• JME: How to get the complete screen in WHITE without buttons, etc etc

  - by Sepala

  Please have a look at the following code /* * To change this template, choose Tools | Templates * and open the template in the editor. */ import javax.microedition.midlet.*; import javax.microedition.lcdui.*; /** */ public class Midlet extends MIDlet{ private Form f; private Display d; private Command start,stop; private Thread t; public Midlet() { t = new Thread(new TurnLightOn()); } public void startApp() { f = new Form("Back Light On"); d = Display.getDisplay(this); d.setCurrent(f); start = new Command("Turn On",Command.OK,0); stop = new Command("Turn Off",Command.OK,1); f.addCommand(start); f.setCommandListener(new Action()); } public void pauseApp() { } public void destroyApp(boolean unconditional) { this.notifyDestroyed(); } private class Action implements CommandListener { public void commandAction(Command c, Displayable dis) { f.append("Light is Turnning On"); t.start(); } } private class ActionOff implements CommandListener { public void commandAction(Command c, Displayable dis) { } } private class TurnLightOn implements Runnable { public void run() { f.append("Working"); for(int i=0;i<100;i++) { try { d.flashBacklight(200); d.vibrate(200); Thread.sleep(1000); } catch (InterruptedException ex) { ex.printStackTrace(); } } } } } First, Please note I am a 100% newbie to Java Mobile. In here, I am making the light on and vibrate on when user click the button. However, I really wanted to create a SOS application which turn the whole screen into white, and go to black, like that, in the thread. I guess I didn't achieve that by this app because even the lights are on, the buttons are still there. I tried to turn the "Form" color to "white" but it seems like JME has no "Color" class! Please help!

• What is the purpose of the garbage (files) that Qt Creator auto-generates and how can I tame them?

  - by Venemo

  Hello Everyone, I'm fairly new to Qt, and I'm using the new Nokia Qt SDK beta and I'm working to develop a small application for my Nokia N900 in my free time. Fortunately, I was able to set up everything correctly, and also to run my app on the device. I've learned C++ in school, so I thought it won't be so difficult. I use Qt Creator as my IDE, because it doesn't work with Visual Studio. I also wish to port my app to Symbian, so I have run the emulator a few times, and I also compile for Windows to debug the most evil bugs. (The debugger doesn't work correctly on the device.) I come from a .NET background, so there are some things that I don't understand. When I hit the build button, Qt Creator generates a bunch of files to my project directory: moc_*.cpp files - I don't know their purpose. Could someone tell me? *.o files - I assume these are the object code *.rss files - I don't know their purpose, but they definitely don't have anything to do with RSS Makefile and Makefile.Debug - I have no idea AppName (without extension) - the executable for Maemo, and AppName.sis - the executable for Symbian, I guess? AppName.loc - I have no idea AppName_installer.pkg and AppName_template.pkg - I have no idea qrc_Resources.cpp - I guess this is for my Qt resources (where AppName is the name of the application in question) I noticed that these files can be safely deleted, Qt Creator simply regenerates them. The problem is that they pollute my source directory. Especially because I use version control, and if they can be regenerated, there is no point in uploading them to SVN. So, could someone please tell me what the exact purpose of these files is, and how can I ask Qt Creator to place them into another directory? Thank you in advance!

• how to create an function using jquery live? [Solved]

