  • close jquery UI dialog when file download begins

    - by vanillaike
    I am using an ASP.Net MVC site that has a link to an ASP.Net WebForms page that performs the actual download. I would like my jquery ui dialog to close when the download starts. Is there a javascript/jquery event that I can use to accomplish this? I found an example with exactly what I want to do here, but since I'm using MVC instead of WebForms I can't seem to get it to work.

  • Deleteing cache upon submit

    - by user279521
    I have an asp.net web form (c#, .NET framework 3.5) that returns to itself after the user clicks the submit button. I think that some values of the form are cached (some controls in a "placeholder" are out of position... meaning they have moved slightly up or down on the web form). How can I delete the cache after user clicks submit, and ensure that the form reloads fresh, after submit?

  • SSIS - XML Source Script

    - by simonsabin
    The XML Source in SSIS is great if you have a 1 to 1 mapping between entity and table. You can do more complex mapping but it becomes very messy and won't perform. What other options do you have? The challenge with XML processing is to not need a huge amount of memory. I remember using the early versions of Biztalk with loaded the whole document into memory to map from one document type to another. This was fine for small documents but was an absolute killer for large documents. You therefore need a streaming approach. For flexibility however you want to be able to generate your rows easily, and if you've ever used the XmlReader you will know its ugly code to write. That brings me on to LINQ. The is an implementation of LINQ over XML which is really nice. You can write nice LINQ queries instead of the XMLReader stuff. The downside is that by default LINQ to XML requires a whole XML document to work with. No streaming. Your code would look like this. We create an XDocument and then enumerate over a set of annoymous types we generate from our LINQ statement XDocument x = XDocument.Load("C:\\TEMP\\CustomerOrders-Attribute.xml");   foreach (var xdata in (from customer in x.Elements("OrderInterface").Elements("Customer")                        from order in customer.Elements("Orders").Elements("Order")                        select new { Account = customer.Attribute("AccountNumber").Value                                   , OrderDate = order.Attribute("OrderDate").Value }                        )) {     Output0Buffer.AddRow();     Output0Buffer.AccountNumber = xdata.Account;     Output0Buffer.OrderDate = Convert.ToDateTime(xdata.OrderDate); } As I said the downside to this is that you are loading the whole document into memory. I did some googling and came across some helpful videos from a nice UK DPE Mike Taulty http://www.microsoft.com/uk/msdn/screencasts/screencast/289/LINQ-to-XML-Streaming-In-Large-Documents.aspx. Which show you how you can combine LINQ and the XmlReader to get a semi streaming approach. I took what he did and implemented it in SSIS. What I found odd was that when I ran it I got different numbers between using the streamed and non streamed versions. I found the cause was a little bug in Mikes code that causes the pointer in the XmlReader to progress past the start of the element and thus foreach (var xdata in (from customer in StreamReader("C:\\TEMP\\CustomerOrders-Attribute.xml","Customer")                                from order in customer.Elements("Orders").Elements("Order")                                select new { Account = customer.Attribute("AccountNumber").Value                                           , OrderDate = order.Attribute("OrderDate").Value }                                ))         {             Output0Buffer.AddRow();             Output0Buffer.AccountNumber = xdata.Account;             Output0Buffer.OrderDate = Convert.ToDateTime(xdata.OrderDate);         } These look very similiar and they are the key element is the method we are calling, StreamReader. This method is what gives us streaming, what it does is return a enumerable list of elements, because of the way that LINQ works this results in the data being streamed in. static IEnumerable<XElement> StreamReader(String filename, string elementName) {     using (XmlReader xr = XmlReader.Create(filename))     {         xr.MoveToContent();         while (xr.Read()) //Reads the first element         {             while (xr.NodeType == XmlNodeType.Element && xr.Name == elementName)             {                 XElement node = (XElement)XElement.ReadFrom(xr);                   yield return node;             }         }         xr.Close();     } } This code is specifically designed to return a list of the elements with a specific name. The first Read reads the root element and then the inner while loop checks to see if the current element is the type we want. If not we do the xr.Read() again until we find the element type we want. We then use the neat function XElement.ReadFrom to read an element and all its sub elements into an XElement. This is what is returned and can be consumed by the LINQ statement. Essentially once one element has been read we need to check if we are still on the same element type and name (the inner loop) This was Mikes mistake, if we called .Read again we would advance the XmlReader beyond the start of the Element and so the ReadFrom method wouldn't work. So with the code above you can use what ever LINQ statement you like to flatten your XML into the rowsets you want. You could even have multiple outputs and generate your own surrogate keys.

