  • getJSON not working if the mvc model view controller has a parameter

    - by Paul
    I'm having an issue with a callback. I'm not even getting an error in Firebug. If I alert before and after the getjson call both alerts show but the getjson call doesn't fire. public ActionResult TestPage() { return View(); } public ActionResult LoadMapLonLats(int mapId) { //some code return Json(_myMaps); } $("#Search").click(function() { $.getJSON("LoadMapLonLats", { mapId: 73 }, loadDbMap); }); function loadDbMap(maps) { alert('m'); $.each(maps, function(i) { alert(maps[i]); }); } As long as I leave TestPage without a parameter is works. If I add a parameter to TestPage(int id) then the call back to LoadMapLonLats doesn't work. Seems odd. Of course TestPage is the page I'm loading so I need to do some work here before rendering the page. Not sure why adding a parameter to the view would break the callback to another function. //this breaks he callback to LoadMapLonLats public ActionResult TestPage(int id) { return View(); } Any ideas? Seems like this may be related, if not sorry I can post a new thread.

  • Algorithm for dynamic combinations

    - by sOltan
    My code has a list called INPUTS, that contains a dynamic number of lists, let's call them A, B, C, .. N. These lists contain a dynamic number of Events I would like to call a function with each combination of Events. To illustrate with an example: INPUTS: A(0,1,2), B(0,1), C(0,1,2,3) I need to call my function this many times for each combination (the input count is dynamic, in this example it is three parameter, but it can be more or less) function(A[0],B[0],C[0]) function(A[0],B[1],C[0]) function(A[0],B[0],C[1]) function(A[0],B[1],C[1]) function(A[0],B[0],C[2]) function(A[0],B[1],C[2]) function(A[0],B[0],C[3]) function(A[0],B[1],C[3]) function(A[1],B[0],C[0]) function(A[1],B[1],C[0]) function(A[1],B[0],C[1]) function(A[1],B[1],C[1]) function(A[1],B[0],C[2]) function(A[1],B[1],C[2]) function(A[1],B[0],C[3]) function(A[1],B[1],C[3]) function(A[2],B[0],C[0]) function(A[2],B[1],C[0]) function(A[2],B[0],C[1]) function(A[2],B[1],C[1]) function(A[2],B[0],C[2]) function(A[2],B[1],C[2]) function(A[2],B[0],C[3]) function(A[2],B[1],C[3]) This is what I have thought of so far: My approach so far is to build a list of combinations. The element combination is itself a list of "index" to the input arrays A, B and C. For our example: my list iCOMBINATIONS contains the following iCOMBO lists (0,0,0) (0,1,0) (0,0,1) (0,1,1) (0,0,2) (0,1,2) (0,0,3) (0,1,3) (1,0,0) (1,1,0) (1,0,1) (1,1,1) (1,0,2) (1,1,2) (1,0,3) (1,1,3) (2,0,0) (2,1,0) (2,0,1) (2,1,1) (2,0,2) (2,1,2) (2,0,3) (2,1,3) Then I would do this: foreach( iCOMBO in iCOMBINATIONS) { foreach ( P in INPUTS ) { COMBO.Clear() foreach ( i in iCOMBO ) { COMBO.Add( P[ iCOMBO[i] ] ) } function( COMBO ) --- (instead of passing the events separately) } } But I need to find a way to build the list iCOMBINATIONS for any given number of INPUTS and their events. Any ideas? Is there actually a better algorithm than this? any pseudo code to help me with will be great. C# (or VB) Thank You

