  • how to udate window controls(NSTextField,NSCheckbox and etc) in binding manually

    - by Amit
    Hi, I am working on an application in which i need to store all the NSObject subclass properties into plist file and then allow users to store it and restore it. We call it profile and it can restore the saved state of all the controls/views on the window in my application. I have completed the storing/Restoring part, but the issue is when i am updating the class properties manually, it is not updating the control state Like checkboxs and others which is bind with the class property. Please let me know how can i update the controls state, if its KVC/KVO updated programatically. Thanks in advance

  • Enable PyGTK Eventbox motion-notify-event while is a Layout child

    - by mkotechno
    I noticed when a Eventbox is added into a Layout some events are missed, this does not happend for example adding it to a Fixed (very similar widget), I tried to restore the event mask in this way with no sucess: import pygtk import gtk def foo(widget, event): print event pygtk.require('2.0') window = gtk.Window(gtk.WINDOW_TOPLEVEL) window.connect('destroy', lambda x: gtk.main_quit()) eventbox = gtk.EventBox() eventbox.connect('button-press-event', foo) # works eventbox.connect('motion-notify-event', foo) # fail eventbox.set_events( gtk.gdk.BUTTON_MOTION_MASK| # restoring missed masks gtk.gdk.BUTTON1_MOTION_MASK| gtk.gdk.BUTTON2_MOTION_MASK| gtk.gdk.BUTTON3_MOTION_MASK) layout = gtk.Layout() image = gtk.image_new_from_file('/home/me/picture.jpg') layout.add(image) eventbox.add(layout) window.add(eventbox) window.show_all() gtk.main() How should I restore the missed event/mask?

  • How to create a backup from SqlAlchemy?

    - by swilliams
    I'm writing a Pylons app, and am trying to create a simple backup system where every table is serialized and tarred up into a single file for an administrator to download, and use to restore the app should something bad happen. I can serialize my table data just fine using the SqlAlchemy serializer, and I can deserialize it fine as well, but I can't figure out how to commit those changes back to the database. In order to serialize my data I am doing this: from myproject.model.meta import Session from sqlalchemy.ext.serializer import loads, dumps q = Session.query(MyTable) serialized_data = dumps(q.all()) In order to test things out, I go ahead and truncation MyTable, and then attempt to restore using serialized_data: from myproject.model import meta restore_q = loads(serialized_data, meta.metadata, Session) This doesn't seem to do anything... I've tried calling a Session.commit after the fact, individually walking through all the objects in restore_q and adding them, but nothing seems to work. What am I missing? Or is there a better way to do what I'm aiming for? I don't want to shell out and directly touch the database, since SqlAlchemy supports different database engines.

  • NHibernate filters don't work with Session.Get

    - by Khash
    I'm trying to implement a Soft-deletable repository. Usually this can be easily done with a Delete Event listener. To filter out the deleted entities, I can add a Where attribute to my class mapping. However, I also need to implement two more methods in the repository for this entity: Restore and Purge. Restore will "undelete" entities and Purge will hard-delete them. This means I can't use Where attribute (since it block out soft-deleted entities to any access) I tried using filters instead. I can create a filter and enable or disable it within session to achieve the same result. But the problem is filters don't have any effect on Session.Get method (they only affect ICriteria based access). Any ideas as to how solve this problem? Thanks

  • "Cannot load ViewState" after dynamic control changed

    - by Emil D
    In my ASP.NET page I have to dynamically choose and load a custom control, depending on the selected value in a dropdownlist.However I encountered the following problem: When the parameters of the dynamically loaded control are changed, and then the selection in the dropdownlist is changed( thus forcing me to load a different dynamic control the next time the page reloads ), I end up with a "Cannot load ViewState" exception.I assume that this happens because the ViewState is trying to restore the parameters of the old control and it doesn't find it. So , is there any way to stop the viewstate from attempting to restore the state of the non-existig control?

