• Thoughts/Input about Database Design for a CMS

  - by dallasclark

  I'm just about to expand the functionality of our own CMS but was thinking of restructuring the database to make it simpler to add/edit data types and values. Currently, the CMS is quite flat - the CMS requires a field in the database for every type of stored value (manually created). The first option that comes to mind is simply a table which keeps the data types (ie: Address 1, Suburb, Email Address etc) and another table which holds values for each of these data types. Just like how Wordpress keeps values in the 'options' table, PHP serialize would be used to store an array of values. The second option is how Drupal works, the CMS creates tables for every data type. Unlike Wordpress, this can be a bit of an overkill but really useful for SQL queries when ordering and grouping by a particular value. What's everyone's thoughts?

• How do you use kate? Tips/Tricks/Workflow

  - by Roman A. Taycher

  We all seen a bunch of these? Mostly for IDE's but also for vim and emacs. Kate is (only) a text editor (an awesome one) but it has a ton of options plus a number of plugins, so its hard to know all of it well. How do use the Kate text editor? Please share your workflow and help me and others learn some of the cool tricks you use. I'll start I use the built in terminal a lot opening files quickly, and using it as an enhanced haskell repl with ghci (since ghci doesn't allow you all to just put in all kinds of haskell code). Also use split views to quickly compare files (especially different versions of the same file). Also the auto-complete maybe simple(more use for saving typing time then remembering functions) but it works really well for that. Also if You highlight something and hit a start [/{/( it puts it in between brackets rather then replacing it with a bracket(why the hell do a lot of IDEs not have this feature).

• what's a good way to synchronize a sql server 2008 database from a 2005 database automatically?

  - by Keith Nicholas

  Ok, the scenario is... two servers, on completely different parts of the internet. The sql 2008 database just needs to get data updates and schema changes. It doesn't need to send anything to the 2005 database. Basically just suck data and schema as efficiently as possible automatically as a scheduled task. The database is quite huge.... but the changes per day are probablly around 20/30 megabytes of data/ I can't run any of the inbuilt replication on the 2005 database. I've had a wee look at the Sync Framework, I think that might do what I want, but seems a bit painful and requires a bit of work to get going. I'm wondering if there is tooling out there to make this easier? or?? not quite sure what my options are.

• Web service reference location?

  - by Damien Dennehy

  I have a Visual Studio 2008 solution that's currently consisting of three projects: A DataFactory project for Business Logic/Data Access. A Web project consisting of the actual user interface, pages, controls, etc. A Web.Core project consisting of utility classes, etc. The application requires consuming a web service. Normally I'd add the service reference to the Web project, but I'm not sure if this is best practice or not. The following options are open to me: Add the reference to the Web project. Add the reference to the Web.Core project, and create a wrapper method that Web will call to consume the web service. Add a new project called Web.Services, and copy step 2. This project is expected to increase in size so I'm open to any suggestions.

• Calling a method with an instance of derived class of derived generic type

  - by madsbirk

  Okay, so I have classes class B<T> : A<T> class L : K and a method void Method(A<K> a) {...} What I would like to do is this b = new B<L>(); Method(b); //error But it is not possible to b to the correct type. Indeed it is not possible to make this cast A<K> t = new A<L>(); //error I would really like to not have to change the internals of Method. I have no problems making changes to B and/or L. Do I have any options for making some sort of workaround? I guess it should be possible for Method to execute all of its method calls etc. on b, since B derives from A and L derives from K?

• Javascript: Simply change items in another select box?

  - by oni-kun

  I'm developing a registration page and wish to use JS to dynamically choose avatar selection based on gender. Here's what I have so far.. <select name="gender"> <option value="Male">Male </option> <option value="Female">Female </option> </select> And that should update options in this based on gender: <select name="avatar"> <option value="Trainer">Trainer </option> </select> <br /> <img src="images/trainers/male/Trainer.gif" /> I can't wrap my head around example code or concepts, I just need an example of how to fill 2-3 values into the 'avatar' selectbox based on gender, female or male, also how can I make 'Trainer' part of 'Trainer.gif' become dynamic? based on the avatar they choose?

