WriteProcessMemory not working for me...

<< < (2/2)

440bx:
Did you first check that OpenProcess was successful ?

CodeSculptor:
To answer questions, YES, I did check to see that the process was open.

And the biggest clue was Martin_fr's comment regarding : "LastError"...

The 998 showed it was lack of permission to mod memory..

So the NEW write is now working as (oldSettings is : DWORD ) :

VirtualProtectEx( Process_Handle,
                           Pointer( Heap_Byte_Address ),
                           2,
                           PAGE_EXECUTE_READWRITE,
                           @oldSettings );

         
         
         WriteProcessMemory( Process_Handle, 
                                               Pointer( Heap_Byte_Address ),
                             @tmpByte_Array,
                             2, 
                             HowManyBytesWritten );

         VirtualProtectEx( Process_Handle,
                           Pointer( Heap_Byte_Address ),
                           2,
                           oldSettings,
                           @oldSettings);                 



Thanks everyone :)
