• Java jasper report NullPointerException

  - by William Welch

  I am new to Java and I am running into this issue that I can't figure out. I inherited this project and I have the following code in one of my scriptlets: DefaultLogger.logMessage("DEBUG path: "+ reportFile.getPath()); DefaultLogger.logMessage("DEBUG parameters: "+ parameters); DefaultLogger.logMessage("DEBUG jr: "+ jr); bytes = JasperRunManager.runReportToPdf(reportFile.getPath(), parameters, jr); And I am getting the following results (the fourth line there is line 287 in FootwearReportsServlet.doGet): DEBUG path: C:\Development\JavaWorkspaces\Workspace1\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\RSLDevelopmentStandard\reports\templates\footwear\RslFootwearReport.jasper DEBUG parameters: {class_list_subreport=net.sf.jasperreports.engine.JasperReport@b07af1, signature_path=images/logo_reports.jpg, submission_id=20070213154168780, test_results_subreport=net.sf.jasperreports.engine.JasperReport@5795ce, logo_path=images/logos_3.gif, report_connection_secondary=com.mysql.jdbc.JDBC4Connection@2c39d2, testing_packages_subreport=net.sf.jasperreports.engine.JasperReport@1883d5f, signature_path2=images/logo_reports.jpg, tpid_subreport=net.sf.jasperreports.engine.JasperReport@17531fd, first_page_subreport=net.sf.jasperreports.engine.JasperReport@12504e0} DEBUG jr: net.sf.jasperreports.engine.data.JRMapCollectionDataSource@1630eb6 Apr 29, 2010 4:15:13 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet FootwearReportsServlet threw exception java.lang.NullPointerException at net.sf.jasperreports.engine.fill.JRFiller.fillReport(JRFiller.java:89) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:601) at net.sf.jasperreports.engine.JasperFillManager.fillReport(JasperFillManager.java:517) at net.sf.jasperreports.engine.JasperRunManager.runReportToPdf(JasperRunManager.java:385) at com.rsl.reports.FootwearReportsServlet.doGet(FootwearReportsServlet.java:287) at javax.servlet.http.HttpServlet.service(HttpServlet.java:617) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Unknown Source) What I can't figure out is where the null reference is. From the debug lines I can see that each parameter has a value. Could it be referring to a bad path to one of the images? Any ideas? For some reason my server won't start in debug mode in Eclipse so I am having trouble figuring this out.

• Binding Image.Source to String in WPF ?

  - by Mohammad

  I have below XAML code : <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" DataContext="{Binding RelativeSource={RelativeSource Self}}" WindowStartupLocation="CenterScreen" Title="Window1" Height="300" Width="300"> <Grid> <Image x:Name="TestImage" Source="{Binding Path=ImageSource}" /> </Grid> </Window> Also, there is a method that makes an Image from a Base64 string : Image Base64StringToImage(string base64ImageString) { try { byte[] b; b = Convert.FromBase64String(base64ImageString); MemoryStream ms = new System.IO.MemoryStream(b); System.Drawing.Image img = System.Drawing.Image.FromStream(ms); ////////////////////////////////////////////// //convert System.Drawing.Image to WPF image System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(img); IntPtr hBitmap = bmp.GetHbitmap(); System.Windows.Media.ImageSource imageSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions()); Image wpfImage = new Image(); wpfImage.Source = imageSource; wpfImage.Width = wpfImage.Height = 16; ////////////////////////////////////////////// return wpfImage; } catch { Image img1 = new Image(); img1.Source = new BitmapImage(new Uri(@"/passwordManager;component/images/TreeView/empty-bookmark.png", UriKind.Relative)); img1.Width = img1.Height = 16; return img1; } } Now, I'm gonna bind TestImage to the output of Base64StringToImage method. I've used the following way : public string ImageSource { get; set; } ImageSource = Base64StringToImage("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").Source.ToString(); but nothing happen.

