executed using the statement object, we need to deal with some formatting problems. For example, if we want to create an SQL command that inserts the name O ' Reilly into the table, you must replace the "'" Number in O ' Reilly with a two-connected "" number. The best way to do this is to create a helper method that completes the substitution operation, and then use the helper method that is created when t

visualization, you can edit code and visual design in the same window in DW4, which greatly improves the efficiency of web design. However, the editing state can be divided into two types in DW4, one is the source code edit State, the other is the visual editing state. Either way, if you make a change to one of these, it can be immediately reflected to another. Instead of switching between the two states. You can combine these two states in a single window, and of course you can put them in a w

I've always thought that to write Web programs, you have to understand the HTTP protocol, and from my own experience, after you know the HTTP protocol, the APIs that involve Web programming in J2ee,.net are clear, why, because network protocols are the cornerstone of all web-based systems, As long as there are features in the network protocol that will be reflected in the API, here are 3 good books for learning the HTTP protocol: 1.O ' Reilly-http Po
