Adding Request to script

Anonymous — Fri, 07 Jul 2006 02:51:04 GMT

I am trying to add a request string to a library part. I have the correct request:

n=REQUEST ("Zone_relations", "", category_name, code, name, number ,category_name2,
code2, name2, number2)

TEXT2 0, 0, number

but do not know the code to make it a string/parameter within the part.

New to GDL and hope someone can help??

Fred,

try to put this in the parameter script

n=REQUEST ("Zone_relations", "", category_name, code, name, number ,category_name2, code2, name2, number2)

PARAMETERS name=name

I am assuming that you have created the parameter 'name' in the parameter list...

Robert,

Thanks for your reply.

Yes I have tried this:

Master script:
n=REQUEST ("Zone_relations", "", category_name, code, name, number ,category_name2,
code2, name2, number2)

Parameter Sript:
PARAMETERS number=number

PARAMETERS name=name

Parameters:
Variables name + number (type - ABC)

No joy - I am trying to extract a room number from a zone that the
object is placed in for room data sheets.

Have I got the sequence wrong?

This is again the problem that some REQUESTs do not return a valid value in the moment PARAMETERS works proper. Other way round PARAMETERS does not any affect to the denoted parameter, when the REQUEST offers the searched values.

One of these cases is the zone-relation request. Sorry. No hope to transfer the result to a parameter by parameters. Use in 2D-script, but not in parameter script.

You are the third (I know from) in the last half year, who tried this. No chance IMHO.

Fourth. Very frustrating.

Thank you all. Will revise my approach to this problem. Thanks for stopping me go down the wrong road.

Wouldn't it work to use:

PARAMETERS MY_room_number = number

Where "MY_room_number" is a named parameter in the list?

No, it wouldn't, because number is "" in any moment PARAMETERS works.

You are right, to write

if not(number="") then PARAMETERS number=number

would be better, but this does not work too. See above.

I just tried putting the whole bit into the master script to see if the execution order would be different. Strangely the part works outside of a zone, but once moved inside the symbol vanishes leaving only the big dot. This is despite having a Rect2 in there to make sure it wasn't just the text disappearing.

I should have known, that you would try. 😉 Maybe the request changes the variable from string to numeric. wrap a if vartype(number)=2 then ... around it.

See the following threads:

http://archicad-talk.graphisoft.com/viewtopic.php?t=10858&postdays=0&postorder=asc&highlight=write+file&&start=0

The last one shows how to write out the values into a text file to see the context, script type and value in each running.

That is exactly what happens. Normally when window or door is placed to wall between two zones, the values the REQUEST ("Zone_relations" ...) returns are strings. But when there is no zone it returns 0 which is a number. So if you make IF-statement to that value, each time when the value isn't proper it "crashes" (only the black dot appears)
So first I must be sure that the value is proper type.

This request function really sucks btw...
