  • How do I handle all the exceptions in a C# class where both ctor and finalizer throw exceptions?

    - by Frank
    How can I handle all exceptions for a class similar to the following under certain circumstances? class Test : IDisposable { public Test() { throw new Exception("Exception in ctor"); } public void Dispose() { throw new Exception("Exception in Dispose()"); } ~Test() { this.Dispose(); } } I tried this but it doesn't work: static void Main() { Test t = null; try { t = new Test(); } catch (Exception ex) { Console.Error.WriteLine(ex.Message); } // t is still null } I have also tried to use "using" but it does not handle the exception thrown from ~Test(); static void Main() { try { using (Test t = new Test()) { } } catch (Exception ex) { Console.Error.WriteLine(ex.Message); } } Any ideas how can I work around?

  • Use trackball for scrolling in Android ListView

    - by gartenkralleb
    hi, i have a ListView, whose content should not be selectable. i set the ListView to choiceMode="none" and set a transparent listSelector. for touch mode it acts as desired. a problem is the use of the trackball. if i try to use it for scrolling, the scroll starts after the 10th push to "down". this is caused by the invisible listSelector, which scrolls down the list until the 10th list item is "invisibily" selected. i try to override dispatchTrackballEvent and do the scrolling with scrollBy, but i did not finished this approach yet, to have a look on alternative suggestions. is there a simple solution for my problem?

  • printf field width : bytes or chars?

    - by leonbloy
    The printf/fprintf/sprintf family supports a width field in its format specifier. I have a doubt for the case of (non-wide) char arrays arguments: Is the width field supposed to mean bytes or characters? What is the (correct-de facto) behaviour if the char array corresponds to (say) a raw UTF-8 string? (I know that normally I should use some wide char type, that's not the point) For example, in char s[] = "ni\xc3\xb1o"; // utf8 encoded "niño" fprintf(f,"%5s",s); Is that function supposed to try to ouput just 5 bytes (plain C chars) (and you take responsability of misalignments or other problems if two bytes results in a textual characters) ? Or is it supposed to try to compute the length of "textual characters" of the array? (decodifying it... according to the current locale?) (in the example, this would amount to find out that the string has 4 unicode chars, so it would add a space for padding).

  • How do I make my multicast program work between computers on different networks?

    - by George
    I made a little chat applet using multicast. It works fine between computers on the same network, but fails if the computers are on different networks. Why is this? import java.io.*; import java.net.*; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class ClientA extends JApplet implements ActionListener, Runnable { JTextField tf; JTextArea ta; MulticastSocket socket; InetAddress group; String name=""; public void start() { try { socket = new MulticastSocket(7777); group = InetAddress.getByName("233.0.0.1"); socket.joinGroup(group); socket.setTimeToLive(255); Thread th = new Thread(this); th.start(); name =JOptionPane.showInputDialog(null,"Please enter your name.","What is your name?",JOptionPane.PLAIN_MESSAGE); tf.grabFocus(); }catch(Exception e) {e.printStackTrace();} } public void init() { JPanel p = new JPanel(new BorderLayout()); ta = new JTextArea(); ta.setEditable(false); ta.setLineWrap(true); JScrollPane sp = new JScrollPane(ta); p.add(sp,BorderLayout.CENTER); JPanel p2 = new JPanel(); tf = new JTextField(30); tf.addActionListener(this); p2.add(tf); JButton b = new JButton("Send"); b.addActionListener(this); p2.add(b); p.add(p2,BorderLayout.SOUTH); add(p); } public void actionPerformed(ActionEvent ae) { String message = name+":"+tf.getText(); tf.setText(""); tf.grabFocus(); byte[] buf = message.getBytes(); DatagramPacket packet = new DatagramPacket(buf,buf.length, group,7777); try { socket.send(packet); } catch(Exception e) {} } public void run() { while(true) { byte[] buf = new byte[256]; String received = ""; DatagramPacket packet = new DatagramPacket(buf, buf.length); try { socket.receive(packet); received = new String(packet.getData()).trim(); } catch(Exception e) {} ta.append(received +"\n"); ta.setCaretPosition(ta.getDocument().getLength()); } } }

  • .NET Impersonate not working!

