• Connect to an elevated COM server from a non-elevated process

  - by JS Bangs

  We have a program which launches a child process that hosts a local COM server, which for various reasons must be launched elevated. Everything works fine so long as both the parent and the child process are elevated. However, we also want to run when the parent process is non-elevated. Launching the child process results in a UAC dialog (which is acceptable), and the child appears to start correctly and successfully calls CoRegisterClassObject. However, the parent process gets REGDB_E_CLASSNOTREG when calling CoCreateInstance with the same CLSID. I assume this is some sort of permissions issue. How can I register my class in the elevated server to allow it to be called from a non-elevated process.

• Is there anyway to reduce IsolatedStorage capacity in Silverlight?

  - by Edward Tanguay

  With this code I can have Silverlight ask the user if he wants to increase IsolatedStorage: private void Button_IncreaseIsolatedStorage_Click(object sender, RoutedEventArgs e) { IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication(); long newStorageCapacityInBytes = FileHelpers.GetMaxiumumSpace() + SystemHelpers.GetAmountOfStorageToIncreaseWhenNeededInBytes(); store.IncreaseQuotaTo(newStorageCapacityInBytes); Message = "IsolatedStorage increased. " + FileHelpers.GetSpaceLeftMessage(); } But if I try to set it to an amount less than it current is, I get an error that this is not possible. 1. Is there a workaround for this, i.e. can I reduce the amount of IsolatedStorage? 2. When the user agrees to increasing IsolatedStorage, can other applications use this capacity or just the application in which he increased it?

• Machine learning in OCaml or Haskell?

  - by griffin

  I'm hoping to use either Haskell or OCaml on a new project because R is too slow. I need to be able to use support vectory machines, ideally separating out each execution to run in parallel. I want to use a functional language and I have the feeling that these two are the best so far as performance and elegance are concerned (I like Clojure, but it wasn't as fast in a short test). I am leaning towards OCaml because there appears to be more support for integration with other languages so it could be a better fit in the long run (e.g. OCaml-R). Does anyone know of a good tutorial for this kind of analysis, or a code example, in either Haskell or OCaml?

• I have a filter for jquery masonry - but I want to filter moomasonry

  - by Jason

  Hi, I'm using jquery masonry for layout. But I am considering moving to mootools. I have found a masonry port to mootools, called moomasonry - http://www.crionics.com/products/opensource/mooMasonry/Demos/basic.html With help here, I have a filter on the masonry divs by class: $('a.filter').click(function(){ filterBoxes(this.id); }) function filterBoxes(klass){ if (klass == "all") { klass = "box" } $('#holder').find('.' + klass) .hide() .appendTo('#main') .fadeIn('200') $('#main').find('.box:not(.' + klass + ')') .fadeOut( '200', function(){ $(this).appendTo('#holder') ; }); setTimeout(function(){ $('#main').masonry() },500); } But, how would I filter divs by class in mootools? and have it reload masonry after each filter. See my site for example: http://jasondaydesign.com/masonry_demo/

• iPhone Pong Advanced Deflection Angle

  - by CherryBun

  Hi, I am currently developing a simple Pong game for the iPhone. Currently using CGRectIntersectsRect for the collision detection and as for the deflection of the ball when it hits the paddle, I just multiply the ball velocity with -1 (therefore reversing the direction of the ball). What I am trying to do is to make it so that when the ball hits the paddle, it checks whether how far is the ball from the center of the paddle, and increases the deflection angle the further the ball is away from the center of the paddle. (E.g. In this case, the ball will be deflected back at 90 degrees no matter where it came from, as long as it hits the center of the paddle) How am I suppose to do that? Any help would be greatly appreciated. Thank you.

• Tool(s) to lower the friction of programming against Interfaces in Visual Studio C#?

