View 4 RepliesI'm trying to insert and update from a table in MSAccess I've declared everything: Connection, DataAdapter and Commands.I didn't use the Command Builder instead I supplied my own Queries.My problem is if I add three rows to my table all the three rows in my database have the same values from the first row. It seems like the parameters are stuck on the values from the first row. [code] I'm using a DataTable with my DataAdapter since I'm dealing with a single table.I'm filling the table with a parametrized query, and updating it with the same dataadapter.I'm adding rows to my datatable and manipulating the table through code. I know that my data is there and every row has it's own values, I can see them when I debug my program.

How to insert record date in my access db. I am using hdate as my field and his data type is short date
Here is my code
cmd.CommandText = "INSERT INTO hold ([hdate], des) VALUES (#" & myDate & "#, '" & TextBox1.Text & "')" cmd.CommandText = "INSERT INTO hold ([hdate], des) VALUES (#" & datetimepicker1.text & "#, '" & TextBox1.Text & "')" cmd.CommandText = "INSERT INTO hold ([hdate], des) VALUES (#" & DateTimePicker1.Value.Date.ToShortDateString & "#, '" & TextBox1.Text & "')"

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)

1-KH01-tes
2-KH01-test
3-KH01-testing
SQLServer (" KHang" : Id-MaKH-TenKH)

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 6 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.
