As I was getting close to finishing around 500 lines of code, Jeff Prosise innocently asked if I had seen the is operator, which determines whether a run-time type of an object is compatible with a given type Developing my own is operator functionality was an interesting exercise, but it wasn't something I needed to do Once I had the Page object, I started looking for an AssertControl on the page I knew it could be embedded inside another control, so I used a little recursion to walk through everything Of course, when doing recursion, I needed to ensure I had a degenerative case or I could have easily ended up in an infinite recursion case For ASPTraceListenerFindAssertControl, I chose to take advantage of the very interesting out keyword, which allows you to pass a method parameter by reference but doesn't require you to initialize it. vb.net pdf text extract: How to Convert PDF to Text in .

Using GDI+ to Create Charts GDI+ is the latest incarnation of the classic Windows Graphical Device Interface (GDI), a graphics subsystem that enables you to write device-independent applications The NET Framework encapsulates the full spectrum of GDI+ functionalities in quite a few managed classes that wrap any GDI+ low-level functions, thus making them available to Web Forms and Windows Forms applications GDI+ services fall into three broad categories: 2-D vector graphics, imaging, and typography The 2-D vector graphics category includes drawing primitives such as lines, curves, and any other figures that are specified by a set of points on a coordinate system The imaging category includes functions for displaying, manipulating, and saving pictures as bitmaps and metafiles The typography category concerns the display of text in a variety of fonts, sizes, and styles Only the imaging functions are key to the GetSalesReportBarChart implementation. 0 0 1 0 0 vb.net pdf read: how to read PDF file using vb .

It's more logical to treat the condition not found as null, and the out keyword lets me do that The final work I do with an assertion in the ASPTraceListenerHandleOutput method is determine whether I'm supposed to pop into the debugger when an assertion is triggered The wonderful SystemDiagnosticsDebugger object allows you to communicate with a debugger from inside your code If a debugger is currently debugging the code, the DebuggerIsAttached property will be true and you can simply call DebuggerBreak to force a breakpoint stop in the debugger This solution assumes, of 85. itextsharp read pdf line by line vb.net How to read PDF file using iTextSharp in ASP.

