  • Javascript snippet to convert doxygen style comment to HTML

    - by Tobi
    In relation to this question, I was wondering if anyone knows a javascript code snippet/library to convert a single doxygen comment to HTML? For example, /** This is a comment block * * \b bold text * \i italic text */ would be converted to something like: <p>This is a comment block</p> <p><b>bold</b> text</p> <p><i>italic</i> text</p> Similar for all the other formatting related tags of doxygen. I've found this already, which seems to be a good starting point if I have to implement it myself, but possibly I'm missing a complete project :-) So, suggestions welcome!

  • Ambiguous Generic restriction T:class vs T:struct

    - by Maslow
    This code generates a compiler error that the member is already defined with the same parameter types. private T GetProperty<T>(Func<Settings, T> GetFunc) where T:class { try { return GetFunc(Properties.Settings.Default); } catch (Exception exception) { SettingReadException(this,exception); return null; } } private TNullable? GetProperty<TNullable>(Func<Settings, TNullable> GetFunc) where TNullable : struct { try { return GetFunc(Properties.Settings.Default); } catch (Exception ex) { SettingReadException(this, ex); return new Nullable<TNullable>(); } } Is there a clean work around?

  • New to asp.net. Need help debugging this email form.

    - by Roeland
    Hey guys, First of all, I am a php developer and most of .net is alien to me which is why I am posting here! I just migrated over a site from one set of webhosting to another. The whole site is written in .net. None of the site is database driven so most of it works, except for the contact form. The output on the site simple states there was an error with "There has been an error - please try to submit the contact form again, if you continue to experience problems, please notify our webmaster." This is just a simple message it pops out of it gets to the "catch" part of the email function. I went into web.config and changed the parameters: <emailaddresses> <add name="System" value="[email protected]"/> <add name="Contact" value="[email protected]"/> <add name="Info" value="[email protected]"/> </emailaddresses> <general> <add name="WebSiteDomain" value="hoyespharmacy.com"/> </general> Then the .cs file for contact contains the mail function EmailFormData(): private void EmailFormData() { try { StringBuilder body = new StringBuilder(); body.Append("Name" + ": " + txtName.Text + "\n\r"); body.Append("Phone" + ": " + txtPhone.Text + "\n\r"); body.Append("Email" + ": " + txtEmail.Text + "\n\r"); body.Append("Fax" + ": " + txtEmail.Text + "\n\r"); body.Append("Subject" + ": " + ddlSubject.SelectedValue + "\n\r"); body.Append("Message" + ": " + txtMessage.Text); MailMessage mail = new MailMessage(); mail.IsBodyHtml = false; mail.To.Add(new MailAddress(Settings.GetEmailAddress("System"))); mail.Subject = "Contact Us Form Submission"; mail.From = new MailAddress(Settings.GetEmailAddress("System"), Settings.WebSiteDomain); mail.Body = body.ToString(); SmtpClient smtpcl = new SmtpClient(); smtpcl.Send(mail); } catch { Utilities.RedirectPermanently(Request.Url.AbsolutePath + "?messageSent=false"); } } How do I see what the actual error is. I figure I can do something with the "catch" part of the function.. Any pointers? Thanks!

  • C# MessageBox Error Messages

    - by Jim Fell
    Hello. In my application I am using message boxes to display error information. try { // Something... } catch (SystemException ex) { MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); } This was fine at first, but as my program grows it becomes increasingly difficult to find the try-catch block where this error is generated. Is there a way to display the line of code or function in which the error was generated? I am using Microsoft Visual C# 2008 Express Edition. Thanks.

  • Workflow 4.0 code activities calling other activites (persist, delay etc)

    - by Lygpt
    I have a bunch of Workflow foundation 4.0 RC code activities that consume web services and talk to databases that I want to add some error handling in. I would really like to be able to attempt to call my web service / db, catch any faults such as a communication failure and then retry the same operation in 1 hours time (after I have logged the exception). Is there a way of doing something like this? protected override void Execute(CodeActivityContext context) { Persist(); // I would like to invoke the persist activity like this if (!AttemptServiceCall()) { // I would like to invoke a delay activity like this Delay(new TimeSpan(0, 30, 0)); // wait 30 mins before trying again Execute(context); // call this activity again } } private bool AttemptServiceCall() { bool serviceCallSuccessful = true; try { myService.InvokeSomeMethod(); } catch (CommunicationException ex) { myEventLogger.Log(ex); serviceCallSuccessful = false; } return serviceCallSuccessful; }

  • Change the order of the 'Search this site' form in Drupal

    - by Nick Lowman
    I need to change the layout of the Search Block in Drupal. It’s currently ordered Search Button ‘Search this site’ Search Input but the designs I have want it to be Search Input ‘Search this site’ Search Button How do I go around changing the order in Drupal? I can change the search-block-form.tpl.php so the submit button is at the end but the ‘Search this site’ always appears before the input and I would like it after. I hope that makes sense. I can also do it using CSS but I’d prefer to use Drupal? Many thanks in advance

  • Creating an image from webcam every x miliseconds

    - by Rita
    Hello everyone, I am using c# to integrate with a web cam. I need to generate a snapshot image every x miliseconds and save it to file. I already have the code up and running to save to file on a button click event, however I wonder what am I supposed to do when taking snapshots in the background - Should this be multi threaded? I'm honestly not sure. I could just block the UI thread, put Thread.Sleep and then just take the snapshot, but I don't know if this is right. I thought of using a background worker, but I am now experiencing cross threaded difficulties with SendMessage... So I wonder if I should even go and bother to multi-thread or just block the UI. Help greatly appertained, thanks in advance.

