How to manage a MotionEvent going from one View to another?

- by Darren

I have a SurfaceView that takes up part of the screen, and some buttons along the bottom. When a button is pressed and the user drags, I want to be able to drag a picture (based on the button) onto the SurfaceView and have it drawn there. I want to be able to use clickListeners and the like, and not just have a giant SurfaceView with me writing code to detect where the user pressed and if it's a button, etc. I have somewhat of a solution, but it seems a bit of a hack to me. What is the best way to accomplish this using the framework intelligently? Part of my XML: <RelativeLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/background">  <RelativeLayout android:id="@+id/bottom_bar" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="40dip" android:layout_alignParentBottom="true" android:background="@null"> <ImageButton android:id="@+id/btn_1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:background="@null" android:src="@drawable/btn_1"> </ImageButton>  </RelativeLayout>  <FrameLayout android:layout_width="fill_parent" android:layout_height="0px" android:layout_weight="1" android:layout_above="@id/bottom_bar"> <com.project.question.MySurfaceView android:id="@+id/my_view" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </FrameLayout> And the relevant Java code in MySurfaceView, which extends SurfaceView. mTouchX and Y are used in the onDraw method to draw the image: @Override public boolean onTouchEvent(MotionEvent event){ mTouchX = (int) event.getX(); mTouchY = (int) event.getY(); return true; } public void onButtonTouchEvent(MotionEvent event){ event.setLocation(event.getX(), event.getY() + mScreenHeight); onTouchEvent(event); } Finally, the activity: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.my_surface); mView = (MySurfaceView) findViewById(R.id.my_view); mSurfaceHeight = mView.getHeight(); mBtn = (ImageButton) findViewById(R.id.btn_1); mBtn.setOnTouchListener(mTouchListener); } OnTouchListener mTouchListener = new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { int [] location = new int[2]; v.getLocationOnScreen(location); event.setLocation(event.getX() + location[0], event.getY()); mView.onButtonTouchEvent(event); return true; } }; Strangely, one has to add to the x-coordinate in the activity, then add to the y coordinate in the View. Otherwise, it doesn't show up in the correct position. If you add nothing, something drawn using mTouchX and mTouchY will show up in the upper left corner of the SurfaceView. Any direction would be greatly appreciated. If I'm going about this completely the wrong way, that would be good information too.

receiving error #1009 in flash cs4 actionscript3

- by Leah

I'm having a weird issue where my buttons will work initially and direct me to an appropriate page, but when i go back to that page and try to use the buttons the roll-overs work but none of the buttons direct to a different page. This is the actionscript on the initial page with the buttons. If I choose any of these buttons they work. For example the profile_btn will take me to the go_to_page" stop(); import flash.events.MouseEvent; //button instancese listed below profile_btn.addEventListener(MouseEvent.CLICK, aClick); function aClick(event:MouseEvent):void{ gotoAndPlay("go_to_page"); } color_btn.addEventListener(MouseEvent.CLICK, cClick); function cClick(event:MouseEvent):void{ gotoAndPlay("color_page"); } drawing_btn.addEventListener(MouseEvent.CLICK, dClick); function dClick(event:MouseEvent):void{ gotoAndPlay("drawing_page"); } letsgo_btn.addEventListener(MouseEvent.CLICK, fClick); function fClick(event:MouseEvent):void{ gotoAndPlay("home_page"); } //go to flash fish animation digital_btn.addEventListener(MouseEvent.CLICK,onMouseClick2); function onMouseClick2(e:MouseEvent):void { var request:URLRequest=new URLRequest("aquarium2.swf"); navigateToURL(request,"blank");} //go to resume document resume_btn.addEventListener(MouseEvent.CLICK,onMouseClick3); function onMouseClick3(e:MouseEvent):void { var request:URLRequest=new URLRequest("LeahHonseyResume.pdf"); navigateToURL(request,"blank"); once at the go_to_page, it plays through a motion tween and ends up at the profile_page. from this page, there is a home_btn. Here is the actionscript for the profile_page. stop(); home_btn.addEventListener(MouseEvent.CLICK, gClick); function gClick(event:MouseEvent):void{ gotoAndPlay("return_frame"); } But when I click on the home_btn I get an output: TypeError: Error #1009: Cannot access a property or method of a null object reference. at flash7_fla::MainTimeline/frame38() It does take me to the correct page, but none of the button then on this page are working. the actionscript for the return_frame page is: stop(); import flash.events.MouseEvent; //button instances listed below profile_btn.addEventListener(MouseEvent.CLICK, hClick); function hClick(event:MouseEvent):void{ gotoAndPlay("profile_page"); } color_btn.addEventListener(MouseEvent.CLICK, iClick); function iClick(event:MouseEvent):void{ gotoAndPlay("color_page"); } drawing_btn.addEventListener(MouseEvent.CLICK, jClick); function jClick(event:MouseEvent):void{ gotoAndPlay("drawing_page"); } letsgo_btn.addEventListener(MouseEvent.CLICK, kClick); function kClick(event:MouseEvent):void{ gotoAndPlay("home_page"); } //go to flash fish animation digital_btn.addEventListener(MouseEvent.CLICK,onMouseClick4); function onMouseClick4(e:MouseEvent):void { var request:URLRequest=new URLRequest("aquarium2.swf"); navigateToURL(request,"blank");} //go to resume document resume_btn.addEventListener(MouseEvent.CLICK,onMouseClick5); function onMouseClick5(e:MouseEvent):void { var request:URLRequest=new URLRequest("LeahHonseyResume.pdf"); navigateToURL(request,"blank");} Can anyone help me figure out why this script is not working? Thank you. I am a beginner flash user, and am trying to build my portfolio site for a homework assignment on Monday. Leah

