Scripting - Classification Using Bar Codes

Issue

Classification Using Bar Codes

Solution

If you want to use a bar code for classification:

1. Create a bar code locator on project level. (Locators on project level will be executed before any classification takes place.)
2. Create a field on project level (e.g., named "Barcode").
3. Connect the field with the locator.
4. Add the following code to the project script:

   Private Sub Document_BeforeClassifyXDoc(pXDoc As CASCADELib.CscXDocument, _
                                           bSkip As Boolean)
       Dim BarcodeText As String
       BarcodeText = pXDoc.Fields.ItemByName("Barcode").Text
       If BarcodeText = "12345" Then
           pXDoc.Reclassify("Form12345")
       ElseIf BarcodeText = "67890" Then
           pXDoc.Reclassify("Form67890")
       Else
           ' continue with normal classification
       End If
   End Sub

The Reclassify method can be called several times during processing in order to classify a Document to a different class and perform the extraction again. Note that to avoid endless loops, the use of the Reclassify method is limited; it can be called once per classification step and up to 100 times per extraction step.

In addition, the event has a new optional parameter, Confidence, that is used to set the confidence value for the Document after reclassification.
