My personal conclusion: Recently I saw network programming come across trace statements, but I don't know where to output them. I did not find any materials for one night. Today I finally found them on csdn, the method is as follows:
1. Add a trace statement to MFC
2. In tools> MFC tracer, select enable tracing and click OK.
3. debug and run go (F5) (Note: not execute '! 'The reason why we couldn't see
Debug| Namespace Summary
There is a System.Diagnostics namespace in the. NET class library that provides a library of classes that interact with system processes, event logs, and performance counters. This includes two class--debug classes and trace classes that are useful to developers. This article describes some of the basic uses of these two classes, designed to improve the development efficiency of a broad range of developers.
Use the Debug clas
Starting from this section, we will analyze the source code of each amps module. Chinese comments are added to the main sections.
The tracing function is similar to the logging function used by software, but the recorded information is more detailed than the log. It can be used to see the running track of the entire code. amps supports the following trace levels:
Error
Warning
Debug
Debug_2
Info
The following three tracking modes are supported:
Trace macro is very useful for program debugging in VC and has functions similar to printf. This macro only appears in the debug version of the program, when release is enabled, the macro disappears completely, helping you reduce the amount of code during debugging.
The format is as follows:
Trace ("ddddddddddd ");
Trace ("Wewe % d", 333 );
There are also trace0,

This macro only appears in the debug version of the program. When release is used, the macro disappears completely, helping you reduce the number of debugging tasks during release.CodeQuantity.

Trace macro for the VC under the program debugging is very useful things, with a similar function of printf, the macro is only in the debug version of the program appears, when the release of the macro is complete message, thus helping you to adjust the release also reduce the amount of code.
The use is very simple and the format is as follows:

If the SQL _trace parameter is set to true, the entire instance will be tracked, including all processes: User processes and background processes, which may cause serious performance problems and must be used with caution in the production environment.

For people engaged in Android development, encountering ANR (application not responding) is a more common problem. In general, if a ANR occurs, the system will generate the trace file in the/data/anr/directory, by analyzing the trace file, you can locate the cause of the ANR. There are many reasons for the ANR, such as high CPU use, the event did not get timely response, deadlock, etc., the following will b

William Kennedy wrote two articles about go debugging, very good, deliberately translated a bit, deepen memory. This article is one of these: Stack traces in Go. The other is Scheduler tracing in Go.
The stack trace represents the stacking trace, which is an ordered collection of one or more stack frames. When the progra
I recently read the. NET developer debugging strategy. The book is good, but the translation is poor. However, some of the debugging experiences introduced in this article are good and rewarding.
Next I will summarize some of the applications of debug and trace in this book, which is regarded as a kind of Reading Notes.

Tags: Oracle performance databaseWhen Oracle queries come with efficiency issues, we often need to understand the problem so that we can solve the problem. Oracle provides trace information for SQL execution, which contains textual information about SQL statements, some execution statistics, waiting during processing, and information generated by the parsing phase, such as generating execution plans. This information helps you to diagnose performance

What do you mean, no trace browsing?
No trace browsing means that when surfing the Web page, the password will not be saved, the Internet address will not be saved, and the exit is to delete the cookier. One word is that you have browsed the site others do not know.

As I said earlier, Oracle's external tables can be used to access warning log files, but Oracle's external tables can be very flexible to use.
After creating the appropriate directory with the Create Directory command, we can grant access to the directory to other users so that other users can access files on many hosts through external tables.
Let's take a look at an example of using an external table to access a trace file (my example is done with
