  • BackgroundWorker Not working in VSTO

    - by Chris
    I have a background worker. Before I invoke the worker I disable a button and make a gif visible. I then invoke the runworkerasync method and it runs fine until comleteion. On the 'RunWorkerCompleted()' I get a cross thread error. Any idea why? private void buttonRun_Click(object sender, EventArgs e) { if (comboBoxFiscalYear.SelectedIndex != -1 && !string.IsNullOrEmpty(textBoxFolderLoc.Text)) { try { u = new UpdateDispositionReports( Convert.ToInt32(comboBoxFiscalYear.SelectedItem.ToString()) , textBoxFolderLoc.Text , Properties.Settings.Default.TemplatePath , Properties.Settings.Default.ConnStr); this.buttonRun.Enabled = false; this.pictureBox1.Visible = true; BackgroundWorker bw = new BackgroundWorker(); bw.DoWork += new DoWorkEventHandler(bw_DoWork); bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw_RunWorkerCompleted); bw.RunWorkerAsync(); //backgroundWorker1.RunWorkerAsync(); } catch (Exception ex) { MessageBox.Show("Unable to process.\nError:" + ex.Message, Properties.Settings.Default.AppName); } } } void bw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { buttonRun.Enabled = true; pictureBox1.Visible = false; } void bw_DoWork(object sender, DoWorkEventArgs e) { u.Execute(); }

  • Backend raising (INotify)PropertyChanged events to all connected clients?

    - by Jörg Battermann
    One of our 'frontend' developers keeps requesting from us backend developers that the backend notifies all connected clients (it's a client/server environment) of changes to objects. As in: whenever one user makes a change, all other connected clients must be notified immediately of the change. At the moment our architecture does not have a notification system of that kind and we don't have a sort of pub/sub model for explicitly chosen objects (e.g. the one the frontend is currently implementing).. which would make sense in such a usecase imho, but obviously requires extra implementation. However, I thought frontends typically check for locks for concurrently existing user changes on the same object and rather pull for changes / load on demand and in the background rather than the backend pushing all changes to all clients for all objects constantly.. which seems rather excessive to me. However, it's being argumented that e.g. the MS Entity Framework does in fact publish (INotify)PropertyChanged not only for local changes, but for all such changes including other client connections, but I have found no proof or details regarding this. Can anyone shed some light into this? Do other e.g. ORMs etc provide broadcasted (INotify)PropertyChanged events on entities?

  • running bash scripts in php

    - by HDawg
    I have two computers. On the first computer I have apache running with all my web code. On the second computer I have large amounts of data stored with a retrieval script (the script usually takes hours to run). I am essentially creating a web UI to access this data without any time delay. so I call: exec("bash initial.bash"); this is a driver script that is in my Apache folder. It calls the script on the other computer. calling: ssh otherMachine temp.bash& this script invokes the data retrieval script on the second computer. If I call initial.bash in the terminal, everything works smoothly and successfully, but if I call it in my PHP file, then all my commands in initial.bash run, with the exception of ssh otherMachine temp.bash&. I put the & at the end of that, so that temp.bash will run in the background, since it does take a few hours to complete. I am not sure why the nested script is not running when invoked by Apache. Is there a better alternative than using exec or shell_exec to call a script, which ultimately calls another script. The reason I don't call a script on the second machine directly is because of the time it takes the program to run. Shell_exec does not render the php page until the script is complete.

  • Using jQuery to grab the content from CKEditor's iframe

    - by miCRoSCoPiC_eaRthLinG
    Hey guys, I have this custom written CMS that uses CKEditor *(FCKEditor v3) for editing content. Along with that I'm using the jQuery Validation plugin to check all fields for error prior to ajax-based submission. For passing on the data to the PHP backend, I'm using the serialize() function. Problem is, serialize manages to grab all other fields correctly, except for the actual content typed in CKEditor. Like every other WYSIWYG editor, this one too overlays an iframe over an existing textbox. And serialize ignores the iframe and looks only into the textbox for content... which of course, it doesn't find - thus returning a blank content body. My approach to this is to create a hook onto the onchange event of CKEditor and concurrently update the textbox (CKEDITOR.instances.[textboxname].getData() returns the content) or some other hidden field with any changes made in the editor. However, since CKEditor is still in it's beta stage and severely lacks documentation, I cannot seem to find a suitable API call that'll enable me to do so. Does anyone have any idea on how to go about this? Or maybe suggest even a better method?

