Losing An Access DB Password On Compact : How To Reset From VB
Jun 9, 2011
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? Ummm... 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.
Dim strAccessDatabasePath As String = System.AppDomain.CurrentDomain.BaseDirectory & "App_DataSquirrel.accdb"
Dim LockedDbFileInfo As New System.IO.FileInfo(strAccessDatabasePath.Replace(".accdb", ".laccdb"))
Dim TempFolder As String = System.AppDomain.CurrentDomain.BaseDirectory & "App_Data emp"
Dim TempDB As String = TempFolder & " emp.accdb"

I made a password protected program, but I wanted to make a reset password via security code. I made this, but it will not work for some reason. It seems like it'll work for the first time, but then when you try to set the password, it stills shows that the password is there and when I go into the reset password form and do it again, but then it say its incorrect.
I am trying to compact a Access 97 MDB file. I have found and tried the following code
Private Sub CompactDB() Dim jro As JRO.JetEngine jro = New JRO.JetEngine() jro.CompactDatabase("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<DATAPATH>", _ "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<DATAPATH>;") MsgBox("Finished Compacting Database!") End Sub
This codes works and seems to compact the file and it appears in the destination folder but when i try to open the new file i get an error "Unrecognized database format 'DATAPATH'"Is there something i am doing incorrect? the database file sizes range from 5Mb to 100Mb+

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'm updating an old VS 2003 project to VS 2010. Part of the application uses the old JRO COM object to compact the database. That seems to be depreciated in 2010.
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 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....
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.
Previously this was not problem on XP/Vista (with minor changes), but windows 7 (64bit), is having issue's and I thought it might be how I'm implementing this time around? This is the original version just gives a com exception error of {"Cannot create ActiveX component."} [Code]
Ok, so I am building my own program to control a video player I have through telnet, I have everything else working except one thing.I have a reset button to reset the player, when I press it, it sends the string "Reset" and the unit resets without a problem.But when I add a code to close the winsock connection upon reset, it doesn't send the string to the unit. I am sure what is happening is the winsock is getting closed at the exact same time it is trying to send the string and so it fails to send, how do I make it close winsock AFTER the string has been sent?
