• Tips on managing dependencies for a release?

  - by Andrew Murray

  Our system comprises many .NET websites, class libraries, and a MSSQL database. We use SVN for source control and TeamCity to automatically build to a Test server. Our team is normally working on 4 or 5 projects at a time. We try to lump many changes into a largish rollout every 2-4 weeks. My problem is with keeping track of all the dependencies for a rollout. Example: Website A cannot go live until we've rolled out Branch X of Class library B, built in turn against the Trunk of Class library C, which needs Config Updates Y and Z and Database Update D, which needs Migration Script E... It gets even more complex - like making sure each developer's project is actually compatible with the others and are building against the same versions. Yes, this is a management issue as much as a technical issue. Currently our non-optimal solution is: a whiteboard listing features that haven't gone live yet relying on our memory and intuition when planning the rollout, until we're pretty sure we've thought of everything... a dry-run on our Staging environment. It's a good indication but we're often not sure if Staging is 100% in sync with Live - part of the problem I'm hoping to solve. some amount of winging it on rollout day. So far so good, minus a few close calls. But as our system grows, I'd like a more scientific release management system allowing for more flexibility, like being able to roll out a single change or bugfix on it's own, safe in the knowledge that it won't break anything else. I'm guessing the best solution involves some sort of version numbering system, and perhaps using a project management tool. We're a start-up, so we're not too hot on religiously sticking to rigid processes, but we're happy to start, providing it doesn't add more overhead than it's worth. I'd love to hear advice from other teams who have solved this problem.

• Can memory be cleaned up?

  - by Tom

  I am working in Delphi 5 (with FastMM installed) on a Win32 project, and have recently been trying to drastically reduce the memory usage in this application. So far, I have cut the usage nearly in half, but noticed something when working on a separate task. When I minimized the application, the memory usage shrunk from 45 megs down to 1 meg, which I attributed to it paging out to disk. When I restored it and restarted working, the memory went up only to 15 megs. As I continued working, the memory usage slowly went up again, and a minimize and restore flushed it back down to 15 megs. So to my thinking, when my code tells the system to release the memory, it is still being held on to according to Windows, and the actual garbage collection doesn't kick in until a lot later. Can anyone confirm/deny this sort of behavior? Is it possible to get the memory cleaned up programatically? If I keep using the program without doing this manual flush, I get an out of memory error after a while, and would like to eliminate that. Thanks.

• AutoMapper and flattening nested arrays

  - by Bryan Slatner

  I'm trying to use AutoMapper to flatten multiple levels of arrays. Consider the following source classes: class X { public string A { get; set; } public Y[] B { get; set; } } class Y { public string C { get; set; } public Z[] D { get; set; } } class Z { public string E { get; set; } public string F { get; set; } } And the following destination: class Destination { public string A { get; set; } public string C { get; set; } public string E { get; set; } public string F { get; set; } } What I'd like to be able to do is get a List from one or more X, e.g.: Mapper.Map<IEnumerable<X>, IEnumerable<Destination>>(arrayOfX); I'm unable to figure out what sort of mapping configuration to use to achieve this. MapFrom seems like the way to go for 1:1 compositions, but doesn't seem to be able to handle the array (or other enumerable) unless I use AutoMapper's destination naming convention. Any insights on how to achieve this?

• Rails model relations depending on count of nested relations

  - by Lowgain

  I am putting together a messaging system for a rails app I am working on. I am building it in a similar fashion to facebook's system, so messages are grouped into threads, etc. My related models are: MsgThread - main container of a thread Message - each message/reply in thread Recipience - ties to user to define which users should subscribe to this thread Read - determines whether or not a user has read a specific message My relationships look like class User < ActiveRecord::Base #stuff... has_many :msg_threads, :foreign_key => 'originator_id' #threads the user has started has_many :recipiences has_many :subscribed_threads, :through => :recipiences, :source => :msg_thread #threads the user is subscribed to end class MsgThread < ActiveRecord::Base has_many :messages has_many :recipiences belongs_to :originator, :class_name => "User", :foreign_key => "originator_id" end class Recipience < ActiveRecord::Base belongs_to :user belongs_to :msg_thread end class Message < ActiveRecord::Base belongs_to :msg_thread belongs_to :author, :class_name => "User", :foreign_key => "author_id" end class Read < ActiveRecord::Base belongs_to :user belongs_to :message end I'd like to create a new selector in the user sort of like: has_many :updated_threads, :through => :recipiencies, :source => :msg_thread, :conditions => {THREAD CONTAINS MESSAGES WHICH ARE UNREAD (have no 'read' models tying a user to a message)} I was thinking of either writing a long condition with multiple joins, or possibly writing giving the model an updated_threads method to return this, but I'd like to see if there is an easier way first. Any ideas? Also, if there is something fundamentally wrong with my structure for this functionality let me know! Thanks!!

