• VPN still working after rebooting without client - DrayTek client shows "No Connection"

  - by HeavenCore

  My home network is a simple router + pc's setup, nothing fancy - the router has DHCP enabled for 192.168.0.X (255.255.255.0) and my PC picks up the address 192.168.0.82. There are no devices on my local lan in the 192.168.1.x range. On my pc i have the DrayTek VPN client, and a company i do some work for has a DrayTek Vigor router. The VPN client establishes a VPN to that remote company using an IPSec Tunnel (PreShared Key - no encryption) Last night i shut down my pc with the VPN tunnel still connected, when i turned my computer on this morning i accidentally clicked an RDP shortcut to 192.168.1.2 (a host in the remote company) and to my amazement it connected?!? I checked and the DrayTek VPN client isnt running, and when i did run it, it clearly shows "Status: No connection". confused as to how my machine can still talk to this remote machine i tried a trace: C:\Users\HeavenCore>tracert 192.168.1.2 Tracing route to C4SERVERII [192.168.1.2] over a maximum of 30 hops: 1 * * * Request timed out. 2 * * * Request timed out. 3 * * * Request timed out. 4 * * * Request timed out. 5 * * * Request timed out. 6 * * * Request timed out. 7 * * * Request timed out. 8 * * * Request timed out. 9 * * * Request timed out. 10 * * * Request timed out. 11 * * * Request timed out. 12 15 ms 21 ms 32 ms C4SERVERII [192.168.1.2] Trace complete.

My Question: Can an IPSec tunnel stay up some how after a reboot without use of the VPN client? (well, i can clearly see that it can) - where in windows is there visibility of this? how does my machine know where to route the packets? I appreciate any insights & thoughts!

• What other tool is using my hotkey?

  - by Sammy

  I use Greenshot for screenshots, and it's been nagging about some other software tool using the same hotkey. I started receiving this warning message about two days ago. It shows up each time I reboot and log on to Windows. The hotkey(s) "Ctrl + Shift + PrintScreen" could not be registered. This problem is probably caused by another tool claiming usage of the same hotkey(s)! You could either change your hotkey settings or deactivate/change the software making use of the hotkey(s). What's this all about? The only software I recently installed is CPU-Z Core Temp Speed Fan HD Tune Epson Print CD NetStress What I would like to know is how to find out what other tool is causing this conflict? Do I really have to uninstall each program, one by one, until there is no conflict anymore? I see no option for customizing any hotkeys in CPU-Z, and according to docs there are only a few keyboard shortcuts. These are F5 through F9, but they are no hotkeys. There is nothing in Core Temp, and from what I can see... nothing in Speed Fan. Is any of these programs known to use Ctrl + Shift + PrintScreen hotkey for screenshots? I am actually suspecting the Dropbox client. I think I saw a warning recently coming from Dropbox program, something to do with hotkeys or keyboard shortcuts. I see that it has an option for sharing screenshots under Preferences menu, but I see no option for hotkeys. Core Temp actually also has an option for taking screenshots (F9) but it's just that - a keyboard shortcut, not a hotkey. And again, there's no option actually for changing this setting in Options/Settings menu. How do you resolve this type of conflicts? Are there any general methods you can use to pinpoint the second conflicting software? Like... is there some Windows registry key that holds the hotkeys? Or is it just down to mere luck and trial and error? Addendum I forgot to mention, when I do use the Ctrl + Shift + PrintScreen hotkey, what happens is that the Greenshot context menu shows up, asking me where I want to save the screenshot. So it appears to be working. But I am still getting the darn warning every time I reboot and log on to Windows?! I actually tried changing the key bindings in Greenshot preferences, but after a reboot it seems to have returned back to the settings I had previously. Update I can't see any hotkey conflicts in the Widnows Hotkey Explorer. The aforementioned hotkey is reserved by Greenshot, and I don't see any other program using the same hotkey binding. But when I went into Greenshot preferences, this is what I discovered. As you can see it's the Greenshot itself that uses the same hotkey twice! I guess that's why no other program was listed above as using this hotkey. But how can Greenshot be so stupid to use the same hotkey more than once? I didn't do this! It's not my fault... I'm not that stupid. This is what it's set to right now: Capture full screen: Ctrl + Skift + Prntscrn Capture window: Alt + Prntscrn Capture region: Ctrl + Prntscrn Capture last region: Skift + Prntscrn Capture Internet Explorer: Ctrl + Skift + Prntscrn And this is my preferred setting: Capture full screen: Prntscrn Capture window: Alt + Prntscrn Capture region: Ctrl + Prntscrn Capture last region: Capture Internet Explorer: I don't use any hotkey for "last region" and IE. But when I set this to my liking, as listed here, Greenshot gives me the same warning message, even as I tab through the hotkey entry fields. Sometimes it even gives me the warning when I just click Cancel button. This is really crazy! On the side note... You might have noticed that I have "update check" set to 0 (zero). This is because, in my experience, Greenshot changes all or only some of my preferences back to default settings whenever it automatically updates to a new version. So I opted to stay off updates to get rid of the problem. It has done so for the past three updates or so. I hoped to receive a new update that would fix the issue, but I think it still reverts back to default settings after each update to a new version, including setting default hotkeys. Update 2 I'll give you just one example of how Greenshot behaves. This is the dialog I have in front of me right now. As you can see, I have removed the last two hotkeys and changed the first one to my own liking. While I was clicking in the fields and removing the two hotkeys I was getting the warning message. So let's say I click in the "capture last region" field. Then I get this: Note that none of the entries include "Ctrl + Shift + PrintScreen" that it's warning about. Now I will change all the hotkeys so I get something like this: So now I'm using QWERTY letters for binding, like Ctrl+Alt+Q, Ctrl+Alt+W and so on. As far as I know no Windows program is using these. While I was clicking through the different fields it was giving me the warning. Now when I try to click OK to save the changes, it once again gives me a warning about "ctrl + shift + printscreen". Update 3 After setting the above key bindings (QWERTY) and saving changes, and then rebooting, the conflict seems to have been resolved. I was then able to set following key bindings. Capture full screen: Prntscrn Capture window: Alt + Prntscrn Capture region: Ctrl + Prntscrn I was not prompted with the warning message this time. Perhaps changing key binding required a system reboot? Sounds far fetched but that appears to be the case. I'm still not sure what caused this conflict, but I know for sure that it started after installing aforementioned programs. It might just have to do with Greenshot itself, and not some other program. Like I said, I know from experience that Greenshot likes to mess with users' settings after each update. I wouldn't be surprised if it was actually silently updated, even though I have specified not to check for updates, then it changed the key bindings back to defaults and caused a conflict with the hotkeys that were registered with the operating system previously. I rarely reboot the system, so that could have added to the conflict. Next time if I see this I will run Hotkey Explorer immediately and see if there is another program causing the conflict.

