  • Is eclipse's Garbage Collector different than the default?

    - by Savvas Dalkitsis
    From questions posted here and an old one of mine I have created the impression that you cannot explicitly run the Java Garbage Collector whenever you please. If you call it, you simply instruct the system to call it whenever it can or thinks is appropriate. But in eclipse, if you press the "Run Garbage Collector" button you see an immediate reduction in memory usage. How is that possible? Is eclipse using a different Garbage Collector, does it have access to some secret API that we don't or is my conception of how the GC works wrong?

  • How can I switch from a custom linux network namespace back to the default one?

    - by Martin
    With ip netns exec you can execute a command in a custom network namespace - but is there also a way to execute a command in the default namespace? For example, after executing these two commands: sudo ip netns add test_ns sudo ip netns exec test_ns bash How can the newly created bash execute programs in the default network namespace? There is no ip netns exec default or anything similar as far as I've found. My scenario is: I want to run a SSH server in a separate network namespace (to keep the rest of the system unaware of the network connection, as the system is used for network testing), but want to be able to execute programs in the default network namespace via the SSH connection. What I've found out so far: Created network namespaces are listed as files under /var/run/netns (but there is no file for the default namespace) The ip netns exec code can be found here: http://git.kernel.org/cgit/linux/kernel/git/shemminger/iproute2.git/tree/ip/ipnetns.c#n132 - I haven't grasped everything that it is doing yet, but it doesn't look very promising. ip netns identify $$ as suggested by Howto query and change network namespace on linux? returns nothing when in the default network namespace

  • C# define string format of double/floats to be US english by default

    - by neil
    Hi, I have got several thousands of lines of a web application source code, initially written on a US development system, to maintain. It makes heavy use of SQL statement strings, which are combined on the fly, e.g. string SQL = "select * from table where double_value = " + Math.Round(double_value, 2); Don't comment on bad programming style, that doesn't help me in this case :) The cruix: My system uses a German locale, which in turn leads to wrong SQL statements, like this: "select * from table where double_value = 15,5" (Note the comma as decimal separator instead of a point). Question: What is the most "elegant" way to change the locale of the web app in this case) to US or UK in order to prevent being forced to change and inspect every single line of code? .net 3.5 is not an option (would give me the chance to overwrite ToString() in an extension class) Kind regards

  • Setting wildcard queries as default for QueryParser

    - by user46703
    When my users enter a term like "word" I would like it be treated as a wildcard query "word*" so all terms beginning "word" are found. Is there a way to tell the QueryParser to automatically create wildcard queries or do I have to parse the query myself? This shouldn't be a problem for simple queries but it may become tricky for more complex queries.

  • Default update detailViewController, HELP.

    - by DrBeak1
    I've created an app that allows users to add information (from an addViewController), which is then displayed in a UITableView on the rootViewController. When the user taps the tableViewCell the detailViewController then displays, you guessed it, more details regarding the inputted user information. What I'm trying to accomplish is to setup an editViewController that will allow users to edit information they've already submitted. Currently, I'm trying to auto-populate the editViewController with the information that was previously submitted by the user (after which they can press save and update the info). However, I'm getting stuck trying to perform this auto-populating and I'm not sure this is even the best route to accomplish this. Here is the edit method that is called to load the editViewController from the detailViewController. -(IBAction)editDetails:(id)sender { editViewController *evc = [[editViewController alloc] initWithNibName:@"editViewController" bundle:nil]; rootViewController *rvc = [[rootViewController alloc] init]; UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:evc]; [[self navigationController] presentModalViewController:navigationController animated:YES]; ///For Style NSInteger styleCount = [[rvc scoreTypeArray] count]; NSInteger styleRows = [rvc.scoreTypeArray objectAtIndex:indexPath.row]; ///HERE I GET AN ERROR MESSAGE SAYING THAT indexPath IS NOT DEFINED ///For Date NSInteger count = [[rvc dateArray] count]; NSInteger rows = [[rvc indexPath] row]; ///AND HERE I GET A WARNING MESSAGE SAYING rootViewController MAY NOT RESPOND TO INDEX PATH, AND OF COURSE IT DOESN'T WORK [[evc dateField] setText:[NSString stringWithFormat:@"%@", [[evc dateArray] objectAtIndex:(count-1-rows)]]]; [[evc styleField] setText:[NSString stringWithFormat:@"%@", [[rvc scoresArray] objectAtIndex:(styleCount-1-styleRows)]]]; [navigationController release]; [evc release]; [rvc release];} So here I'm trying to load the information from a saved array that is declared in my rootViewController. Any thoughts any body? Please and thank you : )

