  • ASP.NET TextBox TextChanged event not firing in custom EditorPart

    - by Ben Collins
    This is a classic sort of question, I suppose, but it seems that most people are interested in having the textbox cause a postback. I'm not. I just want the event to fire when a postback occurs. I have created a webpart with a custom editorpart. The editorpart renders with a textbox and a button. Clicking the button causes a dialog to open. When the dialog is closed, it sets the value of the textbox via javascript and then does __doPostBack using the ClientID of the editorpart. The postback happens, but the TextChanged event never fires, and I'm not sure if it's a problem with the way __doPostBack is invoked, or if it's because of the way I'm setting up the event handler, or something else. Here's what I think is the relevant portion of the code from the editorpart: protected override void CreateChildControls() { _txtListUrl = new TextBox(); _txtListUrl.ID = "targetSPList"; _txtListUrl.Style.Add(HtmlTextWriterStyle.Width, "60%"); _txtListUrl.ToolTip = "Select List"; _txtListUrl.CssClass = "ms-input"; _txtListUrl.Attributes.Add("readOnly", "true"); _txtListUrl.Attributes.Add("onChange", "__doPostBack('" + this.ClientID + "', '');"); _txtListUrl.Text = this.ListString; _btnListPicker = new HtmlInputButton(); _btnListPicker.Style.Add(HtmlTextWriterStyle.Width, "60%"); _btnListPicker.Attributes.Add("Title", "Select List"); _btnListPicker.ID = "browseListsSmtButton"; _btnListPicker.Attributes.Add("onClick", "mso_launchListSmtPicker()"); _btnListPicker.Value = "Select List"; this.AddConfigurationOption("News List", "Choose the list that serves as the data source.", new Control[] { _txtListUrl, _btnListPicker }); if (this.ShowViewSelection) { _txtListUrl.TextChanged += new EventHandler(_txtListUrl_TextChanged); _ddlViews = new DropDownList(); _ddlViews.ID = "_ddlViews"; this.AddConfigurationOption("View", _ddlViews); } } protected override void OnPreRender(EventArgs e) { ScriptLink.Register(this.Page, "PickerTreeDialog.js", true); string lastSelectedListId = string.Empty; if (!this.WebId.Equals(Guid.Empty) && !this.ListId.Equals(Guid.Empty)) { lastSelectedListId = SPHttpUtility.EcmaScriptStringLiteralEncode( string.Format("SPList:{0}?SPWeb:{1}:", this.ListId.ToString(), this.WebId.ToString())); } string script = "\r\n var lastSelectedListSmtPickerId = '" + lastSelectedListId + "';" + "\r\n function mso_launchListSmtPicker(){" + "\r\n if (!document.getElementById) return;" + "\r\n" + "\r\n var listTextBox = document.getElementById('" + SPHttpUtility.EcmaScriptStringLiteralEncode(_txtListUrl.ClientID) + "');" + "\r\n if (listTextBox == null) return;" + "\r\n" + "\r\n var serverUrl = '" + SPHttpUtility.EcmaScriptStringLiteralEncode(SPContext.Current.Web.ServerRelativeUrl) + "';" + "\r\n" + "\r\n var callback = function(results) {" + "\r\n if (results == null || results[1] == null || results[2] == null) return;" + "\r\n" + "\r\n lastSelectedListSmtPickerId = results[0];" + "\r\n var listUrl = '';" + "\r\n if (listUrl.substring(listUrl.length-1) != '/') listUrl = listUrl + '/';" + "\r\n if (results[1].charAt(0) == '/') results[1] = results[1].substring(1);" + "\r\n listUrl = listUrl + results[1];" + "\r\n if (listUrl.substring(listUrl.length-1) != '/') listUrl = listUrl + '/';" + "\r\n if (results[2].charAt(0) == '/') results[2] = results[2].substring(1);" + "\r\n listUrl = listUrl + results[2];" + "\r\n listTextBox.value = listUrl;" + "\r\n __doPostBack('" + this.ClientID + "','');" + "\r\n }" + "\r\n LaunchPickerTreeDialog('CbqPickerSelectListTitle','CbqPickerSelectListText','websLists','', serverUrl, lastSelectedListSmtPickerId,'','','/_layouts/images/smt_icon.gif','', callback);" + "\r\n }"; this.Page.ClientScript.RegisterClientScriptBlock(typeof(ListPickerEditorPart), "mso_launchListSmtPicker", script, true); if ((!string.IsNullOrEmpty(_txtListUrl.Text) && _ddlViews.Items.Count == 0) || _listSelectionChanged) { _ddlViews.Items.Clear(); if (!string.IsNullOrEmpty(_txtListUrl.Text)) { using (SPWeb web = SPContext.Current.Site.OpenWeb(this.WebId)) { foreach (SPView view in web.Lists[this.ListId].Views) { _ddlViews.Items.Add(new ListItem(view.Title, view.ID.ToString())); } } _ddlViews.Enabled = _ddlViews.Items.Count > 0; } else { _ddlViews.Enabled = false; } } base.OnPreRender(e); } void _txtListUrl_TextChanged(object sender, EventArgs e) { this.SetPropertiesFromChosenListString(_txtListUrl.Text); _listSelectionChanged = true; } Any ideas? Update: I forgot to mention these methods, which are called above: protected virtual void AddConfigurationOption(string title, Control inputControl) { this.AddConfigurationOption(title, null, inputControl); } protected virtual void AddConfigurationOption(string title, string description, Control inputControl) { this.AddConfigurationOption(title, description, new List<Control>(new Control[] { inputControl })); } protected virtual void AddConfigurationOption(string title, string description, IEnumerable<Control> inputControls) { HtmlGenericControl divSectionHead = new HtmlGenericControl("div"); divSectionHead.Attributes.Add("class", "UserSectionHead"); this.Controls.Add(divSectionHead); HtmlGenericControl labTitle = new HtmlGenericControl("label"); labTitle.InnerHtml = HttpUtility.HtmlEncode(title); divSectionHead.Controls.Add(labTitle); HtmlGenericControl divUserSectionBody = new HtmlGenericControl("div"); divUserSectionBody.Attributes.Add("class", "UserSectionBody"); this.Controls.Add(divUserSectionBody); HtmlGenericControl divUserControlGroup = new HtmlGenericControl("div"); divUserControlGroup.Attributes.Add("class", "UserControlGroup"); divUserSectionBody.Controls.Add(divUserControlGroup); if (!string.IsNullOrEmpty(description)) { HtmlGenericControl spnDescription = new HtmlGenericControl("div"); spnDescription.InnerHtml = HttpUtility.HtmlEncode(description); divUserControlGroup.Controls.Add(spnDescription); } foreach (Control inputControl in inputControls) { divUserControlGroup.Controls.Add(inputControl); } this.Controls.Add(divUserControlGroup); HtmlGenericControl divUserDottedLine = new HtmlGenericControl("div"); divUserDottedLine.Attributes.Add("class", "UserDottedLine"); divUserDottedLine.Style.Add(HtmlTextWriterStyle.Width, "100%"); this.Controls.Add(divUserDottedLine); }

