Removing MRU Files from Windows Applications

A number of weeks ago, I was asked if I knew how to remove the names of the most recently used files which appear in many applications when the 'FILE' menu item is selected. I have discovered two magazine articles which together contain the answer along with some other interesting facts.

The first is in PC Magazine, November 4 1997, Vol 16 No 19 in the User to User section, and is entitled 'Automatically Remove Entries from the Registry'. The second is in the 3 November 1998 Vol 17 No 19 issue. This one, also in User to User is called 'Automating Deletions from the Windows 95 Registry/.

Before we start: .... A WARNING!!.....

Playing around with the Windows Registry has always been considered hazardous, because of the possibility of accidentally changing something in an unknown way, and rendering some program unusable, or even worse, your computer unboot- able. Before you start, therefore, make a backup as follows. Run 'RegEdit', and select the Registry branch you plan to modify. In this case it will be HKEY_CURRENT_USER. Select 'Export' from the registry menu to create a .REG file defining that branch. Give it a name you will recognize again, such as 'HKCUBackup'. The system will put a .REG extension on it. If you blow HKEY_CURRENT_USER, you will be able to replace it by calling 'RegEdit] again, and selecting 'Registry | Import Registry File'. Then you select the backup file you created. RegEdit will put it back together again.

You should remember that the Registry is dynamic. If you make a backup, and then you delete or add a new application, the Backup will no longer be valid if you use it. You should have a fresh backup for each manipulation of the registry. Of course, once you have tested the files which I will show you, there should be no further hazard until you want to make new changes.

The articles noted above give examples of .INF files which are used to alter the Registry. The file in the second article shows how to delete the contents of the URL list in the 32 bit version of Netscape Navigator 3. It can be copied from the article, or down loaded from PC Magazine's web sight. It contains these lines:

;DELURL.INF ; When 'installed', this file deletes the 'URL History' ; key in the Win 95 Registry, along with all values ; (URLs) associated with the key. [version] signature="$CHICAGO$" [DefaultInstall] DelReg=EraseThis [EraseThis] HKCU,'Software\Netscape\Netscape Navigator\URL History' ;HKCU is Win 95 'shorthand' for Hkey_Current_User.

Note that in an .INF file, lines preceded by a semicolon are remarks, and are not acted on. The key line is under the [EraseThis] header. This is the line that can be altered to adapt the file to other erasable items. Of course, you would probably want to change the comments as appropriate. You can also leave blank lines for better readability.

This file deletes the contents of 'Software\Netscape\ Netscape Navigator\URL History', under the HKEY_CURRENT_USER branch of the Registry. The .INF file is activated when required by executing a batch file. (Remember DOS .BAT files?) You need to create a batch file to call the .INF file, or you may have a batch file to which you can add the new instruction.

Directions for making the new instruction for the .BAT file are as follows: Open the Windows Explorer. Click View | Options, Select File Types, From the list of Registered File Types, highlight 'Setup Information' and click the Edit button. In the Actions window of the Edit File Type box, highlight Install, then click the Edit button. In the box labelled 'Application used to perform action' you will see a highlighted string. BE CAREFUL, if you hit any other key you may delete the highlighted string, and then you will have to start over again. Use CTRL-C to copy the string to the clipboard, and the back out of Explorer by cancelling all the way. I made a new folder on my C: drive to put this stuff in. I called it RegControl. Then I made a new file which I called DeleteURL.BAT. It has the following lines in it:

rem DeleteURL.bat C:\WINDOWS\rundll.exe setupx.dll,InstallHinfSection DefaultInstall 132 C:\RegControl\delurl.inf rem This will delete the Most Recently Used list from the Netscape Navigator

Notice that the second line is pasted from the Clipboard, and is followed by a space and then the complete path of the .INF file. The first and third lines beginning 'rem' are remarks. They are informative only.

If you have not already made your Register backup (which you really should have done) be sure to do it now, and then test the system by executing the .BAT file. Double clicking it in the Explorer will do the trick. When it works OK. You can call the .BAT file from your autoexec.bat, or other file, or you can incorporate the lines into another batch file.

