just if you are using Microsoft Access Data Connectivity Components 2010 in your application to read data from mdb access files, you might get unexpected exceptions and your application will crash!To reproduce this behavior the best way is to run my sample application which will allow you to see the bug directly in no time.This behavior may occur at any time, any where, but I found if you use Application.DoEvents, you increase the chance to run your application to crash.To reproduce ::
1. You should not have any Office version installed on your system (I am using Windows 7 x64).
2. install the Microsoft Access Database Engine 2010 x86 (or x64 and you'll have to set your project to x64).[URL]
3. Download and run my sample application in VB.NT 2010, and press the button, you will get it [URL]Where is Microsoft going, do you think?Should I hope to receive an official response?
I have a vb.net 2005 application that connects to an access database. I use Access Database Engine 2007 to connect to to this database.
Everything worked fine until i install MS Office 2010. After this, the application started to crash, returning the error 'application has stopped working'.
I've a Windows Seven Enterprise SP1 32bits.
When i debug the application, visual studio also crashes. I get the following error, closing an OleDbConnection: 'vshost.exe stopped working'.
I decided to run some tests. I installed my application on 2 virtual machines: a windows xp sp3 and a windows 7. When i installed ACE 2007 everything worked fine, but when i installed ACE 2010, thats when the problems began. This behavior ocurred on both machines.
I am trying to deploy a VB2010 programme that uses the 2010 Access Database Engine. The programme falls over when starting, with an error trying to access the Database. If I Install the programme on a machine that has Office 2003 installed - still installing the 2010 Database Engine - then it runs OK.Does the Database Engine work?
I have an access database that has nested queries. For example, the querydef below is called qs_Pedon_type: SELECT qs_Pedon_basic.peiid, metadata_domain_detail.domain_id, metadata_domain_detail.choice, qs_Pedon_basic.siteiidref FROM qs_Pedon_basic LEFT JOIN metadata_domain_detail ON qs_Pedon_basic.pedontype = metadata_domain_detail.choice_id
It used to be that the VB6 installation tool automatically recognizes a MS Access dependency and includes the appropriate DLL(s). In VB.Net (2008) I am struggling with the concept of having to have two different installations, one for my tool and one for the 2007 MS Access Database Engine... Can you tell me if there is at least a way of manually including the appropriate Database Engine Files in my application installation?
I've installed the Microsoft Access Database Engine in order for an app to read and update and Excel file using OLEDB on a 64bit operating system. It all still works fine on 32 bit however i get a "Failure Creating File" error on a 64 bit machine.I'm using the following connectionstring(VB.Net) as per [URL]:
icant conect to database with visual basic i get this error "The Microsoft Office Access database engine cannot find the input table or query 'Puna'. Make sure it exists and that its name is spelled correctly"
Here is my code :Public Class dataLayer Private Shared connection As OleDb.OleDbConnection Private Shared Sub connect()connection = New OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & IO.Path.Combine(My.Application.Info.DirectoryPath, "Fiskal.accdb") & ";Persist Security Info=False;")
this is my code for adding users in my database but it has an error on the INSERT INTO statement.here is the error: Microsoft office access database engine: syntax error in INSERT INTO statement.
vb.net Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click Dim conn As New OleDbConnection(cn) Dim check As Integer
I am using VB .Net to connect to an access databse when using several connection sometimes i get this erro "unspecified error microsoft jet database engine" even though i am an administrator on my local machine.
I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?
I am developing a software that connects to a database and manipulates product and user data. It works on my computer but it will have to be used by many computers maybe even world wide (who will access the same database) so I have no idea what kind of systems people will have. I still don't know how to ensure that they will be able to connect to the database for I have already had problems in Windows 7 computers which don't have jet oledb.4.0
I am a bit lost here because I don't know if I should first try to do a connect, or if I should first look for a jet oledb engine on the computer where the software is installed. And in case they don't have it installed should I prompt them to install it before running the program further? Or should I pack the engine along with my program? What is the line of thought here to make the program run on (almost) any machine?
I coded a program to access a Microsoft Access 2010 database. The program is written using Microsoft Visual Studio 2010. I get the error message that the database I'm trying to access is in an invalid format. look at the code below to see what I missed. The error is in the datasource statement.
I'm using old DAO 3.6 to connect Access database (with mde extension). App works fine on XP and on Win7/Vista when UAC is low/disabled. But when UAC is on I get following error: The Microsoft Jet database engine cannot open the file 'C:ProgramDatacompanydb.mde'. It is already opened exclusively by another user, or you need permission to view its data. [code]
I have an error to go mad. My vb.net application makes a report that runs fine in my local machine (with vs2003 and SQL Express 2005). My problem occurs when I execute this using an external database (SQL-Server 2000). Then my app returns the error "Query engine error: "c:....".The actually data origin for report is a dataset, and I've compared the two datasets fill
I have been visual basic for sometime now and I want to develop a quiz engine that uses database to retrieve question. I also want it to be able to save users name.
i'm pulling my hair out on this one. the error i'm gettting is: The Microsoft Jet database engine cannot open the file ''. It is already opened exclusively by another user, or you need permission to view its data.
I'm trying to import data from an exel sheet to a data grid but I keep on getting the following error "The Microsoft Jet database engine could not find the object"
Here is my code

quite new to database queries through VB. I have just created a DB using MS Access and I need to write data to it from my VB Application.Can anyone point me on which objects should I use to execute these write transactions?
I have a program that prints using the printdocument control. How do I check for errors in the program. Sometimes the program prints ok, sometimes the print does not print at all or give any feedback about the status of the print.
Bireirectional printing is enabled on the printer.
The program prints barcoded orders to a barcode label printer. The supplier's only cue to supply is the printed barcode label. I can see in the program that the orders are getting queued, and at certain intervals a timer runs to update each available order's status to "printed".As far as I am aware, there is no "Error" event of the printdocument control, and the printing is an asynchronous operation. So how should I check?
[URL]...From this link, it explains the formula of how getting the critical level of the products, but I can't imagine how to automatic-compute it because every month and every year there's a computation to be done
I found with cheat engine the adres of the code the enables and disables a checkbox in another program ( value 0 and 1)But which code will this be to make a vb.net program of it
In my projects (WPF) I use System.Windows.MessageBox to show the user a confirmation dialog for operations that are critical, such as a delete-operation.
My problem is that if I specify as button value MessageBoxButton.YesNo, the user cannot use the escape-key to cancel the operation. IMO this is one of the most annoying things, a program can do, showing a dialog without the possibility to cancel/close the dialog through the escape-key.
Other possibilities are MessageBoxButton.YesNoCancel, but IMO this is confusing because it shows three buttons for only two operations . Or one can use MessageBox.OKCancel, but this is IMO not clear enough. In my dialogs I want to ask the user if her really wants to execute the operation. And for this, a simple ok is not appropriate. A yes (I want) is much better than an ok (go on).
How do you handle this? Is it a non-topic or do you think as I do and have an own MessageBox-implementation or do you know a possibility to extend the System.Windows.MessageBox-class?
it's just for a program registration. i would store all of the registration codes in the access database, then export it to XML, then upload it to my web host. I would then somehow connect it to my Visual Basics login form (Which I have already made). If this can't be done, having them register through the form and having all the allowed codes on the internet (So i can easily edit them)!
I programmed an app with an Access 2010 database, I installed the app and the database on a computer with office 2007. The app can't open the database. Do I need to copy some extra file on the user's PC?
