  • Modal View Does Not Appear in Center in Horizontal Orientation

    - by Sheehan Alam
    I have a UIPresentationFormSheet (contains a textview) that appears in the center of the screen when I am in vertical orientation. When I dismiss the modal view, it disappears fine. When I am in horizontal orientation my modal view does not appear in the center of the screen. I have to dismiss my keyboard for the modal view to appear in the center. [self presentModalViewController:composeTweetController animated:TRUE]; When I dismiss the modal view in horizontal orientation the app automatically switches to vertical orientation. -(void)dismissComposeTweetView{ [self dismissModalViewControllerAnimated:TRUE]; } I want the following to happen: Modal view should appear in the center in horizontal orientation Modal view should disappear without switching to vertical orientation

  • WPF DataGrid: How to set content alignment of RowHeader to 'Center'

    - by Nike
    I use WPF DataGrid. I put a text value in RowHeader and want to set alignment of RowHeader content to 'Center'. I tried this: <toolkit:DataGrid.RowHeaderStyle> <Style TargetType="{x:Type toolkit:Primitives.DataGridRowHeader}"> <Setter Property="HorizontalAlignment" Value="Center"/> <Setter Property="HorizontalContentAlignment" Value="Center"/> </Style> </toolkit:DataGrid.RowHeaderStyle> but it doesn't work. Actually I think that there is TextBlock in RowHeader and I need to set its TextAlignment Property to Center. How can do it?

  • Operating System Widget Side Project

    - by Calpis
    I want to start on a side project and here's my idea: Whenever the user's mouse is pressed down, I want a small ring around the cursor to show up. I'm mainly doing this to learn more about programming and get myself to think outside of work related materials. My questions are: 1) is there a good source I can reference to start a project that deals with something like this? 2) Is visual studio a sufficient software to create such an application? Or would I need some other tool to do this. 3) What language should I choose to do this task? Thanks in advance!

  • Center text inside a circle on a canvas

    - by jax
    I have the coordinates of the center of a circle where I need to draw some text. The circle may be larger or smaller depending on the attributes I have specified. I have set the center horizontally using mTextBrush.setTextAlign(Align.CENTER);. The problem is that I can't figure out a way to center the text vertically. (See "Draw the counter" below) //Text Brush setup mTextBrush = new Paint(Paint.ANTI_ALIAS_FLAG); mTextBrush.setColor(Color.BLACK); mTextBrush.setTextSize(1/10*mMaxSize); mTextBrush.setTextAlign(Align.CENTER); mTextBrush.setStyle(Paint.Style.STROKE); private void drawSmallTimer(Canvas canvas) { //Variable cache int radiusLocalCache = this.mRadius; int cx = radiusLocalCache+(radiusLocalCache/2); int cy = radiusLocalCache-(radiusLocalCache/2); int radius = radiusLocalCache/3; //Draw the background circle canvas.drawCircle(cx, cy, radius, mBackgroundBrush); //Draw the outline stroke canvas.drawCircle(cx, cy, radius, mStrokeBrush); //Draw the counter String text = String.valueOf(mCounter); canvas.drawText(text, cx, cy, mTextBrush); }

  • Scaling vectors from a center point?

    - by user146780
    I'm trying to figure out if I have points that make for example a square: * * * * and let's say I know the center of this square. I want a formula that will make it for eample twice its size but from the center * * * * * * * * Therefore the new shape is twice as large and from the center of the polygon. It has to work for any shape not just squares. I'm looking more for the theory behind it more than the implementation. Thanks

  • How to set up a mini call center?

    - by Ralph
    I'm trying to figure out how to set up a miniature call center for a small business. Like, for 1-4 people to take calls, but hopefully expandable to more. We want to accept nation-wide calls, and then I guess distribute the calls among the available agents. If no one is available, I guess it should either put them in a queue and play some annoying music for them, or forward to call to an agent who has least-recently taken a call who can then quickly answer and say "please hold" until they're done their call. We want to have one phone number that customers can call. I guess we then need some kind of ACD system which would take each call and forward it to an agent based on some algorithm? Then we would need to purchase a separate phone line for each agent, plus one just for the distributor? Or do we need several "extra" lines to maintain a queue (one for each customer waiting too)? This "ACD" thing, is it just a device that you would plug a phone line into (or several?), and maybe connect to a computer, aided by some software? Or is a subscription thing that I would need from my local telephone provider? Next, the business we're running, the callers will be repeat customers. It would be helpful to automatically pull up their profile based on the incoming number. The "software" our agents will be running will just be a website where they can log in (preferably from home) and then enter some information they would obtain through the call. So, the system would have to somehow interface with the website if possible. If not, we'll just have to ask each customer for an identifier (phone number, username, customer number, or something). Is this possible? I guess each computer would need a device that the call would pass through, and then if I can somehow hook into that, then I can write some software that will interface with the site. So, where do I start? What hardware do we need to buy? What subscriptions do we need? We were thinking this magicJack might help us in accepting long-distance calls for cheaper, but my understanding is that they provide you with some weird-looking number, is there a way we could "mask" it with our toll-free number? And then pass the incoming calls through the distributor system, which would then get passed to the call-accepting device which would both allow an agent to answer the call and have a software hook? (I realize this might be partially out of the scope of SU, but I wasn't sure where else to ask. It is about computer(-aided) hardware and software anyway.) P.S.: I don't need any of that "press 1 to talk to..." or "say xyz to..." junk. Just a straight-forward, connect-to-next-available-agent system.

