  • Hell: NTFS "Restore previous versions"...

    - by ttsiodras
    The hell I have experienced these last 24h: Windows 7 installation hosed after bluetooth driver install. Attempting to recover using restore points via "Repair" on the bootable Win7 installation CD. Attempting to go back one day in the restore points. No joy. Attempting to go back two days in the restore points. No joy. Attempting to go back one week in the restore points. Stil no joy. Windows won't boot. Apparently something is REALLY hosed. And then it hits me - PANIC - the restore points somehow reverted DATA files to their older versions! Word, Powerpoint, SPSS, etc document versions are all one week old now. Using the "freshest" restore point. Failed to restore yesterday's restore point!!! I am stuck at old versions of the data!!! Booting KNOPPIX, mounting NTFS partition as read-only under KNOPPIX. Checking. Nope, the data files are still the one week old versions. Booting Win7 CD, Recovery console - Cmd prompt - navigating - yep, data files are still one week old. Removing the drive, mounting it under other Win7 installation. Still old data. Running NTFS undelete on the drive (read-only scan), searching for file created yesterday. Not found. Despair. At this point, idea: I will install a brand new Windows installation, keeping the old one in Windows.old (default behaviour of Windows installs). I boot the new install, I go to my C:\Data\ folder, I choose "Restore previous versions", click on yesterday's date, and click open... YES! It works! I can see the latest versions of my files (e.g. from yesterday). Thank God. And then, I try to view the files under the "yesterday snapshot-version" of c:\Users\MyAccount\Desktop ... And I get "Permission Denied" as soon as I try to open "Users\MyAccount". I make sure I am an administrator. No joy. Apparently, the new Windows installation does not have access to read the "NTFS snapshots" or "Volume Shadow Snapshots" of my old Windows account! Cross-installation permissions? I need to somehow tell the new Windows install that I am the same "old" user... So that I will be able to access the "Users\MyAccount" folder of the snapshot of my old user account. Help?

  • How to genrate a monochrome bit mask for a 32bit bitmap

    - by Mordachai
    Under Win32, it is a common technique to generate a monochrome bitmask from a bitmap for transparency use by doing the following: SetBkColor(hdcSource, clrTransparency); VERIFY(BitBlt(hdcMask, 0, 0, bm.bmWidth, bm.bmHeight, hdcSource, 0, 0, SRCCOPY)); This assumes that hdcSource is a memory DC holding the source image, and hdcMask is a memory DC holding a monochrome bitmap of the same size (so both are 32x32, but the source is 4 bit color, while the target is 1bit monochrome). However, this seems to fail for me when the source is 32 bit color + alpha. Instead of getting a monochrome bitmap in hdcMask, I get a mask that is all black. No bits get set to white (1). Whereas this works for the 4bit color source. My search-foo is failing, as I cannot seem to find any references to this particular problem. I have isolated that this is indeed the issue in my code: i.e. if I use a source bitmap that is 16 color (4bit), it works; if I use a 32 bit image, it produces the all-black mask. Is there an alternate method I should be using in the case of 32 bit color images? Is there an issue with the alpha channel that overrides the normal behavior of the above technique? Thanks for any help you may have to offer! ADDENDUM: I am still unable to find a technique that creates a valid monochrome bitmap for my GDI+ produced source bitmap. I have somewhat alleviated my particular issue by simply not generating a monochrome bitmask at all, and instead I'm using TransparentBlt(), which seems to get it right (but I don't know what they're doing internally that's any different that allows them to correctly mask the image). It might be useful to have a really good, working function: HBITMAP CreateTransparencyMask(HDC hdc, HBITMAP hSource, COLORREF crTransparency); Where it always creates a valid transparency mask, regardless of the color depth of hSource. Ideas?

