the exception and prompts the user that we can catch the error by adding SEH capture code where the decoding function is invoked, so that the program can ignore the error and continue executing.Later facts also proved that the omission of this error has no obvious effect on the program. How to write this capture code, the operating system supports the Seh capture
In the desktop video conferencing, videophone and other multimedia applications, access to digital video is a key prerequisite. Capturing digital video is an extremely complex task before the advent of Videoforwindows (VFW). Microsoft's visualc++ has been supporting Videoforwindows (VFW for short) since version 4.0, which makes video capture programming much easier. With regard to multimedia application development, the most popular information in the

The DOM Event standard defines two event streams, which are significantly different and may have a considerable impact on your application. The two event streams are capture and bubble. Like many Web technologies, before they become standards, Netscape and Microsoft implement them differently. The following describes the DOM Event stage and the sequence of event capture and event bubbling execution as the s

IOS network packet capture method
During iOS development, various network access problems often occur. In the past, packet capture tools were not used, and many network problems were solved. Now, we have finished. This article provides two methods for packet capture:
1. Network Sharing + visual

There are two types of capture groups:One is a common capturing group. If there is no ambiguity, it is referred to as a capturing group. syntax rules: (expression); the other is a naming capturing group. syntax rules :(? 1. Numbering rulesIf you do not explicitly name a capture group, that is, you do not use a named capture group, you must access all
I have a program to capture the picture and package it into a zip file.
Currently, a single thread is used because it is too slow. So I want to use multiple threads for concurrent capturing.
However, I don't know when to package a zip file.
Could you give me some advice?

Write the disk only after it is captured.You maintain a target list in the program. when all the objects in the list exist, you can package them.
We have learned how Visual Basic, Delphi, and other languages can capture screen images. So how does C # implement this function? This article will discuss this issue.

Although proficient in jquery, but not very familiar with its prototype javascript, recently encountered some difficulties in learning javascript, such as bubble and capture, many times mentioned, but I do not know where the application is. I have found some good articles to explain and share them with you.

Python implements parallel capturing of 0.4 million house price data for the entire site (can be changed to capture the city), python captures
Preface
This crawler crawls house price information to practice data processing and whole-site crawling over 0.1 million.
The most intuitive way to increase the data volume is to increase the functional logic requirements. For Python features, carefully select the data structure. In the past, even if the logic

Introduction
Packet Capture needs generally come from filtering, conversion protocol, and packet capture analysis.Filters have many applications, typically packet filter firewall.The application of the conversion protocol is limited to some specific environments. For example, if a thi
Thoughts on Exception Handling
Java has two types of exceptions. I. Check exceptions. Ii. Non-checkable exceptions (runtime exceptions)
The difference between the two: Check exceptions must be explicitly try-catch or throw. You do not need to capture runtime exceptions.
There is no need for much discussion about checked exceptions because they must be captured (during design exceptions ). This article mainly discusses how to throw and
