  • How to access values of dynamically created TextBoxes

    - by SAMIR BHOGAYTA
    If one adds controls dynamically to a page and wants to get their information after PostBack, one needs to recreate these elements after the PostBack. Let's consider the following idea: First you create some controls: for(int i=0;i TextBox objBox = new TextBox(); objBox.ID = "objBox" + i.ToString(); this.Page.Controls.Add(objBox); } After PostBack, you want to retrieve the text entered in the third TextBox. If you try this: String strText = objBox2.Text; you'll receive an exception. Why? Because the boxes have not been created again and the local variable objBox2 simply not exists. How to retrieve the Box? You'll need to recreate the box by using the code above. Then, you may try to get its value by using the following code: TextBox objBox2; objBox2 = this.Page.FindControl("objBox2") as TextBox; if(objBox2 != null) Response.Write(objBox2.Text);

  • Appropriate level of granularity for component-based architecture

    - by Jon Purdy
    I'm working on a game with a component-based architecture. An Entity owns a set of Component instances, each of which has a set of Slot instances with which to store, send, and receive values. Factory functions such as Player produce entities with the required components and slot connections. I'm trying to determine the best level of granularity for components. For example, right now Position, Velocity, and Acceleration are all separate components, connected in series. Velocity and Acceleration could easily be rewritten into a uniform Delta component, or Position, Velocity, and Acceleration could be combined alongside such components as Friction and Gravity into a monolithic Physics component. Should a component have the smallest responsibility possible (at the cost of lots of interconnectivity) or should related components be combined into monolithic ones (at the cost of flexibility)? I'm leaning toward the former, but I could use a second opinion.

  • Amazon Web Services Free Trial: query about get and put requests

    - by abel
    Amazon recently introduced a free tier for its cloud offering. I signed up for AWS and while signing up for the free tier of S3, i found this As part of AWS Free Usage Tier, you can get started with Amazon S3 for free. Upon sign-up, new AWS customers receive 5 GB of Amazon S3 storage, 20,000 Get Requests, 2,000 Put Requests, 15GB of bandwidth in and 15GB of bandwidth out each month for one year. source:aws.amazon.com , emphasis mine. 20,000 GET requests & 2000 puts mean , 20,000 page views(max) and 2000 file uploads per month. Isn't that lower than what App Engine offers 43,200,000 requests per day.Am I missing some thing, please help.

  • Is porting a Windows application to Mac worth it ?

    - by mikel
    I have a C# Windows application that sells for $35, and fairly regularly receive requests for a version for OS X too. I don't have any experience with Mac so far though, and so am not sure exactly how much work that would involve and if it would be worth it. If anyone's been in a similar position, it'd be very helpful to know: Roughly how many more (%) sales can you expect by porting to Mac ? Would you say it's worth the investment of a new Macbook Pro and the time of learning and porting to Objective-C ? Thanks in advance.

  • How to forward an Internet connection to another network?

    - by Naveen
    Can somebody please make a shot & sweet tutorial telling how to forward an Internet connection to different network interfaces in Ubuntu...? This is the idea: I'm using a 3G usb modem to get Internet on my laptop ,which is: ppp0 IP=10.225.174.70 My Wifi device is: wlan0 MAC=78:e4:00:d4:3d:85 These devices are determined from ifconfig command. I want to share ppp0's internet connection with wlan0 device, so I can connect any other device to wlan0 and browse internet from that device. Making a Hotspot using Network settings GUI doesn't do the trick because the other device won't receive Internet, it just connects to wlan0. I heard iptables can do this, but I'm totally confused by the alien commands seen online. I'm no expert in networking. Please compose a clear & simple answer using the above devices. This is a huge annoying problem for iPhone & tablet users came to Ubuntu from Windows.

  • How to setup an encrypted voip structure?

    - by strapakowsky
    What is the simplest way to set up a voip structure in a Linux machine with the following features: 1) Using free software 2) For computer-to-computer calls: end-to-end encryption set by the users, unpaid, no central authority (so skype is out) 3) For computer-to-phone calls: paid or unpaid, desirable encryption on the computer side if that is even possible 4) Ability to have a number to receive calls from regular phones My research concluded that the sip protocol is the most popular. However most discussions I've read on sip are too technical and I felt it discourages the regular user who wants to just click and talk. So I put the question above and created some separate questions about privacy with sip registrars, privacy with voip suppliers, what to look for in a sip registrar, what to look for in a voip provider. As for the software, I noticed most software either don't provide encryption (eg Ekiga) or the software doesn't work nicely and the project is abandoned (eg Twinkle), so no option seemed satisfying.

