  • Namespace constraint with generic class decleration

    - by SomeGuy
    Good afternoon people, I would like to know if (and if so how) it is possible to define a namespace as a constraint parameter in a generic class declaration. What I have is this: namespace MyProject.Models.Entities <-- Contains my classes to be persisted in db namespace MyProject.Tests.BaseTest <-- Obvious i think Now the decleration of my 'BaseTest' class looks like so; public class BaseTest<T> This BaseTest does little more (at the time of writing) than remove all entities that were added to the database during testing. So typically I will have a test class declared as: public class MyEntityRepositoryTest : BaseTest<MyEntity> What i would LIKE to do is something similar to the following: public class BaseTest<T> where T : <is of the MyProject.Models.Entities namespace> Now i am aware that it would be entirely possible to simply declare a 'BaseEntity' class from which all entities created within the MyProject.Models.Entities namespace will inherit from; public class BaseTest<T> where T : MyBaseEntity but...I dont actually need to, or want to. Plus I am using an ORM and mapping entities with inheritance, although possible, adds a layer of complexity that is not required. So, is it possible to constrain a generic class parameter to a namespace and not a specific type ? Thank you for your time.

  • Problem with displaying image from DB using asp.net MVC 2

    - by Renato
    Hello! I'm having trouble with displaying image from db. I think that method for saving image is working, because I see in DB that varbinary fields have some value, and that image type is correct. Also the size of image. But when I want to display image for product i don't get anything. Just blank space.. here is my code... public byte[] GetImage(int productID) { Product product = products.GetByID(productID); byte[] imageData = product.ImageData.ToArray(); return imageData; } That code is in my controller. Second is code from view : <% if (product.ImageData != null) { %> <img src='/product/getimage/<%= Html.Encode(product.ID) %>' alt=""/> <% } %> I tried some solutions found here on stack overflow, and everyone do it like this, but it's working for them. I dont have any idea why images aren't displayed. When i look at source code of page at debugging i have : <img src='/product/getimage/18' alt=""/> I'm using .net 4.0, MVC 2, VS 2010... Thanks in advance

    So, i am using this code to get the whole HTML of a website.

  • Populate an unmapped property of domain object from result of join with Nhibernate

    - by Adam Pope
    I have a situation where I have 3 tables: StockItem, Office and StockItemPrice. The price for each StockItem can be different for each Office. StockItem( ID Name ) Office( ID Name ) StockItemPrice( ID StockItemID OfficeID Price ) I've set up a schema with 2 many-to-one relations to link StockItem and Office. So in my StockItem domain object I have a property: IList<StockItemPrice> Prices; which gets loaded with the price of the item for each office. That's working fine. Now I'm trying to get the price of an item for a single office. I have the following Criteria query: NHibernateSession.CreateCriteria(persistentType) .Add(Restrictions.Eq("ID", id)) .CreateAlias("Prices", "StockItemPrice") .Add(Restrictions.Eq("StockItemPrice.Office", office)) .UniqueResult<StockItem>(); This appears to work fine as the SQL it generates is what I qould expect. However, I dont know if it populates StockItem.Prices with a single object correctly as as soon as I reference that property NHibernate performs a lazy load of all the office's prices. Also, even if it does work, it feels really crufty having to access the price by using: mystockitem.Prices[0].Price What I would really like is to have a Price field on the StockItem object and have the price of the item put into that field by NHibernate. I've tried adding .CreateCriteria("Price", "StockItemPrice.Price") and the same with CreateAlias, but I get the error NHibernate.QueryException : could not resolve property: Price of: StockItem which makes sense I guess as Price isn't a mapped property. How would I adjust the query to make this possible?

  • Event handler triggered twice instead of once

    - by kwokwai
    Hi all, I am sorry that I have asked two questions in a few minutes. In a html file, I got three child DIV tags in a parent DIV tag: <div id="container"> <div id="frag-123">123</div> <div id="frag-124">124</div> <div id="frag-125">125</div> </div> Now when I click either the three child DIV tags, I will see two alert boxes pop up instead of one: The first alert box will show something like this: frag-123, and the second alert box will show something like this: container I dont know why. I just want to get the ID value of a child DIV, not the one from the parent DIV. <script> $(function() { $("div").click(function() { var imgID = this.id; alert(imgID); }); }); </script> Please help.

