  • Dynamically generate PDF and email it using django

    - by Shane
    I have a django app that dynamically generates a PDF (using reportlab + pypdf) from user input on an HTML form, and returns the HTTP response with an application/pdf MIMEType. I want to have the option between doing the above, or emailing the generated pdf, but I cannot figure out how to use the EmailMessage class's attach(filename=None, content=None, mimetype=None) method. The documentation doesn't give much of a description of what kind of object content is supposed to be. I've tried a file object and the above application/pdf HTTP response. I currently have a workaround where my view saves a pdf to disk, and then I attach the resulting file to an outgoing email using the attach_file() method. This seems wrong to me, and I'm pretty sure there is a better way.

  • Retrieve EF4 POCOs using WCF REST services starter kit

    - by muruge
    I am using WCF REST service (GET method) to retrieve my EF4 POCOs. The service seem to work just fine. When I query the uri in my browser I get the results as expected. In my client application I am trying to use WCF REST Starter Kit's HTTPExtension method - ReadAsDataContract() to convert the result back into my POCO. This works fine when the POCO's navigation property is a single object of related POCO. The problem is when the navigation property is a collection of related POCOs. The ReadAsDataContract() method throws an exception with message "Object reference not set to an instance of an object." Below are my POCOs. [DataContract(Namespace = "", Name = "Trip")] public class Trip { [DataMember(Order = 1)] public virtual int TripID { get; set; } [DataMember(Order = 2)] public virtual int RegionID { get; set; } [DataMember(Order = 3)] public virtual System.DateTime BookingDate { get; set; } [DataMember(Order = 4)] public virtual Region Region { // removed for brevity } } [DataContract(Namespace = "", Name = "Region")] public class Region { [DataMember(Order = 1)] public virtual int RegionID { get; set; } [DataMember(Order = 2)] public virtual string RegionCode { get; set; } [DataMember(Order = 3)] public virtual FixupCollection<Trip> Trips { // removed for brevity } } [CollectionDataContract(Namespace = "", Name = "{0}s", ItemName = "{0}")] [Serializable] public class FixupCollection<T> : ObservableCollection<T> { protected override void ClearItems() { new List<T>(this).ForEach(t => Remove(t)); } protected override void InsertItem(int index, T item) { if (!this.Contains(item)) { base.InsertItem(index, item); } } } And this is how I am trying retrieve a Region POCO. static void GetRegion() { string uri = "http://localhost:8080/TripService/Regions?id=1"; HttpClient client = new HttpClient(uri); using (HttpResponseMessage response = client.Get(uri)) { Region region; response.EnsureStatusIsSuccessful(); try { region = response.Content.ReadAsDataContract<Region>(); // this line throws exception because Region returns a collection of related trips Console.WriteLine(region.RegionName); } catch (Exception ex) { Console.WriteLine(ex.Message); } } } Would appreciate any pointers.

  • how to change a button into a imagebutton in asp.net c#

  • How do you get AOL's OpenID site verification to work?

    I have an OpenID relying party setup and using XRDS. It passes the "RP has discoverable return_to" interop test over at http://test-id.org/RP/DiscoverableReturnTo.aspx. Yahoo no longer complains with the message "Warning: This website has not confirmed its identity with Yahoo! and might be fraudulent." as outlined in Andrew Arnott's excellent blog post: http://blog.nerdbank.net/2008/06/why-yahoo-says-your-openid-site.html However, when I try to authenticate using AOL I see the "Warning! site verification could not be completed." message.

