• Having trouble with match wildcards in array

  - by Senthil

  I've a master text file and exceptions file and I want to match all the words in exception file with master file and increase counter, but the trick is with wildcards. I'm able to do without wildcards with this: words = %w(aaa aab acc ccc AAA) stop = %q(/aa./) words.each do |x| if x.match(/aa./) puts "yes for #{x}" else puts "no for #{x}" end end = yes for aaa yes for aab no for acc no for ccc yes for AAA Also which would be the best way to go about this, using arrays or some other way. Edit: Sorry for the confusion. Yes stop has multiple wildcards and I want to match all words based on those wildcards. words = %w(aaa aab acc ccc AAA) stop = %q(aa* ac* ab*) Thanks

• SQL Max Group By Query Help

  - by Hcabnettek

  Hi All, I have a quick question. How do I select the two values I need in one query? Currently I'm doing this, which works fine, but it's obviously running two queries when one should do the trick. I tried MAX(columnA) and GROUP BY ColumnB, but that returns multiple row. I only want one row returned. DECLARE @biID bigint , @dtThreshold DateTime SELECT @biID = MAX(biID) FROM tbPricingCalculationCount WITH (NOLOCK) SELECT @dtThreshold = dtDateTime FROM tbPricingCalculationCount WITH (NOLOCK) WHERE biID = @biID I would like both those variables to be set correctly in one query. How can I do that? Thanks, ~ck

• PHP PDO MySQL IN (?,?,?...

  - by nute

  I want to write a MySQL statement like: SELECT * FROM someTable WHERE someId IN (value1, value2, value3, ...) The trick here is that I do not know ahead of time how many values there will be in the IN(). Obviously I know I can generate the query on the go with string manipulations, however since this will run in a loop, I was wondering if I could do it with a PDO PreparedStatement. Something like: $query = $PDO->prepare('SELECT * FROM someTable WHERE someId IN (:idList)'); $query->bindValue(':idList', implode(',', $idArray)); Is that possible?

• One pass multiple whitespace replace to single whitespace and eliminate leading and trailing whitesp

  - by Phoenix

  void RemoveSpace(char *String) { int i=0,y=0; int leading=0; for(i=0,y=0;String[i]!='\0';i++,y++) { String[y]=String[i]; // let us copy the current character. if(isspace(String[i])) // Is the current character a space? { if(isspace(String[i+1])||String[i+1]=='\0'||leading!=1) // leading space y--; } else leading=1; } String[y]='\0'; } Does this do the trick of removing leading and trailing whitespaces and replacing multiple whitespaces with single ones ?? i tested it for null string, all whitespaces, leading whitespaces and trailing whitespaces. Do you think this is an efficient one pass solution ??

• Hot to trigger saved password autofill in browsers?

  - by Aleksander Kmetec

  I have a web application written in pure JavaScript (no pre-generated HTML except for the document which loads all the JS files). This app contains a login form which is created dynamically when the document.ready event event is triggered. I trick the browser into displaying the "Remember password?" dialog by posting the login form into a hidden iframe before logging in using ajax (in Firefox the password appears on the saved password list, so this part obviously works) but saved passwords never get filled in after the login screen is loaded again at a later time. The same thing happens in Firefox and Safari. Is there something I can do or some function I can call to trigger autofill?

• Installing a COM object without privileged access for use in Microsoft Office

  - by bmargulies

  Start with a series of MS Office extensions built in C++ as COM objects. Add a user who really badly wants to avoid the requirement of an installer with the necessary privileges to write to HKEY_CLASSES_ROOT. I've seem bits of evidence that MS has created some sort of trick for shadowing HKEY_CLASSES_ROOT from HKCU. Is this, in fact, possible? If so, can this be installed as a non-privileged MSI, or does it have to be arranged otherwise? And, finally, what's the minimum version of Windows required?

• Embedding a File Explorer instance in a WinForms app form

  - by Unsliced

  My (C#, .NET 3.5) app generates files and, in addition to raising events that can be caught and reacted to, I want to display the target folder to the user in a form. The file-list is being shown within the same form as other information. I'm using an instance of the WebBrowser control (System.Windows.Forms.WebBrowser), then navigating to the folder. This shows some default view of the explorer window, with the file summary panel on the left and the files in the 'Tiles' (large icon and text) view. e.g. wb.Navigate(@"c:\path\to\folder\"); I'd like to suppress the panel and to view the file list in the Details view. The user can get to this via a right-click, context menu, but I'd like it to come up automatically. I'd rather not have to build my own TreeView, DataGridView or whatever; the WebBrowser control does all the updating and re-sorting and whatnot 'for free'. Does anybody have a better suggestion? A different control to use or some additional arguments to pass to the control? And if I could trap events (e.g. files being selected/renamed/double-clicked, etc.) then all the better!

