  • What's wrong with my logic (Java syntax)

    - by soda
    I'm trying to make a simple program that picks a random number and takes input from the user. The program should tell the user if the guess was hot (-/+ 5 units) or cold, but I never reach the else condition. Here's the section of code: public static void giveHint (int guess) { int min = guess - 5; int max = guess + 5; if ((guess > min) && (guess < max)) { System.out.println("Hot.."); } else { System.out.println("Cold.."); } }

  • Parse a string containing percent sign into decimal

    - by Sebastian Seifert
    I have a simple string containing VAT-percantage value that needs to be stored in a decimal. The string looks like this: "19.00%". When I use the decimal.Parse() methode I always get an FormatException. Code looks like this NumberFormatInfo nfi = new NumberFormatInfo() { PercentDecimalSeparator = ".", PercentSymbol = "%" }; decimal.Parse("19.00%",NumberStyles.Any, nfi); I know, that it would be possible (in the excample above) to simply remove the %-char from the string and then parse. But isn't there a solution to use built in parsing, which can be used without testing the string for the type of number the user typed in.

  • How should I embed/include Enterprise Architect UML diagrams in MS PowerPoint 2007?

    - by bn
    Setup I am using Sparx Systems Enterprise Architect Professional edition 7.5: http://www.sparxsystems.com.au/ and MS PowerPoint. Problem I have various audiences for presentations requiring display in MS PowerPoint -- ranging from managers to developers, whose depth of technical knowledge and requirements for knowledge varies. Question I have tried various settings for fonts, colors, and so on, but displaying a diagram with any level of detail (even simple class diagrams). These diagrams are very difficult to fit into a PowerPoint slide and render well when using a projector or a Live Meeting. Am I on the wrong path here, or is there a better/correct way to accomplish this? Thank you for the help, -bn

  • NSString stringWithContentsOfFile failing with what seems to be the wrong error code

    - by deanWombourne
    Hello. I'm trying to load a file into a string. Here is the code I'm using: NSError *error = nil; NSString *fullPath = [[NSBundle mainBundle] pathForResource:filename ofType:@"html"]; NSString *text = [NSString stringWithContentsOfFile:fullPath encoding:NSUTF8StringEncoding error:&error]; When passed in @"about" as the filename, it works absolutely fine, showing the code works. When passed in @"eula" as the filename, it fails with 'Cocoa error 258', which translates to NSFileReadInvalidFileNameError. However, if I swap the contents of the files over but keep the names the same, the other file fails proving there is nothing wrong with the filename, it's something to do with the content. The about file is fairly simple HTML but the eula file is a massive mess exported from Word by the legal department. Does anyone know of anything inside a HTML file that could cause this error to be raised? Much thanks, Sam

  • Consuming WCF from BizTalk 2006r1

    - by Rob Bowman
    Hi I need to create an Orchestration in BizTalk 2006r1 that will consume a WCF basicHTTP web service. Does anyone have a pointers on how to do this please? The WCF service has been created by another team but I am able to request that they create an additional endpoint with binding configuration set to make calling from BizTalk SOAP adapter possible. I just created a simple test basicHTTP service that runs fine when tested from a command line client. When I got to BizTalk add web reference I am able to browse to the service but then get a message "Failed to add web reference" and it bombs out! Any help gratefully received. Thanks Rob.

  • Horizontal placement of components in JSF.

    - by Ben
    Hi, Should be simple but I couldn't find the answer, I would like to place components horizontally instead of vertically. What I'm trying to achieve is a rich:toolbar with 2 or more rows. I've been trying to do that with a toolbar that has a panelgrid and two panelgroups like this: <rich:toolbar...> <f:panelgrid columns="1"...> <f:panelgroup id="row1" .../> <-- Should be horizontal placement <f:panelgroup id="row2" .../> <-- Should be horizontal placement <f:panelgrid/> <rich:toolbar/> So how do I make the panelgroup layout horizontal (Or should I use something else?) Thanks!

