Today, I am working on. NET ProgramWhen a virtual directory is added, the following error occurs: "analyzer error" --- "failed to load type". However, I tested it in Vs and found the relevant information online, after adding the bin folder under the virtual root directory, the problem still persists. It suddenly reminds me that there is such a setting in the virtual directory, as shown below: The default Asp.net version is 1.14322. I changed it

Introduced Mixer wants to provide custom routing, SQL blacklist to prevent SQL injection attacks in the proxy layer, and the cornerstone is to parse the SQL statements sent by the user. That's my first big lexical analysis and grammar analysis. So far, I've just implemented a simpler lexical analyzer to decompose SQL statements into multiple token. And for the syntax analysis from the token, build the SQL AST, I now really have no experience (compil

About 5 things you don't know about Java performance Monitoring-part 2nd: Java process monitoring with JDK built-in analyzer Fully functional built-in analyzers, such as Jconsole and VISUALVM, are sometimes more expensive than their performance costs-especially in systems running on production software. So, in the 2nd article focusing on Java performance monitoring, I'll look at 5 command-line profiling tools that allow developers to focus on one asp

"count value" (count), which determines the degree of detail of the analysis, the smaller the value, the more frequent the sampling, and currently consumes a lot of system resources. Each counter can choose to sample only kernel code, sample user state code, or all samples. Finally, some events contain a "unit mask", which is used to further limit the types of events to be counted. 1.1 Opcontrol main parameter Description --init Load the Oprofile module when needed and start the Oprofile driver

If the primary database fails, Microsoft's SQL Server may enthusiasts down. See how you can handle this event to find out how to repair the primary database with Enterprise Manager and Query Analyzer. As an administrator of Microsoft SQL Server, you must know how to fix a crashed primary database. The primary database holds your login information and, most importantly, pointers to all of your databases. If you do not have a primary database, you will

When the stack is loaded to ReadLogs, it tries to break down this function call into a friendly name by using the list of loaded modules. First, it obtains the memory address for calling (0x1000113c), and then looks for the DLL containing the

character input, and then use your own class to support the rollback capability. The compilation principle providesBuffer pairTo put it simply, it is to open up two buffers and set the buffer size to N characters. Each time, N characters are read into the buffer, and character operations are performed on the buffer. If the data in the current buffer zone has been processed, read N new characters into another buffer zone, and then perform another operation as a new buffer zone. This data structu

In the process of scanning the programming language source program, it is decomposed into lexical analysis methods of all kinds of words.Compiling a read word process, from the input of the source program, the identification of the individual meaning of the word, that is, the basic reserved words, identifiers, constants, operators, se

program.Stack and multi-stream applications The preceding memory diagram (figure 6) only shows a portion of the memory associated with the stack. However, each stream has its own stack, because each stream needs to understand its own history, which is completely independent from other streams in the process.Generally, the stack grows down (from high to low memory
