這篇文章主要介紹了C語言創(chuàng)建windows窗口實(shí)例,本文直接給出實(shí)現(xiàn)代碼,同時(shí)講解了編碼的步驟,需要的朋友可以參考下

耐得住寂寞，禁得起誘惑，這就是程序人生

步驟：
1.在WinMain中定義各種變量
2.注冊窗口類RegisterClass
3.創(chuàng)建窗口CreateWindow
4.顯示窗口和更新窗口

復(fù)制代碼代碼如下:

ShowWindow (hwnd, iCmdShow) ;

     UpdateWindow (hwnd) ;

5.消息循環(huán)

復(fù)制代碼代碼如下:

while (GetMessage (&msg, NULL, 0, 0))

     {

          TranslateMessage (&msg) ;

          DispatchMessage (&msg) ;

     }

完整代碼：

復(fù)制代碼代碼如下:

#include <windows.h>  

LRESULT CALLBACK MyProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam);  

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd )  

{  

     MSG      msg;  

     HWND     hwnd;  

     static TCHAR szAppName[] = "hl";  

     WNDCLASS wndclass;  

     wndclass.style        = CS_HREDRAW | CS_VREDRAW;  

     wndclass.cbClsExtra   = 0;  

     wndclass.cbWndExtra   = 0;  

     wndclass.lpfnWndProc  = MyProc;  

     wndclass.hInstance    = hInstance;  

     wndclass.hIcon        = LoadIcon(NULL,IDI_APPLICATION);  

     wndclass.hCursor      = LoadCursor(NULL,IDC_ARROW);  

     wndclass.hbrBackground= (HBRUSH)GetStockObject(WHITE_BRUSH);  

     wndclass.lpszMenuName = NULL;  

     wndclass.lpszClassName= szAppName;  

     if(!RegisterClass(&wndclass))  

     {  

          MessageBox(NULL,TEXT("error"),TEXT("title"),MB_ICONERROR);  

          return 0;  

     }  

     hwnd = CreateWindow(szAppName,  

                              TEXT("Hello"),  

                              WS_OVERLAPPEDWINDOW,  

                              CW_USEDEFAULT,  

                              CW_USEDEFAULT,  

                              CW_USEDEFAULT,  

                              CW_USEDEFAULT,  

                              NULL,  

                              NULL,  

                              hInstance,  

                              NULL  

                              );  

     ShowWindow(hwnd,nShowCmd);  

     UpdateWindow(hwnd);  

     while(GetMessage(&msg,hwnd,0,0))  

     {  

          TranslateMessage(&msg);  

          DispatchMessage(&msg);  

     }  

     return msg.wParam;  

}  

LRESULT CALLBACK MyProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)  

{  

     switch(message)  

     {  

     case WM_DESTROY:  

          PostQuitMessage(0);  

          return 0;  

     }  

     return DefWindowProc(hwnd,message,wParam,lParam);  

}
