    Detailed Description

    CDbStrings encapsulates functionality used for transferring an array of strings from DBMS server to the DBMS client. The maximal length of each element of the array is KDbMaxStrLen characters. The typical usage pattern of CDbStrings class is: 
    CDbStrings* strings = <a call of an exported DBMS method>;
TInt cnt = strings.Count();
for(TInt i=0;i<cnt;++i)
	{
	const TDesC& str = (*strings)[i];
	<do something with "str" variable>;
	}
delete strings;
