Declaring type variables or composite data types
by DevX Pro
I need to be able to print results of a query to an Excel spreadsheet rather than to a report. I am using the Crystal Reports product included with Oracle Power Objects. However, it clearly states that the Crystal Reports OCX does not work with Windows 3.1, so I am using the Crystal Reports DLLs. One of the functions I need to use requires the use of a composite data type. In Visual Basic this would look like: Public Type variable-name SubVariable_Name1 as DataType SubVariable_Name2 as DataType ... End Type Unfortunately this declaration does not work for OPO. And I can find no similar method anywhere. How can I declare a composite user-defined data type in Oracle Power Objects for use in these DLL functions?
Can Crystal Reports output to MS Word?
by DevX Pro
The Crystal Reports help file contains "Pro-only Topics." Can I use these Pro features with the Crystal Reports engine I recieved with OPO? If so, where can I find an example of outputting a Word document? I am developing a work flow system for a gov. agency and would love to output and save to an Oracle database a Word Doc.

How do I achieve consistent data retrieval performance?
by DevX Pro
My application is working with a fairly large database. Although users will never be allowed to request all of the data, different selection conditions may return wildly varying amounts of data. I'm worried that the performance of the data retrieval may be inconsistent, based on how much data is retrieved from a particular user request.

Inserting rows without retrieving data
by DevX Pro
I have a very large table that contains thousands of rows. I want to let a user insert new rows into it on a particular form without having to query the table. How can I create a recordset that is bound to a table and session so that I can quickly insert the row and then close the recordset?