  • WPF Custom Buttons below ListBox Items

    - by Ryan
    WPF Experts - I am trying to add buttons below my custom listbox and also have the scroll bar go to the bottom of the control. Only the items should move and not the buttons. I was hoping for some guidance on the best way to achieve this. I was thinking the ItemsPanelTemplate needed to be modified but was not certain.

  • Custom GTK widget to bypass GTK layout engine?

    - by fret
    I have an application layer that I'd like to port to Gtk that has all it's own layout code and I don't really want to spend 'n' months re-writting it to work with the Gtk layout system, but rather just using the existing internal layout code and have Gtk render the resulting widgets. I've started by writting my own widget after trying several of the built in containers. Basically I'm looking for something like the GtkFixed container that doesn't have a minimum size, i.e. Gtk will fit the first widget to the entire window, and all the child widgets will lay themselves out so that they fill the area. If I use GtkFixed for that, the window is always limited to the size of the initial layout, as thats the "requested" space. I can't resize it smaller than that using the edges of the window decor. Maybe I need schooling in allocation vs requesting. My googling so far hasn't found the information I need to make this work. I did try. I'm using the C api at the moment, and I'm targetting Win32 and Linux. So far I have a shell app working in Win32 that puts up an empty window. But the first child widget is limiting the resizing to it's initial size.

