  • Creating MS Word 2010 Relative Links?

    - by leeand00
    Okay here is what I've tried so far for creating relative links in my MS Word Documents. In my document from the ribbon I select the File tab. I then select Info from the side bar. Click the properties drop down from the right hand column. (a bit difficult to find initially, since it looks like text not a drop down, but it's there). Click Advanced Properties The <document-name>.docx Properties Dialog Appears I enter .\ to specify that I want a relative path for the links in my document. I click OK. I go back into my document select some text and attempt to make a link out of it clicking the Insert tab of the ribbon, and then clicking Hyperlink. I then select a document from the current folder, and strip the full path from it, leaving just the name of the .docx file to which I wish to link. Then I click OK. The link appears, I try to click it using Ctrl+Click. I am informed that the address of the site is not valid. Check the address and try again. What could I possibly be doing wrong here? I just want a relative link. It's so easy in to do this in HTML.

  • Keyboard shortcut for moving a window to another screen

    - by wcoenen
    When working with two (or more screens), a common problem is that launched applications appear on the "wrong" screen. I especially find this annoying when launching a text editor from the command line, because I have to leave the home row with my right hand in order to drag the window to the "right" screen before I can continue typing. Is it possible to define a keyboard shortcut which moves the current application to the other/next screen? Edit: I'm using Windows XP, but it's good to know that the feature already exists in Windows 7. Edit2: I went for the autohotkey script. This adaptation works for me: #q:: WinGetPos, winx, winy,,, A WinGet, mm, MinMax, A WinRestore, A If (winx > 1270) { newx := winx-1270 OutputDebug, Moving left from %winx% to %newx% } else { newx := winx+1270 OutputDebug, Moving right from %winx% to %newx% } WinMove, A,, newx, winy if mm=1 WinMaximize, A Return I did have to make use of the OutputDebug statements and dbgview to discover the proper threshold value 1270 for moving left or right. The exact threshold is especially important when moving maximized windows to the left.

  • Powerpoint not drawing in slide properly...

    - by commradepolski
    So got another issue to post about. I have a user here who uses powerpoint a lot, Office 07 with SP2. When he opens up the presentation, powerpoint opens fine without errors, but does not draw in the main slide properly. So to better explain that, the list on the left hand side, that shows the slides and what order they are in, loads up fine. You can see the slides and the content etc. When you click on a slide, to edit it, it does not draw in on the editing screen. Not really sure how to explain that. The screen where the work on the slide is done, is what is affected. This is a screen shot from my pc not the users. So instead of the screen saying "Click to add title" it would be improperly drawn such that if I were to drag an explorer window across it, it would leave a trail. I have tried reinstalling office, updating it, as well as giving the user a new windows image and nothing has helped. Any help or advice is appreciated.

  • Unable to delete a file or take ownership on Win7x64

    - by Basic
    I'm a developer and as part of the build process, a Microsoft dll is copied to a certain folder. That file copy is now failing as the target can't be overwritten. I decided to delete it by hand (using an admin account but a non-elevated explorer) so browsed to the folder and attempted a delete. This failed (Require permission from the Administrator). The same applies when using an elevated explorer. So I tried Properties-Security-Advanced-Ownership The current owner is showing as Unable to display current owner. I can't take ownership (a simple Access Denied message with no elaboration). Elevated Command Prompt/PowerShell don't help either (both give an Access Denied in their own way). Process explorer shows no open handles on the file. Eventually, I booted to linux and deleted the file but what I'd like to know is what caused it? Security Essentials had no issues with the file. It's digitally signed by MS and the signatures match.

  • Can I use Upstart to start a script which requires the user's X session?

    - by ledneb
    I wrote a script which greps through the output of synclient to determine whether a laptop's touchpad has miraculously turned itself off (Ubuntu seems to /love/ doing this recently) and, if so, turns it back on. The script is something like this: #!/bin/bash while true ; do if [ `synclient | grep -e"TouchpadOff[\s]*1" | wc -l` -ge 1 ] ; then synclient TouchpadOff=0 fi sleep(3) done (I don't have the laptop to hand right now but you get the point! I will update later when I'm at my laptop if that's incorrect) So I tried running this as an upstart script so my touchpad can heal itself without any interaction. But it seems synclient doesn't find the current user's X session when my script is upstart'ed. I tried running it by using something like su -c myscript.sh ledneb in my script stanza, but to no avail. Should I be looking in the direction of /etc/X11/xinit/xinitrc rather than upstart? Is there a proper way to have this script run in the context of the current (or even a hard-coded) user's x session?

