  • General approach for posting business logic status messages to UI?

    - by generalt
    Hello all. I have been struggling with this question for awhile now, and I haven't reached a conclusion. I'm not typically a UI programmer, so forgive the noobishness. I'm writing a typical application with a UI layer (WPF) and a business layer. I want to post status messages to the UI from the business layer (perhaps deep within the business layer), but I don't want the business layer to have any knowledge of the UI. Is there a generally accepted pattern for this? I was thinking to have a message queue of some sort to which the business layer posts status messages, and have the view model of the UI subscribe to that queue and intercept messages from the queue and route them to the UI. Is that a good approach? Is there somewhere else I should start? Thank you.

  • How to extract messages to translate from a Play! application

    - by Martin
    I'm writing my first application using the Play! framework and I was wondering if there was a tool that could extract the messages that need translation from my views and controllers for me ? It is rather cumbersome to fill the conf/messages(.xx) file while I'm developing my app, but I'm afraid that if I don't do it as I go, I will never be able to completely translate my application afterwards. Such tools exist with other framework such as CakePHP for instance, and I think that it shouldn't be hard to write one by myself, but if there already is one... I was also wondering, what should I name the keys of the messages in my application ? Using gettext, it's not bad practice to directly type in the message in english as the key, but is it with the system that Play! uses (MessageFormat, right ?) ? Does anyone have an advice or naming convention (something like controller.action.describe_the_message maybe) ? Thank you for your advices !

  • How do I get User.message_set messages to show up for the built in test client?

    - by Conley Owens
    I'm aware that the old Django messages framework is deprecated, but I still would like to know the answer to this. When I go to a certain url to my broswer, a message is created, I am redirected to a different page, and I see the message correctly displayed by my template. When the test client goes to the same url, the message is created, it gets a redirect, and after following the redirect there are no messages. However, no messages appear in the response (the response gotten from following the redirect). Why not?

  • git - how do we verify commit messages for a push?

    - by shovas
    Coming from CVS, we have a policy that commit messages should be tagged with a bug number (simple suffix "... [9999]"). A CVS script checks this during commits and rejects the commit if the message does not conform. The git hook commit-msg does this on the developer side but we find it helpful to have automated systems check and remind us of this. During a git push, commit-msg isn't run. Is there another hook during push that could check commit messages? How do we verify commit messages during a git push?

  • Mysql query problem

    - by Sergio
    I have a problem with (for me to complicated) MySql query. Okay, here is what I need to do: First I need to check messages that some specific user received $mid=$_SESSION['user']; $stat1=mysql_query("SELECT id, fromid, toid, subject FROM messages WHERE toid = '".$mid."' AND subject != 'not readed' GROUP BY fromid ") or die(mysql_error()); while ($h = mysql_fetch_array($stat1)) { $whosend=$h['fromid']; Second thing that I need to do is check the status of the users (deleted or not) who sent the messages ("fromid") to my specific user ("toid"). This I must do from another table: $stat2=mysql_query("SELECT id, status FROM members WHERE id='".$whosend."' AND status ='1'")or die(mysql_error()); while ($s = mysql_fetch_array($stat)) { Then my problems begin to show up. How can I get the number of the users who sent messages to my specific user with status =1? Not the number of the messages but the total number of the users who sent them. Is there any easier way to do this query? I tried with join tables like $stat=mysql_query("SELECT memebers.id, memebers.status, messages.toid, messages.fromid,messages.subject,messages.id FROM members, messages WHERE messages.toid='".$mid."' AND members.status ='7' .... But even in this query I need to have id's of the user who sent messages before this query so there will be another query before this join tables.

  • How to get the Dash and HUD to appear. (and stop Unity spewing error messages.)

