Group method parameter or individual parameter?

- by Nassign

I would like to ask on method parameters design consideration. I am usually deciding between using individual variables as parameters versus grouping them to a class or dictionary as one parameter. Is there such a rule when you should use individual parameter against using a class or a dictionary to group the parameter? Individual parameter - Straight forward, strongly typed Dictionary parameter - Very extensible, like HTTP request but cannot be strongly typed. Class parameter - Extensible by adding member to the class parameter, strongly typed. I am looking for a design reference on when to use which? Note: I am not sure if this question is valid in programmers but I definitely think it would be closed in stackoverflow, If it is still not valid, please point me to the proper page.

How to measure the conversion rate of your Amazon affiliate program?

- by user359650

I plan on selling products through the Amazon affiliate program. What I know I can track is: -what products people view on my website (default Google Analytics pageview behaviour). -what affiliate links people click on my website (with GA _trackEvent). What am I missing is: -what products people end up buying after clicking on the affiliate links. Does the Amazon affiliate program offers you any mechanism for linking a purchase with some data from your website? I noticed that I was able to add custom parameters and values to my affiliate links and the link checker was still happy with them, if Amazon gave the links that initiated an order then I would be able to cross reference the orders using custom parameters...

Plan variable and call dependencies

- by Gerenuk

I'd like to write down the design of my program to understand the dependencies and calls better. I know there are class diagrams which show inheritance and attribute variables. However I'd also like to document the input parameters to method functions and in particular which calls the methods function executes inside (e.g. on the input parameters). Also sometimes it might be useful to show how actual objects are connected (if there is a standard structure). This way I can have a better understanding of the modules and design before starting to program. Can you suggest a method to do this software design? It should be one-to-one to programming code structure so that I really notice all quirks beforehand (instead of high-level design where thing are hard to implement without further work). Maybe some special diagram or tool or a combination? It is static dependency and call design rather than time dependent execution monitoring. (I use Python if you have any specialized recommendations).

OpenGL ES, orthopgraphics projection and viewport

- by DarkDeny

I want to make some simple 2D game on iOS to familiarize myself with OpenGL ES. I started with Ray Wenderlich tutorial (How To Create A Simple 2D iPhone Game with OpenGL ES 2.0 and GLKit). That tutorial is quite good, but I miss some parts of a puzzle. Ray creates orthographic projection using some magic numbers like 480 and 320. It is not clear to me why did he take these numbers, and as far as I can see - sprite is not mapped to the ipad simulator screen one-to-one pixel. I tried to play with parameters with which ortho matrix is created, but I cannot figure out what math is here. How can I calculate numbers (bottom, top, left, right, close, far) which will be parameters to orthographic projection matrix creation and have sprite on the screen shown in its original size?

GA tracking utm query params after hashbang

- by hybrid9

We currently use a hashbang for the portion of our site that generates dynamic content which can also be deep linked. Our analytics team wants to use utm params to track the referral traffic from social networks. We are using Universal Analytics (analytics.js) as well as GTM. Will GA pick up the query parameters after the hashbang or does it always have to go before? For example: example.com/#!/some/content?utm_source=foo&utm_campaign=bar example.com?utm_source=foo&utm_campaign=bar/#!/some/content In #1, I'm concerned that the utm params won't be recorded and in #2 the page will break or the url could be incorrectly written. How does GA pull in those parameters - location.search? regex? Can I get away with using either?

Documenting sp_ssiscatalog

- by jamiet

What is the best way to document an API? Moreover, what is the best way to document a T-SQL API? Before I try to answer those questions I should explain what I mean by “a T-SQL API”. I think of an API as being a collection of well-defined, known, code modules that provide some notion of a service to whomever uses it; in T-SQL terms I tend to think of a collection of stored procedures and functions as a form of API. Its a loose definition, I admit, and in SQL Server circles we don’t tend to think of stored procedures collectively as an API but if you think about it that’s exactly what they are. The question of how to document a T-SQL API came to my mind as I worked on sp_ssiscatalog. How could I make it easy for people to learn about the capabilities of sp_ssiscatalog without forcing them to dig through the code and find out for themselves? My opening gambit was to write documentation pages on the wiki at http://ssisreportingpack.codeplex.com. That’s kinda useful but it does suffer the disadvantage that someone using sp_ssiscatalog needs to go visit a webpage to read it – I want the documentation to be available wherever the user is using sp_ssiscatalog. Moreover, maintaining the wiki is a real PITA. Intellisense works up to a point, I guess: but that only shows whatever SQL Server knows about the various parameters, which isn’t all that much! I wanted a better way for my API users to learn about its capabilities and so I hit upon the idea of simply using PRINT statements within the code itself to inform the user what options are available; hence I added such PRINT statements in the latest check-in. Now when you execute (for example): EXEC sp_ssiscatalog @operation_type='execs' you can hit F6 a few times to view the messages pane and you shall see something like this: Notice that I’m returning information about all the parameters that can be used to affect the results that just got returned. I really do think this will be very useful to anyone using sp_ssiscatalog; I myself am always forgetting what the parameters are and I wrote the damn thing so I can’t really expect anyone else to remember them. I have not yet made available a release that has these changes in it but when I do I’ll blog about it right here. At the time of writing the latest available release of sp_ssiscatalog is DB v1.0.1.0 but if you want to the latest and greatest simply download it straight from source. Feedback is welcome as always. @Jamiet

After 14.04 update video/totem won't play midi

- by bruce

Prior to the upgrade, I could be on wikipedia and play the 'play' links fine where totem would open a window and have screen graphics go on. Now, after researching, installing VLC and it's extensions, making sure the gnome codec installer is activated, and on and on, all I get is : "The parameters passed to the application had an invalid format. Please file a bug! The parameters were: --transient-for=16777296 gstreamer|1.0|totem-plugin-viewer|audio/x-midi-event decoder|decoder-audio/x-midi-event" When totem/video opens and I'm not sure whether the bug is being reported or not. Meaning I don't know if APPOrt is active for this as there's no box with a checkmark in it display. AND the window for totem/video ALWAYS has the sound muted when it opens.

