• Minimum & Maximum Values in Crystal Reports 2008 Column

  - by GregD

  Say I have this column returned in a command for Crystal: deposit_no 123 130 125 124 126 127 128 129 and I need to have this in the report title: Includes deposits between 123 - 130 I've tried a running formula for minimum and maximum and they aren't returning the correct values no matter how I manipulate them. I've tried evaluate for every record, on change of the deposit_no field, etc. I have no grouping on this report. Edited to add: While I preferred to handle this on the CR side of things, I changed my command to include what mson wrote below. So technically, mson had the correct answer.

• Pygame program that can get keyboard input with caps

  - by None

  I have a Pygame program that needs text input. The way it does this is to get keyboard input and when a key is pressed it renders that key so it is added to the screen. Essentially it acts like a text field. The problem is, when you hold shift it doesn't do anything. I relize this is because the program ignores shift input and instead writes the text if it's number is under 128. I have thought of setting a variable when shift is pressed then capitalizing if it was true, but string capitalization only woks on letters, not things like numbers or semicolons. Is there maybe a number I can add to the ascii number typed to modify it if shift is pressed, or something else?

• Best calculator software to help programmers

  - by RHaguiuda

  As a embedded systems programmer I always need to make lots of base conversions (dec to hex, hex to bin and so on...), and I must admit: Windows 7 calculator is a good calc, but too limited in my point of view. I work a lot with communications protocols and it`s common to need some base conversion in this field of knowledge. I`m looking for a calculator software (not a hardware one), to help with base conversions, but it must also support scientific calc. Can anyone help on this? Since this subject is intended to help programmers, I did not ask this in SuperUser.com. Thanks.

• ActiveRecord fundamentally incompatible with composite keys?

  - by stimms

  I have been attempting to use subsonic for a project on which I'm working. All was going quite well until I encountered a link table with a composite primary key. That is a key made up of the primary keys of the two tables it joins. Subsonic failed to recognize both keys which was problematic. I was going to adjust subsonic to support compound keys but I stopped and though "Maybe there is a reason for this". Normally active record relies on a single primary key field for every record, even in link tables. But is this necessary? Should I just give up on active record for this project or continue with my modifications?

• Added tagging to existing model, now how does its admin work?

  - by Oli

  I wanted to add a StackOverflow-style tag input to a blog model of mine. This is a model that has a lot of data already in it. class BlogPost(models.Model): # my blog fields try: tagging.register(BlogPost) except tagging.AlreadyRegistered: pass I thought that was all I needed so I went through my old database of blog posts (this is a newly ported blog) and copied the tags in. It worked and I could display tags and filter by tag. However, I just wrote a new BlogPost and realise there's no tag field there. Reading the documentation (coincidentally, dry enough to be used as an antiperspirant), I found the TagField. Thinking this would just be a manager-style layer over the existing tagging register, I added it. It complained about there not being a Tag column. I'd rather not denormalise on tags just to satisfy create an interface for inputting them. Is there a TagManager class that I can just set on the model? tags = TagManager() # or somesuch

• xval get message from resource file

  - by Rob

  I'm working on a CMS system which uses a resource file to get information and errormessages from. The client side validation is working without problems, only it's not getting the errormessage from the resource file. While debugging i figured out xval seems to get the errormessages from a javascript file where the messages are set hard-coded. Is there some way to override this? Below the code which should make the relation to the resourcefile en specify the error when the field is left empty. [Property] [Required(ErrorMessageResourceType = typeof(CMSMessages), ErrorMessageResourceName = "EnterValidMoney")] public virtual Double ShippingCost { get; set; }

