Adding info to OIP from PIO

[Cloud Hidden]

2-part question:

1. I'm creating a composite object in a PIO. I want to calc the area and perimeter and output it to the OIP in the same way that many other objects list area in the OIP. Don't know how to output that stuff.

2. Perim and Area require search criteria as parameters, rather than a handle. What's the typical strategy for creating something that can be uniquely searched. If I use the PIO multiple times, I don't want the Perim of the multiple occurrences...I want each one separately.

Thanks for any ideas.

1. Try

IF GetCustomObjectInfo(objectName, objectHand, recordHand, wallHand) THEN SetRField(objectHand, Getname(recordHand),'Area',Num2Str(1,A));

{'Area' is the paramenter name, A is a Real number}

2. Try

FUNCTION ??HArea (?h:HANDLE?) :REAL ;

Description:

Function HArea returns the area of the referenced object.

That is very cool. I'm indebted to you. Thanks. I kept looking for write-only fields, but no problem that these are read/write--it's not like the script has to read them. Works great.