  - by Mahmoud

  Hey all i am trying to create a function that well keep the user in lightbox images while he adds to cart, for a demo you can visit secure.sabayafrah.com username: mahmud password: mahmud when you click at any image it well enlarge using lightbox v2, so when the user clicks at the image add, it well refresh the page, when i asked about it at jcart support form they informed me to use jquery live, but i dont know how to do it but as far as i tried this code which i used but still nothing is happening jQuery(function($) { $('#button') .livequery(eventType, function(event) { alert('clicked'); // to check if it works or not return false; }); }); i also used jQuery(function($) { $('input=[name=addto') .livequery(eventType, function(event) { alert('clicked'); // to check if it works or not return false; }); }); yet nothing worked for code to create those images http://pasite.org/code/572 Update 1: i have done this function adding(form){ $( "form.jcart" ).livequery('submit', function() {var b=$(this).find('input[name=<?php echo $jcart['item_id']?>]').val();var c=$(this).find('input[name=<?php echo $jcart['item_price']?>]').val();var d=$(this).find('input[name=<?php echo $jcart['item_name']?>]').val();var e=$(this).find('input[name=<?php echo $jcart['item_qty']?>]').val();var f=$(this).find('input[name=<?php echo $jcart['item_add']?>]').val();$.post('<?php echo $jcart['path'];?>jcart-relay.php',{"<?php echo $jcart['item_id']?>":b,"<?php echo $jcart['item_price']?>":c,"<?php echo $jcart['item_name']?>":d,"<?php echo $jcart['item_qty']?>":e,"<?php echo $jcart['item_add']?>":f} }); return false; } and it seems to add to jcart but yet it still refreshes

• Save a form in an XML file using Ajax and JSP

  - by novellino

  Hello, I want to create a simple form with a name and an email and save these data in an XML file. So far I found that using Ajax with jQuery is quite easy. So I used the usual code: //dataString have the values taken from the form var dataString = 'name='+ name + '&email=' + email; $.ajax({ type: "POST", url: "users.xml", data: dataString, dataType: "xml", success: function() { .... } }); If I understood well, in the url I should add the name of the XML file that will be created. When the user clicks a button I call the function with the Ajax request, and then I should call somewhere a function for generating the xml. I am using also two beans. One is for setting the elements of the user and the other is for saving the data in the XML. I am using the XStream library for the xml although I don't know if is the best solution. The problem now it that I can not connect all these together in order to save the data in the XML. Does anyone know what should I do? Thanks a lot!

• Add new row in a databound form with a Oracle Sequence as the primary key

  - by Ranhiru

  I am connecting C# with Oracle 11g. I have a DataTable which i fill using an Oracle Data Adapter. OracleDataAdapter da; DataTable dt = new DataTable(); da = new OracleDataAdapter("SELECT * FROM Author", con); da.Fill(dt); I have few text boxes that I have databound to various rows in the data table. txtAuthorID.DataBindings.Add("Text", dt, "AUTHORID"); txtFirstName.DataBindings.Add("Text", dt, "FIRSTNAME"); txtLastName.DataBindings.Add("Text", dt, "LASTNAME"); txtAddress.DataBindings.Add("Text", dt, "ADDRESS"); txtTelephone.DataBindings.Add("Text", dt, "TELEPHONE"); txtEmailAddress.DataBindings.Add("Text", dt, "EMAIL"); I also have a DataGridView below the Text Boxes, showing the contents of the DataTable. dgvAuthor.DataSource = dt; Now when I want to add a new row, i do bm.AddNew(); where bm is defined in Form_Load as BindingManagerBase bm; bm = this.BindingContext[dt]; And when the save button is clicked after all the information is entered and validated, i do this.BindingContext[dt].EndCurrentEdit(); try { da.Update(dt); } catch (Exception ex) { MessageBox.Show(ex.Message); } However the problem comes where when I usually enter a row to the database (using SQL Plus) , I use a my_pk_sequence.nextval for the primary key. But how do i specify that when i add a new row in this method? I catch this exception ORA-01400: cannot insert NULL into ("SYSMAN".AUTHOR.AUTHORID") which is obvious because nothing was specified for the primary key. How do get around this? Thanx a lot in advance :)

• CONFUSING : CGAffineTransform - rotation on uibutton resizes buttonimage ?! (iPad)

