(was: unsigned int = 4
{color:#172b4d} unsigned int* = 8{color}
{color:#172b4d} LPDWORD = 8{color}
{color:#172b4d} LPDWORD* = 8{color}
{color:#172b4d} DWORD = 4{color}
{color:#172b4d} DWORD* = 8{color}
{color:#172b4d} unsigned long = 4{color}
{color:#172b4d} unsigned long* = 8{color}
{color:#172b4d}is a DWORD pointer, that's 8 not 4.{color}
{color:#172b4d}DWORD *pMemory = {color}{color:#172b4d}(DWORD *{color})
{color:#172b4d}malloc (1000);{color}
{color:#172b4d}*pMemory = 0; // this over writes 64 bits not 32 bits. Try it in
a debugger if you are in any doubt. this is what happens inside ::Reg. There is
only 32 bits on the stack.{color}
I cant help much more but point you in the correct direction.....sorry!
