• al32utf8 in oracle and SQL Server and DB2 pulling data

  - by Bob

  I have a non-utf8 oracle database running on 11.1.0.7. We need to support greek characters. So we have two options: use nvarchar, nclob fields for those fields that need greek (it is not all fields). We have tested this and gotten it to work with java coding. convert Oracle to AL32UTF8 database. I am not asking how to do this. I got this from the Oracle Site/Oracle Support. I know what is involved, lossy data, etc, increasing the size of the database. My question is we have users to our system that connect to our database with database links but work on SQL Server and IBM DB2 databases. I do not have access to those databases and I do not have experience with them. If they are not in UTF-8 databases what happens when they pull UTF8 data? I would assume that English/Ascii characters are fine and the greek will end up as junk data. I also ran Oracle Character set scanner (oracle command line utility you use to get info about the affects of a character set conversion). It says that my database will crease in sizez by about 20%. Does this have an affect on users with 3rd party databases? These are customers of our data and there is a limit to how much access I can have to them to run tests. Any information you have would be welcome.

• Fossil gpg workflow for teams

  - by Alex_coder

  I'm learning fossil and trying to reproduce a workflow for two people modifying the same source code tree. So, Alice and Bob both have local repositories of some source code. Both have autosync off. Alice hacks some more, does some commits signing check-ins with her gpg key. This part is fine, as Alice I've managed to generate gpg keys, fossil asked me the key password when commiting. I'm also aware of gpg-agent but don't use it yet, because I'm trying to keep things as simple as possible for now. Now, at some point Bob pulls changes from Alice's fossil repo. How would he verify Alice's signed check-ins?

• How to produce precisely-timed tone and silence?

  - by Bob Denny

  I have a C# project that plays Morse code for RSS feeds. I write it using Managed DirectX, only to discover that Managed DirectX is old and deprecated. The task I have is to play pure sine wave bursts interspersed with silence periods (the code) which are precisely timed as to their duration. I need to be able to call a function which plays a pure tone for so many milliseconds, then Thread.Sleep() then play another, etc. At its fastest, the tones and spaces can be as short as 40ms. It's working quite well in Managed DirectX. To get the precisely timed tone I create 1 sec. of sine wave into a secondary buffer, then to play a tone of a certain duration I seek forward to within x milliseconds of the end of the buffer then play. I've tried System.Media.SoundPlayer. It's a loser because you have to Play(), Sleep(), then Stop() for arbitrary tone lengths. The result is a tone that is too long, variable by CPU load. It takes an indeterminate amount of time to actually stop the tone. I then embarked on a lengthy attempt to use NAudio 1.3. I ended up with a memory resident stream providing the tone data, and again seeking forward leaving the desired length of tone remaining in the stream, then playing. This worked OK on the DirectSoundOut class for a while (see below) but the WaveOut class quickly dies with an internal assert saying that buffers are still on the queue despite PlayerStopped = true. This is odd since I play to the end then put a wait of the same duration between the end of the tone and the start of the next. You'd think that 80ms after starting Play of a 40 ms tone that it wouldn't have buffers on the queue. DirectSoundOut works well for a while, but its problem is that for every tone burst Play() it spins off a separate thread. Eventually (5 min or so) it just stops working. You can see thread after thread after thread exiting in the Output window while running the project in VS2008 IDE. I don't create new objects during playing, I just Seek() the tone stream then call Play() over and over, so I don't think it's a problem with orphaned buffers/whatever piling up till it's choked. I'm out of patience on this one, so I'm asking in the hopes that someone here has faced a similar requirement and can steer me in a direction with a likely solution.

• enclosing double quotes in array

  - by Jared

  Hi all I might be looking at this the wrong way, but I have a form that does its thing (sends emails etc etc) but I also put in some code to make a simple flatfile csv log with some of the user entered details. If a user accidentally puts in for instance 'himynameis","bob' this would either break the csv row (because the quotes weren't encapsulated) or if I use htmlspecialchars() and stripslashes() on the data, I end up with a ugly data value of 'himynameis&quot;,&quot;bob'. My question is, how can I handle the incoming data to cater for '"' being put in the form without breaking my csv file? this is my code for creating the csv log file. @$name = htmlspecialchars(trim($_POST['name'])); @$emailCheck = htmlspecialchars(trim($_POST['email'])); @$title = htmlspecialchars(trim($_POST['title'])); @$phone = htmlspecialchars(trim($_POST['phone'])); function logFile($logText) { $path = 'D:\logs'; $filename = '\Log-' . date('Ym', time()) . '.csv'; $file = $path . $filename; if(!file_exists($file)) { $logHeader = array('Date', 'IP_Address', 'Title', 'Name', 'Customer_Email', 'Customer_Phone', 'file'); $fp = fopen($file, 'a'); fputcsv($fp, $line); } $fp = fopen($file, 'a'); foreach ($logText as $record) { fputcsv($fp, $record); } } //Log submission to file $date = date("Y/m/d H:i:s"); $clientIp = getIpAddress(); //get clients IP address $nameLog = stripslashes($name); $titleLog = stripslashes($title); if($_FILES['uploadedfile']['error'] == 4) $filename = "No file attached."; //check if file uploaded and return $logText = array(array("$date", "$clientIp", "$titleLog", "$nameLog", "$emailCheck", "$phone", "$filename")); logFile($logText); //write form details to log Here is a sample of the incoming array data: Array ( [0] => Array ( [0] => 2010/05/17 10:22:27 [1] => xxx.xxx.xxx.xxx [2] => title [3] => """"himynameis","bob" [4] => [email protected] [5] => 346346 [6] => No file attached. ) ) TIA Jared

