I am trying to import a text file to an access database in VB2008 express. The text file I am testing with is a csv file with 34,000 records. The problem is this takes 2 minutes to read through all this and write it to the database. The actual text file I will be using in production has over 800,000 records and this will take a ridiculous amount of time. I think I am doing something wrong. I have posted my code below. I am reading a record, parsing out the fields to an array, then creating an SQL statement to insert the record and executing it.
reader = New IO.StreamReader(fname)
Do While reader.Peek() >= 0
linesread = linesread + 1

View 2 RepliesI am writing a program for a class and it needs to read/write to an Access 2007 database. Right now I am referring to it's absolute path when I use it in connection strings, something like:
Dim conn As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:UsersMeDocumentsVisual StudioProjectsProject1Database.accdb")
This is going to be a problem when I turn it in obviously, because the professor isn't going to have the same path. So I want to somehow include it into my project and then refer to it with a relative path or something so that it will work on his machine. When I imported it through the Data Sources it had an option at the end to copy the database into the project which I agreed to. It put the Database where all of the source files are on my computer, so I tried using Application.StartupPath(
I have been reading some on .net and databases. I have a fairly large replicated database at work for call logging and I am going to be making a .net app to use for call logging. My question is, do I write a program that connects to the database pulling and pushing data or do I import the database into the .net application and then discard the database? Is it possible to import the database into a .net app? Which is the better idea if they both are possible?
I imagine if I write an app that connects to a database, then I could use a DB that is on our server so that it is like using a replicated DB. Everyones changes being made to the same database. Can multiple users use an app that is connecting to one DB? How can I preserve the replication functionality so that all changes are available to all users?

View 1 RepliesI have a machine which creates a new log file at the beginning of the day(12am) and updates the log file whenever there is any changes until the end of the day. How do I import the data in real time (30 sec, 1min or whenever there is any changes) to my SQL server database? Will SQL Server 2008 be able to access the active log file?
