  • javascript new Date(0) class shows 16 hours?

    - by Jonah
    interval = new Date(0); return interval.getHours(); The above returns 16. I expect it to return 0. Any pointers? getMinutes() and getSeconds() return zero as expected. Thanks! I am trying to make a timer: function Timer(onUpdate) { this.initialTime = 0; this.timeStart = null; this.onUpdate = onUpdate this.getTotalTime = function() { timeEnd = new Date(); diff = timeEnd.getTime() - this.timeStart.getTime(); return diff + this.initialTime; }; this.formatTime = function() { interval = new Date(this.getTotalTime()); return this.zeroPad(interval.getHours(), 2) + ":" + this.zeroPad(interval.getMinutes(),2) + ":" + this.zeroPad(interval.getSeconds(),2); }; this.start = function() { this.timeStart = new Date(); this.onUpdate(this.formatTime()); var timerInstance = this; setTimeout(function() { timerInstance.updateTime(); }, 1000); }; this.updateTime = function() { this.onUpdate(this.formatTime()); var timerInstance = this; setTimeout(function() { timerInstance.updateTime(); }, 1000); }; this.zeroPad = function(num,count) { var numZeropad = num + ''; while(numZeropad.length < count) { numZeropad = "0" + numZeropad; } return numZeropad; } } It all works fine except for the 16 hour difference. Any ideas?

  • NSThread shared object issue

    - by Chris Beeson
    Hi, I'm getting an “EXC_BAD_ACCESS” but just can't work out why, any help would be massive - thank you in advance. The user takes a picture and I want to do some processing on it in another thread... - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { ... NSString *uid = [Asset stringWithUUID]; [_imageQueue setObject:img forKey:uid]; [NSThread detachNewThreadSelector:@selector(createAssetAsyncWithImage:) toTarget:self withObject:uid]; } Then the new thread -(void) createAssetAsyncWithImage:(NSString *)uid { NSAutoreleasePool * pool =[[NSAutoreleasePool alloc] init]; if ([_imageQueue objectForKey:uid]) { Asset *asset = [Asset createAssetWithImage:[_imageQueue objectForKey:uid]]; asset.uid = uid; [self performSelectorOnMainThread:@selector(asyncAssetCreated:) withObject:asset waitUntilDone:YES]; } [pool release]; } Which calls +(Asset *)createAssetWithImage:(UIImage *)img { .... UIImage *masterImg = [GraphicSupport createThumbnailFromImage:img pixels:img.size.height/2]; .... return newAsset; } And then this is where I keep getting the BAD_ACCESS +(UIImage *)createThumbnailFromImage:(UIImage *)inImage pixels:(float)pixels{ CGSize size = image.size; CGFloat ratio = 0; if (size.width > size.height) { ratio = pixels / size.width; } else { ratio = pixels / size.height; } CGRect rect = CGRectMake(0.0, 0.0, ratio * size.width, ratio * size.height); UIGraphicsBeginImageContext(rect.size); //NSAssert(image,@"image NULL"); [image drawInRect:rect]; return UIGraphicsGetImageFromCurrentImageContext(); } It's image that is giving me all the complaints... What am I doing wrong?? Many thanks in advance

