• Do you use Scimore SQL database ?

  - by Darian Miller

  There's a database engine that looks amazing for a free tool and that is Scimore. Have you had much experience with it? If so, how does it rate..particularly against Firebird? How resilient/self reliant is it? (Meaning how much downtime/maintenance is expected?) The scale out capabilities also look very interesting. I just downloaded it and have been playing around and so far it looks good. I had been looking for an easy to deploy single-user type embedded database (which Scimore has an option) and was toying with MS SQL Compact Edition and SQLite and remembered this database from a trial a few years ago. (Windows platform) I was about ready to settle in on SQLite but started thinking about other projects which are multi-user and wanted to stick with a single solution...which is why I started looking at Firebird as well.

• Custom Expression in Linq-to-Sql Designer

  - by csharpnoob

  According to Microsoft: http://msdn.microsoft.com/de-de/library/system.data.linq.mapping.columnattribute.expression.aspx It's possible to add expression to the Linq-to-SQL Mapping. But how to configure or add them in Visual Studio in the Designer? Problem, when I add it manual to thex XYZ.designer.cs it on change it will be lost. //------------------------------------------------------------------------------ // <auto-generated> // This code was generated by a tool. // Runtime Version:2.0.50727.4927 // // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. // </auto-generated> //------------------------------------------------------------------------------ This is generated: [Column(Name="id", Storage="_id", DbType="Int")] public System.Nullable<int> id { ... But i need something like this [Column(Name="id", Storage="_id", DbType="Int", Expression="Max(id)")] public System.Nullable<int> id { ... Thanks.

• Problem with ranking of search results in SharePoint 2007 if using the CONTAINS predicate

  - by mythicdawn

  While writing a front-end for the SharePoint Search web service for work, I did some quick testing with the MOSS Search Tool to make sure things were working right under the hood. What I found was that queries composed only of CONTAINS predicates (FREETEXT ones were fine) would have a rank of 1000 for any results that were returned. According to the documentation (http://msdn.microsoft.com/en-us/library/ms544086.aspx): "If the query returns a document because a non–full-text predicate evaluates to TRUE for that document, the rank value is calculated as 1000." Given that the behaviour I am seeing seems to contradict the documentation, is it the case that all queries that use only the CONTAINS predicate will produce ranking like this?

• Google maps spatial reference system

  - by JavaRocky

  What is Google map's spatial reference system using when you enter a lat, long into the maps search bar? I've found hints that it might be WGS84 but after converting to that coordinate system, nothing shows up when i paste the coordinates into the google maps search box. I am converting from GDA MGA 56. Sample: Input MGA56 coords: 336301, 6253363 Expected WGS86 coords: -33.8473340793201, 151.230631835944 I get: 16834916.928327594 -4008321.1020318186 Spatial coord systems: EPSG:28356 for MGA56 EPSG:900913 for WGS86 (google maps) I am using geotools to do the transform: CoordinateReferenceSystem crsMga56 = CRS.parseWKT(mga56); CoordinateReferenceSystem crsGmaps = CRS.parseWKT(gmaps); Coordinate coordinate = new Coordinate(336301, 6253363); Point point = new GeometryFactory().createPoint(coordinate); MathTransform transform = CRS.findMathTransform(crsMga56, crsGmaps); Geometry geometry = JTS.transform(point, transform); I know the transform is not correct, as when i use an online tool it gives me the correct coords. http://www.environment.gov.au/cgi-bin/transform/mga2geo%5Fgda.pl?east=336301&north=6253363&zone=56

• How to Generate Edifact message from a xml ?

  - by Clem

  Hello, I'm currently dealing with customs messages Beans in Java. After filling in the Beans with different values, I want to produce an EDIFACT CUSDEC message corresponding to each message. For each attribute of a message Bean, I have the information to put the attribute in the right place in EDIFACT CUSEDC format. Thus, I am looking for a free tool (a Java API) which could ideally convert my full-filled Bean into an EDIFACT CUSDEC message. I found a commercial solution (not free) there : http://www.datadirect.com/products/edifact-grid/index.ssp And a quick tutorial here : http://biemond.blogspot.com/2008/09/generate-edifact-message-from-xml.html But ... unfortunately it is not free.. Thanks in advance for your help!

