• Google Calendar like interface

  - by John Virgolino

  I need to write an application that essentially functions like a week-view of a calendar, columns for the days and then rows for appointments. Where the height of the appointment box visually represents time. In my case, I just don't want the time of day as the vertical axis, I just want hours or mins. The Google AJAX approach is very clean and easy to use and would be perfect, I think, but my major knowledge comes in ASP.Net and Windows Forms (.Net). I don't want to reinvent the wheel, but I find my mind is stuck on this problem and that I would have to create an interface from scratch for this. I have checked out the Infragistics product (used it for other projects) and read up a lot on the Google API's including their Ajax toolkit. I haven't done Java, however learning a language is not my issue, it's learning the particulars that will help me reach my goal that I feel will take most of the time. Am I making a mountain out of a mole hill? Is this really a lot easier than I think? This is starting to sound like a Dear Abby post - I'll stop now. Any advice or insight would be great! Thanks all!

• WPF: How can I KEEP the same ItemTemplate instance once its created ??

  - by Samir Sabri

  Hello, Here is a cinario: I have a ListView, with ItemsSource = ProjectModel.Instance.PagesModelsCollection; where PagesModelsCollection is an ObservableCollection In the ListView XAML part: <ListView.ItemTemplate> <DataTemplate x:Name="PagesViewDataTemplate"> <DataTemplate.Resources> <Style x:Key="PageHostStyle" TargetType="{x:Type p:KPage}"> </Style> </DataTemplate.Resources> <StackPanel x:Name="MarginStack" Margin="50,50,50,50" > <p:KPage x:Name="PageHost" > </p:KPage> </StackPanel> </DataTemplate> </ListView.ItemTemplate> The problem is the ITemTemplate is re-created each time we refresh the Items. So, if we have 100 Item in the list view, another 100 new ItemTemplate instance will be created if we refresh the items! As a result, if we add UIElements on one of the ItemTemplate intances, those added UIElements will be lost, because the old ITemTemplate is replaced with a new one! How can I KEEP the ItemTemplate instance once its created ??

• ruby on rails-Problem with the selection form helper

  - by winter sun

  Hello I have a form in witch users can add their working hours view them and edit them (All in one page). When adding working hours the user must select a project from a dropdown list. In case the action is adding a new hour record the dropdown field should remain empty (not selected) in case the action is edit the dropdown field should be selected with the appropriate value. In order to overcome this challenge I wrote the following code <% if params[:id].blank?%> <select name="hour[project_id]" id="hour_project_id"> <option value="nil">Select Project</option> <% @projects.each do|project|%> <option value="<%=project.id %>"><%=project.name%></option> <% end%> </select> <% else %> <%= select('hour','project_id', @projects.collect{|project|[project.name,project.id]},{:prompt => 'Select Project'})%> <% end %> So in case of save action I did the dropdown list only with html, and in case of edit action I did it with the collect method. It works fine until I tried to code the errors. The problem is that when I use the error method: validates_presence_of :project_id it didn't recognize it in the html form of the dropdown list and don’t display the error message (its working only for the dropdown with the collect method). I will deeply appreciate your instructions and help in this matter

