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.

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.

I'm trying to set up an installer to register a web site. Currently, I've got it creating an Application Pool and Web Site under Windows Server 2003. Unfortunately, whenever I try to modify the ServerBindings property to set the IP Address, it throws an exception at me. I first tried this because the documentation here told me to [URL]. I'm currently using VB.NET, but C# answers are okay too as I need to switch it over to using C# anyway.

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?

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.

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]...

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
Dim CustomerRow As accountingdbDataSet.CustomerRow

On the update line i get an exception thrown up "A first chance exception of type 'System.Data.OleDb.OleDbException' occurred in System.Data.dll" I thought inserting a record into a database would be easy but i seem to be naking a right pigs ear of it?

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.

I would like to know if it is possible for a Table Adapter to reference a query as opposed to a table. Currently my Table Adapter references a table in my SQL database, but I wanted to know if it was possible to have it reference a query, which selects a table from another database?

In a project, I have a dataset with two table adapters. Without warning while I was modifying one of them in design mode, I received this error. I have typed the contents of the dialog box exactly as they appear - so no additional information was given, and the error code was "-1".

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. My problem is that it is all done in 2.5 ?? and I am trying to step through it all to figure out how it works. I have always created my own binding sources, adapters and data tables.
One of the things I need to do is add a field to the fm_fieldman_master data table. I add the field in the db (SQL Server 2005)table, I come into VS and refresh the datasource, I then add the field to the fm_fieldman_master data table and the Fill,GetDAta() query I go into the designer and create all the attributes for the combo box

Im currently making a program. It loads data from database fields into an combo box. Everything works so far, It just seems to be a mess. Do i need to have all the datasets and data adapters? or can i get away with just using 1 of each. It seems like im doing it wrong, and although it works it seems like a difficult and messy way of doing it.
Also i would like to assign the firshermenID to a variable depending on the fisherman name that is selected in the combo box. When button is pressed: id = fishermanID of the current fisherman (cmbFisherman.text)

I have two Access database, say database One.mdb and Two.mdb. I want to use VB2005 to export tblCustomer from One.mdb to Two.mdb, and replace the existing tblCustomer in Two.mdb, during run time. I basically want to simulate the export function that is available in MS Access (which can export one table from one Access database to another) with VB2005 during run time. I can think of a way by querying the table to a dataset and then delete everything on the other database before filling the table in that database with the dataset

I need to Update Access Database Table with Data from a Different Table. Not all the rows of original Table to be Updated will be affected. How do you loop through the 2 Tables to do the required Update.
The Table to be updated is called "RecordList" and Table with new Data is called "RecListReport".Every attempt I've made won't work. I tried to Use 2 Datagridviews but couldn't get it to work right.
NewTestConn()
Dim Testconn2 As New OleDbConnection(NewTestConn1)

I have a table in a database that I need to access. At the moment I am trying to get the Table information to go into a dropdown box. I know how to open a database but I don't know how to open a SQL one. Also when I used VB5 I used to "Set" the database to open. When I type "Set" it comes up in the blue letters and then disappears. Has Set changed to something else?

I have an Access database with some table and some queries.Here you see one query which returns 2507 records:I also added this database to a vb.net project.However, if i try to fill the datatable of the query with the specific tableadapter, the datatable stays empty. Also when I click the query in the dataset and choose 'preview data' I get none of the 2507 records:Any idea why he won't load the records into the dataset?

I have an access database (made by other application) that I need to read it. The problem I have is that the tables I need to read do not have the read permission; the access permission is set to "Share Deny Write"; though I can open the database in MS Access and export the table to another mdb where I can read it. Is there any way to automate this, or to set read permission on the database using VB.net? Is there any other way to get the info from table not having the read permission?

How would I do this? I have no code at this time for it, but how could I do this?
I have an Inventory table that contains a lot of Trash Containers (Construction Dumpsters).
All of these containers have a field in the table for their "Size". If I wanted to quickly change all of the price for all Trash Containers that have a Size "40", how could I loop through the table and for each container that has a size of "40", I want to change the price lets say from $100 to $120.
