  • How to retain secondary hard drive mounts at reboot and keep shares?

    - by Tom
    I'm running Ubuntu 12.04. A second hard drive connected to this computer does not mount when the computer boots. Additionally, I have set up the drive to be shared but the share is not retained, the share is lost after each boot. My main system drive and a removable drive mount OK and shares remain between boots. Additional information follows: D2Linux sda1 is the secondary hard drive L-Freeagent sdc1 is the removeable drive Here is the contents of fstab immediately after booting (D2Linux /dev/sda1 not yet mounted): '# /etc/fstab: static file system information.

  • 14.04 LTS Unity no longer boots after last 94 MB update

    - by Harryg123
    I am running 14.04 LTS, Unity, on an HP Pavillion 15, 4GBRAM, 750 GB hdd, I-5 machine, with AMD 8600M graphics card built in. I have disabled the dash and all Ubuntu spyware. I have been faithfully loading all updates as they appear. This morning it asked for a 94 MB update (bringing kernel to .27, I think. Now, I can boot, get to login screen, but it freezes after that. Keyboard doesn't work at that point, but mouse does. I booted into recovery mode, tried to run in generic graphics mode, -- system again froze. I also pressed [esc] during boot, but saw nothing strange; then text disappeared and was replaced by login screen. I am not a hobbyist; this is a production machine and I have a lot of work to do today. Having a standard software update render my machine completely useless... sigh. Perhaps the simplest thing to do would be to revert to the previous configuration. How do I do that? I can boot into recovery mode. But I have no idea how to proceed. TIA for all help. -Harry

  • HP Pavilion 15 with AMD dual graphics - Ubuntu live environment not starting

    - by creepus
    I've had this laptop for about a day now and have decided to try Ubuntu on it and determine if I want to install it. I created a USB, it booted (Secure Boot was on, I tried with Secure Boot off to no effect), and then the problem occurred. The screen turned off for a second, turned back on to a black screen, shut off again and turned back on with a dialogue box telling me that the system had to use low-graphics mode. I clicked OK, selected low-graphics mode from the menu and clicked OK. The screen switched to the boot messages and did not go any further than this. Ctrl+Alt+DEL started rebooting the laptop though. I tried booting again, but this time I edited the boot options in GRUB to add nomodeset. This time, the laptop only booted to a black screen. Ctrl+Alt+F2 took me to a prompt, I tried startx from there, but X didn't start, complaining that it wanted kernel mode setting back. I can not seem to find any option to disable one graphics chip or the other in the UEFI setup menus. Laptop : HP Pavilion 15-E004AU. The CPU : AMD A6-4400M APU with Radeon(tm) HD Graphics The graphics chip : AMD Radeon HD 7520G + 8670M Dual Graphics. The Ubuntu version : 13.10, 64 bit. Thanks. EDIT: I tried 12.04.3 LTS, it managed to bring the desktop up. There are severe graphics glitches after about two minutes though.

  • Cannot access the filesystems using LiveCD (LVM2,EXT2)

  • Limiting the speed of the mouse cursor

    - by idlewire
    I am working on a simple game where you can drag objects around with the mouse cursor. As I drag the object around quickly, I notice there is some juddering, which seems to be due to the fact that I can move the mouse cursor faster than the game's update/draw. So, although I maintain the offset from where the player initially clicked on the object, the mouse's relative position to the object shifts around slightly before settling as I move the object very quickly. The only way I have found to get smooth, exact 1:1 movement is if I turn both IsFixedTimeStep and SynchronizeWithVerticalRetrace to false. However, I'd rather not have to do that. I have also tried making a custom mouse cursor, hiding the real mouse, taking the real mouse delta and clamping it to a maximum speed. Here is the problem: In windowed mode, the "real" mouse cursor moves off the window while the custom mouse cursor (since it's movement is being scaled) is still somewhere inside the game window. This becomes bizarre and is obviously not desired, as clicking at this point means clicking on things outside the game window. Is there any way to accomplish this in windowed mode? In fullscreen mode, the "real" mouse cursor is bounded to the edges of the screen. So I get to a point where there is no more mouse delta, yet my custom cursor is still somewhere in the middle of the screen and hence can't move further in that direction. If I wanted to clamp it to the edge of the screen when the real cursor is at the edge, then I would get an abrupt jump to the edge of the screen, which isn't desired either Any help would be appreciated. I'd like to be able to limit the speed of the mouse, but also would appreciate help with the first issue (the non-smooth relative offset between mouse cursor movement and object movement).

