39 In Visual C#.NET Using Barcode generation for .Four formats are uncompressed and three are compressed The first four entries in the table are for DIB files This well-known format is thoroughly documented in the MSDN Library and is the format that Visual Studio NET provides for creating bitmap images Notice hat the size of these images is the same for a given number of bits per pixel This reflects the fact that DIB files are uncompressed The last three formats are the compressed formats: GIF, PNG, and JPEG To make sense of these formats, we must discuss the contents of the three images The single-color image was a solid black rectangle Each of the three compressed formats easily beat any of the uncompressed formats for the single-color image The reason is that compressed formats look for a pattern and use that information to store details of the pattern A single color is a pretty easy pattern to recognize and compress The second column, the multicolor image with regular data, shows the results for an image created with a solid background and vertical stripes We used vertical stripes in an attempt to thwart the compression because run-length encoding of horizontal scan lines is an obvious type of compression We were surprised (and pleased) to find that PNG compression was able to see through the fog we so carefully created it created the smallest image in the table The third column, the multicolor image with irregular data, shows the sizes for images created with very random data For this test, we copied.Related: Printing Code 128 Java , Interleaved 2 of 5 Generator Java , Create QR Code ASP.NET

Anyone who has ever written a program knows that mistakes are inevitable Anyone who writes software professionally knows that producing good software requires a systematic approach to nding bugs By far the most widely used approach to bug nding is dynamic testing, which involves running the software and comparing its output against an expected result Advocates of extreme programming want to see a lot of small tests (unit tests) written by the programmer even before the code is written Large software organizations have big groups of dedicated QA engineers who are responsible for nothing other than writing tests, running tests, and evaluating test results If you ve always thought of security as just another facet of software quality, you might be surprised to learn that it is almost impossible to improve software security merely by improving quality assurance In practice, most software quality efforts are eared toward testing program functionality The purpose is to find the bugs that will affect the most users in the worst ways Functionality testing works well for making sure that typical users with typical needs will be happy, but it just won t work for finding security defects that aren t related to security features Most software testing is aimed at comparing the implementation to the requirements, and this approach is inadequate for finding security problems The software (the implementation) has a list of things it s supposed to do (the requirements) Imagine testing a piece of software by running down the list of requirements and making sure the implementation fulfills each one If the software fails to meet a particular requirement, you ve found a bug This works well for testing software functionality, even security functionality, but it will miss many security problems because security problems are often not violations of the requirements Instead, security problems are frequently unintended functionality that causes the program to be insecure Whittaker and Thomson describe it with the diagram in Figure 11 [Whittaker and Thompson, 2003].

You might think talking about QA this early in the book is putting the cart before the horse Well, you're wrong Quality assurance must e a thread that runs through your application from requirements capture, definition, and design, to implementation, and on to deployment The standard, at least for Web application development, tends to be "design, develop, test, deploy" You'll notice something peculiar about this methodology: If problems are found in testing (and they always are), no step to fix them is included before the deployment phase No wonder so much bad code is out there in the world! As humans venture into the universe, we're taking this poorly QAed code with us! A prime example of missing QA was the much-publicized loss of the NASA Mars Climate Orbiter spacecraft in 1999 It spun out of control because part of the software assumed English units and another part assumed metric units It's inconceivable that these code modules were never tested together, but there you go a half a billion bucks down the drain So what can you do to make sure you never lose a half a billion smackers It's actually not that difficult to avoid The tricky part is thinking about QA and testing at the beginning of the project and developing a comprehensive test plan along with your requirements documents and technical specifications The second tricky part is making sure that you've budgeted enough time and money for testing.

Overall project organization and people/roles involved (including who is responsible for the testing) Training needs for testers What do your testers need to know before they can adequately test the software Testing priorities and focus Make sure your testers don't get sidetracked testing a part of your application that isn't ready or isn't relevant Test outline: a full description of the test approach by test type, feature, functionality, process, system module, and so on and so forth Discussion of any specialized software or hardware tools that will be used (such as special testing tools) and in what capacity these are being used Test environment: hardware, operating systems, browser versions, other required software, and so on Problem tracking and resolution tools and processes How are you going to track problems found In many projects I've worked on, especially when dealing with a new development environment, we start by building a small bug-tracking application using the same tool with which we'll be building whatever we're building.