How do I record video to a local disk in AIR?

- by Jim OHalloran

I'm trying to record a webcam's video and audio to a FLV file stored on the users local hard disk. I have a version of this code working which uses NetConnection and NetStream to stream the video over a network to a FMS (Red5) server, but I'd like to be able to store the video locally for low bandwidth/flaky network situations. I'm using FLex 3.2 and AIR 1.5, so I don't believe there should be any sandbox restrictions which prevent this from occurring. Things I've seen: FileStream - Allows reading.writing local files but no .attachCamera and .attachAudio methids for creating a FLV. flvrecorder - Produces screen grabs from the web cam and creates it's own flv file. Doesn't support Audio. License prohibits commercial use. SimpleFLVWriter.as - Similar to flvrecorder without the wierd license. Doesn't support audio. This stackoverflow post - Which demonstrates the playback of a video from local disk using a NetConnection/NetStream. Given that I have a version already which uses NetStream to stream to the server I thought the last was most promising and went ahead and put together this demo application. The code compiles and runs without errors, but I don't have a FLV file on disk which the stop button is clicked. - <mx:Script> <![CDATA[ private var _diskStream:NetStream; private var _diskConn:NetConnection; private var _camera:Camera; private var _mic:Microphone; public function cmdStart_Click():void { _camera = Camera.getCamera(); _camera.setQuality(144000, 85); _camera.setMode(320, 240, 15); _camera.setKeyFrameInterval(60); _mic = Microphone.getMicrophone(); videoDisplay.attachCamera(_camera); _diskConn = new NetConnection(); _diskConn.connect(null); _diskStream = new NetStream(_diskConn); _diskStream.client = this; _diskStream.attachCamera(_camera); _diskStream.attachAudio(_mic); _diskStream.publish("file://c:/test.flv", "record"); } public function cmdStop_Click() { _diskStream.close(); videoDisplay.close(); } ]]> </mx:Script> <mx:VideoDisplay x="10" y="10" width="320" height="240" id="videoDisplay" /> <mx:Button x="10" y="258" label="Start" click="cmdStart_Click()" id="cmdStart"/> <mx:Button x="73" y="258" label="Stop" id="cmdStop" click="cmdStop_Click()"/> </mx:WindowedApplication> It seems to me that there's either something wrong with the above code which is preventing it from working, or NetStream just can't be abused in this wany to record video. What I'd like to know is, a) What (if anything) is wrong with the code above? b) If NetStream doesn't support recording to disk, are there any other alternatives which capture Audio AND Video to a file on the users local hard disk? Thanks in advance!

How do I call up values in PHP for user input in forms (radio buttons and selects)

- by Derek

Ok so my admin sets to edit a book which was created. I know how to bring in the values that were initially entered via a simple text field like 'bookname'. On the edit book page the book name field stores the currently assigned 'bookname' in the field (which is what I want! :) ) However I have other field types like selects and radio button entries...I'm having trouble calling in the already set value when the book was created. For example, there is a 'booklevel' field, which I have set as radio button entries as; Hard, Normal, and Easy. When the user goes to edit the book, I'm not too sure on how to have the current value drawn up (its stored as text) and the radio button being checked. I.e. 'Normal' is checked if this is what was set when the book was created. So far I have this as the code for the adding book level: <label>Book Level:</label> <label for="booklevel1" class="radio">Hard <input type="radio" name="booklevel" id="booklevel1" value="<?php echo 'Hard'; if (isset($_POST['booklevel'])); ?>"></label> <label for="booklevel2" class="radio">Medium<input type="radio" name="booklevel" id="booklevel2" value="<?php echo 'Normal'; if (isset($_POST['booklevel'])); ?>"></label> <label for="booklevel" class="radio">Low<input type="radio" name="booklevel" id="booklevel3" value="<?php echo 'Easy'; if (isset($_POST['booklevel'])); ?>"></label> This all works fine by the way when the user adds the book... But does anyone know how in my update book form, I can draw the value of what level has been set, and have the box checked?? To draw up the values in the text fields, I'm simply using: <?php echo $row['bookname']?> I also noticed a small issue when I call up the values for my Select options. I have the drop down select field display the currently set user (to read the book!), however, the drop down menu again displays the user in the list available options to select - basically meaning 2 of the same names appear in the list! Is there a way to eliminate the value of the SELECTED option? So far my setup for this is like: <select name="user_id" id="user_id"> <option value="<?php echo $row['user_id']?>" SELECTED><?php echo $row['fullname']?></option> <?php while($row = mysql_fetch_array($result)) { ?> <option value="<?php echo $row['user_id']?>"><?php echo $row['name']?></option> <?php } ?> </select> If anyone can help me I'll be very greatful. Sorry for the incredibly long question!! :)