• Tricks to avoid losing motivation?

  - by AareP

  Motivation is a tricky thing to upkeep. Once I thought that ambitious projects will keep programmer motivated, and too simple tasks will hinder his motivation. Now I have plenty of experience with small and large projects, desktop/web/database programming, c++/c#/java/php languages, oop/non-oop paradigms, day-job/free-time programming.. but I still can't answer the question of motivation. Which programming tasks I like, and which don't? It seems to depend on too many variables. One thing remains constant though. It's that starting everything from scratch is always more motivating than extending some existing system. Unfortunately it's hard to use this trick in productive programming. :) So my question is, what tricks programmer can use to stay motivated? For example should we use pen and paper as much as possible, in order not to get fed up with monitor and keyboard?

• T-SQL IsNumeric() and Linq-to-SQL

  - by cdonner

  I need to find the highest value from the database that satisfies a certain formatting convention. Specifically, I would like to fund the highest value that looks like EU999999 ('9' being any digit) select max(col) will return something like 'EUZ...' for instance that I want to exclude. The following query does the trick, but I can't produce this via Linq-to-SQL. There seems to be no translation for the isnumeric() function in SQL Server. select max(col) from table where col like 'EU%' and 1=isnumeric(replace(col, 'EU', '')) Writing a database function, stored procedure, or anything else of that nature is far down the list of my preferred solutions, because this table is central to my app and I cannot easily replace the table object with something else. What's the next-best solution?

• Is there a calculator with LaTeX-syntax?

  - by Jørgen Fogh

  When I write math in LaTeX I often need to perform simple arithmetic on numbers in my LaTeX source, like 515.1544 + 454 = ???. I usually copy-paste the LaTeX code into Google to get the result, but I still have to manually change the syntax, e.g. \frac{154,7}{25} - (289 - \frac{1337}{42}) must be changed to 154,7/25 - (289 - 1337/42) It seems trivial to write a program to do this for the most commonly used operations. Is there a calculator which understand this syntax? EDIT: I know that doing this perfectly is impossible (because of the halting problem). Doing it for the simple cases I need is trivial. \frac, \cdot, \sqrt and a few other tags would do the trick. The program could just return an error for cases it does not understand.

• The subscription model behind CSS selectors?

  - by Martin Kristiansen

  With CSS selectors a query string body > h1.span subscribes to a specific type of nodes in the tree. Does anyone know how this is done? Selectors for transformations, how does the browser select the result set? And is there a trick to making it efficient? I imagine there being some sort of hierarchical type-tree for the entire structure to which the nodes subscribe and which is what is used when doing the selector queries — but this is only a guess. Does anyone know the real answer? Or even more interesting, what would be the best way to do dynamic lookups on a tree based on jQuery/CSS search queries?

• Graphviz DOT arrange Nodes in circles, layout too "compact"

  - by Ivo Wetzel

  I'm halfway there please see the edit OK here's my problem, I'm generating a graph of a python module, including all the files with their functions/methods/classes. I want to arrange it so, that nodes gather in circles around their parent nodes, currently everything is on one gargantuan horizontal row, which makes the thing 50k pixels wide and also let's the svg converter fail(only renders about the half of the graph). I went trough the docs(http://www.graphviz.org/doc/info/attrs.html) but couldn't find anything that seems to do the trick. So the question is: Is there a simple way to do this or do I have to layout the whole thing by myself? :/ EDIT: Thanks to Andrews comment I've got the right layout, the only problem now is that it's a bit to "compact"... so the question now is, how to fix this?

• iPhone Provisioning Profile problems...

  - by James

  I have already successfully submitted two apps to the app store, so I should be able to do it by now, right? With my most recent app, however, I'm having a bear of a time with getting the Application Identifier or Bundle Identifier set up. In my distribution profile, I have included the identifier "com.jmock.irowbeta", and then copied it exactly into the the app's Info.plist file under "Bundle Identifier". In the past, this has done the trick, but now I'm getting the error Provisioning profile 'irow beta' specificies the identifier 'com.jmock.irowbeta' which doesn't match the current setting 'com.yourcompany.irow-beta'. So it seems that its somehow still using the default of com.yourcompany.APPLICATION_NAME, but it shouldn't after I have changed it in the Info.plist, right? I think this means that xcode isn't recognizing that PLIST for some reason, because when I change the name of the icon file, for example, or other such attributes, nothing changes. If this is the problem, how do I make xcode recognize the PLIST? Otherwise, what the heck is going on? Thanks, James

• Embedding Facebook Connect In A Facebook Page

  - by Russell C.