  • WPF DataGrid using a DataGridTemplateColumn rather than a DataGridComboBoxColumn to show selected value at load

    - by T
    My problem was that using a DataGridComboBoxColumn I couldn’t get it to show the selected value when the DataGrid loaded.  Instead, the user would have to click in the cells and like magic, the current selected values would appear and it looked the way I wanted it to on load. Here is what I had <DataGridComboBoxColumn MinWidth="150" x:Name="crewColumn" Header="Crew" ItemsSource="{Binding JobEdit.Crews, Source={StaticResource Locator}}" DisplayMemberPath="Name" SelectedItemBinding="{Binding JobEdit.SelectedCrew, Mode=TwoWay, Source={StaticResource Locator}}" />   Here is what I changed it too.  This works great.  It displays the selected item when the DataGrid loads and shows the combo box when the user goes into edit mode.   <DataGridTemplateColumn Header="Crew" MinWidth="150"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Crew.Name}"></TextBlock> </DataTemplate> </DataGridTemplateColumn.CellTemplate> <DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <ComboBox ItemsSource="{Binding JobEdit.Crews, Source={StaticResource Locator}}" DisplayMemberPath="Name" SelectedItem="{Binding JobEdit.SelectedCrew, Mode=TwoWay, Source={StaticResource Locator}}"></ComboBox> </DataTemplate> </DataGridTemplateColumn.CellEditingTemplate> </DataGridTemplateColumn>

  • Speed up ADF Mobile Deployment to Android with Keystore

    - by Shay Shmeltzer
    As you might have noticed from my latest ADF Mobile entries, I'm doing most of my ADF Mobile development on a windows machine and testing on an Android device. Unfortunately the Android/windows experience is not as fast as the iOS/Mac one. However, there is one thing I learned today that can make this a bit less painful in terms of the speed to deploy and test your application - and this is to use the "Release" mode when deploying your application instead of the "Debug" mode. To do this you'll first need to define a keystore, but as Joe from our Mobile team showed me today, this is quite easy. Here are the steps: Open a command line in your JDK bin directory (I just used the JDK that comes with the JDeveloper install). Issue the following command: keytool –genkey –v –keystore <Keystore Name>.keystore –alias <Alias Name> -keyalg RSA –keysize 2048 –validity 10000 Both keystore name and alias names are strings that you decide on. The keytool utility will then prompt you with various questions that you'll need to answer. Once this is done, the next step is to configure your JDeveloper preferences->ADF Mobile to add this keystore there under the release tab:  Then for your application specific deployment profile - switch the build mode from debug to release. The end result is a much smaller mobile application (for example from 60 to 21mb) and a much faster deployment cycle (for me it is about twice as fast as before).

  • How do I fix broken installation?

    - by Daniel
    Let me start off by saying I'm dual booting 11.04 and Windows 7 on a Thinkpad T61p. The problem may have arisen when I hit the power button during normal startup. I'm fully aware how stupid this is. I don't know why I did it. I did it. Now, I can't get in to Ubuntu. Windows works fine. But when I try to start Ubuntu normally, it seems to run some checks, and does not start up. Sometimes, I see a black screen, and it tells me that it's running certain checks, and then, [ok]. Like... Battery Check Somethingorother [ok] It'll give me 1-5 of these. And then it just does nothing, and I have to turn it off. When I try to start in safe mode... I tried low graphics mode, and after going through a couple of dialogue boxes, I'm brought right back to the safe mode dialogue box. And if I hit 'resume,' a shell pushes up (still that grey on black "your computer is broken" type shell) and asks me to log in. I do, and try to run unity. It tells me something along the lines of: WARNING no DISPLAY variable set and then sets it to " :0" , which doesn't work. And then I can't do anything, really, and I have to restart. (I don't know how to do this from the command line, so I just hard reset. That command would be helpful). Does anybody have any idea how I can get Ubuntu working right again? FTP is less pleasant in Explorer than it is in Nautilus or w/e it is now.

  • How to start Ubuntu with no working video card?