  • dotnet Cologne 2011 : Anmeldung ab 14. März

    - by WeigeltRo
    Am 6.5.2011 findet in Köln die dotnet Cologne 2011 statt, eine von der .NET User Group Köln und der von mir geleiteten Gruppe Bonn-to-Code.Net gemeinsam organisierte Community-Konferenz rund um .NET. Die “dotnet Cologne” hat sich mittlerweile als die große .NET Community- Konferenz in Deutschland etabliert. So war die letztjährige dotnet Cologne 2010 mit 300 Teilnehmern bereits einen Monat im Voraus ausgebucht. Und heise online schrieb: “Inzwischen besitzt die dotnet Cologne ein weites Einzugsgebiet. Die Teilnehmer kommen nicht mehr ausschließlich aus dem Kölner Umfeld, sondern aus allen Teilen Deutschlands [...] Die gute Qualität des Vorjahres in Verbindung mit einem geringen Preis hat sich schnell herumgesprochen, sodass Teilnehmer aus Bayern oder Thüringen keine Ausnahme waren.” Auch in diesem Jahr erwartet die Teilnehmer ein ganzer Tag voll mit Themen rund um .NET. Auf der Website http://www.dotnet-cologne.de sind dazu jetzt die ersten Vorträge, Sprecher sowie Infos zur Anmeldung veröffentlicht. Die Anmeldung ist ab Montag, den 14.3.2011 um 14:00 freigeschaltet. Es empfiehlt sich, schnell zu handeln, denn für die 100 ersten Teilnehmer gilt der “Super-Early Bird” Preis von nur 25,- Euro; diese Plätze waren letztes Jahr in Nullkommanix weg. Die Teilnehmer 101 – 200 zahlen den “Early Bird” Preis von 40,- Euro, ab Platz 201 gilt der “Normalpreis” von 55,- Euro. Aber egal ob “Super-Early”, “Early” oder “Normal”: 25 Vorträge auf 5 Tracks, gehalten von bekannten Namen der .NET Community, dazu den ganzen Tag über Verpflegung und Getränke – das ist zu diesem Preis ein sehr attraktives Angebot. Wir haben damit eine Konferenz organisiert, die wir selbst gerne besuchen würden. Ganz im Sinne “von Entwicklern, für Entwickler”. Was ist neu? Das Feedback vom letzten Jahr war sehr positiv, den Leuten hat’s einfach gut gefallen. Gleichwohl haben wir Feedback-Bögen, Blog-Einträge und Tweets sehr aufmerksam ausgewertet und bei der Organisation berücksichtigt: Der neue Veranstaltungsort, das Komed im Mediapark Köln, ist zentral gelegen und verfügt über günstige Parkmöglichkeiten Die Räumlichkeiten bieten mehr Platz für Teilnehmer, Sponsoren und natürlich auch das Mittagessen Wir haben dieses Jahr einige etwas speziellere Vorträge auf Level 300 und 400 im Programm, um neben fundierten Einführungen in Themengebiete auch “Deep Dives” für Experten anbieten zu können. Längere Pausen zwischen den Vorträgen ermöglichen es den Teilnehmern besser, nach den Vorträgen mit den Sprechern verbleibende Fragen zu klären, sich an den Sponsorenständen Infos zu holen oder einfach Kontakte mit Gleichgesinnten zu knüpfen. Was das Fördern der Kommunikation unter den Teilnehmern angeht, haben wir schon die eine oder andere Idee im Kopf. Aber einiges davon hängt nicht zuletzt von finanziellen Faktoren ab – und damit sind wir schon beim Thema: Es gibt noch Sponsoring-Möglichkeiten! Die dotnet Cologne 2011 ist die Gelegenheit, Produkte vorzustellen, neue Mitarbeiter zu suchen oder generell den Namen einer Firma bei den richtigen Leuten zu platzieren. Nicht ohne Grund unterstützen uns viele Sponsoren dieses Jahr zum wiederholten Mal. Vom Software-Sponsor für die Verlosung bis hin zum Aussteller vor Ort – es gibt vielfältige Möglichkeiten und wir schicken auf Anfrage gerne unsere Sponsoreninfos zu.

