Building application in debug with release CRT with dependency issues on boost

由 泪湿孤枕 提交于 2019-12-24 16:16:10
问题 I am building an application with dependency on boost. My application output is libraries that end up being used by another client application. I recently discovered I was building my application in debug mode using /MDd for code generation (debug CRT libraries) and that the client application was built against release CRT even in debug mode. Hence this can cause some memory heap corruption errors. To confirm, this I tested everything in release mode and there it all works fine. To address

OpenSSL, Converting CRT to PEM

问题 I've been trying to use openssl to convert a .crt certificate to a .pem openssl.exe x509 -in server.crt -out openssl.der -outform DER After using that command, I get unable to load certificate 1760:error:0906D06C:PEM routines:PEM_read_bio:no start line:.\crypto\pem\pem_lib.c:703:Expecting: TRUSTED CERTIFICATE I've tried following https://support.ssl.com/Knowledgebase/Article/View/19/0/der-vs-crt-vs-cer-vs-pem-certificates-and-how-to-convert-them but I'm at a loss and nothing on there is

Using _crtBreakAlloc to find memory leaks - identifier “_crtBreakAlloc” is unidentified

问题 I am trying to use _crtBreakAlloc in the Watch window as suggested in this link, but the value line says that 'identifier "_crtBreakAlloc" is unidentified' and it simply does not work. What am I doing wrong? I'm using Visual Studio by the way. An example of code: #define _CRTDBG_MAP_ALLOC #include <stdlib.h> #include <crtdbg.h> #include <malloc.h> int main() { int *arr = (int*)malloc(10 * sizeof(int)); //breakpoint here free(arr); return 0; } I then write _crtBreakAlloc into the Name field of

When building a DLL; what type of CRT should I link to?

由 有些话、适合烂在心里 提交于 2019-12-22 08:21:04
问题 In windows; there are 2 options to link to a CRT: Multithreaded, static link Multithreaded, dynamic link Can someone shed some light on what is the best practice here? Should I link 'statically' to the CRT or do a dynamic link? If i do a dynamic link, and I write a program that uses my DLL + another 3rd party DLL (which is doing a static link to CRT), is that an issue? 回答1: This is a Big Deal when you use DLLs in your application. It is very important that the EXE and the DLLs use the same

Convert .crt file to .cer and .key

问题 I was asked to help converting a certificate for a renewal. I was given the domainname.crt file along with some intermediate .crt files, but no .key file. They want me to convert the CRT to both a .CER and a .KEY file. I have looked at the following (among many other sites) but they either say I need the .key file, which I don't have, or that I have to install it locally and then export it, but when using MMC and trying to export it the .PFX option is grayed out. http://community.spiceworks

How can fopen_s be more safe than fopen?

由 痞子三分冷 提交于 2019-12-22 01:40:58
问题 I'm working on legacy code for Windows platform. When I compile the code in VS2013 , it give following warning: error C4996: ' fopen ': This function or variable may be unsafe. Consider using fopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details." And it will also give samiliar warning for sprintf . I understand sprintf_s is more safe than sprintf because of buffer overflow. But how can be fopen_s be more safe than fopen , there is no chance of

LCD 时间参数与crt显示器联系

如果将 LCD 显示一帧图像的过程想象成绘画，那么在显示的过程中就是用一根“笔”在不同的像素点画上不同的颜色。这根笔按照从左至右、从上到下的顺序扫描每个像素点，并且在像素画上对应的颜色，当画到最后一个像素点的时候一幅图像就绘制好了。假如一个 LCD 的分辨率为 1024 * 600 LCD 是怎么扫描显示一帧图像的。一帧图像也是由一行一行组成的。 HSYNC 是水平同步信号，也叫做行同步信号，当产生此信号的话就表示开始显示新的一行了，所以此信号都是在图最左边。当 VSYNC 信号是垂直同步信号，也叫做帧同步信号，当产生此信号的话就表示开始显示新的一帧图像了 可以看到有一圈“黑边”，真正有效的显示区域是中间的白色部分。那这一圈“黑边”是什么东西呢？这就要从显示器的“祖先” CRT 显示器开始说起了， CRT 显示器*就是以前很常见的那种大屁股显示器，在 2019 年应该很少见了，如果在农村应该还是可以见到的。CRT 显示器屁股后面是个电子枪，这个电子枪就是我们上面说的“画笔”，电子枪打出的电子撞击到屏幕上的荧光物质使其发光。只要控制电子枪从左到右扫打万一行(也就是扫描一行)，然后从上到下扫描完所有行，这样一帧图像就显示出来了。也就是说，显示一帧图像电子枪是按照‘Z’形在运动，当扫描速度很快的时候看起来就是一幅完成的画面了。 当显示完一行以后会发出 HSYNC 信号，此时电子枪就会关闭

Statically linking against library built with different version of C Runtime Library, ok or bad?

由 安稳与你 提交于 2019-12-21 09:19:00
问题 Consider this scenario: An application links to 3rd party library A. A is built using MSVC 2008 and is statically linking (ie. built with /MT) to the C Runtime Library v9.0. The application is built using MSVC 2005 and is statically linking to A and (using /MT) to the C Runtime Library v8.0. I can see trouble with this - for instance if types are changed in the headers between runtime library versions. Is care taken to keep the runtime library headers compatible between versions, or should
