• PostgreSQL / Ruby for commercial application

  - by RPK

  I am planning a web-based commercial application with front-end RoR and back-end PostgreSQL. I've some confusion about RoR and PostgreSQL Edition to use. For RoR, I have Aptana RADRails installed. For PostgreSQL, a free variant is also available at EnterpriseDB. Previously I installed a free EnterpriseDB PostgreSQL variant and it was very smooth and had professional touch. It was quite different from the one available from PostgreSQL website. I want to know which IDE and RoR variant to use for my project. I have no idea of Ruby and Rails. I will be learning and developing simultaneously. Also, which PostgreSQL variant to use? Can these two technologies be used for a developing a commercial application?

• How to use SAPI's SetNotifyCallbackFunction() in a CLR project with Windows Form as the interface wi

  - by manuel

  Hi, I'm trying to write a dll plugin for Winamp. I'm using Microsoft Visual Studio 2008 and Microsoft SAPI 5.1. I created the interface window using Windows Form (System::Windows::Forms::Form). I tried to use SetNotifyWIndowMessage(), but the method is never called when I speak to the microphone. So I tried using SetNotifyCallbackFunction(), but I got a compile error saying that I should use '&' in front of the method name in the parameter. However, when I add the '&', I got another compile error saying that i can't take the address of the method unless creating delegate instance. What should I do? Someone please help me..

• C# Social Networking SDK

  - by Nix

  I am currently gathering some technology requirements for a site that will be a social network based. I don't want to re-invent the wheel so i am looking for some type of SDK or collection of tools that can provide me with a way of creating/managing a social network. I understand that no framework will probably fit my exact needs so I am also looking for a flexible/extendable framework. An example extension point would be allowing the user to provide sub networks, maybe a global network that could be sub classified as work and friends. Beyond that it would also be nice to somehow be able to import contacts from other networking sites (Facebook, Linked In, etc). My current technology suite will consist of the following: IIS 7.0 WCF Data Services SQL Server 2006 ASP.NET front end. If there is any more information you may need please let me know.

• CodeIgniter & Datamapper as frontend, Django Admin as backend, database tables inconsistent

  - by Rasiel

  I created a database for a site i'm doing using Django as the admin backend. However because the server where the site is hosted on, won't be able to support Python, I find myself needing to do the front end in PHP and as such i've decided to use CodeIgniter along with Datamapper to map the models/relationship. However DataMapper requires the tables to be in a specific format for it to work, and Django maps its tables differently, using the App name as the prefix in the table. I've tried using the prefix & join_prefix vars in datamapper but still doesn't map them correctly. Has anyone used a combination of this? and if so how have the fixed the issue of db table names being inconsistent? Is there anything out there that i can use to make them work together?

• Sharepoint SSO bulk creation of user accounts

  - by user292884

  Hopefully someone can help... I need to provide client with a solution to allow bulk creation of user accounts into SharePoint SSO. The client wants to provide an excel spreadsheet with accounts, usernames and passwords and have that created in the SSO database. I've been told its possible but I can't see how and google is failing me. I've been told its "some custom development and the SharePoint object model". As far as I can see all of the credentials stuff in the Microsoft.SharePoint.Portal.SingleSignon namespace is very much read only. I have a solution which is to get them to save the spreadsheet as a CSV file and to use jmeter to squirt the data in through the front end. I don't think that's really an acceptable solution though. Anyone got any clues? Or can anyone say definitively this can't be done? Thanks in advance...

• RadWindow AlwaysOnTop

  - by klausbyskov

  Does anyone have any experience with the RadWindow wpf control from Telerik? My problem is that when I open a RadWindow and minimize my application then when I maximize the application the RadWindow is not visible. I can use alt+tab to get the RadWindow in front again, but I would really like to avoid having to do this. I'm doing the following to display the RadWindow: this.theWindow.ShowDialog(); Where theWindow is an instance of a class that inherits from RadWindow. Any ideas?

