VS 2010 How To Essentially Set Up / Create Tables And Modify Data Within An SQL Database

Mar 24, 2011

I've been into programming, I've landed a job with a local company, the entire project the gentleman is paying me to do is incredibly easy, with one hitch, the original project I'm converting is built using access databases, for efficiency, and easier online transfer, I'm wanting to switch to using an SQL database, I've got plenty of experience inserting, modifying, and controlling an access database, but where should I start to learn how to essentially set up, create tables, and modify data within an SQL database?

Timeout Using SQLite - Create A Database And Several Tables - To Populate The Tables With Data From Arrays

Jul 25, 2012

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:.....................

SQL Data Access: VB2008 / VB2010 - WinForms - Create A Datasourse And Drag / Drop Fields Or Tables On A Form To Create A Grid

Oct 22, 2010

I have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).

My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own
both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.

Then I would have to create an Event table with the ShipmentID as a foreign key and fields like Source, Code. Basically a field for each node. Then if there are columns in the table that are new, I would have to modify the table and add the column. I only have to create tables where there are child nodes or where the nodes have attributes.

C# - Gathering Data From Tables Of Access Database

Mar 2, 2010

I want to gather some data from some tables of an Access Database, I've found some solutions online, but I haven't found ways to fill a datatable, or dataset, and get each single field properly. Is it easier for me to get whole tables then get just the info that i want, or should I make a lot of searches in the access DB getting just what I want each time? Any code snippets for it? The Access Database is in an ACCDB file, with no user or password. I'm currently using VB.NET, but it doesn't matter if you answer in C#. [URL]

Displaying Data From Tables Of Database On Form Labels

Jul 14, 2009

I am new to the forum and I was wondering if anyone would know how to display data from the tables of a MS Access database on labels on a form. The code underneath is my code for saving inputted data from textboxes.

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
objDA = New OleDbDataAdapter("SELECT * FROM CDetails", "Provider=Microsoft.Jet.OLEDB.4.0;Password=;" & "User ID=Admin;Data Source =" & Application.StartupPath & "CustomerDetails.mdb")
objDS = New Data.DataSet()
objCB = New OleDbCommandBuilder(objDA)
[Code] .....
I would like to show these saved details onto another form. Is there a way to select rows and cells in the database and fetch the data in them to display them onto labels?

Entering And Saving Data From A TabControl To SQL Database Tables

Jan 31, 2010

I am developing a program that will contain a TabControl on a form. The TabControl will have multiple TabPages that will represent forms used in the mental health field by clinicians. What I have done so far is created a SQL Express 2005 database that contains a table for each TabPage. To start off, I am working with only 2 tables to see if I can make this work. The tables are called EvalPage1 and EvalPage2. Each table includes a field called ClientID which I have named Key Indexes. I am also using these fields to create a relationship: EvalPage1.ClientID (Parent) and EvalPage2.ClientID (Child)

The problem That I am encountering is when I use the BindingNavigator to enter and save a record, it only works for EvalPage1 and not for EvalPage 2. Here is the code that I am using:

Public Class MainForm
Private Sub EvalPage1BindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles EvalPage1BindingNavigatorSaveItem.Click

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 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?

VS 2010 - Trying To Build Button To List All Tables In Database

Oct 27, 2011

I am trying to create a button on a form that will open a connection to a database and list all the tables in the database inside a listbox. Everything I have read indicates I can associate a single table to a form, and have no idea how to:

a. Create code for the button to access all the tables in the database.
b. Display that list in a list box.

The text that I am using is murach's ADO.NET 3 database programming with VB2010, and I am less that thrilled with it.

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.

Multiple Tables In Visual Studio 2010 (VB) On Data Grids

Feb 13, 2011

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).

<item>[code].....

Say if a user created an item with the name 'papers' and due date 'Tomorrow', I need to be able to make another list element like above and insert it before the </list> tag. Basically I'm asking how can I write to my XML file at a specific position (at the end before the </list> tag)? Is it possible just to go to the end of the file and go back a line?