• Tutorial for texture mapping a map onto an Open GL ES sphere?

  - by hotpaw2

  I'm not looking for a library or even open source code. I want to learn how to do this on my own. Where do I start to find an online tutorial, a book chapter, or other educational material for generating a polygonal model of a 3D sphere suitable for feeding to Open GL ES on an iPhone, and then mapping the polygons to some sort of 2D map data so I can texture map the sphere? Is there some sort of software tool (blenders? mayan?) with a tutorial on how to do generate this data? Where is the best place to start?

• Is there an IDE that provides code completion for Python

  - by Justin Walgran

  I am quite fond of the Intellisense code completion baked into Microsoft Visual Studio. I find that I only type 2 to 4 characters of any given keyword which drasticaly speeds up my coding. Now that I have been spending time writing some Python code I find myself reaching for ctrl+space. Are there any IDEs that support code completion in Python? I do my python development on a Mac so an OS x tool would be preferable. It seems like the doc string property of Python methods is a perfect match for inline API discovery.

• Open Python shell through SSH

  - by MihaiD

  I'm using this tool to set up a ssh server on Windows. I'm trying to open the standard Python shell through a remote ssh connection but I simply can't get it to work. If I type 'python' in my ssh command line nothing happens, it just seems to wait for more input. My server machine however, shows a new python process running after I do this. Running scripts works fine, though. Do I need to use another Python shell, some other ssh server, some different configs? Thanks

• Inconsistent Loading Times for GeoRSS Overlay Between Firefox and IE

  - by Mark Fruhling

  I have a very simple page built to display a map and overlay a line based on points in a GeoRSS XML file. Here is the publicly accessible file. http://68.178.230.189/georssimport.html Firefox is loading in about 5 secs, which is expected because there are a lot of points to map, but IE (6 & 7) is taking upwards of 45 secs to a minute. What can I do to diagnose what is going on? What is a tool that will show me what is going on? (i.e. Firebug for IE) Thanks, Mark

• Setting minOccurs="0" (required) on web service parameters of type int

  - by Alex Angas

  I have an ASP.NET 2.0 web method with the following signature: [WebMethod] public QueryResult[] GetListData( string url, string list, string query, int noOfItems, string titleField) I'm running the disco.exe tool to generate .wsdl and .disco files from this web service for use in SharePoint. The following WSDL for the parameters is being generated: <s:element minOccurs="0" maxOccurs="1" name="url" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="list" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="query" type="s:string" /> <s:element minOccurs="1" maxOccurs="1" name="noOfItems" type="s:int" /> <s:element minOccurs="0" maxOccurs="1" name="titleField" type="s:string" /> Why does the int parameter have minOccurs set to 1 instead of 0 and how do I change it? I've tried using [XmlElementAttribute(IsNullable=false)] in the parameter declaration without success.

• Are there any open-source / free site analytics solutions that are intranet deployable?

  - by Richard Nichols

  There are plenty of statistics/analytics providers for Internet deployed software (e.g. Google Analytics), but I'm looking for an analytics tool to integrate into a LAN/intranet based web application. I'm aware of AWStats, but I'd prefer something with a design similar to Google Analytics, where a Javascript callback can be embedded into the app and call back to an analytics server. This doesn't require any sort of extra application server configuration and access to run. I'm thinking there's nothing available that isn't proprietary / pay-for, but I'd love to be told I'm wrong!

• How do you write a consistent UI Automation for MS? MSAA & UI Automation don't seem to overlap.

  - by Greg

  Working on a general Automation tool, considering moving from Win32 Message hooks to .net UI Automation, however the feature set of UI Automation doesn't cover all we have in Win32 and still doesn't seem to support all the GUI on Windows. One such example is Windows Live Messenger. Windows Live messenger 2009 is still using the older DirectUIHwnd to draw the gui. This means that you can't use windows messages to send to the controls, because the controls don't have their own HWND. It also seems to defeat the new .net UI Automation framework though the documentation seems to make out as if it can be joined in the UI Automation and Microsoft Active Accessibility document. Looking at MS Accessibility pointed to Active Accessibility 2.0 SDK Tools which showed that MSAA can interact with the contents. Is there some trick to getting the older MSAA technology that UI Automation seems to be trying to replace to actually work with UI Automation? I'd rather not have multiple solutions trying to automate the same windows for windows unlike Windows Live Messenger where each of these techniques is valid and will work.

