  • How to open connection to local network path protected by password in smart way? (Whith C#)

    - by lfx
    Hi, I developing program witch have to write some data in file whom are stored in network computer witch are protected by password. Now I'm doing this way - open connection with cmd then write data. static bool ConnectToSrv() { String myUser = "domain.local\\user"; String myPass = "pwd"; String cmdString = "net use \\\\otherPC\\folder\\ /user:" + myUser + " " + myPass; try { ManagementClass processClass = new ManagementClass("Win32_Process"); object[] methodArgs = { cmdString, null, null, 0 }; object result = processClass.InvokeMethod("Create", methodArgs); return true; } catch (System.Exception error) { return false; } } public void writeDate(string data){ } I believe there must by better way. I mean the .NET way. Does anybody know how to do it? :) Thanks

  • html5media & flowplayer wmode issues...

    - by minusidea
    I'm working on our new homepage and need to implement a solution that will run a video across iphone/ipad and the standard web browsers. I found a pretty decent solution with html5media - http://code.google.com/p/html5media/ but ran across an issue with a jquery dropdown falling behind the the swf object (this only happens on FF & IE - works fine on Safari & Chrome because it's loading mp4 instead of a swf object). I know the issue is the wmode setting but can not for the life of me figure out where to set it in the html5media (http://html5media.googlecode.com/svn/trunk/src/html5media.min.js). I'm hoping someone can help me or possibly give me a better solution of implementing the video. You can see the development page at idssite(dot)com/development/index.php - Sorry I can't link I'm being stopped by the spam prevention mechanism. Thanks

  • Empty dict-like collection problem in SQLAlchemy

    - by maksymko
    I have a mapping in SQLAlchemy that looks like this: t_property_value = sa.Table('property_value', MetaData, autoload = True, autoload_with = engine) orm.mapper(PropertyValue, t_property_value) t_estate = sa.Table('estate', MetaData, autoload = True, autoload_with = engine) orm.mapper(Estate, t_estate, properties = dict( property_hash = orm.relation(PropertyValue, collection_class = column_mapped_collection(t_property_value.c.property_id)) )) Now, everything seems to be fine, when I load the Estate object and it has some relations to PropertyValue objects. However, when it does not, then property_hash attribute is None, instead of being something dict-like, so I can not add new relations like this: estate.property_hash[prop_id] = PropertyValue(...) because I get the "'NoneType' object does not support item assignment" error. So, is there any way to force SQLAlchemy to create proper empty collection?

  • Core Data produces Analyzer warnings

    - by RickiG
    Hi I am doing the final touch ups on an app and I am getting rid of every compiler/analyzer warning. I have a bunch of Class methods that wrap my apps access to Core Data entities. This is "provoking" the analyzer. + (CDProductEntity*) newProductEntity { return (CDProductEntity*)[NSEntityDescription insertNewObjectForEntityForName:@"CDProductEntity" inManagedObjectContext:[self context]]; } Which results in an Analyzer warning: Object with +0 retain counts returned to caller where a +1 (owning) retain count is expected In the method that calls the above Class Method I have this: CDProductEntity *newEntity = [self newProductEntity]; Which results in an Analyzer warning: Method returns an Objective-C object with a +1 retain count (owning reference) Explicitly releasing or autoreleasing a Core Data entity is usually very very bad, but is that what it is asking me to do here? First it tells me it has a +0 retain count and that is bad, then it tells me it has a +1 which is also bad. What can I do to ensure that I am either dealing with a Analyzer hiccup or that I release correctly? Thanks in advance

