  • How to let parent control know that its child got focus?

    - by Axarydax
    Hi there, imagine that I have a Form with 9 controls (TabbedStuffControl) in a 3x3 tile, and these controls contain TabControls containing another control (StuffControl) with ListBoxes and TextBoxes. I'd like to know a proper way to let TabbedStuffControl that its child has received a focus? e.g. user clicks into a textbox of StuffControl or drags something to listbox of StuffControl. Eventually the Form should know which TabbedStuffControl is active Do I need to hook up GotFocus event of TextBoxes and ListBoxes and TabControls, then dispatch another event to finally let Form know who got focus? I think that there should be a simpler way - that somehow TabbedStuffControl knows that its child got focus, so there would be only one place in code that I'll hook up. Thanks.

  • how to use multiple tab controls, and to be able to call a selected tab control with buttons.

    - by mojotaker
    Please I am trying to assign each button on the left its own Tab control. That is for example, when the Intake form button is pushed, it will have its own set of tabs (its own tabcontrols) am i supposed to place multiple tab controls on the artboard, or is there a way to programatically change the names of the tabs, and there contents, when a button is pushed on the left ? thank you in advance. and here is a link hxxp://img709.imageshack.us/img709/554/tabcontrol.gif here is the code so far <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" x:Class="service.MainWindow" x:Name="Window" Title="MainWindow" Width="687" Height="480" mc:Ignorable="d"> <Window.Resources> <Storyboard x:Key="OnLoaded1"/> </Window.Resources> <Window.Triggers> <EventTrigger RoutedEvent="FrameworkElement.Loaded"> <BeginStoryboard Storyboard="{StaticResource OnLoaded1}"/> </EventTrigger> </Window.Triggers> <Grid x:Name="LayoutRoot" Margin="0,0,-16,1"> <Grid.ColumnDefinitions> <ColumnDefinition Width="0*"/> <ColumnDefinition/> </Grid.ColumnDefinitions> <DockPanel Margin="8,8,0,7" LastChildFill="False" Grid.Column="1" HorizontalAlignment="Left" Width="660"> <Menu VerticalAlignment="Top" Width="657" Height="32"> <MenuItem x:Name="file" Header="File"/> <MenuItem x:Name="edit" Header="Edit"> <MenuItem Width="100" Height="100" Header="MenuItem"/> </MenuItem> <MenuItem x:Name="view" Header="View"/> <MenuItem x:Name="preferences" Header="Preferences"/> <MenuItem x:Name="help" Header="Help"/> </Menu> </DockPanel> <TabControl x:Name="tabwin" Margin="137.224,46,19,7" Grid.Column="1"> <TabItem x:Name="intakeformsub" Header="Elegibility Form"> <Grid HorizontalAlignment="Left" Width="490"/> </TabItem> <TabItem Header="TabItem"> <Grid/> </TabItem> <TabItem Header="TabItem"> <Grid/> </TabItem> <TabItem Header="TabItem"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="0.567*"/> <ColumnDefinition Width="0.433*"/> </Grid.ColumnDefinitions> </Grid> </TabItem> <TabItem Header="TabItem"> <Grid/> </TabItem> <TabItem Header="TabItem"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="0.735*"/> <ColumnDefinition Width="0.265*"/> </Grid.ColumnDefinitions> </Grid> </TabItem> <TabItem Header="TabItem"> <Grid/> </TabItem> <TabItem Header="TabItem"> <Grid/> </TabItem> </TabControl> <Grid x:Name="___buttontab" Margin="11.205,61,0,0" Grid.Column="1" HorizontalAlignment="Left" Width="122.019" VerticalAlignment="Top" Height="276"> <Button VerticalAlignment="Top" Height="36" Content="Button"/> <Button Margin="0,40,0,0" Content="Oasis Assessments" VerticalAlignment="Top" Height="36"/> <Button Margin="0,80,0,0" VerticalAlignment="Top" Height="36" Content="Plan of Care"/> <Button Margin="0,120,0,0" VerticalAlignment="Top" Height="36" Content="Medication Profile" RenderTransformOrigin="0.421,5.556"/> <Button Margin="0,0,0,80" VerticalAlignment="Bottom" Height="36" Content="Clinical Notes"/> <Button Margin="0,0,0,40" VerticalAlignment="Bottom" Height="36" Content="Infection Control"/> <Button x:Name="intakeformbtn" VerticalAlignment="Top" Height="36" Content="Intake Form" Click="intakeform"> <Button.BindingGroup> <BindingGroup/> </Button.BindingGroup> </Button> <Button VerticalAlignment="Bottom" Height="36" Content="Discharge Summary"/> </Grid> <ProgressBar HorizontalAlignment="Left" Margin="8,0,0,7" VerticalAlignment="Bottom" Width="104.795" Height="19" Grid.Column="1"/> </Grid> </Window>

  • Which Win32 API reports the Format preference in the Region and Language control panel?

