  • How do I make the 'Shut Down the Computer' window be monochrome ?

    - by Agmenor
    When I hit the power button of my computer, a window titled 'Shut Down the Computer' appears. It gives a few options, including shutting down or restarting. This window is different following the context I hit the power button : when logged in and seeing my desktop, it includes colourful icons (red for shutting down, for example). when I am not logged in yet, the icons are monochrome and a little bit more stylized. I clearly prefer the last type of icons : how do I set them as default whatever the context of use of the 'Shut Down the Computer' window ?

  • How do I get the name of a package, modify and install it?

    - by Ken
    I'm not very familiar with Ubuntu or Linux, but I'm a programmer, and some people told me that you can just go ahead and modify your system. So my question is, how do you go on about that? For instance, If I'm interested in modifying the behavior of the button or the desktop icons, or whatever it is: How do I get the source code? I guess I need the package name and download it. But how can I get the package name? Let's say I want the button package, where do I look to get the package name? is there a list on a website or a help file? Once I modify it, how can I replace the original with the new one? P.S. I had some troubles finding the right tags, feel free to edit them

  • Facebook likes reset after moving to HTTPS

    - by aarondicks
    I've got a question regarding the Facebook like button. We worked on a piece recently that embeds a number of social share buttons (please see the source code below). When the piece was released, it was on HTTP, and received over 2k likes (the URL 'slug' hasn't changed at all). The site was recently migrated to permanent-on HTTPS, and the like data has been reset, and we've been left with 50 new, recent likes. If you see in the source code, the URL is set explicitly to like the HTTP version, which I believe to be correct. Can anyone help me work out what's happened here? Here's the HTML bit of the like button: <div class="fb-like" data-href="http://www.harveywatersofteners.co.uk/history-interior-design" data-layout="box_count" data-action="like" data-show-faces="false" data-share="false"></div>

  • How do I remove Skype 4.3 from Ubuntu 14.04 LTS (32-bit)

    - by Lucas W
    I installed Skype on my nephew's new Ubuntu 14.04 LTS machine, and now we've decided to remove it. But I'm not able to locate it in my Installed programs section of Ubuntu Software Center. I'm able to call it up by opening the debian package, Software Center opens it up, but where I would normally see the "Remove" button, I have a "Reinstall" button. For the life of me, I can't figure out how to uninstall Skype. Any suggestions? In case you're wondering I used the version of Skype designed for 12.xx, as there was no option available for Ubuntu 14.xx.

Scenario I have a travel website puneritraveller.com, and for each destination featured in the website i have listed hotels, with a direct link to the website of the hotel. for example i have featured a destination 'Alibaug' with a hotels page - puneritraveller.com/alibaug-hotels.html , in this page i have given banner ads for a few hotels for example Yellow house which on clicking redirects to www.yellowhousealibag.com What i want to achieve is, when someone clicks on the banner ad for Yellow house they should be redirected to a page with a like button to facebook.com/puneritraveller and once he/she clicks on the like button should be redirected to www.yellowhousealibag.com Is this possible?

  • Force Gnome 3 to work

    - by nkg5
    I have Ubuntu 12.10 on dual-boot with windows XP. My PC specifications are AMD Sempron 2800+ 1,6GHz with 512 MB ram and ATI Radeon 9250 graphic card with 128 MB memory. As Unity works slow and I don't like it's look, I installed gnome-shell. But as you know, Gnome 3 won't work on it. But gnome classic without effects works great. Thing is, when I turn off windows (by holding the power button or pressing restart button) my resolution on Linux is changed to 1024x768, and I can only change it by turning off the PC and turning off it's power source. But it is not the problem. The problem is that it runs Gnome 3 after one restart, it also runs better than Unity. My question is: Can I somehow force gnome 3 to work always and disable some of it's effects so it can run better?

  • Laptop Hibernates after adapter is unplugged

    - by SpyrosR
    Hello i am experiencing a strange problem under Ubuntu 12.04. If I unplug the charger while my laptop is on,i don't see any messages but my laptop goes straight into a suspend or hibernate mode and it's a real pain to get it stable again afterwards. It always suspends (or hibernates) It always takes 2 attempts to restart it (press power button, it starts and it hibernates again, press power button and it starts and stays on) It sometimes has an effect on the wireless which doesn't come back clean and i either have to switch the wireless on and off a couple of times. I sometimes have to restart the laptop totally Is anyone else experiencing the same issues and if yes,is there any solution? Thank you in advance.

