  • Image Grabbing with False Referer

    - by Mr Carl
    Hey guys, I'm struggling with grabbing an image at the moment... sounds silly, but check out this link :P http://manga.justcarl.co.uk/A/Oishii_Kankei/31/1 If you get the image URL, the image loads. Go back, it looks like it's working fine, but that's just the browser loading up the cached image. The application was working fine before, I'm thinking they implemented some kind of Referer check on their images. So I found some code and came up with the following... $ref = 'http://www.thesite.com/'; $file = 'theimage.jpg'; $hdrs = array( 'http' = array( 'method' = "GET", 'header'= "accept-language: en\r\n" . "Accept:application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*\/*;q=0.5\r\n" . "Referer: $ref\r\n" . // Setting the http-referer "Content-Type: image/jpeg\r\n" ) ); // get the requested page from the server // with our header as a request-header $context = stream_context_create($hdrs); $fp = fopen($imgChapterPath.$file, 'rb', false, $context); fpassthru($fp); fclose($fp); Essentially it's making up a false referrer. All I'm getting back though is a bunch of gibberish (thanks to fpassthru) so I think it's getting the image, but I'm afraid to say I have no idea how to output/display the collected image. Cheers, Carl

    I'm new at android programming, I'm now trying to make some buttons, I configured these buttons using the following code: The MainActivity class : public class MainActivity extends Activity { /** Called when the activity is first created. */ Button st,nd,center; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); st = (Button)findViewById(R.id.st); st = (Button)findViewById(R.id.center); st = (Button)findViewById(R.id.nd); } } and the XML Layout: <?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" android:background="@drawable/background" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Hello from animation!!" /> <button android:layout_width="100dp" android:layout_height="50dp" android:text="1st half" android:id="@+id\st" /> // and the other two points defined the same way </LinearLayout> And i got that syntax error: error: Error: No resource type specified (at 'id' with value '@+id\st'). // and the same error with the other two buttons HINT: The R class is imported and accessible from the MainActivity class but it can't read R.id.

  • How can I create Wikipedia's footnote highlighting solely with jQuery

    - by andrew.bachman
    I would like to duplicate Wikipedia's footnote highlighting from in-text citation click solely in jQuery and CSS classes. I found a webpage that describes how to do so with CSS3 and then a JavaScript solution for IE. I would like however to do so solely with jQuery as the site I'm doing it on already has a bunch of jQuery elements. I've come up with a list of the process. In-Text Citation Clicked Replace highlight class with standard footnote class on <p> tag of footnotes that are already highlighted. Add highlight to the appropriate footnote Use jQuery to scroll down the page to appropriate footnote. I've come up with some jQuery so far but I'm extremely new to it relying heavy on tutorials and plugins to this point. Here is what I have with some plain English for the parts I haven't figured out yet. $('.inlineCite').click(function() { $('.footnoteHighlight').removeClass('footnoteHighlight').addClass('footnote'); //add highlight to id of highlightScroll //scroll to footnote with matching id }); If I had a method to pass a part of the selector into the function and turn it into a variable I believe I could pull it off. Most likely I'm sure one of you gurus will whip something up that puts anything I think I have done to shame. Any help will be greatly appreciated so thank you in advance. Cheers.

  • How to correctly load dependent JavaScript files

    - by Vaibhav Garg
    I am trying to extent a website page that displays google maps with the LabeledMarker. Google Maps API defines a class called GMarker which is extended by the LabeledMarker. The problem is, I cant seem to load the LabeledMarker script properly, i.e. after the Google API loads and I get the 'GMarker not defined' error. What is the correct way to specify the scripts in such cases? I am using ASP.NET's ClientScript.RegisterClientScriptInclude() first for the google API url and then immediately after with the LabeledMarker script file. The initial google API loader writes further script links that load the actual GMarker class. Shouldnt all those scripts be executed before the next script block(LabeledMarker script) is processed. I have checked the generated HTML and the script blocks are emitted in the right order. <script src="google api url" type="text/javascript"></script> ... (the above scripts uses document.write() etc to append further script blocks/sources) ... <script src="Scripts/LabeledMarker.js" type="text/javascript"></script> Once again, the LabeledMarker.js seems to get executed before the google API finishes loading.

  • Save Dialog on top of another custom dialog is behaving strangely!

