70-562 Health Monitoring


Programmatic access to trace output from System.Web.TraceContext, using the TraceFinished event.

TraceContextRecord encapsulates a trace message, it can be put in CAtegory, ErrorInfo gets an exception, IsWarning indicates if it's a warning.

One has to attach en avent heandler to the Trace.TraceFinihsed += new TraceContextEventHandler(ONTraceFinished);

This handler recieves within it's event args a collection TraceContextRecord.

It can be used to log events on a sql server database.

First requires to run Aspnet_regsql.exe utility to create the db that will be used by listeners, Confiure SQL server for application Services, pick an instance to host on, you get a summary, and it will take care of confuring the database, now it's set to save health info on this db.

In the web.config, a healthMonitoring element needs to be added within the system.web eleement, by specifiying the provider, it's type, connection string, and then rules for which events to log, and EventMappings from the root Web.config file.

React JS Patterns

React JS is always evolving, and evolving quickly. These evolutions can be very significant ones, for example, the addition of hooks. React has a lot of code patterns, often these patterns are motivated by the DRY and/or the open-close principle. These patterns sometimes come in to replace a previous one, yet the previous ones still stays in use, as a consequence, the list of patterns keep growing. The goal of the next few posts will be to list the patterns commonly used in React JS developpement. Some patterns are more specific to JSX and I will start with these, and maybe add patterns specific to Redux.

70-562 Coding Web Parts

Coding Web Parts. The Web Part framework helps you write code to control all aspects of web parts behavior. Not all things are automaticaly handled, changing the display mode, changing the personalizing scope, reseting data, creating web parts with custom or user controls, and creating connections. PersonlizationADministration.FindSharedState method allows to find the personlization data using the FindUserState and ResetUser state. Web parts can be implement following those typical patterns, Master/Details(one shows the order, the other the items), Filter by Form(one shows the order, other allows to edit items, List/Form InputDisplay: one to edit, the other to view A web part can be a data provider, or consumer, or both. When using provider/consumer, The data is not guaranteed to be final until the prerender event. Custom controls as web parts allow to add new verbs to web parts, like, Verify. Specifying whether a control is a provider or cusumer is done in the cla...
