As you can see, if you're not careful with tracing, your end users will be looking at them, which is always a little scary since developers are notorious for trace statements that could be career limiting if the output fell into the wrong hands Luckily, setting localOnly to true keeps the trace viewing only on the local server, even when accessing the trace log through the traceaxd HTTP handler To view your application trace logs, you'll simply have to use the greatest piece of software known to humankind, Terminal Services, so that you can access the server directly from your office and don't even have to get up from your desk You'll want to update the customErrors section of WEBCONFIG so that you have a defaultRedirect page, preventing your end users from seeing the ASPNET "Server Error in 'AppName' Application" error if they try to access trace. vb.net pdfreader: How to read PDF file using iTextSharp in ASP.

In the section "Validating Against an XSD Document," on page 130, we'll examine in more detail what happens when an instance of the XmlValidatingReader class is called to process an XML schema. vb.net read pdf line by line How to read PDF file in C#, VB .

ASPTraceListener is also used as the sole TraceListener for the SystemDiagnosticTrace object, so I redirect all traces to the TraceContextTrace so that they show up in the same place Tracing in Native C++ Applications Nearly all native tracing is done with a C++ macro traditionally named TRACE and is active only in debug builds Eventually, the function called by the TRACE macro will call the Windows API OutputDebugString so that you can see the trace either in the debugger or in DebugView Keep in mind that calling OutputDebugString causes a kernel mode transition That's no big deal in debug builds, but it can have a negative impact on performance in a release build, so be aware of any calls you might have floating around in your release builds. There was no object model for the application, and no other testability features, but given the simplicity of the. Creating an XML Schema with Visual Studio .NET Visual Studio .NET provides a visual editor, the XML Editor for XSD files. Instead of handling yourself the intricacies of schema markup, you can simply edit XML files using the drag and drop features and shortcut menus provided by the editor. Figure 3-9 shows the XSD file from the previous section as it appears in the Visual Studio editor. The figure shows the components of the XSD file: a global element of type AddressType and the corresponding definition of the global element's complex type. In fact, when the Windows team was looking for ways to speed up the performance of Windows as a whole, they removed numerous traces we all used to rely on, such as the DLL load conflict message that occurred on a DLL load, and it contributed to a very nice performance boost If you don't have a TRACE macro, you can use the one I provide as part of BugslayerUtilDLL All the actual work takes place in the DiagOutputA/W functions in DIAGASSERTCPP The advantage to my code is that you can call SetDiagOutputFile and pass in a file handle as the parameter and record all tracing to a file In addition to providing the TRACE macro, 18 covers my FastTrace tool for native server applications. The last thing you want to do when it comes to heavily multithreaded applications is force all those threads to block on a synchronization object when you turn on tracing The FastTrace tool gives you the highest possible tracing performance without losing the all-important flow of information Comment, Comment, Comment, and Comment One day, my friend Fran ois Poulin, who was working full-time on maintaining some code that someone else wrote, came in wearing a button that said, "Code as if whoever maintains your code is a violent psychopath who knows where you live" Fran ois is by no means a psychopath, but he did have a very good point Although you might think your code is the model of clarity and completely obvious, without descriptive comments it is as bad as raw assembly language to the maintenance developers. application and the amount of time I had, I dove in to what I call brute force UI automation I quickly wrote some code that could find each of the individual windows on the single screen that made up the application I remember that I was going to look up the specific Windows message that this program used, but I'd hit a roadblock waiting for access to the source code I've never been a fan of waiting around, so I decided to write code that would center the mouse over a specific window on the screen and send a mouse click to that point on the screen After a few more minutes of debugging and testing, I had a simple application that would randomly connect to any available server, verify that the connection was successfully established, and then terminate the terminal server session. Figure 3-9: Sample XSD file edited with Visual Studio .NET. As mentioned, Visual Studio .NET can also dynamically infer the schema from the currently displayed XML file. The task is actually accomplished by xsd.exe and can be easily repeated and controlled programmatically. The command line to use this tool is fairly straightforward, as shown here: xsd.exe file.xml Let's ask Visual Studio .NET to infer the schema for the sample address.xml file the file we designed to be compliant with the address.xsd schema. One would expect to obtain a file nearly identical to address.xsd. However, surprisingly enough, the resultant schema seems to be different, as shown in the following code. The schema inferred is lexically different from address.xsd but completely equivalent in terms of semantics. < xml version="1.0" > <xs:schema id="NewDataSet" targetNamespace="http://tempuri.org/address1.xsd" 96 The irony is that the maintenance developer for your code can easily turn out to be you! Not too long before I started writing the second edition of this book, I received an e-mail message from a company I had worked for nearly 10 years ago asking me whether I could update a project I had written for them It was an amazing experience to look at code I wrote that long ago! I was also amazed at how bad my commenting was Remember Fran ois's button every time you write a line of code Our job as engineers is twofold: develop a solution for the user, and make that solution maintainable for the future The only way to make your code maintainable is to comment it. By "comment it," I don't mean simply writing comments that duplicate what the code is doing; I mean documenting your assumptions, your approach, and your reasons for choosing the approach you did You also need to keep your comments coordinated with the code Normally mild-mannered maintenance programmers can turn into raving lunatics when they're trying to update code that does something different from what the comments say it's supposed to do I use the following approach to commenting: Each function or method needs a sentence or two that clarifies the following information: 132. xmlns:mstns="http://tempuri.org/address1.xsd" xmlns="http://tempuri.org/address1.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" attributeFormDefault="qualified" elementFormDefault="qualified"> <xs:element name="address"> <xs:complexType> <xs:sequence> <xs:element name="street" type="xs:string" minOccurs="0" msdata:Ordinal="0" /> <xs:element name="number" type="xs:string" minOccurs="0" msdata:Ordinal="1" /> <xs:element name="city" type="xs:string" minOccurs="0" msdata:Ordinal="2" /> <xs:element name="state" type="xs:string" minOccurs="0" msdata:Ordinal="3" /> <xs:element name="zip" type="xs:string" minOccurs="0" msdata:Ordinal="4" /> </xs:sequence> <xs:attribute name="country" form="unqualified" type="xs:string" /> </xs:complexType> </xs:element> <xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:EnforceConstraints="False"> <xs:complexType> <xs:choice maxOccurs="unbounded"> <xs:element ref="address" /> </xs:choice> </xs:complexType> </xs:element> </xs:schema> If the difference isn't obvious from looking at the source code, take a quick look at the file in the XML Editor, as shown in Figure 3-10. I set up the application to run infinitely, started it, and then let it run while I took care of a final few projects before heading home for the day I glanced over my shoulder once in a while, happy to see the application connecting and disconnecting every few seconds However, just as I stood up to leave, I turned around to take one final look at my test application and I saw that it had crashed I happened to be running under the debugger and noticed that the crash was caused by a memory leak, and the application was out of a particular Windows resource At first, I thought it was a problem in my application, so I spent some time scanning the source code looking for any place where items had been using that type of resource or perhaps misusing a Windows API. vb.net adobe pdf reader component Read & Parse a PDF file using VB .
