• Opening pop up in Joomla

  - by user258100

  I am trying to have people be able to open HTML widgets by clicking on a button in my Joomla page. All the widgets are different sizes. The code is entered as HTML in Jumi. Currently I have the action set to: "On click open in new window without browser navigation." The problem is this this always opens in a full screen size with the widget showing up in a corner. How do I control the size of this new window for each widget? Thanks

• How do i assert my exception message with JUNIT Test annotation ?

  - by Cshah

  i have written a few junits with @Test annotation. If my test method throws a checked exception and if i want to assert the message along with the exception, is there a way to do so with JUNIT @Test annotation.AFAIK, Junit 4.7 doesnt provide this feature but does any future versions provide it. I know in .NET you can assert the message and the exception class. Looking for similar feature in the java world. This is what i want @Test (expected = RuntimeException.class, message = "Employee ID is null") public void shouldThrowRuntimeExceptionWhenEmployeeIDisNull() { }

• Django : presenting a form very different from the model and with multiple field values in a Django-

  - by sebpiq

  Hi ! I'm currently doing a firewall management application for Django, here's the (simplified) model : class Port(models.Model): number = models.PositiveIntegerField(primary_key=True) application = models.CharField(max_length=16, blank=True) class Rule(models.Model): port = models.ForeignKey(Port) ip_source = models.IPAddressField() ip_mask = models.IntegerField(validators=[MaxValueValidator(32)]) machine = models.ForeignKey("vmm.machine") What I would like to do, however, is to display to the user a form for entering rules, but with a very different organization than the model : Port 80 O Not open O Everywhere O Specific addresses : --------- delete field --------- delete field + add address field Port 443 ... etc Where Not open means that there is no rule for the given port, Everywhere means that there is only ONE rule (0.0.0.0/0) for the given port, and with specific addresses, you can add as many addresses as you want (I did this with JQuery), which will make as many rules. Now I did a version completely "handmade", meaning that I create the forms entirely in my templates, set input names with a prefix, and parse all the POSTed stuff in my view (which is quite painful, and means that there's no point in using a web framework). I also have a class which aggregates the rules together to easily pre-fill the forms with the informations "not open, everywhere, ...". I'm passing a list of those to the template, therefore it acts as an interface between my model and my "handmade" form : class MachinePort(object): def __init__(self, machine, port): self.machine = machine self.port = port @property def fully_open(self): for rule in self.port.rule_set.filter(machine=self.machine): if ipaddr.IPv4Network("%s/%s" % (rule.ip_source, rule.ip_mask)) == ipaddr.IPv4Network("0.0.0.0/0"): return True else : return False @property def partly_open(self): return bool(self.port.rule_set.filter(machine=self.machine)) and not self.fully_open @property def not_open(self): return not self.partly_open and not self.fully_open But all this is rather ugly ! Do anyone of you know if there is a classy way to do this ? In particular with the form... I don't know how to have a form that can have an undefined number of fields, neither how to transform these fields into Rule objects (because all the rule fields would have to be gathered from the form), neither how to save multiple objects... Well I could try to hack into the Form class, but seems like too much work for such a special case. Is there any nice feature I'm missing ?

• Inline & not-inline

  - by anon

  Suppose I have: struct Vec3 { double x; double y; double z; } ; inline double dot(const Vec3& lhs, const Vec3& rhs) { return lhs.x * rhs.x + lhs.y * rhs.y + lhs.z * rhs.z ; } Is it possible to have "dot" also exist in a non-inlined version, so that it can be in the *.so , so that when I dl open it I can call it? I.e. I want files that include the above header to use the inlined version, but I also want the function to exist in a *.so, so I can dl open it and call it dynamically.

• Opening popup links in UIWebView, possible?

  - by Jasarien

  Hey guys, I have a UIWebView which I'm using as an embedded browser within my app. I've noticed that links in webpages that open new windows are ignored without any call into my code. I've tried breakpointing on - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType and then selecting a link that would open a popup window, and the breakpoint is never hit. Is there anything I can do to intercept that selection of the popup link and get the URL and just load it normally? I'm not interested in displaying a popup window in the app itself, I just want the URL of whatever is going to be loaded in the popup window to load in the main webview itself. Is this possible? Thanks!

• Number of lines in csv.DictReader

  - by Alan Harris-Reid

  Hi there, I have a csv DictReader object (using Python 3.1), but I would like to know the number of lines/rows contained in the reader before I iterate through it. Something like as follows... myreader = csv.DictReader(open('myFile.csv', newline='')) totalrows = ? rowcount = 0 for row in myreader: rowcount +=1 print("Row %d/%d" % (rowcount,totalrows)) I know I could get the total by iterating through the reader, but then I couldn't run the 'for' loop. I could iterate through a copy of the reader, but I cannot find how to copy an iterator. I could also use totalrows = len(open('myFile.csv').readlines()) but that seems an unnecessary re-opening of the file. I would rather get the count from the DictReader if possible. Any help would be appreciated. Alan

• How to play sound in Python WITHOUT interrupting music/other sounds from playing

  - by Morlock

  I'm working on a timer in python which sounds a chime when the waiting time is over. I use the following code: from wave import open as wave_open from ossaudiodev import open as oss_open def _play_chime(): """ Play a sound file once. """ sound_file = wave_open('chime.wav','rb') (nc,sw,fr,nf,comptype, compname) = sound_file.getparams( ) dsp = oss_open('/dev/dsp','w') try: from ossaudiodev import AFMT_S16_NE except ImportError: if byteorder == "little": AFMT_S16_NE = ossaudiodev.AFMT_S16_LE else: AFMT_S16_NE = ossaudiodev.AFMT_S16_BE dsp.setparameters(AFMT_S16_NE, nc, fr) data = sound_file.readframes(nf) sound_file.close() dsp.write(data) dsp.close() It works pretty good, unless any other device is already outputing sound. How could I do basically the same (under linux) without having the prerequisite that no sound is being played? If you think the process would require an API to ensure software mixing, please suggest a method :) Thx for the support

