Figure 12-7: The sample application displaying downloaded sales data in DataSet format. Accessing BinHex-Encoded Images Calling the GetSalesReportBarChart method is not all that different from calling the GetSalesReport method, but more work is needed to make the downloaded data usable. As mentioned, the GetSalesReportBarChart method draws a bar chart, converts it to JPEG, encodes the image as a BinHex string, and packs everything into an XML document. The content of the document is then returned as a string, as shown here: ServiceSalesProvider ssp = new ServiceSalesProvider(); string encImage = ssp.GetSalesReportBarChart(theYear); The next step is transforming the string into a bitmap and displaying it in the PictureBox control. The following procedure takes the BinHex image description and creates an equivalent Bitmap object. Because the string is an XML document, an XmlTextReader object is needed to parse the contents and then decode the BinHex data. private Bitmap EncodedXmlToBitmap(string encImage) { Bitmap bmp = null; // Parse the XML data using a string reader StringReader buf = new StringReader(encImage); XmlTextReader reader = new XmlTextReader(buf); reader.Read(); reader.MoveToContent(); // The root node of the document is <jpeg> if (reader.LocalName == "jpeg") { 450 vb.net wpf pdf viewer: PDF Clown – Open Source PDF Library for Java and .NET vb.net pdf viewer free NuGet Gallery | Spire.

Next you copy the resultant array of bytes into a temporary memory stream. This step is necessary because a Bitmap object can't be created directly from an array of bytes. Finally, the returned Bitmap object is bound to the PictureBox control in the form, as shown in the following code: PictureContainer.SizeMode = PictureBoxSizeMode.StretchImage; PictureContainer.Image = bmp; Figure 12-8 shows the results. = CreateEventW, PulseEvent, WaitForSingleObject, WaitForSingleObjectEx, WaitForMultipleObjects, WaitForMultipleObjectsEx, MsgWaitForMultipleObjects, MsgWaitForMultipleObjectsEx, SignalObjectAndWait CloseHandle, ExitProcess, GetProcAddress, LoadLibraryA, LoadLibraryW, LoadLibraryExA, LoadLibraryExW, FreeLibrary Figure 12-8: The sample application displaying an encoded bar chart.

Jul 7, 2018 · This Quick Tip shows you how to display a PDF with VB.NET. ... It's the same one you probably use to display PDF files anyway: the free Adobe Acrobat PDF Reader. To use the Reader control, first make sure that you have ... The previous two examples are in all probability much simpler than most code you will find in production, and creating a complete set of test cases for these code examples would be relatively quick work. For simple functions, calculation of cyclomatic complexity is straight- forward and easily performed manually. For large functions with many decision points, or for automatically calculating cyclomatic complexity across a large code base, many tools are available (including tools from McCabe such as McCabe IQ, [3] or free tools such as CCCC, NDepend, and Code Analyzer). For managed code development, several free tools are on the market that calculate the cyclomatic complexity of a given piece of code, including Sourcemonitor, Reflector, and FxCop. A primary use of cyclomatic complexity is as a measurement of the testability of a function. Table 7-1 contains McCabe's guidelines on using cyclomatic complexity. Table 7-1: Cyclomatic Complexity Risk Analysis Open table as spreadsheet Cyclomatic complexity Associated risk 1 10 11 20 21 50 50+ Simple program with little risk Moderate complexity and risk High complexity and risk Very high risk/untestable After pondering the problem of how to collect the information I needed to satisfy the first four requirements, I realized that I was going to have to intercept (or hook) the functions in Table 15-1 to record the acquisition and release of synchronization objects. Hooking functions isn't a trivial task, and I'll explain how I implemented the code in the section "Hooking Imported Functions" later in this chapter. The one constraint that hooking imported functions imposed on DeadlockDetection is that the code for DeadlockDetection must reside in a DLL because the hooks apply only to the address space in which they're 538 created This constraint means that the user must load the DeadlockDetection DLL into her address space, a requirement that isn't too harsh given the benefits As a DLL, the utility would integrate easily with a user program, requirement 7 specified in the list in the preceding section As you're looking over Table 15-1, you might have noticed that I didn't include certain potentially blocking message functions such as SendMessage, PostMessage, and WaitMessage Originally, I'd intended to include these functions, but when I ran Charles Petzold's canonical "Hello World!" GUI program under DeadlockDetection, DeadlockDetection reported so many calls that the program essentially fell over In the effort of keeping DeadlockDetection as lightweight as possible, I