  • Server periodically freezing - Help Stabilizing

    - by JonDog
    We run an asp.net/sql server data collection website with a hand full of clients dumping data in and running reports. We moved to a new server (specs below) and have had issues with it freezing and having to reboot it a dozen times over the pass six months. The hosting company has mentioned possible causes (listed below) but cant give a definite answer on what is going wrong. They have offered to reconfigure how ever I like. We have benefited from having a much faster system and really dont want to get rid of the ssd's unless they are the issue. Two possible setup changes that I've talked with them about are also listed below. Any suggestions on what maybe causing the freezing issue as well as suggestion on a new setup would be great. My main questions are: Do SSD generally have problems running the OS & SQL Server on the same RAID Array? and Are the new SSD's still unrefined enough to be running in a production environment? Thanks Current: Xeon Quad Core E3-1270 3.40 Ghz 16 GB DDR3-1333 ECC SDRAM First Hard Drive: 120GB Intel SSD Second Hard Drive: 120GB Intel SSD Third Hard Drive: 120GB Intel SSD Fourth Hard Drive: 120GB Intel SSD SAS 4 Port RAID Card Windows 2012 Standard Edition - 64 Bit MSSQL 2008 Web Edition Possible Causes: Running Sql Server & OS on same RAID Array OS Software Issues Using SSD's CPU Underpowered Not enough RAM Option 1 2x Xeon Quad Core E5-2603 1.80 GHz 16 GB DDR3-1333 ECC SDRAM 1 x 240GB Intel SSD - OS 3 x 1 TB SATA HDD (7200 RPM) - SQL Server SATA 4 Port RAID Card Windows 2012 Standard Edition - 64 Bit Option 2 Dell PowerEdge E3-1270v2 3.5GHz 4 Cores 16 GB DDR3-1600 UDIMM 4 x 128 GB Samsung 840 Pro SSD Add-in H200 (SAS/SATA Controller), 4 Hard Drives - RAID 10 Windows 2012 Standard Edition - 64 Bit

  • IIS 7: launch unique site instance per host name

    - by OlduwanSteve
    Is it possible to configure IIS 7 so that a single site with multiple bindings (or wildcard bindings) will launch a unique instance for each unique host name? To explain why this is desirable, we have an application that retrieves its configuration from a remote system. The behaviour of the application is governed by this configuration and not by the 'web.config'. The application uses its host name as a key to retrieve the configuration. Currently it is a manual process to create an identical IIS site for each instance of the application, differing only by the bindings. My thought, if it were possible, is that it would be nice to have one IIS site that effectively works as a template for an arbitrary number of dynamic sites. Whenever it is accessed by a unique host name a new instance of the site would be launched, and all further requests to that host name would go to that instance just as though I had created the site by hand. I use IIS regularly, but only for fairly straightforward site hosting. I'd like to know if this could be configured with vanilla IIS 7, but would also welcome answers that require a plugin or 3rd party product. Programming/architectural suggestions about changes to the app wouldn't really be appropriate for serverfault.

  • building a debian base image

    - by Michael
    Is there a preferred way to create base images for Debian-based customized installations? We are currently going with multistrap but although it's better than hand-crafted chroot stuff, it still has a lot of edges and corners. Is there a more reliable and less error-prone way to produce a root filesystem of a Debian installation with some additional .debs installed? (I don't want to send out a Debian installer with a preseed file though.) Addendum 1: To clarify things a bit: We are delivering some kind of software appliance to our customers. That is, a debian operating system, with some additional software packages -- both our own and third-party ones -- and some configuration changes. To ease the installation process, we have an installer that does nothing more than partitioning, copying files to the partitions and setting up grub. So it's basically an image-based installer. So we are basically running the debian installation ourselves and just distribute the already installed operating system. The question is about the installation part. I want to have that as easy and robust as possible, and of course, it should be an automated process.

