• WPF Animate a Matrix using interpolation

  - by Mark

  I'm having a issue with my application that is using touch gestures to scale, translate and rotate my scene. I was using a TransformGroup which contained TranslateTransform, ScaleTransform and a RotateTransform but I could not get the movement correct, it always jumps and skips, so I moved to a MaxtrixTransform which I was able to use much easier to get my scene to be zoomable, rotatable and panable nicely. However, what I later found out was that you cannot animate smoothly (using interpolation) the values of a Matrix, for what reason I have no idea, but its part of the MSDN doco and the properties of the Matrix are not dependency properties anyways... Has anyone had any luck animating a matrix to make it smooth? The only idea(s) I have had is to animate a few different, custom DP which all have callbacks that I update the matrix from OR To convert the matrix to a set of Transform objects that I then animate and then afterwords convert back. Is there a smarter way to do this?

• Determine Click-thru Percentage With PHP

  - by Lea

  Hi all, I am currently working on a small sponsorship application(PHP/MySql) for my personal blog, and am almost finish, but I am stuck on how to calculate the click-thru rate of my sponsors campaigns. I was always terrible with working out percentages, so any practical help would be appreciated. The data is stored in the DB as simple numbers.. So as expected, when a page refreshes, or a sponsors ad is clicked, the data updates with an incrementation of 1. So using these values...say $clicks and $impressions, how would I determine the click-thru rate? What would be the sum I would use to calculate? An example function would really be appreciated. Kind Regards, Lea

• popToRootViewControllerAnimated and dealloc all views

  - by mongeta

  Hello again, I have a UINavigationController that asks for some information and the user navigates until the end, once there, they can Accept or Cancel all the data that has been entered. It doesn't matter wich option they choose, as they always will go to the first view using [UINavigationController popToRootViewControllerAnimated:] The question is, how I can release/deallocate all the views ? For example, they start for view 1 and the end is at view 8, once they go directly to the 1 from the 8, how I can release view 2,3,4,5,6,7,8 ? thanks, regards, m.

• How to control Time zone formatting in System.Xml.Serialization or during application execution?

  - by Beal

  I'm developing a C# .Net Application that is executing on a system located in the Central Time Zone. The application gets information from a third party using an API they provide. I have used the WSDL to produce the code that my application access the API with...their reporting API allows you to define a start date and end date for the report. These are C# DateTime fields and XSD:dateTime. Now when I set the start date and end dates and allow the API to create the SOAP messages the dates don't always include a Time Zone unless I set the date fields using the ToLocalTime method; however, the method will create the DateTime fields in the Central Time Zone (CST) but I need to have it create these fields in the Pacific Time Zone (PST). If I set my machine time to PST all is good...but of course that causes other time issues. What methods can I use to control the formatting of the DateTime? Alternatively, is there a application setting that can be set in C# that allows timezone control?

• Retrieving Gtk::Widget's relative position: get_allocation() doesn't work

  - by a-v

  I need to retrieve the position of a Gtk::Widget relative to its parent, a Gtk::Table. Most sources (e.g. http://library.gnome.org/devel/gtk-faq/stable/x642.html) say that one needs to call Gtk::Widget::get_allocation(). However, the returned Gtk::Allocation object always contains x = -1, y = -1, width = 1, height = 1. I have to note that this happens before the Gtk::Table object is actually exposed and rendered. A call to show_all_children() or check_resize(), which I would expect to recalculate child widget geometry, doesn't help. What am I doing wrong? Thanks in advance.

• How to secure authorization of methods

  - by Kurresmack

  I am building a web site in C# using MVC.Net How can I secure that no unauthorized persons can access my methods? What I mean is that I want to make sure that only admins can create articles on my page. If I put this logic in the method actually adding this to the database, wouldn't I have business logic in my data layer? Is it a good practise to have a seperate security layer that is always in between of the data layer and the business layer to make? The problem is that if I protect at a higher level I will have to have checks on many places and it is more likely that I miss one place and users can bypass security. Thanks!

• Java is open-source, so what?

  - by typoknig

  Hi all, I always here that Java being open-source is a big benefit, but I fail to see how Java being open-source should draw me to use it as opposed to .NET which is closed-source. This website has some Q&A sections (What is the significance of these developments to the industry? in particular) that give a little info, but is being free the only (or the biggest) advantage to Java being open-source? Since I am a beginner, have any of you pros noticed any major difference since the change was made?

• Convert any currency string to double

  - by James

  I need to store multiple currencies in SQL server. I understand that SQL won't support all different types of currencies (unless I store it as a string, but I don't want to do that). My idea was to convert all the values from their currency format to a standard double and store that instead. Then just re-format based on the culture info when displaying. However, I have tried doing something like e.g. var cultureInfo = new System.Globalization.CultureInfo("en-US"); double plain = return Double.Parse("$20,000.00", cultureInfo); This doesn't ever seem to work it always throws a FormatException. Even removing the currency symbol and just trying to do this based on the number alone does the same thing. This is just an example I want to support pretty much any type of currency. Is there a standard way of stripping out currency and getting the value as a double?