  • Switch Hosts With Gmail Account Attached

    - by Wade D Ouellet
    Hi, I am transferring a client from their old host to my new one. Their domain-based gmail/apps account was connected to their old host, so when I changed the domain's name servers to the new host, naturally the gmail account stopped working. So I added the 7 MX records tho the new host's DNS and verified I own the domain on the new host's FTP but the email still isn't working. Is there something I'm missing? I added the MX records to the new host about two hours ago, is it possible it just takes longer than that? Also, outgoing mail seems to work. Members of the domain can't receive email though, just sends back an error. Thanks, Wade

  • What are Collaboration Data Objects (CDO)?

    - by Pranav
    Collaboration Data Objects or CDO, is a component that enables messaging between applications. It's something like the MFC we have in VC++ that enables us to prefer a simpler interface compared to the WIN32 API which, as an interface, still requires lots of escalation work by developers (yet very robust!). CDO is primarily built to simply the creations of messaging applications and we should keep in mind that CDO is NOT a new messaging model but is BUILT ON the MAPI architecture. It is just an extended interface that collaborates with MAPI and simplifies the programming task at hand for creation of messaging applications. CDO replaced Microsoft's earlier Active Messaging. CDO 1.2 enables us to play around with Data, send, receive emails and a host of other functions like rendering in exchange functionalities into HTML and do loads of other stuff. If you've got some firsthand experiences, a couple of tips will be great and will defiantly further my knowledge base in this area and hopefully get me a more refined understanding. Some pointers on MAPI will be pretty cool.

  • Forward TCP Connections with Iptables

    - by opc0de
    I receive connections to my server from several ip addresses I want to route these connections just like rinetd does but based on the ip the connection is coming from to connect to a specified host. Just like this: IP 10.10.12.1 => CONNECTS TO MY SERVER => MY SERVER REDIRECTS IT TO 82.12.12.1 IP 10.10.12.2 => CONNECTS TO MY SERVER => MY SERVER REDIRECTS IT TO 81.121.12.10 etc Is it possible or do I need to write my own daemon to achieve this functionality ?

  • Upgraded to 11.10 lost personal folders, Ubuntu one shows no files

    - by Kevin
    Upgraded to 11.04, from 10.10 system would only come up in terminal mode, but it told me that an additional upgrade was available and did I want to do that. Foolishly thinking that might fix the problem, I said yes. This time it did not make it all the way through the upgrade, when I came back to the computer over an hour later, the screen was filled with an error message "could not open display", had to reboot. Went to recovery mode on reboot to install nvidia module, when I rebooted system came up fine, but without carrying over my personal folders, I have the home folder, but no personal named folder in it. Came to Ubuntu One, but gives error message; File Sync error. (org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked Is the a way around this in order to restore my files? I know my files existed on Ubuntu one as of a few months ago.

  • JavaOne - Java SE Embedded Booth - Pactron Java Programmable Automation Controller (JPAC)

    - by David Clack
    Hi All, So at the last JavaOne we talked about developing a Java powered Programmable Automation Controller (JPAC) with our partner Pactron in Santa Clara. We actually demoed it running first at the Embedded Show in Germany this March. JPAC is based on a Marvell 88F6282 Kirkwood ARM SOC, we partnered with Hilsher from just outside Frankfurt, Germany for the mini pci ProfiBus controllers, Revolution Robotics from Corvallis, Oregon wrote the Java SE Embedded for ARM to Hilscher Linux driver interface. Revolution Robotics also designed the HTML5 application that runs on a Marvell ARM tablet to actually send and receive commands via ProfiBus to a slave device. We will have the system running in our booth at JavaOne this year, come take a look. If you are registered at JavaOne you can come over to the Java Embedded @ JavaOne for $100 Come see us in booth 5605 See you there Dave

  • How to retrieve old facebook/XMPP messages as well as new with kopete?

