• C#.NET framework 3.5 SP1: satellite assemblies and FullTrust issues when the exe is on the network.

  - by leo

  Hi, I'm executing my .NET app from a network share. Since framework 3.5 SP1, and as explained here: http://blogs.msdn.com/shawnfa/archive/2008/05/12/fulltrust-on-the-localintranet.aspx, the main exe and all the DLLs located in the same folder (but not subfolders) are granted with FullTrust security policy. My problem is that I have subfolders for satellite assemblies with localized strings. Namely, I have: 1) FOLDER\APP.EXE 2) FOLDER\A whole bunch of DLLs 3) FOLDER\LANGUAGE1\Satellite assemblies 4) FOLDER\LANGUAGE2\Satellite assemblies 1 and 2 are automatically granted with FullTrust. 3 and 4 are not and my application is really slow because of that. Is there a way to grant 3 & 4 FullTrust security policy at runtime, since the application running has FullTrust? If not, is there a clean way to have satellite assemblies merged into only one DLL? Thanks a lot.

• Render SSRS .RDL to PDF and just open it.

  - by FelipeFiali

  I tried to be the most descriptive I could. Ok, so since I've never done anything like this before, I guess it's better to ask before starting at all to just don't get the whole process wrong. We have a report that has to be called from an ASP.NET application, it could be a simple button. Through the code-behind, I gotta pass in a paramater, render the report, and don't save it anywhere, just open it to the user, as a .pdf file so he could save or print it. So please, give me links or tips, I'm reading MSDN documentation right now... If you have any suggestion on other technologies, as for the report, I'd like to hear it, but it has to be called from ASP.NET. Thanks in advance!

• Setting winforms ToolStripMenuItem ShortcutKeys to numpad key does not work

  - by Axarydax

  We have the ability to define ShortcutKeys for WinForms application menu items. That way I can tell a menu item File-Save to have a shortcut key Ctrl+S and the menu item's handler is "magically" executed after pressing Ctrl+S. The trouble is with the numeric keypad keys, the ShortcutKey property does not accept them (I don't understand how are they different from the other acceptable keys. MSDN states that the property accepts type System.Windows.Forms.Keys (One of the Keys values. The default is None.); and an InvalidEnumArgumentException would be thrown when the parameter is not one of Keys values. But for example Keys.Divide IS one of Keys values, and yet it can't be used. So how can I set a menu item to have a shortcut for Numpad * or Numpad +? Do I need to handle the key in Form's ProcessCmdKey event? Thanks

• Windows "known folders": is there any one of them which is reliably read/write for all users on all

  - by Stabledog

  SHGetKnownFolderPath() and its cohorts accept one of the constants defined here (http://msdn.microsoft.com/en-us/library/dd378457%28v=VS.85%29.aspx ), returning the path to a directory. I'm looking for one of these folders which is reliably writable by all users (including LocalSystem) on XP, Vista, and Windows 7... but I think I'm striking out. It appears that, in fact, there is no single location on the hard drive anymore where you can put a file and be assured that all users can write to it on all these OS versions, without fiddling the permissions first. Is this true?

• rsRenderingExtensionNotFound error using SSRS 2005

  - by Fermin

  Hi, I am trying to use the Sharp-shooter Silverlight report viewer control. This control has a server side component that renders the reports as XAML for displaying in the client side control. I have tried manually installing the rendering extension, according to the instructions on their website, and also the instructions on MSDN. I have basically copied the dll's into the reporting services bin folder and added the following line to rsreportserver.config file: <Extension Name="XAML" Type="PerpetuumSoft.ReportingService.XamlRendering.XamlRenderer,PerpetuumSoft.ReportingService.XamlRendering"/> I've also added a line into the rssrvpolicy.config file as specified on their site. After I made these changes I went into windows services and restarted the Reporting Services services but I get the following error when I try to run reports: rsRenderingExtensionNotFound: An attempt has been made to use a rendering extension that is not registered for this report server Is there anything else that I need to do to use a custom rendering extension within SSRS 2005?

• How To Create An ASP.NET Designer Host

  - by Zuhaib

  I have been asked to build an application where I can drag and drop few WebControls onto the WebPage designer surface. So far I have read some articles on .NET Framework Design-Time architecture, like, MSDN Article: Hosting WinForms Designers, Developer Function Article etc. But I can't a find a way to host WebForms designer. The only open source implementation that I could find was Mono Develop ASP.NET Visual Designer. But in mono they have used GTK# & Gecko etc to host the designer. I can't find a way to do the same using WinForms. Please suggest me what should I do. Give me some pointers. Should I go ahead and implement it using GTK# and Gecko? PS: My requirement is not very huge. I need just a way to drag and drop simple web controls and save the page.

