  • jQuery callbacks - short version

    - by Frankie
    I've dug the manual and tried extensivelly to drop the extra function(){...} call after the error and success to do it like mootools but to no good luck. Is there any way i can avoid the extra function in jQuery? function doFileDelete(ui) { $.ajax({ error: function() { doFileDeleteAnimation(ui, false) }, success: function() { doFileDeleteAnimation(ui, true) }, url: '/url-to-delete-file' }); } Thank you!

  • Visual Studio: Lost CD

    - by JamesBrownIsDead
    I have my original CD housing for my copy of Visual Studio 2008 Standard. Therefore I still have my key. I have trial versions of 2008 and 2010, and Express versions of both, but can't find a place to enter my CD key. What am I suppose to do? I lost my CD. Should I just call MSFT and ask them what to do?

  • WCF (REST) multiple host headers with one endpoint

    - by Maan
    I have an issue with a WCF REST service (.NET 4) which has multiple host headers, but one end point. The host headers are for example: xxx.yyy.net xxx.yyy.com Both host headers are configured in IIS over HTTPS and redirect to the same WCF service endpoint. I have an Error Handling behavior which logs some extra information in case of an error. The problem is that the logging behavior only works for one of both URLs. When I first call the .net URL, the logging is only working for requests on the .net URL. When I first call the .com URL (after a Worker Process recycle), it’s only working on requests on the .com URL. The configuration looks like this: <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> <services> <service name="XXX.RemoteHostService"> <endpoint address="" behaviorConfiguration="RemoteHostEndPointBehavior" binding="webHttpBinding" bindingConfiguration="HTTPSTransport" contract="XXX.IRemoteHostService" /> </service> </services> <extensions> <behaviorExtensions> <add name="errorHandling" type="XXX.ErrorHandling.ErrorHandlerBehavior, XXX.Services, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </behaviorExtensions> </extensions> <bindings> <webHttpBinding> <binding name="HTTPSTransport"> <security mode="Transport"> <transport clientCredentialType="None"/> </security> </binding> </webHttpBinding> </bindings> <behaviors> <endpointBehaviors> <behavior name="RemoteHostEndPointBehavior"> <webHttp /> <errorHandling /> </behavior> </endpointBehaviors> </behaviors> …. Should I configure multiple endpoints? Or in which way could I configure the WCF Service so the logging behavior is working for both URLs? I tried several things, also solutions mentioned earlier on StackOverflow. But no luck until now...

  • UpdatePanel on masterpage does postback on first button click

    - by gevjen
    I have an update panel on a masterpage and for reasons unbeknown to me our content placeholder is within the updatepanel. But when I click on a button on one of our pages that uses the masterpage the page postsback. If I then click the button for a second time it does not postback and does an ajax call. Im wondering why it does a postback the first time when I dont want it to. Below is how I have the updatepanel set up

Directory documents/ Extensions ['.pdf', '.doc', '.txt'] Format Document But when I call the filebrowser, it allows all file extensions to be uploaded. How can I restrict filebrowser to upload only certain filetypes that I want? Thanks everyone

  • Can Java Code tell if it is in an App Server?

    - by Grasper
    Is there something I can call from a POJO to see if the code is currently in an App Server or outside of an App Server? Something like this (In rough PseudoCode): System.getRunningEnvironment().equals(Environment.Glassfish) or System.getRunningEnvironment().equals(Environment.ApplicationServer) or System.getRunningEnvironment().equals(Environment.JavaSE)

  • How to produce precisely-timed tone and silence?

