  • Install proprietary drivers 14.04 NVIDIA (steam segmentation issue)

    - by allthosemiles
    Recently, I finally got the official drivers for my NVIDIA 560 Ti card installed on Ubuntu 14.04 (hooray) However I started looking into installing Steam and I'm getting segmentation errors when I try to run the software. I tried installing 32-bit libs and it seemed like they weren't available or they were already installed. Upon further investigation, I found that a solution is to install the proprietary drivers, install steam then switch back to the other drivers. I'm not really sure what "proprietary drivers" are in all honesty. Has anyone gone through this process that could provide some insight here? (I installed the official 64-bit driver from the NVIDIA site for my 560 Ti just for reference. And the Ubuntu version installed is 64-bit as well) Update: This is the error text I get when trying to run steam after installing it via the ubuntu store. Running Steam on ubuntu 14.04 64-bit STEAM_RUNTIME is enabled automatically Installing breakpad exception handler for appid(steam)/version(1401381906_client) /home/dbrewer/.steam/steam.sh: line 755: 3943 Segmentation fault (core dumped) $STEAM_DEBUGGER "$STEAMROOT/$PLATFORM/$STEAMEXE" "$@" mv: cannot stat ‘/home/dbrewer/.steam/registry.vdf’: No such file or directory Installing bootstrap /home/dbrewer/.steam/bootstrap.tar.xz Reset complete!

  • Why do I need to create a bios-grub partition when I install 12.04?

    - by raj
    Is the bios-grub partition in Ubuntu 12.04 mandatory? I have used 11.04, 11.10 and 12.04, But I was never asked for this. Today I tried a fresh installation of Ubuntu 12.04 and for the first time I was asked for this Grub partition of minimum 1Mb. I first tried to reinstall 12.04, but the error continued. So I installed Fedora 16, Keeping all partitions as they were (replaced Ubuntu with Fedora), And then did another fresh installation of 12.04. Is it ok to continue with this grub partition or is there a fault in my system's hardware? If this is a (hardware) fault, how can I fix it? I'm using a Lenovo S10-2 Ideapad. The only OS right now installed is Ubuntu 12.04. well, let me answer. It was /usr/bin/xorg issue that I had with firstly installed precise. I used fedora16 basically for removing precise totally (my experience tells me ubuntu can't completely erase and reinstall by itself). this 1mb grub is created by fedora. I then wanted to remove it while reinstalling ubuntu but got caution bootloader may fail. hence I have to keep this 1mb drive. but prior to yesterday, i used both fedora and ubuntu, even same CDs, but had no such partition. my question is if this partition is necessary or not? if not, how can i safely remove it from my system? Am using only ubuntu 12.04 -- before and after (now).

  • Allocating memory inside a function and returning it back

    - by user2651062
    I want to pass a pointer to my function and allocate the memory to which this pointer points. I've read in other posts that I should pass a double pointer to this function and I did so, but I keep getting segmentation fault: #include <iostream> #include <stdlib.h> using namespace std; void allocate(unsigned char** t) { *t=(unsigned char*)malloc(3*sizeof(unsigned char)); if(*t == NULL) cout<<"Allcoation failed"<<endl; else for(int m=0;m<3;m++) *(t[m])=0; } int main() { unsigned char* t; allocate(&t); cout<<t[0]<<" "<<t[1]<<endl; return 0; } the result is always this: Segmentation fault (core dumped) I don't think that there's anything missing from this code. What could be wrong?

  • How should I host our scalable worker processes?

    - by Pieter Breed
    We are designing a new architecture for an enterprise business. The principles we've followed so far is not to develop what you can (possible buy and) deploy, ie, don't reinvent any wheels. In this way we've decided on CQRS, RabbitMQ, Riak and a bunch of other things. We still need to write /some/ business code though and these will be in the form of worker processes, which will consume commands from a message queue and after any side-effects, produce events onto another message queue. The idea behind this is that via the competing-consumers design we will have a scalable design right out of the box. One option is of writing a management infrastructure that will know how to: deploy code instantiate processes kill processes update configuration etc IE provide fault tolerance and scalability. Also, this is exactly what something like GAE and Heroku does for you, but in a public setting and in our organization, public is bad. My question is, is there an out-of-the-box solution that we can use to host our consumers in? Like a private cloud or private platform-as-a-service. Private Heroku or GAE. Is there some kind of software or software product with which we can do all of these things and thereby get scalability and fault tolerance over our consumers?