  • how to use expressons as function parameters in powershell

    - by rmeador
    This is a very simple task in every language I have ever used, but I can't seem to figure it out in PowerShell. An example of what I'm talking about in C: abs(x + y) The expression x + y is evaluated, and the result passed to abs as the parameter... how do I do that in PowerShell? The only way I have figured out so far is to create a temporary variable to store the result of the expression, and pass that. PowerShell seems to have very strange grammar and parsing rules that are constantly catching me by surprise, just like this situation. Does anyone know of documentation or a tutorial that explains the basic underlying theory of the language? I can't believe these are all special cases, there must be some rhyme or reason that no tutorial I have yet read explains. And yes, I've read this question, and all of those tutorials are awful. I've pretty much been relegated to learning from existing code.

  • Accessing the params hash for year and month rails and using in helper

    - by Matt
    So I took some php code and turned it into a calendar with a helper to make a simple calendar. I got my data from inside the helper: def calendar_maker a = Time.now b = a.month d = a.year h = Time.gm(d,b,1) #first day of month Now I want to try and do it with parameters within my method #from the helper file def calendar_maker(year, month) a = Time.now b = month c = year h = Time.gm(d,b,1) #first day of month #from my html.erb file <%= @month %> and <%= @year %> <%= params["month"] %><br /> <%= params["action"] %><br /> <%= params["year"] %><br /> <%= calendar_maker( @year, @month) %> #from controller file def calendar @month = params[:month] @year = params[:year] end Anyways mistakes were made and not finding documentation anywhere or not looking in the right place. How do I get this to work with my params hash. Thanks for the help.

  • Quick example of multi-column results with jQueryUI's new Autocomplete?

    - by Lance May
    I just found out that the jQueryUI now has it's own built-in auto-complete combo box. Great news! Unfortunately, the next thing I found is that making it multi-column doesn't seem nearly that simple (at least via documentation). There is a post here where someone mentions that they've done it (and even gives code), but I'm having trouble understanding what some of their code is doing. I'm just curious if anyone has ran across this before and could post a quick and easy sample of making a multi-column result set. Thanks much in advance.

  • How can I generate a list of words made up of combinations of three word lists in Perl?

    - by Chris Denman
    I have three lists of words. I would like to generate a single list of all the combinations of words from the three lists. List 1: red green blue List 2: one two List 3: apple banana The final list would like like so: red one apple red two apple red one banana red two banana ... and so on Ideally I'd like to pass in three arrays and the routine return one array. I have done a simple loop like so: foreach $word1 (@list1){ foreach $word2 (@list2){ foreach $word3 (@list3){ print "$word1 $word2 $word3\n"; } } } However, this doesn't work if there's nothing in the second or third list (I may only want to iterate between one, two or three lists at a time - in other words, if I only supply two lists it should iterate between those two lists).

  • Decoupling into DAL and BLL - my concerns.

    - by novice_man
    Hi, In many posts concerning this topic I come across very simple examples that do not answer my question. Let's say a have a document table and user table. In DAL written in ADO.NET i have a method to retries all documents for some criteria. Now I the UI I have a case where I need to show this list along with the names of the creator. Up to know I have it done with one method in DAL containig JOIN statement. However eveytime I have such a complex method i have to do custom mapping to some object that doesn't mark 1:1 to DB. Should it be put into another layer ? If so then I will have to resing from join query for iteration through results and querying each document author. . . which doen't make sense... (performance) what is the best approach for such scenarios ?

  • Zipping increment file names using Zip Utils

    - by Peter
    Hello I've been using "Zip Utils" from http://www.codeproject.com/Articles/7530/Zip-Utils-clean-elegant-simple-C-Win32 to zip files and folders. the easy thing is if the file name is known i just need to do something like this HZIP hz; DWORD writ; hz = CreateZip(_T("filename\\image1.zip"),0); The problem is I get errors when trying to zip files by incrementing file names within a loop int i= 0; for(i=0; i<record; i++) { ZipAdd(hz,_T("doc"+i+1+".kml"), _T("filename\\doc"+i+1+".kml")); }

  • How to null a translation in gettext system?

