• regex return conditional group

  - by priyank.mp

  Hi , I spent lot time figuring out a simple regex to return a group (only 1st group). So the string can be - "No purchase required" or "Purchase of $50.00 worth groceries is required." I am trying to write a regex which can parse "No" or "50" based on the given string. This is what I have written. (?:(No) monthly maintenance|Purchase of \$([\d\.]+ worth groceries) This works fine but I want my output as 1st group/group 1 only.

• Generated SQL with PredicateBuilder, LINQPad and operator ANY

  - by Sig. Tolleranza

  I previously asked a question about chaining conditions in Linq To Entities. Now I use LinqKit and everything works fine. I want to see the generated SQL and after reading this answer, I use LinqPad. This is my statement: var predProduct = PredicateBuilder.True<Product>(); var predColorLanguage = PredicateBuilder.True<ColorLanguage>(); predProduct = predProduct.And(p => p.IsComplete); predColorLanguage = predColorLanguage.And(c => c.IdColorEntity.Products.AsQueryable().Any(expr)); ColorLanguages.Where(predColorLanguage).Dump(); The code works in VS2008, compile and produce the correct result set, but in LinqPad, I've the following error: NotSupportedException: The overload query operator 'Any' used is not Supported. How can I see the generated SQL if LINQPad fails?

• Conditional includes in Classic ASP - where the file may not exist on the server

  - by Brent

  I am currently in a situation where I have to make some additions to an application written in classic ASP using server-side JScript on IIS. The additions that I need to make involve adding a series of includes to the server-side code to extend the application's capabilities. However, the inc files may not exist on the server in all cases, so I need the application to fall back to the existing behavior (ignore the includes) if the files do not exist, rather than generating an error. I know that this can't be accomplished using if statements in the JScript code because of the way that SSI works, and have not come across any ways of dynamically including the code on the server side, where the files may not exist. Does anyone know of a way to accomplish this in classic ASP? Any help would be much appreciated.

• Extract information from conditional formula

  - by Ken Williams

  I'd like to write an R function that accepts a formula as its first argument, similar to lm() or glm() and friends. In this case, it's a function that takes a data frame and writes out a file in SVMLight format, which has this general form: <line> .=. <target> <feature>:<value> <feature>:<value> ... <feature>:<value> # <info> <target> .=. +1 | -1 | 0 | <float> <feature> .=. <integer> | "qid" <value> .=. <float> <info> .=. <string> for example, the following data frame: result qid f1 f2 f3 f4 f5 f6 f7 f8 1 -1 1 0.0000 0.1253 0.0000 0.1017 0.00 0.0000 0.0000 0.9999 2 -1 1 0.0098 0.0000 0.0000 0.0000 0.00 0.0316 0.0000 0.3661 3 1 1 0.0000 0.0000 0.1941 0.0000 0.00 0.0000 0.0509 0.0000 4 -1 2 0.0000 0.2863 0.0948 0.0000 0.34 0.0000 0.7428 0.0608 5 1 2 0.0000 0.0000 0.0000 0.4347 0.00 0.0000 0.9539 0.0000 6 1 2 0.0000 0.7282 0.9087 0.0000 0.00 0.0000 0.0000 0.0355 would be represented as follows: -1 qid:1 2:0.1253 4:0.1017 8:0.9999 -1 qid:1 1:0.0098 6:0.0316 8:0.3661 1 qid:1 3:0.1941 7:0.0509 -1 qid:2 2:0.2863 3:0.0948 5:0.3400 7:0.7428 8:0.0608 1 qid:2 4:0.4347 7:0.9539 1 qid:2 2:0.7282 3:0.9087 8:0.0355 The function I'd like to write would be called something like this: write.svmlight(result ~ f1+f2+f3+f4+f5+f6+f7+f8 | qid, data=mydata, file="out.txt") Or even write.svmlight(result ~ . | qid, data=mydata, file="out.txt") But I can't figure out how to use model.matrix() and/or model.frame() to know what columns it's supposed to write. Are these the right things to be looking at? Any help much appreciated!

