  • trying to set a dropdown in MVC

    - by RJ
    I almost have this solved but need a little push. Here's what I have: In the database I have a field called active that is a bit field (True/False) I have placed a dropdownlist on the View form like this: <%= Html.DropDownList("lstActive", new SelectList((IEnumerable)ViewData["ActiveList"])) %> In my controller, I simply have this code to generate the True/False in the dropdown: List<string> activeList = new List<string>(); activeList.Add("True"); activeList.Add("False"); ViewData["ActiveList"] = new SelectList(activeList); I want to bind to the field in the database called active and select it in the dropdown. When I view it like this I get this: So the questions are these: Obviously I am not pointing to the Value and Text property but what is that in this case? And how do I select the value that is in the database? Any help would be appreciated.

  • Dynamically generated controls issue.

    - by Thomas
    I have a form with a panel docked in it. I then dynamically create 15 panels (named: panel_n) and 15 pictureboxes (named: picturebox_n) on the primary panel (named ContainerPanel). When dragging the any picturebox over a panel (panel_n) created using the relevant mouse events. I would like to get the panel's name that the picture box was dragged over. The mouse cursor seems to be captured. I have tried creating a IMessageFilter interface, but there are still no events that trigger when dragging one of the pictureboxes over any one of the panels. The ClientRectangle.IntersectsWith function also does not work as the co-ords are always 0,0. All I need is the panel name where the picturebox was dragged over (preferably on the mouseup event)

    - by user1649439
    There is a example here. I am trying to use this technique in a large form with a list(List) but when I post back, the Viewmodel.Order that should’ve contained list of items and activities return with the lists empty.

  • Java: How to get Unicode name of a character (or its type category)?

    - by java.is.for.desktop
    Hello, everyone! The Character class in Java defines methods which check a given char argument for equality with certain Unicode chars or for belonging to some type category. These chars and type categories are named. As stated in given javadoc, examples for named chars are HORIZONTAL TABULATION, FORM FEED, ...; example for named type categories are SPACE_SEPARATOR, PARAGRAPH_SEPARATOR, ... However, being byte or int values instead of enums, the name of these types are "hidden" at runtime. So, is there a possibility to get characters' and/or type categories' names at runtime?

  • C# regularly return values from a different thread

    - by sdds
    Hello, I'm very new to multithreading and lack experience. I need to compute some data in a different thread so the UI doesn't hang up, and then send the data as it is processed to a table on the main form. So, basically, the user can work with the data that is already computed, while other data is still being processed. What is the best way to achieve this? I would also be very grateful for any examples. Thanks in advance.

  • Any dynamic database frontend tool from which you can update directly?

    - by Enjoy coding
    Hi Gurus, This is with reference to this question where I got one tabular report format. I need to update the user entered values correctly back to the same table rows. I am in the process of doing this by using general form post data methods by using some logics which I think will not be easy to maintain. So, just out of curiosity, Is there a front end creator javascript libraries or frameworks which can create the front end for any query's resultset and updates the corresponding rows when the user updates them from front end. This need not have all the full functionality, any one usable, customizable thing will reduce the code maintenance problems. I have googled for some javascript libraris for this but not able to get which will be suitable. Please suggest any useful tools. My environment is Mysql, PHP, JQuery, XAMPP server on Windows. Is JQuery provides one. Thanks in advance.

  • OpenGL Mapping Textures to a Grid Stored Inside Vertex Array

    - by Matthew Hoggan
    I am writing a test to verify something. This is not production code, just verification code. So I would appreciate it if the specific question was answered. I have code that uses indices and vertices to draw a set of triangles in the shape of a grid. All the vertices are drawn using glDrawElements(). Now for each vertex I will set its corresponding Texture Coordinates to 0 or 1 for each set of triangles that form a square in the grid. Basically I want to draw a collage of random textures in each one of the "squares" (consisting of two triangles). I can do this using the glBegin() and glEnd() method calls inside a for loop using the fixed functional pipeline, but I would like to know how to do this using Vertex Arrays.

  • LRU LinkedHashMap that limits size based on available memory

    - by sanity
    I want to create a LinkedHashMap which will limit its size based on available memory (ie. when freeMemory + (maxMemory - allocatedMemory) gets below a certain threshold). This will be used as a form of cache, probably using "least recently used" as a caching strategy. My concern though is that allocatedMemory also includes (I assume) un-garbage collected data, and thus will over-estimate the amount of used memory. I'm concerned about the unintended consequences this might have. For example, the LinkedHashMap may keep deleting items because it thinks there isn't enough free memory, but the free memory doesn't increase because these deleted items aren't being garbage collected immediately. Does anyone have any experience with this type of thing? Is my concern warranted? If so, can anyone suggest a good approach? I should add that I also want to be able to "lock" the cache, basically saying "ok, from now on don't delete anything because of memory usage issues".

  • How to center text in a select list

    - by Micah
    I'm having trouble styling a select list in an html form. Basically I want it to have a font size of 12px, and a height of 30px; The problem is that the box is drawn to the right hight, but the text rendering varies in each browser. In FireFox it renders it in the top left corner. I want to vertically center the text. Anyone know of a way to do this or do I need to make something custom out of a ul? Thanks

  • Passing parameters in VBA for Access

    - by Newbie
    In Access 2007 I have created a form with a textbox and a button. At the moment, when I press the button, I load a query with the textbox data passed as a parameter to the query criteria. I would like to change this so that all (manually input) options appear in a combobox (in place of the textbox). I would then like to pass the combobox text to a VBA module upon pressing the button. How do I do this? Similarly, I hope to output a different string from this module, and I hope to use this as the query criteria. How do I do this?

  • What is the standard way of using a sitemap with pages that require specific information passed to t

    - by Mike
    Hi, I have a website for which many pages rely on information passed to them (usually in the form of a querystring) or on a session variable. When making a web application, how do you normally handle these particular pages in regards to the sitemap? If you're using the standard ASP.NET menu control, it will render the node on the menu and if you click it, you could get an exception stating that a session variable doesn't exist (if it hasn't been created yet). For example, if you're making a user management area: All of these nodes get rendered, but I don't want the user to click on edit user or delete user without specifying someone to edit or delete. Any tips or suggestions would be greatly appreciated.

  • How to add on to an existing onclick event?

    - by Corey Sarnia
    I'm currently writing a Greasemonkey script for a page, so I can't modify the script myself. There is a form submit button on the page. When you click this button, it executes some fancy AJAX calls and such to update the page and do serverside things. What I'm trying to is basically set a "lastClick" value when the button is clicked. I want to add the code GM_setValue("lastClicked", (new Date()).getTime().toString()) to store the last time the button was clicked (for future uses of the script, it will actually do something with this date). How exactly can I accomplish this?

  • EF Query using .Contains() and .ToLowerInvariant() Results in no matches when match is found at the end of a string

    - by MyNameIsJob
    Is it possible to step into a linq query? I have a linq to entity framework 4 query in it's simplest form: List = List.Where(f => f.Value.ToString().ToLowerInvariant().Contains(filter.ToLowerInvariant())); It's a query against an Entity Framework DbContext and I'm having trouble seeing why it works for something like: List searching for 001 yields no results against the following list Test001 Test002 Test003 Test004 However any other search yields results (Such as t00 or Test) Update Basically I'm looking for why a query such as the above wouldn't return a result when I'm using a contains and the value matches the end of a string vs just the middle or begining. It's really confusing. OK, it appears to have something to do with ToLowerInvariant() - when I removed that method it works just fine.

  • Default datetime format in mySQL

    - by Davuz
    I'm coding to search data by compare datetime. In web form, user input value '2012-06-04' store in $_REQUEST['dateSearch']. I create datetime object from that: $dateObj = date_create_from_format("Y-m-d",$_REQUEST['dateSearch']); $dateParam = $dateObj->format("Y-m"); Then I use $dateParam in sql query to find data $sql = " SELECT * FROM `temp` as `t` WHERE `t`.`date` LIKE '$dateParam%' "; Everything is ok, but I'm not sure mySQL alway use only one datetime format "Y-m-d H:i:s". At here, $dateParam = $dateObj->format("Y-m"); I set default format is "Y-m". Is the default format never change? I don't want hard set format "Y-m-d H:i:s" in code, instead of, I think get format string from system to use is better. How do I get default datetime format string from mySQL???

  • Javascript : random number between variables issue

    - by Mayhem
    I've seen the other examples on this site but I just can't get it to work. I'm trying to generate a random number between 2 user input variables on a form. The numbers will always be positive numbers. min = document.getElementById('min').value; max = document.getElementById('max').value; waitTimer = Math.floor(Math.random() * (max - min + 1)) + min; When min = 5 / max = 10, waitTimer is sometimes returning results like 2, 4 and 28 and so on. What am I doing wrong?

  • How to coerce type of ActiveRecord attribute returned by :select phrase on joined table?

    - by tribalvibes
    Having trouble with AR 2.3.5, e.g.: users = User.all( :select => "u.id, c.user_id", :from => "users u, connections c", :conditions => ... ) Returns, e.g.: => [#<User id: 1000>] >> users.first.attributes => {"id"=>1000, "user_id"=>"1000"} Note that AR returns the id of the model searched as numeric but the selected user_id of the joined model as a String, although both are int(11) in the database schema. How could I better form this type of query to select columns of tables backing multiple models and retrieving their natural type rather than String ? Seems like AR is punting on this somewhere. How could I coerce the returned types at AR load time and not have to tack .to_i (etc.) onto every post-hoc access?

  • html5 offline storage for Windows Mobile 6.1 or an alternative?

    - by SimonNet
    I understand that there are no browsers currently which support offline storage for mobile 6.1. I am trying to find a web form based solution avoiding the loss of data when my device has no connectivity. Have ruled out Gears and would like to avoid a win forms application as the forms change so often. Are there any other approaches that I should look at which are viable in C#? Are there any estimated dates for when we might see a browser for mobile 6.1 which can offer offline storage? Thanks

  • ASP MVC html helpers in partial views

    - by Rabbi
    I am still trying to figure out how to create reusable partial views in MVC Lets say I would like to create a partial view to display a form for submitting an address. Then in my ViewModel I have two addresses (Home address & Work Address) So I would think that in my view I call HTML.Partial for each one like this @Html.Partial("Address", Model.HomeAddress) @Html.Partial("Address", Model.WorkAddress) but what happens is instead of the fields having names like HomeAddress.Street, HomeAddress.City etc. they just have the regular field names Street, City, etc. so the binder on the HTTPPost action has no idea what to do with them Thanks in advance

  • Having a UITextField in a UITableViewCell

    - by Mathieu
    Hi! I'm trying to do that for a couple of days now, and after reading tons of messages of people trying to do that too, I'm still unable to have a fully working UITextField in some of my UITableViewCells, just like in this example: http://img231.imageshack.us/img231/4858/picture4za3.png Either I have the form working but the text is not visible (although I set its color to blue), the keyboard goes on the field when I click on it and I haven't been able to correctly implement the keyboard events. I tried with a bunch of examples from Apple (mainly UICatalog, where there is a kinda similar control) but it's still not working correctly. Can somebody help me (and all the people trying to realize this control) and post a simple implementation of a UITextField in a UITableViewCell, that works fine? Thank you very much.

  • casting odd smallint time to to datetime format.

    - by c6400sc
    Hello everyone, I'm working with a db (SQL server 2008), and have an interesting issue with times stored in the db. The DBA who originally set it up was crafty and stored scheduled times as smallints in 12-hour form-- 6:00AM would be represented as 600. I've figured out how to split them into hours and minutes like thus: select floor(time/100) as hr, right(time, 2) as min from table; What I want to do is compare these scheduled times to actual times, which are stored in the proper datetime format. Ideally, I would do this with two datetime fields and use datediff() between them, but this would require converting the smallint time into a datetime, which I can't figure out. Does anyone have suggestions on how to do this? Thanks in advance.

  • Freelancer - client agreement. What things are worth to write explicitely?

    - by Dzida
    Hi guys, This is not technical question, though I think it is quite important for software developers who work as a freelancers. There is some general good advice to make paper contracts before starting new jobs. When I started my work as a freelancer I hadn't got any clue how such contract should looks like. Now I have some ideas but I believe many of freelancers gathered on SO can add some interesting advices for less-experienced colleagues (like me). So the question is: what clauses freelancers should put on agreements with their clients to make their projects less stressful and better secured. What are your experiences here? PS: Please write your country on the bottom of your post - I guess some stuff might be country specific. Probably there are differences in form of agreements depending on country where business is made.
