• SVN Export in Eclipse removes labels on tabs

  - by Sorcy

  I have a very strange effect when using subclipse with eclipse. Whenever I use Team-Export to export a file from the editor the export works fine, but the label of the tab of the file is removed. Effect can be seen here: http://www.daspferd.de/img/tabs.png Strangely enough it happens with php-files, css-files, html-files but NOT with javascript-files. So I'm assuming it's some kind of setting that I haven't found yet and not a bug in subclipse. Anyone know where I can shut down this behaviour?

• Rendering inconsistencies in Internet Explorer

  - by gmunk

  Hello, I have some weird problem in rendering some xhtml in IE 8 http://img709.imageshack.us/i/scrj.png/. Here is the screenshot. As shown the greet me submit button is higher than the text field. Which is kind of odd. I checked with some other browsers and it works fine, it also works fine on Windows 7 with IE 8. Here is the code for the site: http://pastebin.com/cUkVA1HP http://pastebin.com/nU4cdpDE and the reset I'm using http://pastebin.com/uyEbAsEF I'm really puzzled by this strange behaviour. Thanks in advance for any ideas.

• Django Inherited Field Access

  - by Rick

  As of the most current version, Django does not allow a subclass to have a variable with the same name as a variable in its superclass, if that variable is a Field instance. I need a subclass to modify this variable, which I call 'department'. Calling my classes super and sub, I need sub to modify the department variable it inherits from super. If I redeclare it, Django throws a field error. Of course, if I don't, department is not in scope for reassignment. If super has no department I get database errors. I get weird behaviour when I try rewriting init: def __init__(self): super(theSuperClass, self).__init__() TypeError: super(type, obj): obj must be an instance or subtype of type Anyone have any idea how to do this?

• StreamWriter does throw exception underlying connection is broken?

  - by Jane

  I am using StreamWriter instantiated over a Tcpstream like this streamWriter = new StreamWriter(tcpClient.GetStream()); I am confused about the behaviour of following calls with regards to Exceptions. The following two functions are expected to raise IOException , Surprisingly they do not raise the IOException when the server is to which the tcpClient is connected is disconnected and therefore the underlying TCP client connection is broken.. These two lines execute without raising any Exception. Why ? streamWriter.WriteLine(strBuffer); streamWriter.Flush();

• jQuery text attribute selector

  - by Shagglez

  I am trying to use the text attribute as a selector, but I can't quite grasp the behaviour, would really appreciate if someone could explain. For example given <span class="span_class"><a class="a_class">text</a></span>, $('a.a_class').text() gives "text" as expected. However $('a.a_class[text]') wouldn't match any elements, and neither would $('span.span_class > a.a_class[text]'), but $('span.span_class* > a.a_class[text]') would (although not in IE). The only workaround I can think of for IE, is loop through all anchors contained in a span, use .text() on each and match it against a certain criteria, but it seems slower than using in-built selectors. Anyone have better ideas?

• jQuery UI - Accordion Display issues

  - by Dave Kiss

  My accordion is working properly, but I'm having a few CSS and JS issues that are prohibiting it from displaying correctly. http://jsfiddle.net/frEWQ/ The JS is applying .ui-corners-all to the H3 before the "kwick" div below it has finished collapsing, giving an odd cut-off border during the animation The margin-bottom applied to the "kwick" div to give spacing between each tab disappears when the tab is set to display:none, getting rid of the spacing... but I can't apply the margin-bottom to the header because it disconnects the header from the "kwick" div below it. Any suggestions? Modification to the JS/CSS? Thanks

• Log4net rollingfile appender skipping every other day in asp.net mvc app

  - by tasty_spider_men

  Hi, I've set up some log4net logging on an asp.net mvc application i've had running for a little over a month now. I've set up rolling file (and smtp) appender on it. The application is hit several thousand times a day - alot of actions are logged. On top of these a number of batch jobs are run as part of the application that also write to the log. Now - as i've been occupied with other work, i've not attended to this application much assuming things to be working based on my test setup. Unfortunately i discover that the rolling file appender on my production server seems to be skipping every other day. Ie i have logs : 10/4/2010, 10/4/2010.1, 10/4/2010.2, 12/4/2010, 12/4/2010.1 , 14/4/2010, 14/4/2010.1 etc. Any idea what could be causing this? It is absolutely impossible that there has no action on these odd days for the lifetime of the application. Cheers

• Java long task - Did it stop writing to file?

