- Windows users just can't get enough control over the customization
- of their systems, it seems. The more they can change their
- personal setup, the more they want to change it.
-
- Personally, I think this is a good thing. Windows allows you to
- customize so many things -the colors, the applications you start up
- automatically with Windows, and so on - that it keeps you from
- getting too serious about the work you're really supposed to be
- doing on your PC.
-
- But one of the aspects of Windows that has been quite hard to
- manage is the automation of these customized features. In other
- words, you may want Windows to automatically display certain icons
- in Program Manager whenever you boot up your PC, but not when your
- children boot it up (determined, perhaps, by which batch file they
- run to start Windows). Or you may want the Program Manager to
- provide a certain group window when your PC or laptop is connected
- to a network, but not when it isn't connected.
-
- Fortunately, there is now a new shareware application that can help
- you automate almost any aspect of Program Manager groups. Even if
- you don't use the Windows Program Manager (because you prefer some
- other shell, such as Norton Desktop for Windows), this shareware
- application may give you ideas about how to automate various
- features of your own Windows interface.
-
- Managing ProgMan
-
- Before getting into the details of this shareware program, we need
- to understand a little bit about how to automate the configuration
- that comes up when we start Windows, and what the files are that
- make this configuration possible.
-
- The Windows Program Manager displays icons in a series of
- overlapping windows called group windows. Each of these groups may
- contain one or more icons, each representing a certain command
- line, working directory, and icon image.
-
- The file in which Windows stores the information about Program
- Manager group windows is called PROGMAN.INI. This file is described
- in the sidebar. PROGMAN.INI contains several lines that name other
- files, each of which defines the contents of a different group
- window. These files have the extension GRP. The Main group
- window, for example, is stored in a file named MAIN.GRP. The
- StartUp group file is STARTUP.GRP, and so on.
-
-
-
-
-
-
- If we could control the contents of PROGMAN.INI and all these GRP
- files automatically, several alternatives become possible:
-
- * By creating two different batch files to start Windows, one for
- yourself and one for your kids or co-workers, you can make a
- different set of group windows appear in Program Manager, depending
- on the level of trust you have in their abilities. You could make
- Program Manager, for example, show only those icons that represent
- games, while making invisible those icons that represent your word
- processor, file manager, and so on. If you let your kids use your
- PC, for example, this would allow them to click whatever they
- wanted, with no concern that they would accidentally delete your
- important files while playing.
-
- * If you run a network, you can make different group windows show
- up or disappear based on whether or not the PC is currently
- connected to a working network. You could use a batch file that
- simply looks for the existence of a common file on a network
- server, and then edits the Program Manager groups based on the
- results.
-
- You can probably think of many other cases in which you'd like to
- have a different configuration of Program Manager groups or icons,
- depending on the status of your PC (as determined by whatever
- utility programs you like to use).
-
- The Binary-to-Text Switch
-
- The new shareware application that gives you this kind of control
- is called Group-to-Ini (GRP21NI). This unwieldy name is a
- confusing label for what is really a very simple program.
-
- GRP2INI converts any Program Manager group (.GRP) file into a plain
- text file, much like WIN.INI, SYSTEM.INI, and other initialization
- files that Windows reads when it starts up.
-
- Once you have converted an unreadable GRP file into a plain text
- file, you can use another shareware application, Config Control
- (CFGCNTRL) to automatically edit it. This allows you to edit in
- various statements - or edit out statements you don't want - based
- on the findings of batch files that you use to start Windows.
-
- Finally, after you've made the edits you want via CFGCNTRL or
- manually (in a plain-text editor), you convert the text file back
- into the binary format that Program Manager requires of its .GRP
- files. When your batch file starts Windows, the Program Manager
- obeys the new GRP files and puts up on screen just those icons and
- commands that you put in your automation scripts.
-
- It sounds complicated, but once you've gotten the hang of it,
- creating different configurations on the fly can be easy and give
- you a tremendous amount of flexibility.

- A Tale of Two Batch Files
-
- For the sake of illustration, let's say that you want Windows to
- come up in one of two configurations. One will be for your kids,
- and is started from a batch file called KIDWIN.BAT. The other is
- for you and the other adults in your home or office, and is started
- from a batch file called BIGWIN.BAT.
-
- If all you want to do is make sure that the kids' configuration
- shows only the Games group in the Program Manager, this can be
- handled easily by Config Control alone. To make this happen, the
- KIDWIN.BAT batch file would call upon Config Control to edit
- PROGMAN.INI and "comment out" all references to groups other than
- GAMES.GRP. That way, when Windows started up, the Program Manager
- would show only the Games group window. Your other groups - Main,
- StartUp, and so on - would still be in existence, but would not be
- loaded by Program Manager. This makes these groups inaccessible,
- so your little ones can't fire up the File Manager and delete your
- C: drive, bless their hearts.
-
- To Network or Not to Network
-
- On the other hand, you might have a more complicated configuration
- problem in mind. One common example would be establishing a
- different set of icons in Program Manager depending on whether or
- not your PC or laptop was connected to a network when Windows was
- started.
-
- If a network was running, you might want a certain icon in the
- Network group to run a utility from the network server. If no
- network was detected, you might want the same icon to launch a
- different program located on the local hard disk of the PC.
-
- This situation would require that you start Windows from a batch
- file (whether AUTOEXEC.BAT or some other file) that detects whether
- or not a network is running. To do this, you might insert a
- command that looks for a particular file, which can only be
- detected if the network is up:
-
- IF EXIST N:\NETWORK\FILENAME.TXT GOTO NET
-
- A command like this could lead to a :NET section of the batch file,
- which would load GRP21NI to convert NETWORK.GRP into a text file.
- The batch file would then use Config Control to run a series of
- commands, which would revise the meaning of the icon in the Network
- group that you wish to automatically configure. INI2GRP would then
- convert the text file back into a GRP file. Finally, the batch
- file would start Windows, and Program Manager would come up with a
- Network group exactly as you had redefined it.
-
- Using GRP21NI and CFGCNTRL
-
- Because it is unwise to write a new GRP file while Windows is
- running - and because most of the configuration changes, in Windows
- should take place before Windows is started up Group-To-Ini and
-
-
-
-
-
-
- Config Control are DOS command-line programs. You use them like
- many other DOS utilities, by calling them from AUTOEXEC.BAT or
- other batch files to operate automatically on your Windows
- configuration, using whatever criteria you feel are appropriate to
- branch between two or more alternative configurations.
-
- You can download the unlicensed shareware files, G21.ZIP and
- CFGCNT.ZIP, from the PC/Computing forum. Once you get them, it's
- important that you peruse the documentation that accompanies these
- programs. Because they are DOS character-based programs, there are
- many options that are not apparent from simply running the programs
- at the command line. The programs are relatively easy to learn,
- but are powerful, so you'll want to know in advance how they work
- on your files. Be sure to make backup copies of your CFG files
- before you test these programs.
-
- To obtain a licensed copy, send $29 for Group-To-Ini, or $69 for
- both Group-To-Ini and Config Control, to TNT, P.O. Box 1791, San
- Ramon, CA 94583. For credit card orders, call 510-244-5449. TNT
- stands for "Tessler's Nifty Tools," a series of handy utilities
- that are described in the accompanying documentation files.
-
- If you need to automatically configure Windows on the fly, I think
- you'll find that these programs give you a degree of control that
- has previously been very difficult to achieve.