  • log in to web-app through less secure website [on hold]

    - by martijnve
    We are worried about the security of our website containing the login-button to our saas-application. Security measures put in place for our application won't do us much good if the website is hacked. The login button could be redirected to some malicious copy of our app. The product website is maintained by people outside the dev team. Those people are not too knowledgable concerning security. We (dev-team) could mantain the website ourselves but that would be a large burden on our small team. How is this usually handled?

  • Reporting services 2008: ReportExecution2005.asmx does not exist

    - by Shimrod
    Hi everyone, I'm trying to generate a report directly from the code (to send it by mail after). I make this in a windows service. So here is what I'm doing: Dim rview As New ReportViewer() Dim reportServerAddress As String = "http://server/Reports_client" rview.ServerReport.ReportServerUrl = New Uri(reportServerAddress) Dim paramList As New List(Of Microsoft.Reporting.WinForms.ReportParameter) paramList.Add(New Microsoft.Reporting.WinForms.ReportParameter("param1", t.Value)) paramList.Add(New Microsoft.Reporting.WinForms.ReportParameter("CurrentDate", Date.Now)) Dim reportsDirectory As String = "AppName.Reports" Dim reportPath As String = String.Format("/{0}/{1}", reportsDirectory, reportName) rview.ServerReport.ReportPath = reportPath rview.ServerReport.SetParameters(paramList) 'This is where I get the exception Dim mimeType, encoding, extension, deviceInfo As String Dim streamids As String() Dim warnings As Microsoft.Reporting.WinForms.Warning() deviceInfo = "<DeviceInfo><SimplePageHeaders>True</SimplePageHeaders></DeviceInfo>" Dim format As String = "PDF" Dim bytes As Byte() = rview.ServerReport.Render(format, deviceInfo, mimeType, encoding, extension, streamids, warnings) When debugging this code, I can see it throws a MissingEndpointException where I make the SetParameters(paramList) with this message: The attempt to connect to the report server failed. Check your connection information and that the report server is a compatible version. Looking in the server's log file, I can see this: ui!ReportManager_0-8!878!06/02/2010-11:34:36:: Unhandled exception: System.Web.HttpException: The file '/Reports_client/ReportExecution2005.asmx' does not exist. at System.Web.UI.Util.CheckVirtualFileExists(VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.Compilation.BuildManager.GetVPathBuildResult(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.Compilation.BuildManager.GetVPathBuildResult(HttpContext context, VirtualPath virtualPath) at System.Web.UI.WebServiceParser.GetCompiledType(String inputFile, HttpContext context) at System.Web.Services.Protocols.WebServiceHandlerFactory.GetHandler(HttpContext context, String verb, String url, String filePath) at System.Web.HttpApplication.MapHttpHandler(HttpContext context, String requestType, VirtualPath path, String pathTranslated, Boolean useAppConfig) at System.Web.HttpApplication.MapHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) I didn't find any resource on the web that fits my problem.

