• Entitiy Framework: "Update Database from Model" instead of "Generate Database from Model"

  - by David

  Hey everyone, I have created a Entity Framework 4 model with Visual Studio 2010 and generated a database from it. Now I found myself adding new properties (with default values), changing documentation of columns, changing names of columns, changing types of columns several times. All tasks that do not require much "extra work" in order not to be possible to be achieved automatically (in my humble opinion). Everytime I did "Generate Database from Model" and lost of course the table data. Is there a way just to update the database's architecture so to say - leaving the table data untouched? Maybe with some user interaction especially when changing types etc.? Or would this functionality be simply too difficult to be realized to work in a reliable way? Thanks in advance! Cheers, David

• Is this a cache problem? (JQUERY)

  - by Scarface

  Hey guys quick question. I have this code that brings in data from a php script and it works fine some of the time. However, once in a while the information will not appear at all in opera if I keep refreshing. About Is every 3 refreshes. It seems to be fine in firefox. Is this a cache problem and can it be fixed? Thanks in advance for any assistance. $.getJSON(files+"comments.php?action=view&load=initial&topic_id="+topic_id+"&t=" + (new Date()), function(json) { if(json.length) { for(i=0; i < json.length; i++) { $('#comment-list').prepend(prepare(json[i])); $('#list-' + count).fadeIn(1500); } } });

• How to override a render to create a custom "render :my_format => argument" in rails 2.3(.5)?

  - by Rafael

  Hey! I would like to create a custom render as specified in title. For instance, I have my controller: class MyController < ApplicationController def index respond_to do |format| format.html # index.html.erb format.xml { render :xml => @objs } end end end , but I would like something like this: class MyController < ApplicationController def index respond_to do |format| format.html # index.html.erb format.xml { render :xml => @objs } format.my_format { render :my_format => @objs } end end end Is it possible? What are the steps I need to make it work? Thanks in advance! UPDATE I want something like in here. So I replaced the @objs with a method but it didn't work either (the method wasn't called). Obs: I register the mime type at config/initializers/mime_types.rb.

• Eclipse IDE's Hello World Cheatsheet seems to have a mistake

  - by Sean

  Hey guys, Just a warning: I'm completely new to Java and am trying to teach myself Android programming. I installed the Eclipse IDE today and tried to walk through the first Java Hello World "cheat sheet," and it didn't work! I was really quite surprised. When it asked me to select the checkbox to create the main() method, there wasn't anything on-screen that looked like a checkbox with "main()" or "method" next to it, so I guessed that maybe what they meant was the "Modifiers" radio button. So I left that checked for "public." It didn't compile and I got red X's next to every folder in my Package Explorer. Has anybody else had this problem? Thanks!

• Stop SWF file from repeating

  - by Samuel

  Hey people, I have converted a short clip to an .swf file, i want to implement it on my website: <object width="400" height="300"> <param name="movie" value="movie.swf"> <embed src="movie.swf" width="400" height="300"> </embed> </object> When i play it it autoplays (that's fine) but it also keeps repeating over and over, i'd like it to stop at the end and just display the end frame (as mentioned i converted a movie so i cant do it with actionscript in the .fla file). Thanks for any tips!

• Changing a form's action attribute in IE?

  - by Jonatan Littke

  Hey. I'm trying to set a hash value in a form's action, to keep it when the form is submitted. Firefox allows me to update the hash and redirects accordingly, but IE doesn't. I initially thought this was related to IE not allowing hash values in the action attribute at all, but it seems I can't dynamically set the action at all in IE - with a hash or not? Is that right? I'm using the following jQuery: $("#options-form").attr('action', '#' + hash); To update: <form id="options-form" action="" method="get"> (On a sidenote, this wasn't needed in Firefox, because FF appears to preserve the current hash if it was only the GET params that changed.)

• Good tools which generate NUnit unit tests for .NET assemblies in Visual Studio 2008

  - by andy

  Hey guys, I'm pretty new to Unit Testing so bare with me. I realize that best best practice is not to auto generate unit tests, however I'd like to use Code Generation to set-up the basic skeleton of the tests. Now, I know Visual Studio 2008 already has the built in "create tests", however, it just creates a flat list of all the classes it's going to test... and it's not for NUnit right? Ideally, I'd like the code generation to follow the folder AND namespace structure of the assembly its generating tests for. Can you guys recommend any good tools which generate NUnit unit tests for .NET assemblies in Visual Studio 2008? cheers!

