  • Setting width of UISegmentedControl after removing a segment

    - by David Foster
    I have a UISegmentedControl of width 280. In code, I need to remove the third segment, set the UISegmentedControl's width to 200 and then re-centralise. By configuring the springs and struts in IB, I have set the segmented control up such that when I set the width directly it will automatically re-centre. However, when setting the width in code, is it true I need to set it via -setFrame? If this is the case, then I also need to set its X origin, which renders my auto-centralising redundant. My code: [segmentedControl removeSegmentAtIndex:2 animated:NO]; [segmentedControl setFrame:CGRectMake(segmentedControl.frame.origin.x + ((segmentedControl.frame.size.width - TWO_SEGMENT_SEGMENTED_CONTROL_WIDTH) / 2), segmentedControl.frame.origin.y, TWO_SEGMENT_SEGMENTED_CONTROL_WIDTH, segmentedControl.frame.size.height)]; This works, but seems hugely overblown for my purposes. Is there really no simpler way to set solely the width of the control in code?

  • TFSBuild.Proj and Manual SQL Server Work Help?

    - by ScSub
    Using the VS 2008 GDR update, I have created a database project. I have created a SQL Server deployment package. I have created a database unit test. Using some wizards, the stuff got into my tfsbuild.proj file so near the end of the automated build process a database is created. I lack a little control of the whole process, I now see. What I would like to do is manually deploy the DB, run 3 custom scripts against the DB, and then manually start the DB unit test. I have other non-DB unit tests that already run. I do not want to use VSMDI or ordered unit test stuff because in out multi-developer environment it gets messy. Help!

  • RadControl DateTimePicker Selecting new time doesn't remove highlight from previous selection

    - by Jason Beck
    This is not browser specific - the behavior exists in Firefox and IE. The RadControl is being used within a User Control in a SiteFinity site. Very little customization has been done to the control. <telerik:RadDateTimePicker ID="RadDateTimePicker1" runat="server" MinDate="2010/1/1" Width="250px"> <ClientEvents></ClientEvents> <TimeView starttime="08:00:00" endtime="20:00:00" interval="02:00:00"></TimeView> <DateInput runat="server" ID="DateInput"></DateInput> </telerik:RadDateTimePicker> protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { RadDateTimePicker1.MinDate = DateTime.Now; } }

  • C# Multithreading File IO (Reading)

    - by washtik
    We have a situation where our application needs to process a series of files and rather than perform this function synchronously, we would like to employ multi-threading to have the workload split amongst different threads. Each item of work is: 1. Open a file for read only 2. Process the data in the file 3. Write the processed data to a Dictionary We would like to perform each file's work on a new thread? Is this possible and should be we better to use the ThreadPool or spawn new threads keeping in mind that each item of "work" only takes 30ms however its possible that hundreds of files will need to be processed. Any ideas to make this more efficient is appreciated.

  • Is DataGrid a necessity in WPF?

    - by Jobi Joy
    I have seen a lot of discussions going on and people asking about DataGrid for WPF and complaining about Microsoft for not having one with their WPF framework till date. We know that WPF is a great UI technology and have the Concept of ItemsControl,DataTemplate, etc,etc to make great UX. Even WPF has got a more closely matching control- ListView, which can be easily templated to give better UX than a traditional Datagrid like display. And I would say a readymade DataGrid control will kill or hide a lot of creativity and it surely will decrease the innovations in User Experience field. So what is your opinion about the need of DataGrid in WPF as a Framework component? If you feel it is necessary then is it just because the world is so used to the DatGrid way of data display for many years? Some other threads having the discussion about DatGrid are here and here Link to WPF ToolKit - Latest WPF DatGrid

  • Rendering a derived partial view with Html.RenderPartial

    - by FreshCode
    Calling Html.RenderPartial("~/Views/Payments/MyControl.ascx"); from a view works if Method.ascx is a control that directly inherits System.Web.Mvc.ViewUserControl. However, if the control inherits a new class that derives from System.Web.Mvc.ViewUserControl, the call to Html.RenderPartial("~/Views/Payments/MyDerivedControl.ascx"); fails, reporting that no such view exists. Example derived ViewUserControl: class MyDerivedControl : System.Web.Mvc.ViewUserControl { public Method() { ViewData["SomeData"] = "test"; } } Is there a workaround, or is there another way I should be doing this? Perhaps an HTML helper?

