  • Raspberry Pi how to format HDD

    - by Speed
    Hi I am very new to Raspberry Pi environment, so looking for a bit of help to format a usb hard disk drive. I ran lsblk and got sda 8:0 0 37.3G 0 disk sda1 8:1 0 37.3G 0 part looking on web, if tried the following "sudo mkfs.ext4 /dev/sda1 -L USB40gb" it did something but when I tried to mount the drive again, it still showed the files that were there before and I can not create new file/folder "Error creating directory: Permission denied" I am writing this from my windows 8.1 pc so can not cut and paste from the pi. trying to format its output is a bit hard. Oh, there is Nothing written after the word "part" above. There use to be /media/USB40gb so I have done something because this has disappeared. I am using PCManFM 0.9.10 It does not have a format option, which would make life a lot easier, but then its not windows. I think I am running the basic linux os for the pi. It boots to a graphic environment, but I do not know how to advise what it is. I think its OpenBox 2.0.4 Thanks in advance Speed PS: I reran the format string above but this time I changed the label to read USB37gb. I did this to confirm that I was in fact formatting the right drive. Low and behold, it actually formatted the drive, wiping everything from it. Great ... testing it by creating a new folder on the drive and get error msg Permission Denied! So I have fixed the formatting issue by trial and error but still can't use the drive... Suggestions anyone?

  • Ubuntu 9.10 won't reboot after replacing a failed drive

    - by user149041
    Hello Serverfault community. I hope someone can shed light on a peculiar problem I am having with an Ubuntu 9.10 server install. I am not a Linux expert but have the responsibility of fixing the box if something goes wrong. DOH! I have Ubuntu 9.10 server installed on on a desktop platform: Compaq Presario SR5027CL. There are two 1TB SATA drives configured in a RAID 1 array; I use the box as an email backup server for a small group of users. Last week one of the drives failed and was replaced with a new drive of the same type. The problem I have been having is getting the box to reboot after a restart or a shutdown halt. The OS and the RAID 1 array are on the same drives that make up the RAID 1 array. The replacement drive (sda) was added to the box and the partitions were created to match the existing good drive (sdb). The array is made up of sda1 and sdb1. I found an interesting point while checking the BIOS settings: there is a "HDD Boot Group Priority" section, and the new drive was selected as the "1. 3rd master"; the server wouldn't boot configured like that, but when I set the old drive to be "1. 4th master", the box will reboot. I'm checking some more things, but I would certainly appreciate any useful information. Thanks in advance.

  • Adding SSD as boot drive to existing system

    - by thegrinner
    I recently bought two 128GB SSDs that I'm planning on adding (RAID 0) to a system I currently have on a 1TB HDD. I'm hoping to redo the disk space such that the SSDs act as the boot drive (only other items would be things I install there explicitly) while the majority of my system is on the HDD - documents, media, program files. Something like this: SSD = [ OS | Explicitly placed programs] HDD = [ Program Files | Media | Documents | etc] I have an external drive capable of holding all the data I want to save, so the backup isn't too much of a concern. What I'm worried about is how I should go about doing this - do I need to do a clean install on the SSDs, reformat the HDD, move things like Program Files/Users to the HDD, and then restore data (not full programs but things like saves)? Should I be using one of the regedit hacks I've seen around to change the default install directories instead of moving program files and users? Should I have the actual folders on the HDD and symlinks on the SSD? Or is there a better solution? Do I need to disconnect my HDD while doing the clean Windows install?

  • Windows Server 2008 (x64): Wont boot past bios page

    - by WebSolProv
    Happy New Year, Since a month or so ago I inherited responsibility for small network administration for my sins. The domain controller (yes there is only one, and yes I know it is best practice to have two even in a small domain setup) went down overnight and I have been trying all day to get it back up and running. Unfortunately this machine also administers our entire ActiveDirectory setup: 1) It goes thru the BIOS without any errors, nothing whatsoever 2) It gets into the “select safe mode, safe mode with networking, normal” etc and if you select either of the safe mode options it loads a few files then reboots. If you select normal it just runs for a bit (doesn’t get to the windows splash screen) and then reboots again. 3) If you select windows repair, it asks for an image to repair too: however it would appear that none was taken that can be used (!!) or one is not being shown. 4) I have tried repairing the boot sector and the boot configuration using Bootrec.exe, both which it says were completed successfully but still it doesn’t work. 5) I have tried swapping the drives into another server to rule out hardware and that didn’t work either so clearly it’s the OS. 6) I have tried running chkdsk which ran fine, and also memory check which was also fine. We do have another machine on the network that was installed as a DC so when we decommission the current infrastructure but when I try and "promote" this to the lead DC then I get “you cannot modify domain or trust information because a PDC emulator cannot be contacted" so I am unable to replicare the ActiveDirectory details. If anyone can think of any direction I should follow it would be greatly appreciated, Thanks, Alex

  • How to store Movies on a separate volume from the iTunes media folder?

    - by Manca Weeks
    I have a rather enormous Music collection. The music itself is approaching the 1TB mark. I am storing that on an external drive already. My iTunes library files are in their default location (/Users/me/Music/iTunes). My iTunes media folder is on an external drive /Volumes/iTunes/iTunes Music This has been working as expected. Now I would like to store just the contents of the Movies folder in the iTunes media folder on a separate drive. Apparently, iTunes doesn't like aliases or symlinks. I saw somewhere that one could mount a volume in a different directory than the default /Volumes. I would like to permanently mount my new Movies volume in the directory /Volumes/iTunes/iTunes Music/Movies. I know there is a command to do this, but how does one configure Mac OS 10.6.4 to always automatically mount that volume in this directory? I hope someone can enlighten me... If I find a solution, I can finally import all my movies into iTunes and be able to search them and stuff - it would be a dream. Thanks, M

  • Randomly unusable wireless connection. Oddest issue ever...

    - by Hallucynogenyc
    I have two desktop computers a laptop and a smartphone. All of them connect perfectly to my router (WRT54GL with Tomato firmware), but randomly (once a week maybe) something odd happens: For over an hour or so one of the desktop computers (Windows 7 Pro x64) will just refuse to connect properly to the router. Only that computer and only to that network. I can connect all the other machines to the router perfectly and I can connect properly to other networks with that machine. What I mean by "not being able to connect properly" I mean that the OS will just tell me "not able to connect to.." or that it will connect but then say that it has no Internet access or it connects but will then take minutes to load any website, even the router web interface. I've tried to change from WPA2 to WEP and back to WPA2, I've tried different network adapters (one internal PCI card and one USB external card), removing networks from Windows and adding again... without making any difference. It works for some days but at the end, it ends happening at some time. I just have no clue on what the hell could be going on here. I first thought it was the network adapter, then the router, then Windows... Thanks in advance

  • Folder doesn't show up in explorer, cmd, and python even though I can access it, how can I fix this?