  - by Michael

  hi there, i've got a strange problem using uibuttons, type custom. i'm placing 4 of those buttons on a scrollview, rotating each button by a random angle using CGAffineTransform. now it seems, that the buttons itself change size depending on the angle of rotation. can't get this problem solved :( UIGraphicsBeginImageContext(tempCtxSize); [cookbookImage drawInRect:CGRectMake(imgOffsetX, imgOffsetY+frmOffsetY, cookbookImage.size.width, cookbookImage.size.height)]; [cookbookFrame drawInRect:CGRectMake(0.0f, frmOffsetY, cookbookFrame.size.width, cookbookFrame.size.height)]; UIImage *combinedImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); ... ... UIButton *cookbookViewButton = [UIButton buttonWithType:UIButtonTypeCustom]; [cookbookViewButton setFrame:CGRectMake(0.0f, 0.0f, combinedImage.size.width, combinedImage.size.height)]; [cookbookViewButton setBackgroundColor:[UIColor clearColor]]; [cookbookViewButton setBackgroundImage:combinedImage forState:UIControlStateNormal]; CGAffineTransform rotation = [cookbookViewButton transform]; rotation = CGAffineTransformRotate(rotation, angle); // some random angle [cookbookViewButton setTransform:rotation]; thx for your help in advance!

• MVC.NET custom validator is not working

  - by IvanMushketyk

  I want to write a custom validator for MVC.NET framework that checks if entered date is in the future. To do it, I wrote the following class: [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = true)] public sealed class InTheFutureAttribute : ValidationAttribute, IClientValidatable { private const string DefaultErrorMessage = "{0} should be date in the future"; public InTheFutureAttribute() : base(DefaultErrorMessage) { } public override string FormatErrorMessage(string name) { return string.Format(ErrorMessageString, name); } public override bool IsValid(object value) { DateTime time = (DateTime)value; if (time < DateTime.Now) { return false; } return true; } public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context) { var clientValidationRule = new ModelClientValidationRule() { ErrorMessage = FormatErrorMessage(metadata.GetDisplayName()), ValidationType = "wrongvalue" }; return new[] { clientValidationRule }; } } and added attribute to field that I want to check. On the View page I create input field in the following way: <div class="editor-label-search"> @Html.LabelFor(model => model.checkIn) </div> <div class="editor-field-search-date"> @Html.EditorFor(model => model.checkIn) <script type="text/javascript"> $(document).ready(function () { $('#checkIn').datepicker({ showOn: 'button', buttonImage: '/Content/images/calendar.gif', duration: 0, dateFormat: 'dd/mm/yy' }); }); </script> @Html.ValidationMessageFor(model => model.checkIn) </div> When I submit the form for the controller that requires model with checked attribute code in my validator is called and it returns false, but instead of displaying an error it just call my controller's action and send invalid model to it. Am I doing something wrong? How can I fix it? Thank you in advance.

• C#.NET DataGridView - update database

  - by Geo Ego

  I know this is a basic function of the DataGridView, but for some reason, I just can't get it to work. I just want the DataGridView on my Windows form to submit any changes made to it to the database when the user clicks the "Save" button. On form load, I populate the DataGridView and that's working fine. In my save function, I basically have the following (I've trimmed out some of the code around it to get to the point): using (SqlDataAdapter ruleTableDA = new SqlDataAdapter("SELECT rule.fldFluteType AS [Flute], rule.fldKnife AS [Knife], rule.fldScore AS [Score], rule.fldLowKnife AS [Low Knife], rule.fldMatrixScore AS [Matrix Score], rule.fldMatrix AS [Matrix] FROM dbo.tblRuleTypes rule WHERE rule.fldMachine_ID = '1003'", con)) { SqlCommandBuilder commandBuilder = new SqlCommandBuilder(ruleTableDA); DataTable dt = new DataTable(); dt = RuleTable.DataSource as DataTable; ruleTableDA.Fill(dt); ruleTableDA.Update(dt); } Okay, so I edited the code to do the following: build the commands, create a DataTable based on the DataGridView (RuleTable), fill the DataAdapter with the DataTable, and update the database. Now ruleTableDA.Update(dt) is throwing the exception "Concurrency violation: the UpdateCommand affected 0 of the expected 1 records." Thanks very much!