  • Custom Control Not Playing Nice With PropertyGrid

    - by lumberjack4
    I have a class that is implementing a custom ToolStripItem. Everything seems to work great until I try to add the item to a ContextMenuStrip at design time. If I try to add my custom control straight from the ContextMenuStrip the PropertyGrid freezes up and will not let me modify my Checked or Text properties. But if I go into the ContextMenuStrip PropertyGrid and add my custom control through the Items(...) property, I can modify the custom control just fine within that dialog. I'm not sure if I'm missing an attribute somewhere of if its a problem with the underlying code. Here is a copy of the CustomToolStripItem class. As you can see, its a very simple class. [ToolStripItemDesignerAvailability(ToolStripItemDesignerAvailability.ContextMenuStrip)] public class CustomToolStripItem : ToolStripControlHost { #region Public Properties [Description("Gets or sets a value indicating whether the object is in the checked state")] [ReadOnly(false)] public bool Checked { get { return checkBox.Checked; } set { checkBox.Checked = value; } } [Description("Gets or sets the object's text")] [ReadOnly(false)] public override string Text { get { return checkBox.Text; } set { checkBox.Text = value; } } #endregion Public Properties #region Public Events public event EventHandler CheckedChanged; #endregion Public Events #region Constructors public CustomToolStripItem() : base(new FlowLayoutPanel()) { // Setup the FlowLayoutPanel. controlPanel = (FlowLayoutPanel)base.Control; controlPanel.BackColor = Color.Transparent; // Add the child controls. checkBox.AutoSize = true; controlPanel.Controls.Add(checkBox); ContextMenuStrip strip = new ContextMenuStrip(); } #endregion Constructors #region Protected Methods protected override void OnSubscribeControlEvents(Control control) { base.OnSubscribeControlEvents(control); checkBox.CheckedChanged += new EventHandler(CheckChanged); } protected override void OnUnsubscribeControlEvents(Control control) { base.OnUnsubscribeControlEvents(control); checkBox.CheckedChanged -= new EventHandler(CheckChanged); } #endregion Protected Methods #region Private Methods private void CheckChanged(object sender, EventArgs e) { // Throw the CustomToolStripItem's CheckedChanged event EventHandler handler = CheckedChanged; if (handler != null) { handler(sender, e); } } #endregion Private Methods #region Private Fields private FlowLayoutPanel controlPanel; private CheckBox checkBox = new CheckBox(); #endregion Private Fields }

  • Javassist: how to create proxy of proxy?

    - by Bozho
    I'm creating proxies with javassist ProxyFactory. When creating a single proxy all works fine. However, when I pass a proxied class to the proxying mechanism, it fails with javassist.bytecode.DuplicateMemberException: duplicate method: setHandler in com.mypackage.Bean_$$_javassist_0_$$_javassist_1 I'm creating the proxies with this: public Object createProxiedInstance(Object originalInstance) throws Exception { Class<?> originalClass = instance.getClass(); ProxyFactory factory = new ProxyFactory(); factory.setSuperclass(originalClass); factory.setHandler(new MethodHandler() {..}); Class<T> proxyClass = factory.createClass(); return proxyClass.newInstance(); } So, how do I create proxies of proxies? Update: The actual problems is that each proxy implements the ProxyObject which defines setHandler(..) method. So the 2nd proxy is trying to redefine the method, instead of overriding it in the subclass.

  • Good example usage of get_or _create in Django views and raising a Form error

    - by Rik Wade
    I would like to use get_or_create to check whether an object already exists in my database. If it does not, then it will be created. If it does exist, then I will not create the new object, but need to raise a form error to inform the user that they need to enter different data (for example, a different username). The view contains: p, created = Person.objects.get_or_create( email = registration_form.cleaned_data['email'], defaults = { 'creationDate': datetime.datetime.now(), 'dateOfBirth': datetime.date(1970,1,1) }) So 'p' will contain the existing Person if it exists, or the new Person if not. I would like to act on the boolean value in 'created' in order to skip over saving the Person and re-display the registration_form and raise an appropriate form validation error. The alternative I'm considering is doing a check in a custom Form validation method to see whether a Person exists with the data in the provided 'email' field, and just raising a validation error.

  • Why is UIApplicationWillChangeStatusBarFrameNotification not sent when the in-call status bar is sho

    - by Sbrocket
    I've been trying to listen for changes in the status bar height – such as when the in-call status bar is shown or hidden – by listening for the UIApplicationWillChangeStatusBarFrameNotification notification to be sent. Fairly straightforward code here... [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(statusBarWillChangeFrame:) name:UIApplicationWillChangeStatusBarFrameNotification object:nil]; But the notification never seems to be sent in that case, either on the Simulator by using the "Toggle In-Call Status Bar" option or on the device when a call ends with the application open. In addition, the similar UIApplicationDelegate method is not called. According to the documentation, UIApplicationWillChangeStatusBarFrameNotification Posted when the application is about to change the frame of the status bar. The userInfo dictionary contains an NSValue object that encapsulates a CGRect structure expressing the location and size of the new status bar frame. Use UIApplicationStatusBarFrameUserInfoKey to access this value. Can anyone explain why this notification is not being sent in response to the in-call status bar being shown or hidden? According to the documentation, it should be.

  • How to embed PDF in a web page using Acrobat Reader instead of Acrobat.

