Use the parameter you would use for ShowWindow: i.e. SW_SHOWNORMAL.

Heres a way to start a program and either wait for to complete or continuing with the main process:

/************************************************************/
/* Execute a (DOS) command string or start a windows module */
/* The flag 'waitforit' causes the parent program to wait   */
/* until execution of the child completes if it is true.    */
/* otherwise the child is started and run concurrently.     */
/* The funtion returns the instance handle of the child.    */
/************************************************************/

HINSTANCE Cexecute_command(int waitforit,char *s)
   {
   unsigned int retval;
   int          r,inlist;
   LPSTR        com_str[256];
   char         ts[256];
   FILE         *ff;

#ifdef __WIN32__

   PROCESS_INFORMATION pi;
   STARTUPINFO         si;
   DWORD               exitcode;

#else

   TASKENTRY    lpte;
   HINSTANCE    task_instance;

#endif

   lstrcpy(com_str,s);

#ifndef __WIN32__

   task_instance=WinExec(com_str,SW_SHOWNORMAL);

   if(!waitforit)
      {
      return(task_instance);
      }

   /* Wait until the task has disappeared from the task list */

   lpte.dwSize=sizeof(TASKENTRY);
   while(TRUE)
      {
      inlist=FALSE;
      retval=TaskFirst(&lpte);
      if(!retval) break;                         /* If no first task, something is wrong */
      if(lpte.hInst==task_instance) inlist=TRUE;
      while((lpte.hNext)&&(!inlist))             /* Already found or still looking */
         {
         retval=TaskNext(&lpte);
         if(!retval) break;
         if(lpte.hInst==task_instance)
            {
            inlist=TRUE;
            break;
            }
         }
      if(!inlist) break;
      }
   return(task_instance);

#else

   /* Initialise the 'startup info' structure */

   si.cb=sizeof(si);
   si.lpReserved=NULL;
   si.lpDesktop=NULL;

   si.hStdOutput=0;
   si.hStdError=0;

   r=CreateProcess(NULL,
                   com_str,
                   NULL,
                   NULL,
                   FALSE,
                   (DWORD)NULL,
                   NULL,
                   NULL,
                   &si,            // Startup info
                   &pi);

   if(waitforit)