    - by Evgeny
    Suppose a simple phrase "In" in English needs to be interpreted as "" - empty string in Russian. Is is possible to specify that in the .po file? What normally happens if you set msgstr "" - you'll get the untranslated key, but I want to get nothing in that specific case. Here is a use case: I have underneath a giant search bar a set of buttons to select questions (for a Q&A site) from particular scopes - like so: (in English) In: [all] [unanswered] [my own] (in Russian I want) [???] [??? ???????] [???] It just sounds more natural. Yes I can leave out In for english, but I don't want to and I do not want to put button (things in [] are buttons) html into the 'po' file. Thanks!

  • Animating UIImageView iPhone

    - by Fred Dpn
    Hi, i'm having trouble about animating an Image in a UIImageView. I've created an image view in interface builder and linked it to its iboutlet. Here is my code. @interface Game : UIViewController <UIAccelerometerDelegate>{ IBOutlet UIImageView *diying; } @property (nonatomic, retain) UIImageView *diying; In the viewDidLoad method i've written this code NSArray * imageArray = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"Die1.gif"], [UIImage imageNamed:@"Die2.gif"], [UIImage imageNamed:@"Die3.gif"], [UIImage imageNamed:@"Die4.gif"], nil]; diying.animationImages = imageArray; diying.animationDuration = 1.1; diying.contentMode = UIViewContentModeBottomLeft; [diying startAnimating]; [super viewDidLoad]; which is a adaptation of what i've found here : http://icodeblog.com/2009/07/24/iphone-programming-tutorial-animating-a-game-sprite/ NB : those .gif files are simple images and are not animated. I did the tutorial and it worked fine but i can't figure out why it my adaptation doesn't work !

  • C# Event Handlers automatically created by WinForms Designer

    - by RHaguiuda
    Just moved from VB.NET to C#. In VB to connect and Event Handler to a Sub we use the Handles clause. From what it seems, this do not exist in C#. After creating a simple application with a button I realize that Window Forms Designer automatically created an EventHandler to my button1_Click function (after I double clicked it), in Form1.Designer.cs with this code: this.button1.Click += new System.EventHandler(this.button1_Click); But, in VB, the WinForms Designer create the Handles clause in my class, in the function header. So, C# create the default EventHandler in designer file, while VB creates in main class with control resides. Is this correct? Am I missing something here?

  • Need help creating flash animation with clickable buttons at the end.

    - by goldenfeelings
    Very inexperienced with Flash, but I hope this is simple enough for someone to walk me through. I'm ultimately trying to create a flash page for an html website that has a brief five-second animation during which 3 buttons fade in (buttons then become clickable after the animation is over). The animation part is done. Right now, I am trying to get my movie to stop and hold on the last frame, where I want to add the 3 buttons that the user can click on to take them to one 3 different html pages of my website. All instructions that I've found online have said to create a new layer for actions, insert a keyframe on the last frame of the movie, and add stop(); in the actionscript window. However, when I have the keyframe selected, my actionscript window says "current selection cannot have actions applied to it". Any ideas? I definitely don't have any objects selected, just the keyframe. Or, am I approaching this totally wrong?

  • Making an ANT Macro more reusable

    - by 1ndivisible
    I have a simple macro (simplified version below). At the moment it assumes that there will be a single value for a single argument, however there might be multiple values for that argument. How can I pass in 0+ values for that argument so that the macro is usable in situations where I need to pass in 0+ values for that argument, not just a single value <macrodef name="test"> <attribute name="target.dir" /> <attribute name="arg.value" /> <sequential> <java jar="${some.jar}" dir="@{target.dir}" fork="true" failonerror="true"> <arg value="-someargname=@{arg.value}"/> </java> </sequential> </macrodef>

    - by Mario
    Hello all, I have the following query that retrieve the number of users per country; SELECT C.CountryID AS CountryID, C.CountryName AS Country, Count(FirstName) AS Origin FROM Users AS U INNER JOIN Country AS C ON C.CountryID = U.CountryOfOrgin GROUP BY CASE C.CountryName, C.CountryID What I need is a way to get the top 10 and then sum all other users in a single row. I know how to get the top 10 but I`m stuck on getting the remaining in a single row. Is there a simple way to do it? For example if the above query returns 17 records the top ten are displayed and a sum of the users from the 7 remaining country should appear on row 11. On that row 11 the countryid would be 0 and countryname Others Thanks for your help!

