    What language are you using? Do you have syntax highlighting turned on? How are you trying to run the program? How does it fail to run? Please add some of these needed details to your question.

  • What program are you trying to run? If Notepad++ fails to run, how do you know about the issue with highlighting?

If you wondering why it's not showing coding errors, Notepad++ is a text editor, not an IDE. It's not designed to show errors as you type. If you want such a thing, try an IDE such as Eclipse.

  • So which purpose it is use?? Mar 14, 2014 at 20:36
  • It is purely for editing code. The highlighting will help but other than that it is down to you to know what you're doing.

  • Highlighting code makes it easier to read.

  • Syntax highlighting should be on automatically if you use the correct file extension. If it's not for some reason, it's in the language menu.
