• browser back acts on nested iframe before the page itself - is there a way to avoid it??

  - by kfiroo

  hi, i have a page with dynamic data loaded by some ajax and lots of javascript. the page contains a list from which the user can choose and each selected value loads new data to the page. one of these data items is a url provided to an iframe. i use jQuery BBQ: Back Button & Query Library to simulate the browser-back behavior. all works well besides the fact that when i click the back button for the first time the iframe goes back to its previous location and then i need to click back again to make the page go back. is there a way to disable the iframe's back behavior?

• MouseLeftButtonDown not recognized by a ListBox ??

  - by Flo

  Hello everybody, I'm encountering a huge problem, I have tried everything I could, but I didn't find any solution. I have a listBox, with a DataTemplate. I want to use the events MouseLeftButtonDown and MouseLeftButtonUp to check the item selected is the same the user clicked on. The problem is the event MouseLeftButtonUp is recognized but not the event MouseLeftButtonDown. Part of my XAML code : < ListBox Grid.Row="1" MouseLeftButtonDown="listBox_Faits_MouseLeftButtonDown" MouseLeftButtonUp="listBox_Faits_MouseLeftButtonUp" The code behind : private void listBox_Faits_MouseLeftButtonUp(object sender, MouseEventArgs e) { ... } private void listBox_Faits_MouseLeftButtonDown(object sender, MouseEventArgs e) { ... } Is anyone know why ? Thanks you, Regards, Flo

• Change .NET Framework version of application pool to 3.5?

  - by Sean Sexton

  I've installed .NET Framework 3.5 SP1 on web server (Server 2008 Enterprise), so running IIS 7.0. I want to change the version of .NET Framework used by an existing site. So I right-click on appropriate Application Pool and selected Edit Application Pool. The .NET Framework dropdown does not include an explicit entry for framework 3.5, but just 2.0.50727. Does anyone know off the top of their head--is this just because the version of the core RTL in 3.5 is still 2.0? Or do I need to do something additional to get IIS to see version 3.5? (Did try restarting IIS). Thanks!

• ASP.NET Calendar control: HowTo stop resetting calendar when navigating Back in the browser

  - by user125873

  Hi All, I've implemented the ASP.NET Calendar control. I'm using it to show events happening in the area. THE PROBLEM Today is August 18th, so when the calendar loads, August is selected as the current month. If I navigate to say October, and then navigate to another page and then try to go back to the page with the Calendar by clicking the browser Back button, the Calendar resets back to August, instead of remaining at October. Can anyone recommend how I may circumvent this? Thanks!

• what does the @ symbol mean in ls -l directory listing?

  - by Andrew Arrow

  When I run ls -l on my mac I see two .yml files: -rw-r--r-- 1 aa staff 6 Apr 15 05:50 s1.yml -rw-r--r--@ 1 aa staff 362 Apr 15 05:49 s3.yml same owner, same permissions but one has a @ at the end of the permisions. The one with the @ shows up in my editor, the one without does not. So there must be some significance. How can I turn on the @ for the file without it? I selected the files in the finder and did get info and everything looks identical between the two files.

• MVC ASP.Net how do I add a second model to a view? i.e. Add a dropdown list to a page with a html grid?

  - by John S

  I have been able to find lots of examples of adding a Dropdown list to a view but I need to add a dropdown list to a view that also has a Webgrid on it. This entails two different models and from what I see I can only have one per view. The DDL will be filled from one model and the grid from the other. I'm just trying to filter the displayed data in the grid with the data selected in the ddl. Any examples or articles would be greatly appreciated. TIA

• Deserialized xml - check if has child nodes without knowing specific type

  - by AndyC

  I have deserialized an xml file into a C# object and have an "object" containing a specific node I have selected from this file. I need to check if this node has child nodes. I do not know the specific type of the object at any given time. At the moment I am just re-serializing the object into a string, and loading it into an XmlDocument before checking the HasChildNodes property, however when I have thousands of nodes to check this is extremely resource intensive and slow. Can anyone think of a better way I can check if the object I have contains child nodes? Many thanks :)

• How do I override ToString in C# enums?

