  • How can I attach a Silverlight OOB to a Winforms panel?

    - by JohnMcCon
    Summary: I want the prettiness of Silverlight/WPF in part of my current Winforms application. The application can only have access to the full .NET Framework 2.0, no more and no less. The only possibility I can think of is a Silverlight OOB application that utilizes Com+ Automation but I can't figure out how to attach the Silverlight application to a panel within the parent Winforms application. Details: I currently have a winforms application, and want to take advantage of the improved GUI features in WPF but to many of my users are still running .Net Framework 2.0 and refuse to update to 3+. So WPF is not an option for me. I know Silverlight is just a subset of WPF, but it has most of the features I'm looking for and only requires the Silverlight plug-in. I've read about Silverlight 4's Com+ Automation, which would give me access to the full desktop .Net Framework 2.0 (which I need). In order for Com+ Automation to work in Silverlight I need elevated trust and the only way I can find to gain elevated trust is to make my Silverlight application Out-Of-Browser (OOB). My problem is that the OOB application seems to run in its own container window and I need the Silverlight application embedded inside a panel in my Winforms application. My Winforms application does not need to communicate with the Silverlight application and vice-versa, this is purely to have everything contained and displayed in one window. If there is another way to get my desired result that I have not thought of feel free to suggest it.

  • What is the reason of "Transaction context in use by another session"

    - by Shrike
    Hi, I'm looking for a description of the root of this error: "Transaction context in use by another session". I get it sometimes in one of my unittests so I can't provider repro code. But I wonder what is "by design" reason for the error. I've found this post: http://blogs.msdn.com/asiatech/archive/2009/08/10/system-transaction-may-fail-in-multiple-thread-environment.aspx and also that: http://msdn.microsoft.com/en-us/library/ff649002.aspx But I can't understand what "Multiple threads sharing the same transaction in a transaction scope will cause the following exception: 'Transaction context in use by another session.' " means. All words are understandable but not the point. I actually can share a system transaction between threads. And there is even special mechanism for this - DependentTransaction class and Transaction.DependentClone method. I'm trying to reproduce a usecase from the first post: 1. Main thread creates DTC transaction, receives DependentTransaction (created using Transaction.Current.DependentClone on the main thread 2. Child thread 1 enlists in this DTC transaction by creating a transaction scope based on the dependent transaction (passed via constructor) 3. Child thread 1 opens a connection 4. Child thread 2 enlists in DTC transaction by creating a transaction scope based on the dependent transaction (passed via constructor) 5. Child thread 2 opens a connection with such code: using System; using System.Threading; using System.Transactions; using System.Data; using System.Data.SqlClient; public class Program { private static string ConnectionString = "Initial Catalog=DB;Data Source=.;User ID=user;PWD=pwd;"; public static void Main() { int MAX = 100; for(int i =0; i< MAX;i++) { using(var ctx = new TransactionScope()) { var tx = Transaction.Current; // make the transaction distributed using (SqlConnection con1 = new SqlConnection(ConnectionString)) using (SqlConnection con2 = new SqlConnection(ConnectionString)) { con1.Open(); con2.Open(); } showSysTranStatus(); DependentTransaction dtx = Transaction.Current.DependentClone(DependentCloneOption.BlockCommitUntilComplete); Thread t1 = new Thread(o => workCallback(dtx)); Thread t2 = new Thread(o => workCallback(dtx)); t1.Start(); t2.Start(); t1.Join(); t2.Join(); ctx.Complete(); } trace("root transaction completes"); } } private static void workCallback(DependentTransaction dtx) { using(var txScope1 = new TransactionScope(dtx)) { using (SqlConnection con2 = new SqlConnection(ConnectionString)) { con2.Open(); trace("connection opened"); showDbTranStatus(con2); } txScope1.Complete(); } trace("dependant tran completes"); } private static void trace(string msg) { Console.WriteLine(Thread.CurrentThread.ManagedThreadId + " : " + msg); } private static void showSysTranStatus() { string msg; if (Transaction.Current != null) msg = Transaction.Current.TransactionInformation.DistributedIdentifier.ToString(); else msg = "no sys tran"; trace( msg ); } private static void showDbTranStatus(SqlConnection con) { var cmd = con.CreateCommand(); cmd.CommandText = "SELECT 1"; var c = cmd.ExecuteScalar(); trace("@@TRANCOUNT = " + c); } } It fails on Complete's call of root TransactionScope. But error is different: Unhandled Exception: System.Transactions.TransactionInDoubtException: The transaction is in doubt. --- pired. The timeout period elapsed prior to completion of the operation or the server is not responding. To sum up: I want to understand what "Transaction context in use by another session" means and how to reproduce it.

