app debugger

This is mainly to do asp.net development, but sometimes also contact with PHP, and I think that PHP has a lot of source code is worth learning, we are not learning the coding of PHP, but learning the source of ideas, or to avoid strong call for algorithm. As an unprofessional PHP developer, want to easily read and understand a PHP function module running details, build a PHP debugging environment, and then step to debug the program, to master the process of the entire operation of the program i

select a control with a yellow rectangle in the diagram, a drop-down list on the left to select the file, and a button on the right to start debugging. When the click to start debugging, the debugger will maximize the window, we found in the selected files need to debug the location, click on the left sidebar to add breakpoints to debug. When a program runs to our breakpoint, it can be debugged. here, we can use the shortcut keys to operate, th

When we debug a more complex problem, it is difficult to locate the problem, you need to try to set breakpoints, multiple continue, view variable values, and so on, sometimes need to set some special debugging variables and so on. This process often requires you to restart the debugger several times and restart these debugging commands. If debugging does not support reverse debugging, or if the reverse debugging performance is poor, the use of history

Http://blog.chinaunix.net/uid-23193900-id-3184605.html1. What is program debugging?The purpose of the program debugging is to find out the hidden faults in the program, correct those abnormal instructions, so that the program can work properly. 2. There are several different levels of debugging for a debug category program. The highest level of course is the programmer who visually observes and infers through their own eyes the faulty code and modifies it. The lowest level is theassembly code fo

GDB is the GNU Open source organization released a powerful UNIX program debugging tools, GDB can help engineers to complete the following 4 aspects of the function: Start the program, can be customized according to the requirements of the engineer to run the program. Let the program being debugged stop at the breakpoint specified by the engineer, the breakpoint can be a conditional expression. When the program is stopped, you can check what happened in the procedure and trace it. Dynamically ch

We have a lot of people around the use of XP system computer, we often do not know how to use the computer in the use of many applications, rather than the debugger in our computer is not a special book order, this software is actually used to maintain and correct the error of a very important function, if our notebook in the Run program, Pop-up the ToolTip window how to solve the problem, you need to close it, immediately to see how to shut down the

Because the running program is protected by Windows, even if the virus is detected, it is often killed and cannot be deleted. What if anti-virus software kills the virus? In the past, it was generally recommended to kill in security mode or DOS mode. There is now a new method called "specify the debugger in the Image File Execution options". This method should be feasible. The principle is to modify the registry so that the virus cannot be started the

To let the program stop:An important feature of the dynamic debugger is that it stops the program so that we can observe the immediate situation of the program.But now we do not need to study how to break the breakpoint, the system has helped us to activate the first breakpoint. When the debugging process is created, the system will help us set a INT3 breakpoint in Ntdll.dll, and we'll let the program break down here.Switch (debugevent->u.exception.ex

(The "Stupid Way" I used is to manually remove Class Point (functions with very low abstraction levels such as set/get + common onwin messages) + when hit, With debug output, dynamic outputs call sequence. But in the final analysis,Finding an accurate call stack is the "core") The reason for this article is: 1) When debugging com code, a "read violation" error is thrown because a null pointer is referenced. however, the exception lies in the break, but it is 108,000 away from the final bug

Debug Win32 Assembler with vc6 debugger source code Using a good debugger is undoubtedly crucial to learning Win32 Assembly. I prefer the powerful debugging environment of VC rather than makefile files.Programming Environment: vc6.0 and masm32v8 The method is as follows:1.

In fact, the debugging functions of Zend Studio (hereinafter referred to as "zde") are divided into internal debugging and remote debugging. Internal debugging is performed using zde's built-in PHP (four or five versions ). Code Preliminary debugging focuses on remote debugging because it can fully simulate a real running environment. Remote debugging requires the support of components on the server side. The content of today is how to install the debugging environment on the server side. T