Finding the correct place to apply this technique for other applications is a bit of a trick. I used RegEdit to explore the Registry until I found the place where last used files for Corel WordPerfect are stored. It is in HKEY_CURRENT_USER at 'Software\Corel\User Assist\8\Recent Work\WordPerfect\Last Opened'. When I first typed this into the INF file, and saved the file under the name WPMRUDel.BAT, it did not work. I found I had left out the space between 'Last' and 'Opened'. Windows doesn't care if letters are upper or lower case, but spaces are characters in long file names, and are important. No harm can come of a mistake like this since the file cannot delete something that does not exist, unless of course, it is the wrong one, and it does happen to exist.

It only needs to be added for completeness, that this technique, using appropriate commands can be used for making all sorts of changes including additions of data to the Windows Registry.

Bios Upgrade

I'm going to relate here an experience I encountered partly out of desperation and partly out of curiosity. The story starts with two motherboards - one with a 'dead' BIOS and the other with a toasted i/o sub-system and bad voltage regulator.

Now the board with the bad BIOS was fine with the exception that it wouldn't boot. I could replace the BIOS chip with a known good working one, but then I'd have another good motherboard missing a BIOS chip. So what to do? I had a motherboard that someone had dropped a steel slot cover across several chips, and then powered the computer on and off a couple of times. Needless to say, the motherboard smoked!

Since the BIOS is really only used to power up the system, why not power on with a good BIOS chip, then once it's booted up, replace it 'hot' and then try to flash upgrade the old and dead BIOS chip? Sounds good in theory, but aren't there risks with removing parts and pieces while the computer is running? Of course there are! (re-read the first para).

To start this 'experiment', I did a clean boot with a DOS disk after making sure that the BIOS chip was very loosely set in it's socket. Once booted into DOS, I carefully removed the BIOS chip and replaced it with the dead chip while maintaining strict ESD precautions. So far so good. The computer is still running with at first a good BIOS, no BIOS and then a dead BIOS. So as not to push my luck too far, I now started to run the flash BIOS routine. Once that's done, the program asks me to reboot. Now the question is, will it reboot under its own steam? Did the BIOS flash work? But of course!

My co-workers didn't believe that it would work (I think they thought I was joking when I said what I was going to do) and my boss didn't believe it even after seeing it work! I wouldn't suggest this approach as a regular way of fixing dead BIOS chips, but given the right circumstances, (desperation) it may do the trick. Please don't take this procedure as advice, and as usual, there are no guarantees to this method. Kids, don't try this at home!

Networking: Upgrade that makes sense

First came 'sneaker networking' in the late '70s, early '80s, when we carried floppy diskettes from computer to computer. Then came 'poor-boy networking', using simple switches, null modem cables, software like LapLink, and MacLink to share printers and transfer files. Often we simply plugged and unplugged cables. Macintoshes had the advantage of built-in network capabilities, although at just 230.4 Kbps transmission speed was slow.

I tried all of the above during the 1980s in my home office and as a partner in a small, pioneering publishing service bureau. A "real" network, with servers and client workstations, was out of reach.

Things have changed! Low prices, simple peer-to-peer networks, and support built into current operating systems now make it inexpensive and easy to link computers and peripherals in home or small business offices. Today you can enjoy the benefits of a true Ethernet network for under $100 if you run Windows for Workgroups (3.1.1); Windows 95, 98 or NT; or Mac OS (and want more speed than AppleTalk provides).

Adding a simple network is especially attractive if you are adding a new computer. Don't get rid of your old one. You won't get much for it, and it can still be a useful asset. How? By linking it to the new computer via a simple network. Consider these possibilities.

First, you can keep all your pet programs, especially 'legacy' 16-bit Win3x and/or DOS apps, on the older machine and use them as you always have. Use only 32-bit software on the new computer to improve performance.

Second, you can eliminate duplication of programs. Why invest in a new word processor or spreadsheet, for example, if the ones you've been using still do everything you require? Save your new machine for up-to-date graphics, games or Internet-related programs that really benefit from better performance.

Third, you can use each of the two computers to back up the other one. John Bowen, honcho of the Black Lake Computer Club, Nipomo, CA, showed me some months ago how he and his wife do just that with their His & Her computers. It's probably the easiest way to do backups.

One thought here: If your old computer has its hard drive(s) filled to bursting, consider adding another one just for backup use. New multi-grg hard drives are really cheap now, and I suspect it's possible to find decent used 1.2 to 2.5 gigabyte drives for $25 to $50. (Part 3 of this Upgrades that Make Sense series will zero in on hard drives, incidentally.)

