  • Selective emboldeing of text in a webpage

    while printing out utf-8 characters onto a webpage, if encapsulate them with they get emboldened, but anything else, the page turns blank.

  • How to allow to allow admins to edit my app's config files without UAC elevation?

    - by Justin Grant
    My company produces a cross-platform server application which loads its configuration from user-editable configuration files. On Windows, config file ACLs are locked down by our Setup program to allow reading by all users but restrict editing to Administrators and Local System only. Unfortunately, on Windows Server 2008, even local administrators no longer have admin privileges (because of UAC) unless they're running an elevated app. This has caused complaints from users who cannot use their favorite text editor to open and save config files changes-- they can open the files (since anyone can read) but can't save. Anyone have recommendations for what we can do (if anything) in our app's Setup to make editing easier for admins on Windows Server 2008? Related questions: if a Windows Server 2008 admin wants to edit an admins-only config file, how does he normally do it? Is he forced to use a text editor which is smart enough to auto-elevate when elevation is needed, like Windows Explorer does in response to access denied errors? Does he launch the editor from an elevated command-prompt window? Something else?

  • Awk filtering values between two files when regions intersect (any solutions welcome)

    - by user964689
    This is building upon an earlier question Awk conditional filter one file based on another (or other solutions) I have an awk program that outputs a column from rows in a text file 'refGene.txt if values in that row match 2 out of 3 values in another text file. I need to include an additional criteria for finding a match between the two files. The criteria is inclusion if the range of the 2 numberical values specified in each row in file 1 overlap with the range of the two values in a row in refGene.txt. An example of a line in File 1: chr1 10 20 chr2 10 20 and an example line in file 2(refGene.txt) of the matching columns ($3, $5, $ 6): chr1 5 30 Currently the awk program does not treat this as a match because although the first column matches neither the 2nd or 3rd columns do no. But I would like a way to treat this as a match because the region 10-20 in file 1 is WITHIN the range of 5-30 in refGene.txt. However the second line in file 1 should NOT match because the first column does not match, which is necessary. If there is a way to include cases when any of the range in file 1 overlaps with any of the range in refGene.txt that would be really helpful. It should also replace the below conditional statements as it would also find all the cases currently described below. Please let me know if my question is unclear. Any help is really appreciated, thanks it advance! (solutions do not have to be in awk) Rubal FILES=/files/*txt for f in $FILES ; do awk ' BEGIN { FS = "\t"; } FILENAME == ARGV[1] { pair[ $1, $2, $3 ] = 1; next; } { if ( pair[ $3, $5, $6 ] == 1 ) { print $13; } } ' $(basename $f) /files/refGene.txt > /files/results/$(basename $f) ; done

  • Dojo Widgets not rendering when returned in response to XhrPost

    - by lazynerd
    I am trying to capture the selected item in a Dijit Tree widget to render remaining part of the web page. Here is the code that captures the selected item and sends it to Django backend: <div dojoType="dijit.Tree" id="leftTree" store="leftTreeStore" childrenAttr="folders" query="{type:'folder'}" label="Explorer"> <script type="dojo/method" event="onClick" args="item"> alert("Execute of node " + termStore.getLabel(item)); var xhrArgs = { url: "/load-the-center-part-of-page", handleAs: "text", postData: dojo.toJson(leftTreeStore.getLabel(item), true), load: function(data) { dojo.byId("centerPane").innerHTML = data; //window.location = data; }, error: function(error) { dojo.byId("centerPane").innerHTML = "<p>Error in loading...</p>"; } } dojo.byId("centerPane").innerHTML = "<p>Loading...</p>"; var deferred = dojo.xhrPost(xhrArgs); </script> </div> The remaining part of the page contains HTML code with dojo widgets. This is the code sent back as 'response' to the select item event. Here is a snippet: <div dojoType="dijit.layout.TabContainer" id="tabs" jsId="tabs"> <div dojoType="dijit.layout.BorderContainer" title="Dashboard"> <div dojoType="dijit.layout.ContentPane" region="bottom"> first tab </div> </div> <div dojoType="dijit.layout.BorderContainer" title="Compare"> <div dojoType="dijit.layout.ContentPane" region="bottom"> Second Tab </div> </div> </div> It renders this html 'response' but without the dojo widgets. Is handleAs: "text" in XhrPost the culprit here?

  • find word and score based on positions

    - by ryder1211212
    hey guys i have a textfile i have divided it into 4 parts. i want to search each part for the words that appear in each part and score that word exmaple welcome to the national basketball finals,the basketball teams here today have come a long way. without much delay lets play basketball. i will want to return national = 1 as it appears only in one part etc am working on determining text context using word position. am working with c# and not very good in text processing basically if a word appears in the 4 sections it scores 4 if a word appears in the 3 sections it scores 3 if a word appears in the 2 sections it scores 2 if a word appears in the 1 section it scores 1 thanks in advance so far i have this var s = "welcome to the national basketball finals,the basketball teams here today have come a long way. without much delay lets play basketball. "; var numberOfParts = 4; var eachPartLength = s.Length / numberOfParts; var parts = new List<string>(); var words = Regex.Split(s, @"\W").Where(w => w.Length > 0); // this splits all words, removes empty strings var wordsIndex = 0; for (int i = 0; i < numberOfParts; i++) { var sb = new StringBuilder(); while (sb.Length < eachPartLength && wordsIndex < words.Count()) { sb.AppendFormat("{0} ", words.ElementAt(wordsIndex)); wordsIndex++; } // here you have the part Response.Write("[{0}]"+ sb); parts.Add(sb.ToString()); var allwords = parts.SelectMany(p => p.Split(' ').Distinct()); var wordsInAllParts = allwords.Where(w => parts.All(p => p.Contains(w))).Distinct();

  • Implement a custom editor in Visual Studio 2008 or 2010

    - by David Montgomery
    Hi, I'm trying to find documentation on how one would go about creating a custom editor plug-in for VS2008 or VS2010. The file syntax I want to edit is from a tool called TemplateMaschine by Stefan Sarstedt. An example of the template syntax: <%@ Assembly Name="System.Xml" %> <%@ Import NameSpace="System.Xml" %> <%@ Import NameSpace="System.Collections" %> <%@ Argument Name="className" Type="string" %> <%@ Argument Name="attributes" Type="ArrayList" %> public class <%=className%> { <% foreach(string attr in attributes) { %> public string <%=attr%>; <% } %> } The most important editor features for me would be real-time syntax checking and code completion. If we could get those features, it would save us THOUSANDS of man-hours. Failing to incorporate a custom editor into Studio, maybe there is some open source text editor project out there that might be easy to extend for my purposes? I've looked a little at Eclipse, but I would think code completion won't be an option (also, my Java stinks). Another possibility might be extending the SharpDevelop text editor component. Ideas and suggestions welcome!

  • Effective Method to Manage and Search Through 100,000+ Objects Instantly? (C#)

    - by Kirk
    I'm writing a media player for enthusiasts with large collections (over 100,000 tracks) and one of my main goals is speed in search. I would like to allow the user to perform a Google-esque search of their entire music collection based on these factors: Song Path and File Name Items in ID3 Tag (Title, Artist, Album, etc.) Lyrics What is the best way for me to store this data and search through it? Currently I am storing each track in an object and iterating over an array of these objects checking each of their variables for string matches based on given search text. I've run into problems though where my search is not effective because it is always a phrase search and I'm not sure how to make it more fuzzy. Would an internal DB like SQLlite be faster than this? Any ideas on how I should structure this system? I also need playlist persistence, so that when they close the app and open the app their same playlist loads immediately. How should I store the playlist information so it can load quickly when the application starts? Currently I am JSON encoding the entire playlist, storing it in a text file, and reading it into the ListView at runtime, but it is getting sluggish over 20,000 tracks. Thanks!

