关于WriteProcessMemory的写入，大侠们告诉我一下....

Question

void CSdfDlg::OnButton2()  
{
// TODO: Add your control notification handler code here
HWND hwnd;
hwnd=::FindWindow(NULL,WndName);
DWORD pid;
::GetWindowThreadProcessId(hwnd,&pid);
HANDLE Process;
Process=::OpenProcess(PROCESS_ALL_ACCESS,false,pid);
int sum;
TCHAR buf[10];
::ReadProcessMemory(Process,(LPCVOID)(0x006a9ec0),&sum,4,0);
::ReadProcessMemory(Process,(LPCVOID)(sum+0x82c),&sum,4,0);
::ReadProcessMemory(Process,(LPCVOID)(sum+0x28),&sum,4,0);
_itoa(sum,buf,10);
::SetWindowText(m_edit2_hwnd,buf);
}
上面的ReadProcessMemory能读出来，但是WriteProcessMemory错误????
还有为什么我这样写入不行，连接的程序直接退出了？
void CSdfDlg::OnButton3()  
{
// TODO: Add your control notification handler code here
HWND hwnd;
hwnd=::FindWindow(NULL,WndName);
DWORD pid;
::GetWindowThreadProcessId(hwnd,&pid);
HANDLE Process;
Process=::OpenProcess(PROCESS_ALL_ACCESS,false,pid);
int sum=3000;
::WriteProcessMemory(Process,(LPVOID)(0x006a9ec0),&sum,4,0);
::WriteProcessMemory(Process,(LPVOID)(sum+0x82c),&sum,4,0);
::WriteProcessMemory(Process,(LPVOID)(sum+0x28),&sum,4,0);
}
 
 
 

Answer 1

::WriteProcessMemory(Process,(LPVOID)(sum+0x82c),&sum,4,0);你上面的地址正确？确定可写？

Answer 2

首先确保Process=::OpenProcess(PROCESS_ALL_ACCESS,false,pid);中的process有效，进行一行判断是否为0，GetLastError（）查错。
关键是你写入的地址，这个很重要，有些地址是不能写的，会出错，完了你在拿GetLastError查查错误。

Answer 3

Process有效的，地址也是没有错的，这个地址是植物大战阳光的地址，我用
Process=::OpenProcess(PROCESS_ALL_ACCESS,false,pid);
int sum;
TCHAR buf[10];
::ReadProcessMemory(Process,(LPCVOID)(0x006a9ec0),&sum,4,0);
::ReadProcessMemory(Process,(LPCVOID)(sum+0x82c),&sum,4,0);
::ReadProcessMemory(Process,(LPCVOID)(sum+0x28),&sum,4,0);
_itoa(sum,buf,10);
::SetWindowText(m_edit2_hwnd,buf);
是能读出来的，但是写入就是不行，网上查的那些都是答非所问

Answer 4

::ReadProcessMemory(Process,(LPCVOID)(sum+0x82c),&sum,4,0);
你这句就有问题啊，我晕，sum+0x82c啥意思，sum你只声明了就没定义，sum是一个随机数再加上0x82c你说等于啥，对不，你再看看。
::ReadProcessMemory(Process,(LPCVOID)(sum+0x28),&sum,4,0);
而且sum是int类型

Answer 5

Process=::OpenProcess(PROCESS_ALL_ACCESS,false,pid);
int sum;
TCHAR buf[10];
::ReadProcessMemory(Process,(LPCVOID)(0x006a9ec0),&sum,4,0);
::ReadProcessMemory(Process,(LPCVOID)(sum+0x82c),&sum,4,0);
::ReadProcessMemory(Process,(LPCVOID)(sum+0x28),&sum,4,0);
_itoa(sum,buf,10);
::SetWindowText(m_edit2_hwnd,buf);
这个是对的，能读出阳光的数值.........

Answer 6

看明白了::ReadProcessMemory(Process,(LPCVOID)(sum+0x82c),&sum,4,0);
这句是把sum的值加上0x82c
你在写的时候是不是地址顺序不对，应该是这样
::WriteProcessMemory(Process,(LPVOID)(sum+0x28),&sum,4,0);
::WriteProcessMemory(Process,(LPVOID)(sum+0x82c),&sum,4,0);
::WriteProcessMemory(Process,(LPVOID)(0x006a9ec0),&sum,4,0);
你读和写的顺序应该是相反的
