  • How to add deploy.jar to classpath?

    - by dma_k
    I am facing the problem: I need to add ${java.home}/lib/deploy.jar JAR file to classpath in the runtime (dynamically from java). The solution with Thread#setContextClassLoader(ClassLoader) (mentioned here) does not work because of this bug (if somebody can explain what is really a problem – you are welcome). The solution with -Xbootclasspath/a:"%JAVA_HOME%/jre/lib/deploy.jar" does not work well for me, because I want to have "pure executable jar" as a deliverable: no wrapping scripts please (more over %JAVA_HOME% may not be defined in user's environment in Windows for example, plus I need to write a script per platform) The solution with merging deploy.jar file into my deliverable works only if I make a build on Windows platform. Unfortunately, when the deliverable is produced on build server running on Linux, I got Linux-dependant JAR, which does not execute on Windows – it fails with the trace below. I have read How the Java Launcher Finds Classes and Java programming dynamics: Java classes and class loading articles but I've got no extra ideas, how to correctly handle this situation. Any advices or solutions are very welcomed. Trace: java.lang.NoClassDefFoundError: Could not initialize class com.sun.deploy.config.Config at com.sun.deploy.net.proxy.UserDefinedProxyConfig.getBrowserProxyInfo(UserDefinedProxyConfig.java:43) at com.sun.deploy.net.proxy.DynamicProxyManager.reset(DynamicProxyManager.java:235) at com.sun.deploy.net.proxy.DeployProxySelector.reset(DeployProxySelector.java:59) ... java.lang.NullPointerException at com.sun.deploy.net.proxy.DynamicProxyManager.getProxyList(DynamicProxyManager.java:63) at com.sun.deploy.net.proxy.DeployProxySelector.select(DeployProxySelector.java:166)

  • Jquery UI Datepicker disabling wrong days

    - by Nazariy
    I have run in to issue that days that have to be disabled are shifted to the next day. The idea is that day that does not exist in our booking object or have a value less than 1 should be disabled on calendar. here is simplified version of my script and demonstration on jsfiddle: var bookings = { "2012-09-01": 24, "2012-09-03": 31, "2012-09-05": 27, "2012-09-06": 9, "2012-09-07": 18, "2012-09-08": 0, "2012-09-10": 20, "2012-09-12": 19, "2012-09-13": 0, "2012-09-14": 9, "2012-09-15": 24, "2012-09-17": 19, "2012-09-19": 28, "2012-09-20": 15, "2012-09-21": 12, "2012-09-22": 25, "2012-09-24": 19, "2012-09-26": 0, "2012-09-27": 0, "2012-09-28": 0, "2012-09-29": 0 }; function MyEvent(date) { bookings = bookings || {}; this.date = date.toISOString().substr(0, 10); this.display = (typeof bookings[this.date] == 'number' && bookings[this.date] > 0); return this; } MyEvent.prototype.toArray = function () { return [this.display, null, null]; }; $(function () { $('#eventCalendar').datepicker({ dateFormat: "yy-mm-dd", firstDay: 1, defaultDate: "2012-09-24", beforeShowDay: function (date) { return new MyEvent(date).toArray(); } } ); }); Can some one suggest me what am I doing wrong or is it a bug?

  • Download dynaic file with GWT

    - by Maksim
    I have a GWT page where user enter data (start date, end date, etc.), then this data goes to the server via RPC call. On the server I want to generate Excel report with POI and let user save that file on their local machine. This is my test code to stream file back to the client but for some reason it does not know: public class ReportsServiceImpl extends RemoteServiceServlet implements ReportsService { public String myMethod(String s) { File f = new File("/excelTestFile.xls"); String filename = f.getName(); int length = 0; try { HttpServletResponse resp = getThreadLocalResponse(); ServletOutputStream op = resp.getOutputStream(); ServletContext context = getServletConfig().getServletContext(); resp.setContentType("application/octet-stream"); resp.setContentLength((int) f.length()); resp.setHeader("Content-Disposition", "attachment; filename*=\"utf-8''" + filename + ""); byte[] bbuf = new byte[1024]; DataInputStream in = new DataInputStream(new FileInputStream(f)); while ((in != null) && ((length = in.read(bbuf)) != -1)) { op.write(bbuf, 0, length); } in.close(); op.flush(); op.close(); } catch (Exception ex) { ex.printStackTrace(); } return "Server says: " + filename; } } I've red somewhere on internet that you can't do file stream with RPC and I have to use Servlet for that. Is there any example of how to use Servlet and how to call that servlet from ReportsServiceImpl

  • How to have an iCalendar (RFC 2445) repeat YEARLY with duration

    - by Todd Brooks
    I have been unsuccessful in formulating a RRULE that would allow an event as shown below: Repeats YEARLY, from first Sunday of April to last day of May, occuring on Monday, Wednesday and Friday, until forever. FREQ=YEARLY;BYMONTH=4;BYDAY=SU (gives me the first Sunday of April repeating yearly) and FREQ=YEARLY;BYMONTH=5;BYMONTHDAY=-1 (gives me the last day of May repeating yearly) But I can't figure out how to have the event repeat yearly between those dates for Monday, Wednesday and Friday. Suggestions? Update: Comments don't have enough space to respond to Chris' answer, so I am editing the question with further information. Unfortunately, no. I don't know if it is the DDay.iCal library I'm using, or what, but that doesn't work either. I've found that the date start can't be an ordinal date (first Sunday, etc.)..it has to be a specific date, which makes it difficult for my requirements. Even using multiple RRULE's it doesn't seem to work: BEGIN:VCALENDAR VERSION:2.0 PRODID:-//DDay.iCal//NONSGML ddaysoftware.com//EN BEGIN:VEVENT CREATED:20090717T033307Z DTSTAMP:20090717T033307Z DTSTART:20090101T000000 RRULE:FREQ=YEARLY;WKST=SU;BYDAY=MO,WE,FR;BYMONTH=4,5 RRULE:FREQ=YEARLY;WKST=SU;BYDAY=1SU;BYMONTH=4 RRULE:FREQ=YEARLY;WKST=SU;BYMONTH=5;BYMONTHDAY=-1 SEQUENCE:0 UID:352ed9d4-04d0-4f06-a094-fab7165e5c74 END:VEVENT END:VCALENDAR That looks right on the face (I'm even starting the event on 1/1/2009), but when I start testing whether certain days are valid, I get incorrect results. For example, 4/1/2009 12:00:00 AM = True // Should be False 4/6/2009 12:00:00 AM = True 4/7/2009 12:00:00 AM = False 4/8/2009 12:00:00 AM = True 5/1/2009 12:00:00 AM = True 5/2/2009 12:00:00 AM = False 5/29/2009 12:00:00 AM = True 5/31/2009 12:00:00 AM = True // Should be False 6/1/2009 12:00:00 AM = False I'm using Douglas Day's DDay.iCal software, but I don't think it is a bug in that library. I think this might be a limitation in iCalendar (RFC 2445). Thoughts?

  • Forces to prompt download box IE

    - by Bruno Costa
    Hello, I'm having a problem with some reports in the application I'm doing manutention I've a button that does a postback to the server and do some information and then get back to the cliente and open a popup to download the report. private void grid_ItemCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e) { ...

But by default this is disabled and I need to force the download box to be prompting. Can I do anything without change a lot of code? Thanks.

  • Problems solving oddly acting labels in ie7.

    - by Qwibble
    Okay so this is sort of a double question so I'll split it into two. First part In modern browsers the main bold labels sit above their corresponding form elements, and align to the left as is expected. However in ie7, they randomly site 10-15px inset. I went through the developer tools and could find nothing to fix it. I've made sure all my margins and padding is reset so I don't really understand =S Here's the page demo - link Maybe some of you ie bug fixing genius's know what the problem is? =D Second part Again with labels, this time the in-line ones resident next to the check boxes and radio buttons. In modern browsers again, the side beside the form elements as expected, but not so in ie7 where they take a new line. I've tried floating, changing margins and everything but to no effect in sitting it in-line with the div.checker or div.radio that is created by the uniform Jquery plugin. Here's the page demo - link Sorry for troubling you with my ie7 problems, I know they arent the most fun to solve. Hopefully someone has the patience to help. Matt

  • Is there unreachable code in this snippet? I don't think so, but Resharper is telling me otherwise.

