; i'm not sure if u can do that in "PE explorer"
; but in e.g.: OllyDBG you can edit the disassembled code of a ;program and then copy it to the .exe file "selection"->"copy to ;executable"

; here is a simple encrypting/decrypting app.:
; on encryption it will just inc hex values represented byeach char

then you have to "inc si" and "jmp orderab" before "finish"

; you have to allocate enough memory for the string in the ".data?" ; section:
.data?

; then when you call StdIn it will write user input into szBuff

; you mean storing it even after program close?
; then : In Registry (RegOpenKeyEx, RegQueryValueEx, RegSetValueEx ...) , In a File ( CreateFile, WriteFile, ReadFile ...), In .ini File ( you can...

; do you want later to decrypt it back or no?

; hi.
; it will jump if eax is greater.
; "jg" is the opposite

Yes I think so. If you want post your code here and we'll see.

;Hi.
;Actually why did you compare eax with -9999 ?
cmp eax,-9999 ;?

;stdcall is pushing on the stack values in the opposite...
