so, my address in ce is
this is what ive done so far
| Quote: |
LONG hackhex;
LONG *hackbase = (LONG*)0x342D8120;
LONG *hack1;
hackhex = *hackbase; |
I think this gives hackhex the value of hackbase in Decimal, but how do i change it to HEX?

| Code: | | DWORD dwPtrVal = *((DWORD*)0x342D8120+0x13); |
If you want to view it in hex, output your string in hex instead...
| Code: | LPTSTR lpText = (LPTSTR)HeapAlloc(GetProcessHeap(), 0, sizeof(TCHAR)*64);
wsprintf(lpText, _T("Hex: 0x%X/Dec: %d"), dwPtrVal, dwPtrVal);
MessageBox(hWnd, lpText, _T("dwPtrVal"), MB_OK);
HeapFree(GetProcessHeap(), 0, (LPVOID)lpText); |

Give 0x342D8120+0x13 = 342d8133?
I want the value of 0x342D8120 into a hex(address) and that address + 0x13.

No, pointers work diffrently.
A pointer points to the base address value + the offset.
And there's no such thing as "hex" values or "decimal" values, everything is binary, it's just the way you output the strings is diffrent, as lurc showed.

| A pointer doesn't have to be static, it could be a pointer to a pointer to a pointer..... to a pointer.

dwPtrVal = *(DWORD*)0x0100BECC+0x100;
and then the value is 16777216 which is 0x01000000 the correct one.
so..i meant how do i change the value of value of dwPtrVal...

ok thanks for your help.. it works perfectly now i can complete my dll ^^ btw i like your maplestory trainer
okay now, how do i get the value of a TEXT address into C++, i need to compare it with another text, ive tried string but it fails with this error
| Quote: | | if ( *(string*)( *(DWORD*)dwID + dwIDOff) == ID ) { |
| Quote: | c:\documents and settings\mathew\my documents\visual studio 2008\projects\matt\matt\dllmain.cpp(94) : error C2678: binary '==' : no operator found which takes a left-hand operand of type 'std::string' (or there is no acceptable conversion)
c:\program files\microsoft sdks\windows\v6.0a\include\guiddef.h(192): could be 'int operator ==(const GUID &,const GUID &)'

LPCTSTR GG;
GG = (LPCTSTR)*(DWORD*) (*(DWORD*)dwID + dwIDOff);
if ( lstrcmp(GG,ID) == 0 ) {
do function
}

crashes me...i think its beause of the
| Quote: | | (LPCTSTR)*(DWORD*) (*(DWORD*)dwID + dwIDOff) |
part...the address are 100% correct.
