  • Use Any() and Count() in Dynamic Linq

    - by ArpanDesai
    I am trying to write dynamic Linq Library query to fetch record on condition, Customers who has order count is greater than 3 and ShipVia field equal 2. Below is my syntax what i have tried. object[] objArr = new object[10]; objArr[0] = 1; IQueryable<Customer> test = db.Customers.Where("Orders.Count(ShipVia=2)", objArr); and IQueryable<Customer> test = db.Customers.Where("Orders.Any(ShipVia=2).Count()", objArr); But both are not working. In second query Any returns true so it won't work with Count. Suggest me a way to implement this.

  • How can I overwrite a System.Drawing.Bitmap onto an existing GDI bitmap?

    - by MusiGenesis
    If I have a .Net Bitmap, I can create from it a GDI bitmap by calling the Bitmap's GetHbitmap() method. Bitmap bmp = new Bitmap(100, 100); IntPtr gdiBmp = bmp.GetHbitmap(); This works fine, but every time you call GetHbitmap, Windows has to allocate new memory for the object that gdiBmp references. What I'd like to do - if possible - is write a function (I know PInvoke will be necessary here) that also generates a GDI bitmap copy of a Bitmap, but that uses an existing object instead of allocating a new one. So it would look something like this (if it were an extension method of Bitmap): //void OverwriteHbitmap(IntPtr gdi) Bitmap bmp1 = new Bitmap(100, 100); IntPtr gdi1 = bmp1.GetHbitmap(); Bitmap bmp2 = new Bitmap(100, 100); bmp2.OverwriteHbitmap(gdi1); How can I do this? I assume I'll need to know the structure of a GDI bitmap, and probably I can use LockBits and BitmapData for this, but I'm not sure exactly how.

  • In LINQ-SQL, wrap the DataContext is an using statement - pros cons

    - by hIpPy
    Can someone pitch in their opinion about pros/cons between wrapping the DataContext in an using statement or not in LINQ-SQL in terms of factors as performance, memory usage, ease of coding, right thing to do etc. Update: In one particular application, I experienced that, without wrapping the DataContext in using block, the amount of memory usage kept on increasing as the live objects were not released for GC. As in, in below example, if I hold the reference to List of q object and access entities of q, I create an object graph that is not released for GC. DataContext with using using (DBDataContext db = new DBDataContext()) { var q = from x in db.Tables where x.Id == someId select x; return q.toList(); } DataContext without using and kept alive DBDataContext db = new DBDataContext() var q = from x in db.Tables where x.Id == someId select x; return q.toList(); Thanks.

  • Where is my SQLite database?

    - by Brian Ramsay
    I have installed SQLite version 3 into a non-standard location on my dreamhost user account. I compiled it and installed it just fine, and it works with $db=new SQLiteDatabase("db.foont"); I can create tables and insert and read data with the SQLiteDatabase object just fine. However, I want to use PDO. My problem is that PDO requires an absolute path to the database specified in the connection. e.g., 'sqlite:/path/to/db.sq3' a) this is dumb - if the other object can figure out where the db is without an absolute path why can't PDO's sqlite driver - but that's not my question. b) where the heck is my database being stored? I can't find it anywhere in my user filesystem, and I'm pretty sure I don't have access to anything else.

  • How would you pass objects with MVC and jQuery AJAX?

    - by Ken
    I am finally experimenting and trying to learn MVC after years of asp.net. I am used to using asp.net AJAX PageMethods where you can pass an object that automagically gets parsed to whatever type the parameter is in that method. Javascript: PageMethods.AddPerson({First:"John",Last:"Doe"}); Code-Behind: [WebMethod] public static Result AddPerson(Person objPerson) { return Person.Save(); } How would do this using MVC and jQuery? Did just have to send strings and parse the json to object?

    Hi folks, I am trying to get DotNetOpenAuth's DesktopConsumer to work with Google, with not much success actually...

  • ASP.NET MVC Model Binding

    - by Noel
    If i have a Controller Action that may recieve both HTTP GET and HTTP POST from a number of different sources with each source sending different data e.g. Source1 performs a form POST with two form items Item1 and Item2 Source2 performs a GET where the data is contained in the query string (?ItemX=2&ItemY=3) Is it possible to have a controller action that will cater for all these cases and perform binding automatically e.g. public ActionResult Test(Dictionary data) { // Do work ... return View(); } Is this possible with a custom binder or some other way? Dont want to work directly with HttpContext.Request if possible

  • Linq guru - filtering related entities...

