  • Compact representation of GUID/UUID?

    - by chakrit
    I need to generate a GUID and save it via a string representation. The string representation should be as short as possible as it will be used as part of an already-long URL string. Right now, instead of using the normal abcd-efgh-... representation, I use the raw bytes generated and base64-encode them instead, which results in a somewhat shorter string. But is it possible to make it even shorter? I'm OK with losing some degree of uniqueness and keeping a counter, but scanning all existing keys is not an option. Suggestions?

  • FileInputStream throws NullPointerException.

    - by Mohamed
    I am getting nullpointerexception, don't know what actually is causing it. I read from java docs that fileinputstream only throws securityexception so don't understand why this exception pops up. here is my code snippet. private Properties prop = new Properties(); private String settings_file_name = "settings.properties"; private String settings_dir = "\\.autograder\\"; public Properties get_settings() { String path = this.get_settings_directory(); System.out.println(path + this.settings_dir + this.settings_file_name); if (this.settings_exist(path)) { try { FileInputStream in = new FileInputStream(path + this.settings_dir + this.settings_file_name); this.prop.load(in); in.close(); } catch (IOException e) { e.printStackTrace(); } } else { this.create_settings_file(path); try{ this.prop.load(new FileInputStream(path + this.settings_dir + this.settings_file_name)); }catch (IOException ex){ //ex.printStackTrace(); } } return this.prop; } private String get_settings_directory() { String user_home = System.getProperty("user.home"); if (user_home == null) { throw new IllegalStateException("user.home==null"); } return user_home; } and here is my stacktrace: C:\Users\mohamed\.autograder\settings.properties Exception in thread "main" java.lang.NullPointerException at autograder.Settings.get_settings(Settings.java:41) at autograder.Application.start(Application.java:20) at autograder.Main.main(Main.java:19) Java Result: 1 BUILD SUCCESSFUL (total time: 0 seconds) Line 41 is: this.prop.load(in);

  • JSON array deserialization is crashing the Dalvik VM

    - by Sam
    I have some code grabbing a JSON array from my server and initially storing it as a string. This all works fine until I try and deserialize it using google's gson fromJson method. LogCat spits out the error: 04-08 17:46:35.163: ERROR/dalvikvm(401): Can't shrink stack: curFrame is in reserved area (0x41049000 0x410491c4) My code that causes the error is: String[] results = gson.fromJson(returnString, String[].class); Can anyone shed some light on what I am doing wrong?

  • How to group a complex list of objects using LINQ?

    - by Daoming Yang
    I want to select and group the products, and rank them by the number of times they occur. For example, I have an OrderList each of order object has a OrderProductVariantList(OrderLineList), and each of OrderProductVariant object has ProductVariant, and then the ProductVariant object will have a Product object which contains product information. A friend helped me with the following code. It could be compiled, but it did not return any value/result. I used the watch window for the query and it gave me "The name 'query' does not exist in the current context". Can anyone help me? Many thanks. var query = orderList.SelectMany( o => o.OrderLineList ) // results in IEnumerable<OrderProductVariant> .Select( opv => opv.ProductVariant ) .Select( pv => p.Product ) .GroupBy( p => p ) .Select( g => new { Product = g.Key, Count = g.Count() });

  • getExtra from Intent launched from a pendingIntent

    - by spagi
    Hi. I am trying to make some alarms after the user selects something with a time from a list and create a notification for it at the given time. My problem is that the "showname" that a putExtra on my Intent cant be received at the broadcast receiver. It always get null value. This is the way I do it for most of my intents but I think this time maybe because of the pendingIntent or the broadcastReceiver something need to be done differentelly. Thank you The function that sends the Intent through the pending intent public void setAlarm(String showname,String time) { String[] hourminute=time.split(":"); String hour = hourminute[0]; String minute = hourminute[1]; Calendar rightNow = Calendar.getInstance(); rightNow.set(Calendar.HOUR_OF_DAY, Integer.parseInt(hour)); rightNow.set(Calendar.MINUTE, Integer.parseInt(minute)); rightNow.set(Calendar.SECOND, 0); long t=rightNow.getTimeInMillis(); long t1=System.currentTimeMillis(); try { Intent intent = new Intent(this, alarmreceiver.class); Bundle c = new Bundle(); c.putString("showname", showname);//This is the value I want to pass intent.putExtras(c); PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 12345, intent, 0); AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, rightNow.getTimeInMillis(),pendingIntent); //Log.e("ALARM", "time of millis: "+System.currentTimeMillis()); Toast.makeText(this, "Alarm set", Toast.LENGTH_LONG).show(); } catch (Exception e) { Log.e("ALARM", "ERROR IN CODE:"+e.toString()); } } And this is the receiving end public class alarmreceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { // Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show(); Bundle b = intent.getExtras(); String showname=b.getString("showname");//This is where I suppose to receive it but its null NotificationManager manger = (NotificationManager) context .getSystemService(context.NOTIFICATION_SERVICE); Notification notification = new Notification(R.drawable.icon, "TVGuide ?pe???µ?s?", System.currentTimeMillis()); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, new Intent(context, tvguide.class), 0); notification.setLatestEventInfo(context, "?? ?????aµµa ?e????se", showname, contentIntent); notification.flags = Notification.FLAG_ONLY_ALERT_ONCE; notification.sound = Uri.parse("file:///sdcard/dominating.mp3"); notification.vibrate = new long[]{100, 250, 100, 500}; manger.notify(1, notification); } }

  • How to Edit NSF file using c#?

    - by Preeti
    Hi, I want to programaticaly change some values to NSF item and then want to save it.(i.e to edit NSF File and then save the editions) for example: I want to set Sender name of all mails to "[email protected]".(Using Domino.dll). Solution I tried: (Swaping of To and From values) String Temp_From = ((object[])docInbox.GetItemValue("From"))[0] as String; String Temp_SendTo = ((object[])docInbox.GetItemValue("SendTo"))[0] as String; docInbox.ReplaceItemValue("From", Temp_SendTo); docInbox.ReplaceItemValue("SendTo", Temp_From); docInbox.Save(true, false, false); /* Applied for following fields also: For From: AltFrom,DisplayFrom,DisplayFrom_2,dspFrom,ForwardedFrom,INetFrom,tmpDisplayFrom For To : displaySendTo,EnterSendTo,Envelope_to,tmpDisplaySendTo Also Tried for saving : docInbox.Save(true, true, true); */ In above code after successful editing changes values are not reflected in Nsf File. But when i am reading edited Nsf (copying modified file on different location ) file programatically it is showing changed values.(Why changes are not visible here ?)

  • How can I Unescape and Reescape strings in .net?

    - by firoso
    So here's my situation. I am working on an editor for a communications channel that works over an RS232 serial ASCII terminal. Let's not go into detail for that ;-) To simplify, I need a textbox on a WPF control that can take in text like "Commit\r\n" (which is the .net string "Commit\r\n") and convert it back to "Commit\r\n" as a .net string. I was hoping for a string.Unescape() and string.Escape() method pair, but it doesn't seem to exist. Am I going to have to write my own? or is there a more simple way to do this?