• UITableView Inactive Until Scroll iPhone

  - by dubbeat

  HI, I'm trying to find the cause of some annoying behaviour with my UITableView. In each cell of my table (10 of them ) I asynchronously load an image. The problem is, is that if I don't touch the app at all the imageviews will permanently show a loading icon. However as soon as I scroll a cell off the screen and back on again the image shows straight away. What could be causing this "stuck in the mud" behaviour? Is there a way to force whatever gets called when the list is scrolled to make the needed update happen? #define ASYNC_IMAGE_TAG 9999 #define LABEL_TAG 8888 // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { PromoListItem *promo = [promoList objectAtIndex:indexPath.row]; static NSString *CellIdentifier = @"Cell"; AsyncImageView *asyncImageView = nil; UILabel *label = nil; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; CGRect frame; frame.origin.x = 0; frame.origin.y = 0; frame.size.width = 100; frame.size.height = 100; asyncImageView = [[[AsyncImageView alloc] initWithFrame:frame] autorelease]; asyncImageView.tag = ASYNC_IMAGE_TAG; [cell.contentView addSubview:asyncImageView]; frame.origin.x = 110; frame.size.width =100; label = [[[UILabel alloc] initWithFrame:frame] autorelease]; label.tag = LABEL_TAG; [cell.contentView addSubview:label]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } else { asyncImageView = (AsyncImageView *) [cell.contentView viewWithTag:ASYNC_IMAGE_TAG]; label = (UILabel *) [cell.contentView viewWithTag:LABEL_TAG]; } NSURL *url = [NSURL URLWithString:promo.imgurl]; [asyncImageView loadImageFromURL:url]; label.text = promo.artistname; return cell; }

• Webfaction apache + mod_wsgi + django configuration issue

  - by Dmitry Guyvoronsky

  A problem that I stumbled upon recently, and, even though I solved it, I would like to hear your opinion of what correct/simple/adopted solution would be. I'm developing website using Django + python. When I run it on local machine with "python manage.py runserver", local address is http://127.0.0.1:8000/ by default. However, on production server my app has other url, with path - like "http://server.name/myproj/" I need to generate and use permanent urls. If I'm using {% url view params %}, I'm getting paths that are relative to / , since my urls.py contains this urlpatterns = patterns('', (r'^(\d+)?$', 'myproj.myapp.views.index'), (r'^img/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/img' }), (r'^css/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/css' }), ) So far, I see 2 solutions: modify urls.py, include '/myproj/' in case of production run use request.build_absolute_uri() for creating link in views.py or pass some variable with 'hostname:port/path' in templates Are there prettier ways to deal with this problem? Thank you. Update: Well, the problem seems to be not in django, but in webfaction way to configure wsgi. Apache configuration for application with URL "hostname.com/myapp" contains the following line WSGIScriptAlias / /home/dreamiurg/webapps/pinfont/myproject.wsgi So, SCRIPT_NAME is empty, and the only solution I see is to get to mod_python or serve my application from root. Any ideas?

• CATransaction: Layer Changes But Does Not Animate

  - by macinjosh

  I'm trying to animate part of UI in an iPad app when the user taps a button. I have this code in my action method. It works in the sense that the UI changes how I expect but it does not animate the changes. It simply immediately changes. I must be missing something: - (IBAction)someAction:(id)sender { UIViewController *aViewController = <# Get an existing UIViewController #>; UIView *viewToAnimate = aViewController.view; CALayer *layerToAnimate = viewToAnimate.layer; [CATransaction begin]; [CATransaction setAnimationDuration:1.0f]; CATransform3D rotateTransform = CATransform3DMakeRotation(0.3, 0, 0, 1); CATransform3D scaleTransform = CATransform3DMakeScale(0.10, 0.10, 0.10); CATransform3D positionTransform = CATransform3DMakeTranslation(24, 423, 0); CATransform3D combinedTransform = CATransform3DConcat(rotateTransform, scaleTransform); combinedTransform = CATransform3DConcat(combinedTransform, positionTransform); layerToAnimate.transform = combinedTransform; [CATransaction commit]; // rest of method... } I've tried simplifying the animation to just change the opacity (for example) and it still will not animate. The opacity just changes instantly. That leads me to believe something is not setup properly. Any clues would be helpful!