You can't read and parse the contents of a PDF using iTextSharp like ... an existing PDF file using iText, you can only ' read ' it page per page. course, that you're actively debugging that particular Web site I still need to handle the case of getting a debugger cranked up when you're not debugging If you look at the Debugger class, you'll see it has a very cool method named Launch that allows you to start a debugger to attach to your process However, if the user account the process is running under isn't in the Debugger Users group, DebuggerLaunch doesn't work If you want to attach the debugger from the assertion code when you're not running under a debugger, you're going to have to get the account ASPNET runs under in the Debugger Users group Before I go on, I need to say that by allowing ASPNET to spawn the debugger, you are potentially opening security holes, so you'll want to enable this only on development machines that aren't directly connected to the Internet. In GDI+, the Graphics class represents the managed counterpart of the Win32 GDI device context You can think of it as the central console from which you call all primitives Everything you draw, or fill, through a Graphics object acts on a particular canvas Typical drawing surfaces are the window background (including control backgrounds), the printer, and in-memory bitmaps The following code creates a new bitmap object and gets a Graphics object from it: Bitmap bmp = new Bitmap(500, 400); Graphics g = GraphicsFromImage(bmp); gClear(ColorIvory); From this point on, any drawing methods called on the Graphics object will result in changes to the bitmap For example, the Clear method clears the bitmap's background using the specified color Creating a bar chart is as easy as creating and filling a certain number of rectangles, as shown in the following code. This is just a simple example to explain the principles of basis path testing and how to methodically analyze a function. Some people will look at the CountC function and focus on the poor quality of the code. For example, they ask why we are even checking for the character B or realize the variable k does absolutely nothing. Interestingly enough, we sometimes see things such as this in production code. The conditional clause could be for future use or a feature that was removed. The k variable is an example of dead code. Sometimes people focus on the poorly written code, but a professional tester can take even the most convoluted function and design structural tests for it. Of course, both of these errors might have been found during behavioral testing. But the dead code could not be detected by behavioral or exploratory testing from the user interface (and that is an error of commission) and if the error of counting the letter B is found, the tester has no way of determining which of the more than 100,000 other Unicode characters might also be incrementing the return value. So, which of the more than 100,000 Unicode characters do you choose Would you try them all Or perhaps would structural testing reduce the number of tests, increase efficiency, improve test coverage, provide more qualified information, identify different types of errors and help us understand why they occur, and potentially help reduce overall risk The IsValidMod10Number function is another great example of how basis path testing provides greater sensitivity to control flow as compared to block and decision testing in a real-world example. IsValidMod10Number.cs On Windows 2000 and Windows XP, ASPNET runs under the ASPNET account, so that's what you'll add to the Debugger Users group Once you've added the account, you'll need to restart IIS so that DebuggerLaunch will bring up the Just-In-Time (JIT) Debugging dialog For Windows Server 2003, ASPNET runs under the NETWORK SERVICE account After you add NETWORK SERVICE to Debugger Users, you'll need to restart the machine Once I got DebuggerLaunch working by getting the security correct, I had to ensure that I wasn't going to be calling DebuggerLaunch only under the right conditions If I called Debugger. Launch when no one was logged in on the server, I was going to cause lots of problems because the JIT debugger could be waiting for a key press on a window station no one could get to! In the ASPTraceListener class, I need to make sure the HTTP request is from the local machine because that indicates someone is logged in and there to debug the assertion The ASPTraceListenerIsRequestFromLocalMachine method checks to see whether either the host address is 127001 or the LOCAL_ADDR server variable is equal to the user's host address One final comment I have to make about bringing up the debugger involves Terminal Services If you have a Remote Desktop Connection window open to a server, the Web address for any requests to the server will resolve as an IP address on the server, as you would expect. We need to create a bar for each employee in the DataTable object and give it a height that is both proportional to the maximum value to draw and based on the scale given by the bitmap's size // Save the names of the fields to use to get data string fieldLabel, fieldValue; fieldLabel = dtColumns[0]ColumnName; fieldValue = dtColumns[1]ColumnName; // For each employee.. for(int i=0; i<dtRowsCount; i++) 434. // This function takes a string input, converts it to a number array, and applies a // mathematical formula to check the number's ability to meet the criteria for a valid // Mod 10 number and returns a Boolean result. A0 public static bool IsValidMod10Number (string number) { int[] numberArray = new int[number.Length]; bool checkBit = false; int sumTotal = 0; A1 for (int i = 0; i < number.Length; i++) { numberArray[i] = int.Parse(number.Substring(i, 1)); } My assertion code's default property, if the requesting address comes from the same machine as the server, is to call DebuggerLaunch As I was testing an ASPNET application by using Remote Desktop and running the browser on the server, I was in for a rude shock when an assertion triggered (Keep in mind that I was not debugging the process on any machine) While I expected to see either the security warning message box or the JIT Debugger dialog box, all I saw was a hung browser I was quite perplexed until I walked over to the server and moved the mouse There on the server's logon screen was my security message box! It dawned on me that although it looked like a bug, it was explainable As it is the ASPNET/NETWORK SERVICE account that brings up the message box or JIT Debugger dialog box, ASP. { // // Set up some internal variables to determine // size and position of the bar and the // companion text // // Draw the value (top of the bar) gDrawString(dtRows[i][fieldValue]ToString(), fnt, textBrush, x, yCaption); // Draw the bar Rectangle bar = new Rectangle(x, yBarTop, barWidth - 10, barHeight); LinearGradientBrush fill = new LinearGradientBrush(bar, ColorSpringGreen, ColorYellow, LinearGradientModeBackwardDiagonal); gFillRectangle(fill, bar); fillDispose(); // Draw the employee name (bottom of the bar) gDrawString(dtRows[i][fieldLabel]ToString(), fnt, textBrush, x, barBottom + textHeight); } At the end of the loop, the bar chart is completely rendered in the Bitmap object The bitmap is still held in memory in an intermediate, internal format, however Two more steps are necessary: converting the bitmap to a public format such JPEG, BMP, or GIF, and figuring out a way to persist or transfer its content. vb.net itextsharp pdfreader Using ItextSharp to read PDF fillable form values using C# | The ...