• VSTS 2010 SGEN : error : Could not load file or assembly (Exception from HRESULT: 0x80131515)

  - by Developer IT

  Hi ! I am experiencing a strange issue with VS2010. We use TFS to build our API dlls and we used to reference them in our projects usign a mapped network drive that was fully trusted. We have been working like that for at least two years and everything worked perfectly. Today, I converted a webapp to vs2010 and when I compile it in Release, it's giving me: SGEN : error : Could not load file or assembly 'file:///L:\Api\Release API_20100521.1\Release\CS.API.Exceptions.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) The strange thing is that it's working when it's under the Debug profile... I tried adding the <runtime> <loadFromRemoteSources enabled="true" /> </runtime> into app.config and still no luck (See http://social.msdn.microsoft.com/Forums/en/msbuild/thread/d12f6301-85bf-4b9e-8e34-a06398a60df0 and http://msdn.microsoft.com/en-us/library/dd409252(VS.100).aspx) I am pretty sure that this issue is from visual studio or msbuild, as our code won't run from a network share when in prod because all the referenced dll's are copied into the bin folder. If anyone has an solution (or just an idea for a search path) please let me know !

• Using Visual Studio 2008 to Assemble, Link, Debug, and Execute MASM 6.11 Assembly Code

  - by Kreychek

  I would like to use Visual Studio 2008 to the greatest extent possible while effectively compiling/linking/building/etc code as if all these build processes were being done by the tools provided with MASM 6.11. The exact version of MASM does not matter, so long as it's within the 6.x range, as that is what my college is using to teach 16-bit assembly. I have done some research on the subject and have come to the conclusion that there are several options: Reconfigure VS to call the MASM 6.11 executables with the same flags, etc as MASM 6.11 would natively do. Create intermediary batch file(s) to be called by VS to then invoke the proper commands for MASM's linker, etc. Reconfigure VS's built-in build tools/rules (assembler, linker, etc) to provide an environment identical to the one used by MASM 6.11. Option (2) was brought up when I realized that the options available in VS's "External Tools" interface may be insufficient to correctly invoke MASM's build tools, thus a batch file to interpret VS's strict method of passing arguments might be helpful, as a lot of my learning about how to get this working involved my manually calling ML.exe, LINK.exe, etc from the command prompt. Below are several links that may prove useful in answering my question. Please keep in mind that I have read them all and none are the actual solution. I can only hope my specifying MASM 6.11 doesn't prevent anyone from contributing a perhaps more generalized answer. Similar method used to Option (2), but users on the thread are not contactable: http://www.codeguru.com/forum/archive/index.php/t-284051.html (also, I have my doubts about the necessity of an intermediary batch file) Out of date explanation to my question: http://www.cs.fiu.edu/~downeyt/cop3402/masmaul.html Probably the closest thing I've come to a definitive solution, but refers to a suite of tools from something besides MASM, also uses a batch file: http://www.kipirvine.com/asm/gettingStarted/index.htm#16-bit I apologize if my terminology for the tools used in each step of the code - exe process is off, but since I'm trying to reproduce the entirety of steps in between completion of writing the code and generating an executable, I don't think it matters much.

• External JS usage in FBML - Cannot access external script

  - by santhakr

  Hi, I am trying to create a small facebook app and associate it to a fan page in a tab. I am trying to include an external javascript file in my page and call a method on a button click event. Below is a part of the code <script language="Javascript" src="http://mysite.com/fb.js"></script> <input type="button" value="Click....." onClick="javascript:showDialog();" /> content of fb.js is as below function showDialog() { new Dialog().showMessage('Dialog', 'Button clickeed'); } When I load the tab in my fan page, it shows an error "Cannot allow external script", whereas when I load the canvas url [http://apps.facebook.com/...] directly and click on the button, it works [shows the dialog]. Does script include works only on the canvas and not on the profile page? I have another question though Initially I had the script src as a relative path but it errored out with the same error - "Cannot allow external script". Can't I use relative path for the external scripts?

  First, I'm not a python programmer. I'm an old C dog that's learned new Java and PHP tricks, but python looks like a pretty cool language. I'm getting an error that I can't quite follow.

• ZF2 Zend\Db Insert/Update Using Mysql Expression (Zend\Db\Sql\Expression?)

  - by Aleross

  Is there any way to include MySQL expressions like NOW() in the current build of ZF2 (2.0.0beta4) through Zend\Db and/or TableGateway insert()/update() statements? Here is a related post on the mailing list, though it hasn't been answered: http://zend-framework-community.634137.n4.nabble.com/Zend-Db-Expr-and-Transactions-in-ZF2-Db-td4472944.html It appears that ZF1 used something like: $data = array( 'update_time' => new \Zend\Db\Expr("NOW()") ); And after looking through Zend\Db\Sql\Expression I tried: $data = array( 'update_time' => new \Zend\Db\Sql\Expression("NOW()"), ); But get the following error: Catchable fatal error: Object of class Zend\Db\Sql\Expression could not be converted to string in /var/www/vendor/ZF2/library/Zend/Db/Adapter/Driver/Pdo/Statement.php on line 256 As recommended here: http://zend-framework-community.634137.n4.nabble.com/ZF2-beta3-Zend-Db-Sql-Insert-new-Expression-now-td4536197.html I'm currently just setting the date with PHP code, but I'd rather use the MySQL server as the single source of truth for date/times. $data = array( 'update_time' => date('Y-m-d H:i:s'), ); Thanks, I appreciate any input!

• Using Unit of Work design pattern / NHibernate Sessions in an MVVM WPF

  - by Echiban

  I think I am stuck in the paralysis of analysis. Please help! I currently have a project that Uses NHibernate on SQLite Implements Repository and Unit of Work pattern: http://blogs.hibernatingrhinos.com/nhibernate/archive/2008/04/10/nhibernate-and-the-unit-of-work-pattern.aspx MVVM strategy in a WPF app Unit of Work implementation in my case supports one NHibernate session at a time. I thought at the time that this makes sense; it hides inner workings of NHibernate session from ViewModel. Now, according to Oren Eini (Ayende): http://msdn.microsoft.com/en-us/magazine/ee819139.aspx He convinces the audience that NHibernate sessions should be created / disposed when the view associated with the presenter / viewmodel is disposed. He presents issues why you don't want one session per windows app, nor do you want a session to be created / disposed per transaction. This unfortunately poses a problem because my UI can easily have 10+ view/viewmodels present in an app. He is presenting using a MVP strategy, but does his advice translate to MVVM? Does this mean that I should scrap the unit of work and have viewmodel create NHibernate sessions directly? Should a WPF app only have one working session at a time? If that is true, when should I create / dispose a NHibernate session? And I still haven't considered how NHibernate Stateless sessions fit into all this! My brain is going to explode. Please help!

• Do SEO-friendly URLs really affect a page's ranking?

  - by Lee Harold

  SEO-friendly URLs are all the rage these days. But do they actually have a meaningful impact on a page's ranking in Google and other search engines? If so, why? If not, why not? (Note that I would absolutely agree that SEO-friendly URLs are nicer to use for human beings. My question is whether they actually make a difference to the ranking algorithms.) Update: As it turns out, the Google post that endorphine points to here has caused tremendous confusion in the SEO community. For a sampling of the discussion, see here, here, and here. Part of the problem is that the Google post is addressing the worst case where URL rewriting is done poorly and so you'd be better off sticking with a dynamic URL rather than a mangled static "SEO-friendly" URL. There's no question dynamic URLs can be crawled by Google and can achieve high rankings. Maybe it would be easier to reframe the question more concretely: given 2 otherwise equivalent pages, which will rank higher for the search "do seo friendly urls really affect page ranking"? A) http://stackoverflow.com/questions/505793/do-seo-friendly-urls-really-affect-a-pages-ranking or B) http://stackoverflow.com?question=505793 (a fake URL for comparison only)

• Objective-C SSL Synchronous Connection

  - by Mike

  Hello, I'm a little new to objective-C but have run across a problem that I can't solve, mostly because I'm not sure I am implementing the solution correctly. I am trying to connect using a Synchronous Connection to a https site with a self-signed certificate. I am getting the Error Domain=NSURLErrorDomain Code=-1202 "untrusted server certificate" Error that I have seen some solutions to on this forum. The solution i found was to add: - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace { return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]; } (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge]; } to the NSURLDelegate to accept all certificates. When I connect to the site using just a: NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://examplesite.com/"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; It works fine and I see the challenge being accepted. However when I try to connect using the synchronous connection I still get the error and I don't see the challenge functions being called when I put in logging. How can I get the synchronous connection to use the challenge methods? Is it something to do with the delegate:self part of the URLConnection? I also have logging for sending/receiving data within the NSURLDelegate that is called by my connection function but not by the synchronous function. What I am using for the synchronous part: NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: [NSURL URLWithString:@"https://examplesite.com/"]]; [request setHTTPMethod: @"POST"]; [request setHTTPBody: [[NSString stringWithString:@"username=mike"] dataUsingEncoding: NSUTF8StringEncoding]]; dataReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSLog(@"%@", error); stringReply = [[NSString alloc] initWithData:dataReply encoding:NSUTF8StringEncoding]; NSLog(@"%@", stringReply); [stringReply release]; NSLog(@"Done"); Like I mentioned I'm a little new to objective C so be kind :) Thanks for any help.

• WPF 4.0 Custom panel won't show dynamically added controls in VS 2010 Designer

  - by Matt Ruwe

  I have a custom panel control that I'm trying to dynamically add controls within. When I run the application the static and dynamically added controls show up perfectly, but the dynamic controls do not appear within the visual studio designer. Only the controls placed declaratively in the XAML appear. I'm currently adding the dynamic control in the CreateUIElementCollection override, but I've also tried this in the constructor without success. Public Class CustomPanel1 Inherits Panel Public Sub New() End Sub Protected Overrides Function MeasureOverride(ByVal availableSize As System.Windows.Size) As System.Windows.Size Dim returnValue As New Size(0, 0) For Each child As UIElement In Children child.Measure(availableSize) returnValue.Width = Math.Max(returnValue.Width, child.DesiredSize.Width) returnValue.Height = Math.Max(returnValue.Height, child.DesiredSize.Height) Next returnValue.Width = If(Double.IsPositiveInfinity(availableSize.Width), returnValue.Width, availableSize.Width) returnValue.Height = If(Double.IsPositiveInfinity(availableSize.Height), returnValue.Height, availableSize.Height) Return returnValue End Function Protected Overrides Function ArrangeOverride(ByVal finalSize As System.Windows.Size) As System.Windows.Size Dim currentHeight As Integer For Each child As UIElement In Children child.Arrange(New Rect(0, currentHeight, child.DesiredSize.Width, child.DesiredSize.Height)) currentHeight += child.DesiredSize.Height Next Return finalSize End Function Protected Overrides Function CreateUIElementCollection(ByVal logicalParent As System.Windows.FrameworkElement) As System.Windows.Controls.UIElementCollection Dim returnValue As UIElementCollection = MyBase.CreateUIElementCollection(logicalParent) returnValue.Add(New TextBlock With {.Text = "Hello, World!"}) Return returnValue End Function Protected Overrides Sub OnPropertyChanged(ByVal e As System.Windows.DependencyPropertyChangedEventArgs) MyBase.OnPropertyChanged(e) End Sub End Class And my usage of this custom panel <Window x:Class="MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:CustomPanel" Title="MainWindow" Height="364" Width="434"> <local:CustomPanel1> <CheckBox /> <RadioButton /> </local:CustomPanel1> </Window>

• VS 2010 VSTO Add in for EXCEL 2007 Won't load

  - by Erick

  Hi everyone, We have an application that is built with Excel as the front end using the Office object model. We were using a C++ shim to load it as a COM add in for Excel 2003, but I've updated it to use the latest VSTO for Excel 2007. I've also been using VS 2010 for the latest version. The problem is that everything works great on my dev machine in debugger mode as well as just launching Excel 2007, but I cannot get it to run on any other machine (my current target machine is Win7, development is XP). I've created a ClickOnce deployment of the Addin, and I can see it in the list of COM Addins, but when I check on it to load it nothing happens. I re-open the Addins manager and it is un-checked. I've also tried setting in in the registry, but as soon as I run it, it sets the registry back to do not load. I've tried everything I can think of and searched all over the web but no dice. Any help would be appreciated!

• Java (JSP): repeating the contentType header in a "sub-jsp"

  - by Webinator

  What happens when headers are repeated in a .jsp you include in another .jsp? For example if example.jsp starts with this: <?xml version="1.0" encoding="UTF-8"?> <jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page"> <jsp:directive.page contentType="text/html; charset=UTF-8" /> <div class="content"> <jsp:include page="support-header.jsp"/> ... (it includes support-header.jsp) And then support-header.jsp starts also with this: <?xml version="1.0" encoding="UTF-8"?> <jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/Page"> <jsp:directive.page contentType="text/html; charset=UTF-8" /> ... Is that a problem? Is it bad practice? What does concretely happen when you repeat several times a header that only corresponds to one header in the resulting .html page?

• ExtJS: Combobox in EditorGridPanel not selecting the desired item (with test case)

  - by TomH

  I'm using ExtJS to create an EditorGridPanel with a combobox for an editor in a cell. The combobox in my EditorGridPanel that is not working as I'd expect it to. When the user types the first letter of an item in the drop down list, the combobox seems to ignore it and select the first item in the list. I can reproduce the error consistently and have put together a test case here: http://cluebucket.com/dev/testcase/testcase.html Load the page and reproduce the behavior by the following -- note that this is all done using the keyboard, no mouse clicks: Click 'Add Record' (A new row is added to the grid) enter text in the text field. TAB to the Priority field without selecting anything (None will remain selected) TAB out of the Priority field. (A new row is added to the grid) enter text and TAB to the Priority field TYPE v (Very High is selected) TAB out of the priority field (A new row is added to the grid) enter text and TAB to the Priority field Type v (None is selected, but Very High should have been) TAB out of the priority field Enter text and TAB to the priority field Type l ('el') (Low is selected) TAB out, enter text, TAB to priority Type l (None is selected) It appears that whenever the user attempts to select the same value that was selected in the previous row, the combobox selects None. Any ideas? The code is available at cluebucket.com/dev/testcase/js/testcase.js Thoughts/Pointers/Corrections are appreciated!! thanks tom

• Why doesn't TransactionScope work with Entity Framework?

  - by NotDan

  See the code below. If I initialize more than one entity context, then I get the following exception on the 2nd set of code only. If I comment out the second set it works. {"The underlying provider failed on Open."} Inner: {"Communication with the underlying transaction manager has failed."} Inner: {"Error HRESULT E_FAIL has been returned from a call to a COM component."} Note that this is a sample app and I know it doesn't make sense to create 2 contexts in a row. However, the production code does have reason to create multiple contexts in the same TransactionScope, and this cannot be changed. Edit Here is a previous question of me trying to set up MS-DTC. It seems to be enabled on both the server and the client. I'm not sure if it is set up correctly. Also note that one of the reasons I am trying to do this, is that existing code within the TransactionScope uses ADO.NET and Linq 2 Sql... I would like those to use the same transaction also. (That probably sounds crazy, but I need to make it work if possible). http://stackoverflow.com/questions/794364/how-do-i-use-transactionscope-in-c Solution Windows Firewall was blocking the connections to MS-DTC. using(TransactionScope ts = new System.Transactions.TransactionScope()) { using (DatabaseEntityModel o = new DatabaseEntityModel()) { var v = (from s in o.Advertiser select s).First(); v.AcceptableLength = 1; o.SaveChanges(); } //-> By commenting out this section, it works using (DatabaseEntityModel o = new DatabaseEntityModel()) { //Exception on this next line var v = (from s1 in o.Advertiser select s1).First(); v.AcceptableLength = 1; o.SaveChanges(); } //-> ts.Complete(); }

• Facebook, iframe app, fb:request-form, action attribute problem

  - by Unreality

  Hi all, I'm making a facebook iframe application I'm making a request form with my own form data. What should I do in order to process the data? If I put action="http://apps.facebook.com/[appName]/abc.php" , i.e. <fb:serverfbml> <script type="text/fbml"> <fb:fbml> <fb:request-form action="http://apps.facebook.com/[appName]/abc.php" method="post" type="abc" content="abc"> <textarea name="pm" fb_protected="true" ></textarea> <fb:multi-friend-selector showborder="false" max="35" actiontext="test" email_invite="true" bypass="cancel" /> </fb:request-form> </fb:fbml> </script> </fb:serverfbml> Then the result is funny... A facebook page inside the facebook app's iframe ! but if I put action="http://[my own domain / facebook connect url]/abc.php" , i.e. <fb:serverfbml> <script type="text/fbml"> <fb:fbml> <fb:request-form action="http://[my own domain / facebook connect url]/abc.php" method="post" type="abc" content="abc"> <textarea name="pm" fb_protected="true" ></textarea> <fb:multi-friend-selector showborder="false" max="35" actiontext="test" email_invite="true" bypass="cancel" /> </fb:request-form> </fb:fbml> </script> </fb:serverfbml> Then the result page will be rendered WITHOUT facebook template (that means losing all top facebook banner and bottom facebook bar like the facebook chats etc) Anyone knows what's wrong? Thanks a lot for reading

• ASP.NET MVC in a subfolder (only) on godaddy

  - by Anthony Potts

  Okay, I have read many of the routing posts concerning putting asp.net mvc on godaddy. However, I have not come to a solution to my current problem. I am trying to publish an ASP.NET MVC application to a subfolder on godaddy. I have upgraded the account to use IIS 7 and I have included the MVC dlls in \bin\ deployment method. However, I suspect that my route is not correct. Currently, my routes are set up with the standard out of the box route: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } I have a subdomain set up so that it looks like office.domain.com. The subdomain is pointing at a folder "/office/" which is right off the root folder. (There is not an MVC application installed in the root folder). All of my application has been placed in this 'office' folder. When I hover over the links however, the 'office' portion shows up in the link as well. e.g. Hovering over a link to the customer controller, index action yields "office.domain.com/office/Customer" as the target. This link then gets a 404 when I attempt to go to it. What should my route be to fix this? Is there something I have neglected in setting up the subdomain in godaddy? Is this something I just can't do in godaddy's domain management "tool". Do I need to set up a virtual directory for this instead of just a directory? Update: I changed the IIS settings in godaddy to use integrated pipeline mode, per this discussion and I am no longer getting 404 errors. The application worked just fine as suggested it would.

• Unknown Build Error using WPF Toolkit

  - by Tom Allen

  I installed the Feb 2010 WPF Toolkit as I'm interested in evaluating the AutoCompleteBox control and I'm having extremely limited success. I can get the control to work, but as soon as I try and set any of it's properties in XAML, I get the following: Unknown build error, 'Cannot resolve dependency to assembly 'WPFToolkit, Version=3.5.40128.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event. I've been testing this on a blank WPF window in a new solution. I'm guessing I'm just missing a reference or something... Here's the XAML (I've added nothing to the .xaml.cs): <Window x:Class="WpfToolkitApplication.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:toolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Input.Toolkit" Title="Window1" Height="300" Width="300"> <Grid> <toolkit:AutoCompleteBox Height="25"/> </Grid> </Window> The only reference I've added is System.Windows.Controls.Input.Toolkit. Any ideas?
