• Sorting a list of variable length integers delimited by decimal points...

  - by brewerdc

  Hey guys, I'm in need of some help. I have a list of delimited integer values that I need to sort. An example: Typical (alpha?) sort: 1.1.32.22 11.2.4 2.1.3.4 2.11.23.1.2 2.3.7 3.12.3.5 Correct (numerical) sort: 1.1.32.22 2.1.3.4 2.3.7 2.11.23.1.2 3.12.3.5 11.2.4 I'm having trouble figuring out how to setup the algorithm to do such a sort with n number of decimal delimiters and m number of integer fields. Any ideas? This has to have been done before. Let me know if you need more information. Thanks a bunch! -Daniel

• How do I obtain the version information for my Windows Service programmatically

  - by user302004

  I need to obtain the version of my Windows service programmatically and store it in a string. Then, I'll append the version to my display name and service name in the ProjectInstaller class. Right now I'm getting an empty string and I'm having trouble debugging my setup project. Here's my current code: string version = null; try { Assembly exeAssembly = Assembly.GetEntryAssembly(); Type attrType = typeof(AssemblyFileVersionAttribute); object[] attributes = exeAssembly.GetCustomAttributes(attrType, false); if (attributes.Length 0) { AssemblyFileVersionAttribute verAttr = (AssemblyFileVersionAttribute)attributes[0]; if (verAttr != null) { version = verAttr.Version; } } } catch { } if (version == null) { version = string.empty; }

• For-Each and Pointers in Java

  - by John

  Ok, so I'm tyring to iterate through an ArrayList and remove a specefic element. However, I am having some trouble using the For-Each like structure. When I run the following code: ArrayList<String> arr = new ArrayList<String>(); //... fill with some values (doesn't really matter) for(String t : arr) { t = " some other value "; //hoping this would change the actual array } for(String t : arr) { System.out.println(t); //however, I still get the same array here } My question in, how can I make 't' a pointer to 'arr' so that I am able to change the values in a for-each loop? I know I could loop through the ArrayList using a different structure, but this one looks so clean and readable, it would just be nice to be able to make 't' a pointer. All comments are appreciated! Even if you say I should just suck it up and use a different construct.

• Coping with weak typing

  - by John Leonard

  I'm a front end Flex developer peeking over the wall at html. One of the things I have a hard time with is weak typing in Javascript. I know many developers say they prefer it. How do I stop worrying and learn to love the weak typing? Are there best practices for variable naming that help make var types human readable? Another thing I have trouble with is getting by without my trusted compiler errors and warnings. I'm getting along with firebug. Is there anything else I should have in my toolkit?

• Can't connect to MySQL database hosted in CloudBees

  - by user3692698

  I have a free CloudBees account and created a free ClearDB database using their wizards. My trouble is when I use their connection information (whether I try to connect from my Java app, or an outside tool - SQLyog to be exact) I take the error: Access denied for user 'b51dbc5757d79f'@'%' to database 'mywiki. The username provided by CloudBees does not contain those extra characters that the error message is displaying which seems like it would be a problem, but I'm not sure there is anything I can do about that since everything is configured for me. The username I am given is: b51dbc5757d79f - which I can delete and rebuild after sharing here :)

• Samsung Galaxy Tab 1 layout problems

  - by William Rae

  I'm having trouble running my app on the Galaxy tab original 7". It appears to make everything 1.5 times bigger, i.e. if I specify 40dip for a textSize in my layout, it will display as 60 dip when I run it on the tablet. I tried messing around with the display metrics and changing the density and densityDpi to 1. (When I run a toString of the display metrics in the Galaxy tab 2, they are both 1, whereas the Galaxy tab 1 has values of 1.5) The app runs very well on every phone I've tested it on, and on the Galaxy tab 2, so I can't figure out what the problem is. I even tried creating a dummy app with just a textView with a size of 40dip, and it still converted it to 60. Any ideas? Thanks.

• How to check wether a path represented by a QString with german umlauts exists?