How do I make this scroll layout work?

- by JuiCe

I am currently trying to get my UI to have a Title Bar, a bottom Button bar, with a ScrollView in between. I can get bits and pieces of it to work, but once I get a different piece working, the old part goes back to not showing up. Here is a picture of my UI on the left, with what I want it to look like on the right...(sorry for the sloppiness, I edited it in MS Paint :P ) To sum it up, I want the Version and Type fields to be moved with room for the other TextViews in the XML file, and I want both buttons to appear on the bottom bar. EDIT : The buttons on the bottom should be equal in size, I'm not too talented in making boxes in MS Paint EDIT 2 : Sorry....here is my XML file <?xml version="1.0" encoding="UTF-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:weightSum="1.0" > <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" android:text="SN : " /> <TextView android:id="@+id/serialNumberView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" android:text="Ver : " /> <TextView android:id="@+id/versionView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" android:text="Type : " /> <TextView android:id="@+id/typeView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal" /> </LinearLayout> <ScrollView android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" > <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" android:layout_weight="1"> <CheckBox android:id="@+id/floatCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Float" /> <CheckBox android:id="@+id/tripCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Trip" /> <CheckBox android:id="@+id/closeCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Close" /> <CheckBox android:id="@+id/blockedCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Blocked" /> <CheckBox android:id="@+id/hardTripCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Hard Trip" /> <CheckBox android:id="@+id/phaseAngleCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Phase angle wrong for closing" /> <CheckBox android:id="@+id/diffVoltsCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Differential volts too low" /> <CheckBox android:id="@+id/networkVoltsCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Network volts too low to close" /> <CheckBox android:id="@+id/usingDefaultsCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Using Defaults( Reprogram )" /> <CheckBox android:id="@+id/relaxedCloseActiveCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Relaxed Close Active" /> <CheckBox android:id="@+id/commBoardDetectedCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Comm Board Detected" /> <CheckBox android:id="@+id/antiPumpBlock" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Anti-Pump Block" /> <CheckBox android:id="@+id/motorCutoffCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Motor Cutoff Inhibit" /> <CheckBox android:id="@+id/phaseRotationCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Phase Rotation Wrong" /> <CheckBox android:id="@+id/usingDefaultDNPCheck" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text= "Using Default DNP Profile" /> </LinearLayout> </ScrollView> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:layout_weight="1" > <Button android:id="@+id/button3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="Back" /> <Button android:id="@+id/button3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="Read" /> </LinearLayout> </LinearLayout>

- by I Like PHP

i have two select box, now what i want is i want to move option from one select box to another via a button below is my code: php <table> <tr> <td> <select size="5" id="suppliedMovies" name="suppliedMovies"> <option selected="selected" value="">Select Movie</option> <option value="1">sholay</option> <option value="3">Jism</option> <option value="4">Rog</option> <option value="5">Zeher</option> <option value="6">Awarpan</option> <option value="7">Paap</option> <option value="8">paanch<option> <option value="9">no entry</option> </select> </td> <td> <input type="button" id="toRight" value=">>"><br> <input type="button" id="toLeft" value="<<"> </td> <td> <select size="5" id="accquiredMovies" name="accquiredMovies"> <option> No item right now</option> </select> </td> </tr> </table> Jquery jQuery(document).ready( function() { function displayVals() { var myValues = jQuery("#suppliedMovies").val(); return myValues; } jQuery('#toRight').click(function(){ var x=displayVals(); console.log(x); var txt=jQuery("#suppliedMovies option[value='"+x+"']").text(); console.log(txt); if(x!=''){ jQuery('#accquiredMovies').append("<option value='"+x+"' >"+txt+"</option>"); } }); }); i m using above jQuery, that is working fine but, i want that when one item is copy from one select box to another select box, then that item should be disable(or probably delete) from first select box (to prevent duplicate entry). i also want to move item from right to left select box please suggest me optimized jQuery .

