When Adding Or Modifying Table Adapters In A Dataset.

Apr 17, 2008

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".

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.

Filling Dataset With Adapters?

Jun 23, 2010

ok normally when i fill data i do it this way adapter.Fill(dataset, "table1") However instead of using Strings, i prefer using enums so for example i have:

public enum Tables
T1
T2
end Enum

but since adapter.fill does not provide an "integer" argument when i add i had to convert it to a string as such adapter.Fill(dataset, cstr(Tables.T1)). i find this "dirty" and was wondering if there is a better fix

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?

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
Dim CustomerRow As accountingdbDataSet.CustomerRow

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.

VS 2010 Table Adapters Based On Query?

Mar 17, 2011

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?

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.

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.

VS 2008 Binding Source/Data Adapters/Table Adpters?

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. 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

Adding Columns And Modifying Columns In Access Database Using NET/SQL?

I am using the following code to alter an table imported from an Excel spreadsheet

Dim SQL As String = "ALTER TABLE receipts ADD payee integer, account integer, category integer, reconciled boolean"

dataread.Connection = Connection1

[code]....

Both ExecuteNonQuery() actions yields the exception message {"Syntax error in field definition."}The error message does not happen with the first if the boolean column is not there (I tried Tes/No as a definition - but that also failed.The second query to modify the ID column from autonumber to integer I assume fails because it is a Primary KeyHas?

Update A Single Table Of A DataSet Using A TableAdapter Without Hard-coding The Table Name?

Nov 13, 2009

I have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.

What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:

Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter

What I'd like to do is this, but of course it doesn't work:

strTableName = "tlkpMyTable"
Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")

Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!

C# - .NET Dataset Design - Have A Dataset For Each Table?

Jul 23, 2010

I have some concern about designing Datasets. I was told that it would be good to have a dataset for each table for maintenance purpose. Because frequent change in database tables is expected, having one dataset including every tables would be pain to make the corresponding change in the application.

Q. is it good approach to have a dataset for each table ( I would end up having 30~40 datasets for each db table using Stored procedure) ?

I have a separate project for commonly used datasets. each project include "dataset project" as a reference, and use it by including needed dataset into Forms, classes, etc.

Q. Does this approach makes the whole system to be slower? If I have a set of datasets as a separate project, it would be beneficial, since It will be easier to make a change (I only need to make modification in one place)

There can be multiple of the same order number. In the dataset, I want to have a column "line number" and I want to put in it the value of the linenumber (in this case 1 and 2) per order. In sql , I was able to accomplish this by inserting rownumber() and grouping by order number. Can this be done in .net?
