  • What's all the hype over objectsets in Entity Framework 4?

    - by Kohan
    I am an intermediate user of EF in .net 3.5 and have recently moved to working with .net 4. One thing i keep coming across when reading various tutorials is the use of ObjectSets instead of ObjectQuerys and that they are a great new feature. What is so great about them? Reading this MSDN article titled "Working with ObjectSet (Entity Framework)" It shows two examples on how to add a Product.. one for 3.5 and another for 4.0. http://msdn.microsoft.com/en-us/library/ee473442.aspx Through my lack of knowledge I am possibly bringing up a seperate point here, but i never added a Product like this: //In .NET Framework 3.5 SP1, use the following code: using (AdventureWorksEntities context = new AdventureWorksEntities()) { // Add the new object to the context. context.AddObject("Products", newProduct); } I would have just used context.AddToProducts(newProduct); Please enlighten me. Kind regards, Kohan

    - by flipflopmedia
    Okay, so I got jQuery to get along with MooTools with one script, by adding this at the top of the jQuery script: var $j = jQuery.noConflict(); and then replacing every: $( with $j( But how would you get MooTools to like the following script that using jQuery??

  • Trouble with Native OpenGL Renderer

    - by CaseyB
    I am using Native code to render OpenGL in Android and I get periodic errors that look like this: ERROR/IMGSRV(1435): frameresource.c:610: WaitUntilResourceIsNotNeeded: PVRSRVEventObjectWait failed ERROR/IMGSRV(1018): sgxif.c:124: WaitForRender: PVRSRVEventObjectWait failed ERROR/IMGSRV(1435): osfunc_um.c:318: PVRSRVEventObjectWait: Error 13 returned Once these errors come up I have to restart the phone or the rendering won't start again correctly. I have done a lot of web searching and I can't find out what could be the cause of these errors. Does anyone else have any suggestions?

  • Print gif using java on a 4x6" paper

    - by Wienczny
    What is the best way in Java to print a gif given as byte[] or ByteArrayInputStream on a paper with a size of 4x6 inches? This: PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet(); aset.add(new MediaSize(4, 6, Size2DSyntax.INCH)); aset.add(new Copies(1)); PrintService[] pservices = PrintServiceLookup.lookupPrintServices(DocFlavor.INPUT_STREAM.GIF, aset); DocPrintJob printJob = pservices[0].createPrintJob(); Doc doc = new SimpleDoc(sap.getGraphicImageBytes(), DocFlavor.INPUT_STREAM.GIF, null); printJob.print(doc, aset); does not work because the MediaSize is not a PrintRequestAttribute. This should be almost the same as in Package javax.print Description

  • Get Cell RSSI(Network Signal Strength) on Android 1.5

    - by Brandon
    Is there any way to retrieve the current cellular Signal Strength (RSSI) on Android 1.5? I know there's a way to listen for signal strength updates through the TelephonyManager, but this seems to only give a "state," not a numeric value. Is using the RSSI field on a neighboring cell fairly accurate? I'm guessing not, but I'm running out of ideas.

  • Call asp.net mvc Html Helper within custom html helper with expression parameter

    - by Frank Michael Kraft
    I am trying to write an html helper extension within the asp.net mvc framework. public static MvcHtmlString PlatformNumericTextBoxFor<TModel>(this HtmlHelper instance, TModel model, Expression<Func<TModel,double>> selector) where TModel : TableServiceEntity { var viewModel = new PlatformNumericTextBox(); var func = selector.Compile(); MemberExpression memExpession = (MemberExpression)selector.Body; string name = memExpession.Member.Name; var message = instance.ValidationMessageFor<TModel, double>(selector); viewModel.name = name; viewModel.value = func(model); viewModel.validationMessage = String.Empty; var result = instance.Partial(typeof(PlatformNumericTextBox).Name, viewModel); return result; } The line var message = instance.ValidationMessageFor<TModel, double>(selector); has a syntax error. But I do not understand it. The error is: Fehler 2 "System.Web.Mvc.HtmlHelper" enthält keine Definition für "ValidationMessageFor", und die Überladung der optimalen Erweiterungsmethode "System.Web.Mvc.Html.ValidationExtensions.ValidationMessageFor(System.Web.Mvc.HtmlHelper, System.Linq.Expressions.Expression)" weist einige ungültige Argumente auf. C:\Projects\WorkstreamPlatform\WorkstreamPlatform_WebRole\Extensions\PlatformHtmlHelpersExtensions.cs 97 27 WorkstreamPlatform_WebRole So according to the message, the parameter is invalid. But the method is actually declared like this: public static MvcHtmlString ValidationMessageFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression); So actually it should work.