Interaction of a GUI-based App and Windows Service

- by psubsee2003

I am working on personal project that will be designed to help manage my media library, specifically recordings created by Windows Media Center. So I am going to have the following parts to this application: A Windows Service that monitors the recording folder. Once a new recording is completed that meets specific criteria, it will call several 3rd party CLI Applications to remove the commercials and re-encode the video into a more hard-drive friendly format. A controller GUI to be able to modify settings of the service, specifically add new shows to watch for, and to modify parameters for the CLI Applications A standalone (GUI-based) desktop application that can perform many of the same functions as the windows service, expect manually on specific files instead of automatically based on specific criteria. (It should be mentioned that I have limited experience with an application of this complexity, and I have absolutely zero experience with Windows Services) Since the 1st and 3rd bullet share similar functionality, my design plan is to pull the common functionality into a separate library shared by both parts applications, but these 2 components do not need to interact otherwise. The 2nd and 3rd bullets seem to share some common functionality, both will have a GUI, both will have to help define similar parameters (one to send to the service and the other to send directly to the CLI applications), so I can see some advantage to combining them into the same application. On the other hand, the standalone application (bullet #3) really does not need to interact with the service at all, except for possibly sharing a few common default parameters that can easily be put into an XML in a common location, so it seems to make more sense to just keep everything separate. The controller GUI (2nd bullet) is where I am stuck at the moment. Do I just roll this functionality (allow for user interaction with the service to update settings and criteria) into the standalone application? Or would it be a better design decision to keep them separate? Specifically, I'm worried about adding the complexity of communicating with the Windows Service to the standalone application when it doesn't need it. Is WCF the right approach to allow the controller GUI to interact with the Windows Service? Or is there a better alternative? At the moment, I don't envision a need for a significant amount of interaction, maybe just adding a new task once in a while and occasionally tweaking a parameter, but when something is changed, I do expect the windows service to immediately use the new settings.

How to generate SPMetal for a specific list (OOTB: like tasks or contacts) with custom columns

- by KunaalKapoor

SPMetal is used to make use of LINQ on a list in SharePoint 2010. By default when you generate SPMetal on a site you will get a code generated file for most of the lists and probably more. Here is a MSDN link for some info on SPMetal.http://msdn.microsoft.com/en-us/library/ee538255(office.14).aspxBut what if you want only to generate the code for one list?Well it is quite simple once you figure it out. You need to add an xml file to override the default settings of SPMetal and specify it in the /parameters option. I will show you how to do this.First create a Folder that will contain two files (GenerateSPMetalCode.bat and SPMetal.xml).Below is the content of the files:GenerateSPMetalCode.bat "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN\SPMetal" /web:http://YourServer /code:OutPutFileName.cs /language:csharp /parameters:SPMetal.xml pause SPMetal.xml <?xml version="1.0" encoding="utf-8"?> <Web AccessModifier="Internal" xmlns="http://schemas.microsoft.com/SharePoint/2009/spmetal"> <List Name="ListName"> <ContentType Name="ContentTypeName" Class="GeneratedClassName" /> </List> <ExcludeOtherLists></ExcludeOtherLists> </Web> You will have to change some of the text in the files so that it will be specific to your SharePoint Server Setup. In the bat file you will have to change http://YourServer to the url of the web where your list is. In the SPMetal.xml file you need to change ListName to the name of your list and the ContentTypeName to the name of the content type you want to extract. The GeneratedClassName can be anything but perhaps you should rename it to something more sensible.Adding the following line: '<List Name="ListName"><ContentType Name="ContentTypeName" Class="GeneratedClassName" /> </List>' makes sure that any custom columns added to an OOTB list like contacts or tasks are also generated, which are missed out in a regular generation.So now when you run it the SPMetal command will read the SPMetal.xml list and override its commands. ExcludeOtherLists element makes it so that only the code for the lists you specify will be generated. For some reason I got an error if I had this element above the List element.You sould now have a code file called OutPutFileName.cs that has been generated. You can now put this in your SharePoint project for use with your LINQ queries against that list.I will soon write a LINQ example that uses the generated class. UPDATE: Add the /namespace parameter to add a namespace to the generated code. "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN\SPMetal" /web:http://YourServer /namespace:MySPMetalNameSpace /code:OutPutFileName.cs /language:csharp /parameters:SPMetal.xml

Is software support an option for your career?

- by Maria Sandu

Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 If you have a technical background, why should you choose a career in support? We have invited Serban to answer these questions and to give us an overview of one of the biggest technical teams in Oracle Romania. He’s been with Oracle for 7 years leading the local PeopleSoft Financials & Supply Chain Support team. Back in 2013 Serban started building a new support team in Romania – Fusion HCM. His current focus is building a strong support team for Fusion HCM, latest solution for Business HR Professionals from Oracle. The solution is offered both on Premise (customer site installation) but more important as a Cloud offering – SaaS. So, why should a technical person choose Software Support over other technical areas? “I think it is mainly because of the high level of technical skills required to provide the best technical solutions to our customers. Oracle Software Support covers complex solutions going from Database or Middleware to a vast area of business applications (basically covering any needs that a large enterprise may have). Working with such software requires very strong skills both technical and functional for the different areas, going from Finance, Supply Chain Management, Manufacturing, Sales to other very specific business processes. Our customers are large enterprises that already have a support layer inside their organization and therefore the Oracle Technical Support Engineers are working with highly specialized staff (DBA’s, System/Application Admins, Implementation Consultants). This is a very important aspect for our engineers because they need to be highly skilled to match our customer’s specialist’s expectations”. What’s the career path in your team? “Technical Analysts joining our teams have a clear growth path. The main focus is to become a master of the product they will support. I think one need 1 or 2 years to reach a good level of understanding the product and delivering optimal solutions because of the complexity of our products. At a later stage, engineers can choose their professional development areas based on the business needs and preferences and then further grow towards as technical expert or a management role. We have analysts that have more than 15 years of technical expertise and they still learn and grow in technical area. Important fact is, due to the expansion of the Romanian Software support center, there are various management opportunities. So, if you want to leverage your experience and if you want to have people management responsibilities Oracle Software Support is the place to be!” Our last question to Serban was about the benefits of being part of Oracle Software Support. Here is what he said: “We believe that Oracle delivers “State of the art” Support level to our customers. This is not possible without high investment in our staff. We commit from the start to support any technical analyst that joins us (being junior or very senior) with any training needs they have for their job. We have various technical trainings as well as soft-skills trainings required for a customer facing professional to be successful in his role. Last but not least, we’re aiming to make Oracle Romania SW Support a global center of excellence which means we’re investing a lot in our employees.” If you’re looking for a job where you can combine your strong technical skills with customer interaction Oracle Software Support is the place to be!

How can I estimate the entropy of a password?

