HOWTO: Custom VBScript Code - Check for Bank Holiday (kb2285)
The information in this article applies to:
- Graphical Script Editor v4.00
- SwyxIt! v4.00
- SwyxWare v4.00
With SwyxWare v4.0 it is possible to define own custom scripts with the Graphical Script Editor (GSE). To create scripts using the GSE you have to license the Option Pack - Extended Call Routing.
This articles describes, how to implement a simple Bank Holiday Check using a text file defining the bank holidays.
Note: an updated version of this script is available on the public Swyx Forum website www.swyx-forum.com. This new version allows beside simple days also times and date/time ranges in it's bankholiday definition file.

Installation of the example rule
Download the complete example code usig the link at the end of this article and copy all included files into the
c:\gse_demo To load the BankHoliday.rse file as rule into your Call Routing Manager i.e. Graphical Script Editor please follow these steps:
- Open the Call Routing Manager.
- Click the New... button.
- Select Graphical Script Editor and click on Ok.
- Within the GSE open the File | Import... menu.
Select the BankHoliday.rse. The rule will be imported and your GSE will look like this:
- Save the new rule using the File | Save menu.
- Close the GSE.
Copy the file BankHoliday.txt into the global script folder
C:\Programme\SwyxWare\Share\Data\PhoneClient\ScriptsUsing this folder ensures all other users to be able to access it also. The file contains all bank holidays in Germany being valid for all federal states until end of 2005.
Activate the rule by moving it to the right list box of the CRM.
How it works
Custom code can only be added to the Start rule. All consts, variables and functions you'll define here are available all over the script, i.e. can be used in all blocks e.g. the Evaluate block. Please note, that the final script being created by the GSE places the VBScript statement option explicit to the top of the script. This forces all variables to be used within the script to be declared properly.
As you will see in this example a function will be defined within the custom code in the Start rule, which will later be used within a Evalute block.
The function IsBankHoliday() checks if a given date (it will be called with the current date) is defined within the BankHoliday.txt file and return accordingly True or False. This is how the code looks like:
After activating this rule there will be played a "beep" on incoming calls if it is a bank holiday. This "beep" is a placeholder, of course, for your own script.
The definition file
Within the file BankHoliday.txt all bank holidays have to be listed where each date takes its own line. The date format must match to your regional settings on the SwyxServer machine. This example assumes a date format dd.mm.yyyy.
Please note that this file contains all german bank holidays being valid for all federal state until the end of 2005.
All callrouting scripts, and therefore also your code, runs under the SwyxWare Service Account. Please make sure that this account has the needed priviliges to access the file/database.
The script in this example does contain no Error Handling. If an error occurs at runtime, e.g. when trying to access a database, this error will not be handled, the script will stop and the call get lost. If you have enabled Server Tracing for SvrScript on level Info3 you will find the original Microsoft Script Engine error message within the server trace file.
To get your own error handling you have to disable the standard error handling by the Script Engine:
