You can reuse a DataWindow object by retrieving its syntax from the library it is stored in, then using the syntax to create a DataWindow object dynamically in a DataWindow control.
Here is a typical way to accomplish this in an application. Use:
-
The LibraryDirectory function to obtain a list of DataWindow objects and other library entries in the current library
-
A DropDownListBox to list the DataWindow objects in the library and then allow the user to select a DataWindow from the list
-
The LibraryExport function to export the selected DataWindow object syntax into a string variable
-
The Create method to use the DataWindow syntax to create the DataWindow object in the specified DataWindow control
-
The Describe method to get the current DataWindow object syntax, for example:
string dwSyntax dwSyntax = dw_1.Describe("datawindow.syntax") -
The Modify method to allow the user to modify the DataWindow object
-
The LibraryImport function to save the user-modified DataWindow object in a library
