Question

My loggining form is stopping on connection.Open(); , I'm getting an error: System.Data.OleDb.OleDbException: unrecognized database format . Code with connection operations:

    OleDbConnection connection = new OleDbConnection();
    connection.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=W:\Data Base\Test.accdb;
Persist Security Info=False;";
    connection.Open();
    connection.Close();

What to do with that? Thank you very mutch for your help.

I don't think you need the @ before your string. Also I think you should do like this :

connection.ConnectionString = "Server=[server_name];Database=[database_name];Trusted_Connection=true";
