AspEventViewer Component

Here is the component you need to read the event log from either ASP scripts or any other Automation application (samples for ASP and MS Excel are supplied).

If you are long-time fan of our site, you may know about the EventLog ISAPI extension we were providing to read the event log entries online.

This ISAPI extension has been converted to a component that can be used in ASP scripts or for "normal" server information gathering from for example Microsoft Excel.

The AspEventViewer component sports all functionality you need to read all three different sources (System, Security and Application) on your local computer as well as any remote computer.

Additionally to the functionality of reading the event log, you can also use the component to delete the event log entries.

The API is limited to only a few functions (pseudo-code below):

bool OpenLog(machine, source)
bool CloseLog()
bool ClearLog(machine, source)
long GetFirst()
long GetNext(eventId, eventType, eventSource, eventDate)
bool GetRecord(nRecordNo, eventId, eventType, eventSource, eventDate , computername, accountname,error-description)

First of all, you have to open the event log (OpenLog), then you can access entries either via GetRecord (please notice that the accountname return value currently is not implemented!) or iterating over all entries using GetFirst() and GetNext().