  Our site allows users to register using Facebook Connect. We also have a Facebook page. We'd like to include the "Connect with Facebook" button in our page so a user could instantly connect (aka register) and then be forwarded on to their account on our site. I was hoping to use the Static FBML page application and the FBML iFrame tag to simply embed the button but it looks like the iFrame tag isn't allowed in Facebook pages. Facebook Connect uses JavaScript so I'm wondering if there is some kind of trick I could use like popping up a page in a new window that would automatically display the connect dialog box. Any ideas on how I would include a Facebook Connect button on our Facebook page would awesome! Thanks in advance for your help.

• NHibernate illegal access to loading collection error

  - by Rob

  I'm getting the error "Illegal acces to loading collection" when i'm trying to get a list of variants belonging to a certain product. The NHibernate mapping is as below; <list name="Variants" lazy="false" cascade="save-update" inverse="false" table="PluginProduct_ProductVariant"> <key column="ProductId" /> <index column="Ordinal" /> <one-to-many class="Plugin.Product.Business.Entities.Variant, Plugin.Product" /> </list> </joined-subclass> I already tried chancing the laziness and inverse properties as suggested in other topics on this site, but they didn't do the trick.

• TextMate can't find my RSpec gem in opt (from macports)

  - by sbwoodside

  I know I've had this problem before so I'm really frustrated. I've got the Ruby RSpec bundle installed for TextMate, but when I Run Behaviour Description or Run Focused Example I get this wonderful error: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:827: in `report_activate_error': Could not find RubyGem rspec (>= 1.1.0) (Gem::LoadError) from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:261: in `activate' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby /1.8/rubygems.rb:68:in `gem' from /Users/simon/Library/Application Support/TextMate/Bundles/Ruby RSpec.tmbundle/Support/lib/spec_mate.rb:13 from /tmp/temp_textmate.oWRPUR:3:in `require' from /tmp/temp_textmate.oWRPUR:3 (I added linebreaks to make it readable) I'm using macports so my rspec gem is installed in /opt/local/lib/ruby/gems/1.8/gems/.

• How to handle CSS relative paths in an ASP.NET MVC application.

  - by AngryHacker

  I have a master page, which has a style sheet, which has the following line: .idle { background-image: url( '../../Images/blue_bg.png' ); } All my pages inherit from this master page. And this works well when the URL is http://www.domain.com/home/details/5, however the URL is http://www.domain.com/home/create, then, of course, blue_bg.png cannot be found because `../../Images/blue_bg.png' resolves to a directory one higher where there is nothing there. I tried the trick suggested by @codemeit in a similar question, but I can't plop down C# in a style sheet, can I? How is this typically handled?

• How do I free SQLServerCE's COM instance from the current running process?

  - by David Thornley

  It's been a while since I touched COM so be nice ;) This is under WindowsCE 5.0 with SQLServerCE 2.0. After calling this to load SQLServerCE 2.0 : - IDBInitialize *pIDBInitialize = NULL; CoCreateInstance(CLSID_SQLSERVERCE_2_0, NULL, CLSCTX_INPROC_SERVER, IID_IDBInitialize, (void**)&pIDBInitialize); Module load occurs for SSCE20.dll which obviously loads the SQLServerCE engine into the process space. What I don't understand is if I do this immediately after :- pIDBInitialize->Release(); I don't see a dll module unload, so that SSCE20.dll (and friends) are still loaded into my process. Now I tried CoFreeUnusedLibraries() which I figure forces COM to purge any unused libraries, but it doesn't seem to do the trick. At runtime I want to be able to completely unload the SQLServerCE 2.0 dll from the process to streamline an upgrade to 3.5SP1. I suspect this has something to do with the shared dll model that Microsoft use under WindowsCE... but, I might be wrong :) Thanks in advance, David.

• WinForms databind to collection property (such as count)

  - by Ornus

  I want to databind to a collection property, such as Count. in general, when I data bind I specify data member for the object property in the collection, not for the actual properties collection itself exposes. for example, I have a list of custom objects. I show them in datagridview. but I also want to show their total count using a separate label. is there a way to do this through databinding? I imagine that somehow I need to force PropertyManager to be used, instead of CurrentyManager? I get the following exception. Notice that DataSource is collection and has TotalValue property. System.ArgumentException: Cannot bind to the property or column TotalValue on the DataSource. Parameter name: dataMember at System.Windows.Forms.BindToObject.CheckBinding() at System.Windows.Forms.Binding.SetListManager(BindingManagerBase bindingManagerBase) at System.Windows.Forms.ListManagerBindingsCollection.AddCore(Binding dataBinding) at System.Windows.Forms.BindingsCollection.Add(Binding binding) at System.Windows.Forms.BindingContext.UpdateBinding(BindingContext newBindingContext, Binding binding) at System.Windows.Forms.Binding.SetBindableComponent(IBindableComponent value) at System.Windows.Forms.ControlBindingsCollection.AddCore(Binding dataBinding) at System.Windows.Forms.BindingsCollection.Add(Binding binding)

• How to use a scope in combination with a Model method?

