How do we know by which programming language a program was written? how can we open and edit it?

Unless it's an open source application, chances are you won't be able to tell and you won't be able to edit it. When you download a program, you get an executable that's been compiled for your operating system. All you can do with that executable is run it. You can't edit the source.

Are programming using some computer language(Java, C++, etc.)? How are you trying to do this?

Should be written on the CD case that came with you computer, or a sticker somewhere on the CPU unit.\n\nYou can't get it out of the installed software alone, not without hacking it.

If you are using the linux or unix versions you can use the 'time' command which counts program execution time and reports it at the end of the run.. example would be 'time name_of_program_to_run' it would return something like this:\nreal    0m0.004s\nuser    0m0.001s\nsys     0m0.003s\nchris@digdug:~$\n\nif thats not an option you could probably come close by having the program spit out a timestamp at the beginning and end of the program.

older version of windows was written in c \n\nno doubt XP is written in cpp

This is a pretty weird question. How could anyone tell if we can't see your code? You're probably not a very good programmer if you can't spell "right answer". Do you speak english originally?

most the programming softwares has the option for that, just try to figure it o. I can't tell you cos i don't write c-programs

UN-INSTALL IT AND REINSTALL IT IN THE LANGUAGE YOU WANT. ON MOST PROGRAMS IT ASK YOU AT THE FIRST OF THE INSTALLATION WHAT LANGUAGE.

programming language use syntax as way to define instruction structure\n\nfor example, C++ language use ; as the end of an instruction. if u forget to type ; to end your instruction line, the compiler will generate that error.

It's easy but I need more details. Which programming language is it or which program was the invoice program made in? Perhaps you should also supply source code or program file. My email is tim0huxley@yahoo.com.sg

go to your program files and look for them

You may use any editor (VI, notepad, Visual Studio Express, Programmer's Editor, ...) to create source files (c/C++ files containing instructions to be compiled). \nDepending on the language of choice (C and C++ are different languages) name your file accordingly (c for the C Language, cpp, C, c++ or cxx for C++).\nThen compile, link (generally compilers do both things with a single command, you may use GCC for any platform, or Visual C++ Express from Microsoft for Windows -which is much easier to use) and run (just type the name of the program at the command line).\n\nSample. Write:\n\n#include <stdio.h>\nint Main(int argc, char* argv[])\n{\n   puts("Hello World!");\n   return 0;\n}\n\nthen save as "hello.cpp", \n\nany platform: compile with "gcc hello.cpp -ohello" and type "hello"\nWindows: if using MS Visual C++ Express, then just press F5

Im assuming you're currently looking at a source code...In that case, there's really a lot of factors you have to consider to identify which code came from which language. Different computer langauges offer some sort of uniqueness on the language syntax/construct itself, so that could be a factor for consideration. Other than that, there's just no definite way of precisely pointing out its source...Is it possible for you to post some snippet so that we can identify it together! =)

I would need to know what kind of file it is. Usually if your computer can't open it, it is because it is either an incompatible file, or  the program that created the file isn't on your computer.

In what programming language, please?

Depending on the language you feel most comfortable with.\nFor Fortran, C, C++ I suggest GNU tools.\nJava you can download from Sun for free.\nAs IDE eclipse is available for free and you can plug in most commonly used compilers, many of these as well available without charge.