• Connect to a wireless network programmatically

  - by Josh Adams

  I'm trying to write an application that connects to my company's wireless network automatically on windows XP. I've found the Wireless LAN API but it requires me to have some hotfix installed on the machine, and you need to have sp2 or higher(There are machines with SP1, and I'm required to support any XP machine). I've tried to find some samples about Wireless Zero Configuration on MSDN but with no luck, only samples I've found are for WinCE, I think Microsoft stopped supporting it. In addition I couldn't find where to download the dll and header file for working with the WZC. There must be a way to do it and work on any service pack because I've found Zwlancfg by ENGL

• Configure a Port with an SSL Certificate w\o using Httpcfg

  - by dudia

  Hi, When one develops a self-hosted WCF http server, one of the steps needed is to bind an SSL certificate to a port number: httpcfg set ssl -i 0.0.0.0:8012 -h 0000000000003ed9cd0c315bbb6dc1c08da5e6 as stated in: http://msdn.microsoft.com/en-us/library/ms733791.aspx However, It is hardly expected that in my deployment environment one would be able to do it. (I don't even know if the httpcfg.exe is redistributable) Moreover, if the user changed the port after he installed the product then he will need to run the command again.... how can this step be automated pro grammatically? preferably in C# but if it can only be done in C++ (direct access to the Http Server API) then I will manage :)

• Powerpoint Add-In: Add a Button to PPT to SyntaxHighlight a Textbox

  - by Tigraine

  Hi Guys, I am trying to write an Add-In to Powerpoint that does basically one thing: Give users a Button somewhere to click, once they click on it the currently selected TextField should get syntax highlighted. The Syntax highlighting part is easy, I'm just having a real hard time finding some good information on how to successfully interact with Powerpoint from code. There are some MSDN articles highlighting how to add controls on document start or AddSlide, but no good information on how to extend the UI. Has anyone had some experience in this field and could point me to some resource that may help? Also, I am running Powerpoint 2007 while my customer may end up running PPT2003. How is the backwards compatibility of the Add-ins? greetings Daniel

• ASP.NET MVC Get a list of users with particular profile properties

  - by Sam Huggill

  Hi, I'm using ASP.NET MVC 1 and I have added a custom Profile class using the WebProfile Builder VS add-in (found here: http://code.msdn.microsoft.com/WebProfileBuilder/Release/ProjectReleases.aspx?ReleaseId=980). On one of my forms I want a drop-down list of all users who share a specific profile value in common. I can see that I can get a list of all users using: Membership.GetAllUsers() However I cannot see how to get all users who have a specific profile value, which in my case is CellId. Am I approaching this in the right way? I have used membership roles to define which users are administrators etc, but profiles seems like the right place to group users. Any pointers both in specifics of how to access the user list but also comments on whether am I pursuing the right avenue here would be greatly appreciated. Many thanks, Sam

• PerThreadLifetimeManager in Unity

  - by DorianGrey

  Hi, In the Unity PerThreadLifetimeManager documentation, I read that: "This lifetime manager does not dispose the instances it holds". Ref.: http://msdn.microsoft.com/en-us/library/ff647854.aspx So, if I am using a ThreadPool, does it mean that objects resolved using Unity on a Thread of the ThreadPool will not get disposed at the end of the work done in that thread before being returned to the pool? Any pattern or ideas how I can ensure that the objects do get disposed & I get a clean thread from the thread pool? Thanks!

• registering httpModules in web.config

  - by Praesagus

  I am trying to register a custom HttpHandler in the web.config file. MSDN's example shows an entry that is commented out...um which doesn't work so well. When I uncomment I receive a Could not load file or assembly 'HttpModule.cs' or one of its dependencies. The system cannot find the file specified. error. The file name is HttpModule.cs and the class name is MyHttpModule. There is no explicit namespace yet. <httpModules> <add name="MyHttpModule" type="MyHttpModule, HttpModule" /> <httpModules> I am sure I am overlooking the obvious. Do I need to specify the file path somewhere? Thanks in advance.

• How to unit test C# Web Service with Visual Studio 2008

  - by Steven Behnke

  How are you supposed to unit test a web service in C# with Visual Studio 2008? When I generate a unit test it adds an actual reference to the web service class instead of a web reference. It sets the attributes specified in: http://msdn.microsoft.com/en-us/library/ms243399(VS.80).aspx#TestingWebServiceLocally Yet, it will complete without executing the test. I attempted to add the call to WebServiceHelper.TryUrlRedirection(...) but the call does not like the target since it inherits from WebService not WebClientProtocol. Thanks, Steven

• Expression Studio 4 Premium & SketchFlow: Am I screwed?

