  • Solution for social network + marketplace with multiple sellers?

    - by user261231
    I want to build a social network, with some of the users being able to put up some stuff up for sale. So basically, a social network + multiple sellers e-commerce. What is the best technology solution for that? I was thinking of going Rails route, using CommunityEngine and ActiveMerchant. Another option is going PHP and using something like X-Cart, which already has multiple sellers interface. Any recommendations? Thanks!

  • Mercurial Merging only certain changesets

    - by PostMan
    Ok, so we recently converted from SVN to Mercurial. We are using TortoiseHG normally. In our one repository we have all of our projects, C++ / .NET / ASP. We have about 100 projects, all using common library projects. So it would be quite difficult task to create multiple repo's for each project. Now, we have the default branch, and let's say branchA. I'm working on BranchA and adding my uber changes to it, and I change a common library, let's say an extension method I want to commit this to branchA and default, how would I go about this? However, I don't want all my changes from branchA to be merged into default, and I don't want all the other changes from default Hopefully this is sufficient information!

  • Silverlight Canvas doesn't support KeyDown?

    - by chakrit
    I have this: <Canvas x:Name="LayoutRoot" KeyDown="LayoutRoot_KeyDown"> </Canvas> In a newly-minted Ag 3 application in VS2008. I simply changed the default <Grid /> to <Canvas /> and added a KeyDown handler that pops a MessageBox. But no matter how I tried, the KeyDown event just would never, ever fires. Is it simply that <Canvas /> doesn't support KeyDown or am I doing something wrong?

  • rails: actionmailer not logging

    - by bandhunt
    I'm setting up actionmailer in rails but don't see where it logs errors and therefore cannot troubleshoot. I've got the delivery_errors turned on in environments/development.rb: config.action_mailer.raise_delivery_errors = true I'm not seeing anything logged in development.log related to emailing. Does actionmailer log to somewhere else or what am I missing? Thanks!

  • Working around MySQL error "Deadlock found when trying to get lock; try restarting transaction"

    - by Anon Guy
    Hi all: I have a MySQL table with about 5,000,000 rows that are being constantly updated in small ways by parallel Perl processes connecting via DBI. The table has about 10 columns and several indexes. One fairly common operation gives rise to the following error sometimes: DBD::mysql::st execute failed: Deadlock found when trying to get lock; try restarting transaction at Db.pm line 276. The SQL statement that triggers the error is something like this: UPDATE file_table SET a_lock = 'process-1234' WHERE param1 = 'X' AND param2 = 'Y' AND param3 = 'Z' LIMIT 47 The error is triggered only sometimes. I'd estimate in 1% of calls or less. However, it never happened with a small table and has become more common as the database has grown. Note that I am using the a_lock field in file_table to ensure that the four near-identical processes I am running do not try and work on the same row. The limit is designed to break their work into small chunks. I haven't done much tuning on MySQL or DBD::mysql. MySQL is a standard Solaris deployment, and the database connection is set up as follows: my $dsn = "DBI:mysql:database=" . $DbConfig::database . ";host=${DbConfig::hostname};port=${DbConfig::port}"; my $dbh = DBI->connect($dsn, $DbConfig::username, $DbConfig::password, { RaiseError => 1, AutoCommit => 1 }) or die $DBI::errstr; I have seen online that several other people have reported similar errors and that this may be a genuine deadlock situation. I have two questions: What exactly about my situation is causing the error above? Is there a simple way to work around it or lessen its frequency? For example, how exactly do I go about "restarting transaction at Db.pm line 276"? Thanks in advance.

  • Async validation rule in csla

    - by Steve
    Does anyone have a simple example of implementing an async validation rule in csla? I have looked at the example in the Company class in the Rolodex sample but this isn't particularly clear to me: why do I need a command class? I'm using csla 3.8 in a WPF application.

  • Can layouts be chosen by Grails controllers?

    - by maerics
    I'm building a CMS as a learning exercise in Grails and would like to give content managers the ability to choose between different HTML page structures (e.g. 2 column, 3 column, etc). Grails Layouts seem like a logical choice but is it possible for a Grails controller to explicitly name which layout will be used for rendering? Ideally there would be a layout option to the render method, per Ruby on Rails but I don't see anything like it. It seems like it might be possible using the applyLayout method by passing the name of the layout but this requires each GSP page to explicitly request layout (annoying overhead per-page) rather than using Layout by Convention. Any ideas?

