  • how to use multiple $_name using extends Zend_Db_Table_Abstract in zend frame work.

    - by karthik
    we tried to give our tables(users,messages) like this in two different abstract classes but it is not working. This is included in a file childconnect1.php ,is there any relation between the file name(childconnect1.php) and the class(Application_Model_childconnect1). class Application_Model_childconnect1 extends Zend_Db_Table_Abstract { protected $_name = 'users'; public function loginvalidation($username,$pwd) { $row = $this->fetchRow('UserName = \'' . $username . '\'and UserPW = \''. $pwd . '\''); if (!$row) { $msg="invalid"; return $msg; } else { return $row->toArray(); } } } class Application_Model_childconnect2 extends Zend_Db_Table_Abstract { protected $_name = 'messages'; public function replymessage($message) { $data=array( 'MessageText'=>$message ); $this->insert($data); } }

  • NoSQL for concurrent reads/writes

    - by Mickael Marrache
    After getting some performance issues for an application using a MySQL database, I'm thinking of using NoSQL solutions. My architecture is as follows: One application receives messages from the network at a high throughput (i.e. 50000 messages/sec). Each message is stored in the DB, so it's important for the write rate to be as fast as the arrival rate. Then, I also have some PHP pages that accesses the DB to get the data stored by the other application. It's important for me that the retrieved data is as relevant as possible (i.e. not old data, let's say not more than 5 seconds old). Also, the data is not critical, so I don't need any security mechanism to avoid losing the data. I see there are a lot of NoSQL solutions, but I don't know if they are all relevant. Could you please provide me some directions. Thanks

  • Is there such a thing as a dektop application event aggregator, similar to that used in Prism?

    - by brownj
    The event aggregator in Prism is great, and allows loosely coupled communication between modules within a composite application. Does such a thing exist that allows the same thing to happen between standalone applications running on a user's desktop? I could imagine developing a solution that uses WCF with TCP binding and running inside Windows Process Activation Service. Client applications could subscribe or publish events to this service as required and it would ensure all other listeners get notified of events as appropriate. Using TCP would enable event messages to be pushed out to clients without the need for polling, ensuring messages are delivered very quickly. I can't help but think though that such a thing would already exist... Is anyone aware of something like this, or have any advice on how it may be best implemented?

  • Hosting an NServiceBus subscriber in the same application as the producer.

    - by Jack Ryan
    Is it possible to use NServiceBus to publish and consume messages in the same application, specifically a web application? In the future we will almost certainly need to maintain a separate long running service to process messages generated by this application, and this is why we are hoping to use NServiceBus from the start, but right now it would be nice to just start up the consumer and the publisher when the web application starts. This will make testing and deployment far easier for us. I presume I will need to reference the NServiceBus.Host.exe and start up the process in the global.asax, but need help on what exactly I need to call to do this.

  • System.Net.Mail.SmtpClient cannot authenticate against a POP3 server, right?

    - by Herchu
    One of our customer seems to have a very old email system, those that ask you to authenticate to the POP3 server before allowing you to send messages through the SMTP server. Regrettably, we have to believe in what our customer tell us for we cannot access their facilities. But as far as I remember, years ago there were mail systems that once you log into the POP3, the STMP server is kept open for a few minutes for the client IP. Our application sends messages by using System.Net.Mail.SmtpClient which seems to be unable to authenticate to those kinds of servers. Is that correct? If so, what would be the simplest workaround? I was thinking of a minimal POP3 implementation (just the login part of the protocol). Would that work? Thanks in advance.

  • Cygwin GCC + WinXP cmd.exe does nothing

    - by Stephen Friederichs
    My basic problem is that if I run GCC from the windows command line (cmd.exe in Windows XP) and it does nothing: no .o files are created, no error messages, nothing. It will only throw an error message if I use DOS-style paths, but nothing else. When I run from the Cygwin shell then it will throws error messages as appropriate for the errors in the source and produces the .o files as it needs. Using 'make' from the DOS command line doesn't work either. Has anyone encountered this behavior before?

  • Sending an SMS myself

    - by user246114
    Hi, I'm taking shots in the dark here. I'd like to create a web service where eventually I send an SMS by using my own hardware. I'm not sure what I need in order to send an SMS myself. I don't want to use any of the existing SMS send services out there, I need to be able to send these SMS myself. It looks like there's one opensource project in particular that deals with this, "Kannel": http://www.kannel.org/ what I don't understand is, do I need to get a GSM modem to be able to send SMS? Do SMS gateways (like Kannel) eventually need to get to a GSM modem to send messages, or is there some other hardware you need to be able to actually send the messages? Thanks

  • Secure messaging using Signed MIME is it reliable?