    - by ViliusK
    I have a laptop with broken video card. It has two operating systems installed - Windows 7 and Ubuntu 10.10 Desktop Edition. It has GRUB to manage which operating system to boot up. Windows is default OS. And Windows fails to boot up without video card. I'm checking with ping to the ports which are shown as used by DHCP in my router. Normal boot of Ubuntu also fails and it restarts after a while. But when I choose (blindly, but checking HDD indicator and by counting button presses when GRUB menu appears) to boot second option of Ubuntu (rescue mode) it starts and I can ping it. But when I try to connect to it through SSH, I'm getting "connection refused" error from putty. I've took out HDD from my laptop already and inserted it to WD Passport case so now I can connect it to other computer to edit configuration files. How can I check if SSH server is working? How to enable it in rescue mode? Or better, how to disable video card to be required while booting Ubuntu in normal mode?

  • External Full HD monitor and Virtual Desktop Size

    - by Stefan
    I have two FullHD monitors attached to my ATI graphics card [2]. The resolution of both of them is detected properly without any modifications to /etc/X11/xorg.conf. I can run both of them in clone mode. However, when I try to run them next to each other, I got the following error: The selected configuration for displays could not be applied. If tried to fix this according to [1]. My xorg.conf now looks like this: Section "Module" Load "glx" EndSection Section "Screen" Identifier "Default Screen" DefaultDepth 24 SubSection "Display" # The 1088 is the smallest multiple of 32 >= 1088 # see manpages Virtual 1920 1088 EndSubSection EndSection This does not seem to be parsed properly. After restarting X, I cannot set resolutions beyond 1600 or so any more. /var/log/Xorg.0.log gives: [ 15.676] (II) fglrx(0): Not using mode "1920x1080" (width too large for virtual size) [ 15.676] (II) fglrx(0): Not using mode "1680x1050" (width too large for virtual size) Are my modifications syntactically incorrect?

  • Can't install Ubuntu in Windows 8

    - by user171635
    I’ve been trying to install Ubuntu 13.04 64-bit edition on an ASUS (K53Z) laptop. I have Windows 8 64-bit installed in a non UEFI mode (I think since it starts-up with the Windows logo and I don’t have the UEFI settings). This laptop had installed Windows 7 and when I upgraded it I didn’t knew about the UEFI advantages. I tried several times to install Ubuntu from a USB device and it loads the logo and then I can’t go further in the installation. I thought it was the version of Ubuntu and tried to install Fedora (even if I personally prefer Ubuntu). I had the same problem: Fedora’s logo appears and it gets stuck. I tried also to boot from different USB devices and didn’t work either. My Bios has EFI options to boot but they were not enabled. So I tried to enable them to boot the USB in UEFI mode. A menu shows up with the options of install Ubuntu and try Ubuntu. If I click the Install or try option, I get a black screen and I can’t go further with the install (which I think is normal since I don’t have Windows 8 in EFI mode). My hypothesis is that the Bios isn’t letting Ubuntu write or read from my SSD, because the activity LED in the USB memory is on when it’s loading the installation files. Once the files are ready and the Ubuntu logo is loaded I don’t see a LED activity on neither the SSD or the USB. Thanks If I missed data you can ask me.

  • Extended display - nightmare

    - by user206343
    I have been struggling for quite a while, and I hope one of you can shed some lights on my issue. I am using Xubuntu 13.10 (Ubuntu 12.04LTS behaves the same way, higher version wouldn't install, LinuxMint didn't install, Fedora didn't install). I am trying to set extend display for two dell monitors 1900x1200. It works great when in mirror mode, but I just cannot extend the display. Either one monitor goes to sleep and the other is unresponsive, or both work but are unusable. This is a link to the picture of my monitors in mirror mode This is link showing what happens after I try to extend the desktop I get the same results if I use aRandr or the built in configuration utility. I have an ATI Radeon X300 card. I cannot use proprietary Catalyst drivers (I would have to use the legacy ones, which would force me into using much older version of the OS). Extension is possible with Windows. I am hoping someone can come up with tweaks that would allow me to run an extended desktop. I truly love Xubuntu (and Ubuntu, unfortunately, Unity is a bit too heavy for my old PC, and I have to run in 2D mode, so 12.04 is as high as I can go). I have tried everything I could find online, but nothing worked thus far. I believe some configuration or something I am missing might work. Please, if you have any idea, do not hesitate. Thanks guys.

