Syntax

Visual Basic
C#

'Declaration
 
Public Function GetControlsByName( _
   ByVal name As String _
) As Object()

'Usage
 
Dim instance As Application
Dim name As String
Dim value() As Object
 
value = instance.GetControlsByName(name)

public object[] GetControlsByName( 
   string name
)

Parameters

name: The name of the control. To get all unnamed controls, enter an empty string.

Return Value

An array of controls that match the specified name. If an empty string is passed as the name, an array of unnamed controls is returned.

Exceptions

Exception	Description
System.ApplicationException	The API service does not intialize successfuly.

Remarks

This method returns a collection of controls that have names that match.

Initially, the name of a control is an empty string. It can be changed to any text string for future control identification. The name might not be unique among all running sessions and is not saved in its session configuration file when the control is closed.

Example

This sample shows how to get all of the unnamed controls running in an application instance.

//This sample gets all of the unnamed terminal controls running in an instance of InfoConnect.
//Before you run this sample, make sure at least one session is running in an InfoConnect workspace. 
//If more than one instance of InfoConnect is running, the session must be running in the first instance that was started.
