一提到进程保护特别是在Windows下,没有最安全,只有更安全。下面的代码是在用户层,截获任务管理器的本进程名(Test.exe)被选中时的消息,以防止用任务管理器结束掉进程(当然你用其他进程工具当然可以结束掉咯!)。主要是要学习这里面的方法、熟悉几个结构体、几个API而矣:
1、LVITEM
Specifies or receives the attributes of a list-view item. This structure has been updated to support a new mask value (LVIF_INDENT) that enables item indenting. This structure supersedes the LV_ITEM structure.
(我这水平的英文也能凑合着看吧,相信你更没问题!)
view plaincopy to clipboardprint?
typedef struct _LVITEM {
UINT mask;
int iItem;
int iSubItem;
UINT state;
UINT stateMask;
LPTSTR pszText;
int cchTextMax;
int iImage;
LPARAM lParam;
#if (_WIN32_IE >= 0x0300)
int iIndent;
#endif
#if (_WIN32_IE >= 0x560)
int iGroupId;
UINT cColumns; // tile view columns
PUINT puColumns;
#endif
} LVITEM, *LPLVITEM;
typedef struct _LVITEM {
UINT mask;
int iItem;
int iSubItem;
UINT state;
UINT stateMask;
LPTSTR pszText;
int cchTextMax;
int iImage;
LPARAM lParam;
#if (_WIN32_IE >= 0x0300)
int iIndent;
#endif
#if (_WIN32_IE >= 0x560)
int iGroupId;
UINT cColumns; // tile view columns
PUINT puColumns;
#endif
} LVITEM, *LPLVITEM;
2、FindWindow与FindWindowEx
view plaincopy to clipboardprint?
// 查找任务管理器ListView窗口句柄
HWND hwnd;
hwnd=FindWindow("#32770",_T("Windows 任务管理器"));
hwnd=FindWindowEx(hwnd,0,"#32770",0);
hwnd=FindWindowEx(hwnd,0,"SysListView32",0);
// Windows任务管理器尚未启动则返回
if (!hwnd)
return;
// 查找任务管理器ListView窗口句柄
HWND hwnd;
hwnd=FindWindow("#32770",_T("Windows 任务管理器"));
hwnd=FindWindowEx(hwnd,0,"#32770",0);
hwnd=FindWindowEx(hwnd,0,"SysListView32",0);
// Windows任务管理器尚未启动则返回
if (!hwnd)
return;
3、上面的结构体与API熟悉后,再看看这个函数吧!