CrossPage PostBack in series of web pages

- by Vishnu Reddy

I had a requirement to pass data between pages in my application. I have a Page A where user will input some data and on submit User will be redirected to Page B where again user will enter some more data and on submitting user will be show a confirmation in Page C after doing some calculations and data saving. Following is the idea I was trying to use: PageA.aspx: <form id="frmPageA" runat="server"> <p>Name: <asp:TextBox ID="txtName" runat="server"></asp:TextBox></p> <p>Age: <asp:TextBox ID="txtAge" runat="server"></asp:TextBox></p> <p><asp:Button ID="btnPostToPageB" runat="server" Text="Post To PageB" PostBackUrl="~/PageB.aspx" /></p> </form> In Page A Codebehind file I am creating following public properties of the inputs to access in Page B: public string Name { get { return txtName.Text.ToString(); } } public int Age { get { return Convert.ToInt32(txtAge.Text); } } In PageB.aspx: using previouspage directive to access page A public properties <%@ PreviousPageType VirtualPath="~/PageA.aspx" % <form id="frmPageB" runat="server"> <asp:HiddenField ID="hfName" runat="server" /> <asp:HiddenField ID="hfAge" runat="server" /> <p><asp:RadioButtonList ID="rblGender" runat="server" TextAlign="Right" RepeatDirection="Horizontal"> <asp:ListItem Value="Female">Female</asp:ListItem> <asp:ListItem Value="Male">Male</asp:ListItem> </asp:RadioButtonList></p> <p><asp:Button ID="btnPostToPageC" runat="server" Text="Post To PageC" PostBackUrl="~/PageC.aspx" /></p> </form> In Page B Codebehind file I am creating following public properties for the inputs to access in Page C: public RadioButtonList Gender { get { return rblGender; } } public string Name { get { return _name; } } public int Age { get { return _age; } } //checking if data is posted from Page A otherwise redirecting User to Page A protected void Page_Load(object sender, EventArgs e) { if (PreviousPage != null && PreviousPage.IsCrossPagePostBack && PreviousPage.IsValid) { hfName.Value = PreviousPage.Name; hfAge.Value = PreviousPage.Age.ToString(); } else Response.Redirect("PageA.aspx"); }` in PageC.aspx: using previouspage directive to access page A public properties <%@ PreviousPageType VirtualPath="~/PageB.aspx" % <form id="frmPageC" runat="server"> <p>Name: <asp:Label ID="lblName" runat="server"></asp:Label></p> <p>Age: <asp:Label ID="lblAge" runat="server"></asp:Label></p> <p>Gender: <asp:Label ID="lblGender" runat="server"></asp:Label></p> <p><asp:Button ID="btnBack" runat="server" Text="Back" PostBackUrl="~/PageA.aspx" /></p> </form> Page C code behind file: if (PreviousPage != null && PreviousPage.IsCrossPagePostBack && PreviousPage.IsValid) { lblName.Text = PreviousPage.Name.ToString(); lblAge.Text = PreviousPage.Age.ToString(); lblGender.Text = PreviousPage.Gender.SelectedValue.ToString(); } else Response.Redirect("PageA.aspx");

How to structure a Kohana MVC application with dynamically added fields and provide validation and f

- by Matt H

I've got a bit of a problem. I have a Kohana application that has dynamically added fields. The fields that are added are called DISA numbers. In the model I look these up and the result is returned as an array. I encode the array into a JSON string and use JQuery to populate them The View knows the length of the array and so creates as many DISA elements as required before display. See the code below for a summary of how that works. What I'm finding is that this is starting to get difficult to manage. The code is becoming messy. Error handling of this type of dynamic content is ending up being spread all over the place. Not only that, it doesn't work how I want. What you see here is just a small snippet of code. For error handling I am using the validation library. I started by using add_rules on all the fields that come back in the post. As they are always phone numbers I set a required rule (when it's there) and a digit rule on the validation-as_array() keys. That works. The difficulty is actually giving it back to the view. i.e. dynamically added javascript field. Submits back to form. Save contents into a session. View has to load up fields from database + those from the previous post and signal the fields that have problems. It's all quite messy and I'm getting this code spread through both the view the controller and the model. So my question is. Have you done this before in Kohana and how have you handled it? There must be an easier way right? Code snippet. -- edit.php -- public function phone($id){ ... $this->template->content->disa_numbers = $phones->fetch_disa_numbers($this->account, $id); ... } -- phones.php -- public function fetch_disa_numbers($account, $id) { $query = $this->db->query("SELECT id, cid_in FROM disa WHERE owner_ext=?", array($id)); if (!$query){ return ''; } return $query; } -- edit_phones.php --- <script type="text/javascript"> var disaId = 1; function delDisaNumber(element){ /* Put 'X_' on the front of the element name to mark this for deletion */ $(element).prev().attr('name', 'X_'+$(element).prev().attr('name')); $(element).parent().hide(); } function addDisaNumber(){ /* input name is prepended with 'N_' which means new */ $("#disa_numbers").append("<li><input name='N_disa"+disaId+"' id='disa'"+ "type='text'/><a class='hide' onClick='delDisaNumber(this)'></a></li>"); disaId++; } </script> ... <php echo form::open("edit/saveDisaNumbers/".$phone, array("class"=>"section", "id"=>"disa_form")); echo form::open_fieldset(array("class"=>"balanced-grid")); ?> <ul class="fields" id="disa_numbers"> <?php $disaId = 1; foreach ( $disa_numbers as $disa_number ){ echo '<li>'; echo form::input('disa'.$disaId, $disa_number->cid_in); echo'<a class="hide" onclick="delDisaNumber(this)"></a>'; echo "</li>"; $disaId++; } ?> </ul> <button type="button"onclick="addDisaNumber()"><a class="add"></a>Add number</button> <?php echo form::submit('submit', 'Save'); echo form::close(); ?>

