自动化应用程序经常被编译为本机代码，因此执行速度比VBA代码快。
Automation applications are often compiled to native code and therefore execute faster than VBA code.
然而，解释url的方法及在本机代码的映射对于不同的平台来说是不同的。
However, the way that URLs are interpreted and mapped in the native code differs between platforms.
在本机代码应用程序中，可以向上或向下翻页，但不能随便滚动。
In native code applications, you can page up or down, but cannot scroll about freely.
不要认为自己必须是一名本机代码或JNI专家，或者必须知道每个操作系统。
Don't think that you need to be an expert in native code or JNI or must know every OS.
本机代码可能尝试访问具有无效输入(如过时的本地引用)或编码错误的对象。
Native code may attempt to access an object that has invalid input (such as a stale local reference) or that is coded incorrectly.
将本机代码封装成Web服务是一个优秀的解决方案，这样可以提供许多的好处。
Wrapping the native code as a web service is an excellent solution that offers many benefits. For example.
还需要什么被称为EE举办，这意味着本机代码必须执行引擎和主机的负载。
What would be required is known as EE Hosting, meaning that native code would have to load and host the execution engine.
不过，JVM与本机代码之间的通信通常很慢，因此，太多的JNI调用可能会降低性能。
However, communication between JVM and native code is generally slow, thus too many JNI calls can degrade performance.
通过使用这些方法访问较大的数组，您可以确保只复制本机代码将要实际使用的数组部分。
By using these methods to access larger arrays, you can ensure that you copy only the region of the array that the native will actually use.
基本上你要创建某种形式的代理执行，运行，并通过IPC本机代码将调用它。
Basically you'd have to create some sort of proxy executable that would have to run, and the native code would call it via IPC.
只是没有办法本机代码调用托管代码，除非托管代码运行第一，在一个管理过程。
There's simply no way to get native code to call managed code unless managed code was run first, in a managed process.
随着时间的流逝，Hotspot和JIT会根据收集的信息将解释型代码转化为本机代码。
Over time Hotspot and the JIT will convert the interpreted code into native code using profiling information.
它在应用程序运行之前而不是在应用程序运行过程中执行从MSIL到本机代码的转换。
It performs the conversion from MSIL to native code before running the application instead of while the application is running.
您是否曾经想知道哪个联网接口是可用的，但是在不回复到本机代码的情况下又不知道该如何询问呢？
Have you ever wanted to know which networking interfaces were available, but didn't know how to ask without reverting to native code?
因此，对于JNI 来说，本机代码从传递进来的对象中访问大量单独字段时会导致性能降低。
For JNI, therefore, causing the natives to reach for many individual fields from the objects passed to them leads to poorer performance.
