Exception when constructing a Document


I am getting the following exception on a clients machine when I try to construct a Document class with a word document. I am using Aspose.Words

The word document appears to be ok.

Any ideas would be appreciated.



Thanks for your request. Please provide me the code to reproduce this problem. Also try to use the latest version of Aspose.Words. You can get the latest version here:

Best regards.

Hi I am Getting the error

Unable to cast COM object of type 'Microsoft.Office.Interop.Word.DocumentClass' to class type 'Aspose.Words.Document'. Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface.

Word.Document document = (Word.Document)docEdit.ActiveDocument;

Aspose.Words.Document doc = (Aspose.Words.Document)document;

where docEditor is the ocx control

Can you tell me how do i convert from word ocx control to Aspose.Words.Document

with regards

Hi<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Thanks for your inquiry. I think that you should read document from your control into the stream and the create Aspose.Words.Document from that stream.

Best regards.
