  • Python: Cannot concatenate str and NoneType objects

    - by Chase Higgins
    sql = """ INSERT INTO [SCHOOLINFO] VALUES( '""" + self.accountNo + """', '""" + self.altName + """', '""" + self.address1 + """', '""" + self.address2 + """', '""" + self.city + """', '""" + self.state + """', '""" + self.zipCode + """', '""" + self.phone1 + """', '""" + self.phone2 + """', '""" + self.fax + """', '""" + self.contactName + """', '""" + self.contactEmail + """', '""" + self.prize_id + """', '""" + self.shipping + """', '""" + self.chairTempPass + """', '""" + self.studentCount + """' ) """; I have the following code and Python keeps throwing the error that it cannon concatenate strings and nonetype objects. The thing is I have verified every variable here is in fact a string and is not null. I have been stuck on this for quite some time today, and any help would be greatly appreciated.

  • How to get IP address of your application server

    - by Jason
    I need to be able to find the IP address of the server the page is currently executing on. I have some code that calls a third party site and has to pass a specific key that changes depending on which server it is on. Is there a CGI variable or some way in ColdFusion to determine what the IP address is of the host server?

  • Subdomain URL Rewriting and Web Apps

    - by Igor K
    So a lot of web apps have the customer choose their own subdomain, ie mycompany.webapp.com Presumably, every subdomain works off the same set of files and the unique subdomain is perhaps stored as a session object. So how does the URL rewriting work? If someone goes to mycompany.webapp.com, you have to rewrite their unique address to a dynamic page to set the session variable, ie webapp.com/mypage.php?cusomer=mycompany But then when you redirected, you'd be at webapp.com/theappdirectory/ and not mycompany.webapp.com/ So how do they do it?

  • convert file path to string

    - by salvationishere
    I am developing a c# web application with VS 2008 where I am trying to capture the physical path of the selected file. Using IE, I am finally able to retrieve this now in text variable. But I want to capture this information in string. How do I do this? Currently I am using: lb3.Text = Page.Request.PhysicalPath; And it gives me: Text = "C:\Documents and Settings\Admin\My Documents\Visual Studio 2008\Projects\AddFileToSQL\AddFileToSQL\Default.aspx"

  • FileReference.load() not populating FileReference.data.

    - by cookiecaper
    I am trying to use the load method of FileReference object to load the data and use it to display a thumbnail of the selected image. However, after calling fr.load(), fr.data remains null. I'm using Flex Builder 3.0.2 on Windows 7 with Flex SDK 3.4 and Flash Player 10 Debug. If I evaluate fr.load() in Eclipse's watch variables list, I get an error reading "No such variable: load." Anyone know why this is happening?

  • Launch Scala REPL programatically?

    - by David Crawshaw
    I would like to launch a Scala Swing application from the command line, then after the application is started, drop into the Scala REPL to use as a control interface. Ideally I would also like to pre-bind some variable names. Even better would be using a Java2D terminal emulator for the REPL, but I couldn't find anything appropriate. Does the Scala REPL have a public API?

  • Error processing Spree sample images - file not recognized by identify command in paperclip geometry.rb:29

