Can't create textblock with string from REQUEST(...

Anonymous — Wed, 16 Nov 2016 18:39:55 GMT

Hello!

My code:

REQUEST ("Zone_category", "", catname, code)
TEXTBLOCK "MY_TEXTBLOCK_1" 0, 5, 0, 1, 1, 0, catname

I get the error "requires an expression of type string"

But:

catname = "tmp_cat_name"
TEXTBLOCK "MY_TEXTBLOCK_1" 0, 5, 0, 1, 1, 0, catname

work without errors.

How I can get category name and create textblock with it?

Help me, please!)

Maybe this is a bug in ArchiCAD. I dont't know.
But this works, if you want to use TEXT2:
x = REQUEST ("Zone_category", "", catname, code)
TEXT2 0, 0, catname

Maybe at first before request:

catname = ""

guessing...had something similar lately.

Best Regards,
Piotr

TEXTBLOCK "MY_TEXTBLOCK_1" 0, 5, 0, 1, 1, 0, catname

It should work normally.
I do not think that you accidentally forgot about the paragraph, but here is the complete code (simplified, without coefficients) just in case.

Catname = ""
Catcode = ""
	QW= REQUEST("Zone_Category", "", Catname, Catcode)
PARAGRAPH "NAMECAT" 2, 0, 0, 0, 1
	""+Catname
	ENDPARAGRAPH

TEXTBLOCK "CAT" 0, 5, 0, 1, 1,1,"NAMECAT"
RICHTEXT2  0, 1, "CAT"

I find with REQUEST you always have to say xxx = REQUEST...
This is because it returns a value to xxx if the request is successful or not.
As well as returning the actual values you were requesting in the first place.

Its work!

Catname = ""
Catcode = ""
QW= REQUEST("Zone_Category", "", Catname, Catcode)
PARAGRAPH "NAMECAT" 2, 0, 0, 0, 1
""+Catname
ENDPARAGRAPH

TEXTBLOCK "CAT" 0, 5, 0, 1, 1,1,"NAMECAT"
RICHTEXT2 0, 1, "CAT"

SL_GDL, many thanks for the help!

to avoid errors with str var type after REQUEST it is better to do so:

QW= REQUEST("Zone_Category", "", Catname, Catcode)

IF QW <> 0 THEN ! if answeres more then 0
Catname_ = Catname
ELSE
Catname_ = ""
ENDIF

PARAGRAPH "NAMECAT" 2, 0, 0, 0, 1
Catname_
ENDPARAGRAPH

TEXTBLOCK "CAT" 0, 5, 0, 1, 1,1,"NAMECAT"
RICHTEXT2 0, 1, "CAT"
