  • ASP.NET MVC Route based on Web Browser/Device (e.g. iPhone)

    - by Alex
    Is it possible, from within ASP.NET MVC, to route to different controllers or actions based on the accessing device/browser? I'm thinking of setting up alternative actions and views for some parts of my website in case it is accessed from the iPhone, to optimize display and functionality of it. I don't want to create a completely separate project for the iPhone though as the majority of the site is fine on any device. Any idea on how to do this?

  • How to discover web servers on a local network?

    - by Stefan Kendall
    Suppose I'm running several servers serving basic requests on my local network (say a home network, where all machines generally have an IP in the form K.K.K.x, where x is variable). Is there an easy way to discover all such servers? I would need to find each IP on the network running a particular java server application.

  • How can I make an Access database readable from the web while it is open in MS Access?

    - by djdilicious
    I have a website using ASP with an MS Access DB back-end for storing mainly blog posts. My company has a very long software approval process so I am stuck with what I have (i.e. I must use Access). I use server-side javascript to retrieve posts stored in the database using OLEDB calls. Everything works fine except that I cannot read any tables from the database when it is open in the MS Access program. The page displays an error message about the file being in use. This could lead to significant downtime while I am doing any work within Access. How can I make the file readable by my ASP application while it is open in Access?

  • perl : Passing hash , array through socket program betwen client and server

    - by pavun_cool
    Hi All . In sockets I have written the client server program . First I tried to send the normal string among them it sends fine . After that I am trying to send the hash and array values from client to server and server to client . When I printing the values using Dumper . It is giving me only reference . What Should I do for getting accessing the actual values in client server . Server Program: use IO::Socket; use strict; use warnings; my %hash = ( "name" => "pavunkumar " , "age" => 20 ) ; my $new = \%hash ; #Turn on System variable for Buffering output $| = 1; # Creating a a new socket my $socket= IO::Socket::INET->new(LocalPort=>5000,Proto=>'tcp',Localhost => 'localhost','Listen' => 5 , 'Reuse' => 1 ); die "could not create $! \n" unless ( $socket ); print "\nUDPServer Waiting port 5000\n"; my $new_sock = $socket->accept(); my $host = $new_sock->peerhost(); while(<$new_sock>) { #my $line = <$new_sock>; print Dumper "$host $_"; print $new_sock $new . "\n"; } print "$host is closed \n" ; Client Program use IO::Socket; use Data::Dumper ; use warnings ; use strict ; my %hash = ( "file" =>"log.txt" , size => "1000kb") ; my $ref = \%hash ; # This client for connecting the specified below address and port # INET function will create the socket file and establish the connection with # server my $port = shift || 5000 ; my $host = shift || 'localhost'; my $recv_data ; my $send_data; my $socket = new IO::Socket::INET ( PeerAddr => $host , PeerPort => $port , Proto => 'tcp', ) or die "Couldn't connect to Server\n"; while (1) { my $line = <stdin> ; print $socket $ref."\n"; if ( $line = <$socket> ) { print Dumper $line ; } else { print "Server is closed \n"; last ; } } I have given my sample program about what I am doing , Can any one tell me what I am doing wrong in this code.

  • Why jquery have problem with onbeforeprint event?

    - by Cesar Lopez
    Hi all, I have the following function. $(function() { $(".sectionHeader:gt(0)").click(function() { $(this).next(".fieldset").slideToggle("fast"); }); $("img[alt='minimize']").click(function(e) { $(this).closest("table").next(".fieldset").slideUp("fast"); e.stopPropagation(); return false; }); $("img[alt='maximize']").click(function(e) { $(this).closest("table").next(".fieldset").slideDown("fast"); e.stopPropagation(); return false; }); }); <script type="text/javascript"> window.onbeforeprint = expandAll; function expandAll(){ $(".fieldset:gt(0)").slideDown("fast"); } </script> For this html <table class="sectionHeader" ><tr ><td>Heading 1</td></tr></table> <div style="display:none;" class="fieldset">Content 1</div> <table class="sectionHeader" ><tr ><td>Heading 2</td></tr></table> <div style="display:none;" class="fieldset">Content 2</div> I have several div class="fieldset" over the page, but when I do print preview or print, I can see all divs sliding down before opening the print preview or printing but on the actual print preview or print out they are all collapse. I would appreciate if anyone comes with a solution for this. Anyone have any idea why is this or how to fix it? Thanks. PS:Using a does not work either ( I assume because jquery using toggle) and its not the kind of question I am looking for.

  • Speed up a web service for auto complete and avoid too many method calls.

