Type Conversions

Ok Im Rather New To Delphi So I Ask Of Your Help.

Im Trying To Log Functions Parameters To File By Hooking It, But i aint too sure how to format pointers and hex data into a string.


Heres the function  def...
 
HANDLE hProcess,  // handle to process whose memory is written to
LPVOID lpBaseAddress, // address to start writing to
LPVOID lpBuffer, // pointer to buffer to write data to
DWORD nSize, // number of bytes to write
LPDWORD lpNumberOfBytesWritten  // actual number of bytes written

handle = cardinal?
dword = cardinal?
lpvoid = pointer?
lpdword = pdword?

 
i tried..

FmtStr(TheParams,'%d, %.x, %.x, %d, %d', [hProcess, lpBaseAddress, lpBuffer, nSize, lpNumberOfBytesWritten]);

but still crashes :/




Thanks.