  • any software for managing data center, incidents, SLAs?

    - by coderwhiz
    I have been looking in using OTRS - ITSM to manage all of our services but wanted to know if any software existed that is not built into a ticket system? Pretty much want to add all services and tie them to an SLA. Once that is done, we would manually declare incidents and the system would automatically send our notificaton to the proper e-mail lists for downtime/planned maintenance. Would be nice if it calculates reports for SLAs etc. thanks

  • .NET Framework 4.0 mysteriously loses track of System.EnterpriseServices

    - by Lorin Thwaits
    The GAC in .NET 4.0 is cut into two parts now -- one half for .NET Framework 2.0 stuff, and the other for v4.0 stuff. When compiling any project, targeting .NET 2.0, 3.5, or what have you, this annoying error may pop up: Could not load file or assembly 'System.EnterpriseServices, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. In that case, open a run box and perform this copy command: xcopy %ProgramFiles%\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.EnterpriseServices.dll %windir%\Microsoft.NET\assembly\GAC_32\System.EnterpriseServices\v4.0_4.0.0.0__b03f5f7f11d50a3a /e This reconstructs the proper portion of the GAC for that one missing file.

  • Visual Studio confused when there are multiple system.web sections in your web.config

    - by Jeff Widmer
    I am trying to start debugging in Visual Studio for the website I am currently working on but Visual Studio is telling me that I have to enable debugging in the web.config to continue: But I clearly have debugging enabled: At first I chose the option to Modify the Web.config file to enable debugging but then I started receiving the following exception on my site: HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Config section 'system.web/compilation' already defined. Sections must only appear once per config file. See the help topic <location> for exceptions   So what is going on here?  I already have debug=”true”, Visual Studio tells me I do not, and then when I give Visual Studio permission to fix the problem, I get a configuration error. Eventually I tracked it down to having two <system.web> sections. I had defined customErrors higher in the web.config: And then had a second system.web section with compilation debug=”true” further down in the web.config.  This is valid in the web.config and my site was not complaining but I guess Visual Studio does not know how to handle it and sees the first system.web, does not see the debug=”true” and thinks your site is not set up for debugging. To fix this so that Visual Studio was not going to complain, I removed the duplicate system.web declaration and moved the customErrors statement down.

  • SSIS Catalog, Windows updates and deployment failures due to System.Core mismatch

    - by jamiet
    This is a heads-up for anyone doing development on SSIS. On my current project where we are implementing a SQL Server Integration Services (SSIS) 2012 solution we recently encountered a situation where we were unable to deploy any of our projects even though we had successfully deployed in the past. Any attempt to use the deployment wizard resulted in this error dialog: The text of the error (for all you search engine crawlers out there) was: A .NET Framework error occurred during execution of user-defined routine or aggregate "create_key_information": System.IO.FileLoadException: Could not load file or assembly 'System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) ---> System.IO.FileLoadException: The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) System.IO.FileLoadException: System.IO.FileLoadException:     at Microsoft.SqlServer.IntegrationServices.Server.Security.CryptoGraphy.CreateSymmetricKey(String algorithm)    at Microsoft.SqlServer.IntegrationServices.Server.Security.CryptoGraphy.CreateKeyInformation(SqlString algorithmName, SqlBytes& key, SqlBytes& IV) . (Microsoft SQL Server, Error: 6522) After some investigation and a bit of back and forth with some very helpful members of the SSIS product team (hey Matt, Wee Hyong) it transpired that this was due to a .Net Framework fix that had been delivered via Windows Update. I took a look at the server update history and indeed there have been some recently applied .Net Framework updates: This fix had (in the words of Matt Masson) “somehow caused a mismatch on System.Core for SQLCLR” and, as you may know, SQLCLR is used heavily within the SSIS Catalog. The fix was pretty simple – restart SQL Server. This causes the assemblies to be upgraded automatically. If you are using Data Quality Services (DQS) you may have experienced similar problems which are documented at Upgrade SQLCLR Assemblies After .NET Framework Update. I am hoping the SSIS team will follow-up with a more thorough explanation on their blog soon. You DBAs out there may be questioning why Windows Update is set to automatically apply updates on our production servers. We’re checking that out with our hosting provider right now You have been warned! @Jamiet

