  • Joomla contact form doesn't pass W3C validation

    - by aramaz
    Hi, I get the following error when I try to validate a contact page on my site: document type does not allow element "script" here The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed). One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error). I am using Joomla 1.5.7, and the doctype is <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Any idea how to fix this?

  • htaccess: how to prevent infinite subdirectories?

    - by Vincent Isles
    My .htaccess at the root directory contains this: Options -MultiViews +FollowSymlinks -Indexes ErrorDocument 404 /404.htm RewriteEngine On RewriteBase / followed by a bunch of RewriteRules. The .htaccess at the /forum subdirectory contains this: RewriteEngine On RewriteBase /forum RewriteRule ^index.html$ index.php [L,NE] RewriteRule ^(.*)-t-([0-9]+).html(.*)$ showthread.php?tid=$2$3 [QSA,L] RewriteRule ^(.*)-t-([0-9]+)-([0-9]+).html$ showthread.php?tid=$2&page=$3 [QSA,L] followed by other rules mapping SEO-friendly URLs to the true URLs. mydomain.com/forum/a-thread-t-1.html returns the page showthread.php?tid=1 but so does mydomain.com/forum/forum/a-thread-t-1.html, mydomain.com/forum/forum/forum/a-thread-t-1.html and so on. I don't want this behavior - I want pages accessed as /forum/forum/* to return a 404. Any hint on where I had been wrong?

  • Using stored procedures to generate RDLC report in C#

    - by NDraskovic
    I'm making an application that generates reports for my client. I'm using his database that contains stored procedures which return the data needed for the reports. The problem is that I don't know how to execute them from the application (more specific the TableAdapter in my dataset). When I use the visual aid to create the TableAdapter, it shows the error "Invalid object named #table1". This is weird because there is a temporary table called #table1 in the stored procedure. When I try to do the whole job programmatically, I get the exception Incorrect syntax near '.'. An object or column name is missing or empty. For SELECT INTO statements, verify each column has a name. For other statements, look for empty alias names. Aliases defined as "" or [] are not allowed. Change the alias to a valid name. I created a DataTable that has identical structure as the result of the stored procedure, but I still get the same exception

  • Which file is the COM++ object and how do I import it to .NET?

    - by Bad Man
    I'm trying to write a COM++ object wrapper around a Qt widget (control) I wrote so I can use it in future .NET projects. e.g.: public __gc class comWidget; In the compile directory are the .exe, an exe.intermediate.manifest, and the comWidget.obj, and also some other crap files (.pdb, etc). So what/how do I import into .NET? I feel like I'm missing an important step for registering the object or whatever, but all these tutorials are terrible outdated and ridiculously unhelpful (for instance, I'm using the old CLR syntax because I can't find any good docs on the new stuff, thx again M$ for being lazy faggots as usual)

  • improve my jquery validation plugin code

    - by Jared
    Hi All Just hoping soemone can help me to write better code than I can come up with on my own. I am using the jquery validation plugin. I have some fields that are mandatory ONLY if certain options are chosen. The below code works fine. But the thing is, is that that my list of 'OR's is much longer than I've put here. and it needs to be applied not just to 'directorsName' but a whole long list of inputs, selects etc. My question is.. how can I wrap up the code contained inside the RETURN? (so I dont have to keep repeating my 'OR's. I'm guessign I need a function but I'm unsure of the syntax) $("#myForm").validate({ rules: { directorsName : { required: function(element) { return ( $('#account_for').val() == "Joint" || $('#directors_number').val() == "2" || $('#directors_number').val() == "3" ); } } } }); Thanks in advance

  • How do I remotely obtain a system's network shares and connections?

    - by Mick
    I'm looking for a way to obtain information similar to the following console applications, remotely: net use net share netstat -ano However, I need to be able to do this without running a 3rd party application on the system. This effectively rules out using psexec to execute the command remotely, because psexec would then be installed as a service. I should add that I have administrative credentials on the remote system. I've considered using WMI's remote execution ability, but that requires me to write output to a file and then retrieve it. It's possible, but I'd like to know if anyone has a better way. I am using Delphi 2010.