    - by The Matt
    I have the following method I came across in a code review. Inside the loop Resharper is telling me that if (narrativefound == false) is incorrect becuase narrativeFound is always true. I don't think this is the case, because in order to set narrativeFound to true it has to pass the conditional string compare first, so how can it always be true? Am I missing something? Is this a bug in Resharper or in our code? public Chassis GetChassisForElcomp(SPPA.Domain.ChassisData.Chassis asMaintained, SPPA.Domain.ChassisData.Chassis newChassis) { Chassis c = asMaintained; List<Narrative> newNarrativeList = new List<Narrative>(); foreach (Narrative newNarrative in newChassis.Narratives) { bool narrativefound = false; foreach (Narrative orig in asMaintained.Narratives) { if (string.Compare(orig.PCode, newNarrative.PCode) ==0 ) { narrativefound = true; if (newNarrative.NarrativeValue.Trim().Length != 0) { orig.NarrativeValue = newNarrative.NarrativeValue; newNarrativeList.Add(orig); } break; } if (narrativefound == false) { newNarrativeList.Add(newNarrative); } } } c.SalesCodes = newChassis.SalesCodes; c.Narratives = newNarrativeList; return c; }

  • I did my own web framework: now, how keep it sync with applications? must I use versions?

    - by Daniel Koch
    ... and I did the first web application using it, now I'm going to create the second. In this first web application I enhanced the framework's core library with new things and promptly updated framework branch. I'm using bazaar to keep framework and web application committed. The application was in the beginning, a full branch of framework source tree, now I'm updating framework manually at every change on core files. (copying changed files from web app to framework's branch). With this second web application that I'm going to create, I need to know about versions (or revisions) which the application is based. If I found a bug in this version I can fix and then sync files with first web application no worrying: functions will be the same to this application. If I'm going to make changes in core (new behavior, new functions in library or something new in source tree) it must be named as "new version". What's the best way to do this? Because I'm using a Distributed Version Control System (bazaar), I'm not dealing with VERSIONS, but revision numbers that change every time. Please fresh my mind with new ideas.

  • Rails 3 Timezone error

    - by Juan
    I am struggling with time zone support in Rails 3 beta and I would like to know if it is a bug or if I am doing something wrong. He is the problem: > Time.zone = 'Madrid' # it is GMT+2 = "Madrid" > c = Comment.new = #<Comment id: nil, title: "", pub_at: nil> > c.pub_at = Time.zone.parse('10:00:00') = Mon, 31 May 2010 10:00:00 CEST +02:00 > c.save > c = #<Comment id: 3, title: "", pub_at: "2010-05-31 08:00:00"> > c.reload = #<Comment id: 3, title: "", pub_at: "2010-05-31 08:00:00"> ruby-1.8.7-p249 c.pub_at = Mon, 31 May 2010 13:00:00 CEST +02:00 As you can see, the pub_at attribute is stored correctly in the database but when it is retrieved it adds 3 hours and I suspect that it is because it is using my local machine timezone that is in GMT-3. The same sequence of commands in rails 2.3.5 works perfectly. Any toughts? Should I report a ticket?

  • GWT RPC and GoDaddy Shared Hosting

    - by Mike Apolis
    Hi, I've deployed the sample Stock Watcher app to my GoDaddy Hosting site, and I get the error below. I've tried compiling the Project in Eclipse with JRE 1.5 because my Host is using jre 1.5. I think the issue is the "gwt-servlet.jar" is not compatible with jre 1.5. Can anyone confirm this. The project runs fine on my local machine using JRE 1.6. Unfortunately GoDaddy will not upgrade my shared hosting account jre to 1.6.

  • Start dependent application with eunit

    I start lager as a dependent application when I run a unit test but for some reason the code under test does not see it. -module(main_tests). -include_lib("eunit/include/eunit.hrl"). main_test_() -> {foreach, fun distr_setup/0, fun distr_cleanup/1, [ fun must_retain/1 ]}. must_retain(_) -> {"Should do ping pong when is fully initialized", fun() -> ?assertEqual(pong, abuse_counter:ping()) end}. %%------------------------------------------------------------------ distr_setup() -> abuse_counter:start_link(), ok. distr_cleanup(_) -> abuse_counter:stop(), ok.

  • How to close all tabs in Safari using AppleScript?