  • Problem with XElement and XslCompiledTransform

    - by Graham Clark
    I'm having some trouble using a combination of XElement and XslCompiledTransform. I've put the sample code I'm using below. If I get my input XML using the GetXmlDocumentXml() method, it works fine. If I use the GetXElementXml() method instead, I get an InvalidOperationException when calling the Transform method of XslComiledTransform: Token Text in state Start would result in an invalid XML document. Make sure that the ConformanceLevel setting is set to ConformanceLevel.Fragment or ConformanceLevel.Auto if you want to write an XML fragment. The CreateNavigator method on both XElement and XmlDocument returns an XPathNavigator. What extra stuff is XmlDocument doing so this all works, and how can I do the same with XElement? Am I just doing something insane? static void Main(string[] args) { XslCompiledTransform stylesheet = GetStylesheet(); // not shown for brevity IXPathNavigable input = this.GetXElementXml(); using (MemoryStream ms = this.TransformXml(input, stylesheet)) { XmlReader xr = XmlReader.Create(ms); xr.MoveToContent(); } } private MemoryStream TransformXml( IXPathNavigable xml, XslCompiledTransform stylesheet) { MemoryStream transformed = new MemoryStream(); XmlWriter writer = XmlWriter.Create(transformed); stylesheet.Transform(xml, null, writer); transformed.Position = 0; return transformed; } private IXPathNavigable GetXElementXml() { var xml = new XElement("x", new XElement("y", "sds")); return xml.CreateNavigator(); } private IXPathNavigable GetXmlDocumentXml() { var xml = new XmlDocument(); xml.LoadXml("<x><y>sds</y></x>"); return xml.CreateNavigator(); }

  • RhinoMocks Testing callback method

    - by joblot
    Hi All I have a service proxy class that makes asyn call to service operation. I use a callback method to pass results back to my view model. Doing functional testing of view model, I can mock service proxy to ensure methods are called on the proxy, but how can I ensure that callback method is called as well? With RhinoMocks I can test that events are handled and event raise events on the mocked object, but how can I test callbacks? ViewModel: public class MyViewModel { public void GetDataAsync() { // Use DI framework to get the object IMyServiceClient myServiceClient = IoC.Resolve<IMyServiceClient>(); myServiceClient.GetData(GetDataAsyncCallback); } private void GetDataAsyncCallback(Entity entity, ServiceError error) { // do something here... } } ServiceProxy: public class MyService : ClientBase, IMyServiceClient { // Constructor public NertiAdminServiceClient(string endpointConfigurationName, string remoteAddress) : base(endpointConfigurationName, remoteAddress) { } // IMyServiceClient member. public void GetData(Action<Entity, ServiceError> callback) { Channel.BeginGetData(EndGetData, callback); } private void EndGetData(IAsyncResult result) { Action<Entity, ServiceError> callback = result.AsyncState as Action<Entity, ServiceError>; ServiceError error; Entity results = Channel.EndGetData(out error, result); if (callback != null) callback(results, error); } } Thanks

  • How to set the tableview's top using contentinset property while being at the bottom of the table

    - by neha
    Hi all, I'm having a tableview with 20 rows and 250 as their rowheight. While I'm at the bottom of the tableview, I want to shift the tableview upwards by 65px. I tried doing self.tableView.contentInset = UIEdgeInsetsMake(-65.0f, 0.0f, 0.0f, 0.0f); Also self.tableView.contentInset = UIEdgeInsetsMake((4633.0f - 65.0f), 0.0f, 0.0f, 0.0f); where 4633.0f is my contentoffset.y, but with no success. When the last cell is pulled upwards, I'm showing a view below the last cell with an activity indicator on it to depict that more data is getting loaded. I need to keep that view visible for 2 seconds so I want to push the tableview cells up and after that I want to bring the tableview to its original position and reset the view below that. I'm doing this [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.2]; // self.tableView.contentInset = UIEdgeInsetsMake((4633.0f - 65.0f), 0.0f, 0.0f, 0.0f); self.tableView.contentInset = UIEdgeInsetsMake(- 65.0f, 0.0f, 0.0f, 0.0f); [UIView commitAnimations]; and then calling a function to reset it back as self.tableView.contentInset = UIEdgeInsetsMake(0.0f, 0.0f, 0.0f, 0.0f); Can anybody please suggest how to do it? Thanx in advance.

  • GDI RoundRect on Compact Framework: make rounded rectangle's outside transparent.

