Storing -Downloaded Email MessagesThis tutorial explains how to store incoming email messages. - -

Introduction

You can store and restore the incoming -email message using the TDesC8 or TDesC16 function. -Ensure that you follow these guidelines while using these functions:

If you want to store -the downloaded email message data as 16 bit, then storing is slow as the downloaded -message in 8 bit should be converted to 16 bit before it is stored. However, -reading and displaying is fast as the email message data is in 16 bit.
If you want to store -the downloaded email message data as 8-bit, then reading and displaying it -is slow as the 8 bit email message data should be converted to 16 bit before -it is displayed. However, storing is fast.

Procedure

For the MTM to use CMsvPlainBodyText for -storing downloaded email messages, get the CMsvPlainBodyText object -using the InitialisePlainBodyTextForWriteL() method of CMsvStore.
Set CMsvStore to -the ID of the email message that needs to be stored, and open it in the write -mode.
Use any of the following CMsvPlainBodyText::StoreChunkL() methods -to store incoming data:
1. const TDesC8 - &aChunk, TRequestStatus &aStatus -
2. const TDesC8 &aChunk
3. const TDesC16 - &aChunk, TRequestStatus &aStatus -
4. const TDesC16 &aChunk
After the entire email -message has been received from the external server, the MTM must call the CommitL() method -of CMsvPlainBodyText to complete the store operation.

The email server MTM can store the email message that is received -from the external server either as 8 or 16 bit. When the MTM calls the 16 -bit version of the StoreChunkL() function, and based on the -charset information, it must convert the data to Unicode.

If the -8 bit version of theStoreChunkL() function is used for storing, -and if the MTM wants the email message to be stored as 16 bit (this is indicated -by the TBoolaIs8Bit parameter of InitialisePlainBodyTextForWriteL()), CMsvPlainBodyText converts -and stores the email message in 16 bit based on the charset information provided -while initialising CMsvPlainBodyText.