  - by MB

  Hey, i get a QString which represents a directory from a QLineEdit. Now i want to check wether a certain file exists in this directory. But if i try this with os.path.exists and os.path.join and get in trouble when german umlauts occur in the directory path: #the direcory coming from the user input in the QLineEdit #i take this QString to the local 8-Bit encoding and then make #a string from it target_dir = str(lineEdit.text().toLocal8Bit()) #the file name that should be checked for file_name = 'some-name.txt' #this fails with a UnicodeDecodeError when a umlaut occurs in target_dir os.path.exists(os.path.join(target_dir, file_name)) How would you check if the file exists, when you might encounter german umlauts?

• Help with setting up panels in Java

  - by Milos

  I'm new to Java awt, so I am having trouble with setting up panels. I have one giant panel, which needs to hold 3 panels inside (photo is attached at the bottom). One will go on top(1), second one will be in the middle(3), and third goes on the bottom(2). Any remaining space has to be divided equally between (1)/(3) and (3)/(2). Also, the middle panel (3) is a table, so GridLayout has to be used. How can I achieve this? Thanks in advance! P.S. I've tried to draw it in MS Paint (http://i45.tinypic.com/2w523ie.jpg)

• Setting a preferred item of a many-to-one in Django

  - by Mike DeSimone

  I'm trying to create a Django model that handles the following: An Item can have several Names. One of the Names for an Item is its primary Name, i.e. the Name displayed given an Item. (The model names were changed to protect the innocent.) The models.py I've got looks like: class Item(models.Model): primaryName = models.OneToOneField("Name", verbose_name="Primary Name", related_name="_unused") def __unicode__(self): return self.primaryName.name class Name(models.Model): item = models.ForeignKey(Item) name = models.CharField(max_length=32, unique=True) def __unicode__(self): return self.name class Meta: ordering = [ 'name' ] The admin.py looks like: class NameInline(admin.TabularInline): model = Name class ItemAdmin(admin.ModelAdmin): inlines = [ NameInline ] admin.site.register(Item, ItemAdmin) It looks like the database schema is working fine, but I'm having trouble with the admin, so I'm not sure of anything at this point. My main questions are: How do I explain to the admin that primaryName needs to be one of the Names of the item being edited? Is there a way to automatically set primaryName to the first Name found, if primaryName is not set, since I'm using inline admin for the names?

• Guice expert question

  - by Roman

  Hi All I am wondering if someone would be such an expert in guice that he even would know how to implement that : I have an injection annotation (@ConfParam)with some parameters , like that : class TestClass { private final int intValue; @Inject public TestClass(@ConfParam(section = "test1", key = "1") int intValue{ this.intValue = intValue; } public int getIntValue() { return intValue; } } The ConfParam is my custom annotation. Now , when the injection value is requested , I would like guice to create a dynamic binding, to resolve the value. For that binding I will need the parameters inside the annotation. Some example could be , I will have to look in the database in some table where the section is ? and the key is ?. All the trouble is that the data is not available when the injector is created and could be also be added at runtime. Ps. I static solution is easy. ( just have a look at the Names class)

• How do I make lambda functions generic in Scala?

  - by Electric Coffee

  As most of you probably know you can define functions in 2 ways in scala, there's the 'def' method and the lambda method... making the 'def' kind generic is fairly straight forward def someFunc[T](a: T) { // insert body here what I'm having trouble with here is how to make the following generic: val someFunc = (a: Int) => // insert body here of course right now a is an integer, but what would I need to do to make it generic? val someFunc[T] = (a: T) => doesn't work, neither does val someFunc = [T](a: T) => Is it even possible to make them generic, or should I just stick to the 'def' variant?

• Excel Worksheet Index

  - by Ben

  I have the following code that works great but I am trying to modify it so that instead of replacing column 1 of the Index page with a new index I would rather start the range in Cell C11. Right now, the new Index starts in Cell A1 of the Index sheet. Here is the code: Private Sub Worksheet_Activate() Dim wSheet As Worksheet Dim l As Long l = 1 With Me .Columns(1).ClearContents .Cells(1, 1) = "INDEX" .Cells(1, 1).Name = "Index" End With For Each wSheet In Worksheets If wSheet.Name <> Me.Name Then l = l + 1 With wSheet .Range("A1").Name = "Start_" & wSheet.Index .Hyperlinks.Add Anchor:=.Range("A1"), Address:="", _ SubAddress:="Index", TextToDisplay:="Back to Index" End With Me.Hyperlinks.Add Anchor:=Me.Cells(l, 1), Address:="", _ SubAddress:="Start_" & wSheet.Index, TextToDisplay:=wSheet.Name End If Next wSheet End Sub I have successfully modified the code so that the link back to the index on each sheet is in cell A4 without trouble, but I can't figure out how to have the index be replaced starting at Cell C11

