  • Maintaining the query string in ASP.Net MVC

    - by Mantorok
    Hi all Just beginning my journey in ASP.Net MVC and I have a query about something before I dig myself in too deep. I have a table, which is paged, and I have 2 controls above the table: Dropdown that defines order of the results and apply button next to it Textbox that defines a filter and apply button next to it What I need to achieve is that if the user changes the order or adds a filter I fire of an AJAX call to my action like such: /Membership/Users?sort=value&filter=value&page=pagenumber. So my controller action is: // GET Membership/Users?sort=&filter=&page= public ActionResult Users(string sort, string filter, string page) So I have 3 questions: Is this the correct approach? What would be the best way to ensure that the query string is maintained, bearing in mind that the action will nearly always be called by Jquery/Ajax functions? If I wanted to link directly to this action passing the arguments would I need to hard-code the querystring? Thanks

  • quick and dirty client/server communication in Silverlight

    - by Mark
    I'm building a few small prototypes in Silverlight and have quite a bit of .NET experience, but Ive never had the need to contact the server from Silverlight. Im really just after a really quick solution for the purposes of prototyping and I'll be needing to call the server and do a few things, like server a generated image from the server, receive basic responses from the server, but nothing too fancy. Is .NET RIA Services the best way to do this or is it overkill? The documentation for RIA Services is huge, 1 hour long video introductions, 26-part series blogs, etc... seems like its overkill. Is there a quick REST based project I could create, or should RIA services be the way to go?

  • How to make external Mathematica functions interruptible?

    - by Szabolcs
    I had an earlier question about integrating Mathematica with functions written in C++. This is a follow-up question: If the computation takes too long I'd like to be able to abort it using Evaluation Abort Evaluation. Which of the technologies suggested in the answers make it possible to have an interruptible C-based extension function? How can "interruptibility" be implemented on the C side? I need to make my function interruptible in a way which will corrupt neither it, nor the Mathematica kernel (i.e. it should be possible to call the function again from Mathematica after it has been interrupted)

  • Bind a WPF combobox and get selecteditem to a richtextbox

    - by Peter
    Hi, I am using a dataset on the server, in this dataset I have a datatable that calls a stored procedure and returns column names from three tables. I call this stored procedure using a web service. I manage to show all the column names in my combobox but when I want to click a button and insert selected column name into a richtextbox I get System.Data.DataRowView in the textbox instead. My code: 'the combobox 'if I don't have this textblock all the values are shown vertical instead of the normal horizontal lines 'the stored procedure SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE (TABLE_NAME = 'Customer') OR (TABLE_NAME = 'Invoices') OR (TABLE_NAME = 'Orders') 'the button Private Sub btnAddColumnNames_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles btnAddColumnNames.Click ' Add column names to the richtextbox Dim tr As New TextRange(rtbText.Selection.Start, rtbText.Selection.End) tr.Text = cboColumnNames.SelectedItem.ToString() rtbText.Focus() End Sub Any suggestions on how to get the selected text in the combobox to the richtextbox? Any help is appreciated.

  • xslt dropdown problems

    - by Primetime
    I have a page with two drop down boxes created in a xslt. I am using onchange in both blocks to call a javascript function. If both drop downs are loaded on the page only the first drop down has a working onchange. I checked the view source code and it shows both onchange events. Does anyone have any idea how to fix this? ex: two drop downs, select first one, it refreshes, select second it does nothing, select first one and it still refreshes. code removed.

  • Require Integer Value not Memory Address whilst avoiding Invalid receiver type compiler warning

    - by Dave Anderson
    I have the following code; int days = [[SettingsUtils daysToRetainHistory] intValue]; [retainHistory setText:[NSString stringWithFormat:@"Days to retain History: %d", days]]; [daysToRetainHistory setValue:days animated:NO]; where [SettingsUtils daysToRetainHistory] is as follows; + (int) daysToRetainHistory { return (int)[[NSUserDefaults standardUserDefaults] objectForKey:@"CaseBaseDaysToRetainHistory"]; } I get the compiler warning Invalid receiver type 'int' because I call intValue on an int but unless I do this I can't seem to get the integer value out and always end up with the memory address i.e. 98765432 instead of 9 which ruins the UILabel display [retainHistory] and the UISlider [daysToRetainHistory] value. How do I avoid the compiler warning and still get my integer value in the label and the necessary float value for setting the UISlider value?