• Unable to connect to sql database only from asp

  - by Brian

  In a VB6 program: Dim conn As Object Set conn = CreateObject("ADODB.Connection") conn.Open "DRIVER={SQL Server}; Server=(local)\aaa; Database=bbb; UID=ccc; PWD=ddd" In an ASP program: Sub ProcessSqlServer(conn) Set conn = Server.CreateObject("ADODB.Connection") conn.Open "DRIVER={SQL Server}; Server=(local)\aaa; Database=bbb; UID=ccc; PWD=ddd" The VB6 program works, the ASP program does not (see error below). I tried checking the event log for errors, but found nothing. Or more precisely, I did find local an activation permission error, but this was fixed once I added local launch/activation permission for Network Service to the Machine Debug Manager via the component services tool. Error: Microsoft OLE DB Provider for ODBC Drivers error '80004005' [Microsoft][ODBC SQL Server Driver]Timeout expired

• deriving activity diagram-based GUIs and CRUD them with a DB?

  - by Xin Tanaka

  i received a big book full of processes. i was thinking about the end user (they will be lawyers) and decided the best GUI would be showing activity diagrams or business processes. It reminded me Quickbooks and how non-accountants can successfully use it and understand accounting processes. i began doing research before sending my project to a bunch of programmers: is there some open source solution? can i use MS Visio libraries? which UML tool is programable? what about Eclipse and its modeling tools? etc etc the key points here are: relationships between events, artifacts, actors, etc should be stored in a database. processes or steps in a process should be easily modified by updating the database do this sounds too crazy? (should I explain a bit more why it must be programmed this way?)

• Android-iPhone single codebase

  - by Lorenzo

  Is there a way, apart from using HTML and JavaScript on a web control, to have an (almost) single codebase for an application that should run on iOS and Android? The big issue is of course that they use a different language (Java for Android, Objective-C for iOS) for application development. It would be nice to have some sort of meta-language that will be translated in Java and in Objective-C. What about Flash? Adobe wasn't supposed to release a tool to create flash-based apps in iOS?

• Recommended Python publish/subscribe/dispatch module ?

  - by Eli Bendersky

  From PyPubSub: Pypubsub provides a simple way for your Python application to decouple its components: parts of your application can publish messages (with or without data) and other parts can subscribe/receive them. This allows message "senders" and message "listeners" to be unaware of each other: one doesn't need to import the other a sender doesn't need to know "who" gets the messages, what the listeners will do with the data, or even if any listener will get the message data. similarly, listeners don't need to worry about where messages come from. This is a great tool for implementing a Model-View-Controller architecture or any similar architecture that promotes decoupling of its components. There seem to be quite a few Python modules for publishing/subscribing floating around the web, from PyPubSub, to PyDispatcher to simple "home-cooked" classes. Can you recommend a module that works well in most cases ? Which modules have you had positive experience with ? Negative ? Thanks in advance

• ASP.NET with VS 2008 How to Run Root "/" with Local Web Server

  - by harrije

  I want to use the built-in web server for VS 2008 and have it run my web-site project as the top level root "/". Instructions for VS 2005 can be found at: http://weblogs.asp.net/scottgu/archive/2006/12/19/tip-trick-how-to-run-a-root-site-with-the-local-web-server-using-vs-2005-sp1.aspx My problem is with step 3 of the instructions. When the the web-site project node is selected, right click never gives me an option to select a property-grid like that shown under step 3. Nor could I find another way in the menu or tool bar to get the property-grid. I don't know if the UI difference I'm seeing has to do with me using VS 2008 and the instructions are for VS 2005 or what? How do I get the web-site property-grid for VS 2008, or is there an alternative way to get the root setup I want?

• How to release a simple program

  - by Zenya

  What is the best practice for releasing a simple software? Suppose I created a very small simple and useful program or a tool and would like to share it with everyone by uploading it to my web-site. Do I need a license and which one? (I read http://www.gnu.org/ and http://www.fsf.org/ but still cannot decide - there are too many of them.) Do I need to put somewhere a copyright and what is the basic principles of creating "Copyright" string? How can I make a user, who is going to download and install my program, to believe that my program doesn't contain viruses or a malicious code?

