Deployed MSAccess Database Not Updated Through Application?
May 26, 2009
I've created a VB.NET Windows Form application which pulls info from an MSAccess database via datasets and tableadapter. When the user makes a change to the data, I use the Update method of the tableadapter to send the changes back to the database. This all works fine in the Visual Studio 2008 IDE, but once the build is done and the application is installed, I run into problems. The application keeps the original data and will not read or write to the database, although any changes I make through the application are mysteriously saved somewhere. If I make changes directly to the database using MS Access - which I need to be able to do - those changes don't show up in the data pulled into the application.

I want to compress an ms access database using vb.net. If the database is open this fails. How can I close the database, compress it, then reopen the database using vb.net code to accomplish this. I've already successfully written the code for compression, but I can't find anything on closing the database while leaving ms access open.

I am calling a stored procedure that calls a bcp command from a visual basic 2005 application to export data to excel. When I publish the app on my machine the procedure works fine. However when I attempt to install on another users machine when I push the button to call the event ..the export does not happen. I am trying to install from a network and the other modules work fine.

This may be a dumb question, but I am stumped. I wrote a simple desktop application in vb.net (vs2005) and published it via the "deploy" method. After I deployed the app and ran the deployment exe - the application runs fine. However, I have recently added some command line switches so I can run the app via a scheduled job. But I cannot find the "exe" file in order to run the application from the command line. Am I missing something or did I deploy/publish the application wrong?

I am new to ClickOnce deployment and at first glance it seems a great way to maintain .Net applications updated with ease. I am developing a simple application that stores information on a mdb database and over some XML files. I understood how to use the "data" folder with ClickOnce and I am developing the part of my application that should migrate the data from older versions after a ClickOnce update. Now I need to debug that part of my code that only runs when the application is in "networkDeployed" mode. So actually I'm doing the following really slow process to test a new deployed version:
publishing the application on a provisional website (I can choose between a faster locale iis site or a real online one) installing the application from the deploying website (the first time) or running the old installed application so it automatically catch new updates and gets updated... running the application
So basically I have two problems here:
the whole process is much too slow :/ I'm running the app as every other app directly from the OS, so I can't access to the debugger...
I am pretty sure that there are better way to test ClickOnce deployed applications...

I have migrated a VB6 application to .Net which uses the MSFlexGrid in a total of 7 different places on 3 forms.When the compiled application is installed on a non-development PC, one of the forms throws a LicenseException when trying to create the instance of the MSFlexGrid control.The other two forms successfully create and use the MSFlexGrid instances that they contain.The problem doesn't occur when the application is run on a development PC.[code]I have looked at the designer.vb code for the forms, comparing the instances which work with the one that doesn't.In both cases, (working and failed) the same calls are made to the control wrapper (i.e. a new instance is created, BeginInit() is called, attributes are set, it is added to the containing control, and EndInit() is called, where the exception is raised.To reiterate, this is not the 'usual' problem of a missing developer license.The exception is not occuring during development, it is occurring in the application installed in the production setting.

I have a smart client application deployed as a click once application called "PDFSplitter". The link to install this PDFSplitter is on our company intranet and when you click the link you get a "The publisher could not be verified. Are you sure you want to run this software?" message. Is there any way to make this message go away?

I have recently finished a console application and deployed it to several computers on our network for testing. As it is just an EXE a copied to the hard drives of selected computers for now. When the app is launched it writes info to an sql DB so I always know which computers it is on.
During the past few weeks I have modified this app at least 6 times (improvements, adjustments, etc)
It is a paint to keep going back to the computers to update it with the new version, and getting mixed up which version i am on - LOL I am looking for advice on how I would go about doing this automatically, for example, it would be cool if I just had to put an updated file in a repositry and clients would use this to update.
In Visual Studio, when I view the properties of my application>assembly information - I can set a file version. Is it possible to extract this info and store it in a variable? I would like to dump the in my DB. Also I could then possibly compare the file version of the launched app against an updated file in a network share folder.

I have the following set of code for a Sub program. It's inserting a row into a MSAccess Database using data provided in the containing form. What I would like to do is grab the ID number of this added record so that it can be set for a property of a window that is invoked when successfully added. I tried looking this up but I get something about @@IDENTITY but it's using an entirely different way of connecting.
Private Sub CreateTournament_Click(sender As System.Object, e As System.EventArgs) Handles CreateTournament.Click
' TODO: Check the form for errors, or blank values.
' Create the tournament in the database, add the values where needed. Close the form when done.

I'd like to make a little vb.net program that executes searches on a msaccess database. I use a textbox to get the value to search and than i'd like to search all the values that has the textbox value in the middle. So, the queries should look like this: SELECT Rec1, Rec2, Rec3 FROM Table1 WHERE Rec1 LIKE "*" & txtTextBox.Text & "*"...My problem is that i don't know how to pass the "*" character to my query, if I build a string that i pass to OleDbCommand(), the query returns nothing.

I'm updating an app for children I wrote in VB6 to VB2010. It uses a rather extensive MSAccess Database. It works perfectly but I need to update it to utilize better speech technology. I have read a lot about SQL and can't find how it is useful for anything accept business applications that add, delete or update records as long as you hard code in a name. I don't use datagrids and I never display a table. how to do a few things, I can figure the rest out.
In VB6, I had:
Option Explicit
Public db As Database
Public rs As Recordset
Public Reader As Recordset

I have the same table in SQLServer and MSAccess database named "KHang" with fields : ID int identity(1,1) primary keys , MaKH char(4),TenKH varchar(50)
Here is my data :
MSAccess (" KHang" : Id-MaKH-TenKH)
1-KH01-tes
2-KH01-test
3-KH01-testing
SQLServer (" KHang" : Id-MaKH-TenKH)
1-KH02-testing1
2-KH02-testing2
I connect to MsAccess database using oledb in vb.net and fill data to DataSet1. So I want to update it to SQLServer database. I mean, the result will be like this:
SQLServer(table "KHang") :
(Id-MaKH-TenKH)
1-KH02-testing1
2-KH02-testing2
3 -KH01-tes
4 -KH01-test
5 -KH01-testing

I need to edit and add records to a shared MSAccess .mdb file residing on a server (actually a shared Public folder during development), preferably through an OleDBAdapter or OleDBConnection. I've been able to connect and read data from the database, but receive an "Operation must use an updateable query." error when trying to invoke the OleDBAdapter.Update({datatable}) method. The Update method works fine if I move the database (and connection) to my local C: drive, but fails when moved to the shared folder. Eventually, the shared .mdb file will need to reside on a server after development.