    - by Integer Poet
    Windows 7 and Windows Vista have a Region and Language control panel which contains a Formats tab which contains a popup menu titled Format. This menu allows the user to select from among many language-oriented sets of number, currency, time, and date formatting preferences regardless of the language of the base system. For example, I could decide I prefer the default currency symbol to be Japanese yen on a US English system. The Windows Contacts application changes its behavior depending on these format preferences. For example, if I select Japanese formatting preferences, Windows Contacts displays and lets me edit phonetic names (AKA "ruby", "yomi", and "furigana") but not middle names. If I select US English formatting preferences, Windows Contacts displays and lets me edit middle names but not phonetic names. I need to write code (native C calling Win32) which mirrors the behavior of the Windows Contacts application in this respect. Which API should I call?

  • How to control a NSView, located in a dedicated NSWindow, from the main NSWindow designed to support

    - by Michael
    Hi, This is probably a simple problem for the high skilled Cocoa programmers, but I can't find how to control the graph in a separate window. I read carefully the Cocoa related books, go through many web notes,but I can't find a solution to my problem. The purpose is to use a dedicated window to draw the I=F(Vg) curves extracted by the GUI from a specific hardware. All the GUI and the hardware works fine ( thanks to the help provided by several members of stackoverflow) , but no way to send the parameters to the NSView to display the results. So far, the GUI class is based on a NSObject, the graphic class is NSView. Any idea, examples, links will be appreciated. Thank you so much. Michael

  • Using axWebBrowser control to capture page request and postdata.

    - by Arjo
    I'm writing a small utility to capture all requests made to a web server from a windows application using the axWebBrowser control. So far I have the following working, as the user traverse the website clicking on links, posting forms etc I capture the webpage and the data being send to the server to request the next page. Where I run into a stumbling block is when it comes to Ajax calls. There are number of drop down boxes that filter down the selection as the user types in the search term, I would like to capture the page/script that is called and the data being send. Any hint, advice would be greatly appreciated.

  • Set property on usercontrol that can be used in custom panel in control... Silverlight

    - by Dimestore Cowboy
    I have a simple usercontrol that uses a simple custom panel where I just overrode the Orientation and Measure functions. What I want to do is to have a property in the usercontol to control the orientation So I basicaly have UserControl -- Listbox -- MyPanel And I want a property for the usercontrol that can be set in xaml (of type System.Windows.Controls.Orientation ) that I can bind to from my custom panel (or a different approach if binding isnt the right way to do it) It would be a bonus if that property could show up in the properties window and you could select vertical or horizontal. And a super bonus if I could change the property at design time and have the listbox/

  • Can I resolve ASP.NET "~" app paths to the website root without a Control being present?

    - by jdk
    I want to Resolve "~/whatever" from inside non-Page contexts such as Global.asax (HttpApplication), HttpModule, HttpHandler, etc. but can only find the Resolution methods specific to Controls (and Page). I think the app should have enough knowledge to be able to map this outside the Page context. No? Or at least it makes sense to me it should be resolvable in other circumstances, wherever the app root is known. Update: The reason being I'm sticking ~ paths in the web.configuration files. Update 2: I'm trying to resolve them to the website root such as Control.Resolve(..) URL does, not to a file system path.

  • How would I go about building a calendar UI control for the iPhone/iPad?

    - by BeachRunnerJoe
    Hello. There are a few different 3rd party code frameworks that include calendar controls, but most of them have a lot of functionality I don't need, plus most of them lack sufficient documentation on how to use them and I'm not a proficient enough iPhone developer figure it out using just the code. So I'm going to attempt to build my own and I was hoping you could provide me with some high-level direction to get started. At a high level, how could I build a simple, calendar control that doesn't do much more than display a calendar (month view, with the current date highlighted) and allows the user to selected a date? Something that looks like the calendar in the upper right corner of this image... Thanks so much in advance for your help!

