  • Hive Based Registry in Flash

    - by Psychic
    To start with I'll say I've read the post here and I'm still having trouble. I'm trying to create a CE6 image with a hive-based registry that actually stores results through a reboot. I've ticked the hive settings in the catalog items. In common.reg, I've set the location of the hive ([HKEY_LOCAL_MACHINE\init\BootVars] "SystemHive") to "Hard Drive\Registry" (Note: the flash shows up as a device called "Hard Drive") In common.reg, I've set "Flags"=dword:3 in the same place to get the device manager loaded along with the storage manager I've verified that these settings are wrapped in "; HIVE BOOT SECTION" This is where it starts to fall over. It all compiles fine, but on the target system, when it boots, I get: A directory, called "Hard Disk" where a registry is put A device, name called "Hard Disk2" where the permanent flash is Any changes made to the registry are lost on a reboot What am I still missing? Why is the registry not being stored on the flash? Strangly, if I create a random file/directory in the registry directory, it is still there after a reboot, so even though this directory isn't on the other partition (where I tried to put it), it does appear to be permanent. If it is permanent, why don't registry settings save (ie Ethernet adapter IP addresses?) I'm not using any specific profiles, so I'm at a loss as to what the last step is to make this hive registry a permanent store.

  • "Instance variable 'xxx' accessed in class method....why?

    - by Michael Levy
    So please forgive me as I am very new to stackoverflow and to ios programming in general. I am attempting to change the text of a button i have, replacing current text with a date string (dateStringForInput) I am passing in from another class. The button is called myTodayButton and is declared in my .h file for my class inputMilesViewController... @property (strong, nonatomic) IBOutlet UIButton *myTodayButton; Below is the code from my .m. +(void) changeButtonText:(NSString*) dateStringForInput{ NSLog(@"we got to changebuttontext"); [_myTodayButton setTitle:dateStringForInput forState:UIControlStateNormal]; } I am getting the following error "Instance variable "_myTodayButton" accessed in class method. I understand that this is written in a class method rather than an instance method but i cant figure out how to get this change to happen. the button which prompts this call to changeButtonText is in the other class which is creating dateStringForInput. please help! thanks so much! be gentle with me....a bit overwhelmed . :-)

  • Cross-table linq query with EF4/POCO

    - by Basiclife
    Hi All, I'm new to EF(any version) and POCO. I'm trying to use POCO entities with a generic repository in a "code-first" mode(?) I've got some POCO Entities (no proxies, no lazy loading, nothing). I have a repository(of T as Entity) which provides me with basic get/getsingle/getfirst functionality which takes a lambda as a parameter (specifically a System.Func(Of T, Boolean)) Now as I'm returning the simplest possible POCO object, none of the relationship parameters work once they've been retrieved from the database (as I would expect). However, I had assumed (wrongly) that my lambda query passed to the repository would be able to use the links between entities as it would be executed against the DB before the simple POCO entities are generated. The flow is: GUI calls: Public Function GetAllTypesForCategory(ByVal CategoryID As Guid) As IEnumerable(Of ItemType) Return ItemTypeRepository.Get(Function(x) x.Category.ID = CategoryID) End Function Get is defined in Repository(of T as Entity): Public Function [Get](ByVal Query As System.Func(Of T, Boolean)) As IEnumerable(Of T) Implements Interfaces.IRepository(Of T).Get Return ObjectSet.Where(Query).ToList() End Function The code doesn't error when this method is called but does when I try to use the result set. (This seems to be a lazy loading behaviour so I tried adding the .ToList() to force eager loading - no difference) I'm using unity/IOC to wire it all up but I believe that's irrelevant to the issue I'm having NB: Relationships between entities are being configured properly and if I turn on proxies/lazy loading/etc... this all just works. I'm intentionally leaving all that turned off as some calls to the BL will be from a website but some will be via WCF - So I want the simplest possible objects. Also, I don't want a change in an object passed to the UI to be committed to the DB if another BL method calls Commit() Can someone please either point out how to make this work or explain why it's not possible? All I want to do is make sure the lambda I pass in is performed against the DB before the results are returned Many thanks. In case it matters, the container is being populated with everything as shown below: Container.AddNewExtension(Of EFRepositoryExtension)() Container.Configure(Of IEFRepositoryExtension)(). WithConnection(ConnectionString). WithContextLifetime(New HttpContextLifetimeManager(Of IObjectContext)()). ConfigureEntity(New CategoryConfig(), "Categories"). ConfigureEntity(New ItemConfig()). ... )