    - by vdh_ant
    My table structure is as follows: Person 1-M PesonAddress Person 1-M PesonPhone Person 1-M PesonEmail Person 1-M Contract Contract M-M Program Contract M-1 Organization At the end of this query I need a populated object graph where each person has their: PesonAddress's PesonPhone's PesonEmail's PesonPhone's Contract's - and this has its respective Program's Now I had the following query and I thought that it was working great, but it has a couple of problems: from people in ctx.People.Include("PersonAddress") .Include("PersonLandline") .Include("PersonMobile") .Include("PersonEmail") .Include("Contract") .Include("Contract.Program") where people.Contract.Any( contract => (param.OrganizationId == contract.OrganizationId) && contract.Program.Any( contractProgram => (param.ProgramId == contractProgram.ProgramId))) select people; The problem is that it filters the person to the criteria but not the Contracts or the Contract's Programs. It brings back all Contracts that each person has not just the ones that have an OrganizationId of x and the same goes for each of those Contract's Programs respectively. What I want is only the people that have at least one contract with an OrgId of x with and where that contract has a Program with the Id of y... and for the object graph that is returned to have only the contracts that match and programs within that contract that match. I kinda understand why its not working, but I don't know how to change it so it is working... This is my attempt thus far: from people in ctx.People.Include("PersonAddress") .Include("PersonLandline") .Include("PersonMobile") .Include("PersonEmail") .Include("Contract") .Include("Contract.Program") let currentContracts = from contract in people.Contract where (param.OrganizationId == contract.OrganizationId) select contract let currentContractPrograms = from contractProgram in currentContracts let temp = from x in contractProgram.Program where (param.ProgramId == contractProgram.ProgramId) select x where temp.Any() select temp where currentContracts.Any() && currentContractPrograms.Any() select new Person { PersonId = people.PersonId, FirstName = people.FirstName, ..., ...., MiddleName = people.MiddleName, Surname = people.Surname, ..., ...., Gender = people.Gender, DateOfBirth = people.DateOfBirth, ..., ...., Contract = currentContracts, ... }; //This doesn't work But this has several problems (where the Person type is an EF object): I am left to do the mapping by myself, which in this case there is quite a lot to map When ever I try to map a list to a property (i.e. Scholarship = currentScholarships) it says I can't because IEnumerable is trying to be cast to EntityCollection Include doesn't work Hence how do I get this to work. Keeping in mind that I am trying to do this as a compiled query so I think that means anonymous types are out.

    I the School class I have this code: from student in this.Students where student.Teacher.Id == id select student The Student class there are two relationships: Teacher and School. In the School class I'm trying to find out all the students whose Teacher has a given id. The problem is that I get System.NullReferenceException: Object reference not set to an instance of an object. in the statement student.Teacher.Id I thought of doing this.Students.Include("Teacher"), but this.Students doesn't have such a method. Any ideas how can I perform that query?

  • Adding existing entity to navigation property of a different entity

    - by Shay Friedman
    I'm using EF4 and I'm running into a problem when I try to do something that looks quite trivial to me. I have two entities, let's call them A and B. These entities have a many-to-many association between them with a navigation property on A that contains a list of related B entities. What I want to do is to add existing B entities to a new A entity. When I try to do that, I get an exception: AcceptChanges cannot continue because the object's key values conflict with another object in the ObjectStateManager. Make sure that the key values are unique before calling AcceptChanges. Has anyone run into such a problem?

  • 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

  • C++ Switch Statement Case Error

    - by Metal_Drummer
    I'm programming a simple text-based RPG using a switch statement for a game loop. The program works fine until I attempt to add another case statement, at which point it gives me the following three errors: "jump to case label" (error occurs at the line of the newly added case), and two "crosses initialization of 'ClassName *objectName'"(errors occur when the new objects are created in case 2). I'll paste the important code, if anyone needs more, please let me know. int main(void) { //initiate first object array and add some objects //initiate second object array and add some objects while(gamestate != 8) { switch(gamestate) { case 0: //do some stuff break; case 1: //do some stuff break; case 2: //declare new objects of the two... //...classes I have (ClassName *objectName) //do some stuff break; case 3: //this is the case I am trying to add //do nothing break; } } return 0; }

  • Proper way in Python to raise errors while setting variables

    - by ensnare
    What is the proper way to do error-checking in a class? Raising exceptions? Setting an instance variable dictionary "errors" that contains all the errors and returning it? Is it bad to print errors from a class? Do I have to return False if I'm raising an exception? Just want to make sure that I'm doing things right. Below is some sample code: @property def password(self): return self._password @password.setter def password(self,password): # Check that password has been completed try: # Check that password has a length of 6 characters if (len(password) < 6): raise NameError('Your password must be greater \ than 6 characters') except NameError: print 'Please choose a password' return False except TypeError: print 'Please choose a password' return False #Set the password self._password = password #Encrypt the password password_md5 = md5.new() password_md5.update(password) self._password_md5 = password_md5.hexdigest()

