• MSExchangeMailSubmission service is not listed or running; sent mail not working

  - by InterMurph

  I am running a new Exchange 2007 SP1 system. I moved the mailboxes from the old Exchange 2003 server, and incoming mail is working. But outgoing mail is not working at all; even inside my domain. Lots of debugging and searching lead me to believe that the problem is that the "Microsoft Exchange Mail Submission Service" (AKA MSExchangeMailSubmission) is not running. In fact, it's not even listed in the Services list. This document (http://technet.microsoft.com/en-us/library/aa998342.aspx) says that this service is installed by the Mailbox server role. My server is running the Mailbox role, as well as the Hub Transport and Client Access roles. How do I get this service to show up in the list, so that I can start it up? Thanks.

• Should EICAR be updated to test the revision of Antivirus system?

  - by makerofthings7

  I'm posting this here since programmers write viruses, and AV software. They also have the best knowledge of heuristics and how AV systems work (cloaking etc). The EICAR test file was used to functionally test an antivirus system. As it stands today almost every AV system will flag EICAR as being a "test" virus. For more information on this historic test virus please click here. Currently the EICAR test file is only good for testing the presence of an AV solution, but it doesn't check for engine file or DAT file up-to-dateness. In other words, why do a functional test of a system that could have definition files that are more than 10 years old. With the increase of zero day threats it doesn't make much sense to functionally test your system using EICAR. That being said, I think EICAR needs to be updated/modified to be effective test that works in conjunction with an AV management solution. This question is about real world testing, without using live viruses... which is the intent of the original EICAR. That being said I'm proposing a new EICAR file format with the appendage of an XML blob that will conditionally cause the Antivirus engine to respond. X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-EXTENDED-ANTIVIRUS-TEST-FILE!$H+H* <?xml version="1.0"?> <engine-valid-from>2010-1-1Z</engine-valid-from> <signature-valid-from>2010-1-1Z</signature-valid-from> <authkey>MyTestKeyHere</authkey> In this sample, the antivirus engine would only alert on the EICAR file if both the signature or engine file is equal to or newer than the valid-from date. Also there is a passcode that will protect the usage of EICAR to the system administrator. If you have a backgound in "Test Driven Design" TDD for software you may get that all I'm doing is applying the principals of TDD to my infrastructure. Based on your experience and contacts how can I make this idea happen?

• Achieving decoupling in Model classes

  - by Guven

  I am trying to test-drive (or at least write unit tests) my Model classes but I noticed that my classes end up being too coupled. Since I can't break this coupling, writing unit tests is becoming harder and harder. To be more specific: Model Classes: These are the classes that hold the data in my application. They resemble pretty much the POJO (plain old Java objects), but they also have some methods. The application is not too big so I have around 15 model classes. Coupling: Just to give an example, think of a simple case of Order Header - Order Item. The header knows the item and the item knows the header (needs some information from the header for performing certain operations). Then, let's say there is the relationship between Order Item - Item Report. The item report needs the item as well. At this point, imagine writing tests for Item Report; you need have a Order Header to carry out the tests. This is a simple case with 3 classes; things get more complicated with more classes. I can come up with decoupled classes when I design algorithms, persistence layers, UI interactions, etc... but with model classes, I can't think of a way to separate them. They currently sit as one big chunk of classes that depend on each other. Here are some workarounds that I can think of: Data Generators: I have a package that generates sample data for my model classes. For example, the OrderHeaderGenerator class creates OrderHeaders with some basic data in it. I use the OrderHeaderGenerator from my ItemReport unit-tests so that I get an instance to OrderHeader class. The problem is these generators get complicated pretty fast and then I also need to test these generators; defeating the purpose a little bit. Interfaces instead of dependencies: I can come up with interfaces to get rid of the hard dependencies. For example, the OrderItem class would depend on the IOrderHeader interface. So, in my unit tests, I can easily mock the behaviour of an OrderHeader with a FakeOrderHeader class that implements the IOrderHeader interface. The problem with this approach is the complexity that the Model classes would end up having. Would you have other ideas on how to break this coupling in the model classes? Or, how to make it easier to unit-test the model classes?

