• Is this the correct way of speaking to a "Content Manager" Class?

  - by DeanMc

  I am creating a silverlight site. I am currently breaking out my ideas into pieces of functionality. One of the idea's I have is the concept of a content manager. This is essentially a UI control with 4 regions. Top, Bottom, Right & Left. I also have a collection of objects that are considered "Menu Items". These are controls that function as a way to navigate around, similar to links. The idea I have is to implement an IMenuItem interface. Among the standard pieces of information (Text, PageReference, etc) I was also going to hold a reference to the content manager. My idea behind this thinking is that I can pass the PageReference to a property on the ContentManager and then call a method which knows how to update the content manager accordingly. Is this the best way of implementing this or is their some sort of pattern for it?

• Having trouble with binding

  - by Tam

  I'm not sure if I'm misunderstanding the binding in Flex. I'm using Cairngorm framework. I have the following component with code like: [Bindable] var _model:LalModelLocator = LalModelLocator.getInstance(); .... <s:DataGroup dataProvider="{_model.friendsSearchResults}" includeIn="find" itemRenderer="com.lal.renderers.SingleFriendDisplayRenderer"> <s:layout> <s:TileLayout orientation="columns" requestedColumnCount="2" /> </s:layout> </s:DataGroup> in the model locator: [Bindable] public var friendsSearchResults:ArrayCollection = new ArrayCollection(); Inside the item renderer there is a button that calls a command and inside the command results there is a line like this: model.friendsSearchResults = friendsSearchResults; Putting break points and stepping through the code I confirmed that this like gets called and the friendsSearchResults gets updated. To my understanding if I update a bindable variable it should automatically re-render the s:DataGroup which has a dataProvider of that variable.

• UITableView section header and section footer not updating (redraw problem)

  - by Gerd

  I have a UITableView grouped style with custom header and footer view. Inside the footer I put a UILabel and a UIButton. Clicking on the button hides or show some rows, updates the UILabel in the footer view and finally resizes footer view. Basically everything is working fine. BUT the text ion the label is not updated on the screen. It is updated in the UILabel text property, but only if I scroll the section footer out of the visible area and scroll it back, it is updated. So it's a typical redraw problem here of the UITableView. I tried every method to force update like needsLayout etc. Nothing helped. I have seen some related questions but with some different behaviour and no solution. Any help/ideas? Thanks, Gerd

• Asking Box2d if a collision happened

  - by Rosarch

  I'm using Box2dx (ported to C#; optimized for XNA). It handles collision resolution, but how can I tell if two objects are currently colliding? This is the function I'm trying to write: public bool IsColliding(GameObjectController collider1, GameObjectController collider2) Where collider1.Model.Body is the Box2d Body, and collider1.Model.BodyDef is the Box2d BodyDef. (The same goes for collider2, of course.) UPDATE: Looks like contact listeners or this could be useful: AABB collisionBox; model.Body.GetFixtureList().GetAABB(out collisionBox); Why does GetFixtureList() return one fixture?

• ASP .NET: SQL Server Money Type and .NET Currency Type

  - by Rudi Ramey

  MS SQL Server's Money Data Type seems to accept a well formatted currency value with no problem (example: $52,334.50) From my research MS SQL Sever just ignores the "$" and "," characters. ASP .NET has a parameter object that has a Type/DbType property and Currency is an available option to set as a value. However, when I set the parameter Type or DbType to currency it will not accept a value like $52,334.50. I receive an error "Input string was not in a correct format." when I try to Update/Insert. If I don't include the "$" or "," characters it seems to work fine. Also, if I don't specify the Type or DbType for the parameter it seems to work fine also. Is this just standard behavior that the parameter object with its Type set to currency will still reject "$" and "," characters in ASP .NET? Here's an example of the parameter declaration (in the .aspx page): <asp:Parameter Name="ImplementCost" DbType="Currency" />

• Why do users have to enter a 7-digit twitter PIN to grant my application access?

  - by Tony

  I am implementing some ruby on rails code tweet stuff for my users. I am creating the proper oauth link...something like http://twitter.com/oauth/authorize?oauth_token=y2RkuftYAEkbEuIF7zKMuzWN30O2XxM8U9j0egtzKv But after my test account grants access to twitter, it pulls up a page saying "You've successfully granted access to . Simply return to and enter the following PIN to complete the process. 1234567" I have no idea where the user should enter this PIN and why they have to do that. I don't think this should be a necessary step. Twitter should be redirecting the user to the callback URL I provided in the application settings. Does anyone know why this is happening? UPDATE I found this article that states I need to send my users to this URL (note "authenticate" instead of "authorize"): http://twitter.com/oauth/authenticate?oauth_token=y2RkuftYAEkbEuIF7zKMuzWN30O2XxM8U9j0egtzKv I made the change but Twitter redirects the user to the authorize path after he clicks "Allow" which then gives him the 7 digit PIN again!

• How to solve/hack fading semi-transparent PNG bug in IE8?

  - by Soul_Master

  As you know, IE6 has bug that can't display semi-transparent PNG file without using non-standard style like filter. In IE7, this problem is fixed. But It still has some bug about PNG file. It can't correctly display fading semi-transparent PNG file. You can clearly see it when you use show/hide function in jQuery with semi-transparent PNG file. The background of image is displayed with non-transparent black color. Do you have any idea for solve this question by using jQuery. Update Let's see my testing As you see, IE8 always incorrectly displays PNG-24 image. Moreover, IE8 still correctly display PNG-8 image when I fade(jQuery.fadeOut function) it only. But It incorrectly display PNG-8 image when I fade & resize(jQuery.hide function) at the same time. PS. You can download my testing source code from here. Thanks,

• Adding rows to UItableview and passing data between Viewcontrollers

  - by Jonathan

  I have a list of websites in a plist, when the app loads this populates a tableview (which is inside a navigation controller) But I have added an add button to the navigation bar and then created another View Controller to deal with inputting of the new website (Like Title and URL). It is very similar to how the contacts app looks. There is a table view and when you tap add, the add UI slides up. I have got all this working great so far. My Problem is what happens when the user taps Done. I can add the website to the plist (each website is a dictionary in the plist with 2 keys, atm) But then how do I tell the tableView to update? The table view has not been removed from the main window, just the add view has been added on top of the "screen". Another way of asking is, when you tap Save on Add a Contact screen: (not my image) How does the new contact's data (Xyz's data) get shown on the tableview?

• How to do regex HTML tag replace in SQL Server?

  - by timmerk

  I have a table in SQL Server 2005 with hundreds of rows with HTML content. Some of the content has HTML like: <span class=heading-2>Directions</span> where "Directions" changes depending on page name. I need to change all the <span class=heading-2> and </span> tags to <h2> and </h2> tags. I wrote this query to do content changes in the past, but it doesn't work for my current problem because of the ending HTML tag: Update ContentManager Set ContentManager.Content = replace(Cast(ContentManager.Content AS NVARCHAR(Max)), 'old text', 'new text') Does anyone know how I could accomplish the span to h2 replacing purely in T-SQL? Everything I found showed I would have to do CLR integration. Thanks!

• What is the C# equivalent of this Excel VBA code for Shapes?

  - by code4life

  This is the VBA code for an Excel template, which I'm trying to convert to C# in a VSTO project I'm working on. By the way, it's a VSTO add-in: Dim addedShapes() As Variant ReDim addedShapes(1) addedShapes(1) = aBracket.Name ReDim Preserve addedShapes(UBound(addedShapes) + 1) addedShapes(UBound(addedShapes)) = "unique2" Set tmpShape = Me.Shapes.Range(addedShapes).Group At this point, I'm stumped by the addedShapes(), not sure what this is all about. Update: Matti mentioned that addedShapes() represents a variant array in VBA. So now I'm wondering what the contents of addedShapes() should be. Would this be the correct way to call the Shapes.Range() call in C#? List<string> addedShapes = new List<string>(); ... Shape tmpShape = worksheet.Shapes.get_Range (addedShapes.Cast<object>().ToArray()).Group(); I'd appreciate anyone who's worked with VBA and C# willing to make a comment on my question & problem!

• Invalid UTF-8 for Postgres, Perl thinks they're ok

  - by gorilla

  I'm running perl 5.10.0 and Postgres 8.4.3, and strings into a database, which is behind a DBIx::Class. These strings should be in UTF-8, and therefore my database is running in UTF-8. Unfortunatly some of these strings are bad, containing malformed UTF-8, so when I run it I'm getting an exception DBI Exception: DBD::Pg::st execute failed: ERROR: invalid byte sequence for encoding "UTF8": 0xb5 I thought that I could simply ignore the invalid ones, and worry about the malformed UTF-8 later, so using this code, it should flag & ignore the bad titles. if(not utf8::valid($title)){ $title="Invalid UTF-8"; } $data->title($title); $data->update(); However perl seems to think that the strings are valid, but it still throws the exceptions. How can I get perl to detect the bad UTF-8?

If not, are there any ways around it? Thank you

• SVN access denied when comparing revisions

  - by Gonzalo

  We're using an SVN repository. I am getting the error below when we try to compare a local unmodified file with the latest revision of the file in the repository. In other words, someone's checked in a change and if I update I will get their change but first I want to see what their change was. DOn't think it matters but we're using Xcode and using the menu item SCM - Compare With - Latest. Error: 220001 (Item is not readable) Description: Unreadable path encountered; access denied Any pointers where to look to fix this appreciated. I looked in the svnserve.conf which has the default settings. Nothing jumped out to me. Also, % svn log returns "svn: Item is not readable". Thanks, Gonzalo

• Transition domain to new web host without waiting for DNS propagation

  - by jcmoney

  I was considering switching to Amazon EC2 to host my website to handle more traffic. It seems like I would have to update DNS records to point to the new server but I was wondering if there was a way to avoid having to wait for the new DNS record to propagate. Putting the code on both hosts would not work for me since the app writes to a database pretty frequently. I thought about just using a meta redirect or php redirect on the old host to redirect to the new host ip but was wondering if there's a better more accepted way of doing this.

• Misunderstanding I have about javascript prototype inheritance

  - by Ilya

  Simple questions. function p() { function A() { this.random = "random"; } A.prototype.newfunc = function(){ alert("5");} function B() { } B.prototype = new A(); var bObj = new B(); } Q1: When I set B's prototype, I don't get how B's prototype property will update when/if A's prototype is updated. I mean, to me it just inherits/copies all those properties. It's not like it's: B.prototype = A.prototype where B and A are one in the same. Q2: After A is being returned and intialized to the prototype object of B, how does JS know not to include that prototype property? What I mean is, we never have this type of situation occuring as the JS interpreter knows just to chop off the property of A's prototype: B.prototype = new A(); //any A object has an associated prototype object B.prototype.prototype;//after initialization we no longer have the separate prototype property of A

• Get svn revision without an appropriate svn binary installed

  - by Sridhar Ratnakumar

  For some reason, we can't update the SVN in some build machines. Installed svn version is 1.3.x. But Hudson slave used 1.6 to create a checkout. This means we can't run "svn info" on those checkouts: $ svnversion subversion/libsvn_wc/questions.c:110: (apr_err=155021) svn: This client is too old to work with working copy '.'; please get a newer Subversion client $ svn info subversion/libsvn_wc/questions.c:110: (apr_err=155021) svn: This client is too old to work with working copy '.'; please get a newer Subversion client $ My question, is there a way to access the revision number without having to invoking the svn binary? You know, like trying to look into the .svn/ directory? Assume that the checkout is using latest svn version (1.6).

• Mutating PDF editable fields programatically

  - by Chris

  Out of tons of questions and answers here about manipulating PDF's with PHP, but none of them seem to fit my requirement. Programmatically, I want to be able to update the content of editable fields. Preferably with PHP. If it matters, the PDF files will be initially hand crafted (as sort of 'template' files that will be copied and filled in over and over again). The list of PDF_* functions on php.net doesn't give me anything that looks (directly) promising. Is this possible with PHP? How?

• TSQL Query: Escaping Special Characters

  - by Abs

  Hello all, I am trying to escape special characters in a TSQL query. I have done this before: SELECT columns FROM table WHERE column LIKE '%\%%' ESCAPE '\' And it has worked. Now I have tried to do this now: UPDATE match SET rule_name='31' ESCAPE '\' But it has failed. I know none of the vlaues have a \ but it should still work. I am guessing its because it needs a LIKE statement but how else can I escape characters that I am adding to a database? In addition, does anyone have a link to all the special characters that should be escaped, I couldn't find any documentation on this! Thanks all for any help

• Android Image Orientation Issue on Motorola Droid

  - by roundhill

  Hi there, Our app uses the gallery pick action to grab an image from the device to upload to a new blog post. We're seeing on the Moto Droid that images taken in portrait are being sent back to the app in landscape orientation so the image is sideways. AFAIK this only occurs on the Droid. Found this via google, but we need the full size image to be uploaded in the correct orientation so the solution doesn't work for us: http://groups.google.com/group/android-developers/browse_frm/thread/1246475fd4c3fdb6?pli=1 An easy way to reproduce this is to take a picture in portrait on the Droid, then send it to yourself via Gmail. In the email message, the image will be in landscape (sideways). I've tested on the droid 2.1 update and the issue is still there.

• ASP.net custom error page

  - by c11ada

  hey all, im trying to implement a custom error page, what i want to be able to do is have a single generic error page which can display the error which occurred or other information (custom error message). when a error occurs on the website, the user should be directed to this page which shows the error message. so for example if i had a page which was trying to update something to a database, but something went wrong, i should be redirected to the error page which will have some custom text like something like " there has been an error with bla bla bla ... please contact administrator". hope this makes sense thanks

• Format of compiled directx9 shader files?

  - by JB

  Is the format of compiled pixel and vertex shader object files as produced by fxc.exe documented anywhere either officially or unofficially? I'd like to be able to read the constant name to register assignments from the shader files. I know that the effects framework in D3DX can do this, but I need to avoid using D3DX as it may not be installed on user's machines and I don't need it for anything else so I want to avoid them having to run the directx update. If the effects framework can do it, then so can I if I can find out the file format but I can' seem to find it documented anywhere.

• TFSBuild.Proj and Manual SQL Server Work Help?

  - by ScSub

  Using the VS 2008 GDR update, I have created a database project. I have created a SQL Server deployment package. I have created a database unit test. Using some wizards, the stuff got into my tfsbuild.proj file so near the end of the automated build process a database is created. I lack a little control of the whole process, I now see. What I would like to do is manually deploy the DB, run 3 custom scripts against the DB, and then manually start the DB unit test. I have other non-DB unit tests that already run. I do not want to use VSMDI or ordered unit test stuff because in out multi-developer environment it gets messy. Help!
