I have 10 variables that have numbers at the end in sequential order (e.g. V1, V2, V3, ect.). I would like to perform a function to find what the position is in an array and then add then add the value to the correct variable. Can I combine V & and the number to manipulate the variable?

I have been working on a homework assignment and I am having problems with it. Okay here is my final code. I declare a variable that is not used yet. I am wondering if I need to use the index to somehow fix this issue with the consonants. Maybe I need to nest another if, then or do some kind of comparison to figure out if the word begins with a consonant then tell it to move the consonants to the end
'you know something like this below, but this is not my final code yet:
determine if origninalWord begins with a consonant
determine how many consonants there are before you reach the first vowel
If originalWord begins with 1 consonant
[CODE]...
But I do not know the proper way to code the begining in red color text the last two sections work for vowels and numbers. Here is my new code.
Code:

I have a number of tabpages that each contain a datagridview control only. Based on the results of a SQL statement I then loop through each tabpage and set its name. The reason for this is that at runtime (and depending on the results of the SQL statement), the contents of each tab page will change - henceI loop through the tabpages and set the name/ text (to reflect what will later be shown in the DataGridView)
The datagridview control on each tab has the default name e.g. DataGridView1, DataGridView2, DataGridView3 so it's easy for me to loop through them e.g.:
for i as integer = 1 to 3

I am making a simple console game. If you have ever heard of the board game code breaker you will understand better.
In my version of the game you will have to figure out a four number combination. The only numbers it can be is 1, 2, 3, or 4.
I need to generate four random numbers and put each on into its own variable. This allows me to call back each number.
How do I do this? I have been doing some research on random numbers and I use this code to generate four random numbers
Dim rnd As New Random()
Console.WriteLine("20 random integers from -100 to 100:")
For ctr As Integer = 1 To 20
Console.Write("{0,6}", rnd.Next(-100, 101))
If ctr Mod 5 = 0 Then Console.WriteLine()
Next
Console.WriteLine()
But I can't figure out to put each number into a variable so I can call the same numbers back.
If i have a variable '12'
and a variable 'hello'
how can i double the '12' each time the variable is used?
What im trying to do is have a textbox which the user writes in a number, the number they enter then determines the amount of times a variable is written in a textbox.
so if the user were to put '3' into the textbox and click go, it would print hello12hello12hello12, how can i increase the number 12?
what i want it to do is look like this when the user presses go: hello12hello24hello36

I have a button that searches through a binary file to bring up customer information with the following code:
[Code]...
My problem is, I need to create a variable which holds the record number, so that the record can be edited, and put back into the file at its previous location, how would I implement this? Not sure about the code.
I'm developing an app that should allow the client to add several content sections to a page (in tabs). However I haven't found a way to easily create a form for editing the tabs.Assume for now that a tab just contains a title. I have a form that adds a tab, that's simple. But I also want a form that displays a text input for each tab and allows the titles to be edited and saved. I'm struggling with two main concepts:How to dynamically display the fields after grabbing the tab data from the database (each tab has its own row in the table).How to loop through the submitted data and update each tab in the database.How to select a particular text field from the number (e.g. given "1", how to select the element with ID "TabTitle_ 1".[code]I thought something like TabTitle[0] would be acceptable and allow for easy looping (as it does in PHP) but it's "not a valid identifier" apparently.It's very possible I have the approach completely on its head.

I have a variable called VarNUM which stores a number from 1 to 10. What i want to do with this is based on the current number stored in that variable call a different set of variables from a module with Public Structure ITEM1. It has the same set of variables for ITEM1 - ITEM10 but with different values. So ya in raps how can i use the number in one variable to access a set of different variables? Something like ITEM(VarNUM) then the set of variables that all have same name but with different values so that i dont have to go,
Code:
if VarNUM = "1" then
name = ITEM1.name
store = ITEM1.store

Variable 'RandomNumber' is used before it has been assigned a value. A new reference exception could result at runtime.

I want to query items from countries that are selected from a treeview (with checkboxes). However the number of countries that is selected by the user is not known beforehand. So how can I make a proper query when the number of OR operators is unknown? For example: SELECT DISTINCT Item FROM Countries WHERE Country LIKE @c1 OR @c2 OR @c3 etc� and then add the parameter values based on the selected countries in the treeview. I looked into parameter arrays but can�t make sense out of it really

I have been searching the internet trying to understand in its simplist form why this behavior happens.
Dim mysingle As Single = 456.11 Dim mybool As Boolean = mysingle = 456.11
In the lines above mybool becomes false. I found this behavior when putting the single into a double I found extra digits showing. The .net documentations states a single is an approimate value I gatehr a single is a 32bit floating point number? But why are extra digits appearing when I have explicitly said what the number is.. surely the memory should store that numbers either side of my number are 0 to fill up the memory location?

I'm trying to alter the existing number formatting in my company's application to make it more readable for international users. This is a stock trading application, so most stock prices come in with numbers precise to 2 decimal points, like so-> 17.23 We could also get ticks in that have precision out to 4 decimal points, so a penny stock might be 0.0341. The original string format that we were using for stocks was "#,##0.00##" Which would give us the format we wanted (essentially trimming '0's). The problem here is the ',' and '.' are forced onto the user, where in many other countries the thousands separator is '.' and the decimal point is ','. Boss man doesn't want to use "N4" for all numbers, even though this would resolve the globalization issue. Is it possible to have a globalized custom string format?
Other options besides writing some middle man code to internationalize numbers formatted the original way or another string.format method?