    - by Miebster
    I am accessing another computer on the network using a mapped network drive. The path looks like \\192.168.0.100\d$ which is mapped to my computer's "m" drive. I can access, view, create, delete, move, etc folders on this drive. However, some folders don't show up in windows explorer, even tho I can access them. Example: Lets say that M:\stuff\more_stuff is a directory. What I can't do: When windows explorer is pointed at M:\stuff I can't see more_stuff In cmd prompt pointed at M:\stuff "dir" doesn't find more_stuff In cmd prompt pointed at M:\stuff "dir /a" doens't find more_stuff In python, os.listdir at M:\stuff doens't find more_stuff What I can do: Typing M:\stuff\more_stuff into the address bar lets me access the folder like normal. Because there is no indication that this folder even exists, there could be more like them. I have no way of knowing how many folders are magically hidden on this mapped drive. What are some steps I can do to figure out why this folder is hidden? (With the end goal of making it no longer hidden).

  • How many VPS do I need for my website? [duplicate]

    - by michael
    This question already has an answer here: How do you do load testing and capacity planning for web sites? 3 answers I made a website which aims at simulating a trading market. There are a list of prices and corresponding volumes that people want to purchase. Users can purchase at any price any time. My website retrieves the prices and volumes from my database every 2 seconds (I have to update the user's browser frequently to allow them to see the current market). Users' database INSERT query can be sent any time if they purchase. I used ajax to post or get data from my database (sometimes nested ajax calls). So, every 2 seconds, each user will send or retrieve data by using more than 20 database queries (in order to show a users the current prices and volumes). Also, I may have 200 users at a time. I was not using VPS before, and I got banned because of using too much CPU resources on my host. Now, I've purchased VPS*2 from a hosting servers. I have: CPU Speed: 2000 Mhz Memory: 2048 MB Disk Space: 20000 MB Bandwidth: 2000 GB Connection: 40 Mb/s Dedicated IP's 2 IP's Is this enough for my 200 users? Also, which VPS OS is suitable for me? Thank you.

  • Windows 7 constantly accessing hard drive [duplicate]

    - by Zohar
    Possible Duplicate: Tool which finds which process is causing the heavy hard drive activity? Did you notice that on Windows 7 (I use 64-bit) the hard drive LED is constantly blinking, which means that the OS is constantly wearing the hard drive by accessing it? It's something related to the system process, and it even occurs in safe mode, so I don't think it's a third party software problem. Has anyone experienced this problem as well, and is it a Windows problem, or caused by something else? Edit: My indexing service is reduced to indexing only the Start Menu. Even if it was set for the whole computer, it would eventually stop; that's not it. My friends also suffer from the same problem. Please answer my first question: have any of you have seen a Windows 7 machine whose hard drive LED is at rest? I'm also trying to track down the offending process using procmon and Resource Monitor, and it actually seems like a system process. It could also be svchost.exe, and I'm not sure which file they are accessing since I see a lot of activity which I can't make sense of. It's loading system DLLs, accessing registry keys, and other nonsense.

  • Scrum Master Stephen Forte Teaches Agile Development, Silverlight and BI at GIDS 2010

    - by rajesh ahuja
    Great Indian Developer Summit 2010 – Gold Standard for India's Software Developer Ecosystem Bangalore, March 25, 2010: The author of several books on application and database development including Programming SQL Server 2008 and certified Scrum Master Stephen Forte is coming this summer to India's biggest summit for the developer ecosystem - Great Indian Developer Summit. At the summit, Stephen will conduct a workshop guaranteed to give attendees a jump start in taking a certified scrum master exam. Scrum, one of the most popular Agile project management and development methods, which is starting to be adopted at major corporations and on very large projects. After an introduction to the basics of Scrum like project planning and estimation, the Scrum Master, team, product owner and burn down, and of course the daily Scrum, Stephen will show many real world applications of the methodology drawn from his own experience as a Scrum Master. Negotiating with the business, estimation and team dynamics are all discussed as well as how to use Scrum in small organizations, large enterprise environments and consulting environments. Stephen will also discuss using Scrum with virtual teams and an off-shoring environment. He will then take a look at the tools we will use for Agile development, including planning poker, unit testing, and much more. On 20th April at the GIDS.NET Conference, Stephen will also conduct a series of sessions on Microsoft computing technologies. He will teach how to build data driven, n-tier Rich Internet Applications (RIA) with Silverlight 4.0. Line of business applications (LOB) in Silverlight 4.0 are easy by tapping the power of WCF RIA Services, the Silverlight Toolkit, and elevated out of browser support. Stephen's demo centric session will walk you through an example of building a LOB application with Silverlight 4.0. See how Silverlight and WCF RIA Services support domain logic, services, data binding, validation, server based paging, authentication, authorization and much more. Silverlight 4.0 means business. Silverlight runs C# and Visual Basic code, and so it seems natural that a business application might share some code between the Silverlight client and its ASP.NET Web server. You may want to run some code client-side for interactivity, but re-run that code on the server for security or reliability. This is possible, and there are several techniques you can use to accomplish this goal. In Stephen's second talk learn about the various techniques and their pros and cons. Some techniques work better in C#, others in VB. Still others are simpler with a little extra tooling or code-generation. Any serious Silverlight business application will almost certainly face this issue, and this session gets you going fast. In the third talk, Stephen will explain how to properly architect and deploy a BI application using a mix of some exciting new tools and some old familiar ones. He will start with a traditional relational transaction centric database (OLTP) and explore ways to build a data warehouse (OLAP), looking at the star and snowflake schemas. Next he will look at the process of extraction, transformation, and loading (ETL) your OLTP data into your data warehouse. Different techniques for ETL will be described and the various tradeoffs will be discussed. Then he will look at using the warehouse for reporting, drill down, and data analysis in Microsoft Excel's PowerPivot 2010. The session will round off by showing how to properly build a cube and build a data analysis application on top of that cube, and conclude by looking at some tools to help with the data visualization process.