  • Dynamic meta description and keyword tags for your MasterPages

    - by Aamir Hasan
     Today we're going to look at a technique for dynamically inserting meta tags into your master pages. By taking control of the head tag and inserting your own HtmlMeta you can easily customise these tags.Might have noticed that when you create a new master page in visual studio your <head> tag gets decorated with a runat="server" attribute.Asp.net doesn't add this kind of decoration to any other html tags (although you are free to add it if you want). So what makes the head tag special?By adding the runat="server" you're giving actually converting the control into a HtmlHead control. That doesn't particularly matter for this tutorial other than to note that given a reference to the head control you get all the extras that come with asp.net controls such as access to its controls collection.The HtmlMeta control lets us wrap up <meta> tags via asp.net code. To add a meta description we need to create an instance, set the name property, the content property, and then add it to the head: asp.net using (C#)protected void Page_Init(object sender, EventArgs e){  // Add meta description tag  HtmlMeta metaDescription = new HtmlMeta();  metaDescription.Name = "Description";  metaDescription.Content = "Short, unique and keywords rich page description.";  Page.Header.Controls.Add(metaDescription);   // Add meta keywords tag  HtmlMeta metaKeywords = new HtmlMeta();  metaKeywords.Name = "Keywords";  metaKeywords.Content = "selected,page,keywords";  Page.Header.Controls.Add(metaKeywords);}asp.net ( VB.NET )Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init  ' Add meta description tag  Dim metaDescription As HtmlMeta = New HtmlMeta()  metaDescription.Name = "Description"  metaDescription.Content = "Short, unique and keywords rich page description."  Page.Header.Controls.Add(metaDescription)   ' Add meta keywords tag  Dim metaKeywords As HtmlMeta = New HtmlMeta()  metaKeywords.Name = "Keywords"  metaKeywords.Content = "selected,page,keywords"  Page.Header.Controls.Add(metaKeywords)End Sub

  • Windows 7 .NET 3.5.1 - 2.0 Slightly Corrupted, How to Repair?

    - by Quinxy von Besiex
    My Windows 7 included .NET installation (3.5 to 2.0) appears very slightly and particularly corrupted and I am trying to fix it without reinstalling Windows or trying to revert to backups. Everything was working and then my hard drive started corrupting a few files and checkdisk found bad clusters so I imaged the drive to a new one. As soon as I booted on the new drive everything worked except programs which call the System.Net.NetworkInformation methods within .NET 3.5 to 2.0 (like Ping() and IsNetworkAvailable()), which immediately crash the app in which the calls are (those calls in .NET 4.0 works fine). Those methods are found inside System.dll, and I assume call native methods which I believe are inside winnsi.dll or iphlpapi.dll or something else (I've not found this yet); I assume it calls native methods because the exception which causes the crash is Fatal Execution Engine Error which people mention is usually related to calling native methods and marshaling data between them. A huge clue about the culprit is likely found in the fact that when I launch the exact same crashing application through a code profiler (which executes the exe and captures stats on which methods took the longest) the app works fine, no crash at all! How could running it within the profiler work and running it outside not work? That seems the key to the mystery. I've used procmon to catch all the registry, filesystem, and network events from the crashing execution and the profiler-run successful execution and compared the two outputs but didn't learn much (I see the moment at which the non-profiled app crashes, but up until then they behave the same, loaded the same modules, ). The only big difference seems to be that at the moment before the app crash the profiler-executed code creates 4-6 new threads and the directly executed code only creates 1-2. I have diffed the files/directories which seemed most relevant (the .NET stuff under Windows and Program Files) pre- and post- disk trouble and seen no changes where I didn't expect any (no obvious file corruption). I have diffed the software and system registry hives pre- and post- disk trouble and seen no changes which seemed relevant. I have created a new user account and cleaned up any environment variables in case environment was related. No change. I did "sfc /scannow" and it found no integrity problems. I tried "ngen update" to regenerate pre-compiled code in case I missed something that might be damaged and nothing changed. I assume I need to repair my .NET installation but because Windows 7 included .NET 3.5 - 2.0 you can't just re-run a .NET installer to redo it. I do not have access to the Windows disks to try to re-install Windows over itself (the computer has a recovery partition but it is unusable); also the drive uses a whole-disk encryption solution and re-installing would be difficult. I absolutely do not want to start from scratch here and install a fresh Windows, reinstall dozens of software packages, try and remember dozens of development-related customizations/etc. Given all that... does anyone have any helpful advice? I need .NET 3.5 - 2.0 working as I am a developer and need to build and test against it. Thanks! Quinxy

