Data send-receive over internet

I want a simple stand-alone software (without GUI), that can send and receive text data containing any characters from 32 to 255 ASCII code to another computer from internet that have the same stand-alone software running. The software will use registry as input/output in the following way: ## Deliverables I want a simple **stand-alone** software (**without GUI**), that can send and receive text data containing any characters from 32 to 255 ASCII code to another computer from internet that have the same stand-alone software running. **The software will use registry as input/output in the following way:** The software must have a fixed registry working path with with these name values: 1. HKEY_LOCAL_MACHINE\SOFTWARE\Radcs\**command** 2. HKEY_LOCAL_MACHINE\SOFTWARE\Radcs\**ip ** 2. HKEY_LOCAL_MACHINE\SOFTWARE\Radcs\**receiveddata** 3. HKEY_LOCAL_MACHINE\SOFTWARE\Radcs\**senddata** 4. HKEY_LOCAL_MACHINE\SOFTWARE\Radcs\**status** **The program will monitor the "command" value from registry.** When "command" value is different from "" (blank space or 0), will execute the specified command. **Then will send a "" blank space value to "command" and wait for a new command.** **The time between sending a text data to another ip, and waiting for a new command must be at most 1 second. Faster-Better**! Where "command" can have one of these values: 1. **start ** (will start the server, optionally, if required) 2. **status** (After any executed command will be an status report: in HKEY_LOCAL_MACHINE\SOFTWARE\Radcs\status) Returned **status** message will be: "started" if local server is started, else "stopped" "connected" if the 2 computers are connected and can communicate, else "disconnected" "online" if check command result is true, else "offline" 3. **connect** (will connect to the ip shown in HKEY_LOCAL_MACHINE\SOFTWARE\Radcs\ ip ) 4. **disconnect** (will disconnect from current specified ip, and ready to connect to another ip) 5. **listen** (will listen and wait for data to be received from that ip) 6. **send** (will send data to that ip , while do NOT stop listen) 7. **check** (will check if specified ip exists or is offline) 8. **exit** (will exit (terminate) the program) **Any received data will be saved in HKEY_LOCAL_MACHINE\SOFTWARE\Radcs\receiveddata ** The software must be stand-alone, with no GUI, and without dependencies. I want the software to use **TCP protocol**, **NOT udp**. The data length that can be sent once, must not be less than 255 characters Will work on Windows 2000,XP,Vista,Windows7 Will use possible **small cpu** & memory load **Will NOT crash**. Preferable in C/C++ language or any other that will work without needing of additional programs to be installed. Will work on the internet, i am not interested in LAN functionality. I want the compilled version, with a simple square as icon, the source code and full documentation with final commands names. The source code will include some notes to be able to change working registry path. ____________________________________________________________________ **Guys, given the fact that [login to view URL] do not accept users that do not have verified Paypal account (my Visa card is not accepted in Paypal), i have to close this project and find coders elsewhere on the web. :( **