• Limiting the Amount of Tags for Acts as Taggable On

  - by bob

  Hello, I am wondering how to limit the amount of tags, the tag_cloud function returns for this plugin. http://github.com/collectiveidea/acts-as-taggable-on Also, I would like to know how to order it so that it orders the tags by the highest count. So the most popular are at the top. I tried to do @tags = Post.tag_counts_on(:tags, :limit = 5) but that did not work. Controller: class PostController < ApplicationController def tag_cloud @tags = Post.tag_counts_on(:tags) end end View: <% tag_cloud @tags, %w(css1 css2 css3 css4) do |tag, css_class| %> <%= link_to tag.name, { :action => :tag, :id => tag.name }, :class => css_class %> <% end %> Thanks!

• Java resource closing

  - by Bob

  Hi, I'm writing an app that connect to a website and read one line from it. I do it like this: try{ URLConnection connection = new URL("www.example.com").openConnection(); BufferedReader rd = new BufferedReader(new InputStreamReader(connection.getInputStream())); String response = rd.readLine(); rd.close(); }catch (Exception e) { //exception handling } Is it good? I mean, I close the BufferedReader in the last line, but I do not close the InputStreamReader. Should I create a standalone InputStreamReader from the connection.getInputStream, and a BufferedReader from the standalone InputStreamReader, than close all the two readers? I think it will be better to place the closing methods in the finally block like this: InputStreamReader isr = null; BufferedReader br = null; try{ URLConnection connection = new URL("www.example.com").openConnection(); isr = new InputStreamReader(connection.getInputStream()); br = new BufferedReader(isr); String response = br.readLine(); }catch (Exception e) { //exception handling }finally{ br.close(); isr.close(); } But it is ugly, because the closing methods can throw exception, so I have to handle or throw it. Which solution is better? Or what would be the best solution?

• JQuery: Dynamically-generated form fields not submitted and event handlers appear to fire multiple t

  - by Bob

  Hi, I'm new to JQuery, so I apologise if there's something which should be obvious which I'm unaware of. I seem to be having a couple of issues some JQuery I'm trying to implement: Code: http://pastebin.ca/1843496 (the editor didn't seem to like HTML tags) post_test.php simply contains: [?php print_r($_POST); ?] in an attempt to find out what's actually being submitted. The first issue I'm having is that only the hidden form fields are actually being submitted. If I insert tags into the container DIV manually it works as expected, but when done as above the text field doesn't get posted. From what I've read, I gather it's to do with the fact that the DOM is being modified after it's loaded, but the thing that's puzzling me is why, in that case, there are no issues referencing the other added hidden fields or the tag. I've experimented with changing the event handler for a.save to '.live('click', function ...' and also using LiveQuery to no avail. The other issue is that when a.save is clicked, before the form is actually submitted, as far as I can tell the event handler is running again, replacing the value entered into the text field with the value of editable.text(), which is what ultimately gets submitted. I'm sorry if any of this is unclear. Regards,

• How do I change the CellErrorStyle for an Xceed Datagrid?

  - by Bob

  So in the Xceed documentation there is a code example that does not work for me. It may be because my grid is bound to a DataGridCollectionView. The objects in the collection used by the datagridcollection are what implement IDataErrorInfo. The errors are showing up just fine. The problem is that they are using the default orange background for errors...I need a red border. Below is the XAML instantiation of my grid. I set the DataCell background property to red just so I could be sure I had access to the grid's properties... I do. I just can't find the way to identify the cell's w/ errors so I can style them. Thanks! <XceedDG:DataGridControl Grid.Row="1" Grid.ColumnSpan="5" ItemsSource="{Binding Path = ABGDataGridCollectionView, UpdateSourceTrigger=PropertyChanged}" Background="{x:Static Views:DataGridControlBackgroundBrushes.ElementalBlue}" IsDeleteCommandEnabled="True" FontSize="16" AutoCreateColumns="False" x:Name="EncounterDataGrid" AllowDrop="True"> <XceedDG:DataGridControl.View> <Views:TableView ColumnStretchMode="All" ShowRowSelectorPane="True" ColumnStretchMinWidth="100"> <Views:TableView.FixedHeaders> <DataTemplate> <XceedDG:InsertionRow Height="40"/> </DataTemplate> </Views:TableView.FixedHeaders> </Views:TableView> </XceedDG:DataGridControl.View> <!--Group Header formatting--> <XceedDG:DataGridControl.Resources> <Style TargetType="{x:Type XceedDG:GroupByControl}"> <Setter Property="Visibility" Value="Collapsed"/> </Style> <Style TargetType="{x:Type XceedDG:DataCell}"> <Setter Property="Background" Value="Red"/> </Style> </XceedDG:DataGridControl.Resources> ...

