CopyMemory API copy to another variable?

[Danyfirex]

Well mate today I got this problem. I know How to use copy memory API using DllCall.

the problem it's that I just want to copy a value "text" from a Pointer to my variable. bot I don't know how too.

In vb6 I would do it so

CopyMemory ByVal StrPtr(FilePath), ByVal CallWindowProc(VarPtr(ASMBYTE(0)), 0, 0, 0, 0), 255

but I don't know sure how to get a ptr. I think maybe createing a structure but not sure how.

I hope you understand :S look complicated.

How it's this related to AutoIt? If it is then check out DllStructCreate() function, maybe this is what you need.

I know that I need to use dll call.

But I don't know the exactly way to do that I want.

I mean make tow structures. struct1 with some value. and struct2 empty.

then use copymemory to pass the value of struct1 to struct2 by pointers.

and then be able to use dlstructure get data and my struct2 should have the value same struct1.

but don't know how to start.

sorry for my bad english.

I'm sorry. I thought, I should bump.

Please Close Topic.

Danyfirex,

There is no need to close it - just do not bump it again before this time tomorrow.

Maybe give this a try:

$tStruct = DllStructCreate("WCHAR[260]", $ptr)
$sVar = DllStructGetData($tStruct, 1)

Maybe give this a try:

$tStruct = DllStructCreate("WCHAR[260]", $ptr)
$sVar = DllStructGetData($tStruct, 1)

I feel stupid. it was easiest that I thought.

thank you so much KaFu

here result.

$tStruct1 = DllStructCreate("WCHAR[260]")
DllStructSetData($tStruct1,1,"Hola Mundo") 
$sVar1 = DllStructGetData($tStruct1, 1)

$ptr=DllStructGetPtr($tStruct1,1)

msgbox(0,"",$sVar1) 


$tStruct = DllStructCreate("WCHAR[260]",$ptr)

$sVar = DllStructGetData($tStruct, 1) 

msgbox(0,"",$sVar)

thank you so much.

Are you sure that is the behaviour you want, nothing is being copied is it?

$tStruct1 = DllStructCreate("WCHAR[260]")
DllStructSetData($tStruct1,1,"Hola Mundo")
$sVar1 = DllStructGetData($tStruct1, 1)

$ptr=DllStructGetPtr($tStruct1,1)

msgbox(0,"",$sVar1)


$tStruct = DllStructCreate("WCHAR[260]",$ptr)
DllStructSetData($tStruct1,1,"Bye Mundo")
$sVar = DllStructGetData($tStruct, 1)

msgbox(0,"",$sVar)

$sVar = DllStructGetData($tStruct, 1)

msgbox(0,"",$sVar)

yes this that I want, no need to be copy I wanted to get the the string by the ptr. its work. or there is some best way?

obvious then I will use copymemory to copy in another block.