  • Populate asp.net MVC Index page with data from the database

    - by Sunil Ramu
    I have a web application in which I need to fetch data from the database and display in the index page. As you know, asp.net mvc has given options to edit delete etc... I need to populate the page using the conventional DB way and it uses a stored procedure to retrieve results. I dont want to use LINQ. This is my model entity class using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace LogMVCApp.Models { public class Property { public int Id { get; set; } public string LogInId { get; set; } public string Username { get; set; } public string Action { get; set; } public string Information { get; set; } public bool Passed{get; set; } public string LogType { get; set; } } } and I need to retrieve data using something like this... var conString = ConfigurationManager.ConnectionStrings["connection"].ToString(); var conn = new SqlConnection(conString); var command = new SqlCommand("LogInsert", conn){CommandType=CommandType.StoredProcedure};

  • need to change TextBox.Text inside TextChanged, something forces form close

    - by Istrebitel
    I am making a TextBox behave like if it could store a null value. In order to do that, i have a variable NullMode that indicates wether the value is stored is Null, and in TextChanged i set that to false, and on specific user action i set it to true and Text to a value that indicates that there is null inside the textbox. Then, based on NullMode, textbox is drawn differently. Now, i have a semaphore-like approach in order to prevent event handle from firing when i dont need it. Here is how it looks: private void input_TextChanged(object sender, EventArgs e) { if (_preventTextBoxEvents) return; _preventTextBoxEvents = true; //if (NullMode) // Text = ""; NullMode = false; ValidateInput(); _preventTextBoxEvents = false; } Now, if i need to set a textbox text to something that should show while in nullmode, i just set _preventTextBoxEvents before i do to true and it works all right. BUT! I need to also remove the text when user tries to input something into the textbox! So i need to set Text to "". Problem is, if i uncomment that, form is closed after the event handler exits. I cannot prevent it (e.Cancel = true in FormClosing doesnt help!) and do not understand what can be causing it. There is no error message too (and i'm not doing try-catch). My logic, when i do Text="". OnTextChanged should fire, it should call my TextChanged and it will see _preventTextBoxEvents is true and exit, so there would be no stack overflow / infinite recursion. What is going on?

  • select option clears when page loads in php

    - by user79685
    Hey guys, the scenario is this: see select below <form name="limit"> <select name="limiter" onChange="limit(this.value)"> <option selected="selected">&nbsp;</option> <option value="5">5</option> <option value="10">10</option> <option value="15">15</option> </select> </form> I want whenever any option is selected for 3 things to happen: 1.) js limit() function is called which all it does its takes current url, adds new query parameter 'limit' with the user selected value eg: http://localhost/blahblah/apps/category.php?pg=1&catId=3021&limit=5 (this will cause the category.php page to be hit and # of product displayed limited to the value selected by user) 2.)Once the url is hit, it reloads but i DONT want the value selected to reset back to the default (which it currently does). I want it to reflect the users selection after page reload. 3.) Also, when i move to the next page (pagination), i would like the state to be carried ova to the next page (ie. remembering the user selection).

  • (Oracle) How get total number of results when using a pagination query?

    - by BestPractices
    I am using Oracle 10g and the following paradigm to get a page of 15 results as a time (so that when the user is looking at page 2 of a search result, they see records 16-30). select * from ( select rownum rnum, a.* from (my_query) a where rownum <= 30 ) where rnum > 15; Right now I'm having to run a separate SQL statement to do a "select count" on "my_query" in order to get the total number of results for my_query (so that I can show it to the user and use it to figure out total number of pages, etc). Is there any way to get the total number of results without doing this via a second query, i.e. by getting it from above query? I've tried adding "max(rownum)", but it doesn't seem to work (I get an error [ORA-01747] that seems to indicate it doesnt like me having the keyword rownum in the group by). My rationale for wanting to get this from the original query rather than doing it in a separate SQL statement is that "my_query" is an expensive query so I'd rather not run it twice (once to get the count, and once to get the page of data) if I dont have to; but whatever solution I can come up with to get the number of results from within a single query (and at the same time get the page of data I need) should not add much if any additional overhead, if possible. Please advise. Here is exactly what I'm trying to do for which I receive an ORA-01747 error because I believe it doesnt like me having ROWNUM in the group by. Note, If there is another solution that doesnt use max(ROWNUM), but something else, that is perfectly fine too. This solution was my first thought as to what might work. SELECT * FROM (SELECT r.*, ROWNUM RNUM, max(ROWNUM) FROM (SELECT t0.ABC_SEQ_ID AS c0, t0.FIRST_NAME, t0.LAST_NAME, t1.SCORE FROM ABC t0, XYZ t1 WHERE (t0.XYZ_ID = 751) AND t0.XYZ_ID = t1.XYZ_ID ORDER BY t0.RANK ASC) r WHERE ROWNUM <= 30 GROUP BY r.*, ROWNUM) WHERE RNUM > 15

  • How to establish a socket connection from iPhone to a Apache server and communicate via PHP?

    - by candoyo
    Hi, I am working on an iPhone game which is depended on a LAMP server. I want to create a "event" based system where the apache server sends an event to the iphone. For this, I am thinking of using "CFStreamCreatePairWithSocketToHost" to connect to port 80 of the apache server. I am able to successfully connect to the server and open a read and write stream via the iPhone, but I am not sure how to send data to the iphone using PHP running from the LAMP server to the iPhone. I think I can use fsockopen in php to open a socket connection and write data to that socket. I tired running this code $fp = fsockopen("tcp://localhost", 80, $errno, $errstr); if (!$fp) { echo "ERROR: $errno - $errstr<br />\n"; } else { echo"writing to socket "; fwrite($fp, "wwqeqweqw eqwe qwe \n"); //echo fread($fp, 26); fclose($fp); echo "done"; } But, I dont see anything being read on the iphone.. Any idea what's going on, or how to accomplish this? Thanks!

  • Dynamic Collapsable Flow Chart Online

    - by Simon
    Been looking through a number of other related posts relating to flowchart software. I have been asked to put together a document outlining some of the typical problems our users encounter with our software product. What I would like to do, is create an interactive/online flowchart that lets users choose from 4-5 overall headings on whats wrong. Then for this to dynamically expand more choices on pinpointing the problem, and so on and so on, until they can get a resolution to their problem. The key thing that I have not been able to find in some of the flowchart software out there, is having the click + expand element. - I dont want all options to appear to the end-user in a huge flow chart as it will distract away from their specific issue. - I want them to be able to click away and go down a specific avenue that will end up giving them some good things to try, based on their decisions/clicks. I was originally thinking of perhaps putting something in Flex or Silverlight (ideally someone would have a template out there) but am now thinking of taking advantage of 3rd party (ideally free) software. This will need to be hosted in a browser. Any ideas?

  • How to create a platform ontop of CSLA? <-- if in case it make sense

    - by Peejay
    Hi all! here is the senario, i'm developing an application using csla 3.8 / c#.net, the application will have different modules. its like an ERP, it will have accounting, daily time record, recruitment etc as modules. Now the requirement is to check for common entities per module and build a "platform" (<- the boss calls it that way) from it. for example, DTR will have an entity "employee", Recruitment will have "Applicant" so one common entity that you can derive from both that can be put in the platform is "Person". "Person" will contain typical info like name, address, contact info etc. I know it sounds like OOP 101. the thing is, i dont know how i am to go about it. how i wish it was just a simple inheritance but the requirement is like to create an API of some sort to be used by the modules using CSLA. in csla you create smart objects right, inheriting from the base classes of csla like businessListbase, readonlylistbase etc. right? what if for example i created a businessbase Applicant class, it will have properties like salary demand, availability date etc. now for the personal info i will need the "Person" from the "platform" and implement it to the applicant class. so in summary i have several questions: how to create such platform? if such platform is possible, how will it be implemented on each module's entities? (im already inheriting from base clases of csla) if incase 1 and 2 are possible, does it have advantages on development and maintenace of the app? the reason why i'm asking #3 is because the way i see it, even if i am able to create a platform for that, i will be needing to define properties of the platform entity on my module entities so to have validation and all. im sorry if i'm typing nonesense i'm really confused. hope someone could enlighten me. thank you all!

  • little java help....

    - by jona
    Hi I am doing some practice problems and trying to print a diagonal line like the example below. I have writen the program you see below and I honestly dont understand what I am doing wrong. I m a java beginner and I cant see how to find the error. Example ( If you only see a straight line of stars...then imagine it diagonally....from top left to bottom right) * * * * * code: class Diagonal{ public static void main(String args[]) { int row, col; for(row = 1; row < 6; row++) { for(col = 1; col <= row; col++) { if(col==row){ System.out.print("*"); } else{ System.out.print(""); } System.out.println(); } } } } I am trying to learn for loops because they really confuse me. Another practice is to print a similar diagonal line but this time from right to left. I cant do that without getting this right however :( I believe they will be pretty similar? Above my reasining is this: As long as the column # is the same as the row number the print the line or otherwise leave a blank....what's wrong with how i did it? THANK YOU!

  • CVS update doesn't fetch most recent commit

    - by mizipzor
    I just commited changes to a file (bringing it to revision 1.3). I then updated the file and to my surprise I got back revision 1.2 (how the file looked before my commit). Checking the history if the file shows that there is a revision 1.3 (most recent) and a 1.2 before that (which is identical to my local copy). Ive tried removing the file and updating the folder, causing the file to be downloaded again. Ive also tried fetching a clean copy of the file of HEAD. Clearing cache and fetching HEAD doesnt work. But forcing an update to revision 1.3 explicitly does. But doing a normal update after that causes it to go back to revision 1.2. This is on a Windows XP machine, server is also a Windows box. Im using TortoiseCVS. Does anyone know what could be causing this? (If you dont know how to fix it, I will award bonus points to anyone that can tell me why CVS broke and, hopefully, how horrible it will be to fix it. I want to add it to my list so that maybe some day I can convince my colleagues to finally give it up in favor of a more modern VCS.)

  • Adding string items to a list of type Person C#

    - by user1862808
    Im makeing a simple registration application and I have an assignment to learn more about lists. I have an assignment that says that i am to create a class called Persons and in that class set the values from the text fields in variables and add this to a list of type Person. So far: in the Person class: string strSocialSecurityNumber = string.Empty;//---( This will not be used now.) string strFirstName = string.Empty; string strLastName = string.Empty; string strFullName = string.Empty; string strAge = string.Empty; string strAll = string.Empty; int intAge = 0; List<Person> lstPerson = new List<Person>(); public void SetValues(string FirstName, string LastName, int Age) { strFirstName = FirstName; strLastName = LastName; strFullName = strFirstName + " " + strLastName; intAge = Age; strAge = Convert.ToString(intAge); strAll = strAge + " " + strFullName; } public List<Person> Person() { lstPerson.Add(strAll); return lstPerson; } Error message: "can not convert from string to Person" The assignment says that the list is to be of the type Person so i am suppose to add strings to it and ive looked how to do this but I dont know how. I have seen that there are options like "ConvertAll" But im not sure if I am allowed to use it since the list should be of type Person. Thank you!

  • Do I really ned bindParam?

    - by sandelius
    Hi there! I'm trying to do a little PDO CRUD to learn some PDO. I have a question about bindParam. Here's my update method right now: public static function update($conditions = array(), $data = array(), $table = '') { self::instance(); // Late static bindings (PHP 5.3) $table = ($table === '') ? self::table() : $table; // Check which data array we want to use $values = (empty($data)) ? self::$_fields : $data; $sql = "UPDATE $table SET "; foreach ($values as $f => $v) { $sql .= "$f = ?, "; } // let's build the conditions self::build_conditions($conditions); // fix our WHERE, AND, OR, LIKE conditions $extra = self::$condition_string; // querystring $sql = rtrim($sql, ', ') . $extra; // let's merge the arrays into on $v_val = array_values($values); $c_val = array_values($conditions); $array = array_merge($v_val, self::$condition_array); $stmt = self::$db->prepare($sql); return $stmt->execute($array); } in my "self::$condition_array" I get all the right values from the ?. SO the query looks like this: UPDATE table SET this = ?, another = ? WHERE title = ? AND time = ? as you can see I dont use bindParams instead I pass the right values in the right order ($array) directly into the execute($array) method. This works like a charm BUT is it safe not use use bindParam here? If not then how can I do it? Thanks from Sweden Tobias

  • Center DIV via jQuery

    - by tony noriega
    I have a footer that is fixed to the bottom of the viewport. I am using jQuery toggle to open a comment card for users to comment and submit: $('a#footer-comment').click(function() { $("#comment-card").toggle(300); return false; $('#comment-card').show({ position:); }); $('a#footer-comment-hide').click(function() { $("#comment-card").toggle(300); return false; $('#comment-card').hide(); }); naturally if i dont add any CSS selectors to #comment-card it shows up UNDER the footer, and out of sight. So i added: {position:absolute; bottom:30px; left:auto;} 30px so it shows up above the footer which is 30px high. Problem is, i can not get this to center in the viewport... if i use pixels, depending on the resolution, it is either too far left or right... how do i center this in the viewport?

  • navigate all items in a wpf tree view

    - by Brian Leahy
    I want to be able to traverse the visual ui tree looking for an element with an ID bound to the visual element's Tag property. I'm wondering how i do this. Controls don't have children to traverse. I started using LogicalTreeHelper.GetChildren, which seems to work as intended, up until i hit a TreeView control... then LogicalTreeHelper.GetChildren doesnt return any children. Note: the purpose is to find the visual UI element that corresponds to the data item. That is, given an ID of the item, Go find the UI element displaying it. Edit: I am apparently am not explaining this well enough. I am binding some data objects to a TreeView control and then wanting to select a specific item programaticly given that business object's ID. I dont see why it's so hard to travers the visual tree and find the element i want, as the data object's ID is in the Tag property of the appropriate visual element. I'm using Mole and I am able to find the UI element with the appropriate ID in it's Tag. I just cannot find the visual element in code. LogicalTreeHelper does not traverse any items in the tree. Neither does ItemContainerGenerator.ContainerFromItem retrieve anything for items in the tree view.

  • Loading/Displaying large amount of data on webpage.

    - by jb
    I have a webpage which contains a table for displaying a large amount of data (on average from 2,000 to 10,000 rows). This page takes a long time to load/render. Which is understandable. The problem is, while the page is loading the PCs memory usage skyrockets (500mb on my test system is in use by iexplorer) and the whole PC grinds to a halt until it has finished, which can take a minute or two. IE hangs until it is complete, switching to another running program is the same. I need to fix this - and ideally i want to accomplish 2 things: 1) Load individual parts of the page seperately. So the page can render initially without the large data table. A loading div will be placed there until it is ready. 2) Dont use up so much memory or local resources while rendering - so at least they can use a different tab/application at the same time. How would I go about doing both or either of these? I'm an applications programmer by trade so i am still a little fizzy on the things I can do in a web environment. Cheers all.

  • multiple clients - one server connection with sockets tcp/ip c# .net

    - by jagse
    Hello guys, I need to develop a client server system where I can have multiple clients communicating with one server at the same time. I want to communicate xml serialized objects and also need to send and receive other commands to invoke methods. Now, I am just starting with socket programming in C# and .Net and found that the asynchronous I/O is the way to go so that the methods dont block the execution of code. Also there are many examples of how to make a simple client server system. So I have a basic understanding of how that works. Anyway, what still is not clear to me is how I can set up a server which can manage connections to multiple clients? Can I just create a new socket per connection and then store those in some kind of list? Do I need some kind of multiplexing to achieve this? Do I have to listen at multiple ports? What`s the best way here? And the other thing is if I need to develop my own protocol to differentiate between what I am actually sending over the network -- xml serialized object or a command which might be just a string encoded in ascII or something. Or would I develop my own protocol just to send these commands? Any kind of help is apreciated! If someone knows a good book which covers this sort of stuff, let me know. Cheers I forgot to mention that some of my clients which are supposed to communicate with my server will be pda and I therefore use the compact framework... So this might bring in some restrictions...

EDIT: Oh i should probably mention, the $lines var is initiated like this: $lines = file('filename.txt'); and inside that file i have formatted like this First1 Last1 First2 Last2 First3 Last3 etc. and i hit delete after each Last name until the next first name is touching, then hit enter to put it on a new line (Editor is notepad++)

  • Why does File.Exists return false?

    - by Jonas Stawski
    I'm querying all images on the Android device as such: string[] columns = { MediaStore.Images.Media.InterfaceConsts.Data, MediaStore.Images.Media.InterfaceConsts.Id }; string orderBy = MediaStore.Images.Media.InterfaceConsts.Id; var imagecursor = ManagedQuery(MediaStore.Images.Media.ExternalContentUri, columns, null, null, orderBy); for (int i = 0; i < this.Count; i++) { imagecursor.MoveToPosition(i); Paths[i]= imagecursor.GetString(dataColumnIndex); Console.WriteLine(Paths[i]); Console.WriteLine(System.IO.File.Exists(Paths[i])); } The problem is that the output shows that some files don't exist. Here's a sample output: /storage/sdcard0/Download/On-Yom-Kippur-Jews-choose-different-shoes-VSETQJ6-x-large.jpg False /storage/sdcard0/Download/397277_10151250943161341_876027377_n.jpg False /storage/sdcard0/Download/Roxy_Cottontail_&_Melo-X_Present..._Some_Bunny_Love's_You.jpg False /storage/sdcard0/Download/album-The-Rolling-Stones-Some-Girls.jpg True /storage/sdcard0/Download/some-people-ust-dont-appreciate-fashion[1].jpg True /storage/sdcard0/Download/express.gif True ... /storage/sdcard0/Download/some-joys-are-expressed-better-in-silence.JPG False How is this possible? I downloaded these images myself from the internet! They should exist in disk.