  • HttpUtility does not exist in the current context

    - by Shaihi
    I get this error when compiling a C# application. Looks like a trivial error, but I can't get around it. My setup is Windows 7 64 bit. Visual-Studio 2010 C# express B2Rel. I added a reference to System.Web.dll located at C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0, but it has a yellow exclamation symbol and I still get the above error. I also have the using System.Web declaration. What am I doing wrong? Update: After getting the prompt answer pointing me at the root cause, I searched a bit in Google to where it states that System.Web.dll is for the full framework. I did not find such a reference. For newbies like me, this blog summarizes the difference between the frameworks (client and full) nicely. I could not find a spot that says whether a certain Dll is supported in the client framework or not. I guess the exclamation mark in Visual Studio should be the first signal...

  • Custom Installer class , rollback method never called.

    - by yossi1981
    Hi guys. I am having an installer class , Here is a snippet: [RunInstaller(true)] public partial class ServerWrapInstaller : Installer { public override void Install(IDictionary stateSaver) { EventLog.WriteEntry("Installer", "Install", EventLogEntryType.Information); base.Install(stateSaver); } public override void Commit(IDictionary savedState) { EventLog.WriteEntry("Installer", "Commit", EventLogEntryType.Information); base.Commit(savedState); } public override void Rollback(IDictionary savedState) { EventLog.WriteEntry("Installer", "Rollback", EventLogEntryType.Information); base.Rollback(savedState); } public override void Uninstall(IDictionary savedState) { EventLog.WriteEntry("Installer", "UnInstall", EventLogEntryType.Information); base.Uninstall(savedState); } } Now i start the installation in full GUI mode and then click the "Cancel" button in the middle of the process causing the installation to roll back. The problem is that the RollBack method is not called. I don't see the expected entry in the event log. I want to mention that if i let the installation to complete , I do see the "Install" message in the event log and If i then uninstall , I see the "uninstall" message in the event log. But if stop the installtion process in the middle , by pressing the "cancel" button , I do see the progress bar going backward , but the rollback method is not called. what am I doing wrong ? thanks in advance for any help. Edit: Providing more details... The installer is an MSI package. The package is built in vs2009 using a setup project. The installer class is used as a custom action by the setup project. Since this is a MSI Package I have an option to run it in silent mode or in user-interactive more . When I wrote "Full GUI mode" , I ment User-Interactive mode.

  • Unable to authenticate Windows XP clients agains Snow Leopard Server PDC after 10.6.2 upgrade

    - by Roland
    I have setup a Snow Leopard Server 10.6.1 as a PDC without problems to authenticate Windows XP clients. Joining a Windows XP client to the SLS PDC Domain and log in from a Windows XP client to the SLS PDC Domain are working. After the update to Snow Leopard Server 10.6.2 the authentication is broken. opendirectory_smb_pwd_check_ntlmv1 gave -14090 [eDSAuthFailed] By changing the Windows XP "Network security: LAN Manager authentication level" policy to NTVLM2 responses only the authentication agains a SMB share is possible, but trying to join SLS PDC Domain is still not possible. opendirectory_smb_pwd_check_ntlmv2 gave -14090 [eDSAuthFailed] Any ideas? Is anyone else having similar authentication difficulties?

