• transfer data from Excel to SQL Server

  - by Jason

  I have an Excel Spreadsheet that contains all my data that I need to put into an SQL Server database. I am fairly new o ASP.NET and have never had to export from Excel to SQL Server before. My Excel spreadsheets looks like this Trade Heading - ArtID - BusinessName - AdStyleCode - Address - Suburb In SQL Server I have created a table named "Listings" which is in this format intListingID - intCategoryID - BusinessName - ArtID - intAdCode -Address - Suburb What would be the best way to export the data from Excel and then import it into SQLServer 2005. Thanks...

• How can I trigger a transition effect when a child control is added or removed in flex?

  - by Jason Towne

  I've got a custom component that has children components dynamically added and removed to it depending on what button the user clicks. What I would like to do is trigger a transition effect that moves the child component onto the stage when it's added and then moves it off when it's removed. Does anyone have a good example on how to accomplish this? Edit: I figured it out and left my solution below. I hope it helps someone else!

• How do I write a scheme macro that defines a variable and also gets the name of that variable as a s

  - by Jason Baker

  This is mostly a follow-up to this question. I decided to just keep YAGNI in mind and created a global variable (libpython). I set it to #f initially, then set! it when init is called. I added a function that should handle checking if that value has been initialized: (define (get-cpyfunc name type) (lambda args (if libpython (apply (get-ffi-obj name libpython type) args) (error "Call init before using any Python C functions")))) So now here's what I want to do. I want to define a macro that will take the following: (define-cpyfunc Py_Initialize (_fun -> _void)) And convert it into this: (define Py_Initialize (get-cpyfunc "Py_Initialize" (_fun -> _void))) I've been reading through the macro documentation to try figuring this out, but I can't seem to figure out a way to make it work. Can anyone help me with this (or at least give me a general idea of what the macro would look like)? Or is there a way to do this without macros?

• Deploy to web container, bundle web container or embed web container...

  - by Jason

  I am developing an application that needs to be as simple as possible to install for the end user. While the end users will likely be experience Linux users (or sales engineers), they don't really know anything about Tomcat, Jetty, etc, nor do I think they should. So I see 3 ways to deploy our applications. I should also state that this is the first app that I have had to deploy that had a web interface, so I haven't really faced this question before. First is to deploy the application into an existing web container. Since we only deploy to Suse or RedHat this seems easy enough to do. However, we're not big on the idea of multiple apps running in one web container. It makes it harder to take down just one app. The next option is to just bundle Tomcat or Jetty and have the startup/shutdown scripts launch our bundled web container. Or 3rd, embed.. This will probably provide the same user experience as the second option. I'm curious what others do when faced with this problem to make it as fool proof as possible on the end user. I've almost ruled out deploying into an existing web container as we often like to set per application resource limits and CPU affinity, which I believe would affect all apps deployed into a web container/app server and not just a specific application. Thank you.

• scons: overriding build options for one file

  - by Jason S

  Easy question but I don't know the answer. Let's say I have a scons build where my CCFLAGS includes -O1. I have one file needsOptimization.cpp where I would like to override the -O1 with -O2 instead. How could I do this in scons? update: this is what I ended up doing based on bialix's answer: in my SConscript file: Import('env'); env2 = env.Clone(); env2.Append(CCFLAGS=Split('-O2 --asm_listing')); sourceFiles = ['main.cpp','pwm3phase.cpp']; sourceFiles2 = ['serialencoder.cpp','uartTestObject.cpp']; objectFiles = []; objectFiles.append(env.Object(sourceFiles)); objectFiles.append(env2.Object(sourceFiles2)); ... previously this file was: Import('env'); sourceFiles = ['main.cpp','pwm3phase.cpp','serialencoder.cpp','uartTestObject.cpp']; objectFiles = env.Object(sourceFiles); ...

• Control Javascript > CSS through Flash

  - by Jason b.

  Hi All, Ideal situation/setup: A page containing 1 Flash movie and a separate div containing a few hyperlinks. These hyperlinks each have a unique class name like so: Copy code <ul> <li><a href="" class="randomname1"></a></li> <li><a href="" class="randomname2"></a></li> <li><a href="" class="randomname3"></a></li> <li><a href="" class="randomname4"></a></li> </ul> The Flash movie itself will contain 4 buttons. Clicking on one of these buttons should make the Flash communicate with Jquery/JS and tell it to highlight the specific classname. Ideas so far For the javascript, it would look like $(function() { function setClass(className) {$("."+className).css("background","red");} }); And in specific keyframes within Flash 1. button 1 ExternalInterface.call("setClass","randomname1"); 1. button 2 ExternalInterface.call("setClass","randomname2"); 1. button 3 ExternalInterface.call("setClass","randomname3"); 1. button 4 ExternalInterface.call("setClass","randomname4"); The problem is that it is not really working well and i am not sure if i am making Flash communicate with JS properly. Any ideas or hints to steer me in the right direction again? Thank you in advance J.