  • data validation on wpf passwordbox:type password, re-type password

    - by black sensei
    Hello Experts !! I've built a wpf windows application in with there is a registration form. Using IDataErrorInfo i could successfully bind the field to a class property and with the help of styles display meaningful information about the error to users.About the submit button i use the MultiDataTrigger with conditions (Based on a post here on stackoverflow).All went well. Now i need to do the same for the passwordbox and apparently it's not as straight forward.I found on wpftutorial an article and gave it a try but for some reason it wasn't working. i've tried another one from functionalfun. And in this Functionalfun case the properties(databind,databound) are not recognized as dependencyproperty even after i've changed their name as suggested somewhere in the comments plus i don't have an idea whether it will work for a windows application, since it's designed for web. to give you an idea here is some code on textboxes <Window.Resources> <data:General x:Key="recharge" /> <Style x:Key="validButton" TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}" > <Setter Property="IsEnabled" Value="False"/> <Style.Triggers> <MultiDataTrigger> <MultiDataTrigger.Conditions> <Condition Binding="{Binding ElementName=txtRecharge, Path=(Validation.HasError)}" Value="false" /> </MultiDataTrigger.Conditions> <Setter Property="IsEnabled" Value="True" /> </MultiDataTrigger> </Style.Triggers> </Style> <Style x:Key="txtboxerrors" TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> <Setter Property="Validation.ErrorTemplate"> <Setter.Value> <ControlTemplate> <DockPanel LastChildFill="True"> <TextBlock DockPanel.Dock="Bottom" FontSize="8" FontWeight="ExtraBold" Foreground="red" Padding="5 0 0 0" Text="{Binding ElementName=showerror, Path=AdornedElement.(Validation.Errors)[0].ErrorContent}"></TextBlock> <Border BorderBrush="Red" BorderThickness="2"> <AdornedElementPlaceholder Name="showerror" /> </Border> </DockPanel> </ControlTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> </Window.Resources> <TextBox Margin="12,69,12,70" Name="txtRecharge" Style="{StaticResource txtboxerrors}"> <TextBox.Text> <Binding Path="Field" Source="{StaticResource recharge}" ValidatesOnDataErrors="True" UpdateSourceTrigger="PropertyChanged"> <Binding.ValidationRules> <ExceptionValidationRule /> </Binding.ValidationRules> </Binding> </TextBox.Text> </TextBox> <Button Height="23" Margin="98,0,0,12" Name="btnRecharge" VerticalAlignment="Bottom" Click="btnRecharge_Click" HorizontalAlignment="Left" Width="75" Style="{StaticResource validButton}">Recharge</Button> some C# : class General : IDataErrorInfo { private string _field; public string this[string columnName] { get { string result = null; if(columnName == "Field") { if(Util.NullOrEmtpyCheck(this._field)) { result = "Field cannot be Empty"; } } return result; } } public string Error { get { return null; } } public string Field { get { return _field; } set { _field = value; } } } So what are suggestion you guys have for me? I mean how would you go about this? how do you do this since the databinding first purpose here is not to load data onto the fields they are just (for now) for data validation. thanks for reading this.

  • No OpenID endpoint found

    - by azamsharp
    I am trying to use the DotNetOpenId library to add OpenID support on a test website. For some reason it keeps giving me the following error when running on FireFix. Keep in mind that I am using localhost as I am testing it on my local machine. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using DotNetOpenAuth.OpenId.Extensions.ProviderAuthenticationPolicy; using DotNetOpenAuth.OpenId.Extensions.SimpleRegistration; using DotNetOpenAuth.OpenId.RelyingParty; namespace TableSorterDemo { public partial class Login : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { var openid = new OpenIdRelyingParty(); if (openid.GetResponse() != null) { switch (openid.GetResponse().Status) { case AuthenticationStatus.Authenticated: var fetch = openid.GetResponse().GetExtension(typeof(ClaimsResponse)) as ClaimsResponse; var nick = fetch.Nickname; var email = fetch.Email; break; } } } protected void OpenIdLogin1_LoggedIn(object sender, OpenIdEventArgs e) { var openid = new OpenIdRelyingParty(); if(openid.GetResponse() != null) { switch(openid.GetResponse().Status) { case AuthenticationStatus.Authenticated: var fetch = openid.GetResponse().GetExtension(typeof (ClaimsResponse)) as ClaimsResponse; var nick = fetch.Nickname; var email = fetch.Email; break; } } } protected void OpenIdLogin1_LoggingIn(object sender, OpenIdEventArgs e) { var openid = new OpenIdRelyingParty(); var req = openid.CreateRequest(OpenIdLogin1.Text); var fetch = new ClaimsRequest(); fetch.Email = DemandLevel.Require; fetch.Nickname = DemandLevel.Require; req.AddExtension(fetch); req.RedirectToProvider(); return; } } } Also, if I run the same page in Chrome then I get the following: Login failed: This message has already been processed.

  • Writing a Javascript library that is code-completion and code-inspection friendly

    - by Vivin Paliath
    I recently made my own Javascript library and I initially used the following pattern: var myLibrary = (function () { var someProp = "..."; function someFunc() { ... } function someFunc2() { ... } return { func: someFunc, fun2: someFunc2, prop: someProp; } }()); The problem with this is that I can't really use code completion because the IDE doesn't know about the properties that the function literal is returning (I'm using IntelliJ IDEA 9 by the way). I've looked at jQuery code and tried to do this: (function(window, undefined) { var myLibrary = (function () { var someProp = "..."; function someFunc() { ... } function someFunc2() { ... } return { func: someFunc, fun2: someFunc2, prop: someProp; } }()); window.myLibrary = myLibrary; }(window)); I tried this, but now I have a different problem. The IDE doesn't really pick up on myLibrary either. The way I'm solving the problem now is this way: var myLibrary = { func: function() { }, func2: function() { }, prop: "" }; myLibrary = (function () { var someProp = "..."; function someFunc() { ... } function someFunc2() { ... } return { func: someFunc, fun2: someFunc2, prop: someProp; } }()); But that seems kinda clunky, and I can't exactly figure out how jQuery is doing it. Another question I have is how to handle functions with arbitrary numbers of parameters. For example, jQuery.bind can take 2 or 3 parameters, and the IDE doesn't seem to complain. I tried to do the same thing with my library, where a function could take 0 arguments or 1 argument. However, the IDE complains and warns that the correct number of parameters aren't being sent in. How do I handle this?

