  • How do I validate a RadioButton on MVC?

    - by user54197
    I am using a client side validation and it is starting to get messy, considering I am making a form. With all the textbox and radio button validations, the controller will be overwhelmed. How do I validate and display the error Message for Radio Buttons and multiple textboxes in MVC on the MODEL side? A simplified version of what I have. MODEL... public class ModelData { public string ContactName { get; set; } public string ContactAddress { get; set; } public string ContactPhone { get; set; } public string RadioPoliceFire { get; set; } public string RadioComplaint { get; set; } //The following is a Failure :( public string RadioType { if (RadioType == null) {return "Type Required";} return null; } //End Failure } CONTROLLER... [AcceptVerbs(HttpVerbs.Post)] public ActionResult Info(ModelData InfoData) { if (infoData.RadioType == null) {ModelState.AddModelError("RadioType", "Type Required");} try { ... return RedirectToAction("Confirmation"); catch {ModelState.AddModelError("RadioComplaint", "Error");} }

    - by tiff
    I would like to know how to use session state in a simple log in log out in asp.net mvc.. I have a code here in my controller that I've retrieved from my mysql database for my session log in..but I don't really know how to manipulate it.. <AcceptVerbs(HttpVerbs.Post)> _ Function Index(ByVal username As String, ByVal password As String, ByVal department As String) As ActionResult Dim user As DataTable user = Account.userSelect(username:=username, password:=password, department:=department) If user.Rows.Count = 0 Then Return RedirectToAction("Index", "Home") Else Session("username") = user.Rows(0).Item("username") Session("department") = user.Rows(0).Item("department") Return RedirectToAction("News", "Administration") End If End Function Thank you!

    - by nightingale2k1
    Hi, I need some recommendations ...

I know there are Gavick, it is good ... but I need second options for that 2. thumbnail image for each articles. Joomla has no thumbnail for article modules .. sad :( 3. comment system. should I use Disqus (disqus.com) or using jomcomment. About Disqus, is it good and reliable services ? 4. Tag hierarchy ... any good recommendations ? 5. I hate Joomla Media Manager and Joomla Text Editor (TinyMCE) because I cannot choose directly from media manager (i have to type the full url for images). Any good recommendations ?

  • Theming Drupal Panels

    - by stef
    I created a homepage layout using Panels 3, mostly of blocks created by Views. Now I'd like to apply the visual look and feel as it was designed & sliced. Panels adds an serious amount of divs to its markup. I dont necessarily need to remove this but I do need to add certain classes, id's and change some of the tags used in its markup. What is the best way to go about this?

  • Active X Control issue on Terminal Server 2003

    - by Saif Khan
    I have a security camera system which can be viewed remotely via a web browser. It works excellent only with IE 6 and up and requires an ActiveX control "ERViewer.ocx". Some users require to view the cameras via Windows Terminal Server, but when they try to open the link to the DVR they get the prompt ti install the ActiveX and then the browser crashes when they try to install it. I logged in as admin and got the same issue. I called the tech support of the DVR but they have no idea, in other words, the usual useless tech support. Here is what I get in the error log Faulting application iexplore.exe, version 7.0.6000.16735, faulting module ERViewer.ocx, version 1.6.0.8, fault address 0x000064d7. I am sure it could be some kinda permission getting an ocx to run in IE. What else can I tweak?

  • Associate file extension to application running in XP MODE

    - by V. Romanov
    Hi I'm running a legacy application in XP mode under Win7 Professional. The application installs, runs and publishes fine (appears in win7 start menu by itself after install). However, when I want to associate a file extension from Win7 so that it opens automatically in that application, I don't have it on the list of available applications, and i found no way to add it there. Anyone knows how it can be done? I've read about associating file extensions with remote apps on TS2008, but there it's done by setting the associations in the MSI that is built on the server and used to install the app on the client. Here I have no such tools. Help would be appreciated! Vadim R.

  • Getting Apache to serve same directory with different authentication over SSL?

    - by Lasse V. Karlsen
    I have set up VisualSVN server, a Subversion server that internally uses Apache, to serve my subversion repositories. I've managed to integrate WebSVN into it as well, and just now was able to get it to serve my repositories through WebSVN without having to authenticate, ie. no username or password prompt comes up. This is good. However, with this set up there is apparently no way for me to authenticate to WebSVN at all, which means all my private repositories are now invisible as far as WebSVN goes. I noticed there is a "Listen 81" directive in the .conf file, since I'm running the server on port 81 instead of 80, so I was wondering if I could set up a https:// connection to a different port, that did require authentication? The reason I need access to my private repositories is that I have linked my bug tracking system to the subversion repositories, so if I click a link in the bug tracking system, it will take me to diffs for the relevant files in WebSVN, and some products are in private repositories. Here's my Location section for WebSVN: <Location /websvn/> Options FollowSymLinks SVNListParentPath on SVNParentPath "C:/Repositories/" SVNPathAuthz on AuthName "Subversion Repository" AuthType Basic AuthBasicProvider file AuthUserFile "C:/Repositories/htpasswd" AuthzSVNAccessFile "C:/Repositories/authz" Satisfy Any Require valid-user </Location> Is there any way I can set up a separate section for a different port, say 8100, that does not have the Satisfy Any directive there, which is what enable anonymous access. Note that a different sub-directory on the server is acceptable as well, so /websvn_secure/, if I can make a location section for that and effectively serve the same content only without the Satisfy Any directive, that'd be good too.

  • Windows 7 Sleep Problems

    - by salcan
    My desktop's Windows 7 installation was working perfectly but recently I ran into a problem where it would not come out of sleep. The system seems to be running it's just that it won't come out of the sleep state. If I have to guess I would say that it's not recognizing the USB and thus not waking. I'd say this was a standard problem with Windows not sleeping/hibernating properly, but it was working fine for about a year and stopped working around two weeks ago. I have hybrid sleep ON and USB selective suspend ON.

  • What's the difference between a Table and a Named Range in Excel 2007?

    - by technomalogical
    Can someone explain the difference between Tables and Named Ranges in Excel 2007? It seems that in addition to having the features of Named Ranges, they're somehow marked as Tables which gives them special formatting & filtering options in the ribbon. Other questions: Can I treat a table as a named range? Does a named range provide me any functionality not offered by a table, and vice versa? Should I use one over the other (assuming that consumers of the spreadsheet are using Excel 2007 or higher)? Google has not been helpful (excel difference between named range and table and excel 2007 difference between named range and table) and I've found one resource describing table functionality, but no reference to named ranges.

  • How can I create a heat map based on data from Google Analytics?

    - by tnorthcutt
    How would one go about creating a heat map (say, of the US) based on location data from Google Analytics? I'd like to somehow create such a map with the visitor data from several websites that use Google Analytics. I'm not really looking for a step-by-step tutorial, just some suggestions on how to start. Assume little to no programming experience, but a willingness to learn and hack together stuff to make it work.

Is it possible to send type parameters to object? Or should I change and simply use Otherconstructor

  • Swing Timer in Conjunction with Possible Long-running Background Task

    - by javacavaj
    I need to perform a task repeatedly that affects both GUI-related and non GUI-related objects. One caveat is that no action should performed if the previous task had not completed when the next timer event is fired. My initial thoughts are to use a SwingTimer in conjunction with a javax.swing.SwingWorker object. The general setup would look like this. class { timer = new Timer(speed, this); timer.start(); public void actionPerformed(ActionEvent e) { SwingWorker worker = new SwingWorker() { @Override public ImageIcon[] doInBackground() { // potential long running task } @Override public void done() { // update GUI on event dispatch thread when complete } } } Some potential issues I see with this approach are: 1) Multiple SwingWorkers will be active if a worker has not completed before the next ActionEvent is fired by the timer. 2) A SwingWorker is only designed to be executed once, so holding a reference to the worker and reusing (is not?) a viable option. Is there a better way to achieve this?

  • Writing a script for reading many .csv files with similar filenames

    - by wahalulu
    I have several .csv files with similar filenames except a numeric month (i.e. 03_data.csv, 04_data.csv, 05_data.csv, etc.) that I'd like to read into R. I have two questions: Is there a function in R similar to MATLAB's varname and assignin that will let me create/declare a variable name within a function or loop that will allow me to read the respective .csv file - i.e. 03_data.csv into 03_data data.frame, etc.? I want to write a quick loop to do this because the filenames are similar. As an alternative, is it better to create one dataframe with the first file and then append the rest using a for loop? How would I do that?

  • changing the serialization procedure for a graph of objects (.net framework)

    - by pierusch
    Hello I'm developing a scientific application using .net framework. The application depends heavily upon a large data structure (a tree like structure) that has been serialized using a standard binaryformatter object. The graph structure looks like this: <serializable()>Public class BigObjet inherits list(of smallObject) end class <serializable()>public class smallObject inherits list(of otherSmallerObjects) end class ... The binaryFormatter object does a nice job but it's not optimized at all and the entire data structure reaches around 100Mb on my filesystem. Deserialization works too but it's pretty slow (around 30seconds on my quad core). I've found a nice .dll on codeproject (see "optimizing serialization...") so I wrote a modified version of the classes above overriding the default serialization/deserialization procedure reaching very good results. The problem is this: I can't lose the data previosly serialized with the old version and I'd like to be able to use the new serialization/deserialization method. I have some ideas but I'm pretty sure someone will be able to give me a proper and better advice ! use an "helper" graph of objects who takes care of the entire serialization/deserialization procedure reading data from the old format and converting them into the classes I nedd. This could work but the binaryformatter "needs" to know the types being serialized so........ :( modify the "old" graph to include a modified version of serialization procedure...so I'll be able to deserialize old file and save them with the new format......this doesn't sound too good imho. well any help will be higly highly appreciated :)

  • Calling unmanaged c++ code in C# Mixed with STL

    - by Turtle
    Hey, I want to call unmanaged c++ code in C# The function interface is like following(I simplified it to make it easy to understand) Face genMesh(int param1, int param2); Face is a struct defined as: struct Face{ vector<float> nodes; vector<int> indexs; } I googled and read the MSDN docs found ways to call simple c/c++ unmanged code in C#, also know how to hand the struct as return value. And My question is how to handle "vector". I did not find rules about mapping between vector and some types in C# Thanks!

  • EntityFramework & RowNumber

    Hello. How can I query RowNumber with Entity Framework? For example: var result = data.Users .OrderByDescending("Birthday") .ThenBy("LastName") .ThenBy("FirstName") .Select(u => { RowNumber = ???, u.FirstName, u.LastName }); I want to implement paging for my grid, but I cannot solve problem with finding page with needed user. I'm using EF4.0. Select method with index(http://msdn.microsoft.com/en-us/vcsharp/aa336758.aspx#SelectIndexed) not works with EF. May be there is another way to implement this?

  • Good resources for building web-app in Tapestry

    - by Rich
    Hi, I'm currently researching into Tapestry for my company and trying to decide if I think we can port our pre-existing proprietary web applications to something better. Currently we are running Tomcat and using JSP for our front end backed by our own framework that eventually uses JDBC to connect to an Oracle database. I've gone through the Tapestry tutorial, which was really neat and got me interested, but now I'm faced with what seems to be a common issue of documentation. There are a lot of things I'd need to be sure that I could accomplish with Tapestry before I'd be ready to commit fully to it. Does anyone have any good resources, be it a book or web article or anything else, that go into more detail beyond what the Tapestry tutorial explains? I am also considering integrating with Hibernate, and have read a little bit about Spring too. I'm still having a hard time understanding how Spring would be more useful than cumbersome in tandem with Tapestry,as they seem to have a lot of overlapping features. An example I read seemed to use Spring to interface with Hibernate, and then Tapestry to Spring, but I was under the impression Tapestry integrates to the same degree with Hibernate. The resource I'm speaking of is http://wiki.apache.org/tapestry/Tapstry5First_project_with_Tapestry5,_Spring_and_Hibernate . I was interested because I hadn't found information anywhere else on how to maintain user levels and sessions through a Tapestry application before, but wasn't exactly impressed by the need to use Spring in the example.

  • How to know if the client has terminated in sockets

    - by shadyabhi
    Suppose, I have a connected socket after writing this code.. if ((sd = accept(socket_d, (struct sockaddr *)&client_addr, &alen)) < 0) { perror("accept failed\n"); exit(1); } How can I know at the server side that client has exited.

  • MustOverride Shared Methods in .Net

    Hi I have a few class's that inherit from a base class. I want to enforce that all of these Class's implement a shared method foo(). I am not able to create the following on the base class Public MustOvveride Shared Sub foo() as this is not allowed. I also cant create an Interface that defines a Shared Sub Foo() and implement that in my derrived class's, as this also is not allowed. Does anyone know how i should implement this? p.s i realise my example is in VB and i have also tagged C#, the same problem applies to both languages and presumably the same fix would apply.
