If it's of any use to you, here is a function I wrote to handle various ways 
of invoking external processes:

//---------------------------------------------------------------------------
static bool StartProcess( LPCSTR lpszImageName,
                          LPCSTR lpszCommandLine,
                          bool bWaitFinish=true,
                          PHANDLE phProcess=NULL,
                          DWORD *pProcessId=NULL,
                          PHANDLE phThread=NULL,
                          DWORD *pThreadId=NULL,
                          DWORD *pExitCode=NULL )
{
  DWORD dwExitCode = 0;

  /* Structures necessary for open/close process */
 PROCESS_INFORMATION ProcInfo;
  STARTUPINFO StartInfo;
  memset( &StartInfo, 0, sizeof(STARTUPINFO) );
  StartInfo.cb = sizeof(STARTUPINFO);

  if (!CreateProcess( (LPSTR)lpszImageName,
                    (LPSTR)lpszCommandLine,
                    NULL,
                    NULL,
                    TRUE,
                    DETACHED_PROCESS|NORMAL_PRIORITY_CLASS,
                    NULL,
                    NULL,
                    &StartInfo,
                    &ProcInfo ))
  {
    return false;
 }
  else
  {
    if ( phProcess != NULL ) *phProcess = ProcInfo.hProcess;
    if ( phThread != NULL ) *phThread = ProcInfo.hThread;
    if ( pProcessId != NULL ) *pProcessId = ProcInfo.dwProcessId;
    if ( pThreadId != NULL ) *pThreadId = ProcInfo.dwThreadId;
    if ( bWaitFinish )  // if we want to wait for this process to complete 
before returning
    {
      if ( WaitForSingleObject( ProcInfo.hProcess, INFINITE) != 
WAIT_FAILED )
      {
        GetExitCodeProcess( ProcInfo.hProcess, &dwExitCode );
      }
      CloseHandle( ProcInfo.hProcess );
      ProcInfo.hProcess = NULL;
      CloseHandle( ProcInfo.hThread );
      ProcInfo.hThread = NULL;
    }
    else
    {
      if ( phProcess == NULL )
      {
        CloseHandle( ProcInfo.hProcess );
        ProcInfo.hProcess = NULL;
      }
      if ( phThread == NULL )
      {
        CloseHandle( ProcInfo.hThread );
        ProcInfo.hThread = NULL;
      }
    }
  }
  if ( pExitCode != NULL ) *pExitCode = dwExitCode;
  return true;
}