  • Valid reason for employer to breach freelance contract

    - by Costas
    Please don't close this as offtopic. According to the FAQ I can post programming related questions. I was working on a project and when it was half way completed (1 weeks work), the employer backs out and refuses to pay me. Shortly before this he was being very rude. He was having problems configuring the server and he told me it was my fault and that I had to fix it. After I spent several hours trying to figure out the problem, it turned out to be his fault. After this when I put the code on the server. He found 1 bug that I had missed. He freaked out, accused me of being a bad programmer and told me that the code was shit and that he couldn't use it. He said that if there is a bug in the code, that means the code is bad and he can't use it. He would have to throw the code away and hire someone else. His kept reiterating his argument: "why should I pay for code that I can't use". And I kept telling him the code was fine and urged him to have another programmer give him a second opinion. But he would have none of that. He said he would compensate me for my troubles by paying me 250$. Then he changes his mind and lowers that to 200$. Then a third time he changes his mind and says he doesn't want to compensate me at all. I'm left frustrated because besides being rude, he did not at any time tell me he was unhappy with the work that I was doing. So my question is; Is the above a valid reason to back out of a verbal contract in your opinion?

  • How to diagnose frequent segfaults

My first guess was that there's a Hardware problem of some sort and I asked my Hoster (it's a rented root server) to do a full hardwarecheck - they did, but couldn't find any problem. I don't know what and how they checked but their support team is usually quite good. I ran memtester and cpuburn myself and couldn't find any error either. Unfortunately I have no reliable way to reproduce these segfaults, they seem to be more or less random. On a hunch I disabled the firewall of the system and ran one of the programs that segfaulted regularily (imapsync) and it seemed to take longer to segfault than before, so the problem might be related to the network stack. Or could just be a random thing. Here are the kernel specs: # uname -a Linux gaz 2.6.32-5-amd64 #1 SMP Wed Jan 12 03:40:32 UTC 2011 x86_64 GNU/Linux # cat /etc/debian_version 6.0 # lsmod Module Size Used by cpufreq_userspace 1992 0 cpufreq_stats 2659 0 cpufreq_powersave 902 0 cpufreq_conservative 5162 0 xt_recent 5977 0 xt_tcpudp 2319 0 iptable_nat 4299 0 nf_nat 13388 1 iptable_nat nf_conntrack_ipv4 9833 3 iptable_nat,nf_nat nf_defrag_ipv4 1139 1 nf_conntrack_ipv4 ip6table_filter 2384 0 ip6_tables 15075 1 ip6table_filter xt_DSCP 1995 0 xt_TCPMSS 2919 0 ipt_LOG 4518 0 ipt_REJECT 1953 0 iptable_mangle 2817 0 iptable_filter 2258 0 xt_multiport 2267 0 xt_state 1303 0 xt_limit 1782 0 xt_conntrack 2407 0 nf_conntrack_ftp 5537 0 nf_conntrack 46535 6 iptable_nat,nf_nat,nf_conntrack_ipv4,xt_state,xt_conntrack,nf_conntrack_ftp ip_tables 13899 3 iptable_nat,iptable_mangle,iptable_filter x_tables 12845 13 xt_recent,xt_tcpudp,iptable_nat,ip6_tables,xt_DSCP,xt_TCPMSS,ipt_LOG,ipt_REJECT,xt_multiport,xt_state,xt_limit,xt_conntrack,ip_tables loop 11799 0 radeon 573996 0 ttm 39986 1 radeon drm_kms_helper 20065 1 radeon snd_hda_codec_atihdmi 2251 1 drm 142359 3 radeon,ttm,drm_kms_helper snd_hda_intel 20019 0 i2c_algo_bit 4225 1 radeon pcspkr 1699 0 