• difference between adobe flash media server products

  - by Oren Mazor

  Hey folks, I've been told that I can only record streams with flash media interactive server. I already have Flash media streaming server running to stream flvs. it would seem to be trivial to set up the interactive server, and adobe obliges me by having a developer download. however, once I extracted that download, it appears to contain just standard flash media streaming server? is adobe screwing with me? the more I look into this the more it seems that nobody is actually differentiating between the two except adobe (who charge $1000 for fms, and $4000 for fmis).

• Send and recieve multiple ssh commands via java runtime and cygwin

  - by Moustachio

  Hey I have run into the following problem when attempting to build a program in java which executes commands on a remote linux server and returns the output for processing... Basically I have installed Cygwin with an SSH client and want to do the following: Open Cygwin, Send command "user@ip"; Return output; Send command "password"; Return output; Send multiple other commands, Return output; ...etc... So far: Process proc = Runtime.getRuntime().exec("C:/Power Apps/Cygwin/Cygwin.bat"); Works nicely except I am at a loss as to how to attempt the next steps. Any help?

• QFileDialog and german umlaute within a path

  - by MB

  Hey Everybody, i am working on a project, which i am developing with Python and PyQT4. I have stumbled upon a somewhat odd behaviour of the QFileDialog, that is not occuring when running the project within in my IDE (Eclipse). The problem is that QFileDialog in ExistingFiles-mode does fail to return the list of selected files, when one of the file paths is containing a german umlaut (ä,ü,ö, etc.) The QFileDialog is not offering options or parameters to make it sensible regarding this scenario. Does anyone have any ideas of how to tackle this issue?

• Scipy sparse... arrays?

  - by spitzanator

  Hey, folks. So, I'm doing some Kmeans classification using numpy arrays that are quite sparse-- lots and lots of zeroes. I figured that I'd use scipy's 'sparse' package to reduce the storage overhead, but I'm a little confused about how to create arrays, not matrices. I've gone through this tutorial on how to create sparse matrices: http://www.scipy.org/SciPy_Tutorial#head-c60163f2fd2bab79edd94be43682414f18b90df7 To mimic an array, I just create a 1xN matrix, but as you may guess, Asp.dot(Bsp) doesn't quite work because you can't multiply two 1xN matrices. I'd have to transpose each array to Nx1, and that's pretty lame, since I'd be doing it for every dot-product calculation. Next up, I tried to create an NxN matrix where column 1 == row 1 (such that you can multiply two matrices and just take the top-left corner as the dot product), but that turned out to be really inefficient. I'd love to use scipy's sparse package as a magic replacement for numpy's array(), but as yet, I'm not really sure what to do. Any advice? Thank you very much!

• HOM with Objective C

  - by Coxer

  Hey, i am new to objective C, but i tried to use HOM in order to iterate over an NSArray and append a string to each element. here is my code: void print( NSArray *array ) { NSEnumerator *enumerator = [array objectEnumerator]; id obj; while ( nil!=(obj = [enumerator nextObject]) ) { printf( "%s\n", [[obj description] cString] ); } } int main( int argc, const char *argv[] ) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSArray *names = [[NSArray alloc] init]; NSArray *names_concat = [[NSArray alloc] init]; names = [NSArray arrayWithObjects:@"John",@"Mary",@"Bob",nil]; names_concat = [[names collect] stringByAppendingString: @" Doe"]; print(names_concat); [pool release]; } What is wrong with this code? My compiler (gcc) says NSArray may not respond to "-collect"

• sys.stdout not reassigning to sys.__stdout__

  - by Vince

  I'm pretty new to Python so I am still just learning the language. One of the things I came across was reassigning sys.stdout to change the default output of print. So I wrote this as a test: import sys sys.stdout = open('log.txt','a') print('hey') sys.stdout.close() sys.stdout = sys.__stdout__ print('hi') Now the string 'hi' is not written to the file but it does not show in the default output either. When I assign some other variable to sys.stdout in the beginning and change it back it works, but I'm just wondering why its not changing back the first time.

• Runtime Error 424 Object Required

  - by Luis

  Hey so I get this error in this code: Private Sub Request_Stuff_button_Click() Call Main.createObjects Call My_Control.requestStuff End Sub at the 'Call My_Control.requestStuff' line. The 'Main' module looks like this: Public My_Control As ControlObject Public Sub createObjects() If My_Control Is Nothing Then Set My_Control = New ControlObject End If End Sub The weirdest thing is that when I add Dim x As Integer x = My_Control.dummyInt right before the line that gets me the error, x gets the correct value right before the error happens which means My_Control is definitely an object and is definitely not nothing. This error is killing me, thanks in advance.

