Vb.net create windows event log

The computer name specified in sourceData is not valid. The source name specified in sourceData is null. The log name specified in sourceData is not valid. The log name specified in sourceData is not valid for user log creation.

The source name specified in sourceData results in a registry key path longer than characters. The first 8 characters of the log name specified in sourceData are not unique. The source name specified in sourceData is already registered. The source name specified in sourceData matches an existing event log name. The following example determines whether the event source named SampleApplicationSource is registered on the local computer.

If the event source does not exist, the example sets the message resource file for the source and creates the new event source. Finally, the example sets the localized display name for the event log, using the resource identifier value in DisplayNameMsgId and the resource file path in messageFile.

The example uses the following message text file, built into the resource library EventLogMsgs. A message text file is the source from which the message resource file is created. The message text file defines the resource identifiers and text for the category, event message, and parameter insertion strings. Specifically, resource identifier is defined for the localized name of the event log.

Use this overload to configure a new source for writing entries to an event log on the local computer or a remote computer. It is not necessary to use this method to read from an event log. The CreateEventSource method uses the input sourceData Source , LogName and MachineName properties to create registry values on the target computer for the new source and its associated event log.

A new source name cannot match an existing source name or an existing event log name on the target computer. If the LogName property is not set, the source is registered for the Application event log. If the MachineName is not set, the source is registered on the local computer. To create an event source in Windows Vista and later or Windows Server , you must have administrative privileges.

The reason for this requirement is that all event logs, including security, must be searched to determine whether the event source is unique. Starting with Windows Vista, users do not have permission to access the security log; therefore, a SecurityException is thrown.

If you are a member of the Built-in Administrators group, you are assigned two run-time access tokens: a standard user access token and an administrator access token.

By default, you are in the standard user role. To execute the code that accesses the security log, you must first elevate your privileges from standard user to administrator. You can do this when you start an application by right-clicking the application icon and indicating that you want to run as an administrator. Use WriteEvent and WriteEntry to write events to an event log. You must specify an event source to write events; you must create and configure the event source before writing the first entry with the source.

Create the new event source during the installation of your application. This allows time for the operating system to refresh its list of registered event sources and their configuration. If the operating system has not refreshed its list of event sources, and you attempt to write an event with the new source, the write operation will fail. You must have administrative rights on the computer to create a new event source.

You can create an event source for an existing event log or a new event log. Top Rated Most Recent. Accept Solution Reject Solution. Copy Code. Posted Feb pm Abhinav S. Apparently you completed you typing faster then I did.

Abhinav S Feb am. You posted a longer answer. Hi Abhinav, Thanks for the quick reply. I tried the method you mentioned, however, it still create the log directly under "Application and Services Logs".. If you see in your Event viewer, you will see "Microsoft" folder under the "Application and Services Logs".

I wanted my event log to be like that.. Best regards, Paulus. Try to reboot the machine after creation of event log: there are situations when the system get messed up as a result of debug runs. Also, I don't remember exactly, I'm not sure Abhinav used correct parameter.

Try: EventLog. Please see all overloads of System. This is static approach. Non-static approach is creating an instance of EventLog and assign the event source permanently. If you still did not sort it out, I'll write instructions on usage later. Hi SA, Thanks for the reply. Rebooting my pc is not solving the problem either. Thank you.. Best Regards, Paulus. See my updated answer: added usage sample, works as intended!

Member 3-Nov pm. Hey did you got the solution for this? Abhinav, I thing you made a bug in usage. See above. Will you check up and fix it? Abhinav, I added usage sample to my Answer and tested it; it works.

You may want to test yours. Unfortunately I could not test this code. Perhaps will do so later. If your code works, the OP can use your code snippet anyway. Thank you. Nish Nishant Feb am. Voted 5. Abhinav S Feb pm. Thanks Nish. This is one of few questions where I've seen answer comments go into 2 pages. Did anyOne found the solution for this? I am facing the same problem. Do you mean Windows System Log? Yes, this is not so easy to understand. You need to install your own Event Source.

Now, open up the EventLogger. The class begins similarly to the ErrorLogger. Like the ErrorLogger. This function is pretty easy to follow; the arguments passed to the function are described in the commented section. The code checks to see if the application name exists in the error log, and if it does not, it adds it to the log.

Notice also that this method was defined as a function, and that it returns a Boolean which is set to True if it successfully writes to the log or to False if it does not; this will allow you to check the returned value to see if the operation were successful within your code. Having accomplished that, it populates the newly instantiated log entry with the entry information and event type, and adds the event to the log.

Executing this function will result in an addition to the log file that will look something like this:.
