• How to upgrade a 1.4.3 TortoiseSVN created repository to 1.6.x?

  - by SiegeX

  A few years ago we deployed TortoiseSVN 1.4.3 to our software development team and we used this client to create a repository on a share point. We are now looking at upgrading to the latest 1.6.x version of TortoiseSVN. I had hoped this would be transparent as the additional features and modifications will all be client-side. For the most part this is true except for a very important feature -- merging. When I try to merge a feature branch back into truck I get a "Merge tracking not supported error." So now the question becomes, how does one upgrade a 1.4.3 TortoiseSVN created repo to be compatible with the latest 1.6.x version of TortoiseSVN? As a follow up question, if we were to successfully upgrade the repo such that the 1.6.x client works flawlessly, will we still be backwards compatible with a 1.4.x client?

• Are there commercially deployed and used .NET CAS (Code Access Security) based applications?

  - by Dinis Cruz

  I've seen a couple threads here on SO that ask about what CAS is and how to use it.My specific is specifically focused on real-world usages of CAS. For example: DotNetNuke did some efforts in the past to be able to run under Medium Trust: is that still true? what is the % of DNN that run in partial trust (i.e. not full trust)? what & of DNN modules run in partial trust?) Sharepoint defaults to a Partially-Trusted environment on dlls executed from the bin folder: How many 'commercially' available WebParts can run in this bin folder (without changing the policy)? The key here is to be able to point to CAS success stories, so that other companies feel that they should also invest in writing CAS-enabled apps

• Write wave files to memory in Java

  - by Cliff

  I'm trying to figure out why my servlet code creates wave files with improper headers. I use: AudioSystem.write( new AudioInputStream( new ByteArrayInputStream(memoryBytes), new AudioFormat(22000, 16, 1, true,false), memoryBytes.length ), AudioFileFormat.Type.WAVE, servletOutputStream ); taking a byte array from memory containing raw PCM samples and a servlet output stream that gets returned to the client. In the result I get a normal wave file but with zeros in the chunk size fields. Is the API broken? I would think that the size could be filled in using the size passed in the audio input stream. But now, after typing this out I'm thinking its not making this info available to the outer write() method on AudioSystem. It seems like the AudioSystem.write call needs a size parameter unless it is able to pull the size from the stream... which wouldn't work with an arbitrary sized stream. Does anyone know how to make this example work?

• Edit and Create view using EditCreate.ascx partial in ASP.NET MVC

  - by mare

  If you look at the NerdDinner example of creating and editing dinners then you see they use a partial (ViewUserControl or ASCX) DinnerForm to put the functionality of creating and editing dinners into one file because it is essential the same and they use it using RenderPartial("DinnerForm"). This approach seems fine for me but I've run into a problem where you have to add additonal route values or html properties to the Form tag. This picks up the current action and controller automatically: <% using (Html.BeginForm()) { %> However, if I use another BeginForm() overload which allows to pass in enctype or any other attribute I have to do it like this: <% using ("Create", "Section", new { modal = true }, FormMethod.Post, new { enctype = "multipart/form-data" })) and as you can see we lose the ability to automatically detect in which View we are calling RenderPartial("OurCreateEditFormPartial"). We can't have hardcoded values in there because in Edit View this postback will fail or won't postback to the right controller action. What should I do in this case?

• Specification of Extended Properties in OleDb connection string?

  - by Monty

  At the moment I'm searching for properties for a connection string, which can be used to connect to an Excel file in readonly mode. Searching Google gets me a lot of examples of connection strings, but I can't seem to find a specification of all possibilities in the 'Extended Properties' section of the OleDb connection string. At the moment I've this: Provider = Microsoft.Jet.OLEDB.4.0; Data Source = D:\Data\Customers.xls; Extended Properties = 'Excel 8.0; Mode=Read; ReadOnly=true; HDR=Yes'; However... I've composed this by examples. So questions: 1. What is a decent source for OleDb Connection String documentation/reference? 2. Is the above connection string indeed connecting to the Excel file in readonly mode? Thanks!

• Why is the modal dialog in MFC actually internally modeless?

  - by pythiyam

  This question arose in my miind after reading this article: http://www.codeproject.com/Articles/3911/The-singular-non-modality-of-MFC-modal-dialogs. He mentions that the modal dialog in MFC is not strictly modal, but implemented as a modeless dialog(internally) with bells and whistles to make it behave as a modal one. Specifically, he says: The MFC command routing mechanism uses a combination of message maps and virtual functions to achieve what it does and a true modal dialog will totally wreck this mechanism because then the modal message loop is controlled outside the scope of the MFC command routing machinery Could anyone elucidate this statement? An example of what would have gone wrong if they had tried to implement a truly modal dialog would greatly clear things up.

• How to open window pop-up from Silverlight Out-of-Browser?

  - by Jeaffrey Gilbert

  I need to open window pop-up from Silverlight Out-of-Browser application. I've added parameter <param name="enablehtmlaccess" value="true" /> in Index.html, but executing this from code behind: HtmlPage.Window.Navigate(new Uri(myUrl), "_blank", myFeatures); still returns error: Silverlight OOB Error: The DOM/scripting bridge is disabled. I've read about this post, does it mean that I can't open pop-up from OOB? Why I need to do this, because actually I've shown the HTML page in OOB Silverlight by WebBrowser control within ChildWindow but when I click an anchor in HTML page, which linked to _blank page, it jumps to my default browser. It doesn't meet the requirement, except launch that HTML index page also in default browser at the first time, triggered from button control in OOB Silverlight. Is that possible? Please advice, thanks.

• Initializing "new users" in Rails

  - by mathee

  I'm creating a Ruby on Rails application, and I'm trying to create/login/logout users. This is the schema for Users: create_table "users", :force => true do |t| t.string "first_name" t.string "last_name" t.text "reputation" t.integer "questions_asked" t.integer "answers_given" t.string "request" t.datetime "created_at" t.datetime "updated_at" t.string "email_hash" t.string "username" t.string "hashed_password" t.string "salt" end The user's personal information (username, first/last names, email) is populated through a POST. Other things such as questions_asked, reputation, etc. are set by the application, so should be initialized when we create new users. Right now, I'm just setting each of those manually in the create method for UsersController: def create @user = User.new(params[:user]) @user.reputation = 0 @user.questions_asked = 0 @user.answers_given = 0 @user.request = nil ... end Is there a more elegant/efficient way of doing this?

• Smooth mousover images inside scaled Flex App?

  - by Josh Handel

  I have a flex app I am scaling using systemManager.stage.scaleMode=StageScaleMode.NO_BORDER; for the most part it works well except for my bitmap data (mostly png's from the designers). I can set the mx:image tags to smoothBitmapContent=true and that works great for everything except my mouseover objects. When I do a mouseover, the source is being changed from one embedded image to another embedded image. I have tried several (many) online "smoothimage" classes, and tried to write my own, I have tried to reset smoothBitmapContent every chance I get but still no dice. It seems to mee that because I am scaling at the app level, that the flopped out bitmap is not getting smoothed when it renders. Does anyone have any suggestions on how to keep things smooth (perhaps there is a flag to tell Flex to smooth stuff when it scales it?). Thanks Josh

• WPF ListView.CurrentChanged too fast for binding

  - by matt

  My case: MVVM ListView+Details(custom UserControl) List bound to MV.Items (IsSynchronizedWithCurrent=true) Details bound to MV.Items.Current MV.Items.Count == 100 about 0.2sec to read details (lazy mode) When I hold the down arrow on the list, very strange things happen: list items order change current changes in the random order CPU usage drastically increments and eventually all hangs. I've read some post that one should start the timer or run handler in the background, but I am not able to do that, since all the binding WPF does for me. Is there some way to instruct the binding in my DetailsControl, to wait a while before accepting CurrentItem? Or should I just resign from the clean solution and write custom code in my MV to handle that?

