The data volume is 5k+. Referring to the function given in the blog, it takes 15s to run once, which is too long. So finally I didn’t choose to traverse data in Mysql, but traversed in the class when the user selects the parent node. The overall time consumption will be much smaller, and it will not bring lag feeling to the user. I don’t use Mysql functions much usually, so I record it for future learning use. After the function is created in Mysql, it will prompt the error message This func...

数据量5k+，参照博客中给出的函数，运行一次需要15s，耗时太长，所以最终没有选择在Mysql中进行数据的遍历，而是采用在用户选取父节点时，在类中遍历，总体耗时会小很多，也不会给用户带来尺钝感。 平时使用Mysql 的函数不多，所以还是记录下来以后学习使用 在Mysql 中函数创建后会提示This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its de 的错误信息，参照博客:MySQL 创建函数报错 This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you might want to use the less safe log_bin_trust_function_creators 解决办法由两个： 在函数体前写一句 set global log_bin_trust_function_creators...

Today when using WCF to pull data from database, reported this error, checked Web.config saw maxReciveMessageSize inside already set to max. Finally by modifying parameter in configuration file in WCF debugger, modifying number to max, reconfiguring can run successfully.Reference Blog:WCF Request Data: Exceeded Maximum Message Size Quota for Incoming Message (65536). To increase quota, please use MaxReceivedMessageSize property on corresponding binding element. If client receiving has proble...

今天使用WCF从数据库拉取数据时，爆出这个错误，查看Web.config看到里面maxReciveMessageSize已经设置为最大，最后通过在WCF调试器中修改配置文件中的参数，将数修改为最大，重新配置后即可运行成功。参考博客:WCF请求数据:已超过传入消息(65536)的最大消息大小配额。若要增加配额，请使用相应绑定元素上的 MaxReceivedMessageSize 属性。 如果时客户端的接收出现问题，只需要去客户端的配置文件将配置容量进行设置即可 12345<bindings> <basicHttpBinding> <binding name="BasicHttpBinding_IMysqlService" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647"/> </basic...

Recently developing family library management. Original idea was to perform hierarchical management of family library through left right interpolation. Later simulated and found that for large number of new project family libraries added later, there will be a lot of burden, so recorded this idea method for people in need.If not involving large batch modification, can use this method. But probably only standard hard coding etc. in the whole housing construction industry can be suitable.Left r...

近期在进行族库管理的开发，原来的想法通过左右插值进行族库的层级管理后来模拟了一下发现对于后期新增大量的项目族库会有不少的负担，所以把这个想方法记录下来，给有需要的人吧。如果不涉及大批量的修改，可以使用这种办法，但是整个房建行业恐怕只有规范硬编码之类的能够适合。左右值比较的关系主要和下图一样详细内容可以看这个博客：左右值编码存储无限分级树形结构设计 下面的示例是，将族库遍历按照左右插值创建树形结构，主要记录的是思路，里面的一些方法是我自己创建的结构计算主要是通过 非最低层级，通过下面的文件总量与左值确定右值 最低层级，通过左值与右值的自减即可确认 12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152 /// 引用i值，并设置左右值 /// </summary> /// <param name="df"></param> /// <param name=&qu...

I used to study C++ for a while, but never found a suitable project to get familiar with it. So I am learning C++ following an open source project on github, address: github 1234567891011121314151617181920212223242526272829303132333435363738394041424344454647/* * Virtual Inheritance * Concept: Solves the data inconsistency problem caused by different copies of the same data member inherited from different paths in memory. * Set the common base class as a virtual base class. * At this time, t...

之前看过一段时间c++，但是一直没有找到合适的项目进行熟悉，所以在跟着github的一个开源项目学习c++,地址为:github 12345678910111213141516171819202122232425262728293031323334353637383940414243444546/* * 虚继承 * 概念：解决从不同途径继承来的同名数据成员在内存中有不同拷贝造成的数据不一致问题，将共同的基类设置为虚基类。 * 这时从不同的路径继承过来的同名数据成员在内存中就只有一个拷贝，同一个函数名也只有一个映射 * 解决问题： * 解决了二义性问题，也节省了内存，避免数据不一致问题 * * 分析： * 从程序中可以看到，C,D,E不同的继承类型为三种 public A,virtual A与virtual B，其中两次使用了virtual B * 第二次的继承将会直接引用第一次的拷贝，所以我们会看到控制台对于C,D部分的输出为B-A-A其中第二次B被省略 * 按照继承的原则首先基类，生成C-D，然后成员为A，最后为E，所以顺序为：B-A-A-C-D-A-E * */# inclu...

在Revit二次开发中，相较于土建模块多出了管道系统模块，每个机电管件与管道之间连接由Connector控制，从而将整个管道系统串联起来如果在LookUp中点开管道可以看到分为ConnectorManagement 与 All Refs两个类，之中都存储了Connector，刚接触的人可能会觉得比较乱 如果从喷淋开始依次查询所有相交管道，我们可以获取每一个Connector的All Refs进入Connector之后获取Owner然后进入相应构件的Management从而获得所有的构件连接器。简单来说All Refs存储的是外部的连接器也就是与管道相连的管件信息，Management存储的本身的Connector会根据设置数量有不同。 如果是末端关键，点击All Refs将会由两个Connector的情况其中一个指向Piping System需要在筛选中进行排除。 1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556575859...

In Revit secondary development, compared to civil engineering module, there is piping system module. Connection between each MEP pipe fitting and pipe is controlled by Connector, thereby connecting the entire piping system in series.If you click pipe in LookUp, you can see it is divided into ConnectorManagement and All Refs two classes, both store Connector. People who just contacted might feel a bit messy. If querying all intersecting pipes sequentially starting from sprinkler, we can get Al...
