The property will be set to null if the node is being removed If the node is an attribute, the property returns the node to which the attribute refers Node Returns an XmlNode object that denotes the node that is being added, removed, or changed Can't be set to null OldParent Returns an XmlNode object representing the parent of the node before the operation began Returns null if the node has no parent for example, when you add a new node Some of the actions you can take on an XML DOM are compound actions consisting of several steps, each of which could raise its own event For example, be prepared to handle several events when you set the InnerXml property In this case, multiple nodes could be created and appended, resulting in as many NodeInserting/NodeInserted pairs. itextsharp read pdf fields vb.net: How to read PDF file in C#, VB .

I was a little stumped about how I got in there, but a comment in the code indicated that _AfxActivationWndProc is used to handle activation and make gray dialog boxes MFC uses a computer-based training (CBT) hook to catch window creations in the process space When a new window is created in my case, a simple message box MFC subclasses the window with its own window procedure When I understood all the issues, my personal stress level really shot up because I wasn't sure how to handle the situation Because the reentrancy was on the same thread, I couldn't use a synchronization object such as a semaphore because that would have deadlocked the thread After contemplating the problem a bit, I concluded that what I needed was a recursion flag that told me when AllocationHook was being reentered but it had to be on a per-thread basis. vb.net read pdf content Embed PDF into a VB .

In some cases, the XmlNode class's AppendChild method might fire a pair of NodeRemoving / NodeRemoved events prior to actually proceeding with the insertion By design, to ensure XML well-formedness, AppendChild checks whether the node you are adding already exists in the document If it does, the existing node is first removed to avoid identical nodes in the same subtree The XmlNode Base Class When you work with XML DOM parsers, you mainly use the XmlDocument class The XmlDocument class, however, derives from a base class, XmlNode, which provides all the core functions to navigate and create nodes XmlNode is the abstract parent class of a handful of node-related classes that are available in the NET Framework Figure 5-2 shows the hierarchy of node classes.. Usually it's "just a little change" that the developer forgets to double check by recompiling the local source code A simple prevention method could be to require developers to build before checking in source code, but this might be difficult to enforce, and some mistakes could potentially still slip through You Broke the Build! Throughout the software industry, there has been a long tradition of punishing those who break the build by making them wear a silly hat, putting a sign on their office door, making them buy donuts for the entire team, or otherwise calling attention to their mistake. I already had a critical section protecting against multiple-thread reentrancy in AllocationHook When I stated the problem this way, I realized that all I needed was a variable in thread local storage that I would access at the beginning of AllocationHook If the value was greater than 0, AllocationHook was being reentered as part of the MessageBox processing and I just needed to bail out of the function I implemented a quick dynamic thread local storage solution and my anxiety dropped considerably because everything started working as planned I thought I had everything rolling at this point, but I noticed my second stress problem When testing the code to fail on a specific source and line, the source filename was coming in as NULL and the source line was 0. Because I was using MFC for the MemStressDemo program, I thought it would have done the right thing and properly used the CRTDBGH versions of the allocation functions to pass in the source and line Alas, that wasn't the case I figured that all I needed to do was to drop in a define of _CRTDBG_MAP_ALLOC at the top of STDAFXH and include CRTDBGH as the end of the file Of course, as soon as I compiled, the spew of redefine and unexpected constant errors overwhelmed me No matter what I tried, I could not make an MFC application compile and use the proper version of the allocation functions After a while I found that the only thing I could reasonably do was extract the defines from CRTDBGH and include them manually in STDAFXH You can look at the MemStressDemo's STDAFX. Figure 5-2: Graphical representation of the hierarchy of node classes and their relationships in the .NET Framework. 177 I've known teams that called developers at home in the middle of the night to announce that they broke the build and need to come in pronto! This process can work in cases where people just need to be a bit more careful and think about what they are doing before they check in code, but sometimes people just make honest mistakes Fortunately, many teams are beginning to realize that humans do make mistakes, and that some build breaks are inevitable Instead of focusing on the punishment, these teams choose to do what they can to prevent any build breaks that do happen from adversely affecting the team Build breaks are often caused by reasons other than syntax errors "Forgetting to check in a file" is one. H to see exactly what you need to do Operating System Heaps Although you thought I might be done with the heap system after so many pages, there's another set of heaps you'll definitely want to know about the operating system heaps As an application starts under a debugger, Windows turns on the operating system heap checking This heap isn't the C run-time library debug heap; it's the Windows heap code for 646. Both XmlLinkedNode and XmlCharacterData are abstract classes that provide basic functionality for more specialized types of nodes. Linked nodes are nodes that you might find as constituent elements of an XML document just linked to a preceding or a following node. Character data nodes, on the other hand, are nodes that contain and manipulate only text. Properties of the XmlNode Class Table 5-4 lists the properties of the XmlNode class that derived classes can override if necessary. For example, not all node types support attributes and not all have child nodes or siblings. For situations such as this, the overridden properties can simply return null or the empty string. By design, all node types must provide a concrete implementation for each property. those heaps created with the HeapCreate API function The C run-time library heap is a separate entity Because processes use the operating system heaps extensively, for example, to do ANSI to Unicode string conversion when using ANSI functions, you might see information related to operating system heaps in your normal operation, which is why it's important to cover them here If you attach a debugger to your application rather than start your application under the debugger, you won't activate the operating system heap checking One of the most common questions I get is: "My application runs fine outside the debugger, but when it runs under the debugger, it has a User breakpoint exception Why won't my application run " The answer is the operating system heap checking. of the most common reasons I have seen that triggers a build break. When working with large, complex systems, it is also quite common to see build errors caused by a dependency changing in another part of the system. Think of the core Windows SDK header files (the files containing definitions of Windows data types and functions). A small change to one of these files can often cause build errors in farreaching components. On a smaller scale, changing an interface name in a COM library or other shared components can just as easily cause compilation errors in dependent components. Testing with Compilation On large platforms such as Windows, Windows CE, and Office, the test code frequently uses the available exported functions more than the supported applications. When I was on the Windows CE team, our daily build process would build the operating system, and then build all of our tests. From time to time, the compilation of our test code would cause a break (compilation error) because of a change to a function prototype or definition. It's hard to be happy about build breaks, but it was nice to catch these bugs long before a customer would have a chance to do so. Having the test code built at the same time as the product code enabled us to find these bugs. itextsharp read pdf fields vb.net VB Helper: HowTo: Open a PDF file in an Adobe Reader control ...