    - by Jagd
    I have a webpage that allows a user to upload a file to a network share. When I run the webpage locally (within VS 2008) and try to upload the file, it works! However, when I deploy the website to the webserver and try to upload the file through the webpage, it doesn't work! The error being returned to me on the webserver says "Access to the path '\05prd1\emp\test.txt' is denied. So, obviously, this is a permissions issue. The network share is configured to allow full access both to me (NT authentication) and to the NETWORK SERVICE (which is .NET's default account and what we have set in our IIS application pool as the default user for this website). I have tried this with and without authentication, and neither one works on the webserver, yet both ways works on my local machine. The code that does the file upload is below. Please note that the code below includes impersonation, but like I said above, I've tried it with and without impersonation and it's made no difference. if (fuCourses.PostedFile != null && fuCourses.PostedFile.ContentLength > 0) { System.Security.Principal.WindowsImpersonationContext impCtx; impCtx = ((System.Security.Principal.WindowsIdentity)User.Identity).Impersonate(); try { lblMsg.Visible = true; // The courses file to be uploaded HttpPostedFile file = fuCourses.PostedFile; string fName = file.FileName; string uploadPath = "\\\\05prd1\\emp\\"; // Get the file name if (fName.Contains("\\")) { fName = fName.Substring( fName.LastIndexOf("\\") + 1); } // Delete the courses file if it is already on \\05prd1\emp FileInfo fi = new FileInfo(uploadPath + fName); if (fi != null && fi.Exists) { fi.Delete(); } // Open new file stream on \\05prd1\emp and read bytes into it from file upload FileStream fs = File.Create(uploadPath + fName, file.ContentLength); using (Stream stream = file.InputStream) { byte[] b = new byte[4096]; int read; while ((read = stream.Read(b, 0, b.Length)) > 0) { fs.Write(b, 0, read); } } fs.Close(); lblMsg.Text = "File Successfully Uploaded"; lblMsg.ForeColor = System.Drawing.Color.Green; } catch (Exception ex) { lblMsg.Text = ex.Message; lblMsg.ForeColor = System.Drawing.Color.Red; } finally { impCtx.Undo(); } } Any help on this would be very appreciated!

  • Skip "Sign in to your Microsoft account" (Windows 8.1 Setup)

    - by noloader
    I have an RT tablet and updated it to Windows 8.1. The update basically performs the new PC setup. I can't get past the "Sign into your Microsoft Account". Clicking "Next" does not allow me to proceed (and prompts me for an email address). Clicking "Don't have an account" does nothing because its not linked. The other two options are "Create an account" a "Privacy statement". I don't want to create an account, and I'm not interested in their perverted terms of service for an account. In Windows 8.0, we were given the option to use local authentication. How do I bypass this feature?

    Hi all, I've been struggling with this for quit a while... Googling all sorts of things has brought up anything useful so far. I have MAMP 1.8.4 install on my MBP running snow leopard - i want to upgrade to PHP to 5.3 to fit to my new job's working environment.. however i can't seem to get it to work. I've tried downloading the 5.3 source and compiling it using's MAMP's ./configure statement but i always get an error regarding apxs and a possibly missing config_vars.mk file from that i understand. Has anyone been able to do this successfully? If so how? What were to happen if i were to drop the --with-apxs from the configure line? would it break the apache/php ?

  • Bulkinsert from CSV into db (C#) -> max number of rows in a web application?

    - by Swoosh
    Web application - C#, .Net, SQL 2k5. I recently used bulkinsert on an other application and I thought I would like to give it a try. I am going to receive a CSV file with 1000 rows, which will most likely add 500 000 (that is five hundred thousand) records in the database. I don't have any idea yet about this huge amount if it's going to work out well. I am afraid that it will time out. I didn't do any testing yet, but I am pretty sure it would time out eventually. Is there a way to make it not time out (I don't know ... split the bulkinsert into 1000 pieces :D) or I should try to do something like BCP, with a SQL job ...

  • Converting raw bytes into audio sound

    - by Afro Genius
    In my application I inherit a javastreamingaudio class from the freeTTS package then bypass the write method which sends an array of bytes to the SourceDataLine for audio processing. Instead of writing to the data line, I write this and subsequent byte arrays into a buffer which I then bring into my class and try to process into sound. My application processes sound as arrays of floats so I convert to float and try to process but always get static sound back. I am sure this is the way to go but am missing something along the way. I know that sound is processed as frames and each frame is a group of bytes so in my application I have to process the bytes into frames somehow. Am I looking at this the right way? Thanx in advance for any help.

