  • Regular expression to convert ul to textindent and back, with a different attribute value for first

    - by chapmanio
    Hi, This is a related to a previous question I have asked here, see the link below for a brief description as to why I am trying to do this. Regular expression from font to span (size and colour) and back (VB.NET) Basically I need a regex replace function (or if this can be done in pure VB then that's fine) to convert all ul tags in a string to textindent tags, with a different attribute value for the first textindent tag. For example: <ul> <li>This is some text</li> <li>This is some more text</li> <li> <ul> <li>This is some indented text</li> <li>This is some more text</li> </ul> </li> <li>More text!</li> <li> <ul> <li>This is some indented text</li> <li>This is some more text</li> </ul> </li> <li>More text!</li> </ul> Will become: <textformat indent="0"> <li>This is some text</li> <li>This is some more text</li> <li> <textformat indent="20"> <li>This is some indented text</li> <li>This is some more text</li> </textformat> </li> <li>More text!</li> <li> <textformat indent="20"> <li>This is some indented text</li> <li>This is some more text</li> </textformat> </li> <li>More text!</li> </textformat> Basically I want the first ul tag to have no indenting, but all nested ul tags to have an indent of 20. I appreciate this is a strange request but hopefully that makes sense, please let me know if you have any questions. Thanks in advance.

  • Passing values from UIButton to an UIActionSheet

    - by Michael
    I'm trying to send an ActionSheet a variable from a button. I can't use the tag property because its being used for something else. I've declared myIndexRow as an instance variable and have: NSInteger myIndexRow = indexPath.row; [deleteButton addTarget:self action:@selector(showDeleteSheet:) forControlEvents:UIControlEventTouchUpInside]; deleteButton.myIndexRow = myIndexRow; but I'm getting the 'Request for member 'myRow' is something not a structure or union' There is something obvious I am missing here.

  • Converting contents of HtmlTextWriter to a string

    - by Tony_Henrich
    I have a third party tool that creates an img tag through code using HtmlTextWriter's RenderBeginTag, RenderEndTag & AddAttribute methods. I want to get the resulting HTML into a string. I tried the reflection method mentioned here but I get a error "Unable to cast object of type 'System.Web.HttpWriter' to type 'System.IO.StringWriter". The InnerWriter type of the HtmlTextWriter is of type HttpWriter. Any ideas on how to copy the output html into a string?

  • JavaScript tags, performance and W3C

    Today I was looking for website optimization content and I found an article talking about move JavaScript scripts to the bottom of the HTML page. Is this valid with W3C's recommendations? I learned that all JavaScript must be inside of head tag... Thank you.

  • HTTP Post requests using HttpClient take 2 seconds, why?

    - by pableu
    Update: You might better hold off this for a bit, I just noticed I could be my fault after all. Working on this all afternoon, and then I find a flaw ten minutes after posting here, ts. Hi, I'am currently coding an android app that submits stuff in the background using HTTP Post and AsyncTask. I use the org.apache.http.client Package for this. I based my code on this example. Basically, my code looks like this: public void postData() { // Create a new HttpClient and Post Header HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://192.168.1.137:8880/form"); try { List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); nameValuePairs.add(new BasicNameValuePair("id", "12345")); nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!")); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); // Execute HTTP Post Request HttpResponse response = httpclient.execute(httppost); } catch (ClientProtocolException e) { Log.e(TAG,e.toString()); } catch (IOException e) { Log.e(TAG,e.toString()); } } The problem is that the httpclient.execute(..) line takes around 1.5 to 3 seconds, and I do not understand why. Just requesting a page with HTTP Get takes around 80 ms or so, so the problem doesn't seem to be the network latency itself. The problem doesn't seem to be on the server side either, I have also tried POSTing data to http://www.disney.com/ with similarly slow results. And Firebug shows 1 ms response time when POSTing data to my server locally. This happens on the Emulator and with my Nexus One (both with Android 2.2). If you want to look at the complete code, I've put it on GitHub. It's just a dummy program to do HTTP Post in the background using AsyncTask on the push of a button. It's my first Android app, and my first java code for a long time. And incidentially, also my first question on Stackoverflow ;-) Any ideas why httpclient.execute(httppost) takes so long?

  • Getting all selected checkboxes values using ajax and jsp/servlets?

    - by A.S al-shammari
    Hi.. I'm developing a jsp/serlvet application. I have a page with a list of inputs as checkboxes . I want to send values of selected buttons to a servlet using ajax/jquery. In the servlet , I want to extract these values and use them . for example: The user checks some checkboxes , for example, list of messages. He/She presses Delete Link to delete selected messages. I searched and found something like this : $("#inboxDeleteSelected").click(function(){ var data = { 'checkBoxList[]' : []}; var list=$(":input:checkbox:checked"); // getting all selected checkboxes. $(list.each(function() { data['checkBoxList[]'].push($(this).val()); })); $.post("servlet?do=deleteSelected",data,function(d){ // do something here }); }); My questions: How can I send selected checkboxes values to a servlet ? How can I extract these values in the servlet ? Note: I don't use submit button to submit the selected checkboxes,Indeed I use link/anchor to send those values .

