Error
The earlier part of this chapter shows some of the issues, including how errors occur, how to find errors, how to handle errors, and so on. It is more important now to master the different kinds of errors that can occur and how to distinguish them. The thing to remember is that if you know where to look and what to look for, debugging is easier. At the end of this chapter, you will describe how errors are caught when an
Recently, I knocked on a small exercise project, the student information management system, which encountered some problems during the debugging process. Through these questions, I learned a lot of new knowledge, today, I want to record the "real-time error '123456'". I believe most people will encounter this problem when they first use VB to connect to the database. How to solve the real-

Summary:This article outlines the use of UDDI at run time, discussing the infrastructure of UDDI (provided by the public Registry and UDDI Services in Microsoft Windows. NET Server) as a WEB service to support client applications.

forwarding mechanismDue to the dynamic nature of the objective-c, it is not possible to send an error message to the class at compile time, because the method can continue to be added to the class during the run time, so the compilation period is not known to be implemented in the class in the end.
