• Pull DIV from separate page and update DIV in current page

  - by brhea

  Hi everyone, I've got a simple one but haven't been able to find an example of a solution that fits exactly what I'm asking. Sorry in advance if this is a repeat. From my navigation menu, I want each link to reference a specific DIV in a separate page and then pull that DIV and replace the content in the current page. <ul> <li><a href="#">About</a></li> <li><a href="#">Contact</a></li> ..and so on </ul> Elsewhere in the page: <div id="displayContent">Content refreshes onClick. Previous content fades out, fresh content fades in.</div> Separate page (content.php): <div id="about">About content</div> <div id="contact">Contact content</div>

• WPF Prism deactivate ?

  - by 2Fast4YouBR

  Hi all, I have an problem and would like to know if it is common problem or jsut with me. I am using Wpf with Prism and Unity, all with the pattern MvvM. I am loading a viewModel that has a reference to a dropdown with few items, my idea is that each time that the user click in some place to open the view that has this dropdown is that the dropdown will be shown with diferent values. The problem is that I see is that after I show the view for the first time and after the first DEACTIVATE, when I try to load it again looks like it is already in the memory (was not deactivated/disposed), so as is already in memory, it not call the constructor again of the modelView and the dropdown is shown with tha same old values. public BranchSelectionViewModel(IUnityContainer unityContainer) { this.unityContainer = unityContainer; User user = this.unityContainer.Resolve<User>(); this.branches = new ObservableCollection<Department>(user.Departments .Where(department => department.DepartmentId != user.SelectedDepartment.DepartmentId)); }

• How to handle feedback from background threads if the user uses the back button?

  - by Janusz

  I have the following problem: I have an Activity where a user can start a web search showing a new activity to show a progress bar until the results are shown. Now the user can either wait for the results or maybe think about the search parameters, hit the back button and triggering a new search. The search is running in an Async Task and therefor still running if the user hits back. At the moment the thread finishes it calls some methods on the old activity causing the activity to show a dialog. This causes the system to crash because the dialog tries to show itself with a reference to an activity that is not longer present on the screen. How can I achieve a dialog that is only shown if the activity is still active?

• How do I setup a WCF Data Service with an ADO.NET Entity Entity Model in another assembly?

  - by lsb

  Hi! I have an ASP.NET 4.0 website that has an Entity Data Model hooked up to WCF Data Service. When the Service and Model are in the same assembly everything works. Unfortunately, when I move the Model to another "shared" assembly (and change the namespace) the service compiles but throws a 500 error when launched in a browser. The reason I want to have the Model in a common assembly (lets call it RiaTest.Shared) is that I want share common validation code between the client and service (by checking "Reuse types in referenced assemblies" in the Advanced tab of the Add Service Reference dialog). Anyway, I've spent a couple of hours on this to no avail so any help in the regard would be appreciated...

• Why isn't the eigenclass equivalent to self.class, when it looks so similar?

  - by The Wicked Flea

  I've missed the memo somewhere, and I hope you'll explain this to me. Why is the eigenclass of an object different from self.class? class Foo def initialize(symbol) eigenclass = class << self self end eigenclass.class_eval do attr_accessor symbol end end end My train of logic that equates the eigenclass with class.self is rather simple: class << self is a way of declaring class methods, rather than instance methods. It's a shortcut to def Foo.bar. So within the reference to the class object, returning self should be identical to self.class. This is because class << self would set self to Foo.class for definition of class methods/attributes. Am I just confused? Or, is this a sneaky trick of Ruby meta-programming?

• C# app that uses Excel Interop, easy switch between 2003 2007?

  - by user320781

  I have an app written that just does really basic I/O on a spreadsheet. Read in a bunch of cells, do some sorting, and dump the output back into another spreadsheet. Works great on my machine. I have Office 2003 installed. When it runs on someone elses machine with 2007, it bombs, presumably due to the different versions of the Interop assemblies. I was hoping someone knew a way to dynamically change which/where the assembly is loaded from depending on the office version (getting the office version is easy from the registry). Sifting thru the rest of the internet, i didnt see anything to indicate that was possible :( . I tried installing the 2007 PIAs, but when i try to add a reference, they dont show up and i have no idea where to browse for them (they arent in the c:\windows\assemblies\; maybe the install didnt work). Am I going to have to get a machine with 2007 installed to build on every time i need to make updates?

• Updating GUI Component from a different class C# WPF

  - by Boardy

  Hi all, I am trying to update a GUI component (DataGrid) in one class from a different class. I am using C# and WPF Forms. When I used the standard WF forms I could pass a reference to the GUI component as a parameter to the function that needed to do the work with the DataGrid. However, I do not know how I can do this in WPF. I have Class1 which has the GUI component and I need Class3 to run the function inside Class2 which will automatically update the GUI display of the Datagrid found in Class1. Any help with this would be much appreciated.

