Moving messages between queues rabbitMQ

由 房东的猫 提交于 2019-12-22 05:43:10
问题 I am looking to be able to move messages between queues (manually) in Rabbit. For example: first-queue has messages ['a','b','c','d','e','f'] second-queue has messages ['x','y'] I want to be able to move for example message 'a' to second-queue from first-queue. This can be a manual operation. Both queues are on the same broker, and I do not want to send them through any exchange. Is there anyway to do this? I have been playing with rabbitmqctl but can't seem to get it to work. I am open to

CodeIgniter reusable message library

由 时间秒杀一切 提交于 2019-12-22 01:06:50
问题 I'm using Message library (http://codeigniter.com/wiki/Message/) to display error messages on my site. This is the code that I'm using to display a message: $this->message->set('error',$this->config->item('error.login')); Right now I'm storing common messages in my config file (config/config.php) instead of writing the message every time. Is there a better way to do it? The config file is getting very long. What I'm looking for is a better way to store re-usable text strings. 回答1: CodeIgniter

c#. MSMQ .The max size of a single message

由 我们两清 提交于 2019-12-21 07:12:19
问题 Using msmq I want to send a message ( near 1 GB ). I want to send array of bytes . But I can send only 4 MB . How can I get around this limitation ? 回答1: As you know the maximum size of a message in MSMQ is 4Mb, its better to go for some other solutions. Solution : If you want to transfer data that exceeds this size, you will have to cut it into chunks in the sender's side, and recombine it in the receiver side. Why is there a 4MB limit on MSMQ messages? Check out this blog. How to send files

Email body is a string sometimes and a list sometimes. Why?

由 萝らか妹 提交于 2019-12-21 04:35:11
问题 My application is written in python. What I am doing is I am running a script on each email received by postfix and do something with the email content. Procmail is responsible for running the script taking the email as input. The problem started when I was converting the input message(may be text) to email_message object(because the latter comes in handy). I am using email.message_from_string (where email is the default email module, comes with python). import email message = email.message

Implementing a message/subscription mechanism in C#

问题 I'm prototyping a WPF application with the MVVM pattern. Following an answer to this question I have set up a ModelProviderService which exposes models as properties. The consumers of the service are the viewmodels, i.e. they pull their models from the service instead of instantiating them theirselves. class ModelProviderService { private LoginModel loginModel; public LoginModel LoginModel { get { return loginModel; } set { loginModel = value; } } private ProjectsModel projectsModel; public

Send MIDI messages over USB on Android

由 爷，独闯天下 提交于 2019-12-20 11:09:36
问题 I would like to make an app on android which sends MIDI messages over USB to a computer to be able to control music softwares such as Cubase, FL, Reason, ect... Hardware MIDI controllers (e.g Keyboards) are automatically recognized in music software on Windows. I guess it's because they use the universal MIDI protocol which is directly recognized by the music software. They don't need their own driver. I'd like to be able to use my phone/tablet as a midi controller without having to install

How to determine the message status (read/unread) in chat?

问题 How to determine the message status (read/unread). Chat is realized with the XMPP protocol. 回答1: XEP-0184: Message Delivery Receipts supports notifying senders when their message has been delivered. You might be able to use that as a building block, as long as you don't expect existing clients to send these receipts -- the XEP is not widely-implemented today. 回答2: I think you need to use the Displayed Chat Marker, per http://xmpp.org/extensions/xep-0333.html 回答3: If you want to get the read

Drawing box around message

问题 I'm working on this Python task that I can't figure out. It is the last of 3 functions and the first 2 were much easier to program then this one. The instructions are "Given a message that may contain multiple lines, utilize the split() function to identify the individual lines, and the format() function so that when printed, it draws a box around the message's lines, all centered. Box uses vertical bars & dashes on the sides (|, -), +'s in the corners (+), and there is always a column of
