• Plone, behaviour of URLs

  - by jpet

  The situation is the following: I created a site with Plone, developed, used, but behind a test URL. Now it has to be published, but the test URL is not appropriate and I don't want to move the site. I think, if I use a redirect, it won't be appear in the URL-bar, only in the case of site start page. Am I wrong? (The test URL should not be used, because it will be a "semi-official" site.) What do you suggest to do? As far as I can see Plone uses absolute URLs everywhere. I can add relative URLs, but if I create a new page, a new event, etc., then they have absolute URLs on other automatically generated inner pages. Is there any way to convert these URLs to relative paths? Is there any setting possibilty where only a checkbox changes this default setting?

• Query multiple models with one value

  - by swoei

  I have multiple models which all have a FK to the same model. All I know is the FK how can I determine which of the models has the FK attached? Below an example to clearify: class ModelA(models.Model): title = models.CharField("title", max_length=80) class ModelB(models.Model): fk = models.ForeignKey(ModelA) class ModelC(models.Model): fk = models.ForeignKey(ModelA) How can I figure out without using a try/except on each model whether B or C has the FK? (The FK can only be in one of them, for the record in this case I only added two models but in the real world app there are multiple possible x amount of models which have the FK to modelA)

• PHP Linefeeds (\n) Not Working

  - by dosboy

  For some reason I can't use \n to create a linefeed when outputting to a file with PHP. It just writes "\n" to the file. I've tried using "\\n" as well, where it just writes "\n" (as expected). But I can't for the life of me figure out why adding \n to my strings isn't creating new lines. I've also tried \r\n but it just appends "\r\n" to the line in the file. Example: error_log('test\n', 3, 'error.log'); error_log('test2\n', 3, 'error.log'); Outputs: test\ntest2\n Using MAMP on OSX in case that matters (some sort of PHP config thing maybe?). Any suggestions?

• How do I get query string value from script path?

  - by TruMan1

  I am adding my Javsacript file in pages with different query strings in the script path like this: Page1: <script type="text/javascript" src="file.js?abc=123"></script> Page2: <script type="text/javascript" src="file.js?abc=456"></script> Page3: <script type="text/javascript" src="file.js?abc=789"></script> In my Javascript file, how can I get the value of the "abc" param? I tried using window.location for this, but that does not work. In case it helps, below is a function I use to find the value of a query string param: function getQuerystring(key, defaultValue) { if (defaultValue == null) defaultValue = ""; key = key.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]"); var regex = new RegExp("[\\?&]" + key + "=([^&#]*)"); var qs = regex.exec(window.location.href); if (qs == null) return defaultValue; else return qs[1]; }

• Winform not scrolling when drawing objects on it

  - by dezkev

  Hello All, C#3.0,.net framework 3.5 I am drawing ( using the draw method in the graphics class) a lot of solid rectangles on a windows form vertically. The form starts at 500 x 500 px and the rectangles are only drawn at runtime after data is downloaded from the net -and the number of rectangles depends on the download so I do not know it upfront. So only a few rectangles are drawn as the size of the form is fixed. So I googled/Binged ( lest someone suggest I do that) and found a few tips but they don't work in this case -like setting the forms AutoScroll property to true or trying double buffering.I also tried to draw on a listbox control and set it's scroll property etc...but no dice. I'm guessing there is no way to display , say 200 rectangles vertically on a windows form using draw. I need some other solution... any ideas please. Maybe a list of pictureboxes and then populate each picturebox with the solid color ? Thanks

• MPI C fprintf() output not showing up if the process hangs on MPI_Recv

  - by Karolis

  I'm writing an MPI C program. I have troubles debugging it, because whenever I use fprintf, like this: fprintf(stdout, "worker: %d", worker); if the program hangs, because of some blocking MPI_Recv, I can't see any output. I'm sure the line of code is reached, because I can put a return statement after the fprintf statement, in which case the process finishes execution and the output is printed. Any ideas, on how to print (see the output) even though the process gets blocked later by Recv? I hope this makes sense.

• Any solution or programming tips for Inner class?

