  • 'click' observer in Prototype

    - by Tom
    I have a page which contains several divs (each with a unique ID and the same class, 'parent'). Underneath each "parent" div, is a div with class "child" and unique ID name -child. This DIV is upon page load empty. Whenever you click on a parent DIV, the following code is executed. $$('div.parent').each(function(s){ $(s).observe('click', function(event){ event.stop(); var filer = $(s).readAttribute('filer'); var currentElement = $(s).id; var childElement = currentElement + '-children'; new Ajax.Updater ({success: childElement}, root + '/filers/interfacechildren', { parameters: {parentId: currentElement, filer: filer} }); }); }); Of course, it's possible that a child node is again a parent ont its own. The response looks like this (Smarty with Zend Framework): {foreach from=$ifaces item=interface} <div id="{$interface->name}" filer="{$interface->system_id}" class="parent">{$interface->name}</div> <div id="{$interface->name}-children" class="child"></div> {/foreach} Whenever I click on a "parent" div that is loaded inside a child, nothing happens :( Any suggestions / fixes how to fix this?

  • Remove appearance of TextField in droidText : Android

    - by AnujAroshA
    I am trying to create a PDF using droidText library. There I want to place some text content in the middle of the page but align to left. I was unable to do with Paragraph class and setAlignment() method. So I have decided to use TextField class. Below is the code I have used, Document document = new Document(PageSize.A4); try { PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(android.os.Environment.getExternalStorageDirectory() + java.io.File.separator + "TextFields.pdf")); document.open(); TextField tf = new TextField(writer, new Rectangle(100, 300, 200, 350), "Content"); tf.setText("This is the content of text field"); tf.setAlignment(Element.ALIGN_CENTER); tf.setOptions(TextField.MULTILINE | TextField.REQUIRED); PdfFormField field = tf.getTextField(); writer.addAnnotation(field); } catch (DocumentException de) { System.err.println(de.getMessage()); } catch (IOException ioe) { System.err.println(ioe.getMessage()); } document.close(); Code works perfect, but the out put PDF file that I am getting has this TextField which can be editable and also change the font appearance when I am click on the TextField. I don't want that in to my final PDF. How can I remove that attribute? If it is not possible, is there any other way I can position some text in a PDF file using droidText library in Android?

  • pagination for displaytag with colorbox in Spring framework

    - by Hitesh Solanki
    Hi..... I want to display the pop up for user selection using colorbox. I have put link on manageblacklist.jsp named 'select'. when I click on 'select' link ,colorbox is displayed. all user is displayed but pagination is not worked. I have used display tag for pagination. Without using colorbox, pagination is worked fine. I have used spring framework.

  • COM Object Clean Up

    - by Reggie McCray
    What is the difference between the two lines of code below: CComPtr< IInterface > m_interface; IInterface* m_interface; I know that CComPtr help eliminate memory leaks, but I am getting inconsistent results. When declaring the pointer with CComPtr< IInterface > m_interface; and using the interface in my C# code there are no errors, however using the Interface in VC++ I get an unhandled exception error, even if I comment out the instance creation of IInterface. I am pretty sure the problem is in here somewhere: STDMETHODIMP CSomeClass::get_IClass(IClass** var) { return m_class_var->QueryInterface(var); } STDMETHODIMP CSomeClass::putref_IClass(IClass* var) { m_class_var = var; return S_OK; } When I declare the interface pointer with: IInterface* m_interface; I get a RPC_E_SERVERFAULT error when testing the Interface in C# and have to explicitly call GC.Collect() to avoid the error being thrown after instantiation of a few objects. When testing the Interface in VC++ the error is consistent however when it occurs is different. If I comment out the instance creation of IInterface the code runs fine, however when I try to create an instance I get same error as before, just a vague unhandled exception error. What am I doing wrong here?

  • How to inject a Session Bean into a Message Driven Bean?