i2c_piix4 8328 0 snd_hda_codec 54244 2 snd_hda_codec_atihdmi,snd_hda_intel i2c_core 15712 5 radeon,drm_kms_helper,drm,i2c_algo_bit,i2c_piix4 snd_hwdep 5380 1 snd_hda_codec snd_pcm 60503 2 snd_hda_intel,snd_hda_codec snd_timer 15582 1 snd_pcm snd 46446 5 snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_timer soundcore 4598 1 snd evdev 7352 3 snd_page_alloc 6249 2 snd_hda_intel,snd_pcm k8temp 3283 0 edac_core 29261 0 edac_mce_amd 6433 0 shpchp 26264 0 pci_hotplug 21203 1 shpchp button 4650 0 ext3 106518 2 jbd 37085 1 ext3 mbcache 5050 1 ext3 dm_mod 53754 0 powernow_k8 10978 1 aacraid 59779 0 3w_9xxx 28684 0 3w_xxxx 20569 0 raid10 17809 0 raid456 44500 0 async_raid6_recov 5170 1 raid456 async_pq 3479 2 raid456,async_raid6_recov raid6_pq 77179 2 async_raid6_recov,async_pq async_xor 2478 3 raid456,async_raid6_recov,async_pq xor 4380 1 async_xor async_memcpy 1198 2 raid456,async_raid6_recov async_tx 1734 5 raid456,async_raid6_recov,async_pq,async_xor,async_memcpy raid1 18431 3 raid0 5517 0 md_mod 73824 7 raid10,raid456,raid1,raid0 sata_nv 19166 0 sata_sil 7412 0 sata_via 7928 0 sd_mod 29889 8 crc_t10dif 1276 1 sd_mod ata_generic 3047 0 ahci 32374 6 r8169 29229 0 mii 3210 1 r8169 thermal 11674 0 pata_atiixp 3489 0 libata 133632 6 sata_nv,sata_sil,sata_via,ata_generic,ahci,pata_atiixp ohci_hcd 19212 0 ehci_hcd 31151 0 processor 29935 1 powernow_k8 thermal_sys 11942 2 thermal,processor scsi_mod 122149 5 aacraid,3w_9xxx,3w_xxxx,sd_mod,libata usbcore 122034 3 ohci_hcd,ehci_hcd nls_base 6377 1 usbcore # free total used free shared buffers cached Mem: 8166128 1228036 6938092 0 140412 782060 -/+ buffers/cache: 305564 7860564 Swap: 2102456 0 2102456 So, basically my questions are: How can I diagnose this further? Is there any data in the log above that could help me to isolate the troublemaker? Are there any known problems with the above hardware/software I overlooked when googling for it? Is there a way to prevent the kernel from autoloading modules (I probably don't need all these modules and one of them might be the culprit)

  • ls -l freezes terminal locally and remotely

    - by Jakobud
    I've been reading other SF threads regarding ls not returning results or freezing and stalling terminal sessions and it appears they usually the fault of network problems. My problem however, occurs both over remote SSH sessions but also if I am physically at the server itself... I just installed CentOS 5.4 on one of our servers. I'm setting up some rdiff-backup scripts and when I downloaded librsync and untared it, thats when I started seeing some weird behavior with ls -l. wget http://sourceforge.net/projects/librsync/files/librsync/0.9.7/librsync-0.9.7.tar.gz/download /tmp cd /tmp tar -xzf librsync-0.9.7.tar.gz Simple enough. To view the files in this directory I did this: ls results: librsync-0.9.7 librsync-0.9.7.tar.gz Now, if I ls -l, my terminal freezes. I have to re-ssh in to keep going. After reading SF threads, I thought it was network related. So I was extremely surprised to go sit down at the server itself and see the exact same thing happen... So its obviously not a network issues. Even if I ls /tmp/librsync-0.9.7, my terminal freezes just the same... Next I did an strace and got this (warning: wall of text coming....): strace ls -l /tmp execve("/bin/ls", ["ls", "-l", "/tmp"], [/* 21 vars */]) = 0 brk(0) = 0x1c521000 mmap(NULL, 4096,

  • Are there any USB flash drives or SD cards which use RAID or redundant storage for additional reliability?

