I would like to know how to do conversions from hex to decimal, i know how to do it by hand, i mean in a program is there a function that will let you automatically take a number from hex to decimal and back again.
More importntly, I would like to be able to read a hex string, and display it as assci in an edit box or display box
then take any changes and writh them back in to mem as hex.

dionysus,
if i've understood well, you want do dispaly an HEX number as string, in a edit control.
First possibility:
This routine i found somewhere translate a value in a byte to his HEX as string.
Second possibility:
to use something already in api like
_wsprintfA
could try:
Format1 db "%lX",0
call _wsprintfA, offset output1, offset Format1, Value