    - by VansFannel
    Hello! I'm using the RoundRect GDI function to draw a rounded rectangle following this example: .NET CF Custom Control: RoundedGroupBox Because all controls are square, it also draw the corners outside of the rounded rectangle. How can I make this space left outside the rectangle transparent? The OnPaint method is: protected override void OnPaint(PaintEventArgs e) { int outerBrushColor = HelperMethods.ColorToWin32(m_outerColor); int innerBrushColor = HelperMethods.ColorToWin32(this.BackColor); IntPtr hdc = e.Graphics.GetHdc(); try { IntPtr hbrOuter = NativeMethods.CreateSolidBrush(outerBrushColor); IntPtr hOldBrush = NativeMethods.SelectObject(hdc, hbrOuter); NativeMethods.RoundRect(hdc, 0, 0, this.Width, this.Height, m_diametro, m_diametro); IntPtr hbrInner = NativeMethods.CreateSolidBrush(innerBrushColor); NativeMethods.SelectObject(hdc, hbrInner); NativeMethods.RoundRect(hdc, 0, 18, this.Width, this.Height, m_diametro, m_diametro); NativeMethods.SelectObject(hdc, hOldBrush); NativeMethods.DeleteObject(hbrOuter); NativeMethods.DeleteObject(hbrInner); } finally { e.Graphics.ReleaseHdc(hdc); } if (!string.IsNullOrEmpty(m_roundedGroupBoxText)) { Font titleFont = new Font("Tahoma", 9.0F, FontStyle.Bold); Brush titleBrush = new SolidBrush(this.BackColor); try { e.Graphics.DrawString(m_roundedGroupBoxText, titleFont, titleBrush, 14.0F, 2.0F); } finally { titleFont.Dispose(); titleBrush.Dispose(); } } base.OnPaint(e); } An the OnPaintBackground is: protected override void OnPaintBackground(PaintEventArgs e) { if (this.Parent != null) { SolidBrush backBrush = new SolidBrush(this.Parent.BackColor); try { e.Graphics.FillRectangle(backBrush, 0, 0, this.Width, this.Height); } finally { backBrush.Dispose(); } } } Thank you!

  • Sql Query - Selecting rows where user can be both friend and user

    - by Gublooo
    Hey Sorry the title is not very clear. This is a follow up to my earlier question where one of the members helped me with a query. I have a following friends Table Friend friend_id - primary key user_id user_id_friend status The way the table is populated is - when I send a friend request to John - my userID appears in user_id and Johns userID appears in user_id_friend. Now another scenario is say Mike sends me a friend request - in this case mike's userID will appear in user_id and my userID will appear in user_id_friend So to find all my friends - I need to run a query to find where my userID appears in both user_id column as well as user_id_friend column What I am trying to do now is - when I search for user say John - I want all users Johns listed on my site to show up along with the status of whether they are my friend or not and if they are not - then show a "Add Friend" button. Based on the previous post - I got this query which does part of the job - My example user_id is 1: SELECT u.user_id, f.status FROM user u LEFT OUTER JOIN friend f ON f.user_id = u.user_id and f.user_id_friend = 1 where u.name like '%' So this only shows users with whom I am friends where they have sent me request ie my userID appears in user_id_friend. Although I am friends with others (where my userID appears in user_id column) - this query will return that as null To get those I need another query like this SELECT u.user_id, f.status FROM user u LEFT OUTER JOIN friend f ON f.user_id_friend = u.user_id and f.user_id = 1 where u.name like '%' So how do I combine these queries to return 1 set of users and what my friendship status with them is. I hope my question is clear Thanks

  • java Processbuilder - exec a file which is not in path on OS X

    - by Jakob
    Okay i'm trying to make ChucK available in exported Processing sketches, i.e. if i export an app from Processing, the ChucK VM binary will be executed from inside the app. So as a user of said app you don't need to worry about ChucK being in your path at all. Right now i'm generating and executing a bash script file, but this way i don't get any console output from ChucK back into Processing: #!/bin/bash cd "[to where the Chuck executable is located]" ./chuck --kill killall chuck # just to make sure ./chuck chuckScript1.ck cuckScriptn.ck then Process p = Runtime.getRuntime().exec("chmod 777 "+scriptPath); p = Runtime.getRuntime().exec(scriptPath); This works but i want to run ChucK directly from Processing instead, but can't get it to execute: String chuckPath = "[folder in which the chuck executable is located]" ProcessBuilder builder = new ProcessBuilder (chuckPath+"/chuck", "test.ck"); final Process process = builder.start(); InputStream is = process.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); String line; while((line = br.readLine()) != null) println(line); println("done chuckin'! exitValue: " + process.exitValue()); Sorry if this is newbie style :D