  • Problems with mailenable when sending to yahoo mail

    - by Mee
    I'm testing sending emails from mailenable webmail. I have no problems sending mail to gmail or hotmail, both work fine, but yahoo mail sends my messages to the spam folder and shows the attachment icon for the message even though the message doesn't contain any attachments, it's just plain text. It only includes a reply to a previous message, like this: message text ----- Original Message ----- original message text I copied the message content and sent it from gmail to yahoo and the attachment icon didn't show which makes me believe it's something with mailenable. What could possibly be wrong? Also, is there a white list for yahoo mail that I can join? And also for other popular webmail? I'm going to use this on a production website (site visitors use the contact us form to send messages to the site - the mail enable server running on the same machine as the web server - then I check the messages using the mailenable webmail and reply them). This is really important to me, your help would be really appreciated ...

  • Add server 2008 to 2003 domain schema upgrade failed

    - by Ken
    I'm trying to add a server 2008 r2 server to an existing 2003 domain (upgraded to 2003 functionality). I've followed the steps from microsoft which are clarified by this post: 2003 DC AD upgrade to 2008 on second server migration plan While running adprep /forestprep I lost my connection and wasn't able to resume or remote control that session, so I couldn't see the end result of the command. Rerunning adprep /forestprep indicates that the process has already been completed successfully. After finishing the rest of the steps (/domainprep ... and /gpprep, etc), the 2008 server won't join. The error message is the same "you need to run forestprep first" So the situation I'm in is that I can't rerun /forestprep, but my Registry key still reads schemaVer=30. Should I have staged forest upgrades? Any ideas how to get my schema ver to 44 at this point?

  • Ruby rail debug output

    - by Darkerstar
    Hi all: I am just starting to write ruby rails. I wrote a controller but is getting wrong number of "arguments (1 for 0)" error, I can't understand why. It has no information on where the error occurred? It has a full list of stack traces but my controller file is not in there! In my controller I have just two methods, that I was going to test out activemq. But after I put the controller out, I got the above error, so I commented out all the code, but I still get the same error. I can't figure out why.

  • Setting up kerberos for SQL Server 2008 R2 not taking effect

    - by dotnetdev
    I am trying to configure Kerberos for my SQL Server (the database engine domain account). I have executed the following command: SETSPN -A MSSQLSvc/MyDBServer:1433 MyDomain\SQLServerService Replacing MyDBServer with the FQDN of the server and replacing MyDomain\SQLServerService with the name of my account. I then ran the query: SELECT s.session_id , c.connect_time , s.login_time , s.login_name , c.protocol_type , c.auth_scheme , s.HOST_NAME , s.program_name FROM sys.dm_exec_sessions s JOIN sys.dm_exec_connections c ON s.session_id = c.session_id This returns NTLM. So it's not Kerberos. What am I mising? The delegation tab is available for the account, so the spn bit worked perfectly fine. Is it not required to set some settings in the delegation tab? I've seen this in the case of setting kerberos for Sharepoint 2010 (which I intend to setup). Thanks

  • openCV Won't copy to image after changed color ( opencv and c++ )

    - by user1656647
    I am a beginner at opencv. I have this task: Make a new image Put a certain image in it at 0,0 Convert the certain image to gray scale put the grayscaled image next to it ( at 300, 0 ) This is what I did. I have a class imagehandler that has constructor and all the functions. cv::Mat m_image is the member field. Constructor to make new image: imagehandler::imagehandler(int width, int height) : m_image(width, height, CV_8UC3){ } Constructor to read image from file: imagehandler::imagehandler(const std::string& fileName) : m_image(imread(fileName, CV_LOAD_IMAGE_COLOR)) { if(!m_image.data) { cout << "Failed loading " << fileName << endl; } } This is the function to convert to grayscale: void imagehandler::rgb_to_greyscale(){ cv::cvtColor(m_image, m_image, CV_RGB2GRAY); } This is the function to copy paste image: //paste image to dst image at xloc,yloc void imagehandler::copy_paste_image(imagehandler& dst, int xLoc, int yLoc){ cv::Rect roi(xLoc, yLoc, m_image.size().width, m_image.size().height); cv::Mat imageROI (dst.m_image, roi); m_image.copyTo(imageROI); } Now, in the main, this is what I did : imagehandler CSImg(600, 320); //declare the new image imagehandler myimg(filepath); myimg.copy_paste_image(CSImg, 0, 0); CSImg.displayImage(); //this one showed the full colour image correctly myimg.rgb_to_greyscale(); myimg.displayImage(); //this shows the colour image in GRAY scale, works correctly myimg.copy_paste_image(CSImg, 300, 0); CSImg.displayImage(); // this one shows only the full colour image at 0,0 and does NOT show the greyscaled one at ALL! What seems to be the problem? I've been scratching my head for hours on this one!!!