  - by huahsin68

  Hi, I'm having some toubt here. Hope you guys can share out some programming tips. Just curious to know whether is it a good programming practice if I do something like the code below. class Outer { public: class Inner { public: Inner() {} } Outer() {} }; I have been doing this for structure where I only want my structure to be expose to my class instead of global. But the case is different here, I am using a class now? Have you guys facing such a situation before? Very much appreciated on any advice from you ;)

• .NEt on WIN to Mono on Ubuntu

  - by Srikanth

  I am looking at a possibility to change my ASP.NET 2.0 app to Mono framework. I have used the mono analyzer tool and it does detect some p/invoke and interop dependencies. For ex. 1) We use excel interops and on linux we are looking to use staroffice/Openoffice instead. Is there an easy way of substituting excel with staroffice? (I know it sounds bizarre, but just don't want to miss out in case anyone has done it already.) 2) LDAP auth: What could be the best alternative in Ubuntu (or an other flavour of Linux) ? 3) Is there an ajax framework for mono? Preferably with similar controls as Atlas?? I hope I am not too ambitious here.. thanks.

• Where are the really high quality and complex Swing components?

  - by jouhni

  Looking at Swing, I have the feeling that it comes with many useful and reasonable atomic components in its core. And when I look at the Web there are hundrets of quickly plugged together components (among them many date/time pickers, pimped lists and tables), which have in common that I could easily write them on my own, if I needed them. When I build big software and come to the point where I need a domain-specific component which is really big, I mostly come to the point where I have to write it on my own, which, due to the point that they are not just plugged together lists and tables, isn't done qickly. So, the question is, why are there no Swing component galleries which contain more than just customized date/time pickers or lists with added tree support. Where are the components which really raise the level of abstraction, or are in best case domain-specific?

• Strange error: cannot convert from 'int' to 'ios_base::openmode'

  - by Dylan Klomparens

  I am using g++ to compile some code. I wrote the following snippet: bool WriteAccess = true; string Name = "my_file.txt"; ofstream File; ios_base::open_mode Mode = std::ios_base::in | std::ios_base::binary; if(WriteAccess) Mode |= std::ios_base::out | std::ios_base::trunc; File.open(Name.data(), Mode); And I receive these errors... any idea why? Error 1: invalid conversion from ‘int’ to ‘std::_Ios_Openmode’ Error 2: initializing argument 2 of ‘std::basic_filebuf<_CharT, _Traits* std::basic_filebuf<_CharT, _Traits::open(const char*, std::_Ios_Openmode) [with _CharT = char, _Traits = std::char_traits]’ As far as I could tell from a Google search, g++ is actually breaking the C++ standard here. Which I find quite astonishing, since they generally conform very strictly to the standard. Is this the case? Or am I doing something wrong. My reference for the standard: http://www.cplusplus.com/reference/iostream/ofstream/open/

• C#, WinForms: What would prevent KeyDown events from chaining up from focused control up to main For

  - by blak3r

  As i understand it, when a keyboard button is pressed it should invoke the KeyDown event for the control which has focus. Then, the KeyDown for the parent control, so on and so forth until it reaches main form. UNLESS - along the chain one of the EventHandlers did: e.SuppressKeyPress = true; e.Handled = true; In my case, KeyDown events never get to the main form. I have Form - Panel - button for example. Panel doesn't offer a KeyDown Event, but it shouldn't stop it from reaching the main form right? Right now as a work around I set every single control to call an event handler I wrote. I'm basically trying to prevent Alt-F4 from closing the application and instead minimize it.

• Is there any self-improving compiler around?

  - by JohnIdol

  I am not aware of any self-improving compiler, but then again I am not much of a compiler-guy. Is there ANY self-improving compiler out there? Please note that I am talking about a compiler that improves itself - not a compiler that improves the code it compiles. Any pointers appreciated! Side-note: in case you're wondering why I am asking have a look at this post. Even if I agree with most of the arguments I am not too sure about the following: We have programs that can improve their code without human input now — they’re called compilers. ... hence my question.