  • Weird - "The EntityReference object could not be serialized" when serializing from an ASP.NET Web Si

    - by Mikey Cee
    I have an Entity Framework data model. Part of the model is a Customer entity. The web service provides a method to get a customer, and to receive an updated version of this customer to be persisted. To test this, I created a new ASP.NET web Application, (Solution Add New Project ASP.NET Web Application), then added a reference to my service reference using the standard Add Service Reference dialog. I then call the service using the following code: var client = new CustomerServiceClient(); var customer = client.GetCustomerByID(18); // get it customer.LimitDown = 100; // change it client.SaveCustomer(customer); // persist it Everything works as expected. Now, I do exactly the same thing, but this time with as ASP.NET Web Site (Solution Add New Web Site ASP.NET Web Site). I add the reference in a similar fashion and copy and paste the code above into the new site. But now I get the following exception thrown on the 4th line: System.InvalidOperationException The EntityReference object could not be serialized. This type of object cannot be serialized when the RelationshipManager belongs to an entity object that does not implement IEntityWithRelationships. Source Error: Line 2474: Line 2475: public SkyWalkerCustomerService.OperationResult SaveCustomer(SkyWalkerCustomerService.Customer customer) { Line 2476: return base.Channel.SaveCustomer(customer); Line 2477: } Line 2478: } Stack Trace: System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) +9475203 System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) +345 SkyWalkerCustomerService.ICustomerService.SaveCustomer(Customer customer) +0 SkyWalkerCustomerService.CustomerServiceClient.SaveCustomer(Customer customer) in c:\Windows\Microsoft.NET\Framework\v4.0.30128\Temporary ASP.NET Files\testsite2\dd2bcf8d\f95604ff\App_WebReferences.fz4h7x7l.0.cs:2476 _Default.Page_Load(Object sender, EventArgs e) in c:\Users\Mike\Documents\Repositories\UWC\SkyWalker\TestSite2\Default.aspx.cs:17 System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) +14 System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +35 System.Web.UI.Control.OnLoad(EventArgs e) +91 System.Web.UI.Control.LoadRecursive() +61 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1966 Googling for this error returns very little.

  • ASP.net MVC HttpException strange file not found

    - by Paddy
    I'm running asp.net MVC site on IIS6 - I've edited my routing to look like the following: routes.MapRoute( "Default", "{controller}.aspx/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); routes.MapRoute( "Root", "", new { controller = "Home", action = "Index", id = "" } ); So all my urls now contain .aspx (as per one of the solutions from Phil Haack). Now, I catch all unhandled exceptions using Elmah, and for almost every page request, I get the following error caught by Elmah, that I never see on the front end (everything works perfectly): System.Web.HttpException: The file '/VirtualDirectoryName/Home.aspx' does not exist.

  • Overwrite clean method in Django Custom Forms

    - by John
    Hi I have wrote a custom widget class AutoCompleteWidget(widgets.TextInput): """ widget to show an autocomplete box which returns a list on nodes available to be tagged """ def render(self, name, value, attrs=None): final_attrs = self.build_attrs(attrs, name=name) if not self.attrs.has_key('id'): final_attrs['id'] = 'id_%s' % name if not value: value = '[]' jquery = u""" <script type="text/javascript"> $("#%s").tokenInput('%s', { hintText: "Enter the word", noResultsText: "No results", prePopulate: %s, searchingText: "Searching..." }); $("body").focus(); </script> """ % (final_attrs['id'], reverse('ajax_autocomplete'), value) output = super(AutoTagWidget, self).render(name, "", attrs) return output + mark_safe(jquery) class MyForm(forms.Form): AutoComplete = forms.CharField(widget=AutoCompleteWidget) this widget uses a jquery function which autocompletes a word based on entries from the database. You can preset its initial values by setting prePopulate to a json string in the form ['name': 'some name', 'id': 'some id'] I do this by setting the inital value of the form field to this json string jquery_string = ['name': 'some name', 'id': 'some id'] form = MyForm(initial={'AutoComplete':jquery_string}) When submitting the form the the value of AutoComplete is returned as a comma seperated list of the selected ids e.g. 12,45,43,66 which if what I want. However if there is an error in the form, for example a required field has not been entered the value of the AutoComplete field is now 12,45,43,66 and not the json string which it requires. What is the best way to solve this. I was thinking about overwriting the clean method in the form class but I'm not sure how to find out if any other element has returned an error. e.g. if forms.errors form.cleaned_date['autocomplete'] = json string return form.cleaned_data Thanks

