  • Single Regex for filtering roman numerals from the text files.

    - by Nains
    I am stuck in between of a problem where only one pass of regular expression is allowed( some old hard code). I need the regex for roman numerals. I have tried the standard one i.e. ^(?i)M*(D?C{0,3}|C[DM])(L?X{0,3}|X[LC])(V?I{0,3}|I[VX])$, but the problem is it allows null( '') values also. Is there any way around to check is problem?

  • Example of a Good Func Spec?

    - by Alex
    Hey, I'm writing my func spec, and I was wondering if there are any good samples of a complete and well-written func spec? Like "This is a standard You're supposed to aspire to" type of spec. I know that Joel has a skeleteon of a func spec on his website, but I am looking for something more complete because I'm not of the appropriate amount of detail, formatting, etc. Thanks, Alex

  • Rails Atom builder xml.tag!("activity:object-type") error

    - by Anup
    I am creating a activity stream of my feeds according to the http://activitystrea.ms standard. I am using rails atom builder to create a valid atom feed, but when I use xml.tag!("activity:object-type", "http://activitystrea.ms/schema/1.0/person") the atom feed goes blank.On seeing the source I find the correct xml format from what I have found out the ":object" is giving the problem.

  • Pretty Printer for T-SQL?

    - by Paul
    I'm looking for a good T-SQL Pretty Printer so that all the code looks consistant between developers in our project. Preferably a free/open source one, but paid for isn't out of the realms of possibility as long as it's reasonably priced. Are there any particular industry leaders? I'm not that fussed about what particular standard it uses, but the more configurable the better. That way we can have little style wars among the developers and have a bit of fun to boot. ;-) I suppose I should add that Visual Studio and Management Studio integration would be considered favourably.

  • Multi-tenant application on Windows Azure

    - by Alexey Zakharov
    Hi guys, We want to create multitenant application with shared database table structure. Currently with standard SQL Server we could achieve that with providing TenantID for each table. Could we achieve the same on Windows Azure, but without TenantIDs? Best regards, Alexey Zakharov

  • .NET: understanding web.config in asp.net

    - by mark smith
    Hi there, Does anyone know of a good link to explain how to use the web.config...... For example, i am using forms authentication... and i notice there is a system.web and then it closed /system.web and then below configuration there are additional location tags here is an example, if you ntoice there is an authentication mode=forms with authorization i presume this is the ROOT....... It is also self contained within a system.web .... Below this there are more location= with system.web tags.... I have never really understand what i am actually doing.. I have tried checkign the MSDN documentation but still i don't fully understand up.... Can anyone help? If you notice with my example.... everything is stored in 1 web.config... i thought the standard waas create a standard web.config and then create another web.config in the directory where i wish to protect it..??? <configuration> <system.web> <compilation debug="true" strict="false" explicit="true" targetFramework="4.0" /> <authentication mode="Forms"> <forms loginUrl="Login.aspx" defaultUrl="Login.aspx" cookieless="UseCookies" timeout="60"/> </authentication> <authorization> <allow users="*"/> </authorization> </system.web> <location path="Forms"> <system.web> <authorization> <deny users="?"/> <allow users="*"/> </authorization> </system.web> </location> <location path="Forms/Seguridad"> <system.web> <authorization> <allow roles="Administrador"/> <deny users="?"/> </authorization> </system.web> </location>

  • Need to change the default browser for an MVC2 project

    - by schefdev
    I just created my first MVC2 project using the standard template. I need to be able to change the default browser for my project to test in IE (I use chrome as the default on my OS). Unfortunately, the "right click on default.aspx" suggestion which worked in MVC1 can't work with these new projects as they don't have that file. I'm sure I'm overlooking something simple... Thanks.

  • What is the current choice for doing RPC in Python?

    - by edomaur
    Actually, I've done some work with Pyro and RPyC, but there is more RPC implementation than these two. Can we make a list of them? Native Python-based protocols: PyRo (Python Remote Objects) RPyC (Remote Python Call) Circuits JSON-RPC based frameworks: python-symmetric-jsonrpc rpcbd XML-RPC based frameworks: XMLRPC, using the xmlrpclib and SimpleXMLRPCServer modules in the standard library. Others? Twisted Spread

  • Best practices book for CRUD apps

    - by Kevin L.
    We will soon be designing a new tool to calculate commissions across multiple business units. This new compensation scheme is pretty clever and well thought-out, but the complexity that the implementation will involve will make the Hubble look like a toaster. A significant portion of the programming industry involves CRUD apps; updating insurance data, calculating commissions (Joel included) ...even storing questions and answers for a programmer Q&A site. We as programmers have Code Complete for the low-level formatting/style and Design Patterns for high-level architecture (to name just a few). Where’s the comparable book that teaches best practices for CRUD?