  • Default boolean value in a array of record - Delphi

    - by James
    Hi, I am helping out my company with some old delphi 7 code. There is a record declared at the start that is used throughout to store all the data we want outputted. type TOutput_Type = record result: String; resultoffset: String; selected: boolean; resultcategory: integer; end; and then an array of this is declared Output: array of TOutput_Type; The length is set at the start to a large value, as actual length is unknown. This array is used all over the place, but unfortunately the value selected is not always set when used. My problem is I am adding in a summary of the data, but because selected is not set, delphi seems to give it a random true or false status. Is there a way of setting all instances of selected as true at the start? Seems like a simple enough thing to do, but I'm not a delphi programmer so am unsure if its possible? I know I can go through and add in selected := true every time a new record is made, but I'd like to do it cleanly at the start if possible.... Thanks in advance

  • How to add default value on save form?

    - by Ignacio
    I have an object Task and a form that saves it. I want to automatically asign created_by field to the currently logged in user. So, my view is this: def new_task(request, task_id=None): message = None if task_id is not None: task = Task.objects.get(pk=task_id) message = 'TaskOK' submit = 'Update' else: task = Task(created_by = GPUser(user=request.user)) submit = 'Create' if request.method == 'POST': # If the form has been submitted... form = TaskForm(request.POST, instance=task) if form.is_valid(): task = form.save(commit=False); task.created_by = GPUser(user=request.user) task.save() if message == None: message = 'taskOK' return tasks(request, message) else: form = TaskForm(instance=task) return custom_render('user/new_task.html', {'form': form, 'submit': submit, 'task_id':task.id}, request) The problem is, you guessed, the created_by field doesn't get saved. Any ideas? Thanks

  • Get the WPMU default blog domain

    - by RobertWHurst
    I have a network of blogs that link to each other. The problem is when I want to get the primary blog's domain. I need it for things like the the target of the logo when clicked. I can't seem to find a function in WPMU the retrieves this. I can see the value I want in the wp_site table. I could easily get it with $wpdb, but its a bit over kill, and if there is a function that can get the value already, then I want to use it.

  • NSUserDefaults and default language used for I18N

    - by fedmest
    I have searched around a lot for this and found some answers that sounded quite like what I wanted but never worked. I simply need to have my iPhone app load NIBs and Localizable.strings that I decide (through user selection) rather than the ones that are established through the global iPhone/iPad settings. General consensus seems to be that this line [[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObject:@"ro"] forKey:@"AppleLanguages"]; would do the trick (in this specific case, load the NIBs and Localizable.strings in ro.lproj) but I have not had such luck. It keeps on looking for the files in en.lproj or whatever language I chose in the Settings app. I have then tried adding this line [[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObject:@"ro_RO"] forKey:@"AppleLocale"]; and to my great surprise, it worked! ...only once :-( then back to the same issue. Has anyone got any idea how to solve this issue? The aforementioned code was added at the very start of applicationDidFinishLaunching, which is before any NIBs or strings files should be loaded.

