CTS, CLS, and CLR are basic concepts of the. NET Framework, but they are often ignored by programmers. A clear understanding of the three concepts helps. Net programmers write efficient and secure. net programs.Knowledge points involved• Basic concepts of. net• Relationship between CLs, CTS and common languagesAnalyze problemsThe full name of CLR is the common language runtime. Readers can understand CLR as
I have been busy with CTS testing recently. Some problems I have encountered will also be summarized to help you.
I. Questions about test sequence
The first test results contain about 100 fail results.
There are two ways to test the result for the second time. One is to test the result only for fail.
1) Enter l r under the CTS command
Terminal display:Session pass fail not executed start time planname0 7 0
1) CTS Universal type System (Common type systems)The CTS not only implements the variable compatibility type of COM, but also defines the type extension by means of user-defined types.Any to. NET platform as the target language must establish a mapping between its data type and the type of the CTS.All. NET language to share this type of system, to achieve seamless interoperability between them. The scheme
Background
The hidden node problem occurs in the Manet and WLAN-infrastructure networks. If node A and Node B no longer transmit the power range of the other party, collision is triggered when a and B initiate communication with AP (or node C) at the same time. the more hidden nodes, the higher the probability of collision, and the lower the throughput.
Solution
Increase the node transmission power and extend the transmission range
Before starting data stream communication, int

CTS frame is divided into nine parts:
Pai_options: The Parameter options accepted by the command line, in the Command package.
Device_requirements: device requirements, in the device package

to worry about learning the new language they are constantly introducing.CTS, Common type systems (Common type System)The CTS is a type system and language specification that ensures that the CLR is able to identify and process types, all. NET development language, regardless of the vs.net type or C #. NET type will eventually be compiled into the type of CTS that the CLR recognizes, so the
. NET FrameworkProgramDesign-Architecture Overview of the Net Framework Development Platform (FCL, CTS, CLS)
(1) FCL (. netframeworkclasslibrary):. NET Framework class library
FCL contains thousands of types, which are organized by namespace according to their functions.
Various. NET languages only define some rules, and we need to call the type in FCL to a large extent in actual use. These types allow us to use less language knowledge to create
Two, listen to whether the current test item is a accelerometer measurement test itemIn the first way, we can get the currently active activity similar to listening to the CTS test current test item. But because it is listening to all the activity in the Android system, it greatly reduces the performance of the system, so there is a more efficient way to pinpoint the test items currently being tested by the CTS
Test Solution for listening to Android CTS (2)
2. Check whether the current Test item is an Accelerometer Measurement Test.
As described in the first method, we can obtain the current test item of the Activity in the active state, which is similar to the test item of the CTS test. However, because it monitors all the activities in the Android system, the system performance is greatly reduced. Therefore, th
What is. NET? Origin: Bill Gates in 2000 Professional Developers Conference introduced a brand-new platform called next Generation Windows Service, which is later. NET. Software layer:. NET can be seen as a software layer between the operating system and the programming language, and it can support multiple programming languages, including c#,vb.net,c++,f#, and so on. The framework used to generate managed code, the platform: the traditional way of compiling is "source code → compile → executab
CTS test, the single failure is a common thing, want to find the cause is more troublesome, because the CTS command line, although providing a single test method, but only output results, at most, retain the device and host log, It is less common to debug with eclipse. Today, I think of this problem, the method of debugging CTS items under Eclipse is studied:Firs
· CLR (Common Language Runtime Library) is a CLI implementation that includes the. NET runtime engine and a class library compliant with CLI. Almost all. Net files we developedProgramAll are implemented based on CLR class libraries and run on the running engine provided by CLR.
· CLI (Basic Public Language) is a language and data format specification submitted by Microsoft to ECMA. CLR is the only implementation version of the Basic Public language so far. CLI includes the common type System (
Sensor CTS, tested for sensor.1. Test every sensorFrom the log, the sensor test begins with the action of activating the sensor, and the log statement is:SENSORSERVICE:SENSORDEVICE::ACTIVATE:IDENT=0X60BA9B48, handle=0x00000002,Enabled=1, Count=1Here the handle indicates which sensor, 0 is the acceleration, 1 is the electromagnetic, 2 is the direction, 3 is the gyroscope, and these are the necessaryRemember that. This is defined in Hwmsen.h. If the sen

The CLI is an open technical specification that was launched by Microsoft, Hewlett-Packard, and Intel in 2000 to the ECMA initiative. To be blunt, the CLI is a set of specifications, and the CLR is an implementation of the CLI. So what exactly is defined in this specification of the CLI?

Communication ProtocolRTS/CTSProtocol: The request sending/allowed sending protocol, which is equivalent to a handshake protocol and mainly used to solve the "hidden terminal" problem. "Hidden terminals" (hidden stations) means that base station a sends information to Base Station B, and base station C does not detect that a also sends information to B, so both A and C send signals to B at the same time, as a result, all signals sent to B are lost. "Hidden terminals" mostly occur in large units

CTS, CLS, and CLR are basic concepts of the. NET Framework, but they are often ignored by programmers.
CLR is the common language runtime. It can be understood as a set of engines containing. net programs and class libraries conforming to the basic structure of public languages. It is a standard CLI implementation. The so-called. NET Framework generally refers to the public Language Runtime Library.

RTS (Require tosend, send request) is an output signal that indicates that the device is ready to receive data, the low level is active, and the low level indicates that the device can receive data. The CTS (Clear tosend, send allow) is an input signal that determines whether data can be sent to the other, low-level, and low-level instructions that the device can send data to each other.
