Writing To A Local Database?

Jan 27, 2011

I'm currently under way with a computing project for 6th form and I have encountered a problem when working with a local database.

To give an overview:

-My program is intending to take in data on lorries, drivers and other sections of the haulage industry through multiple forms and afterwards be returned in a suitable manner.

-I have no trouble in reading data from my database that I have set up. However I am unable to write back to the database.

-I can add the relevant new data to either the specific table(Driver_Table in this case) of the Database1DataSet.xsd or to a table set up in this manner.

-My problem is with the Driver_TableTableAdapter.update method.

-When I call this it returns a value of 1 (for one row added) but does not write this to the database.

In specifics the particular section (created to test this section of code) is:

'Dim tbl As New Database1DataSet.Driver_TableDataTable
Driver_TableTableAdapter1.Fill(Database1DataSet1.Driver_Table)
' Driver_TableTableAdapter1.Fill(tbl)

I am trying to write data back to my database in my project, but it keeps disappering when I make any changes to code. I can build the project, add data, close the project and build it again and the data is still there. But as soon as I make any changes to anything, on the next build, all of the data is gone.

The table will not be bound to any controls in the final project, but for testing purposes I have a datagrid control that it is bound to. My code started as follows:

Writing To A Database Instead Of Text File?

Apr 3, 2012

I am creating a fault tracker AKA issue tracker. It is going to be very simple in functionality. As of right now I am using a text file as a database for the end user to store current issues.

The reason for me using a text file is that I do not know much about database programming and I cannot find any simple examples in the same usage. My question is, is it really going to become a problem as more issues are added to this file and it becomes larger? I.E using up more resources, application getting slower etc?

If so, could anyone point me in the right direction to creating a simple database application. Most examples I have seen require ask to download their pre-made database. Although I would like for the program to create a database if one is not there.

Writing To Database/Datatable In Simple Project?

Then, the user clicks a button to add all this data to the datatable via a newrow. The second form includes a datagridview to show the datatable. However, I cannot get the code below to work to update the datatable. I have a button to click to check to see if the data is entered and it returns an error that no row exists.

Writing To SQL Database Manually (for Education Purposes)

Sep 18, 2009

I'm building an application that is intended to function off and online using the new Local Database Cache functionality included with Visual Studio 2008. My issue however does not pertain to that directly, as I have a pretty good understanding of how to use it and how it functions. My issue is with getting an understanding on how to directly write to a SQL database.

Most of the tutorials, videos and education available when it comes to databinding makes the assumption that I need my application to pull data and edit it, but in my case all I really need (in fact intentionally all I want) is for the application on Submit to write data that it pulls from the form as a new record in a SQL table.

Here is what the program looks like now.

Public Class StatCom
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

[Code].....

At the moment the program simply does a status check for connectivity and wether it can ping the server (in this case the SQL server) for the purpose of displaying a online or offline status in the form.

I follow it up by making the status checks.

Finally I declare all the various fields I want to capture and write to the database.

What I want to do now is have a SUBMIT button that on click takes all the data in the form and writes a new record to the database I have already setup and have data connection to.

I know that the code has to be written using the .recordset functionality, but I haven't found any could tutorials on the subject that have turned on the light upstairs.

DB/Reporting :: Writing A Program And Loading Info Into A SQL Database

Feb 17, 2009

I'm writing a program in VB.Net and loading the info into a SQL database. Debugging it works fine on my machine that I am programming it on, it connects to the database and runs through all the info perfectly. However trying to get it to run on another machine it will not connect to the database. I realize the reason for this is the connection string, it's looking specifically at the file directory for the database. How do I change this so that it will function on any machine. The program is only intended to run on one machine at a time and not over the internet.

Designing The Flow Of Code When Reading / Writing From Database

Aug 8, 2009

So I'm trying out a concept tool of mine where I need to be able to read and write data from a database real easy. I've set up the form as I like and spread around different text boxes and dropdownboxes to read the data from the database. And I've got it all to work and all, but there's a small bug I don't fully understand why's there. Some textboxes don't update the text from the database.

But it seems as it only occurs if the data in the database is nothing. So the value from the last row is still hanging in the textbox and thus, clicking "Update" actually updates the value from the field from the last row, into the new row. Messing everything up.

Interaction With Database (Reading / Writing Tables And Fields)

May 2, 2012

Using Visual Basic 2008 express, I would like to access a database with 2 tables, one table (useraccounts) which has Users and Password and ID, and the other table which has information (linktable). Basically I would like to do a login form which reads from the table useraccounts and be able to create new users which will write into the database.

Another is that I have a form with a number of links which I would like to store in the table 'linktable' and it basically just gets the links from the table and straight to the form where it is used. I have tried using access or the .mdf files that visual basic has but I have been unable to find an answer for either.

I wouldn't mind using either access or the .mdf file for the database, I would just like it to work. Overall I am trying to get:
Login form which reads from database table 'useraccounts' and has a new user feature
Just a form that can read / write to the database once the save button is clicked.

Writing One 2D Array Onto Another?

Sep 7, 2009

It would be easy enough to make my own system for this, but I'm figuring that the .NET library, being as massive as it is, probably already has a class made for this very purpose.For hit detection, my VB.NET game uses two 2D arrays that store the state of each pixel in the level. Each element in these arrays is a Byte (or, more accurately, a value of a flag enumeration type based on Byte).

Public TiHD(,) As HitDT ''//State of each pixel in the level based on
''// its underlying tile.
Public SpHD(,) As HitDT ''//State of each pixel in the level based on[code].....

I would enjoy being able to just give each sprite & tile its own 2D array of hit detection data (defining which pixels of the object are solid, dangerous, etc) that can be directly written to TiHD or SpHD at a specified offset.I'm willing to bet that .NET has a class that can do this for me.Presumably I would just have to pass TiHD or SpHD to the constructor, and then I would be able to use the object to indirectly modify the array with extended functionality (similar to using a Graphics object to modify a Bitmap). Is there such a class?