  • Too nervous to install

    - by The Prop
    Yesterday I (a professional rugby prop of somewhat limited intellect) landed in http://htmlagilitypack.codeplex.com/ and found myself stranded in a town with no signposts. The locals don't need signposts - they know their way around - so who gives a hoot about visitors? Well I'm a visitor and I'm lost. Here's my plea to the good burgesses of Codeplex-sans-signs: HELP!! Let me back-track and explain what landed me at the bottom of this tangled ruck. There's a "Download" button positioned near the top-right of the Codeplex web page, right? Like the Sword of Damocles, a down-arrow to the left of the button indicates, presumably, what a download would include: CURRENT 1.4.0 Stable DATE Fri May 7 2010 at 7:00 AM STATUS Stable With a simple-minded confidence that has since deserted me (the confidence - not the simple-mindedness), I clicked "Download". This introduced 3 new files to my computer: HtmlAgilityPack.dll, HtmlAgilityPack.pdb, and HtmlAgilityPack.XML This is when the first stab of doubt penetrated that globe between my cauliflower ears that I call a head. Where's the dot cs? Somewhere in Codeplex, I'd read advice to another lost soul to "download and build the HTMLAgilityPack solution". As I've done so many times as an All Black prop, I glared at the opposition front row - ah, I mean the 3 new files. Shouldn't one of them have a ".cs" on the back of his jersey - er, on the end of its name? Or is this just how they play the game in Codeplex-sans-signs? Undaunted (props have more courage than sense) I packed into my first C# scrum. The half-back feeds the ball in, and the front rows collapse - er, the debugging stops at this line of my code: "HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();" Then the Referee blows his whistle and announces one of those verdicts that's utterly indecipherable to your average loose-head prop: Locating source for 'C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\HtmlDocument.cs'. Checksum: MD5 {62 bc f3 7e 9a 92 a6 32 7 d6 5b f8 76 59 7b 5b} The file 'C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\HtmlDocument.cs' does not exist. Looking in script documents for 'C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\HtmlDocument.cs'... Looking in the projects for 'C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\HtmlDocument.cs'. The file was not found in a project. Looking in directory 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\vc7\atlmfc'... Looking in directory 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\vc7\crt'... The debugger will ask the user to find the file: C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\HtmlDocument.cs. The user pressed Cancel [a brain-stemmer from the prop] in the Find Source dialog. The debug source files settings for the active solution have been modified so that the debugger will not ask the user to find the file: C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\HtmlDocument.cs. The debugger could not locate the source file 'C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\HtmlDocument.cs'. Even if it had been the first 50 stanzas of "Eskimo Nell", I couldn't have been more shocked. I'm so shocked, my jaws clamp shut around the opposition hooker's ear. He thumbs me in the iris. With a cornea-torn eye I peer at the Codeplex site. My brain stem sparks and I punch the "View all downloads" link. It sparks four more times on each download link, and.. lo! FOUR files this time: HAPExplorer.zip, HtmlAgilityPack.1.4.0.Source.zip, HtmlAgilityPack.1.4.0.zip, HtmlAgilityPack.Documentation.chm But... is this not the same place arrived at recently by my flat-mate Chaz, journalist extraordinaire? (Chaz, if you're reading this, I'm not plugging for nothing - just write kindly about me in your next report, okay?) Didn't these same four files flummox Chaz The Great? He told me about it. Chaz left a message with Codeplex and then solved the problem by just walking away. Typical journalist, huh. But I'm not like that. I don't walk away. I'm made of the sort of stubborn stuff that becomes an All Black prop. Hence this impassioned plea: GOOD TOWNSFOLK OF CODEPLEX-SANS-SIGNS, WHAT SHOULD I DO NEXT? Can somebody point me to Main Street? How does a simpleton install 'C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\HtmlDocument.cs'? I'm willing to prostrate myself and grovel to the first kind face that passes in front of my rapidly clouding sight. So help me, I'd even tug my forelock if I had one! Should I hold forth my rod over the wilderness, and create a folder called 'C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\' or some such? If so, what files should I move into it? ANYTHING else a dum-ass should know about? - and I mean ANYTHING - you just don't know how witless a punch-drunk prop can be.. %( Whenever I've installed other programs they've given me an ".exe" or ".msi" that I can click on and it's all done for me like magic. HEY... there's nothing of that nature here, is there? Am I missing something? Something for dummies to click? (From the waiting rooms of Dr I. Sight Phixes) (signed) The Prop

  • Cannot use WCF service from windows mobile 5: no endpoint found.

    - by sweeney
    Hi All, I'm trying to figure out how to call a WCF service from a windows smart phone. I have a very simple smartphone console app, which does nothing but launch and make 1 call to the service. The service simply returns a string. I am able to instantiate the proxy class but when i call the method it throws an exception: There was no endpoint listening at http://mypcname/Service1.svc/basic that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. The inner exception: Could not establish connection to network. I've tried to follow this tutorial on setting up services with windows mobile. I've used the NetCFSvcUtil to create the proxy classes. I have the service running on IIS on my machine and had the Util consume the wsdl from that location. I've created a basic http binding as suggested in the article and i think i've pointed the proxy at the correct uri. Here some sections of relevant code in case it's helpful to see. If anyone has any suggestions, i'd really appreciate it. I'm not sure what else i can poke at to get this thing to work. Thanks! Client, (Program.cs): using System; using System.Linq; using System.Collections.Generic; using System.Text; namespace WcfPoC { class Program { static void Main(string[] args) { try { Service1Client proxy = new Service1Client(); string test = proxy.GetData(5); } catch (Exception e) { Console.WriteLine(e.Message); Console.WriteLine(e.InnerException.Message); Console.WriteLine(e.StackTrace); } } } } Client Proxy excerpt (Service1.cs): [System.Diagnostics.DebuggerStepThroughAttribute()] [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")] public partial class Service1Client : Microsoft.Tools.ServiceModel.CFClientBase<IService1>, IService1 { //modified according to the walk thru linked above... public static System.ServiceModel.EndpointAddress EndpointAddress = new System.ServiceModel.EndpointAddress("http://boston7/Service1.svc/basic"); /* *a bunch of code create by the svc util - left unmodified */ } The Service (Service1.svc.cs): using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.Text; namespace WcfService1 { // NOTE: If you change the class name "Service1" here, you must also update the reference to "Service1" in Web.config and in the associated .svc file. public class Service1 : IService1 { public string GetData(int value) //i'm calling this one... { return string.Format("You entered: {0}", value); } public CompositeType GetDataUsingDataContract(CompositeType composite) { if (composite.BoolValue) { composite.StringValue += "Suffix"; } return composite; } } } Service Interface (IService1.cs): using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.Text; namespace WcfService1 { // NOTE: If you change the interface name "IService1" here, you must also update the reference to "IService1" in Web.config.