• How to return settings from an object

  - by Rockbot

  i have done something like this: myProject = settings: duration: 500 value: 'aValue' aFunction: -> myElement.fadeOut myProject.settings.duration This is just a sample but my project is like that. A lot of times i have to reference to the settings to get a certain value, and i always have to write myProject.settings.value, and it doesn´t look good. My question is, can I call a function that returns the wanted value? Something like this? aFunction -> myElement.fadeOut getSetting(duration) I tried with getSetting: (param) -> myProject.settings.param but failed? Why is that? Thank you!

• Can you use the same Enum in multiple entities in Linq-to-SQL?

  - by Mark

  In my persistence layer, I've declared a load of Enums to represent tables containing reference data (i.e. data never changes). In Linq2SQL, I am able to set the type of an entity property to an enum type and all is well, but as soon as I set a second entity's property to use the same enum type, the Code Generator (MSLinqToSQLGenerator) start generating an empty code file. I assume that MSLinqToSQLGenerator is quietly crashing. The question is why, and are there any work-arounds? Anyone else experienced this problem?

• OpToSoapDomComv.TRefCache.FNodes contains references to non-existing XMLNodes

  - by Bascy

  In our D2007 application we are using a Webservice, accessed with a THTTPRIO object. When the TDatamodule containing the THTTPRIO object is Destroyed an access violation occurs. This AV is raised when the TSoapDOMConvert is freed, which in turn executes: TRefCache(RefMap[0].Instance).Free calling destructor TRefCache.Destroy; begin FHREFs.Free; FMHREFs.Free; FNodes := nil; //Causes AV end; FNodes is a TInterfaceList containing one reference to IXMLNodes, but the object seems to have been freed before all this. Does anyone know this problem? How to solve it?

• PowerPoint API, how to change slide layout programmatically

  - by 112811688864492097861

  Hello, I'm working on PowerPoint Add-In and I was faced with trouble I couldn't solve myself. The point is I need to change the slide Layout programmaticaly with C# (the Add-In Express 2009 for Office and .NET is used). If the new layout is a predefined one everything is fine but I need to set a custom layout as a new one (without slide recreating). Unfortunately, I didn't find any information on how to do it, PowerPoint object model reference documentation didn't answer me as well. There is just the ability to create a new slide that uses custom layout. I've done an experiment seria and have ensured that the Slide object stayed being the same while I have been changing layout both predefined and custom ones. I don't want to create a new slide when I need just switch the layout. Is it possible at all? Please help me to find a way of doing it. Thanks in advance.

• waitin closes browsers for all projects that are building.

  - by Scooter

  I'm having an issue running WatiN under CruiseControl.net, where on a .forceclose, watin is closing all open browser instances. I have multiple projects running under cruisecontrol, and its not uncommon for some of those projects to be building and testing at the same time. There has been more than one occasion where watin will close the browser window for a different project, causing it to fail. In my local tests, creating my watin instance under a new process fixes this issue. But running under cruisecontrol, when doing this, I lose my IE object: Object reference not set to an instance of an object. Running CC.net as a service CC.Net server is Windows 2003 IE6 Any thoughts?

• Linking error in OMNeT++ using Boost serialization library

  - by astriffe

  I'm very new to OMNeT++ and I'd like to use the serialization-library contained in the boost framework. However, when trying to use it, I get quite many errors such as: Description Resource Path Location Type undefined reference to `boost::archive::archive_exception::~archive_exception()' OmCCN line 36, external location: /home/alexander/UniBE/BT/simulator/boost-compiledLibs /include/boost/serialization/throw_exception.hpp C/C++ Problem . I guess the problem is that I didn't yet link the compiled library in OMNeT. I've had a look at the makefile but any changes there are worthless since it is generated automatically by makemake. Furthermore, trying to access the menu item 'makemake' in project properties OMNeT++ IDE throws an error (The currently displayed page contains invalid values). Can anyone give me a hint concerning what the error could cause or how to link the compiled library correctly? Any hints are very appreciated! cheers alex

• C# - Common way to format listview controls on forms?

  - by John M

  In a C# Winform application (3.5) there are numerous forms each with different listview controls. While each listview control uses different datasets the basic formatting of each remains the same. Basic formatting takes this form: /* appearance */ this.lstA.View = View.Details; this.lstA.AllowColumnReorder = true; this.lstA.CheckBoxes = false; this.lstA.FullRowSelect = true; this.lstA.GridLines = false; this.lstA.Sorting = SortOrder.Ascending; What I would like to do is create a class that can be used to set the initial format of the listview. How do I pass the listview (by reference?) to the class so that the appearance properties can be set?

• Boost Shared Pointers and Memory Management

  - by Izza

  I began using boost rather recently and am impressed by the functionality and APIs provided. In using boost::shared_ptr, when I check the program with Valgrind, I found a considerable number of "Still reachable" memory leaks. As per the documentation of Valgrind, these are not a problem. However, since I used to use the standard C++ library only, I always made sure that any program written is completely free from memory leaks. My question is, are these memory leaks something to worry about? I tried using reset(), however it only decrements the reference count, doesn't deallocate memory. Can I safely ignore these, or any way to forcibly deallocate the memory allocated by boost::shared_ptr? Thank you.
