  • handling refrence to pointers/double pointers using SWIG [C++ to Java]

    - by Siddu
    My code has an interface like class IExample { ~IExample(); //pure virtual methods ...}; a class inheriting the interface like class CExample : public IExample { protected: CExample(); //implementation of pure virtual methods ... }; and a global function to create object of this class - createExample( IExample *& obj ) { obj = new CExample(); } ; Now, I am trying to get Java API wrapper using SWIG, the SWIG generated interface has a construcotr like - IExample(long cPtr, boolean cMemoryOwn) and global function becomes createExample(IExample obj ) The problem is when i do, IExample exObject = new IExample(LogFileLibraryJNI.new_plong(), true /*or false*/ ); createExample( exObject ); The createExample(...) API at C++ layer succesfully gets called, however, when call returns to Java layer, the cPtr (long) variable does not get updated. Ideally, this variable should contain address of CExample object. I read in documentation that typemaps can be used to handle output parameters and pointer references as well; however, I am not able to figure out the suitable way to use typemaps to resolve this problem, or any other workaround. Please suggest if i am doing something wrong, or how to use typemap in such situation?

  • Grails JSON array

    - by armandino
    I'm converting a list of Foo objects to a JSON string. I need to parse the JSON string back into a list of Foos. However in the following example, parsing gives me a list of JSONObjects instead of Foos. Example List list = [new Foo("first"), new Foo("second")] def jsonString = (list as JSON).toString() List parsedList = JSON.parse(jsonString) as List println parsedList[0].getClass() // org.codehaus.groovy.grails.web.json.JSONObject How can I parse it into Foos instead? Thanks in advance.

  • Hide/ change width/ change position of UIButton based on device type

    - by Giles Van Gruisen
    I'm using the new in-app SMS features in my iPhone app, but obviously iPod Touches aren't able to send and receive SMS without support of a third party app. I know all well how to detect the device and how to hide a UIButton, but what I do not know is how to change the width of the others. Above are the three icons. The one on the far rights needs to be hidden on an iPod Touch, and the other two need to adjust size/ position to fill the remaining space. Any tips on programatically changing the position and width of a UIButton is greatly appreciated. Thanks!

  • How do I surpress maven assembly plugin skipping files that are already added? Or allow overwrite?

    - by gmale
    Hello, For weeks, I've been wrestling with maven, getting it to deploy our project "properly." I'm almost done but I have one stubborn little problem: When I use the maven assembly plugin with the "directory" goal as in mvn assembly:directory I get LOTS of console output like the following: [INFO] tomcat/conf already added, skipping  [INFO] tomcat/conf/Catalina already added, skipping  [INFO] tomcat/conf/Catalina/localhost already added, skipping  [INFO] tomcat/webapps already added, skipping I've written my own assembly descriptor that basically copies several FileSets into various sub-directories within our deploy directory. Messages like the ones above appear whenever a file from one FileSet is being copied to a location in which another FileSet has already created the basic directory structure (and some "default" files that can be overwritten). So, I'm having a hard time figuring out: How do I either 1) Suppress these messages (but only the "already added" messages) or 2) allow for overwrite?

  • Proper way to add record to many to many relationship in Django

    - by blcArmadillo
    First off, I'm planning on running my project on google app engine so I'm using djangoappengine which as far as I know doesn't support django's ManyToManyField type. Because of this I've setup my models like this: from django.db import models from django.contrib.auth.models import User class Group(models.Model): name = models.CharField(max_length=200) class UserGroup(models.Model): user = models.ForeignKey(User) group = models.ForeignKey(Group) On a page I have a form field where people can enter a group name. I want the results from this form field to create a UserGroup object for the user - group combination and if the group doesn't yet exist create a new Group object. At first I started putting this logic in the UserGroup class with a add_group method but quickly realized that it doesn't really make sense to put this in the UserGroup class. What would the proper way of doing this be? I saw some stuff about model managers. Is this what those are for?

  • How to get only one rounded corner with border-radius htc hack and MSIE v:roundrect?

    - by aarreoskari
    I have a problem with partially rounded corners. See the first working example for most browsers: .box { display: block; width: 100px; height: 100px; border: 1px solid black; background-color: yellow; -moz-border-radius-bottomright: 10px; -webkit-border-bottom-right-radius: 10px; } You can see that only bottom right corner should be rounded. Natural choice would be adding a border-radius.htc hack inside a conditional IE statement: .box { border-bottom-right-radius: 20px; behavior:url(border-radius.htc); } This is not working because border-radius.htc file is only accessing normal border-radius value (this.currentStyle['border-radius']). VML used by the hack is roundrect which only supports one percentage value for arcsize. So I was wondering if there is any other way around the problem by using some other VML elements? Another problem is that htc-file doesnt's support borders but that can be fixed with VML's stroked attribute. Nifty corners for example doesn't work well with corners at all.

