Locale-specific numeric format problems in web module.

Version affected: v1.5 with LMSAPI upgrade.

Symptoms:

On a system set to a locale where a comma is used to 
represent the decimal separator in a real number (France 
or Germany for example), scores which include a fractional
part are not saved.

Cause:

With version 3 of the AICC standard, a fractional part is
allowed for the score and time sent from the lesson to WBT
Manager. The upgrade to version 1.5 which adds the
AICC/SCORM API also adds support for these fractional
numbers. The AICC standard does not include support for
local number formats. A period is always used for the
decimal point in data elements which allow a fractional
part (score.raw, score.min, score.max, time).

The web module takes it's number format settings from
the default Locale setting created when NT is installed.
If that locale uses comma for a decimal separator then 
the WBT Manager web module will discard numbers containing
a period as the decimal separator because they are not
valid numbers.

Fix:

The WBT Manager Web Application DLLs have been modified 
to use number conversion routines that always use a period 
for the decimal separator.

1. Make sure that the LMS API upgrade is installed. It is
available at: www.ielearning.com/wbt/support/files/lmsapi10.zip.

2. Unzip the patch files into a temporary directory. The zip file
contains: wbtman2a.dll, wbtman2b.dll, wbtman2c.dll, wbtman2d.dll,
wbtman2f.dll, wbtman2g.dll (new file versions are 1.502).

3. Locate the existing copies of the DLLs on the web server. They 
should be in \winnt\system32.

4. Stop the web service to release the existing files. Enter:
	NET STOP IISADMIN
at the console prompt while logged onto the web server as 
Administrator.

5. Replace the existing DLLs with the new ones.

6. Restart the web services (NET START W3SVC). Use the services
applet in the control panel to re-start FTP and SMTP if desired.

All Done!

Also fixed in this patch:
	
Unlimited license not allowing web administrators to add students.
	Reset stats not copying min/max score to history.
