# Info : This exploit works only on WinXP SP1 because it is almost impossible to execute it on Win7 & WinXP SP2/SP3 cause This program has been compiled with SafeSEH enabled .
# So in other versions of Windows you will not find any valid UNICODE addresses (No SafeSEH) neither in OS modules nor in Program Modules .
# Anyway this exploit works perfectly on Windows XP SP1 .
# Here it is , the video explain the usage =) :  http://www.youtube.com/watch?v=pkOaPQJPQbE (Windows XP SP1 + Windows 7 )
###

# So first go to C:\program files\Internet Mobile\plugins\SMSUIPlugin\SMSUIPlugin_fr-fr.lang or _en-fr.lang (according to the program language)
# Then put the output of this perl program  in <item name="IDS_PLUGIN_NAME">HERE !!</item> . Save it open the program .
# Not like Win7 & WinXP SP2/SP3 this exploit requires you to click from the to menu "Operation" --> "Message texte" !! Bingo . Calc.exe Just Showed Up =) .
#                                                                               English :"Operation" --> "Text Message"
