Hi,

In this example I used a option group with 6 Boxes (property Number of Boxes =6 ).

The property Selected Box é dynamics by change of tag "prioridade_temp".
See the C script to dynamics this property:
///////////////////////////////////////////////////////////////
long _main(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName)
{
SHORTsValor=0;
LONGlRetorno=0;

sValor=GetTagSWord("prioridade_temp");

switch(sValor){
case 1:
lRetorno=1;
break;
case 2:
lRetorno=2;
break;
case 3:
lRetorno=4;
break;
case 4:
lRetorno=8;
break;
case 5:
lRetorno=16;
break;
case 6:
lRetorno=32;
break;
default:
lRetorno=0;
break;
}

return lRetorno;
}
///////////////////////////////////////////////////////////////

If you need capture the selection of operator, you can use this code in event "Selected Box Change"
///////////////////////////////////////////////////////////////
void OnPropertyChanged(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName, long value)
{

SHORTsValor=0;

switch(value){
case 1:
sValor=1;
break;
case 2:
sValor=2;
break;
case 4:
sValor=3;
break;
case 8:
sValor=4;
break;
case 16:
sValor=5;
break;
case 32:
sValor=6;
break;
default:
sValor=0;
break;
}

SetTagSWord("prioridade_temp", sValor);

}

You are welcome.