had to forego them Gathering the information to satisfy requirements 1 through 4 follows as a direct consequence of choosing the in-process function hooking approach. BinaryWriter writer = new BinaryWriter(fs); writer.Write(img); writer.Close(); Consider these values as guidelines. I have seen code with low cyclomatic complexity filled with bugs and code with cyclomatic complexity well over 50 that were well tested and contained few defects. This approach means that each of the multithreading and synchronization functions will be calling directly into the DeadlockDetection code with all the information I need Making DeadlockDetection as lightweight as possible (requirement 5) was a tough condition to satisfy I tried to code efficiently, but efficient code went only so far toward fulfilling the goal I set out to achieve Figuring that you know best what types of synchronization objects you're using in your program, I grouped the object types so that you can specify just those functions you want to hook For example, if you're concerned only about deadlock problems on mutexes, you can process only mutex functions To make DeadlockDetection even more useful, you can specify, on the fly, which sets of synchronization object functions you want to watch You can also turn DeadlockDetection on and off as many times as needed. When converting a Bitmap object to JPEG, you can control the compression ratio to obtain a better image. However, JPEG is not a compression scheme designed for text and simple figures like bar charts. In fact, JPEG was originally designed to effectively compress photographic images. To ensure a better image, you might want to use the GIF format or control the compression ratio of the final JPEG image. You can do that by using one of the overloads of the Bitmap object's Save method. You might even want to give your application an accelerator key or a special menu option that toggles the entire DeadlockDetection system Allowing this narrow scope meets requirement 5 and helps with requirement 7 The only requirement left is number 6: making the output processing as extensible as possible I wanted to give you the ability to slice and dice the output, rather than force you to make do with some arbitrary, hard-coded format By keeping the main hooking and processing separate from the output code, I can achieve greater code reuse because the only part being changed, the output side, is much easier to develop than the core side I named the output portions DeadlockDetection extensions, or DeadDetExt for short A DeadDetExt is simply a DLL that has several exported functions that DeadlockDetection looks for and calls when appropriate Now it's time to explain how to use DeadlockDetection. Halstead metrics are an entirely different complexity metric based on the following four measurements of syntax elements in a program: If you understand the requirements I set out and understand how to use this utility, you'll find it easier to see how I implemented it Using DeadlockDetection The first step in using DeadlockDetection is to put DEADLOCKDETECTIONDLL, its initialization file, and the appropriate DeadDetExt DLL in the same place The initialization file is a simple INI file that, at a minimum, must specify the name of the DeadDetExt file to load The following sample is a DEADLOCKDETECTIONINI file that loads the supplied TEXTFILEDDEXTDLL: [Initialization] ; The only mandatory value, the name of the DeadDetExt file that will ; handle the output 539. Using the System.Activator Class A remoting client can obtain a proxy to make calls to a remote object in two ways: by using the new operator or by using methods of the System.Activator class. The Activator class provides two methods CreateInstance and GetObject. Clients of wellknown objects use GetObject, whereas clients of client-activated objects use CreateInstance. GetObject returns a proxy for the well-known type served at the specified URL location, as shown in the following code. GetObject is a wrapper placed around the global RemotingServices.Connect method. The proxy is built on the client from the remote object metadata and exposed to the client application as the original type. ServiceSalesProvider ssp; ssp = (ServiceSalesProvider) Activator.GetObject( typeof(ServiceSalesProvider), "http://www.contoso.com/SalesReport"); From this relatively simple explanation, it should be clear that .NET Remoting is no less quirky than DCOM, but unlike DCOM, the .NET Framework successfully hides a great wealth of low-level details. CreateInstance differs from GetObject in that it actually creates a new remote instance of the object, as shown here: // Set the URL of the remote object object[1] attribs; attribs[0] = new Activation.UrlAttribute(url); // Create the instance of the object ServiceSalesProvider ssp; ssp = (ServiceSalesProvider) Activator.CreateInstance( typeof(ServiceSalesProvider), null, attribs); vb.net adobe pdf reader component how to open PDF file INSIDE VB .
