The ShelCustomUserOptions object manages the additional personal preferences in scripting, created as persistent variables in CUSTOMSHELL.vb. You can call it as:

<variable> = ShellCustomUserOptions.<preference>

An example:

If ShellCustomUserOptions.PLN_LastPublication > 0 Then

Define new persistent variable in CustomShell.vb

1.Open the add-in solution in VBExpress and then open Shell.VB.

2.Locate the following code:

<XmlRoot("SiteShellUserOptions")> _

Public Class ShellCustomUserOptions

  Inherits CustomUserOptions

3.On the appropriate position below it, add a new line such as:

4.<XmlAttribute()> Public <variablename> As <variabletype> = <defaultvalue>

where:

o<variablename> is an unique name for the persistent variable,e.g. PLN_LastPublication or something similar. .

o<variabletype> is one of standard VB.NET types, as String, Boolean etc.

o<default value> is the default value for the variable, until user changes it.

You need to specify all of the above.
