  • not able to Deserialize xml into object

    - by Ravisha
    I am having following peice of code ,where in i am trying to serialize and deserailize object of StringResource class. Please note Resource1.stringXml = its coming from resource file.If i pass strelemet.outerXMl i get the object from Deserialize object ,but if i pass Resource1.stringXml i am getting following exception {"< STRING xmlns='' was not expected."} System.Exception {System.InvalidOperationException} class Program { static void Main(string[] args) { StringResource str = new StringResource(); str.DELETE = "CanDelete"; str.ID= "23342"; XmlElement strelemet = SerializeObjectToXmlNode (str); StringResource strResourceObject = DeSerializeXmlNodeToObject<StringResource>(Resource1.stringXml); Console.ReadLine(); } public static T DeSerializeXmlNodeToObject<T>(string objectNodeOuterXml) { try { TextReader objStringsTextReader = new StringReader(objectNodeOuterXml); XmlSerializer stringResourceSerializer = new XmlSerializer(typeof(T),string.Empty); return (T)stringResourceSerializer.Deserialize(objStringsTextReader); } catch (Exception excep) { return default(T); } } public static XmlElement SerializeObjectToXmlNode(object obj) { using (MemoryStream memoryStream = new MemoryStream()) { try { XmlSerializerNamespaces xmlNameSpace = new XmlSerializerNamespaces(); xmlNameSpace.Add(string.Empty, string.Empty); XmlWriterSettings writerSettings = new XmlWriterSettings(); writerSettings.CloseOutput = false; writerSettings.Encoding = System.Text.Encoding.UTF8; writerSettings.Indent = false; writerSettings.OmitXmlDeclaration = true; XmlWriter writer = XmlWriter.Create(memoryStream, writerSettings); XmlSerializer xmlserializer = new XmlSerializer(obj.GetType()); xmlserializer.Serialize(writer, obj, xmlNameSpace); writer.Close(); memoryStream.Position = 0; XmlDocument serializeObjectDoc = new XmlDocument(); serializeObjectDoc.Load(memoryStream); return serializeObjectDoc.DocumentElement; } catch (Exception excep) { return null; } } } } public class StringResource { [XmlAttribute] public string DELETE; [XmlAttribute] public string ID; } < STRING ID="1" DELETE="True" /

  • EJB3 - @Column(insertable="false") question

    - by WhiteTigerK
    Hi All, I'm building a J2SE application with EJB3 and an Oracle Express Edition DB. My problem is like that - I set an EntityBean in my project which matches a table in the DB. The table contains a column which is not nullable and has a default value. All I want is that when persisting a new data to this table using the EJB, the column's value will get its default value. This is how I set it in the project: //holds user's first name @Basic(optional = true) @Column(name = "FIRST_NAME", insertable = false, updatable = true, nullable = false) private String m_firstName; I also set it in the ORM.XML file: <basic name="firstName"> <column name="FIRST_NAME" insertable="false" updatable="true" nullable="false"/> </basic> But for some reason, when creating a new EntityBean and not setting the first name field, and then trying to persist it, i get the following exception: Exception [TOPLINK-4002] (Oracle TopLink Essentials - 2.1 (Build b60e-fcs (12/23/2008))): oracle.toplink.essentials.exceptions.DatabaseException Internal Exception: java.sql.SQLException: ORA-01400: cannot insert NULL into ("TSDB"."USERS"."FIRST_NAME") Which means that the persistence manager tries to insert the first name field although I told it not to. Am I doing something wrong here ? Thanks!