    I have a pdf form that uses Acrobat 8 features. The form contains Javascript that interacts with the hosting web page. Some of my Windows users have both Adobe Acrobat and Acrobat Reader installed, and need Adobe Acrobat to be the default handler for pdf files. The users with Adobe Acrobat 7 are unable to use the form, even though they might have Acrobat Reader 8 or 9 installed. Currently, the PDF is embedded like this: <object id="host" data="/path/to/document.pdf" type="application/pdf" width="900" height="550" ></object>

  • Linq query challenge

    - by vdh_ant
    My table structure is as follows: Person 1-M PesonAddress Person 1-M PesonPhone Person 1-M PesonEmail Person 1-M Contract Contract M-M Program Contract M-1 Organization At the end of this query I need a populated object graph where each person has their: PesonAddress's PesonPhone's PesonEmail's PesonPhone's Contract's - and this has its respective Program's Now I had the following query and I thought that it was working great, but it has a couple of problems: from people in ctx.People.Include("PersonAddress") .Include("PersonLandline") .Include("PersonMobile") .Include("PersonEmail") .Include("Contract") .Include("Contract.Program") where people.Contract.Any( contract => (param.OrganizationId == contract.OrganizationId) && contract.Program.Any( contractProgram => (param.ProgramId == contractProgram.ProgramId))) select people; The problem is that it filters the person to the criteria but not the Contracts or the Contract's Programs. It brings back all Contracts that each person has not just the ones that have an OrganizationId of x and the same goes for each of those Contract's Programs respectively. What I want is only the people that have at least one contract with an OrgId of x with and where that contract has a Program with the Id of y... and for the object graph that is returned to have only the contracts that match and programs within that contract that match. I kinda understand why its not working, but I don't know how to change it so it is working... This is my attempt thus far: from people in ctx.People.Include("PersonAddress") .Include("PersonLandline") .Include("PersonMobile") .Include("PersonEmail") .Include("Contract") .Include("Contract.Program") let currentContracts = from contract in people.Contract where (param.OrganizationId == contract.OrganizationId) select contract let currentContractPrograms = from contractProgram in currentContracts let temp = from x in contractProgram.Program where (param.ProgramId == contractProgram.ProgramId) select x where temp.Any() select temp where currentContracts.Any() && currentContractPrograms.Any() select new Person { PersonId = people.PersonId, FirstName = people.FirstName, ..., ...., MiddleName = people.MiddleName, Surname = people.Surname, ..., ...., Gender = people.Gender, DateOfBirth = people.DateOfBirth, ..., ...., Contract = currentContracts, ... }; //This doesn't work But this has several problems (where the Person type is an EF object): I am left to do the mapping by myself, which in this case there is quite a lot to map When ever I try to map a list to a property (i.e. Scholarship = currentScholarships) it says I can't because IEnumerable is trying to be cast to EntityCollection Include doesn't work Hence how do I get this to work. Keeping in mind that I am trying to do this as a compiled query so I think that means anonymous types are out.

  • Rails - embedded polymorphic comment list + add comment form - example?

    - by odigity
    Hey, all. Working on my first Rails app. I've searched all around - read a bunch of tutorials, articles, and forum posts, watched some screencasts, and I've found a few examples that come close to what I'm trying to do (notably http://railscasts.com/episodes/154-polymorphic-association and ep 196 about nested model forms), but not exactly. I have two models (Podcast and BlogPost) that need to be commentable, and I have a Comment model that is polymorphically related to both. The railscasts above had a very similar example (ep 154), but Ryan used a full set of nested routes, so there were specific templates for adding and editing comments. What I want to do is show the list of comments right on the Podcast or BlogPost page, along with an Add Comment form at the bottom. I don't need a separate add template/route, and I don't need the ability to edit, only delete. This is a pretty common design on the web, but I can't find a Rails example specifically about this pattern. Here's my current understanding: I need routes for the create and delete actions, of course, but there are no templates associated with those. I'm also guessing that the right approach is to create a partial that can be included at the bottom of both the Podcast and BlogPost show template. The logical name for the partial seems to me to be something like _comments.html.haml. I know it's a common convention to have the object passed to the partial be named after the template, but calling the object 'comments' seems to not match my use case, since what I really need to pass is the commentable object (Podcast or BlogPost). So, I guess I'd use the locals option for the render partial call? (:commentable = @podcast). Inside the partial, I could call commentable.comments to get the comments collection, render that with a second partial (this time with the conventional use case, calling the partial _comment.html.haml), then create a form that submits to... what? REST-wise, it should be a POST to the collection, which would be /podcast|blogpost/:id/comments, and I think the helper for that is podcast_comments_path(podcast) if it were a podcast - not sure what to do though, since I'm using polymorphic comments. That would trigger the Comment.create action, which would then need to redirect back to the podcast|blogpost path /podcast|blogpost/:id. It's all a bit overwhelming, which is why I was really hoping to find a screencast or example that specifically implements this design.