  • Variable size encrypted container

    - by Cray
    Is there an application similar to TrueCrypt, but the one that can make variable size containers opposed to fixed-size or only-growing-to-certain-amount containers which can be made by TrueCrypt? I want this container to be able to be mounted to a drive/folder, and the size of the outer container not be much different from the total size of all the files that I put into the mounted folder, while still providing strong encryption. If to put it in other words, I want a program like truecrypt, which not only automatically grows the container if I put in new files, but also decreases it's size if some files are deleted. I know there are some issues of course, and it would not work 100% as truecrypt, because it basically works on the sector level of the disk, giving all the filesystem-control to the OS, and so when I remove a file, it might as well be left there, or there might be some fragmentation issues that would stop just truncating the volume from working, but perhaps a program can be built in some other way? Instead of providing sector-level interface, it would provide filesystem-level interface? A filesystem inside a file which would support shrinking when files are deleted?

  • jQuery not and classes

    - by Giles B
    Hi Guys, I have 2 anchor links (a.selector) and when one is clicked it has a class applied to it of 'active-arrow' and the click also removes the class of the same name from the other anchor as well as lowering the opacity to 0.2. I then want to have a fade effect when the user hovers over the anchor that doesn't have 'active-arrow' applied to it so that it goes to full opacity when mouseenters and back to 0.2 when mouseleaves. The problem im having is that both .not and :not don't seem to be working as expected, the hover effect works but if I click on the anchor whilst hovering the 'active-arrow' class is applied but when mouseleaves the opacity is faded down to 0.2 again even though the 'active-arrow' class is applied. Also the hover then doesn't work for the other a link which has had 'active-arrow' removed. Bit of a hard one to explain so heres some code that hopefully helps a bit. *//If a.selector doesn't have the class 'active-arrow' then run the hoverFade function* $("a.selector").not(".active-arrow").hoverFade(); //Functions for first element $('a.selector-1').click(function () { $('a.selector-2').removeClass('active-arrow'); //Remove background image from corresponding element $('ul#storage-items-2').fadeOut(1200).addClass('hide'); //Fade out then hide corresponding list $(this).addClass('active-arrow', 'fast'); //Add background image to current element $('ul#storage-items-1').removeClass('hide').fadeIn(1800); //Unhide and fade in the list $('a.selector-2').fadeTo(500, 0.2); //Fade corresponding element $(this).fadeTo(800, 1);//Fade this element to full opacity }); I only included the code for teh first anchor (a.selector-1) as the code for the second anchor is identical but just changes the class names to a.selector-2. Also the hoverFade function is in a seperate file so we can re-use it. jQuery.fn.hoverFade = function() { return this.each(function(){ $(this).hover( function () { $(this).fadeTo(500, 0.8); }, function () { $(this).fadeTo(500, 0.2); }); }); } Each anchor link fades in and fades out a UL as well. Any help is most appreciated Thanks Giles