  • Restoring a subversion repository to workcopy revision

    - by tinny
    My subversion VM died the other day (host hardware melted) and I had to restore a backed up copy of the vmware server image. The restore went well and the VM is running again on a new host. The problem I have is that my restored repository is at revision 60 but my working copy on my PC is at 66. When I try and commit my working copy I get the following error message. svn: Commit failed (details follow): svn: No such revision 61 What is the best way to force this commit and bring subversion up to the same revision as my working copy? Thanks

  • problem in `delete-directory` with enabled `delete-by-removing-to-trash`

    - by Andreo
    There is a strange behavior of delete-directory function with enabled flag delete-by-removing-to-trash. It deletes files one by one instead of applying move-file-to-trash to the directory. As a result emacs deletes big directories slowly and there are many files in the trash after deleting, so it is impossible to restore the directory. Example: Directory structure: ddd/ ccc/ 1.txt There are three files in the trash after deleting ddd: trash/ ddd/ ccc/ 1.txt instead of one: trash/ ddd/ It is very slow, because emacs traverse directory recursively. I can't restore deleted directory. What i need is exactly the same behavior as of move-file-to-trash. But it should be transparent (i.e. 'D x' in dired mode). How to solve the problem? As a temporary solution i see the making advice function for `delete-directory'.

    - by lgwest
    When I tried to do a simple modification of the "hello android" program that eclipse adt plugin generates I get error and can't get the program to run again even if I restore the file to its original contents. The modification was that I changed a string in strings.xml. the line was: <string name="app_name">Todo List</string> and the app was runnable, then I changed it to <string name="app_name">Todo List1</string> and it was an error: [2010-04-21 23:18:03 - Todo_list] Error in an XML file: aborting build. And a new empty file also showed up called: strings.out.xml And then I can't get the prrogram back into runnable state even if I delete the empyt file and restore the original line, I'm a confused beginner of java, android and eclipse.

  • How much faster are register based architectures than stack architectures?

    - by drozzy
    Studying compilers course, I am left wondering why use registers at all. It is often the case that the caller or callee must save the register value and then restore it. In a way they always end up using the stack anyway. Is creating additional complexity by using registers really worth it? Excuse my ignorance. Update: Please, I know that registers are faster than RAM and other types of cache. My main concern is that one has to "save" the value that is in the register and the "restore" it to. In both cases we are accessing some kind of cache. Would it not be better to use cache in the first place?

  • 3d cube using canvas. Need a little improvement

    - by TimeManx
    I made this 3d cube using the following code Matrix mMatrix = canvas.getMatrix(); canvas.save(); camera.save(); camera.rotateY(-angle); camera.getMatrix(mMatrix); mMatrix.preTranslate(-width, 0); mMatrix.postTranslate(width, 0); canvas.concat(mMatrix); canvas.drawBitmap(bmp1, 0, 0, null); camera.restore(); canvas.restore(); camera.rotateY(90 - angle); camera.getMatrix(mMatrix); mMatrix.preTranslate(-width, 0); mMatrix.postTranslate(width2, 0); canvas.concat(mMatrix); canvas.drawBitmap(bmp2, width, 0, null); This is what it gives But what I need is It's because when Camera rotates the images, some part of the image gets hidden. Like this But I think this can be done.

  • How can I "undelete" a set of documents in CouchDB?

    - by radicand
    I have a large set of documents in a CouchDB database that were just accidentally bulk deleted using _deleted:true. I also have a backup for this set of data that includes their last known good revision and metadata. I need to maintain the same _id, so simple restore with a new _id is not an option. Compaction has not been run and I can access any of these documents via the &rev= url parameter as well as their attachments (which are needed). What I need to do is "restore" these documents to the revision I have on file. Surprisingly, I have come up empty with any queries on how to achieve this. Tips or hacks appreciated.

  • Pgagent startup script (under the postgres user)

    - by Dominique Guardiola
    Hello, I'm trying to make a clean startup script for pgagent I found one here but I don't see how I can change this : if start-stop-daemon --start --quiet --pidfile /var/run/pgagent.pid \ --exec /usr/bin/pgagent "hostaddr=127.0.0.1 dbname=postgres user=postgres \ password=XXXXXXX";then to launch something like this : su - postgres -c /usr/bin/pgagent "hostaddr=127.0.0.1 dbname=postgres user=postgres" in order to avoid to hard-code the PG password in the script. This is possible using the .pgpass file feature. It works when I'm logged under the postgres user. So my only problem left is how to launch this command under the postgres user tried to add --user=postgres in the call, like mentioned here but it does not work.