    - by aaronb
    We have an automatic reporting and notification system written in .net that sends emails with plain text. We are having to encrypt the messages that we send our clients. The possible implementation approaches we have: Send messages as S/Mime email with attachments. Plain text email with that just contains a link to a web site that will display the message over https. It seems like S/Mime is a simpler solution, as we won't need to create the web application or secure it. Our concern is our interoperability with our clients email clients and more importantly their email filtering software. Has anyone had success or issues deploying a Signed MIME messaging solution?

  • Detect all depencies of an application

    - by Ian
    Hi All, I am in the process of "detecting" (more like listing down) all of the dependencies of our application. Currently, I am using depends.exe (Dependency Walker) to detect all of the file dependencies. I was actually able to get pass all the error messages about missing files and dependencies. However, when launching the app, all I get is a crash without any messages at all. On a "working" configuration/system, I was able to launch this app successfully. Killing a certain service will produce the "crashing" behavior. This leads me to the conclusion that SOMETHING on this service is needed by the App and this service is a dependency. However, depends.exe will not be able to "detect" this dependency. My question is: Is there an application that can programmatically detect dependencies such as Database and Services? Thanks!

  • FacesMessages and rich:effect?

    - by user331747
    I'd like to be able to make an Ajax call using JSF/Seam/RichFaces and have the page update with the relevant h:messages component. That works with no problem. I'm able to perform the appropriate reRender. However, I'd also like to be able to make use of rich:effect to make it a bit prettier. Ideally, I'd like to be able to have the messages fade in and then disappear when the user clicks on them. However, I've been unable to get this working thus far. Has anyone gotten such a scenario working? Does anyone who knows JSF/Seam a bit better than me have any good advice? Thanks in advance!

  • message queue : selection and sizing

    - by user238591
    Hi, I have 20 messages/s, each 1 - 1.5 Mbytes. I need High Availability (2 to 4 servers min). I need low latencey (high daily volume - full RAM prefered). I need persistent poisoned messages queue. Only few clients (about 16), locally. I can have 12-16G bytes RAM per server (brooker). Which JMS message queue / messaging would you recommend ? On what configuration (CPU/RAM) ? Can I propose optionnal NAS persistence (in case of final delivery failure) ? Thanks

  • HTML, jQuery Suggestion for a List

    - by AnApprentice
    Hello, I'm creating an app that will have a list of messages, each message can be either read or unread. Think GMAIL (though I'm not trying to rebuild that)... My question is when I output all these messages, I need to list if the message is read or unread, I also need to provide the ability to change the message status, from read to unread. That being said, how do you suggest I stored this? A checkbox, a hidden input value? Any thoughts? Thanks

  • Trigger on database using a web application and a winform application

    - by Michael
    Hello all, Situation: I have a web application which shows errors and where you can accept those error messages. I also have a service, which checks errors from a system and sets the error messages in the database. When I accept an error in the web application, i would like the service to know which error message has been accepted, so that it can do some other actions. My guess is that this could be done through some sort of trigger, but i can't figure out how. Can anyone help me with this?

  • Grails external Jms broker (active mq)

    - by TheBigS
    I have what will become an 'external' activemq server I'd like grails to be able to talk to. Right now I am just running it on my dev box. Here is what I have setup right now: 1) Run activemq server 2) Run activemq/examples using ant to produce messages 3) View ActiveMQ admin site: http://localhost:8161/admin/queues.jsp verify that messages are in the queue. 4) Follow Mini Tutorial to create the Service and Controller: http://www.grails.org/ActiveMQ+Plugin 5) Configured my Grails resources.groovy file as follows: beans = { jmsConnectionFactory(SingleConnectionFactory){ targetConnectionFactory = { ActiveMQConnectionFactory cf -> brokerURL = 'tcp://localhost:61616' } } } When I run the grails app I get a BindException saying port 61616 is already in use. How do I configure this to use my server that is already running? I've tried changing 'localhost' to '127.0.0.1' and to my LAN ip, but no luck, it keeps trying to setup its own embedded activemq server. Any ideas?

