  • .Net: Prevent an object from being paged out (VirtualLock equivalent)

    - by Gene
    How would one go about keep an object in memory such that it won't be paged out by the OS in .Net? i.e. Something similar to VirtualLock, but operating on an object, such that if compacting occurs and the object is moved it still would not be paged out, etc.. (I suppose one could pin the object's, determine what pages it belongs to, and then VirtualLock those pages, but that seems non-desireable for many reasons.) If possible, could you point me to a reference or working sample? (C# ideally) Many thanks in advance!

  • Response.Redirect in a COM+ Object Called from Classic ASP Page

    - by ajdams
    Basically we moved from IIS 5 to IIS 7 and I am trying to update some of our old COM objects to .NET by rewriting them in C#. What I am have so far is a Classic ASP page calling the COM+ object and then I am trying to do a simple redirect within the COM+ object (this is just for testing purposes, it's not what the object will do eventually). My problem/question is, why does the redirect call not work properly? Am I doing something wrong or can you not redirect within a COM+ object? All that happens is a blank white page comes up and if I check the IIS logs, I see no errors. Here is my code so far: In Classic ASP (the call to COM+) Set oBankReg = CreateObject("BVSRegistration.SignIn") oBankReg.GetBankId(bankid) Code in C# COM object: using System; using System.Web; using System.Text; using System.EnterpriseServices; using System.Collections.Generic; using System.Runtime.InteropServices; [assembly: ApplicationName("BVSRegistration")] [assembly: Description("COM+ upgrade of the BVSRegistration VB6 SignIn.cls.")] [assembly: ApplicationActivation(ActivationOption.Server)] [assembly: ApplicationAccessControl(false, AccessChecksLevel = AccessChecksLevelOption.ApplicationComponent)] namespace BVSRegistration { public class SignIn : ServicedComponent { public void GetBankId(string bankid) { HttpContext.Current.Response.Redirect("http://www.google.com"); } } } Any ideas? Thanks

  • What's a good pure-python, document-based and flat-file database engine?

    - by joe Simpson
    Hi, for development i'd love to have a flat file database with the requirements up in the title, but I don't seem to be able to find a database with these requirements. I can't seem to get MetaKit to work. I only need it to work on the development machine, but in the real world my product will have more data and needs more room and will need something better. Does anyone know of a database engine capable of this or do I need to just use python's pickle and load and save a file? Joe

  • Django: many-to-one fields and data integrity

    - by John
    Let's say that I have a Person who runs an inventory system. Each Person has some Cars, and each Car has a very large number of Parts (thousands, let's say). A Person, Bob, uses a Django form to create a Car. Now, Bob goes to create some Parts. It is only at the form level that Django knows that the Parts belong to some specific Car, and that the Parts.ForeignKey(Car) field should only have a specific Car as a choice. When creating a Part, you have to mess with the form's constructor or similar in order to limit the choice of Cars to only the cars owned by Bob. It does not seem proper that to enforce this ownership at the form level. It seems that other users' Cars must be inaccessible to anyone but the owner of the Car. What do you all think about this, and is there any way to enforce this?

  • Exclude rows with Doctrine ORM DQL (NOT IN)

    - by Sheriffen
    I'm building a chat application with codeigniter and doctrine. Tables: - User - User_roles - User_available Relations: ONE user have MANY roles. ONE user_available have ONE user. Users available for chatting will be in the user_available table. Problem: I need to get all users in in user_available that hasn't got role_id 7. So I need to express in DQL something like (this is not even SQL, just in words): SELECT * from user_available WHERE NOT user_available.User.Role.role_id = 7 Really stuck on this one EDIT: Guess I was unclear. The tables are already mapped and Doctrine does the INNER JOIN job for me. I'm using this code to get the admin that waited the longest but now I need the user: $admin = Doctrine_Query::create() ->select('c.id') ->from('Chat_available c') ->where('c.User.Roles.role_id = ?', 7) ->groupBy('c.id') ->orderBy('c.created_at ASC') ->fetchOne(); Now I need to get the user that waited the longest but this does NOT work $admin = Doctrine_Query::create() ->select('c.id') ->from('Chat_available c') ->where('c.User.Roles.role_id != ?', 7) ->groupBy('c.id') ->orderBy('c.created_at ASC') ->fetchOne();

  • Conditional relation

    - by Lowgain
    I've got a model like this: Stem -id -etc And then I have Stemrelation -stem_id -related_stem_id -active I can get the related stems with the following relations class Stem < ActiveRecord::Base has_many :stemrelations has_many :related_stems, :through => :stemrelations end class Stemrelation < ActiveRecord::Base belongs_to :stem belongs_to :related_stem, :class_name => "Stem", :foreign_key => "related_stem_id" end But now I'd only like to get the active relations. I tried adding this to the Stem model: has_many :active_related, :through => :stemrelations, :source => :related_stem, :conditions => {:active => true} but this gives me an error becasue it tries to check the active flag on the stem model instead of the stemrelation. What do I change here? Thanks!

