VB 从零开始编外挂(六)

--------------------------------------------------------------------------------------------------------------------------------------------------------
应用实战
--------------------------------------------------------------------------------------------------------------------------------------------------------
需要VB API函数：
FindWindow
GetWindowThreadProcessId
OpenProcess
ReadProcessMemory
CloseHandle
--------------------------------------------------------------------------------------------------------------------------------------------------------
相关API声明：
FindWindow
↓
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" ( ByVal lpClassName As String , ByVal lpWindowName As String ) As Long

GetWindowThreadProcessId
↓
Private Declare Function GetWindowThreadProcessId Lib "user32" ( ByVal hwnd As Long , lpdwProcessId As Long )
As Long

OpenProcess
↓
Private Declare Function OpenProcess Lib "kernel32" ( ByVal dwDesiredAccess As Long , ByVal bInheritHandle As Long , ByVal dwProcessId As Long ) As Long

ReadProcessMemory
↓
Private Declare Function ReadProcessMemory Lib "kernel32" ( ByVal hProcess As Long , ByVal lpBaseAddress As Any , ByVal lpBuffer As Any , ByVal nSize As Long , lpNumberOfBytesWritten As Long ) As Long

CloseHandle
↓
Private Declare Function CloseHandle Lib "kernel32" ( ByVal hObject As Long ) As Long

GetCurrentProcess
↓
Private Declare Function GetCurrentProcess Lib "kernel32" () As Long
--------------------------------------------------------------------------------------------------------------------------------------------------------
需要的控件： Label 、 Timer（interval不为空）、Text
--------------------------------------------------------------------------------------------------------------------------------------------------------
定义函数：
Dim SetHp As Integer ' 定义设定的体力值
Dim SetMp As Integer ' 定义设定的魔法值
Dim NowHp As Long ' 定义目前的体力值
Dim NowMp As Long ' 定义目前的魔法值
Dim MaxHp As Long ' 定义角色的最高体力值
Dim MaxMp As Long ' 定义角色的最高魔法值
Dim DiZhi As Long '定义内存地址函数
Dim hwnd As Long ' 储存 FindWindow 函数返回的句柄
--------------------------------------------------------------------------------------------------------------------------------------------------------
