• IIS7.5 is only resolving to the Default Web Site

  - by Dennis Burnham

  I am able to access only the Default Web Site on a Windows 2008 R2 Server which is running IIS 7.5 The Default Web Site's binding is to "All Unassigned", same way as I have done it on a different machine running IIS6 under Windows 2003 Server. The bindings of the desired Web Site have the IP address of the server and the correct home directory. Regardless what I do, the only page content I can see is the default index page in the wwwroot directory which is the Default Web Site. What must I do to deliver the correct content from the Web Sites that are configured in IIS7.5?

• How to step down voltage from 208V to 110V

  - by Eric Dennis

  I have some racks that will be fed by 208V/20A circuits. These circuits will be conditioned and battery-backed by the facility in which these racks will live. 99% of the devices in the rack will be able to support 208V input, so I plan to use these PDUs. However, there may be one or two odd devices that will need 110V input. I know that I can use a step-down transformer to provide 110V for these devices, but that seems like overkill for such a small number of devices, plus I don't want to pay extra for the UPS functionality since my power will already be battery-backed. Any suggestions for something I can use for these one-off 110V devices?

• Ubuntu 11.04 fresh install - "Input signal out of range" or "Mode not supported..."

  - by Dennis

  I recently installed Ubuntu 11.04 using a CD .iso. Installation went fine. Upon completion I rebooted and after a second or two I got a black screen with the message "Input signal out of range". And there it sits... Read a few things about how this could be related to screen resolution, refresh rate, etc. For the heck of it I tried a different monitor. The result is the same but the message provides some clues - "Mode not supported - H:92.7kHz, V:58.3Hz" (the latter is Hz; not kHz). So my thought is that I should probably be able to use the 11.04 install disc to "Try out Ubuntu", find and edit some file that was created by the install with the correct values. Problem is, I am not too sure what I am supposed to edit. Looked at the xorg.conf file but this is so minimal at this point I am not sure it is where I want to go. By the way, the monitor is an I-Inc ix191a. Anyone have any ideas on how to get around this?

• How can I make my laptop use a phone as a wi-fi adapter?

  - by Dennis Williamson

  I have an HP Pavilion dv6400 series laptop with an NVidea chipset which is the subject of a class action lawsuit. The symptom (PDF) that I'm experiencing is that the system fails to recognize that there is a wireless adapter installed. It doesn't appear in Device Manager. In this question, I ask if there's a way to work around this problem. As an alternative, I'd like to see if there's a way to use an old Windows Mobile 5 phone that does not have cellular service (voice or data) as a Wi-Fi adapter. How can this be accomplished? The system is running Windows Vista Home and has the latest BIOS (F42) and Windows updates and drivers.

• Not getting my normal internet speed but my other computers can?

  - by Dennis

  I have Comcast Xfinity and I cannot reach anywhere near my promised speed. My family desktop which is hardwired into the router reaches to 60Mbps and so do my parents computers and my brothers. I cannot seem to get anywhere close to it, I know with being wireless I won't reach it, but I should at least get somewhere close. I can only pull 6Mbps and thats terrible for what I should be receiving. Any clue what could be wrong here? Edit: I have 100% signal and I'm not behind any walls

• How to set up an extended desktop on dual monitors in Kubuntu 9.04?

  - by Dennis

  I'm using my laptop (Lenovo Thinkpad T60) and I have a secondary monitor (which has a different resolution than my laptop screen) connected by VGA. Kubuntu recognizes the monitor and it functions but my desktop is mirrored (i.e. an identical copy) across the dual monitors (which is useless to me). How can I extend my desktop across both monitors? P.S. I googled it but the solutions I found weren't standard, they were hardware specific and you had to manually change system files, etc.. There must be an easier way. edit: Here is a snapshot of the settings.

• Why is CS never a topic of conversation of the layman? [closed]

  - by hydroparadise

  Granted, every profession has it's technicalities. If you are an MD, you better know the anatomy of the human body, and if you are astronomer, you better know your calculus. Yet, you don't have to know these more advance topics to know that smoking might give you lung cancer because of carcinogens or the moon revolves around the earth because of gravity (thank you Discovery Channel). There's sort of a common knowledge (at least in more developed countries) of these more advanced topics. With that said, why are things like recursive descent parsing, BNF, or Turing machines hardly ever mentioned outsided 3000 or 4000 level classes in a university setting or between colleagues? Even back in my days before college in my pursuit of knowledge on how computers work, these very important topics (IMHO) never seem to get the light of day. Many different sources and sites go into "What is a processor?" or "What is RAM?", or "What is an OS?". You might get lucky and discover something about programming languages and how they play a role in how applications are created, but nothing about the tools for creating the language itself. To extend this idea, Dennis Ritchie died shortly after Steve Jobs, yet Dennis Ritchie got very little press compared to Steve Jobs. So, the heart of my question: Does the public in general not care to hear about computer science topics that make the technology in their lives work, or does the computer science community not lend itself to the general public to close the knowledge gap? Am I wrong to think the general public has the same thirst for knowledge on how things work as I do? Please consider the question carefully before answering or vote closing please.

