  • Is converting this ArrayList to a Generic List efficient?

    - by Greg
    The code I'm writing receives an ArrayList from unmanaged code, and this ArrayList will always contain one or more objects of type Grid_Heading_Blk. I've considered changing this ArrayList to a generic List, but I'm unsure if the conversion operation will be so expensive as to nullify the benefits of working with the generic list. Currently, I'm just running a foreach (Grid_Heading_Blk in myArrayList) operation to work with the ArrayList contents after passing the ArrayList to the class that will use it. Should I convert the ArrayList to a generic typed list? And if so, what is the most efficient way of doing so?

  • Winforms StatusStrip - why are there periods where it is blank when I'm updating it???

    - by Greg
    Hi, BACKGROUND: I have a WindowForms v3.5 application with a StatusStrip set to be used as a TooStripStatusLabel. I'm issues quite a lot of updates to it during a task that is running, however there are noticable periods where it is BLANK. There are no points when I am writing a blank to the status strip label either. QUESTION: Any ideas why I would be seeing period where the status strip label is blank, when I don't expect it to be? How I update it: private void UpdateStatusStrip(string text) { toolStripStatusLabel1.Text = text; toolStripStatusLabel1.Invalidate(); this.Update(); } thanks

  • Oracle data provider hangs IIS worker process when web site is stopped

    - by Greg
    We're experiencing a nasty issue in Oracle 11g Release 2 where the w3wp process takes over and entire processor core, and debugging shows that the Oracle data provider is throwing ThreadAbortExceptions infinitely. A developer found this issue by doing the following: 1) Browse a web site that uses Oracle data connections locally (http://localhost/OracleWebSite) - we use IIS, not the ASP.NET dev server, for all of our sites. This ensures that the w3wp process is running and that an active Oracle pool of connections exists in the app pool. 2) Stop the web site (or perform a Rebuild All operation in Visual Studio on the web site in question). Our Oracle connection handling in the affected applications (all Oracle web apps) is well-established and robust. This issue does not occur if we disable connection pooling. This issue does not occur in Oracle 11g Release 1.

  • How do I rescue a small portion of data from a SQL Server database backup?

    - by Greg
    I have a live database that had some data deleted from it and I need that data back. I have a very recent copy of that database that has already been restored on another machine. Unrelated changes have been made to the live database since the backup, so I do not want to wipe out the live database with a full restore. The data I need is small - just a dozen rows - but those dozen rows each have a couple rows from other tables with foreign keys to it, and those couple rows have god knows how many rows with foreign keys pointing to them, so it would be complicated to restore by hand. Ideally I'd be able to tell the backup copy of the database to select the dozen rows I need, and the transitive closure of everything that they depend on, and everything that depends on them, and export just that data, which I can then import into the live database without touching anything else. What's the best approach to take here? Thanks. Everyone has mentioned sp_generate_inserts. When using this, how do you prevent Identity columns from messing everything up? Do you just turn IDENTITY INSERT on?

  • Modular HTML in Adobe AIR? Is It Possible?

    - by Greg Bulmash
    When I write HTML with a PHP backend, I usually have a single header file and a single footer file with some PHP variables in them. The base skeleton for every page calls the header, contains the body content, and then calls the footer. That way, if I want to make changes to the header sitewide, I change one file. I'm working on developing the UI in my first Adobe AIR app and I'm wondering if there's some way to include such files in an HTML based page template there. Obviously, with the file read/write abilities in AIR, I can write a Javascript routine to pull data from a header file, parse it, and inject it into a placeholder. It just seems like such a kludge. I'm thinking there's gotta be some simple way to import a block of HTML into a page without an iFrame or complex post-processor. Something like a PHP include statement or perhaps the old Server Side Includes. Any methods you guys can recommend?

  • what's an easier rampup: ASP.net or WCF?

