Win32API - How to get file name of process from process handle?

Question

How can I get the file name of process from a process handle? I'm using Win32 C++ (Visual C++ Express Edition).

Thanks.

Answer 1

Call GetModuleFileNameEx. Available as of Windows 2000.

DWORD WINAPI GetModuleFileNameEx(
  __in      HANDLE hProcess,
  __in_opt  HMODULE hModule,
  __out     LPTSTR lpFilename,
  __in      DWORD nSize
);

Use NULL for the second parameter to get the name of the EXE file.

Answer 2

The GetProcessImageFileName function retrieves the name of the executable file for the specified process handle (WinXP, Server 2k3 or later), as does QueryFullProcessImageName for Vista and 2k8 or later.
