  • Send email from webpage without postback/refresh

    - by jb
    Hi all. Long time reader, first time writer. Quick query i hope someone can help me with. I have a webpage (php, javascript) which has a small contact form for a user to fill in and email us. Not a problem in itself, i have a working form already. Nothing noteworthy, just a form posting to a php page which sends an email. <form id="myform" name="myform" method="post" action="Mailer.php"> So user fills in form, hits submit and the page changes to mailer.php and they find their way back to where they were. What I want instead is for the to stay on the same page when submit is pushed. The form div to update itself to just say 'message sent' or something. I just want to avoid a full page refresh. Much like how on say facebook, commenting on a status only updates that div. Hope that is phrased clearly enough. Cheers all,

  • How to use .htaccess to redirect to an url that includes a query parameter

    - by wbervoets
    Hi guys, I've been struggling with a redirect where the final URL includes a query parameter that is an URL. It seems htaccess is escaping some characters. Here is my htaccess: Code: RewriteRule ^mypath http s://www.otherserver.com/cookie?param1=123&redirectto=http://otherserver2.com/&param2=1 [L,R=302] First, if I put Code: http s://www.otherserver.com/cookie?param1=123&redirectto=http://otherserver2.com/&param2=1 in my browser address bar, www.otherserver.com will do its thing and then redirect to otherserver2 (including the &param2=1 which is a parameter of that URL and not of the URL otherserver.com) That's the behaviour I need :-) Now when I try to use the htaccess redirect from my site: http://mysite/mypath; the behaviour is not the same then putting the same URL in the browser address bar; it now tries to redirect to http ://otherserver2.com/ (no param2=1 anymore). (ps: otherserver1 and otherserver2 are not under my control.) I've tried escaping the redirectto parameter in my htaccess, like below, but it didn't work either: Code: http s://www.otherserver.com/cookie?param1=123&redirectto=http%3a%2f%otherserver2.com%2f%3fparam2%3d1 Because then my browser tries to go to httpotherserver.com (all special characters are gone) In the end I would like to see http ://mysite/mypath to show the contents of Code: http s://www.otherserver.com/cookie?param1=123&redirectto=http://otherserver2.com/&param2=1 (preferred solution) or do a redirect to that URL. I hope my message is not to confusing, I hope someone can help me out; as I've already spent hours on this :-)

  • Need for J2me source code

    - by tikamchandrakar
    For J2me It strikes me as odd that you need an extra "api key" and so on. But actually, what I really want is NOT create an extra facebook application that needs to be registered on Facebook. I don't want to create any extra configuration effords necessary for the user of my application to undergo. All my user should need is his well-known login data for facebook. Everything else should be completely transparent to him. So, I thought maybe would u can do the login process, creating a request to the REST server via http. I know this would provide me with an XML. I hope that the this API will somehow automatically transform that XML into an intuitive object model that represents the facebook user data of the respective user. So, I would expect something like userData = new FacebookData(new FacebookConnection("user_name", "password")). Done. If you get, what I mean. No api key. No secret key. Just the well-known login data. Practically, the equivalent to thunderbird webmail, which allows you to access your MSN hotmail account via Thunderbird. Thunderbird webmail will automatically converts the htmls obtained from a hotmail browser login into the data structure usually passed on to a mail client. Hope you get what I mean. I was expecting the equilalent for the your API.

  • filtering search results with php

    - by fl3x7
    Hello, Cant really find any useful information on this through Google so hope someone here with some knowledge can help. I have a set of results which are pulled from a multi dimensional array. Currently the array key is the price of a product whilst the item contains another array which contains all the product details. key=>Item(name=>test, foo=>bar) So currently when I list the items I just order by the key, smallest first and it lists the products smallest price first. However I want to build on this so that when a user sees the results they can choose other ordering options like list all products by a name, certain manufacturer, colour, x ,y ,z etc etc from a drop down box(or something similar) This is where I need some guidance. Im just not sure how to go about it or best practise or anything. The only way I can think of is to order all the items by the nested array eg by the name, manufacturer etc. but how do I do that in PHP? Hope you understand what im trying to achieve(if not just ask). Any help on this with ideas, approaches or examples would be great. Thanks for reading p.s Im using PHP5

  • Need access to views on the OnSeekBarChangeListener (which is in an own class)

