  • How do I code Citrix web sites to use a Secure Gateway (CSG)?

    - by RAVolt
    I'm using Citrix's sample code as a base and trying to get it to generate ICA files that direct the client to use their Secure Gateway (CSG) provider. My configuration is that the ICA file's server address is replaced with a CSG ticket and traffic is forced to go to the CSG. The challenge is that both the Citrix App Server (that's providing the ICA session on 1494) and the CSG have to coordinate through a Secure Ticket Authority (STA). That means that my code needs to talk to the STA as it creates the ICA file because STA holds a ticket that the CSG needs embedded into the ICA file. Confusing? Sure! But it's much more secure. The pre-CSG code looks like this: AppLaunchInfo launchInfo = (AppLaunchInfo)userContext.launchApp(appID, new AppLaunchParams(ClientType.ICA_30)); ICAFile icaFile = userContext.convertToICAFile(launchInfo, null, null); I tried to the SSLEnabled information to the ICA generation, but it was not enough. here's that code: launchInfo.setSSLEnabled(true); launchInfo.setSSLAddress(new ServiceAddress("CSG URL", 443)); Now, it looks like I need to register the STA when I configure my farm: ConnectionRoutingPolicy policy = config.getDMZRoutingPolicy(); policy.getRules().clear(); //Set the Secure Ticketing Authorities (STAs). STAGroup STAgr = new STAGroup(); STAgr.addSTAURL(@"http://CitrixAppServerURL/scripts/ctxsta.dll"); //creat Secure Gateway conenction SGConnectionRoute SGRoute = new SGConnectionRoute(@"https://CSGURL"); SGRoute.setUseSessionReliability(false); SGRoute.setGatewayPort(80); SGRoute.setTicketAuthorities(STAgr); // add the SGRoute to the policy policy.setDefault(SGRoute); This is based on code I found on the Citrix Forums; however, it breaks my ability to connect with the Farm and get my application list! Can someone point me to an example of code that works? Or a reference document?

  • Find does not work in Expect Send command

    - by Sharjeel Sayed
    I run this bash command to display contents of somefile.cf in a Weblogic domain directory. find $(/usr/ucb/ps auwwx | grep weblogic | tr ' ' '\n' | grep security.policy | grep domain | awk -F'=' '{print $2}' | sed -e 's/weblogic.policy//' -e 's/security\///' -e 's/dep\///' | awk -F'/' '{print "/"$2"/"$3"/"$4"/somefile.cf"}' | sort | uniq) 2> /dev/null -exec ls {} \; -exec cat {} \; I tried incorporating this in an expect script and also escaped some special characters which would throw an error in expect but its still not working. send "echo ; echo 'Weblogic somefile.cf:' ; find \$(/usr/ucb/ps auwwx | grep weblogic | tr ' ' '\n' | grep security.policy | grep domain | awk -F'=' '{print \$2}' | sed -e 's/weblogic.policy//' -e 's/security\\///' -e 's/dep\\///' | awk -F'/' '{print "/"\$2"/"\$3"/"\$4"/somefile.cf"}' | sort | uniq) 2> /dev/null -exec ls {} \\; -exec cat {} \\; ; echo\r" I guess it needs some more escaping of special characters or probably I dint escape the existing ones correctly. Any help would be appreciated.

  • WPF: ListView inside LIstViewItem: How to support button_click

    - by Bartek
    Hi I have problem with using buttons that are placed in the itemtemplate of the listview which is placed in the itemtemplate of the outer listview. I'll try to simplify the code to show only the idea. I have a objects collection which looks like this: Main object contains a list of innerObjects. Every innerObject contains a list of objects that contain some strings. mainObject listItem innerListItem string string innerListItem string string listItem innerListItem string string I set a mainObject as a itemsSource to the ListView. This listView has a ItemTemplate. This ItemTemplate contains some buttons and inner ListView. Inner ListView also has the item template that contains a button (deleteButton). Pressing this deleteButton I want to delete items (innerListItem) for which this button was created. I can use such functionality when I have a sigle listView. private void clearAndList_Click(object sender, RoutedEventArgs e) { DependencyObject dep = (DependencyObject)e.OriginalSource; while ((dep != null) && !(dep is System.Windows.Controls.ListViewItem)) { dep = VisualTreeHelper.GetParent(dep); } if (dep == null) { return; } ANDconditionsList andList = (ANDconditionsList)ConditionsList.ItemContainerGenerator.ItemFromContainer(dep); orConditionsList.RemoveConditionsSet(andList); } I can't use the same functionality because I can only use the name of the ConditionsList which is the mail listview. The idea is to find the innerlistview and use it instead of ConditionsList, however I don't know if it will work. If anyone have some samples concerning using listview in listview or how to operate the button in a different way please help me

  • What are some Java memory management best practices?

