Reuse V/S Extra Component

[abhijitkolhatkar]

Hi All,
Following is the scenario.
I am having a Sequential Section in my report which has 11 Report Sections.
Each Report Section reads SAME File.
Following are the two approaches to do that:
1. I thought it will be better to read the file once and store it in the buffer and use the buffered row again and again..
2. Straight Forward Approach: I can read the file again and again on all 11 report sections.
Following is a way reusability was implemented
In the 2nd Approach I can REUSE the DataStream component:
Following is how I can do that.

Step I:
Add one data stream component to one report section.

Step II:
In "Properties" for All ReportSections (AcReportSection), we can find "Slots" property group and there is a property associated for "DataStream".
Put the value for this property as
<ReportClassName>::<DataStreamName> (ReportClassName is name of ur ReportComponent, ur GRAND PARENT REPORT with AcReport class)

Now, My questions are:
1. Is it actually REUSABILITY?
2. I can implement this for HEADER FRAMES and other controls also whihc are common across multiple sections/sub-reports in same Main Report.
3. Does this kind of reusability has any advantages related to Performance etc?If yes why? If no why not?

Thanks in Advance!
