CBN_SELCHANGE  选择项改变时产生的消息

CBN_EDITCHANGE  输入改改时产生的消息:

LRESULT CALLBACK WindowProc(

HWND hwnd,       // handle to window

UINT uMsg,       // WM_COMMAND

WPARAM wParam,   // combo box identifier, CBN_EDITCHANGE

LPARAM lParam    // handle to combo box (HWND)

);

在WM_COMMAND事件中，选择项改变时，发生通知事件

case 1001://第1个下拉框ID

{

if(HIWORD(wparam)==CBN_SELCHANGE)

{

HWND com1=GetDlgItem(hwnd,1001);

HWND com2=GetDlgItem(hwnd,1002);

HWND com3=GetDlgItem(hwnd,1003);

int index=SendMessage(com1,CB_GETCURSEL,0,0);

if(index!=CB_ERR)

{

SendMessage(com2,CB_SETCURSEL,index,0);

SendMessage(com3,CB_SETCURSEL,index,0);

}

}

}

break;

列表框：LISTBOX

单列列表框-样式默认

多列列表框-样式加 LBS_MULTICOLUMN

操作选择与COMBOBOX一样，CB_改为LB_,如：添加项由CB_ADDSTRING改为 LB_ADDSTRING,当选择项改变后WM_COMMAND通知事件:LBN_SELCHANGE。

C++windows内核编程笔记day07_day08,可视化建菜单、加速键使用、绘图等

可视化操作创建的菜单,加载到窗口. 方法1:注册时指定菜单 wce.lpszMenuName=MAKEINTRESOURCE(IDR_MENUMAIN);//数字形式的资源ID转换为字符串形式的资源 方法2: //创建窗口时加载菜单资源 HMENU menumain= LoadMenu(g_hinstance,MAKEINTRESOURCE(IDR_MENUMAIN)); menumain 传入 CreateWindowEx();//倒数第三个参数 窗口指定小图标: 1.注册时指定 wce.hI

C++windows内核编程笔记day11 win32静态库和动态库的使用

windows库程序: 静态库: 源代码被链接到调用的程序或动态库,被调用时,代码最少有1份,文件后缀.LIB 动态库: 函数被程序或其他动态库调用,被调用时,代码只有1份,文件后缀.DLL 静态库(C语言): 创建时,选择文本类型文件,输入Clib.c,设置输出路径 ../lib/Clib.lib int Clib_add(int a,int b) { return a+b; } 同一上工作区,建立控制台程序(.c文件)调用静态库: #include<STDIO.H> #pragma com

C++windows内核编程笔记day13 进程、线程与信号量

Windows进程 进程是一个容器,包含程序执行需要的代码.数据.资源等信息, windows进程的特点: 每个进程都有自己的ID号 每个进程都有自己的地址空间,进程之间无法访问对方的地址空间. 每个进程都有自己的安全属性 每个进程至少包含一个线程. 获取和释放环境信息 GetEnvironmentStrings FreeEnvironmentStrings 获取或设置 本程序的环境变量 GetEnvironmentVariable SetEnvironmentVariable 示例: char

C++windows内核编程笔记day14 其他线程同步技术

线程同步技术: 原子锁 临界区(段) 互斥 事件 信号量(线程示例时已经使用过) 可等候定时器 使用范围:原子锁<临界区<互斥 效率:    原子锁>临界区(用户态)>互斥(内核态) 一般用临界区. //等候多个信号 DWORD WaitForMultipleObjects( DWORD nCount,             // number of handles in array CONST HANDLE *lpHandles,  // object-handle array

【转】VS2010/MFC编程入门之八（对话框：创建对话框类和添加控件变量）

原文网址:http://www.jizhuomi.com/software/153.html 前两讲中鸡啄米为大家讲解了如何创建对话框资源.创建好对话框资源后要做的就是生成对话框类了.鸡啄米再声明下,生成对话框类主要包括新建对话框类.添加控件变量和控件的消息处理函数等. 因为鸡啄米给大家的例程Addition是基于对话框的程序,所以程序自动创建了对话框模板IDD_ADDITION_DIALOG,并自动生成了对话框类CAdditionDlg,它是从CDialogEx类派生的.大家用过VC++6.0

原文:Windows 8.1 应用再出发 - 几种新增控件(2) 本篇我们接着来介绍Windows 8.1 的新增控件,分别是:Flyout.MenuFlyout.SettingsFlyout.Hub 和 Hyperlink. 1. Flyout Flyout被称为浮出控件,能起到提示或者简单交互作用.我们可以利用它来要求用户确认操作.收集用户输入信息或显示提示信息等.只有当用户点击时才显示Flyout,当点击外部任意点时,Flyout消失. Flyout通常会附加到Button上,所以Butt