  • ASP.NET MVC Authorize by Subdomain

    - by Jimmo
    I have what seems like a common issue with SaaS applications, but have not seen this question on here anywhere. I am using ASP.NET MVC with Forms Authentication. I have implemented a custom membership provider to handle logic, but have one issue (perhaps the issue is in my mental picture of the system). As with many SaaS apps, customers create accounts and use the app in a way that looks like they are the only ones present (they only see their items, users, etc.). In reality, there are generic controllers and views presenting data depending on the customer represented in the URL. When calling something like the MembershipProvider.ValidateUser, I have access to the user's customer affiliation in the User object - what I don't have is the context of the request to compare whether it is a data request for the same customer as the user. As an example, One company called ABC goes to abc.mysite.com Another company called XYZ goes to xyz.mysite.com When an ABC user calls http://abc.mysite.com/product/edit/12 I have an [Authorize] attribute on the Edit method in the ProductController to make sure he is signed in and has sufficient permission to do so. If that same ABC user tried to access http://xyz.mysite.com/product/edit/12 I would not want to validate him in the context of that call. In the ValidateUser of the MembershipProvider, I have the information about the user, but not about the request. I can tell that the user is from ABC, but I cannot tell that the request is for XYZ at that point in the code. How should I resolve this?

  • Django sitemap intermittent www

    - by Jen Z
    The automatic sitemap for my Django site fluctuates between including the www on urls and leaving it out (I'm aiming to have it in all the time). This has ramifications in google not indexing my pages properly so I'm trying to narrow down what would be causing this issue. I have set PREPEND_WWW = True and my site record in the sites framework is set to include the www e.g. it's set to www.example.com as opposed to example.com. I'm using memcached but pages should expire from the cache after 48 hours so I wouldn't have thought that would be causing the issue? You can see the problem in effect at http://www.livingspaceltd.co.uk/sitemap.xml (refresh the page a few times). My sitemaps setup is fairly prosaic so I'm doubtful that that is the issue, but in case it's something obvious I'm missing here's the code: ***urls.py*** sitemaps = { 'subpages': Subpages_Sitemap, 'standalone_pages': Standalone_Sitemap, 'categories': Categories_Sitemap, } urlpatterns = patterns('', (r'^sitemap\.xml$', 'django.contrib.sitemaps.views.sitemap', {'sitemaps': sitemaps}), ... ***sitemaps.py*** # -*- coding: utf-8 -*- from django_ls.livingspace.models import Page, Category, Standalone_Page, Subpage from django.contrib.sitemaps import Sitemap class Subpages_Sitemap(Sitemap): changefreq = "monthly" priority = 0.4 def items(self): return Subpage.objects.filter(restricted_to__isnull=True) class Standalone_Sitemap(Sitemap): changefreq = "weekly" priority = 1 def items(self): return Standalone_Page.objects.all() class Categories_Sitemap(Sitemap): changefreq = "weekly" priority = 0.7 def items(self): return Category.objects.all()

  • What causes XP to lose the clipboard?

    - by Steve
    A few times lately I've been getting the error "Cannot open clipboard" when trying to paste. Can I get it back without re-booting? I've been using Arsclip for years as a clipboard enhancement. I'm not convinced that causes the problem as it persists even when I close it.

  • NetBeans parameter fill after code completion

    - by byte
    This is a particularly annoying problem I'm having, and I can't be the only one to have issue with it. In NetBeans, when you type part of a method, then hit CTRL-SPACE, it displays the code-completion popup, whereupon you can hit tab to finish out the word. This is great, and pretty much how all IDE's operate. Example: Thread.sl < CTRL-SPACE Thread.sleep Yay! Problem is that in this context, once you type in a paren, it auto-fills the parameters for the method with their default names, and inserts a closing paren (regardless of whether you have disabled the option to automatically close them on the preferences page for code completion). This behavior is NOT present if you had manually typed out the full name. How is this helpful to anyone? You've got to type over it your actual variable that you will be passing, and NetBeans gives you no option to prevent the closing paren on code-completion. Does anyone have a way to solve this issue, without having to dive into the netbeans source and build it just for this minor of an issue?

  • How to create alternative linux boot without starting some services

    - by rics
    I would like to create an alternative booting possibility in my GRUB menu that does not start some services (listed by chkconfig) like cups. I would use this boot during travel where I surely does not need these services and shorter bootup time is preferable. Permanent removal of such services is not an option because I could not miss them during normal daily work. I use Mandriva 2010 with the latest updates.