    - by Hank
    Hi guys, I'm reasonably new to JEE, so this might be stupid.. bear with me pls :D I would like to inject a stateless session bean into a message-driven bean. Basically, the MDB gets a JMS message, then uses a session bean to perform the work. The session bean holds the business logic. Here's my Session Bean: @Stateless public class TestBean implements TestBeanRemote { public void doSomething() { // business logic goes here } } The matching interface: @Remote public interface TestBeanRemote { public void doSomething(); } Here's my MDB: @MessageDriven(mappedName = "jms/mvs.TestController", activationConfig = { @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"), @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue") }) public class TestController implements MessageListener { @EJB private TestBean testBean; public TestController() { } public void onMessage(Message message) { testBean.doSomething(); } } So far, not rocket science, right? Unfortunately, when deploying this to glassfish v3, and sending a message to the appropriate JMS Queue, I get errors that glassfish is unable to locate the TestBean EJB: java.lang.IllegalStateException: Exception attempting to inject Remote ejb-ref name=mvs.test.TestController/testBean,Remote 3.x interface =mvs.test.TestBean,ejb-link=null,lookup=null,mappedName=,jndi-name=mvs.test.TestBean,refType=Session into class mvs.test.TestController Caused by: com.sun.enterprise.container.common.spi.util.InjectionException: Exception attempting to inject Remote ejb-ref name=mvs.test.TestController/testBean,Remote 3.x interface =mvs.test.TestBean,ejb-link=null,lookup=null,mappedName=,jndi-name=mvs.test.TestBean,refType=Session into class mvs.test.TestController Caused by: javax.naming.NamingException: Lookup failed for 'java:comp/env/mvs.test.TestController/testBean' in SerialContext [Root exception is javax.naming.NamingException: Exception resolving Ejb for 'Remote ejb-ref name=mvs.test.TestController/testBean,Remote 3.x interface =mvs.test.TestBean,ejb-link=null,lookup=null,mappedName=,jndi-name=mvs.test.TestBean,refType=Session' . Actual (possibly internal) Remote JNDI name used for lookup is 'mvs.test.TestBean#mvs.test.TestBean' [Root exception is javax.naming.NamingException: Lookup failed for 'mvs.test.TestBean#mvs.test.TestBean' in SerialContext [Root exception is javax.naming.NameNotFoundException: mvs.test.TestBean#mvs.test.TestBean not found]]] So my questions are: - is this the correct way of injecting a session bean into another bean (particularly a message driven bean)? - why is the naming lookup failing? Thanks for all your help! Cheers, Hank

  • Objective-C Pointer to class that implements a protocol

    - by Winder
    I have three classes which implement the same protocol, and have the same parent class which doesn't implement the protocol. Normally I would have the protocol as pure virtual functions in the parent class but I couldn't find an Objective-C way to do that. How can I utilize polymorphism on these subclasses and call the functions implemented in the protocol without warnings? Some pseudocode if that didn't make sense: @interface superclass: NSObject {} @interface child1: superclass<MyProtocol> {} @interface child2: superclass<MyProtocol> {} The consumer of these classes: @class child1 @class child2 @class superclass @interface SomeViewController: UIViewController { child1 *oneView; child2 *otherView; superclass *currentView; } -(void) someMethod { [currentView protocolFunction]; } The only nice way I've found to do pure virtual functions in Objective-C is a hack by putting [self doesNotRecognizeSelector:_cmd]; in the parent class, but it isn't ideal.

