• Adding Street View controls (the two icons just above the +) to a Google Map (v3)

  - by AlexV

  It's probably something really simple, but I can't find it in the docs and I can't find a map with it to check it's source... I use version 3 of the API. I guess it's an something to add in myOptions? var latlng = new google.maps.LatLng(-34.397, 150.644); var myOptions = { zoom: 8, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP } map = new google.maps.Map(document.getElementById('map_canvas'), myOptions); Currently I only have dragging controls and the zoom pane controls. I would like to have the two Street View controls icons too. If you want full source, I'm using this example as a base (how would you add Street View controls to this example?).

• html5 video player with simplest controls (only play and paus)

  - by mathiregister

  hi guys, somehow there are really little tutorials out there for html5 video and audio playback. I simply want to embed video and audio files with customized controls. However the controls should be farely simple. I only need a play-button. If clicked, play gets replaced by pause. that's all! however i even don't know how to embed/display a video without "preload controls". Somehow if i only set (without preload controls) Firefox even don't shows anything. Chrome does show a black window. I would love to be able to use jquery to control the video play and pause button. Maybe you have some little start-approach for me! thank you very much!

• Displaying a collection of controls in a specific way in WPF

  - by Alvaro

  I have a collection of controls "MyCollection" wich changes in the Runtime. And I have to follow some constraints for that, for example: If my parameter "MyCollection.Count = 4" the property "NumberOfcolumns" will have the value 2, in order to create new Lines, and show the controls Two per Two. This is how I'm displaying my collection : <ItemsControl ItemsSource="{Binding MyCollection}" BorderThickness="0" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" > <ItemsControl.ItemsPanel> <ItemsPanelTemplate > <UniformGrid Columns="{Binding NumberOfColumns}" VerticalAlignment="Center" HorizontalAlignment="Center" Background="Transparent"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> The problem is that my controls have different sizes, and as In UniformGrids, Cells are uniform... My design is not really pretty, because I have little controls shown in big Cells !! Can someone help me to solve this problem ? NB: Please give me a detailled solution if possible, not something like : "Use WrapPanel..."

• iPhone 3rd Party Controls?

  - by Driss Zouak

  I was wondering if there are any 3rd party controls for use with the iPhone that are available, even better if usable from Interface Builder. From what I can gather, the answer is no. I come from a Microsoft .NET background where of course there are tons of controls available from 3rd parties. I'm curious if this is a general Mac development ecosystem fact, i.e. no 3rd party controls for sale, or just an iPhone one, or if I've just missed finding them.

• How to make all controls of a column the same width

  - by ant18

  Hi I need to know if there's any way of making all controls of a column the same width, and that all these controls are as wide as the cells that contain them. I added a demo on JSFiddle with the controls I'm using. I tried using size for the input texts and style="width:" for the selects , and even though I managed to make them the same width,(it doesn't seem to work in Chrome) it's kinda difficult , that's why I'd like to know if there is any more straightforward way to do the same thing Any ideas or insights?

• Zoom controls not showing when using a MapView with fill_parent

  - by Joe

  Hey everyone I am working on an applications and I am using the built in zoom controls. When using a specific size I can see the zoom controls. When using fill_parent the zoom controls are not visible. How it is setup is a mapview inside of a frame layout(also using fill parent for the height and width but with an offset down the screen. The only thing I can think of is the fill parent issue is with the framelayout and the zoom controls are off the screen. Sorry if this is confusing, I confused myself writing it. Thanks in advance

• Render multiple control collections in ASP.NET custom control

  - by Monty

  I've build a custom WebControl, which has the following structure: <gws:ModalBox ID="ModalBox1" HeaderText="Title" runat="server"> <Contents>(controls...)</Contents> <Footer>(controls...)</Footer> </gws:ModalBox> The control contains two ControlCollection properties, 'Contents' and 'Footer'. Never tried to build a control with multiple control collections, but solved it like this (simplified): [PersistChildren(false), ParseChildren(true)] public class ModalBox : WebControl { private ControlCollection _contents; private ControlCollection _footer; public ModalBox() : base() { this._contents = base.CreateControlCollection(); this._footer = base.CreateControlCollection(); } [PersistenceMode(PersistenceMode.InnerProperty)] public ControlCollection Contents { get { return this._contents; } } [PersistenceMode(PersistenceMode.InnerProperty)] public ControlCollection Footer { get { return this._footer; } } protected override void RenderContents(HtmlTextWriter output) { // Render content controls. foreach (Control control in this.Contents) { control.RenderControl(output); } // Render footer controls. foreach (Control control in this.Footer) { control.RenderControl(output); } } } However it seems to render properly, it doesn't work anymore if I add some asp.net labels and input controls inside the property. I'll get the HttpException: Unable to find control with id 'KeywordTextBox' that is associated with the Label 'KeywordLabel'. Somewhat understandable, because the label appears before the textbox in the controlcollection. However, with default asp.net controls it does work, so why doesn't this work? What am I doing wrong? Is it even possible to have two control collections in one control? Should I render it differently? Thanks for replies.

