  • WCF RIA Services v1.0 Timeouts

    - by Dan Wray
    I have a RIA service methods which return quite a large amount of (binary) data to my silverlight application. The methods themselves (database access etc) complete quickly, but since I upgraded to v1.0 from the RC2 I've been experiencing timeouts, even when I limit the data returned to the smallest objects. Debug shows the method returning, then 20-30 seconds later the silverlight "method complete" event will fire. There is not enough data to cause that much lag. Could anyone suggest why this might be? I've been unable to find any breaking changes documentation specific to the RC2 = 1.0 upgrade. Trying to eliminate any other possible causes also, but this is literally a case of worked before the install, doesn't work now! (also upgraded silverlight 4 tools for vs).

  • How can I specify my own Rhino context in Java?

    - by Dan Howard
    I'm trying to ensure that my Rhino scripts (running under Java 6) are strict so that if a script developer misspells an expression I want an exception to be thrown. Currently what happens is the expression simply evaluates to "undefined". Now according to Mozilla org https://developer.mozilla.org/en/New_in_Rhino_1.6R6 there are features to enable strict checking in the context. I cannot find a working example of this. What I did so far was write a class to extend ContextFactory and then override the hasFeature method. public class ScriptContextFactory extends ContextFactory { protected boolean hasFeature(Context context, int featureIndex) { switch (featureIndex) { case Context.FEATURE_STRICT_EVAL: return true; case Context.FEATURE_STRICT_VARS: return true; } return super.hasFeature(context, featureIndex); } } Then in the Main I set mine to the default. ContextFactory.initGlobal(new ScriptContextFactory()); and I get an illegal state exception. :( Any ideas or samples on how this works? TIA

  • Cannot connect to SQL Server from ASP.NET MVC app

    - by Dan Fergus
    I have an ASP.NET MVC app that has on a hosted server for over a year, connecting to SQL Server. I've had to change hosting services, the new one supports MVC 1.0. I've also moved a non MVC ASP app to the same hosting service. Now, MY MVC based app retturnes this error when I try to validate a user login. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) Now, the non-MVC app can access the exact same database and authenticate users just fine. The MVC app, when run from my dev box connects fine. It also run/connects/authenticates without problem when I install and run the site from an internal SQL 2008 server running IIS 7. I, along with the hosting support techs, am at a loss how the exact same connect string works every where except on the hosted server, and only when run from inside an ASP.NET MVC web app. Any ideas would be greatly appreciated.

  • Tools to build a UI markup language parser

    - by Dan
    For a school project, I need to implement a parser for a (probably XML-based) markup language for User Interfaces. Based on the input it generates a HTML document with various UI components (textareas, inputs, panels, dialogs etc.) Do you have any suggestions for tools/libraries I might use for this? (At school we use Flex and Bison, but we're allowed to use modern tools -- maybe a tool that has the capabilities of both lex and yacc)

  • Simple 2 column CSS layout with nested divs

    - by Dan
    Hello, I have good familiarity with CSS but for some reason I am unable to achieve the result I want in this case. Here is the link to my test site http://danberinger.com/test.html Keep in mind that I want a 2 column layout and that the background wrapper color (gray) is not showing. Instead the body background color image is being put in place of where the wrapper background should be. Any suggestions would be greatly appreciated.

  • Resources for finding Haskell jobs?

    - by Dan
    Where is a good place to go to find a job where I can (frequently) use Haskell? Just to be clear, I am not asking: What's the Haskell market like? Why is Haskell used so little in the industry? What is Haskell actually useful for? Nor am I asking you to tell me that Haskell jobs can't be found. That is the default conclusion if no good responses show up here. I am asking, for the 2 or 3 Haskell jobs that are out there, how can I find them?

  • PL/SQL bulk collect into associative array with sparse key

    - by Dan
    I want to execute a SQL query inside PL/SQL and populate the results into an associative array, where one of the columns in the SQL becomes the key in the associative array. For example, say I have a table Person with columns PERSON_ID INTEGER PRIMARY KEY PERSON_NAME VARCHAR2(50) ...and values like: PERSON_ID | PERSON_NAME ------------------------ 6 | Alice 15 | Bob 1234 | Carol I want to bulk collect this table into a TABLE OF VARCHAR2(50) INDEX BY INTEGER such that the key 6 in this associative array has the value Alice and so on. Can this be done in PL/SQL? If so, how?

  • For loop with a non-integer increment in VB.NET

    - by Dan Tao
    Can a VB.NET For loop be constructed that mimics this C# code? TimeSpan oneDay = TimeSpan.FromDays(1.0); for (DateTime d = startDate; d < endDate; d += oneDay) { // some code } Obviously you could do it without a For loop (i.e., with a While); I'm just curious if there's a certain syntax to construct a VB.NET For loop with a non-integer increment that I'm not aware of.

