>Does VFP have function to convert Decimals values to Hexadecimals values?

Jean-Rene,

As Nigel pointed out the TRANSFORM() function can do this, but there's extra work involved if the value is less than zero, you'll get stars (overflow). Try this out from the command window:

lnval = 0xFFFFFFFF
? lnval && 4294967295
? TRANSFORM(lnval, "@0x") && 0xFFFFFFFF
lnval = BITOR(lnval, lnval)
? lnval && -1
? TRANSFORM(lnval, "@0x") && **********

So it all depends on whether or not it's a signed integer, which as the code shows can happen without you're being aware of it.
