I am using VB .NET 2005 and I would like to compact an Access 2003 database.I've read "How to compact a Microsoft Access database by using Visual Basic .NET" from the knowledge base but it will only save in Access 2000 (link below).Attempting this with a 2003 database throws an exception about not being able to save it as an older version (losing features and what not).Is there a way to do this with a 2003 database? url....

View 1 RepliesI'm using the Microsoft Access Database Engine and trying to do a compact using the following code:
Dim acc As New Dao.DBEngine
Try
acc.CompactDatabase(serverDataPath & "MQRMeta.accdb", serverDataPath & "MQRMeta.001.accdb")

My VB.NET program compacts and repairs my DB, but somewhere in the process unsets the database password. No problem, just reset it through VB, right? not sure how to go about that task.
So I either need to know how to compact it without losing the password, or how to reset the password after I lose it. Trying the best I can to make the code look decent in my post, let me know if there is a better way.
Dim strAccessDatabasePath As String = System.AppDomain.CurrentDomain.BaseDirectory & "App_DataSquirrel.accdb"
Dim LockedDbFileInfo As New System.IO.FileInfo(strAccessDatabasePath.Replace(".accdb", ".laccdb"))

View 1 Repliesi Have Used Database file for storing Data in my Application.Now I want to take backup of data in Access, Excel or in Any other Format.
View 1 RepliesI am using VB2005. I am trying to write to an Access database seperate from the data's origin. AKA: I need to run a query getting data from one Access table and write it to a table in another Access database.
Overview: I need to get data from one Access table and two Excel worksheets. I need to write the data to an Access database so I can run a query combining the three into one table. I will then use the table to create reports.
I have googled, checked multiple sites, and checked MSDN. The only thing I have been able to find is populating a datatable and writing changes back to the database. This was SO easy in VB6.
I have a Visual Basic 2008 Windows form application that processes some scores and data. I want to export the data to an Access database. I have created the Access database and connected it to the VB program.I am looking for a simple set of commands or sample code to add records to the database. Perhaps I am oversimplifying the problem, but it seems like it should be so much easier than it has proven to be. I only want to export the data in code; the user should never see the database or do anything to it while the program is running.

I have an MS Access 2003 database built that resides on a shared network path at the company I work for.The database works perfectly for users connected directly to the company network.However, when a user tries to open the database while connected remotely to the company network (they can still access the shared path), they receive the following error:The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.At the time that they tried it, they were the only person accessing the database.They tried a local copy as well as a copy on the network shared drive.[code]
View 4 RepliesThe Calendar control (the Month Calendar) control in VB 2008. I am creating an attendance timesheet and I want the Calendar to color each date differently like e.g An employee Paul is selected from a list.
On the calendar I select the month. (The dates are not supposed to be selectable). Then lets say it is June. He is late on the 1st and the Second, so those days are supposed to be colored red (the whole block). Let's also say he is absent on the fourth and so I want that date to be coloured black. How do I do this? I tried finding a query and my friend told me that this functionality is not available in the current control and that I was best off making my own control (???).
I have tried selecting specific dates and bolding them (there is a function that allows this) but I am stumped trying to find two different ways to differentiate colours. Second:- How do I link a calendar with an Access Database?

I've got this program I'm working on in VisStudio2008. Basically, it accepts a password and executes an Access 2003 database using the Access 2003 runtime. I've got the thing looking up a password and all is good, but there's one problem those annoying Access 2003 and higher warnings about unsafe macros. Does anyone know a way to make sure those don't show up when the program starts?My client has a database that someone else wrote for her. She's not at a point where she could have it rewritten (believe me, I've tried to talk her into that). So I have to stay in Access but it's not very professional to have those warnings come up.

It runs without a problem in VB 2005 IDE, no problem at all. However, when I compiled it, and build the set up, and deploy it. It throws up this exception:

I have VB 2005 windows application that is reading and writing records into Access 2003 database. After I deployed application to multiple servers - the database stays locked all the time - even if nobody has it open. When I check open files through Computer Manage - it doesn't show that anybody has it open. Yet - I can't delete .ldb file, I can't repair and compact the database to replace existing database, I can't rename database to replace it with other version.

I have an application that is currently using DAO and would like to move it to ADO.Net. The problem I'm having is that when I do, I cannot do any queries that take variables if the database is Access or SQL Server Compact Edition. For example: SELECT RecipeName FROM tblMasterRecipe WHERE CategoryID = iCategoryID..The database is a local standalone database. Of course if I use the Standard SQL Server I can add parameters just fine using the TableAdapter Query Configuration Wizard. How do I do something similar for Access or SQL Server Compact Edition? The Create new stored procedure radio button is greayed out when the database is Access or SQL Server Compact Edition.
