My problem seems to be simple.  I need to open up an odbc driver linked to an excel spreadsheet in Delphi and then read some data from it.  Seems simple, but I can't seem to find the best way.  

First of all I set up a odbc datasource for the spreadsheet.

I then setup a tdatabase component and connected it without a hitch.  I then drop a ttable on the form and reference the tdatabase but when I try to select the tablename the system crashes.  

Using ADO I dropped a tadoconnection on the form, setup the connection string, tested the connection and set the connected to true, no problems.  I then drop a tadotable and referrence the tadoconnection.  There is nothing in the drop down for tablename and when I try to set active = true, it tells me the tablename is missing.

Help!

It's a little bit long to explain how to connect to excel using ado
Here's a tutorial to start in this way http://delphi.about.com/od/database/l/aa090903a.htm

you may have to setup in excel a region of your spreadsheet that will be the table. that is useful when you have complex speadsheet and want only a specific area of it to be accessible as a table.
I think that is done by selecting the region (with the first line being the column headers), and setting a name to that region. In ribbons GUI, it is in the 'Formula' ribbon, 'Name Manager' section, then 'Define a name'
I know Excel should allow access to each spreadsheet as a whole table, without setting an area name. But maybe there is now security functionality that prevent it to work.
I'll try to test it with an environment as close as possible as yours : what is your Delphi version and what is your Office version ?

Here is a full sample project, with comments inside the app and the excel file.
Accessing Excel from ADO, while convenient with simple needs, is definitely NO DB alternative, when adding data and joints are required ADOExcel.zip

Wish I could give an A++++.  This was a great solution and the example made it easy to work through!  I know it's not always possible to go to this length to explain something but in this case with all the many variables, it was a tremendous help. Thank you!!!!
