• Is there a built-in way to determine the size of a WCF response?

  - by jaminto

  Before a client gets the full payload of the web request, we'd like to first send it a measurement of the size of the response it will get. If the response will be too large, the client will present a message to the user giving them the option to abort the operation. We can write some custom code to preload the response on the server, determine the size, and then pass it on to the client, but we'd rather not if there's another way to do it. Does anyone know if WCF has any tricky way to do this? Or are there any free third party tools out there that will accomplish this? Thanks.

• Replacement for Azure SDK Powershell commandlets for deployments

  - by Frank Rosario

  Hi, We've run into an issue with the New-Deployment Azure Powershell commandlet timing out; we've put in a bug report with MS. While they gave us an explanation for it (the path and timeout threshold used to upload through commandlets is different then what's used by the web portal); they don't have a fix for us. We need to get this running so we can automate our build deployments, so we're looking into developing a custom commandlet to replace New-Deployment using the Azure SDK; hoping this path will not have the timeout issues the commandlet did. But before we go down that route; are there any other scriptable tools I can use to replace the New-Deployment functionality? I looked at Cloudberry for Windows Azure; but that doesn't have a scriptable interface yet. Any constructive input is greatly appreciated.

• Why does addSubview load the view asynchronously

  - by moshe

  I have a UIView that I want to load when the user clicks a button. There happens to be some data processing that happens as well after I call addSubview that involves parsing an XML file retrieved from the web. The problem is the view doesn't show up until after the data processing even if addSuview is called first. I think I'm missing something here, can anyone help? Code: I have a "Loading..." view I'm adding as a custom modal (meaning I'm not using the modalViewController). This action is linked to a button in the navigationController. - (IBAction)parseXml:(id)sender { LoadingModalViewController *loadingModal = [[LoadingModalViewController alloc] initWithNibName:@"LoadingModalViewController" bundle:nil]; [navigationController.view addSubview:loadingModal.view]; [xmlParser parse]; }

• SharePoint Cannot Log in after making entry in hosts file

  - by bmw0128

  I'm building a MOSS 2007 site on Windows 2008 R2, 64 bit. Not wanting to use my machine name or IP in the URL, I made an entry in my hosts file: 127.0.0.1 mydev.com I can surf to the URL, http://mydev.com, but when I try to log in (Windows Authentication), I am denied. I am able to successfully log in if I take out the hosts file entry, and surf to http:// Do I need to edit something else for the authentication to work when I want to use a custom URL like mydev.com that is only mapped in the hosts file?

• Configuring IoC container from modules/plug-ins ?

  - by rouen

  Hi guys, i am in big dilema.. I am working on highly modular web app in ASP.NET MVC 2 (in fact, core will be super lightweight, all work on modules/plugins). I found MEF pretty useful for modules discovery, but i dont want to us it as IoC container. There is pretty good chance that I will need advanced features of "true" IoC container, so I would like to use Unity. And here is the problem : how to allow modules to configure container (programatically) = register their own types (mvc controllers, custom implementations of services...) at application start without making hard dependency on Unity in all modules ? I know about Common Service Locator project, and it seems pretty good, but this interface co container only allows resolving types, not registering them (afaik). I really hope you can understand my point, I know my english is terrible (I am from non english speaking country :) Thanks a lot !

• MySQL indexes: how do they work?

  - by bob-the-destroyer

  I'm a complete newbie with MySQL indexes. I have several MyISAM tables on MySQL 5.0x having utf8 charsets and collations with 100k+ records each. The primary keys are generally integer. Many columns on each table may have duplicate values. I need to quickly count, sum, average, or otherwise perform custom calculations on any number of fields in each table or joined on any number of others. I found this page giving an overview of MySQL index usage: http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html, but I'm still not sure I'm using indexes right. Just when I think I've made the perfect index out of a collection of fields I want to calculate against, I get the "index must be under 1000 bytes" error. Can anyone explain how to most efficiently create and use indexes to speed up queries? Caveat: upgrading Mysql is not possible in this case. Using Navicat Light for db administration, but this app isn't required.

• iPhone filesystem POSIX-compliant?

  - by Seva Alekseyev

  Hi all, I'm trying to pass some files from one app to another. I communicate the path (via a custom URL). The target application cannot read the file, citing errno 13 (permission denied). I've checked the permissions on file - they're 0644 (O+R), the permissions on directories all the way up to the root are 755 (O+RX). From a POSIX perspective, the file should be readable to any process and any user. Yet it's not. Any ideas, please? I can think of some workarounds. I could use a Web service (upload, get a cookie, communicate the cookie to the other app, other app downloads). I could also pass the actual file data in the URL - unelegant, and probably subject to length limitations. Clipboard is not supported on iPhone OS 2 IIRC.

• How to highlight matching sub-strings inside a ListBox?

  - by Kishore Kumar

  I have one TextBox and one listbox for searching a collection of data. While searching a text inside a Listbox if that matching string is found anywhere in the list it should show in Green color with Bold. eg. I have string collection like "Dependency Property, Custom Property, Normal Property". If I type in the Search Text box "prop" all the Three with "prop" (only the word Prop) should be in Bold and its color should be in green. Any idea how it can be done?. Data inside listbox is represented using DataTemplate.

• How to make distributed builds using XCode 3.2 on OS X 10.6

  - by Sorin Sbarnea

  After I upgraded using a clean install from OS X 10.5 to 10.6.2 and upgraded the XCode to 3.2.1 I wasn't able to use distributed builds feature anymore. There are several issues that I detected: In most cases Bonjour is not detecting the other computers even they are on the same switch. I added a custom 'set' where I added manually the IP addreses of each computer. Even so I still get status: "unreachable" on them.BTW, ping does work without problems. Both share my computer for shared workgroup builds (distcc) and distribute builds via shared workgroup builds options are checked.

• How to add a php page to Wordpress

  - by rutherford

  I want to create a custom page for my Wordpress blog that will execute my php code in it, whilst remaining a part of the overall site css/theme/design. The php code will make use of 3rd party APIs (so I need to include other php files) How do I accomplish this? N.B. I do not have a specific need to interact with the Wordpress API - apart from including certain other php libs I need I have no other dependencies in the PHP code I want to include in a WP page. So obviously any solution that didn't require learning the WP api would be the best one.

• Building a Monopoly Board with GridBagLayout

  - by Oetzi

  I have been building a Java version of Monopoly in my spare time and am having some trouble understanding layouts etc for Swing. Each one of my spaces on the board is a essentially a custom JButton and I have been trying to lay them around the edge of a frame (like on the monopoly board itself). I can't seem to find a useful explanation of how the layout system works and so am having trouble do so. Could someone please give me an example of how they would lay the buttons around the edge of the frame? Should I be using a different layout?

• Zend_Session: unserialize session data

  - by takeshin

  I'm using session SaveHandler to persist session data in the database. Sample session_data column from the database: Messenger|a:1:{s:13:"page_messages";a:0:{}}userSession|a:1:{s:7:"referer";s:32:"http://cms.dev/user/profile/view";}Zend_Auth|a:1:{s:7:"storage";O:19:"User_Model_Identity":3:{s:2:"id";s:1:"1";s:8:"username";s:13:"administrator";s:4:"slug";s:13:"administrator";}} I want to delete Zend_Auth object from this session data. How can I unserialize those objects and remove object I need? I suspect, that I don't have to write my custom parser, that Zend_Session already has a method to do this. I have tried different combinations of unserialize but it still returns false. I'm using autoloader from ZF 1.10.2 and Doctrine 1.2

• msbuild for .NET 3.5 issue with csla and System.Linq

  - by Sash

  This is a weird problem. I am trying to build a .NET 3.5 solution with msbuild. I generally write custom build scripts for this, and when I tried this time to build a simple .NET assembly which internally uses CSLA, it started giving me Linq errors. However, if I build the proj file via msbuild (command line), it seems to build just fine. No issues at all. Anyone else encounter this issue...and if yes, how do i fix this? Thanks, Sashidhar Kokku

• jQuery jPicker path issues when used in WordPress Theme Options

  - by Scott B

  Anyone with experience using jPicker colorpicker in a WordPress Custom Theme options panel. I believe that the default path for the jPicker resources is /jPicker/ relative to the location the js file appears, however, I'm not seeing the picker.gif icon, so I tried changing the path in the js file like so... images:{clientPath:"../wp-content/themes/myTheme/images/" Everything else appears to be working at first load. My bound input field's background color is the same as the currently selected color. However, the picker.gif icon is missing. Where it should appear, I've just got a 2px wide by 20px tall color element (looks like a div perhaps).

• WordPress: don't show 404 when no posts exist

  - by philfreo

  Currently there is a bug in WordPress if you have a Posts Page set under: Settings-Reading-A Static Page-Posts Page If there are posts, than the page (e.g. with a slug called news) displays the post, and uses index.php from the theme. But, with this configuration, if there are no posts, then it calls the theme's 404 page. This is definitely a bug, and has been submitted (Ticket #10822). It should be letting index.php show whatever it wants upon !have_posts(), but right now the page doesn't seem to be called at all. My question is: is there a workaround for this bug without modifying core wp files? I'd be open to a plugin, theme changes, a custom page template, htaccess changes, etc.

• Per query relevance elevation for solr?

  - by plusplus

  I want to tune the relevance of solr search results on a per user basis - based on the number of times the user has clicked through a result before. Frequently hit items FOR THAT USER should rise to the top of their search results. Is there a way to provide custom boost/elevation for particular document ids on the query? I'm thinking in the order of ~100s of particular documents to elevate. The elevation should have no effect if the rest of the query doesn't find those documents. Alternatively, if this isn't possible, what is a sane way for setting up an alternative indexing approach that would make this possible? Could I add a field per user in the index to store their scores? I'm thinking in the order of 1000 users. The major drawback of that approach is the number of times a document would need to be reindexed (i.e. each time it was used by the user).

• Multithread Communication

  - by Robert

  I'm creating a WPF application that uses a custom object to populate all the controls. The constructor of that object is initiated by an EventHandler that waits for an API. The problem I'm having is when I try to access any information from that object using a button for example, it returns an error saying "The calling thread cannot access this object because a different thread owns it". I'm assuming this is because the EventHandler creates a new thread which doesn't allow the MainThread to have access to it. Any ideas on how to get around this?

• Umbrella websites with Microsites & Blogs - recommendations

  - by pingu

  Hi guys, I'm in the process of scoping a solution for an events organisation. Their main website features information about them and blog entries etc, but they hold major events which require microsites (domain.com/event). The microsites all have a different look-and-feel, different nav structure, and custom content-managed components. The one thing that's common across everything is the blog - it will have a category for each event under which users can post. How would you guys implement this? The solution needs to be PHP, and my initial thought was CodeIgniter but if possible I'd like to avoid building the blog functionality - so I guess I could integrate it with EE or Wordpress. If anyone has any other suggestions they would be most appreciated.

• Windows Phone Mango: Making a drawing app with various brushes option

  - by Md. Abdul Munim

  I am trying to make a drawing app. The purpose is simple. Let the user draw something on a canvas with various brush options like square brush,far brush,pencil brush and many more like any other drawing app available in android market. At present I can let the user draw smooth curves using following code: currentPoint = e.GetPosition(this.canvas); Line line = new Line() { X1 = currentPoint.X, Y1 = currentPoint.Y, X2 = oldPoint.X, Y2 = oldPoint.Y }; line.Stroke = new SolidColorBrush(Colors.Purple); line.StrokeThickness = 2; this.drawnImage.Add(line); this.canvas.Children.Add(line); oldPoint = currentPoint; Now I want some custom brush options and let the user draw using that.How can I achieve that? Thanks in advance.

• Qt - invalid conversion to child class

  - by David Davidson

  I'm drawing polygons using the Graphics View framework. I added a polygon to the scene with this: QGraphicsPolygonItem *poly = scene->addPolygon(QPolygonF(vector_of_QPointF)); poly->setPos(some_point); But I need to implement some custom behaviour like selection, mouse over indicator, and other similar stuff on the graphics item. So I declared a class that inherits QGraphicsPolygonItem: #include <QGraphicsPolygonItem> class GridHex : public QGraphicsPolygonItem { public: GridHex(QGraphicsItem* parent = 0); }; GridHex::GridHex(QGraphicsItem* parent) : QGraphicsPolygonItem(parent) { } Not doing much with that class so far, as you can see. But shouldn't replacing QGraphicsPolygonItem with my GridHex class? This is throwing a " invalid conversion from 'QGraphicsPolygonItem*' to 'GridHex*' " error: GridHex* poly = scene->addPolygon(QPolygonF(vector_of_QPointF)); What am I doing wrong?

• Thoughts on try-catch blocks

  - by John Boker

  What are your thoughts on code that looks like this: public void doSomething() { try { // actual code goes here } catch (Exception ex) { throw; } } The problem I see is the actual error is not handled, just throwing the exception in a different place. I find it more difficult to debug because i don't get a line number where the actual problem is. So my question is why would this be good? ---- EDIT ---- From the answers it looks like most people are saying it's pointless to do this with no custom or specific exceptions being caught. That's what i wanted comments on, when no specific exception is being caught. I can see the point of actually doing something with a caught exception, just not the way this code is.

• How do I fix a font compatibilty issue from Mac to Windows, using Adobe Flash CS4?

  - by Michel Carroll

  Hi, I need to edit a Flash movie that somebody else developed in Adobe Flash CS3 on a Mac. I'm using Adobe Flash CS4 on Windows (Vista). However, the font that shows up on my computer is much bigger than on the .SWF that he produced. He used a custom font, which I had to add to my system Fonts folder. Because Adobe Flash detected the right fonts on my computer, it didn't map them to substitute fonts. I verified that Flash is indeed using the same font files that he used. I believe the fonts are being rendered differently because I'm using Windows. How do I fix this?
