I have a sub which requires multiple counter variables. Is there a more efficient way of doing this. My example is simple. Image if I had 20 separate counters I was trying to manage. I would have to create 20 separate variables and then increment each in the desired place in the code.
Dim Counter1 as Double
Dim Counter2 as Double
Dim Counter3 as Double

I'm trying to load a file where this file has, like, 10 lines. And I want to load each line (0 to 9) to each TextBox in my app (TextBox1 until TextBox10). So, there's a way to do this with a counter?
Like this mine code (that doesn't works):
If (System.IO.File.Exists("configs.ini")) Then
Dim configs As String() = System.IO.File.ReadAllText("configs.ini").Split(vbNewLine)
Const Max As Integer = 9
Dim TextBoxes(Max) As TextBox
For i = 0 To Max
TextBoxes(i + 1).Text = configs(i)
Next
End If

I have a for loop which goes like this -
for i = 0 as integer to 100
result &= "Name" & sqldr("name")
result &= "Lastname" & sqldr("lastname")
result &= "dob" & sqldr("dob")
next
The sqldr is the sql datareader (not important here)
I want my end result to be
Name1 = Sam
Lastname1 = Davis
dob1 = 01/01/1966
Name2 =
...
Name3 =
And so on depending on how manyrecords are in database. How do I make this happen in this for loop?

The program is to take an entered string then search for a subset of letters entered through and input box.In my subprocedure Sub btnSearch_Click I am using a loop to move through the entire length of an entered string to search for a set of letters entered through an input box. I can find the set of letters to search for but instead of increasing my counter "Found" for every instance of a match it returns the length of the string instead. I just don't know why the IF doesn't prevent the counter from increasing for every element in the string. I want the counter to increase only when the match is found. I just put 2 message boxes in there to make sure it found the right letter and then display the counter.
Here's the entire
' Name: Count Project
' Purpose: Displays the number of times a sequence of characters
' appears in a string.

I want to write an Excel macro to set print formats in all worksheets in a workbook. I don't think you can do this by grouping; it appears you have to do it in each individual worksheet. I want to be able to run a macro in any workbook to loop through all worksheets in the workbook and then select the first worksheet.
How do you have the macro determine how many worksheets there are and set the loop counter equal to that number?

We have a project that needs to gather survey data. On one particular page of the website, there are 21 questions each with a scale of 1-5 where the user selects one radio button for each question in the table. The survey is being coded in VB.NET. The data submits to an SQL database. All the radio buttons are similarly named, so only the number changes for the question [Code]

Im writing a program and its pulling data from a .MDB to put in a .DAT file.
Here is my while loop:
vb
database_connection()
sql = "SELECT * FROM tlalist"
[Code].....
In my database there are currently 6 rows. and only 1 row has the TLA_DAY column equal to 1, but for some reason when I look at the .DAT file it creates it outputs the result twice rather than only once.
Once JTLA_count increments it becomes "2", but the while loop still outputs as if its still equal to "1". Ive used breakpoints and the counter is incrementing fine.

I have this code sample from a book I'm reading which looks to be incorrect:
Imports System.Diagnostics
Sub Main
Dim pc As New PerformanceCounter("PerfApp", "Clicks", False) 'excepiton here
pc.Increment()
counterLabel.Content = pc.NextValue().ToString()
End Sub
There excepion message I get is: The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly. I looked for a property to see if I can set it but couldn't find one.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

Option Strict On

In the following block of code always returns zero for the CPU usage. However, if I run it through Visual Studio in debugging mode, do a "Quick watch" on the variable "pcCPUCounter", add ".NextValue()" at the top, and tell it to reevaluate, that returns the varying percentage (eg, 5%, 71%, 16%, etc etc) as the processor utilization fluctuates.
Why would the code always print out zero, but the quick watch doesn't?
Private Sub UpdateCPUUsage(ByVal strSelectedServer As String)
'Performance items come Performance Monitor: perfmon.msc.
'The right-click on columns at bottom and select "add counter" to see list.

How to make my counter work. I keep feeling like I'm putting it, or maybe just part of it, in the wrong place so I've been moving it all over the place but haven't found anything that works yet. I'll paste my code below and it will be the code that seems to not stop when it reaches the end of my counter. Other ways I've tried it make it stop after one or two, depending on what I did to the code at them time.
Here's what I have at the moment:
Public Class mainForm
Dim guessCounter As Integer
Dim correctAccumulator As Integer
Dim totalAccumulator As Integer
Dim answer As Integer

I am trying to create a list box that can have things added and removed from it with the use of add and delete buttons in subroutines, i have also got a limit of 20 as the maximum number of items in the list box, also i would like the list box to be able to update the number of items in it after the user adds or deletes items from it: here is my code:
Public Class Form1
Private Sub cmdAddZp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddZp.Click
[Code]....
the first part is for limiting the number the user can add to the list box, the second part is the delete function and the last part is trying to count the number of items in the list.