  • QT: trouble with qobject_cast

    - by weevilo
    I have derived QGraphicsItem and QGraphicsScene classes. I want the items to be able to call scene() and get a derviedGraphicsItem * instead of a QGraphicsItem *, so I reimplemented QGraphicsScene::itemAt to return a derived pointer. DerivedItem* DerivedScene::itemAt( const QPointF &position, const QTransform &dt ) const { return qobject_cast< DerivedItem * >( QGraphicsScene::itemAt(position, dt) ); } I get the following error (Qt 4.6, GCC 4.4.3 on Ubuntut 10.4) scene.cpp: In member function ‘DerivedItem* DerivedScene::itemAt(qreal, qreal, const QTransform&) const’: scene.cpp:28: error: no matching function for call to ‘qobject_cast(QGraphicsItem*)’ I then noticed QGraphicsItem doesn't inherit QObject, so I made my derived QGraphicsItem class have multiple inheritance from QObject and QGraphicsItem, and after adding the Q_OBJECT macro and rebuilding the project I get the same error. Am I going about this the wrong way? I know it's supposed to be bad design to try to cast a parent class as a child, but in this case it seems like what I want, since my derived item class has new functionality and its objects need a way to call that new functionality on items around themselves, and asking the items scene object with itemAt() seems like the best way - but I need itemAt() to return a pointer of the right type. I can get around this by having the derived items cast the QGraphicsItem * returned by QGraphicsScene::itemAt() using dynamic_cast, but I don't really understand why that works and not qobject_cast, or the benefits or disadvantages to using dynamic_cast vs. qobject_cast.

  • Windows 7 - Enable Network DTC Access

    - by Russ Clark
    I have a Visual Studio 2010 Windows Forms application in which I start a transaction using the TransactionScope class. I then Receive a message from a Sql Server Broker Services message queue, which works fine. I next try to call a stored procedure from the same database with a call to my data access layer which is a Visual Studio dataset (xsd file). When I make this second call to the database I get the following error message: The MSDTC transaction manager was unable to pull the transaction from the source transaction manager due to communication problems. Possible causes are: a firewall is present and it doesn't have an exception for the MSDTC process, the two machines cannot find each other by their NetBIOS names, or the support for network transactions is not enabled for one of the two transaction managers. (Exception from HRESULT: 0x8004D02B). I've seen several posts on the web that talk about Enabling DTC access through dcomcnfg.exe, and allowing DTC to communicate through Windows Firewall. I've done those things, and am still having this problem. I know our remote database server is setup to Enable DTC access, because we are using similar transactions in other projects built with Visual Studio 2008 on Windows XP and Vista. I think there is something specific about Windows 7 and Visual Studio 2010 causing this problem, but haven't been able to find out what it is. Can anyone help with this problem?

  • jQuery autocomplete - update options on dynamically created elements

    - by Ian Robinson
    Background The user enters values into multiple inputs on the page. Think of entering a list of widgets for sale. The user would select the type of a widget from a drop down. Then enter the name of the Widget vendor, and then the actual name of the widget. These UI elements would all appear as one row. The user is able to click an "add another widget" link and a new row is created. The two input elements have autocomplete functionality attached to them using the DevBridge jQuery plugin. It suggests the name of the vendor and the name of the widget. I have recently wired up the logic to filter the name of the widget based on the name of the vendor you entered. This means setting the (custom) vendorName parameter when attaching the autocomplete plugin so it can be passed to the server side to retrieve the widget names for that vendor that match the name the user entered. To achieve this functionality I'm dynamically attaching the autocomplete functionality to the second element (the widget name text box) when it receives focus. Here is an example: $('.autocomplete-widget').live('focus', function () { $(this).autocomplete({ serviceUrl: '/something.ashx', params: { type: 'widget', vendorName: $(this).parent().prev().find('.autocomplete-vendor').val()} }); }); Problem At first glance, this looks to function quite well. However I started noticing some inconsistencies, and upon inspection, I found out that the call to the server is actually happening several times in some cases. Each time the widget name input element receives focus the autocomplete functionality is attached. And what I'm seeing is that the call to the server is made in proportion to how many times the input element has gained focus. I'd like to avoid making the call more than once, but retain the ability to attach (or update) the autocomplete functionality "on focus". I've tried to use the autocomplete 'setOptions' method but have only been able to get it to work with the static elements, not the dynamically created elements. Question Is there a way I can clear out the autocomplete functionality before I attach another one?