  - by Refracted Paladin

  Through work I have an Visual Studio Premium with MSDN subscription that I love. However, my biggest disappointment of the last 12 months was discovering that our 2nd from the top level subscription was not enough to get me Sketchflow! This sucks and I am borderline distraught! What are my options? Upgrading to an Ultimate subscription for Sketchflow is out of the question. Am I forced, then, to stay with Blend 3 or Purchase Blend 4 seperately? If this is not a question I should ask here please inform and I'll delete. I just tend to default to SO for all questions that Google can't answer and Google did not answer this one.

• Office ribbon for WPF 4.0

  - by Arcturus

  Hi all, It is rumoured that WPF 4.0 would deliver us an out-of-the-box Office Ribbon. A new WPF Ribbon Control will be available for download shortly after the release of WPF 4. [1] Now my internet and MSDN search turned out to be fruitless, and as far as I know, it would be release after the .NET 4.0 framework would launch. My search lead me to the Office plugin ribbon controls and the CTP prereleased before the release of .net 4.0 with a limited featureset. So my question is: does anyone know if and when Microsoft will release this Office Ribbon with the framework? Or if they don't a nice press note saying that they ditched the project. Also if anyone has experience with the Ribbon I'm talking about, will this Ribbon work in a partial trusted environment? My thanks will be ever lasting! ;)

• SQL Server Full-Text Search: Hung processes with MSSEARCH wait type

  - by CheeseInPosition

  We have a SQL Server 2005 SP2 machine running a large number of databases, all of which contain full-text catalogs. Whenever we try to drop one of these databases or rebuild a full-text index, the drop or rebuild process hangs indefinitely with a MSSEARCH wait type. The process can’t be killed, and a server reboot is required to get things running again. Based on a Microsoft forums post[1], it appears that the problem might be an improperly removed full-text catalog. Can anyone recommend a way to determine which catalog is causing the problem, without having to remove all of them? [1] [http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2681739&SiteID=1] “Yes we did have full text catalogues in the database, but since I had disabled full text search for the database, and disabled msftesql, I didn't suspect them. I got however an article from Microsoft support, showing me how I could test for catalogues not properly removed. So I discovered that there still existed an old catalogue, which I ,after and only after re-enabling full text search, were able to delete, since then my backup has worked”

• Schema compare with MS Data Tools in VS2008

  - by rdkleine

  When performing a schema compare having db_owner rights on the target database results in the following error: The user does not have permission to perform this action. Using the SQL Server Profiler I figured out this error occurs executing a query targeting the master db view: [sys].[dm_database_encryption_keys] While specifically ignoring all object types but Tables one would presume the SQL Compare doesn't need access to the db encryption keys. Also note: http://social.msdn.microsoft.com/Forums/en-US/vstsdb/thread/c11a5f8a-b9cc-454f-ba77-e1c69141d64b/ One solution would be to GRANT VIEW SERVER STATE to the db user, but in my case I'm not hosting the database services and won't get the rights to the server state. Also tried excluding DatabaseEncryptionKey element in the compare file. <PropertyElementName> <Name>Microsoft.Data.Schema.Sql.SchemaModel.SqlServer.ISql100DatabaseEncryptionKey</Name> <Value>ExcludedType</Value> </PropertyElementName> Anyone has an workaround this?

• Any software transforming broken lines into curves?

  - by brilliant

  Hello, do you know of any software that would help me transform a broken line into a curved line? For example, I have an octagon or a heptagon and I want it to be transformed into something resembling a circle. if you know such software, please, let me know. Thank You! Update A: Here is an image from the tutorial given to me by Jamie Keeling (right now it's the first answer below). At least the picture there represents what I want. In that tutorial this process is called "flattening paths". I will try to put that image right here, but if it doesn't get displayed, you can find it here: http://msdn.microsoft.com/en-us/library/ms536364%28v=VS.85%29.aspx The red line in the picture is what I would want to submit, and the blue line is what I would want to get in the end:

• Moving from WCF RIA Beta to RC: best practices?

  - by Duncan Bayne

  I have an existing WCF RIA project built on the Release Candidate; I'm now moving to the Release version & have discovered many changes. David Scruggs made the following comment on his (MSDN) blog: "If you’ve written anything in SIlverlight 4 RIA Services, you’ll need to rewrite it. There has been a lot of refactoring and namespace moves." Having made a brief attempt to compile the old solution with the new RIA framework I'm inclined to agree. My current plan is to: remove the Silverlight Business Application projects from the Solution rebuild the EF4 items from the database create a new Silverlight Business Application project re-add the files (XAML, CS) from the old Silverlight Business Application project Does this sound like a reasonable approach? I think it's cleaner than trying to manually alter the existing project.

