DWORD registry value of "ffffffff"

[JimHolland]

I'm trying to add a DWORD registry entry with a hex value of "ffffffff".

WshShell.Regwrite"HKEY_CLASSES_ROOT\Path\Path\Path\Key", ffffffff, "REG_DWORD"

but it is not being populated. It's fine if I use zero - but it ignores it when I use the hex value. Can anyone help me out?

More specifically - I'm getting an overflow error 800A0006 as the DWORD value i'm trying to create is "4294967295".

Does anyone know how I would be able to get around this..?

there's a limit on the size of dword you can write. 4 bytes is the limit. dunno how this equates to your number tho.

Have you tried this ?
WshShell.Regwrite "HKEY_CLASSES_ROOT\Path\Path\Path\Key", -1, "REG_DWORD"
or this:
WshShell.Regwrite "HKEY_CLASSES_ROOT\Path\Path\Path\Key", CLng(&Hffffffff), "REG_DWORD"


Hope This Help

Hello JimHolland,

If it is a REG_DWORD value, you only need to input the correct hexadecimal format which is &HFFFFFFFF.

WshShell.Regwrite "HKEY_CLASSES_ROOT\Path\Path\Path\Key", &Hffffffff, "REG_DWORD"

No reason of it not working.

Besides, when I cut and paste your line, I see there is not a space separating .Regwrite and the "HKEY_...". Is it just a typo? (I hope so.)

I can't seem to find the relevant link, but there is an issue with 32-bit values in VBScript. VBScript treats the first bit as a sign bit, so in reality the values are only 31-bits long. To get around this, append an additional ampersand, "&", to the end of the word.

WshShell.Regwrite"HKEY_CLASSES_ROOT\Path\Path\Path\Key", &Hffffffff&, "REG_DWORD"

I asked the same question a week ago and PHV gave the best suggestion. use -1 as the value you are setting. When you look at it in the registry you will see that it will read as FFFFFFFF.

Hello all,

If it is _"REG_WORD", &HFFFFFFFF is no problem at all. If you actually want "REG_BINARY" that is another matter that I had dealt with it previously.
