Nested Structure?

6 posts in this topic

#1 ·  Posted (edited)

Hi mates. it's me again.

I'm stuck trying with a nested structure, I can find the best way to do the structure, I Thought making a long byte structure and then Peek the byte that y need, but I thinks is not efficient.

I have this:

$pointer="here my pointer"
$str=DllStructCreate("long;word;byte[4];Ptr;long",$pointer)
$b1=DllStructCreate("byte",DllStructGetPtr($str,3))
$b2=DllStructCreate("byte",DllStructGetPtr($b1)+1)
$b3=DllStructCreate("byte",DllStructGetPtr($b2)+1)
$b4=DllStructCreate("byte",DllStructGetPtr($b3)+1)
;msgbox(0,"",DllStructGetData($b3,1))

My ask is: is there some best way to do it.

I mean something like this:

$pointer="here my poitner"
$STRB=DllStructCreate(DllStructCreate("byte;byte;byte;byte")
$stra=DllStructCreate("long;word;HELLO as $STRB;Ptr;long",$pointer)
;obviously this is wrong

:sweating:

any suggestions is wellcome.

Regards.

$Str = "here my pointer"
$iLen = StringLen($Str)

$tStr = DllStructCreate("char[" & $iLen & "]")

For $i = 1 To $iLen
DllStructSetData($tStr, 1, StringMid($Str, $i, 1), $i)
Next
$pStr = DllStructGetPtr($tStr)

MsgBox(64, "Ret", DllStructGetData($tStr, 1) )
MsgBox(64, "Ret", GetStringFromPtr($pStr) )

Func GetStringFromPtr($pStr)
$tStruct = DllStructCreate("char[" & 0xFF & "]",$pStr)
Return DllStructGetData($tStruct, 1)
EndFunc
I don't know much about Structs still this would get you go.

Regards :)

Thanks for the answer. the problem is I need that my structure is complete because it will be fill it using his base pointer.

the only way that I think is making a long structure like this.

$s=DllStructCreate("long;word;byte b1;byte b2;byte b3;Byte b4;Ptr;long",$pointer)

or

$pointer="my pointer"
$sstr=";byte b1;byte b2;byte b3;Byte b4;"
$s=DllStructCreate("long;word" & $sstr & "Ptr;long",$pointer)

at least that there was another efficiently way.

thank PhoenixXL but I want avoid any Loop to fill my structure.

just like this:

$pointer="my pointer"
$sstr=";byte b1;byte b2;byte b3;Byte b4;"
$s=DllStructCreate("long;word" & $sstr & "Ptr;long",$pointer)

so, is there a better way?
