  • Multiple instances of the same Async task (Windows Phone)

    - by Bart Teunissen
    After googeling for ages, and reading some stuff about async task in books. I made a my first program with an async task in it. Only to find out, that i can only start one task. I want to run the task more then once. This is where i found out that that doesn't seem to work. to be a little bit clearer, here are some parts of my code: InitFunction(var); This is the Task itself public async Task InitFunction(string var) { _VarHandle = await _AdsClient.GetSymhandleByNameAsync(var); _Data = await _AdsClient.ReadAsync<T>(_VarHandle); _AdsClient.AddNotificationAsync<T>(_VarHandle, AdsTransmissionMode.OnChange, 1000, this); } This works like a charm when i execute the task only once.. But is there a possibility to run it multiple times. Something like this? InitFunction(var1); InitFunction(var2); InitFunction(var3); Because if i do this now (multiple tasks at once), the task it wants to start is still running, and it throws an exeption. if someone could help me with this, that would be awesome! ~ Bart

  • Problem connecting to postgres with Kohana 3 database module on OS X Snow Leopard

    - by Bart Gottschalk
    Environment: Mac OS X 10.6 Snow Leopard PHP 5.3 Kohana 3.0.4 When I try to configure and use a connection to a postgresql database on localhost I get the following error: ErrorException [ Warning ]: mysql_connect(): [2002] No such file or directory (trying to connect via unix:///var/mysql/mysql.sock) Here is the configuration of the database in /modules/database/config/database.php (note the third instance named 'pgsqltest') return array ( 'default' => array ( 'type' => 'mysql', 'connection' => array( /** * The following options are available for MySQL: * * string hostname * string username * string password * boolean persistent * string database * * Ports and sockets may be appended to the hostname. */ 'hostname' => 'localhost', 'username' => FALSE, 'password' => FALSE, 'persistent' => FALSE, 'database' => 'kohana', ), 'table_prefix' => '', 'charset' => 'utf8', 'caching' => FALSE, 'profiling' => TRUE, ), 'alternate' => array( 'type' => 'pdo', 'connection' => array( /** * The following options are available for PDO: * * string dsn * string username * string password * boolean persistent * string identifier */ 'dsn' => 'mysql:host=localhost;dbname=kohana', 'username' => 'root', 'password' => 'r00tdb', 'persistent' => FALSE, ), 'table_prefix' => '', 'charset' => 'utf8', 'caching' => FALSE, 'profiling' => TRUE, ), 'pgsqltest' => array( 'type' => 'pdo', 'connection' => array( /** * The following options are available for PDO: * * string dsn * string username * string password * boolean persistent * string identifier */ 'dsn' => 'mysql:host=localhost;dbname=pgsqltest', 'username' => 'postgres', 'password' => 'dev1234', 'persistent' => FALSE, ), 'table_prefix' => '', 'charset' => 'utf8', 'caching' => FALSE, 'profiling' => TRUE, ), ); And here is the code to create the database instance, create a query and execute the query: $pgsqltest_db = Database::instance('pgsqltest'); $query = DB::query(Database::SELECT, 'SELECT * FROM test')->execute(); I'm continuing to research a solution for this error but thought I'd ask to see if someone else has already found a solution. Any ideas are welcome. One other note is that I know my build of PHP can access this postgresql db since I'm able to manage the db using phpPgAdmin. But I have yet to determine what phpPgAdmin is doing differently to connect to the db than what Kohana 3 is attempting. Bart

