Field Reference and Flowfield

trulyjacky

Hi,

I am using FieldRef.CLASS to decide the type of a certain field. But the compiler will complain something like FieldClass <>Option.....

For example:

IF "RecRef".CLASS = "RecRef".CLASS::Flowfield THEN
  "RecRef".CALCFIELD;

Is there any syntax error here? :?

Class is not option, it is CODE (or Text)

IF "RecRef".CLASS = 'FLOWFIELD' THEN
  "RecRef".CALCFIELD; 

or something else...

No, Kine, I cannot agree with you on this point. Look at the online help:

CLASS (FieldRef)
Use this function to return the fieldclass of the field that is currently selected. This function returns an error if no field is selected.

Class := FieldRef.CLASS

Class

Data type: option

The return vale. The fieldclass of the field.

FieldRef

Data type: fieldref

The fieldref that refers to the field that you are interested in.

Oh... sorry. I it was for FieldRef.Type... :oops:

It seems that it's bug (one yeart old, but answer is not accessible for me) - but there is workaround>

IF FORMAT("RecRef".CLASS) = 'FlowField' THEN
  "RecRef".CALCFIELD;

You are genius Kine. This is good workaround. Thanx a lot! :P

Maybe (just maybe) it's wise the do something like this:

IF UPPERCASE(FORMAT("RecRef".CLASS)) = 'FLOWFIELD' THEN 
  "RecRef".CALCFIELD;