    - by Greg
    Hi I'm across winforms currently but want to write an app that users will have a LAN/WAN between them and database. So assuming I need to use WCF if I stick with winforms as the UI, or go ASP.net and go web, THEN which of these two approaches would be the easier rampup approach for me? Note wanted to use Entity Framework.

  • Rails: Different prices for different branches, association depending on two other models combined

    - by Greg Lemond
    I have three models: Service has_many :prices has_many :groups, through: prices Price belongs_to :service belongs_to :group Group has_many :prices I want to have an input field (Simple_Form) for every price. In views/services/_form.html.haml I do: simple_form_for @service do |f| simple_fields_for :groups do |g| simple_fields_for :prices do |p| p.input :price With this setup I only get input fields for already saved prices. How I can get a price field for every group? I tried to do it manually, but it got really nasty and didn't work either. Thanks for any ideas!

  • QuickGraph - is there algorithm for find all parents (up to root vertex's) of a set of vertex's

    - by Greg
    Hi, In QuickGraph - is there algorithm for find all parents (up to root vertex's) of a set of vertex's. In other words all vertex's which have somewhere under them (on the way to the leaf nodes) one or more of the vertexs input. So if the vertexs were Nodes, and the edges were a depends on relationship, find all nodes that would be impacted by a given set of nodes. If not how hard is it to write one's own algorithms?

  • How to build a SQL statement when any combination of user input to the table is possible?

    - by Greg McNulty
    Example: the user fills in everything but the product name. I need to search on what is supplied, so in this case everything but productName= This example could be for any combination of input. Is there a way to do this? Thanks. $name = $_POST['n']; $cat = $_POST['c']; $price = $_POST['p']; if( !($name) ) { $name = some character to select all? } $sql = "SELECT * FROM products WHERE productCategory='$cat' and productName='$name' and productPrice='$price' "; EDIT Solution does not have to protect from attacks. Specifically looking at the dynamic part of it.

  • What's a good jQuery ligthbox plugin that cycles through images? (like a carousel)

    - by Greg
    I'm looking for a jQuery lightbox plugin that has the ability to, with it's next and previous buttons, cycle through images repeatedly. Like a carousel effect. I've been using jQuery Lightbox Plugin (balupton edition) but that doesn't have the option to continue cycling through images. It reaches the last image in the array and then disables the 'next' button. So to save me some time coding, what are some plugins you can recommend?

  • How do you programmatically set a Style on a View?

    - by Greg
    I would like to do something like this: <Button android:id="@+id/button" android:layout_width="wrap_content" android:layout_height="wrap_cotent" style="@style/SubmitButtonType" /> But in code The xml approach works fine provided that SubmitButtonType is defined. Now what I assume happens is that the appt parser runs through this xml, generates an AttributeSet. That AttributeSet when passed to context/theme#obtainStyledAttributes() will have the style ref mask anything that is not written inline in this tag. Great that's fine! Now how do we do this programmatically. Button, as well as other View types, has a constructor that has the form: <Widget>(Context context, AttributeSet set, int defStyle). So I thought this would work. Button button = new Button(context, null, R.style.SubmitButtonType); However, I am finding that defStyle is badly documented as it really should be written to be a resourceId to an attribute (from R.attrs) that will be passed to obtainStyledAttributes() as the attribute resource, and not the style resource. After looking at the code, all the view implementations seem to pass 0 as the styleRef. I don't see the harm in having it passed as both the attr and the style resource (more flexible and negligible overhead) However I might be approaching this all wrong. How do you do this in code then other than by setting each individual element of the style to the specific widget you want to style (only possible by looking a the code to see what param maps to which method or set of methods). The only way I have found to do this is: <declare-styleable> <attr name="totallyAdhoc_attribute_just_for_this_case" format="reference"> </declare-styleable> <style name="MyAlreadyExistantTheme" > ... ... <item name="totallyAdhoc_attribute_just_for_this_case">@style/SubmitButtonType</item> </style> And instead of passing R.style.SubmitButtonType as defStyle, I pass the new R.attr.totallyAdhoc_attribute_just_for_this_case. Button button = new Button(context, null, R.attr.totallyAdhoc_attribute_just_for_this_case); This works but sounds way too complicated.

