I. Use of stringsLet wisewords = "\" I am a handsome\ "-boy" var emptystring = "" If Emptystring.isempty{println ("This is a null value")}Simple explanation: The IsEmpty method is used to determine whether a string is null, and then executes the println method in the If statement, because Emptystring is an empty string.Note: There are two ways to create an empty string, one is as Emptystring = "", and the other is to instantiate an empty string by using the String class var emptyanotherstring =
The hard drive's bad road is divided into two kinds: logical bad way and physical bad way. The logic bad way is the soft bad road, mostly is the software operation and the use
Improper cause, can use the software to repair; the physical bad way is the true physical bad way, it indicates the hard disk's surface track
caused physical damage, most of which can not be repaired by software, only by changing the hard disk partition or the use of sector to

(Iid_iwebbrowserapp, Iid_iwebbrowser2, (void * *) iwb2));
In all of these examples, Sid_swebbrowserapp are service flags, but you can often see code that takes Iid_iwebbrowserapp as a service ID. Both usages can work because there is a macro definition in the file:
#defines Sid_swebbrowserapp Iid_iwebbrowserapp
But from a programmatic point of view, Sid_swebbrowserapp is technically more correct and clearer to the person who reads the code.
Also, if you have the courage to implement a huge