  • Access custom error messages for InArray validator when using Zend_Form_Element_Select

    - by Ben Waine
    Hello, I'm using Zend Framework 1.62 (becuase we are deploying the finished product to a Red Hat instance, which doesn't have a hgih enough PHP version to support ZF1.62). When creating a Form using Zend Form, I add a select element, add some multi options. I use the Zend Form as an in-object validation layer, passing an objects values through it and using the isValid method to determine if all the values fall within normal parameters. Zend_Form_Element_Select works exactly as expected, showing invalid if any other value is input other than one of the multi select options I added. The problem comes when I want to display the form at some point, I cant edit the error message created by the pre registered 'InArray' validator added automatically by ZF. I know I can disable this behaviour, but it works great apart from the error messages. I've tryed the following: $this->getElement('country')->getValidator('InArray')->setMessage('The country is not in the approved lists of countries'); // Doesn't work at all. $this->getElement('country')->setErrorMessage('The country is not in the approved lists of countries'); // Causes a conflict elswhere in the application and doesnt allow granular control of error messages. Anyone have any ideas? Ben

  • Help with Custom Workflow that monitors an objects state

    - by zSysop
    I need to write a workflow that monitors the status of an object. (It could wait for days or hours for a state to change) I have the following states for the object (lets call it an Issue object): 1) Created 2) Unowned 3) Owned 4) UnAssigned 4) Assigned 6) In Progress 7) Signed Off 8) Closed I would also need to take some action on an object if the object was within a certain state for a defined period (not really sure on how this can be accomplished either). The object's owner/assignee can change at any point (i.e. Go from In Progress to UnOwned) so i am guessing that a state machine diagram is what i would need to use. If my thinking is incorrect then please let me know. My application is written in c# .net 3.5. I was thinking about having a service method called CreateIssue that would insert the ticket into the db and then begin an instance of a workflow (with the object or an id of the object as parameters). I wasn't sure of how the workflow would then know when a particular object has been updated, or if the object's state has changed. I've done some really simple "hello world" type of apps with windows workflow foundation 3.5 but have not yet grasped how to do go about implementing something like this. Any direction on this will be extremely helpful. Thanks in advance.

  • Custom template for Django's comments application does not display fields

    - by Jannis
    Hi, I want to use django.contrib.comments in a blogging application and customize the way the form is displayed. My problem is that I can't get the fields to display although displaying the hidden fields works just fine. I had a look at the docs and compared it with the regular way of displaying forms but honestly I don't know why the following doesn't work out: {% get_comment_form for comments_object as form %} <form action="{% comment_form_target %}" method="POST"> […] {% for hidden in form.hidden_fields %} {{ hidden }} {% endfor %} {% for field in form.fields %} {{field}} {% endfor %} […] </form> The output looks like this: <form action="/comments/post/" method="POST"> <input type="hidden" name="content_type" value="flatpages.flatpage" id="id_content_type" /> <input type="hidden" name="object_pk" value="1" id="id_object_pk" /> <input type="hidden" name="timestamp" value="1269522506" id="id_timestamp" /> <input type="hidden" name="security_hash" value="ec4…0fd" id="id_security_hash" /> content_type object_pk timestamp security_hash name email url comment honeypot […] </form> </div> Can you tell me what I'm doing wrong? Thanks in advance

