Method 1: In the packaging project, locate the "msiexec.exe" file (generally found in c: windowssystem32 (in the system directory ). In the file system view, select the application file, right-click msiexec.exe and choose "create shortcut", and

A farmer raises a cow. After three years, this ox produces one ox every year. After three years, another ox can be born every year ...... How many cows does a farmer have in 10 years? What about n years?Here we will talk about the idea of solving

Because the SDK must be developed based on the Development Kit. Therefore, you must call the SDK development interface of VC in C. And call the dynamic link library DLL file in C. C # There are two methods to call the dynamic link library. One is to

In multithreading, to maintain data consistency, you must lock the data or function that accesses the data. This is common in the database, but most of the programs are single-threaded, therefore, there is no need for locking, but in multithreading,

Set file PropertiesString filePath = @ "d: file ";DirectoryInfo dir = new DirectoryInfo (filePath );FileInfo [] fileInfo = dir. GetFiles ();Foreach (FileInfo file in fileInfo){String fileName = file. FullName;File. SetAttributes (fileName,

Note: I am a C # programmer, but once I had a requirement that I could only use C/C ++ to write, and the data to be read was stored in DB (SQL CE v3, I don't know how to use C/C ++ (the key is to use OleDB to access the database, which is really

The Code is as follows: System. Diagnostics. ProcessStartInfo Info = new System. Diagnostics. ProcessStartInfo ();// Set the external program nameInfo. FileName = "notepad.exe ";// Set the startup sequence of the program to test.txt.Info. Arguments =

As long as the Socket connection is used, Thread is basically used, which is cross-used.C # encapsulation Socket usage is basically not very complicated, but I don't know whether the hosted Socket has any other performance or security issues.The

Recently, the project needs to study the import and export of Execl. This project generates another Execl from the data of one Execl, so I didn't use the database. -- Ps: It seems that Execl is also a database! Region ~  First, import Execl to

In C # learning, it is easy to confuse the use of virtual and abstract methods. Now let's discuss the differences between them. Both of them involve the use of override in a derived class. 1. Virtual Method) Virtual keywords are used to modify

[References: Yan Weimin. Data Structure (c)] Expression evaluation is a basic problem in programming language compilation. Its implementation is a typical example of stack applications. After one day, we have a good algorithm to share with

There are many solutions to perform file read/write operations on the LAN like processing files on the local disk, FTP: the configuration is cumbersome and asynchronous transmission, resulting in complicated response to the results of the

During the winter vacation, I checked the data structure of the C # language description. I just want to be more familiar with computer languages. I want to use computer languages to communicate with computers like my mother tongue. It's strange

First, define three important classes NativeMethods, UnsafeNativeMethods, and Snapshot:NativeMethods. cs:Program code using System;Using System. Collections. Generic;Using System. Text;Using System. Runtime. InteropServices;Using System.

1. _ arglist Let's start with _ arglist. _ Arglist is used to send parameters to methods. We usually pass parameters to the method through the parameter list specified in the function header. If we want to pass a new set of parameters to the method,

Because the program must communicate with the program developed by C ++, the communication data is the converted byte stream of the struct, therefore, C # Must be able to smoothly convert bytes into C # struct.   Define the C # struct
