For example, suppose you want to make changes to an existing contact or calendar entry, and export the same to an external file store. To do so, again create the appropriate parser objects. That is, <xref href="GUID-F4BEE3F4-F268-345D-B727-2C1D5E25F3F7.dita"><apiname>CParserVCard</apiname></xref> and <xref href="GUID-6BEFF6A7-FBD8-306D-98A4-8711E788C702.dita"><apiname>CParserVCal</apiname></xref> objects to export vCards and/or vCalendars. For more information on importing vCard and vCalendar, refer to <xref href="GUID-2A39CCBD-CADB-56B7-872A-1EC617AC7D93.dita">How to Import Contact and Calendar Data</xref>. </p> <p>Let us assume that, you want to add a new property to the vCard called <i>EMAIL</i> with the parameters <i>ENCODING</i> and <i>CHARSET</i>, and the property value of <i>foo@bar.org</i>. To do so, you need to create objects of <xref href="GUID-895C3D03-FE10-329C-9437-2948686509C5.dita"><apiname>CParserProperty</apiname></xref>, an array of <xref href="GUID-4A02E5BD-39D3-34AD-B70B-8177144FF12C.dita"><apiname>CParserParam</apiname></xref> to hold parameter information, and <xref href="GUID-76E6CCFA-5BAC-34F1-A5B2-FB505A68E784.dita"><apiname>CParserPropertyValue</apiname></xref> to hold the property values. </p> <codeblock id="GUID-B97F4C10-25A1-504E-A072-5E65EA5EEB73" xml:space="preserve">// String literals representing the property and its value.

_LIT(KParam2,"CHARSET");

_LIT(KValue2,"US-ASCII");

CParserPropertyValue* value=CParserPropertyValueHBufC::NewL(KEmail); // The property value.

// Array to hold parameters of EMAIL property.

CArrayPtr<CParserParam>* arrayOfParams = new(ELeave)CArrayPtrFlat<CParserParam>(2);

// Parameters with their corresponding values are added to the array.

CParserParam* parserParam1=CParserParam::NewL(KParam1,KValue1);

arrayOfParams->AppendL(parserParam1);

CParserParam* parserParam2=CParserParam::NewL(KParam2,KValue2);

arrayOfParams->AppendL(parserParam2);

// Associate the property params and property value with the EMAIL property

CParserProperty* property=CParserProperty::NewL(*value,KPName,arrayOfParams);

// Finally add the EMAIL property to the vCard using the parser object.

vCardParser->AddPropertyL(property);

// Set the character set as ASCII (7-bit) for transformation.

vCardParser-&gt;SetDefaultCharSet(Versit::EUSAsciiCharSet);</codeblock> <p> <i>Note that you should include proper error checks in the above given code before using it for production.</i>  </p> <p>Once you have added the EMAIL property, you can externalize (export) the vCard. This time you have to open the file in write mode to externalize the vCard data. </p> <codeblock id="GUID-639AAC10-2332-5408-86F8-24045A3F0094" xml:space="preserve">TInt err = file.Replace(iFsSession, KVCardFileJIS, EFileWrite) // Replace the file with modified information.