  • client ip address in ASP.NET (.asmx) webservices

    - by Zain Shaikh
    I am using ASP.Net (.asmx) web services with Silverlight. since there is no way to find client ip address in Silverlight, therefore I had to log this on service end. these are some methods I have tried: Request.ServerVariables(”REMOTE_HOST”) HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"] HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; Request.UserHostAddress() Request.UserHostName() string strHostName = System.Net.Dns.GetHostName(); string clientIPAddress = System.Net.Dns.GetHostAddresses(strHostName).GetValue(0).ToString(); All the above methods work fine on my local system, but when I publish my service on production server. it starts giving errors. Error: Object reference not set to an instance of an object. StackTrace: at System.Web.Hosting.ISAPIWorkerRequestInProc.GetAdditionalServerVar(Int32 index) at System.Web.Hosting.ISAPIWorkerRequestInProc.GetServerVariable(String name) at System.Web.Hosting.ISAPIWorkerRequest.GetRemoteAddress() at System.Web.HttpRequest.get_UserHostAddress()

  • java.lang.NoSuchMethodError: main when starting HelloWorld with Eclipse Scala plugin

    - by Matt Sheppard
    I've just been playing with Scala, and installed the Eclipse plugin as described at http://www.scala-lang.org/node/94, but after entering the "Hello World" test example and setting up the run configuration as described, I get the following error Exception in thread "main" java.lang.NoSuchMethodError: main For reference the code is package hello object HelloWorld extends Application { println("Hello World!") } I've tinkered a bit with the obvious solutions (adding a main method, adding a singleton object with a main method) but I'm clearly doing something wrong. Can anyone get their test example to work, or point out what I am doing wrong?

  • Saving State Dynamic UserControls...Help!