• WCF "DataContext accessed after Dispose"

  - by David Ward

  I have an application with numerous WCF services that make use of LINQ-To-SQL as the data access model. I am having lots of problems with the "DataContext accessed after Dispose" exception. I understand what this exception is and that it is occurring because I have not "initialised" the data that is trying to be accessed. I've read many articles that suggest that I called ToList() on any arrays before the parent object is returned by the service. My issue is that I am getting this exception and I don't know where it is originating from and therefore I don't know what hasn't been initialised. Can anyone advise how best to identify the root cause? (I have used the MS Service Trace Viewer and this doesn't seem to give me any further information)

• python numpy roll with padding

  - by Marshall Ward

  I'd like to roll a 2D numpy in python, except that I'd like pad the ends with zeros rather than roll the data as if its periodic. Specifically, the following code import numpy as np x = np.array([[1, 2, 3],[4, 5, 6]]) np.roll(x,1,axis=1) returns array([[3, 1, 2],[6, 4, 5]]) but what I would prefer is array([[0, 1, 2], [0, 4, 5]]) I could do this with a few awkward touchups, but I'm hoping that there's a way to do it with fast built-in commands. Thanks

• DomainDataSource DataPager with silverlight 3 DataGrid & .Net RIA Services

  - by Dennis Ward

  I have a simple datagrid example with silverlight 3, and am populating it with the .NET ria services using a DomainDataSource along with a DataPager declaratively (nothing in the code-behind), and am experiencing this problem: The LoadSize is 30, and the Page size is 15, and when the page is loaded, the 1st and 2nd page appear correctly, but when I go beyond the 2nd page, nothing shows up in the grid. This used to work in the silverlight 3 beta with the Mix 2009 preview of .NET Ria services, and I've got a really simple example and have verified that the Service on the web project gets called to load a new batch, but the grid doesn't show any data. Can anyone shed any light as to why grid displays data only for the initial load of data and not subsequent batches from the pager? Here's my xaml: <riaControls:DomainDataSource x:Name="ArtistSource" QueryName="GetArtist" AutoLoad="True" LoadSize="30" PageSize="15"> <riaControls:DomainDataSource.DomainContext> <domain:AdminContext /> </riaControls:DomainDataSource.DomainContext> </riaControls:DomainDataSource> <data:DataGrid Grid.Row="1" x:Name="ArtistDataGrid" ItemsSource="{Binding Data, ElementName=ArtistSource}"> </data:DataGrid> <StackPanel Grid.Row="2"> <data:DataPager Source="{Binding Data, ElementName=ArtistSource}" /> </StackPanel>

• AdMob and UINavigationControllers

  - by Ward

  I'm playing around with AdMob and I"m trying to get something going with an auto-rotating view inside a uinavigationcontroller. I have the ad at the top of the screen. Not sure if this is the right approach, but in my LoadView method I have: self.navigationController.view.frame = CGRectMake(0,48,320,432); The navbar appears below the ad. When I rotate the phone to landscape is there a way to get the navbar (which is now across the top) to be 432px wide so it doesn't get cut off under the ad? I tried writing a method that is called when the device orientation changes, but it seems like manipulating the view on the navigationcontroller screws things up for every orientation except portrait. The view keeps getting shorter until it disappears. Thanks, Howie

• Creating a (ClickOnce) setup for VSTO Outlook Add-in

  - by Ward Werbrouck

  So I created an Outlook Add-in and used the click-once setup to deploy it. The setup runs fine when the user is administrator, but otherwise: no go. Running the setup with "run as..." and logging in as admin works, but than the add-in is installed under the admin, not the current user. The addin doesn't show up in outlook. I tried following this guide: http://blogs.msdn.com/mshneer/archive/2008/04/24/deploying-your-vsto-add-in-to-all-users-part-iii.aspx But I get stuck at part I: http://blogs.msdn.com/mshneer/archive/2007/09/04/deploying-your-vsto-add-in-to-all-users-part-i.aspx I follow the examples and start excel as described: Now start Excel application. Examine the registry keys in HKCU hive e.g. you will find two interesting registry keys that appear under your HKCU hive: HKCU\Software\Microsoft\Office\TestKey registry key containing registry value TestValue You now also have HKCU\Software\Microsoft\Office\12.0\User Settings\TestPropagation registry key with Count value set to 1 But on my machine, the keys are not created... What can I try next?

