I'm developing an application over visual basic, and I don't know how write values on table elements. The example in CD only show how read items but don't show how write items, principally table items, can anybody help me ? Thanks

Hi,

We looked at the strategy, VB app, and database you sent to support@opto22.com.  The VB code was correct.  The problem was found to be with the tags in your Access database.  One database entry was trying to read 20 elements from a strategy table that only has 10 elements.  Also, many of the database entries had extra space characters at the end of the tags, and this caused problems.  I E-mailed the updated database to you with these problems fixed, and it works now.  We are also updating the OptoOPCServer to prevent the extra spaces from causing problems in the future.
