No Access To An Mdb Database File After Copying The File?
May 21, 2009
I have the following code where I make an copy of my database that I use. the code executes 100% but the problem I have is I'm not able to access my database afterward.I get a "Cannot start your application. The workgroup information file is missing or opened exclusively by another user." and so if I restart the application it all works fine again.I'm certain the reason is because I can only access that database using a specific account name and password which is not account I'm logged in with.What i want to try is to default that database mdb to the point where no user is accessing it, or to reassign the the only account name that can access it to that database mdb. I've tried playing around with file security but had no luck.
Private Sub cmdBackup_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdBackup.Click
BackupDialogDB.DefaultExt = ".mdb"

I have an application running access constantly whilst using it. I was hoping to backup the file each time i close the application. What checks do i need to do to make sure when i close the file that it is safe to copy the file without getting errors for copying a file when still in use.

I am using .net 3.5 and vb.net 2008 I have a program that copies access databases (.mdb) over from one server to another to be used ofr a ArcGIS webservice. The databases are edited on one server then nightly copied over to the webserver so they can be consumed in an intranet page).
The program is just a windows form that runs copy command in the load procedure. The program itself is run form the scheduler as an admin user for the machine but no one is actually logged in when it runs at 1 at night. I then get this kind of error reported to me:

I've got an app which uses a background worker to copy files. It works fine but some files are quite large and it "appears" as though the app isn't doing anything. Is there an alternative to the File.Copy method of copying files so I can report on the progress of individual file copies, like the percentage complete?

So, I have a task where I need to basically copy about 600,000 PDFs, some of which can be 5-6 MBs from one network fileshare to another network fileshare on another pc.Now, I crawled through the directories, sub-directories etc etc and created what I call a Filename/Filepath Database lookup table. This table contains the name and the unc fileshare path of each file which comes in handy.I have used Multi-threading and File.Copy to "copy" the files and I getting about 45K files per 4 hours which I need to be significantly faster then that and I am seeing performance degrade over time

Friends I have Developed my Data base Project on vb6, using adodc and datagrid using ms access database file, it was working nice in vb6, I also put Search box there and used adodc1.recordsource="select * from table" sql query.
later i needed to convert it in vb.net I converted it, every thing is working fine, but one problem appears, an adodc's Recordsource query for searching records is not working, it only works if there is data in dataset (Datagrid),suppose once i pressed search button to search record and if no record found then dataset / datagrid becomes empty, now i wanted to search an other record with other name, but this time it does not work and following error appears Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

I have a workbook (Workbook1) that runs through some steps using visual basic, which ends up opening another workbook Workbook2). Once Workbook 2 is opened, I need to copy a section of data from it, into Workbook1 int a specific worksheet. I was able to do this by recording a macro, but the challange is, the name of Workbook 1, and Workbook 2, will vary by User. When I created the macro it uses the files as they are currently named. The section of code is below.

I recently made a small exe program that connects to an Access database.Now it runs fine on most computers, but the one it HAS to run good on has some pretty harsh restrictions set on it's network.The problem is an OLEdb connection is refused because the file is not trusted on the Network, and I don't know how to give it the access it needs.I've tried running an install with it, and that will give it access, but only on the local computer and not on the network drives.I've tried placing the database in the network drive and accessing it with the install there, but there is a problem in that the local drives are wiped at logout.I've tried giving it trust access through Administrator Tools, but it always throws an error when I try it.

I use the following code to import a XML file into an Access database:
dbname = "c:PC Auditer.accdb"
xmlFile = strFileName
Dim ds As New DataSet
Dim streamRead As New System.IO.FileStream(strFileName, System.IO.FileMode.Open)
ds.ReadXml(streamRead)
streamRead.Close()
[Code] .....
The import works fine, but when a next XML file is imported with less records, the database don't get updated and the 'old' records remain in the database.

My problem does not seem to be the same as in other links. I'm trying to teach myself VB 2008 and I want to connect to an Access MDB file. I follow the instructions in all the different books and websites. I start a new project, choose a new data connection, change the type to Microsoft Access and browse for the file. When I get the connection string I press "Test Connection" and it's okay. I then drag either the entire table or just a field to the form. I use Data Preview Data and can see all the rows and columns and the data, so I know the connection has been made. however, when I press F5 I get a form, but no data and it says "0 records of 0".
I accessed the code and put a MsgBox before and after the "Fill" statement. The one before pops up, but the second one (below Fill) does not. I also get "A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll" in the Immediate Window. I have tried putting a "Try" statement around the code and in this case it will go to the second MsgBox, but still no data.
I'm following what seems to be the most basic and simple method, but I cannot get data in my form.