  • WinForms: Control ListView checkbox painting

    - by Telanor
    It seems that the checkbox used in a ListView when CheckBoxes = true isn't a proper checkbox. It doesn't draw the MouseOver or MouseDown state and it doesn't support the Indeterminate/Intermediate state. How can I replace the checkbox with a standard checkbox control or take control of the drawing of just the checkbox so I can use the CheckBoxRenderer class?

  • In WPF, What is the best way to create toolbar buttons so that the images are properly scaled?

    - by T.R.
    Specifically, I'm looking to use the 16*16 32-bit png images included with the VS2008ImageLibrary. I've tried manually setting the Height and Width attributes of the image, adjusting margins and padding, adjusting Stretch and RenderOptions. My attempts to create toolbar buttons have all led to either Improper Scaling (blurry icons), the bottom row of pixels on the icon being truncated, or the toolbar button being improperly sized - not to mention the disappearing icons already mentioned Here. Has anyone found the best way to make standard, VisualStudio/WinForms-style toolbar buttons that display properly in WPF?

  • remote desktop client with panning of large desktops?

    - by mikewse
    When using the standard Windows remote desktop client to connect to a large remote desktop, the result is usually that the remote desktop is resized to a smaller size matching the local display. Are there any RDP clients that instead leave the remote desktop at its original size and pan this larger area when the mouse reaches the border edges of the local display? Thanks Mike

  • OracleClient to devart dotConnect for Oracle

    - by lex9081
    Has anyone tried migration from Microsoft OracleClient to dotConnect for Oracle? Is it realy so easy (as they wrote at their blog http://www.devart.com/blogs/dotconnect/?p=67) or just another marketing trick? I've tried ODP.NET, but it seems to me that its interface differs from the standard one.

  • TDD, DDD and the No-getters principle

    - by Justin
    Hi all, After several years of following the bad practice handed down from 'architects' at my place of work and thinking that there must be a better way, I've recently been reading up around TDD and DDD and I think the principles and practices would be a great fit for the complexity of the software we write. However, many of the TDD samples I have seen call a method on the domain object and then test properties of the object to ensure the behaviour executed correctly. On the other hand, several respected people in the industry (Greg Young most noticeably so) advocate the "no-getters" principle on our domain objects. My question therefore is: How does one test the functionality of a domain object if it is forbidden to retrieve its state? I believe I am missing something fundamental so please feel free to call me an idiot and enlighten me - any guidance would be greatly appreciated.

  • Trim a string in C

    - by Orion Edwards
    Briefly: I'm after the equivalent of .NET's String.Trim in C using the win32 and standard C api (compiling with MSVC2008 so I have access to all the C++ stuff if needed, but I am just trying to trim a char*). Given that there is strchr, strtok, and all manner of other string functions, surely there should be a trim function, or one that can be repurposed... Thanks

THe goal is if a depdendency cannot be found in the outter container then i would like to then search the inner container. How can i achieve this ? I would prefer to do things in a standlike manner, without reverting to use of non standard WELD extensions.

  • UITextView insert text in the textview text

    - by John Smith
    I want to have to occasionally insert text into the UITextView text object. For example, if the user presses the "New Paragraph" button I would like to insert a double newline instead of just the standard single newline. How can I go about such? Do i have to read the string from UITextView, mutate it, and write it back? Then how would I know where the pointer was? Thanks

  • mysql, sqlite database source code

    - by Yang
    hi guys, i know implementing database is a huge topic, but i want to have a basic understanding of how database systems works (e.g. memory management, binary tree, transaction, sql parsing, multi-threading, partitions, etc) by investigating the source code of the database, since there are a few already proven very robust open source databases like mysql, sqlite and so on. however, the code are very complicated and i have no clue where to start. also i find that the old school database textbooks are only explaining the theory, not the implementation details. Can anyone suggest how should i get started and is there any books that emphasis on the technology and techniques of building dbms used in modern database industry? Thank in advance!

  • Executing Custom Actions immediately in WIX

    - by jbloomer
    Is there any way to execute a custom action in WIX as soon as the first dialog (welcome) appears? The requirement is to check prerequisites, and some of those require a custom action. The custom action could be executed as we click to the next dialog, but then the standard WIX prereqs are determined apart from our custom prereq. (The custom action we need is to check that IIS 6 Metabase Compatibility is turned on and a registry search does not work on x64 machines with a 32-bit installer)