  - by Bjorn

  Hi all, I'm currently working on some scope filters, and I'd like to have it filter on a method (don't know how to name it otherwise). My code: class Product < ActiveRecord::Base def price_with_discount price-discount.to_f end scope :by_price, lambda {|min,max|{ :conditions => { :price_with_discount => min.to_f..max.to_f }}} end This doesn't work: "No attribute named price_with_discount exists for table products". How can I trick my scope into using the method I defined instead of searching for a column named price_with_discount? Bjorn

• Implementing BindingList<T>

  - by EtherealMonkey

  I am trying to learn more about BindingList because I believe that it will help me with a project that I am working on. Currently, I have an object class (ScannedImage) that is a subtype of a class (HashedImage) that subtypes a native .Net object (Image). There is no reason why I couldn't move the two subtypes together. I am simply subtyping an object that I had previously constructed, but I will now be storing my ScannedImage object in an RDB (well, not technically - only the details and probably the thumbnail). Also, the object class has member types that are my own custom types (Keywords). I am using a custom datagridview to present these objects, but am handling all changes to the ScannedImage object with my own code. As you can probably imagine, I have quite a few events to handle that occur in these base types. So, if I changed my object to implement INotifyPropertyChanged, would the object collection (implementing BindingList) receive notifications of changes to the ScannedImage object? Also, if Keywords were to implement INotifyPropertyChanged, would changes be accessible to the BindingList through the ScannedImage object? Sorry if this seems rather newbish. I only recently discovered the BindingList and not having formal training in C# programming - am having a difficult time moving forward with this. Also, if anyone has any good reference material, I would be thankful for links. Obviously, I have perused the MSDN Library. I have found a few good links on the web, but it seems that a lot of people are now using WPF and ObservableCollection. My project is based on Winforms and .Net3.5 framework. TIA

• Date only from TextBoxFor()

  - by thekronos

  Hello, I'm having trouble displaying the only date part of a datetime into a textbox using TextBoxFor<,(expression, htmlAttributes). The model is based on Linq2SQL, field is a DateTime on SQL and in the Entity model. Failed : <%= Html.TextBoxFor(model => model.dtArrivalDate, String.Format("{0:dd/MM/yyyy}", Model.dtArrivalDate))%> Ps : this trick seems to be depreciated, any string value in the object htmlAttribute is ignored. Failed : [DisplayFormat( DataFormatString= "{0:dd/MM/yyyy}" )] public string dtArrivalDate { get; set; } I would like to store and display the date part only on the details/edit view without the "00:00:00" part. Any idea please ? Merry Chrismas from France to all by the way ;-)

• Does ActiveRecord make Ruby on Rails code hard to test?

  - by Erik Öjebo

  I've spent most of my time in statically typed languages (primarily C#). I have some bad experiences with the Active Record pattern and unit testing, because of the static methods and the mix of entities and data access code. Since the Ruby community probably is the most test driven of the communities out there, and the Rails ActiveRecord seems popular, there must be some way of combining TDD and ActiveRecord based code in Ruby on Rails. I would guess that the problem goes away in dynamic languages, somehow, but I don't see how. So, what's the trick?

• having a test debug app and a released debug app side by side

  - by Tristan

  Yo! When I download my app from the iStore, the latest test version installed to my phone gets over written. Does anyone know how to have two versions of the same app side by side? On a test project, I edited the build settings so that "realease" and "debug" have different product names. This seemed to solve my problem, however when I try this same trick on my actual project, the two overwrite each other again. Does anyone have a recommendation? I don't mind how it's done. Thanks!

• SSRS2008: LocalReport export to HTML / fragment

  - by queen3

  I need local RDL report to be exported to HTML, preferably HTML fragment. In 2005 it wasn't officially supported but there was a trick. In SSRS2008 they seem to drop this support (there's no HTML extension in the supported extensions when enumerating using reflection) and use RPL instead which is a binary format that I doubt someone will be happy to parse. Actually it's doesn't seem to be about HTML at all. Now, is there a way to render HTML using SSRS2008 local report? Notice that I use VS2008 but with reporting assemblies installed from VS2010 Beta 2 reportviewer.