  • Hung JVM consuming 100% CPU

    - by Bogdan
    We have a JAVA server running on Sun JRE 6u20 on Linux 32-bit (CentOS). We use the Server Hotspot with CMS collector with the following options (I've only provided the relevant ones): -Xmx896m -Xss128k -XX:NewSize=384M -XX:MaxPermSize=96m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC Sometimes, after running for a while, the JVM seems to slip into a hung state, whereby even though we don't make any requests to the application, the CPU continues to spin at 100% (we have 8 logical CPUs, so it looks like only one CPU does the spinning). In this state the JVM doesn't respond to SIGHUP signals (kill -3) and we can't connect to it normally with jstack. We CAN connect with "jstack -F", but the output is dodgy (we can see lots of NullPointerExceptions from JStack apparently because it wasn't able to 'walk' some stacks). So the "jstack -F" output seems to be useless. We have run a stack dump from "gdb" though, and we were able to match the thread id that spins the CPU (we found that using "top" with a per-thread view - "H" option) with a thread stack that appears in the gdb result and this is how it looks like: Thread 443 (Thread 0x7e5b90 (LWP 26310)): #0 0x0115ebd3 in CompactibleFreeListSpace::block_size(HeapWord const*) const () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #1 0x01160ff9 in CompactibleFreeListSpace::prepare_for_compaction(CompactPoint*) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #2 0x0123456c in Generation::prepare_for_compaction(CompactPoint*) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #3 0x01229b2c in GenCollectedHeap::prepare_for_compaction() () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #4 0x0122a7fc in GenMarkSweep::invoke_at_safepoint(int, ReferenceProcessor*, bool) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #5 0x01186024 in CMSCollector::do_compaction_work(bool) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #6 0x011859ee in CMSCollector::acquire_control_and_collect(bool, bool) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #7 0x01185705 in ConcurrentMarkSweepGeneration::collect(bool, bool, unsigned int, bool) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #8 0x01227f53 in GenCollectedHeap::do_collection(bool, bool, unsigned int, bool, int) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #9 0x0115c7b5 in GenCollectorPolicy::satisfy_failed_allocation(unsigned int, bool) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #10 0x0122859c in GenCollectedHeap::satisfy_failed_allocation(unsigned int, bool) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #11 0x0158a8ce in VM_GenCollectForAllocation::doit() () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #12 0x015987e6 in VM_Operation::evaluate() () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #13 0x01597c93 in VMThread::evaluate_operation(VM_Operation*) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #14 0x01597f0f in VMThread::loop() () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #15 0x015979f0 in VMThread::run() () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #16 0x0145c24e in java_start(Thread*) () from /usr/java/jdk1.6.0_20/jre/lib/i386/server/libjvm.so #17 0x00ccd46b in start_thread () from /lib/libpthread.so.0 #18 0x00bc2dbe in clone () from /lib/libc.so.6 It seems that a JVM thread is spinning while doing some CMS related work. We have checked the memory usage on the box, there seems to be enough memory available and the system is not swapping. Has anyone come across such a situation? Does it look like a JVM bug? UPDATE I've obtained some more information about this problem (it happened again on a server that has been running for more than 7 days). When the JVM entered the "hung" state it stayed like that for 2 hours until the server was manually restarted. We have obtained a core dump of the process and the gc log. We tried to get a heap dump as well, but "jmap" failed. We tried to use jmap -F but then only a 4Mb file was written before the program aborted with an exception (something about the a memory location not being accessible). So far I think the most interesting information comes from the gc log. It seems that the GC logging stopped as well (possibly at the time when the VM thread went into the long loop): 657501.199: [Full GC (System) 657501.199: [CMS: 400352K->313412K(524288K), 2.4024120 secs] 660634K->313412K(878208K), [CMS Perm : 29455K->29320K(68568K)], 2.4026470 secs] [Times: user=2.39 sys=0.01, real=2.40 secs] 657513.941: [GC 657513.941: [ParNew: 314624K->13999K(353920K), 0.0228180 secs] 628036K->327412K(878208K), 0.0230510 secs] [Times: user=0.08 sys=0.00, real=0.02 secs] 657523.772: [GC 657523.772: [ParNew: 328623K->17110K(353920K), 0.0244910 secs] 642036K->330523K(878208K), 0.0247140 secs] [Times: user=0.08 sys=0.00, real=0.02 secs] 657535.473: [GC 657535.473: [ParNew: 331734K->20282K(353920K), 0.0259480 secs] 645147K->333695K(878208K), 0.0261670 secs] [Times: user=0.11 sys=0.00, real=0.02 secs] .... .... 688346.765: [GC [1 CMS-initial-mark: 485248K(524288K)] 515694K(878208K), 0.0343730 secs] [Times: user=0.03 sys=0.00, real=0.04 secs] 688346.800: [CMS-concurrent-mark-start] 688347.964: [CMS-concurrent-mark: 1.083/1.164 secs] [Times: user=2.52 sys=0.09, real=1.16 secs] 688347.964: [CMS-concurrent-preclean-start] 688347.969: [CMS-concurrent-preclean: 0.004/0.005 secs] [Times: user=0.00 sys=0.01, real=0.01 secs] 688347.969: [CMS-concurrent-abortable-preclean-start] CMS: abort preclean due to time 688352.986: [CMS-concurrent-abortable-preclean: 2.351/5.017 secs] [Times: user=3.83 sys=0.38, real=5.01 secs] 688352.987: [GC[YG occupancy: 297806 K (353920 K)]688352.987: [Rescan (parallel) , 0.1815250 secs]688353.169: [weak refs processing, 0.0312660 secs] [1 CMS-remark: 485248K(524288K)] 783055K(878208K), 0.2131580 secs] [Times: user=1.13 sys =0.00, real=0.22 secs] 688353.201: [CMS-concurrent-sweep-start] 688353.903: [CMS-concurrent-sweep: 0.660/0.702 secs] [Times: user=0.91 sys=0.07, real=0.70 secs] 688353.903: [CMS-concurrent-reset-start] 688353.912: [CMS-concurrent-reset: 0.008/0.008 secs] [Times: user=0.01 sys=0.00, real=0.01 secs] 688354.243: [GC 688354.243: [ParNew: 344928K->30151K(353920K), 0.0305020 secs] 681955K->368044K(878208K), 0.0308880 secs] [Times: user=0.15 sys=0.00, real=0.03 secs] .... .... 688943.029: [GC 688943.029: [ParNew: 336531K->17143K(353920K), 0.0237360 secs] 813250K->494327K(878208K), 0.0241260 secs] [Times: user=0.10 sys=0.00, real=0.03 secs] 688950.620: [GC 688950.620: [ParNew: 331767K->22442K(353920K), 0.0344110 secs] 808951K->499996K(878208K), 0.0347690 secs] [Times: user=0.11 sys=0.00, real=0.04 secs] 688956.596: [GC 688956.596: [ParNew: 337064K->37809K(353920K), 0.0488170 secs] 814618K->515896K(878208K), 0.0491550 secs] [Times: user=0.18 sys=0.04, real=0.05 secs] 688961.470: [GC 688961.471: [ParNew (promotion failed): 352433K->332183K(353920K), 0.1862520 secs]688961.657: [CMS I suspect this problem has something to do with the last line in the log (I've added some "...." in order to skip some lines that were not interesting). The fact that the server stayed in the hung state for 2 hours (probably trying to GC and compact the old generation) seems quite strange to me. Also, the gc log stops suddenly with that message and nothing else gets printed any more, probably because the VM Thread gets into some sort of infinite loop (or something that takes 2+ hours).

