• Loading remote assembly from the webservice with reflection

  - by Myat Htut

  I am using Assembly.LoadFrom within a web service to load assemblies from a web site. but the problem is it is in the virutal directory and the server.mappath parses the url like \share\mydll.dll and loadform method failed. Is there anyway to reference dll from the remote location? I've tried passing the url (http:\localhost\downloadable\mydll.dll) and again it got "Could not load file or assembly 'http:\localhost\downloadable\mydll.dll' or one of its dependencies. HTTP download of assemblies has been disabled for this appdomain. (Exception from HRESULT: 0x80131048)"

• jQuery - Add click event to Div and go to first link found

  - by LuckyShot

  Hi guys, I think I've been too much time looking at this function and just got stuck trying to figure out the nice clean way to do it. It's a jQuery function that adds a click event to any div with a click CSS class found in the page and when clicked it redirects the user to the first link found in the div. function clickabledivs() { $('.click').each( function (intIndex) { $(this).bind("click", function(){ window.location = $( "#"+$(this).attr('id')+" a:first-child" ).attr('href'); }); } ); } The code simply works although I'm pretty sure there is a fairly better way to accomplish it, specially the selector I am using: $( "#"+$(this).attr('id')+" a:first-child" ) looks too long and slow. Any ideas? Please let me know if you need more details. Thanks! PS: I've got some jQuery benchmarking reference from Project2k.de here: http://blog.projekt2k.de/2010/01/benchmarking-jquery-1-4/

• Why is a fixed size buffers (arrays) must be unsafe?

  - by brickner

  Let's say I want to have a value type of 7 bytes (or 3 or 777). I can define it like that: public struct Buffer71 { public byte b0; public byte b1; public byte b2; public byte b3; public byte b4; public byte b5; public byte b6; } A simpler way to define it is using a fixed buffer public struct Buffer72 { public unsafe fixed byte bs[7]; } Of course the second definition is simpler. The problem lies with the unsafe keyword that must be provided for fixed buffers. I understand that this is implemented using pointers and hence unsafe. My question is why does it have to be unsafe? Why can't C# provide arbitrary constant length arrays and keep them as a value type instead of making it a C# reference type array or unsafe buffers?

• Capture Flash Audio in 4.7 Edge?

  - by emcmanus

  Is there a way to capture plugin (Flash) audio before it gets to the sound card? I'd like to record plugin audio, hopefully without actually playing the sound. Capturing audio at the device level is an absolute last resort, as the application would pick up all system audio rather than just the Webkit plugin. I'm aware of the recent switch back from QTMultimedia; is this possible with phonon? I spent the night looking for some way to access the phonon graph via QWebFrame (or any of the QtWebkit widgets) -- and didn't turn up much. I also started digging through QTWebkit, particularly NPAPI, without success. For reference, I'm using the edge version of 4.7 (6aa50af000f85cc4497749fcf0860c8ed244a60e) This seems to be a fairly challenging problem. Any hints would be greatly appreciated.

• dynamically created datagridview columns not accessible unless added to a form...why?

  - by deostroll

  We simply created a DataGridView control dynamically and bound it to a DataTable. We were tying to style certain columns. But, when we tried to access the columns we got a null reference. On further investigation we found that if we add the DataGridView control to the main form, and then try to access its columns, it works fine!!! Code which throws error: DataGridView gv = new DataGridView(); gv.DataSource = GetDataTable(); //binding it to datatable Debug.Assert(gv.Columns == null); Code which works fine: DataGridView gv = new DataGridView(); gv.DataSource = GetDataTable(); //binding it to datatable this.Controls.Add(gv); //adding to form Debug.Assert(gv.Columns == null); //the assertion fails! Why is this behaviour so? Is there a workaround for this?