• A simple WCF Service (POX) without complex serialization

  - by jammer59

  I'm a complete WCF novice. I'm trying to build a deploy a very, very simple IIS 7.0 hosted web service. For reasons outside of my control it must be WCF and not ASMX. It's a wrapper service for a pre-existing web application that simply does the following: 1) Receives a POST request with the request body XML-encapsulated form elements. Something like valuevalue. This is untyped XML and the XML is atomic (a form) and not a list of records/objects. 2) Add a couple of tags to the request XML and the invoke another HTTP-based service with a simple POST + bare XML -- this will actually be added by some internal SQL ops but that isn't the issue. 3) Receive the XML response from the 3rd party service and relay it as the response to the original calling client in Step 1. The clients (step 1) will be some sort of web-based scripting but could be anything .aspx, python, php, etc. I can't have SOAP and the usual WCF-based REST examples with their contracts and serialization have me confused. This seems like a very common and very simple problem conceptually. It would be easy to implement in code but IIS-hosted WCF is a requirement. Any pointers?

• Twitter OAuth, Error when trying to POST direct message.

  - by Darxval

  So I am building a java script that is used in conjunction of my C++ application for sending direct messages to users. the script does the work of building the request that i send. When i send a request i receive "Incorrect signature" or "can not authenticate you" Does anyone see something i am missing or am doing wrong? I am continuing to investigate. Thank you in advance Javascript: var nDate = new Date(); var epoch = nDate.getTime(); var nounce = ""; nounce = Base64.encode(epoch+randomString()); var Parameters = [ "oauth_consumerkey="+sConsumerKey, "oauth_nonce="+nounce, "oauth_signature_method=HMAC-SHA1", "oauth_timestamp="+epoch, "oauth_token="+sAccessToken, "oauth_version=1.0", "text="+sText, "user="+sUser]; var SortedParameters = Parameters.sort(); var joinParameters = SortedParameters.join("&"); var encodeParameters = escape(joinParameters); signature_base_string = escape("POST&"+NormalizedURL+"&"+encodeParameters); signature_key = sConsumerSecret+"&"+sAccessSecret; signature = Base64.encode(hmacsha1(signature_base_string,signature_key)); sAuthHeader = " OAuth realm=, oauth_nonce="+nounce+", oauth_timestamp="+epoch+", oauth_consumer_key="+sConsumerKey+", oauth_signature_method=HMAC-SHA1, oauth_version=1.0, oauth_signature="+signature+", oauth_token="+sAccessToken+", text="+sText; goNVOut.Set("Header.Authorization: ", sAuthHeader);

• Does overloading Grails static 'mapping' property to bolt on database objects violate DRY?

  - by mikesalera

  Does Grails static 'mapping' property in Domain classes violate DRY? Let's take a look at the canonical domain class: class Book {      Long id      String title      String isbn      Date published      Author author      static mapping = {             id generator:'hilo', params:[table:'hi_value',column:'next_value',max_lo:100]      } } or: class Book { ...         static mapping = {             id( generator:'sequence', params:[sequence_name: "book_seq"] )     } } And let us say, continuing this thought, that I have my Grails application working with HSQLDB or MySQL, but the IT department says I must use a commercial software package (written by a large corp in Redwood Shores, Calif.). Does this change make my web application nobbled in development and test environments? MySQL supports autoincrement on a primary key column but does support sequence objects, for example. Is there a cleaner way to implement this sort of 'only when in production mode' without loading up the domain class?

• Check mail attachment

  - by comii

  Hi! I am using vb.net to display email from outlook express! Everything work fine but when some message has attachment, i can not display message that email has attachment!

