• Base-camp Style Subdomains and IDs of Models

  - by Newy

  I have an app that has Basecamp-style subdomains, that is, I have Projects, Users, Apples and Oranges. The Users, Apples and Oranges are all keyed to a Project and only exist in the http://project.myapp.com. I added a project_id to Users, Apples and Oranges and everything works, except of course that the ids of those three objects increment globally, and throughout my app I lookup objects by that id. This doesn't seem like best practice. Should I instead do lookups by a secondary key? How does that affect efficiency? If there's a good blog post that covers this, would be wesome.

• Is it possible to add a New Project Wizard with a VSPackage?

  - by Gerald

  I have a VSPackage for Visual Studio 2008 that I created for adding some editor and custom language functionality. I also have a need to add a new project/solution wizard to create a new Solution and a complex series of C++ projects to the solution. I know I can do this using a "Custom Wizard", but I would be much happier if I can implement this within my VSPackage using C# instead. So I guess the main question is, is it possible to add an entry to the Project Types dialogs in Visual Studio from a VSPackage? Or is the "Custom Wizard" and JScript my only option here? And if it's possible, where can I find information and/or samples on how to accomplish this?

• Google maps nearest points avoiding rivers / by itinerary

  - by Karl Lacroix

  Here is the deal : I need to find the closest points from a point with a radius. For example, I need to get all the points in a 15 km radius. Thats easy with Google Maps Radius and all the examples on the web ;) The problem is that from my office, a point is under the 15km radius, but it's on the other side of a river, so the car itinerary is about 30 km (using a bridge)! Is there a simple solution to exclude those points or to calculate by intineraries ? I supposed that I'll need to calculate all itineraries with returned points? DirectionsRequest API? Thanks! :)

• tips for learning from opensource

  - by dole doug

  Hi there, Besides practice(practice and more practice) reading books and forums, analyzing others people code is a must in order to have a career in this field. The problem is that I'm a student(feels like always on learning stage) but sometimes i can't solve the problems by my own. I was thinking that on public open source repositories might be the answer I'm looking for. My question is how can i find the answer to some of my problems in open source projects/community? Do you have any tips to share for me? ty

• website creation - for non web programmers?

  - by Tim

  I thought I would find decent questions and answers for this, but none really caught my eye... I am a C++ developer and I own a few domains. I'd like to start off with simple web sites for each with a minimum of time and fuss and minimum learning. I have too many projects going and don't have the time to learn how to build websites. One is for a company that currently has only a single product with custom development as well. I hacked together some really bad html with paypal links on it. It is just one simple product. I want to add uservoice to it and maybe some other stuff like FAQ, forums, etc. Right now I just link to a google group I created. Another is a startup in development phase, but we want to provide simple content like whitepapers and press releases and a section for investors. - mostly an "about us" type of thing. We will also be providing details about our product. Then there is a blog site - currently using godaddy's quickblogcast. Not a bad start but I suspect I want to move to something else. The question is - is there a framework that I can use that will make decent, if not outstanding, sites? Again, I have my hands full with three projects in addition to my day job and don't have time to learn web programming. I also don;t want to just pay a web person and then be out in the cold for upgrades, changes, etc. I have been burned before. I am happy with a web-based app or a desktop app that builds html or whatever and then I can ftp it up to the hosting servers. To summarize: - simple to get started - low time to get a web page going - ability to integrate with a few hand-done pages - pay pal integration - uservoice integration - ability to put under my svn would be nice too EDIT Thanks to the responders. I understand now why my original searches failed. I was not searching for "CMS". I'll go back and do that. I would expect that this is a many-times-duplicate... EDIT: I am considering using Wordpress and Drupal - one for each of the sites. I did one Drupal site quickly just so I could qualify for one of the Microsoft programs for discounted dev tools - anyway - it was a quick and dirty homepage and I am still on the learning curve. I look forward to playing with it. So far it has been ok. I am not sure about doing a taste-test between the two - might be a waste of time where I could just become that much better at Drupal faster than spending time on wordpress... Will keep updated. EDIT: Selecting the Drupal answer by slim for now. That is what I am going with. Don't have time to check them all out. Wordpress sounds like a good option too, but such limited time... Results: I have tried wordpress and drupal so far. Wordpress is great for blogging or for a site that you want to run ads from, but I disagree that it is ready for a corporate site, unless you want to spend lots of time making your own theme, etc. But if you spend that time, why not work with drupal? Drupal was a little intimidating at first - but after spending about 4 hours reading the overview and step-by-step guide online was a HUGE step. I got a simple site up and running easily after that. Trying to make a website just by going to the admin panel without reading anything is a waste of time. You really need to read the docs. The site is great. start here: http://drupal.org/getting-started I'd suggest drupal to anyone. It has amazing capabilities, lots of support and lots of users. Just doing blogging? Wordpress is really great for that. So now I've got two sites running with a lot of the functionality I wanted - and they look good. ONE MORE EDIT Well, I have switched back to wordpress after buying a theme and then getting help from web developers. I guess either one will work - it is just a matter of getting comfortable witht he basics, using the right tools and trying things out.

