  • WinForms name chooser

    - by PavelR
    I have a set of names (first, last, salutation) and need a control to allow users to select a single name using WinForms. A ComboBox works fine if the there are ~20 names, but not so well when there are 100 names. Can anyone recommend a name picker? Perhaps an address book control that I could customize? It's not too hard to write my own, but I have other wheels to invent.

  • Can someone clarify what this Joel On Software quote means?

    - by Bob
    I was reading Joel On Software today and ran across this quote: Without understanding functional programming, you can't invent MapReduce, the algorithm that makes Google so massively scalable. The terms Map and Reduce come from Lisp and functional programming. MapReduce is, in retrospect, obvious to anyone who remembers from their 6.001-equivalent programming class that purely functional programs have no side effects and are thus trivially parallelizable. What does he mean when he says functional programs have no side effects? And how does this make parallelizing trivial?

  • What's missing in Cocoa?

    - by Bridgeyman
    If you could add anything to Cocoa, what would it be? Are there any features, major or minor, that you would say are missing in Cocoa. Perhaps there is a wheel you have had to invent over and over because of an omission in the frameworks?

  • KISS: Simple C# application which communicates with a RESTful web service.

    - by Workshop Alex
    Following the KISS principle, I suddenly realised the following: In .NET, you can use the Entity Model Framework to wrap around a database. This model can be exposed as a web service through WCF. This web service would have a very standardized definition. A client application could be created which could consume any such RESTful web service. I don't want to re-invent the wheel and it wouldn't surprise me if someone has already done this, so my question is simple: Has anyone already created a simple (desktop, not web) client application that can consume a RESTful service that's based on the Entity Framework and which will allow the user to read and write data directly to this service? Otherwise, I'll just have to "invent" this myself. :-)Problem is, the database layer and RESTful service is already finished. The RESTful service will only stay in the project during it's development phase, since we can use the database-layer assembly directly from the web applications that are build around it. When the web application is deployed, the RESTful services are just kept out of the deployment. But the database has a lot of data to manage over nearly 50 tables. When developing against a local database, we can have straight access to the database so I wouldn't need this tool for this. When it's deployed, the web application would be the only way to access the data so I could not use this tool. But we're also having a test phase where the database is stored on another system outside the local domain and this database is not available for developers. Only administrators have direct access to this database, making tests a bit more complex. However, through the RESTful service, I can still access the data directly. Thus, when some test goes wrong, I can repair the data through this connection or just create a copy of the data for tests on my local system. There's plenty of other functionality and it's even possible to just open the URL to a table service straight in Excel or XMLSpy to see the contents. But when I want to write something back, I have to write special code to do just that. A generic tool that would allow me to access the data and modify it would be easier. Since it's a generic setup around the ADO.NET Data services, this should be reasonable easy too. Thus, I can do it but hoped someone else has already done something similar. But it appears that there's no such tool made yet...

  • 'add another item' in non-CCK Drupal forms

    - by ceejayoz
    CCK for Drupal has the handy feature of allowing a single CCK field to accept multiple values via a "add another item" button that results in an array of data in the node. I'm wondering if there's any easy way of adapting this for a non-CCK form that I'd be calling by drupal_get_form. I'd rather not have to re-invent the wheel with multi-step form techniques. Anyone done this?

  • Does a wrapper class for a COM interop IStream already exist?

    - by AnthonyWJones
    I'm about to write a Wrapper for a COM interop IStream so that code that expects a standard .NET Stream can use it. However it occurs to me that this sort of thing may already have been done before (although I haven't been able to find it myself with web searching). So I'm just putting this out here in case I'm about to re-invent the wheel. Note I've come across code implementing IStream wrapping a .NET stream but I need the reverse.

  • What's the right way to communicate between 2 or more .Net applications running on a same computer w

    - by Ivan
    If my applications run on a same computer or even on different computers in a same LAN and need intense and quick communication, it seems illogical for me to use text-encoded web services and HTTP. I could possibly use IP/TCP/UDP sockets and invent my own protocols, but believe there is a standard way for .Net applications to send/receive object instances (and, maybe, even sharing an object by reference?). Can you tell me what's that standard way? I am only interested in .Net Framework 4 applications and don't need to support legacy frameworks.

  • Auto accept outlook VBA

    - by Russ
    Is there a VB macro or some sort of add-on out there that will allow me to auto accept invitations in outlook by sender or by folder? I was thinking about doing a VB script for this but I don't want to re-invent the wheel?

  • Data Quality Check - SQL Server

    - by user319384
    I am trying to find a good mechanism where I can check whether the data being entered by a group of people is grammatically correct, has correct spellings, etc, etc. I also would like to compute words per minute and accuracy. Is there any process to do this so that I do not have to re-invent the wheel? Thanks in advance.