  • Custom View embed in Gallery crashes while key press

    Hi there, I'd like to find some stuff to replace the Tab component, so I'd make a custom View named StringView, which has the ability to display text, and to embed it into a Gallery. But it always crashes with error "NullPointerException at InputMethodManager". I have no idea about this, any help&tip&suggest are appreciate. Detail of my issue: First I'd created a class StringView extends View: public class StringView extends View { protected final Paint mPaint = new Paint(Paint.ANTI_ALIAS_FLAG); protected String mString; protected int mAscent; // Constructor public StringView(Context context, String string) { super(context); mPaint.setARGB(255, 255, 60, 10); mPaint.setTextSize(30); //mPaint.setFakeBoldText(true); mString = string; setPadding(20,15,20,15); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); int w = this.getPaddingLeft(); int h = this.getPaddingTop() - mAscent; canvas.drawText(mString, w, h, mPaint); } public void setString(String str) { mString = str; this.requestLayout(); this.invalidate(); } public String getString() { return mString; } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { setMeasuredDimension(measureWidth(widthMeasureSpec), measureHeight(heightMeasureSpec)); } /** * Determines the width of this view * @param measureSpec A measureSpec packed into an int * @return The width of the view, honoring constraints from measureSpec */ private int measureWidth(int measureSpec) { int result = 0; int specMode = MeasureSpec.getMode(measureSpec); int specSize = MeasureSpec.getSize(measureSpec); if (specMode == MeasureSpec.EXACTLY) { // We were told how big to be result = specSize; } else { // Measure the text result = (int) mPaint.measureText(mString) + getPaddingLeft() + getPaddingRight(); if (specMode == MeasureSpec.AT_MOST) { // Respect AT_MOST value if that was what is called for by measureSpec result = Math.min(result, specSize); } } return result; } /** * Determines the height of this view * @param measureSpec A measureSpec packed into an int * @return The height of the view, honoring constraints from measureSpec */ private int measureHeight(int measureSpec) { int result = 0; int specMode = MeasureSpec.getMode(measureSpec); int specSize = MeasureSpec.getSize(measureSpec); mAscent = (int) mPaint.ascent(); if (specMode == MeasureSpec.EXACTLY) { // We were told how big to be result = specSize; } else { // Measure the text (beware: ascent is a negative number) result = (int) (-mAscent + mPaint.descent()) + getPaddingTop() + getPaddingBottom(); if (specMode == MeasureSpec.AT_MOST) { // Respect AT_MOST value if that was what is called for by measureSpec result = Math.min(result, specSize); } } return result; } } Second I put it in to Gallery through Adapter Gallery gallery = (Gallery) findViewById(R.id.gallery); gallery.setAdapter(new ImageAdapter(this)); ImageAdapter: public class ImageAdapter extends BaseAdapter { int mGalleryItemBackground; private Context mContext; private View[] mImages = genSerielImageViews(); public ImageAdapter(Context c) { mContext = c; TypedArray a = obtainStyledAttributes(R.styleable.Gallery); mGalleryItemBackground = a.getResourceId( R.styleable.Gallery_android_galleryItemBackground, 0); a.recycle(); } private View[] genSerielImageViews() { if (true) { int N = 6; StringView[] views = new StringView[N]; for (int i=0; i<N; i++) { views[i] = new StringView(mContext, "ITEM #" + Integer.toString(i) ); } return views; } else { int N = 6; TextView[] views = new TextView[N]; for (int i=0; i<N; i++) { views[i] = new TextView( mContext ); views[i].setText("CCTV #" + Integer.toString(i) ); } return views; } } public int getCount() { return mImages.length; } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { return mImages[position]; } } Then Compile&Run, press keypad RIGHT and I got a crash, It's turns out a weird InputMethodManager error: 03-18 07:22:33.568: ERROR/AndroidRuntime(958): Uncaught handler: thread main exiting due to uncaught exception 03-18 07:22:33.648: ERROR/AndroidRuntime(958): java.lang.NullPointerException 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at android.view.inputmethod.InputMethodManager.startInputInner(InputMethodManager.java:940) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at android.view.inputmethod.InputMethodManager.checkFocus(InputMethodManager.java:1114) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at android.view.ViewRoot.handleMessage(ViewRoot.java:1869) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at android.os.Handler.dispatchMessage(Handler.java:99) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at android.os.Looper.loop(Looper.java:123) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at android.app.ActivityThread.main(ActivityThread.java:4310) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at java.lang.reflect.Method.invokeNative(Native Method) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at java.lang.reflect.Method.invoke(Method.java:521) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 03-18 07:22:33.648: ERROR/AndroidRuntime(958): at dalvik.system.NativeStart.main(Native Method) Thanks.

