When you access an Array field of a structure that is defined in .NET from inside a COM DLL, you may receive the following error message:
“An unhandled exception of type ‘System.ArgumentException’ occurred in ProjectName”

Because of the late-bound method that is used in this case, the Visual Basic 6.0 runtime cannot get the type information for the Array field that you are attempting to access.
Symptoms
When you use ASP.NET to create a new event source in the event log, you may receive the following error message:
System.Security.SecurityException: Requested registry access is not allowed.
Resolution
By default, the user token of the ASP.NET worker process is ASPNET (or NetworkService for applications that run on Internet Information Services [IIS] 6.0). The problem in the “Symptoms” section occurs because your account does not have the correct user rights to create an event source.