  • Toyota's Supply Chain "ran too hot"

    - by [email protected]
    The Feb 28th '10 edition of the Economist had a very informative artical (pg.74) on Toyota's over-stretched supply chain pointing out that they were ' the author of most of its own misfortunes".  James Womack is quoted in the piece on Toyota's rapid expansion 'meant working with a lot of unfamiliar suppliers who didn't have a deep understandin of Toyota's culture.  The majority of the problems almost certainly originated not in the Toyota factories but in those of the supppliers'. One purchasing executive said that it started in mid-2008, when the weaker parts of the supply chain were put under great strain. There is a need for visibility but not always there. Firms need transparancy and speed of communications to make sure defective parts and errors dont reach the customer. It concludes with guidance to manufacturers: "It may be safer not to have all your eggs in one basket, but to have maybe 3 suppliers for major components who can benchmark each other' - Toyota was the peerless exemplar, now seen as an awful warning

  • Moving users folder on Windows-7 to another partition - bad idea?

    - by Donat
    Hi, I'd like to re-submit here a question posted by Benjol on Aug 17at 5:57 "Moving users folder on Windows Vista to another partition - bad idea?" (I can't post one than one link until I earn "10 reputation" and removed my "answer" there to post my follow-up questions here). I am anxiously getting ready at long last to to carry out a clean install (using custom install option) from Vista to Windows-7 Home Premium 64bit with the free upgrade I received late October. For my Vista system I successfully set-up last Summer a multi-partitions scheme with Users and Program Data on a a different partition than the operating system (see link below, and its subsequent links in my comment for details). http://tuts4tech.net/2009/08/05/windows-7-move-the-users-and-program-files-directories-to-a-different-partition/comment-page-1/#comment-562 I was planning a similar set-up for windows 7, a little more streamlined, with OS, Program Files on C:, Users and Program Data on D:, and TV media recording on a separate partition. Reading the Question submitted by Benjol, I am second guessing too. Is moving Users and Program Data on a different partition than the default primary partition with OS and Program Files such a good idea? The couple of people I talked to at the official Microsoft Windows 7 booth at CES 2010 gave the same answer to the intention of moving the Users profile folder to another partition. In a nutshell, they all told me that they used to do this in XP and less in Vista but not anymore with Windows 7... "It is stable, after two months still no problem" I had the feeling it was a scripted answer to emphasize how Windows 7 is so stable and efficient... (Will Windows-7 system not become bugged down over the course of several months to a year or two? Only time will tell) Long story short, I share the same view than Benjol expressed with respect to being "able to backup and restore system and user data independently." I just received a 2TB usb2, eSATA external hard drive as a back-up drive, which includes NTI Shadow 4 (4.1.0.150) for back-up solution. I took note of the issue with NTUSER.DAT and I will read more about Volume Shadow Copy Service (VSS) for Windows 7. I am willing to put the effort if placing Users and Program Data on a different partition would allow to restore a fresher OS+Program image when the system gets bugged down. Questions: Is it such a bad idea? What is the "easy route" referred by Benjol in his post? Is it to just relocate folders to another partition using the Folder property tool? (It is not practical for several users and might not provide a straightforward restore process of just OS and Program Files when needed.) I am starting to learn about Windows 7 libraries. Would Windows 7 libraries be another alternative to achieve this? All this reading to decide how to organize the partition scheme for my custom system is starting to be confusing. I apologize for this lengthy Question. It is my first day here on SuperUser and I am just learning how different from a discussion thread it is. Thank you in advance for all your suggestions and comments. Donat