• Animating resizing and moving UIView at the same time

  - by chouchou

  I'd like to "Stretch" a UIView to the right side, meaning increase it's frame.size.width by foo pixels and at the same time decreasing it's frame.origin.x by foo pixels, using [UIView beginAnimations] syntax. However, if I do that, when the animation begins the view immediately resizes, and then starts the animation for the origin. CGRect currFrame = someView.frame; currFrame.size.width += 100; currFrame.origin.x -= 100; [UIView beginAnimations:@"Anim1" context:nil]; someView.frame = currFrame; [UIView setAnimationDuration:0.7]; [UIView commitAnimations]; I've also tried breaking the animation down to 2 parts but then I can't keep the right position in place. Any help is much appreciated!

• How to convert a plist file from mac os project to iphone project?

  - by Tom Pace

  I am developing an app for the iPhone OS devices, and am using a third-party engine which is not well documented but I've made great progress with it anyway. The problem: The engine's developer strongly urges extending from the existing template projects bundled with the engine, but the engine's plist files are Mac OSX project plist files. This is an iPhone engine, and so I cannot understand why the plist file is structured to take keys for Mac OS apps, but that's how it is. I did a FileMerge comparison to ensure there was nothing within the file itself that defined its use for one OS or the other, so I guess it's defined somewhere in the project settings.

• Xcode 4.2 how include one project into another one?

  - by Alex Stone

  I keep searching, but cannot find a clear and simple explanation on how to include one XCode project, along with all of it's sub-classes into another project. I routinely see stuff like that in sample projects that I download off the web, but do not know how to do this myself. Within XCode, along with .h and .m files, and folders, there's a whole new project, starting with a blue xcode project icon, that is expandable to contain everything within the project. Please, can someone explain to me step by step what do I need to do to add one XCode project into another one? I've seen a ton of one liners like "header search paths", but that does not tell me much. UPDATE: After re-reading the documentation, I realized that the project to include must be dragged ONTO the BLUE project icon of the parent project. Regular sources can be dragged anywhere, but a project must be dragged onto a project. Thank you!

• Which is the best PDF library for PHP?

  - by Darryl Hein

  I'm wondering which is the best PDF creation library for PHP, mainly for creating PDFs from scratch (not as much HTML to PDF)? I have worked with FPDF for quite a while now, but it's getting quite old and hasn't had much for updates. I found TCPDF the other day (thanks you another question on SO). It seems very good and is based on FPDF so I don't think it'd be a big transition. FPDI also supports TCPDF which is nice as I have used it before and found it be useful. I have also seen DOMPDF but it too hasn't had many updates for quite some time and is lacking a lot of functionality for general PDF generation. Zend (Zend_Pdf) as well as many other libraries have their own PDF libraries or extend another one, but you often have to setup the entire library, which for existing projects can be a problem. What other libraries are there and what have your experiences with them been with the above or other libraries?

• HTTP redirect fallback

  - by Ondrej Stastny

  Hi, Is there a way to provide fallback URL when HTTP redirect times out? What I'm trying to achieve is that when I hit the original url, I would respond with HTTP redirect (300, 307?) giving the browser new URL and the fallback URL in case the new URL times out? I was also considering doing this client side but it just does not seem to be very effective (in terms of speed, client support). What I would do is probably have a tiny 1x1px image on each server, try loading it and then check with javascript which server is up and redirect there. Any other ideas? Thanks

• software that meets all needs in a project

  - by taz

  Hello all, I have a got couple of software projects that I want to run with my friends(max 10 persons) privately(at least for now). But I'm kind of lost between software management systems. I am not even sure about the definitions of my needs. Dear all, what is the definition/name of the system/software that meets my needs listed below? Continuous Integration? And please suggest me a good ALL-IN-ONE instance of it: project roadmap/planning project resource(people) allocation project issue&bug tracking project mailing list project forum project wiki source control server source control client repository change notifier client build system(like scons) nightly build automation IDE integration(VS) Note: I tried Redmine and liked it, but found it kind of slow. All-in-one kind ones will be the most appreciated but if your suggestion includes more than 3 softwares, please suggest me the ones that work together painlessly. thanks in advance..

