hallo, ich will eine keine Anwendung schreiben, bzw hab sie geschrieben( funktioniert nur net) mit der man per VirtualProtectEx() die protection-Flags im speicher neu setzen kann. ZIEL PAGE_GUARD auszuschalten.
hier mal der code:
wenn ihr mir sagen könnt wo mein fehler liegt, wieso des immer fahlschlägt, dann sagts mir... bin fuer jede Hilfe dankbar.
Gruß Tobi.
hier mal der code:

Project : Kill PAGE_GUARD
File : KillPG.cpp
Remark : Many memory addresses will protected by PAGE_GUARD, if you want to
manipulate or read an address, PAGE_GUARD cause an exception, so
you got no access.
This application should turn off the fucking PAGE_GUARD.

, denn in dem Code kann so ziemlich viel schiefgehen.