• Help with php code - need to add condition to make one link https

  - by Kaskade

  Hi, I have a wordpress blog and I need to make one of the pages secure. I have been told to make the link to that page point to https://claimpage.html as opposed to http://claimpage.html. The problem is I don't actually create the menu that links the user to the individual pages. This is done automatically by the code in the background. I think I need to put in some sort of an IF statement, saying, if the title of the page is "claim now" then use https otherwise use http. I found this code in the header.php so I think my changes need to go in here but I'm not really sure what to do. <div id="navbar"> <ul class="menu"> <li class="<?php if ( is_home() ) { ?>current_page_item<?php } else { ?>page_item<?php } ?>"><a href="<?php echo get_settings('home'); ?>"><?php _e('Home'); ?></a></li> <?php wp_list_pages('sort_column=id&depth=1&title_li='); ?> <?php wp_register('<li>','</li>'); ?> </ul> </div> <!-- end of #navbar --> Any suggestions as to how I can make one page that I know the title and url or https while the others are kept using normal http? The site is hosted on a secure server so I do have an ssl certificate.

• Self-referencing tables in Linq2Sql

  - by J-Man

  Hi, I've seen a lot of questions on self-referencing tables in Linq2Sql and how to eagerly load all child records for a particular root object. I've implemented a temporary solution by accessing all underlying properties, but you can see that this doesn't do the performance any good. The thing is though, that all records are correlated with each-other using a correlation GUID. Example below: RootElement - Id: 1 - ParentId: null - CorrelationId: 4D68E512-4B55-44f4-BA5A-174B630A03DD ChildElement1 - Id: 2 - ParentId: 1 - CorrelationId: 4D68E512-4B55-44f4-BA5A-174B630A03DD ChildElement2 - Id: 3 - ParentId: 2 - CorrelationId: 4D68E512-4B55-44f4-BA5A-174B630A03DD ChildElement1 - Id: 4 - ParentId: 2 - CorrelationId: 4D68E512-4B55-44f4-BA5A-174B630A03DD In my case, I do have access to the correlationId, so I can retrieve all of my records by performing the following query: from element in db.Elements where element.CorrelationId == '4D68E512-4B55-44f4-BA5A-174B630A03DD' select element; But, of course, I want these elements associated with each other by executing this query: from element in db.Elements where element.CorrelationId == '4D68E512-4B55-44f4-BA5A-174B630A03DD' && element.ParentId == null select element; My question is: is it possible to combine the results the first query as some sort of 'caching mechanism' for the query where I get the root element? Thanks for the input. J.

• Printing Arrays from Structs

  - by Carlll

  I've been stumped for a few hours on an exercise where I must use functions to build up an array inside a struct and print it. In my current program, it compiles but crashes upon running. #define LIM 10 typedef char letters[LIM]; typedef struct { int counter; letters words[LIM]; } foo; int main(int argc, char **argv){ foo apara; structtest(apara, LIM); print_struct(apara); } int structtest(foo *p, int limit){ p->counter = 0; int i =0; for(i; i< limit ;i++){ strcpy(p->words[p->counter], "x"); //only filling arrays with 'x' as an example p->counter ++; } return; I do believe it's due to my incorrect usage/combination of pointers. I've tried adjusting them, but either an 'incompatible types' error is produced, or the array is seemingly blank } void print_struct(foo p){ printf(p.words); } I haven't made it successfully up to the print_struct stage, but I'm unsure whether p.words is the correct item to be calling. In the output, I would expect the function to return an array of x's. I apologize in advance if I've made some sort of grievous "I should already know this" C mistake. Thanks for your help.

• Why does the Combo.SelectedValue get lost after some time

  - by tzup

  So I have this asp:DropDownList on a page. It renders like this (in IE7): <select name="ctl00$cphFilter$cbLista" onchange="javascript:setTimeout('__doPostBack(\'ctl00$cphFilter$cbLista\',\'\')', 0)" id="ctl00_cphFilter_cbLista" class="agsSelect"> <option selected="selected" value="4350">A</option> <option value="4352">B</option> <option value="4349">C</option> <option value="4348">D</option> And then I have a grid and a button on the same page. When the user clicks the button the selected item of the dropdown is read (well a datasource object reads it) and the grid does a databind after a trip to a DB where it gets some data based on that selected value. This works fine most of the time. However sometimes, the selection in the dropdownlist seems to get lost even though the rendered page says the A is the selected item. The datasource object is defined like this: <asp:ObjectDataSource ID="dsVM" runat="server" EnablePaging="False" SelectMethod="Select" SortParameterName="sort" TypeName="X.Business.Entities.LPVM.BE"> <SelectParameters> <asp:ControlParameter Name="listaId" Type="Int32" ControlID="cphFilter$cbLista" PropertyName="SelectedValue" /> </SelectParameters> </asp:ObjectDataSource> Any ideas why the grid would reload its data with a select parameter that is 0 instead of the selected value of the dropdownlist? EDIT Suppose the dropdownlist is bound, the user selected B and the grid is bound as well and shows the right data. Now, I wait 2 minutes and I click the Refresh button. Surprisingly, at this particular moment the dropdownlist.SelectedValue (which I already know it was 4352 before I clicked because that's how it looks in the rendered page) is actually an empty string. Where did the value go?