  • Java copyOf method problem with an Array of Objects

    - by Greg
    elementData = Arrays.copyOf(elementData, newCapacity); Gives error: "The method copyOf(Object[], int) is undefined for the type Arrays" This was not a problem on my home computer, but at my school's it gives the error above. I'm guessing it's running an older JRE version - any workaround? Thanks

  • How to exclude rows where matching join is in an SQL tree

    - by Greg K
    Sorry for the poor title, I couldn't think how to concisely describe this problem. I have a set of items that should have a 1-to-1 relationship with an attribute. I have a query to return those rows where the data is wrong and this relationship has been broken (1-to-many). I'm gathering these rows to fix them and restore this 1-to-1 relationship. This is a theoretical simplification of my actual problem but I'll post example table schema here as it was requested. item table: +------------+------------+-----------+ | item_id | name | attr_id | +------------+------------+-----------+ | 1 | BMW 320d | 20 | | 1 | BMW 320d | 21 | | 2 | BMW 335i | 23 | | 2 | BMW 335i | 34 | +------------+------------+-----------+ attribute table: +---------+-----------------+------------+ | attr_id | value | parent_id | +---------+-----------------+------------+ | 20 | SE | 21 | | 21 | M Sport | 0 | | 23 | AC | 24 | | 24 | Climate control | 0 | .... | 34 | Leather seats | 0 | +---------+-----------------+------------+ A simple query to return items with more than one attribute. SELECT item_id, COUNT(DISTINCT(attr_id)) AS attributes FROM item GROUP BY item_id HAVING attributes > 1 This gets me a result set like so: +-----------+------------+ | item_id | attributes | +-----------+------------+ | 1 | 2 | | 2 | 2 | | 3 | 2 | -- etc. -- However, there's an exception. The attribute table can hold a tree structure, via parent links in the table. For certain rows, parent_id can hold the ID of another attribute. There's only one level to this tree. Example: +---------+-----------------+------------+ | attr_id | value | parent_id | +---------+-----------------+------------+ | 20 | SE | 21 | | 21 | M Sport | 0 | .... I do not want to retrieve items in my original query where, for a pair of associated attributes, they related like attributes 20 & 21. I do want to retrieve items where: the attributes have no parent for two or more attributes they are not related (e.g. attributes 23 & 34) Example result desired, just the item ID: +------------+ | item_id | +------------+ | 2 | +------------+ How can I join against attributes from items and exclude these rows? Do I use a temporary table or can I achieve this from a single query? Thanks.

  • Giving proper credit to a projects contributors

    - by Greg B
    I've recently been working with an opensource library for a commercial product. The opensource code is distributed from the website of the company who sells the proprietary product as a zip file. The library is a (direct) port to C# of the original library which is in Java. As such, it uses methods instead of getter/setter properties. The code contains copyright notices to the supplier of the product. The C# port was originally provided to the company by a 3rd party individual. I have modified the source to be more C# like and added a couple of small features. I want to put my version of the code out there (Google code or where ever) so that C# users of the software can benefit from a more native feeling library. How can I and/or how should I amend the copyright notice to give proper credit to The comercial owner of the original source The guy who provided the original C# port Myself and anyone else who contributes to the project in the future The source is provided under the LGPL V2.1,

  • Passing arguments to scope_procedure in searchlogic

    - by Greg
    I'd like to use searchlogic's scope_procedure feature like so class MyModelObject < ActiveRecord::Base scope_procedure :my_scope_proc, lambda { |p1, p2| { :conditions => "p1 >= #{p1} AND p2 < #{p2}" }} end Then, I am doing the search: scope = MyModelObject.search(:my_scope_proc => true) scope.all The above code obviously doesn't work because I didn't pass p1 and p2 parameters to my named scope. I can't figure out how to pass parameters to the named scope.