  - by rockit

  I am writing a lot of data to a file, and while keeping my eye on the file it eventually stopped growing in size. Essentially my task is getting information from a database, and printing out all non-unique values in column A. Since there are many rows to the database table, and the database table is across my network, this is taking days to complete. Thus I'm concerned that since the file isn't growing, that it isn't actually writing to the file anymore. Which is odd, I have no "catch"'s in my code, so if there was a problem writing to file, wouldn't it have thrown an error?! Should I let the task complete (estimate 2-3 days from today), or is there something else that I don't know going on here making my application not write to the file?! my algorithm goes something like this Declare file Create new file Open file for writing get database connection get resultset from database for each row in the resultset - write column "A" to file - if row# % 100000 then write to screen "completed " + row# + " rows" when no more rows exist close file write to screen - "completed"

• jQuery blockUI and AJAX POST

  - by oompahloompah

  I am using jQuery BlockUI in a project. For a particular user action, I want to block the UI, and then POST data to the server. When the timeout event occurs OR the server returns, I want to unblock the page. I can't seem to implement this behaviour. This is what I have so far (not working) $(document).ready(function(){ $('#test').click(function(event){ $.blockUI({ message: $('#syntax-chk') }); $.ajax({ type: 'POST', url: 'www.example.com', data: somedata, dataType: "json" }); setTimeout(function() { $.unblockUI({ onUnblock: function(){ alert('onUnblock'); } }); }, 2000); }); can anyone spot what I may be doing wrong?

• printing double in binary

  - by Happy Mittal

  In Thinking in C++ by Bruce eckel, there is a program given to print a double value in binary.(Chapter 3, page no. 189) int main(int argc, char* argv[]) { if(argc != 2) { cout << "Must provide a number" << endl; exit(1); } double d = atof(argv[1]); unsigned char* cp = reinterpret_cast<unsigned char*>(&d); for(int i = sizeof(double); i > 0 ; i -= 2) { printBinary(cp[i-1]); printBinary(cp[i]); } } Here while printing cp[i] when i=8(assuming double is of 8 bytes), wouldn't it be undefined behaviour? I mean this code doesn't work as it doesn't print cp[0].

• are runtime linking library globals shared among plugins loaded with dlopen?

  - by conejoroy

  I've a C++ program that links at runtime with, lets say, mylib.so. then, the same program uses dlopen()/dlsym() to load a function from myplugin.so, dynamic library that in turn has dependencies to mylib.so. My question is: will the program AND the function in the plugin access the same globals defined in mydlib.so in the same memory area reserved for the program, or each will be assigned different, unrelated copies in its own memory space? if the latter is the default behaviour, is it possible to change that? Thanks in advance =)!

• Problem with non data bound value in ASP.NET DropDownList.

  - by ProfK

  I'm trying to 'inject' an [All Regions] item into my regions dropdown, as follows: <asp:DropDownList ID="regionList" runat="server" AutoPostBack="true" AppendDataBoundItems="true" Width="200px" DataSourceID="regionDataSource" DataTextField="Desc" DataValueField="RegionId"> <asp:ListItem Selected="True" Value="">[All Regions]</asp:ListItem> </asp:DropDownList> I also have a rank dropdown, for taxi ranks in a region, with the following select parameter: <asp:ControlParameter ControlID="regionList" Name="RegionId" PropertyName="SelectedValue" Type="Int32" DefaultValue="" ConvertEmptyStringToNull="true" /> So the expected behaviour is that when [All Regions] is selected, the ranks dropdown should get a null parameter, and mt SQL selects all ranks, for all regions. I know my SQL works with a null parameter, but the ranks dropdown is not data binding when I select [All Regions] on the region list. It binds when I select a region from the DB, but keeps that binding when I select [All Regions] again. What am I doing wrong?

