I have an EDB server running. and an EDB client app attached to it. After leaving the client app open a long -a night- time (form with a grid on it) I want to edit some data, but the app freezes. What can cause this, and what can I do to overcome this (an how to reconnnect again)? EDB 1.05.1 Regards, Harry |

Edit the session configuration, either in EDB Manager or via code, to enable pinging. It is on the "Remote" tab in the EDB Manager on the lower portion of the tab, entitled "Connection Parameters". -- Regards, Jan Ferguson Harry de Boer wrote: <<LS << <<I have an EDB server running. and an EDB client app attached to it. <<After leaving the client app open a long -a night- time (form with a <<grid on it) I want to edit some data, but the app freezes.

I already did that, but it didnot solve it. Regards, Harry "J. B.

<< I already did that, but it didnot solve it. >> Does your application handle the TEDBSession.OnRemoteReconnect event ? If not, then that is likely the culprit. However, if you pinging enabled, then it shouldn't be required if the PingInterval is less than the session timeout setting on the EDB Server. -- Tim Young Elevate Software www.elevatesoft.com |

"Harry de Boer" | Tim,
I don't use the TEDBSession.OnRemoteReconnect event. The Pinginterval is less then the session timeout (default settings) and it's enabled, so indeed I thought I did not need it. For testing purposes (I do not know now what's happening other then that the app is freezing) what event could I use to see what's going wrong and how to code this event so that an error shows in a messagebox?

If not, then is the network connection subject to drop-outs (wireless) or IP address changes from a DHCP server ? -- Tim Young Elevate Software www.elevatesoft.com |

"Harry de Boer" | Tim,
I was testing on both a remote site, and a client/server on one machine. In both cases it went wrong. I will test again tomorrow, and try to figure out what is causing the problem.

"Harry de Boer" | Tim,
I've been testing it again and it seems that when a user's pc (client side) is in 'sleeping mode', longer then the timeout, this appears. Then -when not not in sleeping mode anymore-, on browsing (or changing a filter- a filter was active in this case) the app freezes. How to handle such a scenario. This ofcourse happens a lot (coffeebreaks, lunchbreaks etc). Is there a way to reconnect in these cases (so that a user does not notice it)?

The issue is that the sleep mode appears to be shutting down the thread that does the pinging in EDB. -- Tim Young Elevate Software www.elevatesoft.com |