• Help with MVC controller: passing a string from view to controller

  - by 109221793

  Hi guys, I'm having trouble with one particular issue, I was hoping someone could help me out. I've completed the MVC Music Store tutorial, and now I'm trying to add some administrator functionality - practice as I will have to do this in an MVC application in my job. The application is using the aspnet membership api, and what I have done so far is created a view to list the users. What I want to be able to do, is click on the users name in order to change their password. To try and carry the username to the changeUserPassword controller (custom made). I registered a new route in the global.asax.cs file in order to display the username in the URL, which is working so far. UserList View <%: Html.RouteLink(user.UserName, "AdminPassword", new { controller="StoreManager", action="changeUserPassword", username = user.UserName }) %> Global.asax.cs routes.MapRoute( "AdminPassword", //Route name "{controller}/{action}/{username}", //URL with parameters new { controller = "StoreManager", action = "changeUserPassword", username = UrlParameter.Optional} ); So now the URL looks like this when I reach the changeUserPassword view: http://localhost:51236/StoreManager/changeUserPassword/Administrator Here is the GET changeUserPassword action: public ActionResult changeUserPassword(string username) { ViewData["username"] = username; return View(); } I wanted to store the username in ViewData as I would like to use it in the GET changeUserPassword for display purposes, and also as a hidden value in the form. This is in order to pass it through to enable me to reset the password. Having debugged through the code, it seems that 'username' is null. How can I get this to work so that the username carries over from the Html.RouteLink, to the changeUserPassword action? Any help would be appreciated :) Here is my complete code: UserList.aspx <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<System.Web.Security.MembershipUserCollection>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> UserList </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>UserList</h2> <table> <tr> <th>User Name</th> <th>Last Activity date</th> <th>Locked Out</th> </tr> <%foreach (MembershipUser user in Model){ %> <tr> <td><%: Html.RouteLink(user.UserName, "AdminPassword", new { controller="StoreManager", action="changeUserPassword", username = user.UserName }) %></td> <td><%: user.LastActivityDate %></td> <td><%: user.IsLockedOut %></td> </tr> <% }%> </table> </asp:Content> changeUserPassword.aspx <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<musicStoreMVC.ViewModels.ResetPasswordAdmin>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> changeUserPassword </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Change Password: <%: ViewData["username"] %></h2> <% using (Html.BeginForm()) {%> <%: Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%: Html.Hidden("username",ViewData["username"]) %> <%: Html.LabelFor(model => model.password) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.password) %> <%: Html.ValidationMessageFor(model => model.password) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.confirmPassword) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.confirmPassword) %> <%: Html.ValidationMessageFor(model => model.confirmPassword) %> </div> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %> <div> <%: Html.ActionLink("Back to List", "Index") %> </div> </asp:Content> My actions public ActionResult UserList() { var users = Membership.GetAllUsers(); return View(users); } public ActionResult changeUserPassword(string username) { ViewData["username"] = username; return View(); }

• ASP.NET MVC authorization & permission to use model classes

  - by Tomek

  Hi, This is my first post here, so hello :) Okey, let's get to the point... I am writing my first app in ASP.NET MVC Framework and i have a problem with checking privileges to use instances of model classes (read, edit). Sample code looks like this: // Controller action [CustomAuthorize(Roles="Editor, Admin")] public ActionResult Stats(int id) { User user = userRepository.GetUser(id); if (user == null || !user.Activated || user.Removed) return View("NotFound"); else if (!user.IsCurrentSessionUserOwned) return View("NotAuthorized"); return View(user); } So far authorize attribute protects only controller actions, so my question is: how to make (custom) authorize attribute to check not only user role, usernames but also did i.e. resources instantiated in action methods (above: User class, but there are other ORM objects like News, Photos etc.) All of these object to check have their unique ID's, so user have own ID, News have their ID and UserID field referecned to Users table (i mean these objects are LINQ2SQL classes). How should i resolve that problem?

• vb.net Object Initialiser List(Of T)

  - by Tim B James

  I have been looking at some C# code: List<Employee> Employees = new List<Employee>{ new Employee{firstname="Aamir",lastname="Hasan",age=20}, new Employee{firstname="awais",lastname="Hasan",age=50}, new Employee{firstname="Bill",lastname="Hasan",age=70}, new Employee{firstname="sobia",lastname="khan",age=80}, }; Now when I convert this to vb.net Dim Employees as List(Of Employee) = New List(Of Employee)() With { New Employee() With { _ .firstname = "Aamir", _ .lastname = "Hasan", _ .age = 20 _ }, _ New Employee() With { _ .firstname = "awais", _ .lastname = "Hasan", _ .age = 50 _ }, _ New Employee() With { _ .firstname = "Bill", _ .lastname = "Hasan", _ .age = 70 _ }, _ New Employee() With { _ .firstname = "sobia", _ .lastname = "khan", _ .age = 80 _ } _ } I get the error "Name of field or property being initialized in an object initializer must start with'.'." Now I can get an array of employee using the code: Dim Employees = { New Employee() With { _ .FirstName = "Aamir", _ .LastName = "Hasan", _ .Age = 20}, _ New Employee() With { _ .FirstName = "Awais", _ .LastName = "Hasan", _ .Age = 50}, _ New Employee() With { _ .FirstName = "Bill", _ .LastName = "Hasan", _ .Age = 70 _ } _ } But I would like a List(Of Employee) as it is bugging me as to why this doesnt work in vb.net?