• How to diagnose computer lockups and freezes?

  - by Scott Mitchell

  I built a desktop computer a couple years back with the following specs: CPU: Intel Core 2 Quad Q9300 Yorkfield 2.5GHz 6 MB L2 Cache LGA 775 95W Quad-Core Processor BX80580Q9300 Motherboard: EVGA 122-CK-NF68-T1 LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard Video Card: Two EVGA 256-P2-N758-TR GeForce 8600GT SCC 256 MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card PSU: SeaSonic S12 Energy Plus SS-550HT 550W ATX12V V2.3 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply Memory: Two G.SKILL 4 GB (2 x 2 GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-4GBPQ Since its inception, the machine has periodically locked up, the regularity having varied over the years from once a day to once a month. Typically, lockups happen once every few days. By "lockup" I mean my computer just freezes. The screen locks up, I can't move the mouse. Hitting keys on my keyboard that normally turn LEDs on or off on the keyboard (such as Caps Lock) no longer turn the LEDs on or off. If there was music playing at the time of the lockup, noise keeps coming out of the speakers, but it's just the current frequency/note that plays indefinitely. There is no BSOD. When such a lockup occurs I have to do a hard reboot by either turning off the computer or hitting the reset button. I have the most recent version of the NVIDIA hardware drivers, and update them semi-regularly, but that hasn't seemed to help. I am currently using Windows 7 x64, but was previously using Windows Server 2003 x64 and having the same lockup issues. My guess is that it's somehow video driver or motherboard related, but I don't know how to go about diagnosing this problem to narrow down which of the two is the culprit. Additional information re: cooling Regarding cooling... I've not installed any after-market cooling systems aside from two regular fans I scavenged from an older computer. The fan atop the CPU is the one that shipped with it. One of the two scavenged fans I added it located at the bottom tower of the corner, in an attempt to create some airflow from front to back. The second fan is pointed directly at the two video cards. SpeedFan installation and readings Per studiohack's suggestion, I installed SpeedFan, which provided the following temperature readings: GPU: 63C GPU: 65C System: 76C CPU: 64C AUX: 36C Core 0: 78C Core 1: 76C Core 2: 79C Core 3: 79C Update #3: Another Lockup :-( Well, I had another lockup last night. :-( SpeedFan reported the CPU temp at 38 C when it happened, and there was no spike in temperature leading up to the freeze. One thing I notice is that the freeze seems more likely to happen if I am watching a video. In fact, of the last 5 freezes over the past month, 4 of them have been while watching a video on Flickr. Not necessarily the same video, but a video nevertheless. I don't know if this is just coincidence or if it means anything. (As an aside, each night before bedtime my 2 year old daughter sits on my lap and watches some home videos on Flickr and, in the last month, has learned the phrase, "Uh oh, computer broke.") Update #4: MemTest86 and 3DMark06 Test Results: Per suggestions in the comments, I ran the MemTest86 overnight and it cycled through the 8 GB of memory 5 times without error. I also ran the 3DMark06 test without a problem (see my scores at http://3dmark.com/3dm06/15163549). So... what now? :-) Any further suggestions on what to check? Is there some way to get a stack trace or something when the computer locks like that? Resolution I have never did figure out the particular problems, but based on the suggestions here and elsewhere, I'm presuming it was a motherboard issue. In any event, I recently upgraded my system, buying a new motherbeard, PSU, CPU, and RAM, and that new rig has been working splendidly the past several weeks. I am using the same graphic cards as in the old setup, so I think it's safe to reason that they weren't the cause of the problem.

• Too many Bind query (cache) denied, DNS attack?

  - by Jake

  Once Bind crashed and I did: tail -f /var/log/messages I see a massive number of logs every second. Is this a DNS attack? or is there something wrong? Sometimes I see a domain in logs like this: dOmAin.com (upper and lower). As you see there is only one single domain in the logs with different IPs Oct 10 02:21:26 mail named[20831]: client 74.125.189.18#38921: query (cache) 'ns1.domain2.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 192.221.144.171#38833: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 74.125.189.17#42428: query (cache) 'ns2.domain2.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 192.221.146.27#37899: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 193.203.82.66#39263: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 8.0.16.170#59723: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 80.169.197.66#32903: query (cache) 'dOmAin.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 134.58.60.1#47558: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 192.221.146.34#47387: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 8.0.16.8#59392: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 74.125.189.19#64395: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 217.72.163.3#42190: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 83.146.21.252#22020: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 192.221.146.116#57342: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 193.203.82.66#52020: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 8.0.16.72#64317: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 80.169.197.66#31989: query (cache) 'dOmAin.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 74.125.189.18#47436: query (cache) 'ns2.domain2.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 74.125.189.16#44005: query (cache) 'ns1.domain2.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 85.132.31.10#50379: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 94.241.128.3#60106: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 85.132.31.10#59118: query (cache) 'domain.com/A/IN' denied Oct 10 02:21:26 mail named[20831]: client 212.95.135.78#27811: query (cache) 'domain.com/A/IN' denied /etc/resolv.conf ; generated by /sbin/dhclient-script nameserver 4.2.2.4 nameserver 8.8.4.4 Bind config: // generated by named-bootconf.pl options { directory "/var/named"; /* * If there is a firewall between you and nameservers you want * to talk to, you might need to uncomment the query-source * directive below.

