VS 2010 Save Data In Two Related Tables
Feb 16, 2012
I have a database created using sql server express 2008. There I have two tables called tbl1 and tbl2, which are related as tbl1.CityNumber=tbl2.CityNumber.
I have created the programme using VB 2010; there, a form has three textboxes.
Tables: tbl1,tbl2 ; (related as tbl1.CityNumber=tbl2.CityNumber)
Columns to be updated:tbl1.CityName , tbl1.CityNumber, tbl2.StreetName
TextBoxes on the VB form: txtCityName , txtCityNumber, txtStreetName
[Code]....
But, now the problem is, the two tables have not get updated,after going to the database in MS.SQL Server Management Studio. I think I'm very closer to have my required result. I have tried my best to track place,where I've gone wrong.I have been trying to find a method for last five days.

I have a Microsoft Access database that has one-to-many relationships. When I created the tables for the database, I did not enter any data into any records, as that will be done by the application user. My problems is when data is entered into the parent and child tables, the parent table data is the only one that gets saved when clicking the save button on the binding navigator.If I have the parent and child tables data entered the same way a user would prior to connecting the data source and add EndEdit() to the child table BindingSource in the BindingNavigator click event, everything works exactly the way I want it to.This application is a data entry form, so it wouldn't make sense to have to have data entered in tables prior to adding the data source to my project. What is the best way to create a data entry form with one-to-many relationships? [code]

I am trying to produce a form in VB2008 which shows data from two related database tables, and then allows the data in one of the tables to be updated. I would like to do this using a DataGridView, but I have no idea how I would go about this.

I have a simple "two-tables" database (SQL EXpress) and a very simple application (VB 2008 Express). The two tables are customer and order and their structures are:
customer(IDcustomer, LastName, FirstName) IDcustomer=primary key orders(IDord, Number, Description, IDcust)
IDord=primary key the tables are related (IDcustomer-->ID cust)
In VB2008 environment I create a dataset, by means of Data Source Configuration Wizard, which encompass both customer and order tables (xsd file). By opening xsd file I set the relationship in the following manner:
"Both relation and foreign key constraint"
Update Rule = Cascade
Delete Rule = Cascade
In my form I show customer table in detail-mode and orders table in datagridview-mode. Two Fill method are created in the Load event and they work correctly.In "CustomerTableAdapter" I create, with QueryBuilder, a search query (say LastName query) and I write the following code:
Private Sub frmSearch_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.CustomerTableAdapter.FillByLastName(Me.CustomerOrdersDataSet.custom er, "D") 'All Lastnames with first letter = D

I am having a problem saving related tables and querying them. I have both data binding sources on the form and I have both being added, end edit, and both being saved. When I "view all" and click on the related table "crimes" they're not showing with the Inmate that committed them. I have gotten it to do this with a code similar to that below and I am wondering what I'm doing wrong so that the datagridview for crimes will display the correct crimes for the correct inmate. The primary key for inmates is DOC# and the Primary Key for Crimes is "Entry ID"
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Me.Validate()

I have two tables < student > and <class> . In vb2008 i make the connection to the database, display the data in both tables, edit existing data. The problem is that when i try to insert new rows to both tables there is a problem when i try to save both tables at the same time. The save button is in the studentBindingNavigator. I connect to the db through the Add New Data Source. The message i get is Can not insert or change a record beause it requires a relevant record in table student. Does anyone know anything about it?The two tables are related to each other.

I dragged 2 tables onto a form, the nav bar at the top showed up, but it only saves data for one table for some reason - how can I make it save data to both tables at the same time? I looked up the properties, but I can only select one dataadapter

The StudentDetails.Students is the master table which forms a relationship with RegistrationDetails.Registration. Therefore, StudentID is the primary key in the former whereas it is a foreign key in the latter.Now I've tried each of the following codes but each of the first two gives an error message "Incorrect syntax near 'a'" and in the case of the third one DbTransaction as in "Dim trans As DbTransaction" is also not a valid type. I'm using SQL Server 2008 Professional Edition.
cmd = New SqlCommand("DELETE FROM StudentDetails.Students a, RegistrationDetails.Registration b WHERE (b.StudentId=a.StudentId) AND a.StudentId='" & txtStudentID.Text & "'", cn)

I am developing a Windows Form Application against a SQL Server relational database. An example of the database schema is:
TableA
------------------
PK A_ID uniqueidentifier
A_NAME varchar(254)
[code]....
In the form I have a ComboBox (cboA_ID) to select the TableA record (DataSource = TableA, DisplayMember = A_NAME, ValueMember = A_ID) and a TabControl where controls on each tab are bound to fields in either TableB or TableC.My question is, is it possible to bind cboA_ID to TableB.A_ID and TableC.A_ID?This is my first database application so if there is a better way to do this I'm all ears. I have set everything up using the wizards in Visual Studio 2010, so I'm still not 100% familiar with what all the various TableAdapters and DataSets do.

I have never worked with datagridview before. I need to know how to use it so i can use it in my (calculator) program. I would like to know how to make columns, rows, linking the cells in the table/grid to textboxes so values entered into the textboxes (on the calculator) after pressing save goes straight to the table.

I have three tables under one database. I'm using the built-in Navigator control for now until I get this figured out, but I'm using a button command instead of the built in navigator button. I need the "Save" button to save the data in the text fill boxes to save to the corisponding table. I used the drag and drop option to drop rows from each table to the form. See code:
Private
Sub Button1_Click(ByVal
sender As System.Object,

I have one DataSet and two forms, Customers and Efficiency. When I make changes to the Customers table (Delete a Customer for instance) It does not reflect the changes on the Efficiency table. The default form is Efficiency and I'm calling the Customers form from within the Efficiency form. I make the change in the Customer form, I then close the Customer form and call the Efficiency form back. The data is not updated on the Efficiency side until I close the application and re-open it. what code I need and where to inject this code?

I have written lots of code with the ADO Library in VB Excel and previous versions of Visual Basic. With the dissappearance of the recordset object, how do we perform data manipulation with an attached Access Database? It seems things could be a lot easier, and less complicated by now, however, the best methods appear to currently remain ellusive.

I have looked at the answers in the forum and some seem dated. I an an old vb2 person and need to move up. I understand sql very well and use complex queries. First test project and trying to add multiple tables to a data grid (Only Form in project).I used the Data wizard to add the Access data base and worked by way through to near the end. The query works in the wizard and returns the correct rows. The error message is "The solution returned by the new query differs from the base query."
During the creation process I selected all the tables. Reading some of the old anwsers I get the inpression that VB 2010 does not handle multiple tables in a datagrid (forum items go back to version 2008).

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

I have two data tables. the second related to the first. Using a datagridview for the first table I am able to enter and save data ok. if I run the code twice in a row the data is still there. When I edit the data in the related table in it's own datagirdview the data is there and displays correctly, but on running the code a second time the related data is lost. In both cellendedit events I am using
Me.table.Update(Me.FigsDataSet.table)
Me.Validate()

I have a datagridview bound to a bindingsource. Two of the columns contain values that link to the primary keys in other tables. Instead of displaying the primary key values, I would like to display the name of the item associated with the primary key. In other words, the primary key value may be 3 but I want to display "Furnace 5" in the datagridview instead of 3 (which it is now displaying).