  • Split string on non-alphanumerics in PHP? Is it possible with php's native function?

    - by Jehanzeb.Malik
    I was trying to split a string on non-alphanumeric characters or simple put I want to split words. The approach that immediately came to my mind is to use regular expressions. Example: $string = 'php_php-php php'; $splitArr = preg_split('/[^a-z0-9]/i', $string); But there are two problems that I see with this approach. It is not a native php function, and is totally dependent on the PCRE Library running on server. An equally important problem is that what if I have punctuation in a word Example: $string = 'U.S.A-men's-vote'; $splitArr = preg_split('/[^a-z0-9]/i', $string); Now this will spilt the string as [{U}{S}{A}{men}{s}{vote}] But I want it as [{U.S.A}{men's}{vote}] So my question is that: How can we split them according to words? Is there a possibility to do it with php native function or in some other way where we are not dependent? Regards

  • Getting closure-compiler and Node.js to play nice

    - by bukzor
    Are there any projects that used node.js and closure-compiler (CC for short) together? The official CC recommendation is to compile all code for an application together, but when I compile some simple node.js code which contains a require("./MyLib.js"), that line is put directly into the output, but it doesn't make any sense in that context. I see a few options: Code the entire application as a single file. This solves the problem by avoiding it, but is bad for maintenance. Assume that all files will be concatenated before execution. Again this avoids the problem, but makes it harder to implement a un-compiled debug mode. I'd like to get CC to "understand" the node.js require() function, but that probably can't be done without editing the compiler itself, can it?

  • How to refresh an activity?

    - by poeschlorn
    Hi Guys, after implementing some Android Apps, including several Map activities, I try to refresh the activity when the GPS listener's onLocationChanged() mehtod is called. I have no Idea how to tell the map activity to refresh on its own and display the new coords... the coords to store will have to be in global values, so that the location listener will have access to it. In my sample GPS-class (see code below) I just changed the text of a text view....but how to do that in map view? private class MyLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { final TextView tv = (TextView) findViewById(R.id.myTextView); if (loc != null) { tv.setText("Location changed : Lat: " + loc.getLatitude() + " Lng: " + loc.getLongitude()); } } I think the solution of this Problem won't be very difficult, but I just need the beginning ;-) This whole app shall work like a really simple navigation system. It would be great if someone could help me a little bit further :) nice greetings, Poeschlorn

  • Convert an XML object back into a string in ColdFusion

    - by jpmyob
    In ColdFusion, I can parse a string of XML formatted data into an XML Object using xmlParse(). How can I convert it back into a string? When I tried using toString() it throws an error that "it can't convert complex object to simple objects....", which is ironic because that's what it's supposed to do. I need to use XMLTransform() which requires the first argument to be an xml string. But I also need to use xmlSearch() to get a node to pass into my transform, and xmlSearch returns an xmlObject. So now I need to put that object back into xml string format to pass into xmlTransform.

  • Is recursion preferred compare to iteration in multicore era?

    - by prM
    Or say, do multicore CPUs process recursion faster than iteration? Or it simply depends on how one language runs on the machine? like c executes function calls with large cost, comparing to doing simple iterations. I had this question because one day I told one of my friend that recursion isn't any amazing magic that can speed up programs, and he told me that with multicore CPUs recursion can be faster than iteration. EDIT: If we consider the most recursion-loved situation (data structure, function call), is it even possible for recursion to be faster?

  • Regex for finding valid sphinx fields

    - by mlissner
    I'm trying to validate that the fields given to sphinx are valid, but I'm having difficulty. Imagine that valid fields are cat, mouse, dog, puppy. Valid searches would then be: @cat search terms @(cat) search terms @(cat, dog) search term @cat searchterm1 @dog searchterm2 @(cat, dog) searchterm1 @mouse searchterm2 So, I want to use a regular expression to find terms such as cat, dog, mouse in the above examples, and check them against a list of valid terms. Thus, a query such as: @(goat) Would produce an error because goat is not a valid term. I've gotten so that I can find simple queries such as @cat with this regex: (?:@)([^( ]*) But I can't figure out how to find the rest. I'm using python & django, for what that's worth.
