// Summary:
// Encapsulates a collection of CXTPReportRow pointers that represent

// Remarks:
// Use this class to programmatically manage a collection of

// Report Control. This class is commonly used to add or remove rows
// from the collection.
//
// Typical work flow is using Add and Remove methods for changing
// contents of the selection and using Contains method for checking
// a specific row for its presence in the selection.
// Example:
// The following example demonstrates how to programmatically use
// the CXTPReportSelectedRows class to select rows in the Report control.
// <code>
// CXTPReportSelectedRows* pSelRows = pReportControl->GetSelectedRows();
// pSelRows->Add(pRow1);
// pSelRows->Add(pRow2);
// ASSERT(TRUE == pSelRows->Contains(pRow1));
