The included components TUn??? can be installed using the steps above or
singularly.  Even though all TUn??? components were written as children of
ZipTV, they can also be installed and used seperately without the TZipTV
component.
  
  
  
  
  
Installing ZipTV Components for Delphi 2.0

NOTE: ALWAYS INSTALL ZipTV INTO AN EMPTY DIRECTORY!  DO NOT INSTALL
   INTO A DIRECTORY CONTAINING A PREVIOUS VERSION OF ZIPTV.
  
1. Select menu options "Component" then "Install".
2. Select "Add" then "Browse".
3. Select the directory where REGPACK.PAS resides.
4. Select the file "REGPACK.PAS" then click "OK" on each box that appears.
5. All TZipTV components will now be present in the "ZipTV" tab of the
component palette.
  
The directory containing RegPack.PAS must be included in Delphis' Component
Library Search path.  To alter this path, see Options|Environment|Library.
 


  
  
Installing ZipTV Components for Delphi 3.0

NOTE: ALWAYS INTALL ZipTV INTO AN EMPTY DIRECTORY!  DO NOT INSTALL
   INTO A DIRECTORY CONTAINING A PREVIOUS VERSION OF ZIPTV.


1. First compile the package.  In Delphi select File/Open and open the
   file TZipTV.DPK located in the directory the package was installed
   in.  The package dialog box will display with names of all components.
2. Select Options (menu)
3. Select Global  (tab)
4. In the 'Library Path' field, remove the directory to any previous
   version of the ZipTV component package.
5. In the 'Library Path' field, add the full path to the directory where
   ZipTV components were installed.
6. Press OK.
7. Select Install (menu).  This will compile the package and register all
   of the components in the Delphi IDE.  There may be some warning messages,
   ignore these... these are just notifications of implicit imports of files
   used by the registered components.
8. Close the dialog box.
9. You will be prompted to save the TZIPTV.DPK file.  Select Yes.

BE SURE THAT THE DIRECTORY WHERE ZIPTV WAS INSTALLED IS INCLUDED IN DELPHIs
'LIBRARY PATH'.  IF THE DIRECTORY IS NOT INCLUDED IN THE LIBRARY PATH,
DELPHI WILL BE UNABLE TO COMPILE.
  
  
Installing upgrade versions of ZipTV components
  
If installing the package to the same directory that contains a previous
version of ZipTV, delete the entire contents of the directory.  Unpack the
upgrade version into this directory.  In Delphi 2+, select the "Component"
menu option, then select sub-menu item "Rebuild".
  
Since the helpfile is also revised when features are added to the component,
always merge the new help file as is described in the following section.  If
this step is skipped, an error message will occur when pressing F1 on the
component or in the object browser, with a notification that the help topic
does not exist.
  
As we go through the development process, event parameters may change from time
to time.  When installing upgrade versions with these changes, Delphi will
respond with an error message, because these event procedure parameters no
longer match that of your code.  To correct this, allow Delphi to remove the
incorrect reference when the message appears and return to the object inspector
and double click the blank event definition.
  
  
  
  
  
Merging TZipTV.HLP into the Delphi help facility (Delphi 2).  
  
To install TZipTV.HLP so help can be called while in Delphis' Object Inspector
on a specific property when the F1 key is pressed, the keyword file
(TZipTV.KWF) must be merged into Delphis' master index file (DELPHI.HDX).  To
do this, follow the few simple steps as follows.
  
1.  *Unload Delphi if loaded.  
2.  Run HELPINST.EXE.  (Located in the Delphi\help directory).  
3.  Within the HELPINST program... select Options|Search Paths.  
4.  Select File/Open  
5.  Load the DELPHI.HDX file.  (usually found in the Delphi\bin directory)  
6.  If ZIPTV.KWF already exists, delete it.  It'll have to be reinstalled.  
7.  Enter the search paths where Delphis' help files are located(...Delphi\help
directory).  Append a semicolon to the end of this path and add the dir where
TZipTV.KWF can be found.   Be sure all files listed display a directory (this
acknowledges the help file was located), before continuing.
8.  Select Keywords|Add Keyword File.  Search for TZipTV.KWF (in the directory
ZipTV was installed).  When found press OK.
9.  Select File|Save.  (in the status bar, you will see: Saving & Compiling
Delphi.HDX.  
10. The keyword file (TZipTV.KWF) should now be merged into Delphis' help
environment.  
  
  
Once the keyword file has been merged into the Delphi master help index, Delphi
will be able to search for help with properties and events by pressing F1
within the Object Inspector.  However, unless the new help file is on the
current path, Delphi will not be able to load the help file.  There are two
options to resolve this.  First, move the help file to a directory on the
current path.  A good place is the Delphi\Bin directory.  The second option is
to add a line to the 'Files section' of the WinHelp.INI file located in the
Windows directory.  Each entry in this file specifies the location of a help
file.  For example, each entry has the following form:
  
TZipTV.HLP = <full path>  
  
...<fullpath> indicates the directory where the file is located.  
  
Note: the DPK file as well as the DCR files have been included in the package.
The DPK file allows recompilation of the package.  The DCR files contain the
pallette icons.
  
  
  
  
  
Installing TZipTV.HLP into the Delphi help facility (Delphi 3).  
  
1. Copy the TZipTV.HLP & TZipTV.CNT files into Delphi 3 help directory.  If
Delphi was installed using the default paths, this directory should be
\Program Files\Borland\Delphi 3\Help.
  
2. Add the following line to the file Delphi3.CFG (in the "Third Party Help"
section).  Be sure to include the colon.  This file is also found in Delphi's
help directory mentioned above.
  
:Link tziptv.hlp  
  
3. In the same directory you will find a file named Delphi3.CNT.  Add the
following line (in the "Include Section")
  
:Include tziptv.cnt  
  
4.  Now when you press F1 in the Object Browser on one of the ZipTV components,
the help topic will be displayed.
