- Version: 1.2

- *** See Below for changes since First Release ***
-
- If all you want is a screen saver then copy RedTop.SCR
- to your Windows directory and PicClip.vbx to your Windows\System
- directory. You can then configure in in the Control Panel
- Program.
-
- For developers wanting to write their own Savers Read on....
-
- I have included the source code for RedTop to illustrate
- how simple it is to create screen savers in Visual Basic. You
- are welcome to use the code as a base for your own screen savers.
- The source code is fully commented and should be fairly simple to
- follow. I have tried to make it obvious where code is common to
- all screen savers and which is specific to RedTop.
-
- Please note that the Startup is via the main Sub in main.bas
- This decides which form to show, the screen saver or the
- configuration form. Screen Savers in general must be passed one
- of two parameters; /c for the configuration form and /s for the
- saver itself. For development this can be set in the Options
- menu of VB. Red Top maintains it's configuration details in the
- Control.ini file in section [Screen Saver.Red Top]. The
- password feature operates in exactly the same was as the
- standard Savers. However the code for encrypting password is in
- a Static library for C coders. As such it is not available
- directly to vb programmers. To get around this problem I have
- implemented my own, very simple, password routine which is kept
- in the ini file section as above. The implications of this is
- that changing the password in Red Top will only affect Red Top
- and not any other Saver. The converse is also true. One last
- thing to know is that when you "make exe file" your own Saver
- make the filename myscrsav.SCR and the application title
- "SCRNSAVE :My Screen Saver" Your Screen Saver will not opperate
- correctly if you don't. The Application Title after the colon
- is what it will be listed as under the Control Panel.

- Version History
-
-
- 1.0 (29-Sep-94) First Release
- 1.1 (14-Nov-94) Internal Version (Never Released)
- 1.2 (29-Nov-94) Enhancement Release
-
- Fixed Password validation to Uppercase. All new passwords are
- converted to uppercase. The Validation now being insensitive
- to case. Nb you may need to manually remove your old password
- after reinstalling this screen saver. Edit your control.ini file
- in the windows directory and change the following in the
- [Screen Saver.Red Top] Section
- Password=
- PWprotected=0
- This will remove your old password.
-
- Made the saver forms the Topmost form and System Modal. This now
- acts the same way as all other screen savers. That is, if you
- have the clock program as "Always on Top". Then it will not show
- through the screen saver. When the screen saver is finally turned
- off then the clock will revert to being "Always on Top". Making
- the forms System modal also stops you from getting out of the
- saver by alt-tab or ctrl-Esc etc.
-
- Added a timer to the Failed Password form so that it times
- out after 30 seconds, just like the enter password form.
-
- Added the Version field...
- I didn't think I would need this :->
-
- I remembered to include the Picclip.vbx control this time !
-
- Finally,
- Thanks to all those who have commented on Redtop, I hope you find
- that this new release will resolve all of the "features" of the
- first version.
