VS 2005 Checking Database For Row

Apr 25, 2009

I have a program which is almost complete, it gets data that is new or newly modified (well at least since my program last got this data). The problem I have is currently i'm adding this "new" data but i've just clicked some of this data may be in my database already just updated. For example, I have added some user data to my database but a user has just updated their user name - so this is now newly modified! I don't want to add it as new data I want to update my current row in my database. My question is how can i do a SQL query in my access database to see if this row exists or not?

Checking For Result From MS Access Database?

Nov 24, 2009

In my .NET application I have to manage bookings for rooms. I enter the room booking via an SQL query to a MS Access database using an INSERT INTO statement.

Before I insert the booking, I need to check if a booking already exists for that time period, and if it does stop the user from being able to book at that time.

I have written code to retrieve a database result on the day and time of the booking they want to book, and the fact that Access would return data would mean that the user is trying to book over someone else.

how I can check if I have a resuklt returned. My code:

cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=D:Databasedatabase.mdb;")
cn.Open()

[Code].....

But this doesn't work, it displays the messagebox regardless of if there is a row returned or not. How can I check if a row was returned?

Developing An Access Database That Will Be Shared With Multiple Users?

Aug 22, 2008

I am developing an access database that will be shared with multiple users.I don't want the users to access the database directly so I will have them enter new data on a data access page. The data access page is stored on a Microsoft Share Point web page, and the database is stored on a network drive.Here is my problem: When new data is entered on the web page I need it to trigger a WillChangeRecordset event; however, I have not been successful because the web page does not declare a new instance of a recordset object.At a minimum I need the new data to be processed before the web page appends the new data to the table.

Possible To Have An Access Back-end Database Available For Multiple Users On The Same Network?

Nov 5, 2011

I am developing a Visual Basic .NET application to be used by the staff of a small training centre nearby. The front-end (UI, menus, etc.) will all be in VB .NET, and there will be a back-end database for storing all of the required data, such as student records and meeting information. What I would like to know is if it's possible to use a Microsoft Access database for this purpose, and have it accessible by all the staff in the centre (on the same network) at the same time. For example, would I be able to put the database in a shared network folder, and have a copy of the VB application on each PC that would all be able to read/edit/add to the database?

1.I�d like to publish a free vb.net desktop application for the users to download and use meanwhile I�d like to collect usage information ex: user ip address, user�s registration information, used features, time spent� if the user allows the report to be sent back.

2.Also , in order for the user to be able to use the application, he�ll have to register it then, everytime, before the application loads, it gets verified online that it was registered, maybe validate the registration information or a valid user name and password, no critical personal information. The target of this step is for the application to be used exclusively by the registered user and maybe on his computer only.
