View 4 RepliesI'm using Web Developer 2010, ASP.NET with the VB.NET programming language and a MS-Access database (.mdb).What I want to do is get all the data from a table called User (i.e. all the columns) where Username = ____, and then put the values in from the fields into text boxes so they can be edited. This is to make a 'My Account' page so that a user viewing the website can change his address, password etc.
I'm stuck at getting the data from the fields for each specific username.What I've done so far is this, but doesn't work:
Imports System.Data.OleDb
Imports System.Data.SqlClient

I have a chat server / client system running, but I want users to authenticate with my vBulletin forum database.I don't want the client to do it, because it is possible to fake the 'successful login' and connect with a fake username. I want to send the username and password details to the server, and make the server check it with the local vBulletin MySQL database for the username and password.Is there a way to do this? To my knowledge vBulletin has a username and a password entries in the database which is salted, and the salt varies from user to user.

I'm creating a rewards system for school where pupil earn points for good behavior which they can then use to purchase things like a packet of pens. (They can also have points deducted for bad behavior). I've created all the forms and now its just getting the data in from the Access database. This is what I need to do. On my form called detailsPupil it shows various information such as Name, email address, last login etc. This form is loaded once the pupil has logged in.
Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click
Dim Login = Me.StudentTableAdapter1.UsernamePasswordString(txtUsername.Text, txtPassword.Text, cboPermissions.Text)
If Login Is Nothing Then
MsgBox("Incorrect Username or Password")
[Code] .....
That all works but I'm having problems working out how to get the information like Name and email address into their places. This is what I have so far on my detailsPupil form.
Public Class detailsPupil
Private Sub btnLogOut_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogOut.Click
Login.Show()
[Code] .....
So to sum up I need to run a query which searches the DB using the Username which is obtained from the login form and then displays the Student Name in txtName, Email address in txtEmail etc...
Details: I want to compare these above two table1 and 2 . The unmatched records should be save in a new table .
objectives
1 Should take input the table and fields we want to match each other.
2 Then after searching or reading the record from table and selected fields save the unmatch records in a new table
I'm using VS 2010, and I did a project using VB and a database in Access. The problem is that when I try to put that "application" on other computers, sometimes, is not working. I thought it can be because on these computers they don't have access, but on one computer, is running another app which is using Access and there is no Access installed. How can I check if my application requires Access to be installed or not?
Here is a example of how I did the connection:
Public AccessOLEDBConnString= "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & myfullpath & ";Jet OLEDB:Database Password=password"
Function getConnection() As OleDb.OleDbConnection
[CODE]...
And when I want to have access at the data I'm doing like this:
dim conn as Oledb.OledbConnection
dim sql as string
dim ds as Dataset