• Getting ssh to execute a command in the background on target machine

  - by dagorym

  This is a follow-on question to the How do you use ssh in a shell script? question. If I want to execute a command on the remote machine that runs in the background on that machine, how do I get the ssh command to return? When I try to just include the ampersand (&) at the end of the command it just hangs. The exact form of the command looks like this: ssh user@target "cd /some/directory; program-to-execute &" Any ideas? One thing to note is that logins to the the target machine always produce a text banner and I have ssh keys set up so no password is required.

• Why use SyncLocks in .NET for simple operations when Interlocked class is available?

  - by rwmnau

  I've been doing simple multi-threading in VB.NET for a while, and have just gotten into my first large multi-threaded project. I've always done everything using the Synclock statement because I didn't think there was a better way. I just learned about the Interlocked Class - it makes it look as though all this: Private SomeInt as Integer Private SomeInt_LockObject as New Object Public Sub IntrementSomeInt Synclock SomeInt_LockObject SomeInt += 1 End Synclock End Sub Can be replaced with a single statement: Interlocked.Increment(SomeInt) This handles all the locking internally and modifies the number. This would be much simpler than writing my own locks for simple operations (longer-running or more complicated operations obviously still need their own locking). Is there a reason why I'd rolling my own locking, using dedicated locking objects, when I can accomplish the same thing using the Interlocked methods?

• Using memtables in sql. When is it reasonable and is it safe?

  - by Spiros

  I was just reading an update from a friend's project, mentioning the use of memtables to store data temporatily and then flush to a table on disk. Up to now, I have never faced a situation where I would use a memtable, or a situation where I would think the use of a mem table would be beneficial; so I wonder, when would someone use mem tables? what makes a memtable (appart from access speed) a reasonable choice? and how safe is it, even for temp data? there is always the limitation of available physical memory.

• Respecting EXIF orientation when displaying iPhone photos on the web

  - by GingerBreadMane

  I am developing an iPhone camera app that uploads an image to Amazon S3 and that image is displayed on a website. When the iPhone takes a picture, it always saves the photo in an upright orientation, while the orientation used to correctly view the photo is saved in the image's EXIF data. So if I take a photo with the iPhone and open it in FireFox without processing the EXIF data, the image could be sideways or upside down. My problem is that I don't know how to display the photo in it's correct orientation on the website. My current solution is to rotate the photo in the iPhone app, but I'd rather not do that. Is there anyway to respect the EXIF data when displaying on the web without pre-processing the image?

• Does ImageIO read imply anti-aliased scaling?

  - by tigger

  I've replaced the Java internal ImageFetcher with an own implementation using ImageIO. Some image renderers of our software, which use these images, now draw anti-aliased scaled images instead of non anti-aliased. The only change is the source of the image, which are now BufferedImages instead of Toolkit-Images. The question now is, where is the difference? Which property causes the images to scale anti-aliased? I've always thought that the anti-alias key ONLY depends on the graphics I paint on - but this is obviously wrong. By the way: unfortunately I cannot change the renderers.

• List service and services status under Win-7

  - by Ronaldo Junior

  I have a service monitor app that monitors the status of three other servers app - you know those kind of green, red status stuff, start, stop, etc. The problem is that it shows the wrong state in Windows 7 even if the user is the administrator. The start, stop buttons are disabled and the install button enabled, the status color is grey which is also wrong. The start button should be enabled with the service status showing green - the apps are running. If the application is run with the setting "run as administrator" then it behaves normally. The application is written in Delphi 7 and works perfectly in other versions of Windows. This line of code: OpenSCManager(PChar(sMachine),Nil,SC_MANAGER_ALL_ACCESS) always return 0 under Win7, causing the problem. Any ideas and if possible, any workaround apart from "run as administrator". Regards Ronaldo

• How to debug a corrupt pdf file?

  - by Joelio

  Hi, im generating pdf files using a ruby library called "prawn". I have one particular file that seems to be considered "Corrupt" by adobe reader. It shows up fine in both preview and in adobe reader. It gives errors like: Sometimes I get: "Could not find the XObject named '%s'. Othertimes I get: "Could not find the XObject named "Im4". Then always I get: "An error exists on this page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem." Is there a way to open a pdf with some tool and have it tell you what is technically wrong with the pdf? Im sure I could figure it out quickly with something like this... thanks Joel

• How do I put my return data from an asmx into JSON? I'm having trouble finding decent literature

  - by jphenow

  I want to return an array of javascript objects from my asp.net asmx file. ie. variable = [ { *value1*: 'value1', *value2*: 'value2', ..., }, { . . } ]; I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable. Thanks in advance for assistance.

