Using:
VC++ 4.0 std. ed.
 project: mdi with file support
  with: ODBC database -
      created with SQL Central (Sybase product)

my experience level: ex-Clipper programmer - new to VC++

I am developing this program in cooperation with the end user so there will be many changes over the weeks to the database and program. In fact, I have created the database with just 3 tables, there will probably be 6 in all. Some of the tables have no columns (fields) yet.

I recently added some columns, but the program does not "see" this new structure. Do I have to re-generate the whole project? or re-register the database with Win95? in other words start from scratch each time I make a change to the .db?

Thanks, Pete

You must use ClassWizard for your database class. Thre is "Update Columns" button in "Member Variables" tab. Press it and I hope it solve your problem.

Being new to VC++ I will now have to go find this ClassWizard. If I don't find it, I'll come back to you with my next obvious question.
Thanks
