    - by Victorgalaxy
    FYI, here is my code: [index.html] <script type="text/javascript" src="js/script.js"></script> [script.js] $(document).ready(function() { $('#buttonEphone').click(function() { $('#apDiv2').load("ePhone.html, #content"); }); }); "ePhone.html" contain some lightbox effect.

  • Making a button click and process using javascript with Asp.Net

    - by user944919
    I'm having two buttons and one button is hidden. Now when I click the visible button I need to do two things 1.Open Iframe. 2.Automatically make the 2nd Button(Hidden)to be clicked. When the second button is clicked I need to display the message on top of the IFrame which I have mentioned as function showStickySuccessToast() Now I am able to open IFrame but I'm unable to make the Hidden button clicked automatically. This is what I'm having: <script type="text/javascript"> $(document).ready(function(){ $("#<%=Button1.ClientID%>").click(function(event){ $('#<%=TextBox1.ClientID%>').change(function () { $('#various3').attr('href', $(this).val()); }); }); function showStickySuccessToast() { $().toastmessage('showToast', { text: 'Finished Processing!', sticky: false, position: 'middle-center', type: 'success', closeText: '', close: function () { } }); } }) </script> Here are my two buttons how I'm working with: <a id="various3" href="#"><asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="Button2_Click"/></a> <asp:Button ID="Button2" runat="server" Text="Button" Visible="False" OnClick="Button2_Click"/> And in the button2_Click event: Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, GetType(Page), "Script", "showStickySuccessToast();", True) End Sub

  • The "correct" way of using multilingual support

    - by Felipe Athayde
    I just began working with ASP.NET and I'm trying to bring with me some coding standards I find healthy. Among such standards there is the multilingual support and the use of resources for easily handling future changes. Back when I used to code desktop applications, every text had to be translated, so it was a common practice to have the language files for every languages I would want to offer to the customers. In those files I would map every single text, from button labels to error messages. In ASP.NET, with the help of Visual Studio, I have the resort of using the IDE to generate such Resource Files (from Tools - Generate Local Resource), but then I would have to fill my webpages with labels - at least that is what I've learned from articles and tutorials. However, such approach looks a bit odd and I'm tempted to guess it doesn't smell that good as well. Now to the question: 1) Should I keep every single text in my website as labels and manage its contents in the resource files? It looks/feels odd specially when considering a text with several paragraphs. 2) Whenever I add/remove something, e.g.: a button, to an aspx file I would have to add it to the resource file as well, because generating the resource file again would simply override all my previous changes to it. That doesn't feel like a reusable code at all for me. Any comment suggestion on this one? Perhaps I got it all wrong from tutorials as it doesn't seem like a standardized matter - specially if it required recompiling the entire application whenever some change has to be done.

  • Where do you put your dependencies?

    - by The All Foo
    If I use the dependency injection pattern to remove dependencies they end up some where else. For example, Snippet 1, or what I call Object Maker. I mean you have to instantiate your objects somewhere...so when you move dependency out of one object, you end up putting it another one. I see that this consolidates all my dependencies into one object. Is that the point, to reduce your dependencies so that they all reside in a single ( as close to as possible ) location? Snippet 1 - Object Maker <?php class ObjectMaker { public function makeSignUp() { $DatabaseObject = new Database(); $TextObject = new Text(); $MessageObject = new Message(); $SignUpObject = new ControlSignUp(); $SignUpObject->setObjects($DatabaseObject, $TextObject, $MessageObject); return $SignUpObject; } public function makeSignIn() { $DatabaseObject = new Database(); $TextObject = new Text(); $MessageObject = new Message(); $SignInObject = new ControlSignIn(); $SignInObject->setObjects($DatabaseObject, $TextObject, $MessageObject); return $SignInObject; } public function makeTweet( $DatabaseObject = NULL, $TextObject = NULL, $MessageObject = NULL ) { if( $DatabaseObject == 'small' ) { $DatabaseObject = new Database(); } else if( $DatabaseObject == NULL ) { $DatabaseObject = new Database(); $TextObject = new Text(); $MessageObject = new Message(); } $TweetObject = new ControlTweet(); $TweetObject->setObjects($DatabaseObject, $TextObject, $MessageObject); return $TweetObject; } public function makeBookmark( $DatabaseObject = NULL, $TextObject = NULL, $MessageObject = NULL ) { if( $DatabaseObject == 'small' ) { $DatabaseObject = new Database(); } else if( $DatabaseObject == NULL ) { $DatabaseObject = new Database(); $TextObject = new Text(); $MessageObject = new Message(); } $BookmarkObject = new ControlBookmark(); $BookmarkObject->setObjects($DatabaseObject,$TextObject,$MessageObject); return $BookmarkObject; } }

