  • How do I handle dojo datagrid cell updates so I can post them back automatically to the server?

    - by Raj
    I am using dojo datagrid to display my data. When the end user edit the cell values it should be updated in the server using ajax calls(when the focus goes out of the cell). Else, I should have a Edit & update/cancel buttons for each row to handle the same feature. But I don know how to place edit & update buttons inside the grid and capture their events. By default dojo updates only local the store value(client side). how can I save the updated cell values into the server? do we need to write any override methods to do so?? I am new to dojo. Any detailed explanation or sample codes would be much appreciated. Could anyone lend a hand to solve this issue?? Thank you Regards, Raj

  • Unit Testing in ASP.NET MVC: Minimising the number of asserts per test

    - by Neil Barnwell
    I'm trying out TDD on a greenfield hobby app in ASP.NET MVC, and have started to get test methods such as the following: [Test] public void Index_GetRequest_ShouldReturnPopulatedIndexViewModel() { var controller = new EmployeeController(); controller.EmployeeService = GetPrePopulatedEmployeeService(); var actionResult = (ViewResult)controller.Index(); var employeeIndexViewModel = (EmployeeIndexViewModel)actionResult.ViewData.Model; EmployeeDetailsViewModel employeeViewModel = employeeIndexViewModel.Items[0]; Assert.AreEqual(1, employeeViewModel.ID); Assert.AreEqual("Neil Barnwell", employeeViewModel.Name); Assert.AreEqual("ABC123", employeeViewModel.PayrollNumber); } Now I'm aware that ideally tests will only have one Assert.xxx() call, but does that mean I should refactor the above to separate tests with names such as: Index_GetRequest_ShouldReturnPopulatedIndexViewModelWithCorrectID Index_GetRequest_ShouldReturnPopulatedIndexViewModelWithCorrectName Index_GetRequest_ShouldReturnPopulatedIndexViewModelWithCorrectPayrollNumber ...where the majority of the test is duplicated code (which therefore is being tested more than once and violates the "keep tests fast" advice)? That seems to be taking it to the extreme to me, so if I'm right as I am, what is the real-world meaning of the "one assert per test" advice?

  • Getting black images with selenium.captureScreenshot

    - by Lidia
    I'm executing selenium tests with testng, that are started on a remote system with Selenium RC via hudson (with ssh connection). The remote system is windows xp with MKS Toolkit installed, hence ssh. Tests are NOT executed as a windows service. I've tried using both captureScreenshot and captureEntirePageScreenshot methods. The first one always produces a black image. The second one creates the correct screen shot but it only works on Firefox and our tests usually pass on Firefox and fail in other browsers, so it is crucial to capture screen shots for the other browsers (mainly IE and Safari). The tests are ran in parallel, with many browser windows open at the same time. I'm not certain if this is what's causing the problem. Any thoughts will be appreciated.

  • Passing Custom headers from .Net 1.1 client to a WCF service

    - by sreejith
    I have a simple wcf service which uses basicHttp binding, I want to pass few information from client to this service via custom SOAP header. My client is a .net application targetting .Net 1.1, using visual studio I have created the proxy( Added a new web reference pointing to my WCF service) I am able to call methods in the WCF service but not able to pass the data in message header. Tried to override "GetWebRequest" and added custom headers in the proxy but for some reason when I tried to access the header using "OperationContext.Current.IncomingMessageHeaders.FindHeader" it is not thier. Any idea how to solve this prob? This is how I added the headers protected override System.Net.WebRequest GetWebRequest(Uri uri) { HttpWebRequest request; request = (HttpWebRequest)base.GetWebRequest(uri); request.Headers.Add("tesData", "test"); return request; }

  • asp.net InsertCommand to return latest insert ID

    - by Stijn Van Loo
    Dear all, I'm unable to retrieve the latest inserted id from my SQL Server 2000 db using a typed dataset in asp.NET I have created a tableadapter and I ticked the "Refresh datatable" and "Generate Insert, Update and Delete statements". This auto-generates the Fill and GetData methods, and the Insert, Update, Select and Delete statements. I have tried every possible solution in this thread http://forums.asp.net/t/990365.aspx but I'm still unsuccesfull, it always returns 1(=number of affected rows). I do not want to create a seperate insert method as the auto-generated insertCommand perfectly suits my needs. As suggested in the thread above, I have tried to update the InsertCommand SQL syntax to add SELECT SCOPY_IDENTITY() or something similar, I have tried to add a parameter of type ReturnValue, but all I get is the number of affected rows. Does anyone has a different take on this? Thanks in advance! Stijn

  • Strange crashes on the iPad device with core graphics functions

    - by toastie
    I am getting a lot of strange EXC_BAD_ACCESS crashes on the iPad that only happen on the device and not in the simulator. I am assuming that they are somehow memory related, but I am not sure. They all happen with image context related functions. One strange example is using CGImageCreateWithImageInRect. For example, if i run through a bunch of UIImages and crop them with CGImageCreateWithImageInRect, it will always crash at specific arbitrary sizes. Like, if I crop them all to 200x200, it crashes out after processing 12 images. If i crop them to 210x210, it works no problem. The EXC_BAD_ACCESS happens inside of "memmove" called from "CGBlt_copyBytes". That is all the debugger shows me strangely enough. I can't see the callstack going up to any of my methods. All of this works fine in the simulator! I know this is all very vague, but if anyone has any ideas, they would be greatly appreciated.

