列出进程 对进程操作

列出和操作进程是非常重要的

列出进程我们使用palist函数:

void pslist(void)
{
	HANDLE hProcessSnap = NULL;
	PROCESSENTRY32 pe32= {0};
	hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
	if (hProcessSnap == (HANDLE)-1)
	{
		printf("\nCreateToolhelp32Snapshot() failed:%d",GetLastError());
		return ;
	}
	pe32.dwSize = sizeof(PROCESSENTRY32);
	printf("\nProcessName　　　　 ProcessID");
	if (Process32First(hProcessSnap, &pe32))
	{
		char a[5];
		do
		{
			itoa(pe32.th32ProcessID,a,10);
			printf("\n%-20s%d",pe32.szExeFile,pe32.th32ProcessID);
		}
		while (Process32Next(hProcessSnap, &pe32));
	}
	else
	{
 		printf("\nProcess32Firstt() failed:%d",GetLastError());
	}
	CloseHandle (hProcessSnap);
	return;
}

上边的代码列出了进程的PID,有了PID我们就可以使用PSKILL关掉进程:

BOOL killps(DWORD id)
{
	HANDLE hProcess=NULL,hProcessToken=NULL;
	BOOL IsKilled=FALSE,bRet=FALSE;
	try
	{

		if(!OpenProcessToken(GetCurrentProcess(),TOKEN_ALL_ACCESS,&hProcessToken))
		{
			printf("\nOpen Current Process Token failed:%d",GetLastError());
			leave;
		}
		//printf("\nOpen Current Process Token ok!");
		if(!SetPrivilege(hProcessToken,SE_DEBUG_NAME,TRUE))
		{
			leave;
		}
		printf("\nSetPrivilege ok!");

		if((hProcess=OpenProcess(PROCESS_ALL_ACCESS,FALSE,id))==NULL)
		{
			printf("\nOpen Process %d failed:%d",id,GetLastError());
			leave;
		}
		//printf("\nOpen Process %d ok!",id);
		if(!TerminateProcess(hProcess,1))
		{
			printf("\nTerminateProcess failed:%d",GetLastError());
			leave;
		}
		IsKilled=TRUE;
	}
	finally
	{
		if(hProcessToken!=NULL) CloseHandle(hProcessToken);
		if(hProcess!=NULL) CloseHandle(hProcess);
	}
	return(IsKilled);
}

BOOL SetPrivilege(HANDLE hToken,LPCTSTR lpszPrivilege,BOOL bEnablePrivilege)     //提升权限
{
	TOKEN_PRIVILEGES tp;
	LUID luid;

	if(!LookupPrivilegeValue(NULL,lpszPrivilege,&luid))
	{
		printf("\nLookupPrivilegeValue error:%d", GetLastError() ); 
		return FALSE; 
	}
	tp.PrivilegeCount = 1;
	tp.Privileges[0].Luid = luid;
	if (bEnablePrivilege)
		tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
	else
		tp.Privileges[0].Attributes = 0;
	AdjustTokenPrivileges(
				hToken, 
				FALSE, 
				&tp, 
				sizeof(TOKEN_PRIVILEGES), 
				(PTOKEN_PRIVILEGES) NULL, 
				(PDWORD) NULL); 
	if (GetLastError() != ERROR_SUCCESS) 
	{ 
		printf("AdjustTokenPrivileges failed: %u\n", GetLastError() ); 
		return FALSE; 
	} 
	return TRUE;
}