  • Some Portions of Computer Running Slow (Specifically Graphics)

    - by Mike Gates
    I noticed that a few things are running slow today on my Windows 7 laptop. Specifically, they are: Opening and closing windows takes several seconds for the animation to complete. Windows media player opens fine, but the movies are very laggy MMORPG's, such as RuneScape, are extremely laggy When waking my computer from sleep mode, after entering my password, my desktop takes about 3 seconds to fade in Other than those, everything runs at a normal speed. Things I've done that maybe contributed to this problem: Changed the graphics processor (by plugging in/unplugging the charger) [however, no matter how I change the graphics, I'm still getting this lagginess] Installed AdBlock, a Firefox addon [I recently removed it, and I'm still experiencing this problem] Went into Advanced System Settings, Clicked Settings, and unchecked a few visual things (such as the animation for opening and closing windows) [sure, this got rid of the opening/closing windows lag, but I like that little animation - plus that leaves all the other lag problems I'm experiencing] So, does anyone have any ideas/fixes? If so, please respond. Thank you. Some Other Information: I'm on a HP Pavillion dv7 laptop, 4285 Entertainment PC, with: intel CORE i5 inside, ATI Mobility Radeon Premium Graphics, Microsoft DirectX11 Opening and closing of windows: Defined as opening a program (i.e. Firefox) or closing it by hitting the X in the upper-right hand corner. Lately, the animation for opening and closing windows (which is simply either growing from the icon from the taskbar to fill the screen, or shrinking from the screen down towards the icon on the toolbar.) This problem also occurs for minimizing/maximizing windows. Very laggy movies: defined as .avi movie files saved to My Documents which skips several frames per second and seemingly slows down the movie as a whole Extremely laggy games: I tried RuneScape today, and movement in the game was at least 10x slower than it ever has been, even when playing on the lowest detail/graphics Desktop taking 3 seconds to fade in after sleep: in this scenario, I had no other programs running visibly. The computer generally fades to black from the password screen to the desktop in about 1 second, normally. However, it is now taking 3 or more seconds.

  • Comparing 128MB GeForce 8600GT and 512MB Radeon X1650

    - by Synetech inc.
    Hi, I'm trying to determine which is the better of these two video cards: 128MB Nvidia GeForce 8600GT card while the other has a 512MB ATI Radeon X1650 card. Both cards are the upper-level mid-range versions of their respective series. On the one hand, the ATI has substantially more VRAM, but the Nvidia supports D3D 10 and SM4.0 as opposed to D3D 9.0c/SM3.0 that the ATI supports. Also, I have always heard better things about Nvidia cards compared to ATI cards. I'm trying to find some advice on which one is better, but I can't find any actual comparisons or anything for these specific cards (the comparisons I can find are only similar ones like the X1650 Pro or 8600GT PCI-E), so I figure that what I need to know is whether the extra VRAM is that important. Looking at the ATI table and the Nvidia table seems to indicate that the Nvidia is better, but then again, the Nvidia table also says that the GeForce 8600GT is a PCI-E card with at least 256MB even though the card in question is an AGP with 128MB. (:-?) (It looks like the ATI card is not supported in Windows 7 while the Nvidia card is, which I suppose is also a factor, though not quite as immediately relevant as performance.) Any ideas? Thanks a lot.

  • Iptables and system-config-firewall

    - by nivde92
    I had a set of netfilter rules set with iptables, but someone else told me to use system-config-firewall to add a rule for sharing files with Windows. (Samba) This rewrote the iptables rules file and I lost my own custom rules. I have a backup copy, but am having trouble restoring them. Edit: The server is Centos, I already tried to restore the rules with iptables-restore < /root/working.iptables.rules but for some reason the rules don't change. What are you trying to do? Trying to restore the iptable rules that I have in a backup file. What have you tried in order to make it happen? I've tried to modify the iptables file with vim, since the command iptables-restore was no help. What results did you expect? To get the old rules back. What actually happened? Nothing, when I run the command or edit the file by hand the file doesn't change at all. Maybe something else it's overwriting.