    - by Form
    I have made a very simple AppleScript to close all tabs in Safari. The problem is, it works, but not completely. Here's the code: tell application "Safari" repeat with aWindow in windows repeat with aTab in tabs of aWindow aTab close end repeat end repeat end tell I've also tried this script: tell application "Safari" repeat with i from 0 to the number of items in windows set aWindow to item i of windows repeat with j from 0 to the number of tabs in aWindow set aTab to item j of tabs of aWindow aTab close end repeat end repeat end tell ... but it does not work either. I tried that on my system (MacBook Pro jan 2008), as well as on a Mac Pro G5 under Tiger and the script fails on both, albeit with a much less descriptive error on Tiger. The problem is that only a couple of tabs are closed. Running the script a few times closes a few tab each time until none is left, but always fails with the same error after closing a few tabs. Under Leopard I get an out of bounds error. Since I am using fast enumeration (not using "repeat from 0 to number of items in windows") I don't see how I can get an out of bounds error with this... My goal is to use the Cocoa Scripting Bridge to close tabs in Safari from my Objective-C Cocoa application but the Scripting Bridge fails in the same manner. The non-deletable tabs show as NULL in the Xcode debugger, while the other tabs are valid objects from which I can get values back (such as their title). In fact I tried with the Scripting Bridge first then told myself why not try this directly in AppleScript and I was surprised to see the same results. I must have a glaring omission or something in there... (seems like a bug in Safari AppleScript support to me... :S) I've used repeat loops and Obj-C 2.0 fast enumeration to iterate through collections before with zero problems, so I really don't see what's wrong here. Anyone can help? Thanks in advance!

  • IKImageView, Buttons work intermittently in 10.5 but ok in 10.6

    - by markhunte
    Hi all, In IB,I have connected some buttons to a IKImageView. Using its received Action 'ZoomIn:', 'ZoomOut:','ZoomImageToActualSize:' When I build for 10.6 I have no issues these work as expected. But in 10.5 (ppc), they sometimes work as expected and sometimes do not. I have even tried it programatically. But I get the same results. It is intermittent with each build after I have made some small change in IB that I need. But not changes that should affect how the view acts. The only buttons that seem to work through out are 'ZoomImageToFit' and the rotate ones. When the do not work as expected, I see no change to the current image in the view, but when my app (/s, I have had this issue before in different apps) changes the image The view reflects the last request from a button. So for example when it does not work. An image is displayed, I click the 'ZoomImageToActualSize:' button, nothing happens. I load a new image and it is displayed at Actual size. Example when it does work. An image is displayed, I click the 'ZoomImageToActualSize:' button, It is displayed at Actual size. By the way, I know I can reset the view default , before I load a new image. Also if I run the 10.5 app in 10.6, it works ok, but as above I get intermittent results with the same build on multible 10.5 machines. Does anyone know what is going on, is this a known bug? Thanks for any help. MH

  • Diffrernce between BackgroundWorker.ReportProgress() and Control.Invoke()

    - by ohadsc
    What is the difference between options 1 and 2 in the following? private void BGW_DoWork(object sender, DoWorkEventArgs e) { for (int i=1; i<=100; i++) { string txt = i.ToString(); if (Test_Check.Checked) //OPTION 1 Test_BackgroundWorker.ReportProgress(i, txt); else //OPTION 2 this.Invoke((Action<int, string>)UpdateGUI, new object[] {i, txt}); } } private void BGW_ProgressChanged(object sender, ProgressChangedEventArgs e) { UpdateGUI(e.ProgressPercentage, (string)e.UserState); } private void UpdateGUI(int percent, string txt) { Test_ProgressBar.Value = percent; Test_RichTextBox.AppendText(txt + Environment.NewLine); } Looking at reflector, the Control.Invoke() appears to use: this.FindMarshalingControl().MarshaledInvoke(this, method, args, 1); whereas BackgroundWorker.Invoke() appears to use: this.asyncOperation.Post(this.progressReporter, args); (I'm just guessing these are the relevant function calls.) If I understand correctly, BGW Posts to the WinForms window its progress report request, whereas Control.Invoke uses a CLR mechanism to invoke on the right thread. Am I close? And if so, what are the repercussions of using either ? Thanks

  • Drupal administration theme doesn't apply to Blocks pages (admin/build/block)