• Make sniqt recognize all tray abilities (or create a working indicator in Qt)

  - by hakermania

  There is this old thread of mine: How do I create a working indicator with Qt/C++? where I was suggested to use the QSystemTray library for making a tray icon in Ubuntu for my application. Sniqt is a program that takes care of the rest. As known, Ubuntu has got rid of tray icons. Instead, it now uses indicators and only indicators. Sniqt converts the Qt tray icons into working indicators. The problem is that it doesn't do a very decent convertion. Actions like single click, middle click etc do not work, while they do in systems that support tray icons. Is there a way to have these actions back? Can I use QSystemTray icon and still have these interesting (and very helpful, in my occasion) actions in Ubuntu? I would be glad to know the answer to the other thread I talked about earlier (how to make a working indicator using the GTK libraries and prevent the crash), as well.

• How can I open PowerShell via AutoHotkey?

  - by Ryan

  I'm running AutoHotkey 1.0.48.05 on Windows 7. I'd like CTRL-ALT-P to open PowerShell. This is what I have so far: ^!p:: Run %SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe Return This is the error I get: File C:\Users[username]\Documents\WindowsPowerShell\profile.ps1 cannot be loaded because the execution of scripts is disabled on this system. Please see "get-help about_signing" for more details. I've already set the execution policy to RemoteSigned by opening PowerShell ISE as Administrator and running Set-ExecutionPolicy RemoteSigned. (See http://technet.microsoft.com/en-us/library/ee176949.aspx) How can I get around this problem?

• Common SOA Problems by C2B2

  - by JuergenKress

  SOA stands for Service Oriented Architecture and has only really come together as a concrete approach in the last 15 years or so, although the concepts involved have been around for longer. Oracle SOA Suite is based around the Service Component Architecture (SCA) devised by the Open SOA collaboration of companies including Oracle and IBM. SCA, as used in SOA suite, is designed as a way to crystallise the concepts of SOA into a standard which ensures that SOA principles like the separation of application and business logic are maintained. Orchestration or Integration? A common thing to see with many people who are beginning to either build a new SOA based infrastructure, or move an old system to be service oriented, is confusion in the purpose of SOA technologies like BPEL and enterprise service buses. For a lot of problems, orchestration tools like BPEL or integration tools like an ESB will both do the job and achieve the right objectives; however it’s important to remember that, although a hammer can be used to drive a screw into wood, that doesn’t mean it’s the best way to do it. Service Integration is the act of connecting components together at a low level, which usually results in a single external endpoint for you to expose to your customers or other teams within your organisation – a simple product ordering system, for example, might integrate a stock checking service and a payment processing service. Process Orchestration, however, is generally a higher level approach whereby the (often externally exposed) service endpoints are brought together to track an end-to-end business process. This might include the earlier example of a product ordering service and couple it with a business rules service and human task to handle edge-cases. A good (but not exhaustive) rule-of-thumb is that integrations performed by an ESB will usually be real-time, whereas process orchestration in a SOA composite might comprise processes which take a certain amount of time to complete, or have to wait pending manual intervention. BPEL vs BPMN For some, with pre-existing SOA or business process projects, this decision is effectively already made. For those embarking on new projects it’s certainly an important consideration for those using Oracle SOA software since, due to the components included in SOA Suite and BPM Suite, the choice of which to buy is determined by what they offer. Oracle SOA suite has no BPMN engine, whereas BPM suite has both a BPMN and a BPEL engine. SOA suite has the ESB component “Mediator”, whereas BPM suite has none. Decisions must be made, therefore, on whether just one or both process modelling languages are to be used. The wrong decision could be costly further down the line.

• Incident Management-Monitoring Ideas

  - by sprsr

  Hello all, What we are tring to do at our company (banking industry) is to apply some ITIL (Information Technology Infrastructure Library) principles and I need some ideas to develop our incident management system of our company. For those who have experienced with incident management, what are the things that helps you most ? What are the things that you can't live without while managing the incidents. Do you have some good screenshots of such a monitoring software ? Since we choosed to develop our own system instead of buying a big system, there are lots of things we may miss, and we are brainstorming here. I need some key points that most crucial in incident management and monitoring. Thanks.

• Piping the output of a program to Preview.app

  - by Abhay Buch

  I'm using an application (the dot program of the graphviz library) that generates a wide variety of file formats including PostScript and PDF. It can send the result to stdout or to a file. I'm currently sending it to a file and opening it with Preview. Is there any way to pipe the output and have it be read by Preview, so that I'd don't have to generate a file and have it lying around? This is going to be used by a number of people who won't know the internal structure of the generating script and I don't want to clutter their folders or complicate their lives. More generally, is there any way to take a program that sends its output to stdout and pass that output to an program that usually takes it's input from a file, without actually creating a file?