  - by scraimer

  In the post Enum ToString, a method is described to use the custom attribute DescriptionAttribute like this: Enum HowNice { [Description("Really Nice")] ReallyNice, [Description("Kinda Nice")] SortOfNice, [Description("Not Nice At All")] NotNice } And then, you call a function GetDescription, using syntax like: GetDescription<HowNice>(NotNice); // Returns "Not Nice At All" But that doesn't really help me when I want to simply populate a ComboBox with the values of an enum, since I cannot force the ComboBox to call GetDescription. What I want has the following requirements: Reading (HowNice)myComboBox.selectedItem will return the selected value as the enum value. The user should see the user-friendly display strings, and not just the name of the enumeration values. So instead of seeing "NotNice", the user would see "Not Nice At All". Hopefully, the solution will require minimal code changes to existing enumerations. Obviously, I could implement a new class for each enum that I create, and override its ToString(), but that's a lot of work for each enum, and I'd rather avoid that. Any ideas? Heck, I'll even throw in a hug as a bounty :-)

• How to add SQL elements to an array in PHP

  - by DanLeaningphp

  So this question is probably pretty basic. I am wanting to create an array from selected elements from a SQL table. I am currently using: $rcount = mysql_num_rows($result); for ($j = 0; $j <= $rcount; $j++) { $row = mysql_fetch_row($result); $patients = array($row[0] => $row[2]); } I would like this to return an array like this: $patients = (bob=>1, sam=>2, john=>3, etc...) Unfortunately, in its current form, this code is either copying nothing to the array or only copying the last element.

• Flex / ZendAMF / PHP app, corrupted data with some linux clients problem

  - by Laurent Jégou

  Hello, i'm buiding a survey web application, using Flex for the front-end (nice forms), and a MySQL database for the storage, linked by PHP with the help of ZendAMF. I largely borrowed from this nice tutorial by Alan Gruskoff : http://digitalshowcase.biz/wordpress/?page_id=26 (The only one tutorial i've found to work with the last version of Flex). The app seems to works nicely in my tests, except on certain linux boxes : the data is somehow corrupted : there is no error message, no glitch, but the response of the forms are not what the user selected. I tried to reproduce the error on a fresh installed ubuntu VM, but it works fine. I've asked friends for some tests, and several linux users showed the same problem, on ubuntu and suse machines, all freshly updated and functionnal. The application was targeted to be the survey tool for my doctoral thesis, so i'm quite desperate here, and before i'm dumping it to start anew with php only, i'm asking here in case someone can help, thanks :-) Please excuse my english, by the way. LJ.

• Chrome Extension contenteditable get and set caret position

  - by jwize

  I am creating an extension where I need to insert a link into the gmail window. I am able to create a simple extension button in the top of the window and execute code that does replaces all the links. Now, I want to do add links in the contenteditable section as I type. It seems like there should be a simple way to replace text with a link in the document object model. If this is not true I need to do three things. Insert text from the current caret position Capture the caret position. Set the caret position by its offset. I have tried using window.getSelection within the gmail context(that is a body element that is set to contenteditable and embedded inside an iframe in the gmail tab) to get the current range and position. The selection is always empty and contains no ranges regardless of whether text is selected or not.

• Best way to choose a random file from a directory in a shell script

  - by jhs

  What is the best way to choose a random file from a directory in a shell script? Here is my solution in Bash but I would be very interested for a more portable (non-GNU) version for use on Unix proper. dir='some/directory' file=`/bin/ls -1 "$dir" | sort --random-sort | head -1` path=`readlink --canonicalize "$dir/$file"` # Converts to full path echo "The randomly-selected file is: $path" Anybody have any other ideas? Edit: lhunath makes a good point about parsing ls. I guess it comes down to whether you want to be portable or not. If you have the GNU findutils and coreutils then you can do: find "$dir" -maxdepth 1 -mindepth 1 -type f -print0 \ | sort --zero-terminated --random-sort \ | sed 's/\d000.*//g/' Whew, that was fun! Also it matches my question better since I said "random file". Honsetly though, these days it's hard to imagine a Unix system deployed out there having GNU installed but not Perl 5.

• Using a ControlParameter in FilterParameters when the property is null

  - by end-user

  I have a DataList and FormView; they have separate datasources, though they pull the same info. The FormView's datasource has a FilterExpression to pull whatever's been selected on the DataList. On first load, the SelectedValue of the DataList is null (naturally). I expect the FilterExpression to result in zero rows, but it doesn't. If I set the DefaultValue to 0, it does, but then the parameter never updates when I select something from the DataList. Am I doing it wrong?

• post data to a thickbox using ajax

  - by sqlchild

  I need to post data to a thickbox using ajax and open it immediately and display the posted data. The user would click on a link/button and the data i.e. value of the selected checkboxes would be posted to "my_thickbox.php" and the thickbox (url : my_thickbox.php) would open with checkbox values displayed. <div id="showthickbox" ><a href="my_thickbox.php" class="thickbox"></div> $('#showthickbox').click(function() { var data = $('input:checkbox:checked').map(function() { return this.value; }).get(); $.ajax({ type: 'POST', url: 'my_thickbox.php', data: data, success: success, dataType: dataType }); });

  - by Tommy

  I have a control, that moves around alot of different controls inside of it in the form of a grid. So basically, none of the container control is shown at any point. But i do have capture of all the mousedown and mousemove events of the controls inside. What id like to do, is create an effect alot like the desktop of a windows computer, where you can drag, and every control that is inside of the mouse's drag will be thrown in a list, and when the mouse is released i can perform an action on all the selected items. Is this possible?