    - by hfidgen
    A site I'm creating for a customer in D6 has various images overlaying parts of the main content area. It looks very pretty and they have to be there for the general effect. The problem is, if you use this theme in the administration pages, the images get in the way of everything. My solution was to create a custom admin theme, based on the default one, which has these image areas disabled in the output template files - page.tpl.php The problem is that when you try and edit the blocks page, it uses the default theme and half the blocks admin settings are unclickable behind the images. I KNOW this is by design in Drupal, but it's annoying the hell out of me and is edging towards "bug" rather than "feature" in my mind. It also appears that there is no way of getting around it. You can edit /modules/blocks/block.admin.inc to force Drupal to show the blocks page in the chosen admin theme. BUT whichever changes you then make will not be transferred to the default theme, as Drupal treats each theme separately and each theme can have different block layouts. :x function block_admin_display($theme = NULL) { global $custom_theme; // If non-default theme configuration has been selected, set the custom theme. // $custom_theme = isset($theme) ? $theme : variable_get('theme_default', 'garland'); // Display admin theme $custom_theme = variable_get('admin_theme', '0'); // Fetch and sort blocks $blocks = _block_rehash(); usort($blocks, '_block_compare'); return drupal_get_form('block_admin_display_form', $blocks, $theme); } Can anyone help? the only thing I can think of is to push the $content area well below the areas where the image appear and use blocks only for content display. Thanks!

  • How does DateTime.Now affect query plan caching in SQL Server?

    - by Bill Paetzke
    Question: Does passing DateTime.Now as a parameter to a proc prevent SQL Server from caching the query plan? If so, then is the web app missing out on huge performance gains? Possible Solution: I thought DateTime.Today.AddDays(1) would be a possible solution. It would pass the same end-date to the sql proc (per day). And the user would still get the latest data. Please speak to this as well. Given Example: Let's say we have a stored procedure. It reports data back to a user on a webpage. The user can set a date range. If the user sets today's date as the "end date," which includes today's data, the web app passes DateTime.Now to the sql proc. Let's say that one user runs a report--5/1/2010 to now--over and over several times. On the webpage, the user sees 5/1/2010 to 5/4/2010. But the web app passes DateTime.Now to the sql proc as the end date. So, the end date in the proc will always be different, although the user is querying a similar date range. Assume the number of records in the table and number of users are large. So any performance gains matter. Hence the importance of the question. Example proc and execution (if that helps to understand): CREATE PROCEDURE GetFooData @StartDate datetime @EndDate datetime AS SELECT * FROM Foo WHERE LogDate >= @StartDate AND LogDate < @EndDate Here's a sample execution using DateTime.Now: EXEC GetFooData '2010-05-01', '2010-05-04 15:41:27' -- passed in DateTime.Now Here's a sample execution using DateTime.Today.AddDays(1) EXEC GetFooData '2010-05-01', '2010-05-05' -- passed in DateTime.Today.AddDays(1) The same data is returned for both procs, since the current time is: 2010-05-04 15:41:27.

    i am developing a ruby on rails (2.3.8) application with data storage amazon simpledb. i am using the aws-sdb gem in the version aws-sdb (0.3.1) there are a few bugs, but the problems are outlined in the comments of this tutorial from amazon: http://developer.amazonwebservices.com/connect/entry.jspa?externalID=1242 i am wondering if it is a bug of the gem or maybe a proxy issue, but i cannot delete any data from simpledb. anyone else experienced this or has a clue? >> t=Team.find(:first) => #<Team:0x329f718 @prefix_options={}, @attributes={"updated_at"=>Fri May 28 16:33:17 UTC 2010, "id"=>0}> >> t.destroy => #<Net::HTTPOK 200 OK readbody=true> >> t=Team.find(:first) => #<Team:0x321ad38 @prefix_options={}, @attributes={"updated_at"=>Fri May 28 16:33:17 UTC 2010, "id"=>0}> the team model is a normal ActiveResource Model, according to said tutorial. class Team < ActiveResource::Base self.site = "http://localhost:8888" # Proxy host + port self.prefix = "/fb2010_dev/" # SDB domain end

