How can I return structure from other DLL made in C++?
example:

Structure 
   a.l
   b.l
   c.l
   d.l
EndStructure


OpenLIbrary(0,"etc.dll")

Number CallFunction(0,"myfunc",33,44,77,11)

and to return data in my structure?
[/code]

Hi
I can tell you how to receive an element of a STRUCTURE from a (normal) procedure or libraray (i believe) itÂ´s the same like from a c++ Method:

You need the STRUCTURE of the STRUCTRE o_O ...
Without the information about the STRUCTURE you will get back it isnÂ´t possible to do it.

Code: Select all

STRUCTURE johnstructure
  a.l
  b.l
  c.l
ENDSTRUCTURE

You will receive a pointer to the element this way: (You ALSO have to tell PB the STRUCTURE of it)
This way:
It means PB creates a NEW element when you have called the procedure/method/whatever

Code: Select all

*myelement.johnstructure=CallFunction(foo)

If you try to modify the content of this element:

Code: Select all

*myelement\a=1
*myelement\b=1

Or if you want to read it:

Code: Select all

debug *myelement\c

You also can give THIS element to a further procedure/library/whatever:

Code: Select all

myprocedure(*myelement)

Please also note: to call a procedure/method/whatever with A NEW element works this way:

Code: Select all

newelement.johnstructure
MySuperFunction (@newelement)

I hope this is what you need.

PS: If you know how to call a c++ Method successfully let me know !!
