C語(yǔ)言創(chuàng)建windows窗口實(shí)例

 更新時(shí)間：2015年04月23日 10:50:40   投稿：junjie  
這篇文章主要介紹了C語(yǔ)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(cè)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); 
}