  • How to define a default tooltip style for all Controls

    - by skjagini
    I would like to define a style with a template when there are validation errors and would display the first error message as a tooltip. It works fine when targeting specific control like DatePicker in the following xaml. <Style TargetType="{x:Type ToolKit:DatePicker}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> I cannot get it to work for Control though, i.e. the following doesn't give any tooltip <Style TargetType="{x:Type ToolKit:Control}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> Any idea?

  • SSRS default renderer strips html tags

    - by stackoverflowuser
    For TFS task work item, I copy a table from ms word 2003/2007 document and paste it into the description field (supports rich text). When the task item is saved, correct formatting is saved in TFS database table. But when the same data is displayed in a SSRs report (through report manager) the formatting is lost. Probably the ssrs rendering engine is stripping off the tags. I have the "HTML-Interpret HTML tags as styles" enabled for the report field. It will be of great help if someone can provide more information on this issue and how it can be handled. Thanks.

  • How to detect default printer properties from browser?

    - by Annan
    Regardless of if this is a good idea or not, is it possible to detect printer attributes from the browser? The idea is that you want to print out a brochure that's selling something. Depending on different things such as if the printer is black&white/colour, high/low resolution, laser/inkjet, printing to a file, etc, you want to print out the page differently. For example you might choose different text colours or fonts, different image sizes, etc. My initial thoughts are: ActiveX, Flash, Java, Silverlight, browser plugins. Kudos if it's possible in javascript. I'm interested in all ways to do this, cross browser or not. Please no reasons about why this shouldn't be done ^_^

  • Populate FILE field with default text

    - by dclowd9901
    I'm trying to reutilize code that generates FILE fields for use when something is to be added to the database, and grayed out (and disabled) with data already in the database when the item in question is being edited or viewed in detail. However, I can't seem to get the text to fill the field. I'm using this: echo '<input type="file" name="small[]" value="' . $value_from_database . '" DISABLED><br>'; Am I missing anything? If not, are there any decent workarounds?

  • Was delegates static by default?

    - by Sri Kumar
    Hello All, I was just trying to understand delegates using the following code. public class delegatesEx { public delegate int Mydelegate(int first, int second); public int add(int first, int second) { return first + second; } public int sub(int first, int second) { return first - second; } } Here is my main method Console.WriteLine("******** Delegates ************"); delegatesEx.Mydelegate myAddDelegates = new delegatesEx.Mydelegate(new delegatesEx().add); int addRes = myAddDelegates(3, 2); Console.WriteLine("Add :" + addRes); delegatesEx.Mydelegate mySubDelegates = new delegatesEx.Mydelegate(new delegatesEx().sub); int subRes = mySubDelegates(3, 2); Console.WriteLine("Sub :" + subRes); I didn't declare delegate to be static but i was able to access it using the Class name. How is it possible?

  • Removing the Default Wrap Character From all records

    - by aceinthehole
    I am using BizTalk 2009 and I have a flat file that is similar to the following "0162892172","TIM ","LastName ","760 "," ","COMANCHE ","LN " "0143248282","GEORGE ","LastName ","625 "," ","ENID ","AVE " When I parse it and start mapping it I need to get rid of the quotation marks. I have marked the Wrap Character attribute for the schema as a quotation mark but it doesn't remove it when BizTalk is parsing the file. Is there an easy way to specify the removal of a wrap character or am I going to have to run it through a script functiod every time? Also I would like to be able to remove the trailing spaces as well, if at all possible.

  • Query for value where a default namespace node exists

    - by Jay
    I have the following XML that is provided to me and I cannot change it: <Parent> <Settings Version="1234" xmlns="urn:schemas-stuff-com"/> </Parent> I am trying to retrieve the "Version" attribute value using XPath. It appears since the xmlns is defined without an alias it automatically assigns that xmlns to the Settings node. When I read this XML into an XMLDocument and view the namespaceURI value for the Settings node it is set to "urn:schemas-stuff-com". I have tried: //Parent/Settings/@Version - returns Null //Parent/urn:schemas-stuff-com:Settings/@Version - invalid syntax