    - by Ascalonian
    I am taking over some applications from a previous developer. When I run the applications through Eclipse, I see the memory usage and the heap size increase a lot. Upon further investigation, I see that they were creating an object over-and-over in a loop as well as other things. I started to go through and do some clean up. But the more I went through, the more questions I had like "will this actually do anything?" For example, instead of declaring a variable outside the loop mentioned above and just setting its value in the loop... they created the object in the loop. What I mean is: for(int i=0; i < arrayOfStuff.size(); i++) { String something = (String) arrayOfStuff.get(i); ... } versus String something = null; for(int i=0; i < arrayOfStuff.size(); i++) { something = (String) arrayOfStuff.get(i); } Am I incorrect to say that the bottom loop is better? Perhaps I am wrong. Also, what about after the second loop above, I set "something" back to null? Would that clear out some memory? In either case, what are some good memory management best practices I could follow that will help keep my memory usage low in my applications? Update: I appreciate everyones feedback so far. However, I was not really asking about the above loops (although by your advice I did go back to the first loop). I am trying to get some best practices that I can keep an eye out for. Something on the lines of "when you are done using a Collection, clear it out". I just really need to make sure not as much memory is being taken up by these applications.

  • extracting SWF gives compiler errors in adobe flash CS4

    - by Andy
    Hey, I have been given an SWF to edit a link in the AS code. The fact is the SWF uses some XML that is generated (actually retrieved) by PHP code from a database. menuXML.load("/sub/page/dynamic.php?genre=" + genre); so the point is we can use the same SWF 'mainfraim' and fill them with different animations/sources based on the link provided in dynamic.php?genre=### Now, I've used Flash Decompiler Gold to extract all files in the SWF and can open it again in Adobe Flash to edit it. When done I enter CTRL+ENTER and there are immediately 4 compiler errors!! Errors: 1x < Unexpected 'if' encountered 2x < Statement block must be terminated by '}' 1x < Ecpected a field name after '.' operator. How can these errors be present, when the original SWF works perfectly??! If I don't manage to solve this, I'll have to find out how to create an .php file the SWF tries to use which can select the proper resources (from a database I guess) to show them (using ?genre=###) Thanks!

  • Nested instances in C#

    - by user32848
    I'm trying to translate some C++ code for a neural net into C#. I first took the C++ code, from a 1993 book, and ran it. Then translated it using the STL and it ran again. Now I'm trying to get it into C# with Visual Web Developer 2008 Express. The original code used "friend" classes and I'm just trying to do the same making everything "public". The following code compiles but only gives null references when run: public class ineuron { public Double weight, activation; public ineuron(Double set_wt) { weight = set_wt; } ... public class netwrk { public oneuron onrn; public ineuron in1, in2, in3, in4; public netwrk( Double inp_1, Double inp_2, Double inp_3, Double inp_4 ) { ineuron in1 = new ineuron(inp_1); ineuron in2 = new ineuron(inp_2); ... and later, in some code called by a button push: netwrk ntw = new netwrk(i_n1, i_n2, i_n3, i_n4); Unfortunately, trying to use: ntw.in1.activation etc. leads to null reference runtime errors. What am I forgetting to do? Barney

  • Apache & SVN on Ubuntu - Post-commit hook fails silently, pre-commit hook "Permission Denied"

    - by Andy R
    I've been struggling for the past couple days to get post-commit email notifications working on my SVN server (running via HTTP with Apache2 on Ubuntu 9.10). SVN commits work fine, but for some reason the hooks are not being properly executed. Here are the configuration settings: - Users access the repo via HTTP with the apache dav_svn module (I created users/passwords via htpasswd in a dav_svn.passwd file). dav_svn.conf: <Location /svn/repos> DAV svn SVNPath /home/svn/repos AuthType Basic AuthName "Subversion Repository" AuthUserFile /etc/apache2/dav_svn.passwd Require valid-user </Location> I created a post-commit hook file that writes a simple message to a file in the repository root: /home/svn/repos/hooks/post-commit: #!/bin/sh REPOS="$1" REV="$2" /bin/echo 'worked' > ${REPOS}/postcommit.log I set the entire repository to be owned by www-data (the apache user), and assigned 755 permissions to the post-commit script when I test the post-commit script using the www-data user in an empty environment, it works: sudo -u www-data env - /home/svn/repos/hooks/post-commit /home/svn/repos 7 But when I commit on a client machine, the commit is successful, but the post-commit script does not seem to be executed. I also tried running a simple script for the pre-commit hook, and I get an error, even with an empty pre-commit script: "Commit failed (details follow): Can't create null stdout for hook '/home/svn/repos/hooks/pre-commit': Permission denied" I did a few searches on Google for this error and I presume that this is an issue with the apache user (www-data) not having adequate permissions, specifically to execute /dev/null. I also read that the reason post-commit fails silently is because that it doesn't report with stdout. Anyway, I've also tried giving the apache user (www-data) ownership of the entire repository, and edited the apache virtualhost to allow operations on the server root, and I'm still getting permission denied /etc/apache2/sites-available/primarydomain.conf <Directory /> Options FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> Any ideas/suggestions would be greatly appreciated! Thanks

  • Using MSADO15.DLL and C++ with MinGW/GCC on Windows Vista

    - by Eugen Mihailescu
    INTRODUCTION Hi, I am very new to C++, is my 1st statement. I have started initially with VC++ 2008 Express, I've notice that GCC becomes kind of standard so I am trying to make the right steps event from the beginning. I have written a piece of code that connects to MSSQL Server via ADO, on VC++ it's working like a charm by importing MSADO15.dll: #import "msado15.dll" no_namespace rename("EOF", "EndOfFile") Because I am going to move from VC++ I was looking for an alternative (eventually multi-platform) IDE, so I stick (for this time) with Code::Block (I'm using last nightly buil, SVN 6181). As compiler I choose to use GCC 3.4.5 (ported via MinGW 5.1.6), under Vista. I was trying to compile a simple "hello world" application with GCC that use/import the same msado15.dll (#import "c:\Program Files\Common Files\System\ADO\msado15.dll" no_namespace rename("EOF", "EndOfFile")) and I was surprised to see a lot of compile-time errors. I was expected that the #import compiler's directive will generate a library from "msado15.dll" so it can link to it later (link-edit time or whatever). Instead it was trying to read it as a normal file (like a header file,if you like) because it was trying to interprete each line in the DLL (which has a MZ signature): Example: Compiling: main.cpp E:\MyPath\main.cpp:2:64: warning: extra tokens at end of #import directive In file included from E:\MyPath\main.cpp:2: c:\Program Files\Common Files\System\ADO\msado15.dll:1: error: stray '\144' in program In file included from E:\MyPath\main.cpp:2: c:\Program Files\Common Files\System\ADO\msado15.dll:1:4: warning: null character(s) ignored c:\Program Files\Common Files\System\ADO\msado15.dll:1: error: stray '\3' in program c:\Program Files\Common Files\System\ADO\msado15.dll:1:6: warning: null character(s) ignored c:\Program Files\Common Files\System\ADO\msado15.dll:1: error: stray '\4' in program ... and so on. MY QUESTION Well, it is obvious that under this version of GCC the #import directive does not do the expected job (perhaps #import is not supported anymore by GCC), so finally my question: how to use the ADO to access MSSQL database on a C++ program compiled with GCC (v3.4.5)?