  • Bootstrap inline button dropdown within <p> jumbotron

    - by C.B.
    Currently I have a jumbotron setup with some paragraph text, and I would like to stick a button dropdown inline with the text. Dropdown button <span class="btn-group"> <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown"> Button... <span class="caret"></span> </button> <ul class="dropdown-menu" role="menu"> <li><a href="#">Opt 1</a></li> <li><a href="#">Opt 2</a></li> </ul> </span> Jumbotron <div class="jumbotron"> <h1>Hello!</h1> <p>Welcome</p> <p>Another paragraph <!-- dropdown is here --> </p> </div> <!-- jumbotron --> If the dropdown is within the <p> tag, it does not "dropdown" (but renders). If it is outside of the <p> tag it functions fine, but I would like it to be inline with the text and need the text to be in the <p> tag to get the style. Any ideas? Things to note -- If I replace the <span> tags with <div> tags, it will work fine within the <p> tags, but won't be inline.

  • How would I make this faster? Parsing Word/sorting by heading [on hold]

    - by Doof12
    Currently it takes about 3 minutes to run through a single 53 page word document. Hopefully you all have some advice about speeding up the process. Code: import win32com.client as win32 from glob import glob import io import re from collections import namedtuple from collections import defaultdict import pprint raw_files = glob('*.docx') word = win32.gencache.EnsureDispatch('Word.Application') word.Visible = False oFile = io.open("rawsort.txt", "w+", encoding = "utf-8")#text dump doccat= list() for f in raw_files: word.Documents.Open(f) doc = word.ActiveDocument #whichever document is active at the time doc.ConvertNumbersToText() print doc.Paragraphs.Count for x in xrange(1, doc.Paragraphs.Count+1):#for loop to print through paragraphs oText = doc.Paragraphs(x) if not oText.Range.Tables.Count >0 : results = re.match('(?P<number>(([1-3]*[A-D]*[0-9]*)(.[1-3]*[0-9])+))', oText.Range.Text) stylematch = re.match('Heading \d', oText.Style.NameLocal) if results!= None and oText.Style != None and stylematch != None: doccat.append((oText.Style.NameLocal, oText.Range.Text[:len(results.group('number'))],oText.Range.Text[len(results.group('number')):])) style = oText.Style.NameLocal else: if oText.Range.Font.Bold == True : doccat.append(style, oText) oFile.write(unicode(doccat)) oFile.close() The for Paragraph loop obviously takes the most amount of time. Is there some way of identifying and appending it without going through every Paragraph?

  • HTML email image inverts on link click Outlook 07/10/13

    I'm having an issue on a HTML email in Word rendered Outlooks (2007, 2010, 2013) where I click an image link, and when the mouse is clicked, the image inverts... Here is the code below... <td align="left" width="360" valign="top" style="mso-table-lspace: 0pt; mso-table-rspace: 0pt; border-collapse: collapse;" class="hide"> <a href="#" target="_blank"> <img src="test.jpg" width="360" height="528" alt="alt tag" style="display:block;" class="img_mob centertable" border="0" align="left"> </a> </td> Here is a comparison on the image clicked/not clicked... I have tried putting a text-decoration: none on the link. All the links are styled inline as well. This is the only image that it is having this issue on the email, so tried re-saving the image with no luck. The image is saved as a JPEG and SRGB from a Photoshop PSD. Any ideas? Thanks.

  • Is there any PDF parser written in objective-c or c?

