The custom extension tag is added in Silverlight 5, which inherits fromMarkupextensionClass, reload the providevalue method in this class to determine the corresponding return value, to set the property of the bound control.
Next we will use the simplest example to understand how the custom extension tag works.
Step 1: Create a usermarkextension. CS class. Note that usermark (extension Tag Name) + extension. CS (fixed suffix) = usermarkextension.

The first four articles in Series 5 are based on the development of draw2d version 2.3.0.
Currently (2013/05), the latest version of draw2d is version 2.6.1.
The tooltip function is not provided in version 2.3.0, but the tooltip implementation method is provided in version 2.6.1.
Tooltip in version 2.6.1
Before we can see the source code, we thought that the implementation method should be to add a tooltip attribute to the shape in draw2d. JS
Outofmemoryexception is very likely to occur when computing requires a lot of memory space.
System. runtime. memoryfailpoint provides the memory check function before running computation that requires large memory.
When calling this method, perform the following steps (if you do not fully determine the size of the required memory, you can pass an approximate value)

JDBC 5 data source and data pool (web basic learning note 11), jdbc 5I. Why are data sources and connection pools used?
Currently, the developed applications are basically data-based and require frequent database connection. If each operation is connected to the database and then disabled, the performance will be limited. Therefore, we must find a way to reuseDatabase connection. In view of this situation, the concept of data source and connection poo