  • N-Tier Architecture - Structure with multiple projects in VB.NET

    - by focus.nz
    I would like some advice on the best approach to use in the following situation... I will have a Windows Application and a Web Application (presentation layers), these will both access a common business layer. The business layer will look at a configuration file to find the name of the dll (data layer) which it will create a reference to at runtime (is this the best approach?). The reason for creating the reference at runtime to the data access layer is because the application will interface with a different 3rd party accounting system depending on what the client is using. So I would have a separate data access layer to support each accounting system. These could be separate setup projects, each client would use one or the other, they wouldn't need to switch between the two. Projects: MyCompany.Common.dll - Contains interfaces, all other projects have a reference to this one. MyCompany.Windows.dll - Windows Forms Project, references MyCompany.Business.dll MyCompany.Web.dll - Website project, references MyCompany.Business.dll MyCompany.Busniess.dll - Business Layer, references MyCompany.Data.* (at runtime) MyCompany.Data.AccountingSys1.dll - Data layer for accounting system 1 MyCompany.Data.AccountingSys2.dll - Data layer for accounting system 2 The project MyCompany.Common.dll would contain all the interfaces, each other project would have a reference to this one. Public Interface ICompany ReadOnly Property Id() as Integer Property Name() as String Sub Save() End Interface Public Interface ICompanyFactory Function CreateCompany() as ICompany End Interface The project MyCompany.Data.AccountingSys1.dll and MyCompany.Data.AccountingSys2.dll would contain the classes like the following: Public Class Company Implements ICompany Protected _id As Integer Protected _name As String Public ReadOnly Property Id As Integer Implements MyCompany.Common.ICompany.Id Get Return _id End Get End Property Public Property Name As String Implements MyCompany.Common.ICompany.Name Get Return _name End Get Set(ByVal value as String) _name = value End Set End Property Public Sub Save() Implements MyCompany.Common.ICompany.Save Throw New NotImplementedException() End Sub End Class Public Class CompanyFactory Implements ICompanyFactory Public Function CreateCompany() As ICompany Implements MyCompany.Common.ICompanyFactory.CreateCompany Return New Company() End Function End Class The project MyCompany.Business.dll would provide the business rules and retrieve data form the data layer: Public Class Companies Public Shared Function CreateCompany() As ICompany Dim factory as New MyCompany.Data.CompanyFactory Return factory.CreateCompany() End Function End Class Any opinions/suggestions would be greatly appreciated.

  • moment.js work out time left

    - by user1503606
    I am trying to get my head around the moment.js library as it seems more stable than the jquery one and the jquery date one is output console errors. http://momentjs.com/docs/#/manipulating/ What i am trying to do is do a countdown to work out the time left from now. example i have var countDownTill = '2012-11-19 00:00:00 +0000'; document.write(moment(countDownTill).diff(moment(), 'months') + " months<br>"); document.write(moment(countDownTill).diff(moment(), 'weeks') + " weeks<br>"); document.write(moment(countDownTill).diff(moment(), 'days') + " days<br>"); which will output 0 months 1 weeks 4 days but its not working out overall its doing it individuals for each value (days,weeks,months) so if i up the date by say 12 months like below. var countDownTill = '2013-11-19 00:00:00 +0000'; document.write(moment(countDownTill).diff(moment(), 'months') + " months<br>"); document.write(moment(countDownTill).diff(moment(), 'weeks') + " weeks<br>"); document.write(moment(countDownTill).diff(moment(), 'days') + " days<br>"); it outputs. 12 months 53 weeks 369 days where as i am trying to get it to output 12 months 2 weeks 5 days example here http://jsfiddle.net/fDmWH/3/

  • Get Mechanize to handle cookies from an arbitrary POST (to log into a website programmatically)

    - by Horace Loeb
    I want to log into https://www.t-mobile.com/ programmatically. My first idea was to use Mechanize to submit the login form: However, it turns out that this isn't even a real form. Instead, when you click "Log in" some javascript grabs the values of the fields, creates a new form dynamically, and submits it. "Log in" button HTML: <button onclick="handleLogin(); return false;" class="btnBlue" id="myTMobile-login"><span>Log in</span></button> The handleLogin() function: function handleLogin() { if (ValidateMsisdnPassword()) { // client-side form validation logic var a = document.createElement("FORM"); a.name = "form1"; a.method = "POST"; a.action = mytmoUrl; // defined elsewhere as https://my.t-mobile.com/Login/LoginController.aspx var c = document.createElement("INPUT"); c.type = "HIDDEN"; c.value = document.getElementById("myTMobile-phone").value; // the value of the phone number input field c.name = "txtMSISDN"; a.appendChild(c); var b = document.createElement("INPUT"); b.type = "HIDDEN"; b.value = document.getElementById("myTMobile-password").value; // the value of the password input field b.name = "txtPassword"; a.appendChild(b); document.body.appendChild(a); a.submit(); return true } else { return false } } I could simulate this form submission by POSTing the form data to https://my.t-mobile.com/Login/LoginController.aspx with Net::HTTP#post_form, but I don't know how to get the resultant cookie into Mechanize so I can continue to scrape the UI available when I'm logged in. Any ideas?