    - by user549683
    I'm writing a pdf reader iPhone application. I know how to show pdf file in view using CGPDF** classes in iOS. What I want to do now is to search text in pdf file, and highlight the searched text. So, I need a library which can detect what text is in what position. Besides, I want the library able to handle unicode and Chinese characters. I've searched for a few days but still cannot find anything suitable. I've tried xpdf, but it is written in c++. I don't know how to use c++ code in iPhone app. I've also tried http://www.codeproject.com/KB/cpp/ExtractPDFText.aspx but it does not handle Chinese characters. I've tried to code by myself, but the encoding in PDF is really complicated. For example, I don't know what to refer to when I want to decode the text by the following font: 8 0 obj << /Type /Font /Subtype /Type0 /Encoding /Identity-H /BaseFont /RNXJTV+PMingLiU /DescendantFonts [ 157 0 R ] >> endobj 157 0 obj << /Type /Font /Subtype /CIDFontType2 /BaseFont /RNXJTV+PMingLiU /CIDSystemInfo << /Registry (Adobe) /Ordering (CNS1) /Supplement 0 >> /FontDescriptor 158 0 R /W 161 0 R /DW 1000 /CIDToGIDMap 162 0 R >> endobj 158 0 obj << /Type /FontDescriptor /Ascent 801 /CapHeight 711 /Descent -199 /Flags 32 /FontBBox [0 -199 999 801] /FontName /RNXJTV+PMingLiU /ItalicAngle 0 /StemV 0 /Leading 199 /MaxWidth 1000 /XHeight 533 /FontFile2 159 0 R >> endobj

  • Show iPad keyboard on select, focus or always (jQuery)

    - by Ryan
    I have a web app that is using jQuery to replace the RETURN key with TAB so that when I user presses return the form is not submitted but rather the cursor moves to the next text field. This works in all browsers but only 1/2 works on the iPad. On the iPad the next field is highlighted but the keyboard is hidden. How can I keep the keyboard visible or force it somehow? Here's my code (thanks to http://thinksimply.com/blog/jquery-enter-tab): function checkForEnter (event) { if (event.keyCode == 13) { currentBoxNumber = textboxes.index(this); if (textboxes[currentBoxNumber + 1] != null) { nextBox = textboxes[currentBoxNumber + 1] nextBox.focus(); nextBox.select(); event.preventDefault(); return false; } } } Drupal.behaviors.formFields = function(context) { $('input[type="text"]').focus(function() { $(this).removeClass("idleField").addClass("focusField"); }); $('input[type="text"]').blur(function() { $(this).removeClass("focusField").addClass("idleField"); }); // replaces the enter/return key function with tab textboxes = $("input.form-text"); if ($.browser.mozilla) { $(textboxes).keypress (checkForEnter); } else { $(textboxes).keydown (checkForEnter); } };

  • Which CSS identifier is used for the selected tab in tabbed tables in browsers other than IE?

    - by David Navarre
    When you have a table on a form in Notes, you can choose to display only one row at a time (via the Special Table Row Display parameter on the Table Rows tab of the Table properties). In a Notes document displayed using Internet Explorer that contains such a table, a row is displayed with a cell for each "tab". The TD that serves as the tab for the selected "Notes table row" is assigned <td class="dominoSelTopTab">, while the other tabs get <td class="dominoTopTab">. However, when using other browsers, it's not nearly as simple. In Firefox, each "tab" ends up as a single-celled-single-row-table within the table with very little to identify it. <td><table border="1" cellpadding="2"> <tr><td><div align="center"><b>Tab 2</b></div></td></tr> </table></td> A non-selected tab would show as follows: <td><table border="1" cellpadding="2"> <tr><td><div align="center"><a name="1." href="/Projects/MyCSS.nsf/0c3b9489476440c085257a62006d97d6/d482a1767a4af77f85257a62006db064?OpenDocument&amp;TableRow=1.0#1." target="_self">Tab 1</a></div></td></tr> </table></td> So, the question is, how do I identify the selected tabs and the non-selected tabs when not using IE? Note: For those who are not Notes developers, the HTML is auto-generated from the visual design as laid out in the Notes designer client. I would replace it all with manual HTML, except there is so much of it that doing so would consume far too much time.