Unable to connect SQL Server instance from Visual Studio 2008 Version 9.0

- by salvationishere

I am getting the below error from VS on an 32-bit XP Professional server even though I set Tools-Options-Database Tools-Data Connections to "SIDEKICK", which is the name of my computer. In other words SIDEKICK should default to the full SQLSERVER. In other words, I want VS to use SQLSERVER instead of SQLSERVER EXPRESS. And I can clearly see my database both from VS in the Server Explorer and also in SSMS 2008. Furthermore, I can view the tables of this database in Server Explorer from VS.

Why isn't this javascript with else if working?

- by Uni

I'm sorry I can't be any more specific - I have no idea where the problem is. I'm a total beginner, and I've added everything I know to add to the coding, but nothing happens when I push the button. I don't know at this point if it's an error in the coding, or a syntax error that makes it not work. Basically I am trying to get this function "Rip It" to go through the list of Dewey decimal numbers, change some of them, and return the new number and a message saying it's been changed. There is also one labeled "no number" that has to return an error (not necessarily an alert box, a message in the same space is okay.) I am a total beginner and not particularly good at this stuff, so please be gentle! Many thanks! <!DOCTYPE html> <html> <head> <script type="text/javascript"> function RipIt() { for (var i = l; i <=10 i=i+l) { var dewey=document.getElementById(i); dewey=parseFloat(dewey); if (dewey >= 100 && 200 >= dewey) { document.getElementById('dewey'+ 100) } else if (dewey >= 400 && 500 >= dewey) { document.getElementById('dewey'+ 200) } else if (dewey >= 850 && 900 >= dewey) { document.getElementById('dewey'-100) } else if (dewey >= 600 && 650 >= dewey) { document.getElementById('dewey'+17) } } } </script> </head> <body> <h4>Records to Change</h4> <ul id="myList"> <li id ="1">101.33</li> <li id = "2">600.01</li> <li id = "3">001.11</li> <li id = "4">050.02</li> <li id = "5">199.52</li> <li id = "6">400.27</li> <li id = "7">401.73</li> <li id = "8">404.98</li> <li id = "9">no number</li> <li id = "10">850.68</li> <li id = "11">853.88</li> <li id = "12">407.8</li> <li id = "13">878.22</li> <li id = "14">175.93</li> <li id = "15">175.9</li> <li id = "16">176.11</li> <li id = "17">190.97</li> <li id = "18">90.01</li> <li id = "19">191.001</li> <li id = "20">600.95</li> <li id = "21">602.81</li> <li id = "22">604.14</li> <li id = "23">701.31</li> <li id = "24">606.44</li> <li id = "25">141.77</li> </ul> <b> </b> <input type="button" value="Click To Run" onclick="RipIt()">  </body> </html>