  • Basic XStream Annotations

    - by jmcmahon
    Hello, I just started using XStream Annotations, and I am trying to figure out how to associate the annotations with the XStream object. From the documentation, it seems like this is the accepted method: XStream xstream = new XStream(new DomDriver()); xstream.processAnnotations(AnnotatedClass.class); My problem with this is that Eclipse isn't recognizing this as a valid method. Everything seems to be configured correctly in Eclipse because it shows me the rest of the methods that are in the XStream object. It's almost like Eclipse thinks it's an older version of xstream. I've tried running a Project Clean inside of Eclipse but that didn't fix anything. I've also tried downloading the XStream jar again which didn't help either. Versions: XStream 1.3.1, Eclipse 3.4, Java 6 Has anybody seen this strange behavior before, or have any ideas on how to fix it?

  • Cast an NSDictionary value while applying an NSPredicate?

    - by RickiG
    Hi I have an Array of NSDictionary objects. These Dictionaries are parsed from a JSON file. All value objects in the NSDictionary are of type NSString, one key is called "distanceInMeters". I had planned on filtering these arrays using an NSPredicate, so I started out like this: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(distanceInMeters <= %f)", newValue]; NSArray *newArray = [oldArray filteredArrayUsingPredicate:predicate]; I believe this would have worked if the value for the "distanceInMeters" key was an NSNumber, but because I have it from a JSON file everything is NSStrings. The above gives this error:* -[NSCFNumber length]: unrecognized selector sent to instance 0x3936f00** Which makes sense as I had just tried to treat an NSString as an NSNumber. Is there a way to cast the values from the dictionary while they are being filtered, or maybe a completely different way of getting around this? Hope someone can help me :)

  • Change Sprite Anchorpoint without moving it?

    - by Oscar Gomez
    I am trying to change my Sprite anchor point so that I can rotate over a 0.0f,0.0f anchorpoint. At first my object is rotation at the default anchor point (0.5f,0.5f). However later on I need it to rotate over a 0.0,0.0 AnchorPoint. The problem is I cannot change the anchor point and change the position accordingly, so it stays on the same position, without the object appearing to quickly move and reposition to its original point. Is there a way I can set the anchor point and the position of my Sprite at once, without it moving at all?. Thank you. -Oscar

  • Stringtemplate: is it ok to Apply Templates, in which HashMap uses, To Multi-Valued Attributes

    - by user1071830
    There is two template in my .stg file, and both of them apply on multi-value a HashMap. The HashMap is employed as an injected object. And I need those instance of HashMap can be injected for many times. My trouble is, when I switch to another template, ANTLR seems to consider the second HashMap as a List -- multipul objects and null value. Part of my .stg file shows as follows: tpl_hash(BAR, FOO) ::= << <FOO:foo(); separator="\n"> <BAR:bar(); separator="\n"> >> foo(nn) ::= << foo: <nn.name; null="NULL"> . <nn.national; null="NULL"> >> bar(mm) ::= << bar: <mm.name> @ <mm.national> >> Part of my .g file shows: HashMap hm = new HashMap(); hm.put("name", $name.text); hm.put("national", "German"); tpl_hash.add("FOO",new HashMap(hm)); HashMap hm2 = new HashMap(); hm2.put("name", $name.text); hm2.put("national", "German"); tpl_hash.add("BAR",new HashMap(hm2)); The result I expect is : bar: Kant @ German foo: Russell @ England But, I got: foo: NULL . NULL foo: NULL . NULL bar: @ bar: @ If we replace BAR with FOO, as is, keeping FOO and BAR with identical template, the output is right, like the following. bar: Russell @ German bar: Russell @ German In docs, "synchronized ST add (String name, Object value) in org.stringtemplate.v4.ST" said: "If you send in a List and then inject a single value element, add() copies original list and adds the new value." What about a HashMap? Does ANTLR consider the HashMap, key/value pair access, an object purposely, as a List and as multi-value injected by mistake? Thanks a lot in advance.

  • IDataServiceMetadataProvider / ResourceType.... what for dynamic types with no CLR type?

