Currently I am writing a code using VB.net 2008 to display changes happen in an access 2002 database mdb file. The mdb is using by another program for input and i have no access to that program source code.Currently I am using timer function in my program to get latest data from mdb file. Is there any other solution can use to monitoring the database for any changes on table data.
Thanks for any tips and help.

thanks for your time good people!
I am adapting an Access 2010 client to work with a new SQL Express Server 2008 back end. The back end is up and running. No problems there. Filestream is configured and working fine.
My problem relates to acessing the filestream BLOB data I've stored in the SQL Express Server 2008 instance from my client. Specifically accessing the data through the win 32 OpenSqlFilestream API as detailed here: https://msdn.microsoft.com/en-us/library/cc645940.aspx
I know I cannot access this API within VBA. I have to write all the relevant code in a different language. Therefore I plan to write a mini-program in VB.NET which will consist of a pop up form that allows users to add, edit, delete etc the files stored through filestream.
I want to open this mini VB.NET program from within Access 2010 as a pop up form.
How do i do this? I have never written or compiled a program in vb.NET, furthermore I don't know how I can then call this program from within my VBA code in the Access 2010 client.
Please help.
Thanks,

I have an existing Access database that has out grown it's usefulness. I have written a Visual Basic program that uses a SQL Server database and have been re-entering the data from the Access file into SQL Server individually.
I still have 300+ records to move and would like to find a way to do all this using either a data snippet in Visual Basic, or using SQL Server Express. I'm smart enough to set up and use Access, and smart enough to create a program and database in Visual Basic and SQL Server but for some reason I not smart enough to move the records between the 2 databases.
When I originally created the .mdf file I attempted to move the records at that time but everything I tried didn't work so I figured I'd get it later, but now I have 300+ records in the .mdf file and need to get the others moved over. Anybody have any ideas?
Easiest thing to do is create your database, then in SSMS's Object Explorer, right click on the database, Tasks -> Import Data ... and go through the Import/Export wizard, selecting MS Access as your source.
I am trying to make an application in VB6.0 using MS Excel as database. I have some textboxes on my VB Form to take input from user. I want to store those values in an Excel file. There will be another form where I want to retrieve the values from Excel and display it in textbox/labels.
Can I use SQL queries for inserting/retrieving the values while using Excel as database?
I just need a sample code for understanding the process. Rest I will try to manage.
Thanks in advance.
It's a poor idea.
While you can treat an Excel workbook as a data source via the Jet IISAM or ODBC Desktop Driver this is really meant for simple importing and exporting and has numerous limitations.
Save yourself some grief and just use Jet 4.0 to create and make use of MDB files. No MS Access is required, Jet 4.0 comes preinstalled and has for a rather long time now.
I am making a small application that will read .csv files into a newly generated access table (generated with vb.net), I am filling this database with sql and now I would like to output that table as a .dbf file!
I can't find any info on this subject.
I know some of you will tell me to just make the script in vba in access, but there are some functions that require me to use vb.net and the client wants a single .exe file.
There is a forum post here that includes some VB.NET sample code to create a .dbf file and write some data into it. The code uses the Visual FoxPro OLEDB driver (VFPOLEDB) which is no longer distributed with Windows by default, but can be downloaded here.
How might one backup and restore a Microsoft Access database, using VB.NET?
Backing up and restoring a native Access database is simply a matter of copying the entire database file (.mdb for Access_2003 and earlier, .accdb for Access_2007 and later). You could use VB.NET for that, but any scripting language would work, even a simple Windows batch file that does something like
copy /Y d:\apps\databases\mydatabase.accdb z:\backups\databases\*.*