  • How to Implement Custom List View for the list Items in Android Application

    - by avadhani
    I had a problem with the list view having both parent list and the child list of the list activity(implemented through database query). I wish to show them differing their properties by changing the text style (parent list items are in bold, child list items are in normal style). The following is the code from which all the child and parent list items having the same style(bold): String sql = "SELECT Parentid,Childid,Name from (select com.Parentid, com.Childid, com.Name from table1 mem inner join table2 cd on mem.column1=cd.column1 inner join table3 com on com.childid = mem.childid where Parentid is NULL UNION SELECT com.Parentid, com.Childid,com.Name from table1 mem inner join table3 com on com.childid = mem.childid inner join table2 cd on mem.column1=cd.column1 where Parentid is NOT NULL) a group by Parentid, Childid;"; Cursor cdata = myDbHelper.getView(sql); and the List Adapter is: private static final String fields[] = {"Name"}; int[] names = new int[] {R.id.name}; SimpleCursorAdapter adapter2 = new SimpleCursorAdapter(this,R.layout.clientlist1, cdata, fields,names ); and the clientlist.xml is: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/MainLayout" android:padding="5px"> <TextView android:id="@+id/name" android:layout_alignParentRight="true" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="12sp" android:textColor="#104082" android:textStyle="bold" android:layout_weight="1" /> From this i am getting the list having the complete list having both parent and child list items in a single list view. I wish to differ in their text style(bold, normal) for parent and child items respectively. Please help me with the code/links. Thanks a lot in advance.

  • Python program to search for specific strings in hash values (coding help)

    - by Diego
    Trying to write a code that searches hash values for specific string's (input by user) and returns the hash if searchquery is present in that line. Doing this to kind of just learn python a bit more, but it could be a real world application used by an HR department to search a .csv resume database for specific words in each resume. I'd like this program to look through a .csv file that has three entries per line (id#;applicant name;resume text) I set it up so that it creates a hash, then created a string for the resume text hash entry, and am trying to use the .find() function to return the entire hash for each instance. What i'd like is if the word "gpa" is used as a search query and it is found in s['resumetext'] for three applicants(rows in .csv file), it prints the id, name, and resume for every row that has it.(All three applicants) As it is right now, my program prints the first row in the .csv file(print resume['id'], resume['name'], resume['resumetext']) no matter what the searchquery is, whether it's in the resumetext or not. lastly, are there better ways to doing this, by searching word documents, pdf's and .txt files in a folder for specific words using python (i've just started reading about the re module and am wondering if this may be the route, rather than putting everything in a .csv file.) def find_details(id2find): resumes_f=open("resume_data.csv") for each_line in resumes_f: s={} (s['id'], s['name'], s['resumetext']) = each_line.split(";") resumetext = str(s['resumetext']) if resumetext.find(id2find): return(s) else: print "No data matches your search query. Please try again" searchquery = raw_input("please enter your search term") resume = find_details(searchquery) if resume: print resume['id'], resume['name'], resume['resumetext']

  • How does the NY Times iPhone app do this?

    - by ArgMan
    Alright, I have an RSS feed that gets arranged in a UITableView and then the user selects a story and it loads in a UIWebView. However, I'd like to stop using the UIWebView and just use a UITextView or UILabel. This png is what I am trying to do (just display the various text aspects of a news story): http://img411.imageshack.us/img411/2449/screenshot20100315at120.png Let me start off by saying that I have tried to use the usualNSString *myText = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.textContent"]; and assign it to a UILabel, but it doesn't work the way that I am implementing it (in webViewDidFinishLoad--is that not correct?) and I get a blank textView and normal webView. If I overlay a UITextView on top of a UIWebView on its own (that is, a webView that just loads one page), the code posted above works fine to display the text I require, but the problem arises when the RSS feed is added into the mix. Ideas and/or help, guys? I've been stuck wondering why this doesn't work as it should for a few days now. If you have a better, more efficient way of doing it then placing the code in webViewDidFinishLoad, please let me know! Does it go in my didSelectRowAtIndexPath? I'm lost here, guys. Thank you very much in advance!