  • django customizing form labels

    - by Henri
    I have a problem in customizing labels in a Django form This is the form code in file contact_form.py: from django import forms class ContactForm(forms.Form): def __init__(self, subject_label="Subject", message_label="Message", email_label="Your email", cc_myself_label="Cc myself", *args, **kwargs): super(ContactForm, self).__init__(*args, **kwargs) self.fields['subject'].label = subject_label self.fields['message'].label = message_label self.fields['email'].label = email_label self.fields['cc_myself'].label = cc_myself_label subject = forms.CharField(widget=forms.TextInput(attrs={'size':'60'})) message = forms.CharField(widget=forms.Textarea(attrs={'rows':15, 'cols':80})) email = forms.EmailField(widget=forms.TextInput(attrs={'size':'60'})) cc_myself = forms.BooleanField(required=False) The view I am using this in looks like: def contact(request, product_id=None): . . . if request.method == 'POST': form = contact_form.ContactForm(request.POST) if form.is_valid(): . . else: form = contact_form.ContactForm( subject_label = "Subject", message_label = "Your Message", email_label = "Your email", cc_myself_label = "Cc myself") The strings used for initializing the labels will eventually be strings dependent on the language, i.e. English, Dutch, French etc. When I test the form the email is not sent and instead of the redirect-page the form returns with: <QueryDict: {u'cc_myself': [u'on'], u'message': [u'message body'], u'email':[u'[email protected]'], u'subject': [u'test message']}>: where the subject label was before. This is obviously a dictionary representing the form fields and their contents. When I change the file contact_form.py into: from django import forms class ContactForm(forms.Form): """ def __init__(self, subject_label="Subject", message_label="Message", email_label="Your email", cc_myself_label="Cc myself", *args, **kwargs): super(ContactForm, self).__init__(*args, **kwargs) self.fields['subject'].label = subject_label self.fields['message'].label = message_label self.fields['email'].label = email_label self.fields['cc_myself'].label = cc_myself_label """ subject = forms.CharField(widget=forms.TextInput(attrs={'size':'60'})) message = forms.CharField(widget=forms.Textarea(attrs={'rows':15, 'cols':80})) email = forms.EmailField(widget=forms.TextInput(attrs={'size':'60'})) cc_myself = forms.BooleanField(required=False) i.e. disabling the initialization then everything works. The form data is sent by email and the redirect page shows up. So obviously something the the init code isn't right. But what? I would really appreciate some help.

  • WCF Message Debugging on WebHttpBehavior

    - by Programming Hero
    I've created a custom binding in WCF for a custom MessageEncoder to allow messages to be written as XML using a wider range of encodings than WCF supports out of the box. The encoder appears to be working and I am able to send and receive messages, but I want to verify that the XML message being written is exactly as required by the service I am trying to consume. I've turned on message logging for WCF using the diagnostic trace listeners to output the messages sent and received over the wire to a log file. Unfortunately, for calls using my encoder, the message is displayed as ... stream ... EDIT: I don't think it's anything to do with my custom encoding. I have experimented with my custom binding a little, switching to using the built-in text encoding and http transport. I still don't get a message body logged in the message trace. EDIT2: Having done further investigation, the issue looks to be related not to the custom binding, but the custom behaviour. I'm apply the <webHttp/> behaviour. Once this is specified (along with manual addressing), the tracing behaviour shows up. Is this a known issue with WebHttpBehavior? Am I still barking up the wrong tree?