  • How do you exclude folders on get operation for sourcecontrol in CruiseControl.NET

    - by Jon
    I have a cruisecontrol.net project which currently doesn't monitor a source safe project. It is forced manually. Within the source control block however I want to be able to exclude the 'get' operation of a certain folder. I know there is a ExclusionFilter feature on a source control block in the config file, but I think that this excludes the sub folder from being monitored not from being retrieved from the repository. Can anyone confirm this is the case, or help me find out how I can achieve this? I'm using CCNet 1.4 and SourceSafe

  • UiElement from abstract class

    - by plotnick
    I placed a control into a grid. let's say the control is derived from public class 'ButBase' which is derived in its turn from System.Windows.Controls.Button. The code normally compiles and app works just fine. But there's something really annoying. When you try to switch to xaml-design tab it will say 'The document root element is not supported by the visual designer', which is normal and I'm totally okay with that, but the thing is, that all the xaml code is underlined and VS2010 says: 'Cannot create an instance of ButBase' although still normally compiles and able to run. I've tried the same code in VS2008, it said that needs to see a public parameterless constructor in the ButBase, and even after I put one it showed the same error. What do I miss here?

  • 301 versus inline rewrites

    - by Kristoffer S Hansen
    I'm in the process of adding 'pretty' URLs to an existing CMS, the menu is auto generated and the new 'pretty' URLs are to be handled independently as a seperate module. The auto-generated menu allways has URLs that look like this index.php?menu_id=n which ofcourse we would like to see as eg. /news or /products I'm currently at the point where I have to decide if I'm going to rewrite all output of the current system or simply put in a hook where I redirect to the 'pretty' URL. To put it differently, should i connect to the database, fetch all 'pretty' URLs, run through the existing output from WYSIWYG's, news modules, forums etc. and do some str_replace or other string manipulation (which I think would be a rather tedious and boring process), or should I simply hook in and throw a 301 redirecting index.php?menu_id=3 to /news will Google (or other search engines) penalize me for having 301's in the menus?

  • py2app prescripts

    - by yoav.aner
    The py2app documentation mentions prescripts, being run by __boot__.py prior to the main python script. I couldn't find a way to easily specify any prescript on the setup.py file or build process. I did however manage to 'hack' __boot__.py manually and add another _run(prescript) command before my main _run(main_script) and it seemed to work fine. It would however be much better using the standard py2app build process. What I'm essentially trying to do is monkey-patch my sites-packages.zip file prior to the main script being launched. The prescript essentially checks for updates on the server, and if there are any, downloads them, and then overwrites the site-packages.zip file. Much quicker than having to re-install the application from scratch. Any ideas?

  • Whats the KeyCode for overwriting a text in TextBox in winforms

    - by Ragha J
    I have a custom control which extends from TextBox. In the KeyDown event of the control I have access to the KeyCode property of keyEventArgs If the text in the textbox is selected and some other text is typed on top of it, the keyCodes that I am getting in the KeyDown event are different each time and in the KeyPress event I get the actual value. For ex: If the textbox has value 1234 and now I select 1234 and type 5 on top of it, I want to to be able to know in any of the events by some key combination that the old value 1234 is gone and the new value of the textbox is 5.

  • How can I prevent Telerik RadChart from generating an onerror attribute?

    - by Sean McMillan
    We're using the Telerik Rad Controls for ASP.Net Ajax on an ASP.Net MVC project. The RadChart generates the following HTML: <img onerror="if(confirm('Error loading RadChart image.\nYou may also wish to check the ASP.NET Trace for further details.\nDisplay stack trace?'))window.location.href=this.src;" src="ChartImage.axd?UseSession=true&amp;ChartID=e25ad666-e05b-4a92-ac0c-4f2c729b9382_chart_ctl00$MainContent$AverageCTMChart&amp;imageFormat=Png&amp;random=0.501658702968461" usemap="#imctl00_MainContent_AverageCTMChart" style="border-width: 0px;" alt=""> I'd like to remove the onerror attribute; I don't really want the customers being offered the option to see a stack trace if something goes wrong. I can't see any way to control the markup that this control generates. Google searches provide no help. Has anyone dealt with this before? How do I remove the onerror attribute?

  • Keyboard Simulation not working with Keyboard hook for modifier keys

    - by Eduardo Wada
    I have a piece of software that is being used to simulate a certain device on a touchscreen, this device already runs an application that receives keyboard input from the device. My software (reffered to as simulator) displays a virtual keyboard and runs the application. Thus, the simulator sends keys with input simulator: http://inputsimulator.codeplex.com/ And the applciation listens to keys with the following keyboard hook: https://svn.cyberduck.io/tags/release-4-1/source/ch/cyberduck/core/GlobalKeyboardHook.cs My problem is, what some keys from the device's hardware actually do is to sent a key combination (ex: left-alt + 1) to the application and a weird scenario is occurring: The application listens to normal keyboard inputs The simulator sends keys to other applications (ie: visual studio responds to the keys sent when debugging) The simulator can send single keys to the application (I can type) The simulator CANNOT send key combinations to the application (alt+1 is received as just 1 in the application) This started happenning when we imported the application's dll into the same process from the simulator. Could there be any reason why I can't simulate key combinations for a hook in the same process? Is there any easy fix for this?