• Wpf button click when application window is not active

  - by byte

  I have a WPF application window with a button (ButtonA) which has a command binding to a View Model property. When another application is launched the focus is lost and application window is deactivated. Clicking ButtonA now doesn’t execute the command but instead only activates the window and sets the focus to the button. 2nd click is required to fire the command. The desired functionality is on click of ButtonA while the application window is not active, the application window activates and command associated with ButtonA is executed. I have also tried removing the command and adding a click handler for test purpose but this displays same behaviour. I appreciate any help with this issue.

• Make DLL dependent to other DLLs (Visual Studio IDE)

  - by Artefacto

  I'm having an inconsistency when compiling a DLL (let's call it x.dll) by calling cl.exe obj1.obj obj2.obj ... lib1.lib lib2.lib ... /link /out:x.dll /dll /debug and When using the IDE (which calls link directly, I believe). Let's say lib1.lib is an import library for lib1.dll. Opening the DLL generated by calling cl.exe in the depency walker shows it depends on lib1.dll. However, when using the IDE, the generated program is smaller and does not depend on lib1.dll. This IDE-generated image makes the program that uses x.dll crash sometimes. The question is: how do I get the correct behaviour from the IDE?

• javascript popup reloads parent page -

• Visual Studio 2005 - strange characters rendered for ANSI text

  - by Apogee

  Hi all, Has anyone seen this odd text rendering issue in VS2005 before? The first line of using statements actually says "using System;". If I copy the line as it is displayed and paste into notepad, the text appears correctly, so clearly the character codes are correct. In addition, the solution compiles and runs correctly. I was thinking it might be due to ClearCase using a different character encoding as all the solutions we're using were freshly checked-out yesterday on to a new build machine, but this is only happening in 2 of our ~30 solutions. Incidentally the same .cs files when opened in VS2008 render correctly on this machine, could this be a corruption in VS2005?

• gwt - Using List<Serializable> in a RPC call?

  - by Garagos

  I have a RPC service with the following method: public List<Serializable> myMethod(TransactionCall call) {...} But I get a warning when this method is analyzed, and then the rpc call fails Analyzing 'my.project.package.myService' for serializable types Analyzing methods: public abstract java.util.List<java.io.Serializable> myMethod(my.project.package.TransactionCall call) Return type: java.util.List<java.io.Serializable> [...] java.io.Serializable Verifying instantiability (!) Checking all subtypes of Object wich qualify for serialization It seems I can't use Serializable for my List... I could use my own interface instead (something like AsyncDataInterface, wich implements the Serializable interface) but the fact is that my method will return a list custom objects AND basic objects (such as Strings, int....). So my questions are: Is it a standart behaviour? (I can't figure out why I can't use this interface in that case) Does anyone have a workaround for that kind of situation?

• SQLITE (C/C++interface) - How to commit a transaction

  - by AJ

  I am using sqlite c/c++ interface. Now here is my scenario - I have 3 tables (related tables) say A, B, C. Now, there is a function called Set, which get some inputs and based on the inputs inserts rows into these three tables. (sometimes it can be an update in one of the tables) Now I need two things. One, i dont want autocommit feature. Basically I would like to commit after every 1000 calls to Set function Secondly, within the set function itself, if i find that after inserting into two tables, the third insert fails, then i have to revert, those particular changes in that Set function call. Now i dont see any sqlite3_commit function exposed. I only see a function called sqlite3_commit_hook() which is slightly diff in documentation. Are there any function exposed for this purpose? or What is the way to achieve this behaviour? Can you help me with the best approach of doing this. Regards, Arjun

• "Socket operation on non-socket" error due to strange sytax

  - by Robert S. Barnes

  I ran across the error Socket operation on non-socket in some of my networking code when calling connect and spent a lot of time trying to figure out what was causing it. I finally figured out that the following line of code was causing the problem: if ((sockfd = socket( ai->ai_family, ai->ai_socktype, ai->ai_protocol) < 0)) { See the problem? Here's what the line should look like: if ((sockfd = socket( ai->ai_family, ai->ai_socktype, ai->ai_protocol)) < 0) { What I don't understand is why the first, incorrect line doesn't produce a warning. To put it another way, shouldn't the general form: if ( foo = bar() < baz ) do_somthing(); look odd to the compiler, especially running with g++ -Wall -Wextra? If not, shouldn't it at least show up as "bad style" to cppcheck, which I'm also running as part of my compile?