  • Make it simple. Make it work.

    - by Sean Feldman
    In 2010 I had an experience to work for a business that had lots of challenges. One of those challenges was luck of technical architecture and business value recognition which translated in spending enormous amount of manpower and money on creating C++ solutions for desktop client w/o using .NET to minimize “footprint” (2#) of the client application in deployment environments. This was an awkward experience, considering that C++ custom code was created from scratch to make clients talk to .NET backend while simple having .NET as a dependency would cut time to market by at least 50% (and I’m downplaying the estimate). Regardless, recent Microsoft announcement about .NET vNext has reminded me that experience and how short sighted architecture at that company was. Investment made into making C++ client that cannot be maintained internally by team due to it’s specialization in .NET have created a situation where code to maintain will be more brutal over the time and  number of developers understanding it will be going and shrinking. Not only that. The ability to go cross-platform (#3) and performance achievement gained with native compilation (#1) would be an immediate pay back. Why am I saying all this? To make a simple point to myself and remind again – when working on a product that needs to get to the market, make it simple, make it work, and then see how technology is changing and how you can adopt. Simplicity will not let you down. But a complex solution will always do.

  • C# 4.0: Covariance And Contravariance In Generics

    - by Paulo Morgado
    C# 4.0 (and .NET 4.0) introduced covariance and contravariance to generic interfaces and delegates. But what is this variance thing? According to Wikipedia, in multilinear algebra and tensor analysis, covariance and contravariance describe how the quantitative description of certain geometrical or physical entities changes when passing from one coordinate system to another.(*) But what does this have to do with C# or .NET? In type theory, a the type T is greater (>) than type S if S is a subtype (derives from) T, which means that there is a quantitative description for types in a type hierarchy. So, how does covariance and contravariance apply to C# (and .NET) generic types? In C# (and .NET), variance applies to generic type parameters and not to the resulting generic type. A generic type parameter is: covariant if the ordering of the generic types follows the ordering of the generic type parameters: Generic<T> = Generic<S> for T = S. contravariant if the ordering of the generic types is reversed from the ordering of the generic type parameters: Generic<T> = Generic<S> for T = S. invariant if neither of the above apply. If this definition is applied to arrays, we can see that arrays have always been covariant because this is valid code: object[] objectArray = new string[] { "string 1", "string 2" }; objectArray[0] = "string 3"; objectArray[1] = new object(); However, when we try to run this code, the second assignment will throw an ArrayTypeMismatchException. Although the compiler was fooled into thinking this was valid code because an object is being assigned to an element of an array of object, at run time, there is always a type check to guarantee that the runtime type of the definition of the elements of the array is greater or equal to the instance being assigned to the element. In the above example, because the runtime type of the array is array of string, the first assignment of array elements is valid because string = string and the second is invalid because string = object. This leads to the conclusion that, although arrays have always been covariant, they are not safely covariant – code that compiles is not guaranteed to run without errors. In C#, the way to define that a generic type parameter as covariant is using the out generic modifier: public interface IEnumerable<out T> { IEnumerator<T> GetEnumerator(); } public interface IEnumerator<out T> { T Current { get; } bool MoveNext(); } Notice the convenient use the pre-existing out keyword. Besides the benefit of not having to remember a new hypothetic covariant keyword, out is easier to remember because it defines that the generic type parameter can only appear in output positions — read-only properties and method return values. In a similar way, the way to define a type parameter as contravariant is using the in generic modifier: public interface IComparer<in T> { int Compare(T x, T y); } Once again, the use of the pre-existing in keyword makes it easier to remember that the generic type parameter can only be used in input positions — write-only properties and method non ref and non out parameters. Because covariance and contravariance apply only to the generic type parameters, a generic type definition can have both covariant and contravariant generic type parameters in its definition: public delegate TResult Func<in T, out TResult>(T arg); A generic type parameter that is not marked covariant (out) or contravariant (in) is invariant. All the types in the .NET Framework where variance could be applied to its generic type parameters have been modified to take advantage of this new feature. In summary, the rules for variance in C# (and .NET) are: Variance in type parameters are restricted to generic interface and generic delegate types. A generic interface or generic delegate type can have both covariant and contravariant type parameters. Variance applies only to reference types; if you specify a value type for a variant type parameter, that type parameter is invariant for the resulting constructed type. Variance does not apply to delegate combination. That is, given two delegates of types Action<Derived> and Action<Base>, you cannot combine the second delegate with the first although the result would be type safe. Variance allows the second delegate to be assigned to a variable of type Action<Derived>, but delegates can combine only if their types match exactly. If you want to learn more about variance in C# (and .NET), you can always read: Covariance and Contravariance in Generics — MSDN Library Exact rules for variance validity — Eric Lippert Events get a little overhaul in C# 4, Afterward: Effective Events — Chris Burrows Note: Because variance is a feature of .NET 4.0 and not only of C# 4.0, all this also applies to Visual Basic 10.

