12th: puzzling NTDLL breakpoint
Handle unexpected user breakpoints in Ntdll
I haven't written anything for a long time. This time, I wrote a training ppt (VC usage and debugging skills) to help me remember to write something.The following articles refer to http://www.debuginfo.com/tips/userbpntdll.html, but it is not a translation, and even English is too bad.
During program debugging, a dialog box is displayed suddenly, which displays the following i

Switch the Navigator view to the Breakpoint Navigator view, or you can use the shortcut key command+7 one step, the keyboard is the window style user Command key is the win key (with Microsoft logo), and then click on the lower left corner of the + sign, select Add Symbolic breakpoint This option2.

Typically, Web servers (such as Apache) turn on support for the continuation of a breakpoint by default. Therefore, if you provide a file download directly through a Web server, you can enjoy the benefits of a breakpoint continuation without having to make a special configuration. A breakpoint continuation is a range header that is added when an HTTP request is i
In recent days, a problem occurs: breakpoint debugging in eclipse.ProgramAt that time, the breakpoint I set will not be tracked. I have been confused for a long time. I have read a lot of information on the Internet and have not been able to solve my problem. This morning, I tried to replace the eclipse workspace with another drive letter. Try breakpoint debuggin
Use vc6.0 to debug C LanguageProgramIt is always interrupted by a breakpoint after an action. It is strange that the message "User breakpoint called from code at 0x7c81a3e1" is the same each time, and the breakpoint is not mine either.CodeIs unable to see the source code assembly
Check breakpoints and find that there is no
Some students can use the source code search method. Indeed, this method often works for a relatively simple page. However, for relatively complex pages (for example, pages are embedded with many script files and fragments, large object-oriented implementations are used, and the implemented code is hidden ), it may be difficult to find it.
In Javascript debugging, we often use breakpoint debugging. In fact, we can also use the
# Ifdef MTK_ASSERT# Define assert (p) do {\If (! (P )){\LogPrint ("Assertion failed: % s \ nFile: % s \ nLine: % d \ n", # p, _ FILE __, _ LINE __);\_ Asm {int 3 }\}\} While (0)# Else# Define assert (p)# Endif
From Baidu Encyclopedia:INT3 breakpoint is a type of breakpoint, And the shortcut key in such as Ollydbg is F2, which is a very common breakpoint type. The
completion information is also printed when the download is complete.
Let Destination = Alamofire.Request.suggestedDownloadDestination ( directory:. Documentdirectory, domain:. Userdomainmask) Alamofire.download (. Get, "Http://www.hangge.com/favicon.ico", destination:destination) Progress {(Bytesread, Totalbytesread, Totalbytesexpectedtoread) in let percent = Totalbytesread*100/totalbytesexpectedtoread Print (downloaded: \ ( Totalbytesread) Current progress: \ (percent)% ") } .

After reading the information on the Internet, I laugh and cry. According to a Netizen's comments: "You look at Microsoft's tips, you never know where the problem really happened." "I used to be a believer in MS, but gradually began to oppose it slowly. I think a lot of MS product problems, is completely the idea of confusion or mistakes. Here are some summaries:1.I'm having a strange problem debugging a program in Visual Studio 2005 tod
This week completes a breakpoint continuation function.The logical simplification of our game in loading maps is this:1. First verify that the map file (many files) is complete with the local MD5 file. (There are many steps in the middle, and any step fails to think the map is incomplete)2. If complete, load the map directly.3. If not complete, the backend server needs to be sent back to the full map via an HTTP protocol.Now it is time to add a
Today in the test of the Beef Brisket Web page encountered a problem need to use breakpoint debugging to solve, but after the point of addition to the following situation:
Then depressed, check the Baidu after the following results:
Breakpoint debugging is a great tool in VS, and with it we can quickly navigate to the problem of the code. In some cases it can cause the program to stop at a
Principle Analysis
In the development, "the breakpoint continues to pass" this kind of function is very practical and is common, sounds also has "the force lattice" the feeling. So usually we are interested in studying how this function is achieved?In Java, there is also a lot of data on the web to achieve similar functions. However, most of them are to take a demo and then post the source code, the actual principle of its implementation has a detail
Apply to PowerShell 3.0 or higher!
PowerShell Ise only supports line breakpoints: It lets the script run to a specific debug line: You can press F9 to add or remove breakpoints. However, it is necessary to ensure that the script has been saved (the default untitled file may not be possible).
There is also a more advanced approach: a dynamic breakpoint, or a conditional breakpoint, which does not specifica
After the installation configuration succeeds Xdebug, the breakpoint is not entered at the time of debugging, but what's going on?
I configured the start address here, the corresponding breakpoint in the program
But when the program executes to the breakpoint position, it doesn't stop entering the breakpoint.

Breakpoint debugging is a required function for programmers. Unity3D supports writing js and c # scripts, but many may not know. In fact, Unity3D can also perform breakpoint debugging on the program. However, this breakpoint debugging function is limited to the MonoDevelop editor that comes with Unity3D. However, Visual Studio cannot be used. I heard that there i
Ruling pin-breakpoint
The rod of the ruling, codenamed "ruling", is a very powerful weapon in fantasy, has the power to judge the ruling, and has the responsibility to monitor the sentient beings.

In the project, we will often encounter the need to download the program, such as downloading music online, download pictures and so on, today I will introduce the use of ASIHTTPRequest download example, support for the continuation of the breakpoint, the use of asihttprequest download and the principle of the continuation of the breakpoint in my blog: http ://www.cnblogs.com/webapplee/p/3784599.html has a