  • In WPF, Selecting ItemContainerStyle based on data bound content

    - by Bart Roozendaal
    In #WPF you have ItemTemplateSelectors. But, can you also select an ItemContainerStyle based on the datatype of a bound object? I am databinding a scatterview. I want to set some properties of the generated ScatterViewItems based on the object in their DataContext. A mechanism similar to ItemTemplateSelector for styles would be great. Is that at all possible? I am now binding to properties in the objects that I am displaying to get the effect, but that feels like overhead and too complex (and most importantly, something that our XU designers can't do by themselves). This is the XAML that I am using now. Your help is greatly appreciated. <s:ScatterView x:Name="topicsViewer"> <s:ScatterView.ItemTemplateSelector> <local:TopicViewerDataTemplateSelector> <DataTemplate DataType="{x:Type mvc:S7VideoTopic}"> <Grid> <ContentPresenter Content="{Binding MediaElement}" /> <s:SurfaceButton Visibility="{Binding MailToVisible}" x:Name="mailto" Tag="{Binding Titel}" Click="mailto_Click" HorizontalAlignment="Right" VerticalAlignment="Top" Background="Transparent" Width="62" Height="36"> <Image Source="/Resources/MailTo.png" /> </s:SurfaceButton> <StackPanel Orientation="Horizontal" VerticalAlignment="Bottom" HorizontalAlignment="Center" Height="32"> <s:SurfaceButton Tag="{Binding MediaElement}" x:Name="btnPlay" Click="btnPlay_Click"> <Image Source="/Resources/control_play.png" /> </s:SurfaceButton> <s:SurfaceButton Tag="{Binding MediaElement}" x:Name="btnPause" Click="btnPause_Click"> <Image Source="/Resources/control_pause.png" /> </s:SurfaceButton> <s:SurfaceButton Tag="{Binding MediaElement}" x:Name="btnStop" Click="btnStop_Click"> <Image Source="/Resources/control_stop.png" /> </s:SurfaceButton> </StackPanel> </Grid> </DataTemplate> <DataTemplate DataType="{x:Type mvc:S7ImageTopic}"> <Grid> <ContentPresenter Content="{Binding Resource}" /> <s:SurfaceButton Visibility="{Binding MailToVisible}" x:Name="mailto" Tag="{Binding Titel}" Click="mailto_Click" HorizontalAlignment="Right" VerticalAlignment="Top" Background="Transparent" Width="62" Height="36"> <Image Source="/Resources/MailTo.png" /> </s:SurfaceButton> </Grid> </DataTemplate> <DataTemplate DataType="{x:Type local:Kassa}"> <ContentPresenter Content="{Binding}" Width="300" Height="355" /> </DataTemplate> </local:TopicViewerDataTemplateSelector> </s:ScatterView.ItemTemplateSelector> <s:ScatterView.ItemContainerStyle> <Style TargetType="s:ScatterViewItem"> <Setter Property="MinWidth" Value="200" /> <Setter Property="MinHeight" Value="150" /> <Setter Property="MaxWidth" Value="800" /> <Setter Property="MaxHeight" Value="700" /> <Setter Property="Width" Value="{Binding DefaultWidth}" /> <Setter Property="Height" Value="{Binding DefaultHeight}" /> <Setter Property="s:ScatterViewItem.CanMove" Value="{Binding CanMove}" /> <Setter Property="s:ScatterViewItem.CanScale" Value="{Binding CanScale}" /> <Setter Property="s:ScatterViewItem.CanRotate" Value="{Binding CanRotate}" /> <Setter Property="Background" Value="Transparent" /> </Style> </s:ScatterView.ItemContainerStyle> </s:ScatterView> Bart Roozendaal, Sevensteps

  • How to resize image to fit UITableView cell?

    - by stefanB
    How to fit UIImage into the cell of UITableView, UITableViewCell (?). Do you addSubview to cell or is there a way to resize cell.image or the UIImage before it is assigned to cell.image ? I want to keep the cell size default (whatever it is when you init with zero rectangle) and would like to add icon like pictures to each entry. Images are slightly bigger than the cell size (table row size). I think the code looks like this (from top of my head): UIImage * image = [[UIImage alloc] imageWithName:@"bart.jpg"]; cell = ... dequeue cell in UITableView data source (UITableViewController ...) cell.text = @"bart"; cell.image = image; What do I need to do to resize the image to fit the cell size? I've seen something like: UIImageView * iview = [[UIImageView alloc] initWithImage:image]; iview.frame = CGRectMake(...); // or something similar [cell.contentView addSubview:iview] The above will add image to cell and I can calculate the size to fit it, however: I'm not sure if there is a better way, isn't it too much overhead to add UIImageView just to resize the cell.image ? Now my label (cell.text) needs to be moved as it is obscured by image, I've seen a solution where you just add the text as a label: Example: UILabel * text = [[UILable alloc] init]; text.text = @"bart"; [cell.contentView addSubview:iview]; [cell.contentView addSubview:label]; // not sure if this will position the text next to the label // edited original example had [cell addSubview:label], maybe that's the problem Could someone point me in correct direction? EDIT: Doh [cell.contentview addSubview:view] not [cell addSubview:view] maybe I'm supposed to look at this: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = ...; CGRect frame = cell.contentView.bounds; UILabel *myLabel = [[UILabel alloc] initWithFrame:frame]; myLabel.text = ...; [cell.contentView addSubview:myLabel]; [myLabel release]; }