  • Parsing data from txt file in J2ME

    - by CSFYPMAIL
    Basically I'm creating an indoor navigation system in J2ME. I've put the location details in a .txt file i.e. Locations names and their coordinates. Edges with respective start node and end node as well as the weight (length of the node). I put both details in the same file so users dont have to download multiple files to get their map working (it could become time consuming and seem complex). So what i did is to seperate the deferent details by typing out location Names and coordinates first, After that I seperated that section from the next section which is the edges by drawing a line with multiple underscores. Now the problem I'm having is parsing the different details into seperate arrays by setting up a command (while manually tokenizing the input stream) to check wether the the next token is an underscore. If it is, (in pseudocode terms), move to the next line in the stream, create a new array and fill it up with the next set of details. I found a some explanation/code HERE that does something similar but still parses into one array, although it manually tokenizes the input. Any ideas on what to do? Thanks Text File Explanation The text has the following format... <--1stSection--  /**   * Section one has the following format   * xCoordinate;yCoordinate;LocationName   */ 12;13;New York City 40;12;Washington D.C. ...e.t.c _________________________ <--(underscore divider) <--2ndSection--  /**   * Its actually an adjacency list but indirectly provides "edge" details.   * Its in this form   * StartNode/MainReferencePoint;Endnode1;distance2endNode1;Endnode2;distance2endNode2;...e.t.c   */ philadelphia;Washington D.C.;7;New York City;2 New York City;Florida;24;Illinois;71 ...e.t.c

  • jquery carousel auto scroll with text and image

    - by Evan
    I'm using the jquery carousel and I have the image auto rotating here ( http://jsbin.com/unoce/2), so the issue I'm having is the content on the left is not AUTO rotating "with" the image and the arrow selection is not either. It only works when I click the content on the left and then the image on the right along with the arrow move appropriately together. Can someone provide support so I may get the text and the arrow to "auto" rotate with the image? This code below would only rotate the image and nothing else... jQuery(document).ready(function() { jQuery("#features").jcarousel({ scroll: 1, auto:2, wrap: 'both', initCallback: mycarousel_initCallback, buttonNextHTML: null, buttonPrevHTML: null }); }); Here's a demo and you can edit this demo too: http://jsbin.com/unoce/2 Thank you, Evan

  • Image map popup on rollover, with popup text drawn from database

    - by lbholland
    I have a custom map of the USA with about 20 polygonal hot spots. I would like a box to pop up next to each hot spot on hover, with text and links drawn from my DB specific to the location. I would have thought this is a common situation, but I can't find a solution that works. I tried using an asp:imagemap and an ajax popup extender but you can't assign IDs to hotspots and it doesn't support mouseover events. I tried css with an html image map but I can't figure out how to use css solutions with polygonal hot spots, and I also don't know how to link it to get the data from the db without asp targets (I'm not very familiar with jquery, which would work, I am guessing). Anyone know of any simple-ish solutions out there?

