  • HttpsURLConnection failing intermittently to the same URL

    - by Arkaitz Jimenez
    I think I'm experiencing the same as http://groups.google.com/group/android-developers/msg/9d37d64aad0ee357 This is Android 1.5 SDK. I happen to call several times below code(which is in a method) with the same url and it fails intermittently. When it fails, there is no exception, the stream is empty so the readConnection fails, and getResponseCode returns -1. Global caching is disabled, setDefaultUseCaches(false); I suppose there must be some kind of url connection object pool somewhere. Any idea on how can I workaround this? HttpURLConnection connection = null; try { URL url = new URL(this.url); connection = (HttpURLConnection) url.openConnection(); connection.setRequestProperty("Authorization", "basic " + Base64Coder.encodeString(user + ":" + password)); connection.setRequestProperty("User-Agent", userAgent); connection.connect(); readConnection(connection.getInputStream()); connection.disconnect(); } catch (IOException ex) { reportException(ex, connection.getResponseCode()) } catch (ParserException ex) { reportException(ex, connection.getResponseCode()) }

  • How do I set up my @product=Product.find(params[:id]) to have a product_url?

    - by montooner
    Trying to recreate { script/generate scaffold }, and I've gotten thru a number of Rails basics. I suspect that I need to configure default product url somewhere. But where do I do this? Setup: Have: def edit { @product=Product.find(params[:id]) } Have edit.html.erb, with an edit form posting to action = :create Have def create { ... }, with the code redirect_to(@product, ...) Getting error: undefined method `product_url' for #< ProductsController:0x56102b0 My def update: def update @product = Product.find(params[:id]) respond_to do |format| if @product.update_attributes(params[:product]) format.html { redirect_to(@product, :notice => 'Product was successfully updated.') } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @product.errors, :status => :unprocessable_entity } end end end

  • Should a service layer return view models for an MVC application?

    - by erg39
    Say you have an ASP.NET MVC project and are using a service layer, such as in this contact manager tutorial on the asp.net site: http://www.asp.net/mvc/tutorials/iteration-4-make-the-application-loosely-coupled-cs If you have viewmodels for your views, is the service layer the appropriate place to provide each viewmodel? For instance, in the service layer code sample there is a method public IEnumerable<Contact> ListContacts() { return _repository.ListContacts(); } If instead you wanted a IEnumerable, should it go in the service layer, or is there somewhere else that is the "correct" place? Perhaps more appropriately, if you have a separate viewmodel for each view associated with ContactController, should ContactManagerService have a separate method to return each viewmodel?

  • How do you call a method for an Objective-C object's superclass from elsewhere?

    - by executor21
    If you're implementing a subclass, you can, within your implementation, explicitly call the superclass's method, even if you've overridden that method, i.e.: [self overriddenMethod]; //calls the subclass's method [super overriddenMethod]; //calls the superclass's method What if you want to call the superclass's method from somewhere outside the subclass's implementation, i.e.: [[object super] overriddenMethod]; //crashes Is this even possible? And by extension, is it possible to go up more than one level within the implementation, i.e.: [[super super] overriddenMethod]; //will this work?

  • Common Utility for Exception Searching

    - by Andrew
    I wrote this little helper method to search the exception chain for a particular exception (either equals or super class). However, this seems like a solution to a common problem, so was thinking it must already exist somewhere, possibly in a library I have already imported. So, any ideas on if/where this might exist? boolean exceptionSearch(Exception base, Class<?> search) { Throwable e = base; do { if (search.isAssignableFrom(e.getClass())) { return true; } } while ((e = e.getCause()) != null); return false; }

  • Getting repeat values after copying 2-3 items to clipboard in android?

    - by Gurpreet singh
    I am using clipboard code like below in my app.Everything is working fine if i copy one item at a time.But when we copy 2-3 items one after other and paste somewhere it starts retrieving repeated past value from clipboard rather than the current value.After googling a lot i came to know that its a problem with Samsung phones and i need to clear clipboard history for that.But i could not find any way to clear clipboard history. Public void CopyToClipboard { int pos = (Integer) v.getTag(); StatusEntity obj=getItem(pos); ClipboardManager clipmanager= (ClipboardManager)getContext().getSystemService(getContext().CLIPBOARD_SERVICE); ClipData clip=ClipData.newPlainText("data",obj.getStatus()); clipmanager.setPrimaryClip(clip); Toast.makeText(getContext(), "Copied to clipboard", 1000).show(); } Hoping that anyone of you can help me regarding this .Any help would be appreciated.

  • Possible loss of precision / [type] cannot be dereferenced

    - by Samuel
    I have been looking around a lot but i simply can't find a nice solution to this... Point mouse = MouseInfo.getPointerInfo().getLocation(); int dx = (BULLET_SPEED*Math.abs(x - mouse.getX()))/ (Math.abs(y - mouse.getY()) + Math.abs(x - mouse.getX()))* (x - mouse.getX())/Math.abs(x - mouse.getX()); In this constellation i get: Possible loss of precision, when i change e.g (x - mouse.getX()) to (x - mouse.getX()).doubleValue() it says double cannot be dereferenced, when i add intValue() somewhere it says int cannot be dereferenced. What's my mistake? [x, y are integers | BULLET_SPEED is a static final int] Thanks!