  • Apache Tomcat Ant undeploy task error using

    - by Devil Jin
    I am using ant 1.7 to deploy and undeploy applications in tomcat //Snippet from my build.xml <target name="deploy" depends="war" description="Install application to the servlet containor"> <deploy url="${tomcat.manager.url}" username="${manager.user}" password="${manager.passwd}" path="/${tomcat.ctxpath}" war="${war.local}" /> </target> <target name="undeploy" description="Removes Web Application from path"> <undeploy url="${tomcat.manager.url}" username="${manager.user}" password="${manager.passwd}" path="/${tomcat.ctxpath}" /> </target> The deploy task works perfectly fine but the undeploy task gives an html output for the undeploy task prefixed with [undeploy] although the application is undeployed successfully The html message also contains the success message 'OK - Undeployed application at context path /MyApplication' OUTPUT: [undeploy] <html> [undeploy] <head> [undeploy] <style> [undeploy] H1 {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;font-size:22px;} H2 {font-family:Tah oma,Arial,sans-serif;color:white;background-color:#525D76;font-size:16px;} H3 {font-family:Tahoma,Arial,sans-serif;color:whit e;background-color:#525D76;font-size:14px;} BODY {font-family:Tahoma,Arial,sans-serif;color:black;background-color:white;} B {font-family:Tahoma,Arial,sans-serif;color:white;background-color:#525D76;} P {font-family:Tahoma,Arial,sans-serif;background :white;color:black;font-size:12px;}A {color : black;}A.name {color : black;}HR {color : #525D76;} table { [undeploy] width: 100%;

  • Trying to use json to populate areas of my website using mysql, php, and jquery.

    - by RyanPitts
    Ok, so this is my first attempt at doing anything with JSON. I have done a lot with PHP and MySql as well as jQuery and JavaScript...but nothing with JSON. I have some data in a MySql database. In the codes below i am using a PHP file to retrieve the data from the MySql database and using json_encode to format it to JSON. This file is being called by the JavaScript that runs when the page loads (well, it runs on document.ready actually). I then use jQuery to access the JSON keys and values to fill in areas of the page "dynamically". Here is the code snippets i am using (excuse my "noobness" on writing these snippets, still learning all this). This is my script that is on my HTML page test.php: <script type="text/javascript"> $(document).ready(function(){ $.getJSON("json_events.php",function(data){ $.each(data.events, function(i,events){ var tblRow = "<tr>" +"<td>" + events.id + "</td>" +"<td>" + events.customerId + "</td>" +"<td>" + events.filingName + "</td>" +"<td>" + events.title + "</td>" +"<td>" + events.details + "</td>" +"<td>" + events.dateEvent + "</td>" +"<td><a href='assets/customers/testchurch/events/" + events.image + "'>" + events.image + "</a></td>" +"<td>" + events.dateStart + "</td>" +"<td>" + events.dateEnd + "</td>" +"</tr>" $(tblRow).appendTo("#eventsdata tbody"); }); }); $.getJSON("json_events.php",function(data){ $.each(data.events, function(i,events){ $("#title").html("First event title: " + events.title + " ..."); }); }); }); </script> This is the code for the php file being called by the above JS: json_events.php <?php require_once('includes/configread.php'); $arrayEvents = array(); $resultsEvents = mysql_query("SELECT * FROM events"); while($objectEvents = mysql_fetch_object($resultsEvents)) { $arrayEvents[] = $objectEvents; } $json_object_events = json_encode($arrayEvents); $json_events = "{\"events\": " . $json_object_events . " }"; echo $json_events; require_once('includes/closeconnread.php'); ?> This is my JSON that is held in the variable $json_events from my php file json_events.php: { "events": [ { "id": "2", "customerId": "1004", "filingName": "testchurch", "title": "Kenya 2011 Training Meeting", "details": "This meeting will be taking place on Sunday, February 10th @ 6pm.

Question 1: Does this code look like it is written correctly at first glance? Question 2: I want to be able to select only the title from the first event in the JSON array. The code i am using now is selecting the second events' title by default it seems. How can i accomplish this?

