Searching Data In An Access Database?

Apr 28, 2011

I know how to search for one specific number from a single line in an access database using a query, but now I have to search through a whole database and display each instance. Ex) I search the number "1" in column "1" of the database and it has "2" instances. So now I have to take the corresponding data in the rows next to it in order to display them in the label.

search: "1", both results are ID = "1"

dates amount
10/13/2009 $43.00
12/25/2009 $86.00

I know how to put the results for "1" line of a database into the .item field, but im confused on how to search multiple lines of a database and store multiple items. Heres what I have so far...

Retrieving A Bit Column From Sql Database?

Jul 26, 2011

I have encountered a problem where in my database I have a column that is a bit either 0 or 1 specifying if a user is an admin or is account suspended or not. And in my VB code I am trying to retrieve that bit. Example code:

Dim dtRequests As DataTable
dtRequests = New DataTable("Users")
dtRequests.Columns.Add("SESLoginID", System.Type.GetType("System.Int32"))

Retrieving A PIN Code From A Database?

Mar 11, 2009

I am coding a banking and ATM application, which is split into two parts. In one part the employees of the bank can open new accounts for customers, edit accounts, etc. It includes assigning a unique PIN code for the customer. This is all saving to a database. The customer then uses the ATM part of the application to withdraw money. They use a unique PIN code to access their account. The problem that I'm having is retrieving the PIN from the database. I want to write a simple If statement, to match the PIN entered with the corresponding PIN in the database, so that it will retrieve all the relevant customer's details, eg. bank balance. The PIN is successfully saving to the database through the following....

Private Sub btnCommit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCommit.Click
If inc <> -1 Then


So how do I retrieve the PIN from the database that matches with the PIN entered and hence, retrieves bank balance, etc?

Retrieving Values From Database Into .Net?

Nov 15, 2011

I'm trying to create a function that will check the database and compare it with the value of my label. (Basically a Version Checker) If it is the same, then nothing is displayed, if not, then I'll disable some buttons and change another text to display something. Here's the code I have so far...

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I'm positive that I'm just not putting the correct calling reference in this part:

If Mydata(0).Read = Label2.Text Then

Retrieving Records From Access Database Using WCF?

May 18, 2009

I have a problem when trying to retrieve records from my Access database through WCF. In my application the user enters a Customer ID and the function then searches the database and retrieves all records related to that customer. However, it isn't working as it should. The code behind the search button is as follows:

Private Sub SearchButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SearchButton.Click


this code isn't doing as it should. The DataGridView should display the records relating to a customer but nothing is being returned at all, I'm not even getting any error messages. I've been looking at it so long I must be missing something ,
