The ObjRef Class When a MarshalByRefObject object is being remoted, the NET Remoting system packs all the relevant information into an ObjRef object An ObjRef object is a serializable representation of the original MBR object This intermediary object enables the NET Remoting system to transfer an object reference across the boundaries of AppDomains In effect, the entire action of marshaling by reference can be summarized with the creation an ObjRef object An ObjRef object contains information that describes the type and the class of the object being marshaled, the exact location, and any communicationrelated information such as port and protocols The ObjRef instance is created on the server when the MBR object is first referenced; next it is transferred into the target AppDomain, possibly in another process or on another machine. vb.net read pdf file text: How to Convert PDF to Text in .

NET : ... 0 Dim line As StringBuilder = New StringBuilder() ' Read PDF file's text content and ... This solution seemed relatively straightforward because all I had to do was enumerate the modules' symbols and sort the array of functions I had all the necessary data to do this I thought that SWS, like the WST, should keep each module's execution counts for a run in a separate data file I favor that approach because if you don't want a particular application run, you can delete it from the overall merged data set The WST uses the <module name><run number> naming format, but I wanted SWS to use a <module name><run number>SWS scheme so that I could eventually write a graphical program to make combining all the runs easier After I decided how I wanted to approach the run-time data processing, I considered how to generate the actual order file As I already mentioned, I needed to concatenate the individual runs. However, when I thought about producing the actual order file, I realized 683. read pdf file using itextsharp vb.net How to read PDF file using iTextSharp in ASP. NET ...

On the client, the ObjRef object is then deserialized, and the real proxy is created to access the remote instance of the MBR object This operation is globally known as unmarshaling The RealProxy Class RealProxy is an abstract class that represents a remoting proxy Any remoting client transparently uses an instance of this class to issue calls to the remote object The overall NET Framework model for distributed programming is designed to create the illusion that remote objects are actually working locally This is true for NET Remoting as well as for Web services, even though the effect is obtained with radically different techniques Note NET Remoting creates the local instance of the remote object using dynamically created proxies that result from the run-time deserialization process Basically, the deserialization of the ObjRef class generates a transparent proxy to handle user calls. Figure 6-11: CountC control flow diagram. However, application of the simple baseline path method to identify the set of basis paths and the expected result predicted for each basis path test quickly reveals two errors of commission. The CountC function has four conditional clauses and a cyclomatic complexity of five. Therefore, there are five basis paths for this function. Table 6-3 lists the set of basis paths and the inputs required to test those paths and the expected result, and Figure 6-12 illustrates each linear independent basis path. that I hadn't brought forward all the necessary data The order file needs the names of the functions as well as their sizes, but all I had planned to store were the function addresses Although I could have used the symbol engine again when generating the actual order file, the only way to get a symbol's size is to enumerate all the module's symbols Since I was already handling full symbol enumeration in the initial data generation phases, I thought I should just go ahead and add the function sizes to the file I didn't need to store the function names because I could always look them up by loading the PDB file for the binary. With Web services, a proxy class is statically added to the application's project at design time when the Web service is referenced as an external library The generation of the source code for the class and the subsequent addition to the project are automatically handled by Visual Studio NET However, the wsdlexe utility (part of the NET Framework SDK) allows you to generate the class yourself.. If you did find Russ Blake's Optimizing Windows NT and you read the chapter "Tuning the Working Set of Your Application," you might wonder why I didn't mention anything about bit sets and time intervals The Windows NT performance team implemented WST using a scheme in which a bit in a bit set represents each function Every so many milliseconds, WST writes out the bit set to record which functions executed in that time interval I've often wondered why they implemented WST that way At first glance, it seems like you do save some memory with the bit set, but you have to remember that there must be some way of mapping a function address to a bit I don't think the bit set scheme saves much more memory than my scheme. Figure 6-12: Linear independent paths in CountC function. Table 6-3: Basis Path Table for CountC Function Open table as spreadsheet Basis path Path Input Expected 1 2 3 4 A0 A0 A0 A0 A5 A0 A5 A1(F) A1(T) A1(T) A1(T) A5 A2(F) A2(T) A2(T) A5 A3(T) A3(F) A2(F) A4(T) A5 A2(F) D A AB AC 0 0 0 1 I believe the Windows NT performance team used the bit set scheme because they were tuning the operating system with WST In contrast, I'm looking at individual binaries, so it's an issue of scale When designing my data structures, I was concerned about one point: I wanted to simply increment a value whenever a function executed In multithreaded programs, I need to protect that value so that only one thread at a time is manipulating it My goal was to make the SWS run time as fast as possible, so the best choice was to increment the function count with the InterlockedIncrement API function Since that function uses the hardware locking mechanism (the LOCK prefix on an instruction), I can guarantee data coherency in multithreaded applications However, in Microsoft Win32, the largest data size that you can pass to InterlockedIncrement is a 32-bit value. The RealProxy class hidden behind the software creates the illusion that remoting clients actually work locally. The proxy is transparently invoked whenever a method is called on the remote object. The RealProxy class executes the method by forwarding any calls to the real object using the remoting infrastructure. 431 A1(T) Therefore, it's possible to wrap after 4,294,967,295 function calls Four billion is a large number, but some message loops could execute that much if you run your application long enough The WST program avoided this problem at run time by recording only when the function executed and then calculating the total executions after the fact, when it's easier to deal with the possible wrapping When tuning the operating system, the odds are quite good that you could execute some functions more than four billion times However, with SWS, I'm willing to take the chance during my initial design and perform some testing to determine whether function count wrap is a problem Function count wrap might be less likely with my design because I left the hooks in so that you can start and stop the data collection at will. Thus, each time you run the application, you can generate data only in the cases in which you need it In the extremely rare case in which you do execute a function more than 4 billion times, you have two options The first is to implement the data counting variable as a 64-bit integer and have a per-module synchronization object to protect all the bits The other option is drastic in that I will need to implement the SWS run time to work like WST Of course, the wrapping problem happens only on Win32, so another option would be to implement SWS for Microsoft Win64 only, because there's no way you'll ever hit 18,446,744,073,709,551,615 function executions in your lifetime You can see how simple the file format actually is by looking at Listing 19-2. If you want to play with the transparent proxy object yourself, you can get a reference to it by using the following code: RemotingServices.GetRealProxy(localObject); The variable localObject is the local instance of the remote object that you have created using the new operator. (More on this in a moment.) As mentioned, RealProxy is only an abstract class. The actual proxy object belongs to the RemotingProxy class in the System.Runtime.Remoting.Proxies namespace. A2(T) I quickly realized that I needed a common base class to handle all the file manipulation, which is SWSFILEH and SWSFILECPP The class is really nothing CSWSFile defined in more than a wrapper over your normal Win32 file manipulation Listing 19-2: FILEFORMATH 684. Let's take the plunge into NET Remoting and start building a service that can be exploited and consumed from remote clients In 13, we'll extend the service to make it openly available to Internet clients too In this way, you can really grab the essence of NET Framework distributed programming and understand the key differences that keep NET Remoting and Web services separate even though they're both children of a common model for remotable objects A NET Remoting server and a Web service are both NET Framework classes As such, they can inherit from a parent class and can be left open to further inheritance As you'll see in more detail in 13, a Web service class can optionally inherit from the WebService class, but there is no syntax obligation A NET Remoting server class must inherit from MarshalByRefObject The object-oriented nature of the . vb.net code to extract text from pdf How to Extract Text from PDF Document in C#, VB .