  - by John

  Hi I am a relatively new user of Visual Studio and I am trying "program against interfaces". I can see that when I create a class I can "Extract Interface" from the Refactor menu but you seem to only get one shot at this. ie. If I add a read only property FullName to my Customer class I would like to be able to right click and update the interface. At the moment I can only create a new interface from the Refactor menu. I want to update the interface I have already created not create new one. So the kind of tool I would be looking for would display check boxes for all valid members of the class with those already in the interface checked. It would also be handy to be able to to create the initial interface file in a different project (in the same solution), and for the tool to keep track of this. Does such a tool / add in / menu item exist (other than Ctrl C / V)? Thanks, John

• Specialization hierarchy in a domain-model

  - by devoured elysium

  I'm trying to make the domain model of a management system. I have the following kinds of persons in this system: employee manager top mananger I decided to define a User, from where employee, manager and top manager will specialize from. What I don't know is what kind of specialization hierarchy I should choose from. I thought of two ways: or Which might be preferable and why? As a long time coder, every time I try to do a domain-model, I have to fight against the idea of trying to think in how I'm going to code this. From what I've understood, I should not think about those matters in the domain-model, only in object relationships. I don't have to think of code duplication or any of these kind of details here, so I can't really pick any of the options over the other. Thanks

• CodeIgniter based e-shop, shipping and gift address design problem

  - by alexander

  While building an ecommerce platform I have run into design problems. I'm working with the built-in CodeIgniter's cart class. It stores all the cart information in session. Let say that cart has already been filled with products and user clicks checkout. When should I store order in database? Just after that click or after several steps of gathering information and stoing it in session? How to deal with additional features like different shipping methods? Should I add it to the basket first and get additional (gift address) to session? I dont want to store it in database because of the relation between gift address and order is needed and since I dont know what's the ID of the order. I'm puzzled :) Additionally I think its crucial to keep cart aware of shipping methods and additional bought services (by selecting gift address there is an extra fee) because the cart content is just like an reciept? In brief, what is the best practice to process checkout?

• jQuery .queue() not working as expected

  - by Andrew

  The page in question is right here: http://s289116086.onlinehome.us/lawjournaltv/index.php I'm 90% of the way there, I'm just assuming there's an error with my syntax. Focus on the blue callout area with "Workers' Compensation" as the title: Basically, I've created a little slideshow there with the controls at the top and when you click on any of them both the callout and the background are to slide. As you can see it's working now, but the problem is that I want the new background to slide in over the old one. I've tried several things including the queue() method, delay(), and adding everything else to the animate() callback with no success (right now the background goes black and then the new image slides in). You guys have never let me down before, so I'm hoping this is an easy fix. Thanks in advance!

• Routing configuration in cakephp

  - by ShiVik

  Hello all I am trying to implement routing in cakephp. I want the urls to mapped like this... www.example.com/nodes/main - www.example.com/main www.example.com/nodes/about - www.example.com/about So for this I wrote in my config/routes.php file.. Router::connect('/:action', array('controller' => 'nodes')); Now, I got the thing going but when I click on the links, the url in browser appears like www.example.com/nodes/main www.example.com/nodes/about Is there some way where I can get the urls to appear the way they are routed? Setting in .htaccess or httpd.conf would be easy - but I don't have access to that. Regards Vikram

• Importing large datasets on iPhone using CoreData

  - by Matthes

  Hi there, I'm facing very annoying problem. My iPhone app is loading it's data from a network server. Data are sent as plist and when parsed, it neeeds to be stored to SQLite db using CoreData. Issue is that in some cases those datasets are too big (5000+ records) and import takes way too long. More on that, when iPhone tries to suspend the screen, Watchdog kills the app because it's still processing the import and does not respond up to 5 seconds, so import is never finished. I used all recommended techniques according to article "Efficiently Importing Data" http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Conceptual/CoreData/Articles/cdImporting.html and other docs concerning this, but it's still awfully slow. Solution I'm looking for is to let app suspend, but let import run in behind (better one) or to prevent attempts to suspend the app at all. Or any better idea is welcomed too. Any tips on how to overcome these issues are highly appreciated! Thanks

• Seemingly normal link does not work in MVC, IIS5, SparkView.