• Question about passing data using intents

  - by Joe K 1973

  Hi everyone, I'm trying to modify the Notepad tutorial (the Notepadv3 solution) to take in a value into the NoteEdit class, given to by the Notepadv3 class. I've successfully used .putExtra in the OnListItemClick method to place the value into the NoteEdit class, but I'm struggling to do this for the createNote method; I'm getting a force close when I try to create a new note. I bet there's a simple solution, but I'm pretty new to Java & Android and would very much appreciate your help. Here's the code in question in the Notepadv3 class: private void createNote() { Intent i = new Intent(this, NoteEdit.class); i.putExtra("key", 1); startActivityForResult(i, ACTIVITY_CREATE); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); Intent i = new Intent(this, NoteEdit.class); i.putExtra(NotesDbAdapter.KEY_ROWID, id); i.putExtra("key", 1); startActivityForResult(i, ACTIVITY_EDIT); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent intent) { super.onActivityResult(requestCode, resultCode, intent); fillData(); } And here's the receiving code in the NoteEdit class: mRowId = savedInstanceState != null ? savedInstanceState.getLong(NotesDbAdapter.KEY_ROWID) : null; if (mRowId == null) { Bundle extras = getIntent().getExtras(); mRowId = extras != null ? extras.getLong(NotesDbAdapter.KEY_ROWID) : null; value = extras.getInt("key"); } I'm fairly sure that (mRowId == null) is not true when I'm using the createNote method so therefore getExtras won't be called. One of my questions would be how can I make my NoteEdit class get this value when I use the createNote method? I'm new to this so sorry if this is a simple question for you all. Thanks, Joe

  right basically what ive got is an app which is a ball and bat and its how many bounces you can achieve, it works alright but there is one problem, when the ball hits the side of the bat it throws it off course and its like the frame of the ball is bouncing in the frame of the bat, Here is my code in my mainview.m #import "MainView.h" #define kGameStateRunning 1 @implementation MainView @synthesize paddle, ball; - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:touch.view]; CGPoint xLocation = CGPointMake(location.x,paddle.center.y); paddle.center = xLocation; } -(IBAction) play { pos = CGPointMake(14.0,7.0); [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(onTimer) userInfo:nil repeats:YES]; } -(void) onTimer { ball.center = CGPointMake(ball.center.x+pos.x,ball.center.y+pos.y); if(ball.center.x > 320 || ball.center.x < 0) pos.x = -pos.x; if(ball.center.y > 460 || ball.center.y < 0) pos.y = -pos.y; [self checkCollision]; } -(void) checkCollision { if(CGRectIntersectsRect(ball.frame,paddle.frame)) { pos.y = -pos.y; } } @end can anyone work out the problem here?

• MVC: Submit one form from a page with multiple forms

  - by Rob

  I'm working in an ASP.NET 3.5 MVC application where i've got a view with multiple forms in it. Form 1 contains information about products and will form a shoppingcart with a remove button. Form 2 is as below and is to be used to get the information from the shoppingcart and create an order of it. <% using (Html.BeginForm()) { %> <%=Html.Hidden(Order.ProductId", "E63EF586-F625-4C8D-B82E-E63A6FA4A63C")%> <%=Html.Hidden(Order.Amount", 1)%> <input type="submit" value="Pay" /> <%} % The first form contains a similar beginform with a foreach loop to get the information about the products from the model. When i use the submit button on the second form everything seems to be submitted and the action in the controller for the first form is trying to handle the request. That is where the error occurce because the information in the viewmodel isn't corresponding to what is being expected. The controller which is trying to handle the request: [AcceptVerbs(HttpVerbs.Post)] public ActionResult ShowShoppingcartForm([Bind(Prefix = "Order")] MyViewmodel viewModel) { //.. } The controller which is expected to handle the request: [AcceptVerbs(HttpVerbs.Post)] public ActionResult SaveOrder([Bind(Prefix = "Order")] MyViewmodel viewModel) { throw new NotImplementedException(); }

