对于一直觉得科技就是要提高生产力的我这个硬件工程师来说，要编写这些更复杂的程序，真是件吃力不讨好的事，好在，我不需要赶时间，有空兴趣就搞一下，没空没心情完全可以不用理，最近，因为工作上又有了相关需要（非必要的需要、完全出于个人爱好），才又拾起心情，继续之前一直未完成的事情，这次，总算有了进展，一直未解决的问题，得到了解决。
本次实现如下功能：
1、捕获其他程序窗口句柄
2、单击其他程序的菜单
3、读取其他软件listview控件的内容
4、设置其他程序的下拉框的选择
5、设置其他程序Edit框的值
6、单击其他程序按钮
1、添加相关引用：
Imports System.Collections.Generic
Imports System.ComponentModel
Imports System.Data
Imports System.IO
Imports System.Drawing
Imports System.Linq
Imports System.Text
‘Imports System.Threading.Tasks
Imports System.Threading.Thread
Imports System.Windows.Forms
Imports System.Runtime.InteropServices
2、首先定义相关常量（相关常量的定义，可以从c语言的头文件windows.h 、winbase.h 、commdlg.h 、commctrl.h 、winuser.h 等中找到）：
Private Const LVIS_SELECTED As UInteger = &H2
Private Const LVM_FIRST As UInteger = &H1000
Private Const HDM_FIRST As UInteger = &H1200 ‘// Header messages
Private Const HDM_GETITEMA As UInteger = (HDM_FIRST + 3)
Private Const HDM_GETITEMW As UInteger = (HDM_FIRST + 11)
Private Const HDM_GETITEM As UInteger = HDM_GETITEMW
‘获取列表头内的内容
Private Const LVM_GETHEADER As UInteger = LVM_FIRST + 31
Private Const LVM_GETITEMCOUNT As UInteger = LVM_FIRST + 4
‘获取列表行数
Private Const LVM_GETITEMTEXT As UInteger = LVM_FIRST + 45
‘获取列表内的内容
Private Const LVM_GETITEMW As UInteger = LVM_FIRST + 75
Private Const LVM_SETITEMSTATE As UInteger = LVM_FIRST + 43
Private Const HDM_GETITEMCOUNT As UInteger = &H1200
‘获取列表列数
Private Const PROCESS_VM_OPERATION As UInteger = &H8
‘允许函数VirtualProtectEx使用此句柄修改进程的虚拟内存
Private Const PROCESS_VM_READ As UInteger = &H10
‘允许函数访问权限
Private Const PROCESS_VM_WRITE As UInteger = &H20
‘允许函数写入权限
Private Const MEM_COMMIT As UInteger = &H1000
‘为特定的页面区域分配内存中或磁盘的页面文件中的物理存储
Private Const MEM_RELEASE As UInteger = &H8000
Private Const MEM_RESERVE As UInteger = &H2000
‘保留进程的虚拟地址空间,而不分配任何物理存储
Private Const PAGE_READWRITE As UInteger = 4

Private LVIF_TEXT As Integer = &H1
Private LVIF_IMAGE As Integer = &H2
Private LVIF_PARAM As Integer = &H4
Private LVIF_STATE As Integer = &H8
Private Const HDI_TEXT = &H2
Private Const LVM_SETITEMTEXTA As UInteger = LVM_FIRST + 46
Private Const LVM_SETITEMTEXTW As UInteger = LVM_FIRST + 116
Private Const LVM_SETITEMTEXT As UInteger = LVM_SETITEMTEXTW
Friend WithEvents Button2 As System.Windows.Forms.Button
Friend WithEvents Button3 As System.Windows.Forms.Button
Private Const LVIS_STATEIMAGEMASK As UInteger = &HF000
‘#define LVM_SETITEMTEXTA (LVM_FIRST + 46)

Private Const WM_SYSCOMMAND = &H112

Private components As System.ComponentModel.IContainer
Private Const WM_COMMAND = &H111
Private Const WM_SETTEXT = &HC
Private Const BM_CLICK = &HF5
Private Const CB_SETCURSEL = &H14E
Dim headerhwnd As Integer
‘listview控件的列头句柄
