  • Coldfusion Web Service Response Problem

    - by Ivan Paloscia
    I have a problem with the Web Service I recently developed. The problem is about the Web Service response. More precisely sometimes the Web Service sends back the following response: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <ns1:GetConstants2Response soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="http://usermanagerwstest"> <GetConstants2Return xsi:type="ns2:CFComponentSkeleton" xmlns:ns2="http://rpc.xml.coldfusion"/> </ns1:GetConstants2Response> </soapenv:Body> </soapenv:Envelope> Instead the correct response (that sometimes shows up in an intermittent way) is reported below: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <ns1:GetConstants2Response soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="http://usermanagerwstest"> <GetConstants2Return xsi:type="ns1:Constants2"> <BooleanTypeFalse xsi:type="xsd:string">0</BooleanTypeFalse> <BooleanTypeTrue xsi:type="xsd:string">1</BooleanTypeTrue> <GenderFemale xsi:type="xsd:string">F</GenderFemale> <GenderMale xsi:type="xsd:string">M</GenderMale> <LanguageEnglish xsi:type="xsd:string">inglese</LanguageEnglish> <LanguageItalian xsi:type="xsd:string">italiano</LanguageItalian> </GetConstants2Return> </ns1:GetConstants2Response> </soapenv:Body> </soapenv:Envelope> Where does the CFCComponentSkeleton comes from? I thank everybody in advance.

  • set Image to Button

    - by Ivan
    Hello all, Could somebody help me a little bit with my issue below? When I call the myFunction, images which I want to set to buttons appear after 2 sec simultaneously, not one by one with delay of 0.5 sec. More info: generatedNumbers is array with four elements of NSNumber (4,1,3,2) buttons are set in UIView via IB and are tagged (1,2,3,4) -(IBAction) myFunction:(id) sender { int i, value; for (i = 0; i<[generatedNumbers count]; i++) { value = [[generatedNumbers objectAtIndex:i] intValue]; UIButton *button = (UIButton *)[self.view viewWithTag:i+1]; UIImage *img = [UIImage imageNamed:[NSString stringWithFormat:@"%d.png",value]]; [button setImage:img forState:UIControlStateNormal]; [img release]; usleep(500000); } }

  • Which method should I use ?

    - by Ivan
    I want to do this exercise but I don't know exactly which method should I use for an exercise like this and what data will I use to test the algorithm. The driving distance between Perth and Adelaide is 1996 miles. On the average, the fuel consumption of a 2.0 litre 4 cylinder car is 8 litres per 100 kilometres. The fuel tank capacity of such a car is 60 litres. Design and implement a JAVA program that prompts for the fuel consumption and fuel tank capacity of the aforementioned car. The program then displays the minimum number of times the car’s fuel tank has to be filled up to drive from Perth to Adelaide. Note that 62 miles is equal to 100 kilometres. What data will you use to test that your algorithm works correctly?

  • Do you know of a free .Net component for visual flow model graph design and editing?

    - by Ivan
    An app (C#4, WinForms, Entity Framework, SQL Server 2008) of mine maintains a graph of interconnected objects, each having some simple member fields and a set of many directed (in and out) one-to-one links to other objects. I'd like to offer a user an ability to view and edit this graph visually some way, creating and removing connections, modifying objects attributes values and introducing/dropping objects. I suppose there has to be a framework (at list a primitive kind of) for this as visual model design tools are pretty common to meet. Do you know one?

  • What to write in "Web location" field when starting an "New website" in Visual Studio 2010?

    - by Ivan
    I want a website to be deployed automatically to a local IIS (built in Windows XP Pro SP3), avoiding VisualStudio-built-in server if possible. I'd like development source files to be stored in a project folder outside wwwroot (I wouldn't mind built files to be copied to wwwroot each time I press F5). I don't store my projects inside default directories inside "My documents". What should I specify as in "Web location" when starting an "New website" in Visual Studio 2010? A deployment path in wwwroot, a folder where I'd like to save my project, or something else? I want the website to be a part of a complex solution in VS 2010, also icludinc a class libray project, a WinForms application project, a Windows Service project and a common Entitity Framework data model.

  • What's the right way to communicate between 2 or more .Net applications running on a same computer w

    - by Ivan
    If my applications run on a same computer or even on different computers in a same LAN and need intense and quick communication, it seems illogical for me to use text-encoded web services and HTTP. I could possibly use IP/TCP/UDP sockets and invent my own protocols, but believe there is a standard way for .Net applications to send/receive object instances (and, maybe, even sharing an object by reference?). Can you tell me what's that standard way? I am only interested in .Net Framework 4 applications and don't need to support legacy frameworks.