• What are the "cool" use cases for SharePoint?

  - by David

  I went to the Microsoft Visual Studio 2010 launch event in Minneapolis yesterday and was slightly surprised by how much they were trotting out SharePoint and improved SharePoint development in Visual Studio 2010. SharePoint is something I've largely ignored over the years as a web developer and solution architect on a small development team. I was always under the impression that SharePoint was used mostly for intranets in large corporations, and that if you were developing for SharePoint, it meant that a corporate decision had been made to use it and you as a developer probably had few (if any) options. I realize this assumption is probably incorrect. So, what are the "cool" uses for SharePoint? What unique business problems have you solved using it? What could make a developer excited to be working on something for SharePoint?

• Can't use ProcessWindowStyle.Minimized to start Firefox instance minimized?

  - by Rob3C

  I'm having trouble using Process.Start with Firefox. I want to start a new instance of Firefox in a minimized window. The following works fine with Internet Explorer, notepad, etc.: ProcessStartInfo p = new ProcessStartInfo(); p.FileName = "iexplore.exe"; p.Arguments = "http://www.google.com"; p.WindowStyle = ProcessWindowStyle.Minimized; Process.Start(p); This opens IE in a new, minimized window. Good, just what I want. If I try the exact same thing but instead supply Firefox in the p.FileName, it opens Firefox in a "normal" window, rather than minimized. I've tried various changes to arguments, also have tried examining my local Firefox settings (under Tools/Options) with no luck. I'm sure I'm just missing something simple, but can't figure out what it is. If anyone can help me with getting Firefox opened in a minimized state it would be greatly appreciated!

• Wordpress FORCE UPDATE of permalink settings

  - by Scott B

  I've been having issues on creating new wordpress blogs where I'm setting permalinks via script on theme activation. However, even though they appear to be correct when I check the permalink settings in WP, my new pages are throwing 404 errors. The only fix I've found is that I have to go back to permalink options and click "Save Changes", even though, according to the display, I've made no changes to need to save... I'm setting permalinks to /%postname%/ Here's how I'm doing it. if(get_option('permalink_structure')==""){update_option('permalink_structure', '/%postname%/');} That script gets run when my theme is activated. Any ideas why it only partially does the job?

• Imitate database in C

  - by Mohit Deshpande

  I am fairly new to C. (I have good knowledge of C# [Visual Studio] and Java [Eclipse]) I want to make a program that stores information. My first instinct was to use a database like SQL Server. But I don't think that it is compatible with C. So now I have two options: Create a struct (also typedef) containing the data types. Find a way to integrate SQLite through a C header file Which option do you think is best? Or do you have another option? I am kind of leaning toward making a struct with a typedef, but could be pursuaded to change my mind.

• Paypal IPN setup...Ship to Zipcode and auto calculation

  - by Kunal

  Hi I have successfully setup paypal IPN on my site and its working fine. From my paypal account I have set options to ass shipping and tax calculations(only if it's Iowa). But the only issue is, on the paypal checkout page it's asking me to enter the "Ship to Zipcode" manually...if I enter and update only then the net payable is getting updated with the shipping and tax charges. Is there any variable via which I could send the ship to zip code which will work directly on the cart and make it auto calculate the charges and show it? I have tried both "zip" and "address_zip" variables. None of them worked. By the way I have multiple items on my cart so I am using the "cart" transaction type. Thanks in advance for your help.