  • Render view to string followed by redirect results in exception

    - by Chris Charabaruk
    So here's the issue: I'm building e-mails to be sent by my application by rendering full view pages to strings and sending them. This works without any problem so long as I'm not redirecting to another URL on the site afterwards. Whenever I try, I get "System.Web.HttpException: Cannot redirect after HTTP headers have been sent." I believe the problem comes from the fact I'm reusing the context from the controller action where the call for creating the e-mail comes from. More specifically, the HttpResponse from the context. Unfortunately, I can't create a new HttpResponse that makes use of HttpWriter because the constructor of that class is unreachable, and using any other class derived from TextWriter causes response.Flush() to throw an exception, itself. Does anyone have a solution for this? public static string RenderViewToString( ControllerContext controllerContext, string viewPath, string masterPath, ViewDataDictionary viewData, TempDataDictionary tempData) { Stream filter = null; ViewPage viewPage = new ViewPage(); //Right, create our view viewPage.ViewContext = new ViewContext(controllerContext, new WebFormView(viewPath, masterPath), viewData, tempData); //Get the response context, flush it and get the response filter. var response = viewPage.ViewContext.HttpContext.Response; //var response = new HttpResponseWrapper(new HttpResponse // (**TextWriter Goes Here**)); response.Flush(); var oldFilter = response.Filter; try { //Put a new filter into the response filter = new MemoryStream(); response.Filter = filter; //Now render the view into the memorystream and flush the response viewPage.ViewContext.View.Render(viewPage.ViewContext, viewPage.ViewContext.HttpContext.Response.Output); response.Flush(); //Now read the rendered view. filter.Position = 0; var reader = new StreamReader(filter, response.ContentEncoding); return reader.ReadToEnd(); } finally { //Clean up. if (filter != null) filter.Dispose(); //Now replace the response filter response.Filter = oldFilter; } }

If creating the file manually is the way to go, is it just an empty file, or do i have to write something to it? Thanks and Regards.

  • Strange rare out-of-order data received using Indy

    - by Jim
    We're having a bizarre problem with Indy10 where two large strings (a few hundred characters each) that we send out one after the other are appearing at the other end intertwined oddly. This happens extremely infrequently. Each string is a complete XML message terminated with a LF and in general the READ process reads an entire XML message, returning when it sees the LF. The call to actually send the message is protected by a critical section around the call to the IOHandler's writeln method and so it is not possible for two threads to send at the same time. (We're certain the critical section is implemented/working properly). This problem happens very rarely. The symptoms are odd...when we send string A followed by string B what we received at the other end (on the rare occasions where we have failure) is the trailing section of string A by itself (i.e., there's a LF at the end of it) followed by the leading section of string A and then the entire string B followed by a single LF. We've verified that the "timed out" property is not true after the partial read - we log that property after every read that returns content. Also, we know there are no embedded LF characters in the string, as we explicitly replace all non-alphanumeric characters in the string with spaces before appending the LF and sending it. We have log mechanisms inside the critical sections on both the transmission and receiving ends and so we can see this behavior at the "wire". We're completely baffled and wondering (although always the lowest possibility) whether there could be some low-level Indy issues that might cause this issue, e.g., buffers being sent in the wrong order....very hard to believe this could be the issue but we're grasping at straws. Does anyone have any bright ideas?

  • what's the best way, using the TFS API, to add a label to a file?

    - by jcollum
    I'd like to add a label to a set of files using the TFS API. My code looks like this: VersionControlLabel label = new VersionControlLabel(this.vcServer, this.label, this.vcServer.AuthenticatedUser, this.labelScopeDirectory, this.labelComment); List<LabelItemSpec> labelSpecs = new List<LabelItemSpec>(); // iterate files and versions foreach (var fileAndVersion in this.filesAndVersions) { VersionSpec vs = null; Item i = null; // i have no idea why the itemspec is needed instead of the item and version... ItemSpec iSpec = new ItemSpec("{0}/{1}".FormatString(this.source, fileAndVersion.Key), RecursionType.None); GetItemAndVersionSpec(fileAndVersion.Key, fileAndVersion.Value, out vs, out i); labelSpecs.Add(new LabelItemSpec(iSpec, vs, false)); } this.vcServer.CreateLabel(label, labelSpecs.ToArray(), LabelChildOption.Merge); (there are some extension methods in there... this is all largely lifted from this blog post) The thing that concerns me is things like this in the MSDN docs: This enumeration supports the .NET Framework infrastructure and is not intended to be used directly from your code. So MSDN is telling me not to use that enumeration (LabelChildOption), which is afaik the only way to create a label and add it to a file. Is there a better way? Is this sort of a "grey" area in the TFS API?

