  • Missing Edit Option on Silverlight 4 DataForm

    - by rip
    I’m trying out the Silverlight 4 beta DataForm control. I don’t seem to be able to get the edit and paging options at the top of the control like I’ve seen in Silverlight 3 examples. Has something changed or am I doing something wrong? Here’s my code: <UserControl x:Class="SilverlightApplication7.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400" xmlns:dataFormToolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data.DataForm.Toolkit"> <Grid x:Name="LayoutRoot" Background="White"> <dataFormToolkit:DataForm HorizontalAlignment="Left" Margin="10" Name="myDataForm" VerticalAlignment="Top" /> </Grid> </UserControl> public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); this.Loaded += new RoutedEventHandler(MainPage_Loaded); } void MainPage_Loaded(object sender, RoutedEventArgs e) { Movie movie = new Movie(); myDataForm.CurrentItem = movie; } public enum Genres { Comedy, Fantasy, Drama, Thriller } public class Movie { public int MovieID { get; set; } public string Name { get; set; } public int Year { get; set; } public DateTime AddedOn { get; set; } public string Producer { get; set; } public Genres Genre { get; set; } } }

  • UIViewController presentModalViewController: animated: doing nothing?

    - by ryyst
    Hi, I recently started a project, using Apple's Utility Application example project. In the example project, there's an info button that shows an instance of FlipSideView. If you know the Weather.app, you know what the button acts like. I then changed the MainWindow.xib to contain a scrollview in the middle of the window and a page-control view at the bottom of the window (again, like the Weather.app). The scrollview gets filled with instances of MainView. When I then clicked the info button, the FlipSideView would show, but only in the area that was previously filled by the MainView instance – this means that the page-control view on the bottom of the page still showed when the FlipSideView instance got loaded. So, I thought that I would simply add a UIViewController for the top-most window, which is the one declared inside the AppDelegate created along side with the project. So, I created a subclass of UIViewController, put an instance of it inside MainWindow.xib and connected it's view outlet to the UIWindow declared as window inside the app delegate. I also changed the button's action, so that it know sends a message to the MainWindowController instance. The message does get sent (I checked with NSLog() statements), but the FlipSideView doesn't get shown. Here's the relevant (?) code: FlipsideViewController *controller = [[FlipsideViewController alloc] initWithNibName:@"FlipsideView" bundle:nil]; controller.delegate = self; controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; Why's this not working? I've uploaded the entire project here for you to be able to see the whole thing. Thanks for help! -- Ry

  • XamlParseException due to DatePicker from WPFToolKit

I keep getting the following exception. I am getting the exception when I run the application exe from the Release folder. I do not get the exception at all when normally debugging the application in Visual Studio. I have worked out that the exception is because of a DatePicker control I am using - as if I remove the control (build and run the release exe again) the exception goes away. How on earth could I work out what is going wrong here? The datepicker looks so much better but for the effort this looks like it might be to fix I may be incline to switch for a textbox which I validate when the submit button is pressed! Dissapointing...

  • c# WinForms ReportViewer Performance issue using RefreshReport() and ServerReport.SetParameters()

    - by mdk
    Hi All, Currently I am writing a c# client application that uses the WinForms ReportViewer Control to display reports from a remote server. I am having performance troubles with the ReportViewer Control, to be specific with the 2 methods reportViewer.ServerReport.SetParameters() and reportViewer.RefreshReport() – they both take a really long time to complete and not just on the very first call, but on each subsequent call as well. SetParameters() takes 20 to 40 seconds (they vary greatly in time, some execute event okay fast) and RefreshReport() is a bit faster but still takes ages. I don’t think the server is the culprit, as the same report viewed using the browser renders pretty fast, about a second tops. The report in question doesn't matter as well. When I break into the process and take a look at the call stack, I see a call to Socket.DoConnect. So I thought that’s a good reason to start using fiddler and I installed it, disabled caching and fired up the app again to see which call takes that long to connect, but the performance issue was gone. By using a proxy I am having the same performance as the webbrowser. FYI: I am using NTLM authentication in the following way: reportViewer.ServerReport.ReportServerCredentials.NetworkCredentials = new NetworkCredentials() { Username = ... } I don’t have a strong webbackground, so I guess my question is: What should this tell me / What should I be looking into? (Btw: Adding fiddler to my installation package is not the solution I am looking for :)) I am grateful for any pointers. Take care, -Martin

  • 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.

For some reason my server won't start in debug mode in Eclipse so I am having trouble figuring this out.

  • VS 2012 / 2013 AccessViolationException

    - by Goran
    When I run the project (F5) I receive the following exception in IDE: An unhandled exception of type 'System.AccessViolationException' occurred in System.Windows.Forms.dll Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

This is a WPF project, but exception occurs before the App_ctor is executed, so this is external code, and my application code did not start to execute. This happens sporadically, sometimes it happens only once, and sometimes I run the project and get this message for several times in a roll. Then it does not pop up for 5-6 runs, and then starts again. Anyone knows why is this happening? I have just installed clean W8.1 64 bit, VS2013 and TFS 2013 (although I had the same problem with W8 and VS2012, but not as often).

  • WPF - LayoutUpdated event firing repeatedly

    - by Drew Noakes
    I've been adding a bit of animation to my WPF application. Thanks to Dan Crevier's unique solution to animating the children of a panel combined with the awesome WPF Penner animations it turned out to be fairly straightforward to make one of my controls look great and have its children move about with some nice animation. Unfortunately this all comes with a performance overhead. I'm happy to have the performance hit when items are added/removed or the control is resized, but it seems that this perf hit occurs consistently throughout the application's lifetime, even when items are completely static. The PanelLayoutAnimator class uses an attached property to hook the UIElement.LayoutUpdated.aspx) event. When this event fires, render transforms are animated to cause the children to glide to their new positions. Unfortunately it seems that the LayoutUpdated event fires every second or so, even when nothing is happening in the application (at least I don't think my code's doing anything -- the app doesn't have focus and the mouse is steady.) As the reason for the event is not immediately apparent to the event handler, all children of the control have to be reevaluated. This event is being called about once a second when idle. The frequency increases when actually using the app. So my question is, how can I improve the performance here? Any answer that assists would be appreciated, but I'm currently stuck on these sub-questions: What causes the LayoutUpdated event to fire so frequently? Is this supposed to happen, and if not, how can I find out why it's firing and curtail it? Is there a more convenient way within the handler to know whether something has happened that might have moved children? If so, I could bail out early and avoid the overhead of looping each child. For now I will work around this issue by disabling animation when there are more than N children in the panel.

  • How to troubleshoot errors with TeamCity

    - by Tomas Lycken
    I'm following this guide to set up a small environment for source control and automated builds - mostly for learning what it is and how it works, but also for using in those of my hobby projects that I believe will actually be useful some day. However, at the step where he commits and builds, I fail to get a success status in the TeamCity history log. I keep getting the error described in the stack trace below. I have verified with Windows Explorer that the solution file it can't find is actually there, so I really don't know what to do. How do I fix/troubleshoot this?

  • Very slow performance deserializing using datacontractserializer in a Silverlight Application.

    - by caryden
    Here is the situation: Silverlight 3 Application hits an asp.net hosted WCF service to get a list of items to display in a grid. Once the list is brought down to the client it is cached in IsolatedStorage. This is done by using the DataContractSerializer to serialize all of these objects to a stream which is then zipped and then encrypted. When the application is relaunched, it first loads from the cache (reversing the process above) and the deserializes the objects using the DataContractSerializer.ReadObject() method. All of this was working wonderfully under all scenarios until recently with the entire "load from cache" path (decrypt/unzip/deserialize) taking hundreds of milliseconds at most. On some development machines but not all (all machines Windows 7) the deserialize process - that is the call to ReadObject(stream) takes several minutes an seems to lock up the entire machine BUT ONLY WHEN RUNNING IN THE DEBUGGER in VS2008. Running the Debug configuration code outside the debugger has no problem. One thing that seems to look suspicious is that when you turn on stop on Exceptions, you can see that the ReadObject() throws many, many System.FormatException's indicating that a number was not in the correct format. When I turn off "Just My Code" thousands of these get dumped to the screen. None go unhandled. These occur both on the read back from the cache AND on a deserialization at the conclusion of a web service call to get the data from the WCF Service. HOWEVER, these same exceptions occur on my laptop development machine that does not experience the slowness at all. And FWIW, my laptop is really old and my desktop is a 4 core, 6GB RAM beast. Again, no problems unless running under the debugger in VS2008. Anyone else seem this? Any thoughts? Here is the bug report link: https://connect.microsoft.com/VisualStudio/feedback/details/539609/very-slow-performance-deserializing-using-datacontractserializer-in-a-silverlight-application-only-in-debugger

    Hello, I have a problem that i cant solve :( I have a user control (xaml file and cs file) in xaml it's like: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Class="Demo.CtrlContent" x:Name="UserControl" d:DesignWidth="598.333" d:DesignHeight="179.133" xmlns:Demo="clr-namespace:Demo" > <UserControl.Resources> <Storyboard x:Key="SBSmall"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="border" Storyboard.TargetProperty="(FrameworkElement.Width)"> <SplineDoubleKeyFrame KeyTime="00:00:01" Value="I WANT TO BIND VALUE HERE"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </UserControl.Resources> <Border BorderBrush="#FFC2C0C1" CornerRadius="3,3,3,3" BorderThickness="1,1,1,1" RenderTransformOrigin="0.5,0.5" x:Name="border" Margin="1,3,1,3" HorizontalAlignment="Left" VerticalAlignment="Top" Width="300"> and .cs file: public partial class CtrlContent { private mindef W { get { return (mindef) Window.GetWindow(this); } } public double MedWidth { // I WANT BIND THIS VALUE GO TO STORYBOARD VALUE IN XAML ABOVE get { double actualW; if(W == null) actualW = SystemParameters.PrimaryScreenWidth; else actualW = W.WrapMain.ActualWidth; return actualW - border.Margin.Left - border.Margin.Right; } } public double SmlWidth { get { return MedWidth / 2; } } public CtrlContent () { this.InitializeComponent(); } public CtrlContent (Content content) { this.InitializeComponent(); Document = content; } } in my .cs file there's a property called MedWidth, and in XAML file there's a storyboard called: SBSmall I want to bind my storyboard value to my property in class ctrlcontent. *the idea is, the storyboard is an animation to resize the control to a certain width depends on its parent container (the width is dynamic) anybody? please :) thanks!

  • Why doesn't my NamedPipeServerStream wait??

    - by Frank Fella
    I'm working with a NamedPipeServerStream to communicate between two processes. Here is the code where I initialize and connect the pipe: void Foo(IHasData objectProvider) { Stream stream = objectProvider.GetData(); if (stream.Length > 0) { using (NamedPipeServerStream pipeServer = new NamedPipeServerStream("VisualizerPipe", PipeDirection.Out, 1, PipeTransmissionMode.Byte, PipeOptions.Asynchronous)) { string currentDirectory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location); string uiFileName = Path.Combine(currentDirectory, "VisualizerUIApplication.exe"); Process.Start(uiFileName); if(pipeServer.BeginWaitForConnection(PipeConnected, this).AsyncWaitHandle.WaitOne(5000)) { while (stream.CanRead) { pipeServer.WriteByte((byte)stream.ReadByte()); } } else { throw new TimeoutException("Pipe connection to UI process timed out."); } } } } private void PipeConnected(IAsyncResult e) { } But it never seems to wait. I constantly get the following exception: System.InvalidOperationException: Pipe hasn't been connected yet. at System.IO.Pipes.PipeStream.CheckWriteOperations() at System.IO.Pipes.PipeStream.WriteByte(Byte value) at PeachesObjectVisualizer.Visualizer.Show(IDialogVisualizerService windowService, IVisualizerObjectProvider objectProvider) I would think that after the wait returns everything should be ready to go. If I use pipeServer.WaitForConnection() everything works fine, but hanging the application if the pipe doesn't connect is not an option.

  • How to organize SQL script files

    - by Mehper C. Palavuzlar
    We have an Oracle 10g database (a huge one) in our company, and I provide employees with data upon their requests. My problem is, I save almost every SQL query I wrote, and now my list has grown too long. I want to organize and rename these .sql files so that I can find the one I want easily. At the moment, I'm using some folders named as Sales Dept, Field Team, Planning Dept, Special etc. and under those folders there are .sql files like Delivery_sales_1, Delivery_sales_2, ... Sent_sold_lostsales_endpoints, ... Sales_provinces_period, Returnrates_regions_bymonths, ... Jack_1, Steve_1, Steve_2, ... I try to name the files regarding their content but this makes file names longer and does not completely meet my needs. Sometimes someone comes and demands a special report, and I give the file his name, but this is also not so good. I know duplicates or very similar files are growing in time but I don't have control over them. Can you show me the right direction to rename all these files and folders and organize my queries for easy and better control? TIA.

  • Parse.com REST API in Java (NOT Android)

    - by Orange Peel
    I am trying to use the Parse.com REST API in Java. I have gone through the 4 solutions given here https://parse.com/docs/api_libraries and have selected Parse4J. After importing the source into Netbeans, along with importing the following libraries: org.slf4j:slf4j-api:jar:1.6.1 org.apache.httpcomponents:httpclient:jar:4.3.2 org.apache.httpcomponents:httpcore:jar:4.3.1 org.json:json:jar:20131018 commons-codec:commons-codec:jar:1.9 junit:junit:jar:4.11 ch.qos.logback:logback-classic:jar:0.9.28 ch.qos.logback:logback-core:jar:0.9.28 I ran the example code from https://github.com/thiagolocatelli/parse4j Parse.initialize(APP_ID, APP_REST_API_ID); // I replaced these with mine ParseObject gameScore = new ParseObject("GameScore"); gameScore.put("score", 1337); gameScore.put("playerName", "Sean Plott"); gameScore.put("cheatMode", false); gameScore.save(); And I got that it was missing org.apache.commons.logging, so I downloaded that and imported it. Then I ran the code again and got Exception in thread "main" java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;Ljava/lang/Throwable;)V at org.apache.commons.logging.impl.SLF4JLocationAwareLog.debug(SLF4JLocationAwareLog.java:120) at org.apache.http.client.protocol.RequestAddCookies.process(RequestAddCookies.java:122) at org.apache.http.protocol.ImmutableHttpProcessor.process(ImmutableHttpProcessor.java:131) at org.apache.http.impl.execchain.ProtocolExec.execute(ProtocolExec.java:193) at org.apache.http.impl.execchain.RetryExec.execute(RetryExec.java:85) at org.apache.http.impl.execchain.RedirectExec.execute(RedirectExec.java:108) at org.apache.http.impl.client.InternalHttpClient.doExecute(InternalHttpClient.java:186) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:82) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:106) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:57) at org.parse4j.command.ParseCommand.perform(ParseCommand.java:44) at org.parse4j.ParseObject.save(ParseObject.java:450) I could probably fix this with another import, but I suppose then something else would pop up. I tried the other libraries with similar results, missing a bunch of libraries. Has anyone actually used REST API successfully in Java? If so, I would be grateful if you shared which library/s you used and anything else required to get it going successfully. I am using Netbeans. Thanks.

  • Running PowerShell from MSdeploy runcommand does not exit

    - by Peter Moberg
    Im am trying to get MSDeploy to execute a PowerShell script on a remote server. This is how i execute MSDeploy: msdeploy \ -verb:sync \ -source:runCommand='C:\temp\HelloWorld.bat', \ waitInterval=15000,waitAttempts=1 \ -dest:auto,computername=$WebDeployService$Credentials -verbose HelloWorld.bat contains: echo "Hello world!" powershell.exe C:\temp\WebDeploy\Package\HelloWorld.ps1 echo "Done" The HelloWorld.ps1 only contains: Write-Host "Hello world from PowerShell!" However, it seems like PowerShell never terminates. This is the output from running the msdeploy: Verbose: Performing synchronization pass #1.

  • .NET "must-have" development tools

    - by nzpcmad
    James Avery wrote a classic article a while back entitled Ten Must-Have Tools Every Developer Should Download Now which is a companion to Visual Studio Add-Ins Every Developer Should Download Now and Scott Hanselman has an excellent list on his blog but if you were on a desert island and were only allowed three .NET development tools which ones would you pick? Update: Assuming you already have an IDE like Visual Studio ... Update (5) : Up to 08/01 : The current state of play: Reflector 13 Resharper 9 NUnit + TestDriven.Net 7 Refactor Pro 4 Process Explorer (other Sysinternals) 3 SnippetCompiler 3 CodeRush 3 MSDN Library 2 LinqPad 2 Cruisecontrol.net 2 VMWare 2 RhinoMocks 2 Fiddler 2 PowerShell 2 PowerCommands for VS 2008 1 Sandcastle 1 SQL Profiler 1 Redgate ANTS profiler 11 NCover 1 VisualSVN 1 Rubber Ducky 1 WinMerge 1 NAnt 1 ViEmu 1 AnkhSVN 1 dotTrace Profiler 1 BeyondCompare 1 DPack VS Plugin 1 WCF Trace Viewer (SDK) 1 xUnit.net 1 SourceGear DiffMerge 1 Ghostdoc 1 Expression Studio 1 XAML Pad 1 KaXaml 1 Blender for 3D modeling 1 Snoop a WPF tool 1 DiffMerge 1 DPack 1 NDepend 1 Kodos 1 WatiN 1 HTTPWatch Basic Edition 1 Paint.Net 1 Mole For VS 1 What I find particularly interesting about this is that "NUnit + TestDriven.Net " is right up there in third place which shows the growing emphasis on testing as an integral part of the development process rather than as an adjunct which is simply bolted on. And I'm somewhat perplexed that Codesmith didn't receive a single vote?

  • VS 2010 debugger not loading symbols when attaching to NUnit

    - by Dave Hanna
    (I just posted this in the NUnit discussion group on groups.google.com) Under VS 2008, I would run my tests under NUnit, and, if I needed to debug, I would attach the VS2008 debugger to the running Nunit process (Debug - Attach to Process), and set any breakpoints on code I wanted to examine. When I hit the Run buttion in NUnit, it would hit the breakpoint. (BTW, if it matters, this was running NUnit 2.5.2). I just upgraded to NUnit 2.5.4 and VS 2010. When I set a breakpoint, then attach to NUnit, I get a little warning symbol on the breakpoint dot, and hovering over it gives the tooltip "Breakpoint will not be hit. No symbols are currently loaded". Going to the Debug - Windows - Modules window shows a whole bunch of Windows and NUnit modules loaded, with the Symbol Status of "Skipped loading symbols", and then 1 module with a funny name that changes each time (r1euhmh5 right now), and Symbol Status of "No symbols loaded". (There is no trace of a module with a name remotely like my DLL under test). Right clicking the funny filename (assuming that to be some mapping from my DLL under test), and clicking Load Symbols From - Symbol Path, and navigating to the bin\debug folder, then clicking the pdb file of my DLL under test, I get the message "A matching symbol was not found in this folder". (The top of the Open dialog box has a line that says "Original location: r1euhmh5.pdb") So what's changed? And how do I go about debugging/breakpointing under VS 2010/NUnit 2.5.4 (Or is it possible I screwed something up when I decided to go through my VS2010 options and set some of them to more advanced levels than I knew what I was doing?) I appreciate any help.

  • Location of Java dump heap file?

    - by Jim Ferrans
    Well this is embarrassing ... I'm starting to play with the Eclipse Memory Analyzer to look for Java memory leaks on a Windows box. Step 1 is to obtain a heap dump file. To do this< I start my Java (javaw.exe) process from within Eclipse and connect to it with jconsole. Then on the jconsole MBeans tab I click the dumpHeap button. The first time I did this, I saw a pop-up saying it had created the heap dump file, but not giving its name or location. Now whenever I do a dumpHeap again while connected to a different javaw.exe process, jconsole says: Problem invoking dumpHeap : java.io.IOException: File exists and of course doesn't give its name or path. Where could it be? I've searched my C: drive (using cygwin command line tools) for files containing "hprof" or "java_pid" or "heapdump" and didn't find anything plausible. I've even used the Windows search to look for all files in my Eclipse workspace that have changed in the last day. I'm using the Sun Java 1.6 JVM, and don't have -XX:HeapDumpPath set.

  • 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.

  • Exception when creating MailMessage

    - by Julien Poulin
    I'm getting a FormatException telling me the address '[email protected]' is invalid (I'm guessing because of the '-'). Here is the code I'm using: var md = new MailDefinition(); md.BodyFileName = physicalPath; md.Subject = subject; md.From = from; md.CC = cc; md.IsBodyHtml = true; MailMessage mailMessage = md.CreateMailMessage(to, replacements, owner); Is there a bug in the .Net e-mail parser? I am sure this address is valid since it belongs to a friend and I have no problem sending and receiving his e-mails with Outlook. Is there a way to fix this?

  • 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?