  • php functions new php developers should be aware of

    - by John
    Can people suggest a list of common or popular php functions that new/junior programmers should be aware of so that they don't "re-invent-the-wheel" so to speak? For example, I've seen a lot of new coders try to write their own date parsing functions when a combination of date(), strtotime() and time() can do everything their looking for. Any other ones you guys want to add to this list? Thanks

  • PHP Compare Two Arrays?

    - by Sjwdavies
    I'm trying to compare two entries in a database, so when a user makes a change, I can fetch both database entries and compare them to see what the user changed, so I would have an output similar to: User changed $fieldName from $originalValue to $newValue I've looked into this and came accross array_diff but it doesn't give me the output format I need. Before I go ahead and write a function that does this, and returns it as a nice $mtextFormatDifferenceString, can anyone point me in the direction of a solution that already does this? I don't want to re-invent the wheel..

  • Parsing language for both binary and character files

    - by Thorsten S.
    The problem: You have some data and your program needs specified input. For example strings which are numbers. You are searching for a way to transform the original data in a format you need. And the problem is: The source can be anything. It can be XML, property lists, binary which contains the needed data deeply embedded in binary junk. And your output format may vary also: It can be number strings, float, doubles.... You don't want to program. You want routines which gives you commands capable to transform the data in a form you wish. Surely it contains regular expressions, but it is very good designed and it offers capabilities which are sometimes much more easier and more powerful. Something like a super-grep which you can access (!) as program routines, not only as tool. It allows: joining/grouping/merging of results inserting/deleting/finding/replacing write macros which allows to execute a command chain repeatedly meta-grouping (lists-tables-hypertables) Example (No, I am not looking for a solution to this, it is just an example): You want to read xml strings embedded in a binary file with variable length records. Your tool reads the record length and deletes the junk surrounding your text. Now it splits open the xml and extracts the strings. Being Indian number glyphs and containing decimal commas instead of decimal points, your tool transforms it into ASCII and replaces commas with points. Now the results must be stored into matrices of variable length....etc. etc. I am searching for a good language / language-design and if possible, an implementation. Which design do you like or even, if it does not fulfill the conditions, wouldn't you want to miss ? EDIT: The question is if a solution for the problem exists and if yes, which implementations are available. You DO NOT implement your own sorting algorithm if Quicksort, Mergesort and Heapsort is available. You DO NOT invent your own text parsing method if you have regular expressions. You DO NOT invent your own 3D language for graphics if OpenGL/Direct3D is available. There are existing solutions or at least papers describing the problem and giving suggestions. And there are people who may have worked and experienced such problems and who can give ideas and suggestions. The idea that this problem is totally new and I should work out and implement it myself without background knowledge seems for me, I must admit, totally off the mark.

  • Are there algorithms for increasing resolution of an image?

    - by David
    Are there any algorithms or tools that can increase the resolution of an image - besides just a simple zoom that makes each individual pixel in the image a little larger? I realize that such an algorithm would have to invent pixels that don't really exist in the original image, but I figured there might be some algorithm that could intelligently figure out what pixels to add to the image to increase its resolution.

  • True or False: Good design calls for every table to have a primary key, if nothing else, a running i

    - by Velika
    Consider a grocery store scenario (I'm making this up) where you have FACT records that represent a sale transaction, where the columns of the Fact table include SaleItemFact Table ------------------ CustomerID ProductID Price DistributorID DateOfSale Etc Etc Etc Even if there are duplicates in the table when you consider ALL the keys, I would contend that a surrogate running numeric key (i.e. identity column) should be made up, e.g., TransactionNumber of type Integer. I can see someone arguing that a Fact table might not have a unique key (though I'd invent one and waste the 4 bytes, but how about a dimension table?

  • Good JavaScript engine for animating via Sprite Sheets (not in canvas)

    - by N. Taylor Mullen
    I've looked around a bit for a great JavaScript Sprite Sheet animator lib/engine but couldn't find any good ones so I thought I'd ask around =). What I'm looking for in the engine is: Animate an image in a non-canvas setting (ex: div via css or img tags) Control frame rate/animation speed Flags to loop or to animate once etc. Are there any engines like this out there? If not I can always make my own but then again, I don't want to re-invent the wheel =].

  • Is it possible to use System.Configuration, if there is no local app.config? And how to, if it is po

    - by Aen Sidhe
    Hello. I have a client apllication that run in very restricted area - it has no direct access to computer, where it is running. I don't want to invent another one System.Configuration system to configure my application. But there is no method in ConfigurationManager, that allows to load configuration from string or Stream. It seems to me that it's impossible to use a ConfigurationManager in this particular scenario, but may be (and I hope to) wrong?

  • Contact picker with search function

    - by tiex
    This question1 describes a way how to show list of phone numbers and select one of them if my app needs a phone number. But image if I have a huge contact list, it is not enough to just show list but possibility for filtering (by contact's name) is also needed. Is there a standard way to show phones list with picking possibility and with filtering possibility? (I wouldn't like to invent my own) Is there a solution for the problem for sdk 2.0 and lower?
