  • Drop Down Box (select) set URL on postback?

    - by jamone
    I have a page with a ASP.NET DropDownBox control (HTML select) that's populated with some dynamic record values. When the user selects a record the entire contents of the page is updated to reflect the selection. If a user clicks a link and leaves the page and tries to go back, it pulls up the default unselected list, and they have to reselect it again. How would be the best way to retain their selection? I currently have the page set so if the url contains PageName.aspx?recordID=5 it will select the correct dropDown option. However I'm not sure how to change the URL's query string based on the selection.

  • iOS get file size on disk

    - by F2_CMD
    I'm trying to get the size on disk of a file in iOS using Objective C. As of now I've been able to get the actual size of the file and other file information using NSFileManager and then getting the attributes attributesOfItemAtPath:error but not the size on disk. I also tried getting the file size from struct stat but again it doesn't give me size on disk.I tried using NSTask to make a call to du -h but iOS didn't allow me to fork other processes. Any ideas are welcome :) I know this questions is similar to many others but the difference is that I'm trying to do this in iOS and most of the methods used in other systems don't work here. Thanks

  • What is the best way to store categorical references in SQL tables?

    - by jlafay
    I'm wanting to store a wide array of categorical data in MySQL database tables. Let's say that for instance I want to to information on "widgets" and want to categorize attributes in certain ways, i.e. shape category. For instance, the widgets could be classified as: round, square, triangular, spherical, etc. Should these categories be stored within a table to reference them best from an application? Another possibility, I would imagine, would be to add a column to widgets that contained a shape column that contained a tiny int. That way my application could search shapes by that and then use a coordinating enum type that would map the shape int meanings. Which would be best? Or is there another solution that I'm not thinking of yet?

  • Gtting X-windows error while runing gtk application.

    - by PP
    I have written one gtk application but i am getting following X Windows error while running it: The program 'TestApp' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 222 error_code 8 request_code 2 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) What might be the cause of this error? I have written this app in GTK+ and C. Thank, PP.

  • iPhone: Grouping records in multiple UITableView views

    - by Nic Hubbard
    Let me first say, I know how to create sections and group records within a UITableView. What I am wanting to do is something similar to creating a photo album. So, I have all my data objects coming from core data, and, I want to be able to create a custom group, such as "My Trip to Mexico" and "First Birthday". Then, the user should be able to add objects/records into new sections/albums. So, basically the user is creating custom sections with their own custom names, and then choosing what records should go into that section/album. So, I am just wondering what is the best way to do this? I am thinking that I would just create some extra attributes for my core data model. Or, would I create a whole new "Album Section" object, and somehow use that? Point me in the right direction. :)

  • On Memory Allocation and C++

    - by Arpan
    And I quote from MSDN http://msdn.microsoft.com/en-us/library/aa366533(VS.85).aspx: The malloc function has the disadvantage of being run-time dependent. The new operator has the disadvantage of being compiler dependent and language dependent. Now the questions folks: a) What do we mean that malloc is run-time dependent? What kind of dynamic memory allocation functions can be independent of run-time? This statement sounds real strange. b) new is language dependent? Of course it should be right? Are HeapAlloc, LocalAlloc etc language independent? c) From a pure performance perspective are the MSVC provided routines preferable? Arpan

  • Possible to bind an event listener to a (hypothetical) onChangeInnerHTML event?

    - by DustMason
    In my app, I have an OL tag whose contents are changed by various other dynamic events. Is there some way to put a listener on that OL so that I can execute a function whenever its contents are altered in any way? In this example I need to update a count of items in the list which appears in another spot in the interface. I am using jQuery if that helps. The contents of the OL are being changed with OL.append() and LI.remove(), in case those methods have some special events that I don't know about Thanks!

  • Best method of Zend Framework caching

    - by iamthejeff
    I have a blog built using Zend Framework, which I realize might be a bit overkill for a blog alone, but I am planning on adding other features in the future. Nevertheless, I've noticed pages could be a little speedier. I've done a basic caching method that basically captures everything in index.php (Core frontend and File backend), which works great, but unfortunately it also prevents dynamic page contents from updating (messages like "this was posted 5 minutes ago", etc) until the cache period expires. So my question is what would be the best method of caching to improve performance? I am doing fairly basic queries which are mostly simple selects, not many joins or anything fancy (using Zend_Db_Table), and even on a small database page loads are a little sluggish. Is it worth it to cache queries or should I focus my time elsewhere?

  • Is there any Python library that allows me to parse an HTML document similar to what jQuery does?

    - by Sachin Tendulkar
    Is there any Python library that allows me to parse an HTML document similar to what jQuery does? i.e. I'd like to be able to use CSS selector syntax to grab an arbitrary set of nodes from the document, read their content/attributes, etc. The only Python HTML parsing lib I've used before was BeautifulSoup, and even though it's fine I keep thinking it would be faster to do my parsing if I had jQuery syntax available. :D Write an iterative program that finds the largest number of McNuggets that cannot be bought in exact quantity. Your program should print the answer in the following format (where the correct number is provided in place of n): "Largest number of McNuggets that cannot be bought in exact quantity: n"

  • copy child collection to another object

    - by Bogdan
    Hi everyone, I have a one-to-many relationship between Part and Params (a "Part" has many "Params). I'm trying to do something naive like this: Part sourcePart = em.find(Part.class, partIdSource); Part destPart = em.find(Part.class, partIdDest); Collection<Param> paramListSource = sourcePart.getParamList(); destPart.setParamList(paramListSource); Basically I want to copy all the parameters from sourcePart to destPart. Hopefully the persistence provider will automatically set the right foreign keys in the Param table/entity. The above code will obviously not work. Is there any easy way of doing this, or do I have to do create a new collection, then add each Param (creating new Param, setting attributes, etc) ?

  • Trying to create a RegEx for the following patterns

    - by Travis
    Here are the patterns: Red,Green (and so on...) Red (+5.00),Green (+6.00) (and so on...) Red (+5.00,+10.00),Green (+6.00,+20.00) (and so on...) Red (+5.00),Green (and so on...) Each attribute ("Red,"Green") can have 0, 1, or 2 modifiers (shown as "+5.00,+10.00", etc.). I need to capture each of the attributes and their modifiers as a single string (i.e. "Red (+5.00,+10.00)", "Green (+6.00,+20.00)". Help?

  • JButtons re-enable themselves after being disabled

    - by Anarchist
    I have an array of JButtons which form a keypad interface. After six numbers are entered I want to disable the keypad so that no further numbers can be entered by the user. I have written the code and the buttons do disable until the mouse hovers above any of them, then the buttons seem to re-enable themselves and run actionEvents added to them. The full code is available here. Possible things that I think are wrong. There is some sort of MouseListener which is ignoring when I set button.setEnabled(false); I haven't separated attributes from the buildGUI(); correctly, I only did this anyway so that the inner class could access them. Possibly something to do with the gridLayout as disabling the buttons seems to work for my services JPanel buttons.

  • How to specify a child element in XML schema with a name but any content?

    - by mackenir
    I am trying to write some XML schema code to specify that a particular element 'abc' may have a child element with name 'xyz', and that element may have any attributes, and any child elements. At the moment I have this: <xs:element name="abc"> <xs:complexType> <xs:sequence> <xs:element name="xyz"> <xs:complexType> <xs:sequence> <xs:any/> </xs:sequence> <xs:anyAttribute/> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> But when I validate my XML against the schema, I get validation failures complaining about the child elements of the xyz element.

  • Invoking a superclass's class methods in Python

    - by LeafStorm
    I am working on a Flask extension that adds CouchDB support to Flask. To make it easier, I have subclassed couchdb.mapping.Document so the store and load methods can use the current thread-local database. Right now, my code looks like this: class Document(mapping.Document): # rest of the methods omitted for brevity @classmethod def load(cls, id, db=None): return mapping.Document.load(cls, db or g.couch, id) I left out some for brevity, but that's the important part. However, due to the way classmethod works, when I try to call this method, I receive the error message File "flaskext/couchdb.py", line 187, in load return mapping.Document.load(cls, db or g.couch, id) TypeError: load() takes exactly 3 arguments (4 given) I tested replacing the call with mapping.Document.load.im_func(cls, db or g.couch, id), and it works, but I'm not particularly happy about accessing the internal im_ attributes (even though they are documented). Does anyone have a more elegant way to handle this?

  • Relational databases are not suited for my application - what's the alternative?

