C# 调用系统API.
从自己的软件,来操作别人写好的软件.
SendMessage
句柄 标识当前进程/控件的一个标识;
本课程所用到的常量信息:
private const uint LB_FINDSTRING = 0x18F;//查询项目在listbox中
private const uint LB_ADDSTRING = 0x180;//增加字符串在listbox中
private const uint LB_SETCURSEL = 0x186; //用于多选ListBox
private const uint LB_SETTOPINDEX = 0x197;//改变序号在ListBox
private const uint CB_FINDSTRING = 0x014C;//搜索字符串在下拉菜单中
private const uint CB_SETCURSEL = 0x014E;//设置下拉菜单的选中项
private const uint CB_SHOWDROPDOWN = 0x014F;//展开下拉菜单
private const uint BM_CLICK = 0x00F5;//按钮点击
引用其他非托管语言编写的DLL时.必须要加上此标志
关键字 方法所在的DLL 方法名称
[DllImport("user32.dll", EntryPoint = "FindWindow")]
权限修饰符 静态标志 修饰符 返回值类型 方法名(与调用方法相同)
private static extern IntPtr FindWindow(string IpClassName, string IpWindowName);
如何编写一个win32api的程序.
一、获取句柄
a) 从窗体标题中获取句柄/从进程中(pid)获取句柄
b) IntPtr.Zero 判断句柄是否为0
二、找到实现函数
a) SendMessage
三、函数的原型（搜索引擎，MSDN，玄机宝盒）
a) 可以使用宝盒的api速查
四、如何调用
a) EasyWin32Apis
找出窗体上所需要操控控件句柄,在进行消息传递.
