Test Broadly BVTs should cover the product broadly. They definitely should not cover every nook Not Deeply and cranny, but should touch on every significant bit of functionality. They do not (and should not) cover a broad set of inputs or configurations, and should focus as much as possible on covering the primary usage scenarios for key functionality. Debuggable and In a perfect world, BVTs would never fail. But if and when they do fail, it is Maintainable imperative that the underlying error can be isolated as soon as possible. The turnaround time from finding the failure to implementing a fix for the cause of the failure must be as quick as possible. The test code for BVTs needs to be some of the most debuggable and maintainable code in the entire product to be most effective. Good BVTs are self-diagnosing and often list the exact cause of error in their output. Great BVTs couple this with an automatic source control lookup that identifies the code change with the highest probability of causing the error. Trustworthy You must be able to trust your BVTs. If the BVTs pass, the build must be suitable for testing, and if the BVTs fail, it should indicate a serious problem. Any compromises on the meaning of pass or fail for BVTs also compromises the trust the team has in these tests. vb.net open pdf file in adobe reader: Open pdf file in Adobe reader created in code-behind - Stack Overflow vb.net pdf read [Solved] itextsharp read pdf file - CodeProject

Xml assembly, which ensures the effective working of factory methods The following pseudocode shows the internal architecture of a factory method: public virtual XmlXXX CreateXXX( params ) { return new XmlXXX ( params ); } Note When the node class is XmlDocument, the methods WriteTo and WriteContentTo happen to produce the same output, although they definitely run different code WriteTo is designed to persist the entire contents of the node, including the markup for the node, attributes, and children WriteContentTo, on the other hand, walks its way through the collection of child nodes and persists the contents of each using WriteTo Here's the pseudocode: void WriteContentTo(XmlWriter w) { foreach(XmlNode n in this) nWriteTo(w); } A Document node is a kind of super root node, so the loop on all child nodes begins with the actual root node of the XML document. vb.net print pdf to specific printer: PLEASE explain to me by VB . net code how to print a given path PDF ... visual basic read pdf Parsing PDF Files using iTextSharp (C#, .

Let's assume a user sends me a completed PDF Form . Can I use VB . NET ... There is an ActiveX interface to Acrobat/ Reader called the Interapplication Interface. all allocations out of a source file, and on a specific line in a source file In addition, you can have the MemStress extension prompt you with a message box on each allocation asking whether you want this particular allocation to fail, and you can also set the DCRT library flags you'd like in effect for your program The MemStressDemo program is a sample MFC program (that comes with this book's sample files) that allows you to experiment with setting different options from the MemStress user interface (UI) and see the results It also serves as the unit test for MemStress itself Using the MemStress extension is relatively simple In your code, include BUGSLAYERUTILH and call the MEMSTRESSINIT macro with the name of your program To stop the memory allocation hooking, use the MEMSTRESSTERMINATE macro. BVT attribute Explanation Critical Your best, most reliable, and most trustworthy testers and developers create most reliable and most trustworthy BVTs. Good BVTs are not easy to write and require time and careful thought to adequately satisfy the other criteria in this table. vb.net pdf reader control Parsing PDF Files using iTextSharp (C#, .