  • TFS 2010 Basic Concepts

In TFS 2010 Installation, First you need to do the Installation and then you have to configure the Installation Feature from the available features. This is bit similar to SharePoint Installation, where you will first do the Installation and then configure the SharePoint Farms. 1) Installation Features available in TFS2010: a) Basic: It is the most compact TFS installation possible. It will install and configure Source Control, Work Item tracking and Build Services only. (SharePoint and Reporting Integration will not be possible). b) Standard Single Server: This is suitable for Single Server deployment of TFS. It will install and configure Windows SharePoint Services for you and will use the default instance of SQL Server. c) Advanced: It is suitable, if you want use Remote Servers for SQL Server Databases, SharePoint Products and Technologies and SQL Server Reporting Services. d) Application Tier Only: If you want to configure high availability for Team Foundation Server in a Load Balanced Environment (NLB) or you want to move Team Foundation Server from one server to other or you want to restore TFS. e) Upgrade: If you want to upgrade from a prior version of TFS. Note: One more important thing to know here about  TFS 2010 Basic is that,  it can be installed on Client Operations Systems(Windows 7 and Windows Vista SP3), Where as  earlier you cannot Install previous version of TFS (2008 and 2005) on client OS. 2) Team Project Collections: Connect to TFS dialog box in TFS 2008:  In TFS 2008, the TFS Server contains a set of Team Projects and each project may or may not be independent of other projects and every checkin gets a ever increasing  changeset ID  irrespective of the team project in which it is checked in and the same applies to work items  also, who also gets unique Work Item Ids.The main problem with this approach was that there are certain things which were impossible to do; those were required as per the Application Development Process. a)      If something has gone wrong in one team project and now you want to restore it back to earlier state where it was working properly then it requires you to restore the Database of Team Foundation Server from the backup you have taken as per your Maintenance plans and because of this the other team projects may lose out on the work which is not backed up. b)       Your company had a merge with some other company and now you have two TFS servers. One TFS Server which you are working on and other TFS server which other company was working and now after the merge you want to integrate the team projects from two TFS servers into one, which is almost impossible to achieve in TFS 2008. Though you can create the Team Projects in one server manually (In Source Control) which you want to integrate from the other TFS Server, but will lose out on History of Change Sets and Work items and others which are very important. There were few more issues of this sort, which were difficult to resolve in TFS 2008. To resolve issues related to above kind of scenarios which were mainly related TFS Maintenance, Integration, migration and Security,  Microsoft has come up with Team Project Collections concept in TFS 2010.This concept is similar to SharePoint Site Collections and if you are familiar with SharePoint Architecture, then it will help you to understand TFS 2010 Architecture easily. Connect to TFS dialog box in TFS 2010: In above dialog box as you can see there are two Team Project Collections, each team project can contain any number of team projects as you can see on right side it shows the two Team Projects in Team Project Collection (Default Collection) which I have chosen. Note: You can connect to only one Team project Collection at a time using an instance of  TFS Team Explorer. How does it work? To introduce Team Project Collections, changes have been done in reorganization of TFS databases. TFS 2008 was composed of 5-7 databases partitioned by subsystem (each for Version Control, Work Item Tracking, Build, Integration, Project Management...) New TFS 2010 database architecture: TFS_Config: It’s the root database and it contains centralized TFS configuration data, including the list of all team projects exist in TFS server. TFS_Warehouse: The data warehouse contains all the reporting data of served by this server (farm). TFS_* : This contains individual team project collection data. This database contains all the operational data of team project collection regardless of subsystem.In additional to this, you will have databases for SharePoint and Report Server. 3) TFS Farms:  As TFS 2010 is more flexible to configure as multiple Application tiers and multiple Database tiers, so it will be more appropriate to call as TFS Farm if you going for multi server installation of TFS. NLB support for TFS application tiers – With TFS 2010: you can configure multiple TFS application tier machines to serve the same set of Team Project Collections. The primary purpose of NLB support is to enable a cleaner and more complete high availability than in TFS 2008. Even if any application tier in the farm fails then farm will automatically continue to work with hardly any indication to end users of a problem. SQL data tiers: With 2010 you can configure many SQL Servers. Each Database can be configured to be on any SQL Server because each Team Project Collection is an independent database. This feature can also be used to load balance databases across SQL Servers.These new capabilities will significantly change the way enterprises manage their TFS installations in the future. With Team Project Collections and TFS farms, you can create a single, arbitrarily large TFS installation. You can grow it incrementally by adding ATs and SQL Servers as needed.
