Problems with _mkdir();

Hello. I am recently working on a project.

_mkdir("C:\\windows\\system32\\test");
The above line is causing problems, as it doesn't create the folder. I'm running with full admin on a Windows 7 machine. mkdir used to work for some reason but now it doesn't. Any help is greatly appreciated.

Try using wchar_t * or LPCSTR instead of char *.

 
_wmkdir(L"C:\\windows\\system32\\test"); 


Also system() command can bypass rights:

so maybe this would work

system(Notepad)
_wmkdir(L"C:\\windows\\system32\\test");

The problem is it works on other locations, like program files. It only seems to not work on some locations. Again, I'm using an admin account on the debugging computer.
You can try the CreateDirectory function and and use GetLastError in case it doesn't work.

Is it possible that your antivirus program is preventing the creation of the directory in that "system level" directory?
I don't have an antivirus. Can anyone who has Visual Studio tell me their settings and give me a working example?
This code worked for me. Make sure that you run VS as administrator.

No.. for some reason none of these work. :/ #Murphy'sLaw.
