  • jQuery not working on Popup Window

    - by Seth Duncan
    I am using ASP.Net and jQuery + jQuery UI. Everything works fine with the jQuery on any other page, however when I create a popup window with window.open(...) jQuery seems to no longer function. I have all of the script files included on the Popup's Master page, so am not sure why it won't fire. Any Thoughts?

  • Android Custom PopWindow/Dialog

    - by Kilnr
    I'm trying to get a completely custom Dialog or PopupWindow, without any of the default Android UI controls (title, background, buttons, whatever). Is this possible at all? I've spent hours searching for this, but no luck... It seems like this should be easily possible, but I can't find it. Preferably this would be by inflating a View from XML, but at this point anything that would just work would be nice. Thanks.

  • SQL Server Constraints Across Tables

    - by chama
    I have a SQL Server database with an Apartment table (which has columns FloorNum and BuildingID) and an ApartmentBuilding table (with column NumFloors). Is there any way to set up a constraint (using the SQL Server UI) to check that Apartment.FloorNum is greater than ApartmentBuilding.NumFloors? I tried this: FloorNum > ApartmentBuilding.NumFloors but now I realize that I somehow have to join the columns on the BuildingID, but I have no idea how to do that within a constraint. Thanks for your help!

  • Configuration file reading. Best practice

    - by Andrew Florko
    Application stores configuration data in custom section of configuration file. This information is used all over the application. Nowadays I use helper static class to to provide access like this (some code omitted or simplified): [XmlRoot("webSiteSection")] public class WebSiteConfig : IConfigurationSectionHandler { public static WebSiteConfig Current { get { if (_current == null) _current = (WebSiteConfig) ConfigurationManager.GetSection("webSiteSection"); return _current; } } [XmlElement("section1")] public Section1 Section1 { get; set; } [XmlElement("section2")] public Section2 Section2 { get; set; } ... public object Create(object parent, object configContext, XmlNode section) { var serializer = new XmlSerializer(typeof(WebSiteConfig)); return serializer.Deserialize(new XmlNodeReader(section)); } } Then I use it like this <%: WebSiteConfig.Current.Section1.Value1 %> <%: WebSiteConfig.Current.Section1.Value2 %> What do you think of it? I find it usable because it keeps code simple, but also confused as IConfigurationSectionHandler is deprecated since .NET Framework 2.0

  • MVC pattern implementation. What is the n-relation between its components

    - by Srodriguez
    Dear all, I'm working in a C# project and we are , in order to get some unity across the different parts of our UI, trying to use the MVC pattern. The client is windows form based and I'm trying to create a simple MVC pattern implementation. It's been more challenging than expected, but I still have some questions regarding the MVC pattern. The problem comes mostly from the n-n relationships between its components: Here is what I've understood, but I'm not sure at all of it. Maybe someone can correct me? Model: can be shared among different Views. 1-n relationship between Model-View View: shows the state of the model. only one controller (can be shared among different views?). 1-1 relationship with the Model, 1-1 relationship with the controller Controller: handles the user actions on the view and updates the model. One controller can be shared among different views, a controller interacts only with one model? I'm not sure about the two last ones: Can a view have several controller? Or can a view share a controller with another view? Or is it only a 1:1 relationship? Can a controller handle several views? can it interact with several models? Also, I take advantage of this question to ask another MVC related question. I've suppressed all the synchronous calls between the different members of the MVC, making use of the events and delegates. One last call is still synchronous and is actually the most important one: The call between the view and the controller is still synchronous, as I need to know rather the controller has been able to handle the user's action or not. This is very bad as it means that I could block the UI thread (hence the client itself) while the controller is processing or doing some work. How can I avoid this? I can make use of the callback but then how do i know to which event the callback comes from? PS: I can't change the pattern at this stage, so please avoid answers of type "use MVP or MVVC, etc ;) Thanks!

  • Java Web Application on Tomcat - Displaying a File Uploaded by User

    - by walnutmon
    I need to display uploaded files on a web application, the flow is as follows User uploads file through web UI Validation on image Makes call to imageRepository.store( uploadedImage, user.getSite() ) The user wants the image displayed which adds <img src="${anUploadedImage.getUrl()}"/> but that is where I'm stuck, what can getUrl() do? The simple solution is to put it someplace and let Apache serve the file, but then I can't use the application to ensure that one user isn't modifying the URL to view other users files, which in this case is important

  • How can I tell if a given hWnd is still valid?

    - by Ian P
    Please forgive my ignorance, I'm completely new when it comes to winforms programming. I'm using a third-party class that spawns an instance of Internet Explorer. This class has a property, hWnd, that returns the hWnd of the process. Later on down the line, I may want to reuse the instance of the application if it still exists, so I need to tell my helper class to attach to it. Prior to doing that, I'd like to know if the given hWnd is still valid, otherwise I'll spawn another instance. How can I do this in C# & .NET 3.5? Thanks for the help and I apologize if my winforms nomenclature is all wacky.. haha Ian

  • How does multiple implementing multiple COM interfaces work in C++?

    - by Martin
    I am trying to understand this example code regarding Browser Helper Objects. Inside, the author implements a single class which exposes multiple interfaces (IObjectWithSite, IDispatch). His QueryInterface function performs the following: if(riid == IID_IUnknown) *ppv = static_cast<BHO*>(this); else if(riid == IID_IObjectWithSite) *ppv = static_cast<IObjectWithSite*>(this); else if (riid == IID_IDispatch) *ppv = static_cast<IDispatch*>(this); I have learned that from a C perspective, interface pointers are just pointers to VTables. So I take it to mean that C++ is capable of returning the VTable of any implemented interface using static_cast. Does this mean that a class constructed in this way has a bunch of VTables in memory (IObjectWithSite, IDispatch, etc)? What does C++ do with the name collisions on the different interfaces (they each have a QueryInterface, AddRef and Release function), can I implement different methods for each of these?

