Label that can read objects

Anonymous — Sat, 21 Aug 2010 03:22:57 GMT

I'm working on a label that will note the selected parameters of an object. I have figured out how to get the value of a parameter if I know the parameter in advance.

Is there a way to read the parameters in any object? ...perhaps a request function I'm missing.

The goal is to select an object, label it and choose the parameter to label from a menu (driven by the parameter script).

Best, Patrick

Try this one:
ASSOCLP_NAME

Yes. I have used ASSOCLP_NAME to get the name of an object and ASSOCLP_PARVALUE to get the value of a particular parameter.

The problem is that I need to know the parameter I'm looking for in advance. In other words if I want to label a seat with the material it's made out of, I would need to know that the material parameter is SEAT_MAT. I would love to be able to attach the label to any object and see what parameters are in the object.

Have a look at this code:

! Etikett-Parameter-Routine von Frank-Beister+ Jochen Sühlo


DIM NP[],valS[],valN[],valA[],valAt[],askP[13],valP[],sts[],stsT[]


!### request all parameters from main object and
!### store name and value into the arrays

i=1

do
  NameP=""
  rrr=REQUEST ("ASSOCLP_PARVALUE", i, NameP, Art, Zustand, Dimension_1, Dimension_2, Wert)
  if rrr then
    NP=NameP : valS="" : valN=0 : valA=Art

    if Art=4 then valS=Wert else valN=Wert
	endif

  while i<501 and rrr

  for i=1 to maxP

    ADD2 0,s

    NEXT i

Thanks so much. Can't wait to try this. I would have never figured this out.

Many thanks to Frank-Beister+ Jochen Sühlo for their code,

I had a chance to play with this today. I must say this bit of code is great! I learned a lot of things I would have never discovered from the GDL manual. Now I'm working on sorting out the unnecessary parameters to create a useful label object.

What could you learn, if you could read selfGDL.com. 😉

selfGDL.com just made it onto my bookmarks bar. I love the way your site is organized. Now I just have to learn German.
