Your event handler will be called when the image - loading operation is complete , and your event handler can examine the 图像加载操作完成时，将会调用您的事件处理程序，您的事件处理程序可以检查
This method discards modifications to data since the last save or load operation if both of the following conditions are met 如果满足下面的两个条件，此方法将会丢弃自上次保存或加载操作之后对数据的修改：
Component classes must exist within an appropriate package ( this is necessary for runtime code transformation and class reloading to operate ) 组件类必须存在于适当的包内（这是对于运行时代码转换和类加载操作必须的） 。
Manages project persistence and stores and retrieves code and other items using save and load operations implemented by the host 对项目持久性进行管理，并对使用由宿主实现的保存和加载操作的代码和其他项进行存储和检索。
Specifies that a bulk update table - level lock is acquired for the duration of the bulk load operation ; otherwise , a row - level lock is acquired 指定在大容量加载操作期间获取大容量更新表级别的锁；否则，获取行级别的锁。
This causes an unnecessary reload of navigation data because the asp . net site navigation features depend on file notifications to keep navigation data up to date 因为asp . net站点导航功能依赖于文件通知来保持导航数据最新，所以这会引起不必要的导航数据重新加载操作。
Heap - optimized bulkload operations with concurrent scan , under these isolation levels : snapshot , read uncommitted , and read committed using row versioning Hobt . bulk _ operation下列隔离级别下的优化堆大容量加载操作与并发扫描：快照、未提交读和使用行版本控制的已提交读。
If it finds all the libraries it wants but can t find a symbol , it can abort for that too but it may not act until the actual attempt to reference that symbol occurs - this is rare case though because normally , if the symbol isn t there , it will be noticed during the initial link 如果它找到了所有需要的程序库，但却无法找到某个符号，那么它也可能会因此而停止加载操作（但是可能直到真正尝试去引用那个符号时才会发生这种情形）这是一种很少见的情况，因为通常如果不存在某个符号，那么在初始化链接的时候就会被警告。
The primary measures for control precept are : sufficiently and effectively utilizing the the air compressors " interior data , realizing online surveillance and alarming for failure of the the air compressors " running interior parts ; letting the air compressors running by master and slave manner , by reasonable arranging the alignment of the air compressors , making the masters yielding pressed air and the slaves adjusting the pressure of the air . this decreases the times of loading and unloading greatly and the decreased failure of air compressors and low maintain ; at the same time we adopt abundant value of the set pressure for stabling the compressure . the air compressors become loaded or unloaded ahead by the abundant value ; caning unloading control for saving power , when the air compressors get along with unloading for a while , the system will stop them ; consummating the purposes for control , enhancing offline control for over - press and low - press , continual loading control and unloading control 经过分析研究，针对原来存在的问题，在控制方案上主要的改进措施有：充分、有效地利用了空压机的内部参数数据，对空压机的内部部件的运行情况实现了在线监视及故障报警；对空压机采用了主、辅结合的运行方式，通过对空压机加、卸载队列的合理排序，使空压机自动实现主机产气、辅机进行气压调节，减少了空压机的加载和卸载次数；在压缩空气压力的稳定上进行了裕量控制，在压缩空气压力不到供能品质所规定的上、下根就根据一定的裕量提前进行卸载和加载操作；在节约电能方面对空压机进行了卸载停机控制，当空压机在一定时间内一直处于卸载状态，系统就认为该空压机没有运行的必要，自动将其停机；完善了控制效果，增加了超压低压脱网控制、连续加载控制、连续卸载控制等功能。