- by Wug

Having read various resources about password strength I'm trying to create an algorithm that will provide a rough estimation of how much entropy a password has. I'm trying to create an algorithm that's as comprehensive as possible. At this point I only have pseudocode, but the algorithm covers the following: password length repeated characters patterns (logical) different character spaces (LC, UC, Numeric, Special, Extended) dictionary attacks It does NOT cover the following, and SHOULD cover it WELL (though not perfectly): ordering (passwords can be strictly ordered by output of this algorithm) patterns (spatial) Can anyone provide some insight on what this algorithm might be weak to? Specifically, can anyone think of situations where feeding a password to the algorithm would OVERESTIMATE its strength? Underestimations are less of an issue. The algorithm: // the password to test password = ? length = length(password) // unique character counts from password (duplicates discarded) uqlca = number of unique lowercase alphabetic characters in password uquca = number of uppercase alphabetic characters uqd = number of unique digits uqsp = number of unique special characters (anything with a key on the keyboard) uqxc = number of unique special special characters (alt codes, extended-ascii stuff) // algorithm parameters, total sizes of alphabet spaces Nlca = total possible number of lowercase letters (26) Nuca = total uppercase letters (26) Nd = total digits (10) Nsp = total special characters (32 or something) Nxc = total extended ascii characters that dont fit into other categorys (idk, 50?) // algorithm parameters, pw strength growth rates as percentages (per character) flca = entropy growth factor for lowercase letters (.25 is probably a good value) fuca = EGF for uppercase letters (.4 is probably good) fd = EGF for digits (.4 is probably good) fsp = EGF for special chars (.5 is probably good) fxc = EGF for extended ascii chars (.75 is probably good) // repetition factors. few unique letters == low factor, many unique == high rflca = (1 - (1 - flca) ^ uqlca) rfuca = (1 - (1 - fuca) ^ uquca) rfd = (1 - (1 - fd ) ^ uqd ) rfsp = (1 - (1 - fsp ) ^ uqsp ) rfxc = (1 - (1 - fxc ) ^ uqxc ) // digit strengths strength = ( rflca * Nlca + rfuca * Nuca + rfd * Nd + rfsp * Nsp + rfxc * Nxc ) ^ length entropybits = log_base_2(strength) A few inputs and their desired and actual entropy_bits outputs: INPUT DESIRED ACTUAL aaa very pathetic 8.1 aaaaaaaaa pathetic 24.7 abcdefghi weak 31.2 H0ley$Mol3y_ strong 72.2 s^fU¬5ü;y34G< wtf 88.9 [a^36]* pathetic 97.2 [a^20]A[a^15]* strong 146.8 xkcd1** medium 79.3 xkcd2** wtf 160.5 * these 2 passwords use shortened notation, where [a^N] expands to N a's. ** xkcd1 = "Tr0ub4dor&3", xkcd2 = "correct horse battery staple" The algorithm does realize (correctly) that increasing the alphabet size (even by one digit) vastly strengthens long passwords, as shown by the difference in entropy_bits for the 6th and 7th passwords, which both consist of 36 a's, but the second's 21st a is capitalized. However, they do not account for the fact that having a password of 36 a's is not a good idea, it's easily broken with a weak password cracker (and anyone who watches you type it will see it) and the algorithm doesn't reflect that. It does, however, reflect the fact that xkcd1 is a weak password compared to xkcd2, despite having greater complexity density (is this even a thing?). How can I improve this algorithm? Addendum 1 Dictionary attacks and pattern based attacks seem to be the big thing, so I'll take a stab at addressing those. I could perform a comprehensive search through the password for words from a word list and replace words with tokens unique to the words they represent. Word-tokens would then be treated as characters and have their own weight system, and would add their own weights to the password. I'd need a few new algorithm parameters (I'll call them lw, Nw ~= 2^11, fw ~= .5, and rfw) and I'd factor the weight into the password as I would any of the other weights. This word search could be specially modified to match both lowercase and uppercase letters as well as common character substitutions, like that of E with 3. If I didn't add extra weight to such matched words, the algorithm would underestimate their strength by a bit or two per word, which is OK. Otherwise, a general rule would be, for each non-perfect character match, give the word a bonus bit. I could then perform simple pattern checks, such as searches for runs of repeated characters and derivative tests (take the difference between each character), which would identify patterns such as 'aaaaa' and '12345', and replace each detected pattern with a pattern token, unique to the pattern and length. The algorithmic parameters (specifically, entropy per pattern) could be generated on the fly based on the pattern. At this point, I'd take the length of the password. Each word token and pattern token would count as one character; each token would replace the characters they symbolically represented. I made up some sort of pattern notation, but it includes the pattern length l, the pattern order o, and the base element b. This information could be used to compute some arbitrary weight for each pattern. I'd do something better in actual code. Modified Example: Password: 1234kitty$$$$$herpderp Tokenized: 1 2 3 4 k i t t y $ $ $ $ $ h e r p d e r p Words Filtered: 1 2 3 4 @W5783 $ $ $ $ $ @W9001 @W9002 Patterns Filtered: @P[l=4,o=1,b='1'] @W5783 @P[l=5,o=0,b='$'] @W9001 @W9002 Breakdown: 3 small, unique words and 2 patterns Entropy: about 45 bits, as per modified algorithm Password: correcthorsebatterystaple Tokenized: c o r r e c t h o r s e b a t t e r y s t a p l e Words Filtered: @W6783 @W7923 @W1535 @W2285 Breakdown: 4 small, unique words and no patterns Entropy: 43 bits, as per modified algorithm The exact semantics of how entropy is calculated from patterns is up for discussion. I was thinking something like: entropy(b) * l * (o + 1) // o will be either zero or one The modified algorithm would find flaws with and reduce the strength of each password in the original table, with the exception of s^fU¬5ü;y34G<, which contains no words or patterns.

Design pattern: static function call with input/output containers?

- by Pavlo Dyban

I work for a company in software research department. We use algorithms from our real software and wrap them so that we can use them for prototyping. Every time an algorithm interface changes, we need to adapt our wrappers respectively. Recently all algorithms have been refactored in such a manner that instead of accepting many different inputs and returning outputs via referenced parameters, they now accept one input data container and one output data container (the latter is passed by reference). Algorithm interface is limited to a static function call like that: class MyAlgorithm{ static bool calculate(MyAlgorithmInput input, MyAlgorithmOutput &output); } This is actually a very powerful design, though I have never seen it in a C++ programming environment before. Changes in the number of parameters and their data types are now encapsulated and they don't change the algorithm callback. In the latest algorithm which I have developed I used the same scheme. Now I want to know if this is a popular design pattern and what it is called.

How should UI layer pass user input to BL layer?

- by BornToCode

I'm building an n-tier application, I have UI, BL, DAL & Entities (built from POCO) projects. (All projects have a reference to the Entities). My question is - how should I pass user input from the UI to the BL, as a bunch of strings passed to the BL method and the BL will build the object from the parameters, or should I build the objects inside the UI submit_function and send objects as parameters? EDIT: I wrote n-tier application, but what I actually meant was just layers.