As i'm reading papers i see that there are many attacks and researchers are trying to invent new methods for softwares to get more secure systems. this question can be a general including all types of attacks.There are many experienced programmers in SO, i just want to learn what are using to check your code against these attacks ? Is there any tools you use or you don't care ? For example i heard about,static,dynamic code analysis, fuzz testing. SQL injection attacks Cross Site Scripting Bufferoverflow attacks Logic errors Any kind of Malwares Covert Channels ... ... thanks

  • iPhone: Howto get notified when an UIView becomes visible

    - by arne_
    Is there a way to get a notification, a callback or some other means to call a method whenever a UIView becomes visible for the user, i.e. when a UIScrollview is the superview of some UIViews, and the ViewController of such a UIView shall get notified when its view is now visible to the user? I am aware of the possible, but not so elegant solution of checking to which position the ScrollView scrolled (via UIScrollViewDelegate-methods) and compute if either one of the subviews is visible... But I'm looking for a more universal way of doing this.

  • How to implement an override method in IronPython

    - by Adal
    I'm trying to implement a WPF control in IronPython and I'm having trouble implemented the override methods. The code below fails with this error: TypeError: expected int, got instancemethod. If I rename the VisualChildrenCount method, the exception is not raised anymore, but the control doesn't work. So how do I tell IronPython that the method is an override? class PaintCanvas(FrameworkElement): def __init__(self): self.__children = VisualCollection(self) dv = DrawingVisual() self.__children.Add(dv) # In C# this should be: protected override int VisualChildrenCount def VisualChildrenCount(self): return self.__children.Count # In C# this should be: protected override Visual GetVisualChild(int index) def GetVisualChild(self, index): return self.__children[index]

  • Issue with child of custom Decorator class in WPF

    - by galacticgrug
    I need a custom border that renders a little differently than a normal border. I made a class that inherited from Decorator as follows class BetterBorder : Decorator { protected override Size ArrangeOverride(Size arrangeSize) { return arrangeSize; } protected override void OnRender(DrawingContext dc) { //these values are calculated elsewhere dc.DrawGeometry(backgroundBrush, borderPen, pathGeometry); } } //Properties and helper methods below this All of this works fine until I try to add a child to the control, the control can be added but is not visible and seems to be moved off BetterBorders visible client area. If I inherit from Border everything works fine, what am I missing?

  • Drawbacks of WebFormsMVP?

    - by Tony_Henrich
    While ASP.NET MVC seems to be a viable technology praised by a lot of developers, I can't seem to find enough reasons to devote my energy and time for it. The main reason is that I don't find enough .NET jobs asking for it. Companies still use WebForms and it works just fine for them. I am not self employed where I get to choose the technology I like. I would rather use my time improve my skills in SilverLight, JQuery, Javascript, SQL, LINQ.. etc. Even Photoshop! So I got interested in webformsmvp.com. I get to still use WebForms and use better testing methods. Anyone who has experience with it can tell me what they didn't like about it?

  • textbox supplied route values with javaScript

    - by Maslow
    I've tried the bare method and the T4MVC method but so far both are routing me to the current URL instead of the default path with no arguments for the following action: public virtual ActionResult Index(byte? location, int? sublocation) { } So when I try Url.Action("Index","Locations", new {location="", system=""}) if I'm at a location already this method returns the path to where I'm already at instead of the default path with no arguments. As does the following method with T4MVC. <input type="button" value="Go" style="display:none" onclick="window.location='<%= Url.Action(MVC.Controller.Index()) %>/'+$('input#location').val()+'/'+$('input#sublocation').val()+'/';" /> How can I get the default route with no arguments?

  • How can you centre an image within the image control in SQL Server Reporting Services 2008?

    - by Keith
    I have got an image in an image control on a report in SSRS 2008. The image is coming from an external source, and varies in width. I would like to centre the image within the control, but the image control does not have an equivalent of the text box's TextAlign property to allow right/left/center alignment to be done automatically. I have seen methods to dynamically calculate the amount of left padding as a hack to solve this, http://blogs.msdn.com/chrishays/archive/2004/10/27/CenteredImages.aspx, but the solution gives an error in SSRS 2008, perhaps not surprising given the age of the article. Has anybody got a solution to this for SSRS 2008?

  • Program for HID USB Scale

    - by Alex
    Hi guys, I'm looking for a program that can read the weight on a USB scale, namely the Pelouze 10lb USB Portable Scale. I thought it would have a virtual COM port driver but instead, it uses HID drivers. I've been searching for a whole month for a program that can help me transfer the reading of the scale to Microsoft Excel. Can someone help me out or point me in the right direction? I am absolutely illiterate to programming. Much gratitude any help given.