  • HTML5 Form Validation

    - by Stephen.Walther
    The latest versions of Google Chrome (16+), Mozilla Firefox (8+), and Internet Explorer (10+) all support HTML5 client-side validation. It is time to take HTML5 validation seriously. The purpose of the blog post is to describe how you can take advantage of HTML5 client-side validation regardless of the type of application that you are building. You learn how to use the HTML5 validation attributes, how to perform custom validation using the JavaScript validation constraint API, and how to simulate HTML5 validation on older browsers by taking advantage of a jQuery plugin. Finally, we discuss the security issues related to using client-side validation. Using Client-Side Validation Attributes The HTML5 specification discusses several attributes which you can use with INPUT elements to perform client-side validation including the required, pattern, min, max, step, and maxlength attributes. For example, you use the required attribute to require a user to enter a value for an INPUT element. The following form demonstrates how you can make the firstName and lastName form fields required: <!DOCTYPE html> <html > <head> <title>Required Demo</title> </head> <body> <form> <label> First Name: <input required title="First Name is Required!" /> </label> <label> Last Name: <input required title="Last Name is Required!" /> </label> <button>Register</button> </form> </body> </html> If you attempt to submit this form without entering a value for firstName or lastName then you get the validation error message: Notice that the value of the title attribute is used to display the validation error message “First Name is Required!”. The title attribute does not work this way with the current version of Firefox. If you want to display a custom validation error message with Firefox then you need to include an x-moz-errormessage attribute like this: <input required title="First Name is Required!" x-moz-errormessage="First Name is Required!" /> The pattern attribute enables you to validate the value of an INPUT element against a regular expression. For example, the following form includes a social security number field which includes a pattern attribute: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Pattern</title> </head> <body> <form> <label> Social Security Number: <input required pattern="^d{3}-d{2}-d{4}$" title="###-##-####" /> </label> <button>Register</button> </form> </body> </html> The regular expression in the form above requires the social security number to match the pattern ###-##-####: Notice that the input field includes both a pattern and a required validation attribute. If you don’t enter a value then the regular expression is never triggered. You need to include the required attribute to force a user to enter a value and cause the value to be validated against the regular expression. Custom Validation You can take advantage of the HTML5 constraint validation API to perform custom validation. You can perform any custom validation that you need. The only requirement is that you write a JavaScript function. For example, when booking a hotel room, you might want to validate that the Arrival Date is in the future instead of the past: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Constraint Validation API</title> </head> <body> <form> <label> Arrival Date: <input id="arrivalDate" type="date" required /> </label> <button>Submit Reservation</button> </form> <script type="text/javascript"> var arrivalDate = document.getElementById("arrivalDate"); arrivalDate.addEventListener("input", function() { var value = new Date(arrivalDate.value); if (value < new Date()) { arrivalDate.setCustomValidity("Arrival date must be after now!"); } else { arrivalDate.setCustomValidity(""); } }); </script> </body> </html> The form above contains an input field named arrivalDate. Entering a value into the arrivalDate field triggers the input event. The JavaScript code adds an event listener for the input event and checks whether the date entered is greater than the current date. If validation fails then the validation error message “Arrival date must be after now!” is assigned to the arrivalDate input field by calling the setCustomValidity() method of the validation constraint API. Otherwise, the validation error message is cleared by calling setCustomValidity() with an empty string. HTML5 Validation and Older Browsers But what about older browsers? For example, what about Apple Safari and versions of Microsoft Internet Explorer older than Internet Explorer 10? What the world really needs is a jQuery plugin which provides backwards compatibility for the HTML5 validation attributes. If a browser supports the HTML5 validation attributes then the plugin would do nothing. Otherwise, the plugin would add support for the attributes. Unfortunately, as far as I know, this plugin does not exist. I have not been able to find any plugin which supports both the required and pattern attributes for older browsers, but does not get in the way of these attributes in the case of newer browsers. There are several jQuery plugins which provide partial support for the HTML5 validation attributes including: · jQuery Validation — http://docs.jquery.com/Plugins/Validation · html5Form — http://www.matiasmancini.com.ar/jquery-plugin-ajax-form-validation-html5.html · h5Validate — http://ericleads.com/h5validate/ The jQuery Validation plugin – the most popular JavaScript validation library – supports the HTML5 required attribute, but it does not support the HTML5 pattern attribute. Likewise, the html5Form plugin does not support the pattern attribute. The h5Validate plugin provides the best support for the HTML5 validation attributes. The following page illustrates how this plugin supports both the required and pattern attributes: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>h5Validate</title> <style type="text/css"> .validationError { border: solid 2px red; } .validationValid { border: solid 2px green; } </style> </head> <body> <form id="customerForm"> <label> First Name: <input id="firstName" required /> </label> <label> Social Security Number: <input id="ssn" required pattern="^d{3}-d{2}-d{4}$" title="Expected pattern is ###-##-####" /> </label> <input type="submit" /> </form> <script type="text/javascript" src="Scripts/jquery-1.4.4.min.js"></script> <script type="text/javascript" src="Scripts/jquery.h5validate.js"></script> <script type="text/javascript"> // Enable h5Validate plugin $("#customerForm").h5Validate({ errorClass: "validationError", validClass: "validationValid" }); // Prevent form submission when errors $("#customerForm").submit(function (evt) { if ($("#customerForm").h5Validate("allValid") === false) { evt.preventDefault(); } }); </script> </body> </html> When an input field fails validation, the validationError CSS class is applied to the field and the field appears with a red border. When an input field passes validation, the validationValid CSS class is applied to the field and the field appears with a green border. From the perspective of HTML5 validation, the h5Validate plugin is the best of the plugins. It adds support for the required and pattern attributes to browsers which do not natively support these attributes such as IE9. However, this plugin does not include everything in my wish list for a perfect HTML5 validation plugin. Here’s my wish list for the perfect back compat HTML5 validation plugin: 1. The plugin would disable itself when used with a browser which natively supports HTML5 validation attributes. The plugin should not be too greedy – it should not handle validation when a browser could do the work itself. 2. The plugin should simulate the same user interface for displaying validation error messages as the user interface displayed by browsers which natively support HTML5 validation. Chrome, Firefox, and Internet Explorer all display validation errors in a popup. The perfect plugin would also display a popup. 3. Finally, the plugin would add support for the setCustomValidity() method and the other methods of the HTML5 validation constraint API. That way, you could implement custom validation in a standards compatible way and you would know that it worked across all browsers both old and new. Security It would be irresponsible of me to end this blog post without mentioning the issue of security. It is important to remember that any client-side validation — including HTML5 validation — can be bypassed. You should use client-side validation with the intention to create a better user experience. Client validation is great for providing a user with immediate feedback when the user is in the process of completing a form. However, client-side validation cannot prevent an evil hacker from submitting unexpected form data to your web server. You should always enforce your validation rules on the server. The only way to ensure that a required field has a value is to verify that the required field has a value on the server. The HTML5 required attribute does not guarantee anything. Summary The goal of this blog post was to describe the support for validation contained in the HTML5 standard. You learned how to use both the required and the pattern attributes in an HTML5 form. We also discussed how you can implement custom validation by taking advantage of the setCustomValidity() method. Finally, I discussed the available jQuery plugins for adding support for the HTM5 validation attributes to older browsers. Unfortunately, I am unaware of any jQuery plugin which provides a perfect solution to the problem of backwards compatibility.

