Connecting A .mdb Database With Password?

Mar 8, 2012

I use VB.NET 2010 Express and Windows 7. Access is not installed.The code used to connect database password protected, is:

Public Class Form1
Dim cn As OleDb.OleDbConnection
Dim cmd As OleDb.OleDbCommand


The code is not working. I get this error: "Could not find installable ISAM".

NB: The error occurs only if the database is password protected!For unprotected database, code works without error.

My code is:

It works for a database without password. But for a database with password and the string: "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:DBB.mdb;Jet OLDB:Database Password=xxx"

I get an error:"Object reference not set to an instance of an object." Where wrong?

Connecting To A Access Database Via Account Name And Password?

May 9, 2009

I'm trying to use two different methods of connecting to a database to edit data, the declaration below is working:

Dim rsConn As ADODB.Connection
rsConn.Open("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" _
& Application.StartupPath & "VFMS_DB.mdb;" _
& "Jet OLEDB:System Database=Security.mdw", "Ads", "1234")

but now I want to do the same thing with the declaration below but I keep getting the message "Not a valid account name or password.

Dim conn As OleDbConnection
conn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" _
& Application.StartupPath & "VFMS_DB.mdb;" _
& "Jet OLEDB:System Database=Security.mdw;Database Account=Ads;Database Password=1234;")

I pretty sure it's because of this ;Database Account=Ads;Database Password=1234; not being correct. I tried ;User ID=Ads;Database Password=1234; and also to make it look like the first statement but neither worked.

When I try to open the DB from access it works fine, but when I try to run my Windows Form application from Visual Studio Connection String, I get a message that "Not a valid password".

Asp.net - Connecting To Remote Computer Using WinNT:// Provider And Directory Services Ignores Username/password

Jun 10, 2010

Here is the final code that worked for me. This uses WNetAddConnection2 to establish a connection first, before using DirectoryEntry.

Imports System.Runtime.InteropServices
Imports System.Net
Imports System.DirectoryServices
Imports System.IO

[Code]...

So I moved the code to an ASP.Net web app, which is impersonating a service account through the Impersonate section of web.config. The account I am impersonating does not have admin rights on any of the workstations so I put in a username/password into the constructor for the computer entry like so:

Dim deComputer As New DirectoryEntry("WinNT://" + Computername + ",computer", username, password).The username is that of a domain account which has local admin rights on every workstation. If I look at the Username property of the resulting deComputer object I can see that the username matches what I entered.Also if I enter in an invalid password it throws an error, so it is authenticating in some fashion.

However if I now try and add or remove a user from a remote workstation I get a general access denied error. If I add the service account that ASP.Net is using as a local admin on that workstation it will add and remove no problem.So next I tried using the LogonAPI (advapi32.dll ->LogonUser call) to login as the user account that is a local admin on all workstations, impersonated the resulting WindowsIdentitiy and tried running just the original deComputer instantiation. When I do this every property, excepty Path, returns an OLE exception..

Connecting To SQL Database

Feb 8, 2012

I am a wannabe programmer but quite new, started with VB.net about 1 month ago.I write on this forum because It's the first time that I'm actually stuck. The problem is I cannot find a way to connect to SQL server database I have created and saved earlier on my HD using visual express 2010. I want to find a way to connect using code, not by click and drop. I just hope you won't find my issue too trivial to even answer it.The project is very simple, it just consists of a button that should connect to the db on click.[code]

Connecting ComboBox To Database?

Apr 1, 2010

i'm fairly new to VB and am doing my second system through it. I am at the point where i want to link a combobox on my form to my access database so that when i click the dropdown arrow a list of surnames from the particular table in my access database appears.

[Code]...

First things first is this code remotely close to doing what i want it to do? I have to use an access database and i am familiar with this particular method of connecting to the database (sending any data to it is easy now). Secondly when the form opens (since the sub is called at load) i get the annoying old "object reference not set to an instance of an object" message.

Connecting To An Access Database

Oct 8, 2008

I have a VB.net program connecting to an Access database. I use ADODB as connection (force of habit, I suppose). The program runs fine on all my machines, but on some of the client machines I get an error on the connection to Access. It is intermittent (sometimes runs without any problems) and happens at different places in the code, but always at the connection with the database. The program connects and closes connections quite a few times during a calculation.

Connecting To An Access Database .mdb?

May 29, 2010

just a few questions. I have read through a of tutorials and snippets on access database.Connecting, updating, inserting, deleting, etc. My main question is this, I have not yet coded the connection to a database using code such as you all. I have always used the wizard to create my connection, table and view this also add the database to the project. Is it better to code the connection, or use the wizard? I have just started creating a program to feed company keep track of there inventory, right now I have 2 tables (feed, misc) both table contain the same things (code, description, price, and quantity). Any way I am getting off the subject, Write the code to connect to the database or use the wizard?