  • Format Java Code in Netbeans / Eclipse, but save it differently

    - by Walter White
    Hi all, I asked a related question before, but I guess the root of the question is. Let's say I have 2 developers on the team and they both like to look at code in different formats. One likes the braces to be on a new line and the other doesn't. The approach I was using before is that anytime we run a build, the code is automatically formatted according to the Java/Sun standards using Jalopy; however, I would like the developers to be as happy as possible. They can change the font size, font color, background color, etc. If I am currently using the Jalopy Maven plugin to format code, can/should I write a hook to SVN that calls mvn jalopy:format on the project when it's checked in? Is this reliable? That solution doesn't work 100% because it requires the developer to manually format the source code to their liking every time they open a file that hasn't been formatted yet. I was thinking an IDE plugin would be nice as it could automatically format the source to their liking and then save it as another. What other options do I have to ensure the code is formatted nicely on checkin? Thanks, Walter

  • How do you Access an Authenticated Google App Engine Service with Ruby?

    - by viatropos
    I am trying to do this same thing here but with Ruby: Access Authenticated GAE Client with Python. Any ideas how to retrieve authenticated content from GAE with Ruby? I am using the Ruby GData Gem to access everything in Google Docs and such and it's making life very easy, but now I'd like to access things on GAE that require admin access, programmatically, and it doesn't support that.

  • Building simple Reddit scraper

  • How to ellipsize center-aligned textview beside a right-aligned button when screen width is small

    - by simplymoody
    ------------------------------------ | LONG_TITL... |button| | |------------------------------------| | | I have an app header which consists of the app title and a button. The button should be fixed on the right side but I want the title to be in the middle and ellipsize when the screen is too small. Problem is the title just won't ellipsize even though the button is nearly beside it. Here's what I have so far: <RelativeLayout android:id="@+id/headr" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center"> <ImageView android:id="@+id/bar_orange" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:minHeight="40dp" android:scaleType="centerCrop" android:src="@drawable/bar_orange"/> <TextView android:id="@+id/Title" android:layout_marginLeft="20dp" android:layout_marginRight="20dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:gravity="center" android:text="@string/bcd" android:textColor="#FFFFFF" android:ellipsize="marquee" android:singleLine="true" android:textSize="18sp" android:textStyle="bold"/> <Button android:padding="5dp" android:id="@+id/home" android:textColor="#ffffff" android:layout_marginRight="10dp" android:layout_marginLeft="10dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:singleLine="true" android:background="@drawable/button_home" android:text="@string/home"/> </RelativeLayout> Is there a way to do this with just RelativeLayout?

  • CSS - Class hierarchies???

    - by ClarkeyBoy
    Hi, I have a site with a customer front end, which has a catalogue, homepage, contact page, about us page and so on. There is also an administration front end. I would like to implement a kind of hierarchy where any elements within an element with class "admin" will inherit properties set in the admin stylesheet and anything else inherits from the customer stylesheet. The purpose of this is so that admin can login on the admin front end, where they have access to lots of advanced stuff, but they can also navigate to the customer front end where they can execute basic tasks (such as hiding catalogue items, running a debug script if a customer reports an issue and so on). I would like all the admin tools on the customer front end to have properties taken from the admin stylesheet instead of the customer one - this will change the background colour and stuff. Is there any easy way to set up like namespaces to make things simpler, for example: .admin { .list { .list-subtitle { } .list-item { } } a { } } .customer { .list { .list-subtitle { } .list-item { } } a { } } I know it can be like: .admin .list {} .admin .list .list-item {} .admin a I just dont want to have to keep putting .admin all the time. Does anyone have any suggestions on how I could do this? I suppose I could write a .net class which sets this up and writes a stylesheet according to whats put into it, but then I would not be able to read the styles so easily add there would be all sorts of like Classes.Add(blah) and so on. Thanks in advance for any replies... Regards, Richard

  • ASP.NET MVC and WCF

    - by Michael Stum
    I'm working my way into MVC at the moment, but on my "To learn at some point" list, I also have WCF. I just wonder if WCF is something that should/could be used in an MVC Application or not? The Background is that I want a Desktop Application (.NET 3.5, WPF) interact with my MVC Web Site, and I wonder what the best way to transfer data between the two is. Should I just use special Views/have the controllers return JSON or XML (using the ContentResult)? And maybe even more important, for the other way round, could I just call special controllers? Not sure how Authorization would work in such a context. I can either use Windows Authentication or (if the Site is running forms authentication) have the user store his/her credentials in the application, but I would then essentially create a HTTP Client in my Application. So while MVC = Application seems really easy, Application = MVC does seem to be somewhat tricky and a possible use for WCF? I'm not trying to brute-force WCF in this, but I just wonder if there is indeed a good use case for WCF in an MVC application.

