I am using VB2005. I am trying to write to an Access database seperate from the data's origin. AKA: I need to run a query getting data from one Access table and write it to a table in another Access database.
Overview: I need to get data from one Access table and two Excel worksheets. I need to write the data to an Access database so I can run a query combining the three into one table. I will then use the table to create reports.
I have googled, checked multiple sites, and checked MSDN. The only thing I have been able to find is populating a datatable and writing changes back to the database. This was SO easy in VB6.
Is it possible to write to an access database that is an MDE, from a .net application?

I want to use VB2005 to export tblCustomer from One.mdb to Two.mdb, and replace the existing tblCustomer in Two.mdb, during run time. I basically want to simulate the export function that is available in MS Access (which can export one table from one Access database to another) with VB2005 during run time. I can think of a way by querying the table to a dataset and then delete everything on the other database before filling the table in that database with the dataset

I'm using VS 2010, and I did a project using VB and a database in Access. The problem is that when I try to put that "application" on other computers, sometimes, is not working. I thought it can be because on these computers they don't have access, but on one computer, is running another app which is using Access and there is no Access installed. How can I check if my application requires Access to be installed or not?
Here is a example of how I did the connection:
Public AccessOLEDBConnString= "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & myfullpath & ";Jet OLEDB:Database Password=password"
Function getConnection() As OleDb.OleDbConnection
[CODE]...
And when I want to have access at the data I'm doing like this:
dim conn as Oledb.OledbConnection
dim sql as string
dim ds as Dataset
[CODE]...
I've looked for code on this, and it seems needlessly confusing to me. I've tried some code I found and it doesn't return the proper value (I can't find the link to it now). So, I'm attempting to avoid that which I do not understand by writing a function that creates then deletes a file:
Friend Function GetFolderAccess(ByVal sDirectory As String) As Boolean
Try
Dim fs As New FileStream(sDirectory & " estfile.test", FileMode.OpenOrCreate, FileAccess.ReadWrite)
Dim s As New StreamWriter(fs)
[code]....
Through testing, this appears to work for both read and write access. I originally had a File.Exists before the File.Delete, but the function would sometimes return True when it should have returned False.
