDetails(ProductID, OrderID) Junction table between Products and Orders.
For example, there are Three ProductID in Products table A01, A02, A03
Four OrderID in Orders table
1. 01/01/2009, 2. 03/01/2009, 3. 05/01/2009, 4. 07/01/2009.
OrderDetails data as below:
A01 -- 01/01/2009
A02 -- 01/01/2009
A01 -- 03/01/2009
[Code]....
then I want to display the date that A03 is not ordered from range 02/01/2009 till 08/01/2009 which could have the result like this.
DateMissingOrder for Product A03 in range of date 02/01/2009 to 08/01/2009:
03/01/2009
07/01/2009

Ever since I started using VB.Net I have been using the Generic List collection List(Of <Type>). Arrays, I haven't used so much. I used them a lot more when I wrote C code years ago.
1.) Are arrays considered a type of collection like Lists, Dictionary, Queue etc are? Or are they in their own category.
2.) Can I iterate over an array with a For Each loop like I can with other collections or do I stick with the normal For loop for arrays?
3.) There are certain methods that return arrays. Can I set a list object to hold this return value instead of an array?

I've written a program to work out the flight distance between a set of seven cities around the world using a 2D array but was wondering how I would if possible go about having the values for each city selected via two drop down lists (say start city and destination city).
Public Class frmDistance
Private Sub Flightdist_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim rowcolumn(7, 7) As Integer
Dim sr As IO.StreamReader = IO.File.OpenText("Distance1.Txt")

I'm trying to generate a report that shows the products ordered for a given customer.
I'm getting an error on the line that states:
lblList.Text &= rowInvoices(
"ProductCode")
& " "
& rowInvoices("Quantity")
The error message states: Column 'ProductCode' does not belong to table Customers.
I have three tables: The Customer Table, which points to the Invoice Invoice table via the CustomerID.
Also, the Invoice table, which contains the product code, points to the Invoice table via the InvoiceID.
If possible I'd like to bring in the Products table to get the Product description.

I have written a multithreaded crawler and the process is simply creating threads and having them access a list of urls to crawl. They then access the urls and parse the html content. All this seems to work fine. Now when I need to write to tables in a database is when I experience issues. I have 2 declared arraylists that will contain the content each thread parse. The first arraylist is simply the rss feed links and the other arraylist contains the different posts. I then use a for each loop to iterate one while sequentially incrementing the other and writing to the database. My problem is that each time a new thread accesses one of the lists the content is changed and this affects the iteration. I tried using nested loops but it did not work before and this works fine using a single thread.
Here is my
SyncLock dlock
For Each rsslink As String In finallinks
postlink = finalposts.Item(i)
[CODE]...
Finallinks and finalposts are the two arraylists. I did not include the rest of the code which shows the threads working but this is the essential part where my error occurs which is basically here postlink = finalposts.Item(i) i = i + 1
ERROR: index was out of range. Must be non-negative and less than the size of the collection. Parameter name:index
I tried copying it to a new list but dosent work.

I've got a couple of drop down lists for languages. I bind them to a language list that comes from a query. Then the fields are also bound to the row in the DB they relate to. I have several panels with the language drop down - each "tied" to a different table in my DB. When I call up different records on the same panel the drop downs immediately "set to the position" of that rows language in the list. But when I call up another panel - tied to another database table - I see that language in the drop down.

If want to do a DataView.Find on a DataTable that is already 'ORDERED' by the Column I am seaching, so a DataView.SORT should not be necessary, but it throws an Exception if I don't give a .sort command before the .find command. Is there any way to avoid this apparant duplication ? and speed up the search time. Its a very large table - 1 million rows. I am using VB 2010

[Code] my issue is that now i need two cases, first i need a query that will return the date created and modified of the table and i also need to know if its possible to query a list of table names in the database ordered by date created but that have a certain thing in their names. for example the database contains the following tables: [Code] and what i need the query to return is the tables that contain "Data", settings and employees are for the other functions of the program. so the query should return the 4 data tables in order of date created. but i have no idea how to go about doing that in the query, does anyone know how this is done?