• HTTP request stream not readable outside of request handler

  - by Jason Young

  I'm writing a fairly complicated multi-node proxy, and at one point I need to handle an HTTP request, but read from that request outside of the "http.Server" callback (I need to read from the request data and line it up with a different response at a different time). The problem is, the stream is no longer readable. Below is some simple code to reproduce the issue. Is this normal, or a bug? function startServer() { http.Server(function (req, res) { req.pause(); checkRequestReadable(req); setTimeout(function() { checkRequestReadable(req); }, 1000); setTimeout(function() { res.end(); }, 1100); }).listen(1337); console.log('Server running on port 1337'); } function checkRequestReadable(req) { //The request is not readable here! console.log('Request writable? ' + req.readable); } startServer();

• CakePHP Routing Alias, no prefix

  - by Jason McCreary

  I have a dashboard with a series of widgets. Per specification, the widgets need to be buried under a /widgets/ directory. So I have added the following to my routes.php Router::connect('/widget/:controller/:action/*', array()); But I seem to be running into trouble on widgets/links/ and widgets/links/view/1 I am new to CakePHP, but this doesn't seem all that impressive. I have yet to find anything in the Book or by search. So any help is appreciated. Thanks.

• Selecting a Function Value Shows nvarchar(4000) on an Index

  - by Jason N. Gaylord

  I have a view that I'm trying to setup an Index for. One of the select columns for the view executes a user-defined function that has a return value of varchar(250). However, when I try to setup an Index on that column, I see a size of nvarchar(4000). Why is that and will that cause a problem if I continue to setup my index?

• Need a push in the write direction, to write my first functional test in Rails?

  - by Jason

  Hi, I've read quiet a bit of documentation over the last few days about testing in Rails, I'm sitting down to write my first real test and not 100% sure how to tie what I have learned together to achieve the following functional test (testing a controller) I need to send a GET request to a URL and pass 3 parameters (simple web-service), if the functionality works the keyword "true" is simply returned, otherwise the keyword "false" is returned - its in only value returned & not contained in any , or other tags. The test should assert that if "true" is returned the test is successful. This is probably very simple so apologies for such a non-challenging question. If anyone could point me in the write direction on how I can get started, particularly how I can test the response, I'd be very grateful! Thanks!

• UML and Documenting Simple Diagrams

  - by Jason

  As part of a rewrite of an old Java application into C#, I'm writing an actual Software Design Specification. A problem I run into is when a method is too simple to bother with a Sequence Diagram (it doesn't interact with other objects). As an example, I have a simple POJO called Item, containing the following method: public String getCategoryKey() { StringBuffer value = new StringBuffer("s-"); value.append(this.getModelID()); value.append("-c"); return value; } The purpose and the algorithm for the method needs to be documented. However, a sequence diagram is overkill. How would others document it? (I take no credit/blame for the given method, it's very old code and the author "forgot" to put their name in the Javadoc).

• How can I ignore properties of a component using Fluent Nhibernate's AutoPersistenceModel?

  - by Jason

  I am using Fluent NHibernate AutoMappings to map my entities, including a few component objects. One of the component objects includes a property like the following: public string Value { set _value = value; } This causes an NHibernate.PropertyNotFoundException: "Could not find a getter for property 'Value'..." I want to ignore this property. I tried creating an IAutoMappingOverride for the component class but I couldn't use AutoMapping<.IgnoreProperty(x = x.Value) for the same reason. "The property or indexer 'MyComponent.Value' cannot be used in this context because it lacks the get accessor" I've also looked at IComponentConvention but can't see anyway of altering the mappings with this convention. Any help would be appreciated... Thanks

• CakePHP hasAndBelongsToMany (HABTM) Delete Joining Record

  - by Jason McCreary

  I have a HABTM relationship between Users and Locations. Both Models have the appropriate $hasAndBelongsToMany variable set. When I managing User Locations, I want to delete the association between the User and Location, but not the Location. Clearly this Location could belong to other users. I would expect the following code to delete just the join table record provided the HABTM associations, but it deleted both records. $this->Weather->deleteAll(array('Weather.id' => $this->data['weather_ids'], false); However, I am new to CakePHP, so I am sure I am missing something. I have tried setting cascade to false and changing the Model order with User, User-Weather, Weather-User. No luck. Thanks in advance for any help.