  • Why can't I Bind a viewmodel property to a dependency property of a custom control

    - by Robert
    I want to use a color picker in my wpf application and I saw a nice looking one on this codeproject page. The control works fine until I want to connect the control to a viewmodel. I created a small test program with this viewmodel: public class ColorViewModel : ViewModelBase { public ColorViewModel() { LineColor = Brushes.Yellow; } SolidColorBrush _brushColor; public SolidColorBrush LineColor { get { return _brushColor; } set { _brushColor = value; RaisePropertyChanged(() => LineColor); } } } The test program has a textbox and the colorpicker controls: <StackPanel Orientation="Horizontal"> <TextBlock Text="Please Select a Color" FontWeight="Bold" Margin="10" Foreground="{Binding Path=LineColor, UpdateSourceTrigger=PropertyChanged}"/> <vw:ColorPickerControlView x:Name="ForeColorPicker" Margin="10" CurrentColor="{Binding Path=LineColor, UpdateSourceTrigger=PropertyChanged }"/> </StackPanel> In the loaded event of the window I set the viewmodel to the datacontext like this: DataContext = new ColorViewModel(); The problem is that I can't seem to bind the LineColor property of the viewmodel to the CurrentColor property of the ColorPickerControlView. The CurrentControl property of the ColorPickerControlView seems to be fine. The constructor looks like this: public ColorPickerControlView() { this.DataContext = this; InitializeComponent(); CommandBindings.Add(new CommandBinding(SelectColorCommand, SelectColorCommandExecute)); } In the constructor of the UserControl there is the line this.DataContext = this; I read that is is necessary to bind the dependency properties. Do I override this line when I set my viewmodel to the datacontext and is that why I can't bind to the CurrentColor property? Is there any workaround? Or did I make another mistake?

  • silverlight security with WCF service, Forms Authentication and Custom Form Ticket

    - by user74825
    I have a silverlight application with login on the silverlight page. It uses Forms Authentication with WCF authentication service and customer Membership Provider. Something like : http://blogs.msdn.com/phaniraj/archive/2009/09/10/using-the-ado-net-data-services-silverlight-client-library-in-x-domain-and-out-of-browser-scenarios-ii-forms-authentication.aspx So, SL page login page calls the WCF service authentication service, it validates using DB - brings back username and password. Now, in each subsequent calls (in Global.asax in Authenticate_Request, I get HttpContext.User.IsAuthenticated and HttpContext.User.UserName). I have all this working properly. But, I just don't want the username, but more information surrounding the user, like UserId, UserAddress, UserAssociateCustomer etc. I tried couple of different approaches. 1) Use HttpContext.Cache as a dictionary to save the item and get it off based on httpcontext.user.name, problem is cache can be erased if there memory is being used heavily. 2) Tried CustomFormsAuth Ticket, when forms authentication writes a ticket, I intercept CreatingCookie method and write additional info in formauthentication ticket, so that I can read it in subsequent requests, I am having problems with this approach, I don't find the ticket in subsequent requests. I read about how we should use REsponse.Redirect, but where do I redirect user from WCF call. How do you guys implement the above scenario? Any best practices.? Any issues you see with going on HTTPS? All examples (or most of them) just explains simple forms authentication with "I am logged in message".. Any suggestions ?

  • Embedding/deploying custom font in .NET app

    - by Swingline Rage
    Is there an official way to distribute (deploy) a specific font with a .NET application? We have a (public domain) "LED font" that prints numbers with the retro LED instrumentface look. This is a standard True Type or Open Type font like any other except it looks funky. Obviously for that to work, this font needs to be on the user's machine. But we'd prefer to not force the user to "install our special font into your font folder". We'd prefer to either load a Font object directly from the TTF, or programatically install the font so it's available. How do applications handle this sort of things? Eg, I notice Adobe XYZ installs various fonts on the system without user intervention. That's what we'd like to do. EDIT: okay, ideally, we'd prefer not to install the font directly. We don't want our nifty themed LED font showing up in the user's font dropdown in MS Word. We'd prefer to use this font, but restrict its use or appearance to our app. Any way to do this? Thanks!