  • How should I host a site that could potentially get a short spike in traffic of 1000%+

    - by James Simpson
    This is a purely theoretical question, but what if I had a site that would normally only get a couple thousand hits a day, but for a few days each month that could shoot to several hundred thousand or even several million hits over the period of 1-3 days. The site would be pretty bare-bones (as in, 2-3 total pages with 1-2 max MySQL queries on each page and some PHP), so bandwidth wouldn't be the issue, but sheer volume taking down the site would be the main concern. Cloud hosting seems like the best way to go, but would something like Amazon EC2, MediaTemple, or something else be the right choice in this case?

  • Office communicator voice chat

    - by Gareth Simpson
    My company recently mandated a switch from Skype to Office Communicator for IM / voice chat. While Skype was never the be all and end all of VOIP, it was at least usable. With Communicator, if one person is talking, everyone else is basically silent (or as good as) so a normal conversation is impossible. No one can interrupt anyone else, if two people start talking at once it's a crap shoot who gets to be heard and often the person who is inaudible doesn't know it. There do not seem to be any client side settings to fix this. Is there anything that can be done server side or is it just rubbish?

  • What are some good, free tools to run automated security audits for PHP code?

    - by James Simpson
    I've been looking for some time now and have come up short. The most promising I found was Spike PHP, which seems to no longer work. I'm looking to scan my code for potential risks of SQL Injection, XSS, etc. I've gone through most of my code manually, but with a few hundred thousand lines of code, I'm sure I missed things. If possible, are there any tools that can be downloaded and analyze code on my local machine rather than installing to the live server (this isn't a requirement if not)?

  • Setting page parent to a private page in Wordpress 2.8

    - by Gareth Simpson
    I have a site developed in Wordpress 2.7 that makes extensive use of private pages as the parents of public pages. The private pages are never meant to be seen, they are just there to act as containers for the other pages. Since upgrading to Wordpress 2.8, it seems this isn't possible any more. Private pages no long show up in the drop box of pages I can use as a parent, and if I edit a page with a private parent, it loses the parenting information. Is there anything I can do about this?

  • Linux (Kubuntu 9.10): Strange DNS problem [seems to be IPv6 issue]

    - by Homer J. Simpson
    Hi, I'm experiencing strange problems with my Kubuntu 9.10 when doing DNS requests from various applications. The requests are extremely slow, so loading any pages in Firefox or Konqueror, doing package installations in Kpackagemanager and other apps is really painful, while for example Opera doesnt have any problems, and ping is normally fast as well for DNS pings. I checked the proxy settings of both the used applications as well as of the general system and there are none, so to me it doesn't seem as there was something inbetween.. Does anybody have an idea on what to check for possible problem sources or how to solve this ? I'm behind a DSL home router which does the DHCP (and works well with my other computer). Any kind of advice would be really helpful. Edit: It seems to be some kind of IPv6 problem, as I could get it to work by disabling IPv6 explicitly in Firefox. Is there a general solution to this ?

  • Lighttpd as a proxy to a https host

    - by Homer J. Simpson
    Hi, I am trying to set up a lighttpd as proxy from one server to another (which is running Apache/SSL), having trouble with the https part.. I want to be able to capture https requests and let the Apache server handle it, trying this: $SERVER["socket"] == ":443" { $HTTP["host"] == "www.mydomain.com" { proxy.server = ( "" => ( ( "host" => "123.123.123.123", # the Apache "port" => 443))) } } Normal port 80 requests are working fine.. What am I doing wrong ? Edit: Additionaly, error.log doesnt show anything.. Requests to https://www.mydomain.com are not finishing.

  • Printing fails after first print with Centos 6 and HP LaserJet P3015dn printer

    - by Gavin Simpson
    Centos 6 recognises and configures a HP LaserJet P3015dn printer connected via USB. This machine is being configured as a small group file/print server.

I checked the proxy settings of both the used applications as well as of the general system and there are none, so to me it doesn't seem as there was something inbetween.. Does anybody have an idea on what to check for possible problem sources or how to solve this ? I'm behind a DSL home router which does the DHCP (and works well with my other computer). Any kind of advice would be really helpful. Edit: It seems to be some kind of IPv6 problem, as I could get it to work by disabling IPv6 explicitly in Firefox. Is there a general solution to this ?