    - by Raghu
    I have a save as image feature for charts in my application. The chart control is a custom user control with custom logic in them. It also has some scaling based on size, zoom etc. However, while saving them as an image I would like to give the user the option to set the size of the image (eg: 800x600 px @ 300 DPI). To do this I have created a Form with textboxes/checkboxes etc for various settings for image. One of these TextBoxes is for the file name. The file name textbox is readonly and is accompanied with a browse button which shows a SaveFileDialog when clicked. The user clicks "Save As Image" in the main form's menu. I show the ImageExportDialog using the code below: using(ImageExportDialog dlg = new ImageExportDialog()) { if(dlg.ShowDialog() == DialogResult.OK) { //get the settings selected by the user and generate the image } } In the ImageExportDialog, the user clicks on the browse button and the SaveFileDialog is shown as follows: using(SaveFileDialog dlg = new SaveFileDialog()) { if(dlg.ShowDialog() == DialogResult.OK) { txtFileName.Text = dlg.FileName; } } Now the problem is, when the user clicks on "Save" button in the SaveFileDialog, as expected the txtFileName.Text is set, but the parent custom dialog also seems to return from the ShowDialog method and the DialogResult is the same as the one for SaveFileDialog! The control then goes on to the "get the settings selected by the user and generate the image" part of the code above. Not really sure what I am doing wrong here!

  • What's wrong with this code to un-camel-case a string?

    - by omair iqbal
    Here is my attempt to solve the About.com Delphi challenge to un-camel-case a string. unit challenge1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type check = 65..90; TForm1 = class(TForm) Edit1: TEdit; Button1: TButton; procedure Button1Click(Sender: TObject); private { Private declarations } public { Public declarations } end; var Form1: TForm1; var s1,s2 :string; int : integer; implementation {$R *.dfm} procedure TForm1.Button1Click(Sender: TObject); var i: Integer; checks : set of check; begin s1 := edit1.Text; for i := 1 to 20 do begin int :=ord(s1[i]) ; if int in checks then insert(' ',s1,i-1); end; showmessage(s1); end; end. check is a set that contains capital letters so basically whenever a capital letter is encountered the insert function adds space before its encountered (inside the s1 string), but my code does nothing. ShowMessage just shows text as it was entered in Edit1. What have I done wrong?

  • Center aligned form with equal width labels

    - by James Goodwin
    I have a very simple web form which consists of labels and input fields, however I can not seem to find a way of aligning the form in the center of the page and for the labels to have an equal width so that they appear neatly next to each other, one under the other. The structure of my page is basically: <body> <div class="form"> <form method="post"> <fieldset> <label>Mobile:</label><input type="text" name="msisdn"><br/> <label>Code:</label><input type="text" name="code"><br/> <br/> <input type="image" src="submit-button.gif" alt="Submit"> <br/> <input type="checkbox" name="ts_and_cs"><label> Accept Terms and Conditions</label> <br/><br/> </fieldset> </form> </div> </body> Usually I would fix this by doing float:left on the label fields and setting a width on the labels, however for this I need the labels and input fields to be centered on the page. Also I am not able to set the width of the page (or any containing divs) as the page will be displayed on mobile devices with different screen sizes. Any suggestions as to how best style the form? Thanks

  • Flex: Linebreak problem with spark.components.TextArea inside a MXDataGridItemRenderer

    - by radgar
    Hi, I have a DataGrid that has a MXDataGridItemRenderer applied as an itemEditor to one of the columns. The editor includes a spark.components.TextArea control. By default, any text item editor of a datagrid closes itself when [enter] key is pressed.. Keeping this in mind; What I want to do is: Prevent editor from closing on [SHIFT+ENTER] key but accept the linebreak (I can do this, see code below) Close the editor on [ENTER] key but do not accept the linebreak (could not achieve this) Here is the current code in the MXDataGridItemRenderer: <s:MXDataGridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" focusEnabled="true" > <fx:Script> <![CDATA[ protected function onTxtDataKeyDown(event:KeyboardEvent):void { //Prevent editor from closing on [SHIFT+ENTER] key but accept the linebreak // » this works if (event.shiftKey && event.keyCode == 13) { event.stopImmediatePropagation(); } //Close the editor on [ENTER] key but do not accept the linebreak else if (event.keyCode == 13) { event.preventDefault(); } // » does not work } ]]> </fx:Script> <s:TextArea id="txtData" paddingTop="3" lineBreak="explicit" text="{dataGridListData.label}" verticalScrollPolicy="auto" horizontalScrollPolicy="off" keyDown="onTxtDataKeyDown(event)" /> I also tried the textInput event but that did not do the trick. So: How can I prevent the linebreak when the editor is closed on [enter] key? Any help is appreciated. Thanks. EDIT: If I change the spark.components.TextArea to mx.controls.TextArea, second part with event.preventDefault() will work as expected but then the first part where SHIFT+ENTER accepts the linebreak will not work.

