I tansformed Kev's lib for Registry from B+ to B3D code.
It uses ID numbers for the Registry modules (eg. HKEY_CURRENT_USER=$80000001), but Blitz3D doens't support such big numbers, so it changes them to negative numbers.
Is there a way to get bigger integers in Blitz3D?

Does it matter if Blitz thinks the numbers are negative?

That code is for BlitzPlus, which uses the same integers as Blitz3D.

I'm sorry but a 32bit INT is very valid in Blitz3D. What you see is a hex value $80000001. Hex values in 32bit goes from 00000000 to FFFFFFFF. I would be careful with that stuff. if you have trouble interpreting hex values and 32 bit ints, I wouldn't even try converting a lib that plays with the registry! Playing with the registry is very complex and you can corrupt it, meaning you could break your windows installation.

Floyd is right. It doesn't matter what B3D thinks the number is. It's only a 32 bit value that you're trying to hold and you've got 32 bits to store it in. If it worked in BlitzPlus, it'll work in B3D.

If you need anything bigger you could store it in a bank

Hi

try:

anInteger = $80000001

Print anInteger

Print Hex(anInteger)

WaitKey()

you'll see that the variable holds the correct value

hope that help's you

Or use a string to load the number. Pretty slow though, as i found out :o)
