C++ DLL Alteration / Modification

Project Description: Modify Existing DLL in C++ to add additional functionality Language: C++ (Managed) Background Information: The attached DLL connects to the local default instance of SQL Server and Backs up the database using the Virtual Device Interface. This allows me to use this DLL in C#, and backup to Managed Streams, compressed or encrypted. I need some changes to alter the constructor to accept username/password and for the Backup event to be multithreaded. ## Deliverables Example: using VdiDotNet; VdiEngine BackupDevice = new VdiEngine(); [login to view URL]("BACKUP DATABASE " + DatabaseName + " TO VIRTUAL_DEVICE='{0}' WITH STATS = 1", CompressedBackupStream); Changes Required: 1. Make this DLL accept parameters so that it can connect to remote servers - username - password - servername - integrated I would like the constructor overloaded as follows: - For a local server, trusted link: VdiEngine(); - For a remote server, trusted link: VdiEngine(string sServerName); - For a remote server, specify login and password: VdiEngine(string sServerName, string sUserName, string sPassword); 2. Add Support for multiple devices. device count is set with [[login to view URL] = 1;] I need this to be able to return a variable number of streams to C# using multiple threads for speed. I also need an example in C# of how to use these streams with multiple threads. In C# I would like to be able to call a function like this: BackupDatabase("northwind", "C:\[login to view URL]", 3) The result of whcih would back up the northwind database over 3 files called: [login to view URL] [login to view URL] [login to view URL]
