C++ is an object-oriented programming language extended by C. In C++ you can also use theWindowscontrol, the dialog box MessageBox is one.
Step one:
Type the program header file #include<>, if you want to do screen output, you need to type the
#include<iostream>
#include<cstdio>
using namespace std;
step Two
Define the main function int main()
Then type the MessageBox function frame.
MessageBox(console program generally NULL can be, "dialog box body", "dialog box title", dialog box style options);.
step Three
"Dialog body" fill in the dialog box after the appearance of the middle of the part, the title to write such as "tips", "welcome" text, the style options above wrote "MB_OK" can be replaced by the number 0. Indicates that the default option in a dialog box without icons is the first button, and there is only one "OK" button.
Here are the full parameters
MB_OK Default. There is an OK.
MB_YESNO has yes and no.
MB_ABORTRETRYIGNORE with abort, retry and skip
MB_YESNOCANCEL with yes, no and cancel
MB_RETRYCANCEL with retry and cancel
MB_OKCANCEL has OK and Cancel.
Step 4
All of these values above can be replaced with numbers starting from 0. Below is the icon information for the dialog box:
(Please put a + sign between values of different types)
16: Forks
32: Question mark
48: exclamation point
64: lowercase i
I don't really want to talk about defaults here, because defaults are only used when you use the keyboard a lot.
The following program is a body for "Baidu Experience", the title is "Welcome" and there are OK to cancel and the fork of the dialog box program
Step Five:
Why do we need so many buttons? Because MessageBox has a return value!
The following is information about the return value of the function:
Determination: 1
Canceled: 2
Waivers: 3
Retries: 4
Skip: 5
Yes: 6
No: 7
You can use if(MessageBox(NULL, "Tap OK to start", "Prompt",MB_OKCANCEL)==1) to determine whether the return value of this message box (that is, the button clicked) is "OK".
step 6
When everything is ready, you can compile and run it! The dialog box in the figure is just a simple dialog box, does not make any sense, if with other code can be composed of a complete program!
