View app source code

Question

Is there any way or tool to show sourc code for any program while it's executing on windows ?
Thanks for you

Answer 1

Are you referring to .exe and .dll files?
What you are referring to is called reverse engineering and in case the code is not encrypted, then you will be able to view source code in some cases.
There are several third-party tools to do that.

Answer 2

For .NET applications, you can use tools like ILSpy to get an approaching source code
For Win32 executables (PE format), you cannot get the source code, you can just disassemble them (with tools like W32Dasm or others)

Answer 3

It depends on the underlying language that the developers used.

For Java and .NET languages it is possible most of the time to "de-compile" the source code. it's not going to be the true original code (variable names will be different, optimizations by the compiler will have rearranged code, etc) but it will be close.

Other languages such as C/C++ are not so easy.
