Computer programs contain thousands of decisions: If this happens, do that unless the other thing happened, then do this first. Programs that contain numerous choices or decisions have more potential to contain failures and are often more difficult to test. One of the most common methods of determining the number of decisions in a program is by using a measurement called cyclomatic complexity. Cyclomatic complexity is a measurement developed by Thomas McCabe [2] that identifies the number of linearly independent paths (or decisions) in a function. A function that contains no conditional operators (such as conditional statements, loops, or ternary operators) has only one linearly independent path through the program. Conditional statements add branches to the program flow and create additional paths through the function. Program maintenance becomes an issue when cyclomatic complexity numbers rise. Psychologists have demonstrated that the average person can hold only five to nine pieces of information in short-term memory at one time; thus, when the number of interrelated choices grows beyond five to nine there is a much higher potential for the programmer to make a mistake when modifying the code. Exceptionally high numbers of decisions can lead to code that is difficult to maintain and even more difficult to test. The most common method of computing McCabe's complexity measurement is by first creating a control flow graph based on the source code, and then calculating a result based on the graph. For example, consider the code in Listing 7-1.

What the team didn't know is that each process has something named a process critical section that the operating system uses to synchronize various actions happening behind the scenes in a process One situation in which the process critical section is used is to serialize the execution of DllMain for the four cases in which DllMain is called: DLL_PROCESS_ATTACH, DLL_THREAD_ATTACH, DLL_THREAD_DETACH, and 536. A client enabled to make remote calls on a remote object simply creates an instance of the desired class using the language-specific operator for instantiation new in C# and Visual Basic Alternatively, the client can use the SystemActivator object a managed counterpart of the VBScript CreateObject and GetObject functions.. vb.net read pdf to text: How to Extract Text from PDF Document in C#, VB .

DLL_PROCESS_DETACH The second parameter to DllMain indicates the reason the call to DllMain occurred In the team's application, the call to LoadLibrary caused the operating system to grab the process critical section so that the operating system could call the DLL's DllMain for the DLL_PROCESS_ATTACH case The DLL's DllMain function then spawned a second thread Whenever a process spawns a new thread, the operating system grabs the process critical section so that it can call the DllMain function of each loaded DLL for the DLL_THREAD_ATTACH case In this particular program, the second thread blocked because the first thread was holding the process critical section Unfortunately, the first thread then called WaitForSingleObject to ensure that the second thread was able to properly initialize some shared objects. int CycloSampleOne(int input) { int result; if (a < 10) result = 1; else result = 2; return result; } vb.net display pdf in picturebox Extract Text from PDF in C# (100% .NET) - CodeProject

i think the easiest way is to use the Adobe PDF reader COM Component ... form & modify the “src” Property to the PDF files you want to read. Writing the Client Component Figure 12-6 shows the initial user interface of the client application we'll use to query for sales reports and bar charts. You select the year of interest and click one of the two buttons Get Data to display sales information as a DataSet object, or Get Chart to display the information as a bar chart saved as a JPEG image. The form contains a DataGrid control (invisible by default) and a PictureBox control. Needless to say, the DataGrid object will display the contents of the DataSet object, whereas the PictureBox object will show the image. Because the second thread was blocked on the process critical section, held by the first thread, and the first thread blocked while waiting on the second thread, the result was the usual deadlock The Lesson The obvious lesson is to avoid doing any Wait* or EnterCriticalSection calls inside DllMain so that you avoid those kernel object blocks because the process critical section blocks any other thread As you can see, even experienced developers can get bitten by multithreaded bugs and as I mentioned earlier, this kind of bug is often in the place you least expect it DeadlockDetection Requirements As you might have noticed in the preceding tips and tricks section, I didn't provide very many suggestions about what to do when an unexpected deadlock paralyzes your code. This code is represented by the control flow graph shown in Figure 7-1. Most of the recommendations there were more preventive measures you can take to try to avoid deadlocks in the first place rather than prescriptions for fixing them when they do occur As you know, solving deadlocks with just the debugger isn't easy In this section, you'll get the additional help you need, in the DeadlockDetection utility Here's the list of basic requirements I worked with when I developed DeadlockDetection: 1 Show exactly where the deadlock happens in the user's code A tool that tells only that EnterCriticalSection is blocked doesn't help much To be really effective, the tool needs to let you get back to the address, and consequently the source file and line number, where the deadlock occurred so that you can fix it quickly 2 Show which synchronization object caused the deadlock 3 Show which Windows function is blocked and the parameters passed to the function. Figure 12-6: The sample application in action, waiting for user input. Accessing the Raw Data Once the remote assembly has been referenced by the project and the remote type configured in the form's Load event, you can write the client application and use the remote type as if it were a local type. The following code shows what happens when you click to get raw data: private void ButtonGetData_Click(object sender, System.EventArgs e) { // Get the year to process int theYear = Convert.ToInt32(Years.Text); // Instantiate the object and issue the call ServiceSalesProvider ssp = new ServiceSalesProvider(); DataSet ds = ssp.GetSalesReport(theYear); // Turn on and fill the DataGrid control // Also and turn off the picture box PictureContainer.Visible = false; Data.Visible = true; Data.DataSource = ds.Tables[0]; // Update the UI Title.Text = "Sales Report for "+ theYear.ToString(); 449 It helps to see timeout values and the values passed to the function 4 Determine which thread caused the deadlock 5 The utility must be lightweight so that it interferes with the user's program as little as possible 6 The information output processing must be extensible The information collected in a deadlock detection system can be processed in many ways, and the utility needs to allow others, not just you, to extend the information as they see fit 7 The tool must integrate easily with the user's programs One of the key points to keep in mind with a utility such as DeadlockDetection is that it definitely affects the behavior of the application it's observing Once again, it's the Heisenberg uncertainty principle in action DeadlockDetection can produce deadlocks in your programs you might not otherwise see because the work it does to gather information slows down your threads. Figure 7-1: Control flow diagram for the example of simple cyclomatic complexity in Listing 7-1. Based on the control flow graph, McCabe identifies the formula to calculate cyclomatic complexity for a function as edges - nodes + 2. In the graph in Figure 7-1, nodes appear as shapes, and the edges are the lines connecting the nodes that show potential paths through the program. The nodes in Figure 7-1 labeled A through D show the statements in the function. Using the formula described earlier, there are four nodes, and four edges, or paths between nodes. Analysis shows that the complexity of this function is 2 (edges (4) - nodes (4) + 2 = 2). An accurate shortcut to calculate cyclomatic complexity is simply to count the number of conditional (predicate) statements and add 1. In the preceding example, there is one condition (if (a < 10)), and thus the cyclomatic complexity is 2. The code sample in Listing 7-2 shows a slightly more complex (yet still relatively simple) example. The control flow graph in Figure 7-2 represents this code. I almost defined this behavior as a feature because any time you can cause a deadlock in your code, you've identified a bug, which is the first step toward 537. } The code in boldface demonstrates that, at this point, using the remote object is in no way different from using any other local, or system, class. Figure 12-7 shows the sales information displayed in DataSet format. correcting it and as always, it's better for you to find the bugs than for your customers to find them. High-Level Design Issues with DeadlockDetection I had to figure out how to implement DeadlockDetection given the preceding requirements. I first needed to determine which functions I needed to monitor so that I could report the complete deadlock trace. Table 15-1 lists all the functions, grouped by type, that I decided I needed to monitor to implement DeadlockDetection.