• What would be the disadvantages/risks of using AF_UNSPEC?

  - by Kiril Kirov

  From Beej's Guide to Network programming You can force it to use IPv4 or IPv6 in the ai_family field, or leave it as AF_UNSPEC to use whatever. This is cool because your code can be IP version-agnostic. As the title says - what would be the disadvantages (or risks, if any) of always using AF_UNSPEC, instead of specifying IPv4 or IPv6? Or it's only for one reason - if the version is specified, this will guarantee that this and only this version is supported? A little background - I think about adding support for IPv6 in client-server (C++) applications and both versions should be supported. So I wondered if it's fine to use AF_UNSPEC or it's better to "recognize" the address from the string and use AF_INET6 or AF_INET, depending on the address.

Any ideeas?

• More complex view matrix calculation required to composite 3d models with 2d video

  - by lzcd

  I'm utilising some 2d / 3d tracking data (provided by pfHoe) to help integrate some 3d models into the playback of some 2d video. Things are working.... okay... but there's still some visible 'slipping' of the models against the video background and I suspect this is may be because the XNA CreatePerspective helper method isn't taking into account some of the additional data supplied by pfHoe such as independent horizontal / vertical field of view angles and focal length. Would anyone be able to point me towards some examples of constructing view matrices that include such details?

• Entity-attribute-value model using codeigniter / php

  - by John Stewart

  SO I am trying to create a way to structure my database to be able customize forms. I looked into EAV pattern and here is my db structure: Table form - form_id - form_name - form_added_on - form_modified_at Table: form_fields - field_id - form_id - field_type (TEXT, RADIO etc..) - field_default_value - field_required Table: form_data - data_id - field_id - form_id - field_value so now I can store any custom form into the database and if I want to get the values for an individual form I can simply join it by "form_id" .. the problem: I want to be able to search through all the forms for a specific field value. How can I do that with EAV model? Also, I thought about just storing the custom data as a serialized (JSON) object but then I am not sure how can I query that data. Please note that I am using Codeigniter with MYSQL. So if conversation can use Codeigniter libraries if needed.

• Thoughts/Input about Database Design for a CMS

  - by dallasclark

  I'm just about to expand the functionality of our own CMS but was thinking of restructuring the database to make it simpler to add/edit data types and values. Currently, the CMS is quite flat - the CMS requires a field in the database for every type of stored value (manually created). The first option that comes to mind is simply a table which keeps the data types (ie: Address 1, Suburb, Email Address etc) and another table which holds values for each of these data types. Just like how Wordpress keeps values in the 'options' table, PHP serialize would be used to store an array of values. The second option is how Drupal works, the CMS creates tables for every data type. Unlike Wordpress, this can be a bit of an overkill but really useful for SQL queries when ordering and grouping by a particular value. What's everyone's thoughts?

• How would you communicate with aliens as a computer scientist?

  - by Pyrolistical

  Let's say aliens arrive on Earth and instead of just sending mathematicians and linguistic experts governments around the work decide to send an expert of major field. After a quick round of sorting you are paired up with an alien computer scientist. Given you don't understand each others language how would you using computer science to start the ground work of communication? eg. We know binary is universal, but not the way we write it. The symbols are not universal nor is the the direction we write it (MSB vs LSB and left vs right) Assume aliens are "similar" to us physically it won't impede visual communication.

• Sql Paging/Sorting - Efficent method with dynamic sort?

