If you don't want to pollute your source code (after all this warning presents only with Microsoft compiler), add <code>_CRT_SECURE_NO_WARNINGS</code> symbol to your project settings via "Project"->"Properties"->"Configuration properties"->"C/C++"->"Preprocessor"->"Preprocessor definitions".

Also you can define it just before you include a header file which generates this warning.
You should add something like this

<pre><code>#ifdef _MSC_VER
#define _CRT_SECURE_NO_WARNINGS
#endif
</code></pre>

And just a small remark, make sure you understand what this warning stands for, and maybe, if you don't intend to use other compilers than MSVC, consider using safer version of functions i.e. strcpy_s instead of strcpy.

blocks|key|1532887|text|您可以使用以下命令在出现警告的位置临时禁用警告|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1532888|#pragma+warning(push)

You could disable the warnings temporarily in places where they appear by using

<pre><code>#pragma warning(push)
#pragma warning(disable: warning-code) //4996 for _CRT_SECURE_NO_WARNINGS equivalent
// deprecated code here
#pragma warning(pop)
</code></pre>

so you don't disable all warnings, which can be harmful at times.

i work on a multi platform project, so i can't use _s function and i don't want pollute my code with visual studio specific code. 
my solution is disable the warning 4996 on the visual studio project. go to Project -> Properties -> Configuration properties -> C/C++ -> Advanced -> Disable specific warning add the value 4996. 
 if you use also the mfc and/or atl library (not my case) define before include mfc _AFX_SECURE_NO_DEPRECATE and before include atl _ATL_SECURE_NO_DEPRECATE. 
 i use this solution across visual studio 2003 and 2005.

p.s. if you use only visual studio the secure template overloads could be a good solution.

blocks|key|1747734|text|您也可以使用Secure+Template+Overloads，它们将帮助您在任何可以轻松推断缓冲区大小(静态数组)的地方将不安全的调用替换为安全的调用。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1747735|只需添加以下内容：|1747736|#define+_CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES+1+|code-block|syntax|javascript|1747737|然后使用_s函数手动修复其余的警告。|1747738|entityMap|0|LINK|mutability|MUTABLE|url|https://msdn.microsoft.com/en-us/library/ms175759(v=vs.140).aspx)^0|6|P|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@$A|V|B|W|1|X]]|C|$]]|$1|D|3|E|5|6|7|Y|8|@]|9|@]|C|$]]|$1|F|3|G|5|H|7|Z|8|@]|9|@]|C|$I|J]]|$1|K|3|L|5|6|7|10|8|@]|9|@]|C|$]]|$1|M|3|-4|5|6|7|11|8|@]|9|@]|C|$]]]|N|$O|$5|P|Q|R|C|$S|T]]]]

You can also use the <a href="https://msdn.microsoft.com/en-us/library/ms175759(v=vs.140).aspx" rel="nofollow noreferrer">Secure Template Overloads</a>, they will help you replace the unsecure calls with secure ones anywhere it is possible to easily deduce buffer size (static arrays).

Just add the following:

<pre><code>#define _CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES 1 
</code></pre>

Then fix the remaining warnings by hand, by using the _s functions.

Combination of @[macbirdie] and @[Adrian Borchardt] answer. Which proves to be very useful in production environment (not messing up previously existing warning, especially during cross-platform compile)

<pre><code>#if (_MSC_VER &gt;= 1400) // Check MSC version
#pragma warning(push)
#pragma warning(disable: 4996) // Disable deprecation
#endif 
//... // ...
strcat(base, cat); // Sample depreciated code
//... // ...
#if (_MSC_VER &gt;= 1400) // Check MSC version
#pragma warning(pop) // Renable previous depreciations
#endif
</code></pre>

blocks|key|1532991|text|对于warning+by+warning案例，明智的做法是在某个时刻将其恢复为默认值，因为您是在逐个案例的基础上执行此操作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1532992|#pragma+warning(disable:+4996)+/*+Disable+deprecation+*/
//+Code+that+causes+it+goes+here

For the warning by warning case, It's wise to restore it to default at some point, since you are doing it on a case by case basis.

<pre><code>#pragma warning(disable: 4996) /* Disable deprecation */
// Code that causes it goes here
#pragma warning(default: 4996) /* Restore default */
</code></pre>

blocks|key|1747887|text|最好的方法是通过简单的检查和评估。我通常这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1747888|#ifndef+_DEPRECATION_DISABLE+++/*+One+time+only+*/
#define+_DEPRECATION_DISABLE+++/*+Disable+deprecation+true+*/

The best way to do this is by a simple check and assess. I usually do something like this:

<pre><code>#ifndef _DEPRECATION_DISABLE /* One time only */
#define _DEPRECATION_DISABLE /* Disable deprecation true */
#if (_MSC_VER &gt;= 1400) /* Check version */
#pragma warning(disable: 4996) /* Disable deprecation */
#endif /* #if defined(NMEA_WIN) &amp;&amp; (_MSC_VER &gt;= 1400) */
#endif /* #ifndef _DEPRECATION_DISABLE */
</code></pre>

All that is really required is the following: 

<pre><code>#pragma warning(disable: 4996)
</code></pre>

Hasn't failed me yet; Hope this helps

blocks|key|1533077|text|您可以禁用安全检查。去|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1533078|Project+->属性->配置属性->+C/C%2B%2B+->代码生成->安全检查|1533079|并选择禁用安全检查(/GS-)|1533080|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

 #pragma warning( disable : 4996 6386 )
 return (wchar_t *)memcpy(_S1, _S2, _N*sizeof(wchar_t));

What is the best way to disable the warnings generated via <code>_CRT_SECURE_NO_DEPRECATE</code> that allows them to be reinstated with ease and will work across Visual Studio versions?
