Every .exe I make is incompatable with windows

[Lingrah]

So this may be a noob question, but every time I create an .exe (I use notepad...) it gives me this message

So I try taking a working .exe on my computer, change it to a txt, open it, type a letter anywhere, remove it (so it is the exact same as before) and save, it then proceeds to give me the message!  So my question would be, how do I save/edit a .exe so it works?

That's not how EXE files work. They need to be compiled using a compiler like Visual Studio or whatever they're calling it.

I think you want to create a .bat or .cmd file instead. Are you creating a command-line script?

I did end up creating what I originally wanted as a .cmd, but I am still curios how I get an .exe to work.

If you want to edit binaries (for whatever reason), use a hex editor and not a text editor.

By using a compiler.

You need to learn a language such as C# or C++ (there are many more out there), then use a program such as Visual Studio to code, build & compile your program into a .exe file that the processor can natively understand. EXE files cannot be edited in a text program. Highly skilled people (game modders etc) are able to decompile EXE files, but it is a long trial-and-error process.

 

It's probably better to stick to .bat/.cmd files. If you're making a small program it's not worth the effort trying to make an .exe out of it.

[You_are_a_cunt]

executable files are created using compilers.

 

most you can do in notepad is create .bat files that use the command prompt commands with some logic functions (see an example here: http://linustechtips.com/main/topic/463597-wip-the-lazy-mans-all-in-one-batch-file-v002 )

You are essentially violating the sensitive stucture of .exe. All executable file types comply to some standard structure. Windows uses the Portable Executable format, it has multiple file extensions available than just exe. This format is the only one in windows (besides COM which is simple but ancient and obslete anyways), ELF is a standard on Linux (it has no actual file extension), well you get the idea I hope. They contain code and data compiled from some language by a compiler, the result is unreadable, but as mentioned you can disassemble it to some language (commonly just Assembly language, because compilers do optimizations and the original language disassembly will be nor readable nor equivalent to what you compiled from). You need to learn coding if you want to make such programs, you can in theory make a new one with a hex editor (like HxD), but that is unreasonably difficult and pointless, you can learn Assembly, it's as close to machine code as you can reasonably get, but it's no child's play to learn, you need to study computer architecture thoroughly. I suggest you learn the C language if you are interested in this stuff.

 

A quick google search and I found a little read if you're interested. If you unfamiliar with any low-level coding prepare to have your brain f****d. https://en.wikibooks.org/wiki/X86_Disassembly/Windows_Executable_Files

 

This is a bit advanced, so I get if you don't understand anything, if so just start coding instead and read this sometime in the future.