  • Create taskbar shortcut to website in Window 7

    - by BJ292
    I'd like to create a shortcut to a website in Windows 7 on the taskbar that is not pinned to the default web browser. Currently if I drag the favicon from the left end of the firefox address bar to the Win 7 taskbar it will pin a shortcut to the firefox browser icon. Similarly if I create a shortcut on the desktop to a website and drag it to the taskbar it will also end up pinned to the firefox icon. The problem with this is to get to that shortcut I have to right click on the firefox icon and then select the pinned shortcut. That is workable for me but I want to do this for a child - so the shortcut needs to be right there on the taskbar as a stand-alone item. There is a workaround that pretty much solves the problem - create a new folder somewhere safe - create the shortcut to the website in the new folder - right click the taskbar and select toolbars - new toolbar - then browse to the folder you created and select it as the new toolbar. The contents of the folder will now appear on the taskbar as shortcuts. You need to drag it from the right hand end of the taskbar into the middle - turn off show titles and show text and make the icon large. I'd call this a 75% solution. Anyone know how to make a web shortcut that looks and operates just like any of the other shortcuts on the taskbar?

  • What is a good alternative to the WPF WebBrowser Control?

    - by VoidDweller
    I have an MDI WPF app that I need to add web content to. At first, great it looks like I have 2 options built into the framework the Frame control and the WebBrowser control. Given that this is an MDI app it doesn't take long to discover that neither of these will work. The WPF WebBrowser control wraps up the IE WebBrowser ActiveX Control which uses the Win32 graphics pipeline. The "Airspace" issue pretty much sums this up as "Sorry, the layouts will not play nice together". Yes, I have thought about taking snapshots of the web content rendering these and mapping the mouse and keyboard events back to the browser control, but I can't afford the performance penalty and I really don't have time to write and thoroughly test it. I have looked for third party controls, but so far I have only found Chris Cavanagh's WPF Chromium Web Browser control. Which wraps up Awesomium 1.5. Together these are very cool, they play nice with the WPF layouts. But they do not meet my performance requirements. They are VERY HEAVY on memory consumption and not to friendly with CPU usage either. Not to mention still quite buggy. I'll elaborate if you are interested. So, do any of you know of a stable performant WPF web browser control? Thanks.

  • Rebinding events in jQuery after Ajax update (updatepanel)

    - by Hojou
    I have several input and option elements on my page, each (well almost) have an event attached to update some text on the page once they change. I use jQuery which is really really cool :) I also use Microsofts Ajax framework, utilizing the UpdatePanel. The reason why I do that is that certain elements are created on the page based on some server-side logic. I don't really want to explain why I use the UpdatePanel - even if it could (it can with quite some effort) be rewritten to use only jQuery I still want that UpdatePanel. You probably guessed it - once I have a postback on the UpdatePanel the jQuery events stops working. I actually was expecting this, since the "postback" is not really a new postback so my code in document.ready that binds the events won't be fired again. I also confirmed my suspicion by reading up on it in the jQuery help libraries. Anyway I'm left with the problem of rebinding my controls after the UpdatePanel is done updating the DOM. I preferably need a solution that does not require adding more .js files (jQuery plug-ins) to the page but something as simple as being able to catch the UpdatePanel's 'afterupdating' where I can just call my method to rebind all the form elements.

  • ImportError: No module named QtWebKit

    - by Hallik
    I am on centos5. I installed python26 source with a make altinstall. Then I did a: yum install qt4 yum install qt4-devel yum install qt4-doc From riverbankcomputing.co.uk I downloaded the source for sip 4.10.2, compiled and installed fine. Then from the same site I downloaded and compiled from source PyQt-x11-4.7.3 Both installs were using the python26 version (/usr/local/bin/python2.6). So configure.py, make, and make install worked with no errors. Finally, I tried to run this script, but got the error in the subject of this post: import sys import signal from PyQt4.QtCore import * from PyQt4.QtGui import * from PyQt4.QtWebKit import QWebPage def onLoadFinished(result): if not result: print "Request failed" sys.exit(1) #screen = QtGui.QDesktopWidget().screenGeometry() size = webpage.mainFrame().contentsSize() # Set the size of the (virtual) browser window webpage.setViewportSize(webpage.mainFrame().contentsSize()) # Paint this frame into an image image = QImage(webpage.viewportSize(), QImage.Format_ARGB32) painter = QPainter(image) webpage.mainFrame().render(painter) painter.end() image.save("output2.png") sys.exit(0) app = QApplication(sys.argv) signal.signal(signal.SIGINT, signal.SIG_DFL) webpage = QWebPage() webpage.connect(webpage, SIGNAL("loadFinished(bool)"), onLoadFinished) webpage.mainFrame().load(QUrl("http://www.google.com")) sys.exit(app.exec_()) Even in the beginning of the configure for pyqt4, I saw it say QtWebKit should be installed, but apparently it's not?