• Categories of tags

  - by Peter Rowell

  I'm starting a pro bono project that is the web interface to the world's largest collection of lute music and it's a challenging collection from several points of view. The pieces are largely from 1400 to 1600, but they range from the mid-1200's to present day. Needless to say, there is tremendous variability in how the pieces are categorized and who they are attributed to. It is obvious that any sort of rigid, DB-enforced hierarchy isn't going to work with this collection, so my thoughts turn to tags. But not all tags are the same. I'll have tags that represent a person/role (composer, translator, entabulator, etc.), tags that represent the instrument(s) the piece in written for, and tags that represent how the piece has been classified by any one of half a dozen different classification systems used over the centuries. We will be using a semi-controlled tag vocabulary to prevent runaway tag proliferation (e.g. del.icio.us), but I want to treat the tags as belonging to different groups. People tags should not be offered when the editor is doing instrument tagging, etc. Has anyone done something like this? I have several ways I can think of to do it, but if there is an existing system that is well-done it would save me time implementing/debugging. FWIW: This is a Django system and I'm looking at starting with Django-tagging and then hacking from there, possibly adding a category field or ...

• Daily, Weekly and Monthly Page View Counter

  - by Jens Fahnenbruck

  I'm building a website with user generated content. On the home page I want to show a list of all created items, and I want to be able to sort them by a view counter. That's sound easy, but I want multiple counters. I want to know which was the most visited item in the last day, last week or last months or overall. My first Idea was to create 4 counter columns in the item's DB-Table. One for each of daily, weekly, monthly and overall, and the create a cron job, that clears the daily counter every 24 hours, the weekly counter every 7 days and so on. But my problem with this is, what happens if I want to know which was the most viewed item of the week, just after the weekly counter got cleared? What I need is an efficient way to create a continous counter, which got reduced for every page view that is too old, and increased for every new page view. Right now I'm thinking of a solution with the redis server, but I have no solution yet. I'm just looking for a general idea here, but FYI I'm developing this application in Ruby on Rails.

• Parsing RSS2 In PHP

  - by mrduclaw

  I'm trying to get content from an RSS2 feed from one of my sites and use it in another site. The feed is here. And the code I'm using is taken from this nice site and has been modified like the following: $doc = new DOMDocument(); $doc->load('http://tripleax.com/john/?feed=rss2'); $arrFeeds = array(); foreach ($doc->getElementsByTagName('item') as $node) { print('<div style="width:100%" class="option"><strong>'); $a = $node->getElementsByTagName('title')->item(0)->nodeValue; print("$a"); print('</strong><br /><span class="option">'); $a = $node->getElementsByTagName('description')->item(0)->nodeValue; print("$a");` } The problem I'm having is, I want to display the entire post's contents. And the description is a sort of the teaser. Changing $node->getElementsByTagName('description')->item(0)->nodeValue to $node->getElementsByTagName('content')->item(0)->nodeValue gives me nothing, and content:encoded is no better. Can someone please point me in the right direction to solving this? Thanks!

• Flex: embedded fonts not being applied correctly in Label and DataGrid

  - by lje

  Folks, I am observing a problem with how an embedded font is applied to certain Flex components, namely mx:Label and mx:DataGrid. I have a CSS that declares three variations on an embedded font as follows: @font-face { src:url("buttons.swf"); font-family: "Arial"; } @font-face { src:url("buttons.swf"); font-family: "Arial"; font-weight: bold; } @font-face { src:url("buttons.swf"); font-family: "Arial"; font-style: italic; } And in the style declaration for Label and DataGrid, I have: Label { fontFamily: "Arial"; fontSize: 11; fontFamily: LucidaSans; } and DataGrid { fontFamily: "Arial"; height: 16; } (I've snipped some stuff from both style rules, so if you think there's something that may be causing a conflict I can certainly post the entire definition. It's mostly color, line and padding stuff for the DataGrid.) The problem that is for both Label and cells in the DataGrid the text is being rendered as sort of a times new roman font. The headers in the DataGrid are fine, just the text in the cells is wonky. All other components use the correct font as defined in the CSS/SWF. Any ideas why this is happening?