  • Shortcut icon for registered file types in visual studio setup project

    - by Zenya
    It is known that when you create a shortcut and place it in the desktop or program menu directory in a VS setup project, you should also set an icon for it. If not, the default icon will be displayed. However it is natural to think that icons to the files of the registered type (such as pdf, txt, doc, etc.), should be taken from the OS after installation. What I want: What I get: How to implement this? PS: Of course, I can get the pdf and txt icons from somewhere, add them to the VS project and set to the shortcuts, but I believe that there should be a better solution.

  • Setting SqlParameter value automatically with DataGridView?

    - by johansson
    Is there a way to set a SqlParameter's value with DataGridView, if data-bound? For example: SqlCommand selCmd = CreateCommand("SELECT * FROM table1"); SqlCommand updCmd = CreateCommand("UPDATE table1 Set column1 = @column1 WHERE id = @id"); updCmd.Parameters.Add(new SqlParameter("column1"), SqlDbTypes.Int)); updCmd.Parameters.Add(new SqlParameter("id", SqlDbTypes.Int)); SqlDataAdapter da = new SqlDataAdapter(); da.SelectCommand = selCmd; da.UpdateCommand = updCmd; da.Fill(_dataTable); dgv.DataSource = _dataTable; Then somewhere later: da.Update(); How can I make sure it's getting the right column1 value that was edited and the right id for the row for the da.Update(); to work, otherwise it complains that I have not provided the value. Or if there's a better way, please advise. Thanks!

  • How to fetch, display Amazon Marketplace listings by item?

    - by Matt G.
    Hi all, My question pretty much says it all: I'm looking for a way to display Amazon Marketplace listings based on an item lookup. Example: If I do a call to ItemLookup with an ASIN of 0590353403 (Harry Potter and the Sorcerer's Stone), I'm looking for a result set of perhaps the top ten new or used Marketplace listings, preferably with seller information attached. I apologize if this is clearly documented somewhere, but I have been looking all through the Amazon API docs and on Google to no avail. StackOverflow doesn't seem to have any Related Questions that match what I'm asking, either. Thanks in advance!

  • Dynamically generating a file with javascript?

    - by gct
    I'm working on a web app for my company that will let us do some image tagging stuff, and I'd like to be able to generates results in the form of a CSV file. I can do this easily enough by dumping the CSV data to a div or something on the page and having the user copy it out. I'd rather have them hit the a generate button and have a CSV file downloaded as though they clicked on a link to the result, so they can more easily just save the file somewhere convenient. Is it possible to simulate this kind of thing with javascript? I basically want to dynamically generate the file and then let them download it, client side.

  • mysql multiple where and inner join query combination

    - by bandhunt
    I'm a little lost as how to run two mysql queries as one(return one result set to be sorted etc). I understand how to do multiple JOINS but need to combine the below which is more than just a multiple join - it would include a multiple where etc. 1st query sql = "SELECT s.id, s.song_name FROM `songs` as s INNER JOIN `artists` as a ON s.artist_id = a.id WHERE ((`a`.id = #{search}))" 2nd query sql = "SELECT s.id, s.song_name FROM `songs` as s INNER JOIN `similarments` as si ON s.artist_id = si.artist_id WHERE ((`si`.similar_id = #{search}))" And then run both queries at once so I can ORDER them etc. Or combine them as one big query (maybe put an OR somewhere)? Thanks!

  • Dismiss Menu when Focus is lost, not on mouseout. jQuery

    - by Stacey
    I have jQuery that drops a menu down when its parent is clicked on, and dismisses it when they hover away from the menu. I am wanting to change the behavior so that it only dismisses if they click somewhere else on the page, or a different menu. Is this possible? jQuery.fn.dropdown = function () { return this.each(function () { $('.ui-dropdown-list > li > a').click(function () { $(this).addClass("ui-dropdown-hover"); }); $("ul.ui-dropdown-list > li > a").click(function () { $(this).parent().find("ul").show(); $(this).parent().hover(function () { }, function () { $(this).parent().find("ul").hide(); $(this).find('> a').removeClass("ui-dropdown-hover"); }); }); }); };

  • Make C# source run as a script?

    - by acidzombie24
    I am doing a little scripting and i find some more power would be nice. Like the ability to keep trying to delete a file with a 1sec delay AND have it portable since i spent some time today translating a bat script to bash. I know i can use php or python but i VERY MUCH PREFER static/compile time checking. Is there a way to run C# code as a script? I am hoping i dont have to create a custom ext and write a app to dynamically compile and execute the script (i know have source to compile .js somewhere...). Does anyone know of a solution?