    - by Luke Dennis
    I'm looking to get a fault-tolerant USB flash drive, which saves data to multiple independent locations, whether using RAID or some other means to back up data. Has a product like this ever been created, or are my only options to hack something together? (By the way: I'm aware that RAID doesn't prevent data corruption from software or the file system. I'm just looking for something that can handle one of the memory sticks going dead.)

  • Using a 20V power block on a 19V notebook

    - by user4444
    Is that dangerous : for the computer (without the battery) for the cells If possible, explain why. Edit : Here are some more assumptions : Without the battery included, there is no risk of overheating the cell, or over charging them. But there is still some dc to dc conversion taking place on the motherboard. I assume this dc to dc stage to be quite tolerant. What kind of trouble can I run into when using 20V instead of 19V ? Overheating ?

  • Computer Networks UNISA - Chap 15 &ndash; Network Management

    - by MarkPearl
    After reading this section you should be able to Understand network management and the importance of documentation, baseline measurements, policies, and regulations to assess and maintain a network’s health. Manage a network’s performance using SNMP-based network management software, system and event logs, and traffic-shaping techniques Identify the reasons for and elements of an asset managements system Plan and follow regular hardware and software maintenance routines Fundamentals of Network Management Network management refers to the assessment, monitoring, and maintenance of all aspects of a network including checking for hardware faults, ensuring high QoS, maintaining records of network assets, etc. Scope of network management differs depending on the size and requirements of the network. All sub topics of network management share the goals of enhancing the efficiency and performance while preventing costly downtime or loss. Documentation The way documentation is stored may vary, but to adequately manage a network one should at least record the following… Physical topology (types of LAN and WAN topologies – ring, star, hybrid) Access method (does it use Ethernet 802.3, token ring, etc.) Protocols Devices (Switches, routers, etc) Operating Systems Applications Configurations (What version of operating system and config files for serve / client software) Baseline Measurements A baseline is a report of the network’s current state of operation. Baseline measurements might include the utilization rate for your network backbone, number of users logged on per day, etc. Baseline measurements allow you to compare future performance increases or decreases caused by network changes or events with past network performance. Obtaining baseline measurements is the only way to know for certain whether a pattern of usage has changed, or whether a network upgrade has made a difference. There are various tools available for measuring baseline performance on a network. Policies, Procedures, and Regulations Following rules helps limit chaos, confusion, and possibly downtime. The following policies and procedures and regulations make for sound network management. Media installations and management (includes designing physical layout of cable, etc.) Network addressing policies (includes choosing and applying a an addressing scheme) Resource sharing and naming conventions (includes rules for logon ID’s) Security related policies Troubleshooting procedures Backup and disaster recovery procedures In addition to internal policies, a network manager must consider external regulatory rules. Fault and Performance Management After documenting every aspect of your network and following policies and best practices, you are ready to asses you networks status on an on going basis. This process includes both performance management and fault management. Network Management Software To accomplish both fault and performance management, organizations often use enterprise-wide network management software. There various software packages that do this, each collect data from multiple networked devices at regular intervals, in a process called polling. Each managed device runs a network management agent. So as not to affect the performance of a device while collecting information, agents do not demand significant processing resources. The definition of a managed devices and their data are collected in a MIB (Management Information Base). Agents communicate information about managed devices via any of several application layer protocols. On modern networks most agents use SNMP which is part of the TCP/IP suite and typically runs over UDP on port 161. Because of the flexibility and sophisticated network management applications are a challenge to configure and fine-tune. One needs to be careful to only collect relevant information and not cause performance issues (i.e. pinging a device every 5 seconds can be a problem with thousands of devices). MRTG (Multi Router Traffic Grapher) is a simple command line utility that uses SNMP to poll devices and collects data in a log file. MRTG can be used with Windows, UNIX and Linux. System and Event Logs Virtually every condition recognized by an operating system can be recorded. This is typically done using event logs. In Windows there is a GUI event log viewer. Similar information is recorded in UNIX and Linux in a system log. Much of the information collected in event logs and syslog files does not point to a problem, even if it is marked with a warning so it is important to filter your logs appropriately to reduce the noise. Traffic Shaping When a network must handle high volumes of network traffic, users benefit from performance management technique called traffic shaping. Traffic shaping involves manipulating certain characteristics of packets, data streams, or connections to manage the type and amount of traffic traversing a network or interface at any moment. Its goals are to assure timely delivery of the most important traffic while offering the best possible performance for all users. Several types of traffic prioritization exist including prioritizing traffic according to any of the following characteristics… Protocol IP address User group DiffServr VLAN tag in a Data Link layer frame Service or application Caching In addition to traffic shaping, a network or host might use caching to improve performance. Caching is the local storage of frequently needed files that would otherwise be obtained from an external source. By keeping files close to the requester, caching allows the user to access those files quickly. The most common type of caching is Web caching, in which Web pages are stored locally. To an ISP, caching is much more than just convenience. It prevents a significant volume of WAN traffic, thus improving performance and saving money. Asset Management Another key component in managing networks is identifying and tracking its hardware. This is called asset management. The first step to asset management is to take an inventory of each node on the network. You will also want to keep records of every piece of software purchased by your organization. Asset management simplifies maintaining and upgrading the network chiefly because you know what the system includes. In addition, asset management provides network administrators with information about the costs and benefits of certain types of hardware or software. Change Management Networks are always in a stage of flux with various aspects including… Software changes and patches Client Upgrades Shared Application Upgrades NOS Upgrades Hardware and Physical Plant Changes Cabling Upgrades Backbone Upgrades For a detailed explanation on each of these read the textbook (Page 750 – 761)

