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.

View 6 RepliesI 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.

how to connect database in vb.net using msaccess
View 1 RepliesI'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'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.
View 13 RepliesI'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

View 2 RepliesI 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.

View 2 RepliesI'm using Visual Basic Express 2008 (VB.NEt). I've created a project which
connects to a Microsoft Access Database (OLEDB) & displays the records using textboxes in the windows app.
I need to add a button which exports the database to a fixed length text file. Does anyone know the code I would use to do this?
Those who are looking for an example like this, might find it useful (or not). I know i was looking for one like this for over a week. Ok now, to make this codes work properly, you have to make a Database in Ms Access (I used MS Access 2007) . Create a table of two Columns, one name Debit and one name Credit. Both of the Columns Data Types must be Long Integers or you might get some conversion errors at run time. Now save the database in Access 2000-2003 Database format. And last of all, put the database in your projects DebugBin directory to avoid the database Connection Errors.

I'm new in VB.net but I'm trying to make application (planning-game). The game is about showing students the planning 'complexity' of a operation room in a hospital. I created a listbox which randomly shows 5 operations. But now I would like a function which makes it possible to add a selected operation to a timetable. The timetable has blocks of 30 mins (example 08:00 - 08:30, 08:30 - 09:00 etc..). This because 1 type operation takes 1 hours and 1 takes 1:30 hours. Now I have given the operations a value by using a label. [code]
