hey, it's nice to see one of my longstanding ERs finally getting reinvented... Seems just another case of that magic ER-rule "If sender-name = "woody" then delete" ;)

I'm impressed! Can't thank you enough! In fact one of my new apps under development, to be delivered at the end of 2004, hopefully sometime after VFP9 goes live, will require an online/offline connectivity detection scheme as it will be used in laptops on the field. It will greatly benefit from a seamless, more "natural" connectivity check. That same app also needs to detect a diskette. Now I can get rid of my old-cluncky method to see if a disk was (maybe) inserted.

Thank you MS. You guys in the VFP Team rock!

This is very cool. Is this going to be hooked to all top level windows or just the VFP desktop?

In the sample code Calvin worked up, _VFP and _SCREEN were referenced so I'm assuming that this will apply to all top level forms. Just an educated guess, though.

Really cool!

Another useful use cases:
- Hooking ActiveSynch to get synchronize Mobile DBs and apps.
- Launching processes during Screen-saver time (house-keeping stuff).
- Sensing wireless/net connection to send/receive data.
- Detecting arriving email?

Who knows! We will have to search the docs to see all the things we can do with this.

Thanks a lot!

Now if only you could reconnect a broken file handle in your error handler, this would make for some really robust systems! You can currently trap a 1104 error (caused by pulling out your network cable for instance) and with RegWinProc I assume we could detect when the network came back online again but nothing that I can find will reset the connection. If you know what table it is, you should be able to close and reopen it, but you can't do that in an error handler (what do you do if your in the middle of an SQL query for instance). "With great power, comes a whole new list of enhancement requests." ;)

Hey Rob, sorry but you're right - can't mend a broken file handle. But at least you'll be able to catch the break and attempt to mitigate.

"Make it so Number 1" this would be very very useful! Keep up the great work!

Wow! This tops even the new reportwriter features! Absolutely awesome!

Great feature, now we can use RegisterWindowMessage() to communicate between VFP applications or grab the MessageBox window and change the appearance of the child controls (prompts, icon etc).

Excellent function but will it work with non-visual COM servers??

Well, now it appears that it will be enhanced functionality with the existing BINDEVENTS function. Stay tuned.

Excellent new feature of VFP9. Does anybody know, if VFP9 supports callback-functions (e.g. RasDialFunc) too?