• Conditional OrderBy

  - by jeriley

  So, right now I've got a number of columns the user can sort by (Name, County, Active) and that's easy but messy. Looks something like this... Select Case e.SortExpression Case "Name" If (isDescending) Then resultsList.OrderByDescending(Function(a) a.Name).ToList() Else resultsList.OrderBy(Function(a) a.Name).ToList() End If Case "County" ... and so on what I would LIKE to do, is something more ... graceful, like this Private Function SortThatList(ByVal listOfStuff As List(Of Stuff), ByVal isDescending As Boolean, ByVal expression As Func(Of Stuff)) As List(Of Stuff) If (isDescending) Then Return listOfStuff.OrderByDescending(expression) Else : Return listOfStuff.OrderBy(expression) End If End Function but it doesn't like the datatype (Of TKey) ... I've tired Func(Of stuff, boolean) (got something in c# that works nicely like that) but can't seem to get this one to do what I want. Ideas? What's the magic syntax?

• (fluent) nhibernate conditional table mapping strategy

  - by grenade

  I have no control over database schema and have the following (simplified) table structure: CityProfile Id Name CountryProfile Id Name RegionProfile Id Name I have a .Net enum and class encapsulating the lot: public enum Scope { Region, Country, City } public class Profile { public Scope Scope { get; set; } public int Id { get; set; } public string Name { get; set; } } I am looking for a mechanism that allows me to map to the correct table, something like: public class ProfileMap : ClassMap<Profile> { public ProfileMap() { switch (x => x.Scope) { // <--Invalid code here! case Scope.City: Table("CityProfile"); break; case Scope.Country: Table("CountryProfile"); break; case Scope.Region: Table("RegionProfile"); break; } Id(x => x.Id); Map(x => x.Name); } } Or have I approached this wrong?

• Dynamic find methods Vs conditional statements

  - by piemesons

  Student.find(:all, :conditions => [‘name = ? and status = ?’ ‘mohit’, 1]) Vs Student.find_all_by_name_and_status(‘mohit’, 1) Both the queries will result the same set of row but first one is preferable cause in the second way there will be exception generated method_missing and then rails will try to relate it as dynamic method. if fine then result set to returned. Can any body explain me this in a good manner. What exactly is happening behind the screen. Please correct me if i am wrong.

• Conditional restart on Activity onConfigurationChanged

  - by yuku

  I want to make an activity that allows orientation changes on some condition, but not otherwise. More exactly I want to prevent restarting the activity when a background thread is busy. I have put the configChanges attribute on the activity manifest, and onConfigurationChanged is called when the orientation changes. However I want to allow the app to change the orientation when allowed. @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); if (orientationChangeAllowed) { // how to I restart this activity? } else { // don't do anything } }

• operator not defined for System.Data.SqlClient.SqlConnection and System.Data.SqlClient.SqlConnection

  - by Beta033

  i hope i'm just doing something wrong here. Ideally i'm trying to open the connection, open a transaction execute a ton of prebuilt sqlstatements (with parameters) against this connection then close the connection. ideally all in the same batch. It's easy enough to wrap this all in a for loop, however i'd like to use the forEach function of the list generic to set the connection as it'll probably be faster than my implementation of calling List.Item(i) in the loop but i get some strange errors. Dim sqlStatements As List(Of SqlCommand) = New List(Of SqlCommand) Dim conn As SqlClient.SqlConnection = New SqlConnection("...") sqlStatements.Item(0).Connection = conn 'Works sqlStatements.ForEach(Function(ByRef cmd As SqlCommand) cmd.Connection = conn) 'ERROR: Operator '=' is not defined for types 'System.Data.SqlClient.SqlConnection' 'and 'System.Data.SqlClient.SqlConnection What does this error really mean?

• Mixing regular expression and other conditional expression in a bash if statement

  - by Tassos

  I can't get around this for quite sometime now. As I read along manuals and tutorials I'm getting more confused. I want an if statement with the following logic: if [ -n $drupal_version ] && [[ "$drupal_version" =~ DRUPAL-[6-9]-[1-9][1-9] ]]; then but I can't get it to work properly. When the script is evaluated using the "bash -x ... " script construct, works ok but when is run as a regular script my expression is not evaluated (eventhough the above condition should be met the else part is run). Could you provide any help?