  • Rhino Mocks, Dependency Injection, and Separation of Concerns

    - by whatispunk
    I am new to mocking and dependency injection and need some guidance. My application is using a typical N-Tier architecture where the BLL references the DAL, and the UI references the BLL but not the DAL. Pretty straight forward. Lets say, for example, I have the following classes: class MyDataAccess : IMyDataAccess {} class MyBusinessLogic {} Each exists in a separate assembly. I want to mock MyDataAccess in the tests for MyBusinessLogic. So I added a constructor to the MyBusinessLogic class to take an IMyDataAccess parameter for the dependency injection. But now when I try to create an instance of MyBusinessLogic on the UI layer it requires a reference to the DAL. I thought I could define a default constructor on MyBusinessLogic to set a default IMyDataAccess implementation, but not only does this seem like a codesmell it didn't actually solve the problem. I'd still have a public constructor with IMyDataAccess in the signature. So the UI layer still requires a reference to the DAL in order to compile. One possible solution I am toying with is to create an internal constructor for MyBusinessLogic with the IMyDataAccess parameter. Then I can use an Accessor from the test project to call the constructor. But there's still that smell. What is the common solution here. I must just be doing something wrong. How could I improve the architecture?

  • MATLAB Builder NE crash apppool on IIS 7.5

    - by Alkersan
    Im developing a web user interface for MATLAB functions with ASP.NET. Ive started with studying demos and stucked with such problem. I created a MyComponent.dll assembly with deploytool from MATLAB 2010a, target framework - 3.5. This component has one function GetKnot() which returns a figure. function df = getKnot() f = figure('Visible', 'off'); knot; df = webfigure(f); close(f); end Then I made simple webapp in visual studio 2008 sp1, with only one page Default.aspx. I added references to MWArray.dll, WebFiguresService.dll and MyComponent.dll. The codeBehind is: using System; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using MyComponent; using MathWorks.MATLAB.NET.WebFigures; namespace MATLAB_WebApplication { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { var myComponentClass = new MyComponentClass(); var x = myComponentClass.getKnot(); //WebFigureControl1.WebFigure = new WebFigure(); } } } When I run this page on Visual Studio`s Development web server - everything is fine, figure works. But when I`m trying to deploy webfigure on my local iis 7.5 which runs on Win7 x32 - iis app pool crashes. There is an entry in System Event Log "A process serving application pool 'Classic .NET AppPool' suffered a fatal communication error with the Windows Process Activation Service. The process id was '3676'. The data field contains the error number 6D000780". This happens when MyComponent is instantiating. What I could forget when moved to IIS? Other examples, like magic square console application, runs perfect, and every matlab component instantiating, but not in IIS environment.

  • WPF Navigation Page Breadcrumb

    - by Ryan
    I found code to use a breadcrumb instead of the navigation buttons for my pages. This code works perfect with setting a page as the startup. My problem is that I need to have a window with a frame control as the startup and this is causing the breadcrumb to not show at all. I seem to be missing something with my styling. The types used to be NavigationWindow but I changed them to Frame to try and get a working solution. <Style TargetType="Frame" x:Key="{x:Type Frame}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Frame"> <Grid Background="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="50"/> <RowDefinition Height="50"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <ItemsControl ItemsSource="{Binding RelativeSource={RelativeSource AncestorType={x:Type Frame}}, Path=BackStack}"> <!--Force the ItemsContol to use a wrap panel as Items host--> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <local:InverseWrapPanel KeyboardNavigation.TabNavigation="Cycle" KeyboardNavigation.DirectionalNavigation="Cycle"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <Button Command="NavigationCommands.NavigateJournal" CommandParameter="{Binding RelativeSource={RelativeSource Self}}" Content="{Binding Name}"> <Button.Template> <ControlTemplate TargetType="Button"> <WrapPanel> <TextBlock Name="text1" FontWeight="Bold" Text="{TemplateBinding Content}"/> <TextBlock Name="text2" FontWeight="Bold" Text=">>" Margin="2,0,0,0"/> </WrapPanel> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter TargetName="text1" Property="Foreground" Value="Blue"/> <Setter TargetName="text2" Property="Foreground" Value="Blue"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Button.Template> </Button> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> <AdornerDecorator Grid.Row="2"> <ContentPresenter Name="PART_NavWinCP" ClipToBounds="true"/> </AdornerDecorator> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style>

