Hi ,

I am trying to retrieve the text for an scanned image by adding the refernce "MDIVWCTL.DLL" to my Vb.Net project.(2008 Standard Edition)

While executing the code i get error at mt Create statement:- I get the 'System.Runtime.InteropServices.COMException'

VB

Dim ModiDoc As New MODI.Document
Dim sPath As String : sPath = "C:\SingleImage.tiff"

ModiDoc.Create(sPath)
ModiDoc.OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, False, False)
MsgBox(ModiDoc.Images.Count)

Note :- the Microsoft Image scanning 2007 with OCR is already installed in my system.

Will aprreciate if can get a quick response to my issue :)

"COMException" is not exact - please give more info (e.g. COM error code, COM error message).
By the way, do you have write access to C:\? - That's not a good location for files.

The issue got resolved. Actually i had written wrong extension ".tiff" instead of ".tif" :)
