  • Changing the background color of a view in real-time.

    - by Tarmon
    Hey Everyone, I am trying to implement a ListView that is composed of rows that contain a View on the left followed by a TextView to the right of that. I want to be able to change the background color of the first View based on it's position in the ListView. Below is what I have at this point but it doesn't seem to due anything. public class Routes extends ListActivity { String[] ROUTES; TextView selection; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ROUTES = getResources().getStringArray(R.array.routes); setContentView(R.layout.routes); setListAdapter(new IconicAdapter()); selection=(TextView)findViewById(R.id.selection); } public void onListItemClick(ListView parent, View v, int position, long id) { selection.setText(ROUTES[position]); } class IconicAdapter extends ArrayAdapter<String> { IconicAdapter() { super(Routes.this, R.layout.row, R.id.label, ROUTES); } } public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = getLayoutInflater(); View row = inflater.inflate(R.layout.row, parent, false); TextView label = (TextView) row.findViewById(R.id.label); label.setText(ROUTES[position]); View icon = (View) row.findViewById(R.id.icon); switch(position){ case 0: icon.setBackgroundColor(R.color.Red); break; case 1: icon.setBackgroundColor(R.color.Red); break; case 2: icon.setBackgroundColor(R.color.Green); break; case 3: icon.setBackgroundColor(R.color.Green); break; case 4: icon.setBackgroundColor(R.color.Blue); break; case 5: icon.setBackgroundColor(R.color.Blue); break; case 6: icon.setBackgroundColor(R.color.Gray); break; case 7: icon.setBackgroundColor(R.color.Yellow); break; case 8: icon.setBackgroundColor(R.color.Brown); break; case 9: icon.setBackgroundColor(R.color.Brown); break; case 10: icon.setBackgroundColor(R.color.Brown); break; case 11: icon.setBackgroundColor(R.color.Purple); break; case 12: icon.setBackgroundColor(R.color.Red); break; case 13: icon.setBackgroundColor(R.color.Gold); break; case 14: icon.setBackgroundColor(R.color.Orange); break; } return(row); } } Any input is appreciated and if you have any questions don't hesitate to ask!

  • SQL Server Licensing in a VMware vSphere Cluster

    - by Helvick
    If I have SQL Server 2008 instances running in virtual machines on a VMware vSphere cluster with vMotion\DRS enabled so that the VM's can (potentially) run on any one of the physical servers in the cluster what precisely are the license requirements? For example assume that I have 4 physical ESX Hosts with dual physical CPU's and 3 separate single vCPU Virtual Machines running SQL Server 2008 running in that cluster. How many SQL Standard Processor licenses would I need? Is it 3 (one per VM) or 12 (one per VM on each physical host) or something else? How many SQL Enterprise Processor licenses would I need? Is it 3 (one per VM) or 8 (one for each physical CPU in the cluster) or, again, something else? The range in the list prices for these options goes from $17k to $200k so getting it right is quite important. Bonus question: If I choose the Server+CAL licensing model do I need to buy multiple Server instance licenses for each of the ESX hosts (so 12 copies of the SQL Server Standard server license so that there are enough licenses on each host to run all VM's) or again can I just license the VM and what difference would using Enterprise per server licensing make? Edited to Add Having spent some time reading the SQL 2008 Licensing Guide (63 Pages! Includes Maps!*) I've come across this: • Under the Server/CAL model, you may run unlimited instances of SQL Server 2008 Enterprise within the server farm, and move those instances freely, as long as those instances are not running on more servers than the number of licenses assigned to the server farm. • Under the Per Processor model, you effectively count the greatest number of physical processors that may support running instances of SQL Server 2008 Enterprise at any one time across the server farm and assign that number of Processor licenses And earlier: ..For SQL Server, these rule changes apply to SQL Server 2008 Enterprise only. By my reading this means that for my 3 VM's I only need 3 SQL 2008 Enterprise Processor Licenses or one copy of Server Enterprise + CALs for the cluster. By implication it means that I have to license all processors if I choose SQL 2008 Standard Processor licensing or that I have to buy a copy of SQL Server 2008 Standard for each ESX host if I choose to use CALs. *There is a map to demonstrate that a Server Farm cannot extend across an area broader than 3 timezones unless it's in the European Free Trade Area, I wasn't expecting that when I started reading it.

