Page 55 CHAPTER 4 Setting up Hardware and Software Microsoft Producer can interact with a variety of different hardware and software components. In order to interact with the various hardware and software components, you need to have installed or connected these devices properly. It can be intimidating to start the process of purchasing, installing, and connecting hardware such as a Web camera, video camera, VCR, or video capture card. The goal of this chapter is to ease some of the anxiety that can come with purchasing and installing the different hardware and software components you can use with Microsoft Producer. This chapter will also explain the differences between the various types of video cameras and capture devices that you can use with Microsoft Producer. Video Formats The first step when choosing a camera that will fit your video recording needs is to understand the different available video formats. The video camera s format refers to the way that the video signal from the camera is recorded to tape. Each video camera uses one format for recording. This section introduces and briefly explains the different types of video cameras on the market today. MiniDV A digital video (DV) camera that records in the MiniDV format is capable of producing high-quality professional video. When video is recorded in MiniDV format by a DV camera, there is very little distortion in the recorded video and audio, and the video is of higher resolution than most other video formats. This lack of distortion is because the camera records through a precise digital signal rather than an analog signal used by the other formats such as Standard 8, Hi 8, VHS, and S-VHS. A MiniDV camera is the highest-quality camera available for consumers on the market today. Because the video is recorded digitally, there is very little noticeable loss in quality when the video is transferred from MiniDV tape to a computer. The MiniDV format records video on 6-millimeter (mm) tape that is stored in a small cassette. These cassettes are smaller than those used by analog cameras. Today, a vast majority of the MiniDV cameras have a digital output that lets you connect your camera, through an Institute of Electrical and Electronics Engineers (IEEE) 1394 connection (often called FireWire or iLink), to a computer that has an IEEE 1394 card or port. When digital video is transferred through this connection, the video is recorded on

If the lock is Free: Set state to OwnedByReaders, RR=1, Return If the lock is OwnedByReaders: RR++, Return Else: RW++, Block reader thread . When the thread wakes, loop around and try again .

You can also specify the number of rows the sub-grid will span. You can automatically expand the rows to use the available space. If you select this option, the form will override the number of rows you specify and expand depending on the number of records in the view. This option is not available if the Show Chart Only option is selected in the Chart Options area.

the positive approach. Notice, though, that the negative solution gives you access to all the customer attributes, while the positive solution gives you access only to the customer IDs. To access other customer attributes, you need to add a join between the result set and the Customers table. When comparing the performance of the solutions in this case, the solution applying the positive approach performs better. In other cases, the negative approach might yield better performance. You now have another tool that you can use when solving problems.

In 17, the cgi library is covered in more depth, along with information about using HTTP cookies and sessions, so if this mode of deployment is of interest to you, please refer there for extended information and longer examples. In general, however, CGI execution is becoming unpopular due to its lack of speed and the need for a Ruby interpreter to be executed on every request. This makes CGI unsuitable for high-use or heavy-load situations.

In this exercise, you enable ICS on Computer1. This feature performs address transla tion for all computers on the network segment and enables them to communicate with Internet hosts. ICS also provides addresses for DHCP clients on the local segment and configures these clients to use the ICS computer as a DNS server. After ICS is enabled, the DNS server on the ICS server performs recursion to answer the DNS queries from local clients.

Figure 7-16. A CREATE SEQUENCE command syntax diagram A sequence definition may consist of a start value, increment value, minimum value, and maximum value. You can also specify whether the sequence generator should stop when reaching a boundary value, or CYCLE the sequence numbers within the minimum/maximum range. All sequence attributes are optional, as Figure 7-16 shows; they all have default values.

Tip The MSBuildExtensionsPath property resolves to %ProgramFiles%\MSBuild, which makes this an ideal directory to use for build agent installation of customizations. This directory is used by Team Build, Visual Studio, and third-party MSBuild extensions. To modify the customizations you would deploy your changes to each build agent. This method works well if you have a small number of build agents and a large number of build de nitions. It doesn t enforce the same rigor as the branch and merge method as it doesn t force the use of version control. You should still keep the master copy in version control and deploy changes from there to the build agents.