• Recording Audio through RTMP/Rails

  - by Lowgain

  I am in the process of building a rails/flex application which requires audio to be recorded and then stored in our amazon s3 account. I have found no alternative to using some form of RTMP server for recording audio through flash, but our hosting environment will not allow us to install anything like FMS, Red5, etc. Is there any existing Ruby/Rails RTMP solution that will allow audio recording? If not, is it possible for Rails to at least intercept the RTMP stream and then I can hope to reference red5 or something for parsing the data (long shot, I know)? The other alternative I can think of is hosting a red5 server on another host and communicating with our rails app once the saving/uploading is done, which is not preferred. Am I going to have any luck here?

• How to be sure that my MVC project is running on the correct version after upgrade to vs2010?

  - by Stephane

  I just installed visual studio 2010 and upgraded my MVC project (which was running on MVC RC2 in visual studio 2008). visual studio 2010 updated every project file to target the framework 4.0. But the system.web.dll is pointing to C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 2\Assemblies\System.Web.Mvc.dll in VS2010 object browser, I have every dll showing up in multiple versions as expected (3.5.0.0 and 4.0.0.0) except for the System.Web.Mvc dll which doesn't show any version and points to the path I mentioned above. Isn't this namespace point to the Framework folder like the System.Web namespace? C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\System.Web.dll

• Specification of Extended Properties in OleDb connection string?

  - by Monty

  At the moment I'm searching for properties for a connection string, which can be used to connect to an Excel file in readonly mode. Searching Google gets me a lot of examples of connection strings, but I can't seem to find a specification of all possibilities in the 'Extended Properties' section of the OleDb connection string. At the moment I've this: Provider = Microsoft.Jet.OLEDB.4.0; Data Source = D:\Data\Customers.xls; Extended Properties = 'Excel 8.0; Mode=Read; ReadOnly=true; HDR=Yes'; However... I've composed this by examples. So questions: 1. What is a decent source for OleDb Connection String documentation/reference? 2. Is the above connection string indeed connecting to the Excel file in readonly mode? Thanks!

• Practical differences between classes and structs in .net (not conceptual)?

  - by Gulshan

  Whenever I tried to search about differences between classes and structs in C# or .net, I ended up with the conceptual overview of the two things like value type or the reference type, where the variables are allocated etc. But I need some practical differences. I have found some like different behavior of assignment operator, having constructors etc. Can anybody provide some more practical differences which will be directly useful while coding? Like the things works with one but not with other or same operation showing different behavior. And some common mistakes regarding these two. Also please suggest where to consider using a struct instead of a class. And where the structs should not be used.

• Database connection management in Spring

  - by ria

  Do we have to explicitly manage database resources when using Spring Framework.. liking closing all open connections etc? I have read that Spring relieves developer from such boiler plate coding...

• Looking for some thoughts on an image printing app

  - by Alex

  Hey All, Im looking for thoughts/advice. I have an upcoming project (all .net) that will require the following: pulls data once a day from an online service provider based on certain criteria. saves data locally for reference and reporting the data thats pulled will be used to create gift cards. So after the data is loaded, a process will run to generate "virtual cards" and send them to a network printer. Once printed, the system will updated the local data recording a successful or failed print. My initial thought was to create a windows service to pull the data...but then I couldnt decide how I was going to put a "virtual card" together and get it to print. Then I considered doing it as a WPF app. I figure that will give me access to the graphics and printing ability. Maybe neither of these are the right direction....Any ideas or thoughts would be greatly appreciated. Alex

• c#-excel interop - create chart on workbook as opposed to in a sheet

  - by david.barkhuizen

  Using c# MS Excel interop library, I would like to programmatically create a new chart on the workbook, as opposed to on an a sheet. The code below allows me to create a chart on an existing _Worksheet (sheet). using using Microsoft.Office.Interop.Excel; _Worksheet sheet; (assume this is a reference to a valid _Worksheet object) ChartObjects charts = (ChartObjects)sheet.ChartObjects(Type.Missing); ChartObject chartObject = (ChartObject)charts.Add(10, 80, 300, 250); Chart chart = chartObject.Chart; chart.ChartType = XlChartType.xlXYScatter; Does anyone know how to rather go about creating a chart on the workbook (i.e. where the chart is the sheet).