  • How to display custom processing message in JQuery datatables

    - by Sukhi
    i am using datatables api to display data in my asp.net4.0 application; datatables I have one column [ Delete ] to delete the row data.when i click on this link i send a jquery ajax request to delete the row from database. I want to display a message such as [ Deleting record... ] to the end user until data deleted by server side processing. I put a div on my page and write a message [ Deleting record... ] in a div when i click on delete link i display that message but when delete operation complete it also display a message [ Processing... ](which is inbuilt message of datatables) which looks like odd as two message are displaying. What can i do better to display message to the end user. JSCode $('#tblVideoList .delete').live('click', function (e) { e.preventDefault(); var oTable = $('#tblVideoList').dataTable(); var aPos = oTable.fnGetPosition(this.parentNode); var aData = oTable.fnGetData(aPos[0]); if (confirm('Are you sure want to delete the record.')) { $("#divDelete").show(); var today = new Date(); $.ajax({ type: "GET", cache: false, url: "samplepage.aspx", success: function (msg) { $("#divDelete").hide(); oTable.fnDraw(); } }); } return false; }); Thanks

  • How to do logout functionality in C# smart device application?

    - by Shailesh Jaiswal
    I am developng Smart device application in C#. It is a window application. In this application I am using Login form to authenticate the users. Only authenticated users can login into the system. In this application I am calling java web services which resides on another machine. I am passing mobile number & password from mu application's login form to the java web services. The java web services returns the userid after successful authentication. I made this userid static so that it can be used frequently with other web services. I using statc variables in this application so that they can be used at application level. After deploying the application I can see that emulator provides the close button with multiplicaton symbol. In this way I can close my form as well as application. But I want to provde one logout link in my application. Can I provide logout functionality in C# window application ? If yes, how to do that ? Please make sure that all the functions of .net framework does not work with .net compact framwork? Can you provide me the code or link through which can resolve the above issue ?

  • Application crashing on getting updated information from database using timer and storing it on loca

    - by Amit Battan
    In our multi - user application we are continuously interacting with database. We have a common class through which we are sending POST queries to database and obtaining xml files in return. We are using delegates of NSXMLParser to parse the obtained file. The problem with us is we are facing many crashes in it generally when application is idle and changed data in database is being fetched in background through timer which is invoked after every few seconds. We have also dealt with error handling through try and catch but it proves to be of no use in this case and mostly application crashes with following error : Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000020 Strange thing is that many times the fetching of updated data at background works very fine, same methods being successfully executed under similar conditions but suddenly it crashes on one of them. The codes we are using is as follows: // we are using timer in this way: chkOnlineUser=[NSTimer scheduledTimerWithTimeInterval:15 target:mmObject selector:@selector(threadOnlineUser) userInfo:NULL repeats:YES];

  • Replace low level web-service reference call transport with custom one

    - by hoodoos
    I'm not sure if title sounds right actually, so I will give more explanation here. I will begin from very beginning :) I'm using c# and .net for my development. I have an application that makes requests to some soap web-service and for each user request it produces 3 to 10 requests for web-service, they should all run async to finish in one time, so I use Async method of the web-service generated reference and then wait for result on callback. But it seems like it starts a thread (or takes it from pool) for every async call I make, so if I have 10 clients I got to spawn 30 to 100 threads and it sounds terrible even for my 16 cores server :) So i wanted to replace low level transport implementation with my own which uses non-blocking sockets and can handle at least 50 sockets run parallel in one thread with not much overhead. But I actually dunno where to put my override best. I analyzed System.Web.Services.Protocols.SoapHttpClientProtocol class and see that it has some GetWebRequest method which I actually could use. If only I could somehow interupt the object it creates and get a http request with all headers and body from there and then send it with my own sockets.. Any ideas what approach to use? Or maybe there's something built in the framework I can use?

