请问点选右键菜单应该怎么处理?

我试过在WM_MENUSELECT下面去处理，结果只要鼠标移到菜单项上就执行菜单项的命令了，都不等我点击。怎样才能让它在点击时才执行呢?

晕，BN_CLICKED 本身也是 0
那我就不知道原因了
那会不会是 TrackPopupMenu 的倒数第二个参数弄错了？

我写代码试了试，是成功的

HMENU pop;

LRESULT CALLBACK WindowProcedure( HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam )
{
    switch (message)        /* handle the messages */
    {
        case WM_CREATE:
            pop = CreatePopupMenu();
            AppendMenu( pop, MF_STRING, 12345, TEXT("新增") );
            break;
        case WM_COMMAND:
            if( HIWORD(wParam)==BN_CLICKED && LOWORD(wParam)==12345 )
                MessageBox( hWnd, TEXT("good"), TEXT(""), MB_OK );
            break;
        case WM_CONTEXTMENU:
            TrackPopupMenu ( pop, 0, 0, 0, 0, hWnd, NULL );
            break;
        case WM_DESTROY:
            PostQuitMessage( 0 );
            break;
        default:
            return DefWindowProc( hWnd, message, wParam, lParam );
    }

    return 0;
}
