Hi

Is it possible to run Operating System Command and get the result using coffee?

If not, how can i handle releasing demo plugin and key to full version?

This would be very unsafe.
Someone would just need to replace the executable with one that does always end with the result needed for activation.

The best way to protect COFFEE Plugins IMHO is to use an algorithm that is unknown to others which determines if a License Key fits to a specific Cinema 4D Key.
See this example:

createLicense() {  
  var c4dLicense  = SysGetUserInfo(0);  
      c4dLicense  = evaluate(strmid(ser,6,5));  
        
  var licenses    = new (array, 3);  
      licenses[0] = int(Modulo(ser*(pow(ser/1242,3)),979975));  
      licenses[1] = int(Modulo(ser*(pow(ser/8951,3)),457382));  
  // ...  
  return licenses;  
}

Which might evaluate to a serial like this: 8616 - 121 - 8913

Use this function to create the license, and also to check it.

var userL       = getLicenseEnteredByUser();  
var correctL    = createLicense();  
var i           = 0;  
for(i = 0; i < sizeof(licenses);  i++) {  
  if (userL[0] != correctL) {  
      // license is wrong !  
  }  
}

Cheers,
Niklas

Using COFFEE I can execute program or open file, if success return true.

Is there a way to execute a program and pass command parameter and get the output result?
