i am relatively new to VB and i am working on a Visual Basic Program to build a Student Record Book where all the information is stored to an Access 2007 database. If the user is an administrator they will be able to add a new student, update delete etc. I managed to implement INSERT/DELETE/UPDATE functions and also a search button and they all appear to be working fine.

I have an application that has an Ms Access 2007 DataBase which runns great if access is installed. Is there any code that I can use in vb that I would be able to run access with out installing it.
View 5 RepliesI have an application that uses an *.accdb file as the back-end database. Connecting to and retrieving data from the access file is not an issue and is working quite well. However, as a precaution, I have the application first check to make sure the database file exists in the application's folder while it loads up. As a convenience, if the database file is not found, then the application creates a new (structured, yet empty) database. The creation of the actual *.accdb file and the creation of the tables is complete and is also working well.

My problem is that, whenever i add a new record and clicked the Save Record button, the msgbox "Data Update Failed" popped out. But when i recheck, the newly added record was actually successfully saved in the database.
Is there something wrong with my code? The new record is inserted in the database but why does the "Data Update Failed" msgbox was popped out instead of the "Data Saved" msgbox?? I've tried many times but i still cant figure this out. please help.

I am trying to run a query an Access db from VB. The general query which I want to run is
SELECT * FROM Patient WHERE Patient.PatientID = ?
or SELECT * FROM Patient WHERE Patient.PatientLname = ?
I tried using an input box which captured the user input and pass that variable to the query, but that failed. Then I read about writing a function and using that, however, I keep getting an error which says Function not defined, but when stepping through the code, it seems to work. Here is my function: [Code]

Basically, i've got a problem linking a data source (Access 2007 database) to a VB 2008 project.
I've broken it down to having a problem dragging a table onto my form, when it generates the nav bar, it says "0 of {0}", and the table is empty (despite the actual database containing values)
However, this happens only at home, at college it works totally fine. The only difference that's obvious is that i'm using Windows 7 at home, and Windows XP at college.

i seem to have a problem when i try to update a certain record in an Access 2007 Database. I have a small Access 2007 database with 1 table which has 3 Columns and several records. The 3 columns are RecordNumber (Primary Key and it is autonumber), FirstName(text) and LastName(text). What i am trying to do in VB 2008 is implement a search form which when you find a record you can update it. I do not have any problems with the search, but i cannot seem to edit any other record than the first one. For example i search for John which exists, if that record is the 3rd record when i try to edit it whatever changes i make (for example change that to James), the changes i make are made to the first record and not the current one. I tried a lot of things but nothing works, here is my code:

I am connecting to an Access database and using a parameter query with the LIKE operator to return all rows that match query. The string to search for is taken from a Textbox
sql =
"Select * FROM Allview WHERE Info Like" &

The query does not return any data in vb, but when run from access with same string, there is data returned.The connection to the database is done correctly, as I am able to return data with various other queries.

I am using VB 2008, then I noticed that with the Provider.Oledb.12.ACE = database.accdb whatever connection string uses the bin/debug/database.accdb file when I connect my program with a database. Suddenly, a database with the same name appeared on the lets say "WindowsApplication1" folder. Then whenever I try to debug/run, it throws an error saying that it was unable to copy the database from the "WindowsApplication1" folder to the debug folder even though VB 2008 reads through the database from the bin/debug folder. As a result, after I input values when I debug, it resets because VB 2008 copies the database from the "WindowsApplication1" folder.

I'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.
I have a little problem with converting data from a datagridview to my access 2007 atabase.t's been some years since the last time I've opened Visual Studio 2008. So, probably it's something easyo do.
