• A very weird problem with texbox control in .net

  - by Kazoom

  Well i know textbox is a very simple user control, perhaps the first input control ever made. I have been facing a very frustrating problem with this simple control. I programatically add a textbox in my user control. From ui i am able to edit it like a normal textbox. however, i am not able to read the user inputed value in the program. my program all the time sees the old value with which my text box was initialized. i textchange event getting triggered but the value never gets updated. This seemingly looks to be some innocuous bug in the code, but the program is very simple and it does not seem to be having any bug. Any guidelines on this issue?

• Windows 7 sticky notes - better alternative?

  - by Ben

  Hi guys, i like the post it sidebar app in windows 7, but it offers almost no features and so I'm looking for an alternative. Some of this features would be nice: - easy font formatting - better resizeable - an simple alert function It should be small and simple to use, and not bloated with tons of features which are not often neede. I was searching for a while but cant find something propper. Anybody has an idea? Thanks!

• How would I best address this object type heirachy? Some kind of enum heirarchy?

  - by FerretallicA

  I'm curious as to any solutions out there for addressing object heirarchies in an ORM approach (in this instance, using Entity Framework 4). I'm working through some docs on EF4 and trying to apply it to a simple inventory tracking program. The possible types for inventory to fall into are as follows: INVENTORY ITEM TYPES: Hardware PC Desktop Server Laptop Accessory Input (keyboards, scanners etc) Output (monitors, printers etc) Storage (USB sticks, tape drives etc) Communication (network cards, routers etc) Software What recommendations are there for handling enums in a situation like this? Are enums even the solution? I don't really want to have a ridiculously normalised database for such a relatively simple experiment (eg tables for InventoryType, InventorySubtype, InventoryTypeToSubtype etc). I don't really want to over-complicate my data model with each subtype being inherited even though no additional properties or methods are included (except PC types which would ideally have associated accessories and software but that's probably out of scope here). It feels like there should be a really simple, elegant solution to this but I can't put my finger on it. Any assistance or input appreciated!

• How should objects be in a Java game.

  - by Gabriel A. Zorrilla

  EDIT: i just deleted the entire post and reformulated the question to be more generic. I want to do a simple strategy game: map, units. Map: one class. Units: another class, self drawn. Simple questions: How does an unit should redraw itself on the map. A unit should be a JPanel or similar Swing component (just to be able to manage them as an entity with its own mousehandlers) or can be another thing, without neglecting the fact that it should be an autonomous object with its own action handlers and fields. Is this map-units model correct of a simple game that would help me to learn in a fun way Java and OOP fundamentals. Thats it!

• Web interface to allow users to change their Active Directory password

  - by csexton

  I have a few web applications that use Active Directory to authenticate. What I would like to be able to do is provide a simple web page that would allow users to update their AD password. This wasn't a problem when the majority of the users had windows machines that connected to this AD server (and could ctrl-alt-del to change the password), but we are moving away from that and the AD server is mostly for web apps. Is there a simple solution for this, or am I looking at the big LDAP managers?

• Any exprience with Castle ActiveRecord?

  - by afsharm

  Hi all, I was searching for a light data access framework based on NHibernate. I needed simple CRUD and some simple HQL or LINQ-to-NHhibernate queries. Performance was not an important issue and applications which I'm working on have simple table structure but many tables. This data access framework is going to be used in a ASP.NET Webform application. Once a time I found S#harp architecture, but it was developed for ASP.NET MVC. Just today I found Castle ActiveRecord. But I'm wondering: If any one has any experience with it? Is it suitable for me? Should I consider any specific matter? What about its future? Is Castle ActiveRecord supposed to be developed and be active in coming years? Thanks in Advance

• How can I add an Items-like property to my User Control?

  - by Dan Tao

  It's pretty straightforward to add simple properties to a User Control that will appear in the desired categories in the Windows Forms designer, e.g.: [Category("Appearance")] public Color BackColor { get { return _textBox.BackColor; } set { _textBox.BackColor = value; } } What if I want to expose a more complex property, such as a collection of items of a type I define? I'm thinking something along the lines of the ListView.Items property, or the DataGridView.Columns property -- where the user of the control can access this complex property via a more specialized pop-up form (as opposed to a simple TextBox or ComboBox). Even a simple nudge in the right direction would be much appreciated.

