Windows programming Note (1): Hello world!

Start learning Windows Programming and take note of all your learning notes for later viewing.

The first note, the Hello world! program is relatively simple, on the code:

#include <windows.h>int WINAPI WinMain (hinstance hinstance,hinstance hpreinstance,pstr sizecmdline,int iCmdShow {MessageBox (Null,text ("Hello world!"), TEXT ("MESSAGE"), MB_OK); return 0;}

Here's a quick explanation:

1 Header files:

In a Windows program, include the header file "Windows.h". In addition, there are some common header files, such as: "Winuser.h", "wingui.h".

2 Program Entry:

Windows programs are similar to the entrance to the C program. But from the main () function becomes int WINAPI WinMain (...) This function.

3 Message box functions:

The function of the MessageBox () is to display a message box in the following format:

MessageBox (Null,messageboxtext (content), title (title), MB_OK);

The usage is quite simple, no longer explained.
