• Getting an odd error, MSSQL Query using `WITH` clause

  - by Aren B

  The following query: WITH CteProductLookup(ProductId, oid) AS ( SELECT p.ProductID, p.oid FROM [dbo].[ME_CatalogProducts] p ) SELECT rel.Name as RelationshipName, pl.ProductId as FromProductId, pl2.ProductId as ToProductId FROM ( [dbo].[ME_CatalogRelationships] rel INNER JOIN CteProductLookup pl ON pl.oid = rel.from_oid ) INNER JOIN CteProductLookup pl2 ON pl2.oid = rel.to_oid WHERE rel.Name = 'BundleItem' AND pl.ProductId = 'MX12345'; Is generating this error: Msg 319, Level 15, State 1, Line 5 Incorrect syntax near the keyword 'with'. If this statement is a common table expression, an xmlnamespaces clause or a change tracking context clause, the previous statement must be terminated with a semicolon. On execution only. There are no errors/warnings in the sql statement in the managment studio. Any ideas?

• Render only the segment/area of a circle that intersects the main circle

  - by Greenhouse Gases

  I absolutely love maths (or 'math' as most of you would say!) but I haven't done it to a level where I know the answer to this problem. I have a main circle which could have a centre point at any x and y on a display. Other circles will move around the display at will but at any given call to a render method I want to render not only those circles that intersect the main circle, but also only render the segment of that circle that is visible inside the main circle. An analogy would be a shadow cast on a real life object, and I only want to draw the part of that object that is 'illuminated'. I want to do this preferably in Java, but if you have a raw formula that would be appreciated. I wonder how one might draw the shape and fill it in Java, I'm sure there must be some variation on a polyline with arcs or something? Many thanks

• Building path independent mod_rewrite statements for generic .htaccess file

  - by Pekka

  Say I have three small web applications stored under a shared web root: www.example.com/app1/ www.example.com/app2/ www.example.com/app3/ www.example.com/app4/ each application has a .htaccess file containing some run-off-the-mill mod_rewrite statements to rewrite urls like RewriteCond %{REQUEST_URI} ^/app1/([^/]+)/([^/]+)\.html$ RewriteRule .* /app1/index.php?selectedProfile=%1&match=%2&%{QUERY_STRING} now, I would like to have a generic .htaccess file in each /app{n} directory. So, no RewriteBase and no /app{n} prefix in the RewriteConds. One idea I had was making the first level a wildcard directory as well: RewriteCond %{REQUEST_URI} ^/([^/]+)/([^/]+)/([^/]+)\.html$ seeing as the .htaccess file gets triggered only when the /app{n} directory is entered, this should work. Is this an acceptable solution? Are there other, better ones?

• ASP.NET connection pool question

  - by James Evans

  Does the same connection string used on two different physical servers hosting different web applications that talk to the same database draw connections from the same connection pool? Or are pooled connections confined to at the application level? I ask because I inherited a 7 year old .NET 1.1 web application which is riddled with in-line SQL, unclosed and undisposed sql connection and datareader objects. Recently, I was tasked to write a small web app that is hosted on another server and talks to the same database and therefore used the same database connection string. I created a LINQ object to read and write the one table required by the app. Now the original .NET 1.1 app is throwing exceptions like "Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached." Maybe these are unreleated, but wanted to get your opinions to make sure I cover all my bases. Thanks!

• Any way to select without causing locking in MySQL?

  - by Shore

  Query: SELECT COUNT(online.account_id) cnt from online; But online table is also modified by an event, so frequently I can see lock by running show processlist. Is there any grammar in MySQL that can make select statement not causing locks? And I've forgotten to mention above that it's on a MySQL slave database. After I added into my.cnf:transaction-isolation = READ-UNCOMMITTED the slave will meet with error: Error 'Binary logging not possible. Message: Transaction level 'READ-UNCOMMITTED' in InnoDB is not safe for binlog mode 'STATEMENT'' on query So, is there a compatible way to do this?

• WCF 4: Fileless Activation Fails On XP (IIS 5) that has SSL port enabled.

• How Do SMS Gateways Work?

