C++ 重命名文件@C:\\Windows\\System32\\Drivers

Question

SOLVED: have a look on the later posts

TASK: rename a file called TabletFilter.sys ( its my graphic tablet driver ) because windows 8 (my OS) apps needs an other driver then photoshop for the pin pressure. And I want to write a c++ program that just rename all driver files to .old

The code based on the rename example from cplusplus.com

#include <stdio.h>

int main ()
{
  int result;
  char oldname[] ="TabletFilter.sys";
  char newname[] ="TabletFilter.sys.old";
  result= rename( oldname , newname );
  if ( result == 0 )
    puts ( "File successfully renamed" );
  else{
    result= rename( newname , oldname );
    if( result == 0)
      puts ( "File successfully renamed" );
    else
      perror( "Error renaming file" );
  }
  return 0;
}

I tried "run as Admin" as well, but I still get

Error renaming file: No such file or directory

what can I do?

---

EDIT:

The file is definitly in the same folder ... i copyed them both there... even at c:\\windows\\ i tryed it ... and i use a manifest

Executable: TabletRenameDriver.exe 
Manifest: TabletRenameDriver.exe.manifest
Sample application manifest file:
<?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="TabletRenameDriver"
     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="requireAdministrator"
          uiAccess="false"/>
        </requestedPrivileges>
       </security>
  </trustInfo>
</assembly>

i tryed uiAccess true and false.

Yes I have a problem with the rights The driver is loaded but iam still able to change his name ... dont know why, but its possbile. I tryed it. I want to solve this problem with c++ so pls dont tell me that there are many script languages out there that can handle the problem very well ;-) I know this

Answer 1

The error message

No such file or directory

Means that the current directory does not contain files names "TabletFilter.sys" or "TabletFilter.sys.old" .

What you can do is either:

1. Specify the full path to the file.
2. Ensure that the current directory, when your code executes, is the directory that contains your file.

However, even when you do this, your program may very well fail. You may not have sufficient rights to modify the contents of that folder. And the file you are trying to rename may well be locked if the OS has loaded the driver.

And as @Hans points out, the file system redirector could very well be confounding matters for you. The best way to avoid that is to us a 64 bit process.

I see no reason for using a C++ program here. Renaming files is a task best suited to a scripting language.

Thanks for all your help

I finished my programm and it works perfectly now

note: added "requireAdministrator" uiAccess="false" via VS2012 Settings

#include <stdlib.h>

    for(unsigned long tick = GetTickCount() / 1000;  tick + 2 > GetTickCount() / 1000;){
    }
}

With only 48 lines of code ... can a script be shorter?

PS: Revisiting this post after some time, I think there are quite a few ways to approach this issue differently. However, the main point still stands: If you want to do something like this, you have to run with admin permissions ... and maybe use loops, lists/vectors and some proper string manipulation :-P

Answer 3

Many of those drivers are needed by Windows to startup. If you did succeed in renaming them, bad things will happen to your machine when you restart - namely your machine would not boot.

As a general rule, leave all of the stuff in C:\\Windows alone, but this advice is ten-fold more important for the C:\\Windows\\drivers directory. Touch this folder and anything in it at your peril.
