How can you open a file with the program associated with its file extension?

Question

Is there a simple way to open a file by its associated program in windows? (like double clicking it in windows explorer but done automatically with my code)

For exam

Answer 1

If lpFile specifies a document file, the flag is simply passed to the associated application

So you need to substitute "c:\\windows\\notepad.exe" with the actual file you want to open and leave lpParameters null.