  • ASP.NET/VB/SQL: trying to insert data, getting error "no value given for required parameters"

    - by Sara
    I am pretty sure this is a basic syntax error, I am new at this and basically figuring things out by trial and error... I am trying to insert data from textboxes into an Access database, where the primary key fields in tableCourse are prefix and course_number. It keeps giving me the "no value given for one or more required parameters" error. Here is my codebehind: Protected Sub Wizard1_FinishButtonClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.FinishButtonClick 'Collect Data Dim myDept = txtDept.Text Dim myFirst = txtFirstName.Text Dim myLast = txtLastName.Text Dim myPrefix = txtCoursePrefix.Text Dim myNum = txtCourseNum.Text 'Define Connection Dim myConn As New OleDbConnection myConn.ConnectionString = AccessDataSource1.ConnectionString 'Create commands Dim myIns1 As New OleDbCommand("INSERT INTO tableCourse (department, name_first, name_last, prefix, course_number) VALUES (@myDept, @myFirst, @myLast, @myPrefix, @myNum)", myConn) 'Execute the commands myConn.Open() myIns1.ExecuteNonQuery() End Sub

  • Ruby on Rails- :symbols, @iVars and "strings" - oh my!

    - by Meltemi
    New to Rails and trying to get my head around when/why to use :symbols, @ivars , "strings" within the framework. I think I understand the differences between them conceptually only one :symbol instance per project one @ivar per instance multiple "strings" - as they are created whenever referenced (?) Feel free to correct me! The main confusion comes from understanding the rules & conventions of what Rails expects - where and WHY? I'm sure there's an "Ah ha!" moment coming but I haven't had it yet...as it seems pretty arbitrary to me (coming from C/Obj-C). -thx

  • How do I get the output of an Xcode user script to auto indent?

    - by John Gallagher
    The Problem I want to press a key when I have a line highlighted and convert from a single line: JGLogEntry *logEntry = [JGLogEntry applicationNoWindowsFrom:date1 to:date2 intoMOC:mockRawMOC]; to a multiline statement: JGLogEntry *logEntry = [JGLogEntry applicationNoWindowsFrom:date1 to:date2 intoMOC:mockRawMOC]; What I've Tried I've got a simple ruby script that almost gets me there. #!/usr/bin/env ruby s = STDIN.read s.gsub!(/(:.+?\w) (\w.+?)/,'\1' + "\n\t" +'\2') print s When I set the output to "Replace Selection", I get this: JGLogEntry *logEntry = [JGLogEntry applicationNoWindowsFrom:date1 to:date2 intoMOC:mockRawMOC]; When I set the output to "Place on Clipboard", then paste it in, I get the desired result: JGLogEntry *logEntry = [JGLogEntry applicationNoWindowsFrom:date1 to:date2 intoMOC:mockRawMOC]; However, this is two keypresses which is clumsy. Any ideas how I can get the replaced text to obey Xcode's auto indent rules?

  • How can I print N array elements with delimiters per line?

    - by Mark B
    I have an array in Perl I want to print with space delimiters between each element, except every 10th element which should be newline delimited. There aren't any spaces in the elements if that matters. I've written a function to do it with for and a counter, but I wondered if there's a better/shorter/canonical Perl way, perhaps a special join syntax or similar. My function to illustrate: sub PrintArrayWithNewlines { my $counter = 0; my $newlineIndex = shift @_; foreach my $item (@_) { ++$counter; print "$item"; if($counter == $newlineIndex) { $counter = 0; print "\n"; } else { print " "; } } }

  • rails - form to disply non-input type fields in nested form

    - by nktokyo
    Hi, I guess this is a newbie question, but what is the syntax in a form to show contents of fields not as a text box/area, but rather like label would appear. <% form_for @user do |f| %> <% f.fields_for :user_ingreds do |builder| %> <p> <%= builder.??? %> </p> <% end %> <% end%> user has many user_ingreds and accepts_nested_attributes for user_ingreds. Basically I want to make a list of user_ingreds where the user can't edit the data but can remove the record from the list via a button - however the fields_for builder doesn't recognize a direct call to to the fields in user_ingreds model (ie, builder.user_id throws and error.

  • Why does s ++ t not lead to a stack overflow for large s?

    - by martingw
    I'm wondering why Prelude> head $ reverse $ [1..10000000] ++ [99] 99 does not lead to a stack overflow error. The ++ in the prelude seems straight forward and non-tail-recursive: (++) :: [a] -> [a] -> [a] (++) [] ys = ys (++) (x:xs) ys = x : xs ++ ys So just with this, it should run into a stack overflow, right? So I figure it probably has something to do with the ghc magic that follows the definition of ++: {-# RULES "++" [~1] forall xs ys. xs ++ ys = augment (\c n -> foldr c n xs) ys #-} Is that what helps avoiding the stack overflow? Could someone provide some hint for what's going on in this piece of code?