  • Using oauth2_access_token to get connections in linkedIn

    - by Pedro
    I'm trying to get the connections in linkedIn using their API, but when I try to retrieve the connections I get a 401 unauthorized error. in the official documentation says You must use an access token to make an authenticated call on behalf of a user Make the API calls You can now use this access_token to make API calls on behalf of this user by appending "oauth2_access_token=access_token" at the end of the API call that you wish to make. The API call that I'm trying to do is the following Error -- http://api.linkedin.com/v1/people/~/connections:(id,headline,first-name,last-name)?format=json&oauth2_access_token=access_token I have tried to do it with the following endpoint without any problems. OK -- https://api.linkedin.com/v1/people/~:(id,first-name,last-name,formatted-name,date-of-birth,industry,email-address,location,headline,picture-urls::(original))?format=json&oauth2_access_token=access_token this list of endpoints for the connections API are described here http://developer.linkedin.com/documents/connections-api I just copied and pasted one endpoint from there, so the question is what's the problem with the endpoint for getting the connections? what am I missing? EDIT: for the preAuth Url I'm using https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=ConsumerKey&scope=r_fullprofile%20r_emailaddress%20r_network&state&state=NewGuid&redirect_uri=Encoded_Url https://www.linkedin.com/uas/oauth2/accessToken?grant_type=authorization_code&code=QueryString_Code&redirect_uri=EncodedCallback&client_id=ConsummerKey&client_secret=ConsumerSecret please find attached the login screen requesting the permissions EDIT2: Switched to https and worked like a charm!

  • how does scrolling in android listview work?

    - by gartenkralleb
    hi, i have an android-app with a listview in an activity. the listview has, if i call it so, three data states. no data loaded from inet - only one dummy item is visible, saying that data is loading data is loaded and shown in list one listitem is clicked and now shows more information for this listitem (so it is increased in its height) on every state change (1 - 2, 2 - 3) i call notifyDataSetChanged() on this ListAdapater. this causes the listview to scroll down to the last item. this is ugly in the first transition and even more ugly in the second because the clicked list item is now out of focus. as i can see, this happens with a google g1 with android 1.6. a htc touch with the same sdk acts like desired (i try to figure it out with some more devices). to avoid this i tried to read out getScrollY() and set this value back. but this returns 0. the reason for this return value i already found on stackoverflow in other qutestions. does anyone else comes along with my problem so far? why does the listview scrolls to the last item? it was mentioned, that listview does keep track on the scroll position. but it seems that it does not in my case. or may i call the wrong refresh method? is notifyDataSetChanged the correct one?

  • Serializing java objects with respect to xml schema loaded at runtime

    - by kohomologie
    I call an XML document three-layered if its structure is laid out as following: the root element contains some container elements (I'll call them entities), each of them has some simpleType elements inside (I'll call them properties). Something like that: <data> <spaceship> <number>1024</number> <name>KTHX</name> </spaceship> <spaceship> <number>1624</number> <name>LEXX</name> </spaceship> <knife> <length>10</length> </knife> </data> where spaceship is an entity, and number is a property. My problem is stated below: Given schema: an arbitrary xsd file describing a three-layered document, loaded at runtime. xmlDocument: an xml document conforming to the schema. Create A Map<String, Map <String, Object>> containing data from the xmlDocument, where first key corresponds to entity, second key correponds to this entity's property, and the value corresponds to this property's value, after casting it to a proper java type (for example, if the schema sets the property value to be xs:int, then it should be cast to Integer). What is the easiest way to achieve this result with existing libraries? P. S. JAXB is not really an option here. The schema might be arbitrary and unknown at compile-time. Also I wish to avoid an excessive use of reflection (associated with converting the beans to maps). I'm looking for something that would allow me to make the typecasts while xml is being parsed.