• jqgrid - edit form field combobox not defaulting to selected row value after first edit

  - by ooo

  i am using jqgrid with asp.net-mvc. I have an edit form (using jqmodal) which works great but for some reason one combobox field doesn't default to the current selected row after the first time i bring up the edit form. the weird thing is that i have many other comboboxes which work fine every time and i don't see any real difference. here is an example of the field that doesn't work: { name: "TechOwner", index: "TechOwner", width: 70, editable: true, edittype: "select", editoptions: { dataUrl: "/Person/GetSelectData" }, editrules: { required: true} }, and here is a field that works fine: { name: "FundingType", index: "FundingType", align: "left", width: 25, editable: true, edittype: "select", editoptions: { dataUrl: "/Project/FundingGetSelectData" }, editrules: { required: true} }, the dropdown is getting populated with all options (including the current selected row option) but its just defaulting to the top item) instead of one that matches the current row. is there anything to look out for here that may cause this behavior?

• Background image of table cell

  - by Shuaib

  Hey guys, Trying to set a background image for a table view cell, tried almost everything but failing. Hoping someone would notice what I am doing wrong. Here is how my current code looks like: static NSString *CustomCellIdentifier = @"listCustomCell"; listCustomCell *cell = (listCustomCell *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"listCustomCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[listCustomCell class]]) cell = (listCustomCell *)oneObject; } cell.backgroundColor = [UIColor clearColor]; UIImageView *backgroundImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"list_selected.png"]]; //[cell setBackgroundView:backgroundImageView]; cell.backgroundView = backgroundImageView; The image won't show up in the background of the cell. All I see is plain white background. Thanks for help.

• shortest path search in a map represented as 2d shapes

  - by joe_shmoe

  Hi, I have a small library of a few shortest path search algorithms. They were developed for simple undirected graphs (the normal representation - vertices and edges). Now I'd like to somehow apply them on a bit different scenario - where the maps are represented as 2-dimensional shapes, connected by shared edges (edges of the polygons, that is). In this scenario, the search can start/end either at a map object or some point (x,y). What would be the best approach? Try to apply the algorithms onto shapes? or try to extract a 'normal' graph out of the shapes (I have preprocessing time available)? Any advice would be much appreciated, as I'm really not sure which way to go, and I don't have enough time (and skill) to explore many options... Thanks a lot

• Zend + Pop Up's balloons on Server Problem

  - by LookUp Webmaster

  Dear Friends from Stackoverflow, Please help me with a problem that i'm having when uploading my project to the server. I'm using pop up's balloons (http://mckay.cshl.edu/balloons.html) for a project using Zend FW and it works fine on my localhost. (I'm using MAMP on MacOSX) but when I upload the webpage to the server, the text inside the balloons is displayed but the images that form the balloon are not, so somehow the js does not recognize the url to the images (the path it's correct, i've checked several times). The server is an Ubuntu 9.04 virtual machine from rackspace.com, running a LAMP server. I'm using the REWRITE function in Apache, so i guess maybe that's the problem. The rewrite configuration is set up using a .htaccess file with the following content: SetEnv APPLICATION_ENV development Options +FollowSymlinks RewriteEngine ON RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule !.(js|ico|txt|gif|jpg|png|css|html)$ index.php Does anyone knows what the problem might be? Best Regards,

• Oauth callback problem

  - by yogsma

  I am using OAuth with google data api. We have a portal only for authorized users. So when users are logged in and if they are accessing calendar page, they will be asked if they want to sync their calendars with google calendar. If yes, they will be redirected for authentication. Once user has granted access, google appends OAuth_Token to the callback URL. the callback URL was that of the page of calendar in portal. This url has its query string options encrypted. But when the redirection happens , it takes back to login page of url. url is like http://aaa.xyz.com/(encrypted part of query string) and after oauth_token is authorized, this url becomes http://aaa.xyz.com/(encrypted part of query string)&oauth_token. So the user sees the login page after redirection instead of original page. How should I handle this in code.