    - by Cognitronic
    I have page with a LinkButton on it that when clicked, I'd like to add a Usercontrol to the page. I need to be able to add/remove as many controls as the user would like. The Usercontrol consists of three dropdownlists. The first dropdownlist has it's auotpostback property set to true and hooks up the OnSelectedIndexChanged event that when fired will load the remaining two dropdownlists with the appropriate values. My problem is that no matter where I put the code in the host page, the usercontrol is not being loaded properly. I know I have to recreate the usercontrols on every postback and I've created a method that is being executed in the hosting pages OnPreInit method. I'm still getting the following error: The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases. Here is my code: Thank you!!!! bool createAgain = false; IList<FilterOptionsCollectionView> OptionControls { get { if (SessionManager.Current["controls"] != null) return (IList<FilterOptionsCollectionView>)SessionManager.Current["controls"]; else SessionManager.Current["controls"] = new List<FilterOptionsCollectionView>(); return (IList<FilterOptionsCollectionView>)SessionManager.Current["controls"]; } set { SessionManager.Current["controls"] = value; } } protected void Page_Load(object sender, EventArgs e) { Master.Page.Title = Title; LoadViewControls(Master.MainContent, Master.SideBar, Master.ToolBarContainer); } protected override void OnPreInit(EventArgs e) { base.OnPreInit(e); System.Web.UI.MasterPage m = Master; Control control = GetPostBackControl(this); if ((control != null && control.ClientID == (lbAddAndCondtion.ClientID) || createAgain)) { createAgain = true; CreateUserControl(control.ID); } } protected void AddAndConditionClicked(object o, EventArgs e) { var control = LoadControl("~/Views/FilterOptionsCollectionView.ascx"); OptionControls.Add((FilterOptionsCollectionView)control); control.ID = "options" + OptionControls.Count.ToString(); phConditions.Controls.Add(control); } public event EventHandler<Insight.Presenters.PageViewArg> OnLoadData; private Control FindControlRecursive(Control root, string id) { if (root.ID == id) { return root; } foreach (Control c in root.Controls) { Control t = FindControlRecursive(c, id); if (t != null) { return t; } } return null; } protected Control GetPostBackControl(System.Web.UI.Page page) { Control control = null; string ctrlname = Page.Request.Params["__EVENTTARGET"]; if (ctrlname != null && ctrlname != String.Empty) { control = FindControlRecursive(page, ctrlname.Split('$')[2]); } else { string ctrlStr = String.Empty; Control c = null; foreach (string ctl in Page.Request.Form) { if (ctl.EndsWith(".x") || ctl.EndsWith(".y")) { ctrlStr = ctl.Substring(0, ctl.Length - 2); c = page.FindControl(ctrlStr); } else { c = page.FindControl(ctl); } if (c is System.Web.UI.WebControls.CheckBox || c is System.Web.UI.WebControls.CheckBoxList) { control = c; break; } } } return control; } protected void CreateUserControl(string controlID) { try { if (createAgain && phConditions != null) { if (OptionControls.Count > 0) { phConditions.Controls.Clear(); foreach (var c in OptionControls) { phConditions.Controls.Add(c); } } } } catch (Exception ex) { throw ex; } } Here is the usercontrol's code: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="FilterOptionsCollectionView.ascx.cs" Inherits="Insight.Website.Views.FilterOptionsCollectionView" %> namespace Insight.Website.Views { [ViewStateModeById] public partial class FilterOptionsCollectionView : System.Web.UI.UserControl { protected void Page_Load(object sender, EventArgs e) { } protected override void OnInit(EventArgs e) { LoadColumns(); ddlColumns.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(ColumnsSelectedIndexChanged); base.OnInit(e); } protected void ColumnsSelectedIndexChanged(object o, EventArgs e) { LoadCriteria(); } public void LoadColumns() { ddlColumns.DataSource = User.GetItemSearchProperties(); ddlColumns.DataTextField = "SearchColumn"; ddlColumns.DataValueField = "CriteriaSearchControlType"; ddlColumns.DataBind(); LoadCriteria(); } private void LoadCriteria() { var controlType = User.GetItemSearchProperties()[ddlColumns.SelectedIndex].CriteriaSearchControlType; var ops = User.GetItemSearchProperties()[ddlColumns.SelectedIndex].ValidOperators; ddlOperators.DataSource = ops; ddlOperators.DataTextField = "key"; ddlOperators.DataValueField = "value"; ddlOperators.DataBind(); switch (controlType) { case ResourceStrings.ViewFilter_ControlTypes_DDL: criteriaDDL.Visible = true; criteriaText.Visible = false; var crit = User.GetItemSearchProperties()[ddlColumns.SelectedIndex].SearchCriteria; ddlCriteria.DataSource = crit; ddlCriteria.DataBind(); break; case ResourceStrings.ViewFilter_ControlTypes_Text: criteriaDDL.Visible = false; criteriaText.Visible = true; break; } } public event EventHandler OnColumnChanged; public ISearchCriterion FilterOptionsValues { get; set; } } }

  • Building an XML editor in java and RichFaces

    - by Mark Lewis
    Hello I'm building an XML editor using the above technologies. In essence, I want to read in a whole XML file to a java object, and refer using this object to each element in the XML node tree (grouped into entries) to display the content locked, have separate padlocks for the user to click to 'unlock' an entry allow overwriting of the data, and to submit this entry. 'Add entry', 'Duplicate entry', 'Delete entry' are also functions I'd like to add. I already use dom4j and XPath to access areas of the XML file so some of the work in theory is already done. Given the above, I was going to use these two together with inplaceInputs to allow the user to edit the XML and JSF validators to check the data coming in. Is this the best way to approach this problem, or is there a more straightforward route than XPathing a whole record? I started looking at jaxb but I'm new at java and jsf but I've got the feeling I won't be by the end.. Thanks

  • Using JSON input in Ruby method on Rails

    - by Zachary
    I am using jQuery to make an AJAX call to a ruby method in my controller. The javascript looks something like this: var latLongJSON = { "address": [ {"lat" : 50, "long" : 50} ] }; var returnedAddresses; $.ajax({ type: "GET", data: latLongJSON, url: "map/getaddresses", success: function(data) { returnedAddresses = JSON.parse(data); } }); Then in my 'getaddresses' method, my parameter coming through looks like: Parameters: {"address"=>"[object Object]"} I'm not sure what to do with this. I'm fairly new to Ruby, and I'm not sure if I need to convert this to something else, or what. Ideally I want to be able to pass in multiple sets of lat/long in the 'address' array, then be able to iterate over those in my Ruby code.