• Installing XP through USB-flash disc

  - by Crazy Buddy

  I don't know whether this could be asked here... So, Pardon me for this. Probably, this is based on My laptop and a contradiction to this question asked already here... I tried to format my "government-provided" laptop (No CD-drive). I thought those IT guys are proving that they're too smart..! I have the Windows XP CD right now. I didn't like to stick with some home-made OS from our Government. So, I used another laptop to format the govt. thing and tried to install XP (As I didn't have enough bills to invest on Windows 7 or 8). Case 1: First, I allowed WinSetupFromUSB 1.0 beta 8 to deal with the flash disk. I wondered for the first time that XP text-screen appeared. Using the first part, I formatted my laptop. It started to copy files, entered into the next part, and completed the installation. I started my PC for the first time. XP splash screen appeared. Suddenly, a blue screen flashed and disappeared (I can't even read what it says). Rebooted and arrived at the screen, "Start Windows Normally". It happens and happens still - like an infinite loop :-) Case 2: Next, I used Rufus 1.2.0 to transfer files to my Flash and it screwed everything out. Even if I used Flash to boot, it arrives to the same screen "Start Windows normally". It doesn't show any response of Flash being inserted. Then I recognized that, It's simply copies everything to the flash disk. Case 3: Then, I started with Novicorp WinToFlash (giving utmost priority to this site). I booted with the disk. I entered into the first part - "Text mode". Some lines started running like that "Press F6 if you..." like that. The last thing I saw was, "Setup is starting Windows..." Suddenly a blue screen appeared like this captured one. I've a suspicion that the same screen appears again & again in first case. Man, I'm dead. Case 4: For the sake of my last hope, I used WinSetupFromUSB 0.1.1. I was shocked on arriving at a screen which says something "GRUB4DOS" like that and some commands like {command line, reboot, halt, \find menu.lst} and when I go inside those "find" options, I see "Error:15 - File not found". Googling provided some commands to mount SETUPLDR.BIN file in the "grub" thing which also proved unsuccessful... Some sites say that Factory reset uses only some function keys. A guy said that it's F11 for lenovo. Screw him. It's all a waste-of-time. But, I think SE would help me out. Is our government IT guys doin' this to me? Are they Soooo smart to spark some blue screen in front of me to freak me out? Any suggestions or new (useful) USB transferring things would be appreciated. It's very urgent. So, It'd be better if you guys pay some attention in debugging and help me out..? Thanks for your time guys :-)

• amplified reflected attack on dns

  - by Mike Janson

  The term is new to me. So I have a few questions about it. I've heard it mostly happens with DNS servers? How do you protect against it? How do you know if your servers can be used as a victim? This is a configuration issue right? my named conf file include "/etc/rndc.key"; controls { inet 127.0.0.1 allow { localhost; } keys { "rndc-key"; }; }; options { /* make named use port 53 for the source of all queries, to allow * firewalls to block all ports except 53: */ // query-source port 53; /* We no longer enable this by default as the dns posion exploit has forced many providers to open up their firewalls a bit */ // Put files that named is allowed to write in the data/ directory: directory "/var/named"; // the default pid-file "/var/run/named/named.pid"; dump-file "data/cache_dump.db"; statistics-file "data/named_stats.txt"; /* memstatistics-file "data/named_mem_stats.txt"; */ allow-transfer {"none";}; }; logging { /* If you want to enable debugging, eg. using the 'rndc trace' command, * named will try to write the 'named.run' file in the $directory (/var/named"). * By default, SELinux policy does not allow named to modify the /var/named" directory, * so put the default debug log file in data/ : */ channel default_debug { file "data/named.run"; severity dynamic; }; }; view "localhost_resolver" { /* This view sets up named to be a localhost resolver ( caching only nameserver ). * If all you want is a caching-only nameserver, then you need only define this view: */ match-clients { 127.0.0.0/24; }; match-destinations { localhost; }; recursion yes; zone "."

• My PC suddenly doesn't detect the primary drive (SSD)

  - by smoth190

  My computer has been working fine for months, and it worked today, but tonight I went to start it up to find that my OCZ Vertex 2 isn't being found. When I turn on my computer, the loading screen gets stuck at "Detecting IDE drives...". After a while, it keeps going and lists the drives it finds. The first one in the list should be my Vertex 2, but it just says "None". The computer proceeds to get stuck on "Loading operating system...", which is understandable because the drive with the OS is "gone". My first thought was drive failure, but every time drives have crashed on me, they're still detected--they just don't work. This drive is an SSD, it's pretty new, and I had no problems beforehand. I find it hard to believe it failed. I'm sure it's possible, but I hope this isn't the case. There has been nothing strange going on at all with my PC, it's been running perfect until now. I was just about to do my monthly dskchk and defrag today. I popped in my Windows 7 Home Premium disk and booted from it. When I launched the repair tool, it didn't list any operating systems (because the drive is 100% missing...). When I've had disks crash before, it still listed the OS, you just couldn't do anything with it. I tried to restore from an image, but I don't have any of those, either. I opened the command console and listed the drivers with wmic logicaldisk get name. Only C: and D: came up. C: was my 1TB storage driver (luckily, all my stuff is here--only the OS is on the SSD!) and D: was the disk driver. So I still had an MIA drive... The SSD didn't come with any driver disks, so I can't install drivers. If there's a way to do this from a CD I can burn with my other PC, please let me know. What the heck do I do? Although only the OS is on my SSD, a new SSD is expensive. I'll probably also have to buy a new copy of Windows (an upgrade would be nice, though...) because I've found it eats my registration key when my PC crashes (and my thousands of dollars of Adobe programs, I'll be on the phone with tech support for a week to get those keys back). And I'll lose my registry, all my settings, all sorts of other stuff that I'll spend weeks restoring. My computer is a pain in the butt to take out and open up, so if I can't fix it, I'll try fiddling with the plug or putting it into a new computer, but not right now. Any help is greatly appreciated! The day when they make crash-less drives will be the day I live without worry.