  • Error Cannot create an Instance of "ObjectName" in Designer when using <UserControl.Resources>

    - by Mike Bynum
    Hi All, I'm tryihg to bind a combobox item source to a static resource. I'm oversimplfying my example so that it's easy to understand what i'm doing. So I have created a class public class A : ObservableCollection<string> { public A() { IKBDomainContext Context = new IKBDomainContext(); Context.Load(Context.GetIBOptionsQuery("2C6C1Q"), p => { foreach (var item in SkinContext.IKBOptions) { this.Add(item); } }, null); } } So the class has a constructor that populates itself using a domaincontext that gets data from a persisted database. I'm only doing reads on this list so dont have to worry about persisting back. in xaml i add a reference to the namespace of this class then I add it as a usercontrol.resources to the page control. <UserControl.Resources> <This:A x:Key="A"/> </UserControl.Resources> and then i use it this staticresource to bind it to my combobox items source.in reality i have to use a datatemplate to display this object properly but i wont add that here. <Combobox ItemsSource="{StaticResource A}"/> Now when I'm in the designer I get the error: Cannot Create an Instance of "A". If i compile and run the code, it runs just fine. This seems to only affect the editing of the xaml page. What am I doing wrong?

  • 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?

  • OrientationEventListener not working properly

    - by nixau
    Hi all, I need to handle orientation changes in my Android application. For this purpose I decided to use OrientationEventListener convenience class. But his callback method is given somewhat strange behavior. My application starts in the portrait mode and then eventually switches to the lanscape one. I have some custom code executing in the callback onOrientationChanged method that provides some additional UI handling logic - it has a few calls to findViewById. What is strange is that when switching back from landscape to portrait mode onOrientationChanged callback is called twice, and what's even worse - the second call is dealing with bad Context - findViewById method starts returning null. These calls are made right from the MainThread @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); listener = new OrientationListener(); } @Override protected void onResume() { super.onResume(); // enabling listening listener.enable(); } @Override protected void onPause() { super.onPause(); // disabling listening listener.disable(); } I've replicated the same behavior with a dummy Activity without any logic except for one that deals with orientation hadling. I initiate orientation switch from the Android 2.2 emulator by pressing Ctrl+F11 What could be wrong? Upd: Inner class that implements OrientationEventListener private class OrientationListener extends OrientationEventListener { public OrientationL() { super(getBaseContext()); } @Override public void onOrientationChanged(int orientation) { toString(); } } }

  • Spikes in Socket Performance

    - by Harun Prasad
    We are facing random spikes in high throughput transaction processing system using sockets for IPC. Below is the setup used for the run: The client opens and closes new connection for every transaction, and there are 4 exchanges between the server and the client. We have disabled the TIME_WAIT, by setting the socket linger (SO_LINGER) option via getsockopt as we thought that the spikes were caused due to the sockets waiting in TIME_WAIT. There is no processing done for the transaction. Only messages are passed. OS used Centos 5.4 The average round trip time is around 3 milli seconds, but some times the round trip time ranges from 100 milli seconds to couple of seconds. Steps used for Execution and Measurement and output Starting the server $ python sockServerLinger.py /dev/null & Starting the client to post 1 million transactions to the server. And logs the time for a transaction in the client.log file. $ python sockClient.py 1000000 client.log Once the execution finishes the following command will show the execution time greater than 100 milliseconds in the format <line_number>:<execution_time>. $ grep -n "0.[1-9]" client.log | less Below is the example code for Server and Client. Server # File: sockServerLinger.py import socket, traceback,time import struct host = '' port = 9999 l_onoff = 1 l_linger = 0 lingeropt = struct.pack('ii', l_onoff, l_linger) s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) s.setsockopt(socket.SOL_SOCKET, socket.SO_LINGER, lingeropt) s.bind((host, port)) s.listen(1) while 1: try: clientsock, clientaddr = s.accept() print "Got connection from", clientsock.getpeername() data = clientsock.recv(1024*1024*10) #print "asdasd",data numsent=clientsock.send(data) data1 = clientsock.recv(1024*1024*10) numsent=clientsock.send(data) ret = 1 while(ret>0): data1 = clientsock.recv(1024*1024*10) ret = len(data) clientsock.close() except KeyboardInterrupt: raise except: print traceback.print_exc() continue Client # File: sockClient.py import socket, traceback,sys import time i = 0 while 1: try: st = time.time() s = socket.socket(socket.AF_INET,socket.SOCK_STREAM) while (s.connect_ex(('127.0.0.1',9999)) != 0): continue numsent=s.send("asd"*1000) response = s.recv(6000) numsent=s.send("asd"*1000) response = s.recv(6000) i+=1 if i == int(sys.argv[1]): break except KeyboardInterrupt: raise except: print "in exec:::::::::::::",traceback.print_exc() continue print time.time() -st

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

    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.

