  • Drag and Drop from another application with mouse button down does not fire event

    - by Keith
    I am trying to drag and drop a file onto a control in my application. The problem is that when you hold the mouse button down (i.e. dragging from widows explorer), my app does not fire any of the form events. They all work fine if the mouse is not down. Is appears that I need to enable the 'AllowDrop' for the application (it is enabled on the form) What am I missing? I am developing in vb.net 2008 in windows 7 environment

  • cflock do not throw timeout for same url called in same browser

    - by Pritesh Patel
    I am trying lock block on page test.cfm and below is code written on page. <cfscript> writeOutput("Before lock at #now()#"); lock name="threadlock" timeout="3" type="exclusive" { writeOutput("<br/>started at #now()#"); thread action="sleep" duration="10000"; writeOutput("<br/>ended at #now()#"); } writeOutput("<br/>After lock at #now()#"); </cfscript> assuming my url for page is http://localhost.local/test.cfm and running it on browser in two different tabs. I was expecting one of the url will throw timeout error after 3 second since another url lock it atleast for 10 seconds due to thread sleep. Surprisingly I do not get any timeout error rather second page call run after 10 seconds as first call finish execution. But I am appending some url parameter (e.g. http://localhost.local/test.cfm?q=1) will throw error. Also I am calling same url in different browser then one of the call will throw timeout issue. Is lock based on session and url? Update Here is output for two different cases: Case 1: TAB1 Url: http://localhost.local/test/test.cfm Before lock at {ts '2013-10-18 09:21:35'} started at {ts '2013-10-18 09:21:35'} ended at {ts '2013-10-18 09:21:45'} After lock at {ts '2013-10-18 09:21:45'} TAB2 Url: http://localhost.local/test/test.cfm Before lock at {ts '2013-10-18 09:21:45'} started at {ts '2013-10-18 09:21:45'} ended at {ts '2013-10-18 09:21:55'} After lock at {ts '2013-10-18 09:21:55'} Case 2: TAB1 Url: http://localhost.local/test/test.cfm Before lock at {ts '2013-10-18 09:27:18'} started at {ts '2013-10-18 09:27:18'} ended at {ts '2013-10-18 09:27:28'} After lock at {ts '2013-10-18 09:27:28'} TAB2 Url: http://localhost.local/test/test.cfm? (Added ? at the end) Before lock at {ts '2013-10-18 09:27:20'} A timeout occurred while attempting to lock threadlock. The error occurred in C:/inetpub/wwwroot/test/test.cfm: line 13 11 : 12 : <cfoutput>Before lock at #now()#</cfoutput> 13 : <cflock name="threadlock" timeout="3" type="exclusive"> 14 : <cfoutput><br/>started at #now()#</cfoutput> 15 : <cfthread action="sleep" duration="10000"/> ... Result for case 2 as expected. For case 1, strange thing I just noticed is tab 2 output "Before lock at {ts '2013-10-18 09:21:45'} indicates that whole request start after 10 seconds (means after the complete execution of first tab) when I have fired it in second URL just after 2 seconds of first tabs.

  • Drop down view in cocoa

    - by coffeebean
    I'm looking to create a 'drop down' view that falls in front of the main window. An example of this would be the window that drops down when you click 'Advanced' in System Preferences-Networking. If someone could point me in the right direction documentation-wise that would be great. Thanks in advance.

  • Listing the content of a tar file or a directory only down to some level

    - by Tim
    I wonder how to list the content of a tar file only down to some level? I understand tar tvf mytar.tar will list all files, but sometimes I would like to only see directories down to some level. Similarly, for the command ls, how do I control the level of subdirectories that will be displayed? By default, it will only show the direct subdirectories, but not go further.

Similarly for command "ls" how to control the level of subdirectories that will be displayed? By default, it will only show the direct subdirectories, but not further. Thanks and regards

  • Why my reputation goes down.

    - by Incognito
    I know there was a recalculation and I know how to track the reputation, but seems it not helps. My reputation was about 495 just several hours ago and now it goes down to 295. I have checked there were no down votes. What can be the issue?

  • Embedding script with timeout in case server goes down

    - by vsync
    I need a way to make sure my script won't block the viewed page, if the server serving the script is down (port 80 is blocked for some reason). Currently when I test it and take down the server (Apache), or close the firewall, I see in the browser that it is trying to load the resource (script in that case), without success for long seconds, until it aborts. Is there a nice way to get past this issue?

  • Computer Locked after period of time

    - by bossDub
    I have a Windows XP machine that locks itself after an unknown amount of time. I have disabled the screen saver completely, and unchecked "lock computer when coming out of standby". I've even overrode the settings with gpedit. Even still, it locks itself after a while, and it doesn't take long. If it's any sort of hint, the time period for the screensaver is greyed out, even if I choose an actual screensaver.

  • Computer wakes up from hibernation at exctly 3:40am every day

    - by vascoFG
    I'm getting tired of waking up to my computer being turned on, and event log shows that it's waking up everyday at 3:40am and most times won't go back to sleep after the determined 30 minutes (maybe from being in the lock screen?). There are no devices armed for wake, activation timers are disabled and all wake options disabled in the BIOS and energy star 4.0c is enabled (was disabled before but no difference).

  • How to make computer interface with circuit

    - by light.hammer
    I understand that I can build a circuit that will do whatever I like (ex: a simple circuit that will turn on a motor to open the blinds or something), and I can write a program that will automate my computer/mac however I like (ex: open this program at this time, or with this input and create a new file, ect). My question is, how can I interface the two? Is there an easy DIY or cheap commercial (or not cheap but functional) USB plug that will turn on/off from computer commands? I'm basically looking for some sort of on/off switch I can script/applescript. How would you even approach this problem, would I have to write my own driver some where along the way?

  • Remote Desktop, Host: 2008, Client: Windows 7, The remote computer requires Network Level Authentica

    - by deerchao
    Hi, today I accidently changed one option of Teminal Services, I checked "Allow connections only from computers running Remote Desktop with Network Level Authentication". After that, I can't connect to my server any more. The error says: The remote computer requires Network Level Authentication, which your computer does not support. But my client pcs(both home and at office) are running Windows 7, as far as I know, it shoud support NLA; And in About dialog of Remote Desktop Connection there says "Supports Network Level Authentication". My server is running Windows Server 2008, placed in IDC center; I could connect to it before I change the settings. All other sevices(like IIS, SQL Server) are running normally. For clients, I tried two PCs running Windows 7, and two virtual windows XP machine running in Virtual PC and Virtual Box, all of them gives the same error message. Is there a way I can make things right without go to IDC which is far away? Thanks.

  • Clean up infected computer from viruses

    - by ripper234
    I have a computer which had AVG Free installed from day one. After several months of operation, it starts detecting viruses and trojans all the time. Besides running a full scan, what should I do to clean the computer? Should I install another anti-virus or anti-malware tool (can it help?), or once viruses infect a system the only real solution is a clean format? (Lately I've heard of viruses that burn themselves in the BIOS, so a clean format might not always work ... how common is this technique? Should I burn a fresh BIOS as well?)

  • RAMDiskVE keeps causing computer to freeze

    - by Steph
    I found this in the Event Viewer logs: The description for Event ID 11 from source RAMDiskVE cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. Which doesn't say much. The details don't reveal much more: Failed to read configuration information from registry. 0000000002002C00000000000B0007C0000000000000000000000000000000000000000000000000 So my question is, what is RAMDiskVE and what device is it for? Basically I'm trying to rule out hardware but I have no idea what's failing...

  • Computer and internet use on a boat?

    - by dlamblin
    Let's assume that I seriously would like to be able to use my computer as easily and as carefreely while on a boat as I do while at home. In short, if I were on a boat for extended periods, such as two weeks at a time and occasionally over a few days out of port (this would be a 2 person sailing vessel), what would my options be for power, durability, and of course, internet access? I want more than just email, as I will likely keep doing a tad of development, and will be looking at google earth from time to time. I am already assuming that we're going with some kind of laptop, maybe even a macbook pro 12". I personally feel that netbooks are underpowered. And the last computer that I got a boat-friendly rating for was a ZX Spectrum, which was before the internet, and was likely due to it's 12vdc-happiness.

  • Sudden restart now chrome kills computer

    - by Kai
    My computer suddenly restart itself the other day and when it came back up so much as clicking on the icon for Google Chrome freezes everything. I uninstalled Chrome and tried reinstalling is but as soon as the download finished, the computer froze again. I tried installing an earlier version (about a week prior) and it froze differently but still froze. I am also getting notification that the battery needs to be replaced. At the moment I am running it sans battery and using firefox and everything seems to be fine. I have a HP dv4t running Windows 7.