  • Is ASP.Net Server Control, Postback Architecture failed in current Web 2.0 World.

    - by Lalit
    What i am looking around me is the drastically change in ASP.Net Architecture. More and more company are following the approach of JSON based wcf service in middle tier. Plain HTML based UI tier with JQuery/Ajax. No Postback at all, This contradicts the Default behaviour of Asp.Net Server Control/Code Behind Event handler/Postback. I am a Asp.Net Web Developer for around 4 years, and concerned about the future of ASP.Net. Is the Default Architecture of ASP.Net is Outdated at all? Does MVC or ASP.Net 4.0 Tries to solve the Issue?

  • Why do Pascal control structures appear to be inconsistent?

    - by 70Mike
    Most Pascal control structures make sense to me, like: for ... do {statement}; if (condition) then {statement}; while (condition) do {statement}; where the {statement} is either a single statement, or a begin ... end block. I have a problem with: repeat {statement-list} until (expression); try {statement-list} except {statement-list} end; Wouldn't it be better that repeat and try have the same general structure, accepting only a single statement or a begin ... end block, instead of having a statement-list that's not formally blocked with a begin and an end?

  • C#.NET How to access fields in user control dynamically?

    - by Conor H
    Hi, I'm making a settings screen at the moment that will have a radiobutton group which will determine what controls are displayed. The different settings are contained within a UserControl. I am dynamically creating this UserControl like so: panel = new btSettings(); this.Controls.Add(panel); panel.Location = new Point(15, 49); Just wondering how I can access the fields within this control and design time when the object will only be created during run time? Thanks.

  • Should I use custom exceptions to control the flow of application?

    - by bonefisher
    Is it a good practise to use custom business exceptions (e.g. BusinessRuleViolationException) to control the flow of user-errors/user-incorrect-inputs??? The classic approach: I have a web service, where I have 2 methods, one is the 'checker' (UsernameAlreadyExists()) and the other one is 'creator' (CreateUsername())... So if I want to create a username, I have to do 2 roundtrips to webservice, 1.check, 2.if check is OK, create. What about using UsernameAlreadyExistsException? So I call only the 2. web service method (CrateUsername()), which contains the check and if not successfull, it throws the UsernameAlreadyExistsException. So the end goal is to have only one round trip to web service and the checking can be contained also in other web service methods (so I avoid calling the UsernameAlreadyExists() all the times..). Furthermore I can use this kind of business error handling with other web service calls completely avoiding the checking prior the call.

  • How can you determine if Control.Visible is set via property or if the value is inherited

    - by JDMX
    I need to find a way to determine if the Visible property of a control is set via a property change or if is inheriting it value from its parent. Using the Reflector, I find that the functions this.GetVisibleCore() and this.GetState() are both internal methods so I cannot call them. The widgets themselves are created dynamically so I do not want to attach a method to the VisibleChanged event just after the creation of each widget so can try to monitor this property. If I have to, I guess I will but I am looking for something jsut a bit more elegant.

  • How to control the memory size of continuously running windows service?

    - by Snowill
    Hi, I have created a windows service which is continuously polling a database. For this purpose i have a timer in place. Ever time i am querying a database table i open a connection and close it immediately after my work is done. Right now i am doing this every 20 seconds for testing purpose, but later this time might increase to 5 - 10 minutes. What happens is everytime the database table is polled there is an increase of 10-12 KB in the size of the memory of the service running. This i can see in the task manager. Is there any way to control this.

  • "Thread-Safe Calls" with "Invoke" method to Winform control leads very heavy memory leak!!

    - by konnychen
    In the following link: "Make Thread-Safe Calls to Windows Forms Controls http://msdn.microsoft.com/en-us/library/ms171728.aspx" We can see an example which provide cross tread access to a winform control. But if the thread is in a while loop, it will cause the heavy memory leak. As I use taskmanage I can see the memory is increasing. Can anyone help me to solve the problem? oThread2 = new Thread(new ThreadStart(Cyclic_Call)); oThread2.Start(); delegate void SetText_lab_Statubar(string text); private void m_SetText_lab_Statubar(string text) { if (this.lab_Statubar.InvokeRequired) { SetText_lab_Statubar d = new SetText_lab_Statubar(m_SetText_lab_Statubar); this.Invoke(d, new object[] { text }); } else { this.lab_Statubar.Text = text; } } private void Cyclic_Call() { do { this.m_SetText_lab_Statubar("This string is set from thread"); Thread.Sleep(100); } while (!b_AbortThraed); }

  • Slider with keypress control bugs when keys pressed to quickly.