• Delphi constants and references

  - by Sambatyon

  I want to pass constant references to functions in delphi, so I am sure that the referenced object won't change and to save time and memory. So I want to declare a function like function foo(var const Value : Bar) : Boolean; however this is not allowed. I thought constant values would be automatically sent as references. However I found out that it is not the case (getting the address of an object before sending it to the function gives me $12F50C and the address of the same object inside the function is $12F564) What can I do to send constant references?

• Can I do transactions and locks in CouchDB?

  - by damian

  I need to do transactions (begin, commit or rollback), locks (select for update). How can I do it in a document model db? Edit: The case is this: I want to run an auctions site. And I think how to direct purchase as well. In a direct purchase I have to decrement the quantity field in the item record, but only if the quantity is greater than zero. That is why I need locks and transactions. I don't know how to address that without locks and/or transactions. Can I solve this with CouchDB?

• Substring extraction using bash shell scripting and awk

  - by rohanbk

  So, I have a file called 'dummy' which contains the string: "There is 100% packet loss at node 1". I also have a small script that I want to use to grab the percentage from this file. The script is below. result=`grep 'packet loss' dummy` | awk '{ first=match($0,"[0-9]+%") last=match($0," packet loss") s=substr($0,first,last-first) print s}' echo $result I want the value of $result to basically be 100% in this case. But for some reason, it just prints out a blank string. Can anyone help me?

• Eclipse debugging "source not found"

  - by James

  I just started using Eclipse so go easy on me ;). But when trying to debug a JUnit test case I get a dialog that states the the source is not found when I get to this line in the code in my test method: Assert.assertEquals(1, contents.size()); I know I should probably go and try and download the source from somewhere, but I really don't want to because I have no interest in stepping into the JUnit code. I have the JUnit runtime jar so Why does Eclipse expect me to have all the referenced tools source code in order to debug my own code (seems somewhat silly)? My main question is though, how can I tell Eclipse to skip this dialog when the source is not available and allow me to continue to debug my own code? [Edit] I've isolated the cause of this. It seems that Eclipse seems to think it needs the source when an exception is thrown by the internal JUnit code. In general is there anyway to tell it that it doesn't and just have it throw up an error dialog of some kind instead?

• Why not speed up testing by using function dependency graph?

  - by Maltrap

  It seems logical to me that if you have a dependency graph of your source code (tree showing call stack of all functions in your code base) you should be able to save a tremendous amount of time doing functional and integration tests after each release. Essentially you will be able to tell the testers exactly what functionality to test as the rest of the features remain unchanged from a source code point of view. If for instance you change a spelling mistake in once piece of the code, there is no reason to run through your whole test script again "just in case" you introduced a critical bug. My question, why are dependency trees not used in software engineering and if you use them, how do you maintain them? What tools are available that generate these trees for C# .NET, C++ and C source code?

• How to name variables wich are structs

  - by evilpie

  Hello, i often work on private projects using the WinApi, and as you might know, it has thousands of named and typedefed structs like MEMORY_BASIC_INFORMATION. I will stick to this one in my question, what still is preferred, or better when you want to name a variable of this type. Is there some kind of style guide for this case? For example if i need that variable for the VirtualQueryEx function. Some ideas: MEMORY_BASIC_INFORMATION memoryBasicInformation; MEMORY_BASIC_INFORMATION memory_basic_information; Just use the name of the struct non captialized and with or without the underlines. MEMORY_BASIC_INFORMATION basicInformation; MEMORY_BASIC_INFORMATION information; Short form? MEMORY_BASIC_INFORMATION mbi; I often see this style, using the abbreviation of the struct name. MEMORY_BASIC_INFORMATION buffer; VirtualQueryEx defines the third parameter lpBuffer (where you pass the pointer to the struct), so using this name might be an idea, too. Cheers

