hey there little cracker..

there are more a couple of possibilities

1. my old favorite the hex editor (just download a free one)
2. resourcehacker (editing the dialogs, strings and bitmaps in windows executables)
3. a decompiler..

A hex editor displays the contents of a file in hex format (0,1,2,3 etc to F) allong with the normal (ascii) format and lets you edit the file that way.. nothing more..
Resourcehacker will allow you to mangle windows apps and make your own little adjustments to the look and feel..
A decompiler can convert the executable back to a disassembled state, this is in no way nice readable sourcecode, but you could edit the disassambled remains and re-assamble them..

well that was all the help for now..

Could you on your part enlighten the board on your intentions with the ability to edit exe's?
