Serialization of the Data
The Data object can be exported into/imported from a file. To achieve this, there are special Importer and Exporter
objects. Example:
Sub ImportData(App As Application, filename As String)
Dim ie As Importer
Set ie = App.CreateObject("dataset::DataImporter")
ie.Import filename, App.Project.dataset
Set ie = Nothing
End Sub
Sub ExportData(App As Application, filename As String)
Dim de As Exporter
Set de = App.CreateObject("dataset::DataExporter")
de.ExportData filename, App.Project.dataset
Set de = Nothing
End Sub
As you can see from the example, the following is done:
- Define a variable of type Importer, or Exporter respectively
- Use the App.CreateObject method with the parameter “dataset::DataImporter”, or
“dataset::DataExporter ” respectively (these are fixed keywords), and assign it to the variable.
- Call its method Import , or Export respectively, which takes a file name and the dataset object as parameter.
Note that the Export method will not erase the data from the dataset; if you want this to be done, use the Clear
method of the Data object. Likewise, the Import will add data to any existing data in the dataset, set you might
want to clear the existing data beforehand.
The format of the file is an internal XML format. It is not intended to be interpreted be any other program.