  • "Win32 exception occurred releasing IUnknown at..." error using Pylons and WMI

    - by Anders
    Hi all, Im using Pylons in combination with WMI module to do some basic system monitoring of a couple of machines, for POSIX based systems everything is simple - for Windows - not so much. Doing a request to the Pylons server to get current CPU, however it's not working well, or atleast with the WMI module. First i simply did (something) this: c = wmi.WMI() for cpu in c.Win32_Processor(): value = cpu.LoadPercentage However, that gave me an error when accessing this module via Pylons (GET http://ip:port/cpu): raise x_wmi_uninitialised_thread ("WMI returned a syntax error: you're probably running inside a thread without first calling pythoncom.CoInitialize[Ex]") x_wmi_uninitialised_thread: <x_wmi: WMI returned a syntax error: you're probably running inside a thread without first calling pythoncom.CoInitialize[Ex] (no underlying exception)> Looking at http://timgolden.me.uk/python/wmi/tutorial.html, i wrapped the code accordingly to the example under the topic "CoInitialize & CoUninitialize", which makes the code work, but it keeps throwing "Win32 exception occurred releasing IUnknown at..." And then looking at http://mail.python.org/pipermail/python-win32/2007-August/006237.html and the follow up post, trying to follow that - however pythoncom._GetInterfaceCount() is always 20. Im guessing this is someway related to Pylons spawning worker threads and crap like that, however im kinda lost here, advice would be nice. Thanks in advance, Anders

  • Jquery.get() not returning any data

    - by David Waters
    Hi I am trying to scrape other people web pages (for the forces of good not evil). I am currently trying to do this with javascript/jquery from with in a browser. I am finding that the no data is returned from the jquery.get() success call back function. My code. $.get('http://www.google.co.uk/', function (data, textStatus, XMLHttpRequest){ alert("status " + textStatus); alert('data:' + data); window.data=data; window.textStatus=textStatus; window.httpReq = XMLHttpRequest}); In my mind this should simply do a get on google store the data in window.data and we are all good. What happens is we get textStatus == success and data == "". the status on the XMLHttpRequest is 4(success). I have looked at the network traffic using a transparent proxy (Charles) and everything looks find there http status 200 plenty of data being returned. I am running this just from the Firebug console in Firefox. Any ideas?

  • "cloud architecture" concepts in a system architecture diagrams

    - by markus
    If you design a distributed application for easy scale-out, or you just want to make use of any of the new “cloud computing” offerings by Amazon, Google or Microsoft, there are some typical concepts or components you usually end up using: distributed blob storage (aka S3) asynchronous, durable message queues (aka SQS) non-Relational-/non-transactional databases (like SimpleDB, Google BigTable, Azure SQL Services) distributed background worker pool load-balanced, edge-service processes handling user requests (often virtualized) distributed caches (like memcached) CDN (content delivery network like Akamai) Now when it comes to design and sketch an architecture that makes use of such patterns, are there any commonly used symbols I could use? Or even a download with some cool Visio stencils? :) It doesn’t have to be a formal system like UML but I think it would be great if there were symbols that everyone knows and understands, like we have commonly used shapes for databases or a documents, for example. I think it would be important to not mix it up with traditional concepts like a normal file system (local or network server/SAN), or a relational database. Simply speaking, I want to be able to draw some conclusions about an application’s scalability or data consistency issues by just looking at the system architecture overview diagram. Update: Thank you very much for your answers. I like the idea of putting a small "cloud symbol" on the traditional symbols. However I leave this thread open just in case someone will find specific symbols (maybe in a book or so) - or uploaded some pimped up Visio stencils ;)

  • Stresstesting ASP.NET/IIS with WCAT

    I'm trying to setup a stress/load test using the WCAT toolkit included in the IIS Resources. Using LogParser, I've processed a UBR file with configuration.

