The package reprinted to the http://www.cnblogs.com/rchen/archive/2005/09/07/231885.htmlDelphi is divided into four types:
1. runtime package
2. design package
3. runtime and design-time packages
4. Neither runtime nor design-time package
In the process of learning Word2007 tables earlier, the most commonly used features should be the Layout tab in the Table Tools ribbon, which not only allows you to insert and delete rows and columns, but also to set the size of rows and columns.

When the video stream is pushed, the rtmp will have a delay of 3 seconds. At present, one solution is to resolve it in a Mpegts format. If you consider using FFmpeg to push the flow, you can use the HTTP format and UDP format to push the
OCS client distribution can be implemented in two ways:
1 Deployment Tool Install OCS Inventory NG Agent Deployment Tool
2 Packaging tools Ocspackager with ad for distribution

The code above uses the rb_idtoindex message to convert a zone ID into a zone index for commandbands_getrestoreinformation. The data in the structure is usually stored in the system registry. I will explain how to read and write the registry data in Chapter 3 "files and registries.
When the application recovers, it should read the recovery information from the registry and use it when creating commands with controls.// Restore configuration to a command band.Commandb
competition problems by using multithreaded development. Furthermore, if too many system resources are locked, the systematic performance of the GUI will have a negative impact. As a result, swing has been developed into a single-threaded programming model based on event queues. The events on the GUI are executed sequentially on the "event-distributing thread", and there is no contention for resources on the event. Java.awt.EventQueue class, you perf
Using SwingWorker Threading Mode
It is important for swing developers to use the concurrency mechanism with care. A good swing program uses the concurrency mechanism to create a user interface that does not lose its response-regardless of the user interaction, the program can always respond to it. To create a responsive program, developers must learn how to use multithreading in the swing framework.A swing developer will deal with the following types of threads:(1) Initial threads (initial thre
The Security Swing API is designed to be powerful, flexible, and easy to use. In particular, we want to make it easy for programmers to create new swing components, either from scratch or by extending some of the components we provide.
For this purpose, we do not require swing components to support multithreaded access. Instead, we send the request to the component and execute the request on a single thread.
This article discusses threads and swing components. The goal is not only to help you

So that this ternary group can best describe the law of a phenomenon we see.We use Forward-backward algorithm to solve the problems that often arise in reality-the situation that the transfer matrix and the confusion matrix cannot be directly obtained.Summarize three kinds of problems that HMM can solve