  • Viewpoint gem and Exchange resource account

    - by scott.simpson
    Hi- I'm trying my hand at using the Viewpoint gem (by zenchild @ github) as the base for a meeting scheduling system. It's great at reading calendar information from regular Exchange 2007 accounts, but I got stuck trying to change the SOAP request header to allow me to read resource accounts as a delegate. I came across http://blogs.msdn.com/b/mstehle/archive/2009/06/16/exchange-api-team-blog-exchange-impersonation-vs-delegate-access.aspx and it seems to be what I need, and I have the feeling I'm on the edge of getting it working, but I'm just not quite there yet as a ruby programmer. Any help would be appreciated... Thanks!

  • How to extract jpegs from a video file using ffmpeg

    - by Andrew Simpson
    I am using C# and ffmpeg. In this scenario I have 279 individual jpegs and i have used ffmpeg to create a AVI file from these images on my client. CMD Line: -f image2 -r 10 -i "C:\000EC902F17F\img%05d.jpg" -s 352x288 -y "C:\1\test.avi" I then upload to my server. CMD Line: -i c:\1\1.avi c:\1\img-%05d.jpg I then extract jpegs from the AVI file. I get 265 jpegs back. Obviously ffmpeg is dropping these frames (most probable) when the avi is 1st created. Is there a way to 'force' to encode using ALL the images I have? Thanks. PS I did not specify any command line option other than the size of the video output. As far as I am aware if none are specified then ffmpeg automatically chooses the best ones?

  • Is this a valid backup strategy for MongoDB?

    - by James Simpson
    I've got a single dedicated server with a MongoDB database of around 10GB. I need to do daily backups, but I can't have downtime with the database. Is it possible to use a replica set on a single disk (with 2 instances of mongod running on different ports), and simply take the secondary one offline and backup the data files to an offsite storage such as S3 (journaling is turned on)? Or would using master/slave be better than a replica set? Is this viable, and if so, what potential problems could I have? If not, how do I conceptualize this to work?

  • What are some general tips to make InnoDB for MySQL perform at its highest?

    - by James Simpson
    I've been using MyISAM exclusively for several years now and know the ins-and-outs pretty well of how to optimize it, but I've just recently started using InnoDB for some of my tables and don't know that much about it. What are some general tips to help improve the performance of these InnoDB tables (they were converted from MyISAM and have anywhere from 100k - 2M rows and most won't use transactions).

  • Will adding extra RAM in my computer speed it up?

    - by Harry Simpson
    I have a 5 year old Dell Inspiron 530 desktop computer which is slowly grinding to a halt. Someone told me if i put extra RAM in itll speed it up. Inside the computer there are four slots for memory but only two has memory in them and they are 1GB each. if i bought another 2no. 1GB and put them in the free slots would it speed the computer up (would it be twice as fast?) and is it as simple as just putting them in or is there other things i need to do?

  • Microsoft Dev Days &ndash; Johannesburg 2010

    - by MarkPearl
    So I am half way through dev days in Johannesburg. It has been quite an interesting day… Maybe it is me, but this year it hasn’t been as OMG as at previous conferences. A few things that stood out though… 1) This is the first time I have had to queue in a line to use the gents toilets before – yes, a true sign that we are at a typically male dominated industry event in this country – the men’s toilets were jam packed – the ladies if there were any there didn’t have a problem. 2) Bart De Smet presentation still rocks – I am a fan of Bart’s and once again his presentation was great. Something that I am going to look into in more depth which I think is a new feature in .Net is called Code Contracts. 3) I have got to get into Silverlight more… I have known this for a long time and have dabbled in it for a while, but Silverlight in my opinion will become the main platform for “hosting” applications. So… 3 things so far, hopefully I get some OMG’s from the rest of the day…

  • "Simple" Text replace function

    - by YourMomzThaBomb
    I have a string which is basically a list of "words" delimited by commas. These "words" can be pretty much any character e.g. "Bart Simpson, Ex-girlfriend, dude, radical" I'm trying to use javascript, jQuery, whatever i can to replace a word based on a search string with nothing (in essence, removing the word from the list). For example, the function is defined as such: function removeWord(myString, wordToReplace) {...}; So, passing the string listed above as myString and passing "dude" as wordToReplace would return the string "Bart Simpson, Ex-girlfriend, radical" Here's the line of code I was tinkering around with...please help me figure out what's wrong with it or some alternative (better) solution:$myString.val($myString.val().replace(/wordToReplace\, /, ""));