    - by searchfgold6789
    I have been considering using Kopete to use Facebook chat instead of logging on to Facebook with a web browser. That way, I can integrate messages with my KDE desktop better. The problem is, when I open Kopete, I am unable to see messages that I recieved in Facebook while Kopete was not opened. I can only see messages that I sent or received when Kopete was open. The same thing happens in Outlook.com (which is a website that connects to Facebook), Pidgin software, and other instant messaging tools. So my question is, how can I receive these messages with a desktop chat application in KDE, such as Kopete? Facebook has made their API publicly available to developers, and KDE has its own Facebook integration plugin. So it would seem achievable.

  • New Exam Score Report Process Coming Soon

    - by Paul Sorensen
    Hi Everyone! I want to give you a preview of a process change that will be coming in the next few weeks. We will soon announce a change in the way that Oracle certification candidates receive their exam scores and score reports (after they take an exam). Once the change occurs you will need to have an Oracle Web Account (in order to access your exam score). This is the account that is used to log into the Oracle website for things such as OTN access, software downloads and other Oracle services. If you already have an Oracle Web Account then you are already in good shape! If you do not have an Oracle Web Account the you should create one now (in preparation for this change)!  Look for additional announcements and detailed information in the coming weeks. Thanks,

  • Use of Service Bus in a Pub-Sub Engine

    - by JoseK
    In one of our projects, we've built a Publisher - Subscriber Engine on Oracle Service Bus. The functionality being a series of events are published and subscribers (JMS queues) receive these whenever a new event is published. We are facing some technical issues now, performance-wise and hence an architectural review is underway. Now for my questions: Architecturally the ESB has to publish events into a DB and read from the DB which users wish to be notified, then push the event onto their respective queues. There is a high amount of DB interaction and the question is whether ESB should be having such high amount of interaction with the DB in the first place? Or should there have been some alternate component responsible for doing this. Alternately is there any non-DB approach in which we can store the events and subscribers? Where else can this application data be held within the ESB context?

  • BizTalk: Sample: Context routing and Throttling with orchestration

    - by Leonid Ganeline
    The sample demonstrates using orchestration for throttling and using context routing. Usually throttling is implemented on the host level (in BizTalk 2010 we can also using the host instance level throttling). Here is demonstrated the throttling with orchestration convoy that slows down message flow from some customers. Sample implements sort of quality service agreement layer for different kind of customers. The sample demonstrates the context routing between orchestrations. It has several advantages over the content routing. For example, we don’t have to create the property schema and promote properties on the schemas; we don’t have to change the message content to change routing. Use case:  The BizTalk application has a main processing orchestration that process all input messages. The application usually works as an OLTP application. Input messages came in random order without peaks, typical scenario for the on-line users. But sometimes the big data batch payloads come. These batches overload processing orchestrations. All processes, activated by on-line users after the payload, come to the same queue and are processed only after the payload. Result is on-line users can see significant delay in processing. It can be minutes or hours, depending of the batch size. Requirements: On-line user’s processing should work without delays. Big batches cannot disturb on-line users. There should be higher priority for the on-line users and the lower priority for the batches. Design: Decision is to divide the message flow in two branches, one for on-line users and second for batches. Branch with batches provides messages to the processing line with low priority, and the on-line user’s branch – with high priority. All messages are provided by hi-speed receive port. BTS.ReceivePortName context property is used for routing. The Router orchestration separates messages sent from on-line users and from the batch messages. But the Router does not use the BizTalk provided value of this property, the Router set up this value by itself. Router uses the content of the messages to decide if it is from on-line users or from batches. The message context property the BTS.ReceivePortName is changed respectively, its value works as a recipient address, as the “To” address for the next recipient orchestrations. Those next orchestrations are the BatchBottleneck and the MainProcess orchestrations. Messages with context equal “ToBatch” are filtered up by the BatchBottleneck orchestration. It is a unified convoy orchestration and it throttles the message flow, delaying the message delivery to the MainProcess orchestration. The BatchBottleneck orchestration changes the message context to the “ToProcess” and sends messages one after another with small delay in between. Delay can be configured in the BizTalk config file as:                 <appSettings>                                 <add key="GLD_Tests_TwoWayRouting_BatchBottleneck_DelayMillisec" value="100"/>                 </appSettings>   Of course, messages with context equal “ToProcess” are filtered up by the MainProcess orchestration.   NOTES: Filters with string values: In Orchestrations (the first Receive shape in orchestration) use string values WITH quotes; in Send Ports use string values WITHOUT quotes. Filters on the Send Ports are dynamic; we can change them in run-time. Filters on the Orchestrations are static; we can change them only in design-time. To check the existence of the promoted property inside orchestration use the Expression shape with construction like this:       if (BTS.ReceivePortName exists myMessage) { …; } It is not possible in the Message Assignment shape because using the “if” statement inside Message Assignment is prohibited. Several predefined context properties can behave in specific way. Say MessageTracking.OriginatingMessage or XMLNORM.DocumentSpecName, they are required some internal rules should be applied to the format or usage of this properties. MessageTracking.* parameters require you have to use tracking and you can get unexpected run-time errors in some cases. My recommendation is - use very limited set of the predefined context properties. To “attach” the new promoted property to the message, we have to use correlation. The correlation type should include this property. [Here is a good explanation by Saravana ] The sample code is here [sorry, temporary trubles with CodePlex].

