I've recently made another question about connecting to MS-ACCESS database with .NET in C# or VB.NET. It worked just as intended with MDB, but with accdb it caused an exception in
conn.Open();which follows:
Is there another way to do this? My original intention (like stated in the original question) is gathering some (actually, a lot of) fields.
Previously i used Visual Studio 6 Professional Ed. Now on to 2010 Ultimate.I just want to know how to connect a .accdb (Access 2007 database) in VB 2010 and retrieve/edit/delete records....?
In VB 6.0. i used the code as below to open a .mdb database file....
xyz.mdb contains a table called "pwd" with fields "User" & "pwd"
Public db As Database Public rspwd As Recordset
Set db = OpenDatabase("xyz.mdb", False, False, ";pwd=abc") 'To Open Database
Set rspwd = db.OpenRecordset("select * from pwd", dbOpenDynaset) 'To Open a table as a recordset
i have a database and it file format is accdb. can i make it as another file format and the only one can read it is my system?if yes it is possible(maybe impossible for me because of lack of knowledge)
View 3 Repliesi want to connect to a .accdb access database. the connection string is:
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:myFoldermyAccess2010file.accdb;Persist Security Info=False;
so if i want to make sure this works on any computer, should i just add the reference to:
Microsoft Office 14.0 Access Database Engine Object Library
is this all i need to do?
Does any of you know of a way to create an Ms Access Database (either mdb or accdb) without having to use adox or interop?

View 2 RepliesA. A Visual Basic program is developed to read a text file to Access 2003 database using the Data Access Objects (DAO). The following is the DAO command:
Set db = DAO.DBEngine(0).OpenDatabase("C:TempMyAccess2003.mdb")
B. The office Access 2003 database (*.mdb) is going to be upgraded to Access 2007 database (*.accdb).
C. The Visual Basic program is revised to read the same text file to Access 2007 database using the same Data Access Objects (DAO), The following is the DAO command:
Set db = DAO.DBEngine(0).OpenDatabase("C:TempMyAccess2007.accdb")
D. The following error message occurs when the revised Visual Basic program is executed:
"Run-time error '3343': Unrecognized database format"

Question: How do I programmatically determine which provider to use (Microsoft.Jet.OLEDB.4.0 vs Microsoft.ACE.OLEDB.12.0) when my app runs as a 32-bit process on a machine with Office x64 installed?
I'm developing a VB.net WinForms app in VS 2010 and targeting both x86 and x64.The app processes data from xls, xlsx, mdb and accdb files using System.Data.OleDb:Dim oConn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=...")
The x64 version of the program works as expected. The x86 version works as expected on a system with Office x86.When I run the x86 version on a machine with Office 2010 x64, I get the following exception when trying to open a connection:
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.I believe this is because I'm running Office 2010 x64 so the x86 data access components are not installed.I can get it to work for Office 2003 files (*.mdb and *.xls) by changing the provider to Microsoft.Jet.OLEDB.4.0.
How do I figure out which provider to use when running as a 32-bit process on a machine with Office x64 installed?Ideally, I'd like a function:If ProviderIsAvailableFor("Microsoft.ACE.OLEDB.12.0") Then
Else If ProviderIsAvailableFor("Microsoft.JET.OLEDB.4.0") Then
I'm using a OleDB connection to a access database. I'm entering a row into the database to set some user preferences. What i need to get is get back the row ID of the row I just entered. I'm more familiar with PHP and with PHP I use use this entry

View 3 RepliesI 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.
View 4 Repliesjust 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?