• Sql Table Refactoring Challenge

  Ive been working a bit on cleaning up a large table to make it more efficient.  I pretty much know what I need to do at this point, but I figured Id offer up a challenge for my readers, to see if they can catch everything I have as well as to see if Ive missed anything.  So to that end, I give you my table: CREATE TABLE [dbo].[lq_ActivityLog]( [ID] [bigint] IDENTITY(1,1) NOT NULL, [PlacementID] [int] NOT NULL, [CreativeID] [int] NOT NULL, [PublisherID] [int] NOT NULL, [CountryCode] [nvarchar](10) NOT NULL, [RequestedZoneID] [int] NOT NULL, [AboveFold] [int] NOT NULL, [Period] [datetime] NOT NULL, [Clicks] [int] NOT NULL, [Impressions] [int] NOT NULL, CONSTRAINT [PK_lq_ActivityLog2] PRIMARY KEY CLUSTERED ( [Period] ASC, [PlacementID] ASC, [CreativeID] ASC, [PublisherID] ASC, [RequestedZoneID] ASC, [AboveFold] ASC, [CountryCode] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY] And now some assumptions and additional information: The table has 200,000,000 rows currently PlacementID ranges from 1 to 5000 and should support at least 50,000 CreativeID ranges from 1 to 5000 and should support at least 50,000 PublisherID ranges from 1 to 500 and should support at least 50,000 CountryCode is a 2-character ISO standard (e.g. US) and there is a country table with an integer ID already.  There are < 300 rows. RequestedZoneID ranges from 1 to 100 and should support at least 50,000 AboveFold has values of 1, 0, or 1 only. Period is a date (no time). Clicks range from 0 to 5000. Impressions range from 0 to 5000000. The table is currently write-mostly.  Its primary purpose is to log advertising activity as quickly as possible.  Nothing in the rest of the system reads from it except for batch jobs that pull the data into summary tables. Heres the current information on the database tables size: Design Goals This table has been in use for about 5 years and has performed very well during that time.  The only complaints we have are that it is quite large and also there are occasionally timeouts for queries that reference it, particularly when batch jobs are pulling data from it.  Any changes should be made with an eye toward keeping write performance optimal  while trying to reduce space and improve read performance / eliminate timeouts during read operations. Refactor There are, I suggest to you, some glaringly obvious optimizations that can be made to this table.  And Im sure there are some ninja tweaks known to SQL gurus that would be a big help as well.  Ill post my own suggested changes in a follow-up post for now feel free to comment with your suggestions. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Where should I go to learn about networking? [closed]

  - by Ollie Saunders

  I wonder if anyone could recommend resource or resources such as a good book that: explains how all the important protocols work and interact. I’m interested in those that are relevant in a typical home network and used over the Internet explains in detail how ADSL Internet connections work to the level of depth necessary so that I’m able to tweak and measure performance settings starts from the beginning but attempts to provide proper understanding rather than idiot-oriented steps to follow Basically, I’m interested in how these technologies work and tend to be implemented in hardware and software rather than “here’s what to do if…” I’m interested in Computer Networking by Andrew S. Tanenbaum and I wonder if anyone else has any experience with that title. It’s expensive but I could probably loan a copy for £3 from the library or so.