• IE 8 prompts user on "slow" jQuery script

  - by Jason

  I have a form with over 100 list items that I must reorder on submit. The following code works to reorder my list without any apparent problems in Firefox; however, IE prompts with the message "A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive. Do you want to abort the script?" If the user clicks 'No', the script will work as expected. var listitems = $(form).find('li').get(); listitems.sort(function(a, b) { var compA = $(a).attr('id'); var compB = $(b).attr('id'); return (compA - compB); }); Any ideas on how to make this more efficient?

• Saving a form using autocomplete instead of select field

  - by Jason Swett

  I have a form that looks like this: <%= form_for(@appointment) do |f| %> <% if @appointment.errors.any? %> <div id="error_explanation"> <h2><%= pluralize(@appointment.errors.count, "error") %> prohibited this appointment from being saved:</h2> <ul> <% @appointment.errors.full_messages.each do |msg| %> <li><%= msg %></li> <% end %> </ul> </div> <% end %> <%= f.fields_for @client do |client_form| %> <div class="field"> <%= client_form.label :name, "Client Name" %><br /> <%= client_form.text_field :name %> </div> <% end %> As you can see, the field for @client is a text field as opposed to select field. When I try to save my form, I get this error: Client(#23852094658120) expected, got ActiveSupport::HashWithIndifferentAccess(#23852079773520) That's not surprising. It seems to me that it was expecting a select field, which it could translate into a Client object, but instead it just got a string. I know I can do Client.find( :first, :conditions => { :name => params[:name] } ) to find a Client with that name, but how do I tell my form that that's what's going on?

• PHP namespaces and using the \ prefix in declaration

  - by Jason McCreary

  The following throws an error stating Exception can no be redeclared. namespace \NYTD\ReadingListBackend; class Exception extends \Exception { } However, removing the \ prefix in the namespace declaration does not: namespace NYTD\ReadingListBackend; I recently adopted PHP namespaces. My understanding is that namespaces prefixed with \ are a fully qualified name. So why can't I use the prefix in the namespace declaration? I can when referencing (e.g. new \NYTD\ReadingListBackend\Exception). Would appreciate a full explanation as I couldn't find anything in the docs.

• PHP Include and sort by variable within file

  - by Jason Hoax

  I have written this PHP include-script but now I'm trying to sort the included files out by variables WITHIN the included php's. In other words, in each included PHP file there is a rating, now I want the ratings to be read so that when they are included they will be sorted out from highest to lowest. (scores are like 6.0 to 9.0) Kind Regards! $location = 'experiments/visualizations'; foreach (glob("$location/*.php") as $filename) { include $filename; } The included files are named randomly like: File1: $filename = "AAAA"; $projecttitle = "Project Name"; $description = "This totally explains the product"; $score = "7.6"; File 2: $filename = "BBBB"; $projecttitle = "Project Name2" $description = "This totally explains the product"; $score = "9.6"; As you can see 9.6 is higher than 7.6 but PHP sorts the includes out by name instead of variables within the file. I tried sorting, but I can't get it fixed. Help!

• How can the number of modifications be changed in the TeamCity success email?

  - by Jason Slocomb

  I would like to list an arbitrary number of changes rather than the default 10 that are listed now. We have a dev build on checkin where this isn't necessary, but the once daily build that goes out I would like to have all the changes listed for the day. If that is unpossible (range?) than the last n would be fine. I've looked in the .ftl files, specifically common.ftl. It contains the macro for using data from jetbrains.buildServer.notification.impl.ChangesBean to acquire the changes. I am hopeful there is a way to set properties externally that ChangesBean will look at, but I haven't been able to discover anything. Ideas?

• What programming languages are good for statistics?

  - by Jason Baker

  I'm doing a bit more statistical analysis on some things lately, and I'm curious if there are any programming languages that are particularly good for this purpose. I know about R, but I'd kind of prefer something a bit more general-purpose (or is R pretty general-purpose?). What suggestions do you guys have? Are there any languages out there whose syntax/semantics are particularly oriented towards this? Or are there any languages that have exceptionally good libraries?

• Is there any way to use GUIDs in django?

  - by Jason Baker

  I have a couple of tables that are joined by GUIDs in SQL Server. Now, I've found a few custom fields to add support for GUIDs in django, but I tend to shy away from using code in blog posts if at all possible. I'm not going to do anything with the GUID other than join on it and maybe assign a GUID on new entries (although this is optional). Is there any way to allow this using django's built-in types? Like can I use some kind of char field or binary field and "trick" django into joining using it? If it's any help, I'm using django-pyodbc.