All you need to set up a network are the following:

* A Network Interface Card (NIC) for each computer and appropriate driver
* Thin coaxial or unshielded twisted pair (UTP) cabling in appropriate lengths
* BNC connectors and terminators, if you use coaxial cables
* Multiport hub, optional if you want to connect more than a handful of computers, necessary if you want a Fast Ethernet network (100 Mbps vs. 10 Mbps for standard 10Base-T Ethernet), which is probably overkill for most of us.

Prices? Very reasonable! I've seen full-duplex, Plug-and-Play Ethernet cards for as little as $15 to $20; 5-port hubs run from about $40 to $100.

UTP 10Base-T cables resemble ordinary telephone wire but use RJ45 connectors and have eight wires inside. Coaxial 10Base-2 cables look like those that connect TVs to VCRs, with similar twist-on BNC connectors. Prices vary by length, but a 10-footer typically sells for about $11 to $14 for either type. Use cables that meet Category 5 standards to ensure top performance and future expandability. For networks with more than a few computers or when using Fast Ethernet, experts recommend UTP cabling.

To connect just two computers, it's often cheaper and easier to buy a kit that includes two NICs, a 10Base-2 coax cable, connectors and terminators, driver setup software and detailed installation instructions. This is especially true for novice networkers. With a kit, you're sure that components match, and you have a single source to contact should you need tech support.

You can add one or two computers to this type of network later, daisy-chaining them with additional NICs and cables. Use a hub and UTP cables for bigger networks.

I've used the LinkSys (www.linksys.com) Network in a Box and StarTech Computer Products (www.startechcomp.com) Network Kit (under $100) and they worked well.

Make sure the NICs have both BNC and RJ45 connectors so you can upgrade to twisted-pair cables if you deiced to add a hub and expand your network later. I haven't tried Netgear's starter kits (about $120) that uses UTP cables and a 4-port, externally powered hub, or a similar one from Linksys (two PCI NICs, 5-port hub, about $95), but both are attractive, expandable options.

My entry to networking in 1996 came after buying a new HP inkjet printer designed for use with bidirectional parallel ports and IEEE-1284 cables. We already shared two printers, using A-B switches. I couldn't find a switch that was compatible with the IEE-1284 standard, and I tried! Installing a network was the farthest thing from my mind, until I spotted Network in a Box from LinkSys. It looked simple enough (though I had grave misgivings) and the cost (then about $90, now under $70) was less than some of the switches I priced.

Physical installation was easy. Pilot error (I misread a key direction) created a few problems with the software setup. A little help from my friends at ASC Computers, my local computing life support system here in Woodland Hills, CA, solved that. Life instantly became much easier. My wife and I had easy access to the printer sand each other's files. If I was working on a newsletter and needed a graphics file Liz created, it was a snap to import it from her computer.

I'm currently nearing the final stage of a major system overhaul, including one new computer as a server, upgrades to three others, adding another printer, and new modems. Instead of having just two computers linked I will have four on the new net via a 5-port 10BaseT hub and UTP cables. I'll fill you in on that project in a future column.

A message from the Vice Chairman

The HAPCC has two kinds of meetings. Firstly the regular Sunday night meeting which most members attend regularly, secondly the monthly (approximately) planning meeting which organises the business of the Club, including what happens on the Sundays. The planning meeting is held on Monday, a week after the regular meeting in which all members of the Club are urged to attend. At the planning meeting, we discuss feature speakers for regular meetings, finances, membership, training, and other computer related subjects.

A word of thanks to guest speakers and the their web sites.

Our guest speaker at the March meeting was Mr. David Baxter, Product Specialist at MT&T for the MpoweredPc service. His multi-media presentation showed us how far the service has come, and in which direction it is heading. MpoweredPc was being officially launched on April 7, 1998 and it promises to be a serious contender in the high-speed internet/software on demand arena. More info can be found here: Mpowered. Once again, Thank you to MT&T and David Baxter.

Our guest speaker in February was Sgt. Bill Cowper, Internet Communications Officer of the Halifax Regional Municipality Police Department. He gave a history of how and when the police department started using the Internet. They were the first police department in Canada to be on the Internet. Sgt. Cowper is continually receiving calls from all over the world looking for assistance. The presentation showed how well the department and the officers in the patrol cars are versed on getting the criminals off the streets. If you would like to check-out their web site the address is Halifax Regional Police Service gives an idea of what an "Internet Cybercop" is all about.