Error = 10061 Has anyone in this world ever used WCAT?

  • viewDidLoad not being called by parent UITabBarController

    - by Adam Bishop
    Sample: I've created a minimal set of files that highlight the issue here: http://uploads.omega.org.uk/Foo3.zip If viewDidLoad/viewInitWithNibName are called, a message box is displayed. The message box is not displayed, therefore, the methods are not being called. Details: I have an application that is attempting to use a UITabBarController to switch between multiple views. The views are linked up to the UITabBarController using interface builder (select the tab page, open Attributes (Option-1), and fill in the NIB Name field), and so are displayed "automatically" with no extra code-behind to make them appear. Is it intended behaviour that views loaded like this do not have their viewDidLoad method executed? If not, how am I doing it wrong, and what do I need to change. If it is intended behaviour, I can think of a few work-arounds, but any suggestions are appreciated: Scrap the UITabBarController and implement the view switching myself (using initWithNibName and add/insert/push/Subview). Call each of the children's viewDidLoad method manually in the UITabBarController's own viewDidLoad method. Thank you in advance for any help you can offer.

  • Play mp3 using Python, PyQt, and Phonon

    - by KeyboardInterrupt
    I been trying all day to figure out the Qt's Phonon library with Python. My long term goal is to see if I could get it to play a mms:// stream, but since I can't find an implementation of this done anywhere, I will figure that part out myself. (figured I'd put it out there if anyone knew more about this specifically, if not no big deal.) Anyway, I figured I'd work backwards from a working example I found online. This launches a file browser and will play the mp3 file specified. I wanted to strip out the file browser stuff and get it down to the essentials of executing the script and having it play an Mp3 file with a hardcoded path. I'm assuming my problem is a misunderstanding of setCurrentSource() and specifying the data types. (see: http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/phonon-mediasource.html#fileName) I'm keeping my question kind of broad because ANY help with understanding Phonon would be greatly appreciated. import sys from PyQt4.QtGui import QApplication, QMainWindow, QDirModel, QColumnView from PyQt4.QtGui import QFrame from PyQt4.QtCore import SIGNAL from PyQt4.phonon import Phonon class MainWindow(QMainWindow): m_model = QDirModel() def __init__(self): QMainWindow.__init__(self) self.m_fileView = QColumnView(self) self.m_media = None self.setCentralWidget(self.m_fileView) self.m_fileView.setModel(self.m_model) self.m_fileView.setFrameStyle(QFrame.NoFrame) self.connect(self.m_fileView, SIGNAL("updatePreviewWidget(const QModelIndex &)"), self.play) def play(self, index): self.delayedInit() self.m_media.setCurrentSource( Phonon.MediaSource(self.m_model.filePath(index))) self.m_media.play() def delayedInit(self): if not self.m_media: self.m_media = Phonon.MediaObject(self) audioOutput = Phonon.AudioOutput(Phonon.MusicCategory, self) Phonon.createPath(self.m_media, audioOutput) def main(): app = QApplication(sys.argv) QApplication.setApplicationName("Phonon Tutorial 2 (Python)") mw = MainWindow() mw.show() sys.exit(app.exec_()) if __name__ == '__main__': main()

  • Using FluentValidation with Castle Windsor and Entity Framework 4.0 (POCO) in MVC2

    - by Brian McCord
    This isn't a very simple question, but hopefully someone has run across it. I am trying to get the following things working together: MVC2 FluentValidation Entity Framework 4.0 (POCO) Castle Windsor I've pretty much gotten everything working. I have Castle Windsor implemented and working with the Controllers being served up by the WindsorControllerFactory that is part of MVCContrib. I also have Castle serving up the FluentValidation validators as is described by this article: http://www.jeremyskinner.co.uk/2010/02/22/using-fluentvalidation-with-an-ioc-container/ My problem comes in when I try to use Html.EditorForModel or EditorFor on a view. When I try to do that I get this error message: No component for supporting the service FluentValidation.IValidator`1[[System.Data.Entity.DynamicProxies.State_71C51A42554BA6C3CF05105DA05435AD209602C217FC4C34CA52ACEA2B06B99B, EntityFrameworkDynamicProxies-BrindleyInsurance.BusinessObjects, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]] was found This is due to using the POCO generation on Entity Framework 4.0. At runtime, the generated classes get wrapped with a Dynamic Proxy so tracking and lazy loading can happen. Apparently, when using EditorForModel or EditorFor, it tries to ask Windsor to create a validator for the dynamic proxy type instead of the underlying real type. Does anyone know what I can do to solve this issue?