  • Devise routes to only use custom sign in page

    - by eblume
    I am trying to learn Devise and seem to have hit a problem that is nearly the same as many, many questions here on SO but just slightly different enough that I am not getting much traction following those questions' threads. I have a very simple application. Users can sign in and sign out (and also the devise 'forgot password' stuff is enabled - I am not concerned about it at this time) and that is it. They can't register, they can't edit their profile other than to change their password, they can't do anything except sign in and sign out. (Account creation will, for now, be handled manually at the command line.) I would vastly prefer that the only page that users can log in from was "/" (root_path). I already have it working where you can log in from "/", and that is great. The problem I am having is that if you type in your user/password combination incorrectly from the root_path login page, it automatically sends you to the Devise sign-in page to continue trying to sign in. How can I make Devise redirect to root_path on sign-in failure? Here are my routes - they are probably not optimal or correctly configured and I would appreciate pointers on fixing them: root to: "core_pages#splash" devise_for :users, skip: [:sessions] as :user do # get 'signin' => 'devise/sessions#new', as: :new_user_session post 'signin' => 'devise/sessions#create', as: :user_session delete 'signout' => 'devise/sessions#destroy', as: :destroy_user_session, via: Devise.mappings[:user].sign_out_via end match '/home' => 'core_pages#home' Note the commented-out 'get signin' line. The system works without this line but, surprisingly (to me), "GET /signin" results in a HTTP 400 (OK) response and renders the Devise login template. I would prefer it return some sort of 'invalid request' or just silently redirect the user to root_path. Running rake routes on these routes gives: root / core_pages#splash user_password POST /users/password(.:format) devise/passwords#create new_user_password GET /users/password/new(.:format) devise/passwords#new edit_user_password GET /users/password/edit(.:format) devise/passwords#edit PUT /users/password(.:format) devise/passwords#update user_session POST /signin(.:format) devise/sessions#create destroy_user_session DELETE /signout(.:format) devise/sessions#destroy home /home(.:format) core_pages#home Thanks!

  • Avoid duplicate custom post type posts in multiple loops in Wordpress

    - by christinaaa
    I am running two loops with a custom post type of Portfolio (ID of 3). The first loop is for Featured and the second is for the rest. I plan on having more than 3 Featured posts in random order. I would like to have the Featured ones that aren't displaying in the first loop to show up in my second loop. How can I set this up so there are no duplicate posts? <?php /* Template Name: Portfolio */ get_header(); ?> <div class="section-bg"> <div class="portfolio"> <div class="featured-title"> <h1>featured</h1> </div> <!-- end #featured-title --> <div class="featured-gallery"> <?php $args = array( 'post_type' => 'portfolio', 'posts_per_page' => 3, 'cat' => 3, 'orderby' => 'rand' ); $loop = new WP_Query( $args ); while ( $loop->have_posts() ) : $loop->the_post(); ?> <div class="featured peek"> <a href="<?php the_permalink(); ?>"> <h1> <?php $thetitle = $post->post_title; $getlength = strlen($thetitle); $thelength = 40; echo substr($thetitle, 0, $thelength); if ($getlength > $thelength) echo '...'; ?> </h1> <div class="contact-divider"></div> <p><?php the_tags('',' / '); ?></p> <?php the_post_thumbnail('thumbnail', array('class' => 'cover')); ?> </a> </div> <!-- end .featured --> <?php endwhile; ?> </div> <!-- end .featured-gallery --> <div class="clearfix"></div> </div> <!-- end .portfolio --> </div> <!-- end #section-bg --> <div class="clearfix"></div> <div class="section-bg"> <div class="portfolio-gallery"> <?php $args = array( 'post_type' => 'portfolio', 'orderby' => 'rand'); $loop = new WP_Query( $args ); while ( $loop->have_posts() ) : $loop->the_post(); ?> <div class="featured peek"> <a href="<?php the_permalink(); ?>"> <h1> <?php $thetitle = $post->post_title; $getlength = strlen($thetitle); $thelength = 40; echo substr($thetitle, 0, $thelength); if ($getlength > $thelength) echo '...'; ?> </h1> <div class="contact-divider"></div> <p><?php the_tags('',' / '); ?></p> <a href="<?php the_permalink(); ?>"><?php the_post_thumbnail('thumbnail', array('class' => 'cover')); ?></a> </a> </div> <!-- end .featured --> <?php endwhile; ?> <div class="clearfix"></div> </div> <!-- end .portfolio-gallery --> <div class="clearfix"></div> </div> <!-- end #section-bg --> <?php get_footer(); ?> If possible, could the answer outline how to implement it into my existing code? Thank you. :)