• How to represent "options" for my plugin architecture (C# .NET WinForms)

  - by Joshua

  Okay basically here's where I'm at. I have a list of PropertyDescriptor objects. These describe the custom "Options" fields on my Plugins, aka: public class MyPlugin : PluginAbstract, IPlugin { [PluginOption("This controls the color of blah blah blah")] [DefaultValue(Color.Red)] public Color TheColor { get; set; } [PluginOption("The number of blah blah blahs")] [DefaultValue(10)] public int BlahBlahBlahs { get; set; } } So I did all the hard parts: I have all the descriptions, default values, names and types of these custom "plugin options". MY QUESTION IS: When a user loads a plugin, how should I represent these options for them to config? On the back end I'll be using XML for the config, so that's not what I'm asking. I'm asking on the front end: What kind of WinForms control should I use to let users configure the options of a plugin, when there will be an unknown amount of options and different types used etc.?

• Java OpenGL color material darkens when depth test is disabled

  - by Jeff Storey

  I've been working with the depth buffer in OpenGL (JOGL) to ensure certain items are rendered in front of others by disabling the depth buffer (detailed in my previous question http://stackoverflow.com/questions/2516086/java-opengl-saving-depth-buffer). This works, except when I set the color of an item that is being drawn when the depth test is disabled, none of the material shininess shows up. The item is rendered as a darker version of the original color (it seems like there is no lighting effect really applied to it). Is there a reason why this would be happening? and how might I prevent this? thanks, Jeff

• Queueing Effect.Parallels in Scriptaculous doesn't work

  - by Matthew Robertson

  Each block of animations, grouped in an Effect.Parallel, runs simultaneously. That works fine. Then, I want each of the Effect.Parallels to trigger sequentially, with a delay. The second block doesn't wait its turn. It fires when the function is run. Why?! ///// FIRST BLOCK ///// new Effect.Parallel([ new Effect.Morph... ], { queue: 'front' }); ///// SECOND BLOCK ///// new Effect.Parallel([ Element.toggleClassName($$('#add_comment_button .glyph').first(), 'yay') ], { sync: true, queue: 'end', delay: 1 }); ///// THIRD BLOCK ///// new Effect.Parallel([ new Effect.SlideUp... ], { queue: 'end', delay: 4 });

• SSL cert install in Mongrel

  - by normalocity

  Running a RoR app. I've created a self-signed SSL cert for my test/dev environment, which consists of a single mongrel, and Mac OS X Leopard. Can I install the SSL cert in such a way that mongrel will use it, or do I have build a different server stack to handle SSL (e.g. Apache in front of a mongrel cluster), and install the cert inside of Apache? For my production server, I'll eventually build a server stack like this, so it's no big deal if I have to go that direction - it's just a question of now or later. Thanks!

• Win32 API Question

  - by Lalit_M

  We have developed a ASP.NET web application and has implemented a custom authentication solution using active directory as the credentials store. Our front end application uses a normal login form to capture the user name and password and leverages the Win32 LogonUser method to authenticate the user’s credentials. When we are calling the LogonUser method, we are using the LOGON32_LOGON_NETWORK as the logon type. The issue we have found is that user profile folders are being created under the C:\Users folder of the web server. The folder seems to be created when a new user who has never logged on before is logging in for the first time. As the number of new users logging into the application grows, disk space is shrinking due to the large number of new user folders getting created. Has anyone seen this behavior with the Win32 LogonUser method? Does anyone know how to disable this behavior?

• Can I disable DataAnnotations validation on DefaultModelBinder?

  - by Max Toro

  I want DefaultModelBinder not to perform any validation based on DataAnnotations metadata. I'm already using DataAnnotations with DynamicData for the admin area of my site, and I need a different set of validation rules for the MVC based front-end. I'm decorating my classes with the MetadataType attribute. If I could have different MetadataType classes for the same model but used on different scenarios that would be great. If not I'm fine with just disabling the validation on the DefaultModelBinder, either by setting some property or by creating a specialized version of it.

• Need to execute an ajax call incrementally after fixed time periods in javascript?