How can I read the verbose output from a Cmdlet in C# using Exchange Powershell

- by mrkeith

Environment: Exchange 2007 sp3 (2003 sp2 mixed mode) Visual Studio 2008, .Net 3.5 Hello, I'm working with an Exchange powershell move-mailbox cmdlet and have noted when I do so from the Exchange Management shell (using the Verbose switch) there is a ton of real-time information provided. To provide a little context, I'm attempting to create a UI application that moves mailboxes similarly to the Exchange Management Console but desire to support an input file and specific server/database destinations for each entry (and threading). Here's roughly what I have at present but I'm not sure if there is an event I need to register for or what... And to be clear, I desire to get this information in real-time so I may update my UI to reflect what's occurring in the move sequence for the appropriate user (pretty much like the native functionality offered in the Management Console). And in case you are wondering, the reason why I'm not content with the Management Console functionality is, I have an algorithm which I'm using to balance users depending on storage limit, Blackberry use, journaling, exception mailbox size etc which demands user be mapped to specific locations... and I do not desire to create many/several move groups for each common destination or to hunt for lists of users individually through the management console UI. I can not seem to find any good documentation or examples of how to tie into reading the verbose messages that are provided within the console using C# (I see value in being able to read this kind of information in many different scenarios). I've explored the Invoke and InvokeAsync methods and the StateChanged & DataReady events but none of these seem to provide the information (verbose comments) that I'm after. Any direction or examples that can be provided will be very appreciated! A code sample which is little more than how I would ordinarily call any other powershell command follows: // config to use ExMgmt shell, create runspace and open it RunspaceConfiguration rsConfig = RunspaceConfiguration.Create(); PSSnapInException snapInException = null; PSSnapInInfo info = rsConfig.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.Admin", out snapInException); if (snapInException != null) throw snapInException; Runspace runspace = RunspaceFactory.CreateRunspace(rsConfig); try { runspace.Open(); // create a pipeline and feed script text Pipeline pipeline = runspace.CreatePipeline(); string targetDatabase = @"myServer\myStorageGroup\myDB"; string mbxOwner = "[email protected]"; Command myMoveMailbox = new Command("Move-Mailbox", false, false); myMoveMailbox.Parameters.Add("Identity", mbxOwner); myMoveMailbox.Parameters.Add("TargetDatabase", targetDatabase); myMoveMailbox.Parameters.Add("Verbose"); myMoveMailbox.Parameters.Add("ValidateOnly"); myMoveMailbox.Parameters.Add("Confirm", false); pipeline.Commands.Add(myMoveMailbox); System.Collections.ObjectModel.Collection output = null; // these next few lines that are commented out are where I've tried // registering for events and calling asynchronously but this doesn't // seem to get me anywhere closer // //pipeline.StateChanged += new EventHandler(pipeline_StateChanged); //pipeline.Output.DataReady += new EventHandler(Output_DataReady); //pipeline.InvokeAsync(); //pipeline.Input.Close(); //return; tried these variations that are commented out but none seem to be useful output = pipeline.Invoke(); // Check for errors in the pipeline and throw an exception if necessary if (pipeline.Error != null && pipeline.Error.Count 0) { StringBuilder pipelineError = new StringBuilder(); pipelineError.AppendFormat("Error calling Test() Cmdlet. "); foreach (object item in pipeline.Error.ReadToEnd()) pipelineError.AppendFormat("{0}\n", item.ToString()); throw new Exception(pipelineError.ToString()); } foreach (PSObject psObject in output) { // blah, blah, blah // this is normally where I would read details about a particular PS command // but really pertains to a command once it finishes and has nothing to do with // the verbose messages that I'm after... since this part of the methods pertains // to the after-effects of a command having run, I'm suspecting I need to look to // the asynch invoke method but am not certain or knowing how. } } finally { runspace.Close(); } Thanks!

Getting the constructor of an Interface Type through reflection, is there a better approach than loo

- by Will Marcouiller

I have written a generic type: IDirectorySource<T> where T : IDirectoryEntry, which I'm using to manage Active Directory entries through my interfaces objects: IGroup, IOrganizationalUnit, IUser. So that I can write the following: IDirectorySource<IGroup> groups = new DirectorySource<IGroup>(); // Where IGroup implements `IDirectoryEntry`, of course.` foreach (IGroup g in groups.ToList()) { listView1.Items.Add(g.Name).SubItems.Add(g.Description); } From the IDirectorySource<T>.ToList() methods, I use reflection to find out the appropriate constructor for the type parameter T. However, since T is given an interface type, it cannot find any constructor at all! Of course, I have an internal class Group : IGroup which implements the IGroup interface. No matter how hard I have tried, I can't figure out how to get the constructor out of my interface through my implementing class. [DirectorySchemaAttribute("group")] public interface IGroup { } internal class Group : IGroup { internal Group(DirectoryEntry entry) { NativeEntry = entry; Domain = NativeEntry.Path; } // Implementing IGroup interface... } Within the ToList() method of my IDirectorySource<T> interface implementation, I look for the constructor of T as follows: internal class DirectorySource<T> : IDirectorySource<T> { // Implementing properties... // Methods implementations... public IList<T> ToList() { Type t = typeof(T) // Let's assume we're always working with the IGroup interface as T here to keep it simple. // So, my `DirectorySchema` property is already set to "group". // My `DirectorySearcher` is already instantiated here, as I do it within the DirectorySource<T> constructor. Searcher.Filter = string.Format("(&(objectClass={0}))", DirectorySchema) ConstructorInfo ctor = null; ParameterInfo[] params = null; // This is where I get stuck for now... Please see the helper method. GetConstructor(out ctor, out params, new Type() { DirectoryEntry }); SearchResultCollection results = null; try { results = Searcher.FindAll(); } catch (DirectoryServicesCOMException ex) { // Handling exception here... } foreach (SearchResult entry in results) entities.Add(ctor.Invoke(new object() { entry.GetDirectoryEntry() })); return entities; } } private void GetConstructor(out ConstructorInfo constructor, out ParameterInfo[] parameters, Type paramsTypes) { Type t = typeof(T); ConstructorInfo[] ctors = t.GetConstructors(BindingFlags.CreateInstance | BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.InvokeMethod); bool found = true; foreach (ContructorInfo c in ctors) { parameters = c.GetParameters(); if (parameters.GetLength(0) == paramsTypes.GetLength(0)) { for (int index = 0; index < parameters.GetLength(0); ++index) { if (!(parameters[index].GetType() is paramsTypes[index].GetType())) found = false; } if (found) { constructor = c; return; } } } // Processing constructor not found message here... } My problem is that T will always be an interface, so it never finds a constructor. Is there a better way than looping through all of my assembly types for implementations of my interface? I don't care about rewriting a piece of my code, I want to do it right on the first place so that I won't need to come back again and again and again. EDIT #1 Following Sam's advice, I will for now go with the IName and Name convention. However, is it me or there's some way to improve my code? Thanks! =)

