• Page containing Microsoft Chart Control returns Service Unavailable

  - by MHinton

  I have a frustrating problem with an asp.net mvc view containing the Microsoft Chart control. When I request the view containing the control I get the following error. Service Unavailable HTTP Error 503. The service is unavailable. When I run the project under the visual studio 2008 dev server it works fine. When I deploy the project to the staging server I get the error. To make this even more frustrating when I deploy to a different site on the same server under a virtual directory it works. I also get no error messages in the event log or elmah when this happens. Has anyone else encountered this? What did you do to resolve it?

• Table and Column names causing problems

  - by craig

  I have an issue when the T4 linq templates generate the classes for my MySql db using subsonic 3. It looks like one of our table names "operator" is causing problems in the Context.cs generated class. In the following line of code in Context.cs Visual Studio sees <operator> as a c# operator and generates a compilation error of "Type expected" public Query<operator> operators { get; set; } Is there anyway I can work around this without having to rename my database table and column names? For example hard coding something in Settings.ttinclude to use or map different names to specific db tables and columns?

• Which C# / .NET free or standard bits and pieces do I need to make a simple Windows desktop app back

  - by jjujuma

  I'm coming from a Java / web background with no C# experience and I want to write a prototype C# / .NET desktop app to run against my existing DB2 database. The idea is that the prototype should use libraries and tools which are suitable for scaling up to full production and should be standard and free. Of the top of my head, the two biggest things I need are: an IDE a GUI toolkit / set of components a JDBC equivalent and/or possibly a full blown ORM system What are my options? Note I don't mind paying for full blown Visual Studio in the long run, but for now everything needs to be free, including the IDE.

  - by Jayesh

  Hi, I have been working on a Silverlight app that consumes a WCF service. [on Visual Studio] as a matter of simplicity I created a WCF service in the project itself [as-in I didnt host it in IIS, but let the build-in webdev server in VS do it for me] It works well, now I want to deploy it on IIS 7.0, can you tell me If i would need to host the service independently and then the remaining stuff or if I just publish the website, the service would be hosted too and the Silverlight client would be able to communicate with the service. Please help! Thanks

  I am using the new free .net chart controls and they appear to work fine when I run the project up in visual studio, but when hitting the same via IIS I get and exception: [HttpException (0x80004005): No http handler was found for request type 'GET'] System.Web.HttpApplication.MapIntegratedHttpHandler(HttpContext context, String requestType, VirtualPath path, String pathTranslated, Boolean useAppConfig, Boolean convertNativeStaticFileModule) +529 System.Web.HttpServerUtility.Execute(String path, TextWriter writer, Boolean preserveForm) +947 [HttpException (0x80004005): Error executing child request for ChartImg.axd.] System.Web.HttpServerUtility.Execute(String path, TextWriter writer, Boolean preserveForm) +4120098 System.Web.UI.DataVisualization.Charting.ChartHttpHandler.EnsureInitialized(Boolean hardCheck) +266 System.Web.UI.DataVisualization.Charting.Chart.GetImageStorageMode() +25 System.Web.UI.DataVisualization.Charting.Chart.Render(HtmlTextWriter writer) +133 System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) +240 System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) +240 System.Web.UI.HtmlControls.HtmlForm.RenderChildren(HtmlTextWriter writer) +253 System.Web.UI.HtmlControls.HtmlForm.Render(HtmlTextWriter output) +87 System.Web.UI.HtmlControls.HtmlForm.RenderControl(HtmlTextWriter writer) +53 System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) +240 System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) +240 System.Web.UI.Page.Render(HtmlTextWriter writer) +38 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +4240 Any idea what I'm doing wrong?

• how to: re-assemble machine generated classes from xsd files to their original nested state.