  • How To Get Type Info Without Using Generics?

    - by DaveDev
    Hi Guys I have an object obj that is passed into a helper method. public static MyTagGenerateTag<T>(this HtmlHelper htmlHelper, T obj /*, ... */) { Type t = typeof(T); foreach (PropertyInfo prop in t.GetProperties()) { object propValue = prop.GetValue(obj, null); string stringValue = propValue.ToString(); dictionary.Add(prop.Name, stringValue); } // implement GenerateTag } I've been told this is not a correct use of generics. Can somebody tell me if I can achieve the same result without specifying a generic type? If so, how? I would probably change the signature so it'd be like: public static MyTag GenerateTag(this HtmlHelper htmlHelper, object obj /*, ... */) { Type t = typeof(obj); // implement GenerateTag } but Type t = typeof(obj); is impossible. Any suggestions? Thanks Dave

  • How can I implement a site with ASP.NET MVC without using Visual Studio?

    - by Cheeso
    I have seen ASP.NET MVC Without Visual Studio, which asks, Is it possible to produce a website based on ASP.NET MVC, without using Visual Studio? And the accepted answer is, yes. Ok, next question: how? Here's an analogy. If I want to create an ASP.NET Webforms page, I load up my favorite text editor, create a file named Something.aspx. Then I insert into that file, some boilerplate: <%@ Page Language="C#" Debug="true" Trace="false" Src="Sourcefile.cs" Inherits="My.Namespace.ContentsPage" %> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Title goes here </title> <link rel="stylesheet" type="text/css" href="css/style.css"></link> <style type="text/css"> #elementid { font-size: 9pt; color: Navy; ... more css ... } </style> <script type="text/javascript" language='javascript'> // insert javascript here. </script> </head> <body> <asp:Literal Id='Holder' runat='server'/> <br/> <div id='msgs'></div> </body> </html> Then I also create the Sourcefile.cs file: namespace My.Namespace { using System; using System.Web; using System.Xml; // etc... public class ContentsPage : System.Web.UI.Page { protected System.Web.UI.WebControls.Literal Holder; void Page_Load(Object sender, EventArgs e) { // page load logic here } } } And that is a working ASPNET page, created in a text editor. Drop it into an IIS virtual directory, and it's working. What do I have to do, to make a basic, hello, World ASPNET MVC app, in a text editor? (without Visual Studio) Suppose I want a basic MVC app with a controller, one view, and a simple model. What files would I need to create, and what would go into them?

  • Export products and variants from MSSQL

    - by mickyjtwin
    I have a SQL DB that has a table of products, and another table which contains a list of the sku variants of each product if it has one. I want to export all the products and their SKU's into excel. At the moment, I have a helper SQL function which performs the subquery against a product_id and concatenates all the SKU's into a comma-delimited string, e.g: Product Code, Name, SKUs 111 P1 77, 22, 11 Is there an easier way to do this, so that each SKU is a row which the associated product code as well, i.e: Product Code, Name, SKUs 111 P1 77 111 P1 22 111 P1 11

  • JBoss classloading when 2 WARs have the same class

    - by Pacman
    I have a web applications A.war which has two servlets AServlet and BServlet. Both instantiate a helper class com.mycompany.Foo.class (this is my own class, not a third party library). Now I want to split the two servlets into two separate WARs: A.war will have only AServlet and a new B.war will have BServlet. AServlet will invoke BServlet via HTTP GET. Both WARs will have com.mycompany.Foo.class. I want to deploy both WARs on the same JBoss instance. The question is, will there be any classloading issues due to the same class being present in both WARs, and the WARs being deployed on the same JBoss instance?

  • Use javascript variables in Rails view helpers

    - by Horacio
    Using jqGrid I want to generate delete links for each row in the grid. The standard way to do this is to add the links in the gridComplete callback like shown below: gridComplete: function() { var ids = jQuery("#jobs_table").jqGrid('getDataIDs'); for(var i=0;i < ids.length;i++){ var cl = ids[i]; be = '<%= link_to(image_tag("delete.gif", :border=>0, :size=>"20x22", :alt => "delete"),· { :action => 'destroy', :id => 'cl', :method => :delete}, :class => 'ajax') -%>'; jQuery("#jobs_table").jqGrid('setRowData',ids[i],{workflow_state:be}); } }, Using getDataIDs I get a list of IDs that I can use to generate the delete links. The problem is that this is a javascript call that results in a javascript variable. The question is how can I use this variable "cl" inside rails link_to view helper?

    Has anyone taken the vmware certified professional exam? I was wondering if I can just take this class: http://mylearn1.vmware.com/mgrreg/courses.cfm?ui=www&a=one&id_subject=10103 or would I need to do additional studying on my own? I'm a developer with limited server experience. I'm aware of the technologies but haven't worked with them directly. Anyone that has taken the exam or has been in a similar situation, any insight would be appreciated.

  • How can I use SiteMap more efficiently?

    - by Bipul
    So, in our website we are using SiteMap. For each request we render some menu and to do that we do SiteMap.RootNode in the helper function. Now, when I have done the profiling of my website using dotTrace, I saw the get_RootNode() is taking lot's of time(around 70-75 millisecond). But we know that the SiteMap is static. So, I am thinking in somehow I will get the SiteMap.RootNode only once in Application_Start and will access that through out each request. So, my questions are, Is my approach correct? How should I do that? Or is there any efficient way that I can use SiteMap.RootNode Thanks.