  • ssh, "Last Login", `last` and OS X

    - by allentown
    I have hit the googles as much as I can on this, being specific to OS X, I am not finding an answer. Nothing is wrong, but curiosity levels are high. $ssh [email protected] Password: Last login: Wed Apr 7 21:28:03 2010 from my-laptop.local ^lonely tylenol^ Line 1 is my command line 2 is the shell asking for the password line 3 is where my question comes from line 4 comes out of /etc/motd I can find nothing in ~/ of an of the .bash* files that contains the string "Last Login", and would like to alter it. It performs some type of hostname lookup, which I can not determine. If I ssh to another host: $ssh [email protected] Last login: Wed Apr 7 21:14:51 2010 from 123-234-321-123-some.cal.isp.net.example hi there, you are on box 456 line 1 is my command line 2 is again, where my question comes from line 3 is from /etc/motd *The dash'd IP address is not reversed On this remote host, I have ~/.ssh and it's corresponding keys set up, so there was no password request Where is the "Last Login:" coming from, where does the date stamp come from, and most importantly, where does the hostname come from? While on [email protected] (box 456) $echo hostname remote.location.example456.com Or with dig, to make sure I have rDNS/PTR set up, for which I am not authoritative, but my ISP has correctly set... $dig -x 123.234.321.123 PTR remote.location.example456.com or $dig PTR 123.321.234.123.in-addr.arpa. +short remote.location.example456.com. my previous hostname used to be 123-234-321-123-some.cal.isp.net.example, which I set with hostname -s remote.location.example456.com, because it was obnoxious to see such a long name. That solves the value of $echo hostname which now returns remote.location.example456.com. Mac OS X, 10.6 is this case, does seem to honor: touch ~/.hushlogin If leave that file empty, I get nothing on the shell when I login. I want to know what controls the host resolution of the IP, and how it is all working. For example, running last reports a huge list of my logins, which have obtusely long hostnames, when they would be preferable to just be remote.location.example456.com. More confusing to me, reading the man page for wtmp and lastlog, it looks like lastlog is not used on OS X, /var/log/lastlog does not exist. Actually, none of these exist on 10.5 or 10.6: /var/run/utmp The utmp file. /var/log/wtmp The wtmp file. /var/log/lastlog The lastlog file. If I am to assume that the system is doing some kind of reverse lookup, I certainly do not know what it is, as it is not an accurate one.

