MFC編程小技巧——強制殺死進程

    在某些應用場合下，咱們可能須要在啓動A進程啓動時關閉進程B。MFC下該如何作呢？如下是我項目中用到的代碼：

 

int KillProcess(DWORD Pid)
{
	//打開進程獲得進程句柄
	HANDLE hProcess=OpenProcess(PROCESS_ALL_ACCESS,FALSE,Pid);
	if(hProcess==NULL)
	{ 		
		printf("OpenProcess error\n");
		return 0;
	}
	//結束進程
	if (TerminateProcess(hProcess,0))
	{
		printf("結束進程成功\n");
		return 0;
	}
	else
	{
		printf("結束進程失敗\n");
		return 0;
	}	
}

int GetProcess()
{
	char buff[1024]={0};
	PROCESSENTRY32 pe32;
	pe32.dwSize=sizeof(pe32);
	//得到系統內全部進程快照
	HANDLE hProcessSnap=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
	if(hProcessSnap==INVALID_HANDLE_VALUE)
	{
		printf("CreateToolhelp32Snapshot error");
		return 0;
	}
	//枚舉列表中的第一個進程
	BOOL bProcess=Process32First(hProcessSnap,&pe32);
	while(bProcess)
	{
		//格式化進程名和進程ID
		wsprintf(buff,"%s---------------%d\r\n",pe32.szExeFile,pe32.th32ProcessID);
		//輸出進程名和進程ID
		printf(buff);
		memset(buff,0x00,1024);	
		//繼續枚舉進程
		bProcess=Process32Next(hProcessSnap,&pe32);
	}
	CloseHandle(hProcessSnap);
	return 0;
}

bool EnableDebugPrivilege()    
{    
    HANDLE hToken;    
    LUID sedebugnameValue;    
    TOKEN_PRIVILEGES tkp;    
    if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken)) 
    {    
        return   FALSE;    
    }    
    if (!LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &sedebugnameValue))   
    {    
        CloseHandle(hToken);    
        return false;    
    }    
    tkp.PrivilegeCount = 1;    
    tkp.Privileges[0].Luid = sedebugnameValue;    
    tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;    
    if (!AdjustTokenPrivileges(hToken, FALSE, &tkp, sizeof(tkp), NULL, NULL))  
    {    
        CloseHandle(hToken);    
        return false;    
    }    
    return true;    
} 

void CAngleDetectSystemDlg::CloseSecondSys()
{
	EnableDebugPrivilege();
	int     rc = 0;  
	HANDLE  hSysSnapshot = NULL;  
	PROCESSENTRY32 proc;  
	hSysSnapshot = CreateToolhelp32Snapshot ( TH32CS_SNAPPROCESS, 0 );  
	if ( hSysSnapshot == (HANDLE)-1 )   return;  
	proc.dwSize = sizeof(proc);  
	if ( Process32First ( hSysSnapshot, &proc ) )  
	{    
		do  {        
			if (stricmp(proc.szExeFile, "從機檢測系統.exe") == 0) 
			{
				HANDLE Proc_handle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, proc.th32ProcessID);           
				if (Proc_handle==NULL || !TerminateProcess(Proc_handle, 0)) rc = 1;           
				else rc = 0;       
			}     
		}   while ( Process32Next ( hSysSnapshot, &proc ) );
	}

	CloseHandle ( hSysSnapshot );  
	
	return;
}

 

    其中void CAngleDetectSystemDlg::CloseSecondSys()是關閉進程的函數，「從機檢測系統.exe」是須要關閉的進程，你能夠換成本身須要關閉的進程名稱。注意在關閉其餘進程時，須要提高當前進程的權限。

    順便附上在A進程中啓動B進程的代碼：

 

void CAngleDetectSystemDlg::OpenSecondSys()
{
	SHELLEXECUTEINFO sys2_shell = {sizeof(sys2_shell)};
	sys2_shell.fMask = SEE_MASK_FLAG_DDEWAIT;
	sys2_shell.lpVerb = "open";
	sys2_shell.lpFile = "從機檢測系統.exe";
	sys2_shell.nShow = SW_NORMAL;
	ShellExecuteEx(&sys2_shell);
}
