  • Different EF Property DataType than Storage Layer Possible?

    - by dj_kyron
    Hi, I am putting together a WCF Data Service for PatientEntities using Entity Framework. My solution needs to address these requirements: Property DateOfBirth of entity Patient is stored in SQL Server as string. It would be ideal if the entity class did not also use the "string" type but rather a DateTime type. (I would expect this to be possible since we're abstracting away from the storage layer). Where could a conversion mechanism be put in place that would convert to and from DateTime/string so that the entity and SQL Server are in sync?. I cannot change the storage layer's structure, so I have to work around it. WCF Data Services (Read-only, so no need for saving changes) need to be used since clients will be able to use LINQ expressions to consume the service. They can generate results based on any given query scenario they need and not be constrained by a single method such as GetPatient(int ID). I've tried to use DTOs, but run into problem of mapping the ObjectContext to a DTO, I don't think that is theoretically possible...or too complicated if it is. I've tried to use Self Tracking Entities but they require the metadata from the .edmx file if I'm correct, and this isn't allowing a different property data type. I also want to add customizations to my Entity getter methods so that a property "MRN" of type "string" needs to have .Replace("MR~", string.Empty) performed before it is returned. I can add this to the getter methods but the problem with that is Entity Framework will overwrite that next time it refreshes the entity classes. Is there a permanent place I can put these? Should I use POCO instead? How would that work with WCF Data Services? Where would the service grab the metadata?

  • Beginner Question on traversing a EF4 model

    - by user564577
    I have a basic EF4 model with two entities. I'm using Self Tracking Entities Client has ClientAddresses relationship on clientkey = clientkey. (1 to many) How do i get a list/collection of client entities (STE) and their addresses (STE) but only ones where they live in a particular state or some such filter on the address??? This seems to filter and bring back clients but doesnt bring back addresses. var j = from client in context.Clients where client.ClientAddresses.All(c => c.ZIP == "80923") select client; I cant get this to create the Addresses because ClientAddresses is IEnumerable and it needs a TrackableCollection var query = from t1 in context.Clients join t2 in context.ClientAddresses on t1.ClientKey equals t2.ClientKey where t2.ZIP == "80923" select new Client { FirstName = t1.FirstName, LastName = t1.LastName, IsEnabled = t1.IsEnabled, ClientKey = t1.ClientKey, ChangeUser = t1.ChangeUser, ChangeDate = t1.ChangeDate, ClientAddresses = from a in t1.ClientAddresses select new ClientAddress { AddressKey = a.AddressKey, AddressLine1 = a.AddressLine1, AddressLine2 = a.AddressLine2, AddressTypeCode = a.AddressTypeCode, City = a.City, ClientKey = a.ClientKey, State = a.State, ZIP = a.ZIP } }; Any pointers would be appreciated. Thanks Edit: This seems to work.... var j = from client in context.Clients.Include("ClientAddresses") where client.ClientAddresses.Any(c => c.ZIP == "80923") select client;

  • Dynamically pixelate an html image element

    - by Chris Armstrong
    I'm to take an image on a webpage, and then use javascript (or whatever would be best suited) to dynamically 'pixelate' it (e.g. into 20px squares). Then, as the user scrolls down the page, I need the image to gradually increase in resolution, till it is no longer pixelated. Any ideas how I could go about doing this? I realise I could use php to resize an image and several times and just switch out the image, but that would require loading several extra images. Also, I know I could probably do the effect with flash & pixelbender, but I want to achieve it within the limitations of HTML5, CSS & Javascript if possible. Appreciate any thoughts!

  • How come JFrame window size in Java does not produce the size of window specified?

    - by typoknig
    Hi all, I am just messing around trying to make a game right now, but I have had this problem before too. When I specify a specific window size (1024 x 768 for instance) the window produced is just a little larger than what I specified. Very annoying. Is there a reason for this? How do I correct it so the window created is actually the size I want instead of being just a little bit bigger? Up till now I have always just gone back and manually adjusted the size a few pixels at a time until I got the result I wanted, but that is getting old. If there was even a formula I could use that would tell me how many pixels I needed to add/subtract from my my variable that would be excellent! P.S. I don't know if my OS could be a factor in this, but I am using W7X64. private int windowWidth = 1024; private int windowHeight = 768; public SomeWindow() { this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setSize(windowWidth, windowHeight); this.setResizable(false); this.setLocation(0,0); this.setVisible(true); }

  • How to access Google Maps API v3 marker's DIV and it's pixel position?