• RSA decrypting data in C# (.NET 3.5) which was encrypted with openssl in php 5.3.2

  - by panny

  Maybe someone can clear me up. I have been surfing on this a while now. Step #1: Create a root certificate Key generation on unix 1) openssl req -x509 -nodes -days 3650 -newkey rsa:1024 -keyout privatekey.pem -out mycert.pem 2) openssl rsa -in privatekey.pem -pubout -out publickey.pem 3) openssl pkcs12 -export -out mycertprivatekey.pfx -in mycert.pem -inkey privatekey.pem -name "my certificate" Step #2: Does root certificate work on php: YES PHP side I used the publickey.pem to read it into php: $publicKey = "file://C:/publickey.pem"; $privateKey = "file://C:/privatekey.pem"; $plaintext = "123"; openssl_public_encrypt($plaintext, $encrypted, $publicKey); $transfer = base64_encode($encrypted); openssl_private_decrypt($encrypted, $decrypted, $privateKey); echo $decrypted; // "123" OR $server_public_key = openssl_pkey_get_public(file_get_contents("C:\publickey.pem")); // rsa encrypt openssl_public_encrypt("123", $encrypted, $server_public_key); and the privatekey.pem to check if it works: openssl_private_decrypt($encrypted, $decrypted, openssl_get_privatekey(file_get_contents("C:\privatekey.pem"))); echo $decrypted; // "123" Coming to the conclusion, that encryption/decryption works fine on the php side with these openssl root certificate files. Step #3: Does root certificate work on .NET: YES C# side In same manner I read the keys into a .net C# console program: X509Certificate2 myCert2 = new X509Certificate2(); RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(); try { myCert2 = new X509Certificate2(@"C:\mycertprivatekey.pfx"); rsa = (RSACryptoServiceProvider)myCert2.PrivateKey; } catch (Exception e) { } byte[] test = {Convert.ToByte("123")}; string t = Convert.ToString(rsa.Decrypt(rsa.Encrypt(test, false), false)); Coming to the point, that encryption/decryption works fine on the c# side with these openssl root certificate files. Step #4: Enrypt in php and Decrypt in .NET: !!NO!! PHP side $onett = "123" .... openssl_public_encrypt($onett, $encrypted, $server_public_key); $onettbase64 = base64_encode($encrypted); copy - paste $onettbase64 ("LkU2GOCy4lqwY4vtPI1JcsxgDgS2t05E6kYghuXjrQe7hSsYXETGdlhzEBlp+qhxzTXV3pw+AS5bEg9CPxqHus8fXHOnXYqsd2HL20QSaz+FjZee6Kvva0cGhWkFdWL+ANDSOWRWo/OMhm7JVqU3P/44c3dLA1eu2UsoDI26OMw=") into c# program: C# side byte[] transfered_onettbase64 = Convert.FromBase64String("LkU2GOCy4lqwY4vtPI1JcsxgDgS2t05E6kYghuXjrQe7hSsYXETGdlhzEBlp+qhxzTXV3pw+AS5bEg9CPxqHus8fXHOnXYqsd2HL20QSaz+FjZee6Kvva0cGhWkFdWL+ANDSOWRWo/OMhm7JVqU3P/44c3dLA1eu2UsoDI26OMw="); string k = Convert.ToString(rsa.Decrypt(transfered_onettbase64, false)); // Bad Data exception == Exception while decrypting!!!

• Focusable EditText inside ListView

  - by Joe

  I've spent about 6 hours on this so far, and been hitting nothing but roadblocks. The general premise is that there is some row in a ListView (whether it's generated by the adapter, or added as a header view) that contains an EditText widget and a Button. All I want to do is be able to use the jogball/arrows, to navigate the selector to individual items like normal, but when I get to a particular row -- even if I have to explicitly identify the row -- that has a focusable child, I want that child to take focus instead of indicating the position with the selector. I've tried many possibilities, and have so far had no luck. layout: <ListView android:id="@android:id/list" android:layout_height="fill_parent" android:layout_width="fill_parent" /> Header view: EditText view = new EditText(this); listView.addHeaderView(view, null, true); Assuming there are other items in the adapter, using the arrow keys will move the selection up/down in the list, as expected; but when getting to the header row, it is also displayed with the selector, and no way to focus into the EditText using the jogball. Note: tapping on the EditText will focus it at that point, however that relies on a touchscreen, which should not be a requirement. ListView apparently has two modes in this regard: 1. setItemsCanFocus(true): selector is never displayed, but the EditText can get focus when using the arrows. Focus search algorithm is hard to predict, and no visual feedback (on any rows: having focusable children or not) on which item is selected, both of which can give the user an unexpected experience. 2. setItemsCanFocus(false): selector is always drawn in non-touch-mode, and EditText can never get focus -- even if you tap on it. To make matters worse, calling editTextView.requestFocus() returns true, but in fact does not give the EditText focus. What I'm envisioning is basically a hybrid of 1 & 2, where rather than the list setting if all items are focusable or not, I want to set focusability for a single item in the list, so that the selector seamlessly transitions from selecting the entire row for non-focusable items, and traversing the focus tree for items that contain focusable children. Any takers?

• How can I load style resources from a dynamically loaded Silverlight application (XAP)?

  - by Tom

  I've followed Tim Heuer's video for dynamically loading other XAP's (into a 'master' Silverlight application), as well as some other links to tweak the loading of resources and am stuck on the particular issue of loading style resources from within the dynamically loaded XAP (i.e. the contents of Assets\Styles.xaml). When I run the master/hosting applcation, it successfully streams the dynamic XAP and I can read the deployment info etc. and load the assembly parts. However, when I actuall try to create an instance of a form from the Dynamic XAP, it fails with Cannot find a Resource with the Name/Key LayoutRootGridStyle which is in it's Assets\Styles.xaml file (it works if I run it directly so I know it's OK). For some reason these don't show up as application resources - not sure if I've totally got the wrong end of the stick, or am just missing something? Code snippet below (apologies it's a bit messy - just trying to get it working first) ... '' # Here's the code that reads the dynamic XAP from the web server ... '' #... wCli = New WebClient AddHandler wCli.OpenReadCompleted, AddressOf OpenXAPCompleted wCli.OpenReadAsync(New Uri("MyTest.xap", UriKind.Relative)) '' #... '' #Here's the sub that's called when openread is completed '' #... Private Sub OpenXAPCompleted(ByVal sender As Object, ByVal e As System.Net.OpenReadCompletedEventArgs) Dim sManifest As String = New StreamReader(Application.GetResourceStream(New StreamResourceInfo(e.Result, Nothing), New Uri("AppManifest.xaml", UriKind.Relative)).Stream).ReadToEnd Dim deploymentRoot As XElement = XDocument.Parse(sManifest).Root Dim deploymentParts As List(Of XElement) = _ (From assemblyParts In deploymentRoot.Elements().Elements() Select assemblyParts).ToList() Dim oAssembly As Assembly = Nothing For Each xElement As XElement In deploymentParts Dim asmPart As AssemblyPart = New AssemblyPart() Dim source As String = xElement.Attribute("Source").Value Dim sInfo As StreamResourceInfo = Application.GetResourceStream(New StreamResourceInfo(e.Result, "application/binary"), New Uri(source, UriKind.Relative)) If source = "MyTest.dll" Then oAssembly = asmPart.Load(sInfo.Stream) Else asmPart.Load(sInfo.Stream) End If Next Dim t As Type() = oAssembly.GetTypes() Dim AppClass = (From parts In t Where parts.FullName.EndsWith(".App") Select parts).SingleOrDefault() Dim mykeys As Array If Not AppClass Is Nothing Then Dim a As Application = DirectCast(oAssembly.CreateInstance(AppClass.FullName), Application) For Each strKey As String In a.Resources.Keys If Not Application.Current.Resources.Contains(strKey) Then Application.Current.Resources.Add(strKey, a.Resources(strKey)) End If Next End If Dim objectType As Type = oAssembly.GetType("MyTest.MainPage") Dim ouiel = Activator.CreateInstance(objectType) Dim myData As UIElement = DirectCast(ouiel, UIElement) Me.splMain.Children.Add(myData) Me.splMain.UpdateLayout() End Sub '' #... '' # And here's the line that fails with "Cannot find a Resource with the Name/Key LayoutRootGridStyle" '' # ... System.Windows.Application.LoadComponent(Me, New System.Uri("/MyTest;component/MainPage.xaml", System.UriKind.Relative)) '' #... any thoughts?

