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 PDF Xpress component in PDF_EvaluationTimeOut mode under the Visual Basic 6 IDE, the component will still display the evaluation dialog.  However, setting the EvaluationMode property to PDF_EvaluationTimeOut will allow your Visual Basic 6 compiled executable to properly timeout after 5 minutes of execution and not display the evaluation dialog.
