CopyFile2没有绕道而行

问题描述

嘿伙计们，



我被困住了。出于某种原因，我需要在Windows 8上阻止文件系统的复制功能。直到Windows 7，ShFileOperation& CopyFile用来做技巧。但是，在Windows 8中，由于我可以通过API监视器进行扫描，因此使用了一个新的API：CopyFile2来完成这项工作。所以我需要绕开CopyFile2。



我尝试使用Detour 2.x& 3.x沿着Windows SDK 6.x，7.x和Win8 SDK。以下是代码片段 -

Hey Guys,

I am stuck. For some reason, I need to block Copy feature of the file system on Windows 8. Till Windows 7, ShFileOperation & CopyFile used to do trick. However, with Windows 8, as I could scan through API monitor, a new API: CopyFile2, has been used to do the job. So I need to detour CopyFile2.

I tried doing this using Detour 2.x & 3.x along windows SDK 6.x, 7.x and Win8 SDK. Following is the code snippet -

HRESULT (WINAPI *Trampoline_CopyFile2)(PCWSTR pwszExistingFileName, PCWSTR pwszNewFileName, COPYFILE2_EXTENDED_PARAMETERS *pExtendedParameters) = CopyFile2;
HRESULT WINAPI Detour_CopyFile2(PCWSTR pwszExistingFileName, PCWSTR pwszNewFileName, COPYFILE2_EXTENDED_PARAMETERS *pExtendedParameters)
{
    OutputDebugString(L"Inside TrozenCopyFile...");
    return Trampoline_CopyFile2(pwszExistingFileName, pwszNewFileName, pExtendedParameters);
}

//Attaching Detour 
DetourAttach( &(PVOID&)Trampoline_CopyFile2, (PVOID)Detour_CopyFile2);

DetourAttach返回0（成功），但我没有接到对蹦床功能的调用。我知道我的dll正在加载资源管理器，因为其他API正在绕道而行 - 我也在ProcessExplorer中检查了它。



微软Detour Library是否支持win8 API？如果是的话，我做错了吗？如果不是，我是否应该将此作为错误报告？



帮助我们......对于任何甚至可以暗示我的人来说都是满分......

此外，我创建了一个示例应用程序调用CopyFile2。我的Dll正在加载并且DetourAttach返回0.但是，我仍然无法获得Detour_CopyFile2的痕迹



- Varun

DetourAttach returns 0(Successful), but I do not receive call to my Trampoline function. I know my dll is getting loaded in Explorer because other APIs are getting detoured - and I have checked it in ProcessExplorer too.

Does microsoft Detour Library support win8 APIs? If yes, am I doing anything wrong? If No, shall I report this as a bug?

Help me guys... Full points to anybody who can even hint me...

Further more, I create a sample application calls CopyFile2. My Dll is getting loaded and DetourAttach is returning 0. However, I am still unable to get traces to Detour_CopyFile2

推荐答案

HRESULT WINAPI CopyFile2(
  _In_      PCWSTR pwszExistingFileName,
  _In_      PCWSTR pwszNewFileName,
  _In_opt_  COPYFILE2_EXTENDED_PARAMETERS *pExtendedParameters
);

HRESULT (WINAPI *Trampoline_CopyFile2(PCWSTR pwszExistingFileName, PCWSTR pwszNewFileName, COPYFILE2_EXTENDED_PARAMETERS *pExtendedParameters)) = new CopyFile2();
HRESULT WINAPI Detour_CopyFile2(PCWSTR pwszExistingFileName, PCWSTR pwszNewFileName, COPYFILE2_EXTENDED_PARAMETERS *pExtendedParameters)
{
    OutputDebugString(L"Inside TrozenCopyFile...");
    return Trampoline_CopyFile2(pwszExistingFileName, pwszNewFileName, pExtendedParameters);
}
 
//Attaching Detour 
DetourAttach( &(PVOID&)Trampoline_CopyFile2, (PVOID)Detour_CopyFile2);