  • Welcome to Jackstown

    - by fatherjack
    I live in a small town, the population count isn't that great but let me introduce you to some of the population. We'll start with Martin the Doc, he fixes up anything that gets poorly, so much so that he could be classed as the doctor, the vet and even the garage mechanic. He's got a reputation that he can fix anything and that hasn't been proved wrong yet. He's great friends with Brian (who gets called "Brains") the teacher who seems to have a sound understanding of any topic you care to pass his way. If he isn't sure he tells you and then goes to find out and comes back with a full answer real quick. Its good to have that sort of research capability close at hand. Brains is also great at encouraging anyone who needs a bit of support to get them up to speed and working on their jobs. Steve sees Brains regularly, that's because he is the librarian, he keeps all sorts of reading material and nowadays there's even video to watch about any topic you like. Steve keeps scouring all sorts of places to get the content that's needed and he keeps it in good order so that what ever is needed can be found quickly. He also has to make sure that old stuff gets marked as probably out of date so that anyone reading it wont get mislead. Over the road from him is Greg, he's the town crier. We don't have a newspaper here so Greg keeps us all informed of what's going on "out of town" - what new stuff we might make use of and what wont work in a small place like this. If we are interested he goes ahead and gets people in to demonstrate their products  and tell us about the details. Greg is pretty good at getting us discounts too. Now Greg's brother Ian works for the mayors office in the "waste management department" nowadays its all about the recycling but he still has to make sure that the stuff that cant be used any more gets disposed of properly. It depends on the type of waste he's dealing with that decides how it need to be treated and he has to know a lot about the different methods and when to use which ones. There are two people that keep the peace in town, Brent is the detective, investigating wrong doings and applying justice where necessary and Bart is the diplomat who smooths things over when any people have a dispute or disagreement. Brent is meticulous in his investigations and fair in the way he handles any situation he finds. Discretion is his byword. There's a rumour that Bart used to work for the United Nations but what ever his history there is no denying his ability to get apparently irreconcilable parties working together to their combined benefit. Someone who works closely with Bart is Brad, he is the translator in town. He has several languages that he can converse in but he can also explain things from someone's point of view or  and make it understandable to someone else. To keep things on the straight and narrow from a legal perspective is Ben the solicitor, making sure we all abide by the rules.Two people who make for an interesting evening's conversation if you get them together are Aaron and Grant, Aaron is the local planning inspector and Grant is an inventor of some reputation. Anything being constructed around here needs Aarons agreement. He's quite flexible in his rules though; if you can justify what you want to do with solid logic but he wont stand for any development going on without his inclusion. That gets a demolition notice and there's no argument. Grant as I mentioned is the inventor in town, if something can be improved or created then Grant is your man. He mainly works on his own but isnt averse to getting specific advice and assistance from specialist from out of town if they can help him finish his creations.There aren't too many people left for you to meet in the town, there's Rob, he's an ex professional sportsman. He played Hockey, Football, Cricket, you name it. He was in his element as goal keeper / wicket keeper and that shows in his personal life. He just goes about his business and people often don't even know that he's helped them. Really low profile, doesn't get any glory but saves people from lots of problems, even disasters on occasion. There goes Neil, he's a bit of an odd person, some people say he's gifted with special clairvoyant powers, personally I think he's got his ear to the ground and knows where to find out the important news as soon as its made public. Anyone getting a visit from Neil is best off to follow his advice though, he's usually spot on and you wont be caught by surprise if you follow his recommendations – wherever it comes from.Poor old Andrew is the last person to introduce you to. Andrew doesn't show himself too often but when he does it seems that people find a reason to blame him for their problems, whether he had anything to do with their predicament or not. In all honesty, without fail, and to his great credit, he takes it in good grace and never retaliates or gets annoyed when he's out and about.  It pays off too as its very often the case that those who were blaming him recently suddenly find they need his help and they readily forget the issues pretty rapidly.And then there's me, what do I do in town? Well, I'm just a DBA with a lot of hats. (Jackstown Pop. 1)