  • Java exception handling in non sequential tasks (pattern/good practice)

    - by Hernán Eche
    There are some task that should't be done in parallel, (for example opening a file, reading, writing, and closing, there is an order on that...) But... Some task are more like a shoping list, I mean they could have a desirable order but it's not a must..example in communication or loading independient drivers etc.. For that kind of tasks, I would like to know a java best practice or pattern for manage exceptions.. The java simple way is: getUFO { try { loadSoundDriver(); loadUsbDriver(); loadAlienDetectorDriver(); loadKeyboardDriver(); } catch (loadSoundDriverFailed) { doSomethingA; } catch (loadUsbDriverFailed) { doSomethingB; } catch (loadAlienDetectorDriverFailed) { doSomethingC; } catch (loadKeyboardDriverFailed) { doSomethingD; } } But what about having an exception in one of the actions but wanting to try with the next ones?? I've thought this approach, but don't seem to be a good use for exceptions I don't know if it works, doesn't matter, it's really awful!! getUFO { Exception ex=null; try { try{ loadSoundDriver(); }catch (Exception e) { ex=e; } try{ loadUsbDriver(); }catch (Exception e) { ex=e; } try{ loadAlienDetectorDriver(); }catch (Exception e) { ex=e; } try{ loadKeyboardDriver() }catch (Exception e) { ex=e; } close the file; if(ex!=null) { throw ex; } } catch (loadSoundDriverFailed) { doSomethingA; } catch (loadUsbDriverFailed) { doSomethingB; } catch (loadAlienDetectorDriverFailed) { doSomethingC; } catch (loadKeyboardDriverFailed) { doSomethingD; } } seems not complicated to find a better practice for doing that.. I still didn't thanks for any advice

  • Use VersionControlExt.Explorer outside Visual Studio

    - by Ian
    Hi All, I'm developing a TFS tool to assist the developers in our company. This said tool needs to be able to "browse" the TFS server like in the Source Control Explorer. I believe that by using VersionControlExt.Explorer.SelectedItems, a UI will pop-up that will enable the user to browse the TFS server (please correct me if I'm wrong). However, VersionControlExt is only accessible when developing inside Visual Studio (aka Plugin). Unfortunately, I am developing a Windows Application that won;t run inside VS. So the question is, Can I use VersionControlExt outside of Visual Studio? If yes, how? Here's an attempt on using the Changset Details Dialog outside of Visual Studio string path = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location); Assembly vcControls = Assembly.LoadFile(path + @"\Microsoft.TeamFoundation.VersionControl.Controls.dll"); Assembly vcClient = Assembly.LoadFile(path + @"\Microsoft.TeamFoundation.VersionControl.Client.dll"); Type dialogChangesetDetailsType = vcControls.GetType("Microsoft.TeamFoundation.VersionControl.Controls.DialogChangesetDetails",true); Type[] ctorTypes = new Type[3] {vcClient.GetType("Microsoft.TeamFoundation.VersionControl.Client.VersionControlSever"), vcClient.GetType("Microsoft.TeamFoundation.VersionControl.Client.Changeset"), typeof(System.Boolean)}; ConstructorInfo ctorInfo = dialogChangesetDetailsType.GetConstructor(ctorTypes); Object[] ctorObjects = new Object[3] {VersionControlHelper.CurrentVersionControlServer, uc.ChangeSet, true}; Object oDialog = ctorInfo.Invoke(ctorObjects); dialogChangesetDetailsType.InvokeMember("ShowDialog", BindingFlags.InvokeMethod, null, oDialog, null);

  • Firefox extension is freezing Firefox until request is completed

Is there any mechanism to prevent freezing, so it works as expected? in XUL <statusbarpanel id="eee_label" tooltip="eee_tooltip" onclick="eee.retrieve_rate(event);"/> Javascript retrieve_rate: function(e) { var ajax = null; ajax = new XMLHttpRequest(); ajax.open('GET', 'http://site.com', false); ajax.onload = function() { if (ajax.status == 200) { var regexp = /blabla/g; var match = regexp.exec(ajax.responseText); while (match != null) { window.dump('Currency: ' + match[1] + ', Rate: ' + match[2] + ', Change: ' + match[3] + "\n"); if(match[1] == "USD") rate_USD = sprintf("%s:%s", match[1], match[2]); if(match[1] == "EUR") rate_EUR = sprintf("%s:%s", match[1], match[2]); if(match[1] == "RUB") rate_RUB = sprintf("%s/%s", match[1], match[2]); match = regexp.exec(ajax.responseText); } var rate = document.getElementById('eee_label'); rate.label = rate_USD + " " + rate_EUR + " " + rate_RUB; } else { } }; ajax.send(); I tried to put window.dump() right after ajax.send() and it dumped in the console also after the request is completed.

  • Firefox Extension Socket Transport

    - by Nathan
    Hey, I'm making a firefox extension and I'm currently trying to get it to send XML data over a local socket to another application that's listening on that socket. Does anyone know what I'm doing wrong in this? Its probably something simple and I'm just having a monday. Thanks. socketConn: function() { var httpLoc = window.top.getBrowser(). selectedBrowser.contentWindow.location.href; var outputData = '<?xml version="1.0"?>' + '<site_data>' + '<session_id></session_id>' + 'site_url>' + httpLoc + '</site_url>' + '<mime_type></mime_type>' + '<data_file>' + filePath + '</data_file>' + '<capture_mode></capture_mode>' + '</site_data>\n'; var transportService = Cc["@mozilla.org/network/socket-transport-service;1"] .getService(Ci.nsISocketTransportService); var transport = transportService.createTransport(["starttls"], 1,"localhost",currentPort, null); var outstream = transport.openOutputStream(0, 0, 0); outstream.write(outputData, outputData.length); var stream = transport.openInputStream(0, 0, 0); var instream = Cc["@mozilla.org/scriptableinputstream;1"] .createInstance(Ci.nsIScriptableInputStream); instream.init(stream); var dataListener = { data : "", onStartRequest: function(request, context){}, onStopRequest: function(request, context, status){ instream.close(); outstream.close(); }, onDataAvailable: function(request, context, inputStream, offset, count){ this.data += instream.read(count); }, };//end dataListener var pump = Cc["@mozilla.org/network/input-stream-pump;1"] .createInstance(Ci.nsIInputStreamPump); pump.init(stream, -1, -1, 0, 0, false); pump.asyncRead(dataListener, null); }//end socketConn Please ask questions about this if you don't understand what I'm trying to do with this.

  • How to handle EntityExistsException properly?

    - by Ivan Yatskevich
    I have two entities: Question and FavoritesCounter. FavoritesCounter should be created when the question is added to favorites for the first time. Consider a use case when two users tries to add a question to favorites simultaneously - this will cause EntityExistsException when entityManager.persist(counter) is called for the second user. But the code below doesn't work, because when EntityExistsException is thrown, container marks transaction as rollback only and attempt to return getFavoritesCounter(question) fails with javax.resource.ResourceException: Transaction is not active @Stateless public class FavoritesServiceBean implements FavoritesService { ... public void addToFavorites(Question question) { FavoritesCounter counter = getCounter(question); if (counter == null) { counter = createCounter(question); } //increase counter } private FavoritesCounter createCounter(Question question) { try { FavoritesCounter counter = new FavoritesCounter(); counter.setQuestion(question); entityManager.persist(counter); entityManager.flush(); return counter; } catch (EntityExistsException e) { return getFavoritesCounter(question); } } private FavoritesCounter getFavoritesCounter(Question question) { Query counterQuery = entityManager.createQery("SELECT counter FROM FavoritesCounter counter WHERE counter.question = :question"); counterQuery.setParameter("question", question); List<FavoritesCounter> result = counterQuery.getResultList(); if (result.isEmpty()) return null; return result.get(0); } } Question @Entity public class Question implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; //getter and setter for id } FavoritesCounter @Entity public class FavoritesCounter implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; @OneToOne @Column(unique = true) private Question question; //getter and setter } What is the best way to handle such a situation - return already created entity after EntityExistsException?