    - by Bob Denny
    I have a C# project that plays Morse code for RSS feeds. I write it using Managed DirectX, only to discover that Managed DirectX is old and deprecated. The task I have is to play pure sine wave bursts interspersed with silence periods (the code) which are precisely timed as to their duration. I need to be able to call a function which plays a pure tone for so many milliseconds, then Thread.Sleep() then play another, etc. At its fastest, the tones and spaces can be as short as 40ms. It's working quite well in Managed DirectX. To get the precisely timed tone I create 1 sec. of sine wave into a secondary buffer, then to play a tone of a certain duration I seek forward to within x milliseconds of the end of the buffer then play. I've tried System.Media.SoundPlayer. It's a loser because you have to Play(), Sleep(), then Stop() for arbitrary tone lengths. The result is a tone that is too long, variable by CPU load. It takes an indeterminate amount of time to actually stop the tone. I then embarked on a lengthy attempt to use NAudio 1.3. I ended up with a memory resident stream providing the tone data, and again seeking forward leaving the desired length of tone remaining in the stream, then playing. This worked OK on the DirectSoundOut class for a while (see below) but the WaveOut class quickly dies with an internal assert saying that buffers are still on the queue despite PlayerStopped = true. This is odd since I play to the end then put a wait of the same duration between the end of the tone and the start of the next. You'd think that 80ms after starting Play of a 40 ms tone that it wouldn't have buffers on the queue. DirectSoundOut works well for a while, but its problem is that for every tone burst Play() it spins off a separate thread. Eventually (5 min or so) it just stops working. You can see thread after thread after thread exiting in the Output window while running the project in VS2008 IDE. I don't create new objects during playing, I just Seek() the tone stream then call Play() over and over, so I don't think it's a problem with orphaned buffers/whatever piling up till it's choked. I'm out of patience on this one, so I'm asking in the hopes that someone here has faced a similar requirement and can steer me in a direction with a likely solution.

  • Best practice for DAO pattern ?

    - by Tony
    I've seen a lot of codes use a service-dao pattern , I don't know the origin of this pattern . It force the front layer call service , then delegates some of the service task to dao. I want to ask : Does DAO layer do purely data access related task ? What about exception encapsulation ? Is there other pattern can be used to replace this ?

  • problem with a join

    I have this code: int se = (int) settings.GruppoSegreteria; var acc = db.USR_Accounts.Where( p => p.ID_Gruppo == se); var segreterie = from s in db.USR_Utenti join h in acc on s.ID equals h.USR_UtentiReference select s; And this error: The type of one of the expressions in the join clause is incorrect. Type inference failed in the call to 'Join' I don't understand it. Can you help me? thanks

  • deleting an object

    - by Nima
    Hi, First, when you want to free the memory assigned to an object in C++, which one is preferred? Explicitly calling deconstructor or using delete? Object* object = new Object(...); ... delete object; OR object->~Object(); Second, does the delete operator call the deconstructor implicitly? Thanks,

  • .NET 2.0 Process Elevation for App Installation

    - by Brian Gillespie
    We have an application written in both C++ and .NET that installs for all users in the Program Files folder. This application downloads new versions of itself (as MSI installers) and spawns the new installer process to replace itself. The install process as it exists today: Copy an install manager app (C#, .NET 2.0) to the temp directory. Call this 'Manager' Manager is executed with elevated privs per this article. The original application exits. Manager spawns the MSI installer (with elevated privs, since the copy is elevated) Manager spawns the new version of the app. The bug: The newly installed app is running in an elevated state. This causes problems I won't enumerate here. Ideally, the launch of the newly installed app would be run with the permissions of the original user. I can't figure out how to demote the app back to being the standard user after elevation. An inelegant hack: (yeah, yeah, this whole process is inelegant anyway) Copy the install manager to the temp directory Run the install manager with standard user privs. Lets call this instance 'LowlyManager'. Original application exits. LowlyManager spawns the app again, this time with elevated privs. Let's name this instance 'UpperManagement' UpperManagement spawns the installer UpperManagement exits gracefully, returning the exit code of the installer. LowlyManager interprets the error code from UpperManagement, and spawns the newly installed application. This time as the original invoker. Is there a better way to do this? (I've left out a bunch of other details before and after these steps that make the process smoother for the user, but this should be enough to understand the core of the problem I'm trying to solve.) Other requirements: We can't install as a per-user app The user shouldn't be presented with an authentication dialog box if UAC would have simply asked "are you sure you want to allow this?". I think this might kill a solution using WindowsImpersonationContext, but I'm not sure. The system needs to work on XP, Vista, and Windows 7 (even if there is a separate process for XP).