• RuntimeException: Could not start Selenium session: Internal Server Error

  - by user79685

  I am trying to detect a midair collision problem (simultaneous editin) using selenium. So I start a selenium session A with following (Super Class) selenium = new MASSelenium(serverHost, serverPort, *iexplore, browserURL); selenium.start(); selenium.open("index.cgi"); then I try starting a different selenium session B pointing to a different browser from the superclass (Sub Class): selenium2 = new MASSelenium(getServerHost(), getServerPort(), *firefox, getBrowserURL()); selenium2.start(); selenium2.open("index.cgi"); It works fine on my local machine (behaves as expected) but then when i run this same test on a remote machine (using bamboo build tool), i get this exception: java.lang.RuntimeException: Could not start Selenium session: Internal Server Error at com.thoughtworks.selenium.DefaultSelenium.start(DefaultSelenium.java:89) at gov.baba.arc.mas.selenium.tests.SimultaneousEditingConflictDetected.setUp(SimultaneousEditingConflictDetected.java:78) Caused by: com.thoughtworks.selenium.SeleniumException: Internal Server Error at com.thoughtworks.selenium.HttpCommandProcessor.throwAssertionFailureExceptionOrError(HttpCommandProcessor.java:97) at com.thoughtworks.selenium.HttpCommandProcessor.getCommandResponseAsString(HttpCommandProcessor.java:168) at com.thoughtworks.selenium.HttpCommandProcessor.executeCommandOnServlet(HttpCommandProcessor.java:104) at com.thoughtworks.selenium.HttpCommandProcessor.doCommand(HttpCommandProcessor.java:86) Any idea why this is happening?

• fstream - correct error checking after output

  What's the correct way to check for a general error when sending data to an fstream? I have the following code, which seems a bit overkill. int Saver::output() { save_file_handle.open(file_name.c_str()); if (save_file_handle.is_open()) { save_file_handle << save_str.c_str(); if (save_file_handle.bad()) { x_message("Error - failed to save file"); return 0; } save_file_handle.close(); if (save_file_handle.bad()) { x_message("Error - failed to save file"); return 0; } return 1; } else { x_message("Error - couldn't open save file"); return 0; } }

• What do you miss from classic-asp days that is not available in asp.net ?

  - by this. __curious_geek

  Many of us have come from classic-asp background and eventually picked up asp.net for better. But I miss many features from classic-asp that are not available in asp.net. Like, I don't get complete control over the markup renderred to the client in asp.net wherein in classic-asp it was possible. What are those features you miss from your classic-asp days ? PS: This question is tribute to original classic-asp that once ruled the world.

• MVC Site - Ensuring the default entry view is always correct

  - by Klaptrap

  I have a MVC site with AD authorization. This is all working fine. I publish the site to the webserver and call the site directly (http://intranet). If I have not logged in for a while (I have an authorised cookie with a 30 minute TTL), I am prompted to log-in and if successful I am redirected to the homeController's index view. This is great and as expected. If I keep the session open (browser open) and browse away from the site, if I then browse back to http://intranet, I am not challenged as I have recently authenticated but the default page is from a different controller and not the home page view. How can I stop this from happening? It cannot be a session setting as this is not a new session and the routes appear correct - they are not beng called at this point anyhow. Please MVC guru's advise....!

• File Uploads with Turbogears 2

  - by William Chambers

  I've been trying to work out the 'best practices' way to manage file uploads with Turbogears 2 and have thus far not really found any examples. I've figured out a way to actually upload the file, but I'm not sure how reliable it us. Also, what would be a good way to get the uploaded files name? file = request.POST['file'] permanent_file = open(os.path.join(asset_dirname, file.filename.lstrip(os.sep)), 'w') shutil.copyfileobj(file.file, permanent_file) file.file.close() this_file = self.request.params["file"].filename permanent_file.close() So assuming I'm understanding correctly, would something like this avoid the core 'naming' problem? id = UUID. file = request.POST['file'] permanent_file = open(os.path.join(asset_dirname, id.lstrip(os.sep)), 'w') shutil.copyfileobj(file.file, permanent_file) file.file.close() this_file = file.filename permanent_file.close()

• Is the board game "Go" NP complete?

  - by sharkin

  There are plenty of Chess AI's around, and evidently some are good enough to beat some of the world's greatest players. I've heard that many attempts have been made to write successful AI's for the board game Go, but so far nothing has been conceived beyond average amateur level. Could it be that the task of mathematically calculating the optimal move at any given time in Go is an NP-complete problem?

• Trapping errors in TClientDataSet.CommandText

  - by Rob McDonell

  I have a TClientDataSet connected to a TDataSetProvider, which in turn is connected to a TAdsTable. I set the SQL command and then open the ClientDataset something like this: try CDS.CommandText := 'SELECT * FROM tablename WHERE fieldname = 1'; CDS.Open except // trap exception here - this never gets executed! end; If the SQL statement in CommandText fails, however (syntax error or whatever) I get an exception within the Advantage code, but it never gets caught in my own exception handling code. Is there any way for me to trap this error and report it nicely to the user. Alternatively is there a way to verify the syntax of an SQL query before executing it? I'm using Delphi Pro 2009, and Advantage Local Server 9.
