Windows开发:WinSDK初始化

一.简介

二.编译流程

对话框编辑器(Dialog Editor)->.DLG文件->集合成.RC文件

图片编辑器(Image Editor)->.BMP/.ICO/.CUR文件->集合成.RC文件

字体编辑器(Font Editor)->.FON文件->集合成.RC文件

.RC文件通过资源编译器(RC Compiler)->.RES文件->链接(LINKER)

 

头文件(.h)+源文件(.c)->通过C语言编译器(C Compiler)->.OBJ文件+动态库(.LIB/C runtime/DLL Import)->链接器(LINKER)

链接器最终生成.EXE文件

三.流程

#include <windows.h>
 
//1.声明回调函数
LONG WINAPI WndProc(HWND,UINT,WPARAM,LPARAM);
 
 
int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpszCmdLine,int nCmdShow){
 
    //2.填充窗口类
    WNDCLASS wc;
    HWND hwnd;
    MSG msg;
 
    wc.style=0;    //Class Style
    wc.lpfnWndProc=(WNDPROC)WndProc;    //Window procedure address
    wc.cbClsExtra=0;    //Class extra bytes
    wc.cbWndExtra=0;    //Window extra bytes
    wc.hInstance=hInstance;    //Instance handle
    wc.hIcon=LoadIcon(NULL,IDC_ARROW);    //Icon handle
    wc.hCursor=LoadCursor(NULL,IDC_ARROW);    //Cursor handle
    wc.hbrBackground=(HBRUSH)(COLOR_WINDOW+1);    //Background handle
    wc.lpszMenuName=NULL;    //Menu name
    wc.lpszClassName="MyWndClass";    //WNDCLASS name
    
 
    //3.注册窗口类
    RegisterClass(&wc);
 
    //4.创建窗口
    hwnd=CreateWindow(
        "MyWndClass",    //WNDCLASS name
        "SDK Application",      //Window title
        WS_OVERLAPPEDWINDOW,    //Window style
        CW_USEDEFAULT,          //Horizontal position
        CW_USEDEFAULT,          //Vertical position
        CW_USEDEFAULT,          //Initial width
        CW_USEDEFAULT,          //Initial height
        HWND_DESKTOP,           //Handle of parent window
        NULL,                   //Menu handle
        hInstance,              //Application's instance handle
        NULL                    //Window-creation data
    );
 
    //5.显示更新窗口
    ShowWindow(hwnd,nCmdShow);
    UpdateWindow(hwnd);
    
    //6.消息循环
    while(GetMessage(&msg,NULL,0,0)){
        TranlateMessage(&msg);
        DispatchMessage(&msg);
    }
 
    return msg.wParam;
 
}
 
//7.实现回调函数处理消息
LPRESULT CALLBACK WndProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam){
    
    PAINTSTRUCT ps;
    HDC hdc;
 
    switch(message){
    
    case WM_PAINT:
        hdc=BeginPaint(hwnd,&ps);
        Ellipse(hdc,0,0,200,100);
        EndPaint(hwnd,&ps);
        return 0;
 
    case WM_DESTROY:
        PostQuitMessage(0);
        return 0;
    }
 
    return DefWindowProc(hwnd,message,wParam,lParam);
 
}