  • Why Do Programmers Get So Invested in their Favorite Technologies?

    - by Pierreten
    I've noticed this culture surrounding Ruby where developers truly believe that they are somehow more gifted than developers of other languages, regardless of experience and talent (even when that isn't the case, I've met some extremely junior Ruby developers come up with some pretty basic constructs, and pass them off as some sort of revolutionary idea). The derision of strongly typed languages seems to be a common theme as well; regardless of its merits. Is there something particular to the Ruby syntax in general that is to account for this? Is there a sociological component to it?

  • jQuery blockUI and AJAX POST

    - by oompahloompah
    I am using jQuery BlockUI in a project. For a particular user action, I want to block the UI, and then POST data to the server. When the timeout event occurs OR the server returns, I want to unblock the page. I can't seem to implement this behaviour. This is what I have so far (not working) $(document).ready(function(){ $('#test').click(function(event){ $.blockUI({ message: $('#syntax-chk') }); $.ajax({ type: 'POST', url: 'www.example.com', data: somedata, dataType: "json" }); setTimeout(function() { $.unblockUI({ onUnblock: function(){ alert('onUnblock'); } }); }, 2000); }); can anyone spot what I may be doing wrong?

  • Using PowerShell class to invoke a "[namespace.class]::method" style command

    - by Marco
    Hello, I created a powershell object via .net to invoke commands. When I invoke normal commands like 'Get-Process' I had no problems: ps.AddCommand("Get-Process").AddParameter(...).Invoke() but I'm not able to invoke a .net method with the syntax "[namespace.class]::method", just to make an example to invoke [System.IO.File]::Exists("c:\boo.txt"). I tried with ps.AddCommand("[System.IO.File]::Exists(\"c:\\boo.txt\")").Invoke() ps.AddCommand("[System.IO.File]::Exists").AddArgument("c:\\boo.txt").Invoke() and some others. It always throws an exception which says that the command specified is not recognized. There is a way to invoke that type of command? Thanks

  • Suggested C++ books?

    - by Josh Bradley
    Ok, I've had one semester of C++ and will be taking a second semester in it after I have taken a Data Structure class this fall. In the first class, we dealt mainly with C++ syntax and the textbook we used was ok, but now I'm wanting to go ahead and purchase a great C++ book that encompasses a lot of the programming concepts used today. I'm learning Objective-C on my own and was able to get through the whole object-oriented stuff pretty easily, along with other things like pointers, inheritance, delegation, etc. It doesn't have to exactly have EVERYTHING in it, but I do want to buy the book with the most information in it. Money is no problem. So my question is what book did you use or still use for C++? Is it a book that you can reference back to if you ever forget how to do something small, or would you have to go online and find the answer.

  • Accessing a nested hash in a controller

    - by Magicked
    I have the following (snipped) parameters passed into my controller. Parameters: {"commit"=>"OK", "action"=>"set_incident_incident_status_id", "id"=>"1", "controller"=>"incidents", "incident"=>{"incident_status_id"=>"1"}} I know that if I want to select the incident, I can do: @incident = Incident.find(params[:id]) How do I access the "incident"={"incident_status_id"="1"}? I thought to try something like: @incident_status = IncidentStatus.find(params[:incident => :incident_status_id]) But that didn't work. I'm assuming it's just a syntax problem at this point, and I haven't found a solution yet. Any help would be much appreciated!

  • When to rewrite vs. upgrade?

    - by MrGumbe
    All custom legacy software needs changing, or so say our users. Sometimes they want a feature or two added and all that is necessary to change a bit of code, add a control, or some other minor upgrade task. Sometimes they want to ditch their error-prone VB5 desktop solution and rewrite the whole thing as a rich Web 2.0 ASP.NET MVC application. More often, however, the scope of changes to legacy functionality lies somewhere between these two extremes. What rules of thumb to you use to decide whether you should upgrade an existing application or start from scratch?

  • Semantic errors

    - by gautam kumar
    Can semantic errors be detected by the compiler or not? If not when do the errors get detected? As far as I know semantic errors are those errors which result from the expressions involving operators with incorrect number/type of operands. For example: n3=n1*n2;//n1 is integer, n2 is a string, n3 is an integer The above statement is semantically incorrect. But while reading C Primer Plus by Stephen Prata I found the following statement The compiler does not detect semantic errors, because they don't violate C rules. The compiler has no way of divining your true intentions. That leaves it to you to find these kinds of errors. One way is to compare what a program does to what you expected it to do. If not the compiler, who detects those errors? Am I missing something?