Issue getting camera emulation to work with Tom G's HttpCamera

- by user591524

I am trying to use the android emulator to preview video from webcam. I have used the tom gibara sample code, minus the webbroadcaster (i am instead using VLC streaming via http). So, I have modified the SDK's "CameraPreview" app to use the HttpCamera, but the stream never appears. Debugging through doesn't give me any clues either. I wonder if anything obvious is clear to others? The preview app launches and remains black. Notes: 1) I have updated the original CameraPreview class as described here: http://www.inter-fuser.com/2009/09/live-camera-preview-in-android-emulator.html, but referencing httpCamera instead of socketcamera. 2) I updated Tom's original example to reference "Camera" type instead of deprecated "CameraDevice" type. 3) Below is my CameraPreview.java. 4) THANK YOU package com.example.android.apis.graphics; import android.app.Activity; import android.content.Context; import android.hardware.Camera; import android.os.Bundle; import android.view.SurfaceHolder; import android.view.SurfaceView; import android.view.Window; import java.io.IOException; import android.graphics.Canvas; // ---------------------------------------------------------------------- public class CameraPreview extends Activity { private Preview mPreview; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Hide the window title. requestWindowFeature(Window.FEATURE_NO_TITLE); // Create our Preview view and set it as the content of our activity. mPreview = new Preview(this); setContentView(mPreview); } } // ---------------------------------------------------------------------- class Preview extends SurfaceView implements SurfaceHolder.Callback { SurfaceHolder mHolder; //Camera mCamera; HttpCamera mCamera;//changed Preview(Context context) { super(context); // Install a SurfaceHolder.Callback so we get notified when the // underlying surface is created and destroyed. mHolder = getHolder(); mHolder.addCallback(this); //mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); mHolder.setType(SurfaceHolder.SURFACE_TYPE_NORMAL);//changed } public void surfaceCreated(SurfaceHolder holder) { // The Surface has been created, acquire the camera and tell it where // to draw. //mCamera = Camera.open(); this.StartCameraPreview(holder); } public void surfaceDestroyed(SurfaceHolder holder) { // Surface will be destroyed when we return, so stop the preview. // Because the CameraDevice object is not a shared resource, it's very // important to release it when the activity is paused. //mCamera.stopPreview();//changed mCamera = null; } public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { // Now that the size is known, set up the camera parameters and begin // the preview. //Camera.Parameters parameters = mCamera.getParameters(); //parameters.setPreviewSize(w, h); //mCamera.setParameters(parameters); //mCamera.startPreview(); this.StartCameraPreview(holder); } private void StartCameraPreview(SurfaceHolder sh) { mCamera = new HttpCamera("10.213.74.247:443", 640, 480, true);//changed try { //mCamera.setPreviewDisplay(holder); Canvas c = sh.lockCanvas(null); mCamera.capture(c); sh.unlockCanvasAndPost(c); } catch (Exception exception) { //mCamera.release(); mCamera = null; // TODO: add more exception handling logic here } } }

can a python script know that another instance of the same script is running... and then talk to it?

- by Justin Grant

I'd like to prevent multiple instances of the same long-running python command-line script from running at the same time, and I'd like the new instance to be able to send data to the original insance before the new instance commits suicide. How can I do this in a cross-platform way? Specifically, I'd like to enable the following behavior: "foo.py" is launched from the command line, and it will stay running for a long time-- days or weeks until the machine is rebooted or the parent process kills it. every few minutes the same script is launched again, but with different command-line parameters when launched, the script should see if any other instances are running. if other instances are running, then instance #2 should send its command-line parameters to instance #1, and then instance #2 should exit. instance #1, if it receives command-line parameters from another script, should spin up a new thread and (using the command-line parameters sent in the step above) start performing the work that instance #2 was going to perform. So I'm looking for two things: how can a python program know another instance of itself is running, and then how can one python command-line program communicate with another? Making this more complicated, the same script needs to run on both Windows and Linux, so ideally the solution would use only the Python standard library and not any OS-specific calls. Although if I need to have a Windows codepath and an *nix codepath (and a big if statement in my code to choose one or the other), that's OK if a "same code" solution isn't possible. I realize I could probably work out a file-based approach (e.g. instance #1 watches a directory for changes and each instance drops a file into that directory when it wants to do work) but I'm a little concerned about cleaning up those files after a non-graceful machine shutdown. I'd ideally be able to use an in-memory solution. But again I'm flexible, if a persistent-file-based approach is the only way to do it, I'm open to that option. More details: I'm trying to do this because our servers are using a monitoring tool which supports running python scripts to collect monitoring data (e.g. results of a database query or web service call) which the monitoring tool then indexes for later use. Some of these scripts are very expensive to start up but cheap to run after startup (e.g. making a DB connection vs. running a query). So we've chosen to keep them running in an infinite loop until the parent process kills them. This works great, but on larger servers 100 instances of the same script may be running, even if they're only gathering data every 20 minutes each. This wreaks havoc with RAM, DB connection limits, etc. We want to switch from 100 processes with 1 thread to one process with 100 threads, each executing the work that, previously, one script was doing. But changing how the scripts are invoked by the monitoring tool is not possible. We need to keep invocation the same (launch a process with different command-line parameters) but but change the scripts to recognize that another one is active, and have the "new" script send its work instructions (from the command line params) over to the "old" script.

Getting the constructor of an Interface Type through reflection?

- by Will Marcouiller

I have written a generic type: IDirectorySource<T> where T : IDirectoryEntry, which I'm using to manage Active Directory entries through my interfaces objects: IGroup, IOrganizationalUnit, IUser. So that I can write the following: IDirectorySource<IGroup> groups = new DirectorySource<IGroup>(); // Where IGroup implements `IDirectoryEntry`, of course.` foreach (IGroup g in groups.ToList()) { listView1.Items.Add(g.Name).SubItems.Add(g.Description); } From the IDirectorySource<T>.ToList() methods, I use reflection to find out the appropriate constructor for the type parameter T. However, since T is given an interface type, it cannot find any constructor at all! Of course, I have an internal class Group : IGroup which implements the IGroup interface. No matter how hard I have tried, I can't figure out how to get the constructor out of my interface through my implementing class. [DirectorySchemaAttribute("group")] public interface IGroup { } internal class Group : IGroup { internal Group(DirectoryEntry entry) { NativeEntry = entry; Domain = NativeEntry.Path; } // Implementing IGroup interface... } Within the ToList() method of my IDirectorySource<T> interface implementation, I look for the constructor of T as follows: internal class DirectorySource<T> : IDirectorySource<T> { // Implementing properties... // Methods implementations... public IList<T> ToList() { Type t = typeof(T) // Let's assume we're always working with the IGroup interface as T here to keep it simple. // So, my `DirectorySchema` property is already set to "group". // My `DirectorySearcher` is already instantiated here, as I do it within the DirectorySource<T> constructor. Searcher.Filter = string.Format("(&(objectClass={0}))", DirectorySchema) ConstructorInfo ctor = null; ParameterInfo[] params = null; // This is where I get stuck for now... Please see the helper method. GetConstructor(out ctor, out params, new Type() { DirectoryEntry }); SearchResultCollection results = null; try { results = Searcher.FindAll(); } catch (DirectoryServicesCOMException ex) { // Handling exception here... } foreach (SearchResult entry in results) entities.Add(ctor.Invoke(new object() { entry.GetDirectoryEntry() })); return entities; } } private void GetConstructor(out ConstructorInfo constructor, out ParameterInfo[] parameters, Type paramsTypes) { Type t = typeof(T); ConstructorInfo[] ctors = t.GetConstructors(BindingFlags.CreateInstance | BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.InvokeMethod); bool found = true; foreach (ContructorInfo c in ctors) { parameters = c.GetParameters(); if (parameters.GetLength(0) == paramsTypes.GetLength(0)) { for (int index = 0; index < parameters.GetLength(0); ++index) { if (!(parameters[index].GetType() is paramsTypes[index].GetType())) found = false; } if (found) { constructor = c; return; } } } // Processing constructor not found message here... } My problem is that T will always be an interface, so it never finds a constructor. Might somebody guide me to the right path to follow in this situation?