  • Unicode characters and IE

    - by findmeahamper
    I just built a site that relies on certain Unicode characters like &#9398;, but have just realized that IE doesn't show these characters? Is there some meta tag to get the browser to show it or how do you update IE to handle these Unicode characters?

  • Why is FLD1 loading NaN instead?

    I have a one-liner C function that is just return value * pow(1.+rate, -delay); - it discounts a future value to a present value.

Things get grossly over or undervalued, so even if there were no other bugs in my freeciv AI attempt, it would choose all the wrong strategies. Like sending the whole army to the arctic. (Sigh, if only I were getting that far.) I must be missing something obvious, or getting blinded by something, because I can't believe that fld1 should ever possibly fail. Even less that it should fail only after a handful of passes through this function. On earlier passes the FPU correctly loads 1 into ST(0). The bytes at 0x080555c6 definitely encode fld1 - checked with x/... on the running process. What gives?

  • Methodology for a Rails app

    - by Aaron Vegh
    I'm undertaking a rather large conversion from a legacy database-driven Windows app to a Rails app. Because of the large number of forms and database tables involved, I want to make sure I've got the right methodology before getting too far. My chief concern is minimizing the amount of code I have to write. There are many models that interact together, and I want to make sure I'm using them correctly. Here's a simplified set of models: class Patient < ActiveRecord::Base has_many :PatientAddresses has_many :PatientFileStatuses end class PatientAddress < ActiveRecord::Base belongs_to :Patient end class PatientFileStatus < ActiveRecord::Base belongs_to :Patient end The controller determines if there's a Patient selected; everything else is based on that. In the view, I will be needing data from each of these models. But it seems like I have to write an instance variable in my controller for every attribute that I want to use. So I start writing code like this: @patient = Patient.find(session[:patient]) @patient_addresses = @patient.PatientAddresses @patient_file_statuses = @patient.PatientFileStatuses @enrollment_received_when = @patient_file_statuses[0].EnrollmentReceivedWhen @consent_received = @patient_file_statuses[0].ConsentReceived @consent_received_when = @patient_file_statuses[0].ConsentReceivedWhen The first three lines grab the Patient model and its relations. The next three lines are examples of my providing values to the view from one of those relations. The view has a combination of text fields and select fields to show the data above. For example: <%= select("patientfilestatus", "ConsentReceived", {"val1"="val1", "val2"="val2", "Written"="Written"}, :include_blank=true )% <%= calendar_date_select_tag "patient_file_statuses[EnrollmentReceivedWhen]", @enrollment_complete_when, :popup=:force % (BTW, the select tag isn't really working; I think I have to use collection_select?) My questions are: Do I have to manually declare the value of every instance variable in the controller, or can/should I do it within the view? What is the proper technique for displaying a select tag for data that's not the primary model? When I go to save changes to this form, will I have to manually pick out the attributes for each model and save them individually? Or is there a way to name the fields such that ActiveRecord does the right thing? Thanks in advance, Aaron.

  • Changing background image of a Drupal page based on user's selection...?

    - by Sambo
    Hi I'm trying to give my users the functionality to change what the background image used on a page is. The list of background images will be a small number that won't really change. I thought I could add a few Taxonomy terms...one for each background type...then apply a class to the body tag when the page is viewed. Does this sound feasible and if so how would I go about doing it? Thanks Sam

  • ASP.net canvas server control

    - by Pierreten
    I was wondering if anyone has come up with an ASP.net server tag for the HTML5 canvas? I was thinking of something where I could declaritively define paths, curves; etc in the aspx markup, and the control would deliver the js to do this (perhaps with support for browser detection, and delivery of an emulation script for IE browsers.) Maybe a good idea for a Codeplex project for me to start up?

  • Grouped Select in Rails

    - by Neil Middleton
    Simple question really - how do I use the select(ActionView::Helpers::FormOptionsHelper) with grouped options? I have got it working with a select_tag (ActionView::Helpers::FormTagHelper) but I would really like to have it using a select tag to match the rest of the form. Is this possible? My options look like this: [ ['Group 1', ["Item 1", "Item 2", "Item 3"]], ['Group 2',["Item 1", "Item 2", "Item 3", "Item 4"]] ] whilst my view is currently: %tr#expense %td = f.text_field :value = f.hidden_field :type, :value => mode

  • How to set cursor at the end in a TEXTAREA? (by not using jQuery)

    - by Brian Hawk
    Is there a way to set the cursor at the end in a TEXTAREA tag? I'm using Firefox 3.6 and I don't need it to work in IE or Chrome. JavaScript is ok but it seems all the related answers in here use onfocus() event, which seems to be useless because when user clicks on anywhere within textarea, Firefox sets cursor position to there. I have a long text to display in a textarea so that it displays the last portion (making it easier to add something at the end).

  • Exception when creating an activity: Could not select item Parcel unable to marshal value

    - by user341652
    Hi, I am trying to call an Activity from another instance of the activity. The code is supposed to be a simple file browser (part of a larger application). I am using a ListActivity, and when an item (such as a folder) is selected, it is supposed to open it up in the new Activity. I have a feeling it is a problem with the AndroidManifest (which just has the basic tag). Any assistance would be appreciated. Thanks, Steve