• Creating Corporate Windows Phone Applications

  - by Tim Murphy

  Most developers write Windows Phone applications for their own gratification and their own wallets.  While most of the time I would put myself in the same camp, I am also a consultant.  This means that I have corporate clients who want corporate solutions.  I recently got a request for a system rebuild that includes a Windows Phone component.  This brought up the questions of what are the important aspects to consider when building for this situation. Let’s break it down in to the points that are important to a company using a mobile application.  The company want to make sure that their proprietary software is safe from use by unauthorized users.  They also want to make sure that the data is secure on the device. The first point is a challenge.  There is no such thing as true private distribution in the Windows Phone ecosystem at this time.  What is available is the ability to specify you application for targeted distribution.  Even with targeted distribution you can’t ensure that only individuals within your organization will be able to load you application.  Because of this I am taking two additional steps.  The first is to register the phone’s DeviceUniqueId within your system.  Add a system sign-in and that should cover access to your application. The second half of the problem is securing the data on the phone.  This is where the ProtectedData API within the System.Security.Cryptography namespace comes in.  It allows you to encrypt your data before pushing it to isolated storage on the device. With the announcement of Windows Phone 8 coming this fall, many of these points will have different solutions.  Private signing and distribution of applications will be available.  We will also have native access to BitLocker.  When you combine these capabilities enterprise application development for Windows Phone will be much simpler.  Until then work with the above suggestions to develop your enterprise solutions. del.icio.us Tags: Windows Phone 7,Windows Phone,Corporate Deployment,Software Design,Mango,Targeted Applications,ProtectedData API,Windows Phone 8

• Languages on a resume: Is it better to put "C/C++" or "C, C++"?

  - by Kevin

  I'm graduating in a couple of weeks, and my resume (as expected) lists the languages that I've had experience with. Previously I've put "C/C++", however back then I didn't have that much experience with these two languages as I do now. Now that I've formally learned these two languages, it has become evident to me (and anyone who really knows these languages) that they are similar, and completely disimilar at the same time. Sure, most C code is compilable C++ code, but syntax and incorporation of library functions is pretty much where these similarities end. In most non-trivial problems, chances are that the desirable C++ solution will be different from the desirable C solution. My question: Will recruiters take note or care about whether you put "C/C++" as opposed to "C, C++"? Will they assume a lack of knowledge of the workings of either because of the inclusion of the first form, or perhaps see the inclusion of the second form as a potential "resume beefer" (listing them as 2 languages, instead of "one")? Furthermore, for jobs that you've applied to that were particularly interested in these two langauges, did the interview process include questions about the differences between C programming and C++ programming (so, about actual programming techniques, not only the extra paradigms in the latter)?

• Cone of Uncertainty in classic and agile projects

  - by DigiMortal

  David Starr from Scrum.org made interesting session in TechEd Europe 2012 - Implementing Scrum Using Team Foundation Server 2012. One of interesting things for me was how Cone of Uncertainty looks like in agile projects (or how agile methodologies distort the cone we know from waterfall projects). This posting illustrates two cones – one for waterfall and one for agile world. Cone of Uncertainty Cone of Uncertainty was introduced to software development community by Steve McConnell and it visualizes how accurate are our estimates over project timeline. Here is the Cone of Uncertainty when we deal with waterfall and Big Design Up-Front (BDUF). Cone of Uncertainty. Taken from MSDN Library page Estimating. The closer we are to project end the more accurate are our estimates. When project ends we know exactly how much every task took time. As we can see then cone is wide when we usually have to give our estimates – it happens somewhere between Initial Project Concept and Requirements Complete. Don’t ask me why Initial Project Concept is the stage where some companies give their best estimates – they just do it every time and doesn’t learn a thing later. This cone is inevitable for software development and agile methodologies that try to make software world better are also able to change the cone. Cone of Uncertainty in agile projects Agile methodologies usually try to avoid BDUF, waterfalls and other things that make all our mistakes highly expensive. Of course, we are not the only ones who make mistakes – don’t also forget our dear customers. Agile methodologies take development as creational work and focus on making it better. One main trick is to focus on small and short iterations. What it means? We are estimating functionalities that are easier for us to understand and implement. Therefore our estimates are more accurate. As we move from few big iterations to many small iterations we also distort and slice Cone of Uncertainty. This is how cone looks when agile methodologies are used. Cone of Uncertainty in agile projects. We have more cones to live with but they are way smaller. I don’t have any numbers to put here because I found any but still this “chart” should give you the point: more smaller iterations cause more but way smaller cones of uncertainty. We can handle these small uncertainties because steps we take to complete small tasks are more predictable and doesn’t grow very often above our heads. One more note. Consider that both of charts given in this posting describe exactly the same phase of same project – just uncertainties are different.

• Why can't tuxboot and ubuntu play well together?

