#2267 closed Feature Request (Rejected)

Eval Flag (new Feature Request)

Reported by: DXRW4E Owned by:
Milestone: Component: AutoIt
Version: Severity: None
Keywords: Cc:


At present Eval() Returns the value of the variable, and possible to add a flag, so as to return the pointer of the variable, pointer to be used in autoit fuction with the ByRef

Eval() works really fast, in a test with a 200 MB array, works in about 0.040 seconds, so the speed is not the problem, but the memory in use

;example $XArray[1000000] size 100 MB
Assign("$Array", $XArray, 2)
;;Once you have created the $Array, suppose that $XArray = ""

Global $a = Eval("Array")
Test($s) ;I have to take by force the $a, so that after use with ByRef, so in this case it uses 200 MB of memory

Func Test(ByRef $c)
ect ect

;it would be really nice to do so
Global $b = Eval("Array", 1) ;only return the pointer of $Array, pointer that is Ok with the ByRef mod

Func Test(ByRef $a)
ect ect

Sorry for my English

Your English is not a problem.

No to the request. Function like Eval should be used only in extreme cases when there is no other way to access data (e.g. unknown number of function arguments). Extending its functionality would eventually lead to the abuse of usage.

I understand

Thank You

however to clarify the situation, what I was trying to do and an INF edit fuction, as well as Microsoft ago, the best way and create a handle, so as to be faster when reading or modification of the file

so I chose to do so, to imitate the handle in autoit , load inf file (so I can open many inf append ect ect), the fuction return inf handle, handle number (to be added at the end of the "INFNAMEXXX" variable name, to take the array with Eval) where and loaded the INF file

; $DX_HINF[0][0]
; $DX_HINF[1][0] = INF Handle
; $DX_HINF[1][1] = INF Path
; $DX_HINF[1][2] = INF Handle where this INF File has been Appended
; $DX_HINF[1][3] = INF Handle Appended
; $DX_HINF[1][4] = INF Variable Name
; $DX_HINF[1][5] = INF Handle of Default Strings Section
; $DX_HINF[1][6] = Last NOT Default INF Handle Strings Section

; $DX_SetupOpenInfFile[5] = Inf Local Strings Section Name

ect ect ect



so basic idea ninth work with pointer in autoit, but imitate a handle in autoit, however and all Ok (I understood what you meant above). this was just to clarify the situation or or what I wanted to do with EVAL

Eval() is a function which leads AutoIt software to be considerd as a malware.
I am afraid this request will extend it more ...
