  • Visual Studio 2010 crashes nearly every time when closing

    - by Andrei Drynov
    Mostly it happens if we open a team project from tfs 2008 or tfs 2010, but crashes can happen any time. When VS is closing down, it crashes nearly every time. Tried trial RTM and our MSDN download - same story. Tried on three different PCs - same issue. Tried on 32 and 64-bit Windows 7 and Windows Server 2008 R2 - crashes. Is it just our luck or does it happen to you to?

  • FILESTREAM/FILETABLE Clarifications for Implementation

    - by user1209734
    Recently our team was looking at FILESTREAM to expand the capabilities of our proprietary application. The main purpose of this app is managing the various PDFS, Images and documents to all of the parts we manufacture. Our ASP application uses a few third party tools to allow viewing of these files. We currently have 980GB of data on the Fileserver. We have around 200GB of Binary data in SQL Server that we would like to extract since it is not performing well hence FILESTREAM seems to be a good compromise to the two major data storage/access issues. A few things are not exactly clear to us: FILESTREAM Can or Cannot store its data on a drive that is not locally attached. We already have a File Server with a RAID 10 (1.5TB drives). This server stores all of the documents right now, would we have to move these drives to the SQL Server for FILESTREAM? That would be a tough bullet to bite since the server also is doubling as the Application Server (Two VMs on one physical server). FILETABLE stores the common metadata about the files but where is the Full Text part of it stored to allow searching of files like doc/docx? Is this separate? Are you able to freely add criteria to this to search by? If so any links to clarify would be appreciated. Can FILETABLE be referenced in another table with a foreign key? Thank you in advance EDIT: For those having these questions this web video covered everything and more in terms of explaining filestream from 2008 to 2012 and the cavets to consider (I would seriously rep him if I could): http://channel9.msdn.com/Events/TechDays/Techdays-2012-the-Netherlands/2270 In conclusion we will not be using FILESTREAM as it would be way to huge of an upsurge to accommodate for investment. EDIT 2: Update to #1 - After carefully assessing FileTable in addition to FILESTREAM we got a winning combination. We did have to move the files over to the new server (wasn't to painful since they were on the same VM).It honestly took more time to write an extraction tool to dump the binary data within SQL to the File System. Update to #2 - This was seperate but again Bob had an excellent webinar explaining this: http://channel9.msdn.com/Events/TechEd/Europe/2012/DBI411 Update to #3 - Using TFT inheritance we recycled the Docs table we had (minus the huge binary blobs) which required very little changes in our legacy apps. This was a huge upshot for the developer team.

  • Ajax call to wcf windows service over ssl (https)

    - by bpatrick100
    I have a windows service which exposes an endpoint over http. Again this is a windows service (not a web service hosted in iis). I then call methods from this endpoint, using javascript/ajax. Everything works perfectly, and this the code I'm using in my windows service to create the endpoint: //Create host object WebServiceHost webServiceHost = new WebServiceHost(svcHost.obj, new Uri("http://192.168.0.100:1213")); //Add Https Endpoint WebHttpBinding binding = new WebHttpBinding(); webServiceHost.AddServiceEndpoint(svcHost.serviceContract, binding, string.Empty); //Add MEX Behaivor and EndPoint ServiceMetadataBehavior metadataBehavior = new ServiceMetadataBehavior(); metadataBehavior.HttpGetEnabled = true; webServiceHost.Description.Behaviors.Add(metadataBehavior); webServiceHost.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName, MetadataExchangeBindings.CreateMexHttpBinding(), "mex"); webServiceHost.Open(); Now, my goal is to get this same model working over SSL (https not http). So, I have followed the guidance of several msdn pages, like the following: http://msdn.microsoft.com/en-us/library/ms733791(VS.100).aspx I have used makecert.exe to create a test cert called "bpCertTest". I have then used netsh.exe to configure my port (1213) with the test cert I created, all with no problem. Then, I've modified the endpoint code in my windows service to be able to work over https as follows: //Create host object WebServiceHost webServiceHost = new WebServiceHost(svcHost.obj, new Uri("https://192.168.0.100:1213")); //Add Https Endpoint WebHttpBinding binding = new WebHttpBinding(); binding.Security.Mode = WebHttpSecurityMode.Transport; binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate; webServiceHost.AddServiceEndpoint(svcHost.serviceContract, binding, string.Empty); webServiceHost.Credentials.ServiceCertificate.SetCertificate("CN=bpCertTest", StoreLocation.LocalMachine, StoreName.My); //Add MEX Behaivor and EndPoint ServiceMetadataBehavior metadataBehavior = new ServiceMetadataBehavior(); metadataBehavior.HttpsGetEnabled = true; webServiceHost.Description.Behaviors.Add(metadataBehavior); webServiceHost.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName, MetadataExchangeBindings.CreateMexHttpsBinding(), "mex"); webServiceHost.Open(); The service creates the endpoint successfully, recognizes my cert in the SetCertificate() call, and the service starts up and running with success. Now, the problem is my javascript/ajax call cannot communicate with the service over https. I simply get some generic commication error (12031). So, as a test, I changed the port I was calling in the javascript to some other random port, and I get the same error - which tells me that I'm obviously not even reaching my service over https. I'm at a complete loss at this point, I feel like everything is in place, and I just can't see what the problem is. If anyone has experience in this scenario, please provide your insight and/or solution! Thanks!

