Today, my classmate asked me a question, I think it is very interesting, now recorded down to discuss. The problem is: in a table, there is a field that is allowed to be empty, and null can be repeated, but a value that is not NULL needs to be unique. The table structure is created like the following code The following are the referenced contents:CREATE TABLE TEST_TB(TestID int NOT null identity (1,1) primary key,Caption nvarchar (MB) n

If we use the tmainmenu control to design the following menu: This menu is stored in the form source file as follows: Object mainmenu1: tmainmenuleft = 160top = 104 object file1: tmenuitem caption = ' file' object new1: tmenuitem caption =' new' end object open1: tmenuitem caption = ' open' end object save1: tmenuitem

How to automatically number pictures in a Word document In fact, as long as each document writer follows the following steps to number the picture, you can make the merged document automatically number the picture: Add a caption like "Figure 1 XXXX" below the picture To make it easier to find and read, we need to number the picture and insert the caption in the following steps: (1) Position the cursor w

Excerpted from http://www.cnblogs.com/wuyifu/p/3424621.htmlA JSON object is generated in the background, but some data may be invalid or illegal, so you need to do some exceptions at the foreground, such as deleting.There are many ways to delete JSON, directly using the Delete JSON object.Examples are as followsJS Codevar columns = [{Name: "Bigtitle", caption:reportdata.bigtitle,children:[{Name: "OrgName", Caption: "Organization structure name", Width

}; Mylist.push_back (5); And then again, Python creates a Dictionary that's as simple as 6. Copy the Code code as follows: Mydict = {5: "foo", 6: "Bar"} Print (Mydict[5]) Cut, C + + itself has a map type, and now a hash table unordered_map, more like: Copy the Code code as follows: Auto Mydict = Std::unordered_map {{5, ' foo '}, {6, ' Bar '}}; Std::cout Lambda expression Python presents a great artifact, a LAMBDA expression in 1994: Copy the Code code as fo

The example in this article describes the closure usage in Python. Share to everyone for your reference. The specific analysis is as follows: What is a closure package? Simply put, closures are based on different configuration information to get different results Let's take a look at the professional explanation: Closures (Closure) are short for lexical closures (Lexical Closure) and are functions that reference free variables. This quoted free variable will exist with this function, even if it

) )); }}---------------------Split Line------------------------function currying:is to transform a function that takes multiple arguments into a function that takes a single parameter (the first parameter of the original function),and returns a technique that takes the remaining parameters and returns the result of the new function.My understanding is that you need to call a method a () repeatedly, and its parameters have a parameter in a certain condition value is not easy to change,Each call

First, let's look at sum (and bit). What we need is this logic: When two inputs are not the same, the output is 1, so the operator should be OR. When two inputs are the same, the output is 0, which can be implemented by combining the two groups of and not. The final logical combination diagram is

(add([1, 2, 3, 4],10)); Fortunately, there are map and reduce functions. If we want to add 1 to each item and then summarize it in this mode, we need to replace the functions in map. Let's take a look at the implementation of colialization: Var adder = function () {var _ args = []; return function () {if (arguments. length = 0) {return _ args. reduce (function (a, B) {return a + B;}) ;}[]. push. apply (_ args, []. slice. call (arguments); return ar

follows: Auto mylist = std: vector {1, 2, 3, 4 }; Mylist. push_back (5 ); You can also say that creating a Dictionary in Python is as simple as what it is. The code is as follows: MyDict = {5: "foo", 6: "bar "}Print (myDict [5]) Cut, C ++ itself has the map type, now there is another hash table unordered_map, more like: The code is as follows: Auto myDict = std: unordered_map {5, "foo" },{ 6, "bar "}}; Std: cout Lambda expressions Python provides a big artifact. in

To solve this problem, for a computer, it must have an ability to bootstrap, with additional equipment (BIOS) To understand the BIOS, you must understand the computer architecture The computer consists of five major parts Arithmetic: Responsible for logic and add and subtract operations; Controller: Notifies the operator where to access the data; Memory: Refers to memory, address the storage dev

How to implement binary additions by logic circuitsThe first binary addition can be disassembled into two steps: Add and carry. + Addition 0 1 0 0 1 1 1 0 + Rounding 0 1 0 0 0 1 0 1 Add this step can be done by the XOR gate, carry this step can be used with the door to complete.However, the two logic gates can only be compo

truth table. This is called the half-adder, because it only considers the addition of two separate bits, and does not consider the possibility of a low bits. 4. Extended truth tables and full Processors If we use the low-level incoming bits as the third input (input), that is to say, in addition to two input values A and B, there is also an input carry, the problem is how to get the sum (SUM) and carry (carry) of the output (output) with three input

It is very convenient to use the ASM package to modify the class file, but unfortunately, ASM does not provide a ready-made method modification tool, so we can use the powerful bytecode operation capability provided by it, do it yourself: The basic idea is as follows: assume that the operation class is a, and assume that the method to be added is Ma. To facilitate the operation, construct Class B and add the MA method of Class B to Class, with this idea, you can quickly implement the following c
