*** 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.