    - by Ray Yun
    Instead of google maps api's default info window, I'm going to use other jquery tooltip plugin over marker. So I need to get marker's DIV and its pixel position. But couldn't get it because there are no id or class for certain marker. Only I can access map canvas div from marker object and undocumented pixelBounds object. How can I access marker's DIV? Where can I get DIV's pixel position? Can I convert lat-lng position to pixel values?

  • What is the pixel clock setting on my monitor actually doing?

    - by codecowboy
    I am experiencing display interference on a dell 24" flat panel monitor.I find that if I adjust the pixel clock settings up or down in the monitor's on-screen menus, the interference goes away for a while. The monitor is attached to a Macbook Pro using a mini display to VGA adapter. I have found that in a different house, I get the interference problem less so it might be related to electricity supply or possibly even ethernet powerline (total guess). What does the pixel clock setting actually do and does this behaviour point to a likely cause of the interference?

  • Why does my MacBook Pro trackpad sometimes set its tracking speed to slow, all by itself?

    - by Paul D. Waite
    Every now and then, the trackpad on my MacBook Pro will seem to set its own tracking speed to slow. I’ll notice that the cursor is moving slowly, and when I check in System Preferences, the tracking speed is indeed at slow, even though I never set it to slow myself. This might happen before/after switching into a VMWare virtual machine, but I’m not sure. It doesn’t seem to happen on startup or anything, just during use. Anyone else seen this?

  • Will Tracking Subdomains as Single Entity with Google Analytics Help SEO? [closed]

    - by Sam Gridley
    Possible Duplicate: Does Google Analytics data affect SEO? We have two subdomains, one for our blog and one for our ecommerce store. The blog serves to bring traffic and the store is how we monetize the site. We have them designed to appear as one large site, but I know google sees them as two sites. Here is how the subdomains look: www.example.com (store) blog.example.com (blog) I believe I can configure analytics to use subdomain tracking as explained here: http://support.google.com/googleanalytics/bin/answer.py?hl=en&answer=55524 But my question is whether this will cause google to see our 2 subdomains as one larger domain for SEO purposes. In other words, is there any relationship to how you configure google analytics and how google indexes and ranks your website(s) and pages? Is there anything I need to do in anaytics or webmaster tools to make google aware that these two subdomains work together as one website? Thanks! Sam

  • Dashboard to aggregate Google Analytics, Facebook, YouTube etc tracking data?

    - by Richard
    I'd like to see as much tracking data as possible about my online presence, in one single dashboard - so views/conversions from Google Analytics data, the performance of my Facebook campaigns via the Insights API, views/clicks from my YouTube campaigns, etc. This could be as simple as a graph with time on the x-axis, and key indicators from each source on the y-axis (conversions from Analytics, likes on Facebook, views on YouTube, etc). The idea is that I can see customer engagement with each source, over time. I can write my own such dashboard easily enough, but I wondered if there was something off-the-shelf that already did this. Apologies if this isn't the right forum for such a question - would appreciate tips for the best place to ask.

  • Tracking logged in vs. non-logged in users in Google Analytics

    - by Justin
    I am building a social media site that is similar is structure to twitter and facebook.com where unauthenticated users who go to https://mysite.com will see a login + sign-up page, and authenticated users who go to https://mysite.com will see their timeline. My question is, what is the best practice (using Google Analytics) for tracking these two different types of users who are viewing completely different content but are visiting the same URL. I tried searching the Google Analytics docs but couldn't find what they suggested for this scenario. Perhaps I just don't know what keywords to search for. Thanks in advance for any help.

  • possible to have a background color transition from color A to color B without repeating a pixel sti

    - by Andrew Heath
    For things like menubars and headers, a background color is nice. But a background color that gracefully transitions from say Blue to White is even nicer. I know this can be done by making a 1-pixel wide, X-pixel tall image file containing the desired fade and repeating it across the div, but does CSS have native support to just define colors and be done with it? Can any other language handle this?

