Connecting To Database Error
Feb 5, 2009
i am building my first VB.net application with a connection to an Access database. Now, this works fine when I debug, however when I deploy the application I get the error saying "Could not find file", which I assume means i have got one of the publishing settings wrong? I don't think it is a code error because it works when I debug, but if anyone wants to see part of it please let me know.

good mornign here again =D having a problem with connecting to a remote database via adhoc we are using a windows 7 ultimate 32bit OS platform =D
here is the connection message im encountering
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)
i have already enable the the Remote Connection enabling the both TCP/IP and name Pipes and its server authentication of our both msSQL server 2005 is SQL SERVER AND WINDOWS AUTHENTICATION MODE
and also i put a check in Allow Remote Connections to this Server...both our laptops...
but still encountering the problem... the default gateway of our adhoc is 192.168.137.1
sample code how i connect to the database
Imports System
Imports System.Data
Imports System.Data.SqlClient

I am connecting to Citrix database using SQL-defined ODBC. Having a problem with it. I am updating an existing application that uses the ODBC in SQL, and it connects fine. However, that database connection is secured, only available on the production side. The test side has a remote connection. I am attempting to change the remote connection values to match the parameters of the SQL-based ODBC, but the labels are different, and it doesn't seem to match. Specifically, I don't think I'm getting the DataSource correct. Also, it can't find the username and password that I use to log into the remoter connection - I get an error message "Invalid authorization specification".

2. I developed a form that had a combo box and Data grid view control The combo box is fed (linked) to a Access database list. The data grid view control is fed (linked) to multiple Access Databases. When I choose a name in the combo box, it loads a new database into the datagricview control. It works great. No errors. Note that all the databases are in my project file.Could not find file 'C:Program FilesMicrosoft Visual Studio 10.0Common7IDEBALSAMFIR.accdbI don't understand why it works in the form but not in the user control and why it thinks it needs to find the file in Common7/IDE/.

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?

Yesterday i was developing an application at home, i copied that application along with the db(sql server db) and brought it to office to continue it.
But when it tried connecting to the db, i got this error
Quote:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network interfaces, error 26 - Error Locating server/Instance Specified)
I am trying to learn sql server. The error is talking something about Remote Connections, but my db is local, it lies on the desktop.

I'm trying to write a method in VB.net so that when I click a button it queries the database and returns all the values which match a textbox which is located next to the button. I have no idea how to do this, I assume in the onclick method for the button I will need to pull in the value from the textbox, connect to the database and display the results to a gridview?

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]

I've installed a vb.net windows service on a Windows 2008 machine, that is attempting to connect to SQL 2005. The service starts succesfully, but can't see the database. The event log has the following entry. The description for Event ID 0 from source SU4.ESMR.DAL.Job.FillPriorityJobByType(oJobDS, TypeID: 3 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

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

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.