  • SVN marking file production ready

    - by dan.codes
    I am kind of new to SVN, I haven't used it in detail basically just checking out trunk and committing then exporting and deploying. I am working on a big project now with several developers and we are looking for the best deployment process. The one thing we are hung up on is the best way to tag, branch and so on. We are used to CVS where all you have to do is commit a file and tag it as production ready and if not that code will not get deployed. I see that SVN handles tagging differently then CVS. I figure I am looking at this and making it overly complex. It seems the only way to work on a project and commit files without it being in the production code is to do it in a branch and then merge those changes when you are ready for it to be deployed. I am assuming you could also be working on other code that should be deployed so you would have to be switching between working copies, because otherwise you are working on a branch that isn't getting mixed in with the trunk or production branch? This process seems overly complex and I was wondering if anyone could give me what you think is the best process for managing this.

  • Where about should my main class be created in a project?

    - by Dan
    The problem is where a class should be created in my code. An example is I have a UI class and a main logic class that controls other objects. Should the main logic class create the UI object, or should the UI object create the instance of the main logic class? An explanation of which method is best and why would be ideal. Thanks.

  • Xcode "Build and Archive" from command line

    - by Dan Fabulich
    Xcode 3.2 provides an awesome new feature under the Build menu, "Build and Archive" which generates an .ipa file suitable for Ad Hoc distribution. You can also open the Organizer, go to "Archived Applications," and "Submit Application to iTunesConnect." Is there a way to use "Build and Archive" from the command line (as part of a build script)? I'd assume that xcodebuild would be involved somehow, but the man page doesn't seem to say anything about this. UPDATE Michael Grinich requested clarification; here's what exactly you can't do with command-line builds, features you can ONLY do with Xcode's Organizer after you "Build and Archive." You can click "Share Application..." to share your IPA with beta testers. As Guillaume points out below, due to some Xcode magic, this IPA file does not require a separately distributed .mobileprovision file that beta testers need to install; that's magical. No command-line script can do it. For example, Arrix's script (submitted May 1) does not meet that requirement. More importantly, after you've beta tested a build, you can click "Submit Application to iTunes Connect" to submit that EXACT same build to Apple, the very binary you tested, without rebuilding it. That's impossible from the command line, because signing the app is part of the build process; you can sign bits for Ad Hoc beta testing OR you can sign them for submission to the App Store, but not both. No IPA built on the command-line can be beta tested on phones and then submitted directly to Apple. I'd love for someone to come along and prove me wrong: both of these features work great in the Xcode GUI and cannot be replicated from the command line.

  • Is hardware accelerated CSS3 in Safari 4 & 5 broken, or my CSS and JS?

    - by Dan Forys
    Hi all, I've created a somewhat silly site that shows you the expected weather forecast for any city in the World. On webkit based browsers, when the weather is sunny a sun with CSS3 animated rotated sunbeams appears. This works fine on Chrome. An example (sunny, at the moment) page is: http://willitraintoday.co.uk/iceland/reykjavik/ However, when viewed in Safari 4 or 5 on Mac Snow Leopard, when the sun appears the sky background appears over it. Weirder still, as the cloud containing the advert moves across the sky, it squashes the main text. When the cloud reaches the left edge, the text appears wider than normal and starts squashing down again. I've tried: - Disabling the CSS3 animation; it works fine in Safari - Juggling the z-index of various elements; to no avail Is there something up with my Javascript or CSS, or is the hardware accelerated snow leopard Safari broken in this case? It seems not to happen in Safari 4 on Leopard, but I don't have Leopard any more to test myself. Grateful for any opinions!

  • C# Breakpoint Weirdness

    - by Dan
    In my program I've got two data files A and B. The data in A is static and the data in B refers back to the data in A. In order to make sure the data in B is invalidated when A is changed, I keep an identifier for each of the links which is a long byte-string identifying the data. I get this string using BitConverter on some of the important properties. My problem is that this scheme isn't working. I save the identifiers initially, and with I reload (with the exact same data in A) the identifiers don't match anymore. It seems the bit converter gives different results when I go to save. The really weird thing about it is, if I place a breakpoint in the save code, I can see the identifier it's writing to the file is fine, and the next load works. If I don't place a breakpoint and say print the identifiers to console instead, they're totally different. It's like when my program is running at full-speed the CPU messes up some instructions. This isn't the first time something like this happens to me. I've seen it in other projects. What gives? Has anyone every experienced this kind of debugging weirdness? I can't explain how stopping the program and not stopping it can change the output. Also, it's not a hardware problem because this happens on my laptop as well.

  • How can I pass a javaScript function to a Java Method to act as a callback (Rhino)

    - by Dan Howard
    Hi everyone, Basically I'm trying to pass a javaScript function to a Java method to act as a callback to the script. I can do it - sort of - but the object I receive is a sun.org.mozilla.javascript.internal.InterpretedFunction and I don't see a way to invoke it. Any ideas? Here's what I have so far: var someNumber = 0; function start() { // log is just an log4j instance added to the Bindings log.info("started...."); someNumber = 20; // Test is a unit test object with this method on it (taking Object as a param). test.callFromRhino(junk); } function junk() { log.info("called back " + someNumber); }

  • What ASP.NET MVC project files should I not add to Subversion

    - by Dan
    this is likely a naive question, but I want to do this right the first time. I have a MVC solution which has the following: Data project - C# Services project - C# MVC Web Project - ASP.NET MVC Test Project Currently, I am using the MVC2 source as a means to debug my own code. I do not plan on checking that in, but I realize once I go back to the MVC2 DLL, my solution will change. I'm pretty sure I just shouldn't check in stuff that changes with each build: the bin folder on the Web project, for example. Is there a list of what not to commit to source control? :)

  • How to put 1000 lightweight server applications in the cloud

    - by Dan Bird
    The company I work for sells a commercial desktop/server app that runs on any non dedicated Windows PC or server and uses Tomcat for all interactions with the application. Customers are asking that we host their instance of the application so they don't have to run it locally on their own servers. The app is lightweight and an average server, in theory, could handle 25-50 instances before users would notice a slowdown. However only 1 instance can run per Windows instance (because the application writes to a common registry branch) so we'd need something like VMWare to create 25-50 Windows instances. We know we eventually need to reprogram to make it truly cloud-worthy but what would you recommend for a server farm or whatever for this? We don't have the setup to purchase our own servers so we must use a 3rd party. We have budgeted $500 - $1000 per year per customer for this service. Thanks in advance for your suggestions, experiences and guidance.

  • Accessing contents of NativeWindow in a HTML AIR application?

    - by Dan Scotton
    I'm currently building a HTML/JS AIR application. The application needs to display to the user a different 'window' - dependant on whether this is the first time they've launched the application or not. This part is actually fine and I have the code below to do that: if(!startUp()) { // this simply returns a boolean from a local preferences database that gets shipped with the .air // do first time stuff var windowOptions = new air.NativeWindowInitOptions(); windowOptions.systemChrome = 'none'; windowOptions.type = 'lightweight'; windowOptions.transparent = 'true'; windowOptions.resizable = 'false'; var windowBounds = new air.Rectangle(300, 300, 596, 490); var newHtmlLoader = air.HTMLLoader.createRootWindow(true, windowOptions, true, windowBounds); newHtmlLoader.load(new air.URLRequest('cover.html')); } else { // display default window // just set nativeWindow.visible = true (loaded from application.xml) } However, what I want to be able to do is manipulate the html content from within cover.html after it has loaded up. There seems to be plenty of tutorials online of how to move, resize, etc. the NativeWindow, but I simply want access to the NativeWindow's HTML content. For example, how would I add a new paragraph to that page? I've tried the following: newHtmlLoader.window.opener = window; var doc = newHtmlLoader.window.opener.document.documentElement; Using AIR's Introspector console, ....log(doc) returns [object HTMLHtmlElement]. Hmm, seems promising right? I then go on to try: var p = document.createElement('p'); var t = document.createTextNode('Insert Me'); p.appendChild(t); doc.appendChild(p); ...but nothing gets inserted. I've also tried the following replacements for doc: var doc = newHtmlLoader.window.opener.document.body; // .log(doc) -> [object HTMLBodyElement] var doc = newHtmlLoader.window.opener.document; // .log(doc) -> Error: HIERARCHY_REQUEST_ERR: DOM Exception 3 ...as well as the following with jQuery: $(doc).append('<p>Insert Me</p>'); // again, nothing So, anyone had any experience in accessing a NativeWindow's inner content programmatically? Any help will be greatly appreciated.

  • Programmatically downloaded file is larger than it should be

    - by Dan Revell
    I'm trying to download a file from SharePoint. The file itself is an InfoPath template although this is probably inconsequential. If I put the url into internet explorer and save the file to disk, it comes in at 4.47KB and works correctly. If I try to download from the same Url in code the it comes back as 21.9KB and is corrupt. Why it's coming down as corrupt I'm trying to work out. The following are two ways of downloading the file that both produce the corrupt file at 21.9KB: /// web client { WebClient wc = new WebClient(); wc.Credentials = CredentialCache.DefaultCredentials; wc.DownloadFile(templateUri, file); byte[] bytes = wc.DownloadData(templateUri); } /// web request { WebRequest request = WebRequest.Create(templateUri); request.Credentials = CredentialCache.DefaultCredentials; WebResponse responce = request.GetResponse(); StreamReader sr = new StreamReader(responce.GetResponseStream()); byte[] bytes = System.Text.Encoding.UTF8.GetBytes(sr.ReadToEnd()); } And this is how I write the data to disk using (FileStream fs = new FileStream(file, FileMode.Create, FileAccess.Write)) { fs.Write(bytes, 0, bytes.Length); }

  • Cannot Translate to SQL using Select(x => Func(x))

    - by Dan
    I'm slowly learning the ins and outs of LINQtoSQL, but this is confusing me. Here is the statement I have: IQueryable<IEvent> events = (from e in db.getEvents() select e).Select(x => SelectEvent(x, null)); What the SelectEvent does can be explained in this answer here. I am not using the .toList() function as I don't want potentially thousands of records brought into memory. public IEvent SelectEvent(SqlServer.Event ev, EventType? type) { // Create an object which implements IEvent // I don't have the code in front of me, so forgive the lack of code } My question is really for the Select() method. I get the "Cannot translate to SQL" error and the Select() is listed in the error message. Clueless on this one :-/.

  • How to approach parallel processing of messages?

    - by Dan
    I am redesigning the messaging system for my app to use intel threading building blocks and am stumped trying to decide between two possible approaches. Basically, I have a sequence of message objects and for each message type, a sequence of handlers. For each message object, I apply each handler registered for that message objects type. The sequential version would be something like this (pseudocode): for each message in message_sequence <- SEQUENTIAL for each handler in (handler_table for message.type) apply handler to message <- SEQUENTIAL The first approach which I am considering processes the message objects in turn (sequentially) and applies the handlers concurrently. Pros: predictable ordering of messages (ie, we are guaranteed a FIFO processing order) (potentially) lower latency of processing each message Cons: more processing resources available than handlers for a single message type (bad parallelization) bad use of processor cache since message objects need to be copied for each handler to use large overhead for small handlers The pseudocode of this approach would be as follows: for each message in message_sequence <- SEQUENTIAL parallel_for each handler in (handler_table for message.type) apply handler to message <- PARALLEL The second approach is to process the messages in parallel and apply the handlers to each message sequentially. Pros: better use of processor cache (keeps the message object local to all handlers which will use it) small handlers don't impose as much overhead (as long as there are other handlers also to be run) more messages are expected than there are handlers, so the potential for parallelism is greater Cons: Unpredictable ordering - if message A is sent before message B, they may both be processed at the same time, or B may finish processing before all of A's handlers are finished (order is non-deterministic) The pseudocode is as follows: parallel_for each message in message_sequence <- PARALLEL for each handler in (handler_table for message.type) apply handler to message <- SEQUENTIAL The second approach has more advantages than the first, but non-deterministic ordering is a big disadvantage.. Which approach would you choose and why? Are there any other approaches I should consider (besides the obvious third approach: parallel messages and parallel handlers, which has the disadvantages of both and no real redeeming factors as far as I can tell)? Thanks!

  • How do I pass a DBNull value to a parameterized SELECT statement?

    - by Dan
    I have a SQL statement in C# (.NET Framework 4 running against SQL Server 2k8) that looks like this: SELECT [Column1] FROM [Table1] WHERE [Column2] = @Column2 The above query works fine with the following ADO.NET code: DbParameter parm = Factory.CreateDbParameter(); parm.Value = "SomeValue"; parm.ParameterName = "@Column2"; //etc... This query returns zero rows, though, if I assign DBNull.Value to the DbParameter's Value member even if there are null values in Column2. If I change the query to accommodate the null test specifically: SELECT [Column1] FROM [Table1] WHERE [Column2] IS @Column2 I get an "Incorrect syntax near '@Column2'" exception at runtime. Is there no way that I can use null or DBNull as a parameter in the WHERE clause of a SELECT statement?

  • Have you read any ASP.NET MVC 2.0 book?

    - by Dan Dumitru
    I'm sorry for asking yet another "best [insert-technology] book". I know a bit of MVC, I want to start a project in MVC 2 and a good book would be really helpful. Usually, after a while, people come to a consensus what are the top 2-3 books for learning a given technology. Have you read any ASP.NET MVC 2.0 book? If so, how was it?