  • Getting Different IP each time

    - by Sarfraz
    Hello, I am creating a poll script for a facebook fan page: http://www.facebook.com/apps/application.php?id=115400635147687&v=app_115400635147687 I am getting the IP using: $_SERVER['REMOTE_ADDR'] But the problem is that each time I refresh the page, or make an ajax call, the IP is changed everytime. Someone told me that facebook has many IPs, proxies. Basically I need to save the IP in database, so that once a user from certain IP has voted, he should not be able to do so again. What is the solution or alternative to this?

  • Excel - referenced values via OleDB from .Net client

    - by ho
    I'm trying to read an Excel file (.xls, I think Excel 2003 compatible) via OleDB, but it fails to get the values for referenced fields. This is my current test code (please note, this is just part of the class): Private m_conn As OleDbConnection Public Sub New(ByVal fileName As String) Dim connString As String = String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=Excel 8.0;", fileName) m_conn = New OleDbConnection(connString) m_conn.Open() End Sub Public Sub GetSheet(ByVal sheet As String) Dim query As String = String.Format("SELECT * FROM [{0}]", sheet) Using cmd As OleDbCommand = m_conn.CreateCommand() cmd.CommandText = query Dim ds As New DataSet() Dim a As New OleDbDataAdapter(cmd) Using rdr As OleDbDataReader = cmd.ExecuteReader() While rdr.Read() Debug.WriteLine(rdr.Item(0).ToString()) End While End Using End Using End Sub But if the value is a reference (something like =+'MySheetName'!K37), I just get a DBNull from the call to rdr.Item(0). I can get around this by automating Excel instead, but would prefer not to have to use Excel automation so wondering if anyone knows how to do it.

  • Activator.CreateInstance with type name as string and including parameters

    - by Kelly
    I am working in .Net 3.5, looking at all the various constructors for Activator.CreateInstance. I want to create an instance of a class, calling a particular constructor. I do not have the class type, only its name. I have the following, which works, but actually winds up calling the parameterless constructor first, then the one I want. This is not a terribly big deal, but the parameterless constructor calls a rather busy base constructor, and the constructor I want to call does, too. In other words, given a type, calling CreateInstance with parameters is easy (only the last two lines below), but given only a type name, is there a better way than this? ObjectHandle oh = Activator.CreateInstance( "MyDllName", "MyNS." + "MyClassName" ); object o = oh.Unwrap( ); object newObj = Activator.CreateInstance( o.GetType( ), new object[] { param1 } ); return ( IMyDesiredObject )newObject; Thanks!

  • ASP Classic Named Parameter in Paramaterized Query: Must declare the scalar variable

    - by My Alter Ego
    I'm trying to write a parameterized query in ASP Classic, and it's starting to feel like i'm beating my head against a wall. I'm getting the following error: Must declare the scalar variable "@something". I would swear that is what the hello line does, but maybe i'm missing something... <% OPTION EXPLICIT %> <!-- #include file="../common/adovbs.inc" --> <% Response.Buffer=false dim conn,connectionString,cmd,sql,rs,parm connectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Data Source=.\sqlexpress;Initial Catalog=stuff" set conn = server.CreateObject("adodb.connection") conn.Open(connectionString) set cmd = server.CreateObject("adodb.command") set cmd.ActiveConnection = conn cmd.CommandType = adCmdText cmd.CommandText = "select @something" cmd.NamedParameters = true cmd.Prepared = true set parm = cmd.CreateParameter("@something",advarchar,adParamInput,255,"Hello") call cmd.Parameters.append(parm) set rs = cmd.Execute if not rs.eof then Response.Write rs(0) end if %>

  • Android WebView not respecting scaling percentage on physical devices...

    - by fiXedd
    I have a WebView which I'm trying to have scale to a certain percent on loading the page. The iPhone version of this software uses the HTML meta-tag: <meta name="viewport" content="width=320, initial-scale=0.95, maximum-scale=2.0, user-scalable=1"> Since Android's WebView doesn't seem to respect that tag I hard-coded the percent using setInitialScale(). However, the WebView is just flat-out ignoring this method call. No matter what number I put in there it shows at 100%. Ideas? Update: It's working fine in the emulator, it's only failing on my Droid (Motorola) and my G1 (HTC).

