exe to C++ source code

VC++ compiles the code into binary format which you never decompile like we are doing with .Net.

with .Net its entirely different topic.

the answer is BIG NO

read the discussion. it may help you.

By the way, you also have to ensure that it is legal to do so as it would generally not be the case for commercial software.

If it is not you that has written the original software, then except if it is explicilty written than you are allowed to reverse engineer the program, you should not doi so before asking the permission to the original author.

So in practice, you should only try it on your own code... but if it is your own code, then why not use the original code instead.

Anyway, you will never get code that somehow ressemble C++ code as much information is lost when the executable is produced.

As Phillipe Mori said: if you don't have explicit permission to do such a thing, it is most likely illegal. If you do have permission, then whoever gave you the permission normally should have no problem providing you with the source code.

Assuming that you do have the permission but not the source code (dog ate the hard disk and no backups?), the best you can hope for is "readable" Assembler, not C/C++. While it's technically possible to automatically convert Assembler code into C/C++, that wouldn't greatly increase readability. So, unless you can read and understand Assembler, that wouldn't be a great help.