• Java: InitialContext.lookup(String) - what should the value o the parametr be?

  - by bguiz

  To instantiate a Stateful Session Bean inside of a JSP/ servlet, I am using: InitialContext ic = new InitialContext(); SomeStateful state = (SomeStateful) ic.lookup("java:comp/env/SomeStatefulBean"); Trial and error had me prefix the name of my EJB with java:comp/env/, so the above works (on Glassfish 2.1). However I want to know what the proper way to obtain this prefix is. Is there a CLI tool or function somewhere in the admin panel that will allow we to examine/ alter this? Is this platform/ application server dependant? Is there a setting within my ear, EJB-jar or war which I can examine or alter for this? (Forgive the beginner question) Thanks!

• Which format does static library (*.lib) files use? Where can I find "Official" specifications of *.

  - by claws

  Just now I found that static libraries in *nix systems, in other words *.a libraries are nothing but archives of relocatables(*.o files) in ar fromat. What about static libraries(*.lib files) in windows? Which format are they in? I found an article: http://www.microsoft.com/msj/0498/hood0498.aspx which explains *.lib file structure. But Where can I find "Official" specifications of *.lib file structure/format? Other than ar.exe of mingw is there any tool from Microsoft which extracts relocatable objects of *.lib & *.a files? EDIT: I wonder why I'm unable to get to this question. If there are no official specifications. Then how does the compiler ('linker' to be more correct) writers work with *.LIB files?

• Accurev SCM

  - by FlySwat

  Does anyone use Accurev for Source Control Management? We are switching (eventually) from StarTeam to Accurev. My initial impression is that the GUI tool is severely lacking, however the underlying engine, and the branches as streams concept is incredible. The biggest difficulty we are facing is assessing our own DIY tools that interfaced with starteam, and either replacing them with DIY new tools, or finding and purchasing appropriate replacements. Additionally, is anyone using the AccuWork component for Issue management? Starteam had a very nice change request system, and AccuWork does not come close to matching it. We are evaluating either using Accuwork, or buying a 3rd party package such as JIRA. Opinions?

• JavaScript socket vs. Flash socket?

  - by Dr.Dredel

  Steve Jobs just posted this article on why Apple rejects Flash... http://www.apple.com/hotnews/thoughts-on-flash/ I agree that javascript and css can be used to replicate some of Flash's animation, though Flash does all sorts of scaling and tweening that is incredibly powerful, and I'm not sure that there's anything comparable in javascript, if there is, I certainly haven't seen it. However, my question is about the socket. Flash has an incredibly powerful openSocket class that allows you to connect to a server and have the server and the client talk back and forth to one another. As far as I know there is no equivalent class in Javascript. Am I mistaken? Is there some secret mystery Ajax class that replicates the openSocket? If not, then that feature alone makes Flash an invaluable tool. I'm interested in all answers though... and yes this IS a programming question! :)

• How to build a Video Broadcaster, which can handle more than 20,000 viewers

  - by Gaurav Srivastava

  I want to broadcast Video from a web cam, over internet. The problem is, the Video will be viewed live by more than 20,000 people (expected). I have a very little experience with Red5 Broadcasting. I did some broadcasting using Red5 and Flash. It works fine for 1 or 2 viewers i.e. it is great for personal chatting/ video conferencing applications. But, when the number of viewers increases, the delay in Broadcasting also increases. I am experiencing a Delay addition of about 0.5 Seconds for every new user who joins the broadcast. Can any one suggest me some, better technologies on which I can work out this Live Broadcasting. I don't want to use http://www.ustream.com; I want to create one of my own, such tool. But thats always the last solution.

• Migrating from Clearcase LT (UCM) to Subversion

  - by user300199

  I am sure this question has been asked hundreds of time and been responded equally. I am trying to get a clear picture of my effort before I embark on this. I want to know if SVNImporter or any other tool out there helps me migrate my UCM VOBs to Subversion repos. I dont mind losing some history. Also please share your strategies if there are no tools out there. I was told by someone that I would have to rebase my view with each baseline from oldest to the newest and incrementally commit that code into Subversion. While this seems to be plain and simple but considering the number of VOBs we have here, this would be a gigantic task for us to do manually. Is there any script out there that I can use to automate this process. Comments please!!! Thanks Gnan
