• Prevent Python from caching the imported modules

  - by Olivier

  While developing a largeish project (split in several files and folders) in Python with IPython, I run into the trouble of cached imported modules. The problem is that instructions import module only reads the module once, even if that module has changed! So each time I change something in my package, I have to quit and restart IPython. Painful. Is there any way to properly force reloading some modules? Or, better, to somehow prevent Python from caching them? I tried several approaches, but none works. In particular I run into really, really weird bugs, like some modules or variables mysteriously becoming equal to None... The only sensible resource I found is Reloading Python modules, from pyunit, but I have not checked it. I would like something like that. A good alternative would be for IPython to restart, or restart the Python interpreter somehow. So, if you develop in Python, what solution have you found to this problem?

• How to filter the jqGrid data NOT using the built in search/filter box

  - by Jimbo

  I want users to be able to filter grid data without using the intrinsic search box. I have created two input fields for date (from and to) and now need to tell the grid to adopt this as its filter and then to request new data. Forging a server request for grid data (bypassing the grid) and setting the grid's data to be the response data wont work - because as soon as the user tries to re-order the results or change the page etc. the grid will request new data from the server using a blank filter. I cant seem to find grid API to achieve this - does anyone have any ideas? Thanks.

• Does GoDaddy supports RESTful services via WCF

  - by Amir Naor

  After deploying a WCF RESTful service that i created using the REST started kit, i got several errors that i managed to solve following this post: http://www.edoverip.com/edoverip/index.php/2009/01/30/running-wcf-on-godaddy Now i'm stuck with this error: IIS specified authentication schemes 'Basic, Anonymous', but the binding only supports specification of exactly one authentication scheme. Valid authentication schemes are Digest, Negotiate, NTLM, Basic, or Anonymous. Change the IIS settings so that only a single authentication scheme is used I saw that others got to this point without a solution. GoDaddy support dont know nothing. Is it possible at all? Are there any web hosting services that you know that support that?

• Using custom std::set comparator

  - by Omry

  I am trying to change the default order of the items in a set of integers to be lexicographic instead of numeric, and I can't get the following to compile with g++: file.cpp: bool lex_compare(const int64_t &a, const int64_t &b) { stringstream s1,s2; s1 << a; s2 << b; return s1.str() < s2.str(); } void foo() { set<int64_t, lex_compare> > s; s.insert(1); ... } I get the following error: error: type/value mismatch at argument 2 in template parameter list for ‘template<class _Key, class _Compare, class _Alloc> class std::set’ error: expected a type, got ‘lex_compare’ what am I doing wrong?

• jQuery input mask length

  - by Tim

  Hey all, I have an input field and I want to limit it to alphanumerical (A-Z, a-z, 0-9) characters only, with a MINIMUM field length of 5, and a maximum length of up to 15 characters total. Does anyone know how I can do this using jQuery? I'm trying to use the jQuery input mask by digitalBush - http://digitalbush.com/projects/masked-input-plugin/ The problem is that UNLESS I enter 15 characters, the field goes blank. If I enter "012345678912345" (15 characters) in the input field then the value is stored and it's fine. But if I enter "12345" as a username, when that input box loses focus its value goes back to being blank. Is there something that I can change in the "definitions" or options somewhere that fixes this? Many thanks for your help :) Tim

• iphone - UITapGestureRecognizer problem

  - by Mike

  I have two UIImageViews one as subview of the other. The subview is smaller and is centered on the screen. Both have UITapGestureRecognizer assigned and both were intended to respond to single taps. A single tap on the main view (= the area outside the subview) is fine, but a tap inside the subview is seen as the main view as a tap too. How can I have this to work independently? both views have setCancelsTouchesInView and setDelaysTouchesEnded set to NO and both have the same delegate (yes, I need to have the same delegate and cannot change that). How may I force the main view to ignore any tap on the area that belongs to its subview? thanks for any help.

• Question on MVVM pattern on WPF ?

  - by Ashish Ashu

  I have a user control let say UC1 . This user control have viewmodel UC1_vm. In the usercontrol UC1 I have a canvas in which drawing curve logic is implemented. This drawing curve logic is based on the data points property in the view model ( UC1_vm). The data points property inside the view model change with different condition. The generation of data points is written in the View Model. I want to bind the data points property in the view model to the draw curve logic inside the User control (view). I want whenever the data point property is changed in the view model , the canvas calls the draw curve method. Can I set the set any property of canvas which when changed it calls the on paint logic auto matically? Please suggest me the approach of implementing this scenario!!

