When I update a record at table [Product] with the integer that stands for [Supplier Name] from joined table [Suppliers], this does not appear in my datagridview. Instead, I have to reload the table to dataset to make it visible. What about datarelation? Is it better that loading a joined table over the dataset? Note that I have never dealed with datarelations before.. How can I make a datagrid column to show "Supplier Name" instead of recordID that represents this supplier?
View 2 RepliesI have multiple tables that I need to pull and display data from. I have created a new query in the TableAdapter of one table to pull data from related tables based on a parameter. In the Query Designer I can run my query and see all of the columns requested in my SELECT statement, however when I bind this table to a DataGridView and call the new query, it only returns the original columns from Table1.How do I see all of the columns I selected in my query?

Can i insert in two tables data with one insert statement in .net VB 2008?
View 1 RepliesI am using VB 2005 professional and SQL Server 2005 express edition.
For the last two weeks I have been trying to have a datagridview control on a form that will have datasource from a dataset with two tables that are related. I want child the column to be a ComboBoxColumn where userts can select options and update the other data(from the other table).
I have two tables in an sql server 2005 database named computers:-
computers
locations
Table computers looks like thisID is the primary key column)
ID Location
Computer139
Computer240
[Code].....
With the location column being a ComboBoxColumn so that when a user enters a new ID say Computer5,they have a choice of a dropdownmenu for the Location column. In the database table computers the item should be saved as well as the index value(to correspond to the LocationID).

I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.
Dim
SQLconnect As New SQLite.SQLiteConnection()
Dim SQLcommand As SQLiteCommand
CODE:.....................
my code: command1.CommandText = "INSERT INTO table1,table2(value1...,value2..)VALUES('" ...... "')" how to save multiple table is one query? i tried this thing but it didn't work

View 1 RepliesI would like to know the best, or standard, way to accomplish real-time client updates in a small multi-user application using an access data table as a data source.Specifically, this application will be used by 3-4 people. It uses a datatable which is filled on form load and bound to a datagrid at design time. The datatable is stored on a shared drive. The data table on the shared drive is updated in two ways:
1) Users can update the datagrid which then updates the datatable on the shared drive via the data adapter's Update method.
2) A server application does some work on some text files, periodically updating the data table.
I need the clients to reflect the changes to the data table on the shared drive as closely to real-time as possible. I know that the data table stored in memory on the client is disconnected from the data table on the shared drive, so I must query again to get the updates.
1) Is there an alternvative model I can use which is connected, and which will automatically reflect the updates in the data table on the shared drive?
2) If not, what is the best way to check for changes in the data table (so I can know when to call the data adapter fill method)? I am planning to poll the drive for a change to the .mdb file, raise an event and then fill the data adapter when the event is triggered. I am using this method successfully now to check for changes to a text file in another application, and I know how to implement it?

I have two data tables within my data set that are loaded onto my form on form_load using statements written in code (not the designer. When I change a value for the first table via a text box the change is made to the data set. But when I try the same for the second table, the change doesn't remain in the data set when I switch to a different company and come back. I query the second table using the primary key of the first table but no code is needed when I change the values for the first table so I don't understand why the same doesn't work for the second when I change a value via a data-bound text box....

'This is used to read our data from the data base

I need my application to be able to update the DataGrid, and commit those updates to the database. My problem is that all the research I've done so far has led me to believe that there's no way I can do this because the SqlDataAdapter.Update() method only updates 1 single table.I just had an idea to make my event handler execute a stored procedure that creates a view on the database, populates it with data from my dataset, and then distributes the information between the two tables where needed.I guess another solution would be to use 2 DataGrids and then tie each of them into a seperate DataAdapter/DataSet, and then update each when the Event is called. The problem here would be that it's more work for the end user to make changes, so I'd really prefer to do it another way.

if it affects the run time of a program if I were to have multiple data tables as opposed to one data table with all my data in it? I am trying to minimize datagrids and just use code to access table data, in hopes that it will speed up my program. But I am ignorant if multiple tables vs 1 main table will make a difference because there will still be the same amount of overall data present in my program one way or the other....?