    - by sandkasten
    first of all I hope you understand my english because I'am not a native speaker. Okay, I'am new to android development and try following: For my app I need a SeekBar, so I create a Seekbar via XML and implement an OnSeekBarChangeListener. In the compay I work for its forbidden (because of the styleguid) to create something like this: seekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() { @Override public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) { /// Do something } ... }); So I need to create a own class for the OnSeekBarChangeListener. So far no problem. public class SeekBarChangeListener extends SeekBar implements SeekBar.OnSeekBarChangeListener { public SeekBarChangeListener(Context context) { super(context); } public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { } public void onStartTrackingTouch(SeekBar seekBar) { } public void onStopTrackingTouch(SeekBar seekBar) { /// Do something. Following Code wont work CheckBox RemeberUsername = (CheckBox)findViewById(R.id.RemeberUsername); /// Always gets NULL } } I need a way to get access to some controls. Normaly the findViewById works fine but not in this case (what I can totaly understand, because how should the listender know about the views?). Some good hints? Or is there no oter way like the first code snippet to get the controls? Hope someone can help me out.

  • PASS: Bylaw Changes

    - by Bill Graziano
    While you’re reading this, a post should be going up on the PASS blog on the plans to change our bylaws.  You should be able to find our old bylaws, our proposed bylaws and a red-lined version of the changes.  We plan to listen to feedback until March 31st.  At that point we’ll decide whether to vote on these changes or take other action. The executive summary is that we’re adding a restriction to prevent more than two people from the same company on the Board and eliminating the Board’s Officer Appointment Committee to have Officers directly elected by the Board.  This second change better matches how officer elections have been conducted in the past. The Gritty Details Our scope was to change bylaws to match how PASS actually works and tackle a limited set of issues.  Changing the bylaws is hard.  We’ve been working on these changes since the March board meeting last year.  At that meeting we met and talked through the issues we wanted to address.  In years past the Board has tried to come up with language and then we’ve discussed and negotiated to get to the result.  In March, we gave HQ guidance on what we wanted and asked them to come up with a starting point.  Hannes worked on building us an initial set of changes that we could work our way through.  Discussing changes like this over email is difficult wasn’t very productive.  We do a much better job on this at the in-person Board meetings.  Unfortunately there are only 2 or 3 of those a year. In August we met in Nashville and spent time discussing the changes.  That was also the day after we released the slate for the 2010 election. The discussion around that colored what we talked about in terms of these changes.  We talked very briefly at the Summit and again reviewed and revised the changes at the Board meeting in January.  This is the result of those changes and discussions. We made numerous small changes to clean up language and make wording more clear.  We also made two big changes. Director Employment Restrictions The first is that only two people from the same company can serve on the Board at the same time.  The actual language in section VI.3 reads: A maximum of two (2) Directors who are employed by, or who are joint owners or partners in, the same for-profit venture, company, organization, or other legal entity, may concurrently serve on the PASS Board of Directors at any time. The definition of “employed” is at the sole discretion of the Board. And what a mess this turns out to be in practice.  Our membership is a hodgepodge of interlocking relationships.  Let’s say three Board members get together and start a blog service for SQL Server bloggers.  It’s technically for-profit.  Let’s assume it makes $8 in the first year.  Does that trigger this clause?  (Technically yes.)  We had a horrible time trying to write language that covered everything.  All the sample bylaws that we found were just as vague as this. That led to the third clause in this section.  The first sentence reads: The Board of Directors reserves the right, strictly on a case-by-case basis, to overrule the requirements of Section VI.3 by majority decision for any single Director’s conflict of employment. We needed some way to handle the trivial issues and exercise some judgment.  It seems like a public vote is the best way.  This discloses the relationship and gets each Board member on record on the issue.   In practice I think this clause will rarely be used.  I think this entire section will only be invoked for actual employment issues and not for small side projects.  In either case we have the mechanisms in place to handle it in a public, transparent way. That’s the first and third clauses.  The second clause says that if your situation changes and you fall afoul of this restriction you need to notify the Board.  The clause further states that if this new job means a Board members violates the “two-per-company” rule the Board may request their resignation.  The Board can also  allow the person to continue serving with a majority vote.  I think this will also take some judgment.  Consider a person switching jobs that leads to three people from the same company.  I’m very likely to ask for someone to resign if all three are two weeks into a two year term.  I’m unlikely to ask anyone to resign if one is two weeks away from ending their term.  In either case, the decision will be a public vote that we can be held accountable for. One concern that was raised was whether this would affect someone choosing to accept a job.  I think that’s a choice for them to make.  PASS is clearly stating its intent that only two directors from any one organization should serve at any time.  Once these bylaws are approved, this policy should not come as a surprise to any potential or current Board members considering a job change.  This clause isn’t perfect.  The biggest hole is business relationships that aren’t defined above.  Let’s say that two employees from company “X” serve on the Board.  What happens if I accept a full-time consulting contract with that company?  Let’s assume I’m working directly for one of the two existing Board members.  That doesn’t violate section VI.3.  But I think it’s clearly the kind of relationship we’d like to prevent.  Unfortunately that was even harder to write than what we have now.  I fully expect that in the next revision of the bylaws we’ll address this.  It just didn’t make it into this one. Officer Elections The officer election process received a slightly different rewrite.  Our goal was to codify in the bylaws the actual process we used to elect the officers.  The officers are the President, Executive Vice-President (EVP) and Vice-President of Marketing.  The Immediate Past President (IPP) is also an officer but isn’t elected.  The IPP serves in that role for two years after completing their term as President.  