  • Some notes on Reflector 7

    - by CliveT
    Both Bart and I have blogged about some of the changes that we (and other members of the team) have made to .NET Reflector for version 7, including the new tabbed browsing model, the inclusion of Jason Haley's PowerCommands add-in and some improvements to decompilation such as handling iterator blocks. The intention of this blog post is to cover all of the main new features in one place, and to describe the three new editions of .NET Reflector 7. If you'd simply like to try out the latest version of the beta for yourself you can do so here. Three new editions .NET Reflector 7 will come in three new editions: .NET Reflector .NET Reflector VS .NET Reflector VSPro The first edition is just the standalone Windows application. The latter two editions include the Windows application, but also add the power of Reflector into Visual Studio so that you can save time switching tools and quickly get to the bottom of a debugging issue that involves third-party code. Let's take a look at some of the new features in each edition. Tabbed browsing .NET Reflector now has a tabbed browsing model, in which the individual tabs have independent histories. You can open a new tab to view the selected object by using CTRL+CLICK. I've found this really useful when I'm investigating a particular piece of code but then want to focus on some other methods that I find along the way. For version 7, we wanted to implement the basic idea of tabs to see whether it is something that users will find helpful. If it is something that enhances productivity, we will add more tab-based features in a future version. PowerCommands add-in We have also included Jason Haley's PowerCommands add-in as part of version 7. This add-in provides a number of useful commands, including support for opening .xap files and extracting the constituent assemblies, and a query editor that allows C# queries to be written and executed against the Reflector object model . All of the PowerCommands features can be turned on from the options menu. We will be really interested to see what people are finding useful for further integration into the main tool in the future. My personal favourite part of the PowerCommands add-in is the query editor. You can set up as many of your own queries as you like, but we provide 25 to get you started. These do useful things like listing all extension methods in a given assembly, and displaying other lower-level information, such as the number of times that a given method uses the box IL instruction. These queries can be extracted and then executed from the 'Run Query' context menu within the assembly explorer. Moreover, the queries can be loaded, modified, and saved using the built-in editor, allowing very specific user customization and sharing of queries. The PowerCommands add-in contains many other useful utilities. For example, you can open an item using an external application, work with enumeration bit flags, or generate assembly binding redirect files. You can see Bart's earlier post for a more complete list. .NET Reflector VS .NET Reflector VS adds a brand new Reflector object browser into Visual Studio to save you time opening .NET Reflector separately and browsing for an object. A 'Decompile and Explore' option is also added to the context menu of references in the Solution Explorer, so you don't need to leave Visual Studio to look through decompiled code. We've also added some simple navigation features to allow you to move through the decompiled code as quickly and easily as you can in .NET Reflector. When this is selected, the add-in decompiles the given assembly, Once the decompilation has finished, a clone of the Reflector assembly explorer can be used inside Visual Studio. When Reflector generates the source code, it records the location information. You can therefore navigate from the source file to other decompiled source using the 'Go To Definition' context menu item. This then takes you to the definition in another decompiled assembly. .NET Reflector VSPro .NET Reflector VSPro builds on the features in .NET Reflector VS to add the ability to debug any source code you decompile. When you decompile with .NET Reflector VSPro, a matching .pdb is generated, so you can use Visual Studio to debug the source code as if it were part of the project. You can now use all the standard debugging techniques that you are used to in the Visual Studio debugger, and step through decompiled code as if it were your own. Again, you can select assemblies for decompilation. They are then decompiled. And then you can debug as if they were one of your own source code files. The future of .NET Reflector As I have mentioned throughout this post, most of the new features in version 7 are exploratory steps and we will be watching feedback closely. Although we don't want to speculate now about any other new features or bugs that will or won't be fixed in the next few versions of .NET Reflector, Bart has mentioned in a previous post that there are lots of improvements we intend to make. We plan to do this with great care and without taking anything away from the simplicity of the core product. User experience is something that we pride ourselves on at Red Gate, and it is clear that Reflector is still a long way off our usual standards. We plan for the next few versions of Reflector to be worked on by some of our top usability specialists who have been involved with our other market-leading products such as the ANTS Profilers and SQL Compare. I re-iterate the need for the really great simple mode in .NET Reflector to remain intact regardless of any other improvements we are planning to make. I really hope that you enjoy using some of the new features in version 7 and that Reflector continues to be your favourite .NET development tool for a long time to come.
