  • How do I keep Visual Studio's Windows Forms Designer from deleting controls?

    - by Sören Kuklau
    With several forms of mine, I occasionally run into the following issue: I edit the form using the designer (Visual Studio 2008, Windows Forms, .NET 2.0, VB.NET) to add components, only to find out later that some minor adjustments were made (e.g. the form's size is suddenly changed by a few pixels), and controls get deleted. This happens silently — event-handling methods automatically have their Handles suffix removed, too, so they never get called, and there's no compiler error. I only notice much later or not at all, because I'm working on a different area in the form. As an example, I have a form with a SplitContainer containing an Infragistics UltraListView to the left, and an UltraTabControl to the right. I added a new tab, and controls within, and they worked fine. I later on found out that the list view's scrollbar was suddenly invisible, due to its size being off, and at least one control was removed from a different tab that I hadn't been working on. Is this a known issue with the WinForms Designer, or with Infragistics? I use version control, of course, so I can compare the changes and merge the deleted code back in, but it's a tedious process that shouldn't be necessary. Are there ways to avoid this? Is there a good reason for this to occur? One clue is that the control that was removed may have code (such as a Load event handler) that expects to be run in run time, not design time, and may be throwing an exception. Could this cause Visual Studio to remove the control?

  • Resharper doesn't play well with XAML?

    - by John Weldon
    I've been noticing a pattern with ReSharper (both 4.5 and 5). Very often (almost always) when I have solution-wide analysis turned on, and WPF code in my solution, ReSharper will mark a number of the .xaml.cs files as being broken. When I navigate to the file, sometimes it magically updates and displays no errors, and other times I have to open other files that are not being correctly read and close them again to force resharper to correctly analyze them. I assume it has something to do with the temporary .cs code that is generated with XAML, but does anyone know why this is actually happening, and if there is a work around? Should I just file a bug report with JetBrains? Does anyone else experience this?

    Hi, I'm trying to set up my developing environment using Visual Studio 2008 to develop for the UNO-1019. I managed to connect the UNO to VS for deployment and debug using the ethernet connection. I installed the SDK for EVC++ available on the products page and I was wondering if I can use that sdk on visual studio 2008.I'm rather new with this and I's kind of lost. Thanks in advance

  • How to handle CSS relative paths in an ASP.NET MVC application.

    - by AngryHacker
    I have a master page, which has a style sheet, which has the following line: .idle { background-image: url( '../../Images/blue_bg.png' ); } All my pages inherit from this master page. And this works well when the URL is http://www.domain.com/home/details/5, however the URL is http://www.domain.com/home/create, then, of course, blue_bg.png cannot be found because `../../Images/blue_bg.png' resolves to a directory one higher where there is nothing there. I tried the trick suggested by @codemeit in a similar question, but I can't plop down C# in a style sheet, can I? How is this typically handled?

  • How to speed up loading the splash screen.

    - by AngryHacker
    I am optimizing the startup of a WinForms app. One issue I identified is the loading of the splash screen form. It takes about half a second to a second. I know that multi-threading is a no-no on UI pieces, however, seeing how the splash screen is a fairly autonomous piece of the application, is it possible to somehow mitigate its performance hit by throwing it one some other thread (perhaps in the way Chrome does it), so that the important pieces of the application can actually get going.

  • Need Simple way to access XML in VB.Net - Pain with Linq-to-Xml

    - by aiart
    Dim myXDoc As XDocument = _ I want to access this in a simple way in VB.Net - Like: Dim Integer SizeXStr = CInt(MyZDoc.Cameras(1).Camera_Desc.@SizeX) ' where (1) is an index Why isn't this implemented in VB.Net? Better yet, type the values with a Schema and eliminate the conversion. Is this so hard? How do I access, in a simple way, data in XML - this would be VERY VERY useful! I have been using Query to try to get the values - when I use MsgBox() to display results, they display, but my main Windows Form is Trashed - changed colors, etc. The system has Bugs. Instead, I have to create an elaborate structure of arrays of objects and read the XML line-by-line and do the same for saving - this is the dark ages. Art

  • Redraw and flicker issues

    - by AngryHacker
    I have an Outlook style app. So basically I have a sidebar on the left and on the right I have a panel control (pnlMainBody) that hosts content. The content is typically a user control that I add to the panel when user clicks appropriate button in the side bar. The way I add the user control to the panel is as follows: // _pnlEmails is the User Control that I am adding to the panel _pnlEmails = new pnlEmails(); _pnlEmails.Dock = DockStyle.Fill; this.pnlMainBody.Controls.Add(_pnlEmails); Some of the user controls that I add to the main panel are quite complex UI-wise. So when this.pnlMainBody.Controls.Add(_pnlEmails); fires, I see the control appear on the screen, then it resizes itself to fill the body of the panel control. It's quite ugly actually, so I was wondering whether there is a way to not show the resizing until it's actually done resizing? I've tried setting the user control's .Visible to false. I've tried doing .SuspendLayout, all to no avail. Is there a way to do this so the screen transitions are smooth?

