I have recently just decided to get back into learning some coding and downloaded the MS Visual Basic 2008 Express addition, and i believe this is the right forum, not vb.net.My question is how to open a connection through code to an access database.From what I remember you have to initialize the variables before the functions up top and then open the connection string somewhere. Can someone provide some basic code to open the connection between the form and the database. I am just starting out again and want to basically just populate a combo box by clicking a button, from a table in access with 5 colors.
import.system.oledb >>>>>>>>>>>>?
dim connection as oledb >>>>>>>>>>>?

how can i link form created using vb.net to sql server database.I created a database with sql server 2000 now i want to connect form created in vb.net to sql server database
I'm trying to write a method in VB.net so that when I click a button it queries the database and returns all the values which match a textbox which is located next to the button. I have no idea how to do this, I assume in the onclick method for the button I will need to pull in the value from the textbox, connect to the database and display the results to a gridview?
I got vb.net 2008 express and sql server 2005 and 2008 express editions whic I downloaded from microsoft website.Now I just want to connect vb.net with sql server 20o5 or 2008.I am using a connection string as
PubConnstring = "Data Source=RAMANSQLEXPRESS;Database=FirmTest11;Trusted_Connection=Yes" 'Create your connection object Dim objconnection As ADODB.Connection Dim strSQL As String
[code]....
Getting Error : [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.
I'm having problems connecting to a database. I have sql server 2005 express installed on my PC, and i am using the following to code to connect to it.
Dim nwindConn As SqlConnection = New SqlConnection("Data Source=localhostSQLExpress;Initial Catalog=northwnd;" & _ "Integrated Security=SSPI")
Ok I'm finally getting to put on big boy pants and have now moved beyond doing everything in Access (yay me).o here is the problem, can't connect to the Server. created a test button on my form, which is what I usually do with Access so Ican be sure everything is where it needs to be pointing.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim connetionString As String
Dim con As New System.Data.SqlClient.SqlConnection con.ConnectionString = "Server=iraq\sqlexpress ; Database=stats ; Trusted_Connection=True ;" Dim com As New System.Data.SqlClient.SqlCommand com.CommandText = "insert into users values('" & TextBox1.Text & "','" & TextBox2.Text & "','" & TextBox3.Text & "')"
[Code]...
There are new events happen when i adjust the connection string
con.ConnectionString = "Data Source=.SQLEXPRESS;AttachDbFilename=C:Documents and SettingsAdministratorMy DocumentsVisual Studio 2005WebSitesWebSite2App_Datastats.mdf;Integrated Security=True;User Instance=True"
I am a wannabe programmer but quite new, started with VB.net about 1 month ago.I write on this forum because It's the first time that I'm actually stuck. The problem is I cannot find a way to connect to SQL server database I have created and saved earlier on my HD using visual express 2010. I want to find a way to connect using code, not by click and drop. I just hope you won't find my issue too trivial to even answer it.The project is very simple, it just consists of a button that should connect to the db on click.[code]
It works for a database without password. But for a database with password and the string: "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:DBB.mdb;Jet OLDB:Database Password=xxx"
I get an error:"Object reference not set to an instance of an object." Where wrong?
i'm fairly new to VB and am doing my second system through it. I am at the point where i want to link a combobox on my form to my access database so that when i click the dropdown arrow a list of surnames from the particular table in my access database appears.
[Code]...
First things first is this code remotely close to doing what i want it to do? I have to use an access database and i am familiar with this particular method of connecting to the database (sending any data to it is easy now). Secondly when the form opens (since the sub is called at load) i get the annoying old "object reference not set to an instance of an object" message.
I have a database(.sdf file) in ppc folder - Storage CardProgram FilesEmpEmployee.sdf. I want to connect this file with sql express 2005. I use this code
Dim Con as new sqlconnection Con = New SqlConnection("Data Source= 192.168.55.101Storage CardProgram FilesEmpEmployee.sdf;Password = 12345;Integrated Security=SSPI")
i want to share my ms access database in other computer using LAN so that they have they same database. it is possible?? or any idea that is easier than this?.. my program is just like this. i created a program called ordering system.. the 1st computer will save the orders of the customer and the 2nd computer will retrieve the orders of the customer..
we know that in Visual Studio, you can open a different kind of database: like: Access, SQL server or file, Oracle. is there any reference that you'v know on how to make that kind of program? i don't know where to start.
I am trying to make make a database in vb.net but I am having troble I want to have a form that a user could add and edit columns and rows to the tables in my database. Now a sevice based database would not work on my computer because i did not know how to set up the correct sql sever for vb.net 2008 so I used a Local SQL database i have tried to write some code to connect to it.
i will need further help on try to add the controls to edit the database but i will attempt that befor eposting for help. so here is my connection code i am trying to use a data grid to alow the data base to be edited.
also do I need to add the QNA table to data souces for it to be accessed ?[CODE...]
I have a VB.net program connecting to an Access database. I use ADODB as connection (force of habit, I suppose). The program runs fine on all my machines, but on some of the client machines I get an error on the connection to Access. It is intermittent (sometimes runs without any problems) and happens at different places in the code, but always at the connection with the database. The program connects and closes connections quite a few times during a calculation.
just a few questions. I have read through a of tutorials and snippets on access database.Connecting, updating, inserting, deleting, etc. My main question is this, I have not yet coded the connection to a database using code such as you all. I have always used the wizard to create my connection, table and view this also add the database to the project. Is it better to code the connection, or use the wizard? I have just started creating a program to feed company keep track of there inventory, right now I have 2 tables (feed, misc) both table contain the same things (code, description, price, and quantity). Any way I am getting off the subject, Write the code to connect to the database or use the wizard?
I am trying to write an application, that opens up a specific Access database, change the VBA module slightly, then close the database, saving the changes.Now my code works but it doesn't seem to close Access down very well, causing the following errors:Faulting application MSACCESS.EXE, version 12.0.6535.5005, time stamp 0x4bf5c550, faulting module ole32.dll, version 6.0.6002.18277, time stamp 0x4c28d53e, exception code 0xc0000005, fault offset 0x00047333, process id 0x13e0, application start time 0x01cc5dc3fb9eeb42.
I friend and I are trying to work our way through this, and right are having some issues in terms of getting vb.net to connect to an online sql server. We have found lots of resources to connect to local sql servers but nothing about connecting to an online one. I was wondering if this is possible as we are trying to be build an inventory and pos system for a small company we have, which can be accessed through the vb program from any computer as long as it has an active web connection.
I have created an SQL Server 2012 database using the Server Managment studio and I want to connect to in in VB2010. When I run the connection wizard and locate the .mdf file it always tells me that the file is in use and to close any programs that have it open.
However VB is the only program I have open so I am not sure why it is telling me this order how to overcome it.I have tried creating a different database the same way to see if that help but it doesnt.
Is there something I might be missing in the creation of my SQL db that might be causing it?
i am building my first VB.net application with a connection to an Access database. Now, this works fine when I debug, however when I deploy the application I get the error saying "Could not find file", which I assume means i have got one of the publishing settings wrong? I don't think it is a code error because it works when I debug, but if anyone wants to see part of it please let me know.