We do that for continuity’s sake.  Some organizations have a President-elect that serves for one or two years.  The group that founded PASS chose to have an IPP. When I started on the Board, the Nominating Committee (NomCom) selected the slate for the at-large directors and the slate for the officers.  There was always one candidate for each officer position.  It wasn’t really an election so much as the NomCom decided who the next person would be for each officer position.  Behind the scenes the Board worked to select the best people for the role. In June 2009 that process was changed to bring it line with what actually happens.  An Officer Appointment Committee was created that was a subset of the Board.  That committee would take time to interview the candidates and present a slate to the Board for approval.  The majority vote of the Board would determine the officers for the next two years.  In practice the Board itself interviewed the candidates and conducted the elections.  That means it was time to change the bylaws again. Section VII.2 and VII.3 spell out the process used to select the officers.  We use the phrase “Officer Appointment” to separate it from the Director election but the end result is that the Board elects the officers.  Section VII.3 starts: Officers shall be appointed bi-annually by a majority of all the voting members of the Board of Directors. Everything else revolves around that sentence.  We use the word appoint but they truly are elected.  There are details in the bylaws for term limits, minimum requirements for President (1 prior term as an officer), tie breakers and filling vacancies. In practice we will have an election for President, then an election for EVP and then an election for VP Marketing.  That means that losing candidates will be able to fall down the ladder and run for the next open position.  Another point to note is that officers aren’t at-large directors.  That means if a current sitting officer loses all three elections they are off the Board.  Having Board member votes public will help with the transparency of this approach. This process has a number of positive and negatives.  The biggest concern I expect to hear is that our members don’t directly choose the officers.  I’m going to try and list all the positives and negatives of this approach. Many non-profits value continuity and are slower to change than a business.  On the plus side this promotes that.  On the negative side this promotes that.  If we change too slowly the members complain that we aren’t responsive.  If we change too quickly we make mistakes and fail at various things.  We’ve been criticized for both of those lately so I’m not entirely sure where to draw the line.  My rough assumption to this point is that we’re going too slow on governance and too quickly on becoming “more than a Summit.”  This approach creates competition in the officer elections.  If you are an at-large director there is no consequence to losing an election.  If you are an officer the only way to stay on the Board is to win an officer election or an at-large election.  If you are an officer and lose an election you can always run for the next office down.  This makes it very easy for multiple people to contest an election. There is value in a person moving through the officer positions up to the Presidency.  Having the Board select the officers promotes this.  The down side is that it takes a LOT of time to get to the Presidency.  We’ve had good people struggle with burnout.  We’ve had lots of discussion around this.  The process as we’ve described it here makes it possible for someone to move quickly through the ranks but doesn’t prevent people from working their way up through each role. We talked long and hard about having the officers elected by the members.  We had a self-imposed deadline to complete these changes prior to elections this summer. The other challenge was that our original goal was to make the bylaws reflect our actual process rather than create a new one.  I believe we accomplished this goal. We ran out of time to consider this option in the detail it needs.  Having member elections for officers needs a number of problems solved.  We would need a way for candidates to fall through the election.  This is what promotes competition.  Without this few people would risk an election and we’ll be back to one candidate per slot.  We need to do this without having multiple elections.  We may be able to copy what other organizations are doing but I was surprised at how little I could find on other organizations.  We also need a way for people that lose an officer election to win an at-large election.  Otherwise we’ll have very little competition for officers. This brings me to an area that I think we as a Board haven’t done a good job.  We haven’t built a strong process to tell you who is doing a good job and who isn’t.  This is a double-edged sword.  I don’t want to highlight Board members that are failing.  That’s not a good way to get people to volunteer and run for the Board.  But I also need a way let the members make an informed choice about who is doing a good job and would make a good officer.  Encouraging Board members to blog, publishing minutes and making votes public helps in that regard but isn’t the final answer.  I don’t know what the final answer is yet.  I do know that the Board members themselves are uniquely positioned to know which other Board members are doing good work.  They know who speaks up in meetings, who works to build consensus, who has good ideas and who works with the members.  What I Could Do Better I’ve learned a lot writing this about how we communicated with our members.  The next time we revise the bylaws I’d do a few things differently.  The biggest change would be to provide better documentation.  The March 2009 minutes provide a very detailed look into what changes we wanted to make to the bylaws.  Looking back, I’m a little surprised at how closely they matched our final changes and covered the various arguments.  If you just read those you’d get 90% of what we eventually changed.  Nearly everything else was just details around implementation.  I’d also consider publishing a scope document defining exactly what we were doing any why.  I think it really helped that we had a limited, defined goal in mind.  I don’t think we did a good job communicating that goal outside the meeting minutes though. That said, I wish I’d blogged more after the August and January meeting.  I think it would have helped more people to know that this change was coming and to be ready for it. Conclusion These changes address two big concerns that the Board had.  First, it prevents a single organization from dominating the Board.  Second, it codifies and clearly spells out how officers are elected.  This is the process that was previously followed but it was somewhat murky.  These changes bring clarity to this and clearly explain the process the Board will follow. We’re going to listen to feedback until March 31st.  At that time we’ll decide whether to approve these changes.  I’m also assuming that we’ll start another round of changes in the next year or two.  Are there other issues in the bylaws that we should tackle in the future?