  • Two network interfaces and two IP addresses on the same subnet in Linux

    - by Scott Duckworth
    I recently ran into a situation where I needed two IP addresses on the same subnet assigned to one Linux host so that we could run two SSL/TLS sites. My first approach was to use IP aliasing, e.g. using eth0:0, eth0:1, etc, but our network admins have some fairly strict settings in place for security that squashed this idea: They use DHCP snooping and normally don't allow static IP addresses. Static addressing is accomplished by using static DHCP entries, so the same MAC address always gets the same IP assignment. This feature can be disabled per switchport if you ask and you have a reason for it (thankfully I have a good relationship with the network guys and this isn't hard to do). With the DHCP snooping disabled on the switchport, they had to put in a rule on the switch that said MAC address X is allowed to have IP address Y. Unfortunately this had the side effect of also saying that MAC address X is ONLY allowed to have IP address Y. IP aliasing required that MAC address X was assigned two IP addresses, so this didn't work. There may have been a way around these issues on the switch configuration, but in an attempt to preserve good relations with the network admins I tried to find another way. Having two network interfaces seemed like the next logical step. Thankfully this Linux system is a virtual machine, so I was able to easily add a second network interface (without rebooting, I might add - pretty cool). A few keystrokes later I had two network interfaces up and running and both pulled IP addresses from DHCP. But then the problem came in: the network admins could see (on the switch) the ARP entry for both interfaces, but only the first network interface that I brought up would respond to pings or any sort of TCP or UDP traffic. After lots of digging and poking, here's what I came up with. It seems to work, but it also seems to be a lot of work for something that seems like it should be simple. Any alternate ideas out there? Step 1: Enable ARP filtering on all interfaces: # sysctl -w net.ipv4.conf.all.arp_filter=1 # echo "net.ipv4.conf.all.arp_filter = 1" >> /etc/sysctl.conf From the file networking/ip-sysctl.txt in the Linux kernel docs: arp_filter - BOOLEAN 1 - Allows you to have multiple network interfaces on the same subnet, and have the ARPs for each interface be answered based on whether or not the kernel would route a packet from the ARP'd IP out that interface (therefore you must use source based routing for this to work). In other words it allows control of which cards (usually 1) will respond to an arp request. 0 - (default) The kernel can respond to arp requests with addresses from other interfaces. This may seem wrong but it usually makes sense, because it increases the chance of successful communication. IP addresses are owned by the complete host on Linux, not by particular interfaces. Only for more complex setups like load- balancing, does this behaviour cause problems. arp_filter for the interface will be enabled if at least one of conf/{all,interface}/arp_filter is set to TRUE, it will be disabled otherwise Step 2: Implement source-based routing I basically just followed directions from http://lartc.org/howto/lartc.rpdb.multiple-links.html, although that page was written with a different goal in mind (dealing with two ISPs). Assume that the subnet is 10.0.0.0/24, the gateway is 10.0.0.1, the IP address for eth0 is 10.0.0.100, and the IP address for eth1 is 10.0.0.101. Define two new routing tables named eth0 and eth1 in /etc/iproute2/rt_tables: ... top of file omitted ... 1 eth0 2 eth1 Define the routes for these two tables: # ip route add default via 10.0.0.1 table eth0 # ip route add default via 10.0.0.1 table eth1 # ip route add 10.0.0.0/24 dev eth0 src 10.0.0.100 table eth0 # ip route add 10.0.0.0/24 dev eth1 src 10.0.0.101 table eth1 Define the rules for when to use the new routing tables: # ip rule add from 10.0.0.100 table eth0 # ip rule add from 10.0.0.101 table eth1 The main routing table was already taken care of by DHCP (and it's not even clear that its strictly necessary in this case), but it basically equates to this: # ip route add default via 10.0.0.1 dev eth0 # ip route add 130.127.48.0/23 dev eth0 src 10.0.0.100 # ip route add 130.127.48.0/23 dev eth1 src 10.0.0.101 And voila! Everything seems to work just fine. Sending pings to both IP addresses works fine. Sending pings from this system to other systems and forcing the ping to use a specific interface works fine (ping -I eth0 10.0.0.1, ping -I eth1 10.0.0.1). And most importantly, all TCP and UDP traffic to/from either IP address works as expected. So again, my question is: is there a better way to do this? This seems like a lot of work for a seemingly simple problem.