  • How does CommandManager.RequerySuggested work?

    - by Andrei Rinea
    The MSDN only states that Occurs when the CommandManager detects conditions that might change the ability of a command to execute. However I can't seem to find any traces of how this works, what I should be aware of / avoid etc... Does it just listen for input? (i.e.: mouse moves, keys pressed and so on)

    I;m trying to get WCF Silverlight faults working as per this : MSDN aricle After adding the SL fault to my Web.config file I get the following warning: The element 'behavior' has invalid child element 'silverlightFaults'. List of possible elements expected: 'serviceAuthorization, serviceCredentials, serviceMetadata, serviceSecurityAudit, serviceThrottling, dataContractSerializer, serviceDebug, serviceTimeouts, persistenceProvider, workflowRuntime'. Ignoring the warning doesn't work and my Silverlight application cannot add the WCF service. Any ideas?

  • Async BinaryWriter ?

    - by blez
    I found implementation of async BinaryWriter here: http://social.msdn.microsoft.com/Forums/en-US/netfxbcl/thread/11f6aa76-1383-4cab-8693-29dcb25bbf2e But I can't really use it. I change all my types to AsyncBinaryWriter and I use .Write, but no data is written to the stream. Is that the proper way for using it ?

  • ie8 breaks with asp.net ajax

    - by Amadeo Torese
    Hello, When using asp.net ajax (scriptmanager, timer, updatepanel) with ie8, after certain time (~3h) IE breaks with null object, constructor, or paramArray (depending on the asp.net code). Even with the simplest timer (no ajax, no updatepanel) ie8 still breaks. On every other browser it works fine, and if I code the ajax myself it works. Since google and msdn forums turned up nothing I'm wondering if anybody here has had similar problems with ie8 browser.

  • availability of Win32_MountPoint and Win32_Volume on Windows XP?

    - by SteveC
    From the MSDN articles I've found -- http://msdn.microsoft.com/en-us/library/aa394515(v=VS.85).aspx -- Win32_Volume and Win32_MountPoint aren't available on Windows XP. However, I'm developing a C# app on Windows XP (64bit), and I can get to those WMI classes just fine. Users of my app will be on Windows XP sp2 with .Net 3.5 sp1. Googling around, I can't determine whether I can count on this or not. Am I successful on my system because of one or more of the following: - windows xp service pack 2? - visual studio 2008 sp1 was installed? - .Net 3.5 sp1? Should I use something other than WMI to get at the volume/mountpoint info? Below is sample code that's working... public static Dictionary<string, NameValueCollection> GetAllVolumeDeviceIDs() { Dictionary<string, NameValueCollection> ret = new Dictionary<string, NameValueCollection>(); // retrieve information from Win32_Volume try { using (ManagementClass volClass = new ManagementClass("Win32_Volume")) { using (ManagementObjectCollection mocVols = volClass.GetInstances()) { // iterate over every volume foreach (ManagementObject moVol in mocVols) { // get the volume's device ID (will be key into our dictionary) string devId = moVol.GetPropertyValue("DeviceID").ToString(); ret.Add(devId, new NameValueCollection()); //Console.WriteLine("Vol: {0}", devId); // for each non-null property on the Volume, add it to our NameValueCollection foreach (PropertyData p in moVol.Properties) { if (p.Value == null) continue; ret[devId].Add(p.Name, p.Value.ToString()); //Console.WriteLine("\t{0}: {1}", p.Name, p.Value); } // find the mountpoints of this volume using (ManagementObjectCollection mocMPs = moVol.GetRelationships("Win32_MountPoint")) { foreach (ManagementObject moMP in mocMPs) { // only care about adding directory // Directory prop will be something like "Win32_Directory.Name=\"C:\\\\\"" string dir = moMP["Directory"].ToString(); // find opening/closing quotes in order to get the substring we want int first = dir.IndexOf('"') + 1; int last = dir.LastIndexOf('"'); string dirSubstr = dir.Substring(first , last - first); // use GetFullPath to normalize/unescape any extra backslashes string fullpath = Path.GetFullPath(dirSubstr); ret[devId].Add(MOUNTPOINT_DIRS_KEY, fullpath); } } } } } } catch (Exception ex) { Console.WriteLine("Problem retrieving Volume information from WMI. {0} - \n{1}",ex.Message,ex.StackTrace); return ret; } return ret; }

