我想学别人做一个查看其他进程打开了那些文件handle的软件,好用来查看流氓软件....
我上传附件里面就是一个这样的软件(无毒,大家放心下载).
我的代码如下,可以得到所有进程的所有句柄,但是就是用GetFileSize就是得不到文件的Size....
都不知道为什么.......
有人可以指点一下我么?
代码如下:
#include <iostream>
#include <windows.h>
#include <AccCtrl.h>
#include <AclAPI.h>
#pragma comment(lib,"ntdll")
#define MAX_HANDLE_LIST_BUF 0x200000
#define OBJ_FILE 0x1c//猜测是这个..
#define OBJ_SOCKET 0x1a//据说这个时socket,但是又好像不是..
typedef long NTSTATUS;
extern "C" __declspec(dllimport) NTSTATUS __stdcall

IN ULONG SystemInformationLength, OUT PULONG ReturnLength OPTIONAL );
typedef struct _HandleInfo
{
USHORT dwPid;
USHORT CreatorBackTraceIndex;
BYTE ObjectType;
BYTE HandleAttributes;
USHORT HndlOffset;
DWORD dwKeObject;
ULONG GrantedAccess;
}HANDLEINFO, *PHANDLEINFO;
void AdjustDacl( HANDLE hProcess )
{

LPTSTR ptstrName = (LPTSTR)&world;

SET_ACCESS,
NO_INHERITANCE,

TRUSTEE_IS_SID,
TRUSTEE_IS_USER,ptstrName
}
};
ACL * pdacl = 0;
if ( SetEntriesInAcl(1, &ea, 0, &pdacl) != ERROR_SUCCESS )
printf( "SetEntriesInAcl Error:%d", GetLastError() );
if ( SetSecurityInfo(hProcess, SE_KERNEL_OBJECT,DACL_SECURITY_INFORMATION,0 , 0, pdacl, 0 ) != ERROR_SUCCESS )
printf( "SetSecurityInfo Error:%d", GetLastError() );
LocalFree(pdacl);
}//end of AdjustDacl

{
using namespace std;

AdjustDacl(hProc);
CloseHandle(hProc);
hProc=OpenProcess(WRITE_DAC,true,pHandleInfo->dwPid);
AdjustDacl(hProc);
CloseHandle(hProc);
hProc=OpenProcess(PROCESS_DUP_HANDLE,true,pHandleInfo->dwPid);
HANDLE hClone=NULL;
DuplicateHandle(hProc,(HANDLE)pHandleInfo->HndlOffset,GetCurrentProcess(),&hClone,/*STANDARD_RIGHTS_ALL*/0,FALSE,0);
CloseHandle(hProc);
GetFileSize(hClone,&Size);
//getlasterr 老是6(句柄错误)或者1(函数错误)...要怎么做才对?
if (GetLastError()==0)