  • HOW TO: Draggable legend in matplotlib

    - by Adam Fraser
    QUESTION: I'm drawing a legend on an axes object in matplotlib but the default positioning which claims to place it in a smart place doesn't seem to work. Ideally, I'd like to have the legend be draggable by the user. How can this be done? SOLUTION: Well, I found bits and pieces of the solution scattered among mailing lists. I've come up with a nice modular chunk of code that you can drop in and use... here it is: class DraggableLegend: def __init__(self, legend): self.legend = legend self.gotLegend = False legend.figure.canvas.mpl_connect('motion_notify_event', self.on_motion) legend.figure.canvas.mpl_connect('pick_event', self.on_pick) legend.figure.canvas.mpl_connect('button_release_event', self.on_release) legend.set_picker(self.my_legend_picker) def on_motion(self, evt): if self.gotLegend: dx = evt.x - self.mouse_x dy = evt.y - self.mouse_y loc_in_canvas = self.legend_x + dx, self.legend_y + dy loc_in_norm_axes = self.legend.parent.transAxes.inverted().transform_point(loc_in_canvas) self.legend._loc = tuple(loc_in_norm_axes) self.legend.figure.canvas.draw() def my_legend_picker(self, legend, evt): return self.legend.legendPatch.contains(evt) def on_pick(self, evt): if evt.artist == self.legend: bbox = self.legend.get_window_extent() self.mouse_x = evt.mouseevent.x self.mouse_y = evt.mouseevent.y self.legend_x = bbox.xmin self.legend_y = bbox.ymin self.gotLegend = 1 def on_release(self, event): if self.gotLegend: self.gotLegend = False ...and in your code... def draw(self): ax = self.figure.add_subplot(111) scatter = ax.scatter(np.random.randn(100), np.random.randn(100)) legend = DraggableLegend(ax.legend()) I emailed the Matplotlib-users group and John Hunter was kind enough to add my solution it to SVN HEAD. On Thu, Jan 28, 2010 at 3:02 PM, Adam Fraser wrote: I thought I'd share a solution to the draggable legend problem since it took me forever to assimilate all the scattered knowledge on the mailing lists... Cool -- nice example. I added the code to legend.py. Now you can do leg = ax.legend() leg.draggable() to enable draggable mode. You can repeatedly call this func to toggle the draggable state. I hope this is helpful to people working with matplotlib.

  • Perf: Viewing thousands of images in Silverlight 3 on a 3D Wall

    - by Bob Holland
    I currently work on a very cool Silverlight app that displays photos in a 3D wall space like the Wall3D demo that is thrown in with Blend 3. The problem I am currently facing is performance. The app works like this: As you scroll right or left the 3d photo wall rotates As each movement is made, the next column of photos are downloaded, decoded into a BitmapImage and thrown into a 3D Wall Node. As you can imagine users (if you let them) will want to flip through the photos really quickly, but the problem I have is I cannot display the photos quick enough. In most cases it's a beautiful app that works really well, but when an album contains over 300 photos, you can imagine the sort of memory taken up by all the BitmapImage classes and how moving the slider can jump from photo 20 to photo 120 in a second. Of course we have algorithms in place to not download every photo in between, but I still can't work out a fast way to get the photos displayed. It may be a case that we need to throw away the 'great for show' 3D wall and go to a flat DeepZoom like wall like the Playboy archive one that Vertigo did. Still not sure, let me know your thoughts. P.S. We are using Kit3D for all the 3D work, it's using PerspectiveCamera, Model3DGroup, ModelVisual3D, RotateTransform3D & TranslateTransform3D. Cheers, Bob.