• setting a timeout for an InputStreamreader variable

  - by Noona

  I have a server running that accepts connections made through client sockets, I need to read the input from this client socket, now suppose the client opened a connection to my server without sending anything through the server's socket outputstream, in this case, while my server tried to read the input through the client socket's inputstream, an exception will be thrown, but before the exception is thrown i would like a timeout say of 5 sec, how can I do this? currently here's how my code looks like on the server side: try { InputStreamReader clientInputStream = new InputStreamReader(clientSocket.getInputStream()); int c; StringBuffer requestBuffer = new StringBuffer(); while ((c = clientInputStream.read()) != -1) { requestBuffer.append((char) c); if (requestBuffer.toString().endsWith(("\r\n\r\n"))) break; } request = new Request(requestBuffer.toString(), clientSocket); } catch (Exception e) // catch any possible exception in order to keep the thread running { try { if (clientSocket != null) clientSocket.close(); } catch (IOException ex) { ex.printStackTrace(); } System.err.println(e); //e.printStackTrace(); }

• Testing if a UI element is hidden in an OCUnit test

  - by Logan Serman

  I have a button that is hidden under certain circumstances that I wish to test. The button is hidden with [theButton setHidden: YES] in the viewDidLoad method if it is appropriate. For simplicity, lets say that the button is hidden when the buttonIsHidden property is set to true in the view controller. Right now I am trying the following: self.viewController = [[ViewController alloc] init]; self.viewController.buttonIsHidden = YES; [self.viewController loadView]; UIButton *theButton = [...] // function I wrote to retrieve the button based on it's touch up inside action if (theButton) { NSLog(@"%c", theButton.hidden); return (theButton.hidden == true) } return NO; It looks like the hidden property is not what it should be, the NSLog lines from the above code are blank. But, if I output another property like the height, it outputs the correct value so I know it is getting the right button. How do I access the hidden property of the button in this case?

• [WM6] Owner of a component. What exactly is this for?

  - by kornelijepetak

  I am developing an app for Windows Mobile 6 and there is a CameraCaptureDialog class that enables me to call a camera app from my own application. The class has an Owner property that most examples on the internet set to "this". cam.Owner = this; What exactly does this do? I've seen a similar scenario with Windows Forms components/controls by setting the Parent control. In that case I guess it's used only for layout algorithms, but other than that, is there any useful purpose? I don't see how setting an owner of the CameraCaptureDialog can (and actually does not) make any difference (at least not a visible one). Any insight would be appreciated.

• DataGridView and checkboxes re-selecting automatically

  - by SuperFurryToad

  I have a strange problem with a DataGridView I'm using which is bound to a table in VB.net I've added a checkbox column to allow a user to tick a bunch of rows that I can then loop through and save off to a different table. All the checkboxes are enabled by default. So it's really a case of unchecking the rows which aren't required. However, the DataGridView re-enables any checkbox that I click after I click on a checkbox in another row. So in effect, only one row can be unchecked at a time. I'm sure I'm probably missing something obvious here?

• Rails - how do you create a user index page like stack overflows with multiple tabs whilst keeping t

  On stackoverflow in the users profile area there are many tabs which all display differing information such as questions asked and graphs. Its the same view though and im wondering hows its best to achieve this in rails whilst keeping the controller skinny and logic in the view to a minimum. def index @user = current_user case params[:tab_selected] when "questions" @data = @user.questions when "answers" @sentences = @user.answers else @sentences = @user.questions end respond_to do |format| format.html # index.html.erb nd end but how do i process this in the index view without a load of if and else statments. And if questions and answers are presented differently whats the best way to go about this.

• Web services Authentication Jungle

  - by redben

  I have been doing some research lately about best approaches to authenticating web services calls (REST SOAP or whatever). But none of the Approaches convinced me... But i still can't a make a choise... Some talk about SSL and http basic authentication -login/password- which just seems weird for a machine (i mean having to assign a login/password to a machine, or is it not ?). Some others say API keys (seems like these scheme is more used for tracking and not realy for securing). Some say tokens (like session IDs) but shouldn't we stay stateless (especially if in REST style) ? In my use case, when a remote app is calling one of our web services, i have to authenticate the calling application obviously, and the call must - if applicable - tell me which user it impersonates so i can deal with authorization later. Any thoughts ?
