[Email] Savings in base64 accessories for use in EML

I try to save e-mails to eml files. For attachments, how can I get the binaries base64 encoding?

I guess I could make a Qdatastream, but wouldn't the encoding Base64 requires reading across the folder at a time?

The bindings can be from a few kb (quick question) to 50 + mbs, can someone point me in the right direction

I think that Base64 encoding works on groups of 3 bytes at a time, so you would not need to read any attachment in a go. QByteArray has a method toBase64(), that you can use for this.

See http://www.ietf.org/rfc/rfc2045.txt where it says:

 The encoding process represents 24-bit groups of input bits as output
   strings of 4 encoded characters.  Proceeding from left to right, a
   24-bit input group is formed by concatenating 3 8bit input groups.
   These 24 bits are then treated as 4 concatenated 6-bit groups, each
   of which is translated into a single digit in the base64 alphabet.

  • Exchange server and Surface RT, can I use Mail app to connect to the Exchange Server for email (the same question is for contacts or people and calendar)?

    You must install the SSL certificate before connect you to the Regional service, the easiest way is to go to "desktop" IE10 open, go to the exchange server web access page, click on the notification of "certificate error" red and view / install the store "certificate authorities roots of trust." Then, make sure that your surface RT complies with the minimum requirements of security then connect to the exchange via the mail application server.

  • says I have emails, but not down load them - used to work properly

    says I have emails, but not down load them - used to work properly.

    For an example says that there download 1 / 6 after awhile, he says no new messages. I can check my email from another source and see that I have 6 messages and am able to read them. I ran scan programs and malware and clear up all the problems, they found that Thunderbird is not download again. I'm on the latest version 31.6.0

    This is probably one of these programs of malware or anti virus which is at the origin of the problem. Disable the e-mail in your anti virus and restart your computer. Best? What anti virus is it anyway?

  • Looking for accessories for a Satellite L655D-S5151

    I'm looking for some accessories for my Satellite L655D-S5151. The newsletter that Toshiba continues to send to me is always on new laptops. I don't need a new laptop that I just bought it. I need accessories for the one I have.

    Now I'm looking for two things:

    A graphics tablet that I can use for tracing/drawing/note taking which would be compatible with Tablet PC Input Panel and art including OpenOffice Draw programs.

    Something to replace notebooks. Something handheld or slightly larger with a database of address/phone number would be nice. I would like to be able to download the notes from the device to the laptop. I didn't need anything else. No games, camera or phone. It should be relatively inexpensive. I thought I'd do a PDA, but apparently they are obsolete. Does anyone have any suggestions? Google was not helpful.

    How about something like an Android Tablet?

  • Performance of the property as accessors for class nodes

    LV2013

    I vaguely remember reading somewhere that property nodes require a context LV switch because they must be run on the UI thread.

    • Is this always true?

    • Is true even if the node are not related to a user control (e.g., an accessor for a field of private data in a class)?

    • How much of a penalty that is? Everyone has ever measured it?

    • It is convenient to use a node property with terminals 2 + to access the fields 2 +.  Is - this comfort outweighs the drop in performance?

    • Are there any books or other documents explaining all this?

    Thank you

    That's only true property nodes that run in the user interface thread, such as those that refer to elements of façade. Executing an accessor LVOOP via a property node is just syntactic around a standard call from VI and don't force a switching of threads. I remember reading that there is a slight difference in this read accessors run always in the order due to management errors, but I can't find this post in a quick search.

  • After activation allow double E-mail which made email go when a user for forgotten user id request

    Hello

    We put IOM. False to allow identification of email EmailUniqueCheck double as 2 or more users can have the same e-mail ID.


    Scenario:


    User1 has [email protected]

    User2 has [email protected]


    When user1 click password forgotten or forgotten, the email will both users or for a single one that is asked?




    Thank you

    Its the same email address, so anyone who has access to this e-mail address will see the email when they check their mailbox.

    Generally, each user has its own address. A shared e-mail address is usually used for mailing lists, but the list contains the individual e-mail accounts, so in the user profile each user will always enter their own individual e-mail rather than the address of the mailing list.

    Some organizations that do not have this concept of mailing lists and have in fact multiple users access the same email address. In this case, if one of those users change their password or request their username, the email will be seen by all users who use this same e-mail account.

    If you don't like it, don't share an account of e-mail in the first place.

  • Eloqua data extraction for use in the analytical software

    Topliners,

    I use Eloqua 9 and I would like to extract customer information on send individual email so that I can perform trend analyses & regression in analysis tools of data to third parties such as table & SPSS.

    My hope is that I can extract the data from the customer (State / Zip Code / custom fields) and perform only basic e-mail statistics data (sent / open / click / etc...) using the email address as primary key.

    Anyone who has tried to make such a report from Eloqua or used the API to send log extract / rewrite table / customer profile data for using third-party tools?

    Any advice would be greatly appreciated.

    Thank you