  • Problem with Java Mail : No provider for smtp

    - by user359198
    Hello all. I am using JavaMail to do a simple application that sends an email when it finds some files in a directory. I managed to get it worked from Eclipse. I Run the application and it sent the email with no errors. But, when I created the jar, and executed it, it fails in the email sending part. It gives this exception. javax.mail.NoSuchProviderException: No provider for smtp at javax.mail.Session.getProvider(Session.java:460) at javax.mail.Session.getTransport(Session.java:655) at javax.mail.Session.getTransport(Session.java:636) at main.java.util.MailManager.sendMail(MailManager.java:69) at main.java.DownloadsMail.composeAndSendMail(DownloadsMail.java:16) at main.java.DownloadsController.checkDownloads(DownloadsController.java:51) at main.java.MainDownloadsController.run(MainDownloadsController.java:26) at java.lang.Thread.run(Unknown Source) I am using the library in this method: public static boolean sendMail(String subject, String text){ noExceptionsThrown = true; try { loadProperties(); } catch (IOException e1) { System.out.println("Problem encountered while loading properties"); e1.printStackTrace(); noExceptionsThrown = false; } Properties mailProps = new Properties(); String host = "mail.smtp.host"; mailProps.setProperty(host, connectionProps.getProperty(host)); String tls = "mail.smtp.starttls.enable"; mailProps.setProperty(tls, connectionProps.getProperty(tls)); String port = "mail.smtp.port"; mailProps.setProperty(port, connectionProps.getProperty(port)); String user = "mail.smtp.user"; mailProps.setProperty(user, connectionProps.getProperty(user)); String auth = "mail.smtp.auth"; mailProps.setProperty(auth, connectionProps.getProperty(auth)); Session session = Session.getDefaultInstance(mailProps); //session.setDebug(true); MimeMessage message = new MimeMessage(session); try { message.setFrom(new InternetAddress(messageProps.getProperty("from"))); message.addRecipient(Message.RecipientType.TO, new InternetAddress( messageProps.getProperty("to"))); message.setSubject(subject); message.setText(text); Transport t = session.getTransport("smtp"); try { t.connect(connectionProps.getProperty("user"), passwordProps .getProperty("password")); t.sendMessage(message, message.getAllRecipients()); } catch (Exception e) { System.out.println("Error encountered while sending the email"); e.printStackTrace(); noExceptionsThrown = false; } finally { t.close(); } } catch (Exception e) { System.out.println("Error encountered while creating the message"); e.printStackTrace(); noExceptionsThrown = false; } return noExceptionsThrown; } I am loading these values from properties files. mail.smtp.host=smtp.gmail.com mail.smtp.starttls.enable=true mail.smtp.port=587 mail.smtp.auth=true I have tried to change the host by ssl://smtp.gmail.com, the port by 465 (just for trying something different), but it doesn't work either. Anyway, if it works fine from Eclipse with the original parameters, I guess that the values are correct, but the problem is creating the jar. I don't know very much about the possible results or changes when creating a jar. Could the JavaMail libraries someway go wrong when the jar is created? Do you have any ideas? Thank you very much for your help.

  • Java generics parameters with base of the generic parameter

    - by Iulian Serbanoiu
    Hello, I am wondering if there's an elegant solution for doing this in Java (besides the obvious one - of declaring a different/explicit function. Here is the code: private static HashMap<String, Integer> nameStringIndexMap = new HashMap<String, Integer>(); private static HashMap<Buffer, Integer> nameBufferIndexMap = new HashMap<Buffer, Integer>(); // and a function private static String newName(Object object, HashMap<Object, Integer> nameIndexMap){ .... } The problem is that I cannot pass nameStringIndexMap or nameBufferIndexMap parameters to the function. I don't have an idea about a more elegant solution beside doing another function which explicitly wants a HashMap<String, Integer> or HashMap<Buffer, Integer> parameter. My question is: Can this be made in a more elegant solution/using generics or something similar? Thank you, Iulian

  • ws-xmlrpc claims error on part of service but other clients work fine

    - by mludd
    I've been trying to connect to an rTorrent instance using ws-xmlrpc and it just isn't going too well. Now, the URL I'm using is the same that I've been using when making sure that rTorrent's XMLRPC support is fine (which it appears to be since both a native OS X application and a small python script I threw together appear to be able to talk to it just fine without any errors). However, when I try using ws-xmlrpc to connect I get org.apache.xmlrpc.XmlRpcException: Failed to create input stream: Unexpected end of file from serverat the top of my stack trace followed by a bunch of steps down to: java.net.SocketException: Unexpected end of file from server at sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:769) ... So basically, it seems that ws-xmlrpc is convinced that the reply from rTorrent is malformed somehow but other libraries apparently have no problem with it. The code I use to call rTorrent is: private Object callRTorrent(String command, Object[] params) { Object result = null; try { // xmlrpcclient is an XmlRpcClient object and is instantied in // the class constructor result = xmlrpcclient.execute(command, params); } catch(XmlRpcException xre) { System.out.println("Unable to execute method "+command); xre.printStackTrace(); } return result; } With command set to system.listMethodsand params set to an empty Object[]. From reading documentation and googling my conclusion is that I'm not doing anything obviously wrong and this problem doesn't appear to be common, so does anyone have a clue what's going on here?