  • Strategies for Error Handling in .NET Web Services

    - by Jarrod
    I have a fairly substantial library of web services built in .NET that I use as a data model for our company web sites. In most .NET applications I use the Global ASAX file for profiling, logging, and creating bug reports for all exceptions thrown by the application. Global ASAX isn't available for web services so I'm curious as to what other strategies people have come up with to work around this limitation. Currently I just do something along these lines: <WebMethod()> _ Public Function MyServiceMethod(ByVal code As Integer) As String Try Return processCode(code) Catch ex As Exception CustomExHandler(ex) 'call a custom function every time to log exceptions Return errorObject End Try End Function Anybody have a better way of doing things besides calling a function inside the Catch?

  • Stop Images from loading in UIWebView

    - by Zac Altman
    I have a website that I wish to load in a UIWebView, but it is full of images and takes ages to load. The images are useless, and only serve to reduce the usability on the iPhone. I dont own the website so I cannot change the site's actual code. The webpage is heavily linked in to the web with ASP.NET and AJAX (needs external files), so i dont think it is possible to have it load an HTML string. I want to stop the images from loading altogether. So how do i block them? Change the HTML code as its loading somehow, or block images from being loaded?

  • Safari extension cookies not recognized/passed

    - by Alex
    I've recently been porting a Chrome extension to Safari, and encountered this kind of error (bug, feature, etc.) So, in global page i have a XMLHTTP request to a secure page which is available only after you login. Example: I simply login using browser - as usually you do on facebook or other secure pages After that, in global page, I load a login-only-available xmlhttp - and it says i'm not logged in it seems that global page somewhat has it's own cookies, so a secure page thinks i'm new ps: in Chrome i can load that page and it thinks i'm acting on behalf of logged in user, so i guess there are some restrictions in Safari pps: i heard there's a Block third-party cookies option in Safari, but even if i checked it to "Never block" it still doesn't work

    - by Zhen Le
    I have a MySQL database which contains data i would like to populate into a JList in my java program. I have two JList, one which is fill with Events Title and the second is to be fill with Guest Name. What i would like is when the user click on any of the Events Title, the second JList will show all the Guest Name that belong to that Event. I have already successfully populate the first JList with all the Events Title. What I'm having trouble with is when the user click on the Events Title, the Guests Name will show twice on the second JList. How can i make it to show only once? Here is what i got so far... Java Class private JList getJListEvents() { if (jListEvents == null) { jListEvents = new JList(); Border border = BorderFactory.createTitledBorder(BorderFactory.createBevelBorder(1, Color.black, Color.black), "Events", TitledBorder.LEFT, TitledBorder.TOP); jListEvents.setBorder(border); jListEvents.setModel(new DefaultListModel()); jListEvents.setBounds(new Rectangle(15, 60, 361, 421)); Events lEvents = new Events(); lEvents.loadEvents(jListEvents); jListEvents.addListSelectionListener(new ListSelectionListener(){ public void valueChanged(ListSelectionEvent e){ EventC eventC = new EventC(); //eventC.MonitorRegDetailsInfo(jListEvents, jTextFieldEventName, jTextFieldEventVenue, jTextFieldEventDate, jTextFieldEventTime, jTextAreaEventDesc); //eventC.MonitorRegPackageInfo(jListEvents, jTextFieldBallroom, jTextFieldBallroomPrice, jTextFieldMeal, jTextFieldMealPrice, jTextFieldEntertainment, jTextFieldEntertainmentPrice); eventC.MonitorRegGuest(jListEvents, jListGuest); } }); } return jListEvents; } Controller Class public void MonitorRegGuest(JList l, JList l2){ String event = l.getSelectedValue().toString(); Events retrieveGuest = new Events(event); retrieveGuest.loadGuests(l2); } Class with all the sql statement public void loadGuests(JList l){ ResultSet rs = null; ResultSet rs2 = null; ResultSet rs3 = null; MySQLController db = new MySQLController(); db.getConnection(); String sqlQuery = "SELECT MemberID FROM event WHERE EventName = '" + EventName + "'"; try { rs = db.readRequest(sqlQuery); while(rs.next()){ MemberID = rs.getString("MemberID"); } } catch (SQLException e) { e.printStackTrace(); } String sqlQuery2 = "SELECT GuestListID FROM guestlist WHERE MemberID = '" + MemberID + "'"; try { rs2 = db.readRequest(sqlQuery2); while(rs2.next()){ GuestListID = rs2.getString("GuestListID"); } } catch (SQLException e) { e.printStackTrace(); } String sqlQuery3 = "SELECT Name FROM guestcontact WHERE GuestListID = '" + GuestListID + "'"; try { rs3 = db.readRequest(sqlQuery3); while(rs3.next()){ ((DefaultListModel)l.getModel()).addElement(rs3.getString("Name")); } } catch (SQLException e) { e.printStackTrace(); } db.terminate(); } Thanks in advance!

  • Handling PHP exceptions with JQuery

    Hello, I'm using JQuery to call a PHP function that returns a JSON string upon success or throws some exceptions. Currently I'm calling jQuery.parseJSON() on the response and if it fails I assume the response contains an exception string. $.ajax({ type: "POST", url: "something.php", success: function(response){ try { var json = jQuery.parseJSON(response); } catch (e) { alert(response); return -1; } // ... do stuff with json } Can anyone suggest a more elegant way to catch the exception? Many thanks, Itamar