  • Software to find dependencys in a database that not have them as restrictions

    - by Tomas Friden
    I have a database in SQL server 2005 that originaly comes fom an old mainframe. All relations was set in the surrounding software and there are non i the database. I need to find the relations, not by field name but by actual contence in the registers. (as suggestions, I realize I'l have to check them up) It would be nice with some extras, like finding motherless posts etc. but not a primary demand. There are some 200 registers with max 2 000 000 posts in any register. Does any one know of a software that can help me with this? The software I can find presuposes that relations are set in the database :(

  • ER Diagram flaws

    - by spacker_lechuck
    I have the following ER Diagram for a bank database - customers may have several accounts, accounts may be held jointly by several customers, and each customer is associated with an account set and accounts are members of one or more account sets. What design rules are violated? What modifications should be made and why? So far, a few flaws I'm not sure about are: 1) Redundant owner-address attribute in AcctSets Entity. 2) This ER does not include accounts with multiple owners with different addresses. My Question is: How would I go about fixing these flaws and/or other flaws that I may be missing from my analysis? Thanks!

  • Getting COM object to run in Vista

    - by rainslg
    We expose an interface to our simulation software using a COM/ActiveX object. This worked just fine in XP, but in Vista, we get "Error 429: ActiveX can't create object" when a VB client executes CreateObject(). The COM object has been registered by hand so that the Vista Registry is identical to XP's Registry. I run the VB interface from a DOS window that I started using "Run As Administrator". The client is correctly accessing and reading the Registry as I walk through using the debugger in VB, so it's apparently not a security setting, as near as I can tell. I have also loaded the files into VS2005 (the object was originally created in VS6) and rebuilt them to get a later ATL version, but that hasn't helped - we still get the 429 error. Is this a symptom of UAC problems, or should I be looking for something deeper?

  • SOA design principles with regards to database relationships

    - by Eitan
    If I were to extricate my current membership provider from my solution, i.e. as a dll and expose it as a web service with it's own db, how would I model the relationships with regards to SOA design. For example I have a table: USER id, name, lastname, username, password, role. and table PRODUCT id, name, price, createdate, userid the foreign key being userid to table user. How would I model the relationship and/or query the db. If I wanted to get all products that were uploaded today for example, before I would query: SELECT u.name, u.lastname, u.username, p.* FROM PRODUCT p INNER JOIN USER u ON p.userid = u.id WHERE createdate = '05/05/2010' Now that I don't have the table within the database how would I perform this query? Thanks.

  • ComDlg32.ocx Error: Object doesn't support this property or method

    - by abhilashca
    I'm developing an html editor using ComDlg32.ocx (Commom Dialog Control), using HTML and VBScript. My exact requirement was to prompt Open/Save/Color/Print/Font dialog boxes.Ive written code for prompting Save file dialog box. Also I've added a license file using LPK Tool onto my webpage. My html-source looks like: <body> <!-- lpk file --> <object classid="clsid:5220cb21-c88d-11cf-b347-00aa00a28331"> <param name="LPKPath" value="License/comdlg.lpk" /> </object> <!-- Microsoft Common Dialog Control --> <object classid="CLSID:F9043C85-F6F2-101A-A3C9-08002B2F49FB" codebase="http://activex.microsoft.com/controls/vb6/COMDLG32.CAB" id="objComDlg"></object> </body> Now, here comes my error. Whenever I try to call the vbscript for prompting the Save File dialog box, Im getting an error as : Object doesn't support this property or method: 'objComDlg.Filter' If I comment out the objComDlg.Filter then the error move on to objComDlg.DialogTitle and thus it goes on. And my VBScript look like: FILE_FORMATS = "Rich Text Format (*.rtf)|*.rtf|Microsoft Word (*.doc)|*.doc|ANSI Text Document (*.txt)|*.txt" objComDlg.Filter = FILE_FORMATS <--- Error shows here objComDlg.DialogTitle = "Save As " objComDlg.Flags = cdlOFNFileMustExist Or cdlOFNHideReadOnly objComDlg.CancelError = True objComDlg.ShowSave Does anyone have an idea why this is happening? Is there any proper documentation for using this particular ActiveX control? My current development is in stand-still due to this error. Any help will be appreciated. Looking forward for your response. BTW, I'm using Windows XP SP3 and IE8 for my development. Thanks.