  • Poor System performance on my machine running Ubuntu 12.04(Beta 2 updated to the present moment)

    - by Mohammad Kamil Nadeem
    Why is it that my system dies when multitasking(it is happening from 11.10) on Ubuntu11.10(Unity), Kubuntu 11.10(KDE) and Deepin Linux which is based on 11.10(Gnome-Shell) The thing is that I thought with 12.04 I would get performance like I used to get on 11.04 on which everything used to run fine without any lag or hiccups. The same lagging(Browser starts to stutter, increased delay in the launching of dash and applications)is happening on 12.04 http://i.imgur.com/YChKB.png and http://i.imgur.com/uyXLA.png . I believe that my system configuration is sufficient for running Ubuntu as you can check here http://paste.ubuntu.com/929734/ . I had the Google voice and chat plugin installed on 12.04 so someone suggested that I should remove that and see if the performance improves but no such respite(I am having this on multiple operating system based on Ubuntu 11.10 as I have mentioned above). On a friends suggestion Ran Memory Test through Partition Magic and my system passed that fine. One thing more that I would like to know is that why when I have 2Gb Ram and 2.1GB swap does my system starts lag and run poorly when Ram consumption goes 500+. If you require anymore information I will gladly provide it.

  • Do NOT remove the reference to System.Core from your VS2010 Project

    - by Lee Brandt
    One of the things I routinely do when adding a new class library project, is remove all references and just add them back in as I need them. That is NOT a good idea for Visual Studio 2010. When I DID need System.Core, and went to add it back, this is what I got: "A reference to 'System.Core' could not be added. This component is automatically referenced..." After some Googling I found this article: http://connect.microsoft.com/VisualStudio/feedback/details/525663/cannot-remove-system-core-dll-reference-from-a-vs2010-project It tells you to add it back manually. Here is the part that needs back in the project file. After the last PropertyGroup node, add this node:   <ItemGroup>     <Reference Include="System.Core" />   </ItemGroup> You should be good to go again. Hope this helps.

  • Digital Asset Management System

    - by Prashant
    I am looking for an opensource web-based digital asset management system. My requirements are to create a web based system where users can upload and download .zip, .jpg, .png, .pdf, .doc, .xls etc. media files. Also user management should be there, so that we can create multiple users and accordingly give them permissions. I have found one http://www.resourcespace.org/ but it looks a bit big and complicated. It is fitting to my need but I am looking and researching a bit more to get some good and more easy to use system. If anyone knows such web based system or tool, please share.

  • SQL SERVER – NTFS File System Performance for SQL Server

    - by pinaldave
    Note: Before practicing any of the suggestion of this article, consult your IT Infrastructural Admin, applying the suggestion without proper testing can only damage your system. Question: “Pinal, we have 80 GB of data including all the database files, we have our data in NTFS file system. We have proper backups are set up. Any suggestion for our NTFS file system performance improvement. Our SQL Server box is running only SQL Server and nothing else. Please advise.” When I receive questions which I have just listed above, it often sends me deep thought. Honestly, I know a lot but there are plenty of things, I believe can be built with community knowledge base. Today I need you to help me to complete this list. I will start the list and you help me complete it. NTFS File System Performance Best Practices for SQL Server Disable Indexing on disk volumes Disable generation of 8.3 names (command: FSUTIL BEHAVIOR SET DISABLE8DOT3 1) Disable last file access time tracking (command: FSUTIL BEHAVIOR SET DISABLELASTACCESS 1) Keep some space empty (let us say 15% for reference) on drive is possible (Only on Filestream Data storage volume) Defragement the volume Add your suggestions here… The one which I often get a pretty big debate is NTFS allocation size. I have seen that on the disk volume which stores filestream data, when increased allocation to 64K from 4K, it reduces the fragmentation. Again, I suggest you attempt this after proper testing on your server. Every system is different and the file stored is different. Here is when I would like to request you to share your experience with related to NTFS allocation size. If you do not agree with any of the above suggestions, leave a comment with reference and I will modify it. Please note that above list prepared assuming the SQL Server application is only running on the computer system. The next question does all these still relevant for SSD – I personally have no experience with SSD with large database so I will refrain from comment.
