ASP Form Maker

--------------------------------------------------------------------------------

Description : Creates an HTML form given an ADO recordset. Uses different controls (textbox, checkbox, textarea) for different datatypes. Determines maxlength property based on datatype. Keeps some useful info in hidden fields.

.moreTblTags
.moreCaptionTags
.moreCellTags
.moreRowTags
Other:
.uniqueField - defaults To 0. change If needed.
.print(rs) - prints one record from the recordset.
'
' Returns:uses response.write to output
' nicely formatted HTML (with tabs and lin
' efeeds).
'
' Assumes:Tested on all JET/ADO datatype
' s. Extensive SQL server testing coming s
' oon. Should work though.
There are some hidden fields With no value that you can update With JS If you like (example 'selected field').
You should use cascading style sheets To format the form.
NS & IE Event management In Next version.
'
' Side Effects:Writes query string to a
' hidden field if you don't use a view.
Does Not correctly determine maxlength For numeric types (except short Int, And Byte).
'

<%
'TO DO:
' cross-browser event handling (caption
' onclick, field on change)
'shouldn't use HTML tags for formatting,
' use CSS
'verify with all SQL Server types.
'add 'goto hyperlink' and 'sendmail' ico
' ns if field contains (only) a url
'fix maxlength. shows number of bits for
' numbers.
' end to do
