出现Windows Explorer has encountered a problem and needs to close.的错误

[naixian1983]

我用detours 来hook createfile（），但出现Windows Explorer has encountered a problem and needs to close. We are sorry for the inconvenience.的错误

DETOUR_TRAMPOLINE(HANDLE WINAPI MyCreateFileW(LPCWSTR lpFileName,DWORD dwDesiredAccess,DWORD dwShareMode,LPSECURITY_ATTRIBUTES lpSecurityAttributes,DWORD dwCreationDisposition,DWORD dwFlagsAndAttributes,HANDLE hTemplateFile), CreateFileW);
HANDLE WINAPI NewCreateFileW(LPCWSTR lpFileName,DWORD dwDesiredAccess,DWORD dwShareMode,LPSECURITY_ATTRIBUTES lpSecurityAttributes,DWORD dwCreationDisposition,DWORD dwFlagsAndAttributes,HANDLE hTemplateFile)

{

TCHAR   szBuffer[1024];   
 

UINT fixed;  

CString Drive_Letter;

CString Drive="G:";

fixed=GetDriveType(Drive);  

if (fixed==DRIVE_REMOVABLE)
{



Drive_Letter=Drive.Mid(0,1);

   
wsprintf(szBuffer,TEXT("%s"),Drive_Letter);

if(wcsncmp(lpFileName, (LPCWSTR)szBuffer,1) ==0 )
    {        
    SetLastError(ERROR_ACCESS_DENIED); 

    

        return INVALID_HANDLE_VALUE;


    }

    
}





return MyCreateFileW(lpFileName,dwDesiredAccess,dwShareMode,lpSecurityAttributes,dwCreationDisposition,dwFlagsAndAttributes,hTemplateFile);

}

请帮帮忙啊，那里错呢？谢了

可能哪里都没错，建议你先针对某一个固定的文件来处理，验证程序Hook及相关处理是否正确。
Hook CreateFile可以实现不让其它程序打开文件，但不能实现让其它程序认为没有文件，如果要禁止访问一个盘，需要Hook与此相关的各个API，或许Hook NtCreateFile能达到你的目的。