  • Creating STA COM compatible ASP.NET Applications

    - by Rick Strahl
    When building ASP.NET applications that interface with old school COM objects like those created with VB6 or Visual FoxPro (MTDLL), it's extremely important that the threads that are serving requests use Single Threaded Apartment Threading. STA is a COM built-in technology that allows essentially single threaded components to operate reliably in a multi-threaded environment. STA's guarantee that COM objects instantiated on a specific thread stay on that specific thread and any access to a COM object from another thread automatically marshals that thread to the STA thread. The end effect is that you can have multiple threads, but a COM object instance lives on a fixed never changing thread. ASP.NET by default uses MTA (multi-threaded apartment) threads which are truly free spinning threads that pay no heed to COM object marshaling. This is vastly more efficient than STA threading which has a bit of overhead in determining whether it's OK to run code on a given thread or whether some sort of thread/COM marshaling needs to occur. MTA COM components can be very efficient, but STA COM components in a multi-threaded environment always tend to have a fair amount of overhead. It's amazing how much COM Interop I still see today so while it seems really old school to be talking about this topic, it's actually quite apropos for me as I have many customers using legacy COM systems that need to interface with other .NET applications. In this post I'm consolidating some of the hacks I've used to integrate with various ASP.NET technologies when using STA COM Components. STA in ASP.NET Support for STA threading in the ASP.NET framework is fairly limited. Specifically only the original ASP.NET WebForms technology supports STA threading directly via its STA Page Handler implementation or what you might know as ASPCOMPAT mode. For WebForms running STA components is as easy as specifying the ASPCOMPAT attribute in the @Page tag:<%@ Page Language="C#" AspCompat="true" %> which runs the page in STA mode. Removing it runs in MTA mode. Simple. Unfortunately all other ASP.NET technologies built on top of the core ASP.NET engine do not support STA natively. So if you want to use STA COM components in MVC or with class ASMX Web Services, there's no automatic way like the ASPCOMPAT keyword available. So what happens when you run an STA COM component in an MTA application? In low volume environments - nothing much will happen. The COM objects will appear to work just fine as there are no simultaneous thread interactions and the COM component will happily run on a single thread or multiple single threads one at a time. So for testing running components in MTA environments may appear to work just fine. However as load increases and threads get re-used by ASP.NET COM objects will end up getting created on multiple different threads. This can result in crashes or hangs, or data corruption in the STA components which store their state in thread local storage on the STA thread. If threads overlap this global store can easily get corrupted which in turn causes problems. STA ensures that any COM object instance loaded always stays on the same thread it was instantiated on. What about COM+? COM+ is supposed to address the problem of STA in MTA applications by providing an abstraction with it's own thread pool manager for COM objects. It steps in to the COM instantiation pipeline and hands out COM instances from its own internally maintained STA Thread pool. This guarantees that the COM instantiation threads are STA threads if using STA components. COM+ works, but in my experience the technology is very, very slow for STA components. It adds a ton of overhead and reduces COM performance noticably in load tests in IIS. COM+ can make sense in some situations but for Web apps with STA components it falls short. In addition there's also the need to ensure that COM+ is set up and configured on the target machine and the fact that components have to be registered in COM+. COM+ also keeps components up at all times, so if a component needs to be replaced the COM+ package needs to be unloaded (same is true for IIS hosted components but it's more common to manage that). COM+ is an option for well established components, but native STA support tends to provide better performance and more consistent usability, IMHO. STA for non supporting ASP.NET Technologies As mentioned above only WebForms supports STA natively. However, by utilizing the WebForms ASP.NET Page handler internally it's actually possible to trick various other ASP.NET technologies and let them work with STA components. This is ugly but I've used each of these in various applications and I've had minimal problems making them work with FoxPro STA COM components which is about as dififcult as it gets for COM Interop in .NET. In this post I summarize several STA workarounds that enable you to use STA threading with these ASP.NET Technologies: ASMX Web Services ASP.NET MVC WCF Web Services