1.0 Online Help FIle

To help you understand the use of the WebExtract ToolPak controls
there is a online help file (Wbxtract.hlp) installed into the windows
system directory.  For NT3.51 and NT4.0 the help file it is under the
subdirectory system32.

------------------------------------------------------------


2.0 Sample Code - Projects

In addition to the help file, there are several Visual Basic 4.0 
projects that demonstrate how to use the controls.  The sample
code and project files are located in the directory 
C:\Program Files\Wbxtract (or C:\Wbxtract for NT3.51).  To view and 
run the samples, simply start VB4 and open the following projects:

	NParse32.vbp - shows how to parse text files
	NHTML32.vbp  - shows how to parse HTML
	NAlarm32.vbp - shows how to use the event scheduler (wildcard
                       times only are shown; fixed times are allowed)
	NTriever.vbp - shows how to download pages from the web

Please note that if you are running NT3.51, you must modify the
text in the sample applications to search for the sample file
in the directory c:\wbxtract instead of the defaulted 
c:\program files\webxtract.

3.0 WebExtract ToolPak Registered Version Installation

IMPORTANT: When installing the registered version of WebExtract
           ToolPak onto the development computer, make sure all earlier
           versions of the OCXs and especially the LIC files are 
           removed from the computer first. These files are 
           NHTML32.*, NParse32.*, NAlarm32.* and NTriever.*.
           Failure to do this may cause the LIC files to not be 
           copied during installation, leaving the developers only
           LIC files intact and being used, which will, of course
           continue to generate the unregistered error message.


The Most Common Issue After Installing The Registered Version:

Q. I've installed the new versions of the controls and I still
   get an error message when I run the EXE.
A. After installing the registered version of WebExtract ToolPak, 
   you must re-make any executables that were created with
   the developer-only license files.  The EXE file retains
   licensing information and if not recreated, it will contain
   the old value of the developers only license.
------------------------------------------------------------


4.0 NAlarm32 - Additional Information

NAlarm32 clears all alarms at midnight and then fires the
TimeChange event.  Care must be taken not to set any alarms
right before midnight, as they might not fire.  This may 
occur because the system may be busy performing some other
task.  As a concrete example, if you set an alarm for 
23:59:59 there is a small possibility that the system may 
become busy at 23:59:58++ and not allow the event to fire
at 23:59:59.  Typically, if this happens at any other time
of the day, the software will just fire it when the system
becomes "unbusy".  When this occurs at midnight, the new
time when the system becomes unbusy is after midnight.  NAlarm
will respond to the date rollover by clearing all alarms,
even the one that didn't get executed.

5.0 NParse32 - Additional Information

Q. How to add tab characters to delimiter string.
A. You may add a tab character by appending Chr$(9)
   to the Delim string.


------------------------------------------------------------

6.0 NT3.51 Issues

The installation application for WebExtract ToolPak installs
the OCX, Lic and Help files into the system directory,
typically Winnt\System32.  All documentation refers to the 
windows\system directory (ala Win95).  

The documentation also states that the sample code is 
located in the c:\program files\wbxtract directory. For
NT3.51, this should be the c:\wbxtract (only
Win95 and NT4.0 use the \program files\ directory).

Similarly, the sample applications that open files
(NParse32 and NHTML32) default to retrieve the sample
test file from c:\program files\wbxtract.  For NT3.51
you must modify the string in the textbox to use
just c:\wbxtract\....