    - by waitinforatrain
    Hi, I'm writing a CMS in PHP that allows the user to define different fields (e.g. a Blog page could have fields for Title (string), Content (rich text), Picture (file)). I need the user to be able to add and remove fields dynamically, and the only way I can think of to do it with relational DBs is to serialise all these values and store them in one cell. This seems like a slow approach and like I'm trying to fit something dynamic within a static structure. Could someone recommend anything that is PHP-compatible that would make this easier?

  • How to Generate Embeddable Widgets, and Return PartialView, JS & CSS as JSONP?

    - by DaveDev
    I found this question which is a great starting point towards creating embedded widgets that enable showing dynamic content on remote sites (i.e. a different domain). One problem I'm having is with the following code: public ActionResult SomeAction() { return new JsonpResult { Data = new { Widget = "some partial html for the widget" } }; } It says Widget = "some partial html for the widget" but this doesn't really mean anything to me. I assume that Widget would contain the HTML representing what the user wants to see on the screen, but How do I get the contents of my Partial View into Widget? Can anyone point me in the right direction? Thanks..

  • Dynamically adding a Button to a PlaceHolder in a DataGrid

    - by hrnt
    I have basically something like this: <asp:datagrid id="DGrid" runat="server" AutoGenerateColumns="false"> <asp:TemplateColumn HeaderText="Stuff"> <ItemTemplate> <asp:PlaceHolder id="PH" runat="server" /> </ItemTemplate> </asp:TemplateColumn> </asp:datagrid> I need to add a Button to the PlaceHolder depending on the values of the data I am binding. At the moment I am adding the Button after the data is bound in Page_Load. The problem is that the data binding methods are not called in postbacks, so the Button disappears when I click on it. Any suggestions on how to do this? Problem is that I need to know some attributes of the grid item to create the Button, so I cannot create it before the data has been bound.

  • Rails fixtures seem to be adding extra unexpected data

    - by Mason Jones
    Hello, all. I've got a dynamic fixture CSV file that's generating predictable data for a table in order for my unit tests to do their thing. It's working as expected and filling the table with the data, but when I check the table after the tests run, I'm seeing a number of additional rows of "blank" data (all zeros, etc). Those aren't being created by the fixture, and the unit tests are read-only, just doing selects, so I can't blame the code. There doesn't seem to be any logging done during the fixtures setup, so I can't see when the "blank" data is being inserted. Anyone ever run across this before, or have any ideas of how to log or otherwise see what the fixture setup is doing in order to trace down the source of the blank data?

  • Reporting. MS Word templates population required

    - by Andrew Florko
    Application we developed fills MS Word templates with data from Database. Customers require to have ability edit Word templates via MS Word (change style, font, layout e.t.c) with no additional software to be installed and no training. AFAIK, Sql Reporting Services and Crystal Reports can't populate MS Word templates produced in MS Word. So we implemented our custom solution that maps .net classes onto xml-saved MS Word documents. It looks like we declare class MyTemplate { // maps to [age] field declared in ms document straight in the text int Age { get; set; } // maps to table by attributes applied to property (omitted) List<Person> Persons { get; set; } } We also implemented images insertion. Are there any free libraries for this task or may be you use your own MS-word templators in your projects?

  • How do I pass a Yahoo Pipes item into a YQL query?

    - by Joe Shaw
    One common thing to want to do in the Yahoo Pipes YQL element is pass in a Pipes value to the YQL query. For example: select * from html.tostring where url='<someurl>' and xpath='//div[@id="foo"]' and you want to pass in a dynamic value for <someurl>. Let's say that it's an RSS feed item's URL called item.link. Attempting to simply replace the quoted someurl with item.link gives you this error: Invalid identifier item.link. me is the only supported identifier in this context How can I pass this value in?

  • m:n relationship must have properties?

    - by nax
    I'm doing a E/R model for a project. I finished the ER model and, for me, all is okay. Maybe not perfect, but it's okay. When I gave the ER model to my teacher, he told me this: "the m:n relations MUST HAVE some properties" He said if the m:n relationship doesn't have the properties it will be wrong. In my opinion m:n doesn't need forcer attributes to the relationship, but if you have someone that can fit in it, just put there. What do you think? Who is wrong in this, me, or my teacher? NOTE: Reading again, it seems what he said was not due to my ER diagram, but was a general statement. The diagram I gave him doesn't have relations yet, so there where just entities and atributes.