  • How to make the subview in a UIScrollView to refresh when we zoom it?

    - by wolverine
    I have subclassed UIView object inside a uiscrollview which displays a pdf page. I can zoom that page. But when I do so, the inside view is zoomed and is getting blurred. I understood that the inner view shud be refreshed and i called setNeedsDisplay. But no change have happened and its the same even now. Below is the code for drawRect for the subclassed uiview. - (void)drawRect:(CGRect)rect { if(document)//the pdf document object { CGContextRef ctx = UIGraphicsGetCurrentContext(); CGContextSaveGState(ctx); CGContextTranslateCTM(ctx, 0.00, [self bounds].size.height); NSLog(@"%f",[self bounds].size.height); CGContextScaleCTM(ctx, 1.0, -1.0); CGContextConcatCTM(ctx, CGPDFPageGetDrawingTransform(page, kCGPDFCropBox, [self bounds], 0, true)); CGContextDrawPDFPage(ctx, page); CGContextRestoreGState(ctx); } }

  • Index was outside the bounds of the array. IndexOutOfRangeException in LINQ to SQL

    - by gtas
    Im getting this exception in the protected virtual void SendPropertyChanged(String propertyName) { if ((this.PropertyChanged != null)) { this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); <---- HERE !!! } } of one recently table association i created, there lots of same associations around the database, and this happened in the 4 specific tables i added. Its 1...* relationship and association is Primary Table - Id (identity auto generated) Foreign PId column int not null. I just dont get it....Im using SqlMetal for generation, i regenerated the schema, rebuild, same. This is causing while inserting row in DevExpress XtraGrid, but i dont think this should be issue, same control with same functionality but for different tables works ok. I use grid's event for append value in a property when the entity creating. I disabled this but same again. Recreated the association. No change, exception occurs. Any ideas?

  • Send parameters in order in HTTPService

    - by Suraj Chandran
    I am trying to work with a simple HTTPService. The problem is that my webservice is conscious of the order of arguments it gets. I will tell the problem with an example: var service:HTTPService = new HTTPService(); var params:Object = new Object(); params.rows = 0; params.facet = "true"; service.send(params); Note that in the above code I have mentioned the parameter rows before facet, but the url I recieve is facet=true&rows=0. So I recieve the argument rows before facet and hence my webservice does not work. I figured out that the contents of array is always sent in alphabetical order, which I dont want. Is there any way I can achieve explict ordering of parameters sent? Note that I am not in power of changing the logic of webservice(its basically a RPC service supporting both desktop and web client). Thanks.

  • WPF -- Event Threading, GUI updating question

    - by LSTayon
    I'm trying to send two events to the main window so that I can show some kind of animation that will let the user know that I'm updating the data. This is an ObservableCollection object so the OnPropertyChanged is immediately picked up by the bindings on the main window. The sleep is only in there so that the user can see the animation. However, the first OnPropetyChanged is never seen. I'm assuming this is because we're in a single thread here and the timer_Tick has to finish before the GUI updates. Any suggetions? In VB6 land we would use a DoEvents or a Form.Refresh. Thanks! private void timer_Tick(object sender, EventArgs e) { Loading = "Before: " + DateTime.Now.ToString(); OnPropertyChanged("Loading"); LoadData(); Thread.Sleep(1000); //Loading = Visibility.Hidden; Loading = "After: " + DateTime.Now.ToString(); OnPropertyChanged("Loading"); }

  • Does OpenRasta support Mono?

    - by Earlz
    Although Mono support is not a big deal for us, I figured OpenRasta supported it cause it has some commit messages about it.. Well, I tried to build it on Mono and got Ambiguous type references(after manually creating like 10 obj directories.) So I tried just using the prebuilt assemblies I had on hand and that gave me an Object Reference Not Set To Instance of an Object (the usual error I have with mono.. ) at OpenRasta.Diagnostics.DebuggerLoggingTraceListener.WriteAll (using xsp2) Is there official support for Mono or am I missing some sorta extra step for deployment?

  • Scheme Formatting Help

    - by Logan
    I've been working on a project for school that takes functions from a class file and turns them into object/classes. The assignment is all about object oriented programming in scheme. My problem however is that my code doesn't format right. The output it gives me whenever I give it a file to pass in wraps the methods of the class in a list, making it so that the class never really gets declared. I can't for the life of me figure out how to get the parenthesis wrapping the method list to remove. I would really appreciate any help.
