Get an EventLog's sources

Question

Hi experts,

I'm using System.Diagnostics.EventLog to log some events in an application and its setup.

For an application, I think hard-coded event protocol and source names are OK.

Since windows xp's integrated event viewer shows new events only after the user told him, I wrote an event viewer as well, which makes events show up on creation.

Now I'd like to have this viewer a little generalized. Therefore hard-coded event protocol and source names ar no longer an option. Users could type in protocol and source names, introducing the risk of typing non-existent protocol and source names. Therefore I would like the user to choose protocol and source each from a dropdown containing valid names only.

There is a possibility to get all available protocols through EventLog.GetEventLogs() but I couldn't find one for sources.

Is there a method to get all active sources (for a protocol or in general)?

Here logs(0) is Appliacation logs. You can check your entries first.

VB

Dim logs() As EventLog = EventLog.GetEventLogs()
Dim logsE As EventLogEntryCollection = logs(0).Entries()
ComboBox1.DataSource = (From log As EventLogEntry In logsE Order By log.Source Select log.Source).Distinct.ToArray
