| Summary | 0002970: JvNTEventLog hangs if OnChange is assigned | ||||
| Description | If you use the JvNTEventLog with the OnChange event assigned, your application will hang when the component is destroyed. This is caused by the call WaitForSingleObject where the event handle is not being signaled on destruction. | ||||
| Additional Information | Recommended changes. Create a destructor TNotifyChangeEventLog destructor that will call SetEvent(FEventHandle) and alter the DoChange (or Execute) so that the event handler is NOT called when the thread is Terminated is true. | ||||
| Tags | No tags attached. | ||||

I've assigned the OnChange event (no code inside it) to the JVNTEventLog object from the demo provided with JVCL 3.00 and the application is closing down just fine. Could you try it yourself? Could you also post a sample application that reproduces the bug? |
|
|
May be something on my end. I received "Access violation at address 7800AE32 in module 'RPCRT4.dll'. Read of address 008E8000." When trying to run the EventViewer demo. |

|
The AV is in 0002889 and I can't do anything about that, the API function behaves very weirdly. |
|
|
Code has been reviewed and reworked a bit to avoid locking up infinitely. This will be in CVS as soon as the server is back. |