Understanding the value of Customer Experience & Loyalty for the Telecommunications Industry

- by raul.goycoolea

Worried by economic woes and market forces, especially in mature markets, communications service providers (CSPs) increasingly focus on improving customer experience. In fact, it seems difficult to find a major message by a C-level executive in the developed world that does not include something on "meeting and exceeding customers' needs". Frequently in customer satisfaction studies by prominent firms, CSPs fall short of the leadership demonstrated by other industries that take customer-centric approaches to their bottom-line strategies. Consider the following:Despite the continued impact of global economic crisis, in July 2010, Apple Computer posted record revenue and net quarterly profit. Those who attribute the results primarily to the iPhone 4 launch should note that Apple also shipped around 30% more Macintosh computers than the same period the previous year. Even sales of the iPod line increased by 8% in a highly commoditized, shrinking media player market. Finally, Apple began selling iPads during the quarter, with total sales of more than 3 million units. What does Apple have that the others lack? Well, some great products (and services) to be sure, but it also excels at customer service and support, marketing, and distribution, and has one of the strongest brands globally. Its products are useful, simple to use, easy to acquire and augment, high quality, and considered very cool. They also evoke such an emotional response from many of Apple's customers, which they turn up their noses at competitive products.In other words, Apple appears to have mastered virtually every aspect of customer experience and the resultant loyalty of its customer base - even in difficult financial times. Through that unwavering customer focus, Apple continues to drive its revenues and profits to new heights. Other customer loyalty leaders like Wal-Mart, Google, Toyota and Honda are also doing well by focusing on customer experience as an essential driver of profitability. Service providers should note this performance and ask themselves how they might leverage the same principles to increase their own profitability. After all, that is what customer experience and loyalty are all about: profitability.To successfully manage all the critical touch points of customer experience, CSPs must shun the one-size-fits-all approach. They can no longer afford to view customer service fundamentally as an act of altruism - which mentality dates back to the industry's civil service days, when CSPs were typically government organizations that were critical to economic development and public safety.As regulators and public officials have pushed, and continue to push, service providers to new heights of reliability - using incentives and punishments - most CSPs already have some of the fundamental building blocks of customer service in place. Yet despite that history and experience, service providers still lag other industries in providing what is seen as good customer service.As we observed in the TMF's 2009 Insights Research report, Customer Experience Management: Driving Loyalty & Profitability there has been resurgence in interest by CSPs. More and more of them have stated ambitions to catch up other industries, and they are realizing that good customer service is a powerful strategy for increasing business performance and profitability, not an act of good will.CSPs are recognizing the connection between customer experience and profitability, as demonstrated in many studies. For example, according to research by Bain & Company, a 5 percent improvement in customer retention rates can yield as much as a 75 percent increase in profits for companies across a range of industries.After decades of customer experience strategy formulation, Bain partner and business author, Frederick Reichheld, considers "would you recommend us to a friend?" as the ultimate question for a customer. How many times have you or your friends recommended an iPod, iPhone or a Mac? What do your children recommend to their peers? Their peers to them?There are certain steps service providers have to take to create more personalized relationships with their customers, as well as reduce churn and increase profitability, all while becoming leaner and more agile. First, they have to define customer experience, we define it as the result of the sum of observations, perceptions, thoughts and feelings arising from interactions and relationships between customers and their service provider(s). Virtually every customer touch point - whether directly or indirectly linked to service providers and their partners - contributes to customer perception, satisfaction, loyalty, and ultimately profitability. Gaining leadership in customer experience and satisfaction will not be a simple task, as it is affected by virtually every customer-facing aspect of the service provider, and in turn impacts the service provider deeply - especially on the all-important bottom line. The scope of issues affecting customer experience is complex and dynamic.With new services, devices and applications extending the basis of customer experience to domains beyond the direct control of the service provider, it is likely to increase in complexity and dynamism.Customer loyalty = increased profitsAs stated earlier, customer experience programs are not fundamentally altruistic exercises, but a strategic means of improving competitiveness and profitability in the short and long term. Loyalty is essential to deriving long term profits from customers.Some of the earliest loyalty programs date back to the 1930s, when packaged goods companies offered embedded coupons for rewards to buyers, and eventually retail chains began offering reward programs to frequent shoppers. These programs continued for decades but were leapfrogged in the 1980s by more aggressive programs from the airlines.This movement was led by American Airlines, which launched the first full-scale loyalty marketing program of the modern era with the AAdvantage frequent flyer scheme. It was the first to reward frequent fliers with notional air miles that could be accumulated and later redeemed for free travel. Figure 1: Opportunities example of Customer loyalty driven profitOther airlines and travel providers were quick to grasp the incredible value of providing customers with an incentive to use their company exclusively. Within a few years, dozens of travel industry companies launched similar initiatives and now loyalty programs are achieving near-ubiquity in many service industries, especially those in which it is difficult to differentiate offerings by product attributes.The belief is that increased profitability will result from customer retention efforts because:• The cost of acquisition occurs only at the beginning of a relationship: the longer the relationship, the lower the amortized cost;• Account maintenance costs decline as a percentage of total costs, or as a percentage of revenue, over the lifetime of the relationship;• Long term customers tend to be less inclined to switch and less price sensitive which can result in stable unit sales volume and increases in dollar-sales volume;• Long term customers may initiate