  • Best practices for class-mapping with SoapClient

    - by Foofy
    Using SoapClient's class mapping feature and it's pretty sweet. Unfortunately the SOAP service we're using has a bunch of read-only properties on some of the objects and will throw faults if the properties are passed back as anything but null. Need to filter out the properties before they're used in the SOAP call and am looking for advice on the best way to do it. So far the options are: Stick to a convention where I use getter and setter functions to manipulate the properties, and use property overloading to filter method access since only SoapClient would be doing that. E.g. developers would access properties like this: $obj->getAccountNumber() SoapClient would access properties like this: $obj->accountNumber I don't like this because the properties are still exposed and things could go wrong if developers don't stick to convention. Have a wrapper for SoapClient that sets a public property the mapped objects can check to see if the property is being accessed by SoapClient. I already have a wrapper that assigns a reference to itself to all the mapped objects. class SoapClientWrapper { public function __soapCall($method, $args) { $this->setSoapMode(true); $this->_soapClient->__soapCall($method, $args); $this->setSoapMode(false); } } class Invoice { function __get($val) { if($this->_soapClient->getSoapMode()) { return null; } else { return $this->$val; } } } This works but it doesn't feel right and seems a bit clunky. Do the mapping manually, and don't use SoapClient's mapping features. I'd just have a function on all the mapped objects that returns the safe-to-send properties. Also, nobody would have access to properties they shouldn't since I could enforce getters and setters. A lot more work, though.

  • .NET Remoting memory leak?

    - by PrimeTSS
    I have a Remoting Class as a Singleton <configuration> <system.runtime.remoting> <application> <service> <wellknown mode="Singleton" type="PTSSLinkClasses.PTSSLinkClientDesktopRemotable, PTSSLinkClasses" objectUri="PTSSLinkDesktop" /> </service> <channels> <channel ref="http" port="8901"/> </channels> </application> </system.runtime.remoting> </configuration> Its created within a "server" Service. Another client service consumes this remote object. The client is calling the remote object every .5 second using a timer (polling) (for testing) If the server service is stopped, so the remote object is not available, memory useage for the client service keeps increasing...... I have overwritten InitialLifetimeService to return a null public override Object InitializeLifetimeService() { return null; } If a remote object is not available does .net queue all the call requests to this object??? untill all the memory is consumed? How can I dected if the remote object is not available and stop trying to call the remote method?

  • Getting a gestureoverlayview

    - by Codejoy
    I have been using some nice tutorials on drawing graphics on my android. I wanted to also add in the cool gesture demo found here: http://developer.android.com/resources/articles/gestures.html That takes these lines of code: GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures); gestures.addOnGesturePerformedListener(this); This is fine and dandy yet I realize in my demo i'm trying to build using code from "Playing with Graphics in Android". The demos make sense, everything makes sense but I found out by using: setContentView(new Panel(this)); as is required by the Playing With Graphics tutorials, then the findViewById seems to no longer be valid and returns null. At first I was about to post a stupider question as to why this is happening, a quick test of playing with the setContentView made me realize the cause of findViewById returning null, I just do not know how to remedy this issue. Whats the key I am missing here? I realize that the new Panel is doinking some reference up but I am not sure how to make the connection here. THe: R.id.gestures is defined right int he main.xml as: (just like the tutorial) Thanks, Shane p.s. im new here be gentle.

  • JACOB (Java/COM/ActiveX) - How to troubleshoot event handling?

    - by Youval Bronicki
    I'm trying to use JACOB to interact with a COM object. I was able to invoke an initialization method on the object (and to get its properties), but am not getting any events back. The code is quoted below. I have a sample HTML+Javascript page (running in IE) that successfully receives events from the same object. I'm considering the following options, but would appreciate any concrete troubleshooting ideas ... Send my Java program to the team who developed the COM object, and have them look for anything suspicious on their side (does the object have a way on knowing whether there's a client listening to its events, and whether they were successfully delivered?) Get into the native parts of JACOB and try to debug on that side. That's a little scary given that my C++ is rusty and that I've never programmed for Windows. public static void main(String[] args) { try { ActiveXComponent c = new ActiveXComponent( "CLSID:{********-****-****-****-************}"); // My object's clsid if (c != null) { System.out.println("Version:"+c.getProperty("Version")); InvocationProxy proxy = new InvocationProxy() { @Override public Variant invoke(String methodName, Variant[] targetParameters) { System.out.println("*** Event ***: " + methodName); return null; } }; DispatchEvents de = new DispatchEvents((Dispatch) c.getObject(), proxy); c.invoke("Init", new Variant[] { new Variant(10), //param1 new Variant(2), //param2 }); System.out.println("Wating for events ..."); Thread.sleep(60000); // 60 seconds is long enough System.out.println("Cleaning up ..."); c.safeRelease(); } } catch (Exception e) { e.printStackTrace(); } finally { ComThread.Release(); } }
