14 Aug 2018 ... Use the following code snippet to read an existing PDF file . If, for example, a customer reported that certain characters in a specific font "looked funny," I could quickly examine the rendered font and determine the cause of the issue I also needed to verify that all characters in a font could draw without causing a problem In those days, in a few obscure cases an application would crash if it attempted to draw a particular character, or ranges of characters would have printing problems Testing printing of every character in every font certainly isn't good for saving time (or trees), but it was important to be able to spot-check new fonts and to investigate bugs reported by customers To help myself out in this scenario, I wrote a tool capable of displaying or printing all characters in a font with any selection of sizes and attributes (bold, italic, and so forth), as shown in Figure 10-2.. vb.net pdf read: VB Helper: HowTo: Open a PDF file in an Adobe Reader control ... vb.net pdf read Convert a pdf file into byte - CodeProject

As we'll see in later chapters, the various debuggers you have at your disposal have strengths and weaknesses depending on particular debugging situations Nothing is worse than having the wrong debugger pop up when you really want the one you know will simplify solving that bug you've spent weeks trying to duplicate This was a problem begging to be solved, so I set out to do so However, because of what look like bugs in the way JIT debugging starts under Visual Studio NET, I had to work through a lot of trial and error to get my approach working Before I can discuss the problems, I need to show you how Debugger Chooser, or DBGCHOOSER for short, works.

Hi all, When I open and read the pdf file everything looks fine, but ... 0 Dim line As StringBuilder = New StringBuilder() ' Read PDF file's text ... The idea behind DBGCHOOSER is that it acts as a shim program that gets called when the debuggee crashes and passes on to the real debugger the information necessary to debug the application To set up DBGCHOOSER, first copy it to a directory on your computer where it won't be accidentally deleted The operating system tries to start the debugger executable specified in the Debugger value of the AeDebug key, so if the debugger isn't available, you won't get any chance to debug the crash To initialize DBGCHOOSER, simply run it Figure 4-1 shows the configuration dialog box in which you set the appropriate commands for each of the various debuggers supported by DBGCHOOSER The initial run of DBGCHOOSER is set with the appropriate defaults for most developer machines If you don't have the various debuggers in the path, you can specify the appropriate paths. vb.net itextsharp pdfreader How to read PDF file using iTextSharp in ASP.

