c語言怎么創建一個窗口篇一

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.創建窗口createwindow

4.顯示窗口和更新窗口

復制代碼 代碼如下:

showwindow (hwnd, icmdshow) ;

updatewindow (hwnd) ;

5.消息循環

復制代碼 代碼如下:

while (getmessage (&msg, null, 0, 0))

{

translatemessage (&msg) ;

dispatchmessage (&msg) ;

}

完整代碼：

復制代碼 代碼如下:

#include

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;

= cs_hredraw | cs_vredraw;

xtra = 0;

xtra = 0;

dproc = myproc;

nce = hinstance;

= loadicon(null,idi_application);

r = loadcursor(null,idc_arrow);

kground= (hbrush)getstockobject(white_brush);

nuname = null;

assname= 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 ;

}

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);

}