  • How can I change what happens when "enter" key is pressed on a DataGridView?

    - by SO give me back my rep
    when I am editing a cell and press enter the next row is automatically selected, I want to stay with the current row... I want to happen nothing except the EndEdit. I have this: private void dtgProductos_CellEndEdit(object sender, DataGridViewCellEventArgs e) { dtgProductos[e.ColumnIndex, e.RowIndex].Selected = true; //this line is not working var index = dtgProductos.SelectedRows[0].Cells.IndexOf(dtgProductos.SelectedRows[0].Cells[e.ColumnIndex]); switch (index) { case 2: { dtgProductos.SelectedRows[0].Cells[4].Selected = true; dtgProductos.BeginEdit(true); } break; case 4: { dtgProductos.SelectedRows[0].Cells[5].Selected = true; dtgProductos.BeginEdit(true); } break; case 5: { btnAddProduct.Focus(); } break; default: break; } } so when I edit a row that is not the last one I get this error: Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.

  • Environment variable (NLS_LANG) value altered in Java process?

    - by Ralkie
    This was noticed in some legacy Java application (jre1.4 on HP-UX). Parent process (shell script S1) is starting Java process, which on its own is starting child process (shell script S2). Schematically it's: S1 Java S2. NB! Java application connects to Oracle DB using OCI driver. What is strange here is that process running S1 has environment variable NLS_LANG set to american_america.BLT8MSWIN1257, Java spawns S2 using: Runtime.getRuntime().exec(cmd); and S2 shows that NLS_LANG is set to american_america.UTF8 (!) This happens on some limited-access environment (production), I was not able to reproduce same problem on linux with jre 1.5. AFAIK, Java process should inherit environment from its parrent (S1) and should pass all environment variables to its child S2 (since single argument exec call was used). However, it does not seem to be the case. Any ideas why NLS_LANG appears to be altered?

  • Is there any framework for Windows Forms, DB driven application development/prototyping?

    - by dolzenko
    I'm writing simple database driven application, 80% of functionality is CRUD operations on about 15 tables. Coming from web development background I figured I can cover almost all of these CRUD cases with Rails scaffolding or say Django admins. So I started to look around for Rails/Django-like framework but for Windows Forms applications (ofcourse I understand that "rich client" application development significantly differs from a web development and I'm not expecting anything really similar). I was surprised that except for a variety of ORMs (let's call it Model-layer) it seems like I'm left with little choice when it comes to View-Controller layer. Maybe I'm missing something? PS. I evaluated Visual Studio DataSet Designer, but it seems to work only for the most simple cases, and requires additional code for any slightly nontrivial task. (added) so far I've found: TrueView for .NET (thanks to Vijay Patel) NConstruct

  • If .net sha1 hash expects a byte array, and php sha1() wants a string, can I match the results?

    - by lynn
    I have a set of bytes I want to apply an sha1 hash to. One hash will be in .net, the other in PHP. Then I'll test to see if they match. In .net, you can create a byte array and use sha.ComputeHash(). byte[] data = new byte[DATA_SIZE]; byte[] result; SHA1 sha = new SHA1CryptoServiceProvider(); // This is one implementation of the abstract class SHA1. result = sha.ComputeHash(data); In PHP, you call sha1($string). I can't do anything about the .net side of the code, but how can I get the same hash out of PHP that .net will generate? Please note: I am ONLY able to work on the PHP side of this. The .net stuff is fixed and can't be modified. Thanks!

  • How to set background image in Java?

    - by Dew
    I am developing a simple platform game using Java using BlueJ as the IDE. Right now I have player/enemy sprites, platforms and other items in the game drawn using polygons and simple shapes. Eventually I hope to replace them with actual images. For now I would like to know what is the simplest solution to setting an image (either URL or from local source) as the 'background' of my game window/canvas? I would appreciate it if it isn't something long or complex as my programming skills aren't very good and I want to keep my program as simple as possible. Kindly provide example codes with comments to elaborate on their function, and also if it's in its own class, how to call on relevant methods used by it on other classes. Thank you very much.

  • jQuery Ajax: Copy - Paste thingy

    - by tsiger
    Hi everyone, I have a form where a check an input field for its value and then i do an Ajax call using the typewatch plugin ( a small little thing which detects that the user has stopped typing after a predefined interval ). It works great. As this field is a "coupon discount" in an order form, the value could be entered by copy pasting the "coupon code" from an email or something. It also works with Ctrl+C - Ctrl+V for Copy and paste but not when a user selects the text with the mouse, clicks copy from the context menu and then paste from this menu. Is there a way in jQuery to check for this kind of behaviour in jQuery somehow?