  • Delegate within a delegate in VB.NET.

    - by Topdown
    I am trying to write a VB.NET alternative to a C# anonymous function. I wish to call Threading.SynchronizationContext.Current.Send which expects a delegate of type Threading.SendOrPostCallback to be passed to it. The background is here, but because I wish to both pass in a string to MessageBox.Show and also capture the DialogResult I need to define another delegate within. I am struggling with the VB.NET syntax, both from the traditional delegate style, and lambda functions. My go at the traditional syntax is below, but I have gut feeling it should be much simpler than this: Private Sub CollectMesssageBoxResultFromUserAsDelegate(ByVal messageToShow As String, ByRef wasCanceled As Boolean) wasCanceled = False If Windows.Forms.MessageBox.Show(String.Format("{0}{1}Please press [OK] to ignore this error and continue, or [Cancel] to stop here.", messageToShow), "Continue", Windows.Forms.MessageBoxButtons.OKCancel, Windows.Forms.MessageBoxIcon.Exclamation) = Windows.Forms.DialogResult.Cancel Then wasCanceled = True End If End Sub Private Delegate Sub ShowMessageBox(ByVal messageToShow As String, ByRef canceled As Boolean) Private Sub AskUserWhetherToCancel(ByVal message As String, ByVal args As CancelEventArgs) If args Is Nothing Then args = New System.ComponentModel.CancelEventArgs With {.Cancel = False} Dim wasCancelClicked As Boolean Dim firstDelegate As New ShowMessageBox(AddressOf CollectMesssageBoxResultFromUserAsDelegate) '…. Now what?? 'I can’t declare SendOrPostCallback as below: 'Dim myDelegate As New Threading.SendOrPostCallback(AddressOf firstDelegate) End Sub

  • WinForms Load Event / Static Initialization Strangeness

    - by Eric J.
    Background I'm troubleshooting an WinForms 2.0 program that's already been burned to CD for distribution to an internet-challenged target audience. Some users are experiencing a fatal error that I can reproduce locally. Reproducing the Error I get the fatal error when I log into my Vista box using a standard user that I just created, even if I run the program as administrator. I do not get the fatal error when I log in as local administrator. I'm not sure that being administrator is necessarily the trigger (since runas did not help). I have reproduced this half a dozen times under each account with consistent results. The faulty code Base.cs (base class for several user controls, only one of which is shown on first screen) private void BaseWindow_Load(object sender, EventArgs e) { // This message shown once in both cases MessageBox.Show("BaseWindow_Load for " + this.GetType().FullName); SkinManager.ApplySkin(this); } SkinManager.cs private static Skin skin = null; public static void ApplySkin(UserControl applyTo) { if (skin == null) { skin = new Skin(SkinsDirectory, "Default"); } } Skin.cs internal Skin(string skinPath, string skinName) { config = SkinConfig.Load(path); } SkinConfig.cs public static SkinConfig Load(string path) { // This message shown only once running as Admin but twice running as standard user System.Windows.Forms.MessageBox.Show("@1"); // !!! LOCK path HERE !!! } A user control loads on the first form, which triggers a call to SkinManager.ApplySkin, which checks if skin is null and, if so assigns it (without thread synchronization or recursion protection), which ultimately causes a file to be opened. When logged in as local admin, that sequence completes just fine. When logged in as my test standard user, ApplySkin is always called a second time while skin is still null, causing a second attempt to load, causing the file to be locked on the second attempt. The error handling is draconian at this point and the program terminates. The Question While this code can be easily fixed, I would like to understand why the error is happening only in some cases.