  • Mail Scanning System

    - by Mr D
    In the same way gmail can generate ads based on email content, I am looking for a way to develop a system which can: Allow users to connect their email address to our site It then would continously monitor all incomming emails From the incomming emails there would be a critera(e.g. a certain address or subject) if any of the emails matched the critea it would would be saved to a database Then once a new email had been found the users would receive an email notification will tells them to log back into the site to see it. My questions are: Would this be possible? What would be a good language to use(generally I like php, python and java) Are there any frameworks which would help do this? How would I connect the users email account to allow access to their emails(do I need a mail server?) Any advice? Thank you! If you need more information please let me know.

  • Boss solution vs Developer solution

    - by mahen23
    The problem: When we were sending newsletters to customers, there was no way to confirm if the customer already received the mail. So the boss decided to implement this idea: Boss's Idea: Each time mail was being sent, do an INSERT in a db with the title of the newsletter being sent and the email address which is receving the email address. To ensure that any email address does not receive the same email twice, do a SELECT in the table and find the title of the newsletter being sent: if (title of newsletter is found) { check to see of the email we are sending mail to is already present. if it does, do not send mail } else { send mail } MY idea: create a column called unique and mark it as UNIQUE. Each time mail was being sent, concatenate email + newsletter id and record it in the UNIQUE row. The next time we do a "mysql_affected_rows" check to see if our INSERT was successful, we send the mail, else, there is already a duplicate and no need to send it.

If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more detail. Additionally, I can't open the Windows Partition. I've tried updating it many times but it won't show up on GRUB. Does anybody know what all this means? And how I might fix it? I thank you for any help in advance

  • CCUserDefault, iOS/Android and game updates

    - by Luke
    My game uses cocos2d-x and will be published on iOS platform first, later on Android. I save a lot of things with CCUserDefault (scores, which level was completed, number of coins taken, etc...). But now I have a big doubt. What will happen when the game will receive its first update? CCUserDefault uses an XML file stored somewhere in the app storage space. This file is created and retained until one uninstalls the app. I am wondering what happens when the app is updated. Will the old XML file be maintained? Because if not, how should I handle app updates (updates in the sense that 2, 3 or more new level packages will be added, but the informations about the old ones, like scores, which level was finished and which not, number of coins, etc., need absolutely not to be lost)?

  • How can I reply to email by sending a delivery failure message?

    - by wau
    Occasionally, I receive unwanted emails, particularly low-volume spam, or email messages falsely addressed to me (possibly due to typos). I don't want to spend the energy to write a personal message, but I do want to let the sender know that the message never arrived at its destination, and that resending it will be useless. In my opinion, a delivery error message to the sender will fill that need. So, the question is if there is an easy way to send error messages back to the sender. Is there any email client out there which supports sending delivery failure messages as a reply to incoming email -- ideally in one click? (Or, which can be configured to do so?) Alternatively, what is the best way to set up an environment that allows me to send delivery failure messages without too much effort per message sent?
