Windows 7

Starting programs with administrator rights at login

Posted in Windows 7 on June 25th, 2010 by Mr. Bungle – Be the first to comment

With the introduction of UAC in Vista, launching a program that requires administrative rights on Windows startup (when you first log in) has become more difficult. One solution that has been doing the rounds is to use the Task Scheduler as a workaround. What a mess!

Provided you are not running a ‘home’ edition of Windows Vista/7, I have found what I believe is the cleanest and easiest way to achieve this:

1. Start->Run-> “gpedit.msc”
2. User Configuration->Windows Settings->Scripts (Logon/Logoff)
3. Double-click ‘Logon’, and add entries for each of the applications you want launched.

Group Policy Logon

The applications you define in here will be launched with administrator rights when you logon without any UAC dialogs being displayed.

FreeCommander + SuperCopier2

Posted in Data Management, Software, Windows 7 on March 9th, 2010 by Mr. Bungle – 20 Comments

As fun as file systems are, you really don’t want to be spending longer than you have to when it comes to copying / moving / viewing files and navigating folders. I was saved years of grief fumbling about with Windows Explorer thanks to a mate’s advice to switch to TotalCommander back in 2003 (I still remember his look of horror when when I said ‘Total-what?’). When it comes to speed and efficiently, the keyboard is king, and TotalCommander and all the other *commander variants take advantage of that.

Last year I switched to FreeCommander, and am very happy. The main benefits for me are:

  • a more modern / nicer UI
  • ‘type to navigate’
  • plenty of customisation options
  • it’s free :)

Unfortunately there are some serious drawbacks:

  • The file-copy/move dialog is the Windows built-in one (which is down-right horrible)
  • The file-delete dialog is the Windows built-in one, and it’s modal to the application
  • The FTP client has a terrible time-out issue and is generally buggy

I’d like to solve all three of these, but I’m starting with the first.

Luckily, FreeCommander allows you to use an external copy/move program via an INI setting. I tried the free TeraCopy for a while, but when I discovered SuperCopier 2, it was perfect! It really is lightning quick at what it does, it doesn’t get in your way, and has all the options you need (pause, error handling etc.). The only problem is, as of v2.2, the copy interception code was re-written, and it could no longer be fully integrated with FreeCommander. To solve this problem, I have written a small executable in C++ called SC2Integration.exe that uses the API provided by SuperCopier 2 (available on their sourceforge site) to re-unite FreeCommander with this excellent file-copy replacement.

Simply drop SC2Integration.exe into your FreeCommander installation folder (or anywhere else you would like to store it) and add the following two lines under the [Form] section of your FreeCommander.ini file:


FileCopyPrg=%FcSrcPath%\SC2Integration.exe Copy "%ActivSelAsFile%" "%InactivDir%"
FileMovePrg=%FcSrcPath%\SC2Integration.exe Move "%ActivSelAsFile%" "%InactivDir%"

If you didn’t copy SC2Integration.exe into your FreeCommander installation directory, replace %FcSrcPath% with the full correct path (no quotes). On Windows 7 your FreeCommander.ini file is here by default:

C:\Users\username\AppData\Roaming\FreeCommander\FreeCommander.ini

Download the SC2Integration utility for free here.

UPDATE: If you get an error ‘Parsing arguments…’, make sure you add double quotes around %ActivSelAsFile% and %InactivDir% in your FreeCommander.ini.

Windows 7 disconnected network drives

Posted in Networking, Software, Windows 7 on March 7th, 2010 by Mr. Bungle – 15 Comments

Mapped network drives have always been a buggy area in Windows, probably at least in part because they are still linked to a DOS namespace. From MSDN:

On Windows Server 2003 and Windows XP, the WNet functions create and delete network drive letters in the MS-DOS device namespace associated with a logon session…

Whatever the reason, it is commonly reported that mapped network drives appear as ‘disconnected’ in Windows Explorer (or ‘unavailable’ via net use), and that programs that attempt to use these drive mappings will fail until the user physically clicks on the drive letter in Windows Explorer. Only this user-initiated action will restore the connection and allow other programs to successfully read from the drive letter.

The dreaded disconnected network drive balloon.

This is a BIG problem!

I initially thought that the mapping of the network drives was being done before some required services had started (such as the Workstation and Server services), so I wrote a program to run on startup that attempted to map a drive and logged all the currently running services if it failed. It would keep trying to map a drive until it succeeded. I hoped it would show me which services needed to be running in order to map a drive, after which I would write a program to wait for those services before attempting to map anything. But, much to my amazement, I found that when the initial drive mapping failed and a subsequent attempt succeeded, the set of running services had not changed! So I could only conclude that there was another element in the equation. After thinking about this for a while, and reading this post, which indicates that Microsoft is apparently trying to address this, I decided ‘stuff it’, I’ll just write something that I know will work and is simple.