• How to cache dynamic javascript/jquery/ajax/json content with Akamai

  - by Starfs

  Trying to wrap my head around how things are cached on a CDN and it is new territory for me. In the document we received about sending in environment requests, it says "Dynamically-generated content will not benefit much from EdgeSuite". I feel like this is a simplified statement and there has to be a way to make it so you cache dynamically generated content if the tools are configured correctly. The site we are working with runs off a wordpress database, and uses javascript and ajax to build the pages, based on the json objects that php scripts have generated. The process - user's browser this URL, browser talks to edgesuite tools which will have cached certain pre-defined elements, and then requests from the host web server anything that is not cached, once edgesuite has compiled a combination of the two, it sends that information back to the browser. Can we not simply cache all json objects (and of course images, js, css) and therefore the web browser never has to hit the host server's database, at which point in essence, we have cached our dynamic content? Does anyone have any pointers on the most efficient configuration for this type of system -- Akamai/CDN -- to served javascript/ajax/json generated pages that ideally already hit pre-cached json data? Any and all feedback is welcome!

• Adding dynamic business logic/business process checks to a system

  - by Jordan Reiter

  I'm wondering if there is a good extant pattern (language here is Python/Django but also interested on the more abstract level) for creating a business logic layer that can be created without coding. For example, suppose that a house rental should only be available during a specific time. A coder might create the following class: from bizlogic import rules, LogicRule from orders.models import Order class BeachHouseAvailable(LogicRule): def check(self, reservation): house = reservation.house_reserved if not (house.earliest_available < reservation.starts < house.latest_available ) raise RuleViolationWhen("Beach house is available only between %s and %s" % (house.earliest_available, house.latest_available)) return True rules.add(Order, BeachHouseAvailable, name="BeachHouse Available") This is fine, but I don't want to have to code something like this each time a new rule is needed. I'd like to create something dynamic, ideally something that can be stored in a database. The thing is, it would have to be flexible enough to encompass a wide variety of rules: avoiding duplicates/overlaps (to continue the example "You already have a reservation for this time/location") logic rules ("You can't rent a house to yourself", "This house is in a different place from your chosen destination") sanity tests ("You've set a rental price that's 10x the normal rate. Are you sure this is the right price?" Things like that. Before I recreate the wheel, I'm wondering if there are already methods out there for doing something like this.

• BizTalk: Dynamic SMTP Port: Unknown Error Description

  - by Leonid Ganeline

  Today I investigated one strange error working with Dynamic SMTP Port.   Event Type: Error Event Source: BizTalk Server 2006 Event Category: BizTalk Server 2006 Event ID: 5754 Date: ******** Time: ********AM User: N/A Computer: ******** Description: A message sent to adapter "SMTP" on send port "*********" with URI "mailto:********.com" is suspended. Error details: Unknown Error Description  MessageId:  {********} InstanceID: {********}   My code was pretty simple and the source of the error was hidden somewhere inside it.   msg_MyMessage(SMTP.CC) = var_CC; msg_MyMessage(SMTP.From) = var_From; msg_MyMessage(SMTP.Subject) = var_Subject; msg_MyMessage(SMTP.EmailBodyText) = var_Message;    // #1    msg_MyMessage(SMTP.SMTPHost) = " localhost "; msg_MyMessage(SMTP.SMTPAuthenticate) = 0; When I added line #2, this frustrating error disappeared.    msg_MyMessage(SMTP.EmailBodyTextCharset) = "UTF-8"; // #2 Conclusion: If we use the SMTP.EmailBodyText property, we must set up the SMTP.EmailBodyTextCharset property. To me it looks like a bug in BizTalk. [Maybe it is "by design", but in this case give us a useful error text!!!] And don't ask me how much time I've spent with this investigation.