• WPF slow to start on x64 in .NET Framework 4.0

  - by Robert Fraser

  I've noticed that if I build my WPF application for Any CPU/x64, it takes MUCH longer to start (on the order of about 20 seconds) or to load new controls than it does if started on x86 (in release & debug modes, inside or outside of VS). This occurs with even the simplest WPF apps. The problem is discussed in this MSDN thread, but no answer was provided there. This happens only with .NET 4.0 -- in 3.5 SP1, x64 was just as fast as x86. Interestingly, Microsoft seems to know about this problem since the default for a new WPF project in VS2010 is x86. Is this a real bug or am I just doing it wrong? EDIT: Possibly related to this: http://stackoverflow.com/questions/2788215/slow-databinding-setup-time-in-c-net-4-0. I'm using data binding heavily.

• WCF, net.tcp, and ASP.NET development server

  - by bryanjonker

  I'm setting up a net.tcp WCF service using instructions here: http://blogs.msdn.com/swiss_dpe_team/archive/2008/02/08/iis-7-support-for-non-http-protocols.aspx One of the steps says to do the following: "If you open the IIS7 management console and you look at the advance setting of our IIS7HostedService Web Application, you will see that in the Enabled Protocols section just http is defined. You now have to add net.tcp (separated by a comma), so that our service will be able to respond also to TCP requests." This is fine, but what if I want to use the Cassini / VS2010 ASP.NET development server to debug (hitting F5 or cntrl-F5)? I don't think there's a way to change the settings in that IIS. Or is there? Are other programmers just so awesome that they don't need to go through the debugger? Or do they use wsHttpBinding?

• SQL - .NET - SqlParameters - AddWithValue - Are there any negative performance implications when Par

  - by hamlin11

  http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlparametercollection.addwithvalue.aspx I'm used to adding sql parameters to a sqlCommand using the add() function. This allows me to specify the type of the sqlParameter, but it requires another line to set the value. It's nice to use the AddWithValue function, but it skips the "specify the parameter type" step. I'm guessing this causes the parameters to be sent over as strings contained within single quotes (''), but I'm not sure. Is this the case, and does this cause significantly slower performance of the stored procedures? Note: I understand that it is nice to validate user data on the .NET side of things by specifying the data type for params -- I'm only concerned about reflection-type overhead of AddWithValue either on the .NET or SQL side.

• How to read time phased data from Project Server 2007 directly from Project Server Database ?

  - by Nikhil Vaghela

  I am working on a custom web part for Project Web Access, for Project Server 2007. We are so far using PSI web services only to read and write data from and to Project Server 2007 databases. But there is a signinficant performance issue when you retrieve time phased data through Statusing web service, it is basically an expensive call for querying time phased data for each tasks. I want to access Time phased data entered by user for each tasks by directly hitting the Project Server Database. [ I do not want the solution suggested at this link : http://blogs.msdn.com/project_programmability/archive/2007/05/24/getting-at-the-task-time-phased-data.aspx as it reads data from reporting database which gets entry only after the project is published. ] I want to get time phased data as soon as user enters it. Any idea ? Thanks.

• Flash swf to play PCM WAV files?

  - by Geuis

  I am in need of a Flash swf that is capable of loading PCM WAV files via a url passed to it. An example of the file can be found here: http://msdn.microsoft.com/en-us/library/ff512405.aspx The swf does not need a visible interface, as it is meant for audio playing only and not user interaction. The swf should have a simple javascript interface for page-level interactions. These include: load(url): loads a PCM WAV file over the internet using the url that is passed through it. play(): Should play the PCM WAV file that was loaded stop(): Should stop playing the current file. I can provide a sample audio file that matches the specifications if the developer is unable to obtain a url from the link posted above.

• Debugging ASP.NET Strings Downloaded to Browser (Montréal instead of Montréal)

  - by jdk

  I'm downloading a vCard to the browser using Response.Write to output .NET strings with special accented characters. Mime type is text/x-vcard and French characters are appearing wrong in Outlook, for example Montréal;Québec .NET string shows as Montréal Québec in browser. I'm using this vCard generator code from CodeProject.com I've played with the System.Encoding sample code at the bottom of this linked MSDN page to convert the unicode string into bytes and then write the ascii bytes but then I get Montr?al Qu?bec (progress but not a win). Also I've tried setting content type to both us-ascii and utf-8 of the response. If I open the downloaded vCard in Windows Notepad and save it as ANSI text (instead of default unicode format) and open in Outlook it's okay. So my assumption is I need to cause download of ANSI charset but am unsure if I'm doing it wrong or have a misunderstanding of where to start. Update: Looking at the raw HTTP, it appears my French characters are being downloaded in the unexpected format so it looks like I need to do some work on the server side... (full size)
