View 1 RepliesI am writing a matching program, and need 24 objects to randomly appear, each twice, across 48 spaces. I figured the best way for me to do this would be to assign the positions a number 1 through 48. but the problem is I can't find a way to generate a random number sequence in visual basic 9 .netI found many examples in visual basic .net but the conversion doesn't work. If not some code, many some example programs that either use a random number sequence or randomly sets the position of objects.

anyone have some quick code on how to do this?
wmi is not a option.
I want to divide the content in my application to groups each group has its own rectangle border with the group name located at the top border, i've seen it before and i'm not sure what is the correct name of this control, anyone knows what I'm talking about ? EDIT: Ok, I found the Groupbox Control but how do i use it? should i just drag other controls inside it or i should add controls directly into it?

View 2 RepliesNew to programming completely,on VB 10 Express. I am in the process of creating a keypad which I can punch in numbers 1- 9 to enter a password. I have 9 buttons for the numbers. I've got the keys to print the numbers into the textbox above but when I press a second key it replaces the first number in the text box.
My question is, how do I make the numbers go in sequence, so instead of
(Press 1) - 1 -
(Press 2) - 2 - (clears 1)
I want it to go like
(Press 1) - 1 -
(Press 2) - 12 -
and so on...
I have this XML
<?xml version="1.0" encoding="utf-8"?>
<root>

And I also have this method, where I take two files and take some values from them, and then I merge all the values into an object in the second query:
Public Shared Function RetrieveTranslation(ByVal filefrom As String, ByVal fileto As String) As List(Of clsTranslation)
Dim valuefrom = (From l In XElement.Load(fileto).Elements("data") Select l.Element("value").Value).FirstOrDefault
[Code] .....
So, the problem is that when I run the code, there is an "Sequence contains no elements" error in the first query(valuefrom). I debugged and it says that there is nothing in the query, but I don't understand why? I'm curious to know if it is well done to do something like I did, create an object from two queries, putting the first value in the second query.
While going thru an msdn article, I found a reference to System.Query.Sequence class. But when I try to use it, I get error "Query is not a member of System"
vb.net
Public Sub Linq65()

Select New With {.Number = n, .OddEven = If(n Mod 2 = 1, "odd", "even")}
For Each n In numbers
[Code]...
The above code is vb.net version of this code from msdn. So what is the correct namespace of this class? Or I'm missing something else?

My first thought was to use a statement similar to this but apparently it is invalid:
For Each d...<rowset>.<row> In d...<rowset>
The reason that this code fails is that it never even enters the for loop, although I'm sure the if block code is wrong too which is why I put a comment there, but my main issue is making the loop work for reading each row in order.
I want to create an integer sequence in each page request.Here is my code:
Public Class Test
Inherits System.Web.UI.Page
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load[code]....
My requirements are just created the sequence using VB.NET code and of no database help. The sequence must be started at 1 and incremented by 1. My attempt to solve this is by using STATIC variable within the Page_Load which can retain the sequence value.But someone told me that my approach is risky because it's not thread safe. Is that true? Or how do I create a sequence for each request that is free from any problems be it thread safe or others?
UPDATE: I attempted to solve the problem another way. But I'm not sure the thread safety of my new solution. Here is my code, the call to Singleton.Instance.Sequence function will generate a new sequence value:
Public NotInheritable Class Singleton
Private Sub New()
End Sub[code]......
I need top create a function that gets the next integer in the sequence of 1 to 60. Each time the function is called, I need it to increment from what the last value was and return the next number as the result. It also cannot return the same integer in 2 consecutive calls. When the count gets to 60, the sequence needs to reset back to 1. I would like to function to have no parameters.
I have created a function that does this using the cache to store the last value that was returned, but I am worried that with concurrent calls to the function that it might not work as I expect and 2 calls could get the same integer.
Is cache blocking the correct method to use in this instance or is there something other method I am not thinking about?
Also, stuck using .Net 3.5 and this is a web application.
I just wrote this function based on using SyncLock. Any obvious problems with it that I don't see? I am using the Cache to save the last value that was returned.

I have built a blog platform in VB.NET where the audience are very young, and for some reason like to express their commitment by repeating sequences of characters in their comments.
Examples:
Hi!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

LOLOLOLOLOLOLOLOLOLOLOLOLLOLOLOLOLOLOLOLOLOLOLOLOL
..and so on.
I don't want to filter this out completely, however, I would like to shorten it down to a maximum of 5 repeating characters or sequences in a row.I have no problem writing a function to handle a single repeating character. But what is the most effective way to filter out a repeating sequence as well?This is what I used earlier for the single repeating characters