  • What’s the status of CAT.NET?

    - by Troy Hunt
    I’m trying to find Microsoft CAT.NET for VS2010 and it looks like there was a beta of their 2.0 version but every link to it in Microsoft Connect is now dead. This is the most recent reference I could find: http://blogs.msdn.com/securitytools/archive/2010/02/05/how-to-use-cat-net-2-0-beta.aspx Some references suggest it may have been rolled into FxCop. Does anyone know the status of the project?

  • Register applications via Registry table rather than TLBs

    - by Mmarquee
    We register the capabilities of Delphi applications using TLB files. However, from reading MSDN documentation, "Installation package authors are strongly advised against using the TypeLib table. Instead, they should register type libraries by using the Registry table". Does anyone have any advice on how to do this in a 'Delphi' way for Windows 7?

  • Where is cmcfg32.lib?

    - by Doo Dee
    Hello! I found a source code on MSDN about how to enable/disable privileges in C++ According to the source code, the linker must include cmcfg32.lib, but it can't be found... I tried to compile without including that lib, it compiles without any error, but when I launch my program, it crashes with a fatal error. So please, if you know which SDK contains cmcfg32.lib, let me know ;) Thanks!

  • Asp.NET MVC Areas

    - by RailRhoad
    So we finally got "areas" in our ASP.NET MVC framework! I'm able to get them up and going but one thing that bothers me is the amount of development servers it instantiates! So I currently have 6 areas, and when I run it I get 6 dev server instances running. Is this really necessary? MSDN is having me setup these areas as seperate web apps, couldn't we get these down into class libraries somehow?

  • General advice and guidelines on how to properly override object.GetHashCode()

    - by Svish
    According to MSDN, a hash function must have the following properties: If two objects compare as equal, the GetHashCode method for each object must return the same value. However, if two objects do not compare as equal, the GetHashCode methods for the two object do not have to return different values. The GetHashCode method for an object must consistently return the same hash code as long as there is no modification to the object state that determines the return value of the object's Equals method. Note that this is true only for the current execution of an application, and that a different hash code can be returned if the application is run again. For the best performance, a hash function must generate a random distribution for all input. I keep finding myself in the following scenario: I have created a class, implemented IEquatable<T> and overridden object.Equals(object). MSDN states that: Types that override Equals must also override GetHashCode ; otherwise, Hashtable might not work correctly. And then it usually stops up a bit for me. Because, how do you properly override object.GetHashCode()? Never really know where to start, and it seems to be a lot of pitfalls. Here at StackOverflow, there are quite a few questions related to GetHashCode overriding, but most of them seems to be on quite particular cases and specific issues. So, therefore I would like to get a good compilation here. An overview with general advice and guidelines. What to do, what not to do, common pitfalls, where to start, etc. I would like it to be especially directed at C#, but I would think it will work kind of the same way for other .NET languages as well(?). I think maybe the best way is to create one answer per topic with a quick and short answer first (close to one-liner if at all possible), then maybe some more information and end with related questions, discussions, blog posts, etc., if there are any. I can then create one post as the accepted answer (to get it on top) with just a "table of contents". Try to keep it short and concise. And don't just link to other questions and blog posts. Try to take the essence of them and then rather link to source (especially since the source could disappear. Also, please try to edit and improve answers instead of created lots of very similar ones. I am not a very good technical writer, but I will at least try to format answers so they look alike, create the table of contents, etc. I will also try to search up some of the related questions here at SO that answers parts of these and maybe pull out the essence of the ones I can manage. But since I am not very stable on this topic, I will try to stay away for the most part :p

