How to delete/remove the hidden text in word document

Question

Hi,

I am inserting a hidden field to Word Document using below C# code:

Word.Range wmRange = null;
docId = "Date: X ID:Y  ProductName: Z"
object offset = (object)_wordDoc.Content.Start;
wmRange = _wordDoc.Range(ref offset, ref offset);
wmRange.InsertBefore(docId + "\n");
wmRange.Font.Hidden = -1;
wmRange.Font.Size = 6.0f;

Now i want to delete the inserted hidden text. Put let me know how i can do this.

Regards,

Hi Chetan

Usually, we'd probably work with the Range.Find object, setting Find.Font.Hidden to true and Find.Replacement.Text = "" (empty string).

You can test this in the UI and, if it works for you, record a VBA macro to get the basic syntax to work from.

Ctrl+H will display the Replace dialog box. Click on the "More" button at the bottom left. Click on Format, choose Font, activate "Hidden", OK. Now click Replaced All.

Hi Cindy,

I tried below 2 code but it did not work :(  ,

1. Word.Range wmRange = null;
    object offset = (object)_wordDoc.Content.Start;
     wmRange = _wordDoc.Range(ref offset, ref offset);
     wmRange.Find.Font.Hidden = 1;
     wmRange.Find.Replacement.Text = "";

2.  Word.Selection sel = _wordApp.Selection;
            sel.Find.ClearFormatting();
            sel.Find.Font.Hidden = 1;
            sel.Find.Replacement.ClearFormatting();
            sel.Find.Text="";
            sel.Find.Replacement.Text = "";
            sel.Find.Forward = true;
            sel.Find.Wrap = Microsoft.Office.Interop.Word.WdFindWrap.wdFindContinue;
            sel.Find.Format = true;
            sel.Find.MatchCase = false;
            sel.Find.MatchWholeWord = false;
            sel.Find.MatchWildcards = false;
            sel.Find.MatchSoundsLike = false;
            sel.Find.MatchAllWordForms = false;

Please let me know where i am going wrong.Thanks in advance.

Hi Chetan

It always helps if you tell us HOW something doesn't work...

However, in Word the numerical equivalent of True is usually -1, not 1. In addition, you must tell Find to perform the Find/Replace action: wmRange.Find.Execute(//parameters here);

If you change these things do you get a better result?

Hi Cindy,

The below code worked fine for me, :)

object missing = System.Reflection.Missing.Value;
            object replaceAll = Word.WdReplace.wdReplaceAll;

            _wordApp.Selection.Find.ClearFormatting();
            _wordApp.Selection.Find.Font.Hidden = 1;

            _wordApp.Selection.Find.Replacement.ClearFormatting();
            _wordApp.Selection.Find.Text = "";
            _wordApp.Selection.Find.Replacement.Text = "";
            _wordApp.Selection.Find.Forward = true;
            _wordApp.Selection.Find.Wrap = Microsoft.Office.Interop.Word.WdFindWrap.wdFindContinue;
            _wordApp.Selection.Find.Format = true;
            _wordApp.Selection.Find.MatchCase = false;
            _wordApp.Selection.Find.MatchWholeWord = false;
            _wordApp.Selection.Find.MatchWildcards = false;
            _wordApp.Selection.Find.MatchSoundsLike = false;
            _wordApp.Selection.Find.MatchAllWordForms = false;

            _wordApp.Selection.Find.Execute(
                ref missing, ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref missing, ref missing,
                ref replaceAll, ref missing, ref missing, ref missing, ref missing);

Thanks alot.
