WatchDirectory...for cashregister print

[cliv]

I have four computer conected in a network .... running a mini POS in VB6 ... but only one computer(Server) have a cashregister connected (serial port).
I need that other computer print to cashregister.
....
So i think the best ideea is to create a "Folder monitor" on Server and then send file from other computer from network to that folder.

I found a sample here :
http://www.mvps.org/vbvision/_sample...ctory_Demo.zip

The problem is that:
- I want to modify the sample so the event notification appear only when the file terminate to write on server monitor ( to avoid run cashregister exe application when file is incomplet write to disk....delay appear because of network transfer)
--------------------------------
1. File start to write in disk (BonFile) - NO EVENT
2. File Write (BonFile) - NO EVENT
3. File terminate write (BonFile) - EVENT NOTIFICATION -----> Run Cashregister EXE

4. Shell and wait for execute Cashregister EXE
5. Delete file (BonFile)

6. Loop
--------------------------------

Sorry for my english...
Hope understand me.