    - by purpletonic
    I'm getting an error when I run the Spree sample data. It occurs when Spree tries to load in the product data, specifically the product images. Here's the error I'm getting: * Execute db:load_file loading ruby <GEM DIR>/sample/lib/tasks/../../db/sample/spree/products.rb -- Processing image: ror_tote.jpeg rake aborted! /var/folders/91/63kgbtds2czgp0skw3f8190r0000gn/T/ror_tote.jpeg20121007-21549-2rktq1 is not recognized by the 'identify' command. <GEM DIR>/paperclip-2.7.1/lib/paperclip/geometry.rb:31:in `from_file' <GEM DIR>/spree/core/app/models/spree/image.rb:35:in `find_dimensions' I've made sure ImageMagick is installed correctly, as previously I was having problems with it. Here's the output I'm getting when running the identify command directly. $ identify Version: ImageMagick 6.7.7-6 2012-10-06 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC Features: OpenCL ... other usage info omitted ... I also used pry with the pry-debugger and put a breakpoint in geometry.rb inside of Paperclip. Here's what that section of geometry.rb looks like: # Uses ImageMagick to determing the dimensions of a file, passed in as either a # File or path. # NOTE: (race cond) Do not reassign the 'file' variable inside this method as it is likely to be # a Tempfile object, which would be eligible for file deletion when no longer referenced. def self.from_file file file_path = file.respond_to?(:path) ? file.path : file raise(Errors::NotIdentifiedByImageMagickError.new("Cannot find the geometry of a file with a blank name")) if file_path.blank? geometry = begin silence_stream(STDERR) do binding.pry Paperclip.run("identify", "-format %wx%h :file", :file => "#{file_path}[0]") end rescue Cocaine::ExitStatusError "" rescue Cocaine::CommandNotFoundError => e raise Errors::CommandNotFoundError.new("Could not run the `identify` command. Please install ImageMagick.") end parse(geometry) || raise(Errors::NotIdentifiedByImageMagickError.new("#{file_path} is not recognized by the 'identify' command.")) end At the point of my binding.pry statement, the file_path variable is set to the following: file_path => "/var/folders/91/63kgbtds2czgp0skw3f8190r0000gn/T/ror_tote.jpeg20121007-22732-1ctl1g1" I've also double checked that this exists, by opening my finder in this directory, and opened it with preview app; and also that the program can run identify by running %x{identify} in pry, and I receive the same version Version: ImageMagick 6.7.7-6 2012-10-06 Q16 as before. Removing the additional digits (is this a timestamp?) after the file extension and running the Paperclip.run command manually in Pry gives me a different error: Cocaine::ExitStatusError: Command 'identify -format %wx%h :file' returned 1. Expected 0 I've also tried manually updating the Paperclip gem in Spree to 3.0.2 and still get the same error. So, I'm not really sure what else to try. Is there still something incorrect with my ImageMagick setup?

  • RRAS with DHCP when the IP pool is on a different subnet

    - by John B
    I run a small business network and the last couple of days I have been setting up some equipment to add VPN capabilities to our network. I've got the following set up: Windows 2008 R2 with RRAS - 172.22.200.50 Cisco RV082 router - 172.22.100.1 / 172.22.200.1 The Cisco router only support DHCP on a single class C network; 172.22.100.0/24. On the Cisco router I have set up an additional subnet; 172.22.200.0/24. The DHCP range is 172.22.100.200-254 When a PPTP connection comes in to the router, it is forwarded to my RRAS at 172.22.200.50. If I configure RRAS to assign IPs from a static pool on the 172.22.200.0/24 subnet everything works fine except the DNS suffix / search domain. However, if I set RRAS to use DHCP I am no longer able to contact any devices on the network. The IP I receive is on a different subnet (172.22.100.0/24). Is it possible to still use DHCP as the method of ip assignment in RRAS, even when the IP adresses assigned are in a different subnet? If yes, what piece of configuration am I missing to fix the VPN connection issues mentioned in the paragraph above. The reason I want RRAS with DHCP to work is because from what I have understood, this is the "only" way to hand out a DNS suffix to VPN clients. Any help on this matter is greatly appreciated!

  • Pass encrypted querystring between php and asp.net (c#)

    - by Paul
    I need to pass a single variable in a querystring from one application (in PHP) to another (in ASP.NET). It's a one way transfer...That is I need to encrypt it in PHP and decrypt it in ASP.NET (c#). I'm barely a newbie on PHP and I'd like not to have to do more than add a tag to the page that needs to do the passing. The data will be anywhere from 5 - 15 characters..only letters and numbers. Thanks!

  • Auto-generating toString Method

    - by Gordon
    Is it good or bad practice auto-generating toString methods for some simple classes? I was thinking of generating something like bellow where it takes the variable names and produces a toString method that prints the name followed by it's value. private String name; private int age; private double height; public String toString(){ Formatter formatter = new Formatter(); return formatter.format("Name: %s, Age: %d, Height %f", name, age, height).toString(); }