  • What is the difference between moveBackward: and moveLeft: when using NSResponder -interpretKeyEvent

    - by nciagra
    I'm implementing a custom text box using -interpretKeyEvents: and am trying to figure out what the difference is between moveBackward: vs moveLeft: and moveForward: vs moveRight:. moveLeft: is bound to the left arrow and moveBackward: is bound to Ctrl + B. The documentation describes them almost identically and they seem to behave identically in practice. I'm assuming this is just a holdover from Vim? Does anyone know what the real difference is? Should moveBackward: just call my moveLeft: implementation? Thanks a lot, Nick

  • Me.Invoke in VB.NET doesn't actually "Invoke" - threads stall on Invoke statement

    - by rwmnau
    I've got the following code: Public Delegate Sub SetStatusBarTextDelegate(ByVal StatusText As String) Private Sub SetStatusBarText(ByVal StatusText As String) If Me.InvokeRequired Then Me.Invoke(New SetStatusBarTextDelegate(AddressOf SetStatusBarText), StatusText) Else Me.labelScanningProgress.Text = StatusText End If End Sub The problem is that, when I call the "SetStatusBarText" sub from another thread, InvokeRequired is True (as it should be), but then my threads stall on the Me.Invoke statement - pausing execution shows them all just sitting there, not actually invoking anything. Any thoughts about why the threads seem to be afraid of the Invoke?

  • Linux: How to find all serial devices (ttyS, ttyUSB, ..) without opening them?

    - by Thomas Tempelmann
    What is the proper way to get a list of all available serial ports/devices on a Linux system? In other words, when I iterate over all devices in /dev/, how do I tell which ones are serial ports in the classic way, i.e. those usually supporting baud rates and RTS/CTS flow control? The solution would be coded in C. I ask because I am using a 3rd party library that does this clearly wrong: It appears to only iterate over /dev/ttyS*. The problem is that there are, for instance, serial ports over USB (provided by USB-RS232 adapters), and those are listed under /dev/ttyUSB*. And reading the Serial-HOWTO at Linux.org, I get the idea that there'll be other name spaces as well, as time comes. So I need to find the official way to detect serial devices. Problem is that there appears none documented, or I can't find it. I imagine one way would be to open all files from /dev/tty* and call a specific ioctl() on them that is only available on serial devices. Would that be a good solution, though? Update hrickards suggested to look at the source for "setserial". Its code does exactly what I had in mind: First, it opens a device with: fd = open (path, O_RDWR | O_NONBLOCK) Then it invokes: ioctl (fd, TIOCGSERIAL, &serinfo) If that call returns no error, then it's a serial dev, apparently. I found similar code here, which suggested to also add the O_NOCTTY option. There is one problem with this approach, though: When I tested this code on BSD Unix (i.e. OSX), it worked as well, however serial devices that are provided thru Bluetooth cause the system (driver) to try to connect to the bluetooth device, which takes a while before it'll return with a timeout error. This is caused by just opening the device. And I can imagine that similar things can happen on Linux as well - ideally, I should not need to open the device to figure out its type. I wonder if there's also a way to invoke ioctl functions without an open, or open a device in a way that it does not cause connections to be made? Any ideas?

  • Pass data to a HttpModule

    - by Dejan
    I have a funny little situation on my hands. I have a httpModule on my hands that I have to feed with context relative data. That means that on the page I have to set something that the HttpModule can then react on. If possible I would like to avoid having call context data in the session. Any bright ideas out there. thx for the answer.

  • Creating a bitmask parameter for a function or method

    - by synic
    I noticed a lot of Android functions have a parameter that you can pass in that's a bitmask, for different options, like on PendingIntent, you can pass in things like you can call getActivity() with PendingIntent.FLAG_CANCEL_CURRENT|PendingIntent.FLAG_NO_CREATE. I'm wondering how I can create a function that has a parameter like this?

    Is it possible to convert floats from big to little endian? I have a value from a PowerPC(big endian)platform that I am send via TCP to a Windows process (little endian). This value is a float, but when I "memcpy" the value into a win32 float type and then call _byteswap_ulongon that value, I always get 0.0000? What am I doing wrong?

  • Passing a string representing my format specifier into stringWithFormat and seeing issues

    - by Jeff
    If I call "[NSString stringWithFormat:@"Testing \n %@",variableString]"; I get what I would expect, which is Testing, followed by a new line, then the contents of variableString. However, if i try NSString *testString = @"Testing \n %@"; //forgive shorthand here [NSString stringWithFormat,testString,variableString] the output actually literally writes \n to the screen instead of a newline. any workaround to this? seems odd to me