• WPF Style - value based on another control's property

  - by David Ward

  Is it possible to set the BorderBrush property in a style, to the value of the BorderBrush property of an instance of another control? Something like: <Style x:Key="{x:Type Controls:TimePicker}" TargetType="Controls:TimePicker"> <Setter Property="BorderBrush" Value="[ElementName=txtText Property=BorderBrush]"/> </Style> The reason for this is that I'm using Infragistics controls that have a "Theme" that can be changed and I want my custom control to change border style at the same time.

• Embedded views and resources (mvc)

  - by Steve Ward

  Hi I've embedded several views in a library so that I can re-use across projects using this method which works OK: http://www.wynia.org/wordpress/2008/12/aspnet-mvc-plugins/ But one view usings a Javascript file. I've tried marking this as an embedded resource and adding it AssemblyInfo.cs and then referencing this resource using <%= ClientScript.GetWebResourceUrl(this.GetType(), "FullPath.FileName.js")%> This is literally displaying this output in the view WebResource.axd?d=nUxqfqAUQLabLU54W I think this is because Im trying to refer to an embedded resource from an embedded resource. Help appreciated as Im going round in circles.. Steve

• Rewriting URL's in codeigniter with url_title()?

  - by Craig Ward

  I am rewriting my website with codeigniter and have something I want to do but not sure it is possible. I have a gallery on my site powered by the Flickr API. Here is an example of the code I use to display the Landscape pictures: <?php foreach ($landscapes->photoset->photo as $l->photoset->photo) : ?> <a >photoset->photo->farm ?>/<?php echo $l->photoset->photo->server ?>/<?php echo $l->photoset->photo->id ?>/<?php echo $l->photoset->photo->secret ?>/<?php echo $l->photoset->photo->title ?>'> <img class='f_thumb'>photoset->photo->farm ?>.static.flickr.com/<?php echo $l->photoset->photo->server ?>/<?php echo $l->photoset->photo->id ?>_<?php echo $l->photoset->photo->secret ?>_s.jpg' title='<?php echo $l->photoset->photo->title ?>' alt='<?php echo $l->photoset->photo->title ?>' /></a> <?php endforeach; ?> As you can see when a user clicks on a picture I pass over the Farm, Server, ID, Secret and Title elements using URI segments and build the page in the controller using $data['farm'] = $this->uri->segment(3); $data['server'] = $this->uri->segment(4); $data['id'] = $this->uri->segment(5); $data['secret'] = $this->uri->segment(6); $data['title'] = $this->uri->segment(7); Everything works and is fine but the URL’s are a tad long, example “http://localhost:8888/wip/index.php/gallery/focus/3/2682/4368875046/e8f97f61d9/Old Mill House in Donegal” Is there a way to rewrite the URL so its more like “http://localhost:8888/wip/index.php/gallery/focus/Old_Mill_House_in_Donegal” I was looking at using: $url_title = $this->uri->segment(7); $url_title = url_title($url_title, 'underscore', TRUE); But I don’t seem to be able to get it to work. Any ideas?

• Generate a random alphanumeric string in cocoa

  - by Ward

  Hey there, I know this can't be that hard. I've searched, but I can't seem to find a simple solution. I want to call a method, pass it the length and have it generate a random alphanumeric string. Any ideas? Are there any utility libraries out there that may have a bunch of these types of functions? Thanks, Howie

• Cocoa - Enumerate mutable array, removing objects

  - by Ward

  Hey there, I have a mutable array that contains mutable dictionaries with strings for the keys latitude, longitude and id. Some of the latitude and longitude values are the same and I want to remove the duplicates from the array so I only have one object per location. I can enumerate my array and using a second enumeration review each object to find objects that have different ids, but the same latitude and longitude, but if I try to remove the object, I'm muting the array during enumeration. Is there any way to remove objects from an array while enumerating so I only enumerate the current set of objects as the array is updated? Hope this question makes sense. Thanks, Howie

• What is all this stuff in the CKEditor folder?