  • Linq-to-sql Compiled Query is caching result from disposed DataContext

    - by Vladimir Kojic
    Compiled query: public static Func<OperationalDataContext, short, Machine> QueryMachineById = CompiledQuery.Compile((OperationalDataContext db, short machineID) => db.Machines.Where(m => m.MachineID == machineID).SingleOrDefault()); It looks like compiled query is caching Machine object and returning the same object even if query is called from new DataContext (I’m disposing DataContext in the service but I’m getting Machine from previous DataContext). I use POCOs and XML mapping. Getting cached object from the same datacontext is ok, but when I call query with new DataContext I don’t want to get object from old datacontext. Is there something that I don’t do right ? Thanks, Vladimir

  • Error when changing default lanuage in asp.net compilation from vb to c#

    - by Herman
    Hi all, We have a updatable web site project that is written in c#, it has the usual web form implementation using master page, skins, user controls,...etc. Up to this point we neglect to change the default compilation language from VB to C#. However, the second we change it, we see the following error. Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at ASP.Default.__DataBinding__control499(Object sender, EventArgs e) at System.Web.UI.Control.OnDataBinding(EventArgs e) at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBindChildren() at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBindChildren() at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBindChildren() at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBindChildren() at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at .... Further investigation points out that this error is getting generated from a Theme related assembly (Source : App_Theme_Default.zclakrlo). Any ideas? One of my co-worker suggested that it might be skin file related since we have a theme call "Default" and there is no way to specify a language on a skin file. Therefore, when the asp.net runtime tries to compile it under C#, it will give a name collision? Does this make sense? Any help is appreciated.

  • A Question about .net Rfc2898DeriveBytes class?

    - by IbrarMumtaz
    What is the difference in this class? as posed to just using Encoding.ASCII.GetBytes(string object); I have had relative success with either approach, the former is a more long winded approach where as the latter is simple and to the point. Both seem to allow you to do the same thing eventually but I am struggling to the see the point in using the former over the latter. The basic concept I have been able to grasp is that you can convert string passwords into byte arrays to be used for e.g a symmetric encryption class, AesManaged. Via the RFC class but you get to use SaltValues and password when creating your rfc object. I assume its more secure but still thats an uneducated guess at best ! Also that it allows you to return byte arrays of a certain size, well something like that. heres a few examples to show you where I am coming from? byte[] myPassinBytes = Encoding.ASCII.GetBytes("some password"); or string password = "P@%5w0r]>"; byte[] saltArray = Encoding.ASCII.GetBytes("this is my salt"); Rfc2898DeriveBytes rfcKey = new Rfc2898DeriveBytes(password, saltArray); The 'rfcKey' object can now be used towards setting up the the .Key or .IV properties on a Symmetric Encryption Algorithm class. ie. RijndaelManaged rj = new RijndaelManaged (); rj.Key = rfcKey.Getbytes(rj.KeySize / 8); rj.IV = rfcKey.Getbytes(rj.Blocksize / 8); 'rj' should be ready to go ! The confusing part ... so rather than using the 'rfcKey' object can I not just use my 'myPassInBytes' array to help set-up my 'rj' object???? I have tried doing this in VS2008 and the immediate answer is NO ! but have you guys got a better educated answer as to why the RFC class is used over the other alternative I have mentioned above and why????