  • Public free time server

    - by JL.
    I need to get the current datetime from a reliable source, because its likely that the local system time could be changed. Is it possible to get this from an internet time server, one that has close to 100% uptime, preferably via a webservice method, something that is free, and I have to stress absolutely reliable? I would hope an offering from Microsoft, or the organisation responsible for keeping global time.

  • What is "The" book for database design?

    - by FarmBoy
    In programming, there is often a canonical book for a particular topic, like the dragon book for compilers, K&R for C, etc. Is their a book regarding modern database design that simply must be read by anyone that would hope to eventually design databases? I'm not looking for a bunch of recommendations here. The answer I'm looking for is either "Yes, it's [Title, author]." or "No, there are many good books on databases, but no one must-read."

  • Problem virtualizing Ubuntu 10.04 32 bit on VirtualBox 3.1 on Windows Vista 64 bit

    - by Adam Siddhi
    Software & Hardware Setup Host System : Windows Vista Home Premium SP1 64 bit Guest : Ubuntu 10.04 (ubuntu-10.04-desktop-i386.iso) 32 bit VM : VirtualBox 3.1.8 Hardware : Intel Core 2 Duo T6400 4GB SDRAM What Happened I followed the tutorial called Installing Ubuntu inside Windows using VirtualBox located here: www.psychocats.net/ubuntu/virtualbox At first I downloaded ubuntu-10.04-desktop-amd64.iso because I figured that it would be a perfect fit with my Vista 64 OS. I was wrong because it turns out the my Intel Core 2 Duo T6400 CPU does not have Intel® Virtualization Technology. So I had to go with the ubuntu-10.04-desktop-i386.iso which is 32 bit. This got me to the point where I could actually create the Ubuntu VM. So I set up the VM in VirtualBox (according to the tutorial I was following) to prepare for the Ubuntu 10.04 virtualization. Please go to my Picassa web album to see the screen shots of my VM settings and Ubuntu boot process so you can see what I experienced (they appear in the order that I experienced them in). www.picasaweb.google.com/rubysiddhi/ProblemVirtualizingUbuntu100432BitOnVirtualBox31OnWindowsVista64# The first 17 images show the VM settings. The last 8 show my attempt at virtualizing Ubuntu 10.04. You can see booting up but ultimately failing. The Specifics The one error message I got was: (process:210): GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0) It appeared on a black screen that sort of looked like a Windows console screen but with out the c:\ or the ability to type. Then this error message got more complex when tons of text appeared in the screen. Pictures 23 - 25 in the album show this text. I should also mention that I found this post in the Ubuntu forums by zonination who seemed to have similar problems to mine even though they had a different set up. The main issue I think zonination and me may be having is the fact that we can not change the color mode to 32 bit while it is booting. I think the 16 bit color mode maybe making Ubuntu fail. Not certain though. Well I hope I explained my problem thoroughly and clearly. Thanks for the tutorial. It got me started but, now I hope to finish this process so I can start developing in Ubuntu. OH by the way if you want to actually see what happened play by play (with some classical in the background) check out the video I made over here: http://www.youtube.com/watch?v=XMbbm5E_0Xw Thanks!

  • How practical is using a Wireless-N router together with a B and G router?