  • What Counts for A DBA: Observant

    - by drsql
    When walking up to the building where I work, I can see CCTV cameras placed here and there for monitoring access to the building. We are required to wear authorization badges which could be checked at any time. Do we have enemies?  Of course! No one is 100% safe; even if your life is a fairy tale, there is always a witch with an apple waiting to snack you into a thousand years of slumber (or at least so I recollect from elementary school.) Even Little Bo Peep had to keep a wary lookout.    We nerdy types (or maybe it was just me?) generally learned on the school playground to keep an eye open for unprovoked attack from simpler, but more muscular souls, and take steps to avoid messy confrontations well in advance. After we’d apprehensively negotiated adulthood with varying degrees of success, these skills of watching for danger, and avoiding it,  translated quite well to the technical careers so many of us were destined for. And nowhere else is this talent for watching out for irrational malevolence so appropriate as in a career as a production DBA.   It isn’t always active malevolence that the DBA needs to watch out for, but the even scarier quirks of common humanity.  A large number of the issues that occur in the enterprise happen just randomly or even just one time ever in a spurious manner, like in the case where a person decided to download the entire MSDN library of software, cross join every non-indexed billion row table together, and simultaneously stream the HD feed of 5 different sporting events, making the network access slow while the corporate online sales just started. The decent DBA team, like the going, gets tough under such circumstances. They spring into action, checking all of the sources of active information, observes the issue is no longer happening now, figures that either it wasn’t the database’s fault and that the reboot of the whatever device on the network fixed the problem.  This sort of reactive support is good, and will be the initial reaction of even excellent DBAs, but it is not the end of the story if you really want to know what happened and avoid getting called again when it isn’t even your fault.   When fires start raging within the corporate software forest, the DBA’s instinct is to actively find a way to douse the flames and get back to having no one in the company have any idea who they are.  Even better for them is to find a way of killing a potential problem while the fires are small, long before they can be classified as raging. The observant DBA will have already been monitoring the server environment for months in advance.  Most troubles, such as disk space and security intrusions, can be predicted and dealt with by alerting systems, whereas other trouble can come out of the blue and requires a skill of observing ongoing conditions and noticing inexplicable changes that could signal an emerging problem.  You can’t automate the DBA, because the bankable skill of a DBA is in detecting the early signs of unexpected problems, and working out how to deal with them before anyone else notices them.    To achieve this, the DBA will check the situation as it is currently happening,  and in many cases is likely to have been the person who submitted the problem to the level 1 support person in the first place, just to let the support team know of impending issues (always well received, I tell you what!). Database and host computer settings, configurations, and even critical data might be profiled and captured for later comparisons. He’ll use Monitoring tools, built-in, commercial (Not to be too crassly commercial or anything, but there is one such tool is SQL Monitor) and lots of homebrew monitoring tools to monitor for problems and changes in the server environment.   You will know that you have it right when a support call comes in and you can look at your monitoring tools and quickly respond that “response time is well within the normal range, the query that supports the failing interface works perfectly and has actually only been called 67% as often as normal, so I am more than willing to help diagnose the problem, but it isn’t the database server’s fault and is probably a client or networking slowdown causing the interface to be used less frequently than normal.” And that is the best thing for any DBA to observe…