  • LINQ compiled query DataBind issue

    - by Brian
    Hello All, I have a pretty extensive reporting page that uses LINQ. There is one main function that returns an IQueryable object. I then further filter / aggregate the returned query depending on the report the user needs. I changed this function to a compiled query, it worked great, and the speed increase was astonishing. The only problem comes when i want to databind the results. I am databinding to a standard asp.net GridView and it works fine, no problems. I am also databinding to an asp.net chart control, this is where my page is throwing an error. this works well: GridView gv = new GridView(); gv.DataSource = gridSource; But this does not: Series s1 = new Series("Series One"); s1.Points.DataBindXY(gridSource, "Month", gridSource, "Success"); The error i receive is this: System.NotSupportedException Specified method is not supported When i look into my gridSource var at run time i see this using a typical linq query: SELECT [t33].[value2] AS [Year], [t33].[value22] AS [Month], [t33].[value3] AS [Calls]...... I see this after i change the query to compiled: {System.Linq.OrderedEnumerable<<>f__AnonymousType15<string,int,int,int,int,int,int,int>,string>} This is obviously the reason why the databindxy is no longer working, but i am not sure how to get around it. Any help would be appreciated! Thanks

  • How do I safely Debug.Assert in ASP.NET?

    - by MatthewMartin
    Asserts can't be caught. This is good because some errors I don't want to be wrapped in try/catch, at least not on the development server. But Asserts seem awefully dangerous. If they get onto production, it can hang the ASP.NET server with a msgbox. //Don't want this on prod even if debug=true is in the web.config #if DEBUG //A future client programmer can wrap this in a try{}catch{} if (!EverythingIsOkay) throw new InvalidOperationException("Dagnabbit, programming error"); //This stops the but has less information that an // Exception and hangs the server if this accidentally // runs on production System.Diagnostics.Debug.Assert(!EverythingIsOkay); #endif Is there better way to communicate an violation of a inviolable condition to a developer without risking hanging IIS? UPDATE: After reading the first replies, I guess the answer hinges on a foolproof way to detect when code is running in a development environment and when it is on a production server, or figuring out how to throw an exception that can't be caught and ignored.

    I have (for example) Dictionary of different generic types (d1, d2, d3, d4) and I want to store them in something var d1 = new Dictionary<int, string>(); var d2 = new Dictionary<int, long>(); var d3 = new Dictionary<DateTime, bool>(); var d4 = new Dictionary<string, object>(); var something = ??? //new List<object> {d1, d2, d3, d4}; Is there any other way how to store that in something with common denominator different than object?

  • A lightweight application framework for PHP?

    - by millenomi
    I have long been a fan of _why's Camping microframework -- lightweight, great for microscopic applications (low concurrency, easy to use and edit and maintain), which is what I do. I'd love to know if there's something similar for PHP; full-blown app frameworks like CakePHP or Symphony are very large for what I do, but I can't seem to find nothing "less". What PHP framework would you prefer, in this situation?

  • Using CSS instead of tables to create a centered column of images

    - by pcampbell
    Consider the task of replacing this table with CSS stylings: <table border="1"> <tr><td align="center"> <img src="foo" /> </td></tr> <tr><td align="center"> <img src="bar" /> </td></tr> <tr><td align="center"> <img src="bat" /> </td></tr> </table> The desired output is 3 images stacked on top of each other. The images are centered on the widest of them all. How would you style this markup with <div> around those <img> tags with CSS to achieve the same look?

  • Add time to a Date object in javascript

    - by baiano
    I am trying to add time to a Date object in javascript but am not getting the results that I am expecting. I am trying to pull a timer off of the page and add it to the current time to get the unix timestamp value of when the timer will hit zero. The time on the page is displayed as " HH:MM:SS ". This is what I have: time=getTimerText.split(":"); seconds=(time[0]*3600+time[1]*60+time[2])*1000; to convert the time into milliseconds. fDate=new Date(); fDate.setTime(fDate.getTime()+seconds); add the milliseconds to the javascript timestamp alert(Math.round(fDate.getTime() / 1000)); convert the javascript timestamp to a unix timestamp Since the timer is counting down I should get the same result every time i run the script, but I don't. Can anyone see what I might be doing wrong here?