  - by dmose

  I'm trying to implement this style of paging: http://www.4guysfromrolla.com/webtech/042606-1.shtml CREATE PROCEDURE [dbo].[usp_PageResults_NAI] ( @startRowIndex int, @maximumRows int ) AS DECLARE @first_id int, @startRow int -- A check can be added to make sure @startRowIndex isn't > count(1) -- from employees before doing any actual work unless it is guaranteed -- the caller won't do that -- Get the first employeeID for our page of records SET ROWCOUNT @startRowIndex SELECT @first_id = employeeID FROM employees ORDER BY employeeid -- Now, set the row count to MaximumRows and get -- all records >= @first_id SET ROWCOUNT @maximumRows SELECT e.*, d.name as DepartmentName FROM employees e INNER JOIN Departments D ON e.DepartmentID = d.DepartmentID WHERE employeeid >= @first_id ORDER BY e.EmployeeID SET ROWCOUNT 0 GO This method works great, however, is it possible to use this method and have dynamic field sorting? If we change this to SELECT e.*, d.name as DepartmentName FROM employees e INNER JOIN Departments D ON e.DepartmentID = d.DepartmentID WHERE employeeid >= @first_id ORDER BY e.FirstName DESC It breaks the sorting... Is there any way to combine this method of paging with the ability to sort on different fields?

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

  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 :(

• How to check if a variable is defined in a Master file in ASP.NET MVC

  - by Mortanis

  I've got a Site.Master file I've created to be my template for the majority of the site, with a navigation. This navigation is dynamically created, based on a recursive Entity (called Page) - Pages with a parentID of 0 are top level, and naturally each child carries it's parent's Id in that field. I've created a quick little HTML Helper that accepts the ID of an Page and generates the nav by doing a foreach on the children that have a parentId matching the passed Id. On the majority of the site, I want the Site.Master to use a parentId of 0, but if I'm on a strongly typed View displaying a Page, I naturally want to use the Id of the page. Is there a way to do such conditional logic in a Site.Master (and, does that violate MVC rules)? "If I'm on a strongly typed Page of /Page/{Id}, use the Id render nav, else use 0"

• HQL query for entity with max value

  - by Rob

  I have a Hibernate entity that looks like this (accessors ommitted for brevity): @Entity @Table(name="FeatureList_Version") @SecondaryTable(name="FeatureList", pkJoinColumns=@PrimaryKeyJoinColumn(name="FeatureList_Key")) public class FeatureList implements Serializable { @Id @Column(name="FeatureList_Version_Key") private String key; @Column(name="Name",table="FeatureList") private String name; @Column(name="VERSION") private Integer version; } I want to craft an HQL query that retrieves the most up to date version of a FeatureList. The following query sort of works: Select f.name, max(f.version) from FeatureList f group by f.name The trouble is that won't populate the key field, which I need to contain the key of the record with the highest version number for the given FeatureList. If I add f.key in the select it won't work because it's not in the group by or an aggregate and if I put it in the group by the whole thing stops working and it just gives me every version as a separate entity. So, can anybody help?

• ASP.NET Call Another Element's DoPostBack Function

  - by blu

  I have an ASP.NET control that has an onclick event handler rendered inline on the element. I would like to call that function and have it raise the target control's server side event handler. <asp:CheckBox ID="Foo" runat="server" AutoPostBack="true" Text="Foo" /> <a href="#" onclick="javascript:setTimeout('__doPostBack(\'Foo\',\'\')', 0)">Test </a> I created the checkbox, looked at the rendered function on the field, and then copied that into the onclick on the anchor element. The anchor will raise a postback, but the event handler for the check box is not raised. protected override void OnLoad(EventArgs e) { // fires for checkbox // fires for anchor (the anchor does cause a postback) } void Foo_CheckedChanged(object sender, EventArgs e) { // fires for checkbox // does not fire for anchor } protected override void OnInit(EventArgs e) { this.Foo.CheckedChanged += new EventHandler(Foo_CheckedChanged); } Is it possible to do this?

• Better way to clean this messy bool method

  - by Luís Custódio

  I'm reading Fowler Clean Code book and I think that my code is a little messy, I want some suggestions: I have a simple business requirement that is return the date of new execution of my Thread. I've two class fields: _hour and _day. If actual day is higher than my _day field I must return true, so I'll add a month to "executionDate" If the day is the same, but the actual hour is higher than _hour I should return true too. So I did this simple method: private bool ScheduledDateGreaterThanCurrentDate (DateTime dataAtual) { if (dateActual.Day > _day) { return true; } if (dateActual.Day == _day && dateActual.Hour > _hour) { return true; } if (dateActual.Day == _day && dateActual.Hour == _hour) if (dateActual.Minute>0 || dateActual.Second>0) return true; return false; } I'm programming with TDD, so I know that the return is correct, but this is bad maintain code right?
