C # A 32-bit program operates a 64-bit registry,
1 RegistryKey localKey = RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine, RegistryView.Registry64); 2 try 3 { 4 localKey = localKey.OpenSubKey( 5 @"SOFTWARE\Macromedia", true); 6 if (localKey != null) 7 { 8 localKey.DeleteSubKeyTree("FlashPlayer"); 9 10 }11 }
In the C language, what is the symbol (->) and how to use it?
This is a symbol in the struct pointer. Write a program to explain it, for example:
# Include <stdio. h>
Struct STU // define a struct
{
Int num;
} Stu;
Int main ()
{
Struct STU * p; // defines a struct pointer.
P = stu; // p points to the struct variable stu.
Stu. num = 100; // attaches an initial value to the struct member num.
Printf ("% d", p-> num); // output the num value in stu
Return;
}
As you can see, the-> method is to reference the variable in the struct !!
Format: p-> struct member (such as p-> num)
The function is equivalent to stu. num or (* p). num.
I don't know. You don't understand, and don't understand call me. O (∩ _ ∩) O ~
Hope to adopt it.