  - by Paul Connolly

  Hi everyone, I'm working in Visual Studio 2008 using c#. Let's say I have 2 xsd files e.g "Envelope.xsd" and "Body.xsd" I create 2 sets of classes by running xsd.exe, creating something like "Envelope.cs" and "Body.cs", so far so good. I can't figure out how to link the two classes to serialize (using XmlSerializer) into the proper nested xml, i.e: I want: <Envelope><DocumentTitle>Title</DocumentTitle><Body>Body Info</Body></Envelope> But I get: <Envelope><DocumentTitle>Title</DocumentTitle></Envelope><Body>Body Info</Body> Could someone perhaps show me how the two .cs classes should look to enable XmlSerializer to runt the desired nested result? Thanks a million Paul

• Outlook 2003 Add-In Setup Project with COM DLL Deployment Problem

  - by Malkier

  Hi, I developed an Outlook 2003 add-in which uses the com dll redemption. I created a visual studio 2008 setup project, added a custom action to run "caspol.exe -machine -addgroup 1 -strong -hex [key] -noname -noversion FullTrust -n \"Name\" -description \"desc\" and moved the registry keys under software to HKLM as described in http://msdn.microsoft.com/en-us/library/cc136646.aspx#AutoDeployVSTOse_InstallingtheAddinforAllUsers to ensure all-users compatibility. I included the redemption.dll in the setup with vsdrfCOMSelfReg (vsdrfCOM throwed an error). My problem is: When installing the setup on a test machine under an admin account, it runs fine under all users, however when we use the company wide software deployment which runs under a system account the setup executes but the add-in wont load. If I repair the installation with an admin account again it loads just fine. Shouldn't a system account have the required permissions to install all of the components? What options do I have? Thanks for any suggestions.

• Is it possible to "merge" the values of multiple records into a single field without using a stored

  - by j0rd4n

  A co-worker posed this question to me, and I told them, "No, you'll need to write a sproc for that". But I thought I'd give them a chance and put this out to the community. Essentially, they have a table with keys mapping to multiple values. For a report, they want to aggregate on the key and "mash" all of the values into a single field. Here's a visual: --- ------- Key Value --- ------- 1 A 1 B 1 C 2 X 2 Y The result would be as follows: --- ------- Key Value --- ------- 1 A,B,C 2 X,Y They need this in SQLServer 2005. Again, I think they need to write a stored procedure, but if anyone knows a magic out-of-the-box function that does this, I'd be impressed.

• How can I use Code Contracts in a C++/CLI project?

  - by Daniel Wolf

  I recently stumbled upon Code Contracts and have started using them in my C# projects. However, I also have a number of projects written in C++/CLI. For C# and VB, Code Contracts offer a handy configuration panel in the project properties dialog. For a C++/CLI project, there is no such panel. From the documentation, I got the impression that adding Code Contracts support to a C++/CLI project should be a simple matter of calling some external tools as part of the build process (namely ccrefgen.exe, cccheck.exe, and ccrewrite.exe). However, the number of command line options and restrictions concerning the call sequence have me somewhat intimidated. Can anybody point me to a simple way to run the Code Contracts tools as an automated part of the build process in Visual Studio?

• .NET : Targeting the runtime

  - by contactmatt

  I'm starting to read in-depth on the .NET framework, and its Common Language Runtime. I'm reading a .NET overview by Microsoft and I'm not sure what is meant by this statement. Code that targets the runtime is known as managed code, while code that does not target the runtime is known as unmanaged code. How do you target the Common Language Runtime? I know its defaulted when developing in Visual Studio, but how would you specifically target the CLR? What code when developing a .NET application wouldn't target the CLR, and thereby be called unmanaged code?