  • Custom Solr sorting

    - by Tom
    Hello everyone, I've been asked to do an evaluation of Solr as an alternative for a commercial search engine. The application now has a very particular way of sorting results using something called "buckets". I'll try to explain with a bit of details: In the interface they have 2 fields: "what" and "where". Both fields are actually sets of fields (what = category, name, contact info... and where= country, state, region, city...) so the copyfield feature of Solr immediately comes to mind. Now based on the field generated the actual match the result should end up in a specific bucket. In particular the first bucket contains all the result documents that have an exact match on the category field, in the second bucket all exact matches on name, the third partial matches on category, the fourth partial matches on name, the fifth matches on contact info etc... Then within each of those first tier buckets all results are placed in second tier buckets depending on what location was matched: city, then region, then province and so on. To even complicate things more there is also a third tier bucket where results are placed according to the value of a ranking field: all documents with the value 1 in the ranking field go in bucket 1 and so on. And finally results should be randomized in the third tier bucket... On top of this they obviously want support for facets and paging. My apologies for the long mail but I would greatly appreciate feedback and/or suggestions. I'm aware that this that this is a very particular problem but everything that points me in the right direction is helpful. Cheers, Tom

  • In Visual Studio (2008) is there a way to have a custom dependent file on another custom file?

    - by rball
    Instead of a *.cs code behind or beside I'd like to have a *.js file. I'm developing a MVC application an have no need for a code beside because I have controllers, but in certain cases it'd be nice to have a JavaScript code beside or some way to associate the file to the page it's being used on. I suppose I could just name them similarly, but I'm wanting to show the association if possible so there's no question about what the file is for. Typically what I'm talking about is within Visual Studio now under your Global.asax file you will have a plus sign to the left: + Global.asax Once you expand it you'll get - Global.asax Global.asax.cs I'd like the same thing to happen: + Home.spark - Home.spark Home.spark.js Updated: My existing csproj file has a path to the actual file, not sure if that's screwing it up. I've currently got: <ItemGroup> <Content Include="Views\User\Profile.spark.js"> <DependentUpon>Views\User\Profile.spark</DependentUpon> </Content> </ItemGroup> <ItemGroup> <Content Include="Views\User\Profile.spark" /> </ItemGroup> and it's simply just showing the files besides each other.

  • Hundreds of custom UserControls create thousands of USER Objects

    - by Andy Blackman
    I'm creating a dashboard application that shows hundreds of "items" on a FlowLayoutPanel. Each "item" is a UserControl that is made up of 12 or labels. My app queries a database and then creates an "item" instance for each record, populating ethe labels and textboxes with data before adding it to the FlowLayoutPanel. After adding about 560 items to the panel, I noticed that the USER Objects count in my Task Manager had gone up to about 7300, which was much much larger than any other app on my machine. I did a quick spot of mental arithmetic (OK, I might have used calc.exe) and figured that 560 * 13 (12 labels plus the UserControl itself) is 7280. So that suddenly gave away where all the objects were coming from... Knowing that there is a 10,000 USER object limit before windows throws in the towel, I'm trying to figure better ways of drawing these items onto the FlowLayoutPanel. My ideas so far are as follows: 1) User-draw the "item", using graphics.DrawText and DrawImage in place of many of the labels. I'm hoping that this will mean 1 item = 1 USER Object, not 13. 2) Have 1 instance of the "item", then for each record, populate the instance and use the Control.DrawToBitmap() method to grab an image and then use that in the FlowLayoutPanel (or similar) So... Does anyone have any other suggestions ??? P.S. It's a zoomable interface, so I have already ruled out "Paging" as there is a requirement to see all items at once :( Thanks everyone.