  • Using the jQuery UI Library in a MVC 3 Application to Build a Dialog Form

    - by ChrisD
    Using a simulated dialog window is a nice way to handle inline data editing. The jQuery UI has a UI widget for a dialog window that makes it easy to get up and running with it in your application. With the release of ASP.NET MVC 3, Microsoft included the jQuery UI scripts and files in the MVC 3 project templates for Visual Studio. With the release of the MVC 3 Tools Update, Microsoft implemented the inclusion of those with NuGet as packages. That means we can get up and running using the latest version of the jQuery UI with minimal effort. To the code! Another that might interested you about JQuery Mobile and ASP.NET MVC 3 with C#. If you are starting with a new MVC 3 application and have the Tools Update then you are a NuGet update and a <link> and <script> tag away from adding the jQuery UI to your project. If you are using an existing MVC project you can still get the jQuery UI library added to your project via NuGet and then add the link and script tags. Assuming that you have pulled down the latest version (at the time of this publish it was 1.8.13) you can add the following link and script tags to your <head> tag: < link href = "@Url.Content(" ~ / Content / themes / base / jquery . ui . all . css ")" rel = "Stylesheet" type = "text/css" /> < script src = "@Url.Content(" ~ / Scripts / jquery-ui-1 . 8 . 13 . min . js ")" type = "text/javascript" ></ script > The jQuery UI library relies upon the CSS scripts and some image files to handle rendering of its widgets (you can choose a different theme or role your own if you like). Adding these to the stock _Layout.cshtml file results in the following markup: <!DOCTYPE html> < html > < head >     < meta charset = "utf-8" />     < title > @ViewBag.Title </ title >     < link href = "@Url.Content(" ~ / Content / Site . css ")" rel = "stylesheet" type = "text/css" />     <link href="@Url.Content("~/Content/themes/base/jquery.ui.all.css")" rel="Stylesheet" type="text/css" />     <script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script>     <script src="@Url.Content("~/Scripts/modernizr-1.7.min . js ")" type = "text/javascript" ></ script >     < script src = "@Url.Content(" ~ / Scripts / jquery-ui-1 . 8 . 13 . min . js ")" type = "text/javascript" ></ script > </ head > < body >     @RenderBody() </ body > </ html > Our example will involve building a list of notes with an id, title and description. Each note can be edited and new notes can be added. The user will never have to leave the single page of notes to manage the note data. The add and edit forms will be delivered in a jQuery UI dialog widget and the note list content will get reloaded via an AJAX call after each change to the list. To begin, we need to craft a model and a data management class. We will do this so we can simulate data storage and get a feel for the workflow of the user experience. The first class named Note will have properties to represent our data model. namespace Website . Models {     public class Note     {         public int Id { get ; set ; }         public string Title { get ; set ; }         public string Body { get ; set ; }     } } The second class named NoteManager will be used to set up our simulated data storage and provide methods for querying and updating the data. We will take a look at the class content as a whole and then walk through each method after. using System . Collections . ObjectModel ; using System . Linq ; using System . Web ; namespace Website . Models {     public class NoteManager     {         public Collection < Note > Notes         {             get             {                 if ( HttpRuntime . Cache [ "Notes" ] == null )                     this . loadInitialData ();                 return ( Collection < Note >) HttpRuntime . Cache [ "Notes" ];             }         }         private void loadInitialData ()         {             var notes = new Collection < Note >();             notes . Add ( new Note                           {                               Id = 1 ,                               Title = "Set DVR for Sunday" ,                               Body = "Don't forget to record Game of Thrones!"                           });             notes . Add ( new Note                           {                               Id = 2 ,                               Title = "Read MVC article" ,                               Body = "Check out the new iwantmymvc.com post"                           });             notes . Add ( new Note                           {                               Id = 3 ,                               Title = "Pick up kid" ,                               Body = "Daughter out of school at 1:30pm on Thursday. Don't forget!"                           });             notes . Add ( new Note                           {                               Id = 4 ,                               Title = "Paint" ,                               Body = "Finish the 2nd coat in the bathroom"                           });             HttpRuntime . Cache [ "Notes" ] = notes ;         }         public Collection < Note > GetAll ()         {             return Notes ;         }         public Note GetById ( int id )         {             return Notes . Where ( i => i . Id == id ). FirstOrDefault ();         }         public int Save ( Note item )         {             if ( item . Id <= 0 )                 return saveAsNew ( item );             var existingNote = Notes . Where ( i => i . Id == item . Id ). FirstOrDefault ();             existingNote . Title = item . Title ;             existingNote . Body = item . Body ;             return existingNote . Id ;         }         private int saveAsNew ( Note item )         {             item . Id = Notes . Count + 1 ;             Notes . Add ( item );             return item . Id ;         }     } } The class has a property named Notes that is read only and handles instantiating a collection of Note objects in the runtime cache if it doesn't exist, and then returns the collection from the cache. This property is there to give us a simulated storage so that we didn't have to add a full blown database (beyond the scope of this post). The private method loadInitialData handles pre-filling the collection of Note objects with some initial data and stuffs them into the cache. Both of these chunks of code would be refactored out with a move to a real means of data storage. The GetAll and GetById methods access our simulated data storage to return all of our notes or a specific note by id. The Save method takes in a Note object, checks to see if it has an Id less than or equal to zero (we assume that an Id that is not greater than zero represents a note that is new) and if so, calls the private method saveAsNew . If the Note item sent in has an Id , the code finds that Note in the simulated storage, updates the Title and Description , and returns the Id value. The saveAsNew method sets the Id , adds it to the simulated storage, and returns the Id value. The increment of the Id is simulated here by getting the current count of the note collection and adding 1 to it. The setting of the Id is the only other chunk of code that would be refactored out when moving to a different data storage approach. With our model and data manager code in place we can turn our attention to the controller and views. We can do all of our work in a single controller. If we use a HomeController , we can add an action method named Index that will return our main view. An action method named List will get all of our Note objects from our manager and return a partial view. We will use some jQuery to make an AJAX call to that action method and update our main view with the partial view content returned. Since the jQuery AJAX call will cache the call to the content in Internet Explorer by default (a setting in jQuery), we will decorate the List, Create and Edit action methods with the OutputCache attribute and a duration of 0. This will send the no-cache flag back in the header of the content to the browser and jQuery will pick that up and not cache the AJAX call. The Create action method instantiates a new Note model object and returns a partial view, specifying the NoteForm.cshtml view file and passing in the model. The NoteForm view is used for the add and edit functionality. The Edit action method takes in the Id of the note