C + + Learning (ii) Visual Studio writes the system statement to generate an executable file

System command

1, first introduce some system commands

Windows+tab//Toggle Window

Windows+r//Bring up the command window

Command:

Enter Calc to turn on your computer

Enter CMD to open the command window

Enter MSPaint to open paint

System is a function used to run external programs

Format system ("command statement");

You need to add a header file to the code before #include <stdio.h>

(1) Shutdown command

Shutdown-s//Shutdown

Shutdown-a//Cancel shutdown

Shutdown-s-T 60//Timer shutdown 60 seconds after the shutdown time can be self-modifying

SHUTDOWN-R//Logoff computer

At 20:00 shutdown-s//During eight o'clock in the afternoon full timer time can be changed

Slidetshutdown//win10 Available

(2) Color

color+ Color

0-9 a-f

Color/? cmd command view color settings default console foreground and background color

0 = Black 8 = Gray
1 = Blue 9 = light Blue
2 = green A = Light Green
3 = light green B = Light Green
4 = Red C = Light Red
5 = Purple D = Lavender
6 = Yellow E = Light Yellow
7 = White F = Bright White

Color//color+ two digits in front of the back of the background color of the representation font

(3) Pause pauses will display press any key to continue

(4) CLS Clear screen

(5) Generate EXE file

Generate EXE files when you are sure that the code is not a problem

1, change the debug to release 2, the project Property code generation change Run library MT

Find the EXE under the Release folder.

(6) Related solutions

Solution-One solution can have multiple projects a project a program needs to run that project to set which project is the startup item

(7) Related code, project

1. Send code. c/.cpp File

2. Project-----Send the entire project folder

(8) About RC file

RC files are rescourse files (resource files)

(9)

F5 Start Debugging--Mister into an EXE run with error will prompt and build failed

Ctrl+f5 Direct start do not debug if there is error vs will direct error

*************************************************************************************************************** *********

Formally start creating projects, writing Programs

Create a new project first

Select the WIN32 console application

own one of its project names

The address is random, but it will be useful after you write it down.

Click OK

Then click Next

Select an empty Project

Remove the precompiled header and Security development lifecycle

Then click Finish

When you are done, click Solution Explorer on the left

Select the header file right-click

Click Add New Item

Then select the C + + file

Change the name to. C file

Then click Add

Start writing code below

Code

Press F5 to execute after the code is written.

Results

Now we're going to edit it into an EXE file.

First change debug (debug mode) to release (release mode)

Then open Solution Explorer

Select the system command, right-click the properties

Find C + + in properties

Select Code Generation

Select Run Library

Change to MT

Click OK

Then click Regenerate Solution

Then select the System command right-click

Click Open file in File Explorer

Select upper Level

Open the release file

This is the exe file we generated.

Just open it and you can run it.

And now we look at this icon is not nice then we can add a

Add the following methods

Search for ICO on Baidu

Feel free to open a link

Upload a picture yourself to generate an ICO file

Put it in the source code directory (in fact, just remember the address can be, all the same)

Then open Solution Explorer

Select Resource File

Right-click

Add to

Resources

Select icon to click Import

Find our previously generated ICO file to add in

The picture feels empty, no tube

And then rebuild the scenario, you can.

That's the final effect.

The main lessons of this study are:

1: Header file #include <stdlib.h> for System (""); The use of functions

2: Some system commands

3: Generate EXE file in VS

4: Add an icon to the EXE file

In fact, the person can write a shut down the computer EXE program, make good to students or friends, they open a run, the computer directly shut down (of course, this is not a good try, be careful to be friends killed Hee ~)

Well, this time vs study is here.

Please look forward to the next update ~