• Dealing with ArrayLists in java...all members of the arraylist updating themselves?

  - by Charlie

  I have a function that shrinks the size of a "Food bank" (represented by a rectangle in my GUI) once some of the food has been taken. I have the following function check for this: public boolean tryToPickUpFood(Ant a) { int xCoord = a.getLocation().x; int yCoord = a.getLocation().y; for (int i = 0; i < foodPiles.size(); i++) { if (foodPiles.get(i).containsPoint(xCoord, yCoord)) { foodPiles.get(i).decreaseFood(); return true; } } return false; } Where decreaseFood shrinks the rectangle.. public void decreaseFood() { foodAmount -= 1; shrinkPile(); } private void shrinkPile() { WIDTH -=1; HEIGHT = WIDTH; } However, whenever one rectangle shrinks, ALL of the rectangles shrink. Why would this be?

• How to run report in ReportViewer without having to click View Report button?

  - by user259286

  I've set up my report with params and it's value. When I run the page, it wants me to click the View Report button, but I need it to just run instead of interacting. Any ideas on this? Here's my code: rptViewer.Reset(); rptViewer.ProcessingMode = ProcessingMode.Remote; rptViewer.ServerReport.ReportServerUrl = new Uri("http://rptserver/reportserver"); rptViewer.ServerReport.ReportPath = "/Reports/My Report"; ReportParameterInfoCollection param = rptViewer.ServerReport.GetParameters(); ReportParameter[] rps = new ReportParameter[] {new ReportParameter(param[0].Name, param[0].ValidValues[0].Value)}; rptViewer.ServerReport.SetParameters(rps); IReportServerCredentials netCred = new CustomReportCredentials("me", "pwd", "domain"); rptViewer.ServerReport.ReportServerCredentials = netCred; rptViewer.ServerReport.Refresh(); rptViewer.SizeToReportContent = true; Thanks!

• ASP.net VB Timers

  I would like to be able to time a page load time in ASP.net (VBscript). Adding Trace="true" to the page directive is nice, but I need to actually time an event and store it in a variable. In ASP it was easy with the Timer object, but in .net I can't find anything on Google. I need something along the lines of: Dim startTime Dim endTime startTime = now() doBigFunction() endTime = now() response.write("That took " & endTime - startTime & " milliseconds") Cheers!

• how to ingore comma when returning json mvc

  - by Darcy

  Hi all, I'm returning JSON from my controller to my view in order to populate a jquery autocomplete textbox in MVC. The problem is, some of my data contains commas, and therefore is split by the autocomplete helper. Heres my code. Controller: public ActionResult GetData() { var data = repository.GetData(); return Json(data); } View (script): $.post("../MyController/GetData", function(data) { var evalData = eval(data) + ""; //formats the text $("#Data").autocomplete(evalData.split(","), { max: 500, matchContains: true }); }); As you can see, I am using the jquery .split helper to split the returned Json. Should I be using regex or should I go with a completely different approach?

• How to get login password in servlets

  I've successfully implemented form based authentication, and now I want to get the username and password to initialize session object in javamail from servlets. How can I do that? I can getlogin username by using method request.getRemoteUser(), but I don't know how to get the password.

• Rails AR validates_uniqueness_of against polymorphic relationship

  - by aaronrussell

  Is it posible to validate the uniqueness of a child model's attribute scoped against a polymorphic relationship? For example I have a model called field that belongs to fieldable: class Field < ActiveRecord::Base belongs_to :fieldable, :polymorphic => :true validates_uniqueness_of :name, :scope => :fieldable_id end I have several other models (Pages, Items) which have many Fields. So what I want is to validate the uniqueness of the field name against the parent model, but the problem is that occasionally a Page and an Item share the same ID number, causing the validations to fail when they shouldn't. Am I just doing this wrong or is there a better way to do this?
