I am trying to make a record counter for a textbox i have on my form. Basically i have an Access database called Member and wish too count how many records there are in the database and insert the figure into the textbox called MemberID. I am doing this to stop duplication in my form. I am doing it on the MemberID which is a Primary Key and not an autonumber
vb.net
Public Class frmMember

How would I be able to make a textbox (counter). text = to something. Following an earlier example, I came up with the code below but it returns an error
CODE:
i would like to display the counter after retrieve the data from Database.
I wrote this code but fail to show the counter
If userTable.Rows.Count >= 1 Then Dim allRecord As Integer = userTable.Rows.Count
[Code]...
Suppose I want to show a counter in a textbox w/a slight delay (for loop) after the form is loaded. I tried code below and it just shows the last #10.
Public Class Form1
Private Sub Form1_Shown(sender As System.Object, e As System.EventArgs) Handles MyBase.Shown
[Code]......
I realize I could use a timer or sleep function but I'm trying to understand why this doesn't and/or shouldn't work.
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

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.

[code] the user can input a 'receipt id' into a textfile press the button search and it will input the details of that particular receiptid into 6 different textbox's;What I want to do is move away from this and instead show every saved receipt that's in the database in the textbox's.(I am using MySQL)I've heared that using loops may achieve what I aim to do but havn't found any code online that uses mysql.

1. I am trying to sum up a record in ListView1 called NumberInStock and have that value added to a text box called txtInventoryTotal. I have been playing with code to do this and have come with something that is placing a result in my text box. The problem is that it is the wrong answer.
On my first attempt, I went through and created a new function called InventoryTotals() that calculates the sum of the NumberInStock but couldn't get it to display in the text box.
2. In ListView2, I want to show a location and then have the NumberInStock show a subtotal for what is available per location. How do I go about doing this? Do I have to create a connection to the database every time I want to accomplish this? Right now, doing that causes errors in Vs 2005. If i have more than one connection trying to access my database, it tells me that it cannot establish a connection to the database.
I have added a screenshot of my application in hopes that it gives you an idea of what it is I am trying to do.

I want to know how can I get specific record to make report? For example I have student information there in my program. Its easy to create a report of all students. but if user wants to get & print specific record of a student what should I do? I have another question to ask. I have heard it that its possible to show each specific record there in each page by using NewPageAfter or NewPageBefore. I need to know is there any way that user will select ID number from combo box & when he will click on report button it will create report of that student what has been selected from the combo box?