  • NFS issue brings down entire vSphere ESX estate

    - by growse
    I experienced an odd issue this morning where an NFS issue appeared to have taken down the majority of my VMs hosted on a small vSphere 5.0 estate. The infrastructure itself is 4x IBM HS21 blades running around 20 VMs. The storage is provided by a single HP X1600 array with attached D2700 chassis running Solaris 11. There's a couple of storage pools on this which are exposed over NFS for the storage of the VM files, and some iSCSI LUNs for things like MSCS shared disks. Normally, this is pretty stable, but I appreciate the lack of resiliancy in having a single X1600 doing all the storage. This morning, in the logs of each ESX host, at around 0521 GMT I saw a lot of entries like this: 2011-11-30T05:21:54.161Z cpu2:2050)NFSLock: 608: Stop accessing fd 0x41000a4cf9a8 3 2011-11-30T05:21:54.161Z cpu2:2050)NFSLock: 608: Stop accessing fd 0x41000a4dc9e8 3 2011-11-30T05:21:54.161Z cpu2:2050)NFSLock: 608: Stop accessing fd 0x41000a4d3fa8 3 2011-11-30T05:21:54.161Z cpu2:2050)NFSLock: 608: Stop accessing fd 0x41000a4de0a8 3 [....] 2011-11-30T06:16:07.042Z cpu0:2058)WARNING: NFS: 283: Lost connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:17:01.459Z cpu2:4011)NFS: 292: Restored connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:25:17.887Z cpu3:2051)NFSLock: 608: Stop accessing fd 0x41000a4c2b28 3 2011-11-30T06:27:16.063Z cpu3:4011)NFSLock: 568: Start accessing fd 0x41000a4d8928 again 2011-11-30T06:35:30.827Z cpu1:2058)WARNING: NFS: 283: Lost connection to the server 10.13.111.197 mount point /tank/ISO, mounted as 5acdbb3e-410e56e3-0000-000000000000 ("ISO (1)") 2011-11-30T06:36:37.953Z cpu6:2054)NFS: 292: Restored connection to the server 10.13.111.197 mount point /tank/ISO, mounted as 5acdbb3e-410e56e3-0000-000000000000 ("ISO (1)") 2011-11-30T06:40:08.242Z cpu6:2054)NFSLock: 608: Stop accessing fd 0x41000a4c3e68 3 2011-11-30T06:40:34.647Z cpu3:2051)NFSLock: 568: Start accessing fd 0x41000a4d8928 again 2011-11-30T06:44:42.663Z cpu1:2058)WARNING: NFS: 283: Lost connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:44:53.973Z cpu0:4011)NFS: 292: Restored connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:51:28.296Z cpu5:2058)NFSLock: 608: Stop accessing fd 0x41000ae3c528 3 2011-11-30T06:51:44.024Z cpu4:2052)NFSLock: 568: Start accessing fd 0x41000ae3b8e8 again 2011-11-30T06:56:30.758Z cpu4:2058)WARNING: NFS: 283: Lost connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:56:53.389Z cpu7:2055)NFS: 292: Restored connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T07:01:50.350Z cpu6:2054)ScsiDeviceIO: 2316: Cmd(0x41240072bc80) 0x12, CmdSN 0x9803 to dev "naa.600508e000000000505c16815a36c50d" failed H:0x0 D:0x2 P:0x0 Valid sense data: 0x5 0x24 0x0. 2011-11-30T07:03:48.449Z cpu3:2051)NFSLock: 608: Stop accessing fd 0x41000ae46b68 3 2011-11-30T07:03:57.318Z cpu4:4009)NFSLock: 568: Start accessing fd 0x41000ae48228 again (I've put a complete dump from one of the hosts on pastebin: http://pastebin.com/Vn60wgTt) When I got in the office at 9am, I saw various failures and alarms and troubleshooted the issue. It turned out that pretty much all of the VMs were inaccessible, and that the ESX hosts either were describing each VM as 'powered off', 'powered on', or 'unavailable'. The VMs described as 'powered on' where not in any way reachable or responding to pings, so this may be lies. There's absolutely no indication on the X1600 that anything was awry, and nothing on the switches to indicate any loss of connectivity. I only managed to resolve the issue by rebooting the ESX hosts in turn. I have a number of questions: What the hell happened? If this was a temporary NFS failure, why did it put the ESX hosts into a state from which a reboot was the only recovery? In the future, when