• implicit parameter definition in class

  - by coubeatczech

  implicit val odkaz = head; def vypis(implicit odkaz:Prvek):String = { odkaz match{ case null => "" case e => e.cislo + " " + e.pocet + "\n" + vypis(e.dalsi) } } ... def main(args:Array[String]){ val q = new MyQueue() // insert some values println(q.vypis) } This method(vypis) is a member of an queue-class so I'll always want to implicity start the recursion from the start of the queue, when calling the method from outside. Is there a way how to write it, that the method from outside calling, there's no paramter, but in inside, there's a parameter - for recursion...? The compiler complains that the parameter is not defined when called from outside

• How to OCR a specific region of a MODI.Document?

  - by Mark Kadlec

  I need to OCR a specific region of a scanned document and I am using MODI (Microsoft's Document Imaging COM object). My code currently OCR's the entire page (quite accurately!), but I would like to target a specific region of the page where the text is always static (order number). How can I do this? Here is my code for the page: MODI.Document md = new MODI.Document(); md.Create("c:\\temp\\mpk.tiff"); md.OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true, true); MODI.Image image = (MODI.Image)md.Images[0]; FileStream createFile = new FileStream("c:\\temp\\mpk.txt", FileMode.CreateNew); StreamWriter writeFile = new StreamWriter(createFile); writeFile.Write(image.Layout.Text); writeFile.Close(); md.Close(); Can I somehow specify the region of the image? Any help would be greatly appreciated!

• GAE/J: unable to register a custom ELResolver

  - by dfa

  I need to register a custom ELResolver for a Google App Engine project. Since it must be registered before any request is received, as specified by the Javadoc: It is illegal to register an ELResolver after the application has received any request from the client. If an attempt is made to register an ELResolver after that time, an IllegalStateException is thrown. I'm using a ServletContextListener: public class RegisterCustomELResolver implements ServletContextListener { @Override public void contextInitialized(ServletContextEvent sce) { ServletContext context = sce.getServletContext(); JspApplicationContext jspContext = JspFactory.getDefaultFactory().getJspApplicationContext(context); jspContext.addELResolver(new MyELResolver()); } ... } The problem is that JspFactory.getDefaultFactory() returns always null. I've alreay filled a bug report. Any idea for a workaround?

• Why would a UIDatePicker with no functionality, added to my app via IB, cause my app to crash?

  - by BeachRunnerJoe

  I just added a UIDatePicker to my iPad app using IB, linked it to its outlet in the code, saved it in IB, added the UIPickerViewDelegate to my UIViewController in the code, as well as added the UIDatePicker outlet in code. When I build and run, the app launches, but will crash intermittently when I attempt to open the popover view that contains the datepicker. I say intermittently because the popover view will occasionally open successfully, but never more than once (it always crashes the second time you open the popover, if it doesn't crash the first time). Also, in the console, I get the following messsage objc[594]: FREED(id): message lastClickRow sent to freed object=0x6015a70 Why is this happening and how can I fix it? What does that console message indicate? It may be worth mentioning that the popover view also contains a table view along with the datepicker control. Thanks so much in advance for your help!

• How to rebase onto a private branch with conflicts in gerrit/git?

  - by edwardmlyte

  Aim: I want to rebase commit G from "bravo", onto commit F from "alpha". From this: G bravo / D--E--F alpha / A--B--C mainline To this: G bravo / D--E--F alpha / A--B--C mainline "alpha" has been successfully rebased onto the latest mainline work. I cherry-pick "alpha" onto C. And when I cherry-pick "bravo", it comes up with all the merge conflicts. Once I fix those, if I do commit --amend The commit message just has all the information for alpha, whereas I'd expect the information for bravo. So I tried again after hard resetting to C, doing pull (as oppose to cherry-pick) for alpha and then pull bravo. Fixed the conflicts and just ran: commit The commit message just lists it as a merge and has merge information. Though the commit succeeds, I can't push this to gerrit as it says I don't have the rights to push merges. When I've read about rebase, it's always just to mainline, but I want to rebase private branches. Where am I going wrong?

• Getting a Target to run BEFORE anything else runs when building from Visual Studio

  - by damageboy

  Hi, I'm trying to get a one-time costly target to run only when building a certain top-level project (that has many dependencies). I have no problem on getting this working from plain msbuild / command line build. I do this with setting and InitialTargets on the project, or alternatively with < BeforeBuild /. The tricky part is with Visual Studio. When I build the same project from VS. VS runs the dependencies before even invoking my .csproj, so my target (which affects how the other projects are built) doesn't get to run until they have already been built. Is there someway to force VS to run a target before invoking the dependencies? I'm currently working around this, by running the same costly target from my most low-level project (the one that get's always built...) by using: Condition=" $(BuildingInsideVisualStudio) " Any ideas on how to get this done "properly"? Again, I'm looking for a solution that will work FROM VS.