  • again about JPA/Hibernate bulk(batch) insert

    - by abovesun
    Here is simple example I've created after reading several topics about jpa bulk inserts, I have 2 persistent objects User, and Site. One user could have many site, so we have one to many relations here. Suppose I want to create user and create/link several sites to user account. Here is how code looks like, considering my willing to use bulk insert for Site objects. User user = new User("John Doe"); user.getSites().add(new Site("google.com", user)); user.getSites().add(new Site("yahoo.com", user)); EntityTransaction tx = entityManager.getTransaction(); tx.begin(); entityManager.persist(user); tx.commit(); But when I run this code (I'm using hibernate as jpa implementation provider) I see following sql output: Hibernate: insert into User (id, name) values (null, ?) Hibernate: call identity() Hibernate: insert into Site (id, url, user_id) values (null, ?, ?) Hibernate: call identity() Hibernate: insert into Site (id, url, user_id) values (null, ?, ?) Hibernate: call identity() So, I means "real" bulk insert not works or I am confused? Here is source code for this example project, this is maven project so you have only download and run mvn install to check output.

  • Thread-safe data structures

    - by Inso Reiges
    Hello, I have to design a data structure that is to be used in a multi-threaded environment. The basic API is simple: insert element, remove element, retrieve element, check that element exists. The structure's implementation uses implicit locking to guarantee the atomicity of a single API call. After i implemented this it became apparent, that what i really need is atomicity across several API calls. For example if a caller needs to check the existence of an element before trying to insert it he can't do that atomically even if each single API call is atomic: if(!data_structure.exists(element)) { data_structure.insert(element); } The example is somewhat awkward, but the basic point is that we can't trust the result of exists call anymore after we return from atomic context (the generated assembly clearly shows a minor chance of context switch between the two calls). What i currently have in mind to solve this is exposing the lock through the data structure's public API. This way clients will have to explicitly lock things, but at least they won't have to create their own locks. Is there a better commonly-known solution to these kinds of problems? And as long as we're at it, can you advise some good literature on thread-safe design? Thank you.

  • Very strange iSeries Provider behavior

    - by AJ
    We've been given a "stored procedure" from our RPG folks that returns six data tables. Attempting to call it from .NET (C#, 3.5) using the iSeries Provider for .NET (tried using both V5R4 and V6R1), we are seeing different results based on how we call the stored proc. Here's way that we'd prefer to do it: using (var dbConnection = new iDB2Connection("connectionString")) { dbConnection.Open(); using(var cmd = dbConnection.CreateCommand()) { cmd.CommandType = CommandType.StoredProcedure; cmd.CommandText = "StoredProcName"; cmd.Parameters.Add(new iDB2Parameter("InParm1", iDB2DbType.Varchar).Value = thing; var ds = new DataSet(); var da = new iDB2DataAdapter(cmd); da.Fill(ds); } } Doing it this way, we get FIVE tables back in the result set. However, if we do this: cmd.CommandType = CommandType.Text; cmd.CommandText = "CALL StoredProcName('" + thing + "')"; We get back the expected SIX tables. I realize that there aren't many of us sorry .NET-to-DB2 folks out here, but I'm hoping someone has seen this before. TIA.