  • Replace CAPICOM with .NET, validate certificate

    - by Zaky
    Hi My component is responsible for downloading files from the server. As part of file validation I have used CAPICOM (SignedCode object) to validate if a certificate contains a specific string and call to Validate method of the SignedCode object. In case the file contains certificate without a requested string in the name, user was prompted if he trust this file. Since CAPICOM going to be deprecated by Microsoft, I need to implement these logic using .NET libraries. How I can get the same functionality using .NET libraries? Is there any example on the web? Thanks Zaky

  • Visual Studio 2010 crashes nearly every time when closing

    - by Andrei Drynov
    Mostly it happens if we open a team project from tfs 2008 or tfs 2010, but crashes can happen any time. When VS is closing down, it crashes nearly every time. Tried trial RTM and our MSDN download - same story. Tried on three different PCs - same issue. Tried on 32 and 64-bit Windows 7 and Windows Server 2008 R2 - crashes. Is it just our luck or does it happen to you to?

  • MSBuild: building website using AspNetCompiler - adding references?

    - by Tom Morgan
    Hi, I'm attempting to build a ASP.NET website using MSBuild - specifically the AspNetCompiler tag. I know that, for my project, I need to add some references. Within Visual Studio I have several references, one is a project reference and the others are some DLLS (AjaxControlToolkit etc). I'm happy not referencing the project and referencing the DLL instead - however I just can't work out how to add a reference. I've looked up and down and this is what I've found so far: <Target Name = "PrecompileWeb"> <AspNetCompiler VirtualPath = "DeployTemp" PhysicalPath = "D:\AutoBuild\CruiseControl\Projects\Websites\MyCompany\2.0.0\WorkingDirectory\VSS" TargetPath = "D:\AutoBuild\CruiseControl\Projects\Websites\MyCompany\2.0.0\PreCompiled" Force = "true" Debug = "true" Updateable = "true"/> </Target> Also - I've picked up this bit of code from around the web somewhere, which I thought might help: <ItemGroup> <Reference Include="My.Web.DataEngine, Culture=neutral, processorArchitecture=MSIL"> <SpecificVersion>False</SpecificVersion> <HintPath>D:\AutoBuild\CruiseControl\Projects\Components\My.Web.DataEngine\bin\Debug\My.Web.DataEngine.dll</HintPath> </Reference> </ItemGroup> What I want to do is add a attribute to the AspNetCompiler tag, something like: References="@(Reference)" but MSBuild isn't very happy about this. I've been a bit stuck in not being able to find decent references on doing this anywhere: so I'd really apprechiate some pointers or reference material etc. (or just the answer!) Thanks for you help. -tom

  • Silverlight WCF netTcpBinding problem

    - by JontyMC
    Trying to call a WCF with a netTcpBinding via Silverlight, I am getting the error: "TCP error code 10013: An attempt was made to access a socket in a way forbidden by its access permissions.. This could be due to attempting to access a service in a cross-domain way while the service is not configured for cross-domain access. You may need to contact the owner of the service to expose a sockets cross-domain policy over HTTP and host the service in the allowed sockets port range 4502-4534." My WCF service is hosted in IIS7, bound to: http://localhost.myserivce.com on port 80 and net.tcp on port 4502 I can see http://localhost.myserivce.com/myservice.svc if I browse to it (my hosts file is pointing this domain to localhost).

  • tcpdump on dd-wrt router

    - by Senica Gonzalez
    I'm trying to capture packets from two devices on my network. I have tcpdump installed on my dd-wrt router and working correctly. However, the only packets I capture are broadcast packets when using a tcpdump statement that states only those two devices ./tcpdump -w /tmp/capture.pcap dst 192.168.3.105 or src 192.168.3.105 or dst 192.168.3.136 or src 192.168.3.136 I'm capturing on intefface br0. Is that correct? Both devices are plugged in directly to the ports 1 and 2 with ip addresses 192.168.3.105 and 192.168.3.136 respectively. Do I need to set br0 in promiscuous mode? A little stuck. Thanks.

  • Installing Visual Studio 2003 on Windows 7 64-bit

    - by Cole Shelton
    My team is currently supporting a 1.1 app and we are installing VS.NET 2003 on Windows 7. We haven't had any issues on the 32-bit machines, but FrontPage Server Extensions are failing to install on my 64-bit machine. Others on the Interwebs say that they have done this successfully, so I wanted to know if anyone here has and if they know of a solution. The specific issue is that FPSE (to clarify, I'm installing "FrontPage 2002 Server Extensions for IIS 7.0") fails to install correctly. In EventViewer I get the error: Microsoft FrontPage Server Extensions: Error #3004f Message: Unable to read configuration information for Microsoft Internet Information Server: ImpersonateLoggedOnUser Error. I've looded for errors with ImpersonateLoggedOnUser on 64-bit and did find a case where it fails on 64-bit when UAC is turned off (which I did have it off). I turned UAC back on, ran command prompt as administrator, and ran msiexec on the FPSE package. Still no dice. I have followed this tutorial (and the others it points to) for installing: http://frankbuchan.blogspot.com/2009/08/visual-studio-2003-under-windows-7.html

  • EF4 - possible to mock ObjectContext for unit testing?

    - by steve.macdonald
    Can it be done without using TypeMock Islolator? I've found a few suggestions online such as passing in a metadata only connection string, however nothing I've come across besides TypeMock seems to truly allow for a mock ObjectContext that can be injected into services for unit testing. Do I plunk down the $$ for TypeMock, or are there alternatives? Has nobody managed to create anything comparable to TypeMock that is open source?