  • Scala: How to combine parser combinators from different objects

    - by eed3si9n
    Given a family of objects that implement parser combinators, how do I combine the parsers? Since Parsers.Parser is an inner class, and in Scala inner classes are bound to the outer object, the story becomes slightly complicated. Here's an example that attempts to combine two parsers from different objects. import scala.util.parsing.combinator._ class BinaryParser extends JavaTokenParsers { def anyrep: Parser[Any] = rep(any) def any: Parser[Any] = zero | one def zero: Parser[Any] = "0" def one: Parser[Any] = "1" } object LongChainParser extends BinaryParser { def parser1: Parser[Any] = zero~zero~one~one } object ShortChainParser extends BinaryParser { def parser2: Parser[Any] = zero~zero } object ExampleParser extends BinaryParser { def parser: Parser[Any] = (LongChainParser.parser1 ||| ShortChainParser.parser2) ~ anyrep def main(args: Array[String]) { println(parseAll(parser, args(0) )) } } This results to the following error: <console>:11: error: type mismatch; found : ShortChainParser.Parser[Any] required: LongChainParser.Parser[?] def parser: Parser[Any] = (LongChainParser.parser1 ||| ShortChainParser.parser2) ~ anyrep I've found the solution to this problem already, but since it was brought up recently on scala-user ML (Problem injecting one parser into another), it's probably worth putting it here too.

  • Android : ugly TABS in 2.0 vs 1.5 ... why ? where are my rounded corners TABS ?

    I simply use the tabwidget : mTabHost = getTabHost(); mTabHost.addTab(mTabHost.newTabSpec("tab_1").setIndicator(getString(R.string.day0)).setContent(R.id.tab1_content)); mTabHost.addTab(mTabHost.newTabSpec("tab_2").setIndicator(getString(R.string.day1)).setContent(R.id.tab2_content)); mTabHost.addTab(mTabHost.newTabSpec("tab_3").setIndicator(getString(R.string.day2)).setContent(R.id.tab3_content)); mTabHost.addTab(mTabHost.newTabSpec("tab_4").setIndicator(getString(R.string.day3)).setContent(R.id.tab4_content)); mTabHost.addTab(mTabHost.newTabSpec("tab_5").setIndicator(getString(R.string.about)).setContent(R.id.tab5_content)); mTabHost.setCurrentTab(0); Why are my tabs so uggly in 2.0 (no more rounded corners as in 1.5/1.6) ? ugly tabs here = this was better What should I do now to show "rounded corners" TABS to Nexus One (for exemple) users ;-) ? Is it because of the following manifest lines : <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4" /> <supports-screens android:smallScreens="true" android:normalScreens="true" android:largeScreens="true" android:anyDensity="true" /> I have to keep android:anyDensity="true" otherwise I've got a problem with re-sizing of the menus described here As a separate question, my users can change the Locale within my app itself, I then "redraw" the menus using onPrepareOptionsMenu (Menu menu) to refresh the strings within the menu with the new language choosen by the user. Is there an equivalent for TABS (I have local strings within the Title of the TABS) or do I have to delete all the tabs and re-create them from scratch ? Txs in advance for your help. Hub

  • C# Delegate Invoke Required Issue

    - by Goober
    Scenario I have a C# windows forms application that has a number of processes. These processes run on separate threads and all communicate back to the Main Form class with updates to a log window and a progress bar. I'm using the following code below, which up until now has worked fine, however, I have a few questions. Code delegate void SetTextCallback(string mxID, string text); public void UpdateLog(string mxID, string text) { if (txtOutput.InvokeRequired) { SetTextCallback d = new SetTextCallback(UpdateLog); this.BeginInvoke(d, new object[] { mxID, text }); } else { UpdateProgressBar(text); } } Question Will, calling the above code about 10 times a second, repeatedly, give me errors, exceptions or generally issues?.....Or more to the point, should it give me any of these problems? Occasionally I get OutofMemory Exceptions and the program always seems to crash around this bit of code......

