Defining the Component's InterfaceThe method's return cannot be an array. If this functionality is needed, the data shouldbe returned in a parameter.Specifying the ParametersOn the Change Parameters dialog, the Service Widgets column displays the names ofthe fields on the service component. Select the widget names and use the arrow buttonsto add parameters to the grid. If the widgets are arrays, the array specification isselected for the parameter.To the right, the grid displays the list of parameters for the method. Each row in thegrid corresponds to a parameter. The order of the parameters is important; it is theorder clients will use when calling the component.Choosing Modify (or double clicking on a parameter name) opens the ChangeParameter window, which contains four fields:! Name—The parameter's name.! Type—String, Int, Bool, Double, or Object.! An Array check box.! Kind—In, Out, or In/Out.3-6 Building COM Components
Defining the Component's InterfaceChoose the desired options for each parameter.Implementing the MethodOn the method's Change Parameters dialog, choosing Template generates a JPLprocedure for the method and its parameters in the Windows clipboard. This generatedJPL template can then be pasted into the screen-level JPL procedures or a file.In the COM samples, the Template option generated the following JPL for theGetCustomer method:proc GetCustomer{receive_args (CompanyName)return_args (CompanyName, CustomerID, Phone)}Defining PropertiesThe Properties section in the Component Interface window displays a grid that showsthe properties supported by the component. Often, properties are defined to containinformation about the application state.COM/MTS Guide 3-7