• WPF: isolated storage file path too long

  - by user342961

  Hi, I'm deploying my WPF app with ClickOnce. When developing locally in Visual Studio, I store files in the isolated storage by calling IsolatedStorageFile.GetUserStoreForDomain(). This works just fine and the generated path is C:\Users\Frederik\AppData\Local\IsolatedStorage\phqduaro.crw\hux3pljr.cnx\StrongName.kkulk3wafjkvclxpwvxmpvslqqwckuh0\Publisher.ui0lr4tpq53mz2v2c0uqx21xze0w22gq\Files\FilerefData\-581750116 (189 chars) But when I deploy my app with ClickOnce, the generated path becomes too long, resulting in a DirectoryNotFoundException when creating the isolated storage directory. The generated path with ClickOnce is: C:\Users\Frederik\AppData\Local\Apps\2.0\Data\OQ0LNXJT.R5V\8539ABHC.ODN\exqu..tion_e07264ceafd7486e_0001.0000_b8f01b38216164a0\Data\StrongName.wy0cojdd3mpvq45404l3gxdklugoanvi\Publisher.ui0lr4tpq53mz2v2c0uqx21xze0w22gq\Files\FilerefData\-581750116 (247 chars) When I browse the folders all but the last directory of the path exists. Then when trying to create a folder at this location windows tells me I can't create a directory because the resulting path name will be too long. How can I shorten the path generated by the IsolatedStorage?

• Ideal dev/test/QA environment for development

  - by Nick

  I am working to rebuild my company's dev/test/QA environment. We have 10-15 programmers that are involved in a number of projects. They currently all develop locally on their PCs and use the dev environment for testing. We currently do not have a QA environment, so deployments are frequently a pain because bugs are usually found after something has gone live. Here's what I envision: Doing away with everyone's local admin privileges and making everyone develop on a dev server Create a QA environment that is identical to our production systems. This will allow them to test deployments. Create a new test environment that is more locked down than the dev server so that proper testing can be done. What are your thoughts? What is the best way to set up an environment like this? We develop ASP .NET applications using MS Visual Studio 2008 (if that helps).

• IEnumerable doesn't have Count

  I have the following method: public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public IEnumerable<RuleViolation> GetRuleViolations(){ //code here } Why is it that when I do .Count above it is underlined in red? I got the following error: Error 1 'System.Collections.Generic.IEnumerable' does not contain a definition for 'Count' and no extension method 'Count' accepting a first argument of type 'System.Collections.Generic.IEnumerable' could be found (are you missing a using directive or an assembly reference?) c:\users\a\documents\visual studio 2010\Projects\NerdDinner\NerdDinner\Models\Dinner.cs 15 47 NerdDinner

• What is a good Visio Enterprise Architect replacement?

  - by MattValerio

  I've been using Visio 2002/2003 Enterprise Architect to do my database schema design visually and then forward-generate the DDL to create the database. I wanted to switch to Visio 2007, but while it does have database diagramming support, it doesn't have the ability to generate DDL. Bummer. I am really disappointed because it seems like Microsoft has completely abandoned this feature. You can't do it in Visual Studio (that I've found). You can sorta do it with SQL Server Management Studio if you insert database diagrams into your database, but any edits to the schema immediately take effect. Has anyone found a good program to do this? I'm hoping to find one that is free and can generate DDL/SQL for SQL Server.

• How to effectively measure developer's work hours?

  - by twk

  I have a few software developers working for my projects and I would like to provide them a way to register time they spent on real development. There is good will to register development hours, no force, but we try to avoid techniques like excel sheets register because this is so uncomfortable. I can track svn commits, but this is unreliable. Developers also helps supporting different projects during the day, so assuming they work on one project by whole day is not true. I've seen utilities that popups a message every hour to confirm the project you're working on but this is annoying. Some kind of active-window-title-anaylzer might help (you can get solution name from there in the case of Visual Studio) but I have no experience with such idea. If you have any experience with programmers/designers work hours registration, please share with me. Thanks

• Creating an installer with WPF forms, packaged files and custom setup actions

  - by RodH257

  I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?

• Why do I randomly get a "error to use section registered as allowDefinition='MachineToApplication'"

  - by Jedidja

  I have seen a few questions on SO about a similar error when deploying a website, but I seem to randomly get this error when building an ASP.NET MVC website in Visual Studio. Performing a clean usually fixes it, but is there any way to avoid this completely? It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. d:...\obj\debug\package\packagetmp\web.config Note that it is complaining about the root web.config, not the one from the Views subdirectory.

• JavaScript Intellisene Problem?