  • Check username and password in LINQ query

    - by b0x0rz
    this linq query var users = from u in context.Users where u.UserEMailAdresses.Any(e1 => e1.EMailAddress == userEMail) && u.UserPasswords.Any(e2 => e2.PasswordSaltedHash == passwordSaltedHash) select u; return users.Count(); returns: 1 even when there is nothing in password table. how come? what i am trying to do is get the values of email and passwordHash from two separate tables (UserEMailAddresses and UserPasswords) linked via foreign keys to the third table (Users). it should be simple - checking if email and password mach from form to database. but it is not working for me. i get 1 (for count) even when there are NO entries in the UserPasswords table. is the linq query above completely wrong, or...?

  • Setting a WebControls TabIndex based on the ControlId of another control

    - by Daniel Ballinger
    I have an ASP.NET Webforms site that is regularly having features added. The majority of time a new WebControl is added to the page and I need to increment the TabIndex to all subsequent controls on the page. I'd prefer a more robust solution than choosing an arbitrary gap between the initial assigned tab indexes. Setting the tab indexes using the designer tab order functionality is one option but I'd prefer to stay in the source view. Ideally, if I had three check boxes I'd like to be able to define the tabindex based off the previous controls tabindex. Then I'd only need to insert the new control and change one existing control. <asp:CheckBox ID="checkBoxA" runat="server" TabIndex="0"/> <asp:CheckBox ID="checkBoxB" runat="server" TabIndexAfterControlId="checkBoxA"/> <asp:CheckBox ID="checkBoxC" runat="server" TabIndexAfterControlId="checkBoxB"/> My first thought was to extend System.Web.UI.WebControls.WebControl with a new property, but extension properties aren't supported.

  • Why doesn't EnumerableRowCollection<DataRow>.Select() compile like this?

    - by David Fox
    This works: from x in table.AsEnumerable() where x.Field<string>("something") == "value" select x.Field<decimal>("decimalfield"); but, this does not: from x in table.AsEnumerable() .Where(y=>y.Field<string>("something") == "value") .Select(y=>y.Field<decimal>("decimalfield")); I also tried: from x in table.AsEnumerable() .Where(y=>y.Field<string>("something") == "value") .Select(y=>new { name = y.Field<decimal>("decimalfield") }); Looking at the two overloads of the .Select() method, I thought the latter two should both return EnumerableRowCollection, but apparently I am wrong. What am I missing?

  • Translate query to NHibernate

    - by Rob Walker
    I am trying to learn NHibernate, and am having difficulty translating a SQL query into one using the criteria API. The data model has tables: Part (Id, Name, ...), Order (Id, PartId, Qty), Shipment (Id, PartId, Qty) For all the parts I want to find the total quantity ordered and the total quantity shipped. In SQL I have: select shipment.part_id, sum(shipment.quantity), sum(order.quantity) from shipment cross join order on order.part_id = shipment.part_id group by shipment.part_id Alternatively: select id, (select sum(quantity) from shipment where part_id = part.id), (select sum(quantity) from order where part_id = part.id) from part But the latter query takes over twice as long to execute. Any suggestions on how to create these queries in (fluent) NHibernate? I have all the tables mapped and loading/saving/etc the entities works fine.

  • When overriding initWithCoder is it always necessary to call [super initWithCoder: coder]

    - by Evan
    In this code I am loading a View Controller (and associated View) from a .xib: -(id)initWithCoder:(NSCoder *)coder { [super initWithCoder:coder]; return self; } This successfully works, but I do not really understand what the line [super initWithCoder:coder] is accomplishing. Is that initializing my View Controller after my View has been initialized? Please be as explicit as possible when explaining. Thanks.

  • Static functions vs const functions

    - by baash05
    I'm looking at a member function int funct(int x) const; And I'm wondering if static int funct(int x); would be better. If a member function doesn't use any of the member variables should it be static. Are there any things that would discourage this?