  • Should primitive types or non-primitive types be preferred in Java interfaces?

    - by Greg Mattes
    (I thought I once read something about this in a book, but now I'm not sure where to find it. If this question reminds you of some material that you've read, please post a reference!) What are the pros and the cons of primitives in interfaces? In other words, is one of these preferable to the other and why? Perhaps one is preferable to the other in certain contexts? public interface Foo { int getBar(); } or public interface Foo { Integer getBar(); } Similarly: public interface Boz { void someOperation(int parameter); } or public interface Boz { void someOperation(Integer parameter); } Obviously there's the issue of having to deal with nulls in the non-primitive case, but are there deeper concerns?

  • Scala method where type of second parameter equals part of generic type from first parameter

    - by ifischer
    I want to create a specific generic method in Scala. It takes two parameters. The first is of the type of a generic Java Interface (it's from the JPA criteria query). It currently looks like this: def genericFind(attribute:SingularAttribute[Person, _], value:Object) { ... } // The Java Interface which is the type of the first parameter in my find-method: public interface SingularAttribute<X, T> extends Attribute<X, T>, Bindable<T> Now i want to achieve the following: value is currently of type java.lang.Object. But I want to make it more specific. Value has to be the of the same type as the placeholder "_" from the first parameter (and so represents the "T" in the Java interface). Is that somehow possible, and how? BTW Sorry for the stupid question title (any suggestions?)

  • NSTextView's adjustScroll method

    - by Mike
    I'm trying to implement typewriter scrolling in my Cocoa text editor, keeping the insertion point centered vertically in its scrollview. Toward this end, I have subclassed NSClipView to provide a scrollToPointWithoutConstraint method, which scrolls the document to a specified point without calling constrainScrollPoint. This is necessary because for short documents the insertion point can't be centered unless we scroll beyond the document's bounds. This seems reasonably straightforward so far and does what I want. The problem comes in when I try to scroll using the scroll bars. If I'm scrolled to the end of the document, such that part of the scroll view contains an area outside the document's bounds, trying to scroll up by a small increment causes the scroll view to jump, immediately clamping to the document's actual bounds. I gather that I might need to subclass NSTextView and override the adjustScroll method; this is where my actual question begins. The proposedVisibleRect that is passed to adjustScroll already has its dimensions adjusted so that they lie within the document's actual bounds. Is there a way that I can change the value of proposedVisibleRect before adjustScroll is called? Alternatively, am I going about this entirely wrong? Any suggestions would be greatly appreciated at this point.

  • How to mock a RIA service

    - by Budda
    Is there any ability to mock methods that are provided with RIA Services? I would like to test my Silverlight App without communication to the server side... I see a following approach: create a separate interface; add it to "base classes" for my RiaService; define each autogenerated RIA-method in this interface; insert dependency so that my "functionality" will depend not from the RiaService, but from the interface that is implemented with RiaService. But for this case I see a problem: how to keep my interface in the auto-generated files? ANy thoughts are welcome.

  • Problem with dropdownbox length

    - by vikitor
    Hello, I'm creating a javascript method that populates lists depending on a radio button selected previously. As it depends on animals or plants to populate it, my problem comes when I have to populate it after it's already been populated. I mean, the plants dropdownlist has 88 elements, and the animals is 888, when I try to come back from animals to plants, I get some of the animals. I know that my controller method is working properly because it returns the values I select, so the problem is the javascript method. Here is the code: if(selector == "sOrder") alert(document.getElementById(selector).options.length); for (i = 0; i < document.getElementById(selector).options.length; i++) { document.getElementById(selector).remove(i); } if (selector == "sOrder") alert(document.getElementById(selector).options.length); document.getElementById(selector).options[0] = new Option("-select-", "0", true, true); for (i = 1; i <= data.length; i++) { document.getElementById(selector).options[i] = new Option(data[i - 1].taxName, data[i - 1].taxRecID);} Here is the strange thing, when I enter the method I try to erase all the elements of the dropdownlist in order to populate it afterwards. As sOrder is the same selector I had previously selected, I get the elements, the thing is that the first alert I get the proper result, 888, but in the second alert, I should get a 0 right? It shows 444, so when I populate it again it just overrides the first 88 plants and then animals till 444. What am I doing wrong? Thank you all in advance, Victor