• Inactive area after device rotation

  - by Sébastien

  Hi all, I don't understand what's wrong in my very simple application with device rotation : I built my view with interface builder. (See screen capture here) I specified <key>UIInterfaceOrientation</key><string>UIInterfaceOrientationLandscapeRight</string> in my info.plist file. I had a (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {return YES;} in my root view controller. The area on the left (shown in red on the capture), around 20 pixel width, keeps inactive (nothing append if I hit a button in this area). In fact the full screen is active only in portrait mode, in landscape right mode there is this 20 pixels width inactive area, in landscape left mode this inactive area is on the right, in portrait upside down mode this area is on the bottom. I read lots of posts and documentation about UIView rotation, but I did not find anything to solve this problem (I tried to play with view.frame and view.bounds without any success). Anybody has an idea ? Thanks a lot. Regards. Sébastien.

• Adding SDK-specific frameworks to Xcode

  - by Haentz

  Hi, Xcode 3.2 kind of broke the build process of my iPhone app. I need to add a new framework to my project (MediaPlayer.framework). So I go into my Target settings and try to add it to the "Linked Libraris" by hitting the [+] button. In the list the MediaPlayer.framework is missing, as well as other frameworks, such as UIKit, CoreGraphic and others. Some frameworks are still there. I can add the frameworks by adding the SDK-specific ones (going into /Developer/Platforms/iPhoneOs.platform/...yadayadayada../frameworkd/) but then of course I can only compile for the iPhone platform and not for the simulator any more. So basically I wonder how I can get Xcode back to chose the appropriate framework, depending on platform and SDK version for me? Thanks and kind regards, Hans Schneider Edit: Things I tried: Setting the Base SDK to 3.0 (was still 2.2.1), reinstalling 3.0 iPhone and Simulator SDK from the "packages" directory of the Xcode 3.2 DMG. Didn't help. The frameworks still wont show up in the list... Edit 2: Ok, I now have the frameworks back in the list, I was previously in my AdHoc configuration. In Debug I have the frameworks back. But it still wont compile for the Simualtor (lots of Symbols(s) not found errors). Looks like the linker doesn't choose the correct libraries and always uses the iPhoneOs3.0 path for the frameworks.

• C# visually subclass datagridview control VS2005

  - by DRapp

  Maybe its something stupid, but I'm having a problem with a subclass of a DataGridView Control in VS2005 C#. I know I can subclass from almost anything by doing public class MyDataGridView : DataGridView {} no problem, and I put in some things / elements I want applicable globally. Now, I take this gridview and put into a custom user control that will contain other controls too. So I have something like created by the visual designer. I grab some buttons, label, and my derived "MyDataGridView" on it. public partial class MyCompoundDGVPlus : UserControl So, now, I can visually draw, move, change all sorts of settings as needed, no problem. Now, I want this "MyCompoundDGVPlus" class as the basis for other classes, of which I will manipulate settings specific, but want all to have the same look / feel, and otherwise similar flow, hence the derivations. I've even set the "modifiers" setting to public, so I SHOULD be able to modify any of the properties of the controls at any derived level. So, now, I create a new subclass of "MyFirstDetailedDGVPlus" derived from "MyCompoundDGVPlus". Ok visually, all the label, button, datagridview appear. However, now I want to specifically define the columns of the datagridview here in this class visually, but its locked. However, the LABEL on the form, I CAN get all the property settings.... What am I missing.

• Dragging a copy of all selected elements from a select box--possible?

  - by Sean

  I have a picklist web interface: a pair of select elements with a pair of buttons (a left-pointing arrow and a right-pointing arrow) between them. Users can move items between the two columns by, eg, selecting one of options in the left column and clicking on the right-pointing arrow. Now I have an enhancement request: someone wants to be able to drag-and-drop items between the two columns instead of clicking a button. The problem with my initial two-select-box setup is that as soon as I click one of the highlighted options to initiate a drag, all of the other selected options are deselected. Using jQuery, I've attached mousedown event handlers to both the select boxes and each individual option that just call preventDefault() on the event object, but this isn't sufficient. On Firefox 3 the clicked-on option loses focus immediately, but all other options are still deseleted, and on IE6 (which I regrettably still have to support) it makes no difference at all. So I thought I could maybe create a reasonable facsimile of a select box using list elements or divs or something. I can create something reasonable-looking that works on Firefox, but on IE6, if I shift-click on an element of my pseudo-select object (in order to select a range of options), IE selects all of the text between where I click and the last place I clicked. Again, I've attached preventDefault-ing mousedown, mouseup, and click handlers to all of the elements involved, but it doesn't help. I've even tried overlaying transparent divs over both my original select boxes and my pseudo-select objects, thinking to intercept mouse clicks and manage the selections manually, but I can't make it work on IE. If I use a select box, I can't prevent clicks from changing the selection, and if I use text that just looks like a select element, I can't prevent it from selecting a range of text on a shift-click. Is there some general solution, or am I just out of luck?

• Android app unexpectedly quitted when I closed the bluetooth serversocket or bluetooth socket

  - by Lewisou

  The android app quitted without any warning and error when bluetoothServersocket.close() called in the main thread while bluetoothServersocket.accept(); was blocked for incoming connections in another thread. Here is pieces of my code. public void run() { try { bluetoothServerSocket = BluetoothAdapter. getDefaultAdapter().listenUsingRfcommWithServiceRecord(LISTEN_NAME, LISTEN_UUID); /* the thread blocked here for incoming connections */ bluetoothSocket = bluetoothServerSocket.accept(); ... } catch(Exception e) {} finally { try {bluetoothServerSocket.close();} catch(Exception ex) {} try {bluetoothSocket.close();} catch(Exception ex) {} } } And in the activity. public void onStop () { try{thread.bluetoothSocket.close();} catch(Exception ex) {} try{thread.bluetoothServerSocket.close();} catch(Exception ex) {} super.onStop(); } When I clicked the back button. The activity closed but after about one second the app quitted without any warning. My android os version is 2.2. a HTC Desire device.

• GridView onTouch

  - by Jeff

  I am trying to set up a GridView of buttons that responds to onTouch. For example, if I swipe my finger across the screen horizontally, vertically or diagonally then I want the buttons which were touched to be selected. I tried setting OnTouchListener's for the buttons, but this didn't work, only the first button in the drag event received the onTouch events. Next I tried creating an OnTouchListener for the GridView and then using the X,Y coords to determine which buttons where touched. This doesn't seem to work either since the MOTION_DOWN events are only passed to the GridView's onTouch() if I start the drag on the very edge of the GridView. In fact if I drag my finger horizontally across the grid, the onTouch events aren't fired at all unless I start the drag at the edge of the GridView. Does anyone know of a better way to do this? Thanks in advance. gridview.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(@SuppressWarnings("unused") View view, MotionEvent event) { float X = event.getX(); float Y = event.getY(); switch (event.getAction()) { case MotionEvent.ACTION_DOWN: System.out.println("Down: " + X + "," + Y); break; case MotionEvent.ACTION_MOVE: System.out.println("Move: " + X + "," + Y); break; case MotionEvent.ACTION_UP: System.out.println("Up: " + X + "," + Y); break; } return true; } }

• Display gridview in new window

  - by Ricardo Deano

  Hello all. Just a bit of advice needed really in terms of how I should handle my current scenario: I have a web page that searches for products/category information the results of which are at present displayed in a gridview on the same page. However, said gridview is a bit of a beast and as such, I would like to have a page that the user searches for, a button is pressed and the subsequent gridview is displayed in a new window. Ultimately, I would like the user to be able to make multiple searches so that new windows can have multiple gridviews containing different data sets. My current thinking is to create session variables that can be pulled through onto 'the gridview page'. Having said that, I'm not sure that would work if multiple searches are created? I am also thinking I might be able to create said 'gridview window' using javascript but my concern here is the potential loss of functionality of the gridview i.e. paging, sorting, editing, etc. Does anyone have any thoughts or theories on this? What would be "best practise"? Any thoughts greatly appreciated and taken on board. PS: This is being developed in .net, using c# and LINQ. PPS: I'm a noob so be gentle!!

• Close application on error

  - by poke

  I’m currently writing an application for the Android platform that requires a mounted SD card (or ExternalStorage). I know that it might not be the best way to require something like that, but the application will work with quite a lot of data, and I don’t even want to think about storing that on the device’s storage. Anyway, to ensure that the application won’t run without the external storage, I do a quick check in the activity’s onCreate method. If the card is not mounted, I want to display an error message and then quit the application. My current approach looks like this: public void onCreate ( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); setContentView( R.layout.main ); try { // initialize data storage // will raise an exception if it fails, or the SD card is not mounted // ... } catch ( Exception e ) { AlertDialog.Builder builder = new AlertDialog.Builder( this ); builder .setMessage( "There was an error: " + e.getMessage() ) .setCancelable( false ) .setNeutralButton( "Ok.", new DialogInterface.OnClickListener() { public void onClick ( DialogInterface dialog, int which ) { MyApplication.this.finish(); } } ); AlertDialog error = builder.create(); error.show(); return; } // continue ... } When I run the application, and the exception gets raised (I raise it manually to check if everything works), the error message is displayed correctly. However when I press the button, the application closes and I get an Android error, that the application was closed unexpectedly (and I should force exit). I read some topics before on closing an application, and I know that it maybe shouldn’t happen like that. But how should I instead prevent the application from continuing to run? How do you close the application correctly when an error occurs?

• Android - ListActivity, add Header and Footer view

  - by Victor

  I'm using ListActivity, listview. listView = getListView(); just working perfectly. I added footer view as LayoutInflater inflater = getLayoutInflater(); listView.addFooterView( inflater.inflate( R.layout.footer, null ), null, false); and everything was shiny but ugly, so i wanted to add this footer view (which contains only 1 edittext and only 1 button ) to header of listView as LayoutInflater inflater = getLayoutInflater(); listView.addHeaderView( inflater.inflate( R.layout.footer, null ), null, false); and suddenly everything goes wrong, and i get RuntimeException immediately. Suspended(exception RuntimeException) ActivityThread.performLaunchActivity(ActivityThread$ActivityRecord, Intent) ActivityThread.handleLaunchActivity(ActivityThread$ActivityRecord, Intent) ActivityThread.access$2200(ActivityThread, Activity$ActiviyRecord, Intent), so on.. Why is it throws exception ? What is different between addFooterView and addHeaderView, and how can i add Header to ListActivity ? UPDATE So as you can read in comments, my logcat still doesn't work, but i just tried next at this moment: } catch(Exception e){ Writer result = new StringWriter(); PrintWriter printWriter = new PrintWriter(result); e.printStackTrace(printWriter); String error = result.toString(); } and afterward i put breakpoint, and i can read error in expressions section. it said : java.lang.IllegalStateException: Cannot add header view to list -- setAdapter has already been called. it was instructive for all of us. After change sort of commands, it works perferctly.

• Is there a good way of automatically generating javascript client code from server side python

  - by tat.wright

  I basically want to be able to: Write a few functions in python (with the minimum amount of extra meta data) Turn these functions into a web service (with the minimum of effort / boiler plate) Automatically generate some javascript functions / objects for rpc (this should prevent me from doing as many stupid things as possible like mistyping method names, forgetting the names of methods, passing the wrong number of arguments) Example python: def hello_world(): return "Hello world" javascript: ... <!-- This file is automatically generated (either dynamically or statically) --> <script src="http://myurl.com/webservice/client_side_javascript"> </script> ... <script> $('#button').click(function () { hello_world(function (data){ $('#label').text(data))) } </script> A bit of research has shown me some approaches that come close to this: Automatic generation of json-rpc services from functions with a little boiler plate code in python and then using jquery and json to do the calls (still easy to make mistakes with method names - still need to be aware of urls when calling, very irritating to write these calls yourself in the firebug shell) Using a library like soaplib to generate wsdl from python (by adding copious type information). And then somehow convert this into javascript (not sure if there is even a library to do this) But are there any approaches closer to what I want?