  - by Ashley Ward

  A while ago I downloaded the latest version (3.1) of the CKEditor text editor. The directory name was ckeditor and I deleted the ckeditor/_source and ckeditor/_samples sub-directories, then I referenced the ckeditor.js file in my html pages, like so : <script type="text/javascript" src="ckeditor/ckeditor.js"></script> this works well. To make config changes, I have been modifying the ckeditor/config.js file. However, as of late, I have been reading various web resources that say 'do not delete the _source' folder and other such ominous messages. What is this _source folder? What is all the stuff at the root of the ckeditor folder? and, What is safe to remove from the folder?

• WCF - Passing CurrentPrincipal in the Header

  - by David Ward

  I have a WCF service that needs to know the Principal of the calling user. In the constructor of the service I have: Principal = OperationContext.Current.IncomingMessageHeaders.GetHeader<MyPrincipal>("myPrincipal", "ns"); and in the calling code I have something like: using (var factory = new ChannelFactory<IMyService>(localBinding, endpoint)) { var proxy = factory.CreateChannel(); using (var scope = new OperationContextScope((IContextChannel)proxy)) { var customHeader = MessageHeader.CreateHeader("myPrincipal", "ns", Thread.CurrentPrincipal); OperationContext.Current.OutgoingMessageHeaders.Add(customHeader); newList = proxy.CreateList(); } } This all works fine. My question is, how can I avoid having to wrap all proxy method calls in the using (var scope...{ [create header and add to OperationContext]? Could I create a custom ChannelFactory that will handle adding the myPrincipal header to the operation context? Something like that would save a whole load of copy/paste which I'd rather not do but I'm not sure how to achieve it:) Thanks

• Proper way to return an array

  - by Ward

  Hey there, I never seem to get this right. I've got a method that returns a mutable array. What is the proper way to return the array and avoid potential memory leaks? If I plan to store the results locally inside another view controller, does that affect the way the array should be returned? Lastly, what if it's just an non-mutable array? Does that require a different technique? thanks, Howie

• UIButton Origin and Device Orientation

  - by Ward

  Hey there, I might be crazy, but for some reason this problem is stumping me. I have a view controller that is set to auto rotate to orientation. Inside I've got two subviews. One is a uibutton. All I want is for my button's origin to stay locked to the bottom-left in portrait and bottom-right in landscape (so it basically stays in the same place). It should also stay in place for portrait upside down and landscape right. Any ideas? Thanks, Howie

• iphone Three20 TTNavigator UITabbarController

  - by Ward

  Not sure if what I want to do makes sense, but I want to take advantage of the UITabBarController and the TTNavigator from Three20. Any tutorials around that demonstrate how this can be done? I understand how to add view controllers to the navigator using the TTURLMap, but do I need to add a navigator for each tabbar item? I'm lost.

• WPF Listbox - Empty List Display Message

  - by David Ward

  Can anyone suggest the best way to display a Textblock (with a text such as "List Empty") so that it's visibility is bound to the Items.Count. I have tried the following code and can't get it to work, so think that I must be doing it wrong. <ListBox x:Name="lstItems" ItemsSource="{Binding ListItems}"> </ListBox> <TextBlock Margin="4" FontStyle="Italic" FontSize="12" Text="List is empty" Visibility="Collapsed"> <TextBlock.Style> <Style TargetType="{x:Type TextBlock}"> <Style.Triggers> <DataTrigger Binding="{Binding ElementName=lstItems, Path=Items.Count}" Value="0"> <Setter Property="Visibility" Value="Visible" /> </DataTrigger> </Style.Triggers> </Style> </TextBlock.Style> </TextBlock>

• NSNumberFormatter crashing iPhone SDK 4.0b2

  - by Ward

  Hey there, I've got an app that's been in the app store for a while and functions perfectly on OS 3.1 - 3.13. However, when tested on 4.0b2 I noticed that it crashes in the same place every time, but only on the device, never on the simulator. I'm using a 3GS to test. On loadView I initialize an NSNumberFormatter object which is declared and retained in the interface so I have access to it everywhere. In my method I call it several times to convert string values into nsnumbers to be stored in a mutable dictionary. Here's an example: [myDictionary setObject:[myStyleFormatter numberFromString:@"1"] forKey:@"hours"]; [myDictionary setObject:[myStyleFormatter numberFromString:@"30"] forKey:@"minutes"]; [myDictionary setObject:[myStyleFormatter numberFromString:@"10"] forKey:@"seconds"]; For some reason it crashes as soon as it tries to set hours. The error is "attempt to insert nil value (key: hours)" Have I been doing something wrong all along? Has the api changed for 4.0b2? Thanks, Howie
