How to programmatically use Word's "Compare and Merge Documents..." functionality from C#?

Question

Is it possible to call Word 2003's Tools > Compare and Merge Documents..." function from C# and to get feedback whether any differences were found or not?

What I have found so far

It is possible to call the functionality like this. But I don't k开发者_开发问答now how to get feedback whether the were any differences found.

    private void CompareAndMergeWithFileB(string fullFilePath)
    {
        string FileName = fullFilePath;
        object MergeTarget = WdMergeTarget.wdMergeTargetSelected;
        object DetectFormatChanges = false;
        object UseFormattingFrom = WdUseFormattingFrom.wdFormattingFromPrompt;
        object AddToRecentFiles = true;

        word.ActiveDocument.Merge(FileName, MergeTarget, DetectFormatChanges, UseFormattingFrom, AddToRecentFiles);
    }

Absolutely. Once the merge is complete, work with the Revisions collection to extract details about any changes.
