Create and Delete Custom Event Logs




Create the Custom Log

Use the CreateEventSource method to create your own custom event handler.
Before you create the event log, use the SourceExists method to verify that the source you are using does not already exist, and then call CreateEventSource.
If you try to create an event log that already exists, a System.ArgumentException error is thrown. 

The following code example demonstrates how to create a custom log: 

      ' Check if the log already exist
      If Not EventLog.SourceExists("MyOldSource", System.Environment.MachineName) Then
         ' Creating a new log
         EventLog.CreateEventSource("MyOldSource", "MyNewLog", System.Environment.MachineName)
         Console.WriteLine("New event log created successfully.")
      End If



You Can Write Event logs on Button Click Event

--------EXAMPLE-----------------


Private Sub btnWriteEntry_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnWriteEntry.Click

        'Write an entry to the Application Log. Notice the use of "DemoEventLog", this is the source that will be used
        'for this application and is used to state what application/service the log refers too.
        Dim elLog As New System.Diagnostics.EventLog("Application", Environment.MachineName, "DemoEventLog")

        elLog.WriteEntry("This is a information message", EventLogEntryType.Information)
        elLog.WriteEntry("This is a warning message", EventLogEntryType.Warning)
        elLog.WriteEntry("This is a Error message", EventLogEntryType.Error)
        elLog.WriteEntry("This is a Success Audit message", EventLogEntryType.SuccessAudit)
        elLog.WriteEntry("This is a Failed Audit message", EventLogEntryType.FailureAudit)

        elLog.Dispose()

    End Sub

SaveSetting and GetSetting in C#

How to use SaveSetting() and GetSetting() methods of VB in C#? Lets see, SaveSetting() method is used to store UI input data and GetSetting() method is used to retrieve that stored data. //Save textbox1's value SaveSetting (App.EXEName, "textboxes", "textbox1", textbox1.Text) //Get textbox1's value textbox1.text = GetSetting (App.EXEName, "textboxes", "textbox1", "") SaveSetting stores the data in the Registry (in HKEY_CURRENT_USER|Software|VB and VBA Program Settings|YourAppName).