• Problem accessing variable in a nested form partial

  - by brad

  I have a nested form in a rails view that is called like this <% f.fields_for :invoice_item_numbers do |item_no_form| %> <%= render 'invoice_item_number', :f => item_no_form %> <% end %> and the partial (_invoice_item_number.html.erb) looks like this <div class='invoice_item_numbers'> <% if f.object.new_record? %> <li><%= f.label :item_number %><%= f.text_field :item_number %> <%= link_to_function "remove", "$(this).parent().remove()", :class => 'remove_link' %></li> <% else %> <li class="inline"><%= f.label :item_number %><%= f.text_field :item_number %> </li><li class="inline"><%= f.label :description %><%= invoice_item_number.description %></li><li><%= f.label :amount %><%= f.text_field :amount %> <%= f.check_box '_destroy', :class => 'remove_checkbox' %> <%= f.label '_destroy', 'remove', :class => 'remove_label' %></li> <% end %> </div> This fails with the error message undefined method `description' for nil:NilClass Why does invoice_item_number return a nil object in this partial? It is obviously being defined somehow because if I change it to something else (e.g. item_number.description then the error message becomes undefined local variable or methoditem_number' for #instead. The invoice_item_number object that is being displayed by this partial is being used perfectly well by the form helpers as<%= f.text_field :item_number %and<% f.text_field :amount %both work perfectly well. I have tried a number of solutions such as using@invoice_item_number` and explicitly defining an object in the render method but these have not worked. Presumably there is a very simple answer to this.

• How to get resultset with stored procedure calls over two linked servers?

  - by räph

  I have problems filling a temporary table with the resultset from a procedure call on a linked server, in which again a procedure on another server is called. I have a Stored Procedure sproc1 with the following code, which calls another procedure sproc2 on a linked server. SET @sqlCommand = 'INSERT INTO #tblTemp ( ModuleID, ParamID) ' + '( SELECT * FROM OPENQUERY(' + @targetServer + ', ' + '''SET FMTONLY OFF; EXEC ' + @targetDB + '.usr.sproc2 ' + @param + ''' ) )' exec ( @sqlCommand ) Now in the called sproc2 I again call a third procedure sproc3 on another linked server, which returns my resultset. SET @sqlCommand = 'EXEC ' + @targetServer +'.database.usr.sproc3 ' + @param exec ( @sqlCommand ) The whole thing doen't work, as I get an SQL error 7391 The operation could not be performed because OLE DB provider "%ls" for linked server "%ls" was unable to begin a distributed transaction. I already checked the hints at this microsoft article, but without success. But maybe, I can change the code in sproc1. Would there be some alternative to the temp table and the open query? Just calling stored procedures from server A to B to C and returning the resultset is working (I do this often in the application). But this special case with the temp table and openquery doesn't work! Or is it just not possible what I am trying to do? The microsft article states: Check the object you refer on the destination server. If it is a view or a stored procedure, or causes an execution of a trigger, check whether it implicitly references another server. If so, the third server is the source of the problem. Run the query directly on the third server. If you cannot run the query directly on the third server, the problem is not actually with the linked server query. Resolve the underlying problem first. Is this my case? PS: I can't avoid the architecture with the three servers.

• PendingIntents in Notifications

  - by Mariano Kamp

  I would like to show a notification that displays the progress of an ongoing operation. That works well for me. But at the same time the remote view should contain cancel button to stop the ongoing operation. The usual content intent should still do something else, i.e. not cancel the ongoing operation. It seems though that I can only have one intent. I have to specify a contentIntent that is launched when clicking on the notification: If I don't specify that I get something along those lines: E/ActivityManager( 62): Activity Manager Crash E/ActivityManager( 62): java.lang.IllegalArgumentException: contentIntent required ... For the "cancel" button I set another intent: Intent cancelSyncIntent = new Intent("com.xyz.CANCEL_SYNC"); contentView.setOnClickPendingIntent(R.id.cancel_sync, PendingIntent.getBroadcast(context, 0, cancelSyncIntent, 0)); But this never works. I always get the content intent when the button is clicked. It looks like I cannot use buttons in remote views of notifications?! I could probably display a text: "<< Press to cancel operation ", but that seems rather heavy handed.

• How can I map stored procedure result into a custom class with linq-to-sql?

