Wie zu deaktivieren Virtuals für C ++ Programme?

Question

Ich würde mein Programm wie einen Fehler zu werfen, wenn es versucht, Dateien in einem geschützten Bereich, wie die Wurzel des C zu erstellen: \ Laufwerk (zB: FILE* FileHandle = fopen("\\file.txt", a)). Stattdessen wird die Datei im Virtual Store unter% APPDATA% erstellt wird.

Wie kann ich das Virtual Store deaktivieren?

Danke

EDIT: Nur klar zu sein, ich frage nicht, wie die Sicherheit zu umgehen und meine Datei in einem geschützten Ort erstellen. Ich mag die Erstellung der Datei zu FAIL, so dass ich den Benutzer kann sagen, er war ein Idiot.

Answer 1

You add an application manifest. Choose asInvoker, highestAvailable, or requireAdministrator. It sounds like you want asInvoker.

From http://msdn.microsoft.com/en-us/library/bb756929.aspx:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> 
  <assemblyIdentity version="1.0.0.0"
     processorArchitecture="X86"
     name="IsUserAdmin"
     type="win32"/> 
  <description>Description of your application</description> 
  <!-- Identify the application security requirements. -->
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
    <security>
      <requestedPrivileges>
        <requestedExecutionLevel
          level="asInvoker"
          uiAccess="false"/>
        </requestedPrivileges>
       </security>
  </trustInfo>
</assembly>

Answer 2

From MSDN:

Virtualization is only enabled for:

• 32 bit interactive processes
• Administrator writeable file/folder and registry keys

Virtualization is disabled for:

• 64 bit processes
• Non-interactive processes
• Processes that impersonate
• Kernel mode callers
• Executables that have a requestedExecutionLevel

Your best bet, as Adam Maras noted, is to set a requestedExecutionLevel on your application by adding a manifest. A requestedExecutionLevel of "asInvoker" will cause file operations to fail on protected locations, rather than redirecting to the virtual store or prompting for elevation.

Here is an article that shows how to turn off the virtualization.

http://www.interworks.com/blogs/dsmith/2011/09/21/disabling-windows-7-virtual-store

The short of it is:

-From the Windows 7 Start Orb, do a search for Local Security Policy and select it.

-Expand Local Policies and click on Security Options. On the right pane, scroll all the way to the bottom and you will find a setting called " User Account Control: Virtualize file and registry write failures to per-user locations", double click on that setting and change it to Disabled.
