Excel Application return “File Save” instead of “Save As” dialog

Question

Why auto dialog = _excelApp.get_FileDialog(Office.MsoFileDialogType.msoFileDialogSaveAs); returns "File Save" dialog?

How to get "Save As" dialog?

Answer 1

There is no "Save as" dialog in Excel at all. I can see only a "File save" dialog.

Even using the UI in any possible situation I can only see only one "File save" dialog that is used to ask for a name the first time, or ask for a new name.

So using msoFileDialogSaveAs is all you have.

Answer 2

It seems to be a bug in microsoft's dll. I used another interface which works fine:

Excel.Dialog dialog = _excelApp.Dialogs[Excel.XlBuiltInDialog.xlDialogSaveAs];
dialog.Show();