• Finding duplicate values in a SQL table - ADVANCED

  - by Alex

  It's easy to find duplicates with one field SELECT name, COUNT(email) FROM users GROUP BY email HAVING ( COUNT(email) > 1 ) So if we have a table ID NAME EMAIL 1 John [email protected] 2 Sam [email protected] 3 Tom [email protected] 4 Bob [email protected] 5 Tom [email protected] This query will give us John, Sam, Tom, Tom because they all have the same e-mails. But what I want, is to get duplicates with the same e-mails and names. I want to get Tom, Tom. I made a mistake, and allowed to insert duplicate name and e-mail values. Now I need to remove/change the duplicates. But I need to find them first.

• What are appropriate ways to represent relationships between people in a database table?

  - by Emilio

  I've got a table of people - an ID primary key and a name. In my application, people can have 0 or more real-world relationships with other people, so Jack might "work for" Jane and Tom might "replace" Tony and Bob might "be an employee of" Rob and Bob might also "be married to" Mary. What's the best way to represent this in the database? A many to many intersect table? A series of self joins? A relationship table with one row per relationship pair and type, where I insert records for the relationship in both directions?

  - by Xaqron

  I have a simple table "Employees" with this fields: ID, ParentID, Name ParentID is Nullable since an employee may have no Manager. This table has a one-to-many relationship with itself: ID --one--to--many--> ParentID Now I want a query which returns this columns: Name, Count of rows where their ParentID equals to the current row ID (the row is the manager of that rows) Sample Table: ID | ParentID | Name ====================== 1 | 0 | John ---------------------- 2 | 1 | Bob ---------------------- 3 | 1 | Alice ---------------------- 4 | 3 | Jack This way I can find an employee is the manager of how many other employees.

• Play .WAV under Mono on Mac OS X (Snow Leopard)?

  The Mono 2.6 distribution contains System.Media.SoundPlayer, but attempts to play result in no sound (and no errors) on Mac OS X. All I can find with Google search is obscure references to ALSA. I posted to the Mono-OSX list, but there have been on replies there. I hope someone here has an answer. I think I need to tap into CoreAudio, but don't know how from Mono/C#.

• Regex for extracting second level domain from FQDN?

  - by Bob

  I can't figure this out. I need to extract the second level domain from a FQDN. For example, all of these need to return "example.com": example.com foo.example.com bar.foo.example.com example.com:8080 foo.example.com:8080 bar.foo.example.com:8080 Here's what I have so far: Dim host = Request.Headers("Host") Dim pattern As String = "(?<hostname>(\w+)).(?<domainname>(\w+.\w+))" Dim theMatch = Regex.Match(host, pattern) ViewData("Message") = "Domain is: " + theMatch.Groups("domainname").ToString It fails for example.com:8080 and bar.foo.example.com:8080. Any ideas?

• NSOutlineView with Drag and Drop

  - by bob

  I read the other post here on Outlineviews and DND, but I can't get my program to work. At the bottom of this post is a link to a zip of my project. Its very basic with only an outlineview and button. I want it to receive text files being dropped on it, but something is wrong with my code or connections. I tried following Apple's example code of their NSOutline Drag and Drop, but I'm missing something. 1 difference is my program is a document based program and their example isn't. I set the File's Owner to receive delegate actions, since that's where my code to handle drag and drop is, as well as a button action. Its probably a simple mistake, so could someone please look at it and tell me what I'm doing wrong? Here is a link to the file: http://www.4shared.com/file/or1A7aHk/OutlineDragDrop.html

• FingerPrint Reader SDK or API

Most of the SDKs out there do much more than this and require expensive licensing which I don't want. I will be integrating this into a .NET windows application. One requirement, it needs to work with a Futronics FS80 which is a very popular fingerprint reader. Any suggestions?

• Custom Build Step Paths Between x86 and x64 in Visual Studio

  - by Bob Somers

  For reference, I'm using Visual Studio 2010. I have a custom build step defined as follows: if exist "$(TargetDir)"server.dll copy "$(TargetDir)"server.dll "c:\program files (x86)\myapp\server.dll" This works great on my desktop, which is running 64-bit Windows. However, when I build on my laptop, c:\Program Files (x86)\ doesn't exist because it's running 32-bit Windows. I'd like to put in something that will work between both editions of Windows, since the project files are under version control and it's a real pain to change the paths every time I work on my laptop. If this were a *nix environment I'd just create a symlink and be done with it. Any ideas?
