I have read numerous articles and postings on various approaches to
exporting
a DataSet to excel while avoiding the use of automation. I found the
most performant approach to be assigning a string array of data to a
range in excel (similar to a copyfromrecords et). However, with this
approach, the datatype is lost and all numeric columns in excel appear
as string.
In order to overcome this, I tried calling TextToColumns on each
column. This works except oddly some string values are getting broken
up into multiple columns.
I have also tried MS code to create a RecordSet from a DataSet and
perform a CopyFromRecords et. The recordset gets created, however the
CopyFromRecords et does not work.
Has anyone had any success with either of these approach...or have
some other approach to export DataSet contents to excel without heavy
use of automation and at the same time maintaining the datatype of the
column?
Thanks in advance.

Thanks for your post. I see that you are querying data OUT of Excel
into a DataSet object using ADO.NET, but can the reverse be
accomplished in this manner...can data from a DataSet be pushed INTO
an Excel worksheet?

You could loop through the rows of each table in your dataset seperating
each value with a tab and then each row will be ended with a vbcrlf. Then
save this output to a file with a .xls. You should then be able to open
this up using excel since its in a format that excel can understand.