  • Cannot get assembly version for footer

    - by Jaxidian
    I'm using the automatic build versioning mentioned in this question (not the selected answer but the answer that uses the [assembly: AssemblyVersion("1.0.*")] technique). I'm doing this in the footer of my Site.Master file in MVC 2. My code for doing this is as follows: <div id="footer"> <a href="emailto:[email protected]">[email protected]</a> - Copyright © 2005-<%= DateTime.Today.Year.ToString() %>, foo LLC. All Rights Reserved. - Version: <%= Assembly.GetEntryAssembly().GetName().Version.ToString() %> </div> The exception I get is a Object reference not set to an instance of an object because GetEntryAssembly() returns NULL. My other options don't work either. GetCallingAssembly() always returns "4.0.0.0" and GetExecutingAssembly() always returns "0.0.0.0". When I go look at my DLLs, everything is versioning as I would expect. But I cannot figure out how to access it to display in my footer!!

  • Getting the CVE ID Property of an update from WSUS API via Powershell

    - by thebitsandthebytes
    I am writing a script in Powershell to get the update information from each computer and correlate the information with another System which identifies updates by CVE ID. I have discovered that there is a "CVEIDs" property for an update in WSUS, which is documented in MSDN, but I have no idea how to access the property. Retrieving the CVE ID from WSUS is the key to this script, so I am hoping someone out there can help! Here is the property that I am having difficulty accessing: IUpdate2::CveIDs Property - http://msdn.microsoft.com/en-us/library/aa386102(VS.85).aspx According to this, the IUnknown::QueryInterface method is needed to interface IUpdate2 -  "http://msdn.microsoft.com/en-us/library/ee917057(PROT.10).aspx" "An IUpdate instance can be retrieved by calling the IUpdateCollection::Item (opnum 8) (section 3.22.4.1) method.  The client can use the IUnknown::QueryInterface method to then obtain an IUpdate2, IUpdate3, IUpdate4, or IUpdate5 interface. Additionally, if the update is a driver, the client can use the IUnknown::QueryInterface method to obtain an IWindowsDriverUpdate, IWindowsDriverUpdate2, IWindowsDriverUpdate3, IWindowsDriverUpdate4, or IWindowsDriverUpdate5 interface. " Here is a skeleton of my code: [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration") | Out-Null  if (!$wsus)  {  Returns an object that implements IUpdateServer  $wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer($server, $false, $port)  }  $computerScope = New-Object Microsoft.UpdateServices.Administration.ComputerTargetScope  $updateScope = New-Object Microsoft.UpdateServices.Administration.UpdateScope  $updateScope.UpdateSources = [Microsoft.UpdateServices.Administration.UpdateSources]::MicrosoftUpdate  $wsusMachines = $wsus.GetComputerTargets($computerScope)  foreach machine in QSUS, write the full domain name $wsusMachines | ForEach-Object {  Write-host $.FullDomainName  $updates = $.GetUpdateInstallationInfoPerUpdate($updateScope)  foreach update for each machine, write the update title, installation state and securitybulletin $updates | ForEach-Object {  $update = $wsus.GetUpdate($.UpdateId) # Returns an object that implements Microsoft.UpdateServices.Administration.IUpdate $updateTitle = $update.Title | Write-Host $updateInstallationState = $.UpdateInstallationState | Write-Host $updateSecurityBulletin = $update.SecurityBulletins | Write-Host  $updateCveIds = $update.CveIDs # ERROR: Property 'CveIDs' belongs to IUpdate2, not IUpdate  }  }

