Use Connection Macros

In This Topic

Using macros to establish host connections can be quite useful, particularly if you connect to multiple hosts, or use different connection settings.

If you use OpenSystems hosts, you may also want to use macros to configure your connection settings, especially if you use automation to create Reflection session documents. (If you save the correct host connection information in the session document that contains your macros, you don't need to change connection settings programmatically.)

When using macros to configure settings, use these best practices:

Identify and change the connection type using the OpenSystems Terminal object's ConnectionType property. To use the best network connection possible, specify a connection type of BestNetwork.
Use a ConnectionSettings object (for example, ConnectionSettingsTelnet) to configure the individual settings for the connection type.
Set only those properties you need to change. Properties you don't change are set to default values.

Note: If you assign values that are invalid to the properties of the ConnectionSettings object, or you try to set a property that can't be changed when the connection is open, errors can result. Include an error-handling routine in your macro to trap and deal with these errors (for example, by displaying a message box). You can retrieve the error text using the ConnectionErrorMessage property.

This sample retrieves the type of Open Systems connection that is used and displays it in a message box.

This sample applies only to Open Systems terminals.

To run this sample

In an Open Systems session, open the Visual Basic Editor and then enter the sample code in the ThisTerminal code window.

    MsgBox (msg)
End Sub

Disconnect the session and then reconnect to display the connection type.
