SizeOf( Array() ) ?

[The_CodeMaster]

Than i can't convert this Source from Powerbasic to Purebasic.

euhm, if you have an array in PowerBasic from ex. (30 to 90) then just convert it to (0 to 60) or just 'dim variable(60)'. You'll have to make sure that the starting-index is 0 and in this case you'll have to substract 30 to get THAT 0.

So it's possible to convert, but proberly a lot of work .

Tried to read your german post, but don't understand German.

Thanks for your tip. I will see to convert the Powerbasic Code to Purebasic.
I hope this do funtionary in Purebasic to write an XLS-Sheet.

Sorry, but i can't translate all german Thread with my little english.

Best regards from germany

Code: Select all

Procedure.l ArrayMemorySize(*Array)
  !sub [esp], dword 8
  !push dword [esp]
  !push dword 0
  !push dword [PB_MemoryBase]
  !call _HeapSize@12
  ProcedureReturn
  HeapSize_(0, 0, 0) ; make sure, _HeapSize@12 is defined
EndProcedure

Procedure ArraySize(*Array)
  ProcedureReturn PeekL(*Array-8)
EndProcedure


Dim Array.l(50)


Debug ArrayMemorySize(@Array())
Debug ArraySize(@Array())

ArrayMemorySize() shows the real size in memory.
ArraySize() shows the total number of elements.

Hey guys, have you seen that?
That's the Power of PureBasic

Code: Select all

Procedure.l ArrayMemorySize(*Array) 
  !sub [p.p_Array], dword 8 
  !push dword [p.p_Array] 
  !push dword 0 
  !push dword [PB_MemoryBase] 
  !call _HeapSize@12 
  ProcedureReturn 
  HeapSize_(0, 0, 0) ; make sure, _HeapSize@12 is defined 
EndProcedure 

Procedure ArraySize(*Array) 
  ProcedureReturn PeekL(*Array-8) 
EndProcedure 


Dim Array.l(50) 
array(8)=45

Debug ArrayMemorySize(@Array()) 
Debug ArraySize(@Array())

ArrayMemorySize() doesn't work in PB 4.02

And 2nd: what about SizeOf(linkedlist())

[Mistrel]

This code gives me the size of the array +1. Is it safe to assume that in PB4 the correct value is PeekL(*Array-8)-1?

Code: Select all

Procedure ArraySize(*Array)
  ProcedureReturn PeekL(*Array-8)
EndProcedure

Dim Array.l(50)

Debug ArraySize(@Array())

There is no problem:

Dim x(3)

=

x(0) 1 element
x(1) 2 elements
x(2) 3 elements
x(3) 4 elements

In an array dimed like that "Dim x(50)", there's fifty one elements

[Kaeru Gaman]

in other words, it does not give you the size of the array +1,
but precisely the size of the Array.

remember, in PB you Dim an Array withe the index of the last element,
not with the numer of elements, and an array always starts at index 0.

so, with Dim x(50) you Dim 51 elements as Olli said.

if you want 50 Elements, you'll need index 0-49, then use Dim x(49)

...this is different to other BASIC languages, but it's a known issue in PB.

Updated

Code: Select all

Procedure.l ArrayMemorySize(*Array) 
  !sub [p.p_Array], dword 20
  !push dword [p.p_Array] 
  !push dword 0 
  !push dword [PB_MemoryBase] 
  !call _HeapSize@12 
  ProcedureReturn 
  HeapSize_(0, 0, 0) ; make sure, _HeapSize@12 is defined 
EndProcedure
