     Simplifies the use of the winsock control in creating a client/server connection of TCP/UDP IP network. The winsock control was extremely clumsy when you need to make multiple connection (EX: server application) you were limited in the number of connection you could have because VB's control array limitation (approx. 32000). When a connection was lost, you needed to sort through the array, remove the 'dead' control and re-index the array. Also there was a bug in the earlier versions of the winsock control where only the last control added to the array could send data. What I have done was created an activeX .dll that you could reference in your project that mimicks the winsock control. Instead of using an array of controls, every connection is added to a collection (collection manipulation is much better and easier than an array). Plus I have added serveral useful server functions, such as .BroadcastAll (send data to all connections), .KillSocketOnClose (removes connections from the collection automatically when the connection is lost), .CreateServer (creates the server with one line of code), ect. PLEASE NOTE: When compiling this project, make sure that the Winsock control is referenced. This code still uses it for all the dirty work.

Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com