  • Cannot Extend Django 1.2.1 Admin Template

    - by jcady
    I am attempting to override/extend the header for the Django admin in version 1.2.1. However when I try to extend the admin template and simply change what I need documented here: http://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-vs-replacing-an-admin-template), I run into a recursion problem. I have an index.html file in my project's templates/admin/ directory that starts with {% extends "admin/index.html" %} But it seems that this is referencing the local index file (a.k.a. itself) rather than the default Django copy. I want to extend the default Django template and simply change a few blocks. When I try this file, I get a recursion depth error. How can I extend parts of the admin? Thanks.

  • Using VRaptor3 with Tomcat UnpackWARs property setted to false

    - by VinTem
    Hi there, I have to deploy my web app to a tomcat container with the unpackWARs property defined to false. When I do that, although the application is successfully deployed, when I try to access my url I always got a 404 error. I just don't receive that error when I try to access a direct file like index.html for instance. But I can't do that, the VRaptor framework is responsible for routing my url to the jsp file. Does anyone know if I have do anything else? Thanx

  • .NET and Closing MSSQL connections

  • Avoiding Mixup of Language Details

    - by DarenW
    Today someone asked me what was wrong with their source code. It was obvious. "Use double equals in place of that single equal in that if statement. Um, i think..." As i remember some languages actually take a single equals for comparison. Since i sometimes forget or mix up the syntax details among the several languages i use, i stepped over to my laptop to try a quickie experiment... It costs a bit of time and is a break in the flow to try "quick" experiments (though maybe the practice is good for memory.) What tips do you have for keeping straight in your mind the syntax (and other) details of multiple languages? (And nowadays, this applies just as well to the many wiki-like markups!)

  • Classes missing if application runs for a long time

    - by Rogach
    I have a funny problem - if my application runs for a long time ( 20h), then sometimes I get NoClassDefFound error - seems like JVM decided that the class is not going to be used anyway and GCd it. To be a bit more specific, here's an example case: object ErrorHandler extends PartialFunction[Throwable,Unit] { def isDefinedAt(t: Throwable) = true def apply(e: Throwable) =e match { // ... handle errors } } // somewhere else in the code... try { // ... long running code, can take more than 20 hours to complete } catch (ErrorHandler) And I get the following exception: Exception in thread "main" java.lang.NoClassDefFoundError: org/rogach/avalanche/ErrorHandler$ If that try/catch block runs for smaller amounts of time, everything works as expected. If anyone is interested, here is the codebase in question: Avalanche I need to note that I saw this and similar problems only on Cent OS 5 machines, using JRE 6u26 and Scala 2.9.1 / 2.9.2. What could be the cause of this problem?

  • What to Return? Error String, Bool with Error String Out, or Void with Exception

    - by Ranger Pretzel
    I spend most of my time in C# and am trying to figure out which is the best practice for handling an exception and cleanly return an error message from a called method back to the calling method. For example, here is some ActiveDirectory authentication code. Please imagine this Method as part of a Class (and not just a standalone function.) bool IsUserAuthenticated(string domain, string user, string pass, out errStr) { bool authentic = false; try { // Instantiate Directory Entry object DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, user, pass); // Force connection over network to authenticate object nativeObject = entry.NativeObject; // No exception thrown? We must be good, then. authentic = true; } catch (Exception e) { errStr = e.Message().ToString(); } return authentic; } The advantages of doing it this way are a clear YES or NO that you can embed right in your If-Then-Else statement. The downside is that it also requires the person using the method to supply a string to get the Error back (if any.) I guess I could overload this method with the same parameters minus the "out errStr", but ignoring the error seems like a bad idea since there can be many reasons for such a failure... Alternatively, I could write a method that returns an Error String (instead of using "out errStr") in which a returned empty string means that the user authenticated fine. string AuthenticateUser(string domain, string user, string pass) { string errStr = ""; try { // Instantiate Directory Entry object DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, user, pass); // Force connection over network to authenticate object nativeObject = entry.NativeObject; } catch (Exception e) { errStr = e.Message().ToString(); } return errStr; } But this seems like a "weak" way of doing things. Or should I just make my method "void" and just not handle the exception so that it gets passed back to the calling function? void AuthenticateUser(string domain, string user, string pass) { // Instantiate Directory Entry object DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, user, pass); // Force connection over network to authenticate object nativeObject = entry.NativeObject; } This seems the most sane to me (for some reason). Yet at the same time, the only real advantage of wrapping those 2 lines over just typing those 2 lines everywhere I need to authenticate is that I don't need to include the "LDAP://" string. The downside with this way of doing it is that the user has to put this method in a try-catch block. Thoughts? Is there another way of doing this that I'm not thinking of?

