duilib duilib introductory tutorial simple tutorial 3. The first Hello World program

Little friends can not wait yet, take a look at it Hello World: A new space win32 project, create a main.cpp file, copy the following code into it:

1. #include <windows.h>
2. #include <tchar.h>
4. int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)
5. {
6.     ::MessageBox(NULL, _T("Hello World !"), NULL, NULL);
7.     return 0;
8. }

Copy the code

    Run to see the following results:
     

    Hey, this is not a win32 program it, you fooled me kid?
    ~ O (∩_∩) O ~ This is Alberl want to say: duilib just a win32-based UI library only, not with the duilib later, it is not a win32 program.
Ask how many small partners Gato plate, add program icons and so on, you may feel duilib should provide as many as MFC classes packaged in the group; or feel duilib achieve functional tray; or feel duilib completely replace the win32 and MFC . So here under Alberl reminder: duilib did not like the MFC did all the things the whole package, it just wraps the UI part of it, others still need to use win32, MFC's knowledge, so in addition to the UI part, the other and duilib wood relationship, small partners to directly search the keyword windows on the line.
    Again: the duilib as a class library with, rather than a language, IDE, framework ~ (^ o ^) / ~

    Let's take a look at duilib of Hello World.

    A Hello World is complete, it is not very simple ^ _ ^
    PS: In addition to the above code displays the text beyond, has the following characteristics:
    1, the mouse moves over the client area (the green part), the mouse turns into a hand-type style
    2, when the window is resized and maximized, Hello World will be adaptive window size, it has been centered
    3, if you want to change the background color, then a direct call SetBkColor on the line, is not better than win32 and MFC easy to do ~ (^ o ^ ) / ~