  • Keyboard Animation Issues When Calling becomeFirstResponder within a Modal View Controller

    - by LucasTizma
    I've been having some issues with calling -becomeFirstResponder on a UITextField contained with a view controller that is presented modally. I call this method in the modal view controller's -viewDidLoad method so that the keyboard is immediately displayed. What I expected is for both the keyboard and the modal view controller to animate from up the bottom of the screen at the same time. However, what I'm observing is the following: There is a ~0.2 second UI lag between clicking the button that calls the -presentModalViewController:animated: method on the parent view controller and when the child view controller begins to animate modally. The keyboard is immediately presented with absolutely no animation about half-way through the modal view controller's animation. Once the modal view controller's animation is complete, everything else seems to operate smoothly. Dismissing the modal view controller results in it being smoothly animated off screen (along with the keyboard, coincidentally). It's as if the keyboard's animation and the modal view controller's animation are both competing for some lower-level Core Animation resource at the same time, but I don't see why this should be happening. What further seems to corroborate this hunch is if I don't ask the UITextField to become the first responder (i.e., if I don't ask the keyboard to present itself), then there is absolutely no UI lag, and the modal view controller animates instantly. Interestingly, if I do something like [self.textField performSelector:@selector(becomeFirstResponder) withObject:nil afterDelay:0.0001]; then the animation of the keyboard happens nearly at the same time as the modal view controller's animation -- it's extremely difficult to tell that they aren't both being animated at the exact same time. Furthermore, there's no more UI lag. Has anyone experienced anything similar to this?

  • WF 4.0 can't get to resume workflow on the staging/production environment

    - by Yasmine Atta Hajjaj
    I have developed various registeration workflows using WF4.0. Each work flow has various bookmarks. I am using the registeration wf for an asp.net application. I tested the asp.net application locally and it is working fine( Starting WF, Persisting to db and resuming bookmarks). When I try to test it on the staging server, everything goes messy. I can no longer resume wfs and I get an error message : System.Runtime.DurableInstancing.InstancePersistenceCommandException was unhandled by user code Message=The execution of the InstancePersistenceCommand named {urn:schemas-microsoft-com:System.Activities.Persistence/command}LoadWorkflow was interrupted by an error. Source=System.Runtime.DurableInstancing StackTrace: at System.Runtime.AsyncResult.End[TAsyncResult](IAsyncResult result) at System.Runtime.DurableInstancing.InstancePersistenceContext.OuterExecute(InstanceHandle initialInstanceHandle, InstancePersistenceCommand command, Transaction transaction, TimeSpan timeout) at System.Runtime.DurableInstancing.InstanceStore.Execute(InstanceHandle handle, InstancePersistenceCommand command, TimeSpan timeout) at System.Activities.WorkflowApplication.PersistenceManager.Load(TimeSpan timeout) at System.Activities.WorkflowApplication.LoadCore(TimeSpan timeout, Boolean loadAny) at System.Activities.WorkflowApplication.Load(Guid instanceId, TimeSpan timeout) at System.Activities.WorkflowApplication.Load(Guid instanceId) at CEO_StartUpCEORegisterationTest.LoadInstance(Guid wfInstanceId) in c:\Users\Kunoichi\Documents\Visual Studio 2010\Projects\CMERegistrationSystem\RegistrationPortal\CEO\StartUpCEORegisterationTest.aspx.cs:line 64 at CEO_StartUpCEORegisterationTest.Page_Load(Object sender, EventArgs e) in c:\Users\Kunoichi\Documents\Visual Studio 2010\Projects\CMERegistrationSystem\RegistrationPortal\CEO\StartUpCEORegisterationTest.aspx.cs:line 44 at System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) at System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) InnerException: System.Data.SqlClient.SqlException Message=Index 'NCIX_KeysTable_SurrogateInstanceId' on table 'KeysTable' (specified in the FROM clause) does not exist.

But I have been banging my head against the wall for more than a week. I did search and all I came to know was to work on ms dtc. I enabled it on the staging server , I installed application server on the staging server and I am still getting the same error. I would appreciate if anyone could help with the problem. Thanks in advance :)