  • Why does ICEfaces send dispose-window request on page unload when using view-scoped bean?

    - by woflrevo
    in our application ICEfaces always sends a dispose-window request just before navigating to another JSF Page. as much as i understand this should not happen when having org.icefaces.lazyWindowScope set to true and there is no window-scoped bean involved in current request. but it happens on each link and makes our UI less responsive. but we don't have any window-scoped bean in our application. is that a bug in icefaces that the dispose request is sent when using view-scoped beans? Is it possible to disable? ViewScope is defined in JSF not in ICEfaces, it should work without this dispose request i guess... @ManagedBean(name="viewScopeBean") @ViewScoped public class ViewScopeBean { public void doSomething(){ // } } And here the example jsf: <ice:form> <ice:commandButton value="doSomething" action="#{viewScopeBean.doSomething}"/> <h:link outcome="index" value="Link to same page"/> </ice:form> To reproduce do the following using the code above: open firebug's net tab and activate persist option click doSomething-Button click "link to same page" = dispose-window will be send before navigation Dispose Request Parameters: ice.submit.type=ice.dispose.window ice.window=4guthcbue javax.faces.ViewState=-8138151632882151449%3A-6709064564386098402 Environment: ICEfaces-EE 2.0.0.GA ICEpush-EE 2.0.0.GA Mojarra 2.1.1 JRockit 1.6.0_22 WebLogic Server 10.3.4.0 ICEfaces Configuration: org.icefaces.render.auto: true [default] org.icefaces.autoid: true [default] org.icefaces.aria.enabled: true [default] org.icefaces.blockUIOnSubmit: false [default] org.icefaces.compressDOM: false [default] org.icefaces.compressResources: true [default] org.icefaces.connectionLostRedirectURI: /pages/main.jsf org.icefaces.deltaSubmit: false [default] org.icefaces.lazyPush: true [default] org.icefaces.sessionExpiredRedirectURI: /pages/main.jsf org.icefaces.standardFormSerialization: false [default] org.icefaces.strictSessionTimeout: false [default] org.icefaces.windowScopeExpiration = 1000 [default] org.icefaces.mandatoryResourceConfiguration: null [default] org.icefaces.uniqueResourceURLs: true [default] org.icefaces.lazyWindowScope: true [default] org.icefaces.disableDefaultErrorPopups: false [default]

  • Array variable initialization error in Java

    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..

