ReadProcessMemory + address from ollydbg

[bauss via Digitalmars-d-learn]

I'm currently getting garbage data when using ReadProcessMemory 
to read from another process.

This is my definition:
BOOL ReadProcessMemory(HANDLE hProcess, LPCVOID lpBaseAddress, 
LPVOID lpBuffer, SIZE_T nSize, SIZE_T *lpNumberOfBytesRead);

And I'm reading it like this:
if (!ReadProcessMemory(process,
       cast(PCVOID)address, cast(PVOID)&data,
       cast(DWORD)stringSize, cast(PDWORD)&bytesRead)) {
       return defaultValue;
     }

process is a HANDLE that I got from OpenProcess()
address is a DWORD
data is char[1024]
stringSize is size_t
bytesRead is PDWORD

The address I obtained was from Ollydbg and it's a static 
address. I'm not sure if I however need some kind of offset etc.

I tried to search and found you might have to use 
GetModuleHandleA() but I tried that and I still get garbage data 
with the offset from that.

What am I doing wrong?