  - by Remnant

  I have a stored procedure that returns a result set (4 columns x n Rows). The data is based on multiple tables within my database and provides a summary for each department within a corporate. Here is sample: usp_GetDepartmentSummary DeptName EmployeeCount Male Female HR 12 5 7 etc... I am using linq-to-sql to retrieve data from my database (nb - have to use sproc as it is something I have inherited). I would like to call the above sproc and map into a department class: public class Department { public string DeptName {get; set;} public int EmployeeCount {get; set;} public int MaleCount {get; set;} public int FemaleCount {get; set;} } In VS2008, I can drag and drop my sproc onto the methods pane of the linq-to-sql designer. When I examine the designer.cs the return type for this sproc is defined as: ISingleResult<usp_GetDepartmentSummaryResult> What I would like to do is amend this somehow so that it returns a Department type so that I can pass the results of the sproc as a strongly typed view: <% foreach (var dept in Model) { %> <ul> <li class="deptname"><%= dept.DeptName %></li> <li class="deptname"><%= dept.EmployeeCount %></li> etc... Any ideas how to achieve this? NB - I have tried amending the designer.cs and dbml xml file directly but with limited success. I admit to being a little out of my depth when it comes to updating those files directly and I am not sure it is best practice? Would be good to get some diretion. Thanks much

• Django caching seems to be causing problems

  Hey guys, i have just implemented the Django Cache Local Memory back end in some my code, however it seems to be causing a problem.

• Debugging Actionmailer

  - by Trip

  I have actionmailer set up. Emails are not being sent, and no errors. Where can I start my search to debug this? class Notifier < ActionMailer::Base default_url_options[:host] = APP_DOMAIN def email_blast(user, subject, message) subject subject from NOTIFIER_EMAIL recipients user.email sent_on Time.zone.now body :user => user.first_name + ' ' + user.last_name, :message => message end I do get a return in my log that the email was sent, just no actual email goes through. Also the reason, that this is not working is because I switched form a cluster to a solo box and some server settings were overwritten. I suspect that is probably the reason why this is not working. Anyone know what specific server settings I would have to look at ? UPDATE: ActionMailer::Base.delivery_method = :sendmail config.action_mailer.default_url_options = { :host => "75.101.153.93" } I found this in my production.rb . This code was originally here when it worked. Again, I believe that there must be something missing on my server..I did a 'which sendmail' and it returned /usr/bin/sendmail , so I added this : config.action_mailer.raise_delivery_errors = false config.action_mailer.perform_deliveries = true config.action_mailer.sendmail_settings = { :location => '/usr/bin/sendmail', :arguments => '-i -t' } Redeployed, restarted the server, and tested it. No emails were sent. The production.log said something was sent : Processing MediaController#create_a_video (for 173.161.167.41 at 2010-06-03 11:58:13) [GET] Parameters: {"action"=>"create_a_video", "controller"=>"media", "organization_id"=>"470", "_"=>"1275591493194"} Sent mail to [email protected] Rendering media/create_a_video Completed in 128ms (View: 51, DB: 1) | 200 OK [http://invent.hqchannel.com/organizations/470/media/create_a_video?_=1275591493194]

• I need some pointers on how to implement inertia

  - by gargantaun

  Ok, so I've created a little plugin that takes a bunch of elements and creates a sort of never ending list. I'll try to explain... I have a div, and it's got about 20 elements tags in it. When the user scrolls up, the top element moves out of view and is moved to the bottom of the list. And vice-versa so that when the user scrolls down, the bottom element is moved to the top of the list. This is specifically for Mobile Safari (iPad, iPhone) web content and you can see the work in progress here... http://appliedworks.co.uk/files/times/SVGTests/drumView/drum.html You'll need an iPad or iPhone top see the scrolling in action. You can see the plugin code here... http://appliedworks.co.uk/files/times/SVGTests/drumView/drumView-0.1b.js What I would like to do is implement inertia so the scrolling slows to a halt in response to how fast or slow the user is scrolling when their finger leaves the screen. Just like the inertia commonly found in the iPhone / iPad UI. The problem is, every time an element moves to the top or the bottom of the list, the scollTop value for the parent div is adjusted to make it look like all the elements are staying in the same place. Which means the scrollTop value is never more than the top elements total height. So there's no value I can think of that I can keep on manipulating to give the illusion of inertia. I'm stumped. Does anyone have any suggestions?

