Hey there, I can help you in developing this class for the given features. I will need some more information like: What user authentication process will it follow? Like AD? or from database? What data needs to be transferred between Server/Client? XML? Database? JSON? Serial? Lets discuss the specifics of this project via chat. Thanks, Muhammad

Hey, I saw you new project. I wanted to clarify a few things. I do not understand the reason for creating a server-side service that listens to requests, fetches data and transfers back. Usually in this type of application, the client connects to the remote data that holds all user privileges and returns results on query. This also ensures data integrity and that user rights are never violated. Same goes for File transfers. The standard is to have an FTP server running with several used with access privileges. The client then access the files remotely. If it is about the security, let me ensure you that a filezilla or Godaddy FTP server or a MS SQL Server, when properly configured, is much more secured than a VB.NET code anyone on this site will make.