  • Stop writing blank line at the end of CSV file (using MATLAB)

    - by Grant M.
    Hello all ... I'm using MATLAB to open a batch of CSV files containing column headers and data (using the 'importdata' function), then I manipulate the data a bit and write the headers and data to new CSV files using the 'dlmwrite' function. I'm using the '-append' and 'newline' attributes of 'dlmwrite' to add each line of text/data on a new line. Each of my new CSV files has a blank line at the end, whereas this blank line was not there before when I read in the data ... and I'm not using 'newline' on my final call of 'dlmwrite'. Does anyone know how I can keep from writing this blank line to the end of my CSV files? Thanks for your help, Grant EDITED 5/18/10 1:35PM CST - Added information about code and text file per request ... you'll notice after performing the procedure below that there appears to be a carriage return at the end of the last line in the new text file. Consider a text file named 'textfile.txt' that looks like this: Column1, Column2, Column3, Column4, Column 5 1, 2, 3, 4, 5 1, 2, 3, 4, 5 1, 2, 3, 4, 5 1, 2, 3, 4, 5 1, 2, 3, 4, 5 Here's a sample of the code I am using: % import data importedData = importdata('textfile.txt'); % manipulate data importedData.data(:,1) = 100; % store column headers into single comma-delimited % character array (for easy writing later) columnHeaders = importedData.textdata{1}; for counter = 2:size(importedData.textdata,2) columnHeaders = horzcat(columnHeaders,',',importedData.textdata{counter}); end % write column headers to new file dlmwrite('textfile_updated.txt',columnHeaders,'Delimiter','','newline','pc') % append all but last line of data to new file for dataCounter = 1:(size(importedData.data,2)-1) dlmwrite('textfile_updated.txt',importedData.data(dataCounter,:),'Delimiter',',','newline','pc','-append') end % append last line of data to new file, not % creating new line at end dlmwrite('textfile_updated.txt',importedData.data(end,:),'Delimiter',',','-append')

  • My java program seems to be skipping over the try{}, executing the catch{} and then throwing a NullPointerException. What should I do?

    - by Matt Bolopue
    I am writing a program that calculates the number of words, syllables, and sentences in any given text file. I don't need help finding those numbers, however my program (which currently should only find the number of words in the text file) will not import the text file even when I type in the name of the file correctly. The text file is in the same folder as the source code. Instead it tells me every time that what I typed in has the wrong file extension (see my catch{}) and then proceeds to throw a null pointer. I am at a loss for what could be causing it. Any suggestions? import java.io.*; import java.util.*; public class Reading_Lvl_Calc { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub int words = 0; String fileName; Scanner scan; Scanner keyread = new Scanner(System.in); System.out.println("Please enter a file name (or QUIT to exit)"); fileName = keyread.nextLine(); File doc = new File(fileName); //while(scan.equals(null)){ try { scan = new Scanner(doc); } catch(Exception e) { if(fileName.substring(fileName.indexOf(".")) != ".txt") System.out.println("I'm sorry, the file \"" + fileName + "\" has an invalid file extension."); else System.out.println("I am sorry, the file \"" + fileName + " \" cannot be found.\n The file must be in the same directory as this program"); scan = null; } // } while(scan.hasNext()){ words++; scan.next(); } System.out.println(words); } }

I have look in VisPDF source and found, that: Abscissa := Angle * Pi / 180; X := XProjection(X) + StrHeight * sin(Abscissa); Y := (YProjection(Y)) - StrHeight * cos(Abscissa); MtxA := cos(Abscissa); MtxB := sin(Abscissa); SetTextMatrix(MtxA, MtxB, -MtxB, MtxA, X, Y); with SetTextMatrix() show up the bug. comment out this line, DecimalSeparator is right, but no text in my pdf. procedure TVPDFPage.SetTextMatrix(a, b, c, d, x, y: Single); var S: AnsiString; begin S := _CutFloat(a) + ' ' + _CutFloat(b) + ' ' + _CutFloat(c) + ' ' + _CutFloat(d) + ' ' + _CutFloat(x) + ' ' + _CutFloat(y) + ' Tm'; SaveToPageStream(S); end; procedure TVPDFPage.SaveToPageStream(ValStr: AnsiString); begin PageContent.Add(string(ValStr)); // PageContent: TStringList; end; I don't understand this function. Can somebody help? VisPDF does not use any DLL or other software to create PDF files. Using VisPDF is very easy and have good examples.

