Checks, whether the context parameter with the specified name already exists.

bExists = Object.Exists(Name)

Object	ContextParameters Object with this method
Name	String Specifies the name of the context parameter.
bExists	Boolean The value is TRUE if the context parameter with the specified name already exists.

The following example generates a set with two context parameters and checks, whether the StringParameter context parameter already exists:

VBScript

Python

Copy script

Dim oMyDataStore
Set oMyDataStore = Navigator.ConnectDataStore("MyASAMServer")
'Generating parameter set
Dim oMyParameterSet
Set oMyParameterSet = Navigator.Settings.CreateContextParameterSet
oMyParameterSet.Name = "MyParameterSet"
'Generating parameters and writing parameters into parameter set
Dim OMyParameters
Set oMyParameters = oMyParameterSet.Parameters
Call oMyParameters.Add("DoubleParameter",1.2345,DataTypeFloat64)
Call oMyParameters.Add("StringParameter","Parameter",DataTypeString)
'Checking if parameter exists
Call MsgBoxDisp(oMyParameters.Exists("StringParameter"))

oMyDataStore = dd.Navigator.ConnectDataStore("MyASAMServer") 
#Generating parameter set
oMyParameterSet = dd.Navigator.Settings.CreateContextParameterSet() 
oMyParameterSet.Name = "MyParameterSet" 
#Generating parameters and writing parameters into parameter set
oMyParameters = oMyParameterSet.Parameters 
oMyParameters.Add("DoubleParameter",1.2345,dd.DataTypeFloat64) 
oMyParameters.Add("StringParameter","Parameter",dd.DataTypeString) 
#Checking if parameter exists
dd.MsgBoxDisp(oMyParameters.Exists("StringParameter"))
