The ECP tests are then derived from creating unions of valid class subsets until all valid class subsets have been used in a test, and then evaluating each invalid data subset individually This seems like a simple enough explanation; however, this technique requires both in-depth and broad knowledge to decompose input and/or output variable data precisely into discrete valid and invalid class subsets The subsets are defined in such a way that any element of a given subset would logically produce the same result as any other element in that subset We can then design both positive and negatives tests to systematically evaluate the functional capabilities of input and/or output parameters and the system's ability to handle any errors adequately The value of the ECP technique is twofold. vb.net read pdf to text: Reading PDF content with itextsharp dll in VB .

Include the following namespaces in the Program.cs file. the cardinal rule of assertions Of course, it logically follows that if developers aren't checking for null objects in their assertions, they aren't checking for them in their normal parameter checking Do yourself a huge favor and start checking objects for null The fact that NET applications don't have to worry about pointers and memory blocks means that at least 60 percent of the assertions we were used to handling in the C++ days just went away On the assertion front, the NET team added as part of the SystemDiagnostic namespace two objects, Debug and Trace, which are active only if you defined DEBUG or TRACE, respectively, when compiling your application Both of these defines can be specified as part of the project Property Pages dialog box As you've seen, the Assert method is the method handling assertions in NET. vb.net open pdf file in adobe reader: Manipulating PDF files with iTextSharp and VB .

NET . <platform> </platform> </platforms> To produce these results, I created the GetXmlFileNodeLayout function. This function scans the entire contents of the XML file and processes each node found along the way. Only two types of nodes are relevant for this example: the start and end tags of Element nodes. The NodeType enumeration identifies these two types of nodes through the keywords Element and EndElement. private string GetXmlFileNodeLayout(string file) { // Open the stream XmlTextReader reader = new XmlTextReader(file); // Loop through the nodes StringWriter writer = new StringWriter(); string tabPrefix = ""; while (reader.Read()) { // Write the start tag if (reader.NodeType == XmlNodeType.Element) { tabPrefix = new string('\t', reader.Depth); writer.WriteLine("{0}<{1}>", reader.Name); } else { // Write the end tag if (reader.NodeType == XmlNodeType.EndElement) { tabPrefix = new string('\t', reader.Depth); writer.WriteLine("{0}</{1}>", reader.Name); } } } // Write to the output window string buf = writer.ToString(); writer.Close(); // Close the stream 29 tabPrefix, tabPrefix, read pdf file using itextsharp vb.net Parsing PDF Files using iTextSharp (C#, .

