VS 2008 Database From Access And Array
May 10, 2009
I've got a program I'm working on and I've been entering all the data manually but want to move it to a database.I've constructed the database and have it in the program but cannot get access to the individual cells so that I can use them in computing the results..I have a database named DFTL.mdb with a couple tables, including one query that I'm trying to get data from. The query has 10 records each with 5 unique numbers that attatch to the records.I've tried every way I can think of of pulling this data so I can use it in my program.

I'm already connected to the datasource in my program, and I already have the information in an one dimensional array. I want the array to be put into the first empty row of the database table, and obviously it will keep all the data and just keep appending to the database, I don't want anything in the database re-written.

I have a program that creates an array of part numbers. I also have a database that holds part numbers and all associated information I need for other calculations. How can I search an MSAccess database table against all of the part numbers in the array? The Array will never have more than 100 items in it, the table has over 7000 records to search from. I've posted my nonworking code hoping someone can point me in the tight direction.
Dim rs2 As New ADODB.Recordset
Dim Test1(7000) As String
Dim Test2(7000) As String

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]