  • Achieving Thread-Safety

    - by Smasher
    Question How can I make sure my application is thread-safe? Are their any common practices, testing methods, things to avoid, things to look for? Background I'm currently developing a server application that performs a number of background tasks in different threads and communicates with clients using Indy (using another bunch of automatically generated threads for the communication). Since the application should be highly availabe, a program crash is a very bad thing and I want to make sure that the application is thread-safe. No matter what, from time to time I discover a piece of code that throws an exception that never occured before and in most cases I realize that it is some kind of synchronization bug, where I forgot to synchronize my objects properly. Hence my question concerning best practices, testing of thread-safety and things like that. mghie: Thanks for the answer! I should perhaps be a little bit more precise. Just to be clear, I know about the principles of multithreading, I use synchronization (monitors) throughout my program and I know how to differentiate threading problems from other implementation problems. But nevertheless, I keep forgetting to add proper synchronization from time to time. Just to give an example, I used the RTL sort function in my code. Looked something like FKeyList.Sort (CompareKeysFunc); Turns out, that I had to synchronize FKeyList while sorting. It just don't came to my mind when initially writing that simple line of code. It's these thins I wanna talk about. What are the places where one easily forgets to add synchronization code? How do YOU make sure that you added sync code in all important places?

  • Selenium RC: Selecting elements using the CSS :contains pseudo-class

    - by Andrew
    I would like to assert that a table row contains the data that I expect in two different tables. Using the following HTML as an example: <table> <tr> <th>Table 1</th> </tr> <tr> <td>Row 1 Col 1</td> <td>Row 1 Col 2</td> </tr> </table> <table> <tr> <th>Table 2</th> </tr> <tr> <td>Row 1 Col 1</td> <td>different data</td> </tr> </table> The following assertion passes: $this->assertElementPresent('css=table:contains(Table 1)'); However, this one doesn't: $this->assertElementPresent('css=table:contains(Table 1) tr:contains(Row 1 Col 1)'); And ultimately, I need to be able to test that both columns within the table row contain the data that I expect: $this->assertElementPresent('css=table:contains(Table 1) tr:contains(Row 1 Col 1):contains(Row 1 Col 2)'); $this->assertElementPresent('css=table:contains(Table 2) tr:contains(Row 1 Col 1):contains(different data)'); What am I doing wrong? How can I achieve this? Update: Sounds like the problem is a bug in Selenium when trying to select descendants. The only way I was able to get this to work was to add an extra identifier on the table so I could tell which one I was working with: /* HTML */ <table id="table-1"> /* PHP */ $this->assertElementPresent("css=#table-1 tr:contains(Row 1 Col 1):contains(Row 1 Col 2)");

  • How can I prevent the "... has stopped working" window on my Server 2008 R2 dev box?

    - by serialhobbyist
    I'm using a Windows Server 2008 x64 R2 machine as a development box. Amongst many other things I've got Visual Studio 2008 SP1 installed on it. When I'm working on a project, I sometimes need to use Debug Start without Debugging (Ctrl + F5). If the program throws an exception, I get a new R2-style window appear. I'm pretty sure I didn't see this on my XP box - this is the first time I've developed directly on a server. Is there any way to avoid this - it's really beginning to bug me? E.g. my current project is accessing a WCF service - I'm using Ctrl+F5 to start a console program client. I run it and get the window. The title is the name of the project I've just started and it contains: [insert-project-name-here] has stopped working Windows can check online for a solution to the problem. --> Check online for a solution and close the program --> Close the program --> Debug the program V View problem details. Clicking on "Close the program" will actually close the window and the exception message appears in the console, which is what I want (but without the extra window-faffing). How can I avoid this annoyance?

  • "variable tracking" is eating my compile time!

    - by wowus
    I have an auto-generated file which looks something like this... static void do_SomeFunc1(void* parameter) { // Do stuff. } // Continues on for another 4000 functions... void dispatch(int id, void* parameter) { switch(id) { case ::SomeClass1::id: return do_SomeFunc1(parameter); case ::SomeClass2::id: return do_SomeFunc2(parameter); // This continues for the next 4000 cases... } } When I build it like this, the build time is enormous. If I inline all the functions automagically into their respective cases using my script, the build time is cut in half. GCC 4.5.0 says ~50% of the build time is being taken up by "variable tracking" when I use -ftime-report. What does this mean and how can I speed compilation while still maintaining the superior cache locality of pulling out the functions from the switch? EDIT: Interestingly enough, the build time has exploded only on debug builds, as per the following profiling information of the whole project (which isn't just the file in question, but still a good metric; the file in question takes the most time to build): Debug: 8 minutes 50 seconds Release: 4 minutes, 25 seconds