ASP.NET Web API ASMX Web Services I start with classic ASP.NET ASMX Web Services because it's the easiest mechanism that allows for STA modification. It also clearly demonstrates how the WebForms STA Page Handler is the key technology to enable the various other solutions to create STA components. Essentially the way this works is to override the WebForms Page class and hijack it's init functionality for processing requests. Here's what this looks like for Web Services:namespace FoxProAspNet { public class WebServiceStaHandler : System.Web.UI.Page, IHttpAsyncHandler { protected override void OnInit(EventArgs e) { IHttpHandler handler = new WebServiceHandlerFactory().GetHandler( this.Context, this.Context.Request.HttpMethod, this.Context.Request.FilePath, this.Context.Request.PhysicalPath); handler.ProcessRequest(this.Context); this.Context.ApplicationInstance.CompleteRequest(); } public IAsyncResult BeginProcessRequest( HttpContext context, AsyncCallback cb, object extraData) { return this.AspCompatBeginProcessRequest(context, cb, extraData); } public void EndProcessRequest(IAsyncResult result) { this.AspCompatEndProcessRequest(result); } } public class AspCompatWebServiceStaHandlerWithSessionState : WebServiceStaHandler, IRequiresSessionState { } } This class overrides the ASP.NET WebForms Page class which has a little known AspCompatBeginProcessRequest() and AspCompatEndProcessRequest() method that is responsible for providing the WebForms ASPCOMPAT functionality. These methods handle routing requests to STA threads. Note there are two classes - one that includes session state and one that does not. If you plan on using ASP.NET Session state use the latter class, otherwise stick to the former. This maps to the EnableSessionState page setting in WebForms. This class simply hooks into this functionality by overriding the BeginProcessRequest and EndProcessRequest methods and always forcing it into the AspCompat methods. The way this works is that BeginProcessRequest() fires first to set up the threads and starts intializing the handler. As part of that process the OnInit() method is fired which is now already running on an STA thread. The code then creates an instance of the actual WebService handler factory and calls its ProcessRequest method to start executing which generates the Web Service result. Immediately after ProcessRequest the request is stopped with Application.CompletRequest() which ensures that the rest of the Page handler logic doesn't fire. This means that even though the fairly heavy Page class is overridden here, it doesn't end up executing any of its internal processing which makes this code fairly efficient. In a nutshell, we're highjacking the Page HttpHandler and forcing it to process the WebService process handler in the context of the AspCompat handler behavior. Hooking up the Handler Because the above is an HttpHandler implementation you need to hook up the custom handler and replace the standard ASMX handler. To do this you need to modify the web.config file (here for IIS 7 and IIS Express): <configuration> <system.webServer> <handlers> <remove name="WebServiceHandlerFactory-Integrated-4.0" /> <add name="Asmx STA Web Service Handler" path="*.asmx" verb="*" type="FoxProAspNet.WebServiceStaHandler" precondition="integrated"/> </handlers> </system.webServer> </configuration> (Note: The name for the WebServiceHandlerFactory-Integrated-4.0 might be slightly different depending on your server version. Check the IIS Handler configuration in the IIS Management Console for the exact name or simply remove the handler from the list there which will propagate to your web.config). For IIS 5 & 6 (Windows XP/2003) or the Visual Studio Web Server use:<configuration> <system.web> <httpHandlers> <remove path="*.asmx" verb="*" /> <add path="*.asmx" verb="*" type="FoxProAspNet.WebServiceStaHandler" /> </httpHandlers> </system.web></configuration> To test, create a new ASMX Web Service and create a method like this: [WebService(Namespace = "http://foxaspnet.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class FoxWebService : System.Web.Services.WebService { [WebMethod] public string HelloWorld() { return "Hello World. Threading mode is: " + System.Threading.Thread.CurrentThread.GetApartmentState(); } } Run this before you put in the web.config configuration changes and you should get: Hello World. Threading mode is: MTA Then put the handler mapping into Web.config and you should see: Hello World. Threading mode is: STA And you're on your way to using STA COM components. It's a hack but it works well! I've used this with several high volume Web Service installations with various customers and it's been fast and reliable. ASP.NET MVC ASP.NET MVC has quickly become the most popular ASP.NET technology, replacing WebForms for creating HTML output. MVC is more complex to get started with, but once you understand the basic structure of how requests flow through the MVC pipeline it's easy to use and amazingly flexible in manipulating HTML requests. In addition, MVC has great