  - by Matt W

  I have a regular link being generated in MVC1.0 as: /Login/Logout This link does not work. The code for it is: <a href="${Links.Logout}" class="SignOut">Sign out</a> As I am using SparkView. I am using IIS5.1 on WinXP Pro. I cannot work out why the link on the page calls the MVC action if I open the link in a separate browser tab but not when I click directly on it in the original page. This feels like a browser bug (Chrome, Firefox, IE8) but they all perform the same way. Thanks, Matt.

• Clustered index dilemma - ID or sort?

  - by richardtallent

  I have a table with two very important fields: id INT identity(1,1) PRIMARY KEY identifiersortcode VARCHAR(900) My app always sorts and pages search results in the UI based on identifiersortcode, but all table joins (and they are legion) are on the id field. (Aside: yes, the sort code really is that long. There's a strong BL reason.) Also, due to O/RM use, most SELECT statements are going to pull almost every column. Currently, the clustered index is on id, but I'm wondering if the TOP / ORDER BY portion of most queries would make identifiersortcode a more attractive option as the clustered key, even considering all of the table joins going on. Inserts on the table and changes to the identifiersortcode are limited enough that changing my clustered index would be a problem for insert/update operations. Trying to make the sort code's non-clustered index a covering index (using INCLUDE) is not a good option. There are a number of large columns, and some of them have a lot of update activity.

• C# Drawing Oracle Spatial Geometries

  - by Keeper

  I need to create a simple app which can display geometries from Oracle Spatial in C#. These geometries are exported from AutoCAD Map 3D 2010 to Oracle Spatial. I need to pan, zoom, manage layers of these objects, events (like right click to popup a contextual menu, potentially different for every object), creating/deleting points (maybe also other polygons): a sort of simple AutoCAD interface. Should I look for an AutoCAD OEM license? Is there a drawing framework which can handle this or do I need to create my own?

• jqueryForm and empty uploads

  - by Aiden Bell

  Hi All, Been scratching my head for too long on this: Using jquery.form, (http://malsup.com/jquery/form) with PHP ... my $_FILES['someimage'] gets set but the error number is always UPLOAD_ERR_NO_FILE, size is also 0. The JavaScript: $('form input[type=file]').change(function(){ $(this).clone().appendTo('#imgform'); $('#imgform').ajaxForm(); $('#imgform').ajaxSubmit( { type:'POST' } ); }); Which appends to: <form id="imgform" method="POST" action="/api/images.php" enctype="multipart/form-data"></form> From another form which has bog-standard file inputs. PHP logs are clean, but var_dumping $_FILES always shows that the index is set to the name of the form element ... but no data. Thanks guys! (Sorry, I know jQuery-like questions are too frequent round these parts).

• Log4Net and GAC - How to reference Configuraition Files?

  - by Adam

  Hello all I am using log4net during my development, as as part of a project constraint, I now need to add it to the Global Assembly Cache. The logging definitions are in a file Log4Net.xml. That file is referenced in my assemblyinfo as: [assembly: log4net.Config.XmlConfigurator(ConfigFile = "Log4Net.xml", Watch = true)]. So long as the xml file was in the same directory as the log4net.dll, everything has been working fine. However now that I've added log4net to the GAC, it is no longer picking up the xml file. Does anyone know what I need to change in order to have it pick up the XML file again? Is hardcoding the patch in the assembly reference the only way? Many thanks

• ASP.NET MVC: Problem generating thumbnails...need help!