    - by Ubuntiac
    I just installed Ubuntu 12.04 on my wifes Dell Inspiron 1501, which uses an R300 ATI graphics chip. Neither the Dash or HUD appear when pushing the appropriate key. When I try unity --reset & in the terminal, I see that over and over it's spitting out: r300: CS space validation failed. (not enough memory?) Skipping rendering. This is just after starting Ubuntu with no apps open, so I find it hard to believe that just rendering the Dash / HUD is completely blowing out the VRAM. Any suggestions on getting this working? /usr/lib/nux/unity_support_test -p shows OpenGL vendor string: X.Org R300 Project OpenGL renderer string: Gallium 0.4 on ATI RS480 OpenGL version string: 2.1 Mesa 8.0.2 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes All sections say "YES"

  • Website that allows twitter like message accessed via tinyurl

    - by blunders
    Looking for a website that allows me to post twitter like messages that are accessed via tinyurls and that I'm able to create an account to get reports on the access of each of these messages. Basically, unlikely twitter each message would require the tinyurl to access the message, but the would be no central author index of messages, but the author would not only be able to login and see a centralized listing of all the messages, but also reports on if the messages had been accessed.

  • Will GMails Greasemoney API help me: composing and sending messages, adding a button to the compose view, listing and sending drafts [migrated]

    - by Kent
    I want to create a Greasemonkey script for GMail and I've browsed through the GMail Greasemonkey 1.0 API documentation. I haven't fully understood what the API actually provides, which leads me to ask a few concrete questions. How will the API help if I want to: Add a button to the Compose view which executes some of my code. Compose and send a new message from scratch. List the current drafts. Pick a draft and send it. From what I can see it'll help me with 1 above, but I don't see any real interaction API parts which can help me with 2-4.

  • Grub gives messages about the boot sector being used by other software. What should I do?

    - by Bobble
    This only happens with one of my computers. It is an elderly laptop that has had a long and varied history with several operating systems, but in its retirement it is acting as a server for my home network using Ubuntu 12.04. It is a single-boot system, there are no other systems installed. Every so often, whenever there is a grub upgrade, I notice a message like this: Setting up grub-common (1.99-21ubuntu3.4) ... Installing new version of config file /etc/grub.d/00_header ... Setting up grub2-common (1.99-21ubuntu3.4) ... Setting up grub-pc-bin (1.99-21ubuntu3.4) ... Setting up grub-pc (1.99-21ubuntu3.4) ... /usr/sbin/grub-setup: warn: Sector 32 is already in use by FlexNet; avoiding it. This software may cause boot or other problems in future. Please ask its authors not to store data in the boot track. Installation finished. No error reported. Should I be worried about this? What (if anything) should I do about it?

  • Design application to send messages by marking circle on the map where you want to send message

    - by jhamb
    This is question asked to me by an interviewer, in which a map of world is given, and for those country you want to send message, just marked circle on that area, and just send to all the people comes in that area. Question visual link is : Design this application The approach that I told him: Firstly build whole person's data (contacts , place information and all) Then where you mark on the map, just build a cluster of that country using Hadoop and fire the message to all the person's contact comes in that cluster. So help me for better understandings of this problem, and if have another good approach (all back-end ad front-end) , then please tell me or discuss here with me. Thanks in advance.

  • MMORPG Server architecture: How to handle player input (messages/packets) while the server has to update many other things at the same time?

    - by Renann
    Yes, the question is is very difficult. This is more or less like what I'm thinking up to now: while(true) { if (hasMessage) { handleTheMessage(); } } But while I'm receiving the player's input, I also have objects that need to be updated or, of course, monsters walking (which need to have their locations updated on the game client everytime), among other things. What should I do? Make a thread to handle things that can't be stopped no matter what? Code an "else" in the infinity loop where I update the other things when I don't have player's input to handle? Or even: should I only update the things that at least one player can see? These are just suggestions... I'm really confused about it. If there's a book that covers these things, I'd like to know. It's not that important, but I'm using the Lidgren lib, C# and XNA to code both server and client. Thanks in advance.

  • Is there a learnable filter in Thunderbird for non-spam messages (as in Opera Mail)?

