Get Attachment file ???

[minhle3012]

Can anybody please tell me how can I get an attachment file in my message over SOAP API ?

At now, when I get an message, all attachment info I know is

<ns2:mp ns2:filename="abc.txt" ns2:cd="attachment" ns2:ct="application/octet-stream" ns2art="2" ns2:s="237534"/>

I know name, I know Id file but I can't get this attachment file into my computer

Thanks

Exactly, I found out a tag, which support get attachment file from mail :

<GetMsgPartRequest>
<m id="m1234">
<mp part="2.1.3"/>
</m>
</GetMsgPartRequest>

<GetMsgPartResponse>
<m id="...">
<mp part="2.1.3" ct="image/jpeg">
<content cte="base64">RKZezlj1hXbfPePrfm...rOIfTMUY=</content>
</mp>
</m>
</GetMsgPartResponse>

And response we had is binary byte of attachment file. But I don't know why request : GetMsgPartRequest is not run.

Is there anybody know why ?
