How to Query multiple tables in a dataset to form single consolidated table without using any external database. I know this can be done using 'JOIN' in SQl.
Now my condition is I have multiple tables filled with data in a dataset and each table is interrelated with a common 'column'. For example ,
Table 1
ID
Name
1
[Code].....
Here I mentioned only two tables but in my case there are many tables. I need a generic answer for this dynamic query .

So I'm not familiar with much vb code but I was hoping someone my spell out something pretty generic as far as updating a database. I'm pretty sure I've successfully edited rows but when i'm using my database update i get an error, probably just incorrect syntax. This is what I have so far...

I have a form in vb8 that is set up as follows:
I have a table in my Access database calledUsers that has a name and a password (encrypted).
Using the toolbar I created aBindingSource with a name of UsersBindingSource and a dataSource ofUsers
Using the toolbar I created aDataset called with a Name and a DatasetName called Users_Dataset
Using the toolbar I created atableAdapter called UsersTableAdapter
I added two textboxes on the form and changed theirDatabindings...Text property to the corresponding field in the Database.
How to now update the database when I click Update. What the program needs to do first is encrypt the Password before saving it. I wrote the code in the TextBox2.Lostfocus event to encrypt the data a place it back into the TestBox2 field. The only samples I find on the net refer to DataGridView controls (which work) but I don't want to use them. How can I get the database to accept these changes as well as changes to radio buttons or comboboxes?

I am currently developing an application that is linked to a MS SQL Server 2008 Database. So now I realised that I needed to make a few minor changes to the database (add new columns to some tables, change the data type of a few columsn in some tables). After making the changes, I realised that these changes have not been updated in my VB application's dataset. I then tried to "refresh" the dataset, but it still is not updating the dataset. What do I need to do to update the dataset to reflect the changes in the database?

I'm developing an application where depending on a textfile input i should update/insert some data into an Access database. Let;s say I'm updating the bookshelf of a book according to a textfile that goes like:
TEXTBOOK | BOOKSHELF
000000001 | 000000000A
and so on
[Code]....
does that make any sense? What I'm trying to do is basicalle: check if a book exists, if yes, then attach to Dataset, change its Bookshelf to the one in the textfile and repeat until the file is completely read. The Bookshelf can or not exists, if it doesn't then it should be inserted, is it done automatically when I update the Dataset? Finally "Batch update" the whole Dataset.

I'm fairly new to visual basic and have a problem that is probably quite easy to solve yet I have been unable to do it so far and am about at wits end.I have an access database with a table that contains a list of cities and states. what i would like to do is to populate a combo box on a vb form with a list of the states in the states column. the query that i have is as follows:
SELECT DISTINCT State from Cities I have previewed the data in the dataset designer and it works, i just can't figure out how to make it fill the combo box. i initially created a table with just all of the states and then used a binding source and table adapter to bind it to the combo box, but if I'm able to figure this out this would help with my application going forward

I am connecting to a web service that returns a dataset that I use as a datasource for a windows client datagridview.
Once a user has made changes to the datagridview record(s), how do I get those changes back to the connected dataset and back to the remote database.
I wrote the sql update function in the service:
Code Snippet from web service
<WebMethod()> _
Public Sub Update_equipment_repair(ByVal repair_id As Int64, ByVal date_entered As DateTime, ByVal date_sent_in As DateTime, ByVal date_returned As DateTime, ByVal damage_description As String, ByVal vendor_id As Int64, ByVal repair_description As String)
[Code]....
This displays the records perfectly and I figured out how to delete and insert records via web service.

I have an application that performs database queries using "Imports System.Data.SqlClient". I want to display an animated GIF on the taskbar which spins while the query is running. However, during a query the application simply hangs and does not update the GUI until the query has finished, at which point the spinning icon is set to invisible anyway. Is there any way to force the GUI to update while the query runs?

I am new to ado.net and I am trying to learn capabilities as much as get this particular task done.Let me set the stage for my question.My goal is to load up a dataset, write out an XML, transfer the file to another machine, read the XML back into a data set, load up the local tables, find missing records from the local database and add them.These tables are for employees. There is the 'Employee' master, "Employee Job" the employee job code, and "Employee Hours", the employee time punches.I thought I could treat a dataset as a database and do SQL queries against it.For example to find missing Employee , my thought was to do a outer join on employeeID and look for null in the second table.Something like:

I have been searching for quite a while about joining multiple datatables via LINQ to dataset (When i say multiple, i don't mean just 2!!!), and it seems there aren't lot of examples in the net. I have seen examples of joining two datatables, done that, no problem there. Now i want to join three datatables. And there's nothing i can find out there.For example i have a 3 datatables:
PERSON (columns: person_id, name, gender_code, ethnic_code)
GENDER (columns: gender_code, gender_description)
ETHNICITY (cols: ethnic_code, ethnic_description)
