• Session variables return completely after unsetting.

  - by RemiX

  I have a script that should log the user out of the site. It unsets all $_SESSION and $_COOKIE variables related to the login data of the user. But somehow, it seems impossible to log out. I checked the $_SESSION array at the end of the logout script, and at the beginning of each page. At the end of the logout script it says 'array()', but when I click the home button - or any link on the site - the full session data is back again and I don't know where it comes from. This is how I try to unset the session data: unset($_SESSION); unset($_COOKIE["usid"]); unset($_COOKIE["pw"]); unset($_COOKIE["adm"]); -- I don't know how to put it on different lines, but it's not that hard to read. Why do these data keep coming back?!

• Java training for .NET developers?

  - by C Keene

  We are working with a large retail bank on training 40-50 .Net developers to use Java. They are familiar with C# and .Net framework and have built dozens of "run the business" style apps in .Net. We need advice on how to provide basic Java familiarity, with a focus on back end logic, security and transaction management. Back end is Spring/Hibernate, front end is Ajax (Dojo). Are there any online, self-paced, Java courses that would be good for C#/.Net developers to get up to speed quickly?

• after dup2, stream still contains old contents?

  - by BobTurbo

  so if I do: dup2(0, backup); // backup stdin dup2(somefile, 0); // somefile has four lines of content fgets(...stdin); // consume one line fgets(....stdin); // consume two lines dup2(backup, 0); // switch stdin back to keyboard I am finding at this point.. stdin still contains the two lines I haven't consumed. Why is that? Because there is just one buffer no matter how many times you redirect? How do I get rid of the two lines left but still remember where I was in the somefile stream when I want to go back to it?

• rails respond_to and various forms of html responses

  - by lukewendling

  I often use respond_to do |format| ... end in Rails for my Restful actions, but I don't know what the ideal solution is for handling various forms of, say, html responses. For instance, view1 that calls action A might expect back html with a list of widgets wrapped in a UL tag, while view2 expects the same list of widgets wrapped in a table. How does one Restfully express that not only do I want back an html formatted response, but I want it wrapped in a table, or in a UL, OL, options, or some other common list-oriented html tag?

• How can I send Data from BroadcastReceiver to Widget?

  - by Yverman

  I have a BroadcastReceiver which loads data from the Internet and then it should send them back to a Widget. But how can I do this? What I've already done is updating the Widget directly from the Broadcast, but I like to just send de data back. public class UpdateManager extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context); RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget); ComponentName thisWidget = new ComponentName(context, Widget.class); remoteViews.setTextViewText(R.id.widget_textview, "UPDATE DONE"); appWidgetManager.updateAppWidget(thisWidget, remoteViews); } }

• What weird encoding is movistar Venezuela sms on blackberry using?

  - by cjp

  Send an sms using the normal GSM TextMessage API on the BlackBerry, get back garbage. It's not unicode, phone is set to 7-bit send. Byte size is only off by one. Is there some default crypto thing, or some weird encoding they use? This code works most everywhere else in the world; this definitely seems like a movistar problem. The string that comes back is random 7-bit ascii except for a few high order bytes. Needless to say the source input text is totally 7 bit chars, which should work in sms, ISO-8859 and look the same in UTF charsets. Anybody seen this or got sms working in code on movistar VZ blackberries?

• jQuery/Javascript problem with IE

  - by Shadyn

  I have two radio buttons each with a unique ID. When one is clicked, I would like to add $10 to a total. When the other is clicked, we go back to the original total price. My jquery looks like this: function check_ceu() { var price = <%= conference_price %>; if($('#ceu_yes').is(':checked')){ $('#total').val(parseFloat(price) + 10) } else{ $('#total').val(price) } } I have this function bound to document.ready (for page refreshes) and also the onchange handler of the radio buttons. In FF and Chrome this works fine. In IE, when the radio button with ID of "ceu_yes" is checked nothing happens, then when clicking back to the other radio button, 10 is added. So in essence, IE has the checkbox functionality reversed. Below is my code for the buttons: <input type="radio" name="ceu" id="ceu_yes" value="1" onchange="check_ceu()" /> $10 <input type="radio" name="ceu" id="ceu_no" value="0" checked="checked" onchange="check_ceu()" /> No, thank you Any ideas on this?

• ASP.NET jQuery Ajax posting forms

  - by Sir Psycho

  Hi, I can't seem to get the jQuery.ajax() function posting back any of my asp.net generated form controls. I've put a break point on the server side and there aren't any values. Is there a way around this or do I have to build up a list of what I want sent back? Another question slightly off topic, but it seems that although jQuery is a great JS library, it doesn't seem to integrate too well with .net. Has anyone given up with jQuery to perform server side interaction and just gone with ms ajax implementation?

• How to restore files that were removed by git?

