I have an accdb named base.accdb in the root folder of the program. Basically I have several tables in my database and I need to show their values in listboxes (essentially allowing menus to be edited by adding/removing items in the table)I can't figure out how to connect the database (according to my friends/classmates), and i can't figure out how to pull the information from the table.
Ultimately, it would be nice if someone could tell me how I can pull out the information into maybe an array? so that if i add 3 items into the table, then it will create 3 variables in the program and put the values from the table into those variables.

I have created a program to log company and programming information for a radio station, on the test machine it works perfectly when deployed the program cannot read from the database. It creates it fine and can write to it without complaint but when opening the program which is supposed to read information from the database the program crashes, if i ask it to continue then it will bring up the form but nothing which is supposed to be populated by access to the database is populated.ed onto the deployment machine and this does not solve the problem.
this is code relating to the issue:frmMain:

I'm currently attempting to save data inputed into a data grid clicking the "save" button. My problem is, I also have another DB opened in the same window that also needs to be saved. The second database is pulled up by the contents of a text box, so there for it has no real Dataset to call on. It looks something like this.

I try to run the update command it always throws the exception "Cannot find table 0" or "Update unable to find TableMapping['Table'] or DataTable 'Table'." I tried declaring the connection the same way as the code above and then simply calling the da.update(ds) but it wouldn't do anything.

tell what 'visual' designer was used when developing an existing a VB.net 2008 desktop application? What do I click on to tell what 'visual' designer was used? Also once I know what visual designer was used, can you point me to a url to tell me how to use that visual designer? need to change some of the tables behind an existing desktop application. Basically some of the production tables will be changing. The users want to keep the existing desktop (gui) interface since they like it alot.

I am using MS Access 2007 as database and VB 2008 to build an application to show the content of 2 tables as a single table.I have two tables in MS Access and i have linked both the tables using "ID" as primary key(1st Table),foreign key(2nd Table). I used Query Wizard to show the data of both tables in a single table(3rd Table).I am able to view the content of all 3 tables using datagridview in vb 2008(Using Code), but i am unable to add,delete,save and search the content of the table using code. My concern is,i will be able to do all these operations using codes only.Would you please help me out in this.

I added a new database using SQL Server Management studio express 2008. I can connect to that database using Web Developer and Visual Studio just fine. But when I try to connect from VB Express 2008 I get an error message "file in use by another program". VB only prompts me for the name of the database, but Web Developer and Visual Studio prompts me for both server instance and database name. I'm sure this is just something simple I'm missing.

My problem does not seem to be the same as in other links. I'm trying to teach myself VB 2008 and I want to connect to an Access MDB file. I follow the instructions in all the different books and websites. I start a new project, choose a new data connection, change the type to Microsoft Access and browse for the file. When I get the connection string I press "Test Connection" and it's okay. I then drag either the entire table or just a field to the form. I use Data Preview Data and can see all the rows and columns and the data, so I know the connection has been made. however, when I press F5 I get a form, but no data and it says "0 records of 0".
I accessed the code and put a MsgBox before and after the "Fill" statement. The one before pops up, but the second one (below Fill) does not. I also get "A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll" in the Immediate Window. I have tried putting a "Try" statement around the code and in this case it will go to the second MsgBox, but still no data.
I'm following what seems to be the most basic and simple method, but I cannot get data in my form.

I would like to know how could i connect my Visual Basic program to a database that can be opened to MS Access. My friend made a program that links to a database that opens in MS Access and when you open the database the inputted data are organized to their respective columns and rows. However he used VB6 in making the program and he wont let me see the syntax. And another thing, the program that he made updates the database everytime a new set of data is inputted.

Currently I have this "commands" to access to a database in my computer:
Public conn As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source= " & System.AppDomain.CurrentDomain.BaseDirectory & "bd2.mdb;Persist Security Info=False;")
Dim strSQL As String = SQLcommand
Public cmd As New OleDbCommand(strSQL, conn)
My question is: Is there a way to connect to that database online?
Example: bd2.mdb is on [URL]