• CakePHP form $options['options']

  - by James

  Hey! Total CakePHP noob here. This is sort of a two fold question. In a view that is used for adding user objects I would like to use a drop down (selection) field in the form. Each user belongs to a group so when I add a user I want a drop down that contains all of the groups that the user could possibly join. Currently the group_id field is a textfield. I know how to force it to be a selection field, but I don't know how to populate the selection with the names of the groups programmatically. The Current method: echo $form->input('group_id', array( '1' => 'NameOfGroup1', '2' => 'NameOfGroup2', '3' => 'NameOfGroup3') ); I want to generate the options array programmatically though. echo $form->input('group_id', $this->Group->find('list')); This doesn't work though. I get an error: Undefined property: View::$Group [APP/views/users/add.ctp, line 8] To me this means that I don't have access to the Group object from inside my user view. How can I accomplish this? Again, I want to do it programmatically so that it updates as I add groups or remove them.

• Type-conditional controls in Haskell

  - by estanford

  I'm going through the 99 Haskell problems to build my proficiency with the language. On problem 7 ("Flatten a nested list structure"), I found myself wanting to define a conditional behavior based on the type of argument passed to a function. That is, since *Main> :t 1 1 :: (Num t) => t *Main> :t [1,2] [1,2] :: (Num t) => [t] *Main> :t [[1],[2]] [[1],[2]] :: (Num t) => [[t]] (i.e. lists nested at different levels have different data types) it seems like I should be able to write a function that can read the type of the argument, and then behave accordingly. My first attempt was along these lines: listflatten l = do if (:t l) /= ((Num t) => [t]) then listflatten (foldl (++) [] l) else id l But when I try to do that, Haskell returns a parse error. Is Haskell flexible enough to allow this sort of type manipulation, do I need to find another way?

• Serializing MDI Winforms for persistency

  - by Serge

  Hello, basically my project is an MDI Winform application where a user can customize the interface by adding various controls and changing the layout. I would like to be able to save the state of the application for each user. I have done quite a bit of searching and found these: http://stackoverflow.com/questions/2076259/how-to-auto-save-and-auto-load-all-properties-in-winforms-c http://stackoverflow.com/questions/1669522/c-save-winform-or-controls-to-file Basically from what I understand, the best approach is to serialize the data to XML, however winform controls are not serializable, so I would have use surrogate classes: http://www.codeproject.com/KB/dotnet/Surrogate_Serialization.aspx Now, do I need to write a surrogate class for each of my controls? I would need to write some sort of a recursive algorithm to save all my controls, what is the best approach to do accomplish that? How would I then restore all the windows, should I use the memento design pattern for that? If I want to implement multiple users later, should I use Nhibernate to store all the object data in a database? I am still trying to wrap my head around the problem and if anyone has any experience or advice I would greatly appreciate it, thanks.

• when updating location.hash in Chrome the jQuery animation "freezes" for a second

  - by ubunut

  I'm trying to create a sort of "virtual gallery". I'm using Coda Slider 2.0 & jQuery v1.4.2 It behaves perfectly in IE, FF & Safari, but Chrome seems to reload/hang for a second when setting location.hash. This causes the jQuery animation to freeze for a second :S Example: http://hardyernst.dk/gallery.html try clicking on the navigation links above the pictures. The jQuery code that is being executed when clicking a navigation link: $('#coda-nav-' + sliderCount + ' a').each(function(z) { // What happens when a nav link is clicked $(this).bind("click", function() { offset = -(panelWidth*z); navClicks++; $(this).addClass('current').parents('ul').find('a').not($(this)).removeClass('current'); alterPanelHeight(z); currentPanel = z + 1; $('.panel-container', slider).stop().animate({ left: offset }, settings.slideEaseDuration, settings.slideEaseFunction, function(){ if (!settings.crossLinking) { return false; } // Don't change the URL hash unless cross-linking is specified }); }); }); if I add return false; at the end of the function. The animation will slide smoothly :)... BUT as you might have guessed the location.hash value remains unchanged :( I have tried setting the location.hash earlier in the function alas it did not change the behavior in Chrome Would be immensely grateful for any help :) Regards Ubunut