  • feedparser - various errors

    - by Eiriks
    I need feedparser (se http://www.feedparser.org) for a project, and want to keep third party modules in a separate folder. I did this by adding a folder to my python path, and putting relevant modules there, among them feedparser. This first attempt to import feedparser resulted in import feedparser Traceback (most recent call last): File "", line 1, in File "/home/users/me/modules/feedparser.py", line 1 ed socket timeout; added support for chardet library ^ SyntaxError: invalid syntax I found the text "socket timeout; added..." in the comments at the bottom of the file, removed these comments, and tried again: import feedparser Traceback (most recent call last): File "", line 1, in File "/home/users/me/modules/feedparser.py", line 1 = [(key, value) for key, value in attrs if key in self.acceptable_attributes] ^ IndentationError: unexpected indent Ok, so some indent error. I made sure the indent in the function in question where ok (moved some line breaks down to no-indent). And tried again: import feedparser Traceback (most recent call last): File "", line 1, in File "/home/users/me/modules/feedparser.py", line 1 , value) for key, value in attrs if key in self.acceptable_attributes] ^ SyntaxError: invalid syntax As much I google, I cannot find anything wrong with the syntax: def unknown_starttag(self, tag, attrs): if not tag in self.acceptable_elements: if tag in self.unacceptable_elements_with_end_tag: self.unacceptablestack += 1 return attrs = self.normalize_attrs(attrs) attrs = [(key, value) for key, value in attrs if key in self.acceptable_attributes] _BaseHTMLProcessor.unknown_starttag(self, tag, attrs) Now what? Is my approach all wrong? Why do I keep producing these errors in a module that seems so well tested and trusted?

  • Twitpic API from iPhone - pic posted but no URL returned?

    - by Jamie Badman
    This is a weird one... With the help of people here, I've got my iPhone app posting to TwitPic successfully - and when I first got it working, I could see an XML result being returned too... But for some reason over the past two days, the API call seems to succeed - the pic appears on TwitPic - but... the response seems to be empty... Anyone have any ideas? Seen anything similar? The code I use to invoke the API call is: ASIFormDataRequest *request = [[[ASIFormDataRequest alloc] initWithURL:url] autorelease]; [request setData:twitpicImage forKey:@"media"]; [request setPostValue:username forKey:@"username"]; [request setPostValue:password forKey:@"password"]; // Initiate the WebService request [request start]; // Need to find out how I can access the result from this call... /* Result structure should be: <?xml version="1.0" encoding="UTF-8"?> <rsp stat="ok"> <mediaid>abc123</mediaid> <mediaurl>http://twitpic.com/abc123</mediaurl> </rsp> */ // Check for errors if ([[request responseHeaders] objectForKey:@"stat"] != @"ok"){ UIAlertView *errorAlert = [[UIAlertView alloc] initWithTitle:@"TwitPic Submission" message:[[request responseHeaders] objectForKey:@"mediaurl"] delegate:nil cancelButtonTitle:@"OK!" otherButtonTitles:nil]; [errorAlert show]; [errorAlert release]; } NSString *twitpicURL = [[request responseHeaders] objectForKey:@"mediaurl"]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"TwitPic Submission" message:twitpicURL delegate:nil cancelButtonTitle:@"OK!" otherButtonTitles:nil]; I tried just dumping out [request responseString]... that's empty now also. That WAS showing a response, for sure. As always, any help gratefully received. I'll give back once I'm able! Cheers, Jamie.

  • Can I Specify Strings for MySql Table Values?

    - by afterimagedesign
    I have a MySql table that stores the users state and city from a list of states and cities. I specifically coded each state as their two letter shortened version (like WA for Washington and CA for California) and every city has the two letter abbreviation and the city name formated like this: Boulder Colorado would be CO-boulder and Salt Lake City, Utah would be UT-salt-lake-city as to avoid different states with same city name. The PHP inserts the value (UT-salt-lake-city) under the column City, but when I call the variable through PHP, it displays like this: Your location is: UT-salt-lake-city, Utah. To solve this, I've been making this list of variables if ($city == "AL-auburn") { $city = "Auburn"; } else if ($city == "AL-birmingham") { $city = "Birmingham"; } else if ($city == "GA-columbus") { $city = "Columbus"; $state = "Georgia"; } else if ($city == "AL-dothan") { $city = "Dothan"; } else if ($city == "AL-florence") { $city = "Forence"; } else if ($city == "AL-muscle-shoals") { $city = "Muscle Shoals"; } else if ($city == "AL-gadsden-anniston") { $city = "Gadsden Anniston"; } else if ($city == "AL-huntsville") { $city = "Huntsville"; } else if ($city == "AL-decatur") { $city = "Decatur"; } else if ($city == "AL-mobile") { $city = "Mobile"; } else if ($city == "AL-montgomery") { $city = "Montgomery"; } else if ($city == "AL-tuscaloosa") { $city = "Tuscaloosa"; } Is there a way I can shorten this process or at least call it from a separate file so I don't have to copy/paste every time I want to call the location?