• BeginInvoke on ObservableCollection not immediate.

  - by Padu Merloti

  In my code I subscribe to an event that happens on a different thread. Every time this event happens, I receive an string that is posted to the observable collection: Dispatcher currentDispatcher = Dispatcher.CurrentDispatcher; var SerialLog = new ObservableCollection<string>(); private void hitStation_RawCommandSent(object sender, StringEventArgs e) { string command = e.Value.Replace("\r\n", ""); Action dispatchAction = () => SerialLog.Add(command); currentDispatcher.BeginInvoke(dispatchAction, DispatcherPriority.Render); } The code below is in my view model (could be in the code behind, it doesn't matter in this case). When I call "hitstation.PrepareHit", the event above gets called a couple times, then I wait and call "hitStation.HitBall", and the event above gets called a couple more times. private void HitBall() { try { try { Mouse.OverrideCursor = Cursors.Wait; //prepare hit hitStation.PrepareHit(hitSpeed); Thread.Wait(1000); PlayWarning(); //hit hitStation.HitBall(hitSpeed); } catch (TimeoutException ex) { MessageBox.Show("Timeout hitting ball: " + ex.Message); } } finally { Mouse.OverrideCursor = null; } } The problem I'm having is that the ListBox that is bound to my SerialLog gets updated only when the HitBall method finishes. I was expecting seeing a bunch of updates from the PrepareHit, a pause and then a bunch more updates from the HitBall. I've tried a couple of DispatcherPriority arguments, but they don't seem to have any effect.

• IIS7 integrated mode MVC deploy 404 not found on some actions

  - by majkinetor

  Hello. Once deployed parts of my web-application stop working. Index-es on each controller do work, and one form posting via Ajax, other then that yields 404. I understand that nothing particular should be done in integrated mode. One interesting thing is that 1 AJAX action is working. I don't know how to proceed with troubleshooting. Some info: App is using default app pool set to integrated mode. WebApp is done in net framework 3.5. I use default routing model. Along web.config in root there is web.config in /View folder referencing HttpNotFoundHandler. OS is Windows Server 2008. Admins issued aspnet_regiis.exe -i IIS 7 Any help is appreciated. Thx. EDIT: Noticed one very strange thing. One ajax call works, other ajax call doesn't works as I login, but when I move to ther page and return to that one it starts working ?!

• Ajax UpdatePanels SetFocus issue

  - by George

  I set the AutoPostback property of a textbox to True so I can process the TextChanged event on the server and, based on what they typed in the textbox, appropriately display a message in an update panel. The problem is, when the partial screen refresh is performed, no control on the screen has focus. 99% of the time, when the text in the textbox is changed, it is because the user has tabbed forward, and so, to limit the disruption in the lost of focus, I perform a "Focus" call on teh next control in the tab sequence. For the most part, this works OK, but of course, is disputive if the user is tabbing in the reverse order or has used the mouse to set the focus to another control. In these situations, the focus would be set to the next control even though the user was trying to set focus elsewhere. OK, that sucks. Now what I consider the bigger problem with calling the focus method on the server: In IE, it works OK, but in Mozilla Firefox and Chrome, setting the focus causes a repositioning of the scroll bar, even though none is necessary because the control is already in view. I realize that I could switch to doing AJAX web service calls, but these darn Updae Panels are so convenient if used in moderation. is there anyway to use updatepanels and not have these focus/scroll issues?

  I'm not a web admin, and I'm new to IIS. So, I'm looking for advice. My MVC application (e.g. fooapp) is the default application for my site (e.g. foo.bar). I used IIS Manager to add the site to IIS7. When I import the application, IIS Manager wants to put it in it's own directory (/foo), and tells me I shouldn't put it in the base (site) directory. This means that to get to my default MVC view, I have to enter the URL http://foo.bar/fooapp/. Needless to say, I want to get there via http://foo.bar/ I see 2 possible solutions: Add a default page to the site directory that redirects to the MVC app. Ignore the IIS admonition and load the app into the site directory. My IIS7 knowledge is limited. I have played around with some options (such as HTTP Redirect). Since nothing changed, I obviously don't understand what I'm doing. Anyway, if there are some considered "best practices" and/or other suggestions, please let me know.