• Autofac / MVC4 / WebApi (RC) Dependency Injection issue after upgrading from beta

  - by George D.

  var resolver = new AutofacWebApiDependencyResolver(container); configuration.ServiceResolver.SetResolver(resolver); after updating to ASP.NET MVC4 (RC) I get the following error: 'System.Web.Http.HttpConfiguration' does not contain a definition for 'ServiceResolver' and no extension method 'ServiceResolver' accepting a first argument of type 'System.Web.Http.HttpConfiguration' could be found (are you missing a using directive or an assembly reference?) I realize after reading this (http://www.asp.net/web-api/overview/extensibility/using-the-web-api-dependency-resolver) that these interfaces have changed, but I am not sure how to apply this change to how I use Autofac. Do i need to wait for a new release from Autofac or is there another way I can get past this.

• C++11 VS 2012 functor seems to choke when I have more than 5 parameters

• How to make Spring accept non-void setters?

  - by Chris

  Hi, I have an API which I am turning into an internal DSL. As such, most methods in my PoJos return a reference to this so that I can chain methods together declaratively as such (syntactic sugar). myComponent .setID("MyId") .setProperty("One","1") .setProperty("Two","2") .setAssociation(anotherComponent) .execute(); My API does not depend on Spring but I wish to make it 'Spring-Friendly' by being PoJo friendly with zero argument constructors, getters and setters. The problem is that Spring seems to not detect my setter methods when I have a non-void return type. The return type of this is very convenient when chaining together my commands so I don't want to destroy my programmatic API just be to compatible with Spring injection. Is there a setting in Spring to allow me to use non-void setters? Chris

• Find package name for Android apps to use Intent to launch Market app from web

  - by eom

  I'm creating a mobile website that will include a page from which people can download relevant apps that we recommend. I've found instructions for creating the links to launch the Market but this assumes that you are the developer of the app in question and know the exact package name. Is there any way to get the package name, other than just contacting the developers and asking? Also, it turns out that those instructions don't really work for creating web hyperlinks. They only give you a URI to reference in a string of Java code in another Android app. Our site is in Drupal, so Java is not going to work. For the iPhone, I found easy instructions for getting the URL/link style I need from the iTunes store, so I'm looking for info like that.

• Static libraries, dynamic libraries, DLLs, entry points, headers ... how to get out of this alive?

  - by tunnuz

  Hello, I recently had to program C++ under Windows for an University project, and I'm pretty confused about static and dynamic libraries system, what the compiler needs, what the linker needs, how to build a library ... is there any good document about this out there? I'm pretty confused about the *nix library system as well (so, dylibs, the ar tool, how to compile them ...), can you point a review document about the current library techniques on the various architectures? Note: due to my poor knowledge this message could contain wrong concepts, feel free to edit it. Thank you Feel free to add more reference, I will add them to the summary. References Since most of you posted *nix or Windows specific references I will summarize here the best ones, I will mark as accepted answer the Wikipedia one, because is a good start point (and has references inside too) to get introduced to this stuff.

• Adding AllowPartiallyTrustedCallersAttribute To Paypal ASP.NET SDK

  - by snwr

  Currently, I cannot use Paypal Pro on my host (GoDaddy) because it requires Full trust level. After digging in Google, it seems a workaround is possible by adding AllowPartiallyTrustedCallersAttribute to the Paypal assembly. I have seen code samples that use AllowPartiallyTrustedCallersAttribute in their AssemblyInfo.cs file, however, I've yet to run into a code example that also happens to be using PayPal. My question is where should the AllowPartiallyTrustedCallersAttribute be added in my project if my objective is to make the PayPal assembly work? I have tried adding it to my AssemblyInfo.cs for the project that contains the entire website, but I have not been successful. At this point, any insight or shot in the dark would be greatly appreciated. Even if someone could point me in the general direction of some documentation I would be grateful.