pass data from popup to parent

- by user522962

I have a parent w/ a popup child. When parent loads, I have to call a function within the popup without showing the popup (thus, I load "pupLove" but don't include it in layout)....I then pass this data to the parent. When the user manually clicks another button to open the popup, the same function is called & data passed to the parent. However, I am not able to pass dg.length to the parent. I believe the root problem is that I am loading "pupLove" & thus the parents are getting confused.....I'm guessing if I get rid of "pupLove" I can pass the data correctly but will need to call the child's function at creationComplete of the parent....how do I do that? Here's my parent: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" backgroundColor="green" width="50%" height="100%" xmlns:local="*" > <fx:Script> <![CDATA[ import pup; import mx.managers.PopUpManager; public function showPup(evt:MouseEvent):void { var ttlWndw:pup = PopUpManager.createPopUp(this, pup, true) as pup; PopUpManager.centerPopUp(ttlWndw); } ]]> </fx:Script> <mx:VBox> <local:pup id="pupLove" visible="false" includeInLayout="false" /> <s:Button click="showPup(event);" label="launch Pup" /> <mx:Text id="Ptest" color="black" text="from Parent:{pupLove.dg.length}" /> </mx:VBox> </s:Application> And a popup child called 'pup.mxml': <?xml version="1.0" encoding="utf-8"?> <s:Group xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300"> <fx:Script> <![CDATA[ public function init():void{ // send php call } import mx.events.CloseEvent; import mx.managers.PopUpManager; private function removePup(evt:Event):void { PopUpManager.removePopUp(this); } ]]> </fx:Script> <fx:Declarations> <s:ArrayCollection id="dg"> </s:ArrayCollection> </fx:Declarations> <s:TitleWindow width="100%" height="100%" close="removePup(event)"> <mx:VBox> <mx:Text id="test" color="red" text="from Child:{dg.length}" /> <s:Button label="add Items" click="dg.addItem({id:'cat'})" /> </mx:VBox> </s:TitleWindow> </s:Group> UPDATE: I guess my question can be more easily stated as: "is there a way to call a child's function from the parent without actually loading the child?"

wxPthon problems with Wrapping StaticText

- by Scott B

Hello. I am having an issue with wxPython. A simplified version of the code is posted below (white space, comments, etc removed to reduce size - but the general format to my program is kept roughly the same). When I run the script, the static text correctly wraps as it should, but the other items in the panel do not move down (they act as if the statictext is only one line and thus not everything is visible). If I manually resize the window/frame, even just a tiny amount, everything gets corrected and displays as it is should. I took screen shots to show this behavior, but I just created this account and thus don't have the required 10 reputation points to be allowed to post pictures. Why does it not display correctly to begin with? I've tried all sorts of combination's of GetParent().Refresh() or Update() and GetTopLevelParent().Update() or Refresh(). I've tried everything I can think of but cannot get it to display correctly without manually resizing the frame/window. Once re-sized, it works exactly as I want it to. Information: Windows XP Python 2.5.2 wxPython 2.8.11.0 (msw-unicode) Any suggestions? Thanks!

How to schedule dynamic function with cron job?

- by iBrazilian2

I want to know how I can schedule a dynamic(auto populated data) function to auto run everyday at saved time? Let's say I have a form that once the button is clicked it sends the data to the function, which the posts the data. I simply want to automate that so that I don't have to press the button. <ul> <?php foreach($Class->retrieveData as $data) { <form method="post" action=""> <li> <input type="hidden" name="name">'.$data['name'].'<br/> <input type="hidden" name="description">'.$data['description'].'<br/> <input type="submit" name="post_data" value="Post"> </li> </form> } ?> </ul> Now, the form will pass the data to the function. if(isset($_POST['post_data'])) // if post_data button is clicked then it runs myFunction() { myFunction(); } myFunction() { $name = $_POST['name']; $description = $_POST['description']; } I tried doing the following but the problem is that Cron Job can only run the whole .php file, and I am retrieving the saved time to run from MySQL. foreach($Class->getTime() as $timeData) { $timeHour = $timeData['timeHour']; $timeMinute = $timeData['timeMinute']; $hourMin = date('H:i'); $timeData = ''.$timeHour.':'.$timeMinute.''; if($hourMin == $timeData) { run myFunction. } } $hourMin is the current hour:minute which is being matched against a saved time to auto run from Mysql. So if $hourMin == $timeData then the function will run. How can I run Cron Job to auto run myFunction() if the $hourMin equals $timeData? So... List 1 = is to be runned at 10am List 2 = is to be runned at 12pm List 3 = is to be runned at 2pm The 10am, 12pm, 2pm is the $timeHour and $timeMinute that is retrieved from MySQL but based on each list id's. EDIT @randomSeed, 1) I can schedule cron jobs. 2) $name and $description will all be arrays, so the following is what I am trying to accomplish. $name = array( 'Jon', 'Steven', 'Carter' ); $description = array( 'Jon is a great person.', 'Steven has an outgoing character.', 'Carter is a horrible person.' ); I want to parse the first arrays from both $name and $description if the scheduled time is correct. In database I have the following postDataTime table +----+---------+----------+------------+--------+ | iD | timeDay | timeHour | timeMinute | postiD | +--------------------------------------+--------+ | 1 | * | 9 | 0 | 21 | |----|---------|----------|------------|--------| | 2 | * | 10 | 30 | 22 | |----|---------|----------|------------|--------| | 3 | * | 11 | 0 | 23 | +----|---------+----------+------------+--------+ iD = auto incremented on upload. timeDay = * is everyday (cron job style) timeHour = Hour of the day to run the script timeMinute = minute of the hour to run script postiD = this is the id of the post that is located in another table (n+1 relationship) If it's difficult to understand.. if(time() == 10:30(time from MySQL postiD = 22)) { // run myFunction with the data that is retrieved for that time ex: $postiD = '22'; $name = 'Steven'; $description = 'Steven has an outgoing character.'; // the above is what will be in the $_POST from the form and will be // sent to the myFunction() } I simply want to schedule everything according to the time that is saved to MySQL as I showed at the very top(postDataTime table). (I'd show what I have tried, but I have searched for countless hours for an example of what I am trying to accomplish but I cannot find anything and what I tried doesn't work.). I thought I could use the exec() function but from what it seems that does not allow me to run functions, otherwise I would do the following.. $time = '10:30'; if($time == time()) { exec(myFunction()); }