    - by jphenow
    So I've got my jquery autocomplete 'working,' but its a little fidgety since I call the webservice method each time a keydown() fires so I get lots of methods hanging and sometimes to get the "auto" to work I have to type it out and backspace a bit because i'm assuming it got its return value a little slow. I've limited the query results to 8 to mininmize time. Is there anything i can do to make this a little snappier? This thing seems near useless if I don't get it a little more responsive. javascript $("#clientAutoNames").keydown(function () { $.ajax({ type: "POST", url: "WebService.asmx/LoadData", data: "{'input':" + JSON.stringify($("#clientAutoNames").val()) + "}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (data) { if (data.d != null) { var serviceScript = data.d; } $("#autoNames").html(serviceScript); $('#clientAutoNames').autocomplete({ minLength: 2, source: autoNames, delay: 100, focus: function (event, ui) { $('#project').val(ui.item.label); return false; }, select: function (event, ui) { $('#clientAutoNames').val(ui.item.label); $('#projectid').val(ui.item.value); $('#project-description').html(ui.item.desc); pkey = $('#project-id').val; return false; } }) .data("autocomplete")._renderItem = function (ul, item) { return $("<li></li>") .data("item.autocomplete", item) .append("<a>" + item.label + "<br>" + item.desc + "</a>") .appendTo(ul); } } }); }); WebService.asmx <WebMethod()> _ Public Function LoadData(ByVal input As String) As String Dim result As String = "<script>var autoNames = [" Dim sqlOut As Data.SqlClient.SqlDataReader Dim connstring As String = *Datasource* Dim strSql As String = "SELECT TOP 2 * FROM v_Clients WHERE (SearchName Like '" + input + "%') ORDER BY SearchName" Dim cnn As Data.SqlClient.SqlConnection = New Data.SqlClient.SqlConnection(connstring) Dim cmd As Data.SqlClient.SqlCommand = New Data.SqlClient.SqlCommand(strSql, cnn) cnn.Open() sqlOut = cmd.ExecuteReader() Dim c As Integer = 0 While sqlOut.Read() result = result + "{" result = result + "value: '" + sqlOut("ContactID").ToString() + "'," result = result + "label: '" + sqlOut("SearchName").ToString() + "'," 'result = result + "desc: '" + title + " from " + company + "'," result = result + "}," End While result = result + "];</script>" sqlOut.Close() cnn.Close() Return result End Function I'm sure I'm just going about this slightly wrong or not doing a better balance of calls or something. Greatly appreciated!

  • How to fire off a asych thread in a web application, and gaurantee only 1 thread fires?

    - by Blankman
    I want to cache a object in memory. Regenerating the object when the cache expires is fairly expensive, so I want to do the following: When the cache is "about" to expire, I want to fire off a asychronous thread that will go and rebuild the object and then reset the cache. One thing I am worry about is multiple threads firing to fetch the object to cache, I only want a single thread doing this, realizing many people will be hitting the website. This might not be the best use case to do this, but I want to know how to do this sort of thing.

  • Problem overridding virtual function

    - by William
    Okay, I'm writing a game that has a vector of a pairent class (enemy) that s going to be filled with children classes (goomba, koopa, boss1) and I need to make it so when I call update it calls the childclasses respective update. I have managed to create a example of my problem. #include <stdio.h> class A{ public: virtual void print(){printf("Hello from A");} }; class B : public A{ public: void print(){printf("Hello from B");} }; int main(){ A ab = B(); ab.print(); while(true){} } Output wanted: "Hello from B" Output got: "Hello from A" How do I get it to call B's print function?

  • Fix for Visual Studio 2005 not showing filename or line on errors in web pages when compiling?

    - by spoulson
    A project I'm on requires Visual Studio 2005. One annoyance is that when a website project in the solution, any compile errors from .aspx or .ascx files show up like: (0,0): warning CS0168: The variable 'ex' is declared but never used (0,0): warning CS0162: Unreachable code detected (0,0): warning CS0168: The variable 'ex' is declared but never used (0,0): warning CS0168: The variable 'ex' is declared but never used How can I track these down? Is there an option I'm missing that gives me filename and line numbers?

  • Why can't I handle a KeyboardInterrupt in python?

    - by Josh
    I'm writing python 2.6.6 code on windows that looks like this: try: dostuff() except KeyboardInterrupt: print "Interrupted!" except: print "Some other exception?" finally: print "cleaning up...." print "done." dostuff() is a function that loops forever, reading a line at a time from an input stream and acting on it. I want to be able to stop it and clean up when I hit ctrl-c. What's happening instead is that the code under except KeyboardInterrupt: isn't running at all. The only thing that gets printed is "cleaning up...", and then a traceback is printed that looks like this: Traceback (most recent call last): File "filename.py", line 119, in <module> print 'cleaning up...' KeyboardInterrupt So, exception handling code is NOT running, and the traceback claims that a KeyboardInterrupt occurred during the finally clause, which doesn't make sense because hitting ctrl-c is what caused that part to run in the first place! Even the generic except: clause isn't running. EDIT: Based on the comments, I replaced the contents of the try: block with sys.stdin.read(). The problem still occurs exactly as described, with the first line of the finally: block running and then printing the same traceback.

  • How can I get the fully qualified name of an assembly from it's basic name?

    - by GenericTypeTea
    I'm currently writing a custom forms application that allows a user to design a data capture form. I store the field's ControlType and ControlAssembly in the database and then create them on the forms at runtime. For example: ControlType = `System.Web.UI.WebControls.TextBox`. ControlAssembly= `System.Web`. So I can therefor create a fully qualified name and create the control doing the following: string target = Assembly.CreateQualifiedName("System.Web", field.ControlType); Type type = Type.GetType(target); Control control = Activator.CreateInstance(type) as Control; But, this will cause an error as "System.Web" is not a valid assembly name. The assembly name itself has to be fully qualified, i.e. System.Web.Extensions would be: "System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Is there any way I can get the fully qualified name of the assembly System.Web without having to store the entirity of the version, culture and PKT?

    This is more a question of pros/cons between PHP and JAVA. Iv been doing research, and iv narrowed it down to those two. And in consideration, id like to go into mobile app dev...So thats +1 for Java. Time taken to learn the language is not an issue...Just would like to know which is the most profitable at the end of all the training. And on a slight note. Can Javascript work with Java? And what is the real advantage of that?
