I have the ID of a process and I want to find out the location of the
executable on the harddisk for that process.

I'm aware of the method:

DWORD GetModuleFileName(
  HMODULE hModule,    // handle to module to find filename for
  LPTSTR lpFilename,  // pointer to buffer to receive module path
  DWORD nSize         // size of buffer, in characters
);

but that relies on having a HMODULE and

HANDLE OpenProcess(
  DWORD dwDesiredAccess,  // access flag
  BOOL bInheritHandle,    // handle inheritance flag
  DWORD dwProcessId       // process identifier
);

only supplies a HANDLE.  How can I do this?

Cheers
Stephen

Use OpenProcess() to get a handle to a process. Use EnumProcessModules() or
CreateToolhelp32Snapshot()/Module32First()/Module32Next() to get a list of
handles to modules. Pass the module handles to GetModuleFileNameEx().

Thanks alot.  In order to use EnumProcessModules and GetModuleFileNameEx, I
have to install PSAPI from the Platform SDK right?

You are welcome.

The MSDN-CD and the web site at http://msdn.microsoft.com  is chock full of
useful information. You'll find this there about that: :-)

"These functions are available in Psapi.dll, which is included in Microsoft?
Windows? 2000 and Microsoft? Windows? XP. To use these functions on
Microsoft? Windows NT? 4.0, you must obtain the redistributable version of
this DLL."