• Tracking object entries when "playing" a Windows Enhanced Metafile

  - by lzcd

  One of my current projects requires that I work out what colours are being used in an EMF file. I have been able to successfully whip up a file parser in C# that notes all references to colours... but haven't had any luck tracking which objects are in use across the entire file so I can apart colours that are referenced from colours that are used to paint on screen. The older style WMF files are easy as the object library starts at zero and one can simply track each "Create Object" style command... but EMF files are proving to be trickier as there seems to be preexisting entries in the library (if the "Select Object" commands I'm seeing are to be believed). Would anyone be able to either enlighten me on how to track objects in the library correctly with EMF files... or suggest an easier alternative to work out which colours are actually being used in the file (as opposed to just being defined)?

• chess AI for GAE

  - by Richard

  I am looking for a Chess AI that can be run on Google App Engine. Most chess AI's seem to be written in C and so can not be run on the GAE. It needs to be strong enough to beat a casual player, but efficient enough that it can calculate a move within a single request (less than 10 secs). Ideally it would be written in Python for easier integration with existing code. I came across a few promising projects but they don't look mature: http://code.google.com/p/chess-free http://mariobalibrera.com/mics/ai.html

• How Should I Print Documentation from Google Code?

  - by peter.newhook

  Google does a decent job of documenting their API (like Closure http://code.google.com/closure/compiler/docs/overview.html) but I find it hard to read because it's broken into such short pages. I like to leaf through my docs and read it on paper. Has anyone found a good way to print from the documentation on Google Code. It could be a PDF, or even just a long page with lots of content. Please note, I'm not talking about the Wikis in the Open Source side of Google Code. I'm referring to the API docs published by Google.

• SQL CE not loading from network share

  - by David Veeneman

  I installed VS 2010 RC yesterday, and suddenly, SQL Server CE isn't loading files from a network share. In projects compiled with VS 2008, if I try to open a SQL CE file located on a network share, I get an error that reads like this: Internal error: Cannot open the shared memory region. If I try to create a data connection in VS 2010 to a SQL CE file on a network share, I get this error: SQL Server Compact does not support opening database files on a network share. Can anyone shed any light on what's going on? Thanks.

• TCP Flow control in AS3?

  - by Jeremy Stanley

  I am currently working on a Flash socket client for a pre-existing service/standard. The service uses TCP flow control to throttle itself and the Flash socket is reading in everything as fast as it can despite not being able to process it as fast as it's being taken in. This causes the bytesAvailable on the socket to keep increasing and the server never knows that the client has fallen behind. In short, is there any way to limit the size of bytesAvailable for a Flash Socket object or throttle it in some other way? Note: Rewriting the server isn't a viable option at the current time as it's a standard and the client's utility drops immensely if server-side changes are needed

• GAE datastore eager loading in python api

  - by tomus

  I have two models in relation one-to-many: class Question(db.Model): questionText = db.StringProperty(multiline=False) class Answer(db.Model): answerText = db.StringProperty(multiline=False) question = db.ReferenceProperty(Question, collection_name='answers') I have front-end implemented in Flex and use pyamf to load data. When i try to load all answers with related questions all works as desired and I can access field answer.question however in case of loading questions (e.g. by Questions.all() ), 'question.answers' remains empty/null (though on server/python side I can revise question.answers without problem - probably after lazy-loading). So is it possible to load all questions along with answers ? (I know this is possible in JPA Java api but what about python ?) Shoud I use additional setting, GQL query or django framework to make it work ?

• Why use MVVM???

  - by LnDCobra

  Okay, I have been looking into MVVM pattern, and each time I have previously tried looking into it, I gave up for a number of reasons: Unnecessary Extra Long Winded Coding No apparent advantages for coders (no designers in my office. Currently only myself soon to be another coder) Not a lot of resources/documentation of good practices! (Or at least hard to find) Cannot think of a single scenario where this is advantageous. I'm about to give up on it yet again, and thought I'd ask to see if someone answer the reasons above. I honestly can't see an advantage of using this for a single/partner coding. Even in complex projects with 10's of windows. To me the DataSet is a good enough view and binding like in the answer by Brent following question

• getting JSlider bar to move on mouse click event

  - by Aly

  Hi, I have a JSlider which shows bet sizes (for a poker game) I am trying to achieve the effect that when a mouse click occurs the slider jumps forward by a bet amount (i.e. a big blind amount) rather than just incrementing by one. If the mouse click happens to the left of the bar i want it to decrement by a fixed amount else increment. I looked into attaching a mouse listener, but do not know how I can use the event to find out on what side of the bar the mouse was clicked. Any ideas?