  • File size and mime-type before upload

    - by Marcos Placona
    Hi, I've scavenged on every single topic on this forum to try and find an answer before I posted this. Most people say you should simply use SWFUpload, some others mention Activex, and it keeps going. I know this is do-able, as Google does it with gMail when you try to upload a file that's bigger than 25mb, or executable. My question is, how can I determine the file size and mime-type before the file actually hits my server. I primarily thought it was an impossible task, but Google proves me wrong. Could anyone give me a definitive answer on how to accomplish such task? Thanks

  • Django admin causes high load for one model...

    - by Joe
    In my Django admin, when I try to view/edit objects from one particular model class the memory usage and CPU rockets up and I have to restart the server. I can view the list of objects fine, but the problem comes when I click on one of the objects. Other models are fine. Working with the object in code (i.e. creating and displaying) is ok, the problem only arises when I try to view an object with the admin interface. The class isn't even particularly exotic: class Comment(models.Model): user = models.ForeignKey(User) thing = models.ForeignKey(Thing) date = models.DateTimeField(auto_now_add=True) content = models.TextField(blank=True, null=True) approved = models.BooleanField(default=True) class Meta: ordering = ['-date'] Any ideas? I'm stumped. The only reason I could think of might be that the thing is quite a large object (a few kb), but as I understand it, it wouldn't get loaded until it was needed (correct?).

  • Problem authenticating with shiro in grails app

    - by xain
    I have a grails 1.2 app and I want to use declarative security in order to restrict accesses based on roles. I decided to try shiro, installed the plugin, but when I try to authenticate, the message "Invalid username and/or password" shows up in the header. I check the db entry and the user is there with the sha'ed password. No messages are shown neither in the console nor in the stacktrace file. I added "warn 'org.jsecurity'" to Config.groovy with no results. Any hints/tricks to troubleshoot this ?

  • What is your ratio Bug fixing vs Enhancements ?

    - by Newtopian
    In the spirit of this question I wanted to have a sense of what is the proportion of time split between fixing bugs and implementing new features. If possible try to give an estimate for the product as a whole as opposed to individual developer stats and try to make an average over the course of a typical year. Do provide a general descriptive of the product/project to allow comparison. Specifically : Maturity of project Is it still actively developed or strictly in maintenance ? Size estimate of the product/project Size of team developing it (all inclusive) What is your team score on the Joel test. Ex : approx 80% time spent bug fixes 20% new stuff Mature software (20 years old) Actively developed 1.5M Line of Text, approx 700k - 900k LOC 12-15 actively coding in it. we got 5/12 for sure, some would say 7/12.

  • Creating VSTO Excel Template fails

    - by Phil.Wheeler
    I have been trying for ages in all sorts of ways (short of ritual incantations and sacrifices) to get Visual Studio Team Edition 2008 to allow me to create Office 2003 solutions, whether those be templates or documents. No matter what I try, I'm always presented with an error which basically says "You've got the wrong version of Office installed. Try installing something compatible". I have the complete installation of Office 2003 Pro installed along with the Office 2003 Primary Interop Assemblies (which I put on after I installed Office) and then VS2008TE as already mentioned. There has to be some reason why this refuses to work, but I'm out of ideas. Help appreciated.