  • Pros and cons of making database IDs consistent and "readable"

    - by gmale
    Question Is it a good rule of thumb for database IDs to be "meaningless?" Conversely, are there significant benefits from having IDs structured in a way where they can be recognized at a glance? What are the pros and cons? Background I just had a debate with my coworkers about the consistency of the IDs in our database. We have a data-driven application that leverages spring so that we rarely ever have to change code. That means, if there's a problem, a data change is usually the solution. My argument was that by making IDs consistent and readable, we save ourselves significant time and headaches, long term. Once the IDs are set, they don't have to change often and if done right, future changes won't be difficult. My coworkers position was that IDs should never matter. Encoding information into the ID violates DB design policies and keeping them orderly requires extra work that, "we don't have time for." I can't find anything online to support either position. So I'm turning to all the gurus here at SA! Example Imagine this simplified list of database records representing food in a grocery store, the first set represents data that has meaning encoded in the IDs, while the second does not: ID's with meaning: Type 1 Fruit 2 Veggie Product 101 Apple 102 Banana 103 Orange 201 Lettuce 202 Onion 203 Carrot Location 41 Aisle four top shelf 42 Aisle four bottom shelf 51 Aisle five top shelf 52 Aisle five bottom shelf ProductLocation 10141 Apple on aisle four top shelf 10241 Banana on aisle four top shelf //just by reading the ids, it's easy to recongnize that these are both Fruit on Aisle 4 ID's without meaning: Type 1 Fruit 2 Veggie Product 1 Apple 2 Banana 3 Orange 4 Lettuce 5 Onion 6 Carrot Location 1 Aisle four top shelf 2 Aisle four bottom shelf 3 Aisle five top shelf 4 Aisle five bottom shelf ProductLocation 1 Apple on aisle four top shelf 2 Banana on aisle four top shelf //given the IDs, it's harder to see that these are both fruit on aisle 4 Summary What are the pros and cons of keeping IDs readable and consistent? Which approach do you generally prefer and why? Is there an accepted industry best-practice?

  • SmtpClient.SendAsync - How to ensure my application doesn't finish before callback?

    - by James
    Hi, I need to send emails asychronously through a console application. I need to do some DB updates on the callback but my application is exiting before the callback code gets run! How can I stop this from happening in a nice manner rather than simply guessing how long to wait before exiting. I would imagine the Async calls get placed in some form of thread? Is it possible to check if any are waiting to be called? Sample Code private static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e) { // Get the unique identifier for this asynchronous operation. String token = (string) e.UserState; if (e.Cancelled) { Console.WriteLine("[{0}] Send canceled.", token); } if (e.Error != null) { Console.WriteLine("[{0}] {1}", token, e.Error.ToString()); } else { // update DB Console.WriteLine("Message sent."); } } public static void Main(string[] args) { var users = Repository.GetUsers(); SmtpClient client = new SmtpClient("Host"); client.SendCompleted += new SendCompletedEventHandler(SendCompletedCallback); MailAddress from = new MailAddress("[email protected]", "System", Encoding.UTF8); foreach (var user in users) { MailAddress to = new MailAddress(user.Email); MailMessage message = new MailMessage(from, to); message.Body = "This is a test"; message.BodyEncoding = System.Text.Encoding.UTF8; message.Subject = "test message 1" + someArrows; message.SubjectEncoding = System.Text.Encoding.UTF8; string userState = String.Format("Message for user id {0}", user.ID); client.SendAsync(message, userState); message.Dispose(); } // need to wait here until I have received a callback for each message // otherwise the application will exit }

  • How do you pass .net objects values around in F#?

    - by Russell
    I am currently learning F# and functional programming in general (from a C# background) and I have a question about using .net CLR objects during my processing. The best way to describe my problem will be to give an example: let xml = new XmlDocument() |> fun doc -> doc.Load("report.xml"); doc let xsl = new XslCompiledTransform() |> fun doc -> doc.Load("report.xsl"); doc let transformedXml = new MemoryStream() |> fun mem -> xsl.Transform(xml.CreateNavigator(), null, mem); mem This code transforms an XML document with an XSLT document using .net objects. Note XslCompiledTransform.Load works on an object, and returns void. Also the XslCompiledTransform.Transform requires a memorystream object and returns void. The above strategy used is to add the object at the end (the ; mem) to return a value and make functional programming work. When we want to do this one after another we have a function on each line with a return value at the end: let myFunc = new XmlDocument("doc") |> fun a -> a.Load("report.xml"); a |> fun a -> a.AppendChild(new XmlElement("Happy")); a Is there a more correct way (in terms of functional programming) to handle .net objects and objects that were created in a more OO environment? The way I returned the value at the end then had inline functions everywhere feels a bit like a hack and not the correct way to do this. Any help is greatly appreciated!