    - by Jaybuz
    Hello, I've made a slider that uses the left and right arrow keys to move the slide but when pressed to quickly it will bug a little and I was wondering if it's possible to limit the amount of presses in say a second. You can see it here: {link} $('#slider-nav div').click(function() { $('#slider-nav div').removeClass('selected').addClass(''); $('#slider-nav div:eq('+($.jcarousel.intval($(this).text())-1)+')').addClass('selected'); }) // Allow left and right keys to control slider $(document.documentElement).keypress(function(e) { var code = (e.keyCode ? e.keyCode : e.which); var direction = null; // handle cursor keys if (code == 37) { // left key direction = 'prev'; } else if (code == 39) { // right key direction = 'next'; } if (direction != null) { $('#slider-nav div.selected')[direction]().click(); } });

  • Possible to InvalidateVisual() on a given region instead of entire WPF control?

    - by Scott Bilas
    I have a complex WPF control that draws a lot of primitives in its OnRender (it's sort of like a map). When a small portion of it changes, I'd only like to re-issue render commands for the affected elements, instead of running the entire OnRender over. While I'm fine with my OnRender function's performance on a resize or whatever, it's not fast enough for mouse hover-based highlighting of primitives. Currently the only way I know how to force a screen update is to call InvalidateVisual(). No way to send in a dirty rect region to invalidate. Is the lowest granularity of WPF screen composition the UI element? Will I need to do my renders of primitives into an intermediate target and then have that use InvalidateVisual() to update to the screen?

  • Plastic SCM vs. Mercurial? Need Source Control for Visual Studio 2005 on Windows 7

    - by Pete Alvin
    1) Has anyone used Plastic SCM? Is it reliable? 2) How does it compare with Mercurial? (It seems like this is a good candidate for DVCS on Windows. I tried Git and really didn't like it.) 3) I really like TortoiseSVN. I like a central model because of the piece of mind that if it's in the respository it's "safe" and tracked. Here is the question: Is the excitement over distributed version control (DVCS) worth the hype? My environment: Windows 7 Windows development (Dev. Studio 2005, SQL Server 2003); integration would be nice Two developers sharing same code push code to production servers almost daily

  • Is there a way to allow a property of a user control to be modified only during design time?

    - by Dan
    I've looked into the DesignOnly attribute, but that doesn't seem to accomplish what I want*. Basically, I'm looking for some way to indicate that some property of a user control (let's say Text) can be modified during design time -- i.e., from the Windows Forms designer in VS (or presumably from any GUI designer that can be used to modify a Windows Forms GUI) -- but not during run time. Once the application is running, the property should effectively be readonly. Is this possible? * When I add the DesignOnly attribute to a property, the value I select for that property from design mode doesn't seem to stick; the property just ends up being whatever I have it set to by default in code.

  • How do I retrieve readonly values when using a DetailsView control to update a record?

    - by lincolnk
    I'm using a detailsview control to update a record, however in this particular case there's only one field that can be changed out of a many. The update method for my object takes all fields as parameters. When the detailsview's updating method fires, the values for the readonly fields (those rendered as a Label) are not available in the e.NewValues collection. I'm currently grabbing a reference to the object when the detailsview is databound (in the objectdatasource selected event handler), storing it in session and manually adding entries to the e.NewValues collection when updating fires. It works but seems kind of heavy handed. So, is there a better way to get the read only values back into my update method? Or is there a better way of doing this altogether?

  • How do I stop server control attributes being HTML encoded?

For example: linkBooks.Attributes("onmouseover") = "changeImages(""books"", ""/images/common/books-dark.png""); return true;" Gets converted to: onmouseover="changeImages(&quot;books&quot;, &quot;/images/common/books-dark.png&quot;); return true;" How do I prevent this? The same code worked fine under VS2005 and .NET 2.0, I'm currently using VS2010RC and .NET 4.0.
