为什么我的菜单建立失败呢？（Win32）

[dreamzll]

程序出来后只有一个空的页面，不见菜单(菜单在"App.rc"里绘制),高手请帮忙看一下哦

#include <windows.h>
#include "resource.h"

LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);

TCHAR szAppName[] = TEXT("App");

DWORD test = 0;

int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPreInstance,PSTR szCmdLine,int iCmdShow)
{
HWND hwnd;
MSG msg;
WNDCLASS wndclass;

wndclass.style = CS_HREDRAW|CS_VREDRAW;
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 = szAppName;
wndclass.lpszClassName = szAppName;

if (!RegisterClass(&wndclass))
{
//test = ::GetLastError();
MessageBox(NULL,TEXT("This programe requires Windows NT!"),szAppName,MB_ICONERROR);
return 0;
}


hwnd = CreateWindow(szAppName,TEXT("App"),WS_OVERLAPPEDWINDOW,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,NULL,NULL,hInstance,NULL);


ShowWindow (hwnd, iCmdShow) ;
UpdateWindow(hwnd);

while (GetMessage(&msg,NULL,0,0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return 0;
}

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

HMENU hMenu;

switch(message)
{
case WM_COMMAND:
hMenu=GetMenu(hwnd);

switch(LOWORD(wParam))
{
case IDM_CLOSE:
MessageBox(hwnd,TEXT("Hello"),szAppName,MB_OK|MB_ICONINFORMATION);
return 0;
case IDM_ABOUT:
MessageBeep(0);
return 0;
}
break;

case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return DefWindowProc(hwnd,message,wParam,lParam);
}

wndclass.lpszMenuName = szAppName; //这里

把菜单的 ID 改为 "App"

注意，要加引号。

[dreamzll]

改过了，还是不行哦....

看如下的代码：

HMENU hMenu;
hMenu = LoadMenu(hInstance,MAKEINTRESOURCE(IDR_MENU));

hwnd = CreateWindow(szAppName,TEXT("Menu Demonstration"),
WS_OVERLAPPEDWINDOW,
100,100,
300,300,
NULL,hMenu,hInstance,NULL);

说明：IDR_MENU 是菜单的 ID