  • Get Mechanize to handle cookies from an arbitrary POST (to log into https://www.t-mobile.com/ progra

    - by Horace Loeb
    I want to log into https://www.t-mobile.com/ programmatically. My first idea was to use Mechanize to submit the login form: However, it turns out that this isn't even a real form. Instead, when you click "Log in" some javascript grabs the values of the fields, creates a new form dynamically, and submits it. "Log in" button HTML: <button onclick="handleLogin(); return false;" class="btnBlue" id="myTMobile-login"><span>Log in</span></button> The handleLogin() function: function handleLogin() { if (ValidateMsisdnPassword()) { // client-side form validation logic var a = document.createElement("FORM"); a.name = "form1"; a.method = "POST"; a.action = mytmoUrl; // defined elsewhere as https://my.t-mobile.com/Login/LoginController.aspx var c = document.createElement("INPUT"); c.type = "HIDDEN"; c.value = document.getElementById("myTMobile-phone").value; // the value of the phone number input field c.name = "txtMSISDN"; a.appendChild(c); var b = document.createElement("INPUT"); b.type = "HIDDEN"; b.value = document.getElementById("myTMobile-password").value; // the value of the password input field b.name = "txtPassword"; a.appendChild(b); document.body.appendChild(a); a.submit(); return true } else { return false } } I could simulate this form submission by POSTing the form data to https://my.t-mobile.com/Login/LoginController.aspx with Net::HTTP#post_form, but I don't know how to get the resultant cookie into Mechanize so I can continue to scrape the UI available when I'm logged in. Any ideas?

  • Can I constrain a template parameter class to implement the interfaces that are supported by other?

    - by K. Georgiev
    The name is a little blurry, so here's the situation: I'm writing code to use some 'trajectories'. The trajectories are an abstract thing, so I describe them with different interfaces. So I have a code as this: namespace Trajectories { public interface IInitial < Atom > { Atom Initial { get; set; } } public interface ICurrent < Atom > { Atom Current { get; set; } } public interface IPrevious < Atom > { Atom Previous { get; set; } } public interface ICount < Atom > { int Count { get; } } public interface IManualCount < Atom > : ICount < Atom > { int Count { get; set; } } ... } Every concrete implementation of a trajectory will implement some of the above interfaces. Here's a concrete implementation of a trajectory: public class SimpleTrajectory < Atom > : IInitial < Atom >, ICurrent < Atom >, ICount < Atom > { // ICount public int Count { get; private set; } // IInitial private Atom initial; public Atom Initial { get { return initial; } set { initial = current = value; Count = 1; } } // ICurrent private Atom current; public Atom Current { get { return current; } set { current = value; Count++; } } } Now, I want to be able to deduce things about the trajectories, so, for example I want to support predicates about different properties of some trajectory: namespace Conditions { public interface ICondition &lt Atom, Trajectory &gt { bool Test(ref Trajectory t); } public class CountLessThan &lt Atom, Trajectory &gt : ICondition &lt Atom, Trajectory &gt where Trajectory : Trajectories.ICount &lt Atom &gt { public int Value { get; set; } public CountLessThan() { } public bool Test(ref Trajectory t) { return t.Count &lt Value; } } public class CurrentNormLessThan &lt Trajectory &gt : ICondition &lt Complex, Trajectory &gt where Trajectory : Trajectories.ICurrent &lt Complex &gt { public double Value { get; set; } public CurrentNormLessThan() { } public bool Test(ref Trajectory t) { return t.Current.Norm() &lt Value; } } } Now, here's the question: What if I wanted to implement AND predicate? It would be something like this: public class And &lt Atom, CondA, TrajectoryA, CondB, TrajectoryB, Trajectory &gt : ICondition &lt Atom, Trajectory &gt where CondA : ICondition &lt Atom, TrajectoryA &gt where TrajectoryA : // Some interfaces where CondB : ICondition &lt Atom, TrajectoryB &gt where TrajectoryB : // Some interfaces where Trajectory : // MUST IMPLEMENT THE INTERFACES FOR TrajectoryA AND THE INTERFACES FOR TrajectoryB { public CondA A { get; set; } public CondB B { get; set; } public bool Test(ref Trajectory t){ return A.Test(t) && B.Test(t); } } How can I say: support only these trajectories, for which the arguments of AND are ok? So I can be able to write: var vand = new CountLessThan(32) & new CurrentNormLessThan(4.0); I think if I create an orevall interface for every subset of interfaces, I could be able to do it, but it will become quite ugly.