• AutoCompleteExtender - authentication failure (forms authentication)

  - by Paddy

  I'm using the AutoCompleteExtender from the AJAX control toolkit on my aspx page - I have it wired up to a WCF service that is returning a string array and everything works happily. If I change my service definition to include a demand for the caller to be authenticated, like so: <OperationContract(), PrincipalPermission(SecurityAction.Demand, Authenticated:=True)> _ Public Function GetLookupValues(ByVal prefixText As String, ByVal count As Integer, ByVal contextKey As String) As String() Then the autocomplete extender stops working, and I get an authentication error in the service. The service is set up to use ASPNetCompatibility mode, and I was hoping that the extender would pass the authentication credentials for my logged in user - does anyone know how to make this work?

• UIWebView frame resize does not resize the inner content...

  - by Markus Gömmel

  Hi, if I change the frame of a UIWebView (scalesPageToFit property is YES), what do I have to do that the zooming level of a currently displayed webpage persists? Let's say I have a UIWebView frame with a width of 200 pixels, and has zoomed into a website so that only one column is visible. After changing the width to 300, I still see the column with the same size, and additional space at the left and right. But what I would need is that I still only see this column, but bigger. Any ideas what I have to do to achive this? I tried a lot of things, but nothing worked so far. By the way, the iPhone built in Safari browser does exactly this thing (with the same website, so it's not content related) when rotating the iPhone... I see the same content, bug bigger, NOT more content as it happens with my current version of code. Thanks for helping! Markus

• Silverlight DataStateBehavior, initial value not used

  - by JimmySavile

  Hi, I am trying to use the Silverlight DataStateBehavior, it works fine in most cases where I click a button which sets say a 'Selected' Property in the view model to either false or true. The DataStateBehavior then tells the VisualStateManager to go to the relevant state. Like this: <Button...> <i:Interaction.Behaviors> <id:DataStateBehavior Binding="{Binding Selected}" Value="True" TrueState="SelectedVisualState" FalseState="DeselectedVisualState"/> </i:Interaction.Behaviors> </Button> The above works fine. What I am trying to do though is to get it to set the correct state when the application loads, if I were to set the 'Selected' property on the view model to true by default I wouldn't see any changes in the UI until I clicked the button to change the viewmodel property. I know there are several classes involved with the DataState stuff including: BindingListener.cs ConverterHelper.cs DataStateBehavior.cs DataStateSwitchBehavior.cs DataTrigger.cs Any clues would be good, Thanks

• Raphael JS - Parsing an SVG on the fly

  - by Chris

  I found a neat SVG parser at http://bkp.ee/atirip/ which parses an SVG file and outputs it into javascript that uses the Raphael JS library (raphaeljs.com). You'll notice in the source code at http://bkp.ee/atirip/svg2rdemo.php : <script> jQuery(document).ready( function() { $("#c1").each(function(){ var c = Raphael(this, 190, 154, 0, 0); var g1 = c.set(); ... it creates variables like g1, g2, etc. But it also reuses these variables. I would like to create unique variables for each group. In my .ai file, I have named my groups and I would like to use these names to create the variable names. Where in http://bkp.ee/atirip/f/svgToRaphaelParser.php.zip should I look to make this change?

• CNAME Record in .htaccess file: correct format?

  - by Josh

  In my .htaccess file, I have set up several A records in the following structure: RewriteCond %{HTTP_HOST} ^domain.com$ [OR] RewriteCond %{HTTP_HOST} ^www.domain.com$ RewriteRule ^substring\/substring\/etc?$ "http\:\/\/domain\.com\/newsubstring\/etc\/" [R=301,L] Is is possible to easily set up a CNAME record in the same fashion and put it in my .htaccess file? Unfortunately, my dumb DNS (namecheap) doesn't let me change CNAME records because my site actually has hosting and isn't just a parked domain. (I actually just want to set up a CNAME for www, since at the moment www.domain.com doesn't work for me, and only domain.com -- I'm going to point the former to the latter.)

• Putting data from local SQL database to remote SQL database without remote SQL access enabled (PHP)

  - by Shyam

  Hi, I have a local database, and all the tables are defined. Eventually I need to publish my data remotely, which I can do easily with PHPmyadmin. Problem however is that my remote host doesn't allow remote SQL connections at all, so writing a script that does a mysqldump and run it through a client (which would've been ideal) won't help me here. Since the schema won't change, but the data will, I need some kind of PHP client that works "reverse". My question is if such a client exists and what would be recommended to use (by experience). I just need an one way trip here, from my local database (Rails) to the remote database (supports PHP), preferable as simple and slick as possible. Thank you for your replies, comments and feedback!