  • Array variable initialization error in Java

    - by trinity
    Hello I am trying to write a Java program that reads an input file consisting of URLs, extracts tokens from these, and keeps track of how many times each token appears in the file. I've written the following code: import java.io.*; import java.net.*; public class Main { static class Tokens { String name; int count; } public static void main(String[] args) { String url_str,host; String htokens[]; URL url; boolean found=false; Tokens t[]; int i,j,k; try { File f=new File("urlfile.txt"); FileReader fr=new FileReader(f); BufferedReader br=new BufferedReader(fr); while((url_str=br.readLine())!=null) { url=new URL(url_str); host=url.getHost(); htokens=host.split("\\.|\\-|\\_|\\~|[0-9]"); for(i=0;i<htokens.length;i++) { if(!htokens[i].isEmpty()) { for(j=0;j<t.length;j++) { if(htokens[i].equals(t[j].name)) { t[j].count++; found=true; } } if(!found) { k=t.length; t[k].name=htokens[i]; t[k].count=1; } } } System.out.println(t.length + "class tokens :"); for(i=0;i<t.length;i++) { System.out.println( "name :"+t[i].name+" frequency :"+t[i].count); } } br.close(); fr.close(); } catch(Exception e) { System.out.println(e); } } } But when I run it, it says: variable t not initialized.. What should I do to set it right?

  • why does Integrated Windows Authentication fail when clients access off the network

    - by Bryan
    My background is not with web applications so this problem is hard for me to explain easily. First I'll try to describe the setup. Client setup:-Only browser that is effected is IE 6-8 (Firefox, chrome, opera, and safari all work fine) -A user will try to access our web application from a company laptop that is not connected to our network. -This machine will be a member of our workgroup and have the company DNS listed as a trusted intranet site. (to which the application in question would be a member) -The security logon mode is set to Automatic Logon only in intranet zone only, and IWA authentication is enabled on the clients browser.Server setup:-Windows server 2003 fp2-The application will first redirect to an Authorization asp page which has anonymous access disabled and IWA enabled in IIS.what should happen is that, since the client is not currently on the network, when this page is called it should prompt the user for network credentials. But with IE, instead of prompting, the user gets a page cannot be displayed error because the IIS manager is denying access to the asp page. If the company DNS is removed from the trusted intranet site list then it prompts correctly but disables single sign on the next time that computer is connected to the network or vpn. My assumption is that since IE uses IWA and the site is listed as an internal site, when no network is found IE just sends nulls to the server attempting to authenticate which is swiftly punted back. Other browsers do not have security zones so when network credentials are not present the server prompts for them. Is there a way to get around this so that our clients can keep the company DNS in the intranet zone but still have the server prompt for credentials when not on the network? Any attempt to allow for anonymous access on the asp page, as far as I know, will cause AUTH_USER to return null and again break SSO. I realize this is slightly rambling so I will do my best to clarify and questions you guys might have. Thanks in advance.

  • How to refactor this Javascript anonymous function?

    - by HeavyWave
    We have this anonymous function in our code, which is part of the jQuery's Ajax object parameters and which uses some variables from the function it is called from. this.invoke = function(method, data, callback, error, bare) { $.ajax({ success: function(res) { if (!callback) return; var result = ""; if (res != null && res.length != 0) var result = JSON2.parse(res); if (bare) { callback(result); return; } for (var property in result) { callback(result[property]); break; } } }); } I have omitted the extra code, but you get the idea. The code works perfectly fine, but it leaks 4 Kbs on each call in IE, so I want to refactor it to turn the anonymous function into a named one, like this.onSuccess = function(res) { .. }. The problem is that this function uses variables from this.invoke(..), so I cannot just take it outside of its body. How do I correctly refactor this code, so that it does not use anonymous functions and parent function variables?

  • Alert Dialog with custom layout failing

    So this is related to a question I asked earlier. I am trying to display an alert using a specified layout. My layout is: And the code to call and show the alert dialog is: Context mContext = getApplicationContext(); AlertDialog.Builder builder = new AlertDialog.Builder(mContext); // use a custom View defined in xml View view = LayoutInflater.from(mContext).inflate(R.layout.sell_dialog, (ViewGroup) findViewById(R.id.layout_root)); builder.setView(view); builder.setPositiveButton(android.R.string.ok, new OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // do whatever you want with the input } }); AlertDialog alertDialog = builder.create(); alertDialog.show(); When I run it I get an error saying: Uncaught handler: thread main exiting due to uncaught exception android.view.WindowManager$NadTokenException: Unable to add window -- token null is not for an application I've looked through the android development site and can't figure it out.