  • Id property not populated

    - by fingers
    I have an identity mapping like so: Id(x => x.GuidId).Column("GuidId") .GeneratedBy.GuidComb().UnsavedValue(Guid.Empty); When I retrieve an object from the database, the GuidId property of my object is Guid.Empty, not the actual Guid (the property in the class is of type System.Guid). However, all of the other properties in the object are populated just fine. The database field's data type (SQL Server 2005) is uniqueidentifier, and marked as RowGuid. The application that is connecting to the database is a VB.NET Web Site project (not a "Web Application" or "MVC Web Application" - just a regular "Web Site" project). I open the NHibernate session through a custom HttpModule. Here is the HttpModule: public class NHibernateModule : System.Web.IHttpModule { public static ISessionFactory SessionFactory; public static ISession Session; private static FluentConfiguration Configuration; static NHibernateModule() { if (Configuration == null) { string connectionString = cfg.ConfigurationManager.ConnectionStrings["myDatabase"].ConnectionString; Configuration = Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005.ConnectionString(cs => cs.Is(connectionString))) .ExposeConfiguration(c => c.Properties.Add("current_session_context_class", "web")) .Mappings(x => x.FluentMappings.AddFromAssemblyOf<LeadMap>().ExportTo("C:\\Mappings")); } SessionFactory = Configuration.BuildSessionFactory(); } public void Init(HttpApplication context) { context.BeginRequest += delegate { Session = SessionFactory.OpenSession(); CurrentSessionContext.Bind(Session); }; context.EndRequest += delegate { CurrentSessionContext.Unbind(SessionFactory); }; } public void Dispose() { Session.Dispose(); } } The strangest part of all, is that from my unit test project, the GuidId property is returned as I would expect. I even rigged it to go for the exact row in the exact database as the web site was hitting. The only differences I can think of between the two projects are The unit test project is in C# Something with the way the session is managed between the HttpModule and my unit tests The configuration for the unit tests is as follows: Fluently.Configure() .Database(MsSqlConfiguration.MsSql2005.ConnectionString(cs => cs.Is(connectionString))) .Mappings(x => x.FluentMappings.AddFromAssemblyOf<LeadDetailMap>()); I am fresh out of ideas. Any help would be greatly appreciated. Thanks

  • Can anyone recommend a .Net XML Serialization library?

    - by James
    Can anyone recommend a .Net XML Serialization library (ideally open source). I am looking for a robust XML serialization library that I can throw any object at, which will produce a human readable XML representation of the public properties for logging purposes. I never need to be able to deserialize. XmlSerializer's requirement of an object having a parameter constructor is too restrictive for what I want. DataContractSerializer does not give enough control over the output (which is not particularly human-readable). Any recommendations appreciated! Thanks

    Hi, I'm doing a Facebook App where I'd like to pull out all the possible images from a user's album. What I'm trying to do at the moment is a fql query so that i can find all the images that belong to that specific user. it goes something like that: protected function loadFromFacebook(event:MouseEvent):void { var fql:String = "select src_small from photo where owner = me()"; Facebook.fqlQuery(fql, handleGetPhotosResponse); } private function handleGetPhotosResponse(event:Object, fail:Object):void { if (event != null){ facebookPhotos = new ArrayCollection(event as Array); } } I store this images in an array collection but I don't know how to proceed after that. How can I load those images into, say, a Tile List or a Loader? Any help would be much appreciated, thanks

  • Connection Pooling

    - by cshah
    I have the following code, If I use conn == null in finally do I still use connection pooling? I know it is a good practice to close your connection but how about disposing the whole connection object? public void ExecuteNonQuery(SqlCommand Cmd) { //========== Connection ==========// SqlConnection Conn = new SqlConnection(strConStr); try { //========== Open Connection ==========// Conn.Open(); //========== Execute Command ==========// Cmd.Connection = Conn; Cmd.CommandTimeout = 180; Cmd.ExecuteNonQuery(); } catch (Exception Exc) { throw Exc; } finally { //======== Closing Connection ========// if (Conn.State == ConnectionState.Open) { Conn.Close(); } //======== Disposing object ========// Conn = null; } }

  • Treating a fat webservice in .net 3.5 c#

    - by Chris M
    I'm dealing with an obese 3rd party webservice that returns about 3mb of data for a simple search results, about 50% of the data in that response is junk. Would it make sense then to remap this data to my own result object and ditch the response so I'm storing 1-2 mb in memory for filtering and sorting rather than using the web-responses own object and using 2-4 or am I missing a point? So far I've been accessing the webservice from a separate project and using a new class to provide the interaction and to handle the persistence so my project looks like this |- Web (mvc2 proj) |- DAL (database/storage fluent-nhibernate) |- SVCGateway (interaction layer + webservice related models) |- Services -------------- |- Tests |- Specs I'm trying to make the application behave fast and I also need to store the result set temporarily in case a customer goes to view the product and wants to go back to the results. (Service returns only 500 of possible 14K results). So basically I'm looking for confirmation that I'm doing the right thing in pushing the results into my own objects or if I'm breaking some rule or even if there's a better way of handling it. Thanks

  • Do we really need a safe release macro?

