Executing CMD commands using C++

Question

I am trying to sleep my PC using this command

system("C:\\Windows\\System32\\psshutdown -d -t 0");

it works fine if I use cmd, but when I run this in cpp, I got this

'C:\Windows\System32\psshutdown' is not recognized as an internal or external command, operable program or batch file.

Answer 1

32-bit applications running on WOW64 will be put under file system redirection . Therefore if your app is a 32-bit one, the call system("C:\\\\Windows\\\\System32\\\\psshutdown -d -t 0"); will look for psshutdown.exe in C:\\Windows\\SysWOW64 and failed. You have some solutions:

• Use Sysnative instead to access the real System32 folder: system(R"(C:\\Windows\\Sysnative\\psshutdown -d -t 0)");
• Turn off file system redirection explicitly (should be avoided in general)
• Or better recompile your app as a 64-bit application