  • Spring.net is not injecting chained base class properties!

    - by JohnIdol
    I am successfully injecting base class properties with spring.net with just a class that inherits from a base abstract class. Lets say Class MyClass : MyBase, and I am successfully setting a property like this: <object id="myInstantiableClass" type="myAssembly.MyClass myAssenbly" abstract="true"> <property name="MyBaseClassProperty" ref="anotherObjRef"></property> </object> Where MyBaseClassProperty is a property on the base class. Now I have another abstract class between the old base class and the instantiable class, and I am trying to set properties on both the abstract classes. So MyClass : MyNewBaseClass, and MyNewBaseClass : MyBaseClass. I have an additional property on the new base class (MyNewBaseClassProperty) and I am trying to inject it like this: <object id="myInstantiableClass" type="myAssembly.MyClass myAssenbly" abstract="true"> <property name="MyBaseClassProperty" ref="anotherObjRef"></property> <property name="MyNewBaseClassProperty" ref="someOtherObjRef"></property> </object> The property on the old base class is being injected but the one on the new one is not - and I am not getting an error or anything (so I am pretty sure my config is good), that property is just null! Any help appreciated! P.S. I am on asp.net (not MVC) but I don't think it's related.

  • Performance implications of BeginInvoke

    - by AngryHacker
    I've inherited code where BeginInvoke is called from the main thread (not a background thread, which is usually the pattern). I am trying to understand what it actually does in this scenario. Does the method being called in the BeginInvoke get in line of messages that come down to the window? The docs say asynchronously, so that is my assumption. How does the framework prioritize when to kick off the method called by BeginInvoke?

    i have successful created asp.net web deployment project under visual studio 2008 and everything works fine. However there is a new requirement from my user where they want to browse the location to install the web application instead of using the default install location. Is there anyway to achieve this ? or do i need to use some third party deployment tools? i have tried the sample transformation file on http://www.codeproject.com/KB/install/ChangeVDirWebSetupProject.aspx?fid=295594&fr=1&df=90&mpp=25&noise=3&sort=Position&view=Quick#xx0xx but it only seems to work under vs2005 thanks

  • Convert File System Website to IIS Website

    - by Noah
    We recently migrated from VS 2008 to VS 2010. The migration went fine, except for our web project. Before, in VS 2008, the site showed up as http://localhost/Website. Now, it appears as C:...\Website. It appears that when we did the migration, VS started to treat it as a file system website. I've tried removing the existing site and re-adding it as an existing website, but it still displays it as C:...\Website. Is there any way to convert it back to show it as a http://localhost/website, and run through IIS, as opposed to the default ASP.NET Development Server?

  • VB.Net Application Settings / ClickOnce

    - by B Z
    VS 2008 / VB.Net / WinForms I have an application setting (Settings.settings) for a project and I am using Click Once deployment. I used the VS Editor to create the setting and I can see the setting in the app.config file <applicationSettings> <MyApp.Win.My.MySettings> <setting name="MySetting" serializeAs="String"> <value>False</value> </setting> </MyApp.ArtTracker.Win.My.MySettings> </applicationSettings> I would like to update this setting after the application is compiled. The setting is for testing purposes only. If I change the xxx.config.deploy and I reinstall the app with click once. The new setting value doesn't change (seems to be cached somewhere). Even if I change in my local pc the setting seems to be cached somewhere. If I go in VS it asks me to Re-Sync the settings. But I need to do this after the application is compiled. Thanks for any help

  • How to troubleshoot dependencies not copying.

    - by AngryHacker
    I have an EXE project A, which references a class library project B (all in the same solution). Project B has a reference to about 10 3rd party DLLs (from DevExpress). All the referenced assemblies have Copy Local set to true. When I build the entire solution, the resulting DLL from project B is copied into the bin/debug of project A. However, none of the dependencies of project B get copied. I looked in the Output window during compile and all looks good. There aren't any errors. How do I troubleshoot this?

    I want to create a custom ribbon button within Outlook 2007 using Visual Studio 2008 Standard, but am unsure how to proceed.

Is creating custom ribbon buttons possible using Visual Studio 2008 Standard? If so, where should I start?
