COM Interoperability: Recognizing Pages
Take the following steps to start a project and to add some code that demonstrates how to draw pages and zones:
  1. Start with the program you created in COM Interoperability Working With Pages
  2. Drag and drop two command buttons in Form1. Leave all the buttons names as the default "Command6, Command7 ...", then change the following properties of Command6:
    PropertyValue
    Caption Recognize
  3. Change the following properties of Command7:
    PropertyValue
    CaptionGets Status
  4. Add the following code for the Command6 control’s click procedure: 
    
Private Sub Command6_Click()
   ' Set the english as the language for the checking subsystem that will be used for spell checking
   documentEngine.SpellLanguageId = RasterDocumentLanguage_English
   documentEngine.EnableSubsystem = True
   documentEngine.EnableCorrection = True

   ' Specifies the name of the file that will be used in the recognition.
   documentEngine.RecognitionDataFileName = "c:\testrdf.rdf"

   ' Recognize the first page of the RasterDocument object.
   documentEngine.Recognize 0, 1
   MsgBox "The engine finished recognizing the specified pages successfully"
End Sub
  5. Add the following code for the Command7 control’s click procedure: 
    
Private Sub Command7_Click()
   ' Print some information about the recognition status
   Dim status As RasterDocumentRecognitionStatistic
   Set status = documentEngine.RecognitionStatistic
   Dim msg As String

   msg = "Recognition Time = " + CStr(status.RecognizedTime) + Chr(13) + _
         "Total Recognized Characters = " + CStr(status.RecognizedCharacterCount) + Chr(13) + _
         "Total Recognized Words = " + CStr(status.RecognizedWordCount) + Chr(13) + _
         "Total Rejected Characters = " + CStr(status.RejectCharacterCount) + Chr(13) + _
         "Total Rejected Words = " + CStr(status.RejectWordCount)
   MsgBox msg
End Sub
  6. Build and Run the project to test it.
  7. Save this project to be used for testing other code samples.
