• 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?

• Java Regular Expressions

  - by david robers

  Hi All, Im struggling to understand the regex documentation. How would I find the strings that contain exactly one C in the following text: ABCCAMNL YOOBABCCA XNABCCA ZDXUABCCA TAQABCC ISABCCA REABCCA CABCAMONPT Edit: private void matchIt(String regex, ArrayList<String> d) { Pattern p = Pattern.compile("[\\w^C]"); Matcher m = p.matcher(regex); for (int i = 0; i < d.size(); i++) { p.matcher(d.get(i)); if(m.find()){ out.println(d.get(i)); } } } i have the above function and it only outputs: ABCCAMNL YOOBABCCA Why is that?

• Using Lambda Expressions trees with IEnumerable

  - by Loathian

  I've been trying to learn more about using Lamba expression trees and so I created a simple example. Here is the code, this works in LINQPad if pasted in as a C# program. void Main() { IEnumerable<User> list = GetUsers().Where(NameContains("a")); list.Dump("Users"); } // Methods public IEnumerable<User> GetUsers() { yield return new User{Name = "andrew"}; yield return new User{Name = "rob"}; yield return new User{Name = "chris"}; yield return new User{Name = "ryan"}; } public Expression<Func<User, bool>> NameContains(string namePart) { return u => u.Name.Contains(namePart); } // Classes public class User { public string Name { get; set; } } This results in the following error: The type arguments for method 'System.Linq.Enumerable.Where(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly. However if I just substitute the first line in main with this: IEnumerable<User> list = GetUsers().Where(u => u.Name.Contains("a")); It works fine. Can tell me what I'm doing wrong, please?

• JSF Conditional formatting for onmouseover and such attributes.

  - by Ben

  Hi, I'm trying to format a panelgrid according to a value in the backing bean. I'm currently trying this as the value of the onmouseover attribute: this.className=#{(actions.currentlySelectedActionButton == 0)?'actionButton actionButtonChosen':'actionButton'}; whereas the CSS looks like this: (the relevant parts): .actionButton { width: 100%; height: 20px; border: thin solid #000; cursor:default; } .actionButtonChosen { background-color: blue; } It's not working. Anyone spotting the error would help me greatly. Thanks!

• Named Function Expressions in IE, part 2

  - by Polshgiant

  I asked this question a while back and was happy with the accepted answer. I just now realized, however, that the following technique: var testaroo = 0; (function executeOnLoad() { if (testaroo++ < 5) { setTimeout(executeOnLoad, 25); return; } alert(testaroo); // alerts "6" })(); returns the result I expect. If T.J.Crowder's answer from my first question is correct, then shouldn't this technique not work?

• Regular expressions and the question mark

  - by James P.

  I'm having trouble finding a regular expression that matches the following String. Korben;http://feeds.feedburner.com/KorbensBlog-UpgradeYourMind?format=xml;1 One problem is escaping the question mark. Java's pattern matcher doesn't seem to accept \? as a valid escape sequence but it also fails to work with the tester at myregexp.com. Here's what I have so far: ([a-zA-Z0-9])+;http://([a-zA-Z0-9./-]+);[0-9]+ Any suggestions?

• null-coalescing operator or conditional operator

  - by rkrauter

  Which coding style do you prefer: object o = new object(); //string s1 = o ?? "Tom"; // Cannot implicitly convert type 'object' to 'string' CS0266 string s3 = Convert.ToString(o ?? "Tom"); string s2 = (o != null) ? o.ToString() : "Tom"; s2 or s3? Is it possible to make it shorter? s1 does not obviously work.

• Javascript Regular Expressions - Replace non-numeric characters

  - by user271619

  This works: var.replace(/[^0-9]+/g, ''); That simple snippet will replace anything that is not a number with nothing. But decimals are real too. So, I'm trying to figure out how to include a period. I'm sure it's really simple, but my tests aren't working.

• typesafe NotifyPropertyChanged using linq expressions

  - by bitbonk

  Form Build your own MVVM I have the following code that lets us have typesafe NotifyOfPropertyChange calls: public void NotifyOfPropertyChange<TProperty>(Expression<Func<TProperty>> property) { var lambda = (LambdaExpression)property; MemberExpression memberExpression; if (lambda.Body is UnaryExpression) { var unaryExpression = (UnaryExpression)lambda.Body; memberExpression = (MemberExpression)unaryExpression.Operand; } else memberExpression = (MemberExpression)lambda.Body; NotifyOfPropertyChange(memberExpression.Member.Name); } How does this approach compare to standard simple strings approach performancewise? Sometimes I have properties that change at a very high frequency. Am I safe to use this typesafe aproach? After some first tests it does seem to make a small difference. How much CPU an memory load does this approach potentially induce?

• Conditional configuration in maven pom.xml

  I'd like to ONLY exclude certain files in maven-war-plugin when property "skipCompress" set to true, I thought I could do something like this, but it doesn't work for me.

• matching files with regular expressions

  - by Javier

  Dear all, I have an input file with a list of movies (Note that there might be some repeated entries): American_beauty__1h56mn38s_ As_Good_As_It_Gets As_Good_As_It_Gets _DivX-ITA__Casablanca_M_CURTIZ_1942_Bogart-bergman_ Capote_EN_DVDRiP_XViD-GeT-AW _DivX-ITA__Casablanca_M_CURTIZ_1942_Bogart-bergman_ I would to find the corresponding match (line number) from another reference file for each of the entries in the first file: American beauty.(1h56mn38s) As Good As It Gets Capote.EN.DVDRiP.XViD-GeT-AW [DivX-ITA] Casablanca(M.CURTIZ 1942 Bogart-bergman) Quills (2000)(7.4) The desired output would be something like (Reference Movie + Line number from the Reference File): American beauty.(1h56mn38s) 1 As Good As It Gets 2 As Good As It Gets 2 [DivX-ITA] Casablanca(M.CURTIZ 1942 Bogart-bergman) 4 Capote.EN.DVDRiP.XViD-GeT-AW 3 [DivX-ITA] Casablanca(M.CURTIZ 1942 Bogart-bergman) 4 Basically, the difference between the entries in both files is that some characters such as: blank spaces, parenthesis, points, etc. have been replaced by underscores. Does anybody could shed some light on it? Best wishes, Javier

• .NET equivalent to Perl regular expressions

  - by r_honey

  I need to convert a Perl script to VB.NET. I have managed almost the entire conversion, but some Perl (seemingly simple) regex are causing an headache. Can someone suggest me .NET equivalent of the following perl regex: 1) $letter =~ s/Users //,; $letter =~ s/Mailboxes //,; if($letter =~ m/$first_char/i){ 2) unless($storegroup =~ /Recovery/ || $storegroup =~ /Users U V W X Y Z/ || $storegroup =~ /Users S T/ || $storegroup =~ /Users Q R/){ The regex look simple to me. I tried to wade through perl.org but understanding a langugae regex takes sometime and I need to complete the conversion quickly.

• 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?