to be edited, loads the Note model object based on that Id , and does the same return of the partial view as the Create method. The Save method takes in the posted Note object and sends it to the manager to save. It is decorated with the HttpPost attribute to ensure that it will only be available via a POST. It returns a Json object with a property named Success that can be used by the UX to verify everything went well (we won't use that in our example). Both the add and edit actions in the UX will post to the Save action method, allowing us to reduce the amount of unique jQuery we need to write in our view. The contents of the HomeController.cs file: using System . Web . Mvc ; using Website . Models ; namespace Website . Controllers {     public class HomeController : Controller     {         public ActionResult Index ()         {             return View ();         }         [ OutputCache ( Duration = 0 )]         public ActionResult List ()         {             var manager = new NoteManager ();             var model = manager . GetAll ();             return PartialView ( model );         }         [ OutputCache ( Duration = 0 )]         public ActionResult Create ()         {             var model = new Note ();             return PartialView ( "NoteForm" , model );         }         [ OutputCache ( Duration = 0 )]         public ActionResult Edit ( int id )         {             var manager = new NoteManager ();             var model = manager . GetById ( id );             return PartialView ( "NoteForm" , model );         }         [ HttpPost ]         public JsonResult Save ( Note note )         {             var manager = new NoteManager ();             var noteId = manager . Save ( note );             return Json ( new { Success = noteId > 0 });         }     } } The view for the note form, NoteForm.cshtml , looks like so: @model Website . Models . Note @using ( Html . BeginForm ( "Save" , "Home" , FormMethod . Post , new { id = "NoteForm" })) { @Html . Hidden ( "Id" ) < label class = "Title" >     < span > Title < /span><br / >     @Html . TextBox ( "Title" ) < /label> <label class="Body">     <span>Body</ span >< br />     @Html . TextArea ( "Body" ) < /label> } It is a strongly typed view for our Note model class. We give the <form> element an id attribute so that we can reference it via jQuery. The <label> and <span> tags give our UX some structure that we can style with some CSS. The List.cshtml view is used to render out a <ul> element with all of our notes. @model IEnumerable < Website . Models . Note > < ul class = "NotesList" >     @foreach ( var note in Model )     {     < li >         @note . Title < br />         @note . Body < br />         < span class = "EditLink ButtonLink" noteid = "@note.Id" > Edit < /span>     </ li >     } < /ul> This view is strongly typed as well. It includes a <span> tag that we will use as an edit button. We add a custom attribute named noteid to the <span> tag that we can use in our jQuery to identify the Id of the note object we want to edit. The view, Index.cshtml , contains a bit of html block structure and all of our jQuery logic code. @ {     ViewBag . Title = "Index" ; } < h2 > Notes < /h2> <div id="NoteListBlock"></ div > < span class = "AddLink ButtonLink" > Add New Note < /span> <div id="NoteDialog" title="" class="Hidden"></ div > < script type = "text/javascript" >     $ ( function () {         $ ( "#NoteDialog" ). dialog ({             autoOpen : false , width : 400 , height : 330 , modal : true ,             buttons : {                 "Save" : function () {                     $ . post ( "/Home/Save" ,                         $ ( "#NoteForm" ). serialize (),                         function () {                             $ ( "#NoteDialog" ). dialog ( "close" );                             LoadList ();                         });                 },                 Cancel : function () { $ ( this ). dialog ( "close" ); }             }         });         $ ( ".EditLink" ). live ( "click" , function () {             var id = $ ( this ). attr ( "noteid" );             $ ( "#NoteDialog" ). html ( "" )                 . dialog ( "option" , "title" , "Edit Note" )                 . load ( "/Home/Edit/" + id , function () { $ ( "#NoteDialog" ). dialog ( "open" ); });         });         $ ( ".AddLink" ). click ( function () {             $ ( "#NoteDialog" ). html ( "" )                 . dialog ( "option" , "title" , "Add Note" )                 . load ( "/Home/Create" , function () { $ ( "#NoteDialog" ). dialog ( "open" ); });         });         LoadList ();     });     function LoadList () {         $ ( "#NoteListBlock" ). load ( "/Home/List" );     } < /script> The <div> tag with the id attribute of "NoteListBlock" is used as a container target for the load of the partial view content of our List action method. It starts out empty and will get loaded with content via jQuery once the DOM is loaded. The <div> tag with the id attribute of "NoteDialog" is the element for our dialog widget. The jQuery UI library will use the title attribute for the text in the dialog widget top header bar. We start out with it empty here and will dynamically change the text via jQuery based on the request to either add or edit a note. This <div> tag is given a CSS class named "Hidden" that will set the display:none style on the element. Since our call to the jQuery UI method to make the element a dialog widget will occur in the jQuery document ready code block, the end user will see the <div> element rendered in their browser as the page renders and then it will hide after that jQuery call. Adding the display:hidden to the <div> element via CSS will ensure that it is never rendered until the user triggers the request to open the dialog. The jQuery document load block contains the setup for the dialog node, click event bindings for the edit and add links, and a call to a JavaScript function called LoadList that handles the AJAX call to the List action method. The .dialog() method is called on the "NoteDialog" <div> element and the options are set for the dialog widget. The buttons option defines 2 buttons and their click actions. The first is the "Save" button (the text in quotations is used as the text for the button) that will do an AJAX post to our Save action method and send the serialized form data from the note form (targeted with the id attribute "NoteForm"). Upon completion it will close the dialog widget and call the LoadList to update the UX without a redirect. The "Cancel" button simply closes the dialog widget. The .live() method handles binding a function to the "click" event on all elements with the CSS class named EditLink . We use the .live() method because it will catch and bind our function to elements even as the DOM changes. Since we will be constantly changing the note list as we add and edit we want to ensure that the edit links get wired up with click events. The function for the click event on the edit links gets the noteid attribute and stores it in a local variable. Then it clears out the HTML in the dialog element (to ensure a fresh start), calls the .dialog() method and sets the "title" option (this sets the title attribute value), and then calls the .load() AJAX method to hit our Edit action method and inject the returned content into the "NoteDialog" <div> element. Once the .load() method is complete it opens the dialog widget. The click event binding for the add link is similar to the edit, only we don't need to get the id value and we load the Create action method. This binding is done via the .click() method because it will only be bound on the initial load of the page. The add button will always exist. Finally, we toss in some CSS in the Content/Site.css file to style our form and the add/edit links. . ButtonLink { color : Blue ; cursor : pointer ; } . ButtonLink : hover { text - decoration : underline ; } . Hidden { display : none ; } #NoteForm label { display:block; margin-bottom:6px; } #NoteForm label > span { font-weight:bold; } #NoteForm input[type=text] { width:350px; } #NoteForm textarea { width:350px; height:80px; } With all of our code in place we can do an F5 and see our list of notes: If we click on an edit link we will get the dialog widget with the correct note data loaded: And if we click on the add new note link we will get the dialog widget with the empty form: The end result of our solution tree for our sample:

  • Error when Eclipse started and now my package explorer is empty!

    - by carpenteri
    Friends, Just a quick introduction, I'm currently learning Java, using a combination of the Head First Java book and Eclipse. Everything was going well until tonight! When I started up Eclipse tonight, I saw an error message which I didn't pay attention to (I know! I know!) and acknowledged after which the project explorer was empty where it used to contain my Head First project! After a quick "google" I found the workspace.metadata.log and the errors are shown below. The version of Eclipse I am using is: 20100218-1602 and the only plugin that I use is egit. Any help would be much appreciated.

  • Webview crash with Garbage Collector ON

    - by user273666
    Hi, I have a very specific web page that causes webview to crash with the Garnage Collector ON (does not crash when OFF). Easy to reproduce: create a document base application, drop a webview, and have the following line (button perhaps). - (void)connectSearch:(id)sender { [[webView mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://apple.com"]]]; } I guess this scenario is only valid while Apple advertises their new iPad. At the bottom of the page there is two video you can watch. Click on the one on the right. When it is playing, click on the Close button (link) top left - which sends #SwapViewPreviousSelection - and that's it, it crashes. I'm just learning about the garbage collector but I suspect something is collected that should not. Any idea what can prevent the crash, other than turning off the garbage collector? Thank you. Here is what I get: Identifier: com.yourcompany.wb Version: 1.0 (1) Code Type: X86-64 (Native) Parent Process: launchd [163] Date/Time: 2010-02-15 12:26:31.069 -0500 OS Version: Mac OS X 10.6.2

  • Popping UIView crashes app

    - by Adun
    I'm basically pushing a UIView from a UITableViewController and all it contains is a UIWebView. However when I remove the UIView to return back to the UITableView the app crashes. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here. Create and push another view controller. if (indexPath.row == websiteCell) { NSString *urlPath = [NSString stringWithFormat:@"http://%@", exhibitor.website]; WebViewController *webViewController = [[WebViewController alloc] initWithURLString:urlPath]; // Pass the selected object to the new view controller. [self.parentViewController presentModalViewController:webViewController animated:YES]; [webViewController release]; } } If I comment out the [webViewController release] the app doesn't crash, but I know that this would be a leak. Below is the code for the Web Browser: #import "WebViewController.h" @implementation WebViewController @synthesize webBrowserView; @synthesize urlValue; @synthesize toolBar; @synthesize spinner; @synthesize loadUrl; -(id)initWithURLString:(NSString *)urlString { if (self = [super init]) { urlValue = urlString; } return self; } #pragma mark WebView Controls - (void)goBack { [webBrowserView goBack]; } - (void)goForward { [webBrowserView goForward];

  • Trouble passing a template function as an argument to another function in C++

    - by Darel
    Source of the problem -Accelerated C++, problem 8-5 I've written a small program that examines lines of string input, and tallies the number of times a word appears on a given line. The following code accomplishes this: #include <map> #include <iostream> #include <string> #include <vector> #include <list> #include <cctype> #include <iterator> using std::vector; using std::string; using std::cin; using std::cout; using std::endl; using std::getline; using std::istream; using std::string; using std::list; using std::map; using std::isspace; using std::ostream_iterator; using std::allocator; inline void keep_window_open() { cin.clear(); cout << "Please enter EOF to exit\n"; char ch; cin >> ch; return; } template <class Out> void split(const string& s, Out os) { vector<string> ret; typedef string::size_type string_size; string_size i = 0; // invariant: we have processed characters `['original value of `i', `i)' while (i != s.size()) { // ignore leading blanks // invariant: characters in range `['original `i', current `i)' are all spaces while (i != s.size() && isspace(s[i])) ++i; // find end of next word string_size j = i; // invariant: none of the characters in range `['original `j', current `j)' is a space while (j != s.size() && !isspace(s[j])) ++j; // if we found some nonwhitespace characters if (i != j) { // copy from `s' starting at `i' and taking `j' `\-' `i' chars *os++ = (s.substr(i, j - i)); i = j; } } } // find all the lines that refer to each word in the input map<string, vector<int> > xref(istream& in) // works // now try to pass the template function as an argument to function - what do i put for templated type? //map<string, vector<int> > xref(istream& in, void find_words(vector<string, typedef Out) = split) #LINE 1# { string line; int line_number = 0; map<string, vector<int> > ret; // read the next line while (getline(in, line)) { ++line_number; // break the input line into words vector<string> words; // works // #LINE 2# split(line, back_inserter(words)); // #LINE 3# //find_words(line, back_inserter(words)); // #LINE 4# attempting to use find_words as an argument to function // remember that each word occurs on the current line for (vector<string>::const_iterator it = words.begin(); it != words.end(); ++it) ret[*it].push_back(line_number); } return ret; } int main() { cout << endl << "Enter lines of text, followed by EOF (^Z):" << endl; // call `xref' using `split' by default map<string, vector<int> > ret = xref(cin); // write the results for (map<string, vector<int> >::const_iterator it = ret.begin(); it != ret.end(); ++it) { // write the word cout << it->first << " occurs on line(s): "; // followed by one or more line numbers vector<int>::const_iterator line_it = it->second.begin(); cout << *line_it; // write the first line number ++line_it; // write the rest of the line numbers, if any while (line_it != it->second.end()) { cout << ", " << *line_it; ++line_it; } // write a new line to separate each word from the next cout << endl; } keep_window_open(); return 0; } As you can see, the split function is a template function to handle various types of output iterators as desired. My problem comes when I try to generalize the xref function by passing in the templated split function as an argument. I can't seem to get the type correct. So my question is, can you pass a template function to another function as an argument, and if so, do you have to declare all types before passing it? Or can the compiler infer the types from the way the templated function is used in the body? To demonstrate the errors I get, comment out the existing xref function header, and uncomment the alternate header I'm trying to get working (just below the following commment line.) Also comment the lines tagged LINE 2 and LINE 3 and uncomment LINE 4, which is attempting to use the argument find_words (which defaults to split.) Thanks for any feedback!

  • fatal error C1084: Cannot read type library file: 'Smegui.tlb': Error loading type library/DLL.

    - by Steiny
    Hi, I am trying to build an old version of an application which consists of VC++ projects that were written in Visual Studio 2003. My OS is Windows 7 Enterprise (64-bit). When I try and build the solution I get the following errors: error C4772: #import referenced a type from