  • Basic class returns onject reference instead of Array

    - by php-b-grader
    I have very basic class: class Customer { protected $id; protected $customer; public function __construct($customer_id) { $this->id = $customer_id; return $this->set_customer(); } protected function set_customer() { $query = mysql_query("SELECT * FROM customer WHERE id = '$this->id'"); $this->customer = mysql_fetch_row($query); return $this->customer; } } $customer = new Customer($order->customer->id); print_r($customer); This is not doing what I want it to but I understand why... $customer returns a reference to the Customer Object... But what I want is the MySQL row array from the mysql_fetch_row() call... What am I missing?

  • customise jQuery totemticker plugin

    - by Don
    I'm using the totemticker jQuery plugin, but need to be able to stop it programatically. It doesn't seem to provide this feature, so I had a look at the source code to see if I could add it myself. It seems that all I need to do is figure out how to call base.stop_interval() However, I can't seem to make the object that is stored in base accessible to callers. I've made a couple of unsuccesful atttempts, but hopefully someone who knows a bit more about how jQuery plugins work can point me in the right direction.

  • compile error: The import xxxx cannot be resolved

    - by Zachary
    I am developing a Java project using Eclipse. The project uses another project called engine, which I have added in my project build-path. As I need to call a dabo class, called House, in one of my project class, named Window, I have used the following code as usual: import ee.asus.kernel.House; I got however the following error in compiling time: Exception in thread "main" java.lang.Error: Unresolved compilation problems: The import ee cannot be resolved House cannot be resolved to a type House cannot be resolved to a type House cannot be resolved to a type at main.ee.asus.GUI.FrameWindow.Window.<init>(Window.java:10) at main.ee.asus.GUI.StartApplication.main(StartApplication.java:13) It's worth to point out that my prject and the dabo project use the same directory/packages names. Does anyone have a clue where the error may be?

  • Can't inherit from auto_str without problems

    - by fret
    What I want to do is this: #include <memory> class autostr : public std::auto_ptr<char> { public: autostr(char *a) : std::auto_ptr<char>(a) {} autostr(autostr &a) : std::auto_ptr<char>(a) {} // define a bunch of string utils here... }; autostr test(char a) { return autostr(new char(a)); } void main(int args, char **arg) { autostr asd = test('b'); return 0; } (I actually have a copy of the auto_ptr class that handles arrays as well, but the same error applies to the stl one) The compile error using GCC 4.3.0 is: main.cpp:152: error: no matching function for call to `autostr::autostr(autostr)' main.cpp:147: note: candidates are: autostr::autostr(autostr&) main.cpp:146: note: autostr::autostr(char*) I don't understand why it's not matching the autostr argument as a valid parameter to autostr(autostr&).

  • Relvance of 'public' contructor in abstract class.

    - by Amby
    Is there any relevance of a 'public' constructor in an abstract class? I can not think of any possible way to use it, in that case shouldn't it be treated as error by compiler (C#, not sure if other languages allow that). Sample Code: internal abstract class Vehicle { public Vehicle() { } } The C# compiler allows this code to compile, while there is no way i can call this contructor from the outside world. It can be called from derived classes only. So shouldn't it allow 'protected' and 'private' modifiers only. Please comment.

  • Any good way to set the exit status of a Cocoa application?

    - by buglesareking
    I have a Cocoa app which interacts with a server and displays a GUI. If there is a fatal error, I display an alert and exit. I'd like to set the exit status to a non-zero value to reflect that an error occurred, for ease of interaction with some other UNIX based tools. Unfortunately I've been unable to find a good way to do so - NSApplication doesn't seem to have any way to set an exit status. At the moment, I've subclassed NSApplication and added an exitStatus ivar (which I set in my app delegate when necessary), then overridden -terminate: so that it calls exit(exitStatus). This works fine, but it seems a bit grungy to me, not to mention that I may be missing something important that the stadnard `terminate: is doing behind the scenes. I can't call [super terminate:sender] in my subclassed method, because that exit()s without giving me a chance to set the status. Am I missing something obvious?