support for non-HTML output sources like JSON and XML, making it an excellent choice for AJAX requests without any additional tools. Unlike WebForms ASP.NET MVC doesn't support STA threads natively and so some trickery is needed to make it work with STA threads as well. MVC gets its handler implementation through custom route handlers using ASP.NET's built in routing semantics. To work in an STA handler requires working in the Page Handler as part of the Route Handler implementation. As with the Web Service handler the first step is to create a custom HttpHandler that can instantiate an MVC request pipeline properly:public class MvcStaThreadHttpAsyncHandler : Page, IHttpAsyncHandler, IRequiresSessionState { private RequestContext _requestContext; public MvcStaThreadHttpAsyncHandler(RequestContext requestContext) { if (requestContext == null) throw new ArgumentNullException("requestContext"); _requestContext = requestContext; } public IAsyncResult BeginProcessRequest(HttpContext context, AsyncCallback cb, object extraData) { return this.AspCompatBeginProcessRequest(context, cb, extraData); } protected override void OnInit(EventArgs e) { var controllerName = _requestContext.RouteData.GetRequiredString("controller"); var controllerFactory = ControllerBuilder.Current.GetControllerFactory(); var controller = controllerFactory.CreateController(_requestContext, controllerName); if (controller == null) throw new InvalidOperationException("Could not find controller: " + controllerName); try { controller.Execute(_requestContext); } finally { controllerFactory.ReleaseController(controller); } this.Context.ApplicationInstance.CompleteRequest(); } public void EndProcessRequest(IAsyncResult result) { this.AspCompatEndProcessRequest(result); } public override void ProcessRequest(HttpContext httpContext) { throw new NotSupportedException("STAThreadRouteHandler does not support ProcessRequest called (only BeginProcessRequest)"); } } This handler code figures out which controller to load and then executes the controller. MVC internally provides the information needed to route to the appropriate method and pass the right parameters. Like the Web Service handler the logic occurs in the OnInit() and performs all the processing in that part of the request. Next, we need a RouteHandler that can actually pick up this handler. Unlike the Web Service handler where we simply registered the handler, MVC requires a RouteHandler to pick up the handler. RouteHandlers look at the URL's path and based on that decide on what handler to invoke. The route handler is pretty simple - all it does is load our custom handler: public class MvcStaThreadRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { if (requestContext == null) throw new ArgumentNullException("requestContext"); return new MvcStaThreadHttpAsyncHandler(requestContext); } } At this point you can instantiate this route handler and force STA requests to MVC by specifying a route. The following sets up the ASP.NET Default Route:Route mvcRoute = new Route("{controller}/{action}/{id}", new RouteValueDictionary( new { controller = "Home", action = "Index", id = UrlParameter.Optional }), new MvcStaThreadRouteHandler()); RouteTable.Routes.Add(mvcRoute);   To make this code a little easier to work with and mimic the behavior of the routes.MapRoute() functionality extension method that MVC provides, here is an extension method for MapMvcStaRoute(): public static class RouteCollectionExtensions { public static void MapMvcStaRoute(this RouteCollection routeTable, string name, string url, object defaults = null) { Route mvcRoute = new Route(url, new RouteValueDictionary(defaults), new MvcStaThreadRouteHandler()); RouteTable.Routes.Add(mvcRoute); } } With this the syntax to add  route becomes a little easier and matches the MapRoute() method:RouteTable.Routes.MapMvcStaRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); The nice thing about this route handler, STA Handler and extension method is that it's fully self contained. You can put all three into a single class file and stick it into your Web app, and then simply call MapMvcStaRoute() and it just works. Easy! To see whether this works create an MVC controller like this: public class ThreadTestController : Controller { public string ThreadingMode() { return Thread.CurrentThread.GetApartmentState().ToString(); } } Try this test both with only the MapRoute() hookup in the RouteConfiguration in which case you should get MTA as the value. Then change the MapRoute() call to MapMvcStaRoute() leaving all the parameters the same and re-run the request. You now should see STA as the result. You're on your way using STA COM components reliably in ASP.NET MVC. WCF Web Services running through IIS WCF Web Services provide a more robust and wider range of services for Web Services. You can use WCF over HTTP, TCP, and Pipes, and WCF services support WS* secure services. There are many features in WCF that go way beyond what ASMX can do. But it's also a bit more complex than ASMX. As a basic rule if you need to serve straight