  • What is the proper way to handle non-tracking self tracking entities?

    - by Will
    Self tracking entities. Awesome. Except when you do something like return Db.Users; none of the self-tracking entities are tracking (until, possibly, they are deserialized). Fine. So we have to recognize that there is a possibility that an entity returning to us does not have tracking enabled. Now what??? Things I have tried For the given method body: using (var db = new Database()) { if (update.ChangeTracker.ChangeTrackingEnabled) db.Configurations.ApplyChanges(update); else FigureItOut(update, db); db.SaveChanges(); update.AcceptChanges(); } The following implementations of FigureItOut all fail: db.Configurations.Attach(update); db.DetectChanges(); Nor db.Configurations.Attach(update); db.Configurations.ApplyCurrentValues(update); Nor db.Configurations.Attach(update); db.Configurations.ApplyOriginalValues(update); Nor db.Configurations.Attach(update); db.Configurations.ApplyChanges(update Nor about anything else I can figure to throw at it, other than Getting the original entity from the database Comparing each property by hand Updating properties as needed What, exactly, am I supposed to do with self-tracking entities that aren't tracking themselves??

  • Performance problem with System.Net.Mail

    - by Saif Khan
    I have this unusual problem with mailing from my app. At first it wasn't working (getting unable to relay error crap) anyways I added the proper authentication and it works. My problem now is, if I try to send around 300 emails (each with a 500k attachment) the app starts hanging around 95% thru the process. Here is some of my code which is called for each mail to be sent Using mail As New MailMessage() With mail .From = New MailAddress(My.Resources.EmailFrom) For Each contact As Contact In Contacts .To.Add(contact.Email) Next .Subject = "Accounting" .Body = My.Resources.EmailBody 'Back the stream up to the beginning orelse the attachment 'will be sent as a zero (0) byte file. attachment.Seek(0, SeekOrigin.Begin) .Attachments.Add(New Attachment(attachment, String.Concat(Item.Year, Item.AttachmentType.Extension))) End With Dim smtp As New SmtpClient("192.168.1.2") With smtp .DeliveryMethod = SmtpDeliveryMethod.Network .UseDefaultCredentials = False .Credentials = New NetworkCredential("username", "password") .Send(mail) End With End Using With item .SentStatus = True .DateSent = DateTime.Now.Date .Save() End With Return I was thinking, can I just prepare all the mails and add them to a collection then open one SMTP conenction and just iterate the collection, calling the send like this Using mail As New MailMessage() ... MailCollection.Add(mail) End Using ... Dim smtp As New SmtpClient("192.168.1.2") With smtp .DeliveryMethod = SmtpDeliveryMethod.Network .UseDefaultCredentials = False .Credentials = New NetworkCredential("username", "password") For Each mail in MainCollection .Send(mail) Next End With

  • R: dev.copy2pdf, multiple graphic devices to a single file, how to append to file?

    - by Timtico
    Hi everybody, I have a script that makes barplots, and opens a new window when 6 barplots have been written to the screen and keeps opening new graphic devices whenever necessary. Depending on the input, this leaves me with a potential large number of openened windows (graphic devices) which I would like to write to a single PDF file. Considering my Perl background, I decided to iterate over the different graphics devices, printing them out one by one. I would like to keep appending to a single PDF file, but I do not know how to do this, or if this is even possible. I would like to avoid looping in R. :) The code I use: for (i in 1:length(dev.list()) { dev.set(which = dev.list()[i] dev.copy2pdf(device = quartz, file = "/Users/Tim/Desktop/R/Filename.pdf") } However, this is not working as it will overwrite the file each time. Now is there an append function in R, like there is in Perl. Which allows me to keep adding pages to the existing pdf file? Or is there a way to contain the information in a graphic window to a object, and keep adding new graphic devices to this object and finally print the whole thing to a file? Other possible solutions I thought about: writing different pdf files, combining them after creation (perhaps even possible in R, with the right libraries installed?) copying the information in all different windows to one big graphic device and then print this to a pdf file.