• Gothic Medieval font that you can embed With Cufón?

  - by BioGeek

  Hey, I'm looking for a font in Gothic Medieval style that I can embed with Cufón. I tried with the Cloister Black .ttf file but the generator responded with: The file you uploaded could not be converted. Currently only TrueType (TTF), OpenType (OTF), Printer Font Binary (PFB) and PostScript fonts are supported. If you're sure the font is valid, it is likely that the author of the font has decided to not allow modification and/or embedding of the font. This can happen quite often especially with "freeware" TrueType fonts. You must contact the author of the font for a less restricted version.

• Microsecond (or one ms) time resolution on an embedded device (Linux Kernel)

  - by ChrisDiRulli

  Hey guys, I have a kernel module I've built that requires at least 1 ms time resolution. I currently use do_gettimeofday() but I'm concerned that this won't work once I move my module to an embedded device. The device has a 180 Mz processor (MIPS) and the default HZ value in the kernel is 100. Thus using jiffies will only give me at best 10 ms resolution. That won't cut it. What I'd like to know is if do_gettimeofday() is based on the timer interrupt (HZ). Can it be guaranteed to provide at least 1 ms of resolution? Thanks!

• Using Facebook Graph to simply post a wall message with just javascript

  - by Glycerine

  Hey guys, Now I know this question has been asked similarly a lot of times but I'm really struggling here. Its a simple thing I need to do: I would like to post a message onto a users wall saying "I scored 8/10 on objects game" then a URL Thats it. I don't mind if facebook needs to authenticate and then post the message. and I really don't want to have to use the full API - as I don't want to handle user login details. Is it possible using the new Graph API and javascript. Uber thanks guys this'll allow me to sleep tonight.

• Changing error message for datatype validation?

  - by Matthias

  Hey guys, I've a small question on ASP.NET MVC 2. I'm using Data Annotations on my Presentation Model and its model binder per default. But one step back, I want to do the most elementary thing: validation of the data type. Let's say I have an "int ID" on my model and want to edit the according entity in my view. If I enter something wrong like "foo", then I get a model error back, but the validation message is on English. I want to have this message in other languages, too. How can I do this? I remember that in MVC 1 I've written a custom model binder which checks the data types, but that's not what I want to do (at least not in MVC 2). Thus I hope there is a better way... Thanks, Matthias

• ruby on rails, searchlogic and refactoring

  - by JohnMerlino

  Hey all, I'mt not too familiar with searchlogic plugin for rails (I did view the railscasts but wasn't helpful in relation to the specific code below). Can anyone briefly describe how it is being used in the three methods below? Thanks for any response. def extract_order @order_by = if params[:order].present? field = params[:order].gsub(".", "_") field = field.starts_with?('-') ?

• WCSF vs MEF, What's Best For Me?

  - by Galilyou

  Hey fellows, I'm working on a large web application that includes many modules (CRM, Inventory, Administration, etc.) What I want to accomplish is to be able develop each of these modules independently (the UI, Core Logic, DataAccess Logic, and all) and then integrate them all together into a core module (this integration should only be a change in the configuration file). For example, if I have a core module named Host, I should be able to add the CRM module to the host module by simply adding this line to the host's configuration file: <module name="CRM" /> I did some reading on the WCSF, and found that it can help integrate some modules together, but it really doesn't offer so much help in terms of integrating those UI elements. Some friends suggested MEF for the job, but I haven't looked at that yet. What do you guys think? Is it possible to achieve this level of modularity, and how much work do I have to put into it to get it working?

• WPF storyboard object access.

  Hey, I'm new to silverlight and wpf programming I've just created a simple storyboard in silverlight which increases height and width of a button. As I wanted, I wrote this code so that whenever I move cursor on the button storyboard begins. here is the code used for silverlight. private void button_MouseEnter(object sender, System.Windows.Input.MouseEventArgs e) { if(Storyboard1.GetCurrentState()!=ClockState.Active) Storyboard1.Begin(); } Everything is fine in above scenario as far as I use silverlight. But now I wanted to use the same functionality in WPF. But the problem I faced is that in WPF button click event handler I can't access the Storyboard1 object. Please help me to access the storyboard object in event handler.