• maven conditional dependencies

  - by Joshua

  We would like to bundle library dependencies from (Alfresco or Jackrabbit or ...) based on the customer choice. The number of dependencies actually varies based on the chosen vendor. How do we provide hooks at the maven level, so that the final product just includes the dependent jars as per customer selection.

• Conditional Drag and Drop Operations in Flex/AS3 Tree

  - by user163757

  Good day everyone. I am currently working with a hierarchical tree structure in AS3/Flex, and want to enable drag and drop capabilities under certain conditions: Only parent/top level nodes can be moved Parent/top level nodes must remain at this level; they can not be moved to child nodes of other parent nodes Using the dragEnter event of the tree, I am able to handle condition 1 easily. private function onDragEnter(event:DragEvent):void { // only parent nodes (map layers) are moveable event.preventDefault(); if(toc.selectedItem.hasOwnProperty("layer")) DragManager.acceptDragDrop(event.target as UIComponent); else DragManager.showFeedback(DragManager.NONE); } Handling the second condition is proving to be a bit more difficult. I am pretty sure the dragOver event is the place for logic. I have been experimenting with calculateDropIndex, but that always gives me the index of the parent node, which doesn't help check if the potential drop location is acceptable or not. Below is some pseudo code of what I am looking to accomplish. private function onDragOver(e:DragEvent):void { // if potential drop location has parents // dont allow drop // else // allow drop } Can anyone provide advice how to implement this?

• Conditional Validation with Paperclip difficult

  - by Michael Schmitz

  Hi, I have an "item", which goes through a multi-page creation process. Images are uploaded at step five, and I keep track of the steps by using the attribute "complete". When validating whether an image is attached with paperclip, I get problems using the code below: validates_attachment_presence :pic1, :if => Proc.new { |u| u.complete == "step5"} It seems that I can't access the "complete" attribute, as the active-record object seems to be the paperclip image. Is there a way for me to check at which point in the process I am and validate conditionally? Thanks, Michael

• Perl file test operator help

  - by Aaron Moodie

  This is a really basic issue, but I'm new to perl and cannot work out what the issue is. I'm just trying to isolate the files in a directory, but the -d operator keeps treating all the folder contents as files ... @contents is my array, and when I run this: foreach $item(@contents) { if (-d $item) { next; } print"$item is a file\n"; } I keep getting both folders and files. Alternatively, if I use -f, I get nothing. edit: this is the output - file01.txt is a file folder 01 is a file folder 02 is a file Screen shot 2010-04-18 at 1.26.17 PM.png is a file I'm running this on OSX

• iphone - compiler conditional on header

  - by Mike

  I have a project that generates applications for two targets. One of the targets has to include one additional delegate protocol that should not be present on the other one. So, I have created a macro on Xcode and declared the header like this: #ifdef TARGET_1 @interface myViewController : UIViewController <UIScrollViewDelegate, UIPopoverControllerDelegate> #endif #ifdef TARGET_2 @interface myViewController : UIViewController <UIScrollViewDelegate> #endif { .... bla bla.... } The problem is that Xcode is not liking this "double" declaration of @interface and is giving me all sort of problems. How to solve that? thanks for any help.

• wordpress conditional statements

  - by codedude

  I am using this code in wordpress to display different content when different pages are loaded. I have 5 pages on the site called Home, Bio, Work, Contact and Notes. The Notes page is being used as a blog. Here is the code I am using. <?php if (is_page('contact')) { ?> get in touch with me <?php } elseif (is_single()) { ?> a note from me <?php } elseif (is_page('notes')) { ?> the notes of me <?php } else { ?> the <?php the_title(); ?> of me <?php } ?> So if it the contact page, it displays "get in touch with me" and if it is a single blog post page it displays "a note from me". However this is where I have a problem. The next statement should display "the notes of me" when it is on the Notes page. However, this does not happen. Instead it shows the default content which is in the "else" statement. any idea on why this is happening?

• Conditional ESC, ideas?

  I often need to enter insert mode just to make changes on a specific line, and would like know if there is a way to enter insert mode in a way that when I am done editing on that line, hitting [Return] gets me back to normal mode. I am aware of the 'r' command for replacing a single character, I guess what I want is something like that but for a line.
