Use this dialog to specify the needed parameters for the object properties that accept parameters and thus evaluate the property value in the Object Browser panel. To call the dialog, click the 
button that is displayed next to the parameterized property in the Properties page of the Object Browser.
In the dialog, enter the property parameters. Although, TestComplete treats all property parameters as OLE Variant values, some properties may require that their parameters have a definite type. For these parameters TestComplete lets you specify the type of the entered value (for instance, string or integer).
Once you have finished with the parameters, click OK and if the entered values are valid, the Object Browser will display the resulting property value. To close the dialog without saving your changes, click Cancel.
