  • Clean way to assign value unless empty

    - by atmorell
    Hello, I often need to assign a variable, if the source value is set. So far I have done it like this: filters[:red] = params[:search][:red] unless params[:search][:red].nil? This works but looks a bit clumsy. There must be a more DRY way of getting this result. Any suggestions? Best regards. Asbjørn Morell.

    - by JohnW
    Our WCF svc files contain the following: <%@ ServiceHost Service="Foo" Factory="Bar" Language="C#" Debug="true" %> What does debug=true mean in this case? web.config has debug=false, but I don't know what this one means and can't find a reference on MSDN.

  • extract variables from an expression using javascript regexp

    - by powerboy
    For example, here is a string representing an expression: var str = 'total = sum(price * qty) * 1.09875'; I want to extract variables (i.e., 'total', 'price' and 'qty' but not 'sum' since 'sum' is a function name) from this expression. What is the regexp pattern in javascript? Variable name consists of letters, digits, or the underscore, beginning with letters or the underscore.

  • In google app engine, how to iterate through form fields (python, wsgiref.handlers)

    - by MarcoB
    Using python and wsgiref.handlers, I can get a single variable from a form with self.handler.request.get(var_name), but how do I iterate through all form variables, be they from GET and POST? Is it something like this? for field in self.handler.request.fields: value = self.handler.request.get(field) Again, it should include both fields included in the POST and fields from the query string, as in a GET request. Thanks in advance folks...

  • Align 2 sets of 2D point clouds

    - by user108088
    From what I gather, there are two major methods to perform alignment on point clouds, Iterative Closest Point (ICP) and Particle Filtering. What are the advantages of each method? And can someone point me some good tutorials. For what I am currently doing, I think ICP would be easier, I can't seem to find any simple reference implementations online for 2d point sets. Has anyone seen (psuedo)code for ICP with details on the transformation step? Thanks in advance.

    Hi all, I have a variable of type List<RelationHeader>. Now I want to copy all the elements in this list to a new list, but I want to actually copy all the members by value (clone them). Is there a quick command to do this, or do I need to iterate over the list and copy them one at a time?

  • c++ meaning of the use of const in the signature

    - by jbu
    Please help me understand the following signature: err_type funcName(const Type& buffer) const; so for the first const, does that mean the contents of Type cannot change or that the reference cannot change? secondly, what does the second const mean? I don't really even have a hint. Thanks in advance, jbu

  • Javascript Alert Return value / Event

    - by Chris
    Hey, The question is pretty simple, but i'm not the big AJAX/JS coder, so I have no clue if it's possible. Is there any way that I can check whether or not an alert() was executed on a remote site? Like if I inputted an alert("Welcome to this site"); through a get variable, is there any way to check if it that alert() was actually executed in the browser? And not necessarily through AJAX/JS.

  • How do I properly register the Type Library of A VB.NET COM+ Component?