  • Find value within a range in lookup table

    - by francis
    I have the simplest problem to implement, but so far I have not been able to get my head around a solution in Python. I have built a table that looks similar to this one: 501 - ASIA 1262 - EUROPE 3389 - LATAM 5409 - US I will test a certain value to see if it falls within these ranges, 389 -> ASIA, 1300 -> LATAM, 5400 -> US. A value greater than 5409 should not return a lookup value. I normally have a one to one match, and would implement a dictionary for the lookup. But in this case I have to consider these ranges, and I am not seeing my way out of the problem. Maybe without providing the whole solution, could you provide some comments that would help me look in the right direction? It is very similar to a vlookup in a spreadsheet. I would describe my Python knowledge as somewhere in between basic to intermediate. Many thanks in advance.

  • How do I not include part of a regular expression

    - by Axilus
    I'm pretty new to using regexes and I can figure out how I would go about extracted a specific number from a string. Suppose the string was any amount of whitespace or random text and somewhere within it is this, "Value: $1000.00." In order to retrieve that value I am currently using this: string value = Convert.ToString(Regex.Match(BodyContent, @"Value:[ \t]*\$?\d*(\.[0-9]{2})?", RegexOptions.Singleline)); So the variable 'value' now has, "Value: $1000.00" stored in it. My question is, using Regex is there a way to use 'Value:' to find the number value but only store the actual number value (i.e. 1000.00) in the 'value' variable?

  • How can i connect two or more machines via tcp cable to form a network grid?

    - by Gath
    How can i connect two or more machines to form a network grid and how can i distribute work load to the two machines? What operating systems do i need to run on the machines, and what application should i use to manage the load balancing? NB: I read somewhere that google uses cheap machines to perform this fete, how do they connect two network cards( 'Teaming' ) and distribute load across the machines? Good practical examples would serve me good, with actual code samples. Pointers to some good site i might read this stuff will be highly appreciated.

  • Dynamic binary from file

    - by Aurel300
    This is a little bit of weird problem here. Say I have a C++ code, running on a specific platform. The only purpose of this code is to run files containing binary, NATIVE to that platform. Now - my question is - HOW would I get the data from these files (could even be by bits, like 1024 bits a cycle) to the memory of machine running my code so that this data would be in the execution part? In other words, can I get the data to somewhere where I can point the instruction pointer? If yes, how? I don't mind if I have to use assembler for this - just so it would work.

  • Storing Object Types in Variable then Initializing

    - by Jon Mattingly
    Is there a way in Objective-C to store an object/class in a variable to be passed to alloc/init somewhere else? For example: UIViewController = foo foo *bar = [[foo alloc] init] I'm trying to create a system to dynamically create navigation buttons in a separate class based on the current view controller. I can pass 'self' to the method, but the variable that results does not allow me to alloc/init. I could always import the .h file directly, but ideally I would like to make reusing the code as simple as possible. Maybe I'm going about this the wrong way?

  • Modifying a .swf file

    - by user3015196
    I am really stuck with modifying a .swf file. I just downloaded a SWF file somewhere and I want to remove all objects and animations - everything except the logo ripple effect. How can I do that? Or is it impossible? I didn't work with Flash before and this is my first time. Can you help me with that? If not, could I just get some hints or a demo on how I can do that? Here is a link to a demo. I just want the logo animation and nothing else.

  • Bringing specific results to the front using one MySQL query.

    - by animuson
    I'm setting up my geolocation feature which lists out all the countries in order of name. However, most websites have it set up where the popular countries (such as United States, United Kingdom, Canada, Australia) are at the front of the list (are shown first rather than in their assigned places). Is it possible to achieve this using the same MySQL query that I am already running to select them? SELECT * FROM `global_flags` ORDER BY `country` Is there a better alternative somewhere? Perhaps something that can reorganize the results after the database has already been queried? I don't want to exclude those results and then manually type them at the beginning because that would waste more space in the file.

  • .htaccess stupid issue

    - by justnoone
    I have a server where I can only configure httpd using .htaccess, a cannot access global configuration. I want to rewrite almost every non-existing path to index.php, so I did something like: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?path=$1 [L,QSA] And that is ok. But another thing I want to do is to prevent access to path where I keep PHP files (I cannot store them somewhere else) which is for example /php. I would like that anything starting with /php rewrites to index.php?path=php... so I did something like: RewriteCond %{REQUEST_URI} ^/php.* RewriteRule ^(.*)$ /index.php?path=$1 [L,QSA] And that also would work ok if I had access to global configuration. In case of per-directory configuration, when I access /php it rewrites it to index.php?path=php and than puts directory name before that: /php/index.php?path=php. I read documentation and I realize that it uses internal redirects when per-directory confoguration is used. How can I avoid this behavior?

  • How can I listen for the deletion of a ProjectItem via DTE?

    - by Will
    I've got a designer that relies on the existence of other solution items. If one of those items is deleted the designer crashes and you have to edit as XML to fix. Not exactly user friendly. I do, however, have the DTE object representing the instance of Visual Studio, as well as the ProjectItems I am dependent on. Is it possible to, somewhere in the depths of the DTE, register a listener for the deletion of that ProjectItem? And, if so, How would I do it?