  • Why is Dispatcher.Invoke not triggering UI update?

    - by Brandon
    I am trying to reuse a UserControl and also borrow some logic that keeps track of progress. I'll try and simplify things. MyWindow.xaml includes a MyUserControl. MyUserControl has its own progress indicator (Formatting in progress..., Copying files..., etc.) and I'd like to mirror this progress somewhere in the MyWindow form. But, the user control has some logic I don't quite understand. I've read and read but I still don't understand the Dispatcher. Here's a summary of the logic in the user control that updates the progress. this.Dispatcher.Invoke(DispatcherPriority.Input, (Action)(() => { DAProgressIndicator = InfiniteProgress.AddNewInstanceToControl(StatusGrid, new SolidColorBrush(new Color() { A = 170, R = 128, G = 128, B = 128 }), string.Empty); DAProgressIndicator.Message = MediaCardAdminRes.ActivatingCard; ActivateInProgress = true; })); I thought I'd be smart and add an event to MyUserControl that would be called in the ActivateInProgress property set logic. public bool ActivateInProgress { get { return _activateInProgress; } set { _activateInProgress = value; if (ActivateInProgressHandler != null) { ActivateInProgressHandler(value); } } } I'm setting the ActivateInProgressHandler within the MyWindow constructor to the following method that sets the view model property that is used for the window's own progress indicator. private void SetActivation(bool activateInProgress) { viewModel.ActivationInProgress = activateInProgress; } However, the window's progress indicator never changes. So, I'm convinced that the Dispatcher.Invoke is doing something that I don't understand. If I put a message box inside the SetActivation method, the thread blocks and the window's progress indicator is updated. I understand basic threads but this whole Dispatcher thing is new to me. What am I missing?

  • WPF Datagrid set the column values only when the row is left

    - by Noam
    Hello I have a simple class. When I use it in winforms binding, whenever I change a value of a cell and leave the cell, the property immediately get changed. Using WPF Datagrid, whenever i change a value of a cell, the property gets set only after I leave the row. That is problematic for me. What am I doing wrong? Here is my code: public class MyClass : IEditableObject, INotifyPropertyChanged { string _name, _lastName; public string Name { get { return _name; } set { _name = value; _lastName = value + " xxx"; OnPropertyChanged("LastName"); MessageBox.Show("Test"); } } private void OnPropertyChanged(string p) { var x = new PropertyChangedEventArgs(p); if (PropertyChanged != null) PropertyChanged(this, x); } public string LastName { get { return _lastName; } set { _lastName = value; } } public void BeginEdit() { } public void CancelEdit() { } public void EndEdit() { } public event PropertyChangedEventHandler PropertyChanged; } public class myBindingList : BindingList<MyClass> { public myBindingList() { AllowNew = true; Add(new MyClass { Name = "noam" }); Add(new MyClass { Name = "yael" }); } }

  • Comparing objects with IDispatch to get main frame only (BHO)