  • Cast LINQ Function Result to Domain Object

    - by Alex
    Hello, I have a table valued function to perform full text search on SQL server. The result type of my full text search function in LINQ is a special autogenerated type which includes KEY and RANK in addition to my regular domain object properties. So, if my regular domain object is PERSONS (with properties FirstName, LastName etc.), I also have a result object PERSONS_FTSResult with the same properties + KEY and RANK. Is there an easy way to cast it back to PERSONS?

  • phpUnit - mock php extended exception object

    - by awongh
    I'm testing some legacy code that extends the default php exception object. This code prints out a custom HTML error message. I would like to mock this exception object in such a way that when the tested code generates an exception it will just echo the basic message instead of giving me the whole HTML message. I cannot figure out a way to do this. It seems like you can test for explicit exceptions, but you can't change in a general way the behavior of an exception, and you also can't mock up an object that extends a default php functionality. ( can't think of another example of this beyond exceptions... but it would seem to be the case ) I guess the problem is, where would you attach the mocked object?? It seems like you can't interfere with 'throw new' and this is the place that the object method is called.... Or if you could somehow use the existing phpunit exception functionality to change the exception behavior the way you want, in a general way for all your code... but this seems like it would be hacky and bad....

  • SQL: How do I INSERT primary key values from two tables INTO a master table.

    - by Stefan
    Hello, I would appreciate some help with an SQL statement I really can't get my head around. What I want to do is fairly simple, I need to take the values from two different tables and copy them into an master table when a new row is inserted into one of the two tables. The problem is perhaps best explained like this: I have three tables, productcategories, regioncategories and mastertable. --------------------------- TABLE: PRODUCTCATEGORIES --------------------------- COLUMNS: CODE | DESCRIPTION --------------------------- VALUES: BOOKS | Books --------------------------- --------------------------- TABLE: REGIONCATEGORIES --------------------------- COLUMNS: CODE | DESCRIPTION --------------------------- VALUES: EU | European Union --------------------------- --------------------------- TABLE: MASTERTABLE --------------------------- COLUMNS: REGION | PRODUCT --------------------------- VALUES: EU | BOOKS --------------------------- I want the values to be inserted like this when a new row is created in either productcategories or regioncategories. New row is created. --------------------------- TABLE: PRODUCTCATEGORIES --------------------------- COLUMNS: CODE | DESCRIPTION --------------------------- VALUES: BOOKS | Books --------------------------- VALUES: DVD | DVDs --------------------------- And a SQL statement copies the new values into the mastertable. --------------------------- TABLE: MASTERTABLE --------------------------- COLUMNS: REGION | PRODUCT --------------------------- VALUES: EU | BOOKS --------------------------- VALUES: EU | DVD --------------------------- The same goes if a row is created in the regioncategories. New row. --------------------------- TABLE: REGIONCATEGORIES --------------------------- COLUMNS: CODE | DESCRIPTION --------------------------- VALUES: EU | European Union --------------------------- VALUES: US | United States --------------------------- Copied to the mastertable. --------------------------- TABLE: MASTERTABLE --------------------------- COLUMNS: REGION | PRODUCT --------------------------- VALUES: EU | BOOKS --------------------------- VALUES: EU | DVD --------------------------- VALUES: US | BOOKS --------------------------- VALUES: US | DVD --------------------------- I hope it makes sense. Thanks, Stefan

    I’ll render an object graph on a page looking like this: Category 1 Module 1 Product 1 Product 2 Product 3 Module 2 Product 4 Category 2 ... The Category has an IList<Module and the Module contains an IList<Product Now I need to implement paging on this structure but the problem is that I can’t do Category.Skip(page * pageSize).Take(pageSize) because this will only work on the Category object not the whole object tree. In other words I like to render out when the sum of Categories, Modules and Products is equal to the PageSize /erik