• Dynamic Layout in BI Publisher

  - by Manoj Madhusoodanan

  This blog tells about how to set dynamic layout of a BI Publisher report.Lets take a simple business scenario.If user wants to view the output in either PDF or EXCEL.Two ways we can achieve this.  1) If the output type is not a program parameter the we can choose the layout type at the time of submission in the SRS window. 2) If the report output type is a parameter we need to choose the layout at the time of submission of the request using FND_REQUEST.ADD_LAYOUT. Here I am discussing the second approach.Following components I have created for this scenario. 1) XXCUST - Sample Report : This program actually generates the XML data. It is linked with a RTF template.Note: At the time of creating this program you can uncheck Use in SRS to prevent users from submitting from SRS window.Because we are submitting this program from another concurrent program.Also is not required to add it to request group.2) XXCUST - Report Wrapper : This program calls XXCUST - Sample Report and exposed to user through SRS.3) SAMPLE_REPORT_WRAPPER : Executable which calls xxcust_sample_rep.main4) SAMPLE_REPORT_EXE : Executable which calls xxcust_sample_rep.report_main5) XXCUST - Sample Report Data Definition : Data Definition linked to XXCUST - Sample Report6) XXCUST - Sample Report Template : Template linked to XXCUST - Sample Report Data Definition 7) Package 8) RTF

• Changing the RSS and Dynamic Views layout when using Blogger as a Podcast index

  - by Stuart

  I'm trying to set up a podcast service at present. This is just a 'spare time' task - so I wanted a quick, easy way to do it. To get this working: I've ripped (with owner permission) some YouTube content across to MP3 and hosted this content on Azure Blob Storage. I've posted blog posts - with linked mp3 content - inside a Blogger website. I've registered the RSS feed with iTunes This all seems to be working OK - http://dotnetmobilepodcast.blogspot.co.uk/ However, when it comes to a couple of final touches, then I'm hitting problems. RSS I would like to add iTunes metadata to the RSS feed. However, I can't find any way to do this inside the Blogger system. To workaround this I've tried using FeedBurner with its StreamCast plugin. However, the output from FeedBurner doesn't seem to be accepted by iTunes - e.g. http://feeds.feedburner.com/MobileAppCSharpPodcasts leads to this very unhelpful 11111 message: Is there any other way I can get this iTunes metadata content into the Blogger RSS feed - e.g. maybe an alternative service or a Yahoo! Pipe? Showing the MP3 files in the Blog I'm trying to work out how to automatically display the linked enclosures inside the blog posts - do the blogger Dynamic Views don't seem to have any way of doing this? I've found the HTML in those views very difficult to follow. If necessary I can workaround this using manual entries into each blog post... but I'd prefer to do this programatically if I can.

• Fix a jQuery/HTML5 dynamic content issue by upgrading jQuery

  - by Steve Albers

  The default NuGet template for MVC3 pushes down jQuery 1.5.1.  You can upgrade to a new version (1.7.1 is current when this is written) to avoid a problem with the creation of “unknown” HTML5 tags in IE6-8: Take this sample HTML page using HTML5Shiv to provide support for new HTML5 tags in IE6 – IE8.  The page has a number of <article> tags that are backwards compatible in Internet Explorer 6-8 thanks to the HTML5Shiv. After the article elements there is a jQuery 1.5.1 script tag, and a ready() event handler that appends a footer element with a copyright to each of the article tags.  This appears correctly in IE9, but in older IE browsers the unknown tag problem reappears for the dynamic <footer> elements, even though we have the HTML5Shiv at the top of the page.  The copyright text sits outside of the two separate footer tags. To solve the issue upgrade your jQuery files to an up-to-date version.  For instance in Visual Studio 2010: In the Solution Explorer right click on References and choose Manage NuGet Packages. In the Manage NuGet Packages window select the jQuery item on the middle of the page and click the “Upgrade” button. You may need to upgrade your script src references to point at the new version. Using the updated jQuery library the incorrect tags should disappear and styles should work properly:   You can find more information about the issue on the jQuery Bug Tracker site.

• OpenGL lighting with dynamic geometry

  - by Tank

  I'm currently thinking hard about how to implement lighting in my game. The geometry is quite dynamic (fixed 3D grid with custom geometry in each cell) and needs some light to get more depth and in general look nicer. A scene in my game always contains sunlight and local light sources like lamps (point lights). One can move underground, so sunlight must be able to illuminate as far as it can get. Here's a render of a typical situation: The lamp is positioned behind the wall to the top, and in the hollow cube there's a hole in the back, so that light can shine through. (I don't want soft shadows, this is just for illustration) While spending the whole day searching through Google, I stumbled on some keywords like deferred rendering, forward rendering, ambient occlusion, screen space ambient occlusion etc. Some articles/tutorials even refer to "normal shading", but to be honest I don't really have an idea to even do simple shading. OpenGL of course has a fixed lighting pipeline with 8 possible light sources. However they just illuminate all vertices without checking for occluding geometry. I'd be very thankful if someone could give me some pointers into the right direction. I don't need complete solutions or similar, just good sources with information understandable for someone with nearly no lighting experience (preferably with OpenGL).