  • Expando Object and dynamic property pattern

    - by Al.Net
    I have read about 'dynamic property pattern' of Martin Fowler in his site under the tag 1997 in which he used dictionary kind of stuff to achieve this pattern. And I have come across about Expando object in c# very recently. When I see its implementation, I am able to see IDictionary implemented. So Expando object uses dictionary to store dynamic properties and is it what, Martin Fowler already defined 15 years ago?

  • Using Open MQ as an Oracle CEP Event Source

    - by seth.white
    I helped an Oracle CEP customer recently who wanted to use Open MQ has an event source for their Oracle CEP application.  In this case, the Oracle CEP application was being used to provide monitoring for an electronic commerce website, however, the steps for configuring Open MQ are entirely independent of the application logic. I thought I would list the configuration steps in a blog post in case they might help others in the future. Note that although the Oracle CEP documentation states that only WebLogic and Tibco JMS are "officially" supported, any JMS implementation that provides a Java client should work with Oracle CEP. The first step is to add an adapter to the application's EPN. This can be done in the usual way, using the Eclipse IDE. The end result is something like the following bit of configuration in the application's Spring application context. Note that the provider attribute value of 'jms-inbound' specifies that the out-of-the-box JMS adapter is being used. <wlevs:adapter id="helloworldAdapter" provider="jms-inbound"> </wlevs:adapter>   Next, configure the inbound adapter so that it can connect to Open MQ in the Oracle CEP configuration file (config.xml). The snippet below provides an example of what this configuration should look like. The exact values specified for jndi-provider-url, jndi-factory, connection-jndi-name, destination-jndi-name elements will depend on your Open MQ configuration.  For example , if the name of your Open MQ topic destination is 'ElectronicCommerceTopic', then you would specify that as the destination-jndi-name.  The name of your Open MQ connection factory goes in the connection-jndi-name element. In my simple example, I also specify in event-type element so that the out-of-the-box JMS adapter will attempt to automatically convert incoming messages to events of type HelloWorldEvent. In a more complex application, one would configure a custom converter on the JMS adapter to convert from messages to events.  The Oracle CEP 11.1.3 documentation describes how to do this.   <jms-adapter> <name>helloworldAdapter</name> <event-type>HelloWorldEvent</event-type> <jndi-provider-url>file:///C:/Temp</jndi-provider-url> <jndi-factory>com.sun.jndi.fscontext.RefFSContextFactory</jndi-factory> <connection-jndi-name>YourJMSConnectionFactoryName</connection-jndi-name> <destination-jndi-name>YourJMSDestinationName</destination-jndi-name> </jms-adapter>   Finally, one needs to package the client-side Open MQ jars so that the classes that they contain are available to the Oracle CEP runtime. The recommended way for doing this in the Oracle CEP 11.1.3 release is to package the classes as a library module or simply place them in the application bundle.  The advantage of deploying the classes as a library module is that they are available to any application that wants to connect to Open MQ. In my case, I packaged the classes in my application bundle. A best practice when you want to include additional jars in your application bundle is to create a 'lib' directory in your Eclipse project and then copy the required jars into that directory.  Then, use the support that Eclipse provides to add the jars to the bundle classpath (which makes the classes part of your application in the same way that regular application classes are), and export all of the classes from your application bundle so that they are available to the Oracle CEP server runtime.  The screenshot below Illustrates how this is done in Eclipse.  The bundle classpath contains two Open MQ jars and all packages in the jars are exported.     Finally, import the javax.jms and javax.naming packages into the application module as these are needed by the Open MQ classes. The screenshot below shows the complete list of package imports for my sample application.       Once you have completed these steps, you should be able to build and deploy your application and begin receiving inbound messages from Open MQ.