• sed replacement does not work

  - by Robin Hood

  Hello, I have trouble using sed. I need to replace some lines in very deprecated HTML sites which consist of many files. My script does not work and I do not why. When I tried to find exact pattern with Netbeas it worked. find . -type f -name "*.htm?" -exec sed -i -r 's/ing\. Šuhajda Dušan\, Mírová 767\, 518 01 Dobruška\, \+420 737 980 333\,/REPLACEMENT/g' {} \; Where is the mistake? Is there an alternative to replace text without searching regular expression but plain text? Thanks for any respond.

• Loading and removing images with DOM, Javascript

  - by jesse

  I'm new to DOM and I'm having trouble removing multiple images that I loaded this loads 7 images (1.jpg, 2.jpg, etc..) function loadImages() { for (var i = 1; i < 8; i++ ) { var img = document.createElement("img"); img.src = "images/"+i+".jpg"; var idName = "img"+i+""; document.getElementById(idName).appendChild(img); } } this should remove all of them, but doesn't.. I think it breaks at the removeChild line. function removeImages() { for (var i = 1; i < 8; i++ ) { var idName = "img"+i+""; var d = document.getElementById(idName); d.removeChild(document.getElementById(img)); } } I think I'm doing something fundamentally wrong, because I don't fully understand how this works...

• How easy would it be to refactor a small JSP/Servlet/JDBC project to SpringMVC/Hibernate

  - by John

  With reference to this post, I am considering starting a new web-based Java project. Since I don't know Spring/Hibernate I was concerned if it's a bad plan to start learning them while creating a new project, especially since it will slow down the early development. One idea I had was to write a prototype using tech I do know, namely JSP/Servlets/JDBC, since I can get this running much quicker with my current knowledge. I could then throw the whole thing away and start over with Spring, etc, but I'd like to consider how easy it would be to refactor a smallish project from JSP/Servlets/JDB to SpringMVC/Hibernate? My DB could of course be re-used but what about other code... would I expect to save most of it plugged into an MVC framework, or is the paradigm shift big enough this would cause more trouble than it avoids? Please use the other question for more general advice on choosing technologies

• Handling Messages in Console Apps/DLLs in C++ Win32

  - by vsimon

  I would like to have the ability to process Win32 messages in a console app and/or inside a standalone DLL. I have been able to do it in .NET with the following article and it works great in C# inside a console app and standalone DLL http://msdn.microsoft.com/en-us/magazine/cc163417.aspx Is there a way to do the equivalent with C/C++ Win32 APIs? I have tried doing RegisterClassEx(...) and CreateWindow(...) even passing in HWND_MESSAGE to hWndParent but the trouble is that after the "invisible" window is created messages are not being processed probably due to the lack of a message pump. Where would the message pump go if you had a DLL entry point? I have tried creating another thread in a DLL and put while(GetMesage(..)) there but that did not work either. Any ideas?

• UIImageView is clipping a pixel of the bottom of my UIImage...?

  - by akaii

  I'm not sure what might be causing this, but UIImageView occasionally clips off about a pixel or 2 from the bottom of some square/rectangular UIImages I'm using as subviews for UITableViewCells. These UIImageViews are well within the borders of the cell, so it shouldn't be due to cliptobounds. There seems to be no consistency or pattern to which images are being clipped, nor when they're clipped, other than that it only happens to (or is only noticable in) square/rectangular icons, and only ones that are parented to UITableViewCells (or their subclasses). I'm having trouble reproducing the problem consistently, which is why I haven't posted any code this time. Has anyone encountered something similar to this before? I've encountered a similar bug that involved floating point values for origin/size being interpreted weirdly... but that doesn't seem to be the cause of this particular problem. I don't need a specific solution at this point, I'm just making sure I haven't missed any well-known bugs or documented problems that involve UIImageView.

