compiler construction - Lua crashes when programs are compiled -

-

i'm working on very, simple lua program, trying teach myself language. here's 3 line program:

file = io.open("hello.txt", "w") file:write("hello, world.\n") io.close(file)

when use program lua script, works fine. when compile program, works. however, when run compiled program, this:

i'm using lua 5.1.2 on windows xp on pentium 4. uninstalled lua , re-installed it, no effect. i'm compiling script follows:

luac -o hello.exe hello.lua

am doing wrong, or known bug? i'd able write lua programs run on computers without lua installed. help! (and thanks!)

luac doesn't compile system exe file. take lua script, , turn lua bytecode. still have pass resulting file lua execute.

so exe file contains garbage os point of view. when exe files don't contain valid exe headers, os reason decides must old style dos .com file , tries execute 16bit dos subsystem. hence strange error message.

if want make exe out of compiled lua need use different environment - perhaps visual studio - make small project loads (and executes) lua file - compiled or script - using embedded lualib.

creating standalone lua executables on stackoverflow has tips on how go that.

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

C#: Application without a window or taskbar item (background app) that can still use Console.WriteLine() -

i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() . (i.e. if executes app command prompt write console.) the problem if create windows form (or wpf) application can have there no taskbar, console or window show up, console.writeline() nothing. if create console app, writes console, can't figure out how hide (and if did hide it, write command prompt window?)... how do this? just create standard console application. callers responsibility hide window caused program (from how run c# console application console hidden ): system.diagnostics.processstartinfo start = new system.diagnostics.processstartinfo(); start.filename = dir + @"\myprocesstostart.exe"; start.windowstyle = system.diagnostics.processwindowstyle.hidden;
