Determining the type of RegRead() data?

[LxP]

Hi guys,

I'm an old AutoIt v2.x user who has just been made aware of version 3 with GUI support and everything! It's truly amazing -- goodbye to things like Visual DialogScript and WinBatch! I can't wait to do some heavy stuff with it.

Congratulations and thanks to everyone who has been involved in getting AutoIt this far.

I've created a thread similar to this in the Idea Lab forum but perhaps someone can offer me a workaround in the meantime if I post here as well.

I would like to be able to identify the type of information returned by a RegRead() (REG_SZ, REG_DWORD, etc.) but there appears to be no way to determine this via AutoIt. Is anyone aware of a solution to this that doesn't require the use of an external utility?

Regards,

Alex Peters

go to help in autoit v3 ( normally through sciTe)

type in registry under search and you will get more info on these

RegWrite ( "keyname" [,"valuename", "type", value] )

RegRead ( "keyname", "valuename" )

hope that helps

Thanks for that fast response!

I don't think I've phrased myself very well. Let's assume that a RegRead() results in the string "1234" -- how do you determine whether this was REG_SZ ("1234"), REG_DWORD (dword:000004d2) or REG_BINARY (hex:12,34) data?

Any of the above data samples will result in a RegRead() return of "1234" and in order to create an identical key in another location, you need to specify the data type to be used (which is unknown to the script because it's lost).

Does this better explain what I'm trying to achieve?

how about this

Regread("HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main", "Window Title", "REG_SZ", $I_Title_set)

if error... then

if $I_Title_set >="" then...

**** and

Regread("HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main", "Window Title", "??????", $I_Title_set)

if error... then

if $I_Title_set >="" then...

i've used the first one and it works for me

just error test if your program doesn't know if it exists

hope that helps

Regread("HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main", "Window Title", "REG_SZ", $I_Title_set)

Unfortunately AutoIt says that 3 or 4 is an incorrect number of parameters. It only seems to want 2.

Is this possibly some sort of not-yet-documented feature which I'm using incorrectly? The help page only lists two valid parameters: RegRead($KeyName, $ValueName).

I noticed that also went i went to look for an example to show you

but.... i found one in one of my programs and yes.... it works

it is in this program.... just search "regread"

That's true, there are onyl 2 parameters!

@Valuater: Please post your whole script. I don't think it is an AU3 script. I get the same error with official and beta release. AND in the source code there are definitely only two parameters for RegRead !??!

Cheers

No problem Valuater, thanks for sticking with me this far! Just to be clear to everyone on what I'm trying to achieve here's a code segment with some missing pieces and hopefully someone can fill in the blanks.

; The following code copies a specific name/value pair
; from one location in the registry to another, as
; specified by $sourceKey and $targetKey.

func regDataType($key, $name)

    if (...) then return "REG_BINARY"
    if (...) then return "REG_DWORD"
    if (...) then return "REG_EXPAND_SZ"
    if (...) then return "REG_MULTI_SZ"
    if (...) then return "REG_SZ"

endFunc

local $sourceKey = "HKCU\Software\Key 1"
local $targetKey = "HKCU\Software\Key 2"

local $name = "ArbitraryData"
local $value = regRead($sourceKey, $name)

local $dataType = regDataType($sourceKey, $name)
regWrite($targetKey, $name, $dataType, $value)

Thanks to all for your attention!

Regards,

Alex

local $dataType = regDataType($sourceKey, $name)

I just wrote such a function and submitted it to the development group. Function: RegGetValType().

It might or might not appear in one of the next beta snapshots. Keep watching....

Thanks Kurt, you're the man (I hope)! Alternatively the data type information could be returned via the @Extended macro when calling RegRead()? Then no further function would be needed:

local $sourceKey = "HKCU\Software\Key 1"
local $targetKey = "HKCU\Software\Key 2"

local $name = "ArbitraryData"
local $value = regRead($sourceKey, $name)
local $extended = @extended

local $dataType
if ($extended = 0) then $dataType = "REG_BINARY"
if ($extended = 1) then $dataType = "REG_DWORD"
if ($extended = 2) then $dataType = "REG_EXPAND_SZ"
if ($extended = 3) then $dataType = "REG_MULTI_SZ"
if ($extended = 4) then $dataType = "REG_SZ"

regWrite($targetKey, $name, $dataType, $value)

Soon I'll be able to program that recursive registry key graft routine! Victory will be mine!

Alex