  - by Ryan

  I am a git noob and git just deleted a bunch of important files. How do I get them back? I have a repo on my local machine. To get into git, I just right click my project folder and select "git bash here". This brings up the master where I do all my giting. So I had some changes to stage and I did: git add . This staged a bunch of changes. I noticed that I didn't want some of these staged so I decided that I'd try to unstage everthing. I did this: git reset --hard HEAD^ This basically deleted a bunch of files that I had made on the last commit and jumped to the commit before. How do I get those files back? If I can't do it through git is there another way?

• Key Events in TabActivities?

  - by stormin986

  I have a TabActivity and want to catch and handle presses of HOME and BACK. Where do I need to catch these events? In my subclass of TabActivity I implement the following: @Override public boolean onKeyDown(int keyCode, KeyEvent event) { switch (keyCode) { // Code handling } return super.onKeyDown(keyCode, event); } Didn't work. So I placed a breakpoint on the switch statement line. But this function never gets called, whether I press volume up/down, menu, home, or back. Where do I need to catch these KeyEvents?

• SVN: change a past revision and have the change in current

  - by John Isaacks

  ok say I am on revision 4. I check it out, make some change and commit it. I am not on revision 5. I check it out again, am making some changes, but I am informed that there was a typo from revision 5 that needs to be changed right away. I don't want to fix it in my current working copy because I am in the middle of something and it wont be ready to commit yet. But I don't want to revert back to revision 5 and loose all my work. what I want to do is go back to revision 5, make the small change, commit it. And ALSO have that change made to my current working copy as well. I hope that makes sense. Is there a way to do that?

• 2 ajax forms on the same page posting same textbox

  - by rod

  Hi All, Is it possible to post, say like a value in a textbox, to 2 different ajax forms that are on the same page? It doesn't have to be at the same time? What I'm trying to do is this: I have a search page that searches for customers and displays them on a paged grid. Users can specify up to 5 parameters (5 textboxes) to narrow the search. On the same page I have an export option. Well since I want all the customers for the search and not just the paged data I need a way to post back to the server for this option passing the same parameters used in the grid. I'm using a ViewModel which would be nice if I can pass that back to the server rather than the individual search fields that are backed by the view model. Thanks, rodchar

• Call other activities in an activity?

  - by Mohit Deshpande

  Say I have 2 activities (ActivityOne and ActivityTwo). How would I call ActivityTwo from ActivityOne? Then how would I return to ActivityOne from ActivityTwo? For example, I have a listview with all the contacts on the host phone. When I tap on a contact, another activity shows information and allows editing of that contact. Then I could hit the back button, and I would go back to the exact state that ActivityOne was in before I called ActivityTwo. I was thinking an Intent object, but I am not sure. Could someone post some code?

• What do I use for a J2ee website?

  - by johnny

  Not sure if I asked this correctly. I am trying to see what I need to create an website that uses MVC and that connects to legacy multiple databases, brining back those database info into one page. I wanted the site to be MVC but am not sure where to begin. Do I use Spring? What do I use for an server? Jboss and apache? Hibernate? I'm just kind of lost on how to proceed. It's not a straight forward a asp.net mvc or a php framwork. A major concern is the collection of data from multiple legacy databases and bringing that data back into one page. Thanks.

• why is the address bar black in Google chrome so you cannot see what you're typing ? [closed]

  - by Tim

  The address bar background color in Google Chrome is black. I cannot see what I'm typing. What's going on? This is a problem when you're typing in a URL you've never used before (so there's no matching history). Type in a URL you've never used before. Imagine someone is giving it to you over the phone. Make a typo somewhere. Use the back arrow to go back and correct it. You cannot see where the cursor is. This just started happening yesterday. I'm on WinXP Pro.

• web-development: how do you usually handle the "under costruction" page"?

  - by Patrick

  hi, I was wondering what's the best way to switch a website to a temporary "under costruction" page and switch it back to the new version. For example, in a website, my customer decided to switch from Joomla to Drupal and I had to create a subfolder for the new CMS, and then move all the content to the root folder. 1) Moving all the content back to the root folder always create some problems with file permissions, links, etc... 2) Creating a rewrite rule in .htaccess or forward with php is not a solution because another url is shown including the top folder. 3) Many host services do not allow to change the root directory, so this is not an option since I don't have access to apache config file. Thanks

• C# Object Array CopyTo links both arrays' values?

  - by Dutchie432

  Okay, I have what I think is a simple question.. or just a case of me being a C# beginner. I have an array of custom objects (clsScriptItem) that I am populating from a database. Once the items are loaded, I want to back them up to "backup" array so I can revert the information back after changing the main array. However, when I use CopyTo to copy the array and then alter the original array, the backup array is also being altered... I though CopyTo merely copied values + structure from one array to another. private void backupItems() { lastSavedItems = new clsScriptItem[items.Length]; items.CopyTo(lastSavedItems, 0); //items[0].nexts[0] is 2 //lastSavedItems[0].nexts[0] is 2 items[0].nexts[0] = "-1"; //items[0].nexts[0] is -1 //lastSavedItems[0].nexts[0] is also -1 } How do I backup this data without having the two arrays be 'linked'??