    - by Ian1971
    Quite a lot of people seem to use a macro such as #define SAFE_RELEASE(X) [X release]; X = nil; (myself included). I've been reassessing why I am using it and wanted to canvas some opinion. The purpose (I think) for using this macro is so that if you were to accidentally use your object after releasing it then you won't get a bad access exception because objective-c will quite happily ignore it when the object is nil. It strikes me that this has the potential to mask some obscure bugs. Maybe it would actually be preferable for the program to crash when you try to use X again. That way during testing you can find the issue and improve the code. Does this macro encourage lazy programming? Thoughts?

  • How to make Event visible?

    - by eflles
    Inside a Silverlight library project I have a public event, which is not visible for other classes. How can I make the event visible?

  • Getting Http Status code number (200, 301, 404, etc.) from HttpWebRequest and HttpWebResponse

    - by James Lawruk
    I am trying to get the HTTP status code number from the HttpWebResponse object returned from a HttpWebRequest. I was hoping to get the actual numbers (200, 301,302, 404, etc.) rather than the text description. ("Ok", "MovedPermanently", etc.) Is the number buried in a property somewhere in the response object? Any ideas other than creating a big switch function? Thanks. HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://www.gooogle.com/"); webRequest.AllowAutoRedirect = false; HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse(); //Returns "MovedPermanently", not 301 which is what I want. Console.Write(response.StatusCode.ToString());

  • Model of hql query firing at back end by hql engine?

    - by Maddy.Shik
    I want to understand how hibernate execute hql query internally or in other models how hql query engine works. Please suggest some good links for same? One of reason for reading is following problem. Class Branch { //lazy loaded @joincolumn(name="company_id") Company company; } Since company is heavy object so it is lazy loaded. now i have hql query "from Branch as branch where branch.Company.id=:companyId" my concern is that if for firing above query, hql engine has to retrieve company object then its a performance hit and i would prefer to add one more property in Branch class i.e. companyId. So in this case hql query would be "from Branch as branch where branch.companyId=:companyId" If hql engine first generate sql from hql followed by firing of sql query itself, then there should be no performance issue. Please let me know if problem is not understandable.

  • WSAT Security tab error for Custom Role provider

    - by shesb
    I have created custome Membership Role and Profile provider using INGRES db. Now I can see my IngresMembership and IngresRole provider in the Provider tab(Select a different provider for each feature (advanced) ) of WSAT but when I clik on security tab I get this error: "There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store. The following message may help in diagnosing the problem: Object reference not set to an instance of an object." What am I missing? Do I need to add code for all override methods for Role provider? I have just written code for the Initialize and GetRolesForUser functions. Thanks

  • C++ memory management of reference types

    - by Russel
    Hello, I'm still a fairly novice programmer and I have a question about c++ memory management with refence types. First of all, my understanding of reference types: A pointer is put on the stack and the actual data that the pointer points to is created and placed on the heap. Standard arrays and user defined classes are refence types. Is this correct? Second, my main question is do c and c++'s memory management mechanisms (malloc, free and new, delete) always handle this properly and free the memory that a class or array is pointing to? Does everything still work if those pointers get reassigned somehow to other objects of the same size/type on the heap? What if a class has a pointer member that points to another object? I am assuming that delete/freeing the class object doesn't free what it's member pointer points to, is that correct? Thanks all! -R

  • Axis xsd:dateTime issue

    - by milostrivun
    Here is the whole thing. I 'm using a webservice, with wsdl2java I generate classes and communicate with another application. Problem is , when I use a method from my generated WS client that is resulting in data that contains some object with data in format xsd:dateTime(Axis 1.4), and that data is represensted by java.util.Calendar object in java has time shifted to GMT(about two hours before my time zone). That results in bad data that I have to substract two hours to display correct value. My question is, considering I didn't work on building that webservice(all I have is wsdl url) where is the problem and can I fix it or the problem is at the side of the webservice creator. If I'm it is not clear what I am asking I will gladly explain as much as I can.

  • Mono 2.10.5 Runtime error on Ubuntu 11.10

    - by johnluetke
    I've install mono-runtime via apt in order to run my Mono console application on Ubuntu via SSH. However, when I run the command mono myapp.exe, It exits, with no message, and my program does nothing. If I throw the -v switch to Mono, such as mono -v myapp.exe, I get about 10k lines of output (as expected, -v is verbose), with the first few lines being: converting method System.OutOfMemoryException:.ctor (string) Method System.OutOfMemoryException:.ctor (string) emitted at 0xb7052c28 to 0xb7052c4b (code length 35) [myapp.exe] converting method (wrapper runtime-invoke) <Module>:runtime_invoke_void__this___object (object,intptr,intptr,intptr) Method (wrapper runtime-invoke) <Module>:runtime_invoke_void__this___object (object,intptr,intptr,intptr) emitted at 0xb7052c68 to 0xb7052cf6 (code length 142) [myapp.exe] converting method System.SystemException:.ctor (string) I read this as the runtime throwing an OutOfMemory exception, but the machine is under no intense load, has plenty of available RAM, and is running nothing other that system processes. I've removed and reinstalled Mono countless times, and have even run the executable on other machines perfectly fine. Am I missing something completely obvious here?

