_getch() doesn't work on windows server 2012

Question

I need a DLL for users can type password and not echo on the screen. So I use _getch() for getting chars with no echo like this,

        //get character with no echo
        ch = _getch();

and compile the code use microsoft vs2005.
It works on windows server 2003/2008, but on the new windows server 2012, it echos the characters to the screen.
My problem is why _getch() echo characters only on windows server 2012? and how to fix it?

Answer 1

使用cin.get（）代替getch（）。