  • Using multiple A-records for my domain - do web browsers ever try more than one?

    - by Jonas
    If I add multiple A-records for my domain, they are returned in a round robin order by DNS-servers. E.g: 1.1.1.1 A example.com 1.1.1.2 A example.com 1.1.1.3 A example.com But how does webbrowsers react if the first host (1.1.1.1) is down (unreachable)? do they try the second host (1.1.1.2) or do they return a error message to the user? Are there any difference between the most popular browsers? If I implement my own application, I can implement so that the second is used in case the first is down, so it's possible. And this would be very helpful to create a fault tolerant website.

  • Problems with tk85.dll when shutting down an application that embeds the Python interpreter.

    - by George Edison
    My C++ application embeds the Python interpreter, but seems to be having some trouble when it shuts down. Right after the main window closes, I get a segmentation fault (this is Windows, but we'll call it a segmentation fault anyway). The stack trace is below: #0 102AD580 tk85!Tk_MainWindow() (C:\Users\Nathan\Documents\Projects\PowerPad 1.3\bin\Debug\lib\tk85.dll:??) #1 103082DD tk85!XSetStipple() (C:\Users\Nathan\Documents\Projects\PowerPad 1.3\bin\Debug\lib\tk85.dll:??) #2 102214A3 ??() (C:\Users\Nathan\Documents\Projects\PowerPad 1.3\bin\Debug\lib\tk85.dll:??) #3 10220000 ??() (??:??) #4 00000000 ??() (??:??) Where would I even begin to debug this problem?

  • Does anybody actually use FaultReasonText to localize faults from WCF services?

    - by urig
    There is a localization mechanism in WCF that enables one to localize faults returned to client, via a FaultReasonText object that's a part of the fault. The way this is done is that you pass all possible translations of the fault's message inside a collection in the FaultReasonText. This, I understand, is based on SOAP v1.2. Does anyone actually use this mechanism? Isn't this wasteful in terms of bandwidth? Why would you send all possible translations to a client that is (probably) only interested in a specific language?

