Look in the commented asm, you need to import them before using (just reference HeapCreate_() somewhere in your PB code and it will be the same).

You are right, this working as in pure FASM:

!if ~ defined _HeapAlloc@12
!extrn _HeapAlloc@12
!end if

!if ~ defined _HeapReAlloc@14
!extrn ...

Why is it useful to allocate a 0 bytes memory area ?

Functions the AllocateMemory and ReAllocateMemory in windose PureBasic versions should not be a procedure, it must be a macro to create the calls to HeapAlloc and HeapReAlloc.

Compiled application should not be used initially artificially ...

Look in the commented asm, you need to import them before using (just reference HeapCreate_() somewhere in your PB code and it will be the same).

I have a few questions.

1. For what in the PureBasic is specially refused the HeapAlloc and HeapReAlloc with zero size?
Possibility to create zero ...

I can use calling:
!PUSH dword [_PB_MemoryBase]
!CALL _HeapDestroy@4

I can use calling:
!PUSH dword 0
!PUSH dword 4096
!PUSH dword 8
!CALL _HeapCreate@12
!MOV [PB_MemoryBase], EAX

But can't calling:
!CALL _HeapAlloc@12
&
!CALL _HeapReAlloc@16

Error: undefined symbol

How to call ...

I propose to extend the operators by optional parameter Mode :

Position = FindString(String$, StringToFind$, StartPosition)
up to
Position = FindString(String$, StringToFind$, StartPosition [,Mode])

and

Result = CountString(String$, StringToCount$)
up to
Result = CountString(String ...

Code: Select all

*mem = AllocateMemory(100)
PokeL(*mem + $0000, $12345678)

*mem = ReAllocateMemory(*mem, 200)
Debug StrU(MemorySize(*mem))
Debug PeekL(*mem + $0000) 

May be into the PureBasic exist constant the Heap ID of task, like #PB_HEAP ?

Are you planning to do change static lib ..\PureBasic\PureLibraries\Windows\Libraries\zlib.lib
from version 1.2.3 to the newest version 1.2.5 ?

Suggest to description into the http://www.zlib.net/ , the version 1.2.3 is have a lot big bugs:

Version 1.2.4 has many changes over 1.2.3, including ...

If exist the MoreListIconGadget UserLib for the PureBasic 4.5x/4.6x then also can help (for free).

How to make ListIconGadget with the more that one CheckBox in Row?
On Windows that would be very difficult using the Microsoft ListView control (which is
the underlying basis of the ListIconGadget) even if using API functions. But RASHAD
has found a kind of "cheat" by using two ListIconGadgets ...

There may be an easier way to do this, but this will start you off with icons in other columns.

How to make ListIconGadget with the more that one CheckBox in Row?

Like this:

These procedures are taken from the "wincap32" DIB API.
They deal with creating, loading and saving windows bitmaps.
You can get the original source code here:

Edit: I have removed the BITMAP parameter in CreateDIB, LoadDIB and LoadBMP and ...

It would be nice to expand the directive "Data" by
"Dup" operator then make multiple copies of values (like in FASM).

Like this:
Data.B 4 Dup (5) = Data.B 5,5,5,5
Data.L 8 Dup (1,2) = Data.B 1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2

Okay.
8-bits unsigned as .A
16-bits unsigned as .U

What about 32-bits UNSIGNED values?

What wrong in this code?

Global BPB_Media.B = $F8

Select BPB_Media.B
Case $F0,$F8 To $FF
Debug "BPB_Media: $"+RSet(Hex(BPB_Media, #PB_Byte),2,"0")
Default
Debug "Wrong BPB_Media: $"+RSet(Hex(BPB_Media, #PB_Byte),2,"0")
EndSelect


In fact, with such value
BPB_Media.B = $F8