  • Why is there no generic implementation of OrderedDictionary in .net?

    - by nonot1
    Why did Microsoft not provide generic implementation of OrderedDictionary? There are a few custom implementations I've seen, including: http://www.codeproject.com/KB/recipes/GenericOrderedDictionary.aspx But why did Microsoft not include it in the base .net library? Surely they had a reason for not building a generic.... but what is it? Prior to posting this message, I did see: http://stackoverflow.com/questions/2629027/no-generic-implementation-of-ordereddictionary But that just confirms that it does not exist. Not why it does not exist. Thanks

  • 302: this blog will be closed

    - by preishuber
    After nearly 7 years I will discontinue blogging on this site. My resources are limited. You can reach my German blog which is used to support my customers. Looking back to a long an interesting journey ASP.NET by ScottGu That was the reason to attend this site and support Microsoft as much as I can. For that I was honored as ASP.NET MVP- thanks again. Meet Scoot several times. Great guy! Forums I have left NNTP forums a few years ago and now Microsoft closed it- It was my idea ;-) AJAX Was the wrong way- JQuery won the game IIS7 That is really a great plattform and the IIS team rules. I am sad that is so silent around that topic. ASP.NET after 2.0 Is no longer my world. I love ASP.NET and ASP.NET Server controls. I hate the discussion about how to follow the holy rules of MVC. Microsoft have dropped the goal to bring ASP.NET to #1 and accepted PHP is it. Facebook & Twittering Microblogging takes over a part of the blogging business. Shorter faster cheaper- or as SteveB mentioned - do more with less. Google Google is taking over the web. I am using Bing every time as I can but Google have more options. Sorry Microsoft you will loose that game. Apple That is not the biggest problem of Microsoft. the Ixxx takes over a small part but big money of the market, but the customers are not strongly linked. New wave new hype- Game over Apple. Silverlight My new home. I can reuse a lot of my skills and love the possibilitys. Silverligth will passing WPF-and strike Flash Windows phone 7 Also my skills fit. I just will use it for fun. I am not really satisfied about what I have heard from MIX. Guys from Redmond, I am sad to say you have been the best Smartphone OS and lost everything. The ADO vNext Story That will be the next mystic point. WCF, REST, JSON, ATOM and now OData. Nothing about SQL commands. LINQ, ORM is also not the final solution for multilayered disconnected async scenarios. Personally I prefere the OData idea and dislike the Swiss Army Knife (German Eierlegende Wollmilchsau) WCF. I am still in INETA Speakers board and I am glad to come to your user group. In all other cases you can hire me over ppedv AG. Good by and have good live.

  • Twitter like character counter - jQuery version

    - by bipinjoshi
    My recent article titled "Displaying a Character Counter for Multiline Textboxes" shows you how to create a character counter like Twitter for multiline textboxes. The articles does so using ASP.NET AJAX client behavior. Here is a jQuery version of the code that does similar job. Note, however, that unlike ASP.NET AJAX client behavior as illustrated in the article the following code takes a "function" based approach to quickly implement similar functionality.http://www.bipinjoshi.net/articles/84e691b2-0306-4911-87bb-875806ba981b.aspx
