ClipHelp (C) Version History
Ver 2.2 - 3 April 1992
Optional ability to call a UDF on accessing help (a 'pre-help'
UDF) and/or another on leaving help (a 'post-help UDF') via public
variables in Summer 87 version and code block parameters in
Clipper 5 version. Scope for imagination!
Fixed bug in both 2.1 vs libraries whereby help screens overlaid
a junk background when ClipHelp was used in mono mode.
Facility for users to access full ClipHelp editor features through
the use of a serial number and code supplied by CISMail, FAX,
phone or airmail on registration. Serial numbers and codes will
also give users access to full features of future versions of
ClipHelp downloaded from Nanforum or a local BBS.
Ver 2.1 - 17 February 1992
Maintenance release. Corrects an omission in CLHLP501.LIB whereby
changes to the Application Background attribute made with
ClipHelp's 'Set Defaults' option were being ignored.
Ver 2.0 - 3 January 1992
ClipHelp .OBJ files in earlier versions now replaced with .LIB
files.
GrabScreen() added to CLHLPS87.LIB and CLHLP501.LIB.
Incorporating appropriate calls to this function during
application development enables whole or specially-defined part
screen images to be saved to a database called CAPTURES.DBF
(created and maintained by ClipHelp). The same function can be
called in ClipHelp's 'Edit Colors' option to 'cannibalise' parts
of its help file as it is creating it.
Images saved in CAPTURES.DBF can be inserted directly into the
HELP.DAT file complete with color attributes using the new
'Import' facility of ClipHelp's 'Edit Colors' option, greatly
reducing the work needed with previous versions of ClipHelp.
The attribute bytes of all characters not obscured by overlaid
help data when <F1> is tapped are now changed and restored on
return to the application. This avoids unsightly flashing panels
which could previously arise with Clipper 5's SETBLINK(). The
default color can be changed using ClipHelp's 'Set Defaults'
option.
An optional 'path' command line parameter when running ClipHelp
tells it where to find HELP.DAT and HELP.TXT files, supporting
concurrent development of help systems for multiple applications.
Public variable in Clipper S87 version and additional parameter to
the solitary function call in Clipper 5 version optionally allows
HELP.DAT and associated files to be located elsewhere than in an
application's default sub-directory.
Ver 1.11 - 12 December 1991
Checks whether a mouse is in use and if so, saves the condition,
turns off the mouse while help screens are displayed and restores
the original mouse condition on exit.
Ver. 1.1 - 24 October 1991
Replacement Clipper 5 OBJ module (CLHLP501.OBJ). All PUBLIC and
PRIVATE variables removed and replaced with LOCAL or file-wide
STATIC variables. Only one line of source code need be added to a
Clipper 5 application to embrace all ClipHelp facilities. Context
sensitivity achieved by calling a function to pass a string/code
to ClipHelp, avoiding a PUBLIC variable declaration.
Replacement Clipper 5 C function library (HLPC501.LIB) with
improved speed over that supplied with version 1.00.
Ver. 1.0 - 4 July 1991