  - by Nick

  I've been looking at systems such as txtlocal, esendex and clickatell. I need to send out a very large number of messages and ideally would like to go in at a lower level then using systems like these. Does anyone know how these SMS gateways like I've listed work in terms of actually sending out the messages? Will they have agreements with different carriers and be sending them out programmatically? I've tried contacting some UK carriers directly but as of yet haven't had any success getting any information from them.

• Stack trace in website project, when debug = false

  - by chandmk

  We have a website project. We are logging unhanded exceptions via a appdomain level exception handler. When we set debug= true in web.config, the exception log is showing the offending line numbers in the stack trace. But when we set debug = false, in web.config, log is not displaying the line numbers. We are not in a position to convert the website project in to webapplication project type at this time. Its legacy application and almost all the code is in aspx pages. We also need to leave the project in 'updatable' mode. i.e. We can't user pre-compile option. We are generating pdb files. Is there anyway to tell this kind of website projects to generate the pdb files, and show the line numbers in the stack trace?

• Speeding up CakePHP

  - by DavidYell

  I've been a keen fan and user of CakePHP for about 2.5 years now, but the main bugbear that most fellow developers level at the framework is that it's slow, and the dispatch cycle takes too long to make it a viable solution for production environments. I'm hoping that this question will inspire people to share their tips, tricks and hacks for speeding up CakePHP performance. The blog post I most often refer to is here, http://www.pseudocoder.com/archives/8-ways-to-speed-up-cakephp-apps Which has great tips, but there must be more out there! So please feel free to share your thoughts on making this excellent framework that much more nimble!

• Emacs enum indentation

  - by Masterofpsi

  I'm having a problem with Emacs's indentation of Java enums. While it indents the first member OK, it wants to give all of the rest of the static enum members an additional level of indentation. It looks like this: class MyClass { public enum MyEnum { ONE(1), //good TWO(2), // not good! THREE(3), FOUR(4); private final int value; } } When I run C-c C-s on the line that opens the enum, it gives me ((inclass 1) (topmost-intro 1)), which doesn't seem quite right -- it seems like it should be giving brace-list-open. When I run it on the first enum member, it gives me ((defun-block-intro 21)), which is definitely not right. Every subsequent member gives (statement-cont 50). I'm in java-mode and I'm using the java style of indentation. Does anyone know what the problem might be?

• How do I send a PDF in a MemoryStream to the printer in .Net?

  - by Ryan ONeill

  I have a PDF created in memory using iTextSharp and contained in a MemoryStream. I now need to translate that MemoryStream PDF into something the printer understands. I've used Report Server in the past to render the pages to the printer format but I cant use it for this project. Is there a native .Net way of doing this? For example, GhostScript would be OK if it was a .Net assembly but I don't want to bundle any non .Net stuff along with my installer. The PrintDocument class in .Net is great for sending content to the printer but I still need to translate it from a PDF stream into GDI at the page level. Any good hints? Thanks in advance Ryan

• Requirements of an issue/bug tracker

  - by James Brooks

  I've been looking at various issue/bug trackers available on the net. There are some very good ones, but I'm unable to use them as my server does not support Perl/Ruby (for example), I'm not too bothered however because I am able to write code in PHP and as such would prefer something in that language. So I've taken it upon myself to write a custom issue tracker system. As of now it's in early planning stages, and before I continue, I'd like to find out what people need from such an application. My current list of things to add include: Creating/Editing/Deleting issues - both on user and admin level Related issues (similar to that of STO) Admins will be able to create builds/milestones and version control of projects Admins will be able to assign users/groups to a project Roadmap of projects Possible SVN integration with Git? What do you think? There are a couple more things I'd like to add, but I'm sure you'll think of a better way of adding such feature. What would you like to see from an issue tracker?

• What should I really release as open source when I use Berkeley DB (JE)?

  - by Ersin Er

  The Berkeley DB (JE) license information says: "...Redistributions in any form must be accompanied by information on how to obtain complete source code for the DB software and any accompanying software that uses the DB software.... For an executable file, complete source code means the source code for all modules it contains. It does not include source code for modules or files that typically accompany the major components of the operating system on which the executable file runs." If I build an abstraction level on top of BDB JE, should I open source only that library or any software that uses BDB JE indirectly?

• Best design for generating code from an AST?