• implementing dynamic query handler on historical data

  - by user2390183

  EDIT : Refined question to focus on the core issue Context: I have historical data about property (house) sales collected from various sources in a centralized/cloud data source (assume info collection is handled by a third party) Planning to develop an application to query and retrieve data from this centralized data source Example Queries: Simple : for given XYZ post code, what is average house price for 3 bed room house? Complex: What is estimated price for an house at "DD,Some Street,XYZ Post Code" (worked out from average values of historic data filtered by various characteristics of the house: house post code, no of bed rooms, total area, and other deeper insights like house building type, year of built, features)? In addition to average price, the application should support other property info ** maximum, or minimum price..etc and trend (graph) on a selected property attribute over a period of time**. Hence, the queries should not enforce the search based on a primary key or few fixed fields In other words, queries can be What is the change in 3 Bed Room house price (irrespective of location) over last 30 days? What kind of properties we can get for X price (irrespective of location or house type) The challenge I have is identifying the domain (BI/ Data Analytical or DB Design or DB Query Interface or DW related or something else) this problem (dynamic query on historic data) belong to, so that I can do further exploration My findings so far I could be wrong on the following, so please correct me if you think so I briefly read about BI/Data Analytics - I think it is heavy weight solution for my problem and has scalability issues. DB Design - As I understand RDBMS works well if you know Data model at design time. I am expecting attributes about property or other entity (user) that am going to bring in, would evolve quickly. hence maintenance would be an issue. As I am going to have multiple users executing query at same time, performance would be a bottleneck Other options like Graph DB (http://www.tinkerpop.com/) seems to be bit complex (they are good. but using those tools meant for generic purpose, make me think like assembly programming to solve my problem ) BigData related solution are to analyse data from multiple unrelated domains So, Any suggestion on the space this problem fit in ? (Especially if you have design/implementation experience of back-end for property listing or similar portals)

• Saving State Dynamic UserControls...Help!