SOAP Services over HTTP I 'd recommend sticking with the simpler ASMX services especially if COM is involved. If you need WS* support or want to serve data over non-HTTP protocols then WCF makes more sense. WCF is not my forte but I found a solution from Scott Seely on his blog that describes the progress and that seems to work well. I'm copying his code below so this STA information is all in one place and quickly explain. Scott's code basically works by creating a custom OperationBehavior which can be specified via an [STAOperation] attribute on every method. Using his attribute you end up with a class (or Interface if you separate the contract and class) that looks like this: [ServiceContract] public class WcfService { [OperationContract] public string HelloWorldMta() { return Thread.CurrentThread.GetApartmentState().ToString(); } // Make sure you use this custom STAOperationBehavior // attribute to force STA operation of service methods [STAOperationBehavior] [OperationContract] public string HelloWorldSta() { return Thread.CurrentThread.GetApartmentState().ToString(); } } Pretty straight forward. The latter method returns STA while the former returns MTA. To make STA work every method needs to be marked up. The implementation consists of the attribute and OperationInvoker implementation. Here are the two classes required to make this work from Scott's post:public class STAOperationBehaviorAttribute : Attribute, IOperationBehavior { public void AddBindingParameters(OperationDescription operationDescription, System.ServiceModel.Channels.BindingParameterCollection bindingParameters) { } public void ApplyClientBehavior(OperationDescription operationDescription, System.ServiceModel.Dispatcher.ClientOperation clientOperation) { // If this is applied on the client, well, it just doesn’t make sense. // Don’t throw in case this attribute was applied on the contract // instead of the implementation. } public void ApplyDispatchBehavior(OperationDescription operationDescription, System.ServiceModel.Dispatcher.DispatchOperation dispatchOperation) { // Change the IOperationInvoker for this operation. dispatchOperation.Invoker = new STAOperationInvoker(dispatchOperation.Invoker); } public void Validate(OperationDescription operationDescription) { if (operationDescription.SyncMethod == null) { throw new InvalidOperationException("The STAOperationBehaviorAttribute " + "only works for synchronous method invocations."); } } } public class STAOperationInvoker : IOperationInvoker { IOperationInvoker _innerInvoker; public STAOperationInvoker(IOperationInvoker invoker) { _innerInvoker = invoker; } public object[] AllocateInputs() { return _innerInvoker.AllocateInputs(); } public object Invoke(object instance, object[] inputs, out object[] outputs) { // Create a new, STA thread object[] staOutputs = null; object retval = null; Thread thread = new Thread( delegate() { retval = _innerInvoker.Invoke(instance, inputs, out staOutputs); }); thread.SetApartmentState(ApartmentState.STA); thread.Start(); thread.Join(); outputs = staOutputs; return retval; } public IAsyncResult InvokeBegin(object instance, object[] inputs, AsyncCallback callback, object state) { // We don’t handle async… throw new NotImplementedException(); } public object InvokeEnd(object instance, out object[] outputs, IAsyncResult result) { // We don’t handle async… throw new NotImplementedException(); } public bool IsSynchronous { get { return true; } } } The key in this setup is the Invoker and the Invoke method which creates a new thread and then fires the request on this new thread. Because this approach creates a new thread for every request it's not super efficient. There's a bunch of overhead involved in creating the thread and throwing it away after each thread, but it'll work for low volume requests and insure each thread runs in STA mode. If better performance is required it would be useful to create a custom thread manager that can pool a number of STA threads and hand off threads as needed rather than creating new threads on every request. If your Web Service needs are simple and you need only to serve standard SOAP 1.x requests, I would recommend sticking with ASMX services. It's easier to set up and work with and for STA component use it'll be significantly better performing since ASP.NET manages the STA thread pool for you rather than firing new threads for each request. One nice thing about Scotts code is though that it works in any WCF environment including self hosting. It has no dependency on ASP.NET or WebForms for that matter. STA - If you must STA components are a  pain in the ass and thankfully there isn't too much stuff out there anymore that requires it. But when you need it and you need to access STA functionality from .NET at least there are a few options available to make it happen. Each of these solutions is a bit hacky, but they work - I've used all of them in production with good results with FoxPro components. I hope compiling all of these in one place here makes it STA consumption a little bit easier.