  • Slow XML-RPC in Windows 7 with XML-RPC.NET

    - by Emre Sahin
    I'm considering to use XML-RPC.NET to communicate with a Linux XML-RPC server written in Python. I have tried a sample application (MathApp) from Cook Computing's XML-RPC.NET but it took 30 seconds for the app to add two numbers within the same LAN with server. I have also tried to run a simple client written in Python on Windows 7 to call the same server and it responded in 5 seconds. The machine has 4 GB of RAM with comparable processing power so this is not an issue. Then I tried to call the server from a Windows XP system with Java and PHP. Both responses were pretty fast, almost instantly. The server was responding quickly on localhost too, so I don't think the latency arise from server. My googling returned me some problems regarding Windows' use of IPv6 but our call to server does include IPv4 address (not hostname) in the same subnet. Anyways I turned off IPv6 but nothing changed. Are there any more ways to check for possible causes of latency?

  • Cannot access updated Java object from Saxon XSLT processor

    - by chipk
    I am working with an open source version of the Saxon XSLT processor "Saxon 9.0.0.2J from Saxonica" and am trying to make use of the java extensibility for the first time. I am running into an issue I suspect may be a limitation on the open source version, but wanted to check first whether there might be something I am just missing here. From the snippet below, my result is that the final value of $c1 does not change as a result of the call to greg:setTime() - i.e. the $c1 variable within Saxon appears to be unhooked from the underlying Java object and there is no apparent way to access the object as updated by the setTime() call. NOTE that all code in the snippet is tested and working otherwise - i.e. $c1 is properly instantiated by the getInstance() call, $startdate is of the proper format and $d1 is properly instantiated. Thoughts? <xsl:transform ..... xmlns:sql="java:java.sql.Date" xmlns:greg="java:java.util.GregorianCalendar" ..... > .... <xsl:element name="JobExpireDate"> <xsl:variable name="c1" select="greg:getInstance()" /> <xsl:variable name="d1" select="sql:valueOf($startdate)" /> <xsl:variable name="void" select="greg:setTime($c1,$d1)" /> <xsl:value-of select="$c1" /> </xsl:element>

  • Java SwingWorker still uses 98% CPU after it's done.

    - by RemiX
    I am new to the Java SwingWorker class, but I'm trying to get it to do some stuff in the background. That part works already, but now, when it is finished, the Windows Task Manager still shows that 70-98% of the CPU is still being used. Before I hit the 'Start' button it is only 3-15% and after I close the program it returns to those values. But what is still happening when the SwingWorker already reported being done?? I'll give you a simplified version of my code: I have this StereoProcessor extending SwingWorker, with doInBackground(): yLoop for(some values y) { for(some values x) { if(isCancelled()) break yLoop; else { setProgress(to some value); // do some non-SingWorker-related stuff } } } return returnValue; I call to this process through another code: stereoProcessor.addPropertyChangeListener(new PropertyChangeListener() { public void propertyChange(PropertyChangeEvent evt) { if(evt.getPropertyName().equals("state")) if(evt.getNewValue().equals(StereoProcessor.StateValue.DONE) { // do stuff } } } }); stereoProcessor.computeSomething(); // this method calls execute() That's about it, so I don't understand what it keeps doing. I tried putting some System.outs in the code in different places, but all stopped printing after a while. Does anyone know what's going on? Edit: I noticed the CPU also keeps running after a simple call to a method in StereoProcessor that doesn't even call execute()...

