Producing Word document with windows form, doesn't work for all PCs: System.Runtime.InteropServices.COMException (0x800A16CA)

Question

Hello,

I developed a windows form app to produce Word reports. At the beginning it worked fine on all the PCs producing well done documents, after I added the following chunk of code it stopped to produce the reports when executed on some PCs.

                    object end = 0;
                    object start = 0;
                    string title = Regex.Replace(tab.Cell(1, 1).Range.Text, pattern, dati[7]);
                    Range rng = doc.Range(ref start, ref end);
                    rng.Text = title;
                    Object styleHeading2 = "Heading 2";
                    rng.set_Style(ref styleHeading2);
                    rng.Paragraphs.OutlineLevel = Word.WdOutlineLevel.wdOutlineLevel2;
                    rng.Paragraphs.SpaceAfter = 10;

I found that, on the PCs where it doesn' work, the code throws the following exception:
System.Runtime.InteropServices.COMException (0x800A16CA): the item with the specified name does not exist.
in Microsoft.office.Interop.Word.Range.set_style(Object& prop)

Do you have any idea to solve it??

thank you

Answer 1

The problem was about Word's language. On my pc Word is in english, but my colleagues have native language Word thus they don't understand the command:

Object styleHeading2 = "Heading 2";

The solution is to set style using Word.WdBuiltinStyle enumeration, in this case:

Object styleHeading2 = WdBuiltinStyle.wdStyleHeading2;
