Reusing a DataWindow object

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