  • How to do this GQL query in JDO

    - by TheDon
    I have about 50k entities stored in appengine. I am able to look up an individual record via the GQL admin interface with a query like: SELECT * FROM Pet where __key__ = KEY( 'Pet','Fido') But I'm having trouble figuring out how to do a batch version of this via JDO. Right now I have this: PersistenceManager pm = ...; for(Pet pet : pets) { for(String k : getAllAliases(pet)) { keys.add(KeyFactory.createKeyString(Pet.class.getSimpleName(), k)); } } Query q = pm.newQuery("select from " + Pet.class.getName() + " where id == :keys"); List<Pet> petlist = (List<Pet>) q.execute(keys); But though 'Fido' works in the GQL case, it returns nothing when I use that Java + JDO code. What am I doing wrong?

  • How to query Entities in Entity Framework 4

    - by Picflight
    In VS2008, I think it is EF1.0, this works just fine. string queryString = @"SELECT VALUE USERS FROM ProjectDBEntities.Users AS User INNER JOIN ProjectDBEntities.Favorites AS F ON F.FavUserId = User.UserId WHERE F.UserId = " + 3 + " ORDER BY F.CreateDate DESC "; System.Data.Objects.ObjectQuery<User> usersQuery = new System.Data.Objects.ObjectQuery<User>(queryString, context).Include("Detail"); //int count = usersQuery.Count(); foreach (User result in usersQuery) Console.WriteLine("User Name: {0}", result.UserName); Same code in VS2010 EF4 it crashes on the foreach loop with the following error: The result type of the query is neither an EntityType nor a CollectionType with an entity element type. An Include path can only be specified for a query with one of these result types.

  • Why is Html.DropDownList() producing <select name="original_name.name"> instead of just <select name

    - by DanM
    I have an editor template whose job is to take a SelectList as its model and build a select element in html using the Html.DropDownList() helper extension. I'm trying to assign the name attribute for the select based on a ModelMetadata property. (Reason: on post-back, I need to bind to an object that has a different property name for this item than the ViewModel used to populate the form.) The problem I'm running into is that DropDownList() is appending the name I'm providing instead of replacing it, so I end up with names like categories.category instead of category. Here is some code for you to look at... SelectList.ascx <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.Web.Mvc.SelectList>" %> <%= Html.DropDownList( (string)ViewData.ModelMetadata.AdditionalValues["PropertyName"], Model) %> Resulting HTML <select id="SkillLevels_SkillLevel" name="SkillLevels.SkillLevel"> <option value="1">High</option> <option value="2">Med</option> <option selected="selected" value="3">Low</option> </select> Expected HTML <select id="SkillLevels_SkillLevel" name="SkillLevel"> <option value="1">High</option> <option value="2">Med</option> <option selected="selected" value="3">Low</option> </select> Also tried <%= Html.Encode((string)ViewData.ModelMetadata.AdditionalValues["PropertyName"])%> ...which resulted in "SkillLevel" (not "SkillLevels.SkillLevel"), proving that the data stored in metadata is correct. and <%= Html.DropDownList( (string)ViewData.ModelMetadata.AdditionalValues["PropertyName"], Model, new { name = (string)ViewData.ModelMetadata.AdditionalValues["PropertyName"] }) %> ...which still resulted in <select name=SkillLevels.Skilllevel>. Questions What's going on here? Why does it append the name instead of just using it? Can you suggest a good workaround? Update: I ended up writing a helper extension that literally does a find/replace on the html text: public static MvcHtmlString BindableDropDownListForModel(this HtmlHelper helper) { var propertyName = (string)helper.ViewData.ModelMetadata.AdditionalValues["PropertyName"]; var compositeName = helper.ViewData.ModelMetadata.PropertyName + "." + propertyName; var rawHtml = helper.DropDownList(propertyName, (SelectList)helper.ViewData.Model); var bindableHtml = rawHtml.ToString().Replace(compositeName, propertyName); return MvcHtmlString.Create(bindableHtml); }