  • IndexOutofRangeException while using WriteLine in nested Parallel.For loops

    - by Umar Asif
    I am trying to write kinect depth data to a text file using nested Parallel.For loops with the following code. However, it gives IndexOutofRangeException. The code works perfect if using simple for loops but it hangs the UI since the depth format is set to 640x480 causing the loops to write 307200 lines in the text file at 30fps. Therefore, I switched to Parallel. For scheme. If I omit the writeLine command from the nested loops, the code works fine, which indicates that the IndexOutofRangeException is arising at the writeline command. I do not know how to troubleshoot this. Please advise. Any better workarounds to avoid UI freezing? Thanks. using (DepthImageFrame depthImageframe = d.OpenDepthImageFrame()) { if (depthImageframe == null) return; depthImageframe.CopyPixelDataTo(depthPixelData); swDepth = new StreamWriter(@"E:\depthData.txt", false); int i = 0; Parallel.For(0, depthImageframe.Width, delegate(int x) { Parallel.For(0, depthImageframe.Height, delegate(int y) { p[i] = sensor.MapDepthToSkeletonPoint(depthImageframe.Format, x, y, depthPixelData[x + depthImageframe.Width * y]); swDepth.WriteLine(i + "," + p[k].X + "," + p[k].Y + "," + p[k].Z); i++; }); }); swDepth.Close(); } }

  • How to check if JavaScript object is JSON

    - by Wei Hao
    I have a nested JSON object that I need to loop through, and the value of each key could be a String, JSON array or another JSON object. Depending on the type of object, I need to carry out different operations. Is there any way I can check the type of the object to see if it is a String, JSON object or JSON array? I tried using typeof and instanceof but both didn't seem to work, as typeof will return an object for both JSON object and array, and instanceof gives an error when I do obj instanceof JSON. To be more specific, after parsing the JSON into a JS object, is there any way I can check if it is a normal string, or an object with keys and values (from a JSON object), or an array (from a JSON array)? For example: JSON var data = {"hi": {"hello": ["hi1","hi2"] }, "hey":"words" } JavaScript var jsonObj = JSON.parse(data); var level1 = jsonObj.hi; var text = jsonObj.hey; var arr = level1.hello; //how to check if level1 was formerly a JSON object? //how to check if arr was formerly a JSON array? //how to check if text is a string?

Component code looks like this (EditableCanvas.mxml): <?xml version="1.0" encoding="utf-8"?> <mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script> <mx:Image id="editTextImage" source="@Embed('/../assets/icons/small/edit.png')"/> </mx:Canvas> The code that is using the code looks like this: <view:EditableCanvas width="290" height="120" backgroundColor="#FFFFFF" horizontalScrollPolicy="off" borderStyle="solid" cornerRadius="3"> <mx:Text id="textContentBox" width="270" fontFamily="nautics" fontSize="12" text="{_text}"/> </view:EditableCanvas>

  • Generating dynamic css using php and javascript

    - by Onkar Deshpande
    I want to generate tooltip based on a dynamically changing background image in css. This is my my_css.php file. <?php header('content-type: text/css'); $i = $_GET['index']; if($i == 0) $bg_image_path = "../bg_red.jpg"; elseif ($i == 1) $bg_image_path = "../bg_yellow.jpg"; elseif ($i == 2) $bg_image_path = "../bg_green.jpg"; elseif ($i == 3) $bg_image_path = "../bg_blue.jpg"; ?> .tooltip { white-space: nowrap; color:green; font-weight:bold; border:1px solid black;; font-size:14px; background-color: white; margin: 0; padding: 7px 4px; border: 1px solid black; background-image: url(<?php echo $bg_image_path; ?>); background-repeat:repeat-x; font-family: Helvetica,Arial,Sans-Serif; font-family: Times New Roman,Georgia,Serif; filter:alpha(opacity=85); opacity:0.85; zoom: 1; } In order to use this css I added <link rel="stylesheet" href="css/my_css.php" type="text/css" media="screen" /> in my html <head> tag of javascript code. I am thinking of passing different values of 'index' so that it would generate the background image dynamically. Can anyone tell me how should I pass such values from a javascript ? I am creating the tooltip using var tooltip = document.createElement("div"); document.getElementById("map").appendChild(tooltip); tooltip.style.visibility="hidden"; and I think before calling this createElement, I should set background image.

