  • ASP.NET MVC & Windsor.Castle: working with HttpContext-dependent services

    - by Igor Brejc
    I have several dependency injection services which are dependent on stuff like HTTP context. Right now I'm configuring them as singletons the Windsor container in the Application_Start handler, which is obviously a problem for such services. What is the best way to handle this? I'm considering making them transient and then releasing them after each HTTP request. But what is the best way/place to inject the HTTP context into them? Controller factory or somewhere else?

  • Is it possible to call the main(String[] args) after catching an exception?

    - by Jason
    I'm working on a Serpinski triangle program that asks the user for the levels of triangles to draw. In the interests of idiot-proofing my program, I put this in: Scanner input= new Scanner(System.in); System.out.println(msg); try { level= input.nextInt(); } catch (Exception e) { System.out.print(warning); //restart main method } Is it possible, if the user punches in a letter or symbol, to restart the main method after the exception has been caught?

  • how to close a child browser in c# or WatiN?

    - by user177060
    I want to close the child window which is of "Browser" type. Have a look at the below code. WatiN.Core.Browser openBrowser = BrowserType.getBrowserObject().attachChildBrowser(document_name + Constants.open_document_title); I want to close the "openBrowser". Close()(available in WatiN) can only be used for the type "IE" of "Firefox" only. So, I cant use Close() method also. Is there any method to close the browser in C# or WatiN?

  • Webservice to add users to SharePoint (like SPWeb.EnsureUser)

    - by kpinhack
    Hallo, i need to add a user to a SharePoint-Website (WSS 3.0) via a Web Service. Using the API i would use the SPWeb.EnsureUser method, but i can't run my own code on the server. I was hoping the Users and Groups Web Service could help, but it does not provide a suitable method. So, is there a Web Service equivalent to SPWeb.EnsureUser? Thanks!

  • What is the cost of object creating.

    - by Tony
    Hi If I have to choose between static method and creating an instance and use instance method, I will choose static methods always. but what is the detailed overhead of creating an instance? for example I saw a DAL which can be done with static classes but they choose to make it instance now in the BLL at every single call they call something like. new Customer().GetData(); how far this can be bad? Thanks

  • How can the AssemblyName class be used for existing Assemblies?

    - by IbrarMumtaz
    This is another exam related question. I want to know how can I use the AssemblyName class to represent an existing assembly that already exists on disk??? I am talking about from the perspective of using the AppDomain's instance method .Load(), that takes an AssemblyName object as a parameter. I know what MSDN has to say about what the .Load() method was designed for but that aside, I still want to know how to use it !!!

  • hashing password giving different results

    - by geoff
    I am taking over a system that a previous developer wrote. The system has an administrator approve a user account and when they do that the system uses the following method to hash a password and save it to the database. It sends the unhashed password to the user. When the user logs in the system uses the exact same method to hash what the user enters and compares it to the database value. We've run into a couple of times when the database entry doesn't match the user's entry whey they should. So it appears that the method isn't always hashing the value the same. Does anyone know if this method of hashing isn't reliable and how to make it reliable? Thanks. private string HashPassword(string password) { string hashedPassword = string.Empty; // Convert plain text into a byte array. byte[] plainTextBytes = Encoding.UTF8.GetBytes(password); // Allocate array, which will hold plain text and salt. byte[] plainTextWithSaltBytes = new byte[plainTextBytes.Length + SALT.Length]; // Copy plain text bytes into resulting array. for(int i = 0; i < plainTextBytes.Length; i++) plainTextWithSaltBytes[i] = plainTextBytes[i]; // Append salt bytes to the resulting array. for(int i = 0; i < SALT.Length; i++) plainTextWithSaltBytes[plainTextBytes.Length + i] = SALT[i]; // Because we support multiple hashing algorithms, we must define // hash object as a common (abstract) base class. We will specify the // actual hashing algorithm class later during object creation. HashAlgorithm hash = new SHA256Managed(); // Compute hash value of our plain text with appended salt. byte[] hashBytes = hash.ComputeHash(plainTextWithSaltBytes); // Create array which will hold hash and original salt bytes. byte[] hashWithSaltBytes = new byte[hashBytes.Length + SALT.Length]; // Copy hash bytes into resulting array. for(int i = 0; i < hashBytes.Length; i++) hashWithSaltBytes[i] = hashBytes[i]; // Append salt bytes to the result. for(int i = 0; i < SALT.Length; i++) hashWithSaltBytes[hashBytes.Length + i] = SALT[i]; // Convert result into a base64-encoded string. hashedPassword = Convert.ToBase64String(hashWithSaltBytes); return hashedPassword; }

  • calling a dynamic function in javascript

    is it possible to call a dynamic method in javascript. ie suppose i have in my page 2 methods as such: function id1_add() { return 1; } function id2_add() { return 2; } i also have this function: function add() { var s1='id1'; s1+'_add()'; //??? } is it possible to call for example id1_add() in such: s1+'_add()'; so the method call depends on a previous string?

