I mentioned the navigation problem in the first article of this series, but some problems may not be understood yet. So I will write another blog about navigation here. There are two problems: 1. Why cannot I directly transfer objects other than simple types when calling the frame. navigate method? 2. Why will the page be initialized every time the page is back? Let me first talk about the vs Projec

For:2 Add: When we rewrite the Hashcode method for a class we write, we may see code like the following, in fact we do not understand why we use such multiplication to generate hash code (hash code), and why this number is a prime, why usually choose 31 this number? The answer to the first two questions you can Baidu, choose 31 is because you can use SHIFT and subtraction operation instead of multiplication, so as to get better performance. You may ha

objects and strings are immutable objects, and all python caches them efficiently, which leads us to think that Python should create new objects without the illusion of creating new objects. Python caches only simple integers, and the range of Python-cached integers changes, so don't use this feature. (I don't know how to use it.)1.3 Boolean typeBoolean type operators have And,or and not three, equivalent to the in C;, | |, and!. Where not is the highest priority, followed by and and OR.

(Reprinted -- keep learning later) According to the information provided in the SDK documentation, this interface seems a bit complicated, including the connection API, descriptionAPI and ManagerThree sets of APIs are also involved in some API applications such as XML parsing. I read its example Program (addressbook under the s60ex directory), which makes me more confused. Why is it different from the usual WebService? In the SDK documentation, there is a description about csenserviceconnection:
