Windows应用程序的管理员权限

Question

I need to create and write to a file under C:\\ on Windows. This obviusly require Administrator right.

My application consist on:

• the CORE (.exe)
• two .dll

Now, I saw a lot of time software (like games) that require Admin right during installation and after they can do whatever they want; how is this possible?

How could I do that via C++ ?

Answer 1

If you want your application to always run as administrator, you can specify this in your application's manifest file.

Specifically, you will need to add something like this:

<trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
  <security>
    <requestedPrivileges>
      <requestedExecutionLevel level="requireAdministrator" uiAccess="false"/>
    </requestedPrivileges>
  </security>
</trustInfo>

More on application manifest files can be found in MSDN.