  • Flex/Flash 4 datagrid displays raw xml

    - by Setori
    Problem: Flex/Flash4 client (built with FlashBuilder4) displays the xml sent from the server exactly as is - the datagrid keeps the format of the xml. I need the datagrid to parse the input and place the data in the correct rows and columns of the datagrid. flow: click on a date in the tree and it makes a server request for batch information in xml form. Using a CallResponder I then update the datagrid's dataProvider. [code] <fx:Script> <![CDATA[ import mx.controls.Alert; [Bindable]public var selectedTreeNode:XML; public function taskTreeChanged(event:Event):void { selectedTreeNode=Tree(event.target).selectedItem as XML; var searchHubId:String = selectedTreeNode.@hub; var searchDate:String = selectedTreeNode.@lbl; if((searchHubId == "") || (searchDate == "")){ return; } findShipmentBatches(searchDate,searchHubId); } protected function findShipmentBatches(searchDate:String, searchHubId:String):void{ findShipmentBatchesResult.token = actWs.findShipmentBatches(searchDate, searchHubId); } protected function updateBatchDataGridDP():void{ task_list_dg.dataProvider = findShipmentBatchesResult.lastResult; } ]]> </fx:Script> <fx:Declarations> <actws:ActWs id="actWs" fault="Alert.show(event.fault.faultString + '\n' + event.fault.faultDetail)" showBusyCursor="true"/> <s:CallResponder id="findShipmentBatchesResult" result="updateBatchDataGridDP()"/> </fx:Declarations> <mx:AdvancedDataGrid id="task_list_dg" width="100%" height="95%" paddingLeft="0" paddingTop="0" paddingBottom="0"> <mx:columns> <mx:AdvancedDataGridColumn headerText="Receiving date" dataField="rd"/> <mx:AdvancedDataGridColumn headerText="Msg type" dataField="mt"/> <mx:AdvancedDataGridColumn headerText="SSD" dataField="ssd"/> <mx:AdvancedDataGridColumn headerText="Shipping site" dataField="sss"/> <mx:AdvancedDataGridColumn headerText="File name" dataField="fn"/> <mx:AdvancedDataGridColumn headerText="Batch number" dataField="bn"/> </mx:columns> </mx:AdvancedDataGrid> //xml example from server <batches> <batch> <rd>2010-04-23 16:31:00.0</rd> <mt>SC1REVISION01</mt> <ssd>2010-02-18 00:00:00.0</ssd> <sss>100000009</sss> <fn>Revision 1-DF-Ocean-SC1SUM-Quanta-PACT-EMEA-Scheduled Ship Date 20100218.csv</fn> <bn>10041</bn> </batch> <batches> [/code] and the xml is pretty much displayed exactly as is shown in the example above in the datagrid columns...

  • How can I troubleshoot an APPCRASH in Internet Explorer?

    - by Schnapple
    I'm writing an ActiveX control using the firebreath framework (hi taxilian!) and while it technically works, I'm running into a weird issue that appears to be unique to me. I've followed the instructions to create a simple plugin and then I ran it in Internet Explorer 8 on Windows 7 x64 (firebreath sets up a test page for the control). But as soon as I try to test it (clicking on a link that fires off JavaScript to interact with the control), IE crashes. Hard. "Internet Explorer has stopped working" style. If I try the control in Firefox (the resulting registered DLL can also be called as a Firefox plugin using a MIME type), it works fine. If I try it on my XP box, it works fine. I emailed the DLL and the testing page to a coworker in the next cube who is like me also running Windows 7 x64 and it works for him just fine as well, so it's not something unique to Windows 7 or x64. When it crashes I get this message: Problem signature: Problem Event Name: APPCRASH Application Name: iexplore.exe Application Version: 8.0.7600.16385 Application Timestamp: 4a5bc69e Fault Module Name: RPCRT4.dll Fault Module Version: 6.1.7600.16385 Fault Module Timestamp: 4a5bdb3b Exception Code: c0000005 Exception Offset: 000220b1 OS Version: 6.1.7600.2.0.0.256.1 Locale ID: 1033 Additional Information 1: 0a9e Additional Information 2: 0a9e372d3b4ad19135b953a78882e789 Additional Information 3: 0a9e Additional Information 4: 0a9e372d3b4ad19135b953a78882e789 Which tells me nothing extremely useful. I can have it attach to a debugger but it just tells me a long list of DLL's, none of which are the ActiveX control in question. It's almost like it's not even getting there. I did a sfc /scannow yesterday to see if anything on my system is corrupt and nothing came up as wrong. I tried various different security levels in IE, but nothing seems to have any effect. As this is a development machine there has been all matter of crap installed on it, so I figure it's bound to be something I've installed since October (when Win7 was released) but I cannot figure out what it is. I presume the information it's giving me when I attach to Visual Studio is useful somehow but I don't know how to interpret it. Admittedly I'm mainly a C#/.NET developer who's a bit out of his element with C/C++ and troubleshooting native code, but does anyone have any advice on how to proceed on figuring out why this very simple ActiveX control crashes IE on my machine and nowhere else?
