Read datatype of registry

[kaul1jos]

Hi,

I'd like to read the registry and check what datatype DevicePath is.

I tried the standard scripting from Microsoft but then I got just the whole key CurrentVersion.

So I like to check if HKLM\Software\Microsoft\Windows\CurrentVersion\DevicePath is from the REG_EXPAND_SZ type. If this is not I would like to change it to this datatype.

Please help!!

Hello kaul1jos,

You can use wmi stdregprov to bind to the key containing the value. Then use .enumvalue method and read out the index of the valuename you are interested in from the out-array of valuename. From the index, you can read the value-type from the out-array of valuetype.

const HKLM=&h80000002
onst REG_SZ = 1
const REG_EXPAND_SZ = 2
const REG_BINARY = 3
const REG_DWORD = 4
const REG_MULTI_SZ = 7

skey="Software\Microsoft\Windows\CurrentVersion"
svname="DevicePath"
set regsvc=getobject("winmgmts:root\default:stdregprov")
iret=regsvc.enumvalue(HKLM,skey,avname,avtype)
if iret=0 then
    for i=0 to ubound(avname)
        if strcomp(avname(i),svname,1)=0 then
            wscript.echo "value name: " & skey & "\" & svname & vbcrlf & "value type: " & avtype(i)
            exit for
        end if
    next
end if
set regsvc=nothing

I list also the constants reflecting the value type (REG_SZ) etc. When you read avtype(i) the value corresponds to the commonly known type by these constant's names.
