convert hex registry key to decimal

[lapa]

hello there,

the folling two lines represent an export from a registry
key.

[HKEY_LOCAL_MACHINE\SYSTEM\...\Ac97]
"MasterVolume"=hex:07,07

i would like to use the value in a script as a decimal
value. sadly i did not find any solution for this yet.

i would appreciate any help.

thank you,

lapa

You can't use that as a decimal; it is a binary. You CAN write binary
values to the registry. Using WSH-hosted VBScript, for example:

Set WshShell = CreateObject("WScript.Shell")
WshShell.RegWrite "HKLM\SYSTEM\...\Ac97\MasterVolume", &H0707, "REG_BINARY"

is there any way to use the value for an 'if' decision? as
i have tried with RegRead, i got a type mismatch error.

it would be enough to know if its equal to sg. (i would
like to know if the current volume level equals one of 5
predefined values to fade the volume level from one to
another. the current value is the only thing i miss for
the code...

thanks again.

Hi

I think this should work:

Set oShell = CreateObject("WScript.Shell")

sRegValue = "HKLM\SYSTEM\.........\Ac97\MasterVolume"

aRegData = oShell.RegRead(sRegValue)

For i = 0 To UBound(aRegData)
vHexVal = vHexVal & Right("0" & Hex(aRegData(i)), 2)
Next

WScript.Echo CLng("&H" & vHexVal)