    - by k_Dank
    I am looking to upgrade legacy VB6 COM+ components to VB.NET components. I have seemingly upgraded one already, called EventPackage, which has one class, IEventListener. Another, TradeOrders, Implements EventPackage.IEventListener. When attempting to build TradeOrders, I get the following Errors/Warnings; Cannot load type library for reference "EventPackage". Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED)) The referenced component 'EventPackage' could not be found. Type 'EventPackage.IEventListener' is not defined. In the .vbproj, I notice this reference <COMReference Include="EventPackage"> <Guid>{0D76C094-21A6-4E04-802B-6E539F7102D7}</Guid> <Lcid>0</Lcid> <VersionMajor>2</VersionMajor> <VersionMinor>0</VersionMinor> <WrapperTool>tlbimp</WrapperTool> </COMReference> When I search the registry for this Guid, I find nothing. When using GUIDs for similar COM+ objects, I find them in HKEY_CLASSES_ROOT\CLSID\{...}\TypeLib ("..." being the GUID of the other component). When I go to the registry key name corresponding to EventPackage.IEventListener, I find that there is no \TypeLib subkey. As you might suspect, searching the reg for "0D76C094-21A6-4E04-802B-6E539F7102D7" yields no results. So I know this must be a registry problem, But I have tried seemingly every google result I have found. I have tried Regasm and regsvcs .exe's to no avail. Many pages just tell me that dragging the dll to the COM+ manager should automatically register the component. So how do I register the Type library? Details on how I made EventPackage COM+ component Ran the VB6-VB.NET wizard Then I added some lines to the assemblyinfo.vb file added Imports System.EnterpriseServices added Imports System.EnterpriseServices Imports System.Data.SqlClient <Assembly: CLSCompliant(True)> <Assembly: AssemblyKeyFileAttribute("...")> for a strong name <Assembly: Guid("...")> (Where "..." is the COM+ CLSID of the old component) I added the following to the class file IEventListener.VB Imports System.EnterpriseServices <ComClass("...")> _ (Where ... is the proper COM+ CLSID, that is the only argument) Inherits ServicedComponent changed the ID made by the Conversion wizard to the proper value (from <System.Runtime.InteropServices.ProgId("IEventListener_NET.IEventListener)> to <System.Runtime.InteropServices.ProgId("EventPackage.IEventListener")> _ Then I dragged the DLL into the COM+ manager in the proper COM+ application (although, the "Path" is not specified and only says mscoree.dll)

  • Hacking "Contact Form 7" code to Add A "Referred By" field

    - by Scott B
    I've got about 6 subdomains that have a "contact us" link and I'm sending all these links to a single form that uses "Contact Form 7". I add ?from=site-name to each of the links so that I can set a $referredFrom variable in the contact form. The only two things I'm missing are (1) the ability to insert this referredFrom variable into the email that I get whenever someone submits the form and (2) The ability to redirect the user back to the site they came from (stored in $referredFrom) Any ideas? Here's a bit of code from includes/classes.php that I thought might be part of the email insert but its not doing much... function mail() { global $referrer; $refferedfrom = $referrer; //HERE IS MY CUSTOM CODE $fes = $this->form_scan_shortcode(); foreach ( $fes as $fe ) { $name = $fe['name']; $pipes = $fe['pipes']; if ( empty( $name ) ) continue; $value = $_POST[$name]; if ( WPCF7_USE_PIPE && is_a( $pipes, 'WPCF7_Pipes' ) && ! $pipes->zero() ) { if ( is_array( $value) ) { $new_value = array(); foreach ( $value as $v ) { $new_value[] = $pipes->do_pipe( $v ); } $value = $new_value; } else { $value = $pipes->do_pipe( $value ); } } $this->posted_data[$name] = $value; $this->posted_data[$refferedfrom] = $referrer; //HERE IS MY CUSTOM CODE } I'm also thinking that I could insert the referredFrom code somewhere in this function as well... function compose_and_send_mail( $mail_template ) { $regex = '/\[\s*([a-zA-Z][0-9a-zA-Z:._-]*)\s*\]/'; $callback = array( &$this, 'mail_callback' ); $mail_subject = preg_replace_callback( $regex, $callback, $mail_template['subject'] ); $mail_sender = preg_replace_callback( $regex, $callback, $mail_template['sender'] ); $mail_body = preg_replace_callback( $regex, $callback, $mail_template['body'] ); $mail_recipient = preg_replace_callback( $regex, $callback, $mail_template['recipient'] ); $mail_headers = "From: $mail_sender\n"; if ( $mail_template['use_html'] ) $mail_headers .= "Content-Type: text/html\n"; $mail_additional_headers = preg_replace_callback( $regex, $callback, $mail_template['additional_headers'] ); $mail_headers .= trim( $mail_additional_headers ) . "\n"; if ( $this->uploaded_files ) { $for_this_mail = array(); foreach ( $this->uploaded_files as $name => $path ) { if ( false === strpos( $mail_template['attachments'], "[${name}]" ) ) continue; $for_this_mail[] = $path; } return @wp_mail( $mail_recipient, $mail_subject, $mail_body, $mail_headers, $for_this_mail ); } else { return @wp_mail( $mail_recipient, $mail_subject, $mail_body, $mail_headers ); } }
