If you encounter a problem completing an exercise, you can find the completed projects in the samples installed from this book s companion CD. For more information about the project files and other content on the CD, see Using the Companion Media in this book s Introduction.

I'll suggest a couple of solutions to the problem of maintaining a custom sequencing mechanism. I'll show both synchronous and asynchronous solutions.

The image can be changed in many different ways using the Picture Tools (see Figure 12-17) . This also allows you to view the results of the excellent formatting capabilities of Excel 2007 in older PowerPoint versions .

The XmlTextReader class provides support for accessing attributes as independent nodes, allowing attribute information to be accessed using the XmlTextReader class properties described earlier in this section. If the current node has attributes, the XmlTextReader.MoveToFirstAttribute method returns true and moves the cursor to the first attribute of the current node; the first attribute becomes the current node. If the current node has no attributes, the method returns false and the cursor remains unmoved. Once the cursor is positioned on an attribute node, calling MoveToNextAttribute will move it to the next attribute node. If another attribute exists, the method will return true; otherwise, the method returns false and the position of the cursor remains unchanged. If the current node is not an attribute, but a node with attributes, the MoveToNextAttribute method has the same effect as MoveToFirstAttribute. The MoveToAttribute method provides three overloads for moving the cursor directly to a specific attribute node. These overloads are summarized in Table 11-10.
