[AccessD] DoCmd.TransferSpreadsheet tip

[Stuart McLachlan]

Worked it out.  Using the Range parameter to define the spreadsheet name applies the 
standard Range name conventions. There is no getting around that.

i.e. 
It  must start with a letter or an underscore. If not it will get a preceeding underscore.

It can be any single alpha character except R or C

It cannot be interpretable as a cell value. Column names range from A to XFD so any one 
to three letters in that range followed by any number up to 1048576 will get a 
leading underscore.

It can't contain any non alphanumeric character other that period,question mark, underscore 
and backslash .All invalid characters are replaced by underscores.

If it conflict with any existing name, the existing sheet will be replaced.