• Nike + iPod app like customisation ?

  - by Madhup

  Hi, I am very much curious about Nike + iPod app look and feel. They have selected uitabbar buttons red in color The tableviewcell selection style as red in color. The disclosure indicator is also red in color. The solution in my mind for two of these is: I can use a red colored arrow image to use it as accessory view. I can flip between a red colored and white colored view with animation for having the selection style But I am clueless of how the tabbar thing is to be done. I am very curious to know the tricks behind this, I also accept that I may be wrong with my other two solutions. So please suggest the solution for any of the problems. I think all are worth knowing for the developers. Thanks, Madhup

• Android: Saving custom button and spinner

  - by Jacob Huggart

  Hello All, I am new to Android programming and was handed a fairly large program that is almost complete, but needed support for switching between portrait and landscape view. I added android:configChanges="keyboardHidden|orientation" to the manifest and used onConfigurationChanged to save the view data and that works. However, there is a button that displays the date selected (when pressed a calendar to select the date comes up) and a spinner that displays the current view and is used to select a new view. Those two items are being cleared/reset and do not work at all after the screen flip. I have been attempting to use onSaveInstanceState and onRestoreInstanceState to fix that, but I cannot figure out how to get it to work. Any advice?

• DataSource or ConnectionPoolDataSource for Application Server JDBC resources

  - by Vinnie

  When creating JNDI JDBC connection pools in an application server, I always specified the type as javax.sql.ConnectionPoolDataSource. I never really gave it too much thought as it always seemed natural to prefer pooled connections over non-pooled. However, in looking at some examples (specifically for Tomcat) I noticed that they specify javax.sql.DataSource. Further, it seems there are settings for maxIdle and maxWait giving the impression that these connections are pooled as well. Glassfish also allows these parameters regardless of the type of data source selected. Are javax.sql.DataSource pooled in an application server (or servlet container)? What (if any) advantages are there for choosing javax.sql.ConnectionPoolDataSource over javax.sql.DataSource (or vice versa)?

• Accessing functions in a parent controller

  - by meridimus

  I have made a ViewController in XCode for an iPhone project I'm working on, but I have a question about nested ViewControllers and what the best way to access a parents ViewController functions? Essentially, at the moment I have a SwitchViewController with MenuViewController (nested) and GameViewController (nested, which renders OpenGL ES). At the moment, I have animated view switching controlled in the SwitchViewController which works. But I want to call it after a player has selected the level from the MenuViewController and run the appropriate level in GameViewController. Not rocket science, I know. What's the best way to call parent functions?

• Why would a TableAdapter populate a DataSet with "1/1/2000" for an entire timestamp column?

  - by Rob

  I have a TableAdapter filling a DataSet, and for some reason every select query populates my timestamp column with the value 1/1/2000 for every selected row. I first verified that original values are intact on the DB side; for the most part, they are, although it seems a few rows lost their original timestamp because of update queries performed programmatically before the issue was discovered. The DataColumn type is DateType, while the database (Postgres) column type is timestamp. Up until recently, this was all playing very nicely. I noticed the issue in a bound DataGridView control, and verified that this is not related to data binding by utilizing the 'Preview Data' option in the VS DataSet Editor. Usually when I notice unexpected values popping up in my application it's related to a mis-configured property, type conflict, or another silly mistake I've made. So after checking properties and types, and even recreating the TableAdapter from scratch, to say I'm a little baffled is an understatement. Does anyone have any ideas of what I could do to fix the issue and/or diagnose the cause?

• Enable Datepicker only when first field has a value

  - by Syed Abdul Rahman

  Right now, the End Date selection is disabled. I want to only enable this when a Start Date is selected. if( $('#datepicker1').val().length === 0) { $('#datepicker2').datepicker("disable"); } else { $('#datepicker2').datepicker("enable"); } This clearly does not work. If I insert value = 'random date' into my first input field, it works fine. I'm not too sure on how do this. Clearly not as easy as I had hoped. My other problem, or hope, is to disable the dates including and before the first selection. You know, pick Start Date, and every date before and said date for the next picker would be disabled. But that is a whole other problem.
