Device Driver Version (win32 device management/device services)

How can I find the version of a device driver?

SetupDiGetDeviceRegistryProperty does not seem to be what I want because none of the SPDRP_... constants include anything about version information.

How does the device manager for windows do it, for example?

You can read the version number directly from the binary, see http://support.microsoft.com/kb/167597 ("SAMPLE: GetVers.exe Specifies Component FileVersion and #Version"). The scoop is to
#include <windows.h>
#include <iostream>
#pragma comment ( lib, "version.lib")
 
using namespace std;
 
   void reportError()
   {
       LPVOID lpMsgBuf;
 
       FormatMessage(
           FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM,
           NULL,
           GetLastError(),
           MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
           (LPTSTR) &lpMsgBuf,
           0,
           NULL );
 
       cout << (char*)lpMsgBuf << "\n";
 
       // Free the buffer.
       LocalFree( lpMsgBuf );
   }
 
   void main( int argc, char *argv[ ], char *envp[ ] )
   {
       cout << "\n";
 
       if(2 != argc)
       {
           cout << "Syntax: GetVer <File Name>\n";
           return;
       }
 
       DWORD dwArg;
       DWORD dwInfoSize = GetFileVersionInfoSize(argv[1], &dwArg);
 
       if(0 == dwInfoSize)
       {
           cout << "No version info available\n";
           reportError();
           return;
       }
 
       BYTE* lpBuff = new BYTE[dwInfoSize];
 
       if(!lpBuff)
       {
           cout << "Out of Memory\n";
           return;
       }
 
       if(0 == GetFileVersionInfo(argv[1], 0, dwInfoSize, lpBuff))
       {
           cout << "Error retrieving version info\n";
           reportError();
           return;
       }
 
       VS_FIXEDFILEINFO *vInfo;
 
       UINT uInfoSize;
 
       if(0 == VerQueryValue(lpBuff, TEXT("\\"),
               (LPVOID*)&vInfo,
               &uInfoSize))
       {
           cout << "Version information not available\n";
           delete lpBuff;
           return;
       }
 
       if(0 == uInfoSize)
       {
           cout << "Version information not available\n";
           delete lpBuff;
           return;
       }
 
       cout << argv[1]
           << " Version: "
           << HIWORD(vInfo->dwFileVersionMS) << ","
           << LOWORD(vInfo->dwFileVersionMS) << ","
           << HIWORD(vInfo->dwFileVersionLS) << ","
           << LOWORD(vInfo->dwFileVersionLS) << "\n";
 
       delete lpBuff;
   }