• Entity Framework won't SaveChanges on new entity with two-level relationship

  - by Tim Rourke

  I'm building an ASP.NET MVC site using the ADO.NET Entity Framework. I have an entity model that includes these entities, associated by foreign keys: Report(ID, Date, Heading, Report_Type_ID, etc.) SubReport(ID, ReportText, etc.) - one-to-one relationship with Report. ReportSource(ID, Name, Description) - one-to-many relationship with Sub_Report. ReportSourceType(ID, Name, Description) - one-to-many relationship with ReportSource. Contact (ID, Name, Address, etc.) - one-to-one relationship with Report_Source. There is a Create.aspx page for each type of SubReport. The post event method returns a new Sub_Report entity. Before, in my post method, I followed this process: Set the properties for a new Report entity from the page's fields. Set the SubReport entity's specific properties from the page's fields. Set the SubReport entity's Report to the new Report entity created in 1. Given an ID provided by the page, look up the ReportSource and set the Sub_Report entity's ReportSource to the found entity. SaveChanges. This workflow succeeded just fine for a couple of weeks. Then last week something changed and it doesn't work any more. Now instead of the save operation, I get this Exception: UpdateException: "Entities in 'DIR2_5Entities.ReportSourceSet' participate in the 'FK_ReportSources_ReportSourceTypes' relationship. 0 related 'ReportSourceTypes' were found. 1 'Report_Source_Types' is expected." The debug visualizer shows the following: The SubReport's ReportSource is set and loaded, and all of its properties are correct. The Report_Source has a valid ReportSourceType entity attached. In SQL Profiler the prepared SQL statement looks OK. Can anybody point me to what obvious thing I'm missing? TIA Notes: The Report and SubReport are always new entities in this case. The Report entity contains properties common to many types of reports and is used for generic queries. SubReports are specific reports with extra parameters varying by type. There is actually a different entity set for each type of SubReport, but this question applies to all of them, so I use SubReport as a simplified example.

• Using 32bit COM object from C# or VBS on Vista 64bit and getting error 80004005

  - by alexandroid

  I need some mind reading here, since I am trying to do what I do not completely understand. There is a 32-bit application (electronic trading application called CQG) which provides a COM API for external access. I have sample programs and scripts which access this API from Excel, .NET (C++, VB and C#) and shell VBScript. I have these .NET applications as source code and as compiled executables (32-bit, compiled on Windows XP). Now I have Windows Vista Home 64-bit which makes my head to spin. Excel examples work just fine (in Excel 2003). Compiled .NET sample executables work as well. But when I am trying to run .NET C# sample converted to and compiled by Visual Studio C# Expression, or run the VBScript script, I am getting error 80004005 when trying to create an object. Initially the .NET application also gave me 80040154 but then I figured how to make it produce 32-bit code and not 64-bit, so now the errors in C# and VBScript applications are the same. That's all the progress I got for now. And yes, I tried running 32-bit versions of cscript.exe/WScript from SysWOW64 folder on my VBS, but still the result is the same (80004005). How to solve this problem? I am almost ready to believe it is practically impossible, but the fact that Excel VBA works and .NET executables compiled on Windows XP run just fine just makes me angry. There should be a way to beat this thing (some secret which probably only Windows Vista developers know)! I will appreciate any help! PS: I believe code samples do not make much sense here, but this is the line of VBScript which fails: Set CEL = WScript.CreateObject("CQG.CQGCEL.4.0", "CEL_") And this is C#: CQGCEL CEL = new CQGCEL(); Update: Forgot to say UAC is off, of course. And I am working from account with administrator priviledges. I also tried watching which registry keys are read using Process Monitor but everything looks OK for GUIDs of this object. I could not recognize some other GUIDs so I am not sure whether they were critical or not. Is there a chance that this COM object uses Internet Explorer and gets the wrong one (like Internet Explorer 7 instead of Internet Explorer 6 engine or something)?

