c# Word COMException (0x800A11FD) when adding a new field to document RRS feed

  • Question

  • I want to add a new field to the Fields list in document. I am calling Doc.Unprotect("secret") to be able to add the new field because the selected fieldText is in a protected document. When the Doc.Fields.Add method is called I get the undefined COMException below.

    Does anybody know why this is happening?

    Doc.Unprotect("secret");

    Doc.SetDocProperty(fieldKey, fieldText);

    W.Field field = Doc.Fields.Add(app.Selection.Range, W.WdFieldType.wdFieldDocProperty, fieldKey, true);

    Exception:

    System.Runtime.InteropServices.COMException (0x800A11FD): Dieser Befehl ist nicht verfügbar.(=Command not available)
       bei Microsoft.Office.Interop.Word.Fields.Add(Range Range, Object& Type, Object& Text, Object& PreserveFormatting)

  • Hello,

    This is not a VB.NET issue so for better visibility I'm moving your question to the Word for Developers forum.

  • What kind of protection are you using, and what is being selected before you run your code?

    For example, if you are protecting for forms and the selection is in a plain text content control, you will see that kind of error because you can't insert a field into that type of control. (You would probaby see it if the control was locked for editing etc. too, but I haven't checked)