  • slideDown() Makes Everything in Wrapper Shift

    - by Ben
    Hello everyone, I am currently creating a simple menu where there are several names of services and a user can click on one and jQuery will show it's corresponding paragraph describing it below it. My jQuery code is fine and does exactly what I want, however, I have one bug I have yet to iron out. Whenever I click one of these headings and it's description displays, everything in the wrapper for the page shifts to the left about 7 pixels in Firefox, it does the same thing is Google Chrome however I have not measured the amout but I am sure it is irrelevant. Anyways, I am using the slideToggle() command to show the hidden parragraph. I assume this is occuring because when the slideDown occurs it is somehow changing the width of everything and the "margin: 0 auto;" setting for the wrapper rule in my css is compensating for this change. Does anyone have any way I can remedy this problem? I have tried several other fixes I've found around the internet but to no avail. Here is what my code looks like, I put it on jsFiddle to make it easier to view: http://jsfiddle.net/vcH7m/ Feel free to edit it there if you like, or post what needs to be fixed here. Whatever is more convenient. Thank you very much for the help!

  • Connections hanging on read()

    - by viraptor
    Hi, Short version: I've got a strange issue with a server accepting TCP connections. Even though there are normally some processes waiting, at some volume of connections it hangs. Long version: The server is written in Perl and binds a $srv socket with the reuse flag and listen == 5. Afterwards, it forks into 10 processes with a loop of $clt=$srv->accept(); do_processing($clt); $clt->shutdown(2); The client written in C is also very simple - it sends some lines, then receives all lines available and does a shutdown(sockfd, 2); There's nothing async going on and at the end both send and receive queues are empty (as reported by netstat). Connections last only ~20ms. All clients behave the same way, are the same implementation, etc. Now let's say I'm accepting X connections from client 1 and another X from client 2. Processes still report that they're idle all the time. If I add another X connections from client 3, suddenly the server processes start hanging just after accepting. The first blocking thing they do after accept(); is while (<$clt>) ... - but they don't get any data (on the first try already). Suddenly all 10 processes are in this state and do not stop waiting. On strace, the server processes seem to hang on read(), which makes sense. There are loads of connections in TIME_WAIT state belonging to that server (~100 when the problem starts to manifest), but this might be a red herring. What could be happening here?

  • Export GridView to Excel (not working)

    - by Chiramisu
    I've spent the last two days trying to get some bloody data to export to Excel. After much research I determined that the best and most common way is using HttpResponse headers as shown in my code below. After stepping through countless times in debug mode, I have confirmed that the data is in fact there and both filtered and sorted the way I want it. However, it does not download as an Excel file, or do anything at all for that matter. I suspect this may have something to do with my UpdatePanel or perhaps the ImageButton not posting back properly, but I'm not sure. What am I doing wrong? Please help me to debug this issue. I will be eternally grateful. Thank you. :) Markup <asp:UpdatePanel ID="statusUpdatePanel" runat="server" UpdateMode="Conditional"> <Triggers> <asp:AsyncPostBackTrigger ControlID="btnExportXLS" EventName="Click" /> </Triggers> <ContentTemplate> <asp:GridView ID="GridView1" runat="server" AllowPaging="True" PageSize="10" AllowSorting="True" DataSourceID="GridView1SDS" DataKeyNames="ID"> </asp:GridView> <span><asp:ImageButton ID="btnExportXLS" runat="server" /></span> </ContentTemplate> </asp:UpdatePanel> Codebehind Protected Sub ExportToExcel() Handles btnExportXLS.Click Dim dt As New DataTable() Dim da As New SqlDataAdapter(SelectCommand, ConnectionString) da.Fill(dt) Dim gv As New GridView() gv.DataSource = dt gv.DataBind() Dim frm As HtmlForm = New HtmlForm() frm.Controls.Add(gv) Dim sw As New IO.StringWriter() Dim hw As New System.Web.UI.HtmlTextWriter(sw) Response.ContentType = "application/vnd.ms-excel" Response.AddHeader("content-disposition", "attachment;filename=Report.xls") Response.Charset = String.Empty gv.RenderControl(hw) Response.Write(sw.ToString()) Response.End() End Sub