    - by Jian Lin
    I hope to use a Wireless N router to boost up the speed of wireless Internet, but there are some device that probably only supports B or G, such as iPhone, iPad, Wii, so if it is to replace the existing Wireless-B/G router, then some device won't work. Is it practical to buy a Wireless-N router, and then just plug the existing wireless router to it, or if I am using AT&T's u-verse, which has a central Wireless-B/G router, then plug in a new Wireless-N router into it?

  • iPhone 3G refuses to transfer purchased apps to iTunes

    - by andynormancx
    My iPhone 3G refuses to transfer purchased apps to iTunes. This is causing me major problems with syncing. Whenever I attempt to transfer apps from the iPhone to iTunes it goes through the motions, but never actually transfers anything. It displays the various apps in the info area at the top of the screen, but the progress bar never advances. In comparison when I sync other iPhones, using the same install of iTunes, the progress bar advances and apps are transferred. The same also happens on clean installs of iTunes on other computers, it seems to be my iPhone that is the common factor. I have tried restoring the phone from a backup, which makes no difference. This started happening months ago and the phone has since been upgraded to 3.0 and 3.1, but the problem still persists. Originally it was just a minor irritation, but I made and attempt to fix it which has made things worse. I deleted all the apps from with iTunes and then did "Transfer purchases" in the hope that it might fix something. It didn't fix anything. Also, I cannot now sync at all. If I do sync iTunes now does "transferring purchases", fails to transfer and then deletes all the apps (and data) from my iPhone. It also means I can't sync music, podcasts or anything else. I can't sync anything else, because I can't temporarily turn off app syncing because then iTunes warns that the apps on the iPhone will be deleted. I also tried de-authorising and re-authorising. What can I do to get app syncing working again ? P.S. I have considered deleting all the apps and reinstalling them one by one, in the hope that it will fix the problem. However I don't really want to embark on doing that for 55+ apps and re-entering login details etc for the apps that need them, especially as I might then find out it didn't solve the problem. Update: The latest update to iTunes 9 has improved things in one key aspect. If I let a sync run to completion iTunes no longer deletes all the apps from my phone. So I can now sync all my other data, even if I still can't sync my apps. Resolved: See my answer to the question for how I finally resolved the problem.

  • Detach current session and attach to another session, done with one script, can I?

    - by Jimm Chen
    After reading the vague official doc of GNU screen( http://www.gnu.org/software/screen/manual/screen.html ) and asking quite some questions at this site. I still cannot figure out how to accomplish such a task with a shell script. This task costs some words to describe. Assume I'm using PuTTY to telnet into my Linux server. ?STEP 1? Launch 2 telnet connections . From putty window 1 (PTWIN1),telnet into Linux Bash shell, execute screen -RR to launch a screen session, and get session name 21385.pts-4.linux-ic37 . From putty window 2 (PTWIN2), do that same as in PTWIN1, but this time, I get session name 22041.pts-9.linux-ic37 . Now, we have two screen sessions running simultaneously. We can check this: $ screen -ls There are screens on: 22041.pts-9.linux-ic37 (Attached) 21385.pts-4.linux-ic37 (Attached) 2 Sockets in /var/run/uscreens/S-chj2. ?STEP 2? Assume that for some reason, PTWIN1's TCP connection is lost abnormally(but server doesn't know that), and an urgent work is pending on session 21385 and I want to quickly regain control of it. Fortunately, we know the 21385 session is still there, so, I want to have PTWIN2 attach to session 21385. Because I hate to remember the esoteric screen option all the time, so I decide to write a script called sttach. I hope that sttach 21385.pts-4.linux-ic37 can let me attach to session 21385(for PTWIN2). Now, let's say sttach works well and I take control of 21385 on PTWIN2. ?STEP 3? Some minutes later. I want to go back to work on session 22041. Here, please allow me to have PTWIN2 remain associated with session 21385. What I would like to do is to launch another putty window (PTWIN3), telnet into server, and execute sttach 22041.pts-9.linux-ic37 in hope that I can resume session 22041 on PTWIN3 . You can see the benefit of sttach: as long as I know the target session name, I can call it to have my PuTTY window switch to that session, regardless whether the target session is "(Attached)" or "(Detached)", and regardless whether the running context is inside a screen session or not. Now the question: How to write the (Bash) script sttach? I mean, run screen with appropriate options in sttach to accomplish the goal. Waiting for your kind answer. Thank you. My previous questions regarding GNU screen: GNU screen, how to get current sessionname programmatically Is it possible to change GNU screen session name after created? How do I know I'm running inside a linux "screen" or not? My env: openSUSE Linux 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06