• How to code Fizzbuzz in F#

  - by Russell

  I am currently learning F# and have tried (an extremely) simple example of FizzBuzz. This is my initial attempt: for x in 1..100 do if x % 3 = 0 && x % 5 = 0 then printfn "FizzBuzz" elif x % 3 = 0 then printfn "Fizz" elif x % 5 = 0 then printfn "Buzz" else printfn "%d" x What solutions could be more elegant/simple/better (explaining why) using F# to solve this problem? Note: The FizzBuzz problem is going through the numbers 1 to 100 and every multiple of 3 prints Fizz, every multiple of 5 prints Buzz, every multiple of both 3 AND 5 prints FizzBuzz. Otherwise, simple the number is displayed. Thanks :)

• Segmentation Fault when using "mov" in Assembly

  - by quithakay207

  I am working on a simple assembly program for a class, and am encountering an odd segmentation fault. It's a pretty simple program to convert bytes into kilobytes. However, within the function that does the conversion, I get a segmentation fault when I try to move the value 1024 into the ebx register. I've never had this kind of problem before when working with registers. Does someone know what could be causing this? I imagine it is something simple that I'm overlooking. Thank you! asm_main: enter 0,0 pusha mov eax, 0 mov ebx, 0 call read_int push eax call functionA popa mov leave ret functionA: mov eax, [esp + 4] call print_int call print_nl mov ebx, 1024 ;segmentation fault occurs here div ebx call print_int ret UPDATE: One interesting discovery is that if I delete the lines interacting with the stack, push eax and mov eax, [esp + 4], there is no longer a segmentation fault. However, I get a crazy result in eax after performing div ebx.

• How can I define pre/post-increment behavior in Perl objects?

  - by Zaid

  Date::Simple objects display this behavior. In the case of Date::Simple objects, $date++ returns the next day's date. Date::Simple objects are immutable. After assigning $date1 to $date2, no change to $date1 can affect $date2. This means, for example, that there is nothing like a set_year operation, and $date++ assigns a new object to $date. How can one custom define the pre/post-incremental behavior of an object, such that ++$object or $object-- performs a particular action? I've skimmed over perlboot, perltoot, perltooc and perlbot, but I don't see any examples showing how this can be done.

• Console-like control that allows full control over individual text formatting

  - by Rich.Carpenter

  I'm tinkering with writing a simple text-based role-playing game. I would like to use WinForms, and utilize WinForm controls for the UI and simple text for the output. The catch is, I would like to have complete control over the formatting of the individual text - some words being different colors, etc. A simple console control would suffice, as that would provide control over text colors, but it would be nice to also be able to change style, font and size. Less important: it would be nice to have complete control over where text appears in the control through a coordinate system, as with DOS windows of old. I'd appreciate suggestions on the best method of implementing this. Perhaps there is a better method I had not considered for rendering the output of a text-based game.

• Notepad++ Search & Replace with Regular Expressions

  - by Jeremy

  I know its simple, but I can't get it to work... I have a strings like {span style="display:none"}123{/span} and {span style="display:none"}456{/span} and {span style="display:none"}789{/span} in a file. I want to remove all of these string. So, I thought a simple regular expression replace in NotePad++ should be like "{span style="display:none"}[(.)]{/span}" - but, this is not working. Thank for your help!

• Ubuntu Server Port Forwarding the easy way?

  - by Arthur Ulfeldt

  I have an Ubuntu server (10.04) running nat and I understand how to forward ports using iptables which works fine and is only mildly painful. What is "the easy way" of doing this? Is there some nice wiz-bang-network-tool (like ufw) that makes simple port forwarding super simple.

• jQuery: jquery form plugin syntax?

  - by k00k

  I'm using jquery with the jquery form plugin. I read through a bunch of posts, the docs, etc., and I'm still having trouble with what I believe to be simple. I have a form with some simple text inputs and a couple textareas, and I have this link that I want to trigger submission of that form to a specific method (/email): <a id="email-data">Send Email</a> and this jquery in doc ready: $('#email-data').click(function() { var options = { url: '/email/', success: alert('Email sent.') }; $('#report-giftcard-sales-form').ajaxSubmit(options); }); So I would expect it to submit to my /email method, but no such luck. Currently I just have the /email method logging a debug message, so it's as simple as can be. Any help is greatly appreciated.

• zend framework can't find Model classes ?

  - by user284503

  Yall: I have a simple question, it might be a simple configuration issue, but I have a Model defined, and when I try to access it from a controller it fails. The Model is in the model directory, and when I look at the quickstart app, it seems like this should work. Here is my model: <?php class Application_Model_User { protected $_user; protected $_password; protected $_userId; // very simple right } ?> My controller just stops.. here is the controller code: <?php class UserController extends Zend_Controller_Action { public function init() { } public function indexAction() { // display login form $users = new Application_Model_User(); echo "test never echos.. stopped above ? weird huh.."; // fails before .. } ?> Thank you everyone,

• SingleTap on UIScrollView

  - by ludo

  Hi, I see many post dealing with the UIScrollView like in the PhotoApp, but I don't really understand them, thats why I want to reopen a post about it and have a simple solution. What I want is to create (without IB) a simple UIViewController who will contain a UIScrollView (inside my scrollView there will be image and the scrollView will be set to pagingEnable to YES of course). I want to be able with a simple touch of the screen to display the navigationController.navigationBar inside my UIViewController and with another touch not displaying it of course. Can anyone show me how to implement that? thanks,

• Algorithm for Source Control System?

  - by Michael Stum

  I need to write a simple source control system and wonder what algorithm I would use for file differences? I don't want to look into existing source code due to license concerns. I need to have it licensed under MPL so I can't look at any of the existing systems like CVS or Mercurial as they are all GPL licensed. Just to give some background, I just need some really simple functions - binary files in a folder. no subfolders and every file behaves like it's own repository. No Metadata except for some permissions. Overall really simple stuff, my single concern really is how to store only the differences of a file from revision to revision without wasting too much space but also without being too inefficient (Maybe store a full version every X changes, a bit like Keyframes in Videos?)

• What is the best SVN client for Windows?

  - by Nick

  I am familiar with using both Versions and Cornerstone on Mac - they are fantastic and incredibly simple to use... but I don't want to always rely on being able to borrow my girlfriend's MacBook so need to find an alternative for my Windows machine. Can anyone please recommend a good subversion client? I have experimented using Tortoise and RapidSVN and couldn't even get them working :( I'd like something just incredibly simple if possible. Thank you!

• Windows Azure Backup agent with Windows 7 pro

  - by J King

  I know that windows azure backup is designed to work with windows server, but I have a small client that runs a little windows 7 pro machine as a "server/file share" in their office and I want to set up a simple back-up for them. As I work with Azure in other ways with the client I would like to use azure for this solution as well. Will windows azure backup agent work with windows 7 pro? It would just be backing up some simple files/folders. Thanks

• SQL Server - Compare int values in a select clause

  - by Russell

  This is what I thought would be a simple select clause, however the following is giving me grief! I am using SQL Server 2008. Basically I want to compare two integer values and return the boolean result in the select clause. Here is a simple example: DECLARE @A INT DECLARE @B INT SET @A = 1 SET @B = 2 SELECT @A = @B Currently the only output is "Command(s) completed successfully." Where I reasonably believe it is assigning @A to @B. I thought this would be simple but have not been able to achieve this. Any help would be great! Thanks

• Android MapView with High Res tiles?

  - by Nemi

  I have created a simple map app that shows the local garage sales in my town. It was simple enough to create and I parse out the Google Maps (html) xml doc that the local paper uses on their google maps mashup on their website. I have noticed that the Map Tiles used in the MapView class are not as high-res as the tiles used in the real Android Google Maps app (I have a Droid). I have searched the docs and google, but I cannot find any info on this. Actually, I can't even find anyone mentioning this, which surprises me and makes me think I am missing something simple. Is this a case of Google making the APIs available, but at a lower quality, or am I missing some setting that enables higher quality map tiles?
