问题 I have an winmain application that is executed from cmd.exe and prints output to it. I atach to the cmd.exe using AttachConsole(ATTACH_PARENT_PROCESS) .

Before closing my application I release the console using FreeConsole() . #include <iostream> #include <fstream> #include <windows.h> int wWinMain ( HINSTANCE hInstance,

问题 I wrote the following JavaScipt code which converts a binary number into a decimal number: (function bin_dec(num) { var x = num; var result = 0; for (var i = 0; i < x.length; i++) { result += eval(x[x.length - i] * 2^i); } return result; })() I want to be able to run this code from the command-line. The filename is converter.js and I am running the command prompt window in the same directory as the file. I am trying to run this code using 01001100 as the function argument. Here are my

问题 The (unofficial) documentation for the Windows Internal CMD ECHO shows some interesting tricks in it. However, I have not yet found a way to echo a single character . Quick note, od used below, is from a Git (or Gow) installation For instance, this echo's the 'a' with a 'windows' newline ( \r\n ): >echo a| od -A x -t x1z -v - 000000 61 0d 0a >a..< 000003 And this trick (also in the docs now) echo's nothing: ><nul (set/p _any_variable=)| od -A x -t x1z -v - 000000 So I would expect this to

But when I tried to check on C:\Program Files\Java\ directory, I don't seem to find the same version. I only see the following: j2re1.4 jdk1.6.0_32 jdk1.7.0_06 jdk1.7.0_07 jre6 jre7 And so on... My programs still run, but I'm just trying to compile everything manually, and understand how Java is being treated by the OS. Another thing that is weird is, I tried to
