ASP.NET 4 in VB 2010 : Logging Exceptions (part 3) - Custom Logs, A Custom Logging Class

You can also log errors to a custom log. For example, you could create a log with your company name and add records to it for all your ASP.NET applications. You might even want to create an individual log for a particularly large application and use the Source property of each entry to indicate the page (or web service method) that caused the problem.

ASP.NET 4 in VB 2010 : Logging Exceptions (part 2) - Writing to the Event Log

There's a potential problem with this example. Ordinarily, Windows won't allow you to access the event log, and you'll get an exception when you attempt to run this example. The proper way to solve this problem depends on whether you're testing your web application or deploying it to a live web server.

ASP.NET 4 in VB 2010 : Logging Exceptions (part 1) - Viewing the Windows Event Logs

You can increase the log size, but you really shouldn't disable automatic log deletion altogether, because you could end up consuming a huge amount of space over time if information isn't being regularly removed.

Sharepoint 2010 : The Search User Interface - The People Search Page (part 3) - Expertise Search, The Preferences Page

SharePoint has one final and extremely interesting feature in SharePoint 2010 People Search. Users now have the ability to execute an expertise search for themselves with a special set of content. Expertise search, which is more commonly refered to as “vanity search,” is similar to “googling yourself.”

Sharepoint 2010 : The Search User Interface - The People Search Page (part 2) - Using People Search Results, Taking Action on Results

On a default People search page, below the name and contact information of a person, there are three links. These links allow the user to take action on the result. The first available action is the Add to My Colleagues link.

Sharepoint 2010 : The Search User Interface - The People Search Page (part 1) - People Search Options

Similar to the All Sites search page, navigating the the People search tab provides a few options not available by default from the query box. These include a link to the Preferences page and a link to open the search options.

Sharepoint 2010 : The Search User Interface - The Advanced Search Page (part 2) - Picking Property Restrictions

Some of the examples of property restrictions found in the previous section on search query syntax can be found in the following screens. Figure 5 provides an example of utilizing the author property with the equals and OR operators.

Sharepoint 2010 : The Search User Interface - The Advanced Search Page (part 1) - Keywords on the Advanced Search Page

The two categories of query manipulation are aligned with search syntax discussed in the last section. The first, “Find documents that have…”, is where the keywords for the query are entered.

Sharepoint 2010 : The Search User Interface - Search Query Syntax - Property Restrictions

In addition to Boolean operators, wildcards, and other syntax operators, SharePoint 2010 users can execute queries based on property restrictions to narrow the scope of a search.

Sharepoint 2010 : The Search User Interface - Search Query Syntax - Search Query Operators

The wildcard operator can be used at the end of a keyword query or property query to enable prefix matching. This allows a user to broaden a search by entering the initial portion of a search query and indicating that SharePoint's search engine should fill in the remainder of the query.

Sharepoint 2010 : Creating a Workflow Using SharePoint Designer

We’ve covered creating workflows using Visio 2010 with SharePoint Designer and Visual Studio 2010. For this simple workflow, we’ll make use of SharePoint Designer on its own and then export the workflow to Visual Studio to add some custom code.

Sharepoint 2010 : Creating a Workflow Using Visual Studio 2010 - Using the Visual Studio Workflow Designer (part 2)

Moving onto the setState1 activity, we can see that the CorrelationToken property is invalid. CorrelationTokens are an important aspect of WF workflows and are used to determine the scope of the activity.

Sharepoint 2010 : Creating a Workflow Using Visual Studio 2010 - Using the Visual Studio Workflow Designer (part 1)

When the workflow has been added to the project, the workflow designer tool will be displayed. You can see that its user interface is similar to the one we created earlier using Visio 2010. You can drag workflow activities from the toolbox on to the design surface to build up the workflow logic.

Sharepoint 2010 : Creating a Pluggable Workflow Service (part 6) - Calling a SharePoint-Hosted WCF Service

To complete our calculation engine implementation, we need to add some code to our DemoCalculationEngine project. We need a method that can make a call into our SharePoint WCF service to notify the workflow that calculation is complete

Sharepoint 2010 : Creating a Pluggable Workflow Service (part 5) - Calling a WCF Service, Receiving WCF Messages , Raising Events in a Workflow Service, Configuring Pluggable Workflow Services

When a service reference is added to a project, Visual Studio automatically stores the binding and endpoint configuration in either app.config or web.config, depending on the type of project. In our case, the configuration has been added to app.config even though this file is not utilized by the SharePoint deployment mechanism.

Sharepoint 2010 : Creating a Pluggable Workflow Service (part 4) - Using the ExternalDataExchange Attribute, Deriving from SPWorkflowExternalDataExchangeService

Notice a few things about this code sample. Firstly, the ExternalDataExchange attribute is used to let the workflow runtime know that the interface should be accessible to workflow activities.

ASP.NET 4 : Error Handling, Logging, and Tracing - Throwing Your Own Exceptions

You can also define your own exception objects to represent custom error conditions. All you need to do is create an instance of the appropriate exception class and then use the Throw statement.

ASP.NET 4 : Error Handling, Logging, and Tracing - Handling Exceptions

When an exception is thrown, .NET tries to find a matching Catch statement in the current method. If the code isn't in a local structured exception block or if none of the Catch statements matches the exception, .NET will move up the call stack one level at a time, searching for active exception handlers.

ASP.NET 4 : Error Handling, Logging, and Tracing - Exception Handling

Most .NET languages support structured exception handling. Essentially, when an error occurs in your application, the .NET Framework creates an exception object that represents the problem.
