View 2 RepliesI'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.
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")
Catch ex As Exception
PrintLog(modName, rtnname, "Error compacting database. " & ex.Message, "MQR2500E:")
End Try

View 3 RepliesMy 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 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"

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]

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

"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<DATAPATH>;")
MsgBox("Finished Compacting Database!")
End Sub

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 am looking for some sample code to use in VB2008, in order to compact and repair Microsoft Access MDB files and ACCDB files.
View 1 RepliesI 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.

View 2 RepliesI am new to vb 2008 and I can't seem to figure this out.
When I try to add a database to my project I get this error (Please look at .jpg (Firsterror)
I have selected the correct driver SQL Compact 3.5
It will add the database to the project but the FULL PATH is always incorrect and I can't change it. (Please look at my seconderror.jpg) the correct path is C:SQLSample.sdf
I have the following code which I hoped added a row to my DataGridView and also a record to my database. It does the first part, but not the second.
Dim row As DataRow = Me.CCLogDataSet.tblLog.NewRow()
row("cc_log_contract") = Me.txt_Log_Add_Contract.Text
row("cc_log_registration") = Me.mtb_Log_Add_Registration.Text.ToUpper()
row("cc_log_milage") = Me.txt_Log_Add_Milage.Text
[Code] .....
It seems to be storing the data in memory? As the data in the DataGridView is persistant, even after a Relaunch of the application. However, why I query the database, there are no records in it.
Is there a way to write an application in VB.NET that will create a Compact 3.5 database on my desktop and then fill it with data from a SQL 2000 database?

I want to use VB2005 to export tblCustomer from One.mdb to Two.mdb, and replace the existing tblCustomer in Two.mdb, during run time. I basically want to simulate the export function that is available in MS Access (which can export one table from one Access database to another) with VB2005 during run time. I can think of a way by querying the table to a dataset and then delete everything on the other database before filling the table in that database with the dataset
