how can i log events to myLog?

hello experts,

when i run "eventvwr.msc" i can see that i created a log called "MyLog".
now when i try to write logs to it , my logs are written to a log called "Application".


in order to write to my log i try the following code in the begining of my service.

 if(!EventLog.SourceExists("drains"))
                EventLog.CreateEventSource("drains", "MyLog");
            aDrainsLog_ = new EventLog();
            aDrainsLog_.Source = "drains";

i know that i could use a static method to write evetns.

what would be my test in order to check and then to write to it using the
static method.

any help is welcome.

thank ingfraga,

thank you for the links, i changed my methods and tested both,
static and instance,

you could try, calling win32 api, wich I really dont like, but here is it.
// DLL import for backing up an event log
[DllImport("advapi32.dll", SetLastError=true, CharSet=CharSet.Auto)]
static extern bool BackupEventLog(IntPtr hEventLog, string backupFile);
 
// DLL import for opening an event log
[DllImport("advapi32.dll", SetLastError=true, CharSet=CharSet.Auto)]
static extern IntPtr OpenEventLog(string lpUNCServerName, string lpSourceName);
// Build the back-up filename (full path)
string EventFile = string.Format("{0}\\Log-{1}-{2}-{3}-{4:T}.evt", Globals.RunningDirectory,DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, DateTime.Now);
// Open the log for backing up
IntPtr LogHandle = OpenEventLog(ProgramEventLog.MachineName, LogName);
// Backup the log to the specified filename
BackupEventLog(LogHandle, EventFile);

Open in new window

when i debug:
 
1.            if(!EventLog.SourceExists("drains"))
2.                EventLog.CreateEventSource("drains", "eplan_services");
3.            aDrainsLog_ = new EventLog("eplan_services","SHIRO-2", "drains");
4.            aDrainsLog_.Source = "drains";

line 2,  can see that aDrainsLog_ has Log = Application,
line 3 , "Log" change to eplan_service,  

but later in other methods, when writing to aDrainsLog_ it would write to Application event.
...i dont understand.

Look at this url.

Note: I am starting to think, that you cannot write logs if you are with the asp.net account, unless you give the privileges, this topic is really interesting, I will dig into it.