word-of-mouth promotions and referrals, which cost the company nothing and arguably are the most effective form of advertising;• Long-term customers are more likely to buy ancillary products and higher margin supplemental products;• Long term customers tend to be satisfied with their relationship with the company and are less likely to switch to competitors, making market entry or competitors gaining market share difficult;• Regular customers tend to be less expensive to service, as they are familiar with the processes involved, require less 'education', and are consistent in their order placement;• Increased customer retention and loyalty makes the employees' jobs easier and more satisfying. In turn, happy employees feed back into higher customer satisfaction in a virtuous circle. Figure 2: The virtuous circle of customer loyaltyFigure 2 represents a high-level example of a virtuous cycle driven by customer satisfaction and loyalty, depicting how superiority in product and service offerings, as well as strong customer support by competent employees, lead to higher sales and ultimately profitability. As stated above, this is not a new concept, but succeeding with it is difficult. It has eluded many a company driven to achieve profitability goals. Of course, for this circle to be virtuous, the customer relationship(s) must be profitable.Trying to maintain the loyalty of unprofitable customers is not a viable business strategy. It is, therefore, important that marketers can assess the profitability of each customer (or customer segment), and either improve or terminate relationships that are not profitable. This means each customer's 'relationship costs' must be understood and compared to their 'relationship revenue'. Customer lifetime value (CLV) is the most commonly used metric here, as it is generally accepted as a representation of exactly how much each customer is worth in monetary terms, and therefore a determinant of exactly how much a service provider should be willing to spend to acquire or retain that customer.CLV models make several simplifying assumptions and often involve the following inputs:• Churn rate represents the percentage of customers who end their relationship with a company in a given period;• Retention rate is calculated by subtracting the churn rate percentage from 100;• Period/horizon equates to the units of time into which a customer relationship can be divided for analysis. A year is the most commonly used period for this purpose. Customer lifetime value is a multi-period calculation, often projecting three to seven years into the future. In practice, analysis beyond this point is viewed as too speculative to be reliable. The model horizon is the number of periods used in the calculation;• Periodic revenue is the amount of revenue collected from a customer in a given period (though this is often extended across multiple periods into the future to understand lifetime value), such as usage revenue, revenues anticipated from cross and upselling, and often some weighting for referrals by a loyal customer to others; • Retention cost describes the amount of money the service provider must spend, in a given period, to retain an existing customer. Again, this is often forecast across multiple periods. Retention costs include customer support, billing, promotional incentives and so on;• Discount rate means the cost of capital used to discount future revenue from a customer. Discounting is an advanced method used in more sophisticated CLV calculations;• Profit margin is the projected profit as a percentage of revenue for the period. This may be reflected as a percentage of gross or net profit. Again, this is generally projected across the model horizon to understand lifetime value.A strong focus on managing these inputs can help service providers realize stronger customer relationships and profits, but there are some obstacles to overcome in achieving accurate calculations of CLV, such as the complexity of allocating costs across the customer base. There are many costs that serve all customers which must be properly allocated across the base, and often a simple proportional allocation across the whole base or a segment may not accurately reflect the true cost of serving that customer; This is made worse by the fragmentation of customer information, which is likely to be across a variety of product or operations groups, and may be difficult to aggregate due to different representations.In addition, there is the complexity of account relationships and structures to take into consideration. Complex account structures may not be understood or properly represented. For example, a profitable customer may have a separate account for a second home or another family member, which may appear to be unprofitable. If the service provider cannot relate the two accounts, CLV is not properly represented and any resultant cancellation of the apparently unprofitable account may result in the customer churning from the profitable one.In summary, if service providers are to realize strong customer relationships and their attendant profits, there must be a very strong focus on data management. This needs to be coupled with analytics that help business managers and those who work in customer-facing functions offer highly personalized solutions to customers, while maintaining profitability for the service provider. It's clear that acquiring new customers is expensive. Advertising costs, campaign management expenses, promotional service pricing and discounting, and equipment subsidies make a serious dent in a new customer's profitability. That is especially true given the rising subsidies for Smartphone users, which service providers hope will result in greater profits from profits from data services profitability in future. The situation is made worse by falling prices and greater competition in mature markets.Customer acquisition through industry consolidation isn't cheap either. A North American service provider spent about $2,000 per subscriber in its acquisition of a smaller company earlier this year. While this has allowed it to leapfrog to become the largest mobile service provider in the country, it required a total investment of more than $28 billion (including assumption of the acquiree's debt).While many operating cost synergies clearly made this deal more attractive to the acquiring company, this is certainly an expensive way to acquire customers: the cost per subscriber in this case is not out of line with the prices others have paid for acquisitions.While growth by acquisition certainly increases overall revenues, it often creates tremendous challenges for profitability. Organic growth through increased customer loyalty and retention is a more effective driver of profit, as well as a stronger predictor of future profitability. Service providers, especially those in mature markets, are increasingly recognizing this and taking steps toward a creating a more personalized, flexible and satisfying experience for their customers.In summary, the clearest path to profitability for companies in virtually all industries is through customer retention and maximization of lifetime value. Service providers would do well to recognize this and focus attention on profitable customer relationships.

After creating the table, your create a class in your framework for getting messages with a string key specified. var message = FrameworkMessages.Get("ChangesSavedSuccess"); Everyone would say this code is so error prone, because message keys are not strong-typed, and might create errors in application that are not caught in tests. So we think of a way to make it strong-typed, i.e. create a class to use it like this: var message = Messages.ChangesSavedSuccess; in Messages class the code looks like this: public string ChangesSavedSuccess { get { return FrameworkMessages.Get("ChangesSavedSuccess"); } } And clearly, we are not going to create the Messages class manually; we need a class generator for it. Again assume that the application(s) that intend to use our framework, contain multiple sub-systems. So each sub-system need to have it’s own strong-typed message class that call FrameworkMessages.Get method. So we would like to make our code generator an Item Template so that each developer would easily add the item to his project and no other works would be necessary. Solution We create a T4 Text Template to generate our strong typed class from database. Then create a Visual Studio Item Template with this generator and publish it. What Are T4 Templates You might be already familiar with T4 templates. If it’s so, you can skip this section. T4 Text Template is a fine Visual Studio file type (.tt) that generates output text. This file is a mixture of text blocks and code logic (in C# or VB). For example, you can generate HTML files, C# classes, Resource files and etc with use of a T4 template. Syntax highlighting In Visual Studio 2010 a T4 Template by default will no be syntax highlighted and no auto-complete is supported for it. But there is a fine visual studio extension named ‘Visual T4’ which can be downloaded free from VisualStudioGallery. This tool offers IntelliSense, syntax coloring, validation, transformation preview and more for T4 templates. How Item Templates work in Visual Studio Visual studio extensions allow us to add some functionalities to visual studio. In our case we need to create a .vsix file that adds a template to visual studio item templates. Item templates are zip files containing the template file and a meta-data file with .vstemplate extension. This .vstemplate file is an XML file that provides some information about the template. A .vsix file also is a zip file (renamed to .vsix) that are open with visual studio extension installer. (Re-installing a vsix file requires that old one to be uninstalled from VS: Tools > Extension Manager.) Installing a vsix will need Visual Studio to be closed and re-opened to take effect. Visual studio extension installer will easily find the item template’s zip file and copy it to visual studio’s template items folder. You can find other visual studio templates in [<VS Install Path>\Common7\IDE\ItemTemplates] and you can edit them; but be very careful with VS default templates. How Can I Create a VSIX file 1. Visual Studio SDK depending on your Visual Studio’s version, you need to download Microsoft Visual Studio SDK. Note that if you have VS 2010 SP1, you will need to download and install VS 2010 SP1 SDK; VS 2010 SDK will not be installed (unless you change registry value that indicated your service pack number). Here is the link for VS 2010 SP1 SDK. After downloading, Run it and follow the wizard to complete the installation. 2. Create the file you want to make it an Item Template Create a project (or use an existing one) and add you file, edit it to make it work fine. Back to our own problem, we need to create a T4 (.tt) template. VS-Prok: Add > New Item > General > Text Template Type a file name, ex. Message.tt, and press Add. Create the T4 template file (in this blog I do not intend to include T4 syntaxes so I just write down the code which is clear enough for you to understand) <#@ template debug="false" hostspecific="true" language="C#" #> <#@ output extension=".cs" #> <#@ Assembly Name="System.Data" #> <#@ Import Namespace="System.Data.SqlClient" #> <#@ Import Namespace="System.Text" #> <#@ Import Namespace="System.IO" #> <# var connectionString = "server=Maziar-PC; Database=MyDatabase; Integrated Security=True"; var systemName = "Sys1"; var builder = new StringBuilder(); using (var connection = new SqlConnection(connectionString)) { connection.Open(); var command = connection.CreateCommand(); command.CommandText = string.Format("SELECT [Key] FROM [Message] WHERE System = '{0}'", systemName); var reader = command.ExecuteReader(); while (reader.Read()) { builder.AppendFormat(" public static string {0} {{ get {{ return FrameworkMessages.Get(\"{0}\"); }} }}\r\n", reader[0]); } } #> namespace <#= System.Runtime.Remoting.Messaging.CallContext.LogicalGetData("NamespaceHint") #> { public static class <#= Path.GetFileNameWithoutExtension(Host.TemplateFile) #> { <#= builder.ToString() #> } } As you can see the T4 template connects to a database, reads message keys and generates a class. Here is the output: namespace MyProject.MyFolder { public static class Messages { public static string ChangesSavedSuccess { get { return FrameworkMessages.Get("ChangesSavedSuccess"); } } public static string ErrorSavingChanges { get { return FrameworkMessages.Get("ErrorSavingChanges"); } } } } The output looks fine but there is one problem. The connectionString and systemName are hard coded. so how can I create an flexible item template? One of features of item templates in visual studio is that you can create a designer wizard for your item template, so I can get connection information and system name there. now lets go on creating the vsix file. 3. Create Template In visual studio click on File > Export Template a wizard will show up. if first step click on Item Template on in the combo box select the project that contains Messages.tt. click next. Select Messages.tt from list in second step. click next. In the third step, you should choose References. For this template, System and System.Data are needed so choose them. click next. write down template name, description, if you like add a .ico file as the icon file and also preview image. Uncheck automatically add the templare … . Copy the output location in clip board. click finish. 4. Create VSIX Project In VS, Click File > New > Project > Extensibility > VSIX Project Type a name, ex. FrameworkMessages, Location, etc. The project will include a .vsixmanifest file. Fill in fields like Author, Product Name, Description, etc. In Content section, click on Add Content. choose content type as Item Template. choose source as file. remember you have the template file address in clipboard? now paste it in front of file. click OK. 5. Build VSIX Project That’s it, build the project and go to output directory. You see a .vsix file. you can run it now. After restarting VS, if you click on a project > Add > New Item, you will see your item in list and you can add it. When you add this item to a project, if it has not references to System and System.Data they will be added. but the problem mentioned in step 2 is seen now. 6. Create Design Wizard for your Item Template Create a project i.e. Windows Application named ‘Framework.Messages.Design’, but better change its output type to Class Library. Add References to Microsoft.VisualStudio.TemplateWizardInterface and envdte Add a class Named MessagesDesigner in your project and Implement IWizard interface in it. This is what you should write: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.VisualStudio.TemplateWizard; using EnvDTE; namespace Framework.Messages.Design { class MessageDesigner : IWizard { private bool CanAddProjectItem; public void RunStarted(object automationObject, Dictionary<string, string> replacementsDictionary, WizardRunKind runKind, object[] customParams) { // Prompt user for Connection String and System Name in a Windows form (ShowDialog) here // (try to provide good interface) // if user clicks on cancel of your windows form return; string connectionString = "connection;string"; // Set value from the form string systemName = "system;name"; // Set value from the form CanAddProjectItem = true; replacementsDictionary.Add("$connectionString$", connectionString); replacementsDictionary.Add("$systemName$", systemName); } public bool ShouldAddProjectItem(string filePath) { return CanAddProjectItem; } public void BeforeOpeningFile(ProjectItem projectItem) { } public void ProjectFinishedGenerating(Project project) { } public void ProjectItemFinishedGenerating(ProjectItem projectItem) { } public void RunFinished() { } } } before your code runs replacementsDictionary contains list of default template parameters. After that, two other parameters are added. Now build this project and copy the output assembly to [<VS Install Path>\Common7\IDE] folder. your designer is ready. The template that you had created is now added to your VSIX project. In windows explorer open your template zip file (extract it somewhere). open the .vstemplate file. first of all remove <ProjectItem SubType="Code" TargetFileName="$fileinputname$.cs" ReplaceParameters="true">Messages.cs</ProjectItem> because the .cs file is not to be intended to be a part of template and it will be generated. change value of ReplaceParameters for your .tt file to true to enable parameter replacement in this file. now right after </TemplateContent> end element, write this: <WizardExtension> <Assembly>Framework.Messages.Design</Assembly> <FullClassName>Framework.Messages.Design.MessageDesigner</FullClassName> </WizardExtension> one other thing that you should do is to edit your .tt file and remove your .cs file. Lines 8 and 9 of your .tt file should be: var connectionString = "$connectionString$"; var systemName = "$systemName$"; this parameters will be replaced when the item is added to a project. Save the contents to a zip file with same file name and replace the original file. now again build your VSIX project, uninstall your extension. close VS. now run .vsix file. open vs, add an item of type messages to your project, bingo, your wizard form will show up. fill the fields and click ok, values are replaced in .tt file added. that’s it. tried so hard to make this post brief, hope it was not so long… Cheers Maziar

BES Express - configure MDS to push messages from 3rd party web application

- by Max Gontar

Hi! I have developed IIS web service to send PAP messages using Blackberry Push API over MDS. And there is an application installed on device, configured to receive push messages on appropriate port. Everything works well on MDS simulator. But it's not working well in real environment: I have installed BES Express and register several devices. I can browse MDS url with appropriate port, so url is correct. Also port enabled for reliable pushes is used in push message and in device application. Here is MDS simulator log: <2011-01-12 14:00:03.456 EET>:[272]:<MDS-CS_MDS>:<DEBUG>:<LAYER = SCM, EVENT = PapServlet: request from 0:0:0:0:0:0:0:1 564 bytes...> <2011-01-12 14:00:03.476