    - by TomTom
    Hello, I try to expose a database via ADO RIA for which we have only an ODBC based interface. The "database" is a server and new elements are developped all the time, so I would like the server to check metadata at start (using the odbc schema methods) and then expose what he finds via RIA services.... clients can the nregenerate when they need access to new elements. As such, I dont ahve any CLR types for all the tabled developped. ResourceType tableType = new ResourceType( typeof(object), ResourceTypeKind.EntityType, null, "Martini", table_name, false ); tableType.CanReflectOnInstanceType = false; I can somehow not put in NULl as CLR element type, and entering typeof(object) seems to result in reflection errors when trying to access the properties. Any documentation on how to do that? I dont really want to get into having types... though if I have to, I probably will dynamically generate some via bytecode emit.

  • Custom validator not invoked when using Validation Application Block through configuration

    - by Chris
    I have set up a ruleset in my configuration file which has two validators, one of which is a built-in NotNullValidator, the other of which is a custom validator. The problem is that I see the NotNullValidator hit, but not my custom validator. The custom validator is being used to validate an Entity Framework entity object. I have used the debugger to confirm the NotNull is hit (I forced a failure condition so I saw it set an invalid result), but it never steps into the custom one. I am using MVC as the web app, so I defined the ruleset in a config file at that layer, but my custom validator is defined in another project. However, I wouldn't have thought that to be a problem because when I use the Enterprise Library Configuration tool inside Visual Studio 2008 it is able to set the type properly for the custom validator. As well, I believe the custom validator is fine as it builds ok, and the config tool can reference it properly. Does anybody have any ideas what the problem could be, or even what to do/try to debug further? Here is a stripped down version of my custom validator: [ConfigurationElementType(typeof(CustomValidatorData))] public sealed class UserAccountValidator : Validator { public UserAccountValidator(NameValueCollection attributes) : base(string.Empty, "User Account") { } protected override string DefaultMessageTemplate { get { throw new NotImplementedException(); } } protected override void DoValidate(object objectToValidate, object currentTarget, string key, ValidationResults results) { if (!currentTarget.GetType().Equals(typeof(UserAccount))) { throw new Exception(); } UserAccount userAccountToValidate = (UserAccount)currentTarget; // snipped code ... this.LogValidationResult(results, "The User Account is invalid", currentTarget, key); } } Here is the XML of my ruleset in Validation.config (the NotNull rule is only there to force a failure so I could see it getting hit, and it does): <validation> <type defaultRuleset="default" assemblyName="MyProj.Entities, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="MyProj.Entities.UserAccount"> <ruleset name="default"> <properties> <property name="HashedPassword"> <validator negated="true" messageTemplate="" messageTemplateResourceName="" messageTemplateResourceType="" tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.NotNullValidator, Microsoft.Practices.EnterpriseLibrary.Validation, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Not Null Validator" /> </property> <property name="Property"> <validator messageTemplate="" messageTemplateResourceName="" messageTemplateResourceType="" tag="" type="MyProj.Entities.UserAccountValidator, MyProj.Entities, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="Custom Validator" /> </property> </properties> </ruleset> </type> </validation> And here is the stripped down version of the way I invoke the validation: var type = entity.GetType() var validator = ValidationFactory.CreateValidator(type, "default", new FileConfigurationSource("Validation.config")) var results = validator.Validate(entity) Any advice would be much appreciated! Thanks, Chris

  • How to remove objects from an Enumerable collection in a loop

    - by johnc
    Duplicate Modifying A Collection While Iterating Through It Has anyone a nice pattern to allow me to get around the inability to remove objects while I loop through an enumerable collection (eg, an IList or KeyValuePairs in a dictionary) For example, the following fails, as it modifies the List being enumerated over during the foreach foreach (MyObject myObject in MyListOfMyObjects) { if (condition) MyListOfMyObjects.Remove(myObject); } In the past I have used two methods. I have replaced the foreach with a reversed for loop (so as not to change the any indexes I am looping over if I remove an object). I have also tried storing a new collection of objects to remove within to loop, then looping through that collection and removed the objects from the original collection. These work fine, but neither feels nice, and I was wondering if anyone has come up with a more elegant solution to the issue

    Is it possible to use Symbol MC70 series scanner with native code? I have a Windows Mobile application written using Lazarus(Object pascal) and I want to use it with Symbol MC70. The sdk that they have are for C, .NET and Java. I had a look at the C sdk and it comes with .LIB files which I cannot use with Object Pascal. I have no clue as to how the scanner is working with .NET stuff, I could not see a WIN32 dll in the files provided, maybe it is in the cab file. Any suggestions as to what I should do to get the scanners to work for me. Sandeep