Hi, I have retrieved data from Json URL and displayed it in a table view. I have also inlcuced a button in table view. On clicking the button the data must be transferred to a another table view.

how to make css submenu stay put when subpage has been selected.

- by Ronedog

I have a css horizontal menu with a menu / submenu display working on the hover, but I would also like to make the submenu options stay put when I've selected that page. The code below shows the submenu on hover, but goes away on mouse out. I'm having some difficulty figuring out how to make my code work to keep the submenu items staying put? How can I do this? Thanks for your help. Here's the HTML: <ul id="menu_nav"> <li> <a href="#" class="button">Home</a> <span> <a href="#">Home Link1</a> <a href="#">Home Link2</a> <a href="#">Home Link3</a> </span> </li> <li> <a href="#" class="button">About Us</a> <span> <a href="#">About Link1</a> <a href="#">About Link2</a> <a href="#">About Link3</a> </span> </li> </ul> Here's the CSS ul#menu_nav { position:relative; float:left; width:790px; padding:0; margin:0; list-style-type:none; background-color:#000099; } ul#menu_nav li {float: left; margin: 0; padding: 0; border-right: 1px solid #555;} ul#menu_nav li a.button { float:left; text-decoration:none; color:white; background-color:#000099; padding:0.2em 0.6em; border-right:1px solid #CCCCCC; font-family: Tahoma; font-size: 11px; font-style: normal; font-weight: bold; position: relative; height: 21px; line-height:1.85em; } ul#menu_nav li a:hover { background-color:#F7F7F7; color:#000099; border-top:1px solid #CCCCCC; } ul#menu_nav li span{ float: left; padding: 15px 0; position: absolute; left: 0; top:25px; display: none; /*--Hide by default--*/ width: 790px; background: #F7F7F7; color: #fff; } ul#menu_nav li:hover span { display: block; } /*--Show subnav on hover--*/ ul#menu_nav li span a { display: inline; } /*--Since we declared a link style on the parent list link, we will correct it back to its original state--*/ ul#menu_nav li span a:hover {text-decoration: underline;} Heres the jquery: $("ul#menu_nav li").hover(function() { //Hover over event on list item $(this).css({ 'background' : '#1376c9'}); //Add background color and image on hovered list item $(this).find("span").show(); //Show the subnav } , function() { //on hover out... $(this).css({ 'background' : 'none'}); //Ditch the background $(this).find("span").hide(); //Hide the subnav });

Android refresh StateListDrawable problem

- by Max

Hi all, I have a strange problem with StateListDrawable or maybe (probably) I'm missing something. I created a test application for it and the same problem occurs. So, this is my StateListDrawable resourse in file test_selection.xml <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_selected="true"> <shape android:shape="rectangle" android:background="#ff0000"> <corners android:radius="10dp" /> <gradient android:startColor="#ff5555" android:endColor="#ff5555" android:angle="0" /> </shape> </item> <item android:state_selected="false"> <shape android:shape="rectangle" android:background="#eeeeee"> <corners android:radius="10dp" /> <gradient android:startColor="#eeeeee" android:endColor="#eeeeee" android:angle="0" /> </shape> </item> </selector> It's a very simple selector that draw a red color for selected state and a white rect for the unselected one. My main.xml template is very simple. I simply use a TextView that uses the selection as background. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" android:textSize="30dp" android:id="@+id/test_view_example" android:background="@drawable/test_selection"/> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/refresh" android:onClick="updateView" android:text="refresh"></Button> </LinearLayout> My Activity code is also very simple. public class TestDrawableStateActivity extends Activity { private final static int[] SELECTED_STATE = { android.R.attr.state_selected }; private final static int[] UNSELECTED_STATE = {}; private TextView textView; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); textView = (TextView) findViewById(R.id.test_view_example); } @Override protected void onResume() { super.onResume(); // Carichiamo la Drawable if(textView.getBackground().setState(SELECTED_STATE)){ textView.invalidate(); } } public void updateView(View view) { if(textView.getBackground().setState(SELECTED_STATE)){ textView.invalidate(); }; } } When Activity starts I try to set the state of my Drawable (the StateListDrawable) with the value SELECTED. It seems all very simple.... but the problem is that the state is not shown. If, later, I click a button and execute the method updateView() the state changes. Where is my problem? Where am I wrong? Thankx a lot Max