  - by mmr

  I'm trying to get clonezilla to run off of a usb stick, and it seems that the right way to do that is via tuxboot. Tuxboot is not compilable on ubuntu. I used git to get it from the repository, and then when I run the 'install' script (because building it is apparently not allowed, since the build script just tries to install windows things). Qmake-linux wants my qmake executable to be in the same directory as the stuff I pulled down, and let's just say that if there's a way to do this easily, I ain't seein' it. So then I download the linux file, the most recent of which is tuxboot-linux-25. Try to run it, get a failure that libpng12.so.0 isn't found. OK, then I go to install that via the instructions I found on the web but firefox seems to have already deleted from my history (yay!) Then I add the /usr/local/lib directory to ldconfig via emacs (had to install that too, of course): http://ubuntuforums.org/showthread.php?t=369848 I still get the errors that libpng12.so.0 cannot be opened because 'No such file or directory'. ldconfig -p | grep libpng shows that the library is there, but it still doesn't seem to be findable. What to do next? (for the record, doing this in windows is painless-- download, click, and it's done. But I'm trying to be all linuxy and get away from Windows for this...)

• iTunes home sharing problem

  - by Trev

  I have two iMacs running Snow Leopard. I have iTunes home sharing setup on the two of them using the same iTunes account credentials. Up until last night all worked fine... I could download an app on one iMac, then go to the other iMac and drag that app from the home sharing into that iMac's applications. Then all of a sudden it stopped working. I can see and browse the home sharing, however, when I go to drag an app or song from the share to the local library it gives me an error stating that I am unable to do so... when I click OK to this message I lose visibility to the home share. I have checked and this iMac is authorized with my iTunes account and I have even deauthorized and reauthorized but still the same result. Does anyone have any suggestions?

• split large text file without missing data record

  - by Santosh

  I have a 140 MB text file, which contains detail information of books in library. For each book details there is a standard format data details in text file. I need to parse it and insert the data in Database. Here, parsing text file is not an issue. I am facing problem in parsing this large file. So i decided to split the file in small file around 2 MB each file. But i can't manually split this large file in so many pieces. I got HJsplit tool, which split the file but this also doesn't helped as this split the file but 1 book details half part is in one file and rest part is in second file. so if i split this way then information will be missed. How to split the large so that i cant miss the information ? Is there any tool which help me in this condition.

• SCCM for mobile device management returns 404 on /devicemgmt/server.resource

  - by Dan

  We have a new Windows Server 2008 R2 machine onto which we have installed SCCM SP2 followed by the R2 package. We have enabled a mobile device management point and enabled distribution points to support mobile devices as per http://technet.microsoft.com/en-us/library/bb680634.aspx We have also installed the Mobile Device Management Client on to a Windows Mobile 6.1 device. The client on the device fails to connect to the server. Our investigation so far has led us to the URL /devicemgmt/server.resource. However, looking in IIS on the server shows no such URL (in fact nothing apart from the aspnet_client directory) and visiting the URL with a browser returns 404. WebDav is enabled on the Default Web Site in IIS. BITS is installed on the server. Can anyone confirm whether enabling mobile device management will add visible directories to IIS and if so why it might be failing in our case?

• How do i get Safari to ignore the SSL Certificate error?

  - by Tangopop

  In IE 6, 7, 8 and Firefox 3.6.3 and 3.0.5 i have installed a local SSL Certificate on the machine i am testing on and i have gotten the browser to igonre the SSL error (which is off one of my Web Test servers) Now i am tryin to do the same thing within safari 4 and with no luck. Basically i am running some automated scripts to test my website before they go live and i need to be able to ignore these errors as they will all run autonomosly. This is the error screen i am trying to avoid: http://library.bowdoin.edu/news/images/ezproxy-err/safari.jpg As i say i have installed the certificate locally and the IE 7 browser on the same machine works fine.

• My co-worker has not been doing such a good job for the past decade. What do I do? [closed]