• Forcing file redirection on x64 for a 32-bit application

  - by Paul Alexander

  The silent redirection of 64-bit system files to their 32-bit equivalents can be turned off and reverted with Wow64DisableWow64FsRedirection and Wow64RevertWow64FsRedirection. We use this for certain file identity checks in our application. The problem is that in performing some of theses tasks, we might call a framework or Windows API in a DLL that has not yet been loaded. If redirection is enabled at that time, the wrong version of the dll may be loaded resulting in a XXX is not a valid Win32 application error. I've identified the few API calls in question and what I'd like to do force the redirection on for the duration of that call then revert it back - just the opposite of the provided Win32 APIs. Unfortunately these calls do not provide any sort of WOW64 compatibility flag like some of the registry methods do. The obvious alternative is to use Wow64EnableWow64FsRedirection, pass TRUE for Wow64FsEanbledRedirection. However there are a variety of warnings about the use of this method and a note that it is not compatible with Disable/Revert combo methods that have replaced it. Is there a safe way to force redirection on for a give Win32 call? The docs state the redirection is thread specific so I've considered spinning up a new thread for the specific call with appropriate locks and waits, but I was hoping for a simpler solution.

• Is there a disassembler + debugger for java (ala OllyDbg / SoftICE for assembler)?

  - by Ran Biron

  Is there a utility similar to OllyDbg / SoftICE for java? I.e. execute class (from jar / with class path) and, without source code, show the disassembly of the intermediate code with ability to step through / step over / search for references / edit specific intermediate code in memory / apply edit to file... If not, is it even possible to write something like this (assuming we're willing to live without hotspot for the debug duration)? Edit: I'm not talking about JAD or JD or Cavaj. These are fine decompilers, but I don't want a decompiler for several reasons, most notable is that their output is incorrect (at best, sometimes just plain wrong). I'm not looking for a magical "compiled bytes to java code" - I want to see the actual bytes that are about to be executed. Also, I'd like the ability to change those bytes (just like in an assembly debugger) and, hopefully, write the changed part back to the class file. Edit2: I know javap exists - but it does only one way (and without any sort of analysis). Example (code taken from the vmspec documentation): From java code, we use "javac" to compile this: void setIt(int value) { i = value; } int getIt() { return i; } to a java .class file. Using javap -c I can get this output: Method void setIt(int) 0 aload_0 1 iload_1 2 putfield #4 5 return Method int getIt() 0 aload_0 1 getfield #4 4 ireturn This is OK for the disassembly part (not really good without analysis - "field #4 is Example.i"), but I can't find the two other "tools": A debugger that goes over the instructions themselves (with stack, memory dumps, etc), allowing me to examine the actual code and environment. A way to reverse the process - edit the disassembled code and recreate the .class file (with the edited code).

• Outlook 2010 Retrieving and restricting appointments programmatically causing recurrences to be incl

  - by Mike Dearing

  I wrote a winforms app that uses Microsoft.Office.Interop.Outlook to retrieve and restrict appointments based upon the date range entered by a user. This worked fine with Outlook 2007 installed, however now that some users have updated to Outlook 2010 the appointment retrieval is pulling back incorrect appointments along with the correct ones falling within the specified date range. The additional incorrect appointments being retrieved always appear to be recurring appointments. I was wondering if this is a known bug and if so what exactly is happening that is causing these additional recurring appointments to come in? I'd rather not have to throw in a workaround where I step through the items after they have been restricted and remove the extra ones, when this functionality works fine with 2007. Note: I've not recompiled or updated any code when experiencing this issue, just running the old program. This is the spot in my code where appointments are being restricted. This is similar to the way advised in the following msdn link: http://msdn.microsoft.com/en-us/library/bb611267.aspx Microsoft.Office.Interop.Outlook.Items outlookItems = outlookMapiFolder.Items.Restrict( "[Start] >= '" + outlookImport.startDay.ToString("g") + "' AND [Start] <= '" + outlookImport.endDay.ToString("g") + "'"); outlookItems.Sort("[Start]", Type.Missing); outlookItems.IncludeRecurrences = true;
