Description
Evaluates whether an object meets the specified search criteria.
When used with record criteria, it will determine whether a specific record is attached to the object; if used with record-field criteria, it will return the value of the field as a STRING.
FUNCTION EvalStr(
h :HANDLE;
c :CRITERIA) : STRING;
def vs.EvalStr(h, c):
return STRING
Parameters
h HANDLE Handle of object to which the search criteria will be applied. c CRITERIA Search criteria.
Return Value
If the criteria is a record-field criteria, the procedure will return the value contained within the field. All other criteria return the TRUE-FALSE state of the criteria condition.
Remarks
_c_, 2015.06.17:
Don't forget the brakets or it will block the rest of the script in a totally unpredictable way upon any special char. I suppose that it tries to parse the rest of the script as criteria:
crit := '.'; { suspiciously dangerous special char }
str := EvalStr(gTargetH, crit); { strange failure of parts of the script after this call ! }
str := EvalStr(gTargetH, (crit)); { correct }
Example
VectorScript
dataValue:= EvalStr(handleToObject,('Part Info'.'Serial No.'));