  • Vertical-centering and overflow Excel-style in CSS?

    - by Eric Grange
    Is there a way to perform a vertical centering of a variable-sized multi-line content within a fixed-size div, with hidden overflow? The aim would be to reproduce what you can see in Excel cells: when the content fits the container, it should be vertically centered, when it is larger, the parts that overflow should be hidden (and the content still vertically aligned), like in an Excel cell whose neighbours aren't empty. I know how to vertically center using CSS, I know how to hide overflow when the content isn't vertically centered, but I've no idea how to do both at the same time... Is Javascript the only answer? The trick is that CSS positioning approaches don't work with variable-sized content (my content is dynamic text), and when you use display:table-cell, it effectively disables CSS overflow control (and the container grows to accomodate the content).

  • Configure Tomcat to send web pages compatible to IE 7 or 6

    - by Spiderman
    I have got an application that is not compatible to work using IE8 browser. I am looking for a way to to configure Tomcat on which this application run, so the pages could be read by IE8 and treated as if they are IE7 or IE6 By googling so far I found a possible suggestion which say to add to the http response the header: X-UA-Compatible: IE=EmulateIE7 here that tell IE8 to be like IE7. The problem is that this way requires adding a filter that should be added on application level. I'd like to know if any of you is familiar with a more generic way that Tomcat enables to send its http content to be IE7 (or IE6) compatible ?

  • Why doesn't .NET find the OpenSSL.NET dll?

    - by Lazlo
    EDIT (the whole question, it was too unclear) I want to use OpenSSL.NET The OpenSSL.NET install instructions page: INSTALL Make sure you have libeay32.dll and ssleay32.dll in the current working directory of your application or in your PATH. DONE In your .NET project, add a reference to the ManagedOpenSsl.dll assembly. DONE I have put libeay32.dll and ssleay32.dll in both my bin/Debug and bin/Release directories. I have also put them in system32. Here is my FULL code: using System; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { try { OpenSSL.Crypto.RSA rsa = new OpenSSL.Crypto.RSA(); } catch (Exception e) { Console.WriteLine(e.InnerException.Message); } Console.Read(); } } } I get the following error: (Unable to load DLL 'libeay32') Here is the Process Monitor log (upon request): What am I doing wrong? Why isn't the DLL found?

  • Win7 recognizing 100% of my RAM some places, not others.

    - by stickynips
    Before you go blaming it on a 32bit OS, I'm running Win7 64bit. I have 4x 1GB sticks of RAM installed. I recently RMA'd one stick and installed the replacement. It would seem that parts of my system are recognizing it and others aren't. Both System Properties and dxdiag show the full 4GB, but task manager and rainmeter are only reporting 3GB. What's numbers should I trust and how can I fix this? Here's screenshots of what I'm seeing.

  • Strange WiFi problem - network is "not connected" but works

    - by GalacticCowboy
    Background I'm using a Windows XP tablet PC connected to my home network. I do broadcast the SSID, but otherwise the wireless network is locked down as tight as I can make it - WPA2 with a strong key, MAC filtering, etc. I've had this computer for about 4 years and the router for about 6 months. Before that, the previous router was set up in the same way, and I've never had any particular problems. Problem This morning - as I type this, as a matter of fact - Windows is reporting that none of my network connections are connected. Yet somehow my Internet connectivity still works! ipconfig reports a valid IP address, domain, etc., even though Windows apparently doesn't know about it. I tried repairing the connection and it had no effect - the repair eventually timed out. I'm pretty sure that I could reboot the computer and/or the router, etc. and it would fix the problem. However, I'm more interested in knowing if any of you have ever seen anything like this, and what might have caused it? Since it works I'm not inclined to mess with it too much. My concern is that it's a precursor to bigger problems.