• Asp.NET MVC ActionFilter cannot get Form Submit data

  - by Goden

  I want to use custom action filter to manipulate parameters to one action. User inputs: 2 names in a form ; Action: actually needs to take 2 ids; Action Filter (onExecuting, will verify the input names and if valid, convert them into 2 ids and replace in the routedata) because i don't want to put validation logic in Action Controller. here's part of the code: Routing Info routes.MapRoute( "Default", // Route name "{controller}/{action}", // URL with parameters new { controller = "Home", action = "Index"} // Parameter defaults ); routes.MapRoute( "RelationshipResults", // Route Name "Relationship/{initPersonID}/{targetPersonID}", // URL with parameters new { controller = "Relationship", action = "Results" }); Form to submit (Create 2 input box and submit via jquery) <% using (Html.BeginForm("Results", "Relationship", FormMethod.Post, new { id = "formSearch" })) {% ... <td align="left"><%: MvcWeibookWeb.Properties.Resource.Home_InitPersonName%></td> <td align="right"> <%= Html.TextBox("initPersonName")%></td> <td rowspan="3" valign="top"> <div id="sinaIntro"> <%: MvcWeibookWeb.Properties.Resource.Home_SinaIntro %> <br /> <%: MvcWeibookWeb.Properties.Resource.Genearl_PromotionSina %> </div> </td> </tr> <tr> <td align="left" width="90px"><%: MvcWeibookWeb.Properties.Resource.Home_TargetPersonName%></td> <td align="right"><%= Html.TextBox("targetPersonName")%></td> </tr> <tr> <td colspan="2" align="right"> <a href="#" class="btn-HomeSearch" onclick="$('#formSearch').submit();"><%: MvcWeibookWeb.Properties.Resource.Home_Search%></a> </td> Action Filter public override void OnActionExecuting(ActionExecutingContext filterContext) { Sina.Searcher searcher = new Sina.Searcher(Sina.Processor.UserNetwork); String initPersonName, targetPersonName; // form submit names, we need to process them and convert them to IDs before it enters the real controller. initPersonName = filterContext.RouteData.Values["initPersonName"] as String; targetPersonName = filterContext.RouteData.Values["targetPersonName"] as String; // do sth to convert it to ids and replace Action/Controller [ValidationActionFilter] [HandleError] public ActionResult Results( Int64 initPersonName, Int64 targetPersonName) { ... My problem is: in the actionFilter, it never gets the 2 parameter "initPersonName" and "targetPersonName", the RouteData.Values don't contain these 2 keys... :(

• CherryPy sessions for same domain, different port

  - by detly

  Consider the script below. It will launch two subprocesses, each one a CherryPy app (hit Ctrl+C or whatever the KeyboardInterrupt combo is on your system to end them both). If you run it with CP 3.0 (taking care to change the 3.0/3.1 specific lines in "StartServer"), then visit: http://localhost:15002/ ...you see an empty dict. Then visit: http://localhost:15002/set?val=10 http://localhost:15002/ ...and you see the newly populated dict. Then visit: http://localhost:15012/ ...and go back to http://localhost:15002/ ...and nothing has changed. If you try the same thing with CP 3.1 (remember the lines in "StartServer"!), when you get to the last step, the dict is now empty. This happens in Windows and Debian, Python 2.5 and 2.6. You can try all sorts of things: changing to file storage, separating the storage paths... the only difference it makes is that the sessions might get merged instead of erased. I've read another post about this as well, and there's a suggestion there to put the session tools config keys in the app config rather than the global config, but I don't think that's relevant to this usage where the apps run independently. What do I do to get independent CherryPy applications to NOT interfere with each other? Note: I originally asked this on the CherryPy mailing list but haven't had a response yet so I'm trying here. I hope that's okay. import os, os.path, socket, sys import subprocess import cgi import cherrypy HTTP_PORT = 15002 HTTP_HOST = "127.0.0.1" site1conf = { 'global' : { 'server.socket_host' : HTTP_HOST, 'server.socket_port' : HTTP_PORT, 'tools.sessions.on' : True, # 'tools.sessions.storage_type': 'file', # 'tools.sessions.storage_path': '1', # 'tools.sessions.storage_path': '.', 'tools.sessions.timeout' : 1440}} site2conf = { 'global' : { 'server.socket_host' : HTTP_HOST, 'server.socket_port' : HTTP_PORT + 10, 'tools.sessions.on' : True, # 'tools.sessions.storage_type': 'file', # 'tools.sessions.storage_path': '2', # 'tools.sessions.storage_path': '.', 'tools.sessions.timeout' : 1440}} class Home(object) : def __init__(self, key): self.key = key @cherrypy.expose def index(self): return """\ <html> <body>Session: <br>%s </body> </html> """ % cgi.escape(str(dict(cherrypy.session))) @cherrypy.expose def set(self, val): cherrypy.session[self.key.upper()] = val return """\ <html> <body>Set %s to %s</body> </html>""" % (cgi.escape(self.key), cgi.escape(val)) def StartServer(conf, key): cherrypy.config.update(conf) print 'Starting server (%s)' % key cherrypy.tree.mount(Home(key), '/', {}) # Start the web server. #### 3.0 # cherrypy.server.quickstart() # cherrypy.engine.start() #### #### 3.1 cherrypy.engine.start() cherrypy.engine.block() #### def Main(): # Start first webserver proc1 = subprocess.Popen( [sys.executable, os.path.abspath(__file__), "1"]) proc2 = subprocess.Popen( [sys.executable, os.path.abspath(__file__), "2"]) proc1.wait() proc2.wait() if __name__ == "__main__": print sys.argv if len(sys.argv) == 1: # Master process Main() elif(int(sys.argv[1]) == 1): StartServer(site1conf, 'magic') elif(int(sys.argv[1]) == 2): StartServer(site2conf, 'science') else: sys.exit(1)

• XNA - Keyboard text input

  - by Sekhat

  Okay, so basically I want to be able to retrieve keyboard text. Like entering text into a text field or something. I'm only writing my game for windows. I've disregarded using Guide.BeginShowKeyboardInput because it breaks the feel of a self contained game, and the fact that the Guide always shows XBOX buttons doesn't seem right to me either. Yes it's the easiest way, but I don't like it. Next I tried using System.Windows.Forms.NativeWindow. I created a class that inherited from it, and passed it the Games window handle, implemented the WndProc function to catch WM_CHAR (or WM_KEYDOWN) though the WndProc got called for other messages, WM_CHAR and WM_KEYDOWN never did. So I had to abandon that idea, and besides, I was also referencing the whole of Windows forms, which meant unnecessary memory footprint bloat. So my last idea was to create a Thread level, low level keyboard hook. This has been the most successful so far. I get WM_KEYDOWN message, (not tried WM_CHAR yet) translate the virtual keycode with Win32 funcation MapVirtualKey to a char. And I get my text! (I'm just printing with Debug.Write at the moment) A couple problems though. It's as if I have caps lock on, and an unresponsive shift key. (Of course it's not however, it's just that there is only one Virtual Key Code per key, so translating it only has one output) and it adds overhead as it attaches itself to the Windows Hook List and isn't as fast as I'd like it to be, but the slowness could be more due to Debug.Write. Has anyone else approached this and solved it, without having to resort to an on screen keyboard? or does anyone have further ideas for me to try? thanks in advance. note: This is cross posted from the XNA Creators Forums, so if I get an answer there I'll post it here and Vice-Versa Question asked by Jimmy Maybe I'm not understanding the question, but why can't you use the XNA Keyboard and KeyboardState classes? My comment: It's because though you can read keystates, you can't get access to typed text as and how it is typed by the user. So let me further clarify. I want to implement being able to read text input from the user as if they are typing into textbox is windows. The keyboard and KeyboardState class get states of all keys, but I'd have to map each key and combination to it's character representation. This falls over when the user doesn't use the same keyboard language as I do especially with symbols (my double quotes is shift + 2, while american keyboards have theirs somewhere near the return key).