Read the pdf Documents line by line and search the data then fetch the data. You can start and stop the hook as many times as you want when running your program After you've compiled your program, start the MemStress UI, click the Add Program button, and type the same name that you specified in the MEMSTRESSINIT macro After you've selected the failure options you want, click the Save Program Settings button to save the settings into MEMSTRESSINI Now you can run your program and see how it behaves when it fails memory allocations You'll probably want to be very selective about using the MemStress extension For example, if you specify that you want all allocations over 100 bytes to fail and you have the MEMSTRESSINIT macro in your MFC application's InitInstance function, you'll likely take down MFC because it will be unable to initialize. In this case, WriteTo simply writes out the entire contents of the document but the super root node has no markup As a result, the two methods produce the same output for the XmlDocument class Events of the XmlDocument Class Table 5-3 lists the events that the XmlDocument class fires under the following specific conditions: when the value of a node (any node) is being edited, and when a node is being inserted into or removed from the document Table 5-3: Events of the XmlDocument Class Events Description NodeChanging, The Value property of a node belonging to this document is about to be changed or has been NodeChanged changed already NodeInserting, A node is about to be inserted into another node NodeInserted 175. You'll have the best results with the MemStress extension if you limit its use to key areas in your code so that you can test them in isolation Most of the implementation of MemStress is in the reading and processing of the MEMSTRESSINI file, in which all the settings for individual programs are stored From the DCRT library perspective, the important function is the call to _CrtSetAllocHook during the MemStress initialization because this call sets the hook function, AllocationHook, as the allocation hook If the allocation hook function returns TRUE, the allocation request is allowed to continue By returning FALSE, the allocation hook can have the DCRT library fail the allocation request. An example of a BVT suite for a simple text editor such as Windows Notepad could include the following: 1 Create a text file 2 Write some text 3 Verify basic functionality such as cut, copy, and paste work 4 Test file operations such as save, open, and delete A daily (or more frequent) build and BVT process reduces the chance of errors caused by large integrations or sweeping changes Keeping the product in a state where it will build and where it will run every day is critical to a healthy software organization Test teams at Microsoft have the same need for daily builds as product teams For this reason, source code for automated tests and test tools are also built daily, typically as part of the same process used to build the product code. Table 5-3: Events of the XmlDocument Class Events Description in this document or has been inserted already The event fires whether you are inserting a new node, duplicating an existing node, or importing a node from another document NodeRemoving, A node belonging to this document is about to be NodeRemoved removed from the document or has been removed from its parent already All these events require the same delegate for the event handler, as follows: public delegate void XmlNodeChangedEventHandler( object sender, XmlNodeChangedEventArgs e ); The XmlNodeChangedEventArgs structure contains the event data The structure has four interesting fields: Action Contains a value indicating what type of change is occurring on the node Allowable values, listed in the XmlNodeChangedAction enumeration type, are Insert, Remove, and Change NewParent Returns an XmlNode object representing the new parent of the node once the operation is complete. The allocation hook has only one hard requirement from the DCRT library: if the type of block, as specified by the nBlockUse parameter, is marked as a _CRT_BLOCK, the hook function must return TRUE to allow the allocation to take place The allocation hook gets called on every type of allocation function The different types, as specified in the first parameter to the hook, are _HOOK_ALLOC, _HOOK_REALLOC, and _HOOK_FREE In my AllocationHook function, if the type is _HOOK_FREE, I skip all the code that determines whether the memory request should pass or fail For _HOOK_ALLOC and _HOOK_REALLOC types, my AllocationHook function performs a series of if statements to determine whether any of the failure conditions are met If a failure condition is met, I return FALSE Interesting Stress Problems Everything worked great in MemStress on my initial console sample program, and I was feeling fine. As I finished off the MFC-based MemStressDemo program, I noticed a compelling problem If I elected to have MemStress ask me with a message box whether I wanted allocations to fail, I would hear a series of beeps and MemStressDemo would stop working I was able to duplicate the problem every time and to duplicate the serious stress the problem was causing me because I didn't see what the issue could be After a few runs, I finally got a message box to show up Instead of being in the center of the screen, the message box was down in the lower right-hand corner When message 645. Breaking the Build The most minimum effect of a daily build is ensuring that compilation errors (also known as build errors) are caught within 24 hours of check-in Compilation errors are rare but can stop the engineering flow if the test team is waiting for the daily build to begin testing The most common reason for a compilation error is also the most preventable: syntax errors by the developer Anyone who has ever compiled any code or run a script has made a syntax error A missing semicolon, a mistyped keyword, or an errant keystroke can cause an error when the program is compiled or when the script is run These sorts of errors are inevitable, but they only cause a problem if the broken code is checked into source control I don't know any programmers who deliberately check in broken code, but some still make these mistakes through carelessness. vb.net pdfreader Adobe PDF Reader Control | Adobe Community - Adobe Forums