  • ASP.Net ListBox selections not working in Panel?

    - by larryq
    Hi everyone, I'm having trouble processing a listbox after selecting some items from it. In my markup, the listbox is contained within an asp:panel and is populated during page load in the codebehind. That part works fine. It's when I select various items and submit that I have trouble. My handler loops through the listbox items but doesn't see any as being selected. I'm not sure why. Here's the markup: <asp:Panel ID="panEdit" runat="server" Height="180px" Width="400px" CssClass="ModalWindow"> <table width="100%"> <asp:label runat = "server">Choose your items</asp:label> <tr> <td> <asp:ListBox ID="lstFundList" runat="server" SelectionMode="Multiple" OnLoad="lstFundList_LoadData"> </asp:ListBox> </td> </tr> </table> <asp:Button ID="btnUpdate" runat="server" Text="Update" OnClick="btnUpdate_OnClick"/> <asp:Button ID="btnCancel" runat="server" Text="Cancel" OnClientClick="$find('ModalPopupExtender1').hide(); return false;" /> </asp:Panel> In my btnUpdate_OnClick handler I can't see any listbox items that are marked as selected. I assume something strange is going on with respect to postback and the panel?

  • Filtering on a left join in SQLalchemy

    - by Adam Ernst
    Using SQLalchemy I want to perform a left outer join and filter out rows that DO have a match in the joined table. I'm sending push notifications, so I have a Notification table. This means I also have a ExpiredDeviceId table to store device_ids that are no longer valid. (I don't want to just delete the affected notifications as the user might later re-install the app, at which point the notifications should resume according to Apple's docs.) CREATE TABLE Notification (device_id TEXT, time DATETIME); CREATE TABLE ExpiredDeviceId (device_id TEXT PRIMARY KEY, expiration_time DATETIME); Note: there may be multiple Notifications per device_id. There is no "Device" table for each device. So when doing SELECT FROM Notification I should filter accordingly. I can do it in SQL: SELECT * FROM Notification LEFT OUTER JOIN ExpiredDeviceId ON Notification.device_id = ExpiredDeviceId.device_id WHERE expiration_time == NULL But how can I do it in SQLalchemy? sess.query( Notification, ExpiredDeviceId ).outerjoin( (ExpiredDeviceId, Notification.device_id == ExpiredDeviceId.device_id) ).filter( ??? ) Alternately I could do this with a device_id NOT IN (SELECT device_id FROM ExpiredDeviceId) clause, but that seems way less efficient.

  • Binary files printing and desired precision

    - by yCalleecharan
    Hi, I'm printing a variable say z1 which is a 1-D array containing floating point numbers to a text file so that I can import into Matlab or GNUPlot for plotting. I've heard that binary files (.dat) are smaller than .txt files. The definition that I currently use for printing to a .txt file is: void create_out_file(const char *file_name, const long double *z1, size_t z_size){ FILE *out; size_t i; if((out = _fsopen(file_name, "w+", _SH_DENYWR)) == NULL){ fprintf(stderr, "***> Open error on output file %s", file_name); exit(-1); } for(i = 0; i < z_size; i++) fprintf(out, "%.16Le\n", z1[i]); fclose(out); } I have three questions: Are binary files really more compact than text files?; If yes, I would like to know how to modify the above code so that I can print the values of the array z1 to a binary file. I've read that fprintf has to be replaced with fwrite. My output file say dodo.dat should contain the values of array z1 with one floating number per line. I have %.16Le up in my code but I think that %.15Le is right as I have 15 precision digits with long double. I have put a dot (.) in the width position as I believe that this allows expansion to an arbitrary field to hold the desired number. Am I right? As an example with %.16Le, I can have an output like 1.0047914240730432e-002 which gives me 16 precision digits and the width of the field has the right width to display the number correctly. Is placing a dot (.) in the width position instead of a width value a good practice? Thanks a lot...