  - by Ryan Pitts

  Ok, so i'm new to asp.net mvc and i'm trying to make a web application photo gallery. I've posted once on here about this issue i am having of trying to generate thumbnails on-the-fly on the page instead of the actual full-size images. Basically, the functionality i am looking for is to be able to have thumbnails on the page and then be able to click the images to see the full-size version. I am pulling the images and images info from an XML file. So, i did this so i could display them dynamically and so it would be easier to make changes later. Later, i am going to add functionality to upload new images to specific galleries (when i figure out how to do that as well). I am providing a link to download the project i am working on so you can see the code. I would appreciate any help with this! Thanks! URL to project: http://www.diminished4th.com/TestArtist.zip Ryan

• How do you change the subdocument location in a Word 2007 master document programmatically?

  - by boost

  We have had the unenviable happen: various master documents refer to sub-documents that are no longer where they used to be due to a directory renaming. Is there a programmatic way of tweaking the HYPERLINK field without losing the master/sub-document relationship? I've got this far ... Sub FixyaLinks() Dim s 'As String Dim i As Long Dim bTrackRevFlag As Boolean Dim bShowRevFlag As Boolean bTrackRevFlag = ActiveDocument.TrackRevisions bShowRevFlag = ActiveDocument.ShowRevisions ActiveDocument.TrackRevisions = False ActiveDocument.ShowRevisions = False For i = 1 To ActiveDocument.Fields.Count s = ActiveDocument.Fields.Item(i).Code.Text If InStr(s, "CURRICULUM\\NEW") Then s = Replace(s, "NEW Foundation Units-in developing", "Foundation Programme Units") ActiveDocument.Fields.Item(i).Code.Text = s End If Next ActiveDocument.TrackRevisions = bTrackRevFlag ActiveDocument.ShowRevisions = bShowRevFlag End Sub It bombs on ActiveDocument.Fields.Item(i).Code.Text = s, with an error 5686 ("The operation cannot be completed because the Track Changes option in the master document does not match the option the the subdocument. Make the Track Changes option the same in the master document and subdocument.") However, I'm not entirely sure what that means. Ideas anyone?

• NSNumberFormatter to display custom labels for 10^n (10000 -> 10k)

  - by Michele Colombo

  I need to display numbers on a plot axis. The values could change but I want to avoid too long numbers that will ruin the readability of the graph. My thought was to group every 3 characters and substitute them with K, M and so on (or a custom character). So: 1 - 1, 999 - 999, 1.000 - 1k, 1.200 - 1.2k, 1.280 - 1.2k, 12.800 - 12.8k, 999.999 - 999.9k, 1.000.000 - 1M, ... Note that probably I'll only need to format round numbers (1, 10, 1000, 1500, 2000, 10000, 20000, 30000, 100000, ...). Is that possibile with NSNumberFormatter? I saw that it has a setFormat method but I don't know how much customizable it is. I'm using NSNumberFormatter cause the graph object I use wants it to set label format and I want to avoid changing my data to set the label.

• ListBox Control in VB.NET 2008

  Hi all, I am currently working on a multi branch desktop based project using VB.NET 2008. My Admin want to see the list of currently working branches and not working branches. Additionally they want to know how long a branch is not working. To display the offline branches I first take a ListBox control named lstListBranch and then upon that control I take another ListBox control named lstListTime to display the offline time. I want to permanently hide the scrollbar for lstListTime control and want to scroll lstListTime when lstListBranch is scrolled. Can anyone help me in that purpose? Thanks in advance.

• Why is SVN better than VSS? [closed]

  - by tsilb

  I've heard soooo many people complain about VSS, and noooo people complaining about SVN. We use SVN on my work project. It's slow, regularly freezes up my IDE, and has wonky behavior like looking for a database server every time I right-click the Solution node in my Solution Explorer. When I used VSS, everything worked beautifully, except for access restrictions which I of course blame on the people who control access. VSS is built by Microsoft and thus has great integration with Visual Studio. SVN is written by pretty much anybody with some free time (right?) and thus kinda works most of the time... And I honestly get the impression they had a dozen different directions in the design instead of one. So why do I keep hearing that SVN is better than VSS?