  • Silverlight and Unexpected Font Sizes

    - by Eric J.
    Someone please teach me to fish here... I'm just learning Silverlight and have ran into a few situations where the font size actually used is drastically different than I would expect. There's probably something conceptual that I'm missing. Case A In one instance, I have defined a user control that presents a Label to show text. If one clicks on the label, the label (that is in a stack panel, in the user control) is replaced with a TextBox. When used at the top of a page (as in the example below with lblName) the label text is very small (around 8 points). When clicked on, the text box that replaces the label uses the specified fonts size. That same user control, used in different parts of the app, uses the same font for Label and TextBox. <Grid x:Name="LayoutRoot" Background="White"> <Grid.RowDefinitions> <RowDefinition Height="33" /> <RowDefinition Height="267*" /> </Grid.RowDefinitions> <StackPanel Height="Auto" HorizontalAlignment="Left" Name="stackPanel" VerticalAlignment="Top" Width="Auto" Grid.Row="1" /> <my:EditLabel Height="33" HorizontalAlignment="Left" x:Name="lblName" VerticalAlignment="Top" Width="Auto" FlexText="{Binding Name, Mode=TwoWay}" FontSize="20" MinHeight="24" /> </Grid> Case B I'm using the LiquidMenu.Menu control to pop up a menu when a button is pressed. The font looks huge compared to the rest of my page (maybe 36 points?). I tried forcing it to a very small by explicitly setting it to 8pt, but that had no effect. <Grid x:Name="LayoutRoot" Background="{x:Null}"> <StackPanel x:Name="labelStackPanel" Orientation="Horizontal"> <TextBlock Height="24" HorizontalAlignment="Left" Name="labelText" VerticalAlignment="Top" Width="200" Text="(Value Goes Here)" /> </StackPanel> <liquidMenu:Menu x:Name="popupMenu" Canvas.Left="40" Canvas.Top="40" ItemSelected="MenuList_ItemSelected" Visibility="Collapsed" Height="Auto" FontSize="8"> <liquidMenu:MenuItem ID="delete" Icon="Images/Delete10.png" Text="Delete" Shortcut="Del" /> <liquidMenu:MenuItem ID="exclusive" Icon="" Text="Exclusive" Shortcut="Ctrl+E" /> <liquidMenu:MenuItem ID="properties" Icon="" Text="Properties" Shortcut="Ctrl+P" /> </liquidMenu:Menu> </Grid> Answers to these specific issues are great, a new way to think about this type of issue so that I understand how to control font size is better.

  • Using SetWindowTheme() on controls in WindowsFormsHost in WPF?

    - by Eric Smith
    I have an application I'm developing which closely mirrors Windows 7's Device Stage. In Device Stage, beneath the main banner there is a ListView containing actions embodied as ListViewItems. In my WPF application, I used WindowsFormsHost to host a WinForms ListView so that I could use SetWindowTheme() on it and apply Windows Vista/7 styling to it. This, however, does not work and doesn't achieve the same effect it does when used in Windows Forms. How can I achieve the Windows 7 look on a ListView in WPF? I'm not looking to create a custom style then apply it because frankly that's too much of a pain in the ass to continue using WPF for this app. Thanks! :)

  • Entity Framework 4 Code First and the new() Operator

    - by Eric J.
    I have a rather deep hierarchy of objects that I'm trying to persist with Entity Framework 4, POCO, PI (Persistence Ignorance) and Code First. Suddenly things started working pretty well when it dawned on me to not use the new() operator. As originally written, the objects frequently use new() to create child objects. Instead I'm using my take on the Repository Pattern to create all child objects as needed. For example, given: class Adam { List<Child> children; void AddChildGivenInput(string input) { children.Add(new Child(...)); } } class Child { List<GrandChild> grandchildren; void AddGrandChildGivenInput(string input) { grandchildren.Add(new GrandChild(...)); } } class GrandChild { } ("GivenInput" implies some processing not shown here) I define an AdamRepository like: class AdamRepository { Adam Add() { return objectContext.Create<Adam>(); } Child AddChildGivenInput(Adam adam, string input) { return adam.children.Add(new Child(...)); } GrandChild AddGrandchildGivenInput(Child child, string input) { return child.grandchildren.Add(new GrandChild(...)); } } Now, this works well enough. However, I'm no longer "ignorant" of my persistence mechanism as I have abandoned the new() operator. Additionally, I'm at risk of an anemic domain model since so much logic ends up in the repository rather than in the domain objects. After much adieu, a question: Or rather several questions... Is this pattern required to work with EF 4 Code First? Is there a way to retain use of new() and still work with EF 4 / POCO / Code First? Is there another pattern that would leave logic in the domain object and still work with EF 4 / POCO / Code First? Will this restriction be lifted in later versions of Code First support? Sometimes trying to go the POCO / Persistence Ignorance route feels like swimming upstream, other times it feels like swimming up Niagra Falls.

  • applicationSettings and Web.config

    I have a DLL that provides logging that I use for WebForms projects and now wish to use it in an ASP.Net MVC 2 project. Some aspects of that DLL are configured in app.config: <configuration> <configSections> <section name="Tools.Instrumentation.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> </sectionGroup> </configSections> <applicationSettings> <Tools.Instrumentation.Properties.Settings> <setting name="LogLevel" serializeAs="String"> <value>DEBUG</value> </setting> <setting name="AppName" serializeAs="String"> <value>MyApp</value> </setting> <setting name="Port" serializeAs="String"> <!--value>33333</value--> <value>0</value> </setting> </Tools.Instrumentation.Properties.Settings> </configuration> However, when I create a similar entry in Web.config, I get the error: Unrecognized configuration section applicationSettings My two-part question: How do I make this config entry work in Web.config? Where can I read up on the conceptual differences between WinForms configuration and ASP.Net configuration?

  • EF 4, POCO and AddOrUpdate

    - by Eric J.
    I'm trying to create a method on an EF 4 POCO repository called AddOrUpdate. The idea is that the business layer can pass in a POCO object and the persistence framework will add the object if it is new (not yet in the database), else will update the database (once SaveChanges() is called) with the new value. This is similar to some other questions I have asked about EF, but I'm only about 80% there in understanding this so please forgive partial duplication. The part I'm missing is how to update the object graph in my ObjectContext/associated ObjectSet for the passed-in business object once I have determined that the business object indeed already exists in the database (and now has been loaded thanks to TryGetObjectByKey). ApplyCurrentValues sounds sort of like what I want, but it only copies scalar values and doesn't seem intended to update the object graph in the ObjectContext/ObjectSet. Because of my particular use case I don't care about concurrency right now. public void AddOrUpdate(BO biz) { object obj; EntityKey ek = Ctx.CreateEntityKey(mySetName, biz); bool found = Ctx.TryGetObjectByKey(ek, out obj); if (found) { // How do I do what this method name implies? Biz is a parent with children. mySet.TellTheSetToUpdateThisObject(biz); } else { mySet.AddObject(biz); } Ctx.DetectChanges(); }

  • "Upgrade current target for ipad" is grayed out (disabled)?

    I'm trying to create a universal iPhone/iPad app using this method: http://www.enscand.com/roller/enscand/entry/ready_for_ipad which is also described all over the web. My problem is that the "Upgrade current target for iPad" line is grayed out and doesn't appear at all when I right click the target. I'm working on an app that I inherited from someone, and have tried this with an app that I wrote entirely myself (no problems on that one). And yes, I'm sure that I'm selecting the target. Just wondering if anyone has any insight into what checks are being run that would cause this option to be unavailable.

  • Synchronizing Asynchronous request handlers in Silverlight environment

    - by Eric Lifka
    For our senior design project my group is making a Silverlight application that utilizes graph theory concepts and stores the data in a database on the back end. We have a situation where we add a link between two nodes in the graph and upon doing so we run analysis to re-categorize our clusters of nodes. The problem is that this re-categorization is quite complex and involves multiple queries and updates to the database so if multiple instances of it run at once it quickly garbles data and breaks (by trying to re-insert already used primary keys). Essentially it's not thread safe, and we're trying to make it safe, and that's where we're failing and need help :). The create link function looks like this: private Semaphore dblock = new Semaphore(1, 1); // This function is on our service reference and gets called // by the client code. public int addNeed(int nodeOne, int nodeTwo) { dblock.WaitOne(); submitNewNeed(createNewNeed(nodeOne, nodeTwo)); verifyClusters(nodeOne, nodeTwo); dblock.Release(); return 0; } private void verifyClusters(int nodeOne, int nodeTwo) { // Run analysis of nodeOne and nodeTwo in graph } All copies of addNeed should wait for the first one that comes in to finish before another can execute. But instead they all seem to be running and conflicting with each other in the verifyClusters method. One solution would be to force our front end calls to be made synchronously. And in fact, when we do that everything works fine, so the code logic isn't broken. But when it's launched our application will be deployed within a business setting and used by internal IT staff (or at least that's the plan) so we'll have the same problem. We can't force all clients to submit data at different times, so we really need to get it synchronized on the back end. Thanks for any help you can give, I'd be glad to supply any additional information that you could need!