  • Using ThreadPool.QueueUserWorkItem in ASP.NET in a high traffic scenario

    - by Michael Hart
    I've always been under the impression that using the ThreadPool for (let's say non-critical) short-lived background tasks was considered best practice, even in ASP.NET, but then I came across this article that seems to suggest otherwise - the argument being that you should leave the ThreadPool to deal with ASP.NET related requests. So here's how I've been doing small asynchronous tasks so far: ThreadPool.QueueUserWorkItem(s => PostLog(logEvent)) And the article is suggesting instead to create a thread explicitly, similar to: new Thread(() => PostLog(logEvent)){ IsBackground = true }.Start() The first method has the advantage of being managed and bounded, but there's the potential (if the article is correct) that the background tasks are then vying for threads with ASP.NET request-handlers. The second method frees up the ThreadPool, but at the cost of being unbounded and thus potentially using up too many resources. So my question is, is the advice in the article correct? If your site was getting so much traffic that your ThreadPool was getting full, then is it better to go out-of-band, or would a full ThreadPool imply that you're getting to the limit of your resources anyway, in which case you shouldn't be trying to start your own threads? Clarification: I'm just asking in the scope of small non-critical asynchronous tasks (eg, remote logging), not expensive work items that would require a separate process (in these cases I agree you'll need a more robust solution).

  • windows 2003 domain and windows xp

    - by ryju
    I had to move a computer account from one OU to another OU for the settings to be same as with other computers in the OU. After the computer account was moved to other domain, i reset the computer account. Now there is no domain access to this computer even using domain admin acccount. The error message is that windows cannot connect to domain because your computer account was not found.I reset the computer account again and that didnt make any difference. Local admin access was possilbe and i tried to change the computer to workgroup to join back to domain, but workgroup changing option is greyed out. Is there any way I can solve this issue. Thanks in advance.

  • Persistance JDO - How to query a property of a collection with JDOQL?

    - by Sergio del Amo
    I want to build an application where a user identified by an email address can have several application accounts. Each account can have one o more users. I am trying to use the JDO Storage capabilities with Google App Engine Java. Here is my attempt: @PersistenceCapable @Inheritance(strategy = InheritanceStrategy.NEW_TABLE) public class AppAccount { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Long id; @Persistent private String companyName; @Persistent List<Invoices> invoices = new ArrayList<Invoices>(); @Persistent List<AppUser> users = new ArrayList<AppUser>(); // Getter Setters and Other Fields } @PersistenceCapable @EmbeddedOnly public class AppUser { @Persistent private String username; @Persistent private String firstName; @Persistent private String lastName; // Getter Setters and Other Fields } When a user logs in, I want to check how many accounts does he belongs to. If he belongs to more than one he will be presented with a dashboard where he can click which account he wants to load.

  • Gridview empty when SelectedIndexChanged called

    - by xan
    I have a DataGrid which is being bound dynamically to a database query. The user enters some search text into a text field, clicks search, and the code behind creates the appropriate database query using LINQ (searches a table based on the string and returns a limited set of the columns). It then sets the GridView datasource to be the query and calls DataBind(). protected void btnSearch_Click(object sender, EventArgs e) { var query = from record in DB.Table where record.Name.Contains(txtSearch.Text) //Extra string checking etc. removed. select new { record.ID, record.Name, record.Date }; gvResults.DataSource = query; gvResults.DataBind(); } This works fine. When a user selects a row in the grid, the SelectedIndexChanged event handler gets the id from the row in the grid (one of the fields), queries the full record from the DB and then populates a set of editor / details fields with the records full details. protected void gvResults_SelectedIndexChanged(object sender, EventArgs e) { int id = int.Parse(gvResults.SelectedRow.Cells[1].Text); DisplayDetails(id); } This works fine on my local machine where I'm developing the code. On the production server however, the function is called successfully, but the row and column count on gvResults, the GridVeiw is 0 - the table is empty. The GridView's viewstate is enabled and I can't see obvious differences. Have I made some naive assumptions, or am I relying on something that is likely to be configured differently in debug? Locally I am running an empty asp.net web project in VS2008 to make development quicker. The production server is running the sitecore CMS so is configured rather differently. Any thoughts or suggestions would be most welcome. Thanks in advance!

  • Samba 3.3 or later on Slackware 12 - how do I make this happen?

