SaveAs Method - Overwriting existing file

[Erl Egestad]

If I invoke the SaveAs method on a fully trusted form and via script save the
with a name of an existing InfoPath XML file (in essence I want to overwrite
an "old" version of the file's XML data), will InfoPath be prompted with the
standard Office - "Are you sure want to overwrite an existing file" message
box?

I want to prevent the user from having ANY control over the Save process
entirely?

Thanks!

You can use the FileSystemObject to check whether the file exists and
delete it before saving:
if (fso.FileExists(filespec))
fso.DelteFile(filespec);

Or if you want to cover all the bases and do it right, it might look
something like this

var f;
var attr = 0;

try
{
if (fso.FileExists(filespec))
{
f = fso.GetFile(filespec);
attr = f.attributes;
f.Move( <some temp backup file> );
}
XDocument.SaveAs(filespec);
fso.DeleteFile( <temp backup file> );
}
catch (ex)
{
if (fso.FileExists( <backup filename> )
{
fso.MoveFile( <backup filename>, filespec);
f.GetFile(filespec);
f.attributes = attr;
}
}