• What open source database platform is most easily transferred from my personal machine into a window

  - by Tom

  I would like eventual interaction with MS Dynamics SL and/or MindTouch Core (running on WMware) for eventual intranet and/or internet display. I guess I am asking for front and back end recommendations for a database I am constructing, but since this is my first major project I would greatly appreciate any help and advice. I would also love an opportunity to learn a new language so the code base could be in any language. I do have a few more related questions for discussion; What is the viability of using Google hosting to provide the service to the public for free? Should I implement plone or another CMS if I have a large amount of output? Is there a structuring questionnaire or standards publication I could reference? Does UML diagramming provide additional options for portability? Thank you.

• How to center an R plot

  - by ConnorG

  I'm working on visualizing a matrix in R (almost exactly like http://reference.wolfram.com/mathematica/ref/MatrixPlot.html), and I've been using image(<matrix>,axes=FALSE) to draw the picture. However, I noticed that with the y-axis turned off, the plot isn't centered--the space is still there for the axis ticks + label. I can finagle some centering with par(oma=c(0,0,0,2.5)) but this seems inefficient and error-prone (if my matrix were to change dimensions/become non-square). Is there a better way to force the graphic to center? The right hand margin is significantly smaller than the left.

• JavaScript function binding (this keyword) is lost after assignment

  - by Ding

  this is one of most mystery feature in JavaScript, after assigning the object method to other variable, the binding (this keyword) is lost var john = { name: 'John', greet: function(person) { alert("Hi " + person + ", my name is " + this.name); } }; john.greet("Mark"); // Hi Mark, my name is John var fx = john.greet; fx("Mark"); // Hi Mark, my name is my question is: 1) what is happening behind the assignment? var fx = john.greet; is this copy by value or copy by reference? fx and john.greet point to two diferent function, right? 2) since fx is a global method, the scope chain contains only global object. what is the value of this property in Variable object?

• JSF Render response programatically

  - by Shamik

  I have one parent page with a parentManagedBean (attached to Session Scope). On click of a button on this parent page, one popup comes which has a childManagedBean (attached to Request scope). Now ChildManagedBedan holds a reference to parentManaged bean thru JSFs managed Property feature. On this popup window, user selects some option which populates a large value object class. I use the managed property of childMnaagedBean to set the values from this large object to that of parentmanagedbean. Problem is - The parent page shows a link, on click of which a popup comes, on selection of the popup, the popup disappears and set the values to the parentManaged bean.So far so good, but the newly set values need to appear on the parent page. This is where I am stuck. How to programatically render the master page/render page when I am at the child managed bean... is there a way I can get handle of the parent page and refresh it ?

• resolving localhost in php so can be views outside VM

  - by DA

  I'm running Windows 7. Within, I'm running Virtualbox and Ubuntu. Within Ubuntu, I'm running Apache and using PHP codeigniter. To reference our CSS and JS files, we use this syntax: <?php echo site_url('css/styles.css'); ?> When viewing the site locally (within Ubuntu VM) that resolves to: http://localhost/styles.css So works fine. The catch is when I access that site from within Windows 7 (for IE testing). To access the site in Windows 7, I refer to the IP address of the VM: http://xx.x.x.x/ That loads the site but, alas, all the site_url variables are still being rewritten as 'localhost'. Said files obviously don't exist on the localhost of my windows 7. Is there a way around this short of just hard-coding relative links in my PHP file?

• How does the Garbage Collector decide when to kill objects held by WeakReferences?

  - by Kennet Belenky

  I have an object, which I believe is held only by a WeakReference. I've traced its reference holders using SOS and SOSEX, and both confirm that this is the case (I'm not an SOS expert, so I could be wrong on this point). The standard explanation of WeakReferences is that the GC ignores them when doing its sweeps. Nonetheless, my object survives an invocation to GC.Collect(GC.MaxGeneration, GCCollectionMode.Forced). Is it possible for an object that is only referenced with a WeakReference to survive that collection? Is there an even more thorough collection that I can force? Or, should I re-visit my belief that the only references to the object are weak?