  • Replace text in Word Document via ASP.NET

    - by jreedinc
    How can I replace a string/word in a Word Document via ASP.NET? I just need to replace a couple words in the document, so I would like to stay AWAY from 3rd party plugins & interop. I would like to do this by opening the file and replacing the text. The following attempts were made: I created a StreamReader and Writer to read the file but I think that I am reading and writing in the wrong format. I think that Word Documents are stored in binary?? If word documents are binary, how would I read and write the file in binary? Dim template As String = Request.MapPath("documentName.doc") If File.Exists(template) Then Dim sr As New StreamReader(template) Dim content As String = sr.ReadToEnd() sr.Close() Dim sw As New StreamWriter(template) content = content.Replace("@ T O D A Y S D A T E", Date.Now.ToString("MM/dd/yyyy")) sw.Write(content) sw.Close() Else

  • IPhone Plain TableView Section Header Image and Getting Text on Two Lines

    - by jp
    Hello, this is my first question, so if I didn't do the tags correctly, I'm sorry. I tried... Well here is my question: I am hoping someone can tell me how to do a 2-line section header for a plain tableview. The problems I am having are: 1) I cannot find an image that will mimic that of the default 1-line section header. Can someone share one with me, or tell me how I can find one? 2) I cannot seem to get the section header text on two lines, since I am pulling it from the fetched results controller, a "field" (sorry if wrong terminology) that I custom defined on the class for my table. So this "field" has multiple field values in it, and I have no way to take them apart... Any help would be appreciated.

  • Formatting text in an html table column?

    - by DavidR
    So, I have a table like below. Imagine there are multiple columns, I thought by formatting the <col/> tag I would be able to change the formatting of every <td> in that column. I want to give data in the first column a text-align:center, but it doesn't seem to work. Is there a way to get this to work other than adding a class to every <td>? <table> <col class="column"/> <tr> ... </tr> <tr> ... </tr> <tr> ... </tr> </table>

  • FlowDocument contents as text

    - by tyndall
    What is the best way to get back the XAML/XML value of a FlowDocument? I noticed there isn't a .Value, .Text, .Caption, .ToXml(), etc... UDPATE: I'd like to be able to get access to it initially to serialize to disk or database. Treat it as its own document format. Later translating it to other formats would be nice. Also been wondering: Any equivalent to a hyperlink (opens in new browser window) in a FlowDocument? Any workaround?