So I’ve written a small executable called MapDrive.exe to ‘work around’ this problem, described on the following dialog:

About MapDrive

Now as you may know since Vista, there is the concept of a split user token, and mapped network drives apply to only one token, so if you map drives as a standard user and then run an elevated process, those network drives are not available to the elevated process. This behaviour is documented by Microsoft, however the solution they offer is both unsupported and unsafe. Other solutions have been proposed here. If you don’t wish to use any of these solutions, you can do this:

1. Run MapDrive.exe as a shortcut from your Startup folder. This will map drives for the standard user token.
2. Run MapDrive.exe as a local group policy logon script using gpedit.msc. This will map drives for the administrator token.

Note: After using this program, you may still see the above balloon popup, simply click the spanner icon, and select ‘Hide icon and notifications’ for ‘Windows Explorer’.

Download the utility for free here.

UPDATE: A few people have asked how to use this program. As stated above, there are two ways, depending on whether you need drives mapped for standard users or admins. If you don’t know what you need, you probably just need to do this for standard users. Here are the steps for both:

1. Copy MapDrive.exe to somewhere on your local hard drive.

Standard Users:
2. Right-click MapDrive.exe and choose ‘Create Shortcut’. This will create a file called ‘MapDrive.exe – Shortcut’ next to MapDrive.exe. Now go Start->All Programs, right-click the ‘Startup’ folder and choose ‘Open’. Now copy the shortcut file you made before to this folder. Now right-click the shortcut file and choose ‘Properties’. Add the drive letter and network share as argument to the end of the ‘Target’ field e.g. “C:\Users\joeblogs\Documents\MapDrive.exe s: \\server\share 20″. You are done, next time you reboot, your s: should be mapped successfully for standard users.

Admin Users:
3. Press Win+R, type gpedit.msc, go User Configuration->Windows Settings->Scripts. Double-click Logon, click ‘Add’ and enter script name (no quotes): “C:\Users\joeblogs\Documents\MapDrive.exe” and script parameters (no quotes): “s: \\server\share 20″, ok, ok, done. You are done, next time you reboot, your s: should be mapped successfully for admin users (i.e. elevated programs).

Network CHMs = Pain courtesy of IE

Posted in Networking, Software, Windows 7 on February 19th, 2010 by Mr. Bungle – Be the first to comment

Despite being around since 1997, CHM files still remain a popular format for program help / documentation as well as ebooks. But opening them from a network drive was outlawed in 2005 after Microsoft released this security update. There was a registry hack workaround to enable it again, however this no longer works in Windows 7. The solution accepted on this thread involves two steps:

1. Add this registry key:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000001

2. In Internet Explorer->Tools->Internet Options and add your network drive into the safe/trusted zones.

Just the thought of firing up IE gives me the security-shivers and I really don’t want to be messing about with ‘trusted zones’ – I don’t trust IE to do anything. I’m surprised the US government hasn’t yet advised its citizens against using IE, like Australia, France and Germany have.

Of course the whole reason this has anything to do with IE is because the built in HH.exe that is the default Html Help viewer on Windows uses IE as the web browser engine to display and navigate the HTML files inside the CHM. So we could avoid this whole problem if there was a CHM viewer that doesn’t use IE at all. Now to the motivation for this post:

Enter xCHM – this is an open-source project that predominantly provides support for viewing CHM files on non-windows platforms, however it has been ported to Windows, so you can kiss HH.exe goodbye, and open your CHMs from any network location without having to hack your registry or mess with IE zones!!

Download the Windows port of xCHM (look under xCHM for Win32).

Win7 Library Tool

Posted in Software, Windows 7 on November 3rd, 2009 by Mr. Bungle – 213 Comments

Windows 7 libraries are a really useful feature of Windows 7, however unfortunately they arrive in a slighly cut-down form out of the box.  Microsoft decided against exposing some really useful capabilities to users, like adding network locations, pretty much the first thing I tried to do.  You get this message:

windows7libraryerror

Luckily, you can add network locations (and any other un-indexed locations), but it must be done programatically.  MS supply a command line utility slutil.exe, candidate for the worst named executable in history.  Pretty sure it stands for shell_library_util.  Anyway, I decided to write a tool to make it easy to add network locations, and added a few other features as well:

  • Add network (UNC or mapped drive) and any other un-indexed folders to libraries.
  • Backup library configuration, such that a saved set of libraries can be instantly restored at any point (like after a re-install of the OS or for transfer between multiple computers).
  • Create a mirror of all libraries (using symbolic links) in [SystemDrive]:\libraries.  This means you can reference all your files using a much shorter path, and also provides another entry-point to your files in many places in the Operating System (e.g. file open/save dialogs).
  • Change a library’s icon.

win7librarytool

Hopefully it’s easy enough to use, so I don’t have to explain it :)

You can download it for free below.  (Note: This will only run on >= Windows 7.)

I must give credit to Josh Smith for his TreeView CodeProject article, upon which this solution is modelled.

The application uses the Microsoft API CodePack to manipulate libraries, which I encourage you to check out if you are writing software to integrate / take advantage of new features in Windows 7.