  • How to hide an dom element after creating it on the fly with Jquery ?

    - by ismaelsow
    I am trying to build a form where users can add a text field by clicking on a "add option" button. They can also remove added fields by a "remove option" link created on the fly by Jquery, along with the text field. My code looks like this : $(document).ready(function(){ $("#add_option").click(function(){ var form = $("form"); var input_field = '<input type="text" />'; var delete_link = '<a href="#">remove</a>'; form.append(input_field + delete_link); return false; }); $("a").click(function(){ alert('clicked'); return false; }); }); This code is not working : when I click on the "add_option" button, a new text field and the "delete_link" appear. But when clicking on the "delete_link" created by JQuery, the browser follows the link instead of launching a pop-up displaying "clicked". Any idea ? Thanks !

  • Keyboard not dismissed

    - by sgosha
    I am developing a messaging application that have SMS.app-like UI. Conversation screen has text input field at the bottom which is moved up with keyboard. Tapping on conversation area dismisses keyboard by calling resignFirstResponder method on UITextView that we use. This usually works fine, but users report a weird bug which I can't reproduce and fix. People say that sometimes onscreen keyboard doesn't go away when they tap on conversation area, though text input field loses input focus. Once the view enters that abnormal state users are able to type with keyboard, but text that is being entered is not visible anywhere. This bug happens in one of conversation views and since then no one text input field in other views doesn't work as expected. The only way to stop this weird behavior is killing application from multitasking bar. Even more weird thing is that keyboard stays visible while navigating between view controllers in UINavigationController. I noticed two things: - if tap on ' Anyone else experiencing same problems. Any ideas on what may cause this bug?

  • Setting initial state of a JSF component to invalid

    - by user359391
    Hi there I have a small JSF application where the user is required to enter some data about themselves. For each component on the page that has required="true" I want to show an icon depending if there is data in the field or not. My problem is that when the page is initially shown all fields are valid, even if they do not have any data in them. So my question is how I can set a component to be invalid based on if there is data in the field or not? After a submit of the page (or after the component loses focus) the icon is shown properly, it is only on the initial page load I have a problem. (i.e there is no post data) Here is my xhtml for a component that needs to be validated: <s:decorate id="employeeIdDecoration" template="/general/util/errorStyle.xhtml"> <ui:define name="label">#{messages['userdetails.employeeId']}</ui:define> <h:inputText value="#{authenticator.user.employeeId}" required="true"> <a4j:support event="onblur" reRender="employeeIdDecoration" bypassUpdates="true"/> </h:inputText> the template: <s:label styleClass="#{invalid?'error':''}"> <ui:insert name="label"/> <s:span styleClass="required" rendered="#{required}">*</s:span> </s:label> <span class="#{invalid?'error':''}"> <s:validateAll> <ui:insert/> </s:validateAll> <h:graphicImage value="/resources/redx.png" rendered="#{invalid}" height="16" width="16" style="vertical-align:middle;"/> <h:graphicImage value="/resources/Checkmark.png" rendered="#{!invalid}" height="16" width="16" style="vertical-align:middle;"/> </span> Any help will be appreciated.

  • How do I place widgets above and below a listview?

    - by Jay Askren
    I have a list view and want to put stuff both above(on the y axis) and below(y axis) it including images, text views, and a row of buttons. Below is a simplified version of what I am creating. Unfortunately the list covers(i.e. above on the z axis) the header so the header text is not visible instead of being underneath (on the y axis) <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <TextView android:id="@+id/footer" android:text="footer" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentBottom="true" /> <ListView android:id="@+id/list_view" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_above="@id/footer" android:background="#ff9999ff"/> <TextView android:id="@+id/header" android:text="header" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentTop="true" android:layout_above="@id/list_view" android:baselineAlignBottom="false" /> </RelativeLayout> Here is the corresponding Activity class: public class SampleListActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.list_activity); } }