• jQuery not replacing text in ReportViewer

  - by firedrawndagger

  I'm trying to replace text that I got back in the ReportViewer using jQuery. My div, wrapped in the table cell, display "empty" as text - which I plan on replacing with my own formatted text on the client side. I can use jQuery just fine to set a class on the div (which is inside a td element). Example: jQuery('div:contains("empty")').addClass('replacetext'); But for some reason I cannot do this: jQuery('div:contains("empty")').replaceWith('<div>Hello World</div>'); I tried this out on some other elements on the page and jQuery does work... but it seems like this issue is ReportViewer (I'm using 2008) specific.

• Plot hex tiles with different length sides?

  - by Phil

  I'm trying to create a basic grid of hex tiles. I found some code... s=h/Math.cos(30*Math.PI/180)/2; tile._x=x*s*1.5; tile._y=y*h+(x%2)*h/2; That does just that, but I think it's setup for hex's that have same length sides. However my hex has different length sides. It's width is 140 and it's height is 80. I could completely change the code to work with my side lengths, but I was wondering if there's a better way of doing it with the code above.

• .NET WPF Application : Loading a resourced .XPS document

  - by contactmatt

  I'm trying to load a .xps document into a DocumentViewer object in my WPF application. Everything works fine, except when I try loading a resourced .xps document. I am able to load the .xps document fine when using an absolute path, but when I try loading a resourced document it throws a "DirectoryNotFoundException" Here's an example of my code that loads the document. using System.Windows.Xps.Packaging; private void Window_Loaded(object sender, RoutedEventArgs e) { //Absolute Path works (below) //var xpsDocument = new XpsDocument(@"C:\Users\..\Visual Studio 2008\Projects\MyProject\MyProject\Docs\MyDocument.xps", FileAccess.Read); //Resource Path doesn't work (below) var xpsDocument = new XpsDocument(@"\MyProject;component/Docs/Mydocument.xps", FileAccess.Read); DocumentViewer.Document = xpsDocument.GetFixedDocumentSequence(); } When the DirectoryNotFoundException is thrown, it says "Could not find a part of the path : 'C:\MyProject;component\Docs\MyDocument.xps' It appears that it is trying to grab the .xps document from that path, as if it were an actual path on the computer, and not trying to grab from the .xps that is stored as a resource within the application.

• What happens when Npgsql connection pool reaches Max

  - by ClearCarbon

  Both the name of the connection string parameter and this blog post - http://fxjr.blogspot.co.uk/2010/04/npgsql-connection-pool-explained.html - lead me to believe that Npgsql wont exceed the MaxPoolSize value set in the connection string. However the docs (http://npgsql.projects.postgresql.org/docs/manual/UserManual.html) say "Max size of connection pool. Pooled connections will be disposed of when returned to the pool if the pool contains more than this number of connections. Default: 20" This suggests that the pool can actually grow larger than MaxPoolSize and it is in fact just a level at which Npgsql starts to aggressively remove connections from the pool as soon as they are returned. I've been searching to try and find an answer but I can find out exactly what happens when you reach MaxPoolSize. Anyone else know? edit: I should add we are using Npgsql 2.0.6.0 due to another dependency being supported only up to that version.

• Adjusting ComboBox DropDown Width in C#

  - by Jim Fell

  Hello. I have this code that adjusts the width of a comboBox drop-down: private void comboBox_DropDown(object sender, EventArgs e) { ComboBox senderComboBox = (ComboBox)sender; int width = senderComboBox.DropDownWidth; Graphics g = senderComboBox.CreateGraphics(); Font font = senderComboBox.Font; int vertScrollBarWidth = (senderComboBox.Items.Count > senderComboBox.MaxDropDownItems) ? SystemInformation.VerticalScrollBarWidth : 0; int newWidth; foreach (string s in ((ComboBox)sender).Items) { newWidth = (int)g.MeasureString(s, font).Width + vertScrollBarWidth; if (width < newWidth) { width = newWidth; } } senderComboBox.DropDownWidth = width; } It works great, except it expands the width of the drop-down to the right, whereas I would prefer it to expand to the left because the comboBox is located on the right side of my form. Any thoughts or suggestions you may have would be appreciated. Thanks.