  • Dealing with security on IPC remoting channel

    - by leppie
    Hi I am trying to run a service under a different user account from the application that will access the service via remoting. While under the same account everything is fine, but as soon as I use different accounts, I get an access denied error while trying to open the IPC port. Is there something I am missing, as I can't see from the MSDN docs what is supposed to be done. Thanks

  • Function to Calculate Median in Sql Server

    - by Yaakov Ellis
    According to MSDN, Median is not available as an aggregate function in Transact-Sql. However, I would like to find out whether it is possible to create this functionality (using the Create Aggregate function, user defined function, or some other method). What would be the best way (if possible) to do this - allow for the calculation of a median value (assuming a numeric data type) in an aggregate query?

  • WPF ListView groups repeat column headers

    - by Riko
    Is there a way to repeat the column headers inside each group of a ListView.GridView when using a grouped CollectionViewSource as the source of the ListView? I am using the example at http://msdn.microsoft.com/en-us/library/ms754027.aspx which uses an Expander control to display each group. I would like the column headers to appear inside the expander for each group instead of at the top of the ListView.

  • Problem: adding feature in MOSS 2007

    - by Anoop
    Hi All, I have added a menu item in 'Actions' menu of a document library as follows(Using features: explained in MSDN How to: Add Actions to the User Interface: http://msdn.microsoft.com/en-us/library/ms473643.aspx): feature.xml as follows: <?xml version="1.0" encoding="utf-8" ?> <Feature Id="51DEF381-F853-4991-B8DC-EBFB485BACDA" Title="Import From REP" Description="This example shows how you can customize various areas inside Windows SharePoint Services." Version="1.0.0.0" Scope="Site" xmlns="http://schemas.microsoft.com/sharepoint/"> <ElementManifests> <ElementManifest Location="ImportFromREP.xml" /> </ElementManifests> </Feature> ImportFromREP.xml is as follows: <?xml version="1.0" encoding="utf-8"?> <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <!-- Document Library Toolbar Actions Menu Dropdown --> <CustomAction Id="ImportFromREP" RegistrationType="List" RegistrationId = "101" GroupId="ActionsMenu" Rights="AddListItems" Location="Microsoft.SharePoint.StandardMenu" Sequence="1000" Title="Import From REP"> <UrlAction Url="/_layouts/ImportFromREP.aspx?ActionsMenu"/> </CustomAction> </Elements> I have successfully installed and activated the feature. Normal case: Now if i login with the user having atleast 'Contribute' permission on the document library, i am able to see the menu item 'Import From REP' (in 'Actions' menu)in root folder as well as in all subfolders. Problem case: If user is having view rights on the document library but add/delete rights on a perticular subfolder(say 'subfolder') inside the document library: Menu item 'Import From REP' is not visible on root folder level as well as 'Upload' menu is also not visible. which is o.k. because user does not have AddListItems right on root folder but it is also not visible in 'subfolder' while 'Upload' menu is visible as user has add/delete rights on the 'subfolder'. did i mention a wrong value of attribute Rights(Rights="AddListItems") in the xml file?? If so, what should be the correct value? What should i do to simulate the behaviour of 'Upload' menu??(i.e. when 'Upload' menu is visible, 'Import From REP' menu is visible and when 'Upload' menu is not visible 'Import From REP' menu is also not visible. ) Thanks in advance Anoop

  • CodePage ID to CodePage name: GetEncoding equivalent in Delphi?

    - by Steve
    Hello all, I'm looking for a Win32 equivalent of the .Net Encoding.GetEncoding Method to be used in Delphi7. What I would like to achieve is to convert a Codepage ID (ie.: 28592) to a Codepage name (iso-8859-2 in this case). I've found a Win32 function called GetCPInfoEx, but that returns a long CodePage name, and I need the short one, like the ones listed on this page: (see Name column) http://msdn.microsoft.com/en-us/library/system.text.encoding.aspx Thank you!