  • Is this technique for stat tracking without a database workable?

    - by baptzmoffire
    If I wanted to create a chess game, for iOS, that tracked both player moves (for retracing the progression of a game and for player stats), what would be the simplest route to take? To clarify, I want to track not only the moves a player has made in a particular game, but how often that player has made that move in past games. For example I want to be able to track: How many times a given player has opened by moving the king pawn up two squares (e4) as white, on move number one. What is the percentage of time the player responds to white's e4 opening move, with moving his own king pawn to e5? What percentage of time does he respond by moving his queenside bishop pawn to c5? And so on. If it's not clear, the stat tracking system should also be able to report how many times this player, as black, move his queen to h1, on move number 30. I'm using Parse.com for my back-end as a server (BaaS) service. If I were to create a class that writes strings that identify move number, player color, moved piece, algebraic notation of the square (e.g. "d8") to a file, locally in the file system saves the file to Parse, and deletes the temporary file from file system upon opening the same game in my tableview (a la a "With Friends" game), download this file from Parse, parse through it and retrieve all stats/history, assign all relevant values to variables Is this plan viable, or is there an easier way?

  • HLSL 5 interpolation issues

    - by metredigm
    I'm having issues with the depth components of my shadowmapping shaders. The shadow map rendering shader is fine, and works very well. The world rendering shader is more problematic. The only value which seems to definitely be off is the pixel's position from the light's perspective, which I pass in parallel to the position. struct Pixel { float4 position : SV_Position; float4 light_pos : TEXCOORD2; float3 normal : NORMAL; float2 texcoord : TEXCOORD; }; The reason that I used the semantic 'TEXCOORD2' on the light's pixel position is because I believe that the problem lies with Direct3D's interpolation of values between shaders, and I started trying random semantics and also forcing linear and noperspective interpolations. In the world rendering shader, I observed in the pixel shader that the Z value of light_pos was always extremely close to, but less than the W value. This resulted in a depth result of 0.999 or similar for every pixel. Here is the vertex shader code : struct Vertex { float3 position : POSITION; float3 normal : NORMAL; float2 texcoord : TEXCOORD; }; struct Pixel { float4 position : SV_Position; float4 light_pos : TEXCOORD2; float3 normal : NORMAL; float2 texcoord : TEXCOORD; }; cbuffer Camera : register (b0) { matrix world; matrix view; matrix projection; }; cbuffer Light : register (b1) { matrix light_world; matrix light_view; matrix light_projection; }; Pixel RenderVertexShader(Vertex input) { Pixel output; output.position = mul(float4(input.position, 1.0f), world); output.position = mul(output.position, view); output.position = mul(output.position, projection); output.world_pos = mul(float4(input.position, 1.0f), world); output.world_pos = mul(output.world_pos, light_view); output.world_pos = mul(output.world_pos, light_projection); output.texcoord = input.texcoord; output.normal = input.normal; return output; } I suspect interpolation to be the culprit, as I used the camera matrices in place of the light matrices in the vertex shader, and had the same problem. The problem is evident as both of the same vectors were passed to a pixel from the VS, but only one of them showed a change in the PS. I have already thoroughly debugged the matrices' validity, the cbuffers' validity, and the multiplicative validity. I'm very stumped and have been trying to solve this for quite some time. Misc info : The light projection matrix and the camera projection matrix are the same, generated from D3DXMatrixPerspectiveFovLH(), with an FOV of 60.0f * 3.141f / 180.0f, a near clipping plane of 0.1f, and a far clipping plane of 1000.0f. Any ideas on what is happening? (This is a repost from my question on Stack Overflow)

  • Hough transformation for iris detection in opencv

    - by iva123
    Hi, I wrote the code for iris detection and it works well. Also I can crop the eye location of a face. Now I want to detect the iris of the crop image with applying the Hough transformation(cvHoughCircle). However when I try this procedure, the system is not able to find any circle on the image. Maybe, the reason is, there are noises in the image but I don't think it's the reason. So, how can I detect the iris ? I have the code of binary thresholding maybe I can use it, but I don't know how to do ?? If anyone helps I really appreciated. thx :)