  • Sending Email from Lotus Notes using Excel and having Attachment & HTML body

    - by Anthony
    Right I'm trying to send an Email form an excel spreadsheet though lotus notes, it has an attachment and the body needs to be in HTML. I've got some code that from all I've read should allow me to do this however it doesn't. Without the HTML body the attachment will send, when I impliment a HTML body the Email still sends but the attachment dissapears, I've tried rearanging the order of the code cutting out bits that might not be needed but all is invain. (You need to reference Lotus Domino Objects to run this code. strEmail is the email addresses strAttach is the string location of the attachment strSubject is the subject text strBody is the body text ) Sub Send_Lotus_Email(strEmail, strAttach, strSubject, strBody) Dim noSession As Object, noDatabase As Object, noDocument As Object Dim obAttachment As Object, EmbedObject As Object Const EMBED_ATTACHMENT As Long = 1454 Set noSession = CreateObject("Notes.NotesSession") Set noDatabase = noSession.GETDATABASE("", "") 'If Lotus Notes is not open then open the mail-part of it. If noDatabase.IsOpen = False Then noDatabase.OPENMAIL 'Create the e-mail and the attachment. Set noDocument = noDatabase.CreateDocument Set obAttachment = noDocument.CreateRichTextItem("strAttach") Set EmbedObject = obAttachment.EmbedObject(EMBED_ATTACHMENT, "", strAttach) 'Add values to the created e-mail main properties. With noDocument .Form = "Memo" .SendTo = strEmail '.Body = strBody ' Where to send the body if HTML body isn't used. .Subject = strSubject .SaveMessageOnSend = True End With noSession.ConvertMIME = False Set Body = noDocument.CreateMIMEEntity("Body") ' MIMEEntity to support HTML Set stream = noSession.CreateStream Call stream.WriteText(strBody) ' Write the body text to the stream Call Body.SetContentFromText(stream, "text/html;charset=iso-8859-1", ENC_IDENTITY_8BIT) noSession.ConvertMIME = True 'Send the e-mail. With noDocument .PostedDate = Now() .Send 0, strEmail End With 'Release objects from the memory. Set EmbedObject = Nothing Set obAttachment = Nothing Set noDocument = Nothing Set noDatabase = Nothing Set noSession = Nothing End Sub If somone could point me in the right direction I'd be greatly appreciated. Edit: I've done a little more investigating and I've found an oddity, if i look at the sent folder the emails all have the paperclip icon of having an attachment even though when you go into the email even in the sent the HTML ones don't show an attachment.

  • EXC_BAD_ACCESS in CFAttributedStringSetAttribute and NSNumber?

