Word field is invisible - current channel

ApsSanj 6

I am working on an add-in for Microsoft Word, VSTO application, we are doing content tagging with Word.Fields, and it was working fine for several years. Suddenly users reported failures in inserting tags. And all the users who reported the issue are using Office 2412 build or latest on the current channel. I am using 2411 and I am on Monthly enterprise channel, issue is not recreating for me.

Below is an image of the field codes of the correct and with issue tag issue

In the tag with issue, it contains all the field codes and values, the missing part (compared to the other tag) is actually hidden. If you look carefully in the highlighted place, I have selected the missing Word.field in there using field.Select using vba. I can read it's content through code.

Also users having error pop-up when inserting the field codes at the end of the document. We have a logic handle for that instance in our original code, we add a empty paragraph at the end of the document using range.InsertParagraphAfter. seems that is not working now. I tried giving the user a test build with objWordRange.InsertAfter("\r"); instead of all instances of range.InsertparagraphAfter and it seems to fix that issue as user now don't have that error (can't 100% sure, anyway error is now not in their logs). But the objWordRange.InsertAfter("\r");didn't fix the field code invisible issue.

We are using range.InsertparagraphAfter and range.Collapse(Word.WdCollapseDirection.wdCollapseEnd);, range.Collapse(Word.WdCollapseDirection.wdCollapseStart); several times within this tag insertion. But when inserting the invisible tag, code seems not functioning as implemented, as it is selecting in a weird location as seen in that screenshot. Any idea or hints on what we need to make the code working back soon? as it is really urgent. Note : Out IT team is working on getting me current channel of Word. Still it is in progress.

@Paul Edstein Sorry about cross posting. I read the article. Thanks about it. Main reason I had to did it was when I post this question, I was unable to upload images. Now I can. I modified the issue and deleted stackoverflow issue.

I have identified the cause for this issue.

When inserting Word.Fields using range.Fields.Add() with Word version 2412 or latest (there got 6 sub versions of 2412 in this release notes, but not all version has this issue, guess this change is done in a latest release), we are getting this <w:r> <w:fldChar w:fldCharType="separate" /> </w:r> xml part in the document.xml. This didn't occur with version 2411 or earlier.

This change has affected the field.Result() returning range value. That's why I am experiencing the issue. It is returning a value in between as I noticed.

Word.Range wordRange = field.Result(); Word.Range range = wordRange.Duplicate; range.Collapse(WdCollapseDirection.wdCollapseStart);

Get the range this way and when use the below code to check the position of the range, it returns the paragraph position as middle. Earlier it returned as 'end'.

public wdParagraphPosition GetParagraphPosition(Word.Range wordRange) { /* Returns an enumeration to indicate if the start of the passed range is at the beginning, middle or end of a paragraph, or if it resides in an empty paragraph. */ Word.Paragraph paragraph; paragraph = wordRange.Paragraphs.First; if (paragraph.Range.Text.Length < 2) { return wdParagraphPosition.Empty; } else if (wordRange.Start == paragraph.Range.Start) { return wdParagraphPosition.Start; } else if (wordRange.Start + 1 == paragraph.Range.End) { return wdParagraphPosition.End; } else { return wdParagraphPosition.Middle; } }

So when I try to insert an empty paragraph using range.InsertParagraphAfter(), it is not working. Which cause this issue.

Any idea on how to get the field's range in correct way?