I'm calling a web service that is returning a pdf as a byte array. ... stuck with writing it to a file and then calling whatever PDF reader is installed ... Figure 10-2: Font display tool. The tool took only a few hours to write, but the first time I used it, I found a crash when "scrolling" through the characters in a third-party font. The other team members and I used this tool often throughout the development cycle for quick verification, smoke testing, and other investigations. We found only a few other bugs using the tool, but it was extremely beneficial in helping us verify a variety of font rendering issues. It wasn't an automated test, but it saved dozens of hours of time among several engineers. Pay special attention to the Visual Studio NET debugger path because the JIT shell used by Visual Studio NET isn't in the path by default After you click OK in the configuration dialog box, DBGCHOOSER writes your debugger setting to an INI file stored in your Windows directory and sets itself as the default debugger in the AeDebug key of the registry.. Creating XML documents in a programmatic way has never been a particularly complicated issue. You simply concatenate a few strings into a buffer and then flush the buffer to a storage medium when you have finished. The process is quick, easy, and straightforward could you ask for more Well, actually, you should! XML documents are text-based files, but they also contain a lot of markup text, and as you know, dealing with markup text can at times be boring or even annoying. More than just being a bother, you might find that supplying the necessary quotation marks and angle brackets can make your code more error-prone. Creating XML documents programmatically by simply putting one string of text after another is effective as long as you can absolutely guarantee that subtle errors will never sneak into the code mainstream, which is not much different from certifying that all of your manually created code is 100 percent bug-free. The Microsoft .NET Framework provides a more productive, and even elegant, approach to writing XML code. Based on ad hoc tools, this approach simply applies the same pattern that has been the key to XML's rapid adoption focus on the data and ignore the rest. Enter XML writers. Figure 4-1: The DBGCHOOSER configuration dialog box After you experience what I hope is one of your rare crashes, you'll see the actual chooser dialog box pop up when you click Debug in the crash dialog boxes, as shown in Figure 4-2. Simply select the debugger you want to use and start debugging. Stobie and Mark Bergman, "How to Automate Testing: The Big Picture," March 1992, http://keithstobie.net/Documents/TestAuto_The_BigPict.PDF. that do not expect values larger than 232 will "roll over" (or overflow) to the minimum value of the data type. In this case, it means that the number after 4294967295 is zero. The value of 232 is 4294967296. Because counting on computers starts at zero, the range of an unsigned 32-bit integer is from 0 to 4294967295. An XML writer represents a component that provides a fast, forward-only way of outputting XML data to streams or files. More important, an XML writer guarantees by design that all the XML data it produces conforms to the W3C XML 1.0 and Namespace recommendations. Suppose you have to render in XML the contents of a string array. The following code normally fits the bill: void CreateXmlFile(String[] theArray, string filename) { StringBuilder sb = new StringBuilder(""); // Loop through the array and build the file sb.Append("<array>"); foreach(string s in theArray) { sb.Append("<element value=\""); sb.Append(s); sb.Append("\"/>"); } sb.Append("</array>"); // Create the file StreamWriter sw = new StreamWriter(filename); 111 Figure 4-2: The DBGCHOOSER debugger chooser dialog box The implementation of DBGCHOOSER is nothing exciting. The first point of interest is that when I called CreateProcess on the debugger the user chose, I had to ensure that I set the inherit handles flag to TRUE. To ensure everything is copacetic with the handles, I have DBGCHOOSER wait on the spawned debugger until it ends. That way I know any necessary inherited handles are still there for the debugger. Although it was more of a pain to figure out than interesting to implement, getting Visual Studio .NET to work properly from DBGCHOOSER took some doing. Everything worked like a champ with WinDBG, Microsoft Visual C++ 6, and Dr. Watson. However, when I'd start Visual Studio .NET (actually VS7JIT.EXE, which in turn spawns the Visual Studio .NET debugger), a message box would pop up indicating that JIT debugging was disabled and wouldn't start debugging. At first I was a little stumped about what was going on, but a quick check with the wonderful registry monitor program (Regmon), from Mark Russinovich and Bryce Cogswell at www.sysinternals.com, showed me that VS7JIT.EXE was checking the AeDebug key's Debugger value to see whether it was set as the JIT debugger. If it wasn't, up popped the JIT debugging disabled message box. I was able to verify that this was the case by stopping DBGCHOOSER in the debugger while DBGCHOOSER was active because of a crash, and changing the Debugger key back so that it pointed to VS7JIT.EXE. I have no 145 idea why VS7JITEXE feels it's so important that it won't debug unless the debugger is the JIT debugger I did a little quick coding in DBGCHOOSER to fake out VS7JITEXE by changing the Debugger value to VS7JITEXE before I spawned it, and all was good with the world To get DBGCHOOSEREXE reset as the JIT debugger, I spawned a thread that waits for 5 seconds and resets the Debugger value As I mentioned when I first started talking about DBGCHOOSER, my solution isn't perfect because of problems with JIT debugging in Visual Studio NET On Windows XP, I was testing all permutations of starting and running Visual Studio NET and found that VS7JITEXE stopped running After playing with it a bit, I found that two instances of VS7JITEXE actually run when starting Visual Studio NET as the JIT debugger. A wide variety of approaches and solutions for test automation is used at Microsoft. Not all teams approach automation or test case generation in terms of SEARCH, but an approach that considers automating each stage of the testing effort is prevalent on most teams. sw.Write(sb.ToString()); sw.Close(); } The output is shown in Figure 4-1.