Using LINQ to create a simple login

- by JDWebs

I'm an C# ASP.NET beginner, so please excuse anything that's... not quite right! In short, I want to create a really basic login system: one which runs through a database and uses sessions so that only logged in users can access certain pages. I know how to do most of that, but I'm stuck with querying data with LINQ on the login page. On the login page, I have a DropDownList to select a username, a Textbox to type in a password and a button to login (I also have a literal for errors). The DropDownList is databound to a datatable called DT_Test. DT_Test contains three columns: UsernameID (int), Username (nchar(30)) and Password (nchar(30)). UsernameID is the primary key. I want to make the button's click event query data from the database with the DropDownList and Textbox, in order to check if the username and password match. But I don't know how to do this... Current Code (not a lot!): Front End: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Login_Test.aspx.cs" Inherits="Login_Login_Test" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Login Test</title> </head> <body> <form id="LoginTest" runat="server"> <div> <asp:DropDownList ID="DDL_Username" runat="server" Height="20px" DataTextField="txt"> </asp:DropDownList> <br /> <asp:TextBox ID="TB_Password" runat="server" TextMode="Password"></asp:TextBox> <br /> <asp:Button ID="B_Login" runat="server" onclick="B_Login_Click" Text="Login" /> <br /> <asp:Literal ID="LI_Result" runat="server"></asp:Literal> </div> </form> </body> </html> Back End: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class Login_Login_Test : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { Binder(); } } private void Binder() { using (DataClassesDataContext db = new DataClassesDataContext()) { DDL_Username.DataSource = from x in db.DT_Honeys select new { x.UsernameID, txt = x.Username }; DDL_Username.DataBind(); } } protected void B_Login_Click(object sender, EventArgs e) { if (TB_Password.Text != "") { using (DataClassesDataContext db = new DataClassesDataContext()) { } } } } I have spent hours searching and trying different code, but none of it seems to fit in for this context. Anyway, help and tips appreciated, thank you very much! I am aware of security risks etc. but this is not a live website or anything, it is simply for testing purposes as a beginner. *

AIDL based two way communication

- by sshasan

I have two apps between which I want some data exchanged. As they are running in different processes, so, I am using AIDL to communicate between them. Now, everything is happening really great in one direction (say my apps are A and B) i.e. data is being sent from A to B but, now I need to send some data from B to A. I noticed that we need to include the app with the AIDL in the build path of app where the AIDL method will be called. So in my case A includes B in its build path. For B to be able to send something to A, by that logic, B would need A in its build path. This would create a cycle. I am stuck at this point. And I cannot think of a work around this loop. Any help would be greatly appreciated :) . Thanks! ----EDIT---- So, I following the advice mentioned in one of the comments below, I have the following code In the IPCAIDL project the AIDL file resides, its contents are package ipc.android.aidl; interface Iaidl{ boolean pushBoolean(boolean flag); } This project is being used as a library in both the IPCServer and the IPC Client. The IPCServer Project has the service which defines what happens with the AIDL method. The file is booleanService.java package ipc.android.server; import ipc.android.aidl.Iaidl; import android.app.Service; import android.content.Intent; import android.os.IBinder; import android.os.RemoteException; import android.util.Log; public class booleanService extends Service { @Override public IBinder onBind(Intent intent) { return new Iaidl.Stub() { @Override public boolean pushBoolean(boolean arg0) throws RemoteException { Log.i("SERVER(IPC AIDL)", "Truth Value:"+arg0); return arg0; } }; } } The IPCClient file which calls this method is package ipc.android.client2; import ipc.android.aidl.Iaidl; import android.app.Activity; import android.content.ComponentName; import android.content.Context; import android.content.Intent; import android.content.ServiceConnection; import android.os.Bundle; import android.os.IBinder; import android.os.RemoteException; import android.view.View; import android.widget.Button; public class IPCClient2Activity extends Activity { Button b1; Iaidl iAIDL; boolean k = false; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); bindService(new Intent("ipc.android.server.booleanService"), conn, Context.BIND_AUTO_CREATE); startService(new Intent("ipc.android.server.booleanService")); b1 = (Button) findViewById(R.id.button1); b1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if(k){ k = false; } else{ k = true; } try { iAIDL.pushBoolean(k); } catch (RemoteException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }); } private ServiceConnection conn = new ServiceConnection() { @Override public void onServiceDisconnected(ComponentName name) { // TODO Auto-generated method stub } @Override public void onServiceConnected(ComponentName name, IBinder service) { iAIDL = Iaidl.Stub.asInterface(service); } }; } The manifest file for IPCServer includes the declaration of the service.
