Dynamic Environment Variables

Dynamic Environment Variables are very similar to the functions available in Dynamic channels and Dynamic Infoclientvalues. The syntax in the text contains a wildcard-expression, which defines the information, for which the Infoclient has to query for. The result of the query then will substitute the expression in the text that is displayed on the client.

 

Syntax:

 

%DICV(diType,diValue)%

 

The expression begins and ends with the % character. Inside the expression is a function-call: DICV(diType,diValue). This function queries for certain client properties. The first argument diType must be replaced with a static keyword for the type of information, that you want to query for. The second argument diValue must be replaced by a value, which is accessible for the type. For a list of possible types and values, please see chapter Dynamic Infoclientvalues.

 

These attributes can be defined and checked:

 

•Applications (installed)

•Processes (running)

•Connections

•Files (Existing)

•Titles of windows

•Registry

•Data attributes

•Inifiles

•WMI Query

 

Example:

 

Your Operating System is: %DICV(diWMIValue,SELECT Caption FROM Win32_OperatingSystem)%

 

This Dynamic Environment Variable will search for the name of the client's operating system. The result will replace this expression in the message displayed on the recipients screen.

 

 

Dynamic Infoclientvalues

 

The query of the client properties is done by means of dynamic Infoclientvalues, a special form of Ini entries.

 

How to add a dynamic Infoclient Value (DICV) to an Infoclient is explained in chapter Allocate Clientproperties.

 

The following types of dynamic Infoclientvalues ​​are currently available for query:
