  • How is this Quartz Cron Expression executed

    - by n002213f
    I have a the following; private String cronExpression = ""; private final String jobID = "MyJObID"; ... Scheduler scheduler = ServiceLocator.getInstance().getScheduler(); CronTrigger trigger = new CronTrigger(jobID , Scheduler.DEFAULT_GROUP, cronExpression); JobDetail jobDetail = new JobDetail(jobID , Scheduler.DEFAULT_GROUP, MyJob.class); scheduler.scheduleJob(jobDetail, trigger); My question is when is this job triggered for the empty cron expression?

  • Program and debugger quit without indication of problem

    - by spender
    OK, not quite a Heisenbug but similar in nature. I'm developing a WPF application. When debugging, the logic reaches a certain point, then the application quits for no reason. VS debugger catches nothing and the only indication of a problem is the following in the output window: The program '[6228] SomeApp.vshost.exe: Managed (v4.0.30319)' has exited with code 1073741855 (0x4000001f). When debugging the release version, or indeed running the debug build out of the debugger (in fact all combos that aren't running the debug version in debugger), everything works fine. I'm trying to catch unhandled exceptions with the following code: AppDomain .CurrentDomain .UnhandledException += (sender, e) => { Debug.WriteLine("Unhandled Exception " + e.ExceptionObject); }; Application .Current .DispatcherUnhandledException += (sender1, e1) => { Debug.WriteLine("DispatcherUnhandledException " + e1.Exception); }; ...but I'm not catching anything. I'm considering peppering the app with debug output statements, but it's highly asynchronous so reading this will be both arduous and tedious. So tell me, if you can... how do I start figuring WTF is going on?

  • JavaScript variable to ColdFusion variable

    - by Alexander
    I have a tricky one. By means of a <cfoutput query="…"> I list some records in the page from a SQL Server database. By the end of each line viewing I try to add this in to a record in a MySQL database. As you see is simple, because I can use the exact variables from the output query in to my new INSERT INTO statement. BUT: the rsPick.name comes from a database with a different character set and the only way to get it right into my new database is to read it from the web page and not from the value came in the output query. So I read this value with that little JavaScript I made and put it in the myValue variable and then I want ColdFusion to read that variable in order to place it in my SQL statement. <cfoutput query="rsPick"> <tr> <td>#rsPick.ABBREVIATION#</td> <td id="square"> #rsPick.name# </td> <td>#rsPick.Composition#</td> <td> Transaction done... <script type="text/javascript"> var myvalue = document.getElementById("square").innerHTML </script> </td> <cfquery datasource="#Request.Order#"> INSERT INTO products (iniid, abbreviation, clsid, cllid, dfsid, dflid, szsid, szlid, gross, retail, netvaluebc, composition, name) VALUES ( #rsPick.ID#, '#rsPick.ABBREVIATION#', #rsPick.CLSID#, #rsPick.CLLID#, #rsPick.DFSID#, #rsPick.DFLID#, #rsPick.SZSID#, #rsPick.SZLID#, #rsPick.GROSSPRICE#, #rsPick.RETAILPRICE#, #rsPick.NETVALUEBC#, '#rsPick.COMPOSITION#','#MYVALUE#' ) </cfquery> </tr> </cfoutput>

  • Extract a subset of XML file using XSL

    - by Lucas -luky- Noleto
    I have this XML file: <Response> <errorCode>error Code</errorCode> <errorMessage>msg</errorMessage> <ResponseParameters> <className> <attribute1>a</attribute1> <attribute2>b</attribute2> </className> </ResponseParameters> </Response> And I want the output to be: <className> <attribute1>a</attribute1> <attribute2>b</attribute2> </className> My current XSL file is including also "ResponseParameters" tag, which I do not want. EDIT: note that the node className is dynamic. I do not know what will be this name at runtime. <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output indent="yes" /> <xsl:template match="/"> <xsl:copy-of select="//ResponseParameters"> </xsl:copy-of> </xsl:template> </xsl:stylesheet>

  • Ruby on Rails: Using XML Builder Partials

    - by randombits
    Partials in XML builder are proving to be non-trivial. After some initial Google searching, I found the following to work, although it's not 100% xml.foo do xml.id(foo.id) xml.created_at(foo.created_at) xml.last_updated(foo.updated_at) foo.bars.each do |bar| xml << render(:partial => 'bar/_bar', :locals => { :bar => bar }) end end this will do the trick, except the XML output is not properly indented. the output looks something similar to: <foo> <id>1</id> <created_at>sometime</created_at> <last_updated>sometime</last_updated> <bar> ... </bar> <bar> ... </bar> </foo> The <bar> element should align underneath the <last_updated> element, it is a child of <foo> like this: <foo> <id>1</id> <created_at>sometime</created_at> <last_updated>sometime</last_updated> <bar> ... </bar> <bar> ... </bar> </foo> Works great if I copy the content from bar/_bar.xml.builder into the template, but then things just aren't DRY.

  • Writing tests for Rails plugins

    - by Adam
    I'm working on a plugin for Rails that would add limited in-memory caching to ActiveRecord's finders. The functionality itself is mature enough, but I can't for the life of me get unit tests to work with the plugin. I now have under vendor/plugins/my_plugin/test/my_plugin_test.rb a standard subclass of ActiveSupport::TestCase with a couple of basic tests. I try running 'rake test' from the plugin directory, and I have confirmed that this task loads the ruby file with the test case, but it doesn't actually run any of the tests. I followed the Rails plugin guide (http://guides.rubyonrails.org/plugins.html) where applicable, but it seems to be horribly outdated (it suggests things that Rails now do automatically, etc.) The only output I get is this: Kakadu:ingenious_record adam$ rake test (in /Users/adam/Sites/1_PRK/vendor/plugins/ingenious_record) /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -Ilib:lib:test "/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rake-0.8.3/lib/rake/rake_test_loader.rb" "test/ingenious_record_test.rb" The simplest test case looks like this: require 'test_helper' require 'active_record' class IngeniousRecordTest < ActiveSupport::TestCase test "example" do assert false end end This should definitely produce at least some output, and the only test in that file should produce a failed assertion. Any ideas what I could do to get Rails to run my tests?

  • How to propertly reference a namespace for Microsoft.Sdc.Tasks.XmlFile.GetValue

    - by æther
    Hi, i want to use MSBuild to insert a custom xml element into web.config. After looking up online, i found such solution: 1) Store element in the .build file in projectextensions <ProjectExtensions> <CustomElement name="CustomElementName"> ... </CustomElement> </ProjectExtensions> 2) Retrieve the element with GetValue <Target name="ModifyConfig"> <XmlFile.GetValue Path="$(MSBuildProjectFullPath)" XPath="Project/ProjectExtensions/CustomElement[@name='CustomElementName']"> <Output TaskParameter="Value" PropertyName="CustomElementProperty"/> </XmlFile.GetValue> </Target> This will not work as i need to reference a namespace the .build project is using for it to find the needed element (checked the .build file with XPath Visualizer). So, i look up for a further solution and come to this: <ItemGroup> <XmlNamespace Include="MSBuild"> <Prefix>msb</Prefix> <Uri>http://schemas.microsoft.com/developer/msbuild/2003</Uri> </XmlNamespace> </ItemGroup> <Target name="ModifyConfig"> <XmlFile.GetValue Path="$(MSBuildProjectFullPath)" Namespaces="$(XmlNamespace)" XPath="/msb:Project/msb:ProjectExtensions/msb:CustomElement[@name='CustomElementName']" > <Output TaskParameter="Value" PropertyName="CustomElementProperty"/> </XmlFile.GetValue> </Target> But for some reason namespace is not recognized - MSBuild reports the following error: C:...\mybuild.build(53,9): error : A task error has occured. C:...\mybuild.build(53,9): error : Message = Namespace prefix 'msb' is not defined. I tried some variations of referencing it differently but none work, and there is not much about propertly referencing those namespaces online also. Can you tell me what am i doing wrong and how to do it propertly?

  • Switch to tab by typing a substring of its name in Visual Studio 2005

    - by Vineus
    Is there a way to navigate between tabs in VS similar to the emacs iswtichb-mode or Firefox ubiquity switch tab mode (https://wiki.mozilla.org/Labs/Ubiquity/Ubiquity_0.1_Author_Tutorial#Switching_Tabs) ? In these apps, you just type a substring of the title of the tab (or buffer for emacs) to switch to this tab. For instance, to switch to a tab named "App_Code/Data/MyProgram.cs", you just invoke the tab switching command and then type "Progr" for instance to list all the tab whose name matches this string, including "MyProgram.cs". It's much easier to switch between tabs this way when you have a lot of documents open and when you now where to go (which is the case in most situation) Thank you !

  • Loop OpenAL source with offset

    - by ressaw
    The OpenAL API states that an setting an offset still causes the sound to loop back to zero for looping sources. But is there a way to loop and still have an offset somehow? I have an mp3, and since it contains headers with information at the start of the file, there's a small, but noticable, delay in looping when it rewinds. If not, are there any other compressed formats that don't contain these empty headers?

  • OpenGL ES Simple Undo Last Drawing

    - by Erika
    Hi Everyone, I am trying to figure out how to implement a simple "undo" of last drawing action on the iPhone screen. I draw by first preparing the frame buffer: [EAGLContext setCurrentContext:context]; glBindFramebufferOES(GL_FRAMEBUFFER_OES, viewFramebuffer); I then prepare the vertex array and draw this way: glVertexPointer(2, GL_FLOAT, 0, vertexBuffer); glDrawArrays(GL_POINTS, 0, vertexCount); glBindRenderbufferOES(GL_RENDERBUFFER_OES, viewRenderbuffer); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; How do I simple undo this last action? There has to be a way to save previous state or an built-in OpenGL ES function, I would think. Thanks

  • How to get around batch file processing limit

    - by Patrick Cuff
    I have a Windows batch file that processes all the files in a given directory. I have 206,783 files I need to process: for %%f in (*.xml) do call :PROCESS %%f goto :STOP :PROCESS :: do something with the file program.exe %1 > %1.new set /a COUNTER=%COUNTER%+1 goto :EOF :STOP @echo %COUNTER% files processed When I run the batch file, the following output is written: 65535 files processed As part of the processing, an output file is created for each file procesed, with a .new extension. When I do a dir *.new it reports 65,535 files exist. So, it appears my command environment has a hard limit on the number of files it can recognize, and that limit is 64K - 1. Is there a way to extend the command environment to manage more than 64K - 1 files? If not, would a VBScript or JavaScript be able to process all 206,783 files? I'm running on Windows 2003 server, Enterprise Edition, 32-bit. UPDATE It looks like the root cause of my issue was with the built-in Windows "extract" command for ZIP files. The files I have to process were copied from another system via a ZIP file. My server doesn't have a ZIP utility installed, just the native Windows commands. I right-clicked on the ZIP file, and did an "Extract all...", which apparently just extracted the first 65,535 files. I downloaded and installed 7-zip onto my server, unzipped all the files, and my batch script worked as intended.

  • drawTextInRect on UITextField not called

    - by subw
    I'm trying to implement the answer to this SO question. The problem is: -[drawTextInRect] is apparently not called, and setting the shadow in -[drawRect] doesn't make the UITextField's text shadowed. Another weird thing is that even if my subclass implementations of -[drawTextInRect] and -[drawRect] are completely empty (not even a call to super), the textfield's text is drawn.

  • Form submit to target iframe only works once

    - by Pointy
    I'm having a really irritating problem doing something that I'm sure I've done before. The setup is this: There's a form which is submitted via a "click" handler on a button, though the submit is ultimately a simple call to the form's native submit() function. The form's target is an iframe, which is initially filled with an empty page (that is, its source object is an URL for an empty page). That is, the "target" attribute of the form is the same identifier (and yes, it's a valid identifier) as the "name" and "id" attributes of the iframe (and yes, it's unique) Now the goal of this setup is as follows: the form contains file upload fields. Should something be wrong with one of the files uploaded, the server will report back an error. If the error response (that is, the html page with a new copy of the form, along with appropriate error messages) were to be allowed to reload the original window, then the file input fields would be cleared. That's not good. Thus the form submits to the iframe, so that the response from the server can be a small page that knows it's in that hidden iframe, and knows to move the error messages up to the form. One more thing: the form itself is also in an iframe, as part of a popup modal dialog (like a jQuery UI dialog, only slightly different; same idea though). The setup works fine - on the first submit. In other words, if I supply nice happy files to upload, the server ships back the successful response, and the dialog is closed correctly. If I send a bogus file, the server responds with an error page that correctly copies its stuff up to the form page. On the second submit, however (like, if I fix the bogus file input field), the browser insists on sending the server response to a new browser tab. As far as I can tell, the form's "target" remains correct, the iframe "name" and "id" attributes aren't changed, and I even make sure to update the hidden iframe "window.name" and "window.id" values. None of that is helping; I always get a new browser tab. I'm trying to set up a slightly simpler test case to see if I can rule out some of my framework code (the stuff that does the submit), though via a few console.log() calls I think that stuff is OK; it's certainly OK on all the other dialogs etc. in the site. When/if I create a simpler version I'll post it. In the meantime, if any of you insanely smart people recognize this situation and know of a trick to make it work, I'd be really thankful. I see the same behavior in both Firefox (3.6) and Chrome, so it's got to be my problem and not a browser quirk (well, at least that's what I think to be true).

  • Delphi SAPI Text-To-Speech

    - by Andreas Rejbrand
    First of all: this is not a duplicate of http://stackoverflow.com/questions/1021490/delphi-and-sapi. I have a specific problem with the "SAPI in Delphi" subject. I have used the excellent Import Type-Library guide in Delphi 2009 to get a TSpVoice component in the component palette. This works great. With var SpVoice: TSpVoice; I can write SpVoice.Speak('This is an example.', 1); to get asynchronous audio output. First question According to the documentation, I would be able to write SpVoice.Speak('This is an example.', 0); to get synchronous audio output, but instead I get an EZeroDivide exception. Why's that? Second question But more importantly, I would like to be able to create the SpVoice object dynamically (I think this is called to "late-bound" the SpVoice object), partly because only a very small fraction of all sessions of my app will use it, and partly because I do not want to assume the existance of the SAPI server on the end-user's system. To this end, I tried procedure TForm1.FormClick(Sender: TObject); var SpVoice: Variant; begin SpVoice := CreateOleObject('SAPI.SpVoice'); SpVoice.Speak('this is a test', 0); end; which apparently does nothing at all! (Replacing the 0 with 1 gives me the EZeroDivide exception.) Disclaimer I am rather new to COM/OLE automation. I am sorry for any ignorance or stupidity shown by me in this post...

  • SMO restore of SQL database doesn't overwrite

    - by Tom H.
    I'm trying to restore a database from a backup file using SMO. If the database does not already exist then it works fine. However, if the database already exists then I get no errors, but the database is not overwritten. The "restore" process still takes just as long, so it looks like it's working and doing a restore, but in the end the database has not changed. I'm doing this in Powershell using SMO. The code is a bit long, but I've included it below. You'll notice that I do set $restore.ReplaceDatabase = $true. Also, I use a try-catch block and report on any errors (I hope), but none are returned. Any obvious mistakes? Is it possible that I'm not reporting some error and it's being hidden from me? Thanks for any help or advice that you can give! function Invoke-SqlRestore { param( [string]$backup_file_name, [string]$server_name, [string]$database_name, [switch]$norecovery=$false ) # Get a new connection to the server [Microsoft.SqlServer.Management.Smo.Server]$server = New-SMOconnection -server_name $server_name Write-Host "Starting restore to $database_name on $server_name."

  • C#: How to set AsyncWaitHandle in Compact Framework?

    - by Thorsten Dittmar
    Hi, I'm using a TcpClient in one of my Compact Framework 2.0 applications. I want to receive some information from a TCP server. As the Compact Framework does not support the timeout mechanisms of the "large" framework, I'm trying to implement my own timeout-thing. Basically, I want to do the following: IAsyncResult result = client.BeginRead(buffer, 0, size, ..., stream); if (!result.AsyncWaitHandle.WaitOne(5000, false)) // Handle timeout private void ReceiveFinished(IAsyncResult ar) { NetworkStream stream = (NetworkStream)ar.AsyncState; int numBytes = stream.EndRead(ar); // SIGNAL IASYNCRESULT.ASYNCWAITHANDLE HERE ... HOW?? } I'd like to call Set for the IAsyncResult.AsyncWaitHandle, but it doesn't have such a method and I don't know which implementation to cast it to. How do I set the wait handle? Or is it automatically set by calling EndRead? The documentation suggests that I'd have to call Set myself... Thanks for any help!

  • Median Filter a bi-level image with JAI

    - by Mark
    I'd like to apply a Median Filter to a bi-level image and output a bi-level image. The JAI median filter seems to output an RGB image, which I'm having trouble downconverting back to bi-level. Currently I can't even get the image back into gray color-space, my code looks like this: BufferedImage src; // contains a bi-level image ParameterBlock pb = new ParameterBlock(); pb.addSource(src); pb.add(MedianFilterDescriptor.MEDIAN_MASK_SQUARE); pb.add(3); RenderedOp result = JAI.create("MedianFilter", pb); ParameterBlock pb2 = new ParameterBlock(); pb2.addSource(result); pb2.add(new double[][]{{0.33, 0.34, 0.33, 0}}); RenderedOp grayResult = JAI.create("BandCombine", pb2); BufferedImage foo = grayResult.getAsBufferedImage(); This code hangs on the grayResult line and appears not to return. I assume that I'll eventually need to call the "Binarize" operation in JAI. Edit: Actually, the code appears to be stalling once I call getAsBufferedImage(), but returns nearly instantly when the second operation ("BandCombine") is removed. Is there a better way to keep the Median Filtering in the source color domain? If not, how do I downconvert back to binary?

  • Passing parameters between interrupt handlers on a Cortex-M3 ...

    - by Captain NedD
    I'm building a light kernel for a Cortex-M3. From a high priority interrupt I'd like to invoke some code to run in a lower priority interrupt and pass some parameters along. I don't want to use a queue to post work to the lower priority interrupt. I just have a buffer and size to pass to it. In the proramming manual it says that the SVC interrupt handler is synchronous which presumably means that if you invoke it from an interrupt that's a lower priority than SVC's handler it gets called immediately (the upshot of this being that you can pass parameters to it as though it were a function call (a little like the BIOS calls in MS-DOS)). I'd like to do it the other way: passing parameters from a high priority interrupt to a lower priority one (at the moment I'm doing it by leaving the parameters in a fixed location in memory). What's the best way to do this (if at all possible)? Thanks,