    After adding the new facebook like button to my page, it no longer validates using XHTML strict. The two errors I come across are: 1. All of the "meta property" tags say that "there is no attribute "property"" 2. All of the variables used in the like button line are listed that there are no attributes for it. The line is as follows:

  • Paperclip and tempfile with Rails

    - by Eric Koslow
    I'm trying to write a rails application where users can upload images, but Paperclip doesn't seem to be working for me. I've gone through all the basic steps (added has_attached_file, the migration, making the form multipart) but I keep getting the same error whenever I try uploading an image: can't convert nil into Integer Looking at the top of the stack ...rails3/lib/paperclip/processor.rb:46:in `sprintf' ...rails3/lib/paperclip/processor.rb:46:in `make_tmpname' .../ruby-1.9.2-head/lib/ruby/1.9.1/tmpdir.rb:154:in `create' .../ruby-1.9.2-head/lib/ruby/1.9.1/tempfile.rb:134:in `initialize' It seems the problem is in the tempfile. My code: _form.rb <%= form_for @high_school, :html => {:multipart => true} do |f| %> <%= f.error_messages %> ... <div class="field"> <%= f.file_field :photo %> </div> <div class="actions"> <%= f.submit %> </div> <% end %> model/high_school.rb ... validates_length_of :password, :minimum => 4, :allow_blank => true has_attached_file :photo has_many :students ... Is this a known problem? I basically followed the instructions from the github to the letter. My environment: Rails3 and Ruby 1.9.2dev Thank you!

  • How to fix an endpoint/configuration error using WCF in VB.NET

    - by Eric
    I'm working with a small web page that is meant to assist the users of my application. This web page takes a file and sends it to a central server, which then does something with the data and returns a result. I created this application some time ago and am coming back to it recently. I am getting some kind of configuration error right now, although this application used to work. When it stopped working, whenever I ran the page and sent the data to the central server, I would get this error: "Could not find default endpoint element that references contract 'CentralService.ICwCentralService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element." Looking at some other issues on the net, I thought I might have had the answer. The service reference to the endpoint was contained in a separate project from the code that called it, but the configuration file in that project had no information about the endpoint. So, I added these entries to the web.config file in the main project: <system.serviceModel> <bindings> <wsHttpBinding> <binding name="wsHttpEndpoint" closeTimeout="00:01:00" openTimeout="00:0:10" receiveTimeout="01:10:00" sendTimeout="01:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="999999999" maxReceivedMessageSize="999999999" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="999999999" maxStringContentLength="999999999" maxArrayLength="999999999" maxBytesPerRead="999999999" maxNameTableCharCount="999999999" /> <reliableSession ordered="true" inactivityTimeout="01:10:00" enabled="false" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://localhost:22269/CwCentralService.svc" binding="wsHttpBinding" bindingConfiguration="wsHttpEndpoint" contract="CentralService.ICwCentralService" name="wsHttpEndpoint"> <identity> <servicePrincipalName /> </identity> </endpoint> </client> </system.serviceModel> Now, if I run it, I'm still getting an error: "The remote server returned an unexpected response: (400) Bad Request." The strange thing is, though, I took those entries from another project that contacts the central server. That application has no problems contacting the central server using these settings. It's not a web page application, but I don't see how that would require these settings to change. I cannot tell what started causing these errors or when. I assume its something that changed outside of the application (e.g. the libraries referenced) that requires an update to the configuration in the application. I am currently using .NET 3.0 for all of my applications. Any help would be appreciated.

  • VS2010 Extension like Smart Paster?

    - by Eric J.
    Alex Papadimoulis' Smart Paster is a great little tool that can paste text in programmer-friendly ways (e.g. as a StringBuilder, as a language-specific string literal, etc.). However, it doesn't seem to be available for VS2010. Anyone know of a similar extension or of plans to port Smart Paster?
