下面代码怎么运行起来没反映？
#include <windows.h>
LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
int WINAPI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevinst,
LPSTR lPszCmdLine,
int nCmdShow)
{
HWND hwnd;
MSG Msg;
WNDCLASS wndclass;
char lpszClassName[] = "´°¿Ú";
char lpszTitle[] = "´°¿Ú";
wndclass.style = 0;
wndclass.lpfnWndProc = WndProc;
wndclass.cbClsExtra = 0;
wndclass.hInstance = hInstance;
wndclass.hIcon = LoadIcon(NULL,IDI_APPLICATION);
wndclass.hCursor = LoadCursor(NULL,IDC_ARROW);
wndclass.hCursor = LoadCursor(NULL,IDC_ARROW);
wndclass.lpszMenuName = NULL;
wndclass.lpszClassName = lpszClassName;

if (!RegisterClass(&wndclass))
{
MessageBeep(0);
return FALSE;
}

hwnd = CreateWindow(lpszClassName,
lpszTitle,
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hInstance,
NULL);
ShowWindow(hwnd,SW_SHOWNORMAL);
UpdateWindow(hwnd);
while(GetMessage(&Msg,NULL,0,0))
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}
LRESULT CALLBACK WndProc(HWND hwnd,
UINT message,
WPARAM wParam,
LPARAM lParam)
{
switch(message)
{
case WM_DESTROY:
PostQuitMessage(0);
default:
return DefWindowProc(hwnd,message,wParam,lParam);}
return(0);
}

少一条初始化的东东.
wndclass.hbrBrush = (HBRUSH)GetStockObject ( WHITE_BRUSH ) ;

[shoyour]

wndclass.hbrBrush = (HBRUSH)GetStockObject ( WHITE_BRUSH ) ;
加上去错误
wndclass.hbrBackground = (HBRUSH)GetStockObject ( WHITE_BRUSH ) ;
加上去也没反映
