  • WPF - Dynamic tooltip

    - by Al Mackenzie
    I have a class ToolTipProvider which has a method string GetToolTip(UIElement element) which will return a specific tooltip for the UIElement specified, based on various factors including properties of the UIElement itself and also looking up into documentation which can be changed dynamically. It will also probably run in a thread so when the form first fires up the tooltips will be something like the visual studio 'Document cache is still being constructed', then populated in the background. I want to allow this to be used in any wpf form with the minimum effort for the developer. Essentially I want to insert an ObjectDataProvider resource into the Window.Resources to wrap my ToolTipProvider object, then I think I need to create a tooltip (called e.g. MyToolTipProvider) in the resources which references that ObjectDataProvider, then on any element which requires this tooltip functionality it would just be a case of ToolTip="{StaticResource MyToolTipProvider}" however I can't work out a) how to bind the actual elemnt itself to the MethodParameters of the objectdataprovider, or b) how to force it to call the method each time the tooltip is opened. Any ideas/pointers on the general pattern I need? Not looking for complete solution, just any ideas from those more experienced

  • Dynamic ASP.NET controls using Infragistics

    - by Emil D
    So, in my asp.net webapp I need to dynamically load a custom control, based on the selected value of a dropdown list.That seems to work at first glance, but for some reason all infragistics controls that I have in my custom control appear, but won't work.I get a "Can't init [controlname]" warning in my browser.If I declare my custom control statically, this problem doesn't apprear Here's my code: Markup: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="GenericReportGUI.ascx.cs" Inherits="GenericReportGUI" %> <%@ Register assembly="Infragistics35.WebUI.Misc.v8.3, Version=8.3.20083.1009,Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" namespace="Infragistics.WebUI.Misc" tagprefix="igmisc" %> <asp:UpdatePanel ID="myUpdatePanel" runat="server" UpdateMode="Conditional"> <ContentTemplate> <igmisc:WebPanel ID="WebPanel1" runat="server"> <Template> <div> <asp:PlaceHolder ID="Placeholder" runat="server"> </asp:PlaceHolder> </div> </Template> </igmisc:WebPanel> </ContentTemplate> </asp:UpdatePanel> Code-behind: public partial class GenericReportGUI : System.Web.UI.UserControl { protected void Page_Load(object sender, EventArgs e) { } protected override void OnPreRender( EventArgs e ) { base.OnPreRender(e); loadCustomControl(); } protected void loadCustomControl() { Placeholder.Controls.Clear(); string controlPath = getPath(); //getPath() returns the path to the .ascx file we need to load, based on the selected value of a dropdownlist try { Control newControl = LoadControl( controlPath ); Placeholder.Controls.Add( newControl ); } catch { //if the desired control cannot be loaded, display nothing } myUpdatePanel.Update();//Update the UpdatePanel that contains the custom control } } I'm a total noob when it comes to asp.net, so any help with this issue would be greatly appreciated.

  • IIS7 URL Rewrite with dynamic subdomains.

    - by arri.me
    My goal is to implement the following scheme using the subdomain and path as attributes: Use a wildcard DNS entry that routes any subdomain to the root site: Example: *.example.com ex: http://xyz.example.com to http://example.com Next I want to rewrite the requests to point to a specific page, passing both the subdomain and the request path as attributes. Example: http://xyz123.example.com/images/header.jpg to http://example.com/get.aspx?id=xyz123&path=/images/header.jpg I've seen several questions on here regarding similar goals, but not quite the same. I'm new to using rewrite rules, so any help is appreciated. I will update this as I make progress.