  • Name of log file where boot process is logged

    - by ant2009
    Hello, CentOS 5.3 After booting up. I am wondering what is the name of the log file that contains if all services where successfully loaded or not? For example when computer boots you get a list of start services and they can be OK or FAILED. Is there a log file where this information is kept? I had a look in the following directory /var/log/ but not sure which one will contain the informaiton that I need. Many thanks for any advice,

  • Latest Boot Camp drivers for Windows 7

    - by roosteronacid
    I've just recently received my new MacBook Pro, and I've begun exploring Boot Camp; dual-booting Windows 7 Enterprise. I've heard chatter that there are some new Boot Camp drivers--newer than the ones that come with your OSX Show Leopard installation CD. But I'm having a hard time locating them. These updated drivers should fix a few issues with the trackpad, amongst other things. Can you guys point me in the right direction?

  • Will Windows XP work on a Hybrid Hard Drive?

    - by Ben Torell
    I'm looking into getting the Seagate Momentus XT hybrid hard drive, and I'm planning on dual booting between Windows 7 and Windows XP. I know 7 and Vista have native support for taking advantage of the SSD portion of a hybrid drive, and I assume XP does not have any such support, but will XP still work on the drive? I would think it will, but I wanted to be sure, and the Googles are coming up empty for me on this one. Thanks!

  • SIGABRT on iPhone when changing xib

    - by Boz
    I've just finished off an app for the iPhone which, until today, ran fine on the iPhone simulator and actual devices. I tried changing the xib which is loaded in the applicationDidFinishLaunching method in my application delegate class - all I did was change the string in initWithNibName. When I launch the app on the simulator, the Default.png image is shown, then the app crashes with an uncaught exception. When running on a device, the Default.png image is shown for about 10 seconds, the UI is never loaded and I get 'GDB: Program received signal: "SIGABRT".' on the Xcode status bar. Debugging shows that applicationDidFinishLaunching is never actually reached before the app crashes. Setting the starting xib back to the original solves the issue, but now I've made a change and saved it in the Interface Builder and the app shows the same issues as above - I've made no code changes at all. Is this a memory issue, or a known issue of a common mistake? NOTE: I've made no code changes whatsoever, and the only changes I've made to the xib are cosmetic, the IBOutlets are all intact.

  • Guid Primary /Foreign Key dilemma SQL Server

    - by Xience
    Hi guys, I am faced with the dilemma of changing my primary keys from int identities to Guid. I'll put my problem straight up. It's a typical Retail management app, with POS and back office functionality. Has about 100 tables. The database synchronizes with other databases and receives/ sends new data. Most tables don't have frequent inserts, updates or select statements executing on them. However, some do have frequent inserts and selects on them, eg. products and orders tables. Some tables have upto 4 foreign keys in them. If i changed my primary keys from 'int' to 'Guid', would there be a performance issue when inserting or querying data from tables that have many foreign keys. I know people have said that indexes will be fragmented and 16 bytes is an issue. Space wouldn't be an issue in my case and apparently index fragmentation can also be taken care of using 'NEWSEQUENTIALID()' function. Can someone tell me, from there experience, if Guid will be problematic in tables with many foreign keys. I'll be much appreciative of your thoughts on it...

