Locking files

How can I lock files so that other programs cannot access them while mine does?

Use the open statement to lock:

Code:

---

Open filename For append lock read write As #1

Thanks Jim - I read your earlier posting with this in it but it did not seem to stop Adobe from opening a PDF locked this way (which was my aim).