  • Access static method from non static class possible in java and not in c#

    - by sagar_kool
    Access static method from non static class with object. It is not possible in C#. Where it is done by JAVA. How it works? example of java /** * Access static member of the class through object. */ import java.io.*; class StaticMemberClass { // Declare a static method. public static void staticDisplay() { System.out.println("This is static method."); } // Declare a non static method. public void nonStaticDisplay() { System.out.println("This is non static method."); } } class StaticAccessByObject { public static void main(String[] args) throws IOException { // call a static member only by class name. StaticMemberClass.staticDisplay(); // Create object of StaticMemberClass class. StaticMemberClass obj = new StaticMemberClass(); // call a static member only by object. obj.staticDisplay(); // accessing non static method through object. obj.nonStaticDisplay(); } } Output of the program: This is static method. This is static method. This is non static method. How to do this in C#? thanks in advance..

  • How to optimize simple linked server select query?

    - by tomaszs
    Hello, I have a table called Table with columns: ID (int, primary key, clustered, unique index) TEXT (varchar 15) on a MSSQL linked server called LS. Linked server is on the same server computer. And: When I call: SELECT ID, TEXT FROM OPENQUERY(LS, 'SELECT ID, TEXT FROM Table') It takes 400 ms. When I call: SELECT ID, TEXT FROM LS.dbo.Table It takes 200 ms And when I call the query directly while being at LS server: SELECT ID, TEXT FROM dbo.Table It takes 100 ms. In many places i've read that OPENQUERY is faster, but in this simple case it does not seem to work. What can I do to make this query faster when I call it from another server, not LS directly?

  • TVirtualStringTree - resetting non-visual nodes and memory consumption

    - by Remy Lebeau - TeamB
    I have an app that loads records from a binary log file and displays them in a virtual TListView. There are potentially millions of records in a file, and the display can be filtered by the user, so I do not load all of the records in memory at one time, and the ListView item indexes are not a 1-to-1 relation with the file record offsets (List item 1 may be file record 100, for instance). I use the ListView's OnDataHint event to load records for just the items the ListView is actually interested in. As the user scrolls around, the range specified by OnDataHint changes, allowing me to free records that are not in the new range, and allocate new records as needed. This works fine, speed is tolerable, and the memory footprint is very low. I am currently evaluating TVirtualStringTree as a replacement for the TListView, mainly because I want to add the ability to expand/collapse records that span multiple lines (I can fudge it with the TListView by incrementing/decrementing the item count dynamically, but this is not as straight forward as using a real tree). For the most part, I have been able to port the TListView logic and have everything work as I need. I notice that TVirtualStringTree's virtual paradigm is vastly different, though. It does not have the same kind of OnDataHint functionality that TListView does (I can use the OnScroll event to fake it, which allows my memory buffer logic to continue working), and I can use the OnInitializeNode event to associate nodes with records that are allocated. However, once a tree node is initialized, it sees that it remains initialized for the lifetime of the tree. That is not good for me. As the user scrolls around and I remove records from memory, I need to reset those non-visual nodes without removing them from the tree completely, or losing their expand/collapse states. When the user scrolls them back into view, I can re-allocate the records and re-initialize the nodes. Basically, I want to make TVirtualStringTree act as much like TListView as possible, as far as its virtualization is concerned. I have seen that TVirtualStringTree has a ResetNode() method, but I encounter various errors whenever I try to use it. I must be using it wrong. I also thought of just storing a data pointer inside each node to my record buffers, and I allocate and free memory, update those pointers accordingly. The end effect does not work so well, either. Worse, my largest test log file has ~5 million records in it. If I initialize the TVirtualStringTree with that many nodes at one time (when the log display is unfiltered), the tree's internal overhead for its nodes takes up a whopping 260MB of memory (without any records being allocated yet). Whereas with the TListView, loading the same log file and all the memory logic behind it, I can get away with using just a few MBs. Any ideas?

  • - Button's positioning on UIToolBar in IB -

    - by gotye
    Hey guys, As a fervent adept of IB, I created a UIToolBar (in IB of course) and added to it a few buttons. So far so good ... but then I tried to move each of them to the right position but IB doesn't let me do it ... Each time I try to scroll them IB moves them back to the former position ! Is there a way to choose their position in IB ? If not, could you give me a piece of code for me to choose their position programatically ? (sigh :D) Thanks, Gotye.