• ExtJS RowEditor on Grid

  - by Ian Warner

  Hi When my users edits the Grid via RowEditor combo entries and checkboxes are annoying 1 Apple 2 Orange 3 Pear For instance with the combo above the user will select Orange then update - the Grid now instead of saying orange will display the number 2 - I would like it to show orange when a successful edit has been made. code for my combo editor : { allowBlank : false, displayField : 'team', editable : false, emptyText : 'Select Team', forceSelection : true, lazyRender : true, mode : 'remote', name : 'team', store : storeTeam, triggerAction : 'all', valueField : 'id', xtype : 'combo' } I think I read that you could send the complete row back to insert or I should listen to the update of the grid and then change the field but I need some guidance on what is best Cheers

• Visual Studio DataSet Designer Refresh Tables

  - by LnDCobra

  In visual studio datasource designer(The screen where you have all the UML Diagrams including relations) is there any way to refresh a table and its relations/foreign key constraints without refreshing the whole table? The way I am doing it at the moment is removing the table and adding it again. This adds all the relations and refreshes all fields. Also if I change a fields data type, is there a way to automatically refresh all the fields in the datasource? Again without deleting the table and adding it again. Reason for this is because some of my TableAdapters have quite a number of complex queries attached to them and when I remove the table the adapter gets removed as well including all its queries. I am using Visual Studio 2008 and connecting to a MySQL database.

• How to conditionally exclude features from "FeaturesDlg" in WiX 3.0 from a managed Custom Action (DT

  - by Gerald

  I am trying to put together an installer using WiX 3.0 and I'm unsure about one thing. I would like to use the FeaturesDlg dialog to allow the users to select features to install, but I need to be able to conditionally exclude some features from the list based on some input previously received, preferably from a managed Custom Action. I see that if I set the "Display" attribute of a Feature to "hidden" in the .wxs file that it does what I want, but I can't figure out a way to change that attribute at runtime. Any pointers would be great.

• iPad Web App: Detect Virtual Keyboard Using JavaScript in Safari?

  - by LKM

  I'm writing a web app for the iPad (not a regular App Store app - it's written using HTML, CSS and JavaScript). Since the keyboard fills up a huge part of the screen, it would make sense to change the app's layout to fit the remaining space when the keyboard is shown. However, I have found no way to detect when or whether the keyboard is shown. My first idea was to assume that the keyboard is visible when a text field has focus. However, when an external keyboard is attached to an iPad, the virtual keyboard does not show up when a text field receives focus. In my experiments, the keyboard also did not affect the height or scrollheight of any of the DOM elements, and I have found no proprietary events or properties which indicate whether the keyboard is visible.

• Java SWIFT Library

  - by jkl

  I'm looking for a Java library for SWIFT messages. I want to parse SWIFT messages into an object model validate SWIFT messages (including SWIFT network validation rules) build / change SWIFT messages by using an object model Theoretically, I need to support all SWIFT message types. But at the moment I need MT103+, MT199, MT502, MT509, MT515 and MT535. So far I've looked at two libraries AnaSys Message Objects (link text) Datamation SWIFT Message Suite (link text) Both libraries allow to accomplish the tasks mentioned above but in both cases I'm not really happy. AnaSys uses a internal XML representation for all SWIFT messages which you need to know in order to access the fields of a message. And you need to operate on the DOM of the XML representation, there is no way to say "get the contents of field '50K' of the SWIFT message". And the Datamation library seems to have the nicer API but does not find all errors. So does anyone know other SWIFT libraries to use?

• VBA ActiveX controls grow in size over Remote Desktop Connection

  - by Alistair Knock

  We have an Excel workbook with a number of ActiveX controls, running in Excel 2003 on Windows XP. When connecting using Remote Desktop, the ActiveX controls change font, sometimes font size, and sometimes orientation (in the case of a spinner control). This happens on first connection and also as the workbook is used - some of the controls then enlarge in size, often overlapping other controls and part of the workbook. I read somewhere this may be caused by improper connection management (not closing them) leading to increasing memory usage; are there other reasons why the display is so different over Remote Desktop and are there workarounds? (the properties of each control usually remain the same, so force-resizing them doesn't always have an effect)

  Hi, on ScottGu's Blog is an Example how to use MVC2 Custom Validation with EF4: http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx So here the Problem: When the Designer in VS2010 creates the Objects for the DB, along to the example you have to add [MetadataType(typeof(Person_validation))] Annotation to that class. But when i change anything in the Designer all these Annotations are lost. Is it possible to keep self made changes to the edmx file, or is there any better way of applying System.ComponentModel.DataAnnotations to the generated Entities? Thanks.
