EvaluationMode Property

Description

Gets and sets how the control will behave when in evaluation (non-licensed) mode.

Property Type

Read-write property

Syntax

Visual Basic
Public Property EvaluationMode As TP_EvaluationMode

Return Type

A TP_EvaluationMode enumeration value which determines how the control behaves in evaluation mode.

Remarks

The default value is TP_EvaluationModeAutomatic.

In order to test the component in an application running as a service or other environments where the component does not have permissions to create a window, the application logic needs to set the EvaluationMode to Timeout. In this mode, the component does not attempt to create the Evaluation Mode dialog window, but will timeout after 5 minutes of operation and cease to operate.

When running your project with the TwainPRO component in TP_EvaluationModeTimeout mode under the Visual Basic 6 IDE, the component will still display the evaluation dialog. However, setting the EvaluationMode property to TP_EvaluationModeTimeout will allow your Visual Basic 6 compiled executable to properly timeout after 5 minutes of execution and not display the evaluation dialog.

To run in regular (not evaluation) mode, purchase and register a license.
