<windows编程问题>程序没有错误，但是运行后没有任何反映
小弟假期在学习windows编程，书是比较老的一本《windows95/98操作系统编程实例》,第一个窗口程序就出问题了，没有任何的错误，但是点击运行后，没有任何的反应。
如果在建立时选择windows console application编译就会出现错误，选择windows application没有任何编译错误，但是运行没有任何显示。
是不是因为这个全部是c代码的原因？希望能帮忙解决一下，着急。
代码如下：
//WinDemo.c
#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[] = "windows ";
char lpszTitle[] = "windows demo ";

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.hbrBackground = GetStockObject(WHITE_BRUSH);
wndclass.lpszMenuName = NULL;
wndclass.lpszClassName = lpszClassName;

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

hwnd = CreateWindow(
lpszClassName,
lpszTitle,
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hInstance,
NULL
);
ShowWindow(hwnd,nCmdShow);
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;
}




[解决办法]
wndclass 你少初始化了一个

改成就好了

#include "stdafx.h "
#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;
static char lpszClassName[] = "windows ";
char lpszTitle[] = "windows demo ";

wndclass.style = 0;
wndclass.lpfnWndProc = WndProc;
wndclass.cbClsExtra = 0;
wndclass.cbWndExtra = 0;
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 = lpszClassName;

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

hwnd = CreateWindow(
lpszClassName,
lpszTitle,
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hInstance,
NULL
);
ShowWindow(hwnd,nCmdShow);
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);
break;

default:
return DefWindowProc(hwnd,message,wParam,lParam);
}
return 0;
}