    - by RichardR
    Hi all, I am getting an infuriating EXC_BAD_ACCESS error in an objective c app I am working on. Any help you could offer would be much appreciated. I have tried the normal debug methods for this error (turning on NSZombieEnabled, checking retain/release/autorelease to make sure I'm not trying to access a deallocated object, etc.) and it hasn't seemed to help. Basically, the error always occurs in this function: ` void op_TJ(CGPDFScannerRef scanner, void *info) { PDFPage *self = info; CGPDFArrayRef array; NSMutableString *tempString = [NSMutableString stringWithCapacity:1]; NSMutableArray *kernArray = [[NSMutableArray alloc] initWithCapacity:1]; if(!CGPDFScannerPopArray(scanner, &array)) { [kernArray release]; return; } for(size_t n = 0; n < CGPDFArrayGetCount(array); n += 2) { if(n >= CGPDFArrayGetCount(array)) continue; CGPDFStringRef pdfString; // if we get a PDF string if (CGPDFArrayGetString(array, n, &pdfString)) { //get the actual string const unsigned char *charstring = CGPDFStringGetBytePtr(pdfString); //add this string to our temp string [tempString appendString:[NSString stringWithCString:(const char*)charstring encoding:[self pageEncoding]]]; //NSLog(@"string: %@", tempString); //get the space after this string CGPDFReal r = 0; if (n+1 < CGPDFArrayGetCount(array)) { CGPDFArrayGetNumber(array, n+1, &r); // multiply by the font size CGFloat k = r; k = -k/1000 * self.tmatrix.a * self.fontSize; CGFloat kKern = self.kern * self.tmatrix.a; k = k + kKern; // add the location and kern to the array NSNumber *tempKern = [NSNumber numberWithFloat:k]; NSLog(@"tempKern address: %p", tempKern); [kernArray addObject:[NSArray arrayWithObjects:[NSNumber numberWithInt:[tempString length] - 1], tempKern, nil]]; } } } // create an attribute string CFMutableAttributedStringRef attString = CFAttributedStringCreateMutable(kCFAllocatorDefault, 10); CFAttributedStringReplaceString(attString, CFRangeMake(0, 0), (CFStringRef)tempString); //apply overall kerning NSNumber *tkern = [NSNumber numberWithFloat:self.kern * self.tmatrix.a * self.fontSize]; CFAttributedStringSetAttribute(attString, CFRangeMake(0, CFAttributedStringGetLength(attString)), kCTKernAttributeName, (CFNumberRef)tkern); //apply individual kern attributes for (NSArray *kernLoc in kernArray) { NSLog(@"kern location: %i, %i", [[kernLoc objectAtIndex:0] intValue],[[kernLoc objectAtIndex:1] floatValue]); CFAttributedStringSetAttribute(attString, CFRangeMake([[kernLoc objectAtIndex:0] intValue], 1), kCTKernAttributeName, (CFNumberRef)[kernLoc objectAtIndex:1]); } CFAttributedStringReplaceAttributedString([self cfAttString], CFRangeMake(CFAttributedStringGetLength([self cfAttString]), 0), attString); //release CFRelease(attString); [kernArray release]; } ` The program always crashes because of line CFAttributedStringSetAttribute(attString, CFRangeMake([[kernLoc objectAtIndex:0] intValue], 1), kCTKernAttributeName, (CFNumberRef)[kernLoc objectAtIndex:1]) And it seems to depend on a few things: if [kernLoc objectAtIndex:1] refers to an [NSNumber numberWithFloat:k] where k = 0 (in other words, if k = 0 above where I populate kernArray) then the program crashes almost immediately If I comment out the line k = k + kKern, it takes longer for the program to crash, but does eventually (why would the crash depend on this value?) If I change the length of CFRangeMake from 1 to 0, it takes a lot longer for the program to crash, but still eventually does. (I don't think I am trying to access beyond the bounds of attString, but am I missing something?) When it crashes, I get something similar to: #0 0x942c7ed7 in objc_msgSend () #1 0x00000013 in ?? () #2 0x0285b827 in CFAttributedStringSetAttribute () #3 0x0000568f in op_TJ (scanner=0x472a590, info=0x4a32320) at /Users/Richard/Desktop/AppTest/PDFHighlight 2/PDFScannerOperators.m:251 Any ideas? It seems like somewhere along the way I am overwriting memory or trying to access memory that has been changed, but I have no idea. If there's anymore information I can provide, please let me know. Thanks, Richard

  • How can I tell the Data Annotations validator to also validate complex child properties?

    - by GWB
    Can I automatically validate complex child objects when validating a parent object and include the results in the populated ICollection<ValidationResult>? If I run the following code: using System; using System.Collections.Generic; using System.ComponentModel.DataAnnotations; namespace ConsoleApplication1 { public class Person { [Required] public string Name { get; set; } public Address Address { get; set; } } public class Address { [Required] public string Street { get; set; } [Required] public string City { get; set; } [Required] public string State { get; set; } } class Program { static void Main(string[] args) { Person person = new Person { Name = null, Address = new Address { Street = "123 Any St", City = "New York", State = null } }; var validationContext = new ValidationContext(person, null, null); var validationResults = new List<ValidationResult>(); var isValid = Validator.TryValidateObject(person, validationContext, validationResults); Console.WriteLine(isValid); validationResults.ForEach(r => Console.WriteLine(r.ErrorMessage)); Console.ReadKey(true); } } } I get the following output: False The Name field is required. But I was expecting something similar to: False The Name field is required. The State field is required.

  • Anything wrong with spamming GC.KeepAlive(KeyboardHookPointer)?

    - by Alex
    GC.KeepAlive() References the specified object, which makes it ineligible for garbage collection from the start of the current routine to the point where this method is called. Not really sure about what GC.KeepAlive does other than simply store a reference so the Garbage Collector doesn't collect the object. But does calling GC.KeepAlive() on an object permanently keep an object from being collected? Or do you have to re-call GC.KeepAlive() every so often (and if so, how often)? I want to keep my keyboard hook alive.