    - by shaimagz
    I don't know if anyone familiar with BHO (Browser Helper Object), but an expert in c++ can help me too. In my BHO I want to run the OnDocumentComplete() function only on the main frame - the first container and not all the Iframes inside the current page. (an alternative is to put some code only when this is the main frame). I can't find how to track when is it the main frame that being populated. After searching in google I found out that each frame has "IDispatch* pDisp", and I have to compare it with a pointer to the first one. This is the main function: STDMETHODIMP Browsarity::SetSite(IUnknown* pUnkSite) { if (pUnkSite != NULL) { // Cache the pointer to IWebBrowser2. HRESULT hr = pUnkSite->QueryInterface(IID_IWebBrowser2, (void **)&m_spWebBrowser); if (SUCCEEDED(hr)) { // Register to sink events from DWebBrowserEvents2. hr = DispEventAdvise(m_spWebBrowser); if (SUCCEEDED(hr)) { m_fAdvised = TRUE; } } } else { // Unregister event sink. if (m_fAdvised) { DispEventUnadvise(m_spWebBrowser); m_fAdvised = FALSE; } // Release cached pointers and other resources here. m_spWebBrowser.Release(); } // Call base class implementation. return IObjectWithSiteImpl<Browsarity>::SetSite(pUnkSite); } This is where I want to be aware whether its the main window(frame) or not: void STDMETHODCALLTYPE Browsarity::OnDocumentComplete(IDispatch *pDisp, VARIANT *pvarURL) { // as you can see, this function get the IDispatch *pDisp which is unique to every frame. //some code } I asked this question on Microsoft forum and I got an answer without explaining how to actually implement that: http://social.msdn.microsoft.com/Forums/en-US/ieextensiondevelopment/thread/7c433bfa-30d7-42db-980a-70e62640184c

  • How do I get google protocol buffer messages over a socket connection without disconnecting the clie

    - by Dan
    Hi there, I'm attempting to send a .proto message from an iPhone application to a Java server via a socket connection. However so far I'm running into an issue when it comes to the server receiving the data; it only seems to process it after the client connection has been terminated. This points to me that the data is getting sent, but the server is keeping its inputstream open and waiting for more data. Would anyone know how I might go about solving this? The current code (or at least the relevant parts) is as follows: iPhone: Person *person = [[[[Person builder] setId:1] setName:@"Bob"] build]; RequestWrapper *request = [[[RequestWrapper builder] setPerson:person] build]; NSData *data = [request data]; AsyncSocket *socket = [[AsyncSocket alloc] initWithDelegate:self]; if (![socket connectToHost:@"192.168.0.6" onPort:6666 error:nil]){ [self updateLabel:@"Problem connecting to socket!"]; } else { [self updateLabel:@"Sending data to server..."]; [socket writeData:data withTimeout:-1 tag:0]; [self updateLabel:@"Data sent, disconnecting"]; //[socket disconnect]; } Java: try { RequestWrapper wrapper = RequestWrapper.parseFrom(socket.getInputStream()); Person person = wrapper.getPerson(); if (person != null) { System.out.println("Persons name is " + person.getName()); socket.close(); } On running this, it seems to hang on the line where the RequestWrapper is processing the inputStream. I did try replacing the socket writedata method with [request writeToOutputStream:[socket getCFWriteStream]]; Which I thought might work, however I get an error claiming that the "Protocol message contained an invalid tag (zero)". I'm fairly certain that it doesn't contain an invalid tag as the message works when sending it via the writedata method. Any help on the matter would be greatly appreciated! Cheers! Dan (EDIT: I should mention, I am using the metasyntactic gpb code; and the cocoaasyncsocket implementation)

  • flex and jsf access the same instance of bean

    - by David
    i integrate a flex app in a jsf-icefaces app (in a jspx site with the ice:outputmedia-tag) and want to access the same instance of a bean from flex by remote, that jsf inject. i already connect with blazeds to a java-bean. this bean - like all other beans - get other beans by injection of jsf, but when i access the bean by remote from flex it doesnt hold the injected beans (like localizer and accesmanager, both session scoped) and i can't connect to the jsf session (FacesContext.getCurrentInstance() is null). this is because flex create a new instance of the bean and it’s not the same current instance, that jsf inject, i think. i can connect from flex to the database by create a new entity manager in the java bean, but that's not what i want, because it's again another entity manager...i want persist and get data over the accessmanager-bean. i know exadel fiji and flamingo, but i couldn't work with fiji, because my jsf app include the icefaces components and then it doesn't work with richfaces which fiji needs. and flamingo work only with jboss seam and spring. is it right? i also read about the spring-flex-integration, but the jsf application did not create with spring and i don't want to integrate spring in such a large jsf app. yesterday i read about the FlexFactory interface. this interface i have to implement in my own Factory and set it in the service-config.xml of blazeds as a factory read this. i still implement my own factory but i only get application scoped beans over the servlet context which i get over FlexContext.getServletContext().getAttribute("Bean"); and not session scoped beans... i hope there is a chance to connect throw flex and jsf... thanks!