  • Worksheet.Unprotect - Office Interop - Difference between 2003 and 2007

    - by sdmcnitt
    I have a .NET winforms app that automates Excel and checks for a worksheet password. The requirements are to be able to detect 1) that the protection is turned off 2) that the password is removed (protected but there is no password) 3) that the password matches the correct password from a database To meet the second requirement the program calls the Worksheet.Unprotect command with a null string, capturing the error. If error as expected, the 3rd check is made. If no error, then the Unprotect worked without a password == password was removed. The code sample below has these checks. The application can do this fine with Office 2003. I have since had my dev machine updated to Office 2007 and it no longer works as it did. When I call the Worksheet.Unprotect, Excel prompts for the password! I need to know how this should be accomplished in the new version of Excel or if there is a way to reference the old PIA. No matter what if I set a reference to Excel 11 it is replaced with the PIA for 12 in the GAC. 'return true if unprotect of worksheet does not generate an error 'all other errors will bubble up 'return false if specific error is "Password is invalid..." Try 'detect unprotected or no password If oWorksheet.ProtectContents Then 'try with no passsword and expect an error 'if no error then raise exception Dim blnRaiseException As Boolean = True Try 'oWorksheet.Unprotect(vbNullString) oWorksheet.Unprotect() Catch ex As Exception blnRaiseException = False End Try If blnRaiseException Then Throw New ExcelSheetNoPasswordException End If oWorksheet.Unprotect(strPwd) 'no error so if we get here -- success fnCheckWorksheetPwd = True 'leave as it was -- this may still cause workbook to think it is changed oWorksheet.Protect(strPwd) Else Throw New ExcelSheetNotProtectedException End If Catch COMex As System.Runtime.InteropServices.COMException 'handle error code -2146827284 If COMex.ErrorCode = -2146827284 Then 'this is the error we're looking for Else Throw End If Catch ex As Exception Throw End Try

  • 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.

  • 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

  • Alert Dialog with custom layout failing

    - by cmptrer
    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. I think I'm just missing something obvious but the fix isn't jumping out at me. How can I get this alert dialog to display?

  • 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(); }

  • 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!

  • 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" }); } }

  • 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)

  • javascript: detect if XP or Classic windows theme is enabled

    - by mkoryak
    Is there any way to detect which windows XP theme is in use? I suspect that there is no specific api call you can make, but you may be able to figure it out by checking something on some DOM element, ie feature detection. Another question: does the classic theme even exist on windows vista or windows 7? edit - this is my solution: function isXpTheme() { var rgb; var map = { "rgb(212,208,200)" : false, "rgb(236,233,216)" : true }; var $elem = $("<button>"); $elem.css("backgroundColor", "ButtonFace"); $("body").append($elem); var elem = $elem.get(0); if (document.defaultView && document.defaultView.getComputedStyle) { s = document.defaultView.getComputedStyle(elem, ""); rgb = s && s.getPropertyValue("background-color"); } else if (elem.currentStyle) { rgb = (function (el) { // get a rgb based color on IE var oRG =document.body.createTextRange(); oRG.moveToElementText(el); var iClr=oRG.queryCommandValue("BackColor"); return "rgb("+(iClr & 0xFF)+","+((iClr & 0xFF00)>>8)+","+ ((iClr & 0xFF0000)>>16)+")"; })(elem); } else if (elem.style["backgroundColor"]) { rgb = elem.style["backgroundColor"]; } else { rgb = null; } $elem.remove(); rgb = rgb.replace(/[ ]+/g,"") if(rgb){; return map[rgb]; } } Next step is to figure out what this function returns on non-xp machines and/or figure out how to detect windows boxes. I have tested this in windows XP only, so vista and windows 7 might give different color values, it should be easy to add though. Here is a demo page of this in action: http://programmingdrunk.com/current-projects/isXpTheme/

  • 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

  • T-SQL While Loop and concatenation

    - by JustinT
    I have a SQL query that is supposed to pull out a record and concat each to a string, then output that string. The important part of the query is below. DECLARE @counter int; SET @counter = 1; DECLARE @tempID varchar(50); SET @tempID = ''; DECLARE @tempCat varchar(255); SET @tempCat = ''; DECLARE @tempCatString varchar(5000); SET @tempCatString = ''; WHILE @counter <= @tempCount BEGIN SET @tempID = ( SELECT [Val] FROM #vals WHERE [ID] = @counter); SET @tempCat = (SELECT [Description] FROM [Categories] WHERE [ID] = @tempID); print @tempCat; SET @tempCatString = @tempCatString + '<br/>' + @tempCat; SET @counter = @counter + 1; END When the script runs, @tempCatString outputs as null while @tempCat always outputs correctly. Is there some reason that concatenation won't work inside a While loop? That seems wrong, since incrementing @counter works perfectly. So is there something else I'm missing?