  • jquery Fullcalendar : dynamic events function asp.net mvc

    - by Eran
    Hi, I'm integrating Fullcalendar into my app. Consider a manager interface where he can select an employee and then view this employee's calendar. Now basically I'm using the following jquery code in my view: <script type="text/javascript"> $(document).ready(function() { $("#calendar").fullCalendar({ defaultView: 'agendaWeek', isRTL: true, axisFormat: 'HH:mm', editable: true, events: "/Scheduler/CalendarData" }); }); </script> Now I would like to have the controller function assigned to the events to retrieve the specific user selected by the manager: events: "/Scheduler/CalendarData/<current_user_name> Is there any way to retrieve the selected employee user name from the view (or rather pass it to the view from the controler) and then pass it onto the bound events function? I hope I was clear enough... Thanks in Advance, Eran

  • GWT Dynamic loading using GWT.create() with String literals instead of Class literals

    - by Sathish
    GWT.create() is the reflection equivalent in GWT, But it take only class literals, not fully qualified String for the Class name. How do i dynamically create classes with Strings using GWT.create()? Its not possible according to many GWT forum posts but how is it being done in frameworks like Rocket-GWT (http://code.google.com/p/rocket-gwt/wiki/Ioc) and Gwittir (http://code.google.com/p/gwittir/wiki/Introspection)

  • Memory management / ownership question?

    - by fuzzygoat
    Do I have this right ... // Reactor.h @property(nonatomic, retain) NSMutableArray *reactorCore; // Reactor.m [self setReactorCore:[NSKeyedUnarchiver unarchiveObjectWithFile:[self dataFilePath]]]; ... -(void)dealloc { [reactorCore release]; [super dealloc]; } I am pretty sure I am doing this right (but just wanted to check). By my way of thinking NSKeyedUnarchiver returns an object it owns, I am then taking ownership via the @property, later I release reactorCore and all is good?

  • Load PDF from Memory ASP.Net

    - by Sandhurst
    I am using ITextSharp to generate pdf on the fly and then saving it to disk and display it using Frame. The Frame has an attribute called src where I pass the generated file name.

  • dynamic insert php mysql and preformance

    - by Ross
    I have a folder/array of images, it may be 1, maximum of 12. What I need to do is dynamically add them so the images are added to an images table. At the moment I have $directory = "portfolio_images/$id/Thumbs/"; $images = glob("" . $directory . "*.jpg"); for ( $i= 0; $i <= count($images); $i += 1) { mysql_query("INSERT INTO project_images (image_name, project_id)VALUES ('$images[0]', '$id')") or die(mysql_error()); } this is fine but it does not feel right, how is this for performance? Is there a better way? The maximum number of images is only ever going to be 12. Thanks, Ross

  • Visual Studio 2008 - App_webreferences and dynamic urls

    - by Patrick Hempton
    When you add a web service reference in VS 2008 Web site project, you get a new folder in App_webreferences. This contains a disco,wsdl and discomap file. Additionally, you get a key/value pair in the web.config which contains the endpoint URL. Within the disco,wsdl and discomap files, the URL is strewn about leaving many places to change the url as we move from dev/test/stage/production. Why is it that when I change the URL in the web.config and perform an update on the web reference, the old URL remains in all three of those files? Why does it not get updated? Has anyone figured out how to manage this? Any insight is appreciated.

  • htaccess mask dynamic url with a static url

    - by Enkay
    I'm trying to do something with .htaccess that I'm not sure can be done. First thing I did is hide the .php extensions using the following code: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^(.*)$ $1.php Works great. Now what I'm trying to do and can't seem to figure out is the following: When a user types "mywebsite.com/products?id=12345" into the browser address bar, I want the server to serve the right product page according to the ID but display it in the address bar as "mywebsite.com/product" no matter what the product ID is. Is this possible to do? If yes how? Thanks

  • Using an existing IQueryable to create a new dynamic IQueryable

    - by dnoxs
    I have a query as follows: var query = from x in context.Employees where (x.Salary > 0 && x.DeptId == 5) || x.DeptId == 2 order by x.Surname select x; The above is the original query and returns let's say 1000 employee entities. I would now like to use the first query to deconstruct it and recreate a new query that would look like this: var query = from x in context.Employees where ((x.Salary > 0 && x.DeptId == 5) || x.DeptId == 2) && (x,i) i % 10 == 0 order by x.Surname select x.Surname; This query would return 100 surnames. The syntax is probably incorrect, but what I need to do is attach an additional where clause and modify the select to a single field. I've been looking into the ExpressionVisitor but I'm not entirely sure how to create a new query based on an existing query. Any guidance would be appreciated. Thanks you.

