    How to use MODI(MS Office Document Interface) in VB6?

    I already reference the MODI v12 library and use the following sample code. But when I run the project, it shows me an error at "miDoc.Images(0).OCR" with error message: Object hasn't been initialised and can't be used yet.

    Actually I'm doing a simple project that input a tif file and then perform the OCR process and output the tif content to a text.

    For example the tif file got "ABCDEFGHIJ" then I want to use the MODI OCR to output the ABCDEFGHIJ from the TIF picture.

    Anyone please help me here...

    Code:
    Sub TestWords()
      
      Dim miDoc As MODI.Document
      Dim miWord As MODI.Word
      Dim strWordInfo As String
      
      ' Load an existing TIFF file.
      Set miDoc = New MODI.Document
      miDoc.Create "C:\document1.tif"
      
      ' Perform OCR.
      miDoc.Images(0).OCR
      
      ' Retrieve and display word information.
      Set miWord = miDoc.Images(0).Layout.Words(2)
      strWordInfo = _
        "Id: " & miWord.Id & vbCrLf & _
        "Line Id: " & miWord.LineId & vbCrLf & _
        "Region Id: " & miWord.RegionId & vbCrLf & _
        "Font Id: " & miWord.FontId & vbCrLf & _
        "Recognition confidence: " & _
        miWord.RecognitionConfidence & vbCrLf & _
        "Text: " & miWord.Text
      MsgBox strWordInfo, vbInformation + vbOKOnly, _
        "Word Information"
      
      Set miWord = Nothing
      Set miDoc = Nothing
    
    End Sub

    I pasted your code into a one-button form and it worked fine. I would try another TIF file - maybe the one you're using isn't formatted correctly.

    The files that I use are simply scanned on a flatbed scanner straight to a TIF file. MODI has had no problems with those.