  • PInvoke Unbalances the stack

    - by Giawa
    Good afternoon, I have been working on a dll that can use CORBA to communicate to an application that is network aware. The code works fine if I run it as a C++ console application. However, I have gotten stuck on exporting the methods as a dll. The methods seems to export fine, and if I call a method with no parameters then it works as expected. I'm hung up on passing a C# string to a C++ method. My C++ method header looks like this: bool __declspec(dllexport) SpiceStart(char* installPath) My C# DLL import code is as follows: [DllImportAttribute("SchemSipc.dll", CharSet=CharSet.Ansi)] private static extern bool SpiceStart(string installPath); I call the method like so: bool success = SpiceStart(@"c:\sedatools"); The call to SpiceStart throws the exception "PInvokeStackImbalance", which "is likely because the managed PInvoke signature does not match the unmanaged target signature." Does anyone have any suggestions? If I remove the char* and string from the parameters, then the method runs just fine. However, I'd like to be able to pass the installation path of the application to the dll from C#. Thanks in advance, Giawa

  • ASP.NET 2.0 app runs on Win 2003 in IIS 5 isolation mode but not in (default) IIS 6 mode

    - by Tex
    The app uses DLLImport to call a legacy unmanaged dll. Let's call this dll Unmanaged.dll for the sake of this question. Unmanaged.dll has dependencies on 5 other legacy dll's. All of the legacy dll's are placed in the WebApp/bin/ directory of my ASP.NET application. When IIS is running in 5.0 isolation mode, the app works fine - calls to the legacy dll are processed without error. When IIS is running in the default 6.0 mode, the app is able to initiate the Unmanaged.dll (InitMe()), but dies during a later call to it (ProcessString()). I'm pulling my hair out here. I've moved the unmanaged dll's to various locations, tried all kinds of security settings and searched long and hard for a solution. Help! Sample code: [DllImport("Unmanaged.dll", EntryPoint="initME", CharSet=System.Runtime.InteropServices.CharSet.Ansi, CallingConvention=CallingConvention.Cdecl)] internal static extern int InitME(); //Calls to InitMe work fine - Unmanaged.dll initiates and writes some entries in a dedicated log file [DllImport("Unmanaged.dll", EntryPoint="processString", CharSet=System.Runtime.InteropServices.CharSet.Ansi, CallingConvention=CallingConvention.Cdecl)] internal static extern int ProcessString(string inStream, int inLen, StringBuilder outStream, ref int outLen, int maxLen); //Calls to ProcessString cause the app to crash, without leaving much of a trace that I can find so far

  • TimoutException occurs over a network but not locally

    - by Gibsnag
    I have a program with three WCF services and when I run them locally (i.e: Server and Clients are all on localhost) everything works. However when I test them across a network I get a TimoutException on two services but not the other. I've disabled the firewalls on all the machines involved in the test. I can both ping the server and access the wsdl "You have created a service" webpage from the client The service that works uses a BasicHttpBinding with streaming and the two which don't work use WSDualHttpBinding. The Services that use WSDualHttpBinding both have CallbackContracts. I apologise for the vagueness of this question but I'm not really sure what code to include or where to even start looking for the solution to this. Non-working bindings: public static Binding CreateHTTPBinding() { var binding = new WSDualHttpBinding(); binding.MessageEncoding = WSMessageEncoding.Mtom; binding.MaxBufferPoolSize = 2147483647; binding.MaxReceivedMessageSize = 2147483647; binding.Security.Mode = WSDualHttpSecurityMode.None; return binding; } Exception Stack Trace: Unhandled Exception: System.TimeoutException: The open operation did not complete within the allotted timeout of 00:01:00.