• How Can I Join Two DB Tables and Return Lowest Price From Joined Table

• iPhone SDK 3.0 deprecation of UITableViewCell .text

  - by djt9000

  Came across an SDK3.0 deprecation that I am having a bit of trouble tryinig to figure out. If my declaration of @property (nonatomic, retain) UIImage *rowImage; does not work, nor @property (nonatomic, readonly, retain) UIImage *rowImage; and I @synthesize rowImage; Do I need to write my own setter because @synthesize will not properly handle this? cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:RootViewControllerCell] autorelease]; // Dpericated in SDK 3.0 // //cell.text = controller.title; //cell.image = controller.rowImage; // Using what the documentation says to use Error=== cell.textLabel = controller.title; Error=== cell.imageView = controller.rowImage; Error: Object cannot be set - Either readonly property or no setter found. Hope this makes sense, any help would be appreciated.

• SQL Server (2008) Creating link tables with unique rows

  - by peteski22

  Hi guys, I'm having trouble getting in touch with SQL Server Managemen Studio 2008! I want to create a link-table that will link an Event to many Audiences (EventAudience). An example of the data that could be contained: EventId | AudienceId 4 1 5 1 4 2 However, I don't want this: EventId | AudienceId 4 1 4 1 I've been looking at relationships and constraints.. but no joy so far! As a sneaky second part to the question, I would like to set up the Audience table such that if a row is deleted from Audience, it will clear down the EventAudience link table in a cascading manner. As always, ANY help/advice appreciated! Thanks Pete

• How do I override a Spring bean definition yet still reference the overriden bean?

  - by Kevin

  I'm attempting to implement a delegate Service provider by overriding the bean definition for the original service with my delegate Service. However, as the name would imply, the delegate Service needs a reference to the original service to delegate calls to. I'm having trouble figuring out how to override the bean definition while using the original bean def without running into a circular reference issue. For example: <!-- Original service def in spring-context.xml --> <bean id="service" class="com.mycompany.Service"/> <!-- Overridden definition in spring-plugin-context.xml --> <bean id="service" class="com.mycompany.DelegatedService"/> <constructor-arg ref="service"/> </bean> Is this possible?

• NSInvocation: object does not implement methodSignatureForSelector

  - by Sam V

  I have this weird crash that only happens when running the app on the device (doesn't happen in the Simulator). It seems like the problem surfaces out of nowhere, as I haven't changed anything on that particular class. I had the very same issue a few days ago, and I ended up fixing it by duplicating the class, renaming it, and changing the referenced class — I haven't changed a single bit of code. So I'm trying to understand why it's doing this. I've read somewhere that usually you get this console error when the object isn't a subclass of NSObject (but it is!). Here's the exact console error message: *** NSInvocation: warning: object 0x679e0 of class 'FFProximityPickerView' does not implement methodSignatureForSelector: -- trouble ahead *** NSInvocation: warning: object 0x679e0 of class 'FFProximityPickerView' does not implement doesNotRecognizeSelector: -- abort And then it crashes. I'd be very thankful for anyone who can help me on this.

• Allowing AsyncTask to Manipulate Values in Different Activity Classes

  - by Matt

  Hi guys, This title may seem strange, so let me try to explain what I'm trying to do. I have several activity classes, each representing a different view in my application. My initial activity class gets loaded when the application launches. The user enters values and eventually a TCP socket is opened, and I then use AsyncTask to listen for and respond to messages from the server. I'd like for this AsyncTask class to essentially listen until the app is closed/error condition reached, and be able to update values in other activity classes after they are started. Does this make sense (it's been a long, frustrating night)? I know that static activity class references are bad practice, and touching the UI thread from other activities is bad as well, but I'm having trouble finding a clean solution to this problem. Maybe using AsyncTask is not the best approach here? Should I be using a service instead or something else entirely? Thanks in advance.

• JQuery - which form was submitted?

  - by OneMostFrustratedChap

  Hello, I have a page of products and for each of them, I want to have a form that uses AJAX to update the session. I've done this bit - just providing background. I use the product's ID to create a different form class and name for each form, so each form is called something like this_form_name_567 and the next would be this_form_name_568 and so on. There is a submit button per form. I'm having trouble figuring out a) which event is best to use so that the correct form will be identified when a submit button is clicked, b) once clicked, how to then make sure the correct value is taken from a hidden field (unique ID) within the submitted form so that I can populate a line of code such as: $.post("compare_response.php", {compare_this: $("#compare_this").val()}, function(data){ } Any help would be greatly appreciated. Thank you