  - by Sam Washburn

  I'm working on a pretty complex DSL that I want to compile down into a few high level languages. The whole process has been a learning experience. The compiler is written in java. I was wondering if anyone knew a best practice for the design of the code generator portion. I currently have everything parsed into an abstract syntax tree. I was thinking of using a template system, but I haven't researched that direction too far yet as I would like to hear some wisdom first from stack overflow. Thanks!

• C++: ifstream::getline problem

  - by Jay

  I am reading a file like this: char string[256]; std::ifstream file( "file.txt" ); // open the level file. if ( ! file ) // check if the file loaded fine. { // error } while ( file.getline( string, 256, ' ' ) ) { // handle input } Just for testing purposes, my file is just one line, with a space at the end: 12345 My code first reads the 12345 successfully. But then instead of the loop ending, it reads another string, which seems to be a return/newline. I have saved my file both in gedit and in nano. And I have also outputted it with the Linux cat command, and there is no return on the end. So the file should be fine. Why is my code reading a return/newline? Thanks.

  Hi I'm using the following code to cache objects. HttpRuntime.Cache.Insert("Doc001", _document); HttpRuntime.Cache.Remove("Doc001"); I would like to know were the cache is stored? (On the client PC or the IIS server) Is this a save way of cache objects and by adding and removing cache in this way will it influence any of the other clients, say for instance i've got 2 clients connected and both are storing cache "*HttpRuntime.Cache.Insert("Doc001", _document);*" and one client removes the cache, is it only removed on a client level?

• Finding the best folder for all users on a Windows machine

  - by reallyjoel

  We are making a game which will add a level editor feature soon. We want the user to be able to put levels he's downloaded in a folder and then play it in the game, without any hassle. So, we're looking for a folder that anybody can find, open, write, read, and is multiuser. On Windows Vista / 7, the folder /Users/Public/ look like a great candidate. However, It's not listed in the .net enum System.Environment.SpecialFolder. I have went through them all, and checked what they yield on different Windows versions, and none live up to my requirements. I did find Environment.SpecialFolder.CommonApplicationData, that kinda works, but that folder is hidden (C:\ProgramData) and I assume most users don't display hidden folders. As it stands now, it looks like we'll have to settle for the personal documents folder, but we'd really like a multi user folder? Anyone have any tips? (Hard coding c:\Users\Public\ is out of the question, it will only work on english systems)

• Which Workflow Engine do you recommend?

  - by Glenn

  I am kicking around the idea of using a workflow engine on this upcoming project. We know that there is a lot of caveats with using a workflow engine and we have a lot of development experience in many platforms so we would be willing to let the choice of workflow engine take precedence over our favorite toolset or developer IDE. We are more interested in internal workflow (i.e. petri net for easily changeable ERP purposes without involving additional coder time) than external workflow (i.e. aggregating SOAP calls into a transaction aware, higher level SOA). Which workflow engine would you recommend? We have superficially looked at offerings by Oracle, Microsoft, and some open source stuff too. It's all very overwhelming so please respond only if you have real life experience with implementing internal workflow.

• NoSql Crash Course/Tutorial

  - by Chris Thompson

  Hi all, I've seen NoSQL pop up quite a bit on SO and I have a solid understanding of why you would use it (from here, Wikipedia, etc). This could be due to the lack of concrete and uniform definition of what it is (more of a paradigm than concrete implementation), but I'm struggling to wrap my head around how I would go about designing a system that would use it or how I would implement it in my system. I'm really stuck in a relational-db mindset thinking of things in terms of tables and joins... At any rate, does anybody know of a crash course/tutorial on a system that would use it (kind of a "hello world" for a NoSQL-based system) or a tutorial that takes an existing "Hello World" app based on SQL and converts it to NoSQL (not necessarily in code, but just a high-level explanation). I see this having one solid answer, but if you guys feel like it should be community wiki, I'll be happy to change it. Thanks! Chris

• Closing an EDM ObjectContext?

  - by David Veeneman

  I am getting started with the ADO.NET Entity Framework 4.0. I have created an EDM and data store for the app, and it successfully retrieves entities. The application holds the EDM's ObjectContext as a member-level variable, which it uses to call ObjectContext.SaveChanges(). So far, so good. I am going to refactor to repositories later. Right now, my question is a bit more basic: When I am finished with the EDM, what do I need to do to release it? Is it as simple as calling Dispose() on the ObjectContext? Thanks for your help.
