I'm trying to connect a DataGridView to an access 2000 database on Visual Studio 2008. I keep getting the "Keyword not supported: provider" error, as I'm fairly new to windows development on .Net I don't know if I'm doing it right.Here's the code:
[Code]...
why i having this error and how can i encounter this error
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim connection As New SqlClient.SqlConnection
[code].....
My app fails at this line of code:
Dim objConnection As New SqlConnection(Application("ConnString"))
My connection string is: [Code]. I googled this problem and the solution for it was having a malformed connection string where the "provider" was being specified when it shouldn't have. Example conn string: [Code]. I'm not specifying the Provider so I think I have a different problem.
Tried seemingly everything here to get this to work but I keep getting "Keyword not supported" errors for just about every iteration of dsn-less connection strings I can find out there in internet land, two are shown below.
Public cnSystem As New SqlClient.SqlConnection
Public Sub ConnectToSQL()
Dim sConnectionString As String[code]......
what is the proper connection string for a DSN-less connection to a SQL server using the data objects I am using?
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

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..
I have a MySQL database I've created for my website, [URL]. I want to query the database, but I am unsure how to connect.
This is the code I'm using:
Code:
Dim sConnection As String = "Provider=MySQLProv;Data Source=my_database;User Id=my_user;Password=my_pass;"
Dim bSuccess As Boolean = True
[CODE]............
The MsgBox() returns a message that says: "Error: The 'MySQLProv' provider is not registered on this local machine". All I want to do is access the table in my database, is it possible? (also, without installing anything additionally?)
Does the .NET framework include ways to access MySQL databases easily?
Over the past few weeks I've been attempting to convert the readily available C# code for the Membership Provider etc whilst working with MS Access. I'm fairly experienced with VB unlike C# and have ran AccessMembershipProvider.cs, AccessConnectionHelper.cs and so on through 3 different converters. All of which have given a varying degree of errors, all of which I've fixed, either by ever so slightly re-writing the logic or in the Cryptographic case finding a working translation.
This evening I have fixed all of the errors from all of the now converted VB files (which I was pretty pleased about as you can imagine), I then created a simple login page to test this out, added a new user to the system and tried to login to find out I'm being told the username or password is wrong.Just to clarify, the converters all had an error or two or even more in some cases which I've bypassed but now I can't login - at all!!Finally I've written reams of code over the years and am really stumped on this one, has knowone actually successfully converted these files from C# to VB and actually got it working?? I'm not looking for someone to send me there hard work but I am almost at the point of not wanting to bother with it anymore and I just can't believe that it's not out there to download.
Iam having difficulty with what should be a simple program.I am trying to access a MS Access Database file (2003) using VS 2010 Visual Basic.It is a basic application of opening the Access database file and retriving informaion from one row of data. The Access file is called Billing.mdb containing the file in a table called Clients. My reference says to use the Provider as "Microsoft.Jet.OLEDB.4.0;
Debugging the program I get the following Error Message:
InvalidOperationException was unhandled
An error occurred creating the form.See Exception, InnerException for details. The error Is: Keyword not supported: 'provider'. The entire program is as follows:

i have 2 computers - a Server and a Client pc which is running on local area network with MICROSOFT SQL SERVER 2008 R2 Developer kit at the main pc and Client computer will need to connect to SQL SERVER at main pc using connection string.Let me named server computer as 'MAGNA-PC' and the client pc as 'LAC-PC' and database name is 'db_referafriend' so the code for MAGNA-PC(server) connection string is:[code] i GOOGLE and YOUTUBE for almost 2 weeks before i post . I know that i need to configure the sql configuration manager and enable tcp/ip also add a new port at firewall to allow remote connection also add the sqlserver.exe and sqlbrowser in firewall and I have also chosen "Using both TCP/IP and named pipes" under Remote Connections in the SQL Server 2005 Surface Area Configuration. and all of this doesnt work!

View 2 RepliesI've created a small DLL, an addin for Autodesk Inventor, this addin saves some information provided by the user and the program to an access(mdb)database.The whole idea behind this is that it allows users to quickly find drawings, assemblies and so on.The DLL works great on x86 systems however it has issues on x64 because I used ado.net.In a attempt to solve it I forced .net to compile it with the target x86 CPU settings.
However using this I'm unable register the dll (C:WINDOWSMicrosoft.NETFramework64v2.0.50727RegAsm.exe /codebase SavetoDatabase.dll )It says its not a proper .net dll file and therefore cannot be registered.
is there any other access-database connection provider (like dao or ado.net) that works on a 64 bit machine? Or do I need to change from mdb databases to another type (like mysql)? because sooner or later all machines its running on will be converted to x64.Or do I need to register the dll in another way?I've also tried to replace the conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0 with ACE, with no luck however
I recently upgraded my system to Windows 7 64bit and ever since then I have had nothing but issues with my code attempting to access an Oracle database. I was using msdaora for my connection string however that does not work in 64bit. I changed over to OraOLEDB.Oracle which everything I can find on Google says to use however it fails every time. I have installed Oracle 11g 2 times now and even tried reinstalling VB.net 2010 and still no luck.
Here is my connection string....
Code:
MyConn.ConnectionString = "Provider=OraOLEDB.Oracle;Server=emsp.grhq.XXXX.com;Data Source=emsp;User Id=XXXX;password=XXXX"
And I am inporting....
Code:
Imports System.Data.OracleClient
Yet when I try it says...

View 3 RepliesI 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.
View 4 Repliesjust 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?

So I downloaded the VB 2008 Express edition. My information is stored in a Access 2000 Database I'll call db1.mdb..After I connect I can't seem to run queries, it says that I don't have read permissions. I think this is because my string doesn't contain my workgroup information. I'll just explain my steps.In the Database Explorer I added a Database connection. I chose Microsoft Access Database File, with the Data Provider being
".Net Framework Data Provider for OLE DB"..I browse to my db1.mdb file. The file itself has no password to it. So I test connection and it is fine. Unfortunately when I try to run a query from the Database Explorer, it says I don't have read permissions.When I normally log into Access I fill in workgroup login info. My connection string doesn't have this information so I'm wondering if that could be the cause.[code]How would I add the workgroup login/password to the conenction string ad is this the possible cause?
I want to connect to a Access Database I've tried to do it though Data Binding and that doesn't seem to be working so I'm going to have to do this through Code... every book I have tells you how to do it with SQL Server but can't find a example for Access that doesn't involve just using the databinding tool. Writing the queries isn't a issue it's just connecting to the database and then putting that data into a couple of text boxes. Lets say the database is called TestData and the table is ClientInfo and we want to put Date, First, Last into txtBox 1, 2 and 3 respectively when the form loads.

View 3 RepliesI'm trying to connect to a access 2007 database with VB 9 and am having some problems.
I went to Data and then selected add new datasource.
Then I clicked on database and selected Next.
I click on new connection, change the datasource to access database file and then click ok.
It doesn't give me a browser box so I can choose where my access database file is. All it shows me is a connection string label and a text box to the right of it. I tried entering the full path to my accdb file in that connection string box and also just the name of the file itself since it's in the same directory but get the error message "format of the initialization string does not conform to specification starting at index 0."
Also, when I click on test connection, it always says succeeded even though no database has been selected.
