industry, however, as soon as a mention of Java, people's nerve cells will be immediately excited, because Sun's Java technology is very hot! First you should understand what people mean by Java. First of all, if you are a beginner, some of the following term will inevitably let you Da Guo.

Preface Today, users expect fast and dynamic applications that can be accessed through the web. This article series shows how to use reverse Ajax (reverse Ajax) technology to develop event-driven Web applications. Part 1 of the series describes reverse Ajax, polling, streaming, Comet, and long polling ). You have learned how comet uses HTTP long polling. This is the best way to reliably implement reverse Ajax, because all existing browsers provide

or by using the device environment's handle HDC, which includes the display height and width, the number of colors supported, and the resolution.GDI-related classes in MFCTo support GDI drawing, MFC provides two important classes: The device context DC, which sets drawing properties and drawing graphics, and a drawing object class that encapsulates a variety of GDI drawing objects, including brushes, brushes, fonts, bitmaps, palettes, and regions.In

only mentioned above. His work is more and more like consulting engineers. Good presales have excellent customer communication skills. Provide customers with a strong sense of technical advantages and trust. At the same time, it can truly discover, understand, and solve customer problems. For example, pre-sales engineers such as Oracle, IBM, Ms, and Huawei have poor technical capabilities, industry knowled

database system, and the database ensures data consistency during concurrent access. Static data can be stored in network file systems such as NFS/CIFS, but the Network File System has limited scalability. Generally, the NFS/CIFS server can only support 3 ~ Six busy server nodes. For large-scale Cluster Systems, you can consider using distributed file systems, such as AFS [1], GFS [2.3], Coda [4], and Inte

in XML? I'm also here to mention that when data is compared It's more appropriate to use XML data for complex random rates, and that's when you're going to read the data on different operating systems. Out. Do not use XML files to store data if you are not in a critical moment or do not support the database's space. 2, easy to read the XML data, txt text is more difficult to operate, we have to read a line of judgment, but also very multi-functional

applications have an intermediate layer, which is used to centrally process application logic. In this way, different customer programs can use the same data and ensure that the data logic is consistent. At the same time, the customer program can be relatively small, because a considerable part of the work is done by the middle layer, which is called a "thin" customer