• wxpython GUI and multiprocessing - how to send data back from the long running process

  - by wxpydon

  Hello everyone, Trying to run a time consuming task from a wxpython GUI. The basic idea is to start the long time task from the GUI (pressing a button) and then, a static text on the dialog should be updated from it. First I tried some threading (http://wiki.wxpython.org/LongRunningTasks and many other resourses seen), and I want to show back the messages using Publisher.class. It didn't went so well, after a message or two, the GUI seems to frozen. Now I want to achieve that with multiprocessing. I have this method inside my 'GUI' class: def do_update(self, e): self.txt_updatemsg.SetLabel("Don't stop this \n") ... pub = Publisher() # i tried also calling directly from dbob object # Publisher() is a singleton so this must be useless? pub.subscribe(self.__update_txt_message, ('updatedlg', 'message')) dbob = dbutils.DBUtils() # DBUtils is the class with 'long time' tasks dbob.publisher = pub p = Process(target=self.do_update_process, args=(dbob,)) p.start() while p.is_alive: wx.Yield def do_update_process(self, dbob): dbob.do_update() __update_txt_message is a simple function what sets the static text on dialog.

• Can't get data with spaces into the database from Ajax POST request

  - by J Jones

  I have a real simple form with a textbox and a button, and my goal is to have an asynchronous request (jQuery: $.ajax) send the text to the server (PHP/mysql a la Joomla) so that it can be added to a database table. Here's the javascript that is sending the data from the client: var value= $('#myvalue').val(); $.ajax( { type: "POST", url: "/administrator/index.php", data: { option: "com_mycomponent", task: "enterValue", thevalue: value, format: "raw"}, dataType: "text", success: reportSavedValue } ); The problem arises when the user enters text with a space in it. The $_POST variable that I receive has all the spaces stripped out, so that if the user enters "This string has spaces", the server gets the value "Thisstringhasspaces". I have been googling around, and have found lots of references that I need to use encodeURIComponent. So I have tried it, but now the value that I get from $_POST is "This20string20has20spaces". So it appears to be encoding it the way I would expect, only to have the percent signs stripped instead of the spaces, and leaving the hex numbers. I'm really confused. It seems that this sort of question is asked and answered everywhere on the web, and everywhere encodeURIComponent is hailed as the silver bullet. But apparently I'm fighting a different breed of lycanthrope. Does anyone have any suggestions?

• How do I reset a form in an ajax callback?

  - by B.Gordon

  I am sending a form using simple ajax and returning the results in a div above the form. The problem is that after the form is submitted and validated, I display a thank you and want to reset the form so they don't just press the submit button again... Can't seem to find the right code to do this... <form id="myForm" target="sendemail.php" method="post"> <div id="results"></div> <input type="text" name="value1"> <input type="text" name="value2"> <input type="submit" name="submit"> </form> So, my sendemail.php validation errors and success messages appear in #results without problems. But... when I try to send back a javascript form reset command, it does not work. Naturally I cannot see it in the source code since it is an AJAX callback so I don't know if that is the issue or if I am just using the wrong syntax. echo "<p>Thank you. Your message has been accepted for delivery.</p>"; echo "<script type=\"text/javascript\">setTimeout('document.getElementById('myForm').reset();',1000);</script>"; Any ideas gurus?

• Only last row in method execute (Objective-C)

  - by Emil

  First I want to apologize for my lack of knowledge in programming in general. I am in the way of learning and have discovered that this site is a huge compliment for me of doing so. I have created a program with three UITextField(thePlace,theVerb,theOutput) and two UITextView where one of the textviews(theOutput) take the text from the other textview(theTemplate) and replaces some strings with the text entered in the textfields. When I click a button it triggers the method createStory that is listed below. This works fine with one exception. The text in the output only changes the string 'number' to the text in the textfield. However if I change the order in the method to replace 'place','number','verb' only the verb is changed, not the number. Im sure this is some sort of easy fix but I can't find it. Can some of you help me with my troubleshooting? - (IBAction)createStory:(id)sender { theOutput.text=[theTemplate.text stringByReplacingOccurrencesOfString:@"<place>" withString:thePlace.text]; theOutput.text=[theTemplate.text stringByReplacingOccurrencesOfString:@"<verb>" withString:theVerb.text]; theOutput.text=[theTemplate.text stringByReplacingOccurrencesOfString:@"<number>" withString:theNumber.text]; } Many thanks // Emil