NET Framework applications from NuGet.org. Include the following namespaces in the Program.cs file. First, it helps us systematically reduce the number of tests from all possible tests and still provides us with a high degree of confidence that other variables or variable combinations in the same subset will produce the same expected result repeatedly For example, assume you are testing a text box control that accepts a string variable of Unicode characters between upper case A and Z with a minimum string length of 1 and a maximum string length of 25 characters Exhaustive testing would include each letter one time (261) and each letter combination for every possible string length So, to test for all possible inputs the number of tests is equal to 2625 + 2624 + 2623 + 261 That is a really big number (RBN)! But let's make an assertion that testing the string "BCD" is similar to testing the string "WXY. Interestingly enough, both Debug and Trace have identical methods, including an Assert method I find it a little confusing to have two possible assertions that are conditionally compiled differently Consequently, since assertions should be active only in debug builds, I use only DebugAssert for assertions Doing so avoids surprises from end users calling me up and asking about a weird dialog box or message telling them something went bad I strongly suggest you do the same so that you contribute to some consistency in the world of assertions There are three overloaded Assert methods All three take a Boolean value as their first or only parameter, and if the value is false, the assertion is triggered As shown in the preceding examples in which I used DebugAssert, one of the methods takes a second parameter of type string, which is shown as a message in the output. The final overloaded Assert method takes a third parameter of type string, which provides even more information when the assertion triggers In my experience, the two-parameter approach is the easiest to use because I simply copy the condition checked in the first parameter and paste it in as a string Of course, now that the assertion requiring the conditional expression is in quotes, make it part of your code reviews to verify that the string value always matches the real condition The following code shows all three Assert methods in action: DebugAssert ( i > 3 ) DebugAssert ( i > 3 , "i > 3" ) DebugAssert parameter") ( i > 3 , "i > 3" , "This means I got a bad. reader.Close(); return buf; } The Boolean value that controls the main loop stops the loop when the reader's internal pointer reaches the end of the stream. GetXmlFileNodeLayout is designed to analyze all nodes but process only those of type Element or EndElement. The name of the node, formatted to look like a tag name, is output to a memory string as a line of text. After finding an Element or EndElement node, the function uses the reader's Depth property to get the nesting level of the current node and arranges a prefix string made of as many tab characters as the depth level. The prefix string is inserted into the output buffer before the node name to produce properly indented text. You might have noticed that the GetXmlFileNodeLayout function accumulates the text that represents the node layout into a StringWriter object. The StringWriter object is a typical .NET writer class and offers a more friendly programming interface than the classic String class. StringWriter lets you express the content in lines and automatically provides for newline characters. In addition, its writing methods support placeholders and a variable-length parameters list. GetXmlFileNodeLayout then uses the StringWriter object's ToString method to return the accumulated text as a plain string. Note The full source code for a Windows Forms application that uses the GetXmlFileNodeLayout function is available in this book's sample files. The application name is NodeLayout. " So, logical deduction of the valid class subsets for this specific parameter would include the following: The uppercase Unicode characters between uppercase A and Z A string of characters with a string length between 1 and 25 characters Based on this model of valid data for the sample input parameter, a string of "ABCDEF" should produce the same result as a string of "ZYXWVUTSRQPONM," and the same result for a string composed of "KUGVDSFHKIFSDFJKOLNBF" The second advantage of the ECP technique is that we can effectively increase the breadth of data coverage by randomly selecting elements from a given subset to use as test data because any element from a specific valid or invalid class subset should produce the same result (if the data is correctly decomposed into discrete subsets and there is no errant behavior) as any other element in that subset. The .NET Debug object is intriguing because you can see the output in multiple ways. The output for the Debug object and the Trace object for that matter goes through another object, named a TraceListener. Classes derived from TraceListener are added to the Debug object's Listener collection property. The beauty of the TraceListener approach is that each time an assertion fails, the Debug object runs through the Listener collection and calls each TraceListener object in turn. This convenient functionality means that even when new and improved ways of reporting assertions surface, you won't have to make major code changes to benefit from them. Even better, in the next section, I'll show you how you can add new TraceListener objects without changing your code at all, which makes for ultimate extensibility! The default TraceListener object, appropriately named DefaultTraceListener, sends the output to two different places, the most visible of which is the assertion message box shown in Figure 3-1. As you can see in the figure, the bulk of the message box is taken up with the stack walk and parameter types as well as the source and line for each item. The top lines of the message box report the string values you passed to Debug.Assert. In the case of Figure 3-1, I just passed "Debug.Assert assertion" as the second parameter to Debug.Assert. Reading and Converting Text To read the content of the reader's current node, you normally use the Value property. This property, however, always returns a string that you might need to convert to a more specific type such as a date or a double. To convert a string to a .NET Framework type, you should use any of the XmlConvert class methods. How is the XmlConvert class different from the System.Convert class the .NET Framework primary tool for converting from one type to another The two classes perform nearly identical tasks, but the XmlConvert class works according to the XSD data type specification and ignores the current locale. Let's look at an example that illustrates the difference between the two converting classes. Suppose that you have an XML fragment such as the following: <employee> <hired>2-8-2001</hired> <salary>150,000</salary> </employee> The current locale dictates that the hire date is February 8, 2001, and the yearly salary is $150,000. If you convert the strings to specific .NET types using the System.Convert class, all will work as expected. If you convert using XmlConvert, you'll get errors: // Assume the reader points to <hired> DateTime dt = XmlConvert.ToDateTime(reader.Value); // Move the reader to <salary> reader.Read(); double d = XmlConvert.ToDouble(reader.Value); 30 Using the previous example, tests for the given name parameter will surely include nominal real-world test data such as "Bob," "Nandu," "Elizabeth," or "Ling" But static test data provides very little value in terms of new information or evaluating the robustness of the algorithm after the first iteration (unless. read pdf file using itextsharp vb.net Reading PDF form fields using iTextSharp - Microsoft Dynamics ...