  • sysklogd ignores my log facilities

    - by Synther Lawrence
    I'm using sysklogd 1.5.5. All I want is to get local0 entries in /var/log/vr file. My conf: *.*;local0.none /var/log/messages local0.* /var/log/vr When I do logger -p local0.info "local0 test from logger" the message appear in /var/log/vr file. That's ok. But the following sends message to /var/log/messages instead of /var/log/vr: #include <stdlib.h> #include <syslog.h> int main(int argc, char const* argv[]) { openlog(NULL, LOG_PID, LOG_LOCAL0); syslog(LOG_INFO, "local0 test from app\n"); closelog(); return 0; } Where am I wrong?

  • Smarty dynamic error list

    - by Brainscrewer
    Im new to Smarty in combination with PHP and I really like it. Unfortunatly im running into a problem while validating fields after a $_POST has been done. I've made an array called $errors and use that to save error messages in, for example: $errors[] .= "Wrong email";. My problem is in sending the $errors array over to the template so I can use it to display the error messages. My question: How do you 'transfer' the $errors variable over to the template file so you can use it there with, for example {foreach}. I was planning on doing something like {if $hasErrors} {foreach from=errors item=error} <li>{$error}</li> {/foreach} {/if} Thanks in advance

  • Socket Programming for the Web

    - by Benny
    I have to interact with a legacy system that accepts socket communication and messages. My goal is to make the application cross-platform, but I need the ability to push messages to the client (i.e. - .NET's WCF, Java's Comet) and detect when the user closes out of their browser to destroy the socket. I have built a prototype of .NET wrapper + WCF + Silverlight but it is so disconnected it is difficult to manage the state of the user and seems to be a nightmare to support. All of that considered, what would be my best option?

' - 2 days')); $dato = "SINCE ".$dato; $messageids = $imap->search(array($dato)); any ideas on how to make zend work faster?

  • Admin panel - what is the best way to display "static" data in the layout?

    - by rkj
    I'm about to write a admin panel for my CMS written in CodeIgniter. There will be some user information visible at all time - both in the layout's header section and the sidebar. I'm used to do it in a way that I personally hope and think could be done a lot easier, since I'm tired of sending the same parametres to the view over and over again, when it's dynamic data that needs to be displayed on every page anyways (such as unread messages, username, name, status, etc). I'll need controllers and models, I know that, but do I have to pass, just for an example, the user's username, unread messages etc. every time I need to load a view? Should I do some kind of library for this? Now my question is: How would I do it when it comes to best practice and for making it easy to maintain in the future? I hope my question is understandable :)

  • Jquery JSON .each() doesnt work in Google Chrome

    - by Sheriffen
    I have a really simple chat application on a site which works pretty good. It requests by ajax like this: $.ajax({ url: "fetch/"+CHAT_SESSION_ID+"/"+LAST_MESSAGE_ID, dataType: "json", cache: false, success: function(data) { if (data.session_active == 0) { //If other chatter ended session alert("Session Ended"); } else { $.each(data.messages, function(i,msg){ alert(msg.message.Body); )}; } } }); and gets a json response that lookes like this: { "session_active": "1", "messages": [ {"message": {"MsgID": "100", "UserID": "1", "Body": "heyy"}}, ]} It works really well in at least FF and Saf but in Chrome it never gets past the .each! This is driving me nuts, have tried everything I've come across online for days but I can't seem to get it right. Please someone help! I can provide testserver if someone wants to firebug it themselves ;)

  • youtube api: display speaker statements like a caption

    - by zmol
    I'm doing something similar to close caption but not exactly the same. I have a youtube video, and I want to display certain messages at specific points in the video. When the video loads, I pull entries from the database in the format time and sentence. For example, at 0:20 the speaker says "don't forget to write down my email that you see on the side" and I want to display the email on the side. At 0:50, he says "and I'll post my office hours" so I want to show those office hours at that time. How can I do this. The video itself is hosted on youtube, but is being displayed on a private website. The div where I want to display the messages is <div id="write">.

  • Can I use MPI_Probe to probe messsages sent by any collective operation?

    - by takwing
    In my code I have a server process repeatedly probing for incoming messages, which come in two types. One type of the two will be sent once by each process to give hint to the server process about its termination. I was wondering if it is valid to use MPI_Broadcast to broadcast these termination messages and use MPI_Probe to probe their arrivals. I tried using this combination but it failed. This failure might have been caused by some other things. So I would like anyone who knows about this to confirm. Cheers.
