Office.Interop.Word - app.DisplayAlerts = WdAlertLevel.wdAlertsNone; Not Disabling Alerts

Question

I'm trying to disable read-only alerts when opening word files in C#. I initially tried app.DisplayAlerts = false. This did not work and I believe it's because I have a newer version of word. Now, using word.DisplayAlerts = WdAlertLevel.wdAlertsNone does not disable the popups either. I'm not sure why, as I've seen several StackOverflow posts indicating that it should. Here's my code (part of a method to convert doc to docx):

Application app = new Application();

app.DisplayAlerts = WdAlertLevel.wdAlertsNone;

var sourceFile = new FileInfo(path);

var document = app.Documents.Open(sourceFile.FullName);

string newFileName = sourceFile.FullName.Replace(".doc", ".docx");
document.SaveAs2(newFileName, WdSaveFormat.wdFormatXMLDocument,
    CompatibilityMode: WdCompatibilityMode.wdWord2010);
app.ActiveDocument.Close();
GC.Collect();
GC.WaitForPendingFinalizers();
app.Quit();
app = null;
GC.Collect();

Any suggestions?

Answer 1

Have you considered opening the document readonly? That prevents the readonly alert. You have to pass the readonly:=true to the document.open method.