  - by Cognitronic

  I have page with a LinkButton on it that when clicked, I'd like to add a Usercontrol to the page. I need to be able to add/remove as many controls as the user would like. The Usercontrol consists of three dropdownlists. The first dropdownlist has it's auotpostback property set to true and hooks up the OnSelectedIndexChanged event that when fired will load the remaining two dropdownlists with the appropriate values. My problem is that no matter where I put the code in the host page, the usercontrol is not being loaded properly. I know I have to recreate the usercontrols on every postback and I've created a method that is being executed in the hosting pages OnPreInit method. I'm still getting the following error: The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases. Here is my code: Thank you!!!! bool createAgain = false; IList<FilterOptionsCollectionView> OptionControls { get { if (SessionManager.Current["controls"] != null) return (IList<FilterOptionsCollectionView>)SessionManager.Current["controls"]; else SessionManager.Current["controls"] = new List<FilterOptionsCollectionView>(); return (IList<FilterOptionsCollectionView>)SessionManager.Current["controls"]; } set { SessionManager.Current["controls"] = value; } } protected void Page_Load(object sender, EventArgs e) { Master.Page.Title = Title; LoadViewControls(Master.MainContent, Master.SideBar, Master.ToolBarContainer); } protected override void OnPreInit(EventArgs e) { base.OnPreInit(e); System.Web.UI.MasterPage m = Master; Control control = GetPostBackControl(this); if ((control != null && control.ClientID == (lbAddAndCondtion.ClientID) || createAgain)) { createAgain = true; CreateUserControl(control.ID); } } protected void AddAndConditionClicked(object o, EventArgs e) { var control = LoadControl("~/Views/FilterOptionsCollectionView.ascx"); OptionControls.Add((FilterOptionsCollectionView)control); control.ID = "options" + OptionControls.Count.ToString(); phConditions.Controls.Add(control); } public event EventHandler<Insight.Presenters.PageViewArg> OnLoadData; private Control FindControlRecursive(Control root, string id) { if (root.ID == id) { return root; } foreach (Control c in root.Controls) { Control t = FindControlRecursive(c, id); if (t != null) { return t; } } return null; } protected Control GetPostBackControl(System.Web.UI.Page page) { Control control = null; string ctrlname = Page.Request.Params["__EVENTTARGET"]; if (ctrlname != null && ctrlname != String.Empty) { control = FindControlRecursive(page, ctrlname.Split('$')[2]); } else { string ctrlStr = String.Empty; Control c = null; foreach (string ctl in Page.Request.Form) { if (ctl.EndsWith(".x") || ctl.EndsWith(".y")) { ctrlStr = ctl.Substring(0, ctl.Length - 2); c = page.FindControl(ctrlStr); } else { c = page.FindControl(ctl); } if (c is System.Web.UI.WebControls.CheckBox || c is System.Web.UI.WebControls.CheckBoxList) { control = c; break; } } } return control; } protected void CreateUserControl(string controlID) { try { if (createAgain && phConditions != null) { if (OptionControls.Count > 0) { phConditions.Controls.Clear(); foreach (var c in OptionControls) { phConditions.Controls.Add(c); } } } } catch (Exception ex) { throw ex; } } Here is the usercontrol's code: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="FilterOptionsCollectionView.ascx.cs" Inherits="Insight.Website.Views.FilterOptionsCollectionView" %> namespace Insight.Website.Views { [ViewStateModeById] public partial class FilterOptionsCollectionView : System.Web.UI.UserControl { protected void Page_Load(object sender, EventArgs e) { } protected override void OnInit(EventArgs e) { LoadColumns(); ddlColumns.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(ColumnsSelectedIndexChanged); base.OnInit(e); } protected void ColumnsSelectedIndexChanged(object o, EventArgs e) { LoadCriteria(); } public void LoadColumns() { ddlColumns.DataSource = User.GetItemSearchProperties(); ddlColumns.DataTextField = "SearchColumn"; ddlColumns.DataValueField = "CriteriaSearchControlType"; ddlColumns.DataBind(); LoadCriteria(); } private void LoadCriteria() { var controlType = User.GetItemSearchProperties()[ddlColumns.SelectedIndex].CriteriaSearchControlType; var ops = User.GetItemSearchProperties()[ddlColumns.SelectedIndex].ValidOperators; ddlOperators.DataSource = ops; ddlOperators.DataTextField = "key"; ddlOperators.DataValueField = "value"; ddlOperators.DataBind(); switch (controlType) { case ResourceStrings.ViewFilter_ControlTypes_DDL: criteriaDDL.Visible = true; criteriaText.Visible = false; var crit = User.GetItemSearchProperties()[ddlColumns.SelectedIndex].SearchCriteria; ddlCriteria.DataSource = crit; ddlCriteria.DataBind(); break; case ResourceStrings.ViewFilter_ControlTypes_Text: criteriaDDL.Visible = false; criteriaText.Visible = true; break; } } public event EventHandler OnColumnChanged; public ISearchCriterion FilterOptionsValues { get; set; } } }

• How dynamic can I make my LINQ To SQL Statements?

  - by mcass20

  I have the need to construct a LINQ To SQL statement at runtime based on input from a user and I can't seem to figure out how to dynamically build the WHERE clause. I have no problem with the following: string Filters = "<value>FOO</value>"; Where("FormattedMessage.Contains(@0)",Filters) But what I really need is to make the entire WHERE clause dynamic. This way I can add multiple conditions at runtime like this (rough idea): foreach (Filter filter in filterlist) { whereclause = whereclause + "&& formattedmessage.contains(filter)"; }

• Will an Nginx as reverse proxy for Apache help on dynamic content only

  - by Saif Bechan

  I am planning to move all my static content to a CDN so on my server I only have dynamic content left. I now have Nginx set up as reverse proxy to Apache. The static request that came in where directly delivered by Nginx without having to go to Apache. In this case Nginx handled a large portion of the request and I can clearly see the necessity of Nginx. Now that I moved all the static content to another domain, is there still a need to have nginx in front of Apache. Because now all the request are by default dynamic requests and all go to Apache. Are there any other benefits of having Nginx and Apache running for only dynamic content. My dynamic content is PHP/MySQL Edit: To be clear: I now have Nginx as a reverse proxy. It delivers static and dynamic content. But I am moving my static files to a CDN. Do I then still need Nginx on my domain.

• How to handle concurrency control in ASP.NET Dynamic Data?

  - by Andrew

  I've been quite impressed with dynamic data and how easy and quick it is to get a simple site up and running. I'm planning on using it for a simple internal HR admin site for registering people's skills/degrees/etc. I've been watching the intro videos at www.asp.net/dynamicdata and one thing they never mention is how to handle concurrency control. It seems that DD does not handle it right out of the box (unless there is some setting I haven't seen) as I manually generated a change conflict exception and the app failed without any user friendly message. Anybody know if DD handles it out of the box? Or do you have to somehow build it into the site?
