), then the specified default parameter is used:function Setdefaultvalue (param, defval) {var undefined;if (undefined = = param) {return defval;} else {return param;}}OK, that's all. Can be added later, do what you need to do it ~They are very simple to use. For example, function add, assuming that the incoming must be a positive number, and B can not pass, the default is 10:function Add (A, b) {var adder = Setdefaultvalue (b, 10);Validatetype (A, num
Today, I was asked a question. I think it is quite interesting. now I will record it and discuss it with you. The problem is: in a table, there is a field that can be blank. null can be repeated, but the value that is not empty must be unique.

The following code creates a table structure:
Copy codeThe Code is as follows: create table test_tb
(
TestId int not null identity (1, 1) primary key,
Caption nvarchar (100) null
);
GO
Solution 1:For this question, the first thought may be: Can I add a unique key to the Caption field? Well, let's proceed with this idea and create a unique index first.Copy codeThe Code is as follows: create unique noncluste

(
TestID int NOT null identity (1,1) primary key,
Caption nvarchar (MB) null
);
Go

The first idea for this question may be: Is it OK to add a unique key to the caption field? OK, let's follow this thread and create a unique index first.
Copy Code code as
(getcurrenttask, $ FA );
Ch: = char (P ^); {the result is Ch = 'T '}
P: = PTR (getcurrenttask, $ Fa + 1 );
Ch: = char (P ^); {the result is Ch = 'D '}
3. String string character array and pointing word
Difference and connection between pointer pchar of string
These three have the same basic concepts, but there are some very subtle differences. errors may occur if you do not pay attention to programming.
1. Use a pointer to a string. If it does not end with 0, an error will occur during running.
attributes.Common PropertiesCommon properties have been implemented by the COleControl class. The COleControl class contains predefined member functions that support the common properties of a control. Some common properties include the caption of the control, as well as the foreground and background colors.The action to add a common property is to open the Library node in Class View, in this case the Activexdemo1lib node. Select the second node, the
Original link: contrastive Learning for Image captioning Introduction
The contrastive Learning (CL) proposed in this paper is mainly to solve the problem of caption lack distinctiveness generated in Image caption task.
The distinctiveness here can be understood as uniqueness, meaning that for different pictures, their caption should also be unique and easy to dis
What I wroteCodeIt's much better than the book.
Analysis: to reduce the randomness of input and question content, the operands and operators use random functions.RNDProduced.
