How can I see the source code of an executable compiled by Delphi or C++?
Please help me.
After Edit:
I have a program. When I start this program, it shows a dialog and asks for a password. This password is saved in source code. I want to take this password quickly and easily.
You can't.
An enormous amount of information is thrown away when the compiler reduces human readable text source code down to machine executable code. Local variables don't need names in machine code, for example, they're just register bits in the instruction opcode.
This is why debugging a compiled executable to step through the original source files line by line can only be done if you have the compiler debug symbols to go with the executable.
There are utilities that attempt to reverse engineer machine code into source code, but the result is less readable to humans than the original machine code, in my opinion. Machine generated function names, machine generated local variables and arguments, and many times the utility has to guess as to the exact data types of arguments and local vars. (is this arg a signed int or an unsigned int? Hard to tell when it's just a stack slot or machine register)
Compiling to an intermediate representation, as is done in Java and .NET, provides for much more reversibility because the types and symbol names of much of the original code are retained. Reflector, for example, can emit C# source code that is very close to the original human written source code.
