How do I pass path with space to the CreateProcess() function? The following works STARTUPINFO si; PROCESS_INFORMATION pi; ZeroMemory( &si, sizeof(si) ); si.cb = sizeof(si); ZeroMemory( &pi, sizeof(pi) ); if( !CreateProcess(_T("c:\\installer\\ew3d.exe"), // No module name (use command line) _T("c:\\installer\\ew3d.exe /qr"),//argv[1], // Command line NULL, // Process handle not inheritable NULL, // Thread handle not inheritable FALSE, // Set handle inheritance to FALSE 0, // No creation flags NULL, // Use parent's environment block NULL, // Use parent's starting directory &si, // Pointer to STARTUPINFO structure &pi ) // Pointer to PROCESS_INFORMATION structure ) { printf( "CreateProcess failed (%d).\n", GetLastError() ); return false; } //Wait until child process exits. WaitForSingleObject( pi.hProcess, INFINITE ); // Close process and thread handles. CloseHandle( pi.hProcess ); CloseHandle( pi.hThread ); But if I use a path with space as as the code below, it didn't work. CreateProcess(_T("c:\\master installer\\ew3d.exe"), // No module name (use command line) _T("c:\\master installer\\ew3d.exe /qr"),//argv[1], // Command line NULL, // Process handle not inheritable NULL, // Thread handle not inheritable FALSE, // Set handle inheritance to FALSE 0, // No creation flags NULL, // Use p