    Here's the tkprof output for a query that's running extremely slowly (WARNING: it's long :-) ): SELECT mbr_comment_idn, mbr_crt_dt, mbr_data_source, mbr_dol_bl_rmo_ind, mbr_dxcg_ctl_member,

******************************************************************************** Based on my reading of Oracle's documentation of skip scans, a skip scan is most useful when the first column of an index has a low number of unique values. The thing is that the first index of this column is a unique primary key. So am I correct in assuming that a skip scan is the wrong thing to do here? Also, what kind of scan should it be doing? Should I do some more hinting for this query? EDIT: I should also point out that the query's where clause uses the columns in IDX_MBR_IDENTFN and no columns other than what's in that index. So as far as I can tell, I'm not skipping any columns.

  • proftpd, dynamic IP, and filezilla: port troubles

    - by Yami
    The basic setup: Two computers, one running proftpd, one attempting to connect via filezilla. Both linux (xubuntu on the server, kubuntu on the client). Both are at the moment behind a router on a residential (read: dynamic IP) connection; the client is a laptop I plan to take away from the home network, so I'll need this to work externally. I have my router set up to allow specific ports forwarded to each machine and, where possible, have plugged in those numbers into proftpd (via gadmin, double-checking the config file) and filezilla. Attempting to connect via active mode using the internal IP works: Status: Connecting to 192.168.1.139:8085... Status: Connection established, waiting for welcome message... Response: 220 Crossroads FTP Command: USER <redacted> Response: 331 Password required for <redacted> Command: PASS ******* Response: 230 Anonymous access granted, restrictions apply Command: OPTS UTF8 ON Response: 200 UTF8 set to on Status: Connected Status: Retrieving directory listing... Command: PWD Response: 257 "/" is the current directory Command: TYPE I Response: 200 Type set to I Command: PORT 192,168,1,52,153,140 Response: 200 PORT command successful Command: LIST Response: 150 Opening ASCII mode data connection for file list Response: 226 Transfer complete Status: Directory listing successful Attempting to connect via the domain name, however, leads to issues; in active mode, the PORT is the last command to be received according to the server's logs, and in passive mode, it's the PASV command. This leads me to believe I'm being redirected to a bad port? Active Sample: Status: Resolving address of <url> Status: Connecting to <ip:port> Status: Connection established, waiting for welcome message... Response: 220 Crossroads FTP Command: USER <redacted> Response: 331 Password required for <redacted> Command: PASS ******* Response: 230 Anonymous access granted, restrictions apply Command: OPTS UTF8 ON Response: 200 UTF8 set to on Status: Connected Status: Retrieving directory listing...

Command: PWD Response: 257 "/" is the current directory Command: TYPE I Response: 200 Type set to I Command: PASV Response: 227 Entering Passive Mode (64,95,64,197,101,88). Command: LIST Error: Connection timed out Error: Failed to retrieve directory listing In both cases, the log file ends at "PORT" or "PASV" - there's no record of ever receiving a "LIST" command. Just above that I can see the attempt to connect actively via the internal IP, which does indeed include a LIST command. My config file includes "PassivePorts 20001-26999", which are the port forwards I set up for the ftp server, and "Port 8085", which is also forwarded to the same machine. I also have a MasqueradeAddress set up to prevent it from reporting its internal IP, which was an earlier issue I had. I think what I'm asking is, is there another setting someplace I have to change to get this setup to work?

  • Uncovering Compiler Errors in ASP.NET MVC Views

    - by Ben Griswold
    ASPX and ASCX files are compiled on the fly when they are requested on the web server. This means it’s possible that you aren’t catching compile errors associated with your views when you build your ASP.NET MVC project in Visual Studio.  Unless you’re willing to click through your entire application, rendering each view looking for errors, you application is left a little vulnerable to user issues.  Fortunately, there’s a work around.  Open up your MVC project file in notepad or within the Visual Studio IDE by unloading the project and then editing the .csproj file (both actions are available by right-clicking on the Project Node in Solution Explorer.)  Notice the MvcBuildViews option.  It’s probably set to false.  Flip the value to true and you’ll magically start compiling your views when you build your application. <MvcBuildViews>false</MvcBuildViews> Taking this action will slow down your builds a bit, but if you’re a hack like me, it’ll probably save your day in the long run. Now you’re probably thinking, “Neat trick – how’s it work?”  Scroll down toward the bottom of your csproj file and you will notice the AfterBuild target triggers the AspNetCompiler action if the MvcBuildViews option is set to true.  <Target Name="AfterBuild" Condition="'$(MvcBuildViews)'=='true'">   <AspNetCompiler VirtualPath="temp"                   PhysicalPath="$(ProjectDir)\..\$(ProjectName)" /> </Target> Great. One more thing. Let’s say you don’t want to slow down all of your builds, but you absolutely want to know if there are any compiler issues with your views before you commit your code to version control or deploy or whatever.  Here’s what you can do – change the AfterBuild condition to run if your configuration is set to Release mode.  <Target Name="AfterBuild" Condition="'$(Configuration)'=='Release'">   <!– Always pre-compile ASPX and ASCX in release mode –>   <AspNetCompiler VirtualPath="temp"                   PhysicalPath="$(ProjectDir)\..\$(ProjectName)" /> </Target> Now your debug mode builds will continue to be as fast as ever and you can quickly validate your views by building in release mode when you so choose.  There’s one little catch – this setup won’t consider the MvcBuildViews option whatsoever! So if you decide to go with this configuration, you might want to add a comment near the MvcBuildViews option letting other developers know they can change the MvcBuildViews option as much as they’d like but it’s not going to affect the AfterBuild action.  Or don’t include the comment and let your team members figure it out for themselves…
