- DISCLAIMER:
- ===========
-
- This utility mucks with the registry and as such can do great harm to your NT
- setup if not used with care, perhaps even rendering your system unbootable.
- While I have made every attempt to verify the correct operation of this
- utility, I will not accept any responsibility for damages done to your
- hardware, software, or phyche as the result of using this utility or software
- based on this utility -- the user will accept all responsibility for any
- undesirable effects of this utility. Fair enough? If not, remove this utility
- from your system.
-
-
- Why So Serious?
- ===============
-
- The disclaimer above is so serious because the registry is to NT what our
- long term memory is to us. If you twiddle the wrong bits in either one, you
- could do serious damage. So please, becareful with this utility.
-
-
- What's It For?
- ==============
-
- As the author of PTerm, I came to a point when I decided to add the ability
- for PTerm to play a wav file when finished uploading or downloading. At first
- I was going to design a dialog box which the user could pop up to set the
- sounds s/he wanted played. Then one day I was in the control panel 'Sound'
- applet when I noticed that there were two application entries which the user
- could set sounds for (in addition to the system sound entries), one for MS
- Mail and one for Schedule+.
-
- I started thinking that it would be nice if I could add a couple of fairly
- generic entries in there for PTerm, one for a completed download, and one for
- a completed upload. I looked in the registry for where the list of sounds
- were kept and figured out the format. I then went looking for a small utility
- which I could place in a batch file to automatically add the new entries in a
- users registry -- there were none, at least none which I could figure out how
- to use.
-
- I didn't want to leave the user to starting up REGEDT32 and mucking around
- with that, so I wrote Reguser. Its called RegUSER because it can only be used
- to add/change registry values in the HKEY_CURRENT_USER tree.
-
-
- Operation
- =========
-
- Since we have been talking about its use for PTerm, I will continue with that
- line of thought and use it as the example.
-
- Ok, we see that in the HKEY_CURRENT_USER tree there is a path to the sounds
- called:
-
- Control Panel\Sounds
-
- We would like to add a couple of values to this key, one called
- AppDownloadCompleted and AppUploadCompleted. The format of these values is
- REG_SZ, which means they are zero terminated strings. This brings up an
- important limitation of Reguser -- it can only add/modify values of type
- REG_SZ. If you try and change a value which is not REG_SZ, changes are
- Reguser will change the type to REG_SZ and this will cause you grief.
-
- The exact format for a sound entry is:
-
- Control Panel\Sounds\SoundValueIdentifier = sound.wav,List Entry String
-
- Lets look at an example, like the sound played when new MS Mail arrives:
-
- Control Panel\Sounds\MailBeep = ding.wav,New Mail Notification
-
- Alright, "MailBeep" is the the identifier which MS Mail will use to retrieve
- the sound to play when new mail arrives. "ding.wav" is what the sound is
- currently set to. "New Mail Notification" is the string which shows up in the
- list box when the control panel "Sound" applet is run.
-
- With that in mind, here are the command lines for adding the two values we
- need for PTerm's sound support, setting the sound to none for now:
-
- reguser "Control Panel\Sound" AppDownloadCompleted "<none>,Download Completed"
- reguser "Control Panel\Sound" AppUploadComplete" "<none>,Upload Completed"
-
- You can see that Reguser takes three parameters -- the path to the key for
- which a value is to be changed/added, the name of the value to add/change,
- and what to set the value to. Note that anytime one of the parameters needs
- special characters like spaces, angle brackets or commas, you must enclose
- the entire parameter in double quotes.
-
- After executing these two commands the user can fire up Control Panel and
- open the Sound applet, and s/he will see in the list of available sounds to
- set both "Download Completed" and "Upload Completed" which they can change
- from "<none>" to be any sound on their system.
-
- If Reguser is successful in adding/changing the value it will indicate as
- such, otherwise it will indicate an error.

- Source Code
- ===========
-
- The source for this utility is included in RGUSRSRC.ZIP. If you make any
- enchancements to Reguser, please send me a copy, and try to retain backward
- compatibility if possible (i.e. keep the first 3 parameters the same for
- instance).