  - by Ali

  HI guys, I need to be able to make an ajax call to be made after every few minutes. Basically the ajax call would be to check on new emails in an inbox. If there are new emails it would download the emails to a database. I got all the server side code set up fine. I just need to know how do I set up on the front end the part where the ajax call is made after every few minutes plus it should be set up such that we don't end up with parallel ajax calls being made i.e if the ajax call hasn't returned a response it shouldn't start a new ajax request.

• Silverlight 4 - authentiation / authorization against custom wcf service

  - by Calanus

  I have a wcf service in front of an AzMan store that passes roles and operations to clients using the following interface: [OperationContract] bool AuthenticateUser(string password, string appName); [OperationContract] string[] GetRoles(string storelocation, string appName); [OperationContract] string[] GetOperations(string storeLocation, string appName, string selectedRole); Clients connect to this service using windows authentication (but users must send their password through to reaffirm their identity). Ultimately the service delivers an array of operations that each client can perform based on their selected role. I've opened a new Silverlight Business Application and tried to understand how authentication/authorization works in this template, as well as scoured the web to find examples to how to hook my webservice to the login box already created in the template, but I am completely at a loss as how to do this! Can anyone offer any advice?

• Recommended resources for learning MS Expression Blend

  - by fastmonkeywheels

  I've been designing applications using C# for some time now but I have the need to create a more custom application and Expression Blend was recommended to me. I've downloaded the free trial but it's a little fancier than I expected. I'm not a graphic designer and can't use photoshop to save my life, however I do have images provided by a graphic designer to use for this application. I'm looking for some good resources for learning Blend and using it as a front end to a C# application, much like I would a regular C# forum.

• Inform Activity from a BroadcastReceiver ONLY if it is in the foreground

  - by Zordid

  Hi there! Maybe it's easy, but I couldn't really figure this out right so far... I got a BroadcastReceiver waiting to get triggered by the AlarmMangager - this works fine. Now: because the event, if it occurs, needs to refresh some elements on screen of the main Activity, I would like to send an Intent from that background BroadcastReceiver to my Activity - but only if it is currently in the foreground, aka active. If it is not running or not visible, I don't care - and the last thing I want to do is start the Activity by my intent! I handle repainting of the views in my onResume method, so I don't care at all. Any hints on how to do that? Thanks! EDIT: my BroadcastReceiver is waiting for alarms that must be notified to the user. So, it must be there and declared in the manifest. The problem is: it will have to decide whether the mentioned Activity is currently up in front or not.

• Properly using subprocess.PIPE in python?

  - by Gordon Fontenot

  I'm trying to use subprocess.Popen to construct a sequence to grab the duration of a video file. I've been searching for 3 days, and can't find any reason online as to why this code isn't working, but it keeps giving me a blank result: import sys import os import subprocess def main(): the_file = "/Volumes/Footage/Acura/MDX/2001/Crash Test/01 Acura MDX Front Crash.mov" ffmpeg = subprocess.Popen(['/opt/local/bin/ffmpeg', '-i', the_file], stdout = subprocess.PIPE, ) grep = subprocess.Popen(['grep', 'Duration'], stdin = subprocess.PIPE, stdout = subprocess.PIPE, ) cut = subprocess.Popen(['cut', '-d', ' ', '-f', '4'], stdin = subprocess.PIPE, stdout = subprocess.PIPE, ) sed = subprocess.Popen(['sed', 's/,//'], stdin = subprocess.PIPE, stdout = subprocess.PIPE, ) duration = sed.communicate() print duration if __name__ == '__main__': main()

• Using COM to open Word

  - by chupinette

  Hello! I am actually trying some codes i found from http://php.net/manual/en/class.com.php <?php // starting word $word = new COM("word.application") or die("Unable to instantiate Word"); echo "Loaded Word, version {$word->Version}\n"; //bring it to front $word->Visible = 1; //open an empty document $word->Documents->Add(); //do some weird stuff $word->Selection->TypeText("This is a test..."); $word->Documents[1]->SaveAs("Useless test.doc"); //closing word $word->Quit(); //free the object $word = null; ?> But this does not seem to work. I am using Word 2007 and i get the following: Loaded Word, version 12.0 Fatal error: Call to undefined method variant::SaveAs() in C:\xampp\htdocs\final\testq.php on line 14 Can anyone solve this problem? Is it because i am using Word 2007?

