I have a .mdb (Access) file that I am using in my VB program. The program is basically just querying out data from the file. I prefer to update the database through access and then my vb program will just automatically be up to date upon saving the .mdb file. I have a data connection connected to the .mdb file and using the data set on my form. For some reason when I update the .mdb file, the program will not be updated with the new items....even if I right click and refresh the data connection and data set.
Is there a way I can fix this so that when I wont have to worry about deleting the connections and resaving in VB and creating an executable. I'd prefer my end result to just always work upon the .mdb file being updated.
When adding the connection and dataset there is a part that prompts you about it being a local file and if you want, you can have a copy saved to the projects directory. Clicking no will make sure that the local file will be used and not the copy in the project folder.

how can i make to automatically every day run my excel file, reload data from db and append in existing data.
Do I need to use vba script or...???
I have an idea that might work,
Write a script in any backend language of your choice (Java, Python...) that creates an active connection to the database
Run it to periodically query a database table(MySQl,..) and store newly entered data into variables
Continuously append that data into the excel file as you normally would any file.
Most languages have packages to handle excel files, I think it should do it.
Good luck
I am creating a library application in Visual Studio 2010 Professional and Access 2010. I bind the Access database to Visual Studio. When I fill out the fields and click submit I can see the new record in the DataGridView, but when I close the application the new record is not saved and I have to input the record again.
Can somebody help me to know why when I input the new record through the application the record is not saved in the database?
It is a very common situation. You have your database file (the MDB or ACCDB file) listed between your project items. If you click on this file and look at the properties window you will see a property called Copy to the output directory. If this property is set to Copy Always then every time you start a debug session the database file listed in your project items is copied by VS in the output directory (usually BIN\DEBUG). Of course this copy doesn't contain the records inserted in your last debug session and you think that your previous insert has failed.
Setting this property to Copy If Newer, the mentioned behavior will happen only if you change the database schema manually.
Setting this property to Copy Never, will let you manually copy the database file.
So basically I made a FamilyTree Program using MS Access DataBase. I want the user to be able to 'Export'(Copy) the Access File and be able to 'Import'(Replace) it in the program after it's already built. I tried looking for this but all I get is how to do these things as a programmer and not a user.
If anyone could point me in the right direction, I'd be grateful :)
Just close the connection to the file and do a simple file copy.
To restore, copy the backup file overwriting the current file.
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.
I am about to release some reports in Access 2007 and I need to lock down the Queries so that no one can change the queries does any one know how I can do this in Access 2007?
Please Note: Simply adding a GUI and hiding the "database window" is not enough as people can still get in with the right key stroke etc.
You could Make an .ACCDE, and give that to your users to execute.
You can create an .accde file from an
.accdb file by clicking Database Tools
on the Office Fluent Ribbon, and then
clicking Make ACCDE. When you create
an .accde file, Access compiles all
the code in the database and strips
the editable version of the code from
the new .accde file. This process both
reduces the size of the resulting
database and guarantees that no one
can change the original source code.
When you open an .accde file in
Access, the form and report designers
and the Visual Basic Editor are not
available. In addition, you cannot
transfer forms, reports, and modules
to another database by export or
import.
However, since an ACCDE is apparently less secure than its predecessor the MDE, your best bet might be to convert the database to Access 2003 format by using the Save As command, and making an MDE from that. If you open an older .mdb file in Access 2007, a Make MDE command appears on the Database Tools tab instead of the Make ACCDE command that appears when you are working in an Access 2007 database.
In Access, if you click the Windows button and then Access Options, then Current Database, you will see options to disable navigation and keyboard shortcuts.