• Error using httlib's HTTPSConnection with PKCS#12 certificate

  - by Remi Despres-Smyth

  Hello. I'm trying to use httplib's HTTPSConnection for client validation, using a PKCS #12 certificate. I know the certificate is good, as I can connect to the server using it in MSIE and Firefox. Here's my connect function (the certificate includes the private key). I've pared it down to just the basics: def connect(self, cert_file, host, usrname, passwd): self.cert_file = cert_file self.host = host self.conn = httplib.HTTPSConnection(host=self.host, port=self.port, key_file=cert_file, cert_file=cert_file) self.conn.putrequest('GET', 'pathnet/,DanaInfo=200.222.1.1+') self.conn.endheaders() retCreateCon = self.conn.getresponse() if is_verbose: print "Create HTTPS connection, " + retCreateCon.read() (Note: No comments on the hard-coded path, please - I'm trying to get this to work first; I'll make it pretty afterwards. The hard-coded path is correct, as I connect to it in MSIE and Firefox. I changed the IP address for the post.) When I try to run this using a PKCS#12 certificate (a .pfx file), I get back what appears to be an openSSL error. Here is the entire error traceback: File "Usinghttplib_Test.py", line 175, in t.connect(cert_file=opts["-keys"], host=host_name, usrname=opts["-username"], passwd=opts["-password"]) File "Usinghttplib_Test.py", line 40, in connect self.conn.endheaders() File "c:\python26\lib\httplib.py", line 904, in endheaders self._send_output() File "c:\python26\lib\httplib.py", line 776, in _send_output self.send(msg) File "c:\python26\lib\httplib.py", line 735, in send self.connect() File "c:\python26\lib\httplib.py", line 1112, in connect self.sock = ssl.wrap_socket(sock, self.key_file, self.cert_file) File "c:\python26\lib\ssl.py", line 350, in wrap_socket suppress_ragged_eofs=suppress_ragged_eofs) File "c:\python26\lib\ssl.py", line 113, in __init__ cert_reqs, ssl_version, ca_certs) ssl.SSLError: [Errno 336265225] _ssl.c:337: error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:PEM lib Notice, the openSSL error (the last entry in the list) notes "PEM lib", which I found odd, since I'm not trying to use a PEM certificate. For kicks, I converted the PKCS#12 cert to a PEM cert, and ran the same code using that. In that case, I received no error, I was prompted to enter the PEM pass phrase, and the code did attempt to reach the server. (I received the response "The service is not available. Please try again later.", but I believe that would be because the server does not accept the PEM cert. I can't connect in Firefox to the server using the PEM cert either.) Is httplib's HTTPSConnection supposed to support PCKS#12 certificates? (That is, pfx files.) If so, why does it look like openSSL is trying to load it inside the PEM lib? Am I doing this all wrong? Any advice is welcome. EDIT: The certificate file contains both the certificate and the private key, which is why I'm providing the same file name for both the HTTPSConnection's key_file and cert_file parameters.

• Client-side policy error using JacORB (Java/CORBA) with SSL

  - by jason

  I'm trying to add SSL to an existing CORBA app, and I keep getting this error: org.omg.CORBA.NO_PERMISSION: Client-side policy requires SSL/TLS, but server doesn't support it vmcid: 0x0 minor code: 0 completed: No at org.jacorb.orb.iiop.ClientIIOPConnection.checkSSL(ClientIIOPConnection.java:535) at org.jacorb.orb.iiop.ClientIIOPConnection.connect(ClientIIOPConnection.java:144) at org.jacorb.orb.giop.GIOPConnection.sendMessage(GIOPConnection.java:835) at org.jacorb.orb.giop.GIOPConnection.sendRequest(GIOPConnection.java:805) at org.jacorb.orb.giop.ClientConnection.sendRequest(ClientConnection.java:302) at org.jacorb.orb.giop.ClientConnection.sendRequest(ClientConnection.java:282) at org.jacorb.orb.Delegate.invoke_internal(Delegate.java:919) at org.jacorb.orb.Delegate.invoke(Delegate.java:868) at org.jacorb.orb.Delegate.is_a(Delegate.java:1268) at org.omg.CORBA.portable.ObjectImpl._is_a(ObjectImpl.java:112) at databridge.autogen.ILoginManagerHelper.narrow(ILoginManagerHelper.java:57) at databridge.test.Client.main(Client.java:59) I have generated keystores for both client and server and exchanged the keys between the two. Using this setup, I can get the demo application that came in the JacORB download to run successfully. The only difference I can tell is that my test is using the Tie method to get the POA. There are some policies that go into that, but I can't find any information on what policies need to go in there to enable SSL, if any. I'm not even sure that's the problem as the JacORB demo doesn't set any policies on the server or poa. When I run the -Djavax.net.debug=ssl, I can see the keystores load up the trusted certs on both the client and the server. I'm just not sure what policies are being referred to here, but it's odd that the demo works and the test doesn't using the exact same keystores and properties. I've emailed the mailing list, but I'm not holding out much hope as that doesn't seem to be very active. Any help would be greatly appreciated. Below are my properties files.

