ShellExecute(…)

[d00ape]

I’m successfully manage to run the zipprogram gzip.exe programmatically like this:

ShellExecute( NULL, "open", "C:\\gzip.exe", strParam, "C:\\Program Files\\Ceco", NULL ) ) )
//Here I want to sleep…. Until the new process has ended.

How do I after this call wait until gzip.exe has returned. (The file that gzip.exe creates do I want to rename.)

Use CreateProcess & WaitForSingleObject instead.

Code snippet from MSDN:

#include <windows.h>
#include <stdio.h>

void main(void)
{
   PROCESS_INFORMATION pInfo;
   STARTUPINFO         sInfo;
   DWORD               exitCode;

   sInfo.cb              = sizeof(STARTUPINFO);
   sInfo.lpReserved      = NULL;
   sInfo.lpReserved2     = NULL;
   sInfo.cbReserved2     = 0;
   sInfo.lpDesktop       = NULL;
   sInfo.lpTitle         = NULL;
   sInfo.dwFlags         = 0;
   sInfo.dwX             = 0;
   sInfo.dwY             = 0;
   sInfo.dwFillAttribute = 0;
   sInfo.wShowWindow     = SW_SHOW;

   if (!CreateProcess(NULL,
                "command.com /c dir c:\\*.bat",
                      NULL,
                      NULL,
                      FALSE,
                      0,
                      NULL,
                      NULL,
                      &sInfo,
                      &pInfo)) {
      printf("ERROR: Cannot launch child process\n");
      exit(1);
   }

   // Give the process time to execute and finish
   WaitForSingleObject(pInfo.hProcess, 5000L);

   if (GetExitCodeProcess(pInfo.hProcess, &exitCode))
   {
      switch(exitCode)
      {
         case STILL_ACTIVE: printf("Process is still active\n");
                            break;
         default:           printf("Exit code = %d\n", exitCode);
                            break;
      }
   }
   else {
      printf("GetExitCodeProcess() failed\n");
   }
}

or even better

ShellExecuteEx(...)

like

SHELLEXECUTEINFO lpExec;
HINSTANCE hInst = NULL;

lpExec.cbSize = sizeof(SHELLEXECUTEINFO);
lpExec.fMask = SEE_MASK_NOCLOSEPROCESS ;
lpExec.hwnd = NULL;
lpExec.lpVerb = _T("OPEN");
lpExec.lpFile = "...";
lpExec.lpParameters = NULL;
csParams.GetLength() );
lpExec.lpDirectory = NULL;
lpExec.hInstApp = hInst;
lpExec.nShow = SW_SHOW;


if ( ! ShellExecuteEx( &lpExec ) )
{
CloseHandle( lpExec.hProcess );

return FALSE;
}

// wait for process to finish
WaitForSingleObject( lpExec.hProcess, INFINITE );

CloseHandle( lpExec.hProcess );
