一个简单的弹出菜单的创建

好久没弄了，只是实验一下，呵呵！
所涉及的API，就是一个TrackPopupMenu或者TrackPopupMenuEx！
原型如下：
BOOL TrackPopupMenu(
    HMENU hMenu,  //指向弹出菜单的句柄
    UINT uFlags,  //设置的标志位，用于指示弹出菜单的样式，如文字对齐方式
    int x,
    int y,    //弹出菜单的左上角位置
    int nReserved,
    HWND hWnd,    //接收弹出菜单消息的窗口
    HWND prcRect  //忽略
);
及
BOOL TrackPopupMenuEx(          HMENU hmenu,
    UINT fuFlags,
    int x,
    int y,
    HWND hwnd,
    LPTPMPARAMS lptpm
);
首先在资源里添加好一个菜单资源，如下：

IDR_POPMENU MENU 
BEGIN
    POPUP "1"
    BEGIN
        MENUITEM "弹出消息一",                       ID_SUB_ONE
        MENUITEM "弹出消息二",                       ID_SUB_TWO
        MENUITEM SEPARATOR
        MENUITEM "退出",                          ID_SUB_EXIT
    END
END

由于是在响应右键点击时弹出菜单的，所以在消息响应里处理WM_RBUTTOMDOWN消息时弹出菜单：
1、首先是获取一个菜单句柄

HMENU hMenu=LoadMenu(g_hInst,MAKEINTRESOURCE(IDR_POPMENU));
HMENU hSubMenu=GetSubMenu(hMenu,0);

2、其次是获取弹出菜单的左上角位置，这里是通过获取光标的位置来设置的：

POINT pos;
GetCursorPos(&pos);

3、接下来就是弹出菜单了，直接调用API：
TrackPopupMenu(hSubMenu,TPM_LEFTBUTTON,pos.x,pos.y,0,hDlg,NULL);

4、然后在WM_COMMAND消息里响应菜单消息，而这里wParam的高位16为0，低位16位对应的则是消息ID：

case WM_COMMAND:
      if(HIWORD(wParam)==0){
        switch(LOWORD(wParam)){
          case ID_SUB_ONE:
            MessageBox(hDlg,TEXT("对应菜单按钮一"),TEXT("Test"),0);
            return TRUE;
          case ID_SUB_TWO:
            MessageBox(hDlg,TEXT("对应菜单按钮二"),TEXT("Test"),0);
            return TRUE;
          case ID_SUB_EXIT:
            EndDialog(hDlg,0);
            return TRUE;
        }
      }

测试运行如下：

完整和代码如下：

#include
#include"resource.h"

HINSTANCE g_hInst;

INT_PTR CALLBACK MainDlgProc(HWND,UINT,WPARAM,LPARAM);

int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE,LPSTR lpCmdLine,int nShowCmd)
{
  g_hInst=hInstance;
  DialogBox(hInstance,MAKEINTRESOURCE(IDD_DIALOG1),NULL,MainDlgProc);
  return 0;
}

INT_PTR CALLBACK MainDlgProc(HWND hDlg,UINT uMsg,WPARAM wParam,LPARAM lParam)
{
  switch(uMsg){
    case WM_INITDIALOG:
      {
      HICON hIcon=LoadIcon(g_hInst,MAKEINTRESOURCE(IDI_MAIN));
      SendMessage(hDlg,WM_SETICON,ICON_BIG,(LPARAM)hIcon);
      SendMessage(hDlg,WM_SETICON,ICON_SMALL,(LPARAM)hIcon);
      SetWindowText(hDlg,TEXT("Test Popup Memu"));
      SetDlgItemText(hDlg,IDC_INFO,TEXT("Write By Iawen --2009.02.04"));  

      
      return TRUE;
      }
    case WM_SYSCOMMAND:
      switch(wParam)
      {
        case SC_CLOSE:
          DestroyWindow(hDlg);
          PostQuitMessage(0);
          return TRUE;
        case SC_MINIMIZE:
          return TRUE;
      }
    case WM_RBUTTONDOWN:
      {
      HMENU hMenu=LoadMenu(g_hInst,MAKEINTRESOURCE(IDR_POPMENU));
      HMENU hSubMenu=GetSubMenu(hMenu,0);

      POINT pos;
      GetCursorPos(&pos);      
      TrackPopupMenu(hSubMenu,TPM_LEFTBUTTON,pos.x,pos.y,0,hDlg,NULL);
      }
      return TRUE;
    case WM_COMMAND:
      if(HIWORD(wParam)==0){
        switch(LOWORD(wParam)){
          case ID_SUB_ONE:
            MessageBox(hDlg,TEXT("对应菜单按钮一"),TEXT("Test"),0);
            return TRUE;
          case ID_SUB_TWO:
            MessageBox(hDlg,TEXT("对应菜单按钮二"),TEXT("Test"),0);
            return TRUE;
          case ID_SUB_EXIT:
            EndDialog(hDlg,0);
            return TRUE;
        }
      }
  }
  return FALSE;
}