• Issue with SOAPUI: running test for concurrency

  I am trying to test my web service using SOAPUI (the free version). For testing concurrency, I wished to fire concurrent threads from SOAPUI onto the service. But with the options, the thread count increases gradually (even in the burst mode). The machine where SOAPUI is installed is a WinXP machine. Can I actually do the concurrency testing? If so how? Please guide me. I am waiting for your answers and help.

• Which distribution website should I pick for my open-source package?

  - by Frank

  I wrote an open-source software package, which I'd like to publish (using Apache 2 license). I see various options for how/where to publish/host it: Get my own domain and put it there Put it on Sourceforge Put it on Google Code Put it on Freshmeat ...? What are your experiences / recommendations? What's the current trend among software developers? My only requirements are that I ... can add my own logo on the website can put up some documentation there, get a nice URL that is easy to remember get SVN support (I would also be fine with just uploading a tarball for each new version, it just shouldn't force me to use CVS or any other version control system I'm not familiar with) and of course, the site shouldn't take ownership in the code etc. oh, and it should be free (ok, for registering my own domain I'll be willing to pay a little bit)

• Hudson interactive mode:- Is there one?

  - by Rupal Desai

  I'm pretty new to hudson build system. I currently have my builds run from combination of perl/cgi scripts, with ability to start from a browser. What I need is an ability in hudson to checkout a file from perforce (can do that), parse that file (i can write a script for this) and based on the result of the parse give the user ability to choose various different options on what to build (compile). Is this possible? I'm not sure if I should tie together couple of different projects to do this or not? Any ideas on this could be achieved would be very helpful.

• Is there a way to make vim display "virtual characters" before/after regular patterns in the buffer?

  - by Laurence Gonsalves

  Vim has list and listchars options that make vim display "virtual characters" (by which I mean characters that aren't actually in the buffer) in certain situations. For example, you can make trailing spaces look like something else, or add a visible character to represent the newline character. I'd like to be able to enable the display of certain characters either before or after certain regular patterns ((perhaps syntax items). Sort of like syntax highlighting, but instead of just changing the color/styling of characters that are in the buffer, I'd like to display extra characters that aren't in the buffer. For example, I'd like to display a virtual : (colon) after all occurrences of the word "where" that appear at the end of a line. Is this possible, and if so, what is the necessary vimscript to do it?

• How to stop ReSharper from showing error on a lambda expression where Action is expected?

  - by carlmon

  In Silverlight, System.Windows.Threading's Dispatcher.BeginInvoke() takes an Action<T> or a delegate to invoke. .NET allows me to pass just the lambda expression. but ReSharper sees it as an error, saying "Cannot resolve method 'BeginInvoke(lambda expression)'": Dispatcher.BeginInvoke(() => { DoSomething(); }) The error goes away if I explicitly create the Action around the expression like this: Dispatcher.BeginInvoke(new Action<object>(o => { DoSomething(); })); I prefer the least amount of code in this case for the best readability. Is there a way to disable this specific ReSharper error notification? I tried some of the options, but could not find it. Thanks, Carl

• Hibernate cascading: should setting to null on a parent delete children?

  I wonder if Hib works as expected in my case? My Cascading options are set to "all,delete-orphan". Table_A @OneToOne Table_B Table_B @OneToMany Table_C Now it looks like Table_A . getTable_B . getTable_C_Collection() Suppose there are elements in Table_C collection. What I expect from Hibernate: if I set Table_B link to null, then all Table_C collection elements MUST BE DELETED. It does not happen. They become ORPHANED !

• How to write software for my touchpad?

  - by Nona Urbiz

  I have some ideas for improvements on my touchpad, ranging from the run of the mill scroll horizontally at the bottom, tapzones for right click, to more complicated ones. But I have no idea where to get started? I'm working on Windows 7 Home Premium, its an Asus laptop, and I have none of these options natively available to me. Regardless, I want to write something that anyone can use. Where would I start? (it'd be nice to write in c++? is that possible? what are the requirements here? what language would be recommended?)