  • C# TraceSource class in multithreaded application

    - by matti
    msdn: "Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe." it contains only instance methods. How should I use it in a way that all activity gets recorder by TextWriterTraceListener to a text file. Is one static member which all threads use (by calling) TraceEvent-method safe. (I've kind of asked this question in http://stackoverflow.com/questions/1901086/how-to-instantiate-c-tracesources-to-log-multithreaded-asp-net-2-0-web-applica, but I cannot just believe if somebody just says it's OK despite the documentation).

  • Has anybody use javafx on CDC J9?

    - by 4NDR01D3
    Is that possible?? I mean, I have an already working project that runs in windows mobile using the J9 virtual machine for CDC. My user interface there is using AWT and it works fine and it looks OK, but been honest it doesn't take real advantage of the devices were is running... So I start reading about JavaFX and that looks really cool, but all that I see about mobiles there is applied to CLDC, MIDP, etc. but my application is already running on CDC J9 and I can't change this cause I'm using a Derby database on it. So, my plan is to code the GUI again, but keeping the logic of the application. So do you guys think javafx is the way to go? or, am I wasting my time learning javafx for this project. Thanks in advance, Gustavo.

  • How to create a typed stack using Objective-C

    - by Xetius
    I can create a stack class quite easily, using push and pop accessor methods to an NSArray, however. I can make this generic to take any NSObject derived class, however, I want to store only a specific class in this stack. Ideally I want to create something similar to Java's typed lists (List or List) so that I can only store that type in the stack. I can create a different class for each (ProjectStack or ItemStack), but this will lead to a more complicated file structure. Is there a way to do this to restrict the type of class I can add to a container to a specific, configurable type?

  • 'Design By Contract' in C#

    - by IAmCodeMonkey
    I wanted to try a little design by contract in my latest C# application and wanted to have syntax akin to: public string Foo() { set { Assert.IsNotNull(value); Assert.IsTrue(value.Contains("bar")); _foo = value; } } I know I can get static methods like this from a unit test framework, but I wanted to know if something like this was already built-in to the language or if there was already some kind of framework floating around. I can write my own Assert functions, just don't want to reinvent the wheel.

  • PHP Scope Resolution Operator Question

    - by anthony
    I'm having trouble with the MyClass::function(); style of calling methods and can't figure out why. Here's an example (I'm using Kohana framework btw): class Test_Core { public $var1 = "lots of testing"; public function output() { $print_out = $this->var1; echo $print_out; } } I try to use the following to call it, but it returns $var1 as undefined: Test::output() However, this works fine: $test = new Test(); $test->output(); I generally use this style of calling objects as opposed to the "new Class" style, but I can't figure out why it doesn't want to work.

  • How to access a flash object embedded via swfobject's embedSWF?

    - by Andree
    Hi there, I have to call an ActionScript method via Javascript, but I have a problem accessing the flash object itself. I embed the flash file via the help of swfobject. Previously, when I use the static publishing approach, I could easily get the flash object by calling these methods: swfobject.registerObject("flash_object", "9", "expressInstall.swf"); var flash_object = swfobject.getObjectById("flash_object"); For some technical reasons, now I have to use the dynamic publishing approach (using swfobject.embedSWF). But, as mentioned in the documentation, the method getObjectById can only be used if you use static publishing approach. Now, how can I access the flash object? Cheers, Andree

  • How do I close a database connection in a WCF service?

    - by Dan
    I have been unable to find any documentation on properly closing database connections in WCF service operations. I have a service that returns a streamed response through the following method. public virtual Message GetData() { string sqlString = BuildSqlString(); SqlConnection conn = Utils.GetConnection(); SqlCommand cmd = new SqlCommand(sqlString, conn); XmlReader xr = cmd.ExecuteXmlReader(); Message msg = Message.CreateMessage( OperationContext.Current.IncomingMessageVersion, GetResponseAction(), xr); return msg; } I cannot close the connection within the method or the streaming of the response message will be terminated. Since control returns to the WCF system after the completion of that method, I don't know how I can close that connection afterwards. Any suggestions or pointers to additional documentation would be appreciated. Dan

  • Lighttpd not cleanly restarting (address already in use)

    - by NilObject
    When doing a dist-upgrade recently, my lighttpd-1.4.19 install on Ubuntu 8.0.4 has begun failing to restart or reload properly with the /etc/init.d/lighttpd restart command. ~$ sudo /etc/init.d/lighttpd restart * Stopping web server lighttpd ...done. * Starting web server lighttpd 2009-06-13 04:06:36: (network.c.300) can't bind to port: 80 Address already in use ...fail! The same error occurs when I do a reload. The way I get around it is to kill lighttpd and then issue the start command, but it seems like I shouldn't have to do that :) I've looked at my config files, and can't spot any immediate errors.
