Αν βγάλεις την δήλωση εκτός της function και την κάνεις public ίσως? (Δεν ξέρω C++, ξέρω C#)

[kickeras]

mipws na dilwnes to watcher i to

FileSystemWatcher* watcher[]=new FileSystemWatcher*[5]; eksw apo to function?

to public de tha kanei tpt pistevw

[vagpap]

Δεν χρειάζεται μόλις την δηλώσεις να την κάνεις και άμεσα object. Instantiation μπορείς κανονικά να την κάνεις στο Click που θες, απλά θα μπορούν να την δουν και οι άλλες fumctions