  • Disassembling with python - no easy solution?

    - by Abc4599
    Hi, I'm trying to create a python script that will disassemble a binary (a Windows exe to be precise) and analyze its code. I need the ability to take a certain buffer, and extract some sort of struct containing information about the instructions in it. I've worked with libdisasm in C before, and I found it's interface quite intuitive and comfortable. The problem is, its Python interface is available only through SWIG, and I can't get it to compile properly under Windows. At the availability aspect, diStorm provides a nice out-of-the-box interface, but it provides only the Mnemonic of each instruction, and not a binary struct with enumerations defining instruction type and what not. This is quite uncomfortable for my purpose, and will require a lot of what I see as spent time wrapping the interface to make it fit my needs. I've also looked at BeaEngine, which does in fact provide the output I need, a struct with binary info concerning each instruction, but its interface is really odd and counter-intuitive, and it crashes pretty much instantly when provided with wrong arguments. The CTypes sort of ultimate-death-to-your-python crashes. So, I'd be happy to hear about other solutions, which are a little less time consuming than messing around with djgcc or mingw to make SWIGed libdisasm, or writing an OOP wrapper for diStorm. If anyone has some guidance as to how to compile SWIGed libdisasm, or better yet, a compiled binary (pyd or dll+py), I'd love to hear/have it. :) Thanks ahead.

  • some help required while working on java and cigwin together .

    - by Hippo
    Hello .. I am new to java and also cygwin . I do not have in detailed knowledge of both . I need some help.. I simple steps i will try to explain my problem. 1) I am working on tinyOS . its open source OS , used for wireless sensor networks. It provides java libraries to work on communication (PC to sensor) 2) I am working on windows xp environment through cigwin. 3) I am developing an application . THis application requires one java interface called "Serial Forwarder" , which is readily available in libraries provided. Previously i used to start this interface manually (by entering command *"java net.tinyos.sf.SerialForwarder ")*and then my application which uses this interface. But now i want to make my application independent . User need know about this background cygwin commands . 4) So in my java application i used "Runtime.getRuntime().exec( "java net.tinyos.sf.SerialForwarder)" . 5) This i neither giving any error nor starting the interface. Am I going on right way ? When i am using runtime execute command , how can i make sure that this command is called through cigwin interface ? Also .. if i want to write .bat file .. i which i can give commands which will be executed .. how can i make sure that those commands are given through cigwin .. and not through cmd.exe .. Please help . me .

  • GWT CssResource Customization

    - by Eric Landry
    I'm writing a GWT widget using UIBinder and MVP. The widget's default styles are defined in TheWidgetView.ui.xml: <ui:style type="com.widgetlib.spinner.display.TheWidgetView.MyStyle"> .textbox { border: 1px solid #red; } .important { font-weight: bold; } </ui:style> The widget's CssResource interface is defined in TheWidgetView.java: public class TheWidgetView extends HorizontalPanel implements TheWidgetPresenter.Display { // ... some code @UiField MyStyle style; public interface MyStyle extends CssResource { String textbox(); String important(); } // ... more code } I'd like the consumer of this widget to be able to customize part of the widget's styles and to have this in their MyExample.ui.xml: <ui:style type="com.consumer.MyExample.MyStyle"> .textbox { border: 2px solid #black; } </ui:style> And this be their MyExample.java: public class MyExample extends Composite { // ... some code @UiField MyStyle style; interface MyStyle extends TheWidgetView.MyStyle{ String textbox(); } // ... more code } Is there a way that my widget can have default styles, but that the consumer of the widget can override one of them? When an interface extends TheWidgetView.MyStyle, the of the widget consumer needs to define all the styles listed in that parent interface. I've seen some widget libraries have the widget's constructor take in a ClientBundle as parameter, which I suppose could apply to CssResource. Although, I'm not sure how I'd pass in this style object in a constructor invoked by UIBinder. Thanks much in advance!
