Locked Access Db - Can't Compact Or Delete Ldb
Aug 23, 2007
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 want delete all files in a folder, but I get access denied as the file is locked.I use an email function before i'm trying to delete the files, the send email is a built in function of the application:fcMailer.SendMailWithAttachment Process.Company, "email", Subj, "Bo", "e:upload est.xls" i tried to set it to nothing: set fcMailer = nothing and set fcMailer.SendMailWithAttachment = nothing I'm using the below to delete the files
[code]
Const DeleteReadOnly = True
Set objFSO = CreateObject("Scripting.FileSystemObject")
objFSO.DeleteFile("e:upload*.*"), DeleteReadOnly
[/code]
How do i remove connection holding the file or simply just delete all locked files / or not locked?

I am having some issues with an application written in VB.net.
As part of a routine, an sqlce database gets backed up before the routine then if an error occurred gets restored. I am using system.io methods copy and delete.
I have released all the objects (connections, commands, datareaders) asscociated with the sqlce database by disposing them if they are not nothing. I also do a GC.COLLECT however when my delete command runs, an error message says it is open by another process. The PROCEXP.exe process explorer tool says it is attached to 4 undefined processes. After a while in debug mode, these clear and I am able to delete the file. However this is not acceptable as my program cannot "wait around" until they are released! I was under the impression that object.dispose forced an immediate disposal rather than waiting for the garbage collector to clean up (if you were just to use object=nothing), but still there appears to be a finite time before these objects are released.
My question is, is there an alternative way of checking (programatically in vb) for what is holding open an sqlce database (or in fact any other file for that matter) then killing these processes?

my problem today is the following:
Setup: 10 pc's connecting to a shared hard drive on a server connecting to a certain .mdb file from access 2003
Problem: We are a 3rd party tool for a Point of sale application and when the real software makes some modifications it locks certain tables which we don't lock. My ( Might be possible solution ) is: Is there a way to check with a query or an certain object if the table is locked if yes

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+

I have a compacting subroutine which basically call for MSAccess compacting[code]...
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:
"Could not load file or assembly 'Interop.JRO, Version=2.6.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified."

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.

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"))
Dim TempFolder As String = System.AppDomain.CurrentDomain.BaseDirectory & "App_Data emp"
Dim TempDB As String = TempFolder & " emp.accdb"

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.

My program writes to a .txt file (and this is the ONLY program that writes to it) in a thread (with lowest priority), but every now and then it gets an error "The process cannot access the file because another process has locked a portion of the file" when it executes this code: swLog.WriteLine(sPacket).Other program reads from the file, not write to it, why do I get this error, and how can I get around it, or what shall I do when I get this error since I can't write to the file ?

I'm creating an application that adds and deletes records from a microsoft access database. The language I'm using is VB2008. I am importing the database through a wizard. I can add records and delete records, but I cannot delete a newly added record without closing the form first. When i reopen the form, I can delete the record. Here is how I have my database setup:
'Bind user info to the controls.
AUSERDataSet = New BulldogUsersDataSet
AUSERTableAdapter = New BulldogUsersDataSetTableAdapters.UsersTableAdapter
AUSERTableAdapter.Fill(AUSERDataSet.Users)
' Setup the binding source.
AUSERBindingSource = New BindingSource

how to do it, but the tutorial is not applicable on the program that I wish to do. The tutorial tells you to add 4 navigation buttons so that you can navigate the database(first, last, back, and forward). Then an update and delete button. But if this is what I will do, it would take 10 years to navigate the database and update a record. Now, what I want to do is just for the user to input a unique ID and click search button(which I have already done). Then the update would be easier. How can I update or delete a record using this method?
