菜單可能是Windows程式提供的一緻的使用者界面中最重要的部分，而想程式中添加菜單是Windows程式設計中相對容易的布馮。當使用者選擇菜單單選時，Windows向你的程式發送了一個含有才菜單單選ID的WM_COMMAND消息
LOWORD(wParam)
控件ＩＤ
HIWORD(wParam)
通知碼
lParam
子視窗句柄
建立菜單有三種方法；
１用WNDCLASS定義
[cpp] view plaincopyprint?
wndclass.lpszMenuName=szAppName;//I don't konw what the fucking is?在VC++6.0和VS2008竟然不顯示
2使用LoadMenu擷取hMenu,然後在CreateWindow倒數第三個參數寫上hMenu
hMenu=LoadMenu(hInstance,TEXT("MyMenu"));
hwnd=CreateWindow(//倒數第三個參數hMenu)
3第三種方法和第二種方法一樣:
hMenu=LoadMenu(hInstance,MAKEINTRESOURCE(MENUID));
hwnd=CreateWindow(//倒數第三個參數hMenu);
具體步驟跟建立自己的ICON差不多；
1建立Windows32項目，編寫好自己的.cpp檔案
2在項目名稱那裡右鍵添加資源(.rc)，然後resource.h頭檔案也會自己建立
3在Resource檔案夾右鍵，添加資源(Menu)
4然後在圖形界面裡面編輯選項和ID，重命名就行了
5運作
下面看一段簡單的程式：
#include<windows.h>
#include"resource.h"
LRESULT CALLBACK WindowProc(
HWND hwnd, // handle to window
UINT uMsg, // message identifier
WPARAM wParam, // first message parameter
LPARAM lParam // second message parameter
);
int WINAPI WinMain(
HINSTANCE hInstance, // handle to current instance
HINSTANCE hPrevInstance, // handle to previous instance
LPSTR lpCmdLine, // command line
int nCmdShow // show state
)
{
static TCHAR szAppName[]=TEXT("MENUDEMO");
HWND hwnd;
WNDCLASS wndclass;
MSG msg;
HMENU hMenu;
wndclass.cbClsExtra=0;
wndclass.cbWndExtra=0;
wndclass.hbrBackground=(HBRUSH)GetStockObject(WHITE_BRUSH);
wndclass.hCursor=LoadCursor(NULL,IDC_ARROW);
wndclass.hIcon=LoadIcon(NULL,IDI_ERROR);
wndclass.hInstance=hInstance;
wndclass.lpfnWndProc=WindowProc;
wndclass.lpszClassName=szAppName;
wndclass.lpszMenuName=NULL;
wndclass.style=CS_HREDRAW|CS_VREDRAW;
if(!RegisterClass(&wndclass))
{
MessageBox(NULL,TEXT("the program require the window nt"),TEXT("TIPS "),MB_ICONERROR);
return 0;
}
hMenu=LoadMenu(hInstance,MAKEINTRESOURCE(MENUDEMO));
hwnd=CreateWindow(
szAppName, // registered class name
TEXT("this is title"), // window name
WS_OVERLAPPEDWINDOW, // window style
CW_USEDEFAULT, // horizontal position of window
CW_USEDEFAULT, // vertical position of window
CW_USEDEFAULT, // window width
CW_USEDEFAULT, // window height
NULL, // handle to parent or owner window
hMenu, // menu handle or child identifier
hInstance, // handle to application instance
NULL // window-creation data
//SetMenu(hwnd,hMenu);
ShowWindow(hwnd,nCmdShow);
UpdateWindow(hwnd);
while(GetMessage(&msg,NULL,0,0))
TranslateMessage(&msg);
DispatchMessage(&msg);
return msg.wParam;
}
HDC hdc;
PAINTSTRUCT ps;
RECT rect;
switch(uMsg)
case WM_CREATE:
case WM_PAINT:
GetClientRect(hwnd,&rect);
hdc=BeginPaint(hwnd,&ps);
EndPaint(hwnd,&ps);
case WM_COMMAND:
switch(LOWORD(wParam))
{
case ID_FILE_NEW:
MessageBox(NULL,TEXT("你選擇了new"),TEXT("提示"),MB_OK);
break;
case ID_FILE_EXIT:
MessageBeep(MB_ICONEXCLAMATION);
SendMessage(hwnd,WM_CLOSE,0,0);
case ID_FILE_OPEN:
MessageBox(NULL,TEXT("你選擇了Open"),TEXT("提示"),MB_OK);
case ID_FILE_SAVE:
MessageBox(NULL,TEXT("你選擇了Save"),TEXT("提示"),MB_OK);
case ID_FILE_SAVEAS:
MessageBox(NULL,TEXT("你選擇了Save_As"),TEXT("提示"),MB_OK);
}
case WM_DESTROY:
PostQuitMessage(0);
return DefWindowProc(hwnd,uMsg,wParam,lParam);
效果如下
還有一段：