the NFS server goes a little off-piste, what would be the best approach to add some resilience? I've been looking at budgeting for next year and potentially have budget to purchase another X1600/D2700/disks, would an identical mirrored disk setup help to mitigate these sorts of failures automatically? Edit (Added requested details) To expand with some details as requested: The X1600 has 12x 1TB disks lumped together in mirrored pairs as tank, and the D2700 (connected with a mini SAS cable) has 12x 300GB 10k SAS disks lumped together in mirrored pairs as sastank zpool status pool: rpool state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 c7t0d0s0 ONLINE 0 0 0 errors: No known data errors pool: sastank state: ONLINE scan: scrub repaired 0 in 74h21m with 0 errors on Wed Nov 30 02:51:58 2011 config: NAME STATE READ WRITE CKSUM sastank ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 c7t14d0 ONLINE 0 0 0 c7t15d0 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 c7t16d0 ONLINE 0 0 0 c7t17d0 ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 c7t18d0 ONLINE 0 0 0 c7t19d0 ONLINE 0 0 0 mirror-3 ONLINE 0 0 0 c7t20d0 ONLINE 0 0 0 c7t21d0 ONLINE 0 0 0 mirror-4 ONLINE 0 0 0 c7t22d0 ONLINE 0 0 0 c7t23d0 ONLINE 0 0 0 mirror-5 ONLINE 0 0 0 c7t24d0 ONLINE 0 0 0 c7t25d0 ONLINE 0 0 0 errors: No known data errors pool: tank state: ONLINE scan: scrub repaired 0 in 17h28m with 0 errors on Mon Nov 28 17:58:19 2011 config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 c7t1d0 ONLINE 0 0 0 c7t2d0 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 c7t3d0 ONLINE 0 0 0 c7t4d0 ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 c7t5d0 ONLINE 0 0 0 c7t6d0 ONLINE 0 0 0 mirror-3 ONLINE 0 0 0 c7t8d0 ONLINE 0 0 0 c7t9d0 ONLINE 0 0 0 mirror-4 ONLINE 0 0 0 c7t10d0 ONLINE 0 0 0 c7t11d0 ONLINE 0 0 0 mirror-5 ONLINE 0 0 0 c7t12d0 ONLINE 0 0 0 c7t13d0 ONLINE 0 0 0 errors: No known data errors The filesystem exposed over NFS for the primary datastore is sastank/VMStorage zfs list NAME USED AVAIL REFER MOUNTPOINT rpool 45.1G 13.4G 92.5K /rpool rpool/ROOT 2.28G 13.4G 31K legacy rpool/ROOT/solaris 2.28G 13.4G 2.19G / rpool/dump 15.0G 13.4G 15.0G - rpool/export 11.9G 13.4G 32K /export rpool/export/home 11.9G 13.4G 32K /export/home rpool/export/home/andrew 11.9G 13.4G 11.9G /export/home/andrew rpool/swap 15.9G 29.2G 123M - sastank 1.08T 536G 33K /sastank sastank/VMStorage 1.01T 536G 1.01T /sastank/VMStorage sastank/comstar 71.7G 536G 31K /sastank/comstar sastank/comstar/sql_tempdb 6.31G 536G 6.31G - sastank/comstar/sql_tx_data 65.4G 536G 65.4G - tank 4.79T 578G 42K /tank tank/FTP 269G 578G 269G /tank/FTP tank/ISO 28.8G 578G 25.9G /tank/ISO tank/backupstage 2.64T 578G 2.49T /tank/backupstage tank/cifs 301G 578G 297G /tank/cifs tank/comstar 1.54T 578G 31K /tank/comstar tank/comstar/msdtc 1.07G 579G 32.8M - tank/comstar/quorum 577M 578G 47.9M - tank/comstar/sqldata 1.54T 886G 304G - tank/comstar/vsphere_lun 2.09G 580G 22.2M - tank/mcs-asset-repository 7.01M 578G 6.99M /tank/mcs-asset-repository tank/mscs-quorum 55K 578G 36K /tank/mscs-quorum tank/sccm 16.1G 578G 12.8G /tank/sccm As for the networking, all connections between the X1600, the Blades and the switch are either LACP or Etherchannel bonded 2x 1Gbit links.

  • Computer is totally crashed

    - by Napster
    my computer kept restarting on its own at random times varying from 1 minutes, to 20 minutes(then goind in a constant restart loop every ~10 seconds). I had to turn it off and wait minutes or hours before attempting to restarting to go further in the boot process. Now, it just does not turn on. I posted this before: Computer crashes every 2 to 10 minutes but I did not have the time to check the temperature. I don't want to pay to get it checked up, but I want to know what is wrong. Is the processor fried? Thank you