• DataTable identity column not set after DataAdapter.Update/Refresh on table with "instead of"-trigge

  Within our unit tests we use plain ADO.NET (DataTable, DataAdapter) for preparing the database resp. checking the results, while the tested components themselves run under NHibernate 2.1. .NET version is 3.5, SqlServer version is 2005. The database tables have identity columns as primary keys. Some tables apply instead-of-insert/update triggers (this is due to backward compatibility, nothing I can change). The triggers generally work like this: create trigger dbo.emp_insert on dbo.emp instead of insert as begin set nocount on insert into emp ... select @@identity end The insert statement issued by the ADO.NET DataAdapter (generated on-the-fly by a thin ADO.NET wrapper) tries to retrieve the identity value back into the DataRow: exec sp_executesql N' insert into emp (...) values (...); select id, ... from emp where id = @@identity ' But the DataRow's id-Column is still 0. When I remove the trigger temporarily, it works fine - the id-Column then holds the identity value set by the database. NHibernate on the other hand uses this kind of insert statement: exec sp_executesql N' insert into emp (...) values (...); select scope_identity() ' This works, the NHibernate POCO has its id property correctly set right after flushing. Which seems a little bit counter-intuitive to me, as I expected the trigger to run in a different scope, hence @@identity should be a better fit than scope_identity(). So I thought no problem, I will apply scope_identity() instead of @@identity under ADO.NET as well. But this has no effect, the DataRow value is still not updated accordingly. And now for the best part: When I copy and paste those two statements from SqlServer profiler into a Management Studio query (that is including "exec sp_executesql"), and run them there, the results seem to be inverse! There the ADO.NET version works, and the NHibernate version doesn't (select scope_identity() returns null). I tried several times to verify, but to no avail. Of course this just shows the resultset coming from the database, whatever happens inside NHibernate and ADO.NET is another topic. Also, several session properties defined by T-SQL SET are different in the two scenarios (Management Studio query vs. application at runtime) This is a real puzzle to me. I would be happy about any insights on that. Thank you!

• How to change Matlab program for solving equation with finite element method?

  - by DSblizzard

  I don't know is this question more related to mathematics or programming and I'm absolute newbie in Matlab. Program FEM_50 applies the finite element method to Laplace's equation -Uxx(x, y) - Uyy(x, y) = F(x, y) in Omega. How to change it to apply FEM to equation -Uxx(x, y) - Uyy(x, y) + U(x, y) = F(x, y)? At this page: http://sc.fsu.edu/~burkardt/m_src/fem_50/fem_50.html additional code files in case you need them. function fem_50 ( ) %% FEM_50 applies the finite element method to Laplace's equation. % % Discussion: % % FEM_50 is a set of MATLAB routines to apply the finite % element method to solving Laplace's equation in an arbitrary % region, using about 50 lines of MATLAB code. % % FEM_50 is partly a demonstration, to show how little it % takes to implement the finite element method (at least using % every possible MATLAB shortcut.) The user supplies datafiles % that specify the geometry of the region and its arrangement % into triangular and quadrilateral elements, and the location % and type of the boundary conditions, which can be any mixture % of Neumann and Dirichlet. % % The unknown state variable U(x,y) is assumed to satisfy % Laplace's equation: % -Uxx(x,y) - Uyy(x,y) = F(x,y) in Omega % with Dirichlet boundary conditions % U(x,y) = U_D(x,y) on Gamma_D % and Neumann boundary conditions on the outward normal derivative: % Un(x,y) = G(x,y) on Gamma_N % If Gamma designates the boundary of the region Omega, % then we presume that % Gamma = Gamma_D + Gamma_N % but the user is free to determine which boundary conditions to % apply. Note, however, that the problem will generally be singular % unless at least one Dirichlet boundary condition is specified. % % The code uses piecewise linear basis functions for triangular elements, % and piecewise isoparametric bilinear basis functions for quadrilateral % elements. % % The user is required to supply a number of data files and MATLAB % functions that specify the location of nodes, the grouping of nodes % into elements, the location and value of boundary conditions, and % the right hand side function in Laplace's equation. Note that the % fact that the geometry is completely up to the user means that % just about any two dimensional region can be handled, with arbitrary % shape, including holes and islands. % clear % % Read the nodal coordinate data file. % load coordinates.dat; % % Read the triangular element data file. % load elements3.dat; % % Read the quadrilateral element data file. % load elements4.dat; % % Read the Neumann boundary condition data file. % I THINK the purpose of the EVAL command is to create an empty NEUMANN array % if no Neumann file is found. % eval ( 'load neumann.dat;', 'neumann=[];' ); % % Read the Dirichlet boundary condition data file. % load dirichlet.dat; A = sparse ( size(coordinates,1), size(coordinates,1) ); b = sparse ( size(coordinates,1), 1 ); % % Assembly. % for j = 1 : size(elements3,1) A(elements3(j,:),elements3(j,:)) = A(elements3(j,:),elements3(j,:)) ... + stima3(coordinates(elements3(j,:),:)); end for j = 1 : size(elements4,1) A(elements4(j,:),elements4(j,:)) = A(elements4(j,:),elements4(j,:)) ... + stima4(coordinates(elements4(j,:),:)); end % % Volume Forces. % for j = 1 : size(elements3,1) b(elements3(j,:)) = b(elements3(j,:)) ... + det( [1,1,1; coordinates(elements3(j,:),:)'] ) * ... f(sum(coordinates(elements3(j,:),:))/3)/6; end for j = 1 : size(elements4,1) b(elements4(j,:)) = b(elements4(j,:)) ... + det([1,1,1; coordinates(elements4(j,1:3),:)'] ) * ... f(sum(coordinates(elements4(j,:),:))/4)/4; end % % Neumann conditions. % if ( ~isempty(neumann) ) for j = 1 : size(neumann,1) b(neumann(j,:)) = b(neumann(j,:)) + ... norm(coordinates(neumann(j,1),:) - coordinates(neumann(j,2),:)) * ... g(sum(coordinates(neumann(j,:),:))/2)/2; end end % % Determine which nodes are associated with Dirichlet conditions. % Assign the corresponding entries of U, and adjust the right hand side. % u = sparse ( size(coordinates,1), 1 ); BoundNodes = unique ( dirichlet ); u(BoundNodes) = u_d ( coordinates(BoundNodes,:) ); b = b - A * u; % % Compute the solution by solving A * U = B for the remaining unknown values of U. % FreeNodes = setdiff ( 1:size(coordinates,1), BoundNodes ); u(FreeNodes) = A(FreeNodes,FreeNodes) \ b(FreeNodes); % % Graphic representation. % show ( elements3, elements4, coordinates, full ( u ) ); return end
