In the summary article on using the DotNetCharting control to generate a report Statistical Chart in. net, many bloggers have proposed "1. How to Deal with the generated images with hyperlinks directed to the official website? 2. After using this control, the image can be displayed. However, a small problem is found. The hyperlink is hidden in the upper left corner of the graph and below the graph. After you move the cursor to the two areas, you will click the link to http://www.dotnetcharting.c

++ classes respectively. A, B, C, and D are class objects, and the setvalue method is used to change a member variable of these class objects.
The above shows that C ++ConstClass object,You can only call its constMethod,And the constThe method cannot modify member variables,This constThe method can beNon-constClass Object call.
A. setvalue (10) can be executed, while running C. setvalue (10) is incorrect. For a pair of comparisons, we can see that
, it tends to be elsewhere, such as in the application code.
3. Of all the complexities in C ++, some areessential, some are unnecessary (Technical embarrassments, like yousaid). What're those, exactly? What's the right attitude towards themwhen learning or using the language? -Pongba
This is too big a question for a shortanswer, but I'm convinced that it wocould be possible to design a C ++ likelanguage of maybe a tenth of the size of C ++. the exercise wowould
public class Factorial {public static int factorial (int x) {if (x throw new IllegalArgumentException ("x must be>=0");}int fact = 1;for (int i = 2; i Fact *= I;}return fact;}public static void Main (String args[]) {System.out.print (factorial (10));}}
This is made using recursive algorithms.
public class Factorial2 {public static int Factorial2 (int x) {if (x throw new IllegalArgumentException ("x must be>=0");}if (x return 1;} elsereturn x * FACTORIAL2 (X-1);}public static void
Program{static void Main (string[] args){Dynamic dyn = 1;Object obj = 1;
Rest the mouse pointer over dyn and obj to the theirTypes at compile time.System.Console.WriteLine (Dyn.gettype ());System.Console.WriteLine (Obj.gettype ());}}
The WriteLine statement displays the Run-time type of dyn and obj. At this point, both have the same integer type. The following output will be generated:
System.Int32
System.Int32
To see the difference between dyn and obj, add the following two lines be
visual| compilation
The compiler for Visual C # is significantly different from the compilers of previous programming languages. The biggest difference is that the previous program compiler is to compile the program code to build the machine language that can be used directly for the computer. Although the Visual C # compiler can also compile the written program code into an EXE or a DLL file, this file is just an Il file (intermediate language), whic
vs.net code is compiled into intermediate language (intermediate Language,il). When the application runs, a real-time compiler (Just-in-time compiler, or JIT) compiles the IL code into machine language. In theory, it means that it is possible to construct a. NET runtime environment for a non-Windows platform, but there are no official messages about such systems. Il
It is worth noting that the slider implementation of this page is not very familiar with the artist, if you are interested, you can understand that Kazakhstan has recently developed a tax function. It is worth mentioning that the slider implementation on this page. Everyone knows that most programmers in reality are not very familiar with pages and art.
I am myself, but I prefer to do it myself. Not much nonsense. :
Implementation result:
Some js Code:
The Code is as follows:

Maybe a lot of people know we have to pack the program into a DLL and throw it out, but what is the specific implementation process in it?Assemblies are made up of metadata and IL. Il is a CPU-independent language, Microsoft's several experts consulted the outside of the compiler's work, developed. Il is a bit more advanced than most machine languages.
Boxing and unpacking are the actions that are performed to convert between value types and reference types.1. boxing occurs when a value type is converted to a reference type2. unpacking occurs when a reference type is converted to a value typeThe above two sentences are not difficult to understand, but deep understanding, it will take some space to explain.Let's look at what happens when we start boxing, here's the simplest packing code in a rowObject obj = 1;This line of statements assigns the
1-2-4. Calculation of the filtering capacitor of the series-connected Switching Power SupplyWe also started from the current flowing through the energy storage inductor as the critical continuous current state, analyzed the charge and discharge process of the energy storage filter capacitor C, and then calculated the value of the energy storage filter capacitor C.Figure 1-6 shows the voltage and current waveforms of each point in the tandem switching power supply circuit when the tandem switchin
limitation of dynamicproxy Because only the virtual side of the non-sealed class must inherit the original class. Method "can be intercept, Which is insurmountable. Aop.net's original implementation is probably the same idea. (Also worth mentioning, Castle The official homepage of. dynamicproxy includes the blog source zhengyulu. Introduction to Castle. dynamicpro in the blog XY used Article Links ~~, See: http://www.castleproject.org /Index. php/dynamicproxy) Of course, from a technical
when we obtain list data, we often use the form of pagination. For example, if one page contains 20 pieces of data, but for the convenience of paging at the front end, the backend must pass
Totalcout parameters. In this way, the front-end will know pagecount = math. Ceil (totalcount/pagesize) and calculate the total number of pages. In the traditional method, we need to package on the underlying list.
A class, and then add a totalcount attribute to the class, as shown below.
