advanced windows debugging

MFC advanced debugging technology 1. Use of TRACE macros The TRACE macro is like the printf function we used in the C language before, so that the program outputs some debugging information during the running process, so that we can understand some of the program status. However, one difference is that the TRACE macro outputs only in the

. For example, $function will be replaced with the function name where the breakpoint is located. Some other keywords are described in detail in the "when breakpoints are hit" window.B. Use a variable name that is enclosed by curly braces {}, so that the string is replaced with the value of the variable.Here is the effect of monitoring breakpoints, and note that you can only view the results in the Output window of Visual Studio.The benefit of monitoring breakpoints relative to logging is that y

When you first started using Eclipse's debug, will only F5 F6 F7 F8, and even F7 are not very engaged in understanding how to use, when the capital is shallow, can not touch the need for complex debug code, slowly work deeply, the scene to touch more, you need a variety of debug techniques to improve the positioning of bug efficiency, Before looking for help to check the problem, see him open a variety of Windows debug all kinds of slip is envy envy h

I just saw the Visual C #2005 advanced debugging technology.Implementation debugging is executed by attaching a debugger to a running process, and post-diagnosis is performed by dumping files.This includes memory check, computing call stack, setting breakpoints, and viewing threads.Dump files have the DMP extension, and several tools can be used to create one dum

runtime, including the number of calls, can help the programmer to analyze the program's running flow. Gprof implementation principle: By the time you compile and link the program (using -pg compile and Link options), GCC adds the name Mcount (or "_ in each function of the application) Mcount ", or" __mcount ", a function that relies on the compiler or the operating system, which means that every function in the application calls Mcount, and Mcount saves a function call graph in memory, and f

Save and then return to Xcode to reload your script:(LLDB) Reload_scriptTest your module_summary:(LLDB) Lookup-s viewwillappearYou will get some code similar to the following:Hits in UIKit1 hits in WebKit4 hits in AllocatorThat's all! You've already done it! You have created a more powerful script from scratch. You will use this script to search for code in later chapters. The summary option is a powerful tool when you develop a broad search scope and then want to narrow the scope further

image data through JavaScript. Later crossorigin , the label solves the problem by introducing attributes. If used crossorigin="anonymous" , it is equivalent to anonymous cors, and if you use ' crossorigin= ' use-credentials, it is equivalent to a certified cors.Since labels can do this, why can't labels do this? The browser vendor then adds the same attributes to the tag to address the crossorigin security restrictions described above. Now Chrome and Firefox support for this property is ab

the data is sent to the server. For example:Www.cnblogs.com?backurl=http://www.cnblogs.com?a=1 The workaround is to encode the parameters following the Backurl using encodeURIComponent (), with the result:Www.cnblogs.com?backurl= HTTP%3A%2F%2FWWW.CNBLOGS.COM%3FA%3D1Scenario two is for the query string, and also for the name and value of the query parameter are encoded.Four logging errors to the serverIf the error information in the front and back end of the summary record, can greatly facilitat

Debugging Policy Chapter 1 debugging process 1. The key to successful and efficient debugging is to find accurate error information. 2. Once an error is found, more may be found. Similar code may have similar errors. 3. Learn how to prevent future errors from mistakes 4. For the new code, you do not need to perform a test to determine whether it has any errors. C

Windows GUI code with Windows message Problem debugging toolA long time ago, I remember the saying that human beings are different from the standard of animals is the use of tools. Also in the software development industry, the use of tools is also a master and entry-level players of the main difference,Experts often rely on the use of tools in the critical time

If you often write Windows scripts with VBS or JS and only know how to debug your program with a print variable Then you can go and spit the blood, and then read this article. Any type of Windows script can be debugged with a script debugger, with several script debuggers, the simplest of which is Microsoft Script Debugger, in Windows2000 can be installed in the form of

This article mainly describes how to use the remote debugging tool and uses the simulator of Pb (Microsoft platform builder) for testing. I. Simulator Emulator is a part of Pb. It is used to debug the kernel and Applications created under Pb. The simulator can simulate a Windows CE physical platform in a PC. But in fact it is just a user program running at the CPU Ring Level 3. Therefore, its running speed

Overview of all components Picture from Windows internal Above the horizontal line is a user-state process, and the following components are kernel-State services. User-mode threads run in a protected process space, although they still have the right to access system space in kernel execution mode. Therefore, the processes, service processes, user applications, and environment subsystems supported by the system use their own private process address s