  • ruby nl2br outside <code> ... </code>

    - by Julien P.
    Hi everyone, I've been struggling on this thing for a week without being able to find what I'm looking for. Here is what I'd like to do: I'm setting up a wiki where I can post all my knowledge to (yes, I know a couple things :p) but I can't render it the way I'd like to. The bodies of my posts are text fields. In order to render them the right way I run the following command: @post.body.gsub("\n", "<br />") I also have some tags with some code inside that looks like this < code my code < /code. Here come's the issue. Every line between the < code and < /code tags are changed to but it doesn'r render properly since I'm using a code render template. Therefore, I'd like to know if there is a way to change all \n to < br / except for those between < code and < /code Thank you everyone for reading this and helping me out. PS: Please do not consider the spaces after the < in each tag. I had to do this to "espace" them. Julien

  • CSS selector involving pseudo class first-child and dropcap

    - by Grnbeagle
    Hi, I need to format HTML similar to below. Basically a quote is optional, and I need to dropcap the first letter of the body paragraph. <article> <p class="quote"> <!-- quote is optional --> Genius begins great works; labor alone finishes them.-- Joseph Joubert </p> <p> <!-- "L" is a dropcap --> Life is like a box of chocolates. </p> <p>...</p> <p>...</p> </article> My CSS looks like this: article > p:first-child:first-letter { float: left; font-family: Georgia, serif; font-size: 360%; line-height: 0.85em; margin-right: 0.05em; } p.quote { font-weight: bold; } It doesn't work currently when the quote is introduced. AFAIK I can't select the article's first child P which is not class "quote." I'll use jQuery if I can't figure this out, but for now I'm looking for a way to do it CSS only. Thanks in advance!

  • Before data is entered, is there a way to make a grouped table graphic placeholder?

    - by Matt Winters
    I have a grouped table with 3 sections, each section with a title. The 1st and 3rd sections always have only 1 row of information so before any user data is entered, I just put some words like "Enter Data Here..." as placeholder text. This text is edited (replaced) by the user with their own actual data. No problem. The 2nd section however will contain several rows of information entered by user and I'd prefer not to enter placeholder data in row 0, having the user Edit the first row of data then Add subsequent rows. If the numberOfRowsInSection is set to 0, the title for the 3rd section comes close to the title for the 2nd section and it looks ugly. The best that I could come with, and I don't know to do it, is to have a fake graphic placeholder on the striped background (between the 2nd and third titles) that looks like a single row in the 2nd section, put "Enter Data Here..." text in the graphic, and then the first row of actual data entered and all subsequent rows will cover it up. Can anyone tell me how to do this or offer a better suggestion. Thanks.

  • A problem of trying to implement scrolling inertia with jQuery

    - by gargantaun
    I'm trying to add some iPhone style scrolling inertia to a web page that will only be viewed on the iPad. I have the scrolling working in one direction (scrollLeft), but it doesn't work in the other direction. It's a pretty simple function function onTouchEnd(event){ event.preventDefault(); inertia = (oldMoveX - touchMoveX); // Inertia Stuff if( Math.abs(inertia) > 10 ){ $("#feedback").html(inertia); $("#container").animate({ 'scrollLeft': $("#container").scrollLeft() + (inertia * 10) }, inertia * 20); }else{ $("#feedback").html("No Inertia"); } } I've bound it to the 'touchend' event on the body. The intertia is the difference betweent he old moveX position and the latest moveX position when a touch ends. I then try to animate the scrollLeft property of a div that contains a bunch of thumbnails. As I've said, this works when scrolling to the left, but not when scrolling to the right. You can view the full source code (all in one page) or test it on your iPhone or iPad (or in the simulator) here http://www.appliedworks.co.uk/files/times/swipegal.html Any ideas?
