Let's take a look at the following:Code

}
When the UI thread is busy, the UI will be locked and the progressbar will not be updated. After the while loop ends, it will be updated to 100. If the two lines

Java calls the JavaFX method. These three methods are :1. Use the Scriptenginemanager class. This is the Java Scripting API (scripting API) based on the JSR-223 specification. You can run some scripts in your Java program, such as JavaFX script, JavaScript, and so on.2. Via the JavaFX reflection API. This is the reflection API provided by JavaFX, and almost all of the JavaFX classes can be called.3. First implement a Java interface with the JavaFX class, and then the Java program can

Registering DLLs
In order to invoke the method we wrote, we need to register the DLL we just compiled in SQL Server. We can use the following command in the database to register the DLL (path to the path of your DLL file)

To invoke
1, forname method
Forname is a static method that uses the call to get the class object corresponding to the classes name and to load the class object in.
If you save a class name in a string (such as XML), you can dynamically invoke the load when the program is run.
Note: It is only available if the calling parameter is a class name or a method.
2, Newinstance () method
Role: Instantiate an object. The return type is object. The difference with new i
In C + +, the Const object can only invoke the const member function, for what reason. Let's look at the following examples and analyze them to understand why:

Compile an error: We can see that the compiler complains that the Const Myint cannot be converted to Myint, and that there are some conversion problems when the Const object calls the non-const member function, so let's take a look at the following analysis: The const object canno

In multithreaded programming, we often have to update the interface display in the worker thread, and the method of invoking the interface control directly in multi-threading is the wrong way, and invoke and BeginInvoke are to solve this problem, which makes you display in a secure update interface in multi-thread.The correct approach is to encapsulate the code that involves the update interface in a worker thread as a method, called by
This article mainly introduces the new magic method _ invoke in PHP5.3. For more information, see the new magic method named _ invoke in PHP since version 5.3, by using this method, you can directly call an object after creating an instance. Example:
class testClass{public function __invoke{print "hello world";}}$n = new testClass;$n();
The execution result is:
hello world。