  • Using a4j:support 's onchange event with h:selectOneMenu

    - by user339637
    <h:selectOneMenu id="selectOneMenu" value="#{Bean1.val1}" > <f:selectItems value="#{Bean1.selectItems}"/> <a4j:support event="onchange" action="#{Bean1.onSelectOneMenuChange}" reRender="textbox1 , textbox2 , textbox3, textbox4" /> </h:selectOneMenu> <h:inputText id="textbox1" value="#{Bean1.textbox1}"> </h:inputText> <h:inputText id="textbox2" value="#{Bean1.textbox2}"> </h:inputText> <h:inputText id="textbox3" value="#{Bean1.textbox3}"> </h:inputText> <h:inputText id="textbox4" value="#{Bean1.textbox4}"> </h:inputText> Bean1.onSelectOneMenuChange() will change the value of Bean1.textbox1 , Bean1.textbox2,Bean1.textbox3 and Bean1.textbox4 depending on the value selected (Bean1.val1) .Sometimes , it will change all the textbox value and sometimes it will only changes some textbox value. When users change the value in the "selectOneMenu" drop down list control , the JSF framework will not call the update model values phase but call the Bean1.onSelectOneMenuChange() directly. After that , the all the textbox are reRender. Because the update model values phase is not called , the values entered by the user is never set the the Bean1 and the original value is shown in the textbox after reRender . So I want to ask: How can I manually call the update model values phase inside Bean1.onSelectOneMenuChange() ?How can I get the value input input by the users inside Bean1.onSelectOneMenuChange() and set it to the corresponding fields of the Bean1 ? 2.Another approach is that only reRender those textbox whose values are updated inside the Bean1.onSelectOneMenuChange() .However , there are many cases . For example , a value will change all the textbox value and a values may only change some textbox value.How can I reRender conditionally ? What method is more prefer for maintainability?

  • [MFC] I can't re-parent a window

    - by John
    Following on from this question, now I have a clearer picture what's going on... I have a MFC application with no main window, which exposes an API to create dialogs. When I call some of these methods repeatedly, the dialogs created are parented to each other instead of all being parented to the desktop... I have no idea why. But anyway even after creation, I am unable to change the parent back to NULL or CWnd::GetDesktopWindow()... if I call SetParent followed by GetParent, nothing has changed. So apart from the really weird question of why Windows is magically parenting each dialog to the last one created, is there anything I'm missing to be able to set these windows as children of the desktop? UPDATED: I have found the reason for all this, but not the solution. From my dialog constructor, we end up in: BOOL CDialog::CreateIndirect(LPCDLGTEMPLATE lpDialogTemplate, CWnd* pParentWnd, void* lpDialogInit, HINSTANCE hInst) { ASSERT(lpDialogTemplate != NULL); if (pParentWnd == NULL) pParentWnd = AfxGetMainWnd(); m_lpDialogInit = lpDialogInit; return CreateDlgIndirect(lpDialogTemplate, pParentWnd, hInst); } Note: if (pParentWnd == NULL)pParentWnd = AfxGetMainWnd(); The call-stack from my dialog constructor looks like this: mfc80d.dll!CDialog::CreateIndirect(const DLGTEMPLATE * lpDialogTemplate=0x005931a8, CWnd * pParentWnd=0x00000000, void * lpDialogInit=0x00000000, HINSTANCE__ * hInst=0x00400000) mfc80d.dll!CDialog::CreateIndirect(void * hDialogTemplate=0x005931a8, CWnd * pParentWnd=0x00000000, HINSTANCE__ * hInst=0x00400000) mfc80d.dll!CDialog::Create(const char * lpszTemplateName=0x0000009d, CWnd * pParentWnd=0x00000000) mfc80d.dll!CDialog::Create(unsigned int nIDTemplate=157, CWnd * pParentWnd=0x00000000) MyApp.exe!CMyDlg::CMyDlg(CWnd * pParent=0x00000000)
