• Add some Hint info
• X64 Version uses includes files form OPC Core Component 3.0.106.
  • Install OPC Core Component is NECESSARY, I bundled the 3.0.105.1 version (seems more popular).
• Tested with MatrikonOPC Simulation Server
  • You can get it free at offical site after reg.
  • Start OPC Simulation Server, then build project.Run the demo, input hostname, then input server ID, it should work.
• I advice you to use hostname instead of IP address for reasons below.
  • If you want to access OPC by IP, you have to enable RemoteRegistry service in services.msc
  • Also , for UAC problem after Vista, your program must run as admin to avoid some issue.