  • Removing items from lists and all references to them.

    - by LiamV
    I'm facing a situation where I have dependent objects and I would like to be able to remove an object and all references to it. Say I have an object structure like the code below, with a Branch type which references two Nodes. public class Node { // Has Some Data! } public class Branch { // Contains references to Nodes public Node NodeA public Node NodeB } public class Graph { public List<Node> Nodes; public List<Branch> Branches; } If I remove a Node from the Nodes list in the Graph class, it is still possible that one or more Branch objects still contains a reference to the removed Node, thus retaining it in memory, whereas really what I would quite like would be to set any references to the removed Node to null and let the garbage collection kick in. Other than enumerating through each Branch and checking each Node reference sequentially, are there any smart ideas on how I remove references to the Node in each Branch instance AND indeed any other class which reference the removed Node?

  • How do I extend a WPF application using an addin-like architeture?

    - by Thiado de Arruda
    Lets say I have a WPF application that shows a ListBox with an ArrayList -populated with objects of arbitrary types- as a source, and this application is hosted in an assembly 'A'. By default the ListBox will display the custom object 'ToString' method return value. If a data template for that object type is found, the ListBox will use it for rendering. Imagine that theres another assembly 'B' that references of 'A' and seeks to extend it by providing custom data templates for certain types, to be used in that ListBox. Is there some way to do that without 'A'being aware of B?

  • Working with Multiple Layers - KineticJS

    - by Bruno Sampaio
    I'm using KineticJS 4.0.5 and I'm currently trying to draw the contents of several layers but only the last one added to stage is drawn... If I understood the documentation correctly this should be possible, otherwise why would we need a layer? I have three different layers: a background layer with just a Kinectic.Rect object; a elements layer with several types of shapes; and a top layer with elements I want to be always on top of everything. I populate those layers inside a draw function I have inside a object I created, this object also has a shape attribute which refers to the background and a contents attribute with the elements to add to the elements layer. My code for the draw function is the following: this.draw = function() { var stage = E.game.stage, layers = E.game.layers; stage.clear(); // Add Background this.shape.setSize(stage.getWidth(), stage.getHeight()); layers.background.add(this.shape); // Iterate over contents for(var i = 0; i < this.contents.length; i++) { layers.elements.add(this.contents[i].shape); } // Draw Everything stage.add(layers.background); stage.add(layers.elements); stage.add(layers.top); // This one is currently empty stage.draw(); } After running this function, only layers.top is drawn in the canvas, and if I comment the line where it is added only layers.elements is drawn. However the stage has 3 childrens (I checked it with inspect element on chrome) and in the documentation it says the draw function draws all layers... Am I doing something wrong here? Or it isn't possible? And if it's not possible why would I need a layer and a stage? Wouldn't one be enough? Thank you in advance. Edit: I was able to solve the problem, I was applying a white background color with css to the canvas element and since each layer creates a new canvas element above the others I could only see the contents for the top most layer (in this case just white). However, I still have a problem related with multiple layers that I didn't have before with just one layer. When I use the clear function on the stage it should clear the layers right? But instead the layers remain exactly the same, even if I try to call clear on each individual layer they won't change... I'm also using the stage draw function after clearing them but still no changes at all... The only solution I found until now was by removing the layer from the stage and adding it again :s Is there a better way to reset the layers contents? Thank you again and sorry for the confusion with the first question.

  • Elegant way to reverse order Formtastic nested objects?

    - by stephan.com
    I'm presenting a list of items to the user with a field for a new item, like this: - current_user.tasks.build - semantic_form_for current_user do |f| - f.semantic_fields_for :tasks do |t| - t.inputs do = t.input :_destroy, :as => :boolean, :label => '' - if t.object.new_record? = t.input :name, :label => false - else = t.object.name Which looks lovely and works like a charm. My only problem is I want the new record at the TOP of the list, not the bottom. Is there an elegant and easy way to do this, or am I going to have to do the new element separately, or loop through the list manually?