  • Drawing tree diagram in ASP.Net MVC

    - by Ivan Crojach Karacic
    I am creating an web application for my tae kwon do club. People are able to register online for a tournament. After the registration deadline the web application generates a dendrogram. Something like this: I am wondering now how to draw it. Because of the fact that there are my weight and age categories i have to draw them dynamicly for each group. What is the easiest way to draw this inside a MVC view?

  • Precision of cos(atan2(y,x)) versus using complex <double>, C++

    - by Ivan
    Hi all, I'm writing some coordinate transformations (more specifically the Joukoswky Transform, Wikipedia Joukowsky Transform), and I'm interested in performance, but of course precision. I'm trying to do the coordinate transformations in two ways: 1) Calculating the real and complex parts in separate, using double precision, as below: double r2 = chi.x*chi.x + chi.y*chi.y; //double sq = pow(r2,-0.5*n) + pow(r2,0.5*n); //slow!!! double sq = sqrt(r2); //way faster! double co = cos(atan2(chi.y,chi.x)); double si = sin(atan2(chi.y,chi.x)); Z.x = 0.5*(co*sq + co/sq); Z.y = 0.5*si*sq; where chi and Z are simple structures with double x and y as members. 2) Using complex : Z = 0.5 * (chi + (1.0 / chi)); Where Z and chi are complex . There interesting part is that indeed the case 1) is faster (about 20%), but the precision is bad, giving error in the third decimal number after the comma after the inverse transform, while the complex gives back the exact number. So, the problem is on the cos(atan2), sin(atan2)? But if it is, how the complex handles that? Thanks!

  • While submitting app to iOS App Store, "Unable to unzip application"

    - by Ivan Vucica
    I've successfully submitted "Product Name" to App Store. However, submitting "Product Name Lite", I keep getting the error "Unable to unzip application" in both Application Loader and built-in Xcode's uploader. Error persists even after eliminating spaces from the product name; in fact, I don't think there's whitespace anywhere in the app or the plist anymore. What might be causing this "highly descriptive" error? I'm using Xcode 3.2.5. Attempting to clean, build, and build&archive did not help.

  • Can I use a single DateTime field on the Entity Framework model side when the value is stored in a set of Int fields in the actual database?

    - by Ivan
    The actual table in the database has separate integer fields for storing year, month, day, hour and minute values (all in UTC) (seconds and milliseconds are irrelevant for my task and considered equal to zero). Needless to say it would be of great convenience to have just one field of DateTime type on the application side and hide all the conversion under the cover of the Entity Framework model code. Any directions on how to do that? I am not very experienced with Entity Framework yet.

  • SWT Filedialog Open into home folder

    - by Ivan
    I want to open a FileDialog window into the user home folder (i.e. /home/user or /Users/unsername) I read the user home folder, using System.getProperty: String homefolder = System.getProperty(user.home); And the variable containts the correct home folder. But when i set the filterpath in FileDialog, it opens (in linux) only the /home level not entering into the user home dir. This is the source code: FileDialog dialog = new FileDialog(shell); dialog.setText("Choose a certificate"); String platform = SWT.getPlatform(); String homefolder = System.getProperty("user.home"); dialog.setFilterPath(homefolder); Any idea? Here a screenshot:

    I'm trying to extract a page name and query string from a URL which should not contain .html Here is an example code in Java: public class TestRegex { public static void main(String[] args) { Pattern pattern = Pattern.compile("/test/(((?!\\.html).)+)\\?(.+)"); Matcher matcher = pattern.matcher("/test/page?param=value"); System.out.println(matcher.matches()); System.out.println(matcher.group(1)); System.out.println(matcher.group(2)); } } By running this code one can get the following output: true page e What's wrong with my regex so the second group contains the letter e instead of param=value?

  • Index, assignment and increment in one statement behaves differently in C++ and C#. Why?

    - by Ivan Zlatanov
    Why is this example of code behaving differently in c++ and C#. [C++ Example] int arr[2]; int index = 0; arr[index] = ++index; The result of which will be arr[1] = 1; [C# Example] int[] arr = new int[2]; int index = 0; arr[index] = ++index; The result of which will be arr[0] = 1; I find this very strange. Surely there must be some rationale for both languages to implement it differently? I wonder what would C++/CLI output?

  • Do you use enums in your data applications and how?

    - by Ivan
    My practice shows that a general enterprise application has a lot of entities which's nature corresponds to an elementary enumeration. For example We may have an Order entity which may have such fields as "OrderType", "OrderStatus", "Currency", etc. referencing corresponding Entities which are nothing more than just a textual name bound to a key to be referenced. Using enums would look very natural here. But entities have to be defined in application code at design-time, am I right? While in we need to be able to CRUD enum value variants at runtime and use enums in server-side SQL queries (like stored procedures and views). What are you practices and thoughts on this subject? I am particularly interested in C#4, linq and T-SQL.