  - by stijn

  Possible Duplicate: How do I approach a coworker about his or her code quality? I started working with him almost a decade ago and back then I had never really programmed before, being a young hardware engineer. Right now however I have made quite some progress in all areas being part of software design and i am much, much more skilled than my co-worker who is 15 years older and has been programming more than twice as long. He is super nice and definitely smart enough, but lately his lack of skill and performance are starting to drag me down because we're more and more working on the same codebase. And soon we are going to do a quite ambitious start from scratch creating a whole new hard/software system. I feel it is time to address all issues now, but i do not know how to start. Here are some of the things that I would like to see him improve on: no consistent usage of style, spaces nor tabs (eg if(something ) a =b ) adds newlines around pieces of code to make it easier to read, then commits those with messages like 'no changes made' overall commit messages are useless and so are most of the comments, if there are any (eg 'remove solves for bug Rik' if Rik reported a bug). There is no function/class documentation. lots of spelling errors, in both English and native language, which sometimes are mixed 6/7/8 level deep deep nesting is no exception, a lot of functions start with one level already like if(ptr!=Null){ even when ptr is the result of allocation via new in the constructor numerous source files have over 10k lines of those lines, a major part is simply a result of copy-pasting functionality instead of using a function. This includes copying comments so we end up with 50 occurrences of var=NULL; //TODO TEST this!!!!!!! another part is hundreds of lines of dead code knows what versioning does, yet comments out old code and places new code underneath it when making changes coding skills are below par, especially for the type of rather high precision applications we do. Yet somehow, after a lot of trying and testing, stuff starts to work. But then breaks again some time later because every change casues a waterfall effect. violates every single item in the C++ FAQ lite, practices every bad practice I can think of still doesn't know how to properly use the debugger, but spends hours inspecting messy logfiles in notepad on a tiny laptop screen. Does not make any adjustments to the settings of the software he uses. Never uses keyboard shortcuts. does not seem to progress or learn new things at all. Work rather slow, mostly due to the lack of planning and incorrect usage of tools. How does one deal with this? For starters, how do I make him aware of all these problems? Should I tell the staff about it? And the next step, how to get him to learn new things and adopt another way of working?

• Git for Application Settings

  - by devians

  I use a lot of tools at work and at home, and im constantly tweaking them in one location or the other. It's somewhat common practice for people to use Git to version their .vim, .vimrc, and other . files, since you can host your config files on github and have the share-ability and all the other advantages that implies. Being able to version and branch my configs sounds like a grand idea, since I'm always messing about with them. I'd like to discuss the best practice for doing this on a slightly wider scope. How would you implement it? Have your configfiles repo in ~/Library/Configs or similar, and symlink the appropriate files? How to handle preference files for Applications, ie iTerm2. These files are recreated every time, so you'd have to symlink 'backwards' and put a link in the repo? rather than symlinking to the repo, since it would just delete the symlink.

• Using elapsed time for SlowMo in XNA

  - by Dave Voyles

  I'm trying to create a slow-mo effect in my pong game so that when a player is a button the paddles and ball will suddenly move at a far slower speed. I believe my understanding of the concepts of adjusting the timing in XNA are done, but I'm not sure of how to incorporate it into my design exactly. The updates for my bats (paddles) are done in my Bat.cs class: /// Controls the bat moving up the screen /// </summary> public void MoveUp() { SetPosition(Position + new Vector2(0, -moveSpeed)); } /// <summary> /// Controls the bat moving down the screen /// </summary> public void MoveDown() { SetPosition(Position + new Vector2(0, moveSpeed)); } /// <summary> /// Updates the position of the AI bat, in order to track the ball /// </summary> /// <param name="ball"></param> public virtual void UpdatePosition(Ball ball) { size.X = (int)Position.X; size.Y = (int)Position.Y; } While the rest of my game updates are done in my GameplayScreen.cs class (I'm using the XNA game state management sample) Class GameplayScreen { ........... bool slow; .......... public override void Update(GameTime gameTime, bool otherScreenHasFocus, bool coveredByOtherScreen) base.Update(gameTime, otherScreenHasFocus, false); if (IsActive) { // SlowMo Stuff Elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; if (Slowmo) Elapsed *= .8f; MoveTimer += Elapsed; double elapsedTime = gameTime.ElapsedGameTime.TotalMilliseconds; if (Keyboard.GetState().IsKeyDown(Keys.Up)) slow = true; else if (Keyboard.GetState().IsKeyDown(Keys.Down)) slow = false; if (slow == true) elapsedTime *= .1f; // Updating bat position leftBat.UpdatePosition(ball); rightBat.UpdatePosition(ball); // Updating the ball position ball.UpdatePosition(); and finally my fixed time step is declared in the constructor of my Game1.cs Class: /// <summary> /// The main game constructor. /// </summary> public Game1() { IsFixedTimeStep = slow = false; } So my question is: Where do I place the MoveTimer or elapsedTime, so that my bat will slow down accordingly?