• How do I get the intellisense in FoxPro 8 to work with .net COM objects?

  - by IsaacB

  Hi, I'm at my wit's end with this. What I'm doing is making a C# dll file that needs to have some methods exposed to FoxPro 8. This guy here http://www.west-wind.com/presentations/VfpDotNetInterop/DotNetFromVFP.asp says that you can put [ClassInterface(ClassInterfaceType.AutoDual)] in front of the (C# in my case) class, and then intellisense in Foxpro magically works. I'm accessing the COM object fine in FoxPro, but unfortunately the intellisense doesn't work, and it's annoying me. Is there some other step I'm missing to this? Is there some registry entry to look for to confirm that the methods are exposed properly (for intellisense to work)? Are there other steps in Foxpro that I'm supposed to follow (I don't know a thing about FoxPro!) It might be a pretty obscure question these days, but someone on here must know the answer! Thanks

• Hooking up Sproutcore frontend and custom Python backend

For the backend, we have our own python API which handles all transactions with multiple databases. What is the best way to hook up the front-end with the back-end. AFAIK django is pretty monolithic (correct me if i am wrong) and it would be cumbersome if I dont use its native ORM...I would prefer a python-based solution..any ideas? thanks! Suvir

• Programmatically modifying an embedded resource before registering/referencing it on the page

  - by Jimock

  Hi All, Firstly, "Modifying" may be the wrong term, I see a few people have posted online just asking whether they can actually modify an embedded resource. What I am wanting to to, is use a resource in my assembly as a kind of template which I would do a find and replace on before registering it on the page - is this possible? For example; say I have a few lines of jQuery as an embedded resource in my assembly and in this script I am referencing a CSS class name that can be set by the front-end programmer. Since I do not know what the CSS class will be until implementation, is there a way of going through the embedded resource and replacing, say, $myclass$ with ThisClassName. Any help would be appreciated, if it's not possible then at least tell me so I can stop chasing my tail. Cheers, James

• iPhone - Dismiss modal view by a UITabBarController

  - by ncohen

  Hi everyone, I've got into a very strange problem. I created my own UITabBarController to customize it and it works pretty well... except for the modal views. When I dismiss the modal view (present/dismiss from the UITabBarController) with an animation, it waits until the animation did finished and goes to the first controller of the tab bar! Why does the controller change? and how can I fix it? Thanks PS: My UITabBarController view is on the main window and has a UITabBar on it. The controllers (which are managed by the tab bar) are on the main window over the tab bar controller view with a shorter height. When I present the modal view, I bring the tab bar controller view to front.

• Grails URL's with Tomcat/Apache ProxyPass

  - by intargc

  Grails tends to write out the URL for everything that uses its tags as /appName/whatever. For instance, if I use the tag: <g:javascript library="jquery"/> the resulting tag is <script src="/appName/jquery/jquery.js"></script> This causes an issue with using ProxyPass with Apache/Tomcat. All of my CSS, JS, Images and links have that /appName prefixed to them. Is there a way to work around this with ProxyPass or possibly a way for Grails to not prefix the appName to the front of all of my URL's?

• Different sidebars for each Wordpress page

  - by Remy

  I'm making a Wordpress 2.9.2 theme, and I'd like each page to have its own sidebar than can be edited as easily as the page's content. It would be cumbersome to make a different template file for each sidebar. It would also be weird to add a "custom field" containing all the sidebar text, since I wouldn't be able to use the Visual/HTML editor. What I'd like is to have a tag similar to the tag, but instead of delimiting the content to be shown on the front page, it would split the post's content and sidebar. Is this possible? Or is there a better solution?