  • Restoring multiple database backups in a transaction

    - by Raghu Dodda
    I wrote a stored procedure that restores as set of the database backups. It takes two parameters - a source directory and a restore directory. The procedure looks for all .bak files in the source directory (recursively) and restores all the databases. The stored procedure works as expected, but it has one issue - if I uncomment the try-catch statements, the procedure terminates with the following error: error_number = 3013 error_severity = 16 error_state = 1 error_message = DATABASE is terminating abnormally. The weird part is sometimes (it is not consistent) the restore is done even if the error occurs. The procedure: create proc usp_restore_databases ( @source_directory varchar(1000), @restore_directory varchar(1000) ) as begin declare @number_of_backup_files int -- begin transaction -- begin try -- step 0: Initial validation if(right(@source_directory, 1) <> '\') set @source_directory = @source_directory + '\' if(right(@restore_directory, 1) <> '\') set @restore_directory = @restore_directory + '\' -- step 1: Put all the backup files in the specified directory in a table -- declare @backup_files table ( file_path varchar(1000)) declare @dos_command varchar(1000) set @dos_command = 'dir ' + '"' + @source_directory + '*.bak" /s/b' /* DEBUG */ print @dos_command insert into @backup_files(file_path) exec xp_cmdshell @dos_command delete from @backup_files where file_path IS NULL select @number_of_backup_files = count(1) from @backup_files /* DEBUG */ select * from @backup_files /* DEBUG */ print @number_of_backup_files -- step 2: restore each backup file -- declare backup_file_cursor cursor for select file_path from @backup_files open backup_file_cursor declare @index int; set @index = 0 while(@index < @number_of_backup_files) begin declare @backup_file_path varchar(1000) fetch next from backup_file_cursor into @backup_file_path /* DEBUG */ print @backup_file_path -- step 2a: parse the full backup file name to get the DB file name. declare @db_name varchar(100) set @db_name = right(@backup_file_path, charindex('\', reverse(@backup_file_path)) -1) -- still has the .bak extension /* DEBUG */ print @db_name set @db_name = left(@db_name, charindex('.', @db_name) -1) /* DEBUG */ print @db_name set @db_name = lower(@db_name) /* DEBUG */ print @db_name -- step 2b: find out the logical names of the mdf and ldf files declare @mdf_logical_name varchar(100), @ldf_logical_name varchar(100) declare @backup_file_contents table ( LogicalName nvarchar(128), PhysicalName nvarchar(260), [Type] char(1), FileGroupName nvarchar(128), [Size] numeric(20,0), [MaxSize] numeric(20,0), FileID bigint, CreateLSN numeric(25,0), DropLSN numeric(25,0) NULL, UniqueID uniqueidentifier, ReadOnlyLSN numeric(25,0) NULL, ReadWriteLSN numeric(25,0) NULL, BackupSizeInBytes bigint, SourceBlockSize int, FileGroupID int, LogGroupGUID uniqueidentifier NULL, DifferentialBaseLSN numeric(25,0) NULL, DifferentialBaseGUID uniqueidentifier, IsReadOnly bit, IsPresent bit ) insert into @backup_file_contents exec ('restore filelistonly from disk=' + '''' + @backup_file_path + '''') select @mdf_logical_name = LogicalName from @backup_file_contents where [Type] = 'D' select @ldf_logical_name = LogicalName from @backup_file_contents where [Type] = 'L' /* DEBUG */ print @mdf_logical_name + ', ' + @ldf_logical_name -- step 2c: restore declare @mdf_file_name varchar(1000), @ldf_file_name varchar(1000) set @mdf_file_name = @restore_directory + @db_name + '.mdf' set @ldf_file_name = @restore_directory + @db_name + '.ldf' /* DEBUG */ print 'mdf_logical_name = ' + @mdf_logical_name + '|' + 'ldf_logical_name = ' + @ldf_logical_name + '|' + 'db_name = ' + @db_name + '|' + 'backup_file_path = ' + @backup_file_path + '|' + 'restore_directory = ' + @restore_directory + '|' + 'mdf_file_name = ' + @mdf_file_name + '|' + 'ldf_file_name = ' + @ldf_file_name restore database @db_name from disk = @backup_file_path with move @mdf_logical_name to @mdf_file_name, move @ldf_logical_name to @ldf_file_name -- step 2d: iterate set @index = @index + 1 end close backup_file_cursor deallocate backup_file_cursor -- end try -- begin catch -- print error_message() -- rollback transaction -- return -- end catch -- -- commit transaction end Does anybody have any ideas why this might be happening? Another question: is the transaction code useful ? i.e., if there are 2 databases to be restored, will SQL Server undo the restore of one database if the second restore fails?

  • Compound dictionary keys