  • WPF Background Thread Invocation

    - by jeffn825
    Maybe I'm mis-remembering how Winforms works or I'm overcomplicating the hell out of this, but here's my problem. I have a WPF client app application that talks to a server over WCF. The current user may "log out" of the WPF client, which closes all open screens, leaves only the navigation pane, and minimizes the program window. When the user re-maximizes the program window, they are prompted to log in. Simple. But sometimes things happen on background threads - like every 5 minutes the client tries to make a WCF calls that refreshes some cached data. And what if the user is logged out when this 5 minute timer triggers? Well, then the user should be prompted to log back in...and this must of course happen on the UI thread. private static ISecurityContext securityContext; public static ISecurityContext SecurityContext { get { if (securityContext == null) { // Login method shows a window and prompts the user to log in Application.Current.Dispatcher.Invoke((Action)Login); } return securityContext; } } So far so good, right? But what happens when multiple threads hit this spot of code? Well, my first intuition was that since I'm syncrhonizing across the Application.Current.Dispatcher, I should be fine, and whichever thread hit first would be responsible for showing the login form and getting the user logged in... Not the case... Thread 1 will hit the code and call ShowDialog on the login form Thread 2 will also hit the code and will call Login as soon as Thread 1 has called ShowDialog, since calling ShowDialog unblocked Thread 1 (I believe because of the way the WPF message pump works) All I want is a synchronized way of getting the user logged back into the application...what am I missing here? Thanks in advance.

  • android app working on simulator but not on phone

    - by raqz
    i have this app that i developed and it works great on the simulator with no errors what so ever. but the moment i try to run the same on the phone for testing, the app crashes stating filenotfoundexception. it says the file /res/drawable/divider_horizontal.9.png is missing. but actually speaking, i have never referenced that file through my code. i believe its a system/os file that is unavailable. i have a custom list view, i guess its the divider there... could somebody please suggest what is wrong here. i believe this is a similar issue discussed here..but i am unable to make

  • Problem with JSONResult

    - by vikitor
    Hi, I' still newby to this so I'll try to explain what I'm doing. Basically what I want is to load a dropdownlist depending on the value of a previous one, and I want it to load the data and appear when the other one is changed. This is the code I've written in my controller: public ActionResult GetClassesSearch(bool ajax, string phylumID, string kingdom){ IList<TaxClass> lists = null; int _phylumID = int.Parse(phylumID); int _kingdom = int.Parse(kingdom); lists = _taxon.getClassByPhylumSearch(_phylumID, _kingdom); return Json(lists.count); } and this is how I call the method from the javascript function: function loadClasses(_phylum) { var phylum = _phylum.value; $.getJSON("/Suspension/GetClassesSearch/", { ajax: true, phylumID: phylum, kingdom: kingdom }, function(data) { alert(data); alert('no fallo') document.getElementById("pClass").style.display = "block"; document.getElementById("sClass").options[0] = new Option("-select-", "0", true, true); //for (i = 0; i < data.length; i++) { // $('#sClass').addOption(data[i].classID, data[i].className); //} }); } The thing is that just like this it works, I pass the function the number of classes within a selected phylum, and it displays the pclass element, the problem gets when I try to populate the slist with data (which should contain the objects retrieved from the database), because when there is data returned by the database changing return Json(lists) instead of return Json(lists.count) I keep getting the same error: A circular reference was detected while serializing an object of type 'SubSonic.Schema.DatabaseColumn'. I've been going round and round debugging and making tests but I can't make it work, and it is suppossed to be a simple thing, but I'm missing something. I have commented the for loop because I'm not quite sure if that's the way you access the data, because I've not been able to make it work when it finds records. Can anyone help me? Thanks in advance, Victor