    - by Debilski
    One feature I like very much about Opera Mail is that you can have learnable filters for any purpose. So not only can you filter spam messages but also messages that your friends sent you or info mails from web platforms without having to enter each and every mail address you want to filter. It actually works quite satisfying and you can combine it with string filtering, too. It does a few mistakes in the beginning but then improves quickly after you have removed some of the false positives. However, there are a couple of drawbacks with the Opera Mail module. The filters are only ‘virtual’. So, with IMAP there is no easy way of mirroring the filtered structure back on the server and when I’m using webmail I’ll see the whole unfiltered mess in the inbox folder. Opera’s not using the OS X address book — and neither does it use ldap (which is not too important for me at the moment). So, I’m not specifically looking for a Thunderbird solution here, a way to fix things in Opera or Apple Mail should do as well. Or some other E-Mail program I don’t even know about yet. (So, to be clear, I’d like to have: OS X Address Book integration, Learnable filters for any type of filtering, Ability to push filtered folder structure to the IMAP server) But I thought like, if it is possible then most probably there would be an add-on for Thunderbird available. Any ideas?

  • JavaScript: What would cause setInterval to stop firing?

    - by Rosarch
    I am writing a chat AJAX app. Randomly, in FF 3.5.9, setInterval() seems to stop firing. I don't have clearInterval() anywhere in my code. What could be causing this to happen? $(document).ready(function () { $("#no-js-warning").empty(); messageRefresher = new MessageRefresher(0); setInterval($.proxy(messageRefresher, "refresh"), 2000); }); function notifyInRoom(user) { $.getJSON('API/users_in_room', { room_id: $.getUrlVar('key'), username: user }, function (users) { if (!$.isEmptyObject(users)) { $("#users").empty(); $.each(users, function (index, username) { var newChild = sprintf("<li>%s</li>", username); $("#users").append(newChild); }); } else { $("#users-loading-msg").text("No one is in this room."); } }); } function MessageRefresher(latest_mid) { this._latest_mid = latest_mid; } MessageRefresher.prototype.refresh = function () { notifyInRoom($("#user-name").val()); var refresher = this; $.getJSON('API/read_messages', { room_id: $.getUrlVar('key'), mid: refresher._latest_mid }, function (messages) { if (! (messages == null || $.isEmptyObject(messages[0]))) { // messages will always be at least [[], [], 0] $("#messages-loading-msg").hide(); for (var i = 0; i < messages[0].length; i++) { var newChild = sprintf('<li><span class="username">%s:</span> %s</li>', messages[1][i], messages[0][i]); $("#messages").append(newChild); } refresher._latest_mid = messages[2]; setUserBlockClass(); } else { $("#messages-loading-msg").text("No messages here. Say anything..."); } }); } // Give the end-user-block class to the appropriate messages // eg, those where the next message is by a different user function setUserBlockClass() { $("#messages li").each(function (index) { if ($(this).children(".username").text() != $(this).next().children(".username").text()) { $(this).addClass("end-user-block"); } }); } I checked the most recent responses in Firebug, and it was the same responses that had been sent earlier. (So, it's not like an unusual response caused a crash.) If I refresh the page, the calls resume.

  • Livevalidation clientside validation - can you control the position of the validation messages?

    - by JK
    I'm using LiveValidaion for my clientside validation http://livevalidation.com/ and DataAnnotations for my validation rules. This all works fine except that the clientside error messages are only ever displayed to the right of the element being validated. Is it possible to move this validation message below the element being validated? Or even better, group all messages in a div at the top/bottom of the page? I dont see anything in their docs or examples

  • How to concatenate all commit messages from subversion into one text file with no metadata?

    - by user144182
    I would like to take all the commit messages in my subversion log and just concatenate them into one text file. Each commit message has this format: - r1 message - r1 message - r1 message What I would like is something like: - r1 message - r1 message - r2 message - r2 message - r3 message [...] - r1000 message Update I thought the above was clear, but what I don't want in the log is this type of info: r2130 | user| 2010-03-19 10:36:13 -0400 (Fri, 19 Mar 2010) | 1 line No meta data, I simply want the commit messages.
