The default projects that the Visual C++ wizards create are at warning-level 3, which corresponds to the /W3 switch in CLEXE The next step up is warning-level 4, /W4, and you should even have the compiler treat all warnings as errors with /WX These levels are all easy to set in the project Property Pages dialog box, C/C++ folder, General property page In the Warning Level field, select Level 4 (/W4) Two fields down is the Treat Warnings As Errors field, which you'll want to set to Yes (/ WX) Figure 2-3 shows both fields properly filled out Although I can almost justify making the global statement "All builds should compile with warning-level 4, and you should treat all warnings as errors," reality intrudes to force me to temper this remark The Standard Template Library (STL) that comes with Visual C++ has many warning-level 4 issues in it. vb.net read pdf file contents: how to read PDF file using vb .

The compiler also has a few problems with templates Fortunately, you can work around most of these issues You might think that just setting the warning level to 4 and turning off treating warnings as errors would be fine; in fact, that scheme defeats the purpose I've found that developers quickly become desensitized to warnings in the Build window If you don't fix all the warnings as they happen, no matter how innocuous a warning seems, you'll start to lose more important warnings because they'll be hidden amid the output stream The trick is to be more explicit about which warnings you want to handle Although your goal should be to get rid of most warnings by writing better code, you can also turn off specific errors with the 36. vb.net read pdf into byte array [Solved] how can i read PDF file information using vb . net ...

Figure 11-3: Windows Reliability and Performance Monitor. Applications can implement custom performance counters to track private object usage, execution timings, or most anything else interesting in regard to performance. A comprehensive set of performance counters planned in the design phase and implemented early will always benefit performance testing and analysis during the entire life of the product. Many books and Web references contain extensive additional information in the area of performance testing. Both the patterns & practices Performance Testing Guidance Project at http://www.codeplex.com/PerfTesting/ and http://msdn.microsoft.com/en-us/library/bb924375.aspx are great places to find further information about this topic. Testing the XmlRecordsetWriter Class For .NET Framework applications, using the XmlRecordsetWriter class is no big deal. You simply instantiate the class and call its methods, as shown here: void ButtonLoad_Click(object sender, System.EventArgs e) { // Create and display the XML document CreateDocument("adors.xml"); UpdateUI("adors.xml"); } void CreateDocument(string filename) { DataSet ds = LoadDataFromDatabase(); XmlRecordsetWriter XmlRecordsetWriter(filename); writer.WriteRecordset(ds); } writer = new #pragma warning directive Additionally, you can use the #pragma warning directive to control the error level around specific headers A good example of lowering the error level is when you're including headers that don't compile at warning-level 4 The extended #pragma warning directive, first offered in Visual C++ 6, can lower the warning level In the following code snippet, I set the warning level before including the suspect header and reset it so that my code compiles with warning-level 4: #pragma warning ( push , 3 ) #include "IDoNotCompileAtWarning4h" #pragma warning ( pop ) You can also disable individual warnings with the #pragma warning directive This directive comes in handy when you're using a nameless structure or union and you get a C4201 error, "nonstandard extension used : nameless struct/union," with warning-level 4 To turn off that warning, you use the #pragma warning directive as in the following code. Notice that I commented what I was turning off and explained why I was turning it off When disabling individual warnings, be sure to restrict the scope of the #pragma warning directive to specific sections of code If you place the directive at too high a level, you can mask other problems in your code // Turning off "nonstandard extension used : nameless struct/union" // because I'm not writing portable code #pragma warning ( disable : 4201 ) struct S { float y; struct { int a ; int b ; int c ; } ; } *p_s ; // Turn warning back on #pragma warning ( default : 4201 ) One warning, C4100, "'identifier' : unreferenced formal parameter," seems to cause confusion about how to fix it If you have a parameter that's not being referenced, you should probably remove that parameter from the definition of the method. The ability of an application to perform under expected and heavy load conditions, as well as the ability to handle increased capacity, is an area that often falls under the umbrella of performance testing. Stress testing is a generic term that often includes load testing, mean time between failure (MTBF) testing, low-resource testing, capacity testing, or repetition testing. The main differences between the approaches and goals of these different types of testing are described here: Stress testing Generally, the goal of stress testing is to simulate larger-than-expected workloads to expose bugs that occur only under peak load conditions. Stress testing attempts to find the weak points in an application. Memory leaks, race conditions, lock collision between threads or rows in a database, and other synchronization issues are some of the common bugs unearthed by stress testing. Load testing Load testing intends to find out what happens to the system or application under test when peak or even higher than normal levels of activity occur. For example, a load test for a Web service might attempt to simulate thousands of users connecting and using the service at one time. Performance testing typically includes measuring response time under peak expected loads. Mean time between failure (MTBF) testing MTBF testing measures the average amount of time a system or application runs before an error or crash occurs. There are several flavors of this type of test, including mean time to failure (MTTF) and mean time to crash (MTTC). There are technical differences between the terms, but in practice, these are often used Figure 4-11 shows the output of a sample application that creates the XML file and then displays it in a text box on the form. However, if you're doing object-oriented programming, you can derive from a method that no longer needs the parameter and then you can't change the base class The following code snippet shows how to properly work around the C4100 error: // This code will generate the C4100 error int ProblemMethod ( int i , int j ) { return ( 5 ) ; } 37. // The following code properly avoids the C4100 error int GoodMethod ( int /* i */ , int /* j */ ) { return ( 22 ) ; } If you're not using STL, this scheme works well If you're using STL, it might work, but it might not Your best bet with STL is to include only the STL headers in your precompiled headers It makes isolating the #pragma warning ( push , 3 ) and #pragma warning ( pop ) around the headers much easier The other huge benefit is that your compiles will speed up dramatically A precompiled header is essentially the parse tree, and because STL includes so much stuff, precompiling headers will save lots of time Finally, to fully track memory leaks and corruptions in the C run-time library, you'll need to keep the STL headers together. interchangeably Low-resource testing Low-resource testing determines what happens when the system is low or depleted of a critical resource such as physical memory, hard disk space, or other systemdefined resources It is important, for example, to understand what will happen when an application attempts to save a file to a location that does not have enough storage space available to store the file, or what happens when an attempt to allocate additional memory for an application fails Capacity testing Closely related to load testing, capacity testing is typically used for server or services testing The goal of capacity testing is to determine the maximum users a computer or set of computers can support Capacity models are often built out of capacity testing data so that Operations can plan when to increase system capacity by either adding more resources such as RAM, CPU, and disk or just adding another computer. Figure 4-11: An ADO XML Recordset object that has just been created and its contents displayed in a text box on the form. The source DataSet object is fetched from the SQL Server Northwind database by executing the following query: SELECT employeeid, firstname, lastname FROM employees The XML file that is created in this way is successfully recognized by ADOdriven applications, as shown in Figure 4-12. 146 The debug C run-time library is discussed in 17 The bottom line is that you must compile at warning-level 4 and treat all warnings as errors from the start of your project When you first boost the warning level for your project, you'll probably be surprised by the number of warnings you get Go through and fix each one You'll probably notice that just fixing the warnings will solve a bug or two For those of you who think getting your program to compile with /W4 and /WX is impossible, I have proof otherwise: all the native sample code on this book's companion CD compiles with both flags set for all configurations Common Debugging Question: The STL supplied with Visual Studio NET is hard to read and debug. vb.net read pdf into byte array VB .NET code to read , convert PDF documents - Yiigo