  • Using GridSplitter in a Xaml file for both Silverlight and WPF

    - by Daniel Plaisted
    I have a Xaml file which is used in a project which can be built for both Silverlight and WPF. I want to use the GridSplitter control. However, this control is in different Xaml namespaces on Silverlight and desktop WPF. In WPF, the namespace is: http://schemas.microsoft.com/winfx/2006/xaml/presentation On Silverlight, it is: http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk So if the xaml code is <GridSplitter/>, it will work on WPF but not Silverlight, and if the code is <sdk:GridSplitter/>, it will work on Silverlight but not WPF. Is there a way to write this so that it works on both platforms?

  • What's the best way to create a Windows Mobile application with multiple screens in C#

    - by Joseph Earl
    I am creating a Windows Mobile Application in C# and Visual Studio 2008. The application will have 5-6 main 'screens'. There will also be bar (/area) with information (e.g. a title, whether the app is busy, etc) above the screens, and a toolbar (or similar control) below the screens with 5-6 buttons (with images) to change the active screen (i.e. the screens will share the top bar and toolbar) What is the best way to implement this? Use multiple forms, and just include the toolbar and top-bar in each Use a single form and something like the Tab control (but customised) to contain the screens Something else? Keeping in mind a) memory usage and b) time to switch screens. Thanks in advance. Any links, pointers etc are much appreciated.

  • Nice shadow effect in text (UISegmentedControl)

    - by Matthias
    Hi, I would like to bring some color to the texts of my UISegmentedControl. So, I've searched a bit about this topic, but it seems to be not possible out-of-the-box. But I found this nice blog post (link text), how to build an image out of a custom text and then assign it to the segemented control. Works fine, but the text in these created images do not have this nice little shadow effect as the original ones. So, does anyone know, how to create such a shadow effect? I guess, Apple does the same (building an image for the text) with the standard segmenented control. Thanks for your help. Regards Matthias

  • MapViewOfFile shared between 32bit and 64bit processes

    - by MK
    Hi, I'm trying to use MapViewOfFile in a 64 bit process on a file that is already mapped to memory of another 32 bit process. It fails and gives me an "access denied" error. Is this a known Windows limitation or am I doing something wrong? Same code works fine with 2 32bit processes. The code sort of looks like this: hMapFile = OpenFileMapping(FILE_MAP_ALL_ACCESS, FALSE, szShmName); if (NULL == hMapFile) { /* failed to open - create new (this happens in the 32 bit app) */ SECURITY_ATTRIBUTES sa; sa.nLength = sizeof(SECURITY_ATTRIBUTES); sa.bInheritHandle = FALSE; /* give access to members of administrators group */ BOOL success = ConvertStringSecurityDescriptorToSecurityDescriptor( "D:(A;OICI;GA;;;BA)", SDDL_REVISION_1, &(sa.lpSecurityDescriptor), NULL); HANDLE hShmFile = CreateFile(FILE_FAXCOM_SHM, FILE_ALL_ACCESS, 0, &sa, OPEN_ALWAYS, 0, NULL); hMapFile = CreateFileMapping(hShmFile, &sa, PAGE_READWRITE, 0, SHM_SIZE, szShmName); CloseHandle(hShmFile); } // this one fails in 64 bit app pShm = MapViewOfFile(hMapFile, FILE_MAP_ALL_ACCESS, 0, 0, SHM_SIZE);

  • creating new usercntrols at runtime in ASP.NET MVC

    - by Paul Connolly
    Hi everyone, My situation is that the user is creating an entity on my site which contains the particlars of the driectors of that company, name address etc.. The Director form is a separate user control with the appropriate textboxes etc. At run time we don't know how many of these directors there will be so I need one to be able to use something like an "ADD DIRECTOR" or "DELETE DIRECTOR" button which will present or delete the another usercontrol to add the additional director. Currently I am trying to make this happen within a pane of the JQuery Accordion control. I have looked many places for how to do this but to no avail. Can anyone tell me where I might find some inforamation about how I can do this? All the best Paul

  • Loading dynamic content and rewrite URL on Hashchange event with Jquery Mobile

    - by user3611500
    I'm building a mobile version for my website using Jquery Mobile API. The framework provides automate AJAX navigation processing. But as far as i know it require "real" pages for loading purpose. What i want to do is override the automate navigation process of it and process the hashchange on my own. But i can't not rewrite the url using window.hashChange, which is running well on my non-mobile website version : $(function () { $(window).off().hashchange(function () { if (location.hash.length > 1) { PageSelect(); } }); $(window).hashchange(); }); I just only want to take advantage on jquery mobile interfaces, i don't want anything with its automate ajax navigation stuff ! I tried to disable it using ajaxEnabled() but got no luck.

  • .NET: IOException for permissions when creating new file?

What am I doing wrong here? UPDATE: This code throws the same exception: StreamWriter writer = new StreamWriter(Path.Combine(PATH_TO_DATA_DIR, fileName)); UPDATE 2: The file I am trying to create does not exist in the file system. So how can be it in use?