• SL3 Nav framework + MVVM ligh

  - by Murari

  Hi All, Thanks for taking time to read through my question. Any guidance is really appreciated. I am using SL3 Navigation framework in my LOB application. I m currently using MVVM Light as the framework guidance. I have a datagrid consisting of employees and when the "user" clicks on "employee id link" in the datagrid, i am transferring the user to "Edit Page". I would like to transfer the "employee id" as query parameter to "edit page". The issue here is: I can access the query parameter in the EditStaffView.xaml.cs - which i don't want to do. protected override void OnNavigatedTo(NavigationEventArgs e) { if (this.NavigationContext.QueryString.ContainsKey("staffcode")) { string title = this.NavigationContext.QueryString["staffcode"]; } } I would like to retrieve the query parameter in my viewmodel and based on the query parameter, i will perform certain operations. When the constructor is called I would like the "view" to pass the staffid as shown below public EditStaffViewModel(int staffId) { LoadData(staffId); } I am constructing my hyperlink buttons in the datagrid dyanmically as shown below: staffListingModel.HyperlinkNavigationUri = string.Format("{0}{1}", NavigationUri.DataEntryEditStaff,"?staffcode={" + staffListingModel.StaffCode + "}"); and XAML looks HyperlinkButton Content="{Binding StaffCode,Mode=TwoWay}" NavigateUri="{Binding HyperlinkNavigationUri}" HyperlinkButton Any idea how to do this ?? Thanks for the help. Murari

• hint and textview with right gravity and a singleline

  - by codeScriber

  I've opened a bug but i was wondering if anyone encountered this issue and knows a workaround. If you define a text view with a hint inside it, give it right gravity (android:gravity="right") then if you define android:singleLine=true or android:maxLines="1" or android:scrollHorizonatally="true" you don't see the hint. removing the right gravity returns the hint to the left side, removing all the tree params i mentioned above puts the hint on the right side. i want my hint on the right, but i need a single horizontal line... here's the sample layout that doesn't show the hint: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="5dp"> <EditText android:layout_width="fill_parent" android:layout_gravity="center_vertical|right" android:layout_height="wrap_content" android:layout_margin="6dp" android:textSize="16sp" android:paddingRight="5dp" android:id="@+id/c" android:gravity="right" android:hint="hello!!!" android:scrollHorizontally="true" android:maxLines="1" android:singleLine="true"/> </LinearLayout> i checked on 1.6 and 2.1 emulators and it reproduces 100%, i'm prettysure it's a bug, i don't see the connection between single line and the hint.... what's more the hint got it's own layout in the TextView (mLayout and mHintLayout both exists, in onDraw if the text length is 0 mHintLayout if mHint is not null is used).

• Help with Struts Action mapping

  - by nicotine

  I am having a problem with my struts application it is a class enrollment app and when the user clicks on a "show enrolled courses" button it is supposed to show the courses they are enrolled in but it shows nothing at the moment. Struts/Apache does not return any errors, it Just shows a blank page and I cannot figure out why. My action mapping in my struts-config: <action path="/showEnrolled" type="actions.ShowEnrolledAction" name="UserFormEnrolled" scope="request" validate="true" input="/students/StudentMenu.jsp"> <forward name="success" path="/students/enrolled.jsp"/> </action> My link to the jsp enrolled.jsp page: <li><html:form action="/showEnrolled"> <html:hidden property="id" value= "<%=request.getRemoteUser()%>"/> <html:submit value = "View Enrolled Classes"/> </html:form> </li> When I click the link I get nothing but my menu on the page. The text headings for the page are not even displayed.