  • Creating and Saving an Excel File

    - by Kris
    I have the following code that creates a new Excel file in my C# code behind. When I attempt to save the file I would like the user to select the location of the save. In Method #1, I can save the file my using the workbook SaveCopyAs without prompting the user for a location. This saves one file to the C:\Temp directory. Method #2 will save the file in my Users\Documents folder, then prompt the user to select the location and save a second copy. How can I eliminate the first copy from saving in the Users\Documents folder? Excel.Application oXL; Excel._Workbook oWB; Excel._Worksheet oSheet; Excel.Range oRng; try { //Start Excel and get Application object. oXL = new Excel.Application(); oXL.Visible = false; //Get a new workbook. oWB = (Excel._Workbook)(oXL.Workbooks.Add(Missing.Value)); oSheet = (Excel._Worksheet)oWB.ActiveSheet; // ***** oSheet.Cells[2, 6] = "Ship To:"; oSheet.get_Range("F2", "F2").Font.Bold = true; oSheet.Cells[2, 7] = sShipToName; oSheet.Cells[3, 7] = sAddress; oSheet.Cells[4, 7] = sCityStateZip; oSheet.Cells[5, 7] = sContactName; oSheet.Cells[6, 7] = sContactPhone; oSheet.Cells[9, 1] = "Shipment No:"; oSheet.get_Range("A9", "A9").Font.Bold = true; oSheet.Cells[9, 2] = sJobNumber; oSheet.Cells[9, 6] = "Courier:"; oSheet.get_Range("F9", "F9").Font.Bold = true; oSheet.Cells[9, 7] = sCarrierName; oSheet.Cells[11, 1] = "Requested Delivery Date:"; oSheet.get_Range("A11", "A11").Font.Bold = true; oSheet.Cells[11, 2] = sRequestDeliveryDate; oSheet.Cells[11, 6] = "Courier Acct No:"; oSheet.get_Range("F11", "F11").Font.Bold = true; oSheet.Cells[11, 7] = sCarrierAcctNum; // ***** Method #1 //oWB.SaveCopyAs(@"C:\Temp\" + sJobNumber +".xls"); Method #2 oXL.SaveWorkspace(sJobNumber + ".xls"); } catch (Exception theException) { String errorMessage; errorMessage = "Error: "; errorMessage = String.Concat(errorMessage, theException.Message); errorMessage = String.Concat(errorMessage, " Line: "); errorMessage = String.Concat(errorMessage, theException.Source); }

  • [ruby] Check if file is a valid image

    - by some guy
    Hi all, I'm using rmagick to manipulate image files. I use the ImageList.new on each file to get started. When I apply this method to an invalid image file I get the below error which interrupts the execution of the script: RMagick.rb:1635:in `read': Improper image header (Magick::ImageMagickError) Therefore I would like to be able to check whether a file is a valid image file before using this method. Any ideas? Thanks.

  • Get column name in jpa

    - by German
    Hi all, I have a query factory that takes a column name as an attribute in order to search for that column. Right now I'm passing the name of the column as a string, so it's kind of hardcoded. If the name of the column changes in the entity's annotation, that "hidden dependency" breaks up. Is there a way in jpa to retrieve the real name of the column and have it available at compile time, so I can use it in queries?

  • Web Services, Memory Leaks and CRM

    - by Neil
    Hi, I have a website that allows users to upload a csv file. This calls a service that reads the information from the csv, puts it into DynamicEntity objects and calls the CRM service to Create/Update entities in CRM. When this service creates/updates an entity this kicks off other plugins to apply certain business rules. These rules can also Create or Update entites in CRM. The issue here is that the handle count of the w3wp.exe process that the website is calling increases every time the an entity is created or updated and it never comes back down. I tried putting Garbage Collection code in the business rules and this reduces the handle count of the CRM w3wp process (run by the Network Service), but not the other w3wp process. Should I have Dispose methods on the Web Service that calls the CRM service? I hope that makes sense. I'm not overly familiar with memory management issues so any help is appreciated. Can anybody give me some tips on how to stop this from occurring? Thanks, Neil -- EDIT Okay well the handle count goes up when I call the Service.Create(DynamicEntity) method. I don't think placing any code here would be beneficial. When I exit the method/class/service that contains this call the handle count stays as it is. What I need to know is whether this is something I should be managing or is it something CRM takes care of (or doesn't take care of but I can't do anything about it) -- Another Edit Right this is how it works. 1) We have CRM and its related services 2) We have another service independent of CRM that uses the CRM services (number 1 above) to create entities based on csv info passed into it 3) We have a website that allows a user to upload a csv, and calls service no 2 above to Create/Update entities in CRM 4) We have plugins fired by CRM which use Service 1 above to create/update entities So the user uploads a csv to the website (3), this fires a service(2). When service 2 creates an entity using service 1, Service 4 fires. Service 4 calls also uses service 1 to Create entities, and when these services are called (using the Service.Create() method) the handle count of the process increases. When the method/class/services finish the handle count remains the same, and so when the whole process occurs again the handle count will increased again.

  • [C++] STL list - how to find a list element by its object fields

    - by Dominic Bou-Samra
    I have a list: list<Unit *> UnitCollection; containing Unit objects, which has an accessor like: bool Unit::isUnit(string uCode) { if(this->unitCode == uCode) return true; else return false; } How do I search my UnitCollection list by uCode and return the corresponding element (preferably it's index). I have looked at the find() method, but i'm not sure you can pass a boolean method in instead of a searched item parameter if that makes sense.

  • Collision Detection for arbitrarily sized, positioned and rotated rectangles in XNA

    - by Stefan
    I'm working with xna in C# and in my game I will have a variety of space ships flying all over the place. They will each have an arbitrary rotation, size and position in space and I need a method to determine when they collide. Ideally the method would take two Rectangles, two doubles and two Vector2s for size, rotation and position respectively and return a boolean that indicates whether they have intersected or not.
