WinForm gets a collection of methods for the current path of the application, as follows, which is worth collectingGets the full path of the current process, including the file name (process name).String str = this. GetType ().

We know that many programmers abroad work in Linux/UNIX environments, so there are many excellent C/C ++ language code that cannot be compiled directly on the Windows platform. In many cases, we can only use tools such as msys and cmake to compile a

// Const modifies the variable and treats the variable as a constant. It can only be read but not written. // The const modifier is immutable. Const Int* P = &;// Const modifier * P. The pointer Variable P cannot be used to modify the content

This section briefly introduces the differences between Boolean and bool: 1. bool is the basic value type, and Boolean is the object. 2. bool is the alias of Boolean, bool is in C #, and Boolean is in. NET Framework. The relation between bool and

I will summarize the following four parts: 1. placeholder size issues. 2. bytes alignment. 3. Special reserved bits are 0. 4. This struct is stored in the memory. # Include # include # include // basic concepts/* struct _ m {(1) type parameter

Notifyicon is the system tray control. icons in the notification area are shortcuts for some processes that run in the computer background, such as anti-virus programs or volume control. These processes do not have their own user interfaces..

The udpclient class provides some simple methods for sending and receiving unconnected UDP datagram packets in the blocking synchronous mode. Because UDP has no connection transmission protocol, you do not need to establish a remote host connection

Note: The base type of the enumeration type is any integer except char, so the enumerated value is an integer value. Enum provides some practical static methods: (1) method for comparing enumeration instances (2) method of converting the Instance

1. foreach vs for statement Foreach has better execution efficiency thanThe average time spent by foreach is only 30% of that of for. When both for and foreach can be used through the test results, we recommend using a more efficient foreach.In

Core content: Three object-oriented features: encapsulation, inheritance, and Polymorphism Access Level: it is useful to control where members can access it, so as to achieve object-oriented encapsulation. Common level:Public (accessible anywhere)

In the course of learning, I solved the long-standing problem. Let's share with you and discuss it. Similarities between I ++ and ++ I: Example: 1). Int I = 1; I ++; console. writeline (I ); 2). Int I = 1; ++ I; console. writeline (I ); By compiling
