how os identify different types of executable files
How operating system identify different types of executable files
i have two .exe files one is developed in java code and another one is developed in c# code
how my operating system knows which exe belongs to which language ?
|

The OS does not know about the used programming language for executable files.
Please read also the text on top of this page.

. Technical discussions are welcome, but if you need specific programming question answered please use Quick Answers[^] To me, this is more of a technical discussion than a specific programming question and is very valid for the Lounge.
There are two kinds of people in the world: those who can extrapolate from incomplete data.
There are only 10 types of people in the world, those who understand binary and those who don't.

It doesn't know; it doesn't care.
Once the code is written, it is compiled into a "lower level" language - either Native code (which is a binary form that the processor chip understands directly) or an intermediate language that a secondary system convert to native code as it runs. Both Java and C# compile to an intermediate language (this is IL for C# and JVM for Java) and the .NET framework CLR module uses a "Just In Time - or JIT - compiler to convert that to native code to be executed. In the case of Java it is either compiled in a similar manner of interpreted by the Java runtime as it is executed.
The system doesn't care: the startup code your your app runs the relevant runtime module to process your code invisibly and that runs your application.

Which is why they asked. Give them a break.

Come on! I want some fun!
By the way- my problem is not with the question asked here - except QA, there is no a better place... My problem is with the question itself as it smells of ignorance... One who really wants to understand these things can do a lot of research (and find the books one has to read), before coming here to ask a questions, that the true answer is book long...

I agree. But why can't some of that research be asking and talking with those who already know (i.e. coming here and asking)?
I don't know about you but I started out knowing nothing. I wasn't born knowing. But yes, I started learning before the internet and had to do a lot more work to learn. There is value in that.

I think that there is huge value in doing your own research. finding the books, and actually reading them is irreplaceable, that's the reason I do not answer such 'question' like it was valid... not because this is The Lounge, but because it is me...

32bit .NET exes look pretty simple, they have an entry point that does
jmp [0x402000]
Which is where _CorExeMain is imported from mscoree.dll, so that's probably what "does the .NET thing".
I couldn't quickly figure out 64bit .NET exes, their entry point is 0 but that would execute the MZ header.. some other magic is going on there.

It is true that you! can figure out from the EXE from which language it was compiled and even on what compiler and OS, but all that irrelevant to the OS, running your EXE... It cares no, just load and run it... If it has a JMP at the beginning or a NOP it is up to them...

Well that was my point, the OS doesn't have to figure out anything, a 32bit .NET program starts as a native program which itself, by taking that jump, starts up the .NET stuff.

It is a Q&A question.
Answer: Files have an extension which is a hint how the OS how to interpret some header information in the file.

It's a cartoon strip. But ... do not, at work, search for it: it is frequently VVNSFWAT1 and should probably not be read by anyone without a mind broad enough to be tied in a bow under your chin.
Can be very funny - but is nearly always very rude.