    - by caroulia
    I'm trying to upgrade the Samba server on a Slackware 12 box to serve as PDC for Windows 7 32bit machines (it now has a 3.0.3 and does the job for Win XP machines, but 7 refuses to join the domain - I'm posting this after having tried a few dozen hacks on the windows registry). I'm a newbie on Slackware (I usually dwell in Ubuntu) so I may be going about this the wrong way but this is what I've done so far: The Samba wiki has a couple of hacks for the registry and also seems to suggest a version later than 3.3 (though not in so many words) http://wiki.samba.org/index.php/Windows7 Having scoured the net for later Samba binaries for Slackware 12 and gotten precisely nowhere, I decided that maybe I could compile the blessed thing. But I keep on getting compiler errors. I'm using this SlackBuild script http://ftp.twaren.net/Linux/slackware/slackware-current/source/n/samba/samba.SlackBuild Is there a better way to make this happen? (without upgrading the base system? it has so many finely tuned things running that I don't want to mess with the rest of the setup).

  • Capistrano deploying to different servers with different authentication methods

    - by marimaf
    I need to deploy to 2 different server and these 2 servers have different authentication methods (one is my university's server and the other is an amazon web server AWS) I already have running capistrano for my university's server, but I don't know how to add the deployment to AWS since for this one I need to add ssh options for example to user the .pem file, like this: ssh_options[:keys] = [File.join(ENV["HOME"], ".ssh", "test.pem")] ssh_options[:forward_agent] = true I have browsed starckoverflow and no post mention about how to deal with different authentication methods this and this I found a post that talks about 2 different keys, but this one refers to a server and a git, both usings different pem files. This is not the case. I got to this tutorial, but couldn't find what I need. I don't know if this is relevant for what I am asking: I am working on a rails app with ruby 1.9.2p290 and rails 3.0.10 and I am using an svn repository Please any help os welcome. Thanks a lot

  • How can I poll different aws sqs in the same process?

    - by Luccas
    What is the right way to poll from differents AWS SQS in the same process? Suppose I have a ruby script: listen_queues.rb and run it. Should I need to create threads to wrap each SQS poll or start sub processes? t1 = Thread.new do queue1.poll do |msg| .... end t2 = Thread.new do queue2.poll do |msg| .... end t2.join I tried this code, but the poll is not receiving any of the messages available. When I run only one of them (t1 or t2), it works. But I need the 2 running. What is going on? Thanks!!

  • Agile and Scrum burning me down please help me figuring out the truth

    - by jadook
    hi all, in the last while I installed MS-TFS 2008 then started to get myself prepared to use Agile Process Guidance template shipped with the TFS. with little googling I passed through Mike Cohn materials: I watched his conference in youtube "sponsored by google: http://www.youtube.com/watch?v=fb9Rzyi8b90 http://www.youtube.com/watch?v=jeT0pOVg0EI Read his book "Agile Estimating and Planning" Watching the video series in his website: http://www.mountaingoatsoftware.com/presentations-tag/video-recorded I was very happy while absorbing and eating the techniques he is using with the teams and how agile and scrum is such a great software process/methodology until I saw Mike answering a question regarding an architect role and talking about the requirements document... at that point everything start falling apart due to the following: Last year I had been assigned to make full analysis "including requirements gathering" for big project "very high priority project". within 2 months of hardwork, dedication and commitment I delivered the whole analysis with full satisfaction of the customer and my BOSS and ZERO amendments. Later on, the project entered the architecting, development ... phases. due to the fact that the system included many competitive and exciting features I requested patenting it and its going in the process... so imagine you are the kind of person who used to love facing all kind of challenges and returning with excellent experience and results for the stakeholders and yourself, How fairly agile and scrum processes will credit and admit your talent and passion while the scrum master/coach treat the team as one unit that accomplish user stories and converge through trial and error approach??!!!! with that dark thoughts about agile and scrum I found many people "anti agile" and on top of them is "Crispin Rogers Johnson": http://agile-crispin.blogspot.com/ that guy made anti statement for everything Mike Cohn used to talk about. I really don't know what to do next! so any guidance will be appreciated. Thanks,