  • Windows 7 Home hangs at "Welcome" screen

    - by White Phoenix
    I'm asking on behalf of a friend who's currently having problems with his machine. Windows 7 Home 32-bit. He's too far away for me to help by going over to his house - I'm helping him over the Internet. This is his current machine: http://www.newegg.com/Product/Product.aspx?Item=N82E16883227134 The only two changes he made to that machine is to swap out the gfx card for a EVGA GTX 460 and the PSU for a Corsair TX650. Here's what happened: He was playing a computer game (fairly CPU/GPU intensive) and had some music going in the background in foobar while playing. Suddenly, he notices the music stopped playing, so he switches to foobar to try to close it, but it freezes up (window won't respond). So he figures it's just foobar having a bad day and force quits that program. Suddenly, his game won't respond, so he force quits that, then the entire computer just went to crap at that point, so he hits the restart button on his machine. Computer POSTS fine, but now he gets stuck at the Windows "welcome" screen (his account is set to auto-login). HD activity light is solid yellow but he doesn't hear HDD activity. He tried booting into Safe Mode - gets stuck at the "welcome screen". Tried a STartup Repair within Windows 7, it found a few problems, but still gets stuck at welcome. I advised him to boot off the DVD - sfc /scannow found nothing (couldn't use the regular /scannow option; says there's a repair pending, had to use use offbootdir/offwindir command switches). Ran startup repair 3 times - found nothing. My friend runs virus/malware scans on a regular basis, so he's fairly sure it's not that either. Right now I'm having my friend run chkdsk /R on the computer while in this Startup Recovery mode - so far it's caught a few bad sectors. However at this point I'm kinda wondering which way to go if chkdsk doesn't fix it. Quick Google search said someone had success by booting Windows with bootlogging on - some others have success with running the aforemented chkdsk, etc. The fact that Windows cannot even boot into Safe Mode concerns me. While we're waiting for chkdsk /R to finish, are there any other options I can give my friend short of reinstalling Windows 7? He has his data on a separate partition so that's not a major problem (though it'll be an annoyance for him). I suspect his hard drive may be having some issues, but my main concern is getting him back up and running before we start diagnosing the hard drive (I may have him run some sort of SMART test utility later).

  • No display on computer due to connection problem

    - by whamsicore
    My computer is booting but has no display. The optical drive has power, but the USB doesn't, so I figured that I had a broken motherboard. However I tried to boot my computer again laying flat, and it worked fine for two seconds, and then froze like it did the first time. It had no display after that. I have come to the conclusion that it is a connection problem (someone had a similar problem on one of the online forums).

  • Dell Inspiron 1525 - internal hard drive not detected

    - by GingerT
    Others have asked about this issue but had intermittent access to their HD, therefore their results did not apply to this situation. I have tried reseating the HD to no effect. I also tried booting from the Internal HD to no effect. Next step get a connector cable and move the data to a different HD, or send in for HD recovery? Any suggestions?

  • Accessing a share point site using the object model.

    - by Prashanth
    Hi I am trying to access a share point site using the SP object model from a console application. I am trying to do something like this.. SPSite site = new SPSite(sitePath) //Operations go here This works fine when the share point site and the console app are on the same machine. However when the console app and the site are on different machines, I get an error "The Web application at "http://server/url" could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application" Here are the things that I have already done: 1) I have tried accessing the site via both IP address as well as machine name, assuming that it could be a DNS resolution issue. 2) Initially I impersonated using a farm admin account, still i could not access. Then I added myself as the farm admin, still no joy. 4) The site is accessible via IE. So it is not a permission issue I guess. 5) I have tried almost all the solutions suggested by various links obtained by googling the error message. I am trying this on share point 2010. A similar issue occurs on 2007 also. Sometimes its kind of frustrating to do SharePoint development , since I get the feeling of stumbling from one error to the next, with no clue as to what could be wrong and the error messages not being helpful in the least :(

  • Android Hero denies XMLSocket or Socket connection? ....errors #2031, #2048

    - by claudi-ursica
    Hi, I am trying to adapt an existing flash web chat application for the Android mobile phone and I am having this really annoying issue. The server is a custom based solution and can send back both binary messages or XML. So I can use either XMLSocket class or the Socket class to get data from the server. Everything works fine when deployed and I connect from the desktop but when I try it from the android mobile I get the infamous errors #2031, followed by #2048. Now the crossdomain.xml file is rock solid and works well for desktop. When the connect socket method runs I see that the server replies with the crossdomain file but I get the error when running on the mobile. Has anyone bumped into this? Is there some limitation from the mobile phone part. I wasn't able to find anything relevant for this issue, in terms of the phone not allowing Socket or XMLSocket connections. The phone(s) Motorola and HTC run Android 2.1 and indicates the flash FL10,1,123,358 version of flash lite. The issue can be reproduced also on the HTC Desire. Any input on this would be highly appreciated... 10x, Claudiu
