Oledbdata Or Table Adapters Dont Update Database?

Jun 22, 2010

I have a problem that hopefully someone can shed light on. My OleDBdataadapters and OledbTableadapters have gone on strike In a simple vb.net 2005 pro project I have an Access 2003 .mdb with 2 tables each with 1 primary key and all other fields allowing zero length and not required. The database (not read only) is included in the project (see connection string below which works because data is presented on bound forms).

Although each table's data is displayed on one of 2 bound windows forms, it just refuses to update, add new or delete. I've deleted and recreated forms, etc, using wizards and just run time code but the problem is still there. I can change data manually in the mdb. The code below refers to a site mdb table and was wizard generated. I added an update query to the TableAdapter using the wizard, see sql below.

Access Database - Setting All Bindings And Table Adapters

Feb 24, 2009

I have a project that I used the 'Connect to Database' tool to set all the bindings and table adapters, etc. Currently the database is housed in the same directory as the exe. I was asked if I could have the database location be a dynamic value. My question is when you set up a project to work with a database using the 'Connect to Database' tool, how can you change its location?

I found this setting:
ASRDBConnectionString
But its read only.
Within that setting is text that says: DataDirectory
So thought that might be a variable to change somewhere....but can't find it.

Continue Using Table Adapters?

May 3, 2010

I recently created a test VB.NET 2008 project with an Access database and it seems to work okay. It uses a dataset and table adapters. I'm aware that some people don't like table adapters. I'm willing to learn another way if it's better. Should I do this or continue using table adapters?

Adding Table Adapters For A Different Dataset

Feb 19, 2009

How do I do this for a different dataset? I'm trying to rule out database problems so I made another one and added it, but now I need a table adapter for this one instead of the old database because it keeps giving me an error. I don't see any place to add them and I'm getting extremely angry at these databases.

Find All Table Adapters On A Form?

Aug 14, 2009

You can iterate the controls collection and me.components.components to find certain objects, but nowhere can I find where a form keeps a collection of its early-bound table adapters. When you add them in at design time and bind them to a control, it shows them on the design window, and it creates them in the design.vb file, and they're available as a property of your form object... but I can't find a way to browse through them and pick one in code, like you can with the control collection (I.E. me.controls.Item("controlname")).[code]...

Using Table Adapters To Insert A New Row Doesn't Do Anything?

Apr 1, 2011

I'm using visual studio 2010 to build my application and SQL server 2005 to store the data. I created a table adapter, dataset and binded the controls to my already made formThing is, i'm trying to insert a new record into the database and it won't work! I can fill the form with a record from the database and update it so i know its definitely connected correctly. Everytime I try to insert a new record whether its through a table adapter or manually, I just can't seem to get it to automatically save to the database.Ive put this under the save button

Private Sub SaveBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveBtn.Click

Table Adapters And Updating Multiple Tables?

Apr 21, 2011

Using; - vb2008 Express, data on ACCESS 2003, objective; - to update a separate table not on the original query.From what i have gathered i need to add a second table adapter to make the changes to a related field in another table. Since i already have the 1st table adapter the second does not appear as easy as the second (dragn the data set over).

So i suppose i need to create the second table adapters programmatically? [URL]..I see that because they are not nested they need to each be declared.. right? If so that is where my issue lies. I'm having a problem with how to declare them both now that there must be two.

Apr 14, 2009

I have inherited an application at work that someone else started creating, right now about 1/2 of it is functional and is in use.

Determine If There Are Data Changes To Save / Update Back To A Database Table?

Feb 2, 2012

I'm using VB 2010 Express with a local Access DB. I am having trouble determing whether there are changes in a DataGridView to save back to the underlying DB.

The DB has been copied to the project directory and its properties (by selecting it in the Solution Explorer) include Copy to Output Directory: Copy Always, so I know that any changes I make when running a build will disappear on the next build. The problem I'm having is within a run / test session, working with the application.

The Access database has the following connection string, with Application scope:

Provider=Microsoft.Jet.OLEDB.4.0;Data Source="|DataDirectory|Component MI.mdb"
