Getting Terminal Controls and Views

You'll need to create or get handles to InfoConnect terminal controls and views for most of your applications:

A Terminal control represents the data aspect of an opened InfoConnect document and can take many forms, such as an IbmTerminal or WebControl.
A View is the visual aspect of a session document required to display a session. One way you might consider the View object is to think of it as a tabbed view in the InfoConnect workspace.

Refer to the following tables for ways to get and create terminal (control) and view objects.

Getting Terminal Controls

The following methods can be used to get a handle to an existing control or to create a new control.

Use this API call	To get
GetControlsByFilePath()	A collection of open terminal emulation sessions. This method requires the path to a saved session document and returns a collection of all open emulation sessions that were created from that file.
GetControlByInstanceId()	An open terminal emulation session. This method requires the session's instance ID. A unique instance ID is created for a session each time you open the session document.
CreateControl(filePath)	A new terminal emulation session by specifying the file path for an existing session document.
CreateControl(Guid controlType)	A new terminal emulation session. Each session type requires a different GUID controlType. 3270 (IBM): Guid("{09E5A1B4-0BA6-4546-A27D-FE4762B7ACE1}") 5250 (IBM): Guid("{AF03A446-F278-4624-B9EF-C896DF2CA1CA}") UNIX and OpenVMS (OpenSystems): Guid("{BE835A80-CAB2-40d2-AFC0-6848E486BF58}") ReGIS Graphics (OpenSystems): Guid("{C62BA7E4-5A20-4681-931B-07BF7C971D13}")

Getting Views

Each of the following methods gets the View object associated with a control.

When using this method	Provide this parameter
GetViewByTitleText()	The Name property from the Tab Properties dialog box of the session document view. For example, GetViewByTitleText(MySession.rd3x). Note: To open the Tab Properties dialog box, right-click the session tab in the InfoConnect Workspace and choose Properties.
GetViewByInstanceID()	The API tab identifier number in the Tab Properties dialog box of the open session document. Each time you create a session document view, a new number is generated. (The API tab identifier of a View is different from that of the embedded control.)
GetViewsByFilePath()	The path to which the session or Web page document has been saved.

Note: To re-create a View object after closing it, you must first re-create the control that will be associated with the View.

Getting the View that has Focus

This sample gets the host session document that has focus in the InfoConnect workspace by getting the view object for that session.

Note: This program works only with host session documents; not Web page documents.

In InfoConnect, create an IBM session and an Open Systems session and save these sessions as mySession.rd3x and mySession.rdox in the default folder. (...\myDocuments\Micro Focus\InfoConnect.)
In Visual Studio, create a new Console Application project and add references for the following InfoConnect assemblies. (Depending on your version of Visual Studio, these can be found either on the .NET tab or under Assemblies | Extensions.)

To test this project

Close all instances of InfoConnect.
Open InfoConnect and then open the mySession.rd3x and mySession.rdox sessions and select the IBM mySession.rd3x session.
Run the project and verify that the text from the IBM session screen is written to the Console.
Close your project application.
Select the Open Systems mySession.rdox session
Run the project again and verify that the text from the Open Systems session screen is written to the Console.

Getting a View Using Title Text

This sample gets both the Views and Controls for two sessions by referencing the title text of the Views.

In InfoConnect, create an IBM session and an Open Systems session and save these sessions as mySession.rd3x and mySession.rdox in the default folder. (...\myDocuments\Micro Focus\InfoConnect.)
In Visual Studio, create a new Console Application project and add references for the following InfoConnect assemblies. (Depending on your version of Visual Studio, these can be found either on the .NET tab or under Assemblies | Extensions.)