• Know if a Visual Studio Website project is recompiling itself in the background?

  - by jdk

  A number of team members update a central ASP.NET dev site (Website project, not a Web application type). Some kinds of changes cause a recompile/rebuild in it. The large website takes a while to recompile and we've noticed it will still seemingly serve out dynamic pages before everything is internally updated. During the site's "gestation" period, our mileage varies while hitting it. Sometimes we get a correct page, sometimes an compilation error page that will eventually be served up without a compilation error, and at other times an unexpected hybrid. Is it possible to query an ASP.NET website application to see if it's currently compiling or rebuilding itself? If so I would write a status page that the team could reference when they're getting weird behaviour, so they would know to wait. Update: Our team often edit files manually on the dev server. For production we'd make pre-compiled pushes. The dev environment is a little more malleable and ever-changing so I'm looking for a solution to reducing the "confusion" there.

• Jquery Hover Flickering issue

  - by Muhammad Faisal

  Hi, Hope u people will be fine. Here is my basic code: http://jsfiddle.net/kr9pY/7/ in this demo you can see when we hover on div with id="container", a div with class="nav" fades in. But the problem is that after doing this if i hover on div with class="nav" the div fades out and in again, and if i mover cursor slightly within .nav div, it repeats this behavior repeatedly. I don't want to this behaviour when we hover on .nav div or mover cursor within this div. Thank, and sorry for my bad english.

• Streaming data to the browser as a file of unknown size

  - by Sir Psycho

  I have some data which is queried from the database and I'd like to send it to the client as a csv file. The file size varies each time due to the fact that the DB data returned can be of any size. Instead of saving this file to the hard disk, I'd like to send it to the browser at the same time it's being processed into a CSV by my algorithm. Response.Write seems useless. For some reason, the file download dialog is only displayed once my processing is finished. This seems odd as I'm writting all my output to the Response.Output stream. I have downloaded files on the web before where the filesize is not known and the browser just keeps on downloading. Is there any way to achieve this? The following stackoverflow thread did not offer any good advise. http://stackoverflow.com/questions/873995/asp-net-downloading-large-files-of-unknown-size Thanks

• Django template context not working with imported class

  - by Andy Hume

  I'm using Django's templating on appengine, and am having a problem whereby a class I'm importing from another package is not correctly being made available to the template context. Broadly speaking, this is the code. The prop1 is not available in the template in the first example below, but is in the second. MyClass is identical in both cases. This does not work: from module import MyClass context = MyClass() self.response.out.write(template.render(path, context)) This does: class MyClass(object): def __init__(self): self.prop1 = "prop1" context = MyClass() self.response.out.write(template.render(path, context)) If I log the context in the above code I get: <module.MyClass object at 0x107b1e450> when it's imported, and: <__main__.MyClass object at 0x103759390> when it's defined in the same file. Any clues as to what might cause this kind of behaviour?

• elastic / snaking line algorithm

  - by vhdirk

  Hi everyone I am making a graphics application in which I can edit a polyline by dragging the control point of it. However, I'd like to make it a bit easier to use by making it elastic; When dragging a control point, instead of moving a single point, I'd like the points within a certain distance of that point to be moved as well, depending on how hard the control point is 'pulled'. Does anyone know a simple algorithm for this? It may be quite rudimentary, as the primary requirement is speed. Actually, knowing how to call such behaviour would also be nice, so I can look it up on google. I tried 'snaking' line, but that seems to refer to active contours, which isn't what I'm looking for. Thanks