  - by James Wiseman

  I've got an issue with JavaScript intellisense in Visual Web Developer 2008, which I'm starting to believe is "just one of those things", but thought I'd ask here just to check. I have a file MyOtherFile.js with a function GetRandomNumber() defined like so: function GetRandomNumber() { /// <summary> /// Summary description for GetRandomNumber /// </summary> return Math.random(); } When I reference this from another file, screen.js (/// <reference path="MyOtherFile.js" />) I get the intellisense as expected with the summary text as above. If, however, I call the function GetRandomNumber from within its own file (MyOtherFile.js) then I don't get the sumamry description. Any thoughts? Thanks.

• .NET WPF Application : Loading a resourced .XPS document

  - by contactmatt

  I'm trying to load a .xps document into a DocumentViewer object in my WPF application. Everything works fine, except when I try loading a resourced .xps document. I am able to load the .xps document fine when using an absolute path, but when I try loading a resourced document it throws a "DirectoryNotFoundException" Here's an example of my code that loads the document. using System.Windows.Xps.Packaging; private void Window_Loaded(object sender, RoutedEventArgs e) { //Absolute Path works (below) //var xpsDocument = new XpsDocument(@"C:\Users\..\Visual Studio 2008\Projects\MyProject\MyProject\Docs\MyDocument.xps", FileAccess.Read); //Resource Path doesn't work (below) var xpsDocument = new XpsDocument(@"\MyProject;component/Docs/Mydocument.xps", FileAccess.Read); DocumentViewer.Document = xpsDocument.GetFixedDocumentSequence(); } When the DirectoryNotFoundException is thrown, it says "Could not find a part of the path : 'C:\MyProject;component\Docs\MyDocument.xps' It appears that it is trying to grab the .xps document from that path, as if it were an actual path on the computer, and not trying to grab from the .xps that is stored as a resource within the application.

• Jabber .net rostertree error

  - by Farooq

  Hi, Whenever I add the rostertree control to my form, I can see that the PresenceManager and RosterManager property values for it have this error listed: "Unable to cast object of type 'System.Windows.Forms.DataGridViewTextBoxColumn' to type 'System.ComponentModel.Component'." I can compile the solution and all but this error keeps popping up randomly. Can someone advice when this may happen. I'm thinking it has to do with the controls not being added properly. I'm using Visual Studio 2008. Thanks.

• Are there any online database schema drawing tools?

  Hi folks, i wish to draw up some database schemas. Eg, table 1 has zero to many rows in table 2, etc. It's purely for visual purposes (eg. no sql code, etc). Are there any online tools / website that offer this?

I don't want any desktop solutions (because I already have one of these).

• Is it feasible to write a Firefox plugin to make use of ActiveX control on Windows?

  - by Gary B2312321321

  I use an ActiveX control called TAPIEx enabling TAPI phone system integration using MS Access 2000 (+Visual Basic). I want to turn this Access database into a web app with the clients running Firefox (all on internal network). Since Firefox doesnt support ActiveX is it feasible for me to write a Firefox plugin that in turn utilizes the ActiveX control? With regard to how plugins work - Would I be able to call 'functions' of the plugin from page script (eg dial call specifying phone number, check if calls in process)? Would adding these functions to the Firefox right click menu 'globally' inside Firefox be easier? Hope you guys can help. Note I'm not a fulltime programmer; I just need to know how steep the learning curve will be or even if my idea is possible! Ive now found a project to allow using activex controls in firefox that seems to be quite up to date at: http://code.google.com/p/ff-activex-host/

• AjaxControlToolkit 3.0.30930.0 vs System.web.extension

  - by John

  Hi, I recently started to use AjaxControlToolkit v3.0.30930.0 in my application together with System.Web.Extension 3.5. My development environment is Visual Studio 2005, .NET Framework 2.0 and the development language is C#. The Ajax control I used is the ModalPopupExtender. I also used the UpdatePanel and updateprogress controls. Everything is working fine on my development machine. But I got a problem after I deployed the application to a server which does not have System.Web.Extension 3.5 installed, which is understandable. My question is, can the ajax controls I used work without System.Web.Extension 3.5? Say I revert the ajaxcontroltoolkit back to version 1.0.61025.0? I don't have the option to install .NET 3.5 as yet. Thank you for your help. John