  • dynamic layout change during runtime

    - by Nils
    Hello, for an application I need to place some objects at the exact position that I want to have them and therefore I need to use AbsoluteLayout this time. I want to add buttons dynamically exactly like in the following XML - but during runtime. <AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Button android:id="@+id/backbutton" android:text="TEST123" android:layout_x="120px" android:layout_y="120px" android:layout_width="100px" android:layout_height="100px" /> </AbsoluteLayout> How can I archive this? I tried it with the following code to add a button, but I haven't found a function so far to set layout_x and layout_y. How can I do this? Thanks. AbsoluteLayout al = new AbsoluteLayout(this); Button t = new Button(this); t.setHeight(300); t.setWidth(300); t.setText("TEST123"); // x y ??? setContentView(al);

What's going wrong here?

  • Dynamic fields with Thinking Sphinx

    - by Ola Karlsson
    Hi! I'm building an application where I have products and categories. Category has_many properties and each property has a list of possible values. After a category is set to the product all properties show up in the form and the user can set that property to one of the properties possible values. My question is: Is it possible for Thinking Sphinx to filter the products through a property and property value ex: :with => {:property_id => property_value} If it's possible, what is the best way to implement this? If not is there any other library out there to solve this problem? Thanks / Ola

    - by michael
    Hi, I create a TableLayout which has 3 equally-wide columns (I put 'stretchColumns="*" in my TableLayout which has 3 TextViews). See below: But my questions is why I set one of the TextView to 'visibility' to Gone in my java code, the TableLayout does not re-size to 2 qually-wide columns which fit the whole screen. I have even call 'tableLayout.requestLayout()' after i set the visibility to Gone.' How can I achieve what I want? Thank you. <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/textpanel" android:stretchColumns="*"> <TableRow android:layout_width="fill_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/text1" android:layout_width="fill_parent" android:layout_height="wrap_content"/> <TextView android:id="@+id/text2" android:layout_width="fill_parent" android:layout_height="wrap_content"/> <TextView android:id="@+id/text3" android:layout_width="fill_parent" android:layout_height="wrap_content"/> </TableRow> </TableLayout>

  • Powerbuilder Dynamic Array Manipulation

    - by TomatoSandwich
    string array[] long lBound, uBound lBound = LowerBound(array[]) // = 1, empty array value uBound = UpperBound(array[]) // = 0, empty array value array[1] = 'Item 1' array[2] = 'Item 2' array[3] = 'Item 3' lBound = LowerBound(array[]) // = 1 uBound = UpperBound(array[]) // = 3 array[3] = '' //removing item 3 lBound = LowerBound(array[]) // = 1, still uBound = UpperBound(array[]) // = 3, still (but array[3] is nulled? I think the line 'array[3]' is wrong, but I think I've read that this should remove the array cell. What would be the right way to remove an array cell? Does it depend on object type? (String vs Number vs Object) Or Can one manipulate the UpperBound value to make it work? i.e. after removing Item 3, I want the UpperBound, or arraylength, to be 2, since this is logically correct.

  • ASP.NET GridView - Editing Dynamic Template Columns

    - by user208662
    Hello, I have created a GridView whose columns are dynamically created based on my data source. I have implemented these columns by using the approach described here.Those columns display properly on the initial load. However, I need to implement commanding so that a user can edit / delete a row in the GridView. At this point, I have implemented commanding as I would with a normal GridView. I have a TemplateField with an ItemTemplate that has LinkButton elements for edit and delete. The CommandName for each LinkButton is set to either Edit or Delete respectively. Oddly, when a user clicks either the Edit or Delete link, the data in the GridView disappears. However, I have verified that I am in fact re-binding the data when one of these LinkButton elements is selected. Can anyone provide some suggestions as to what the cause could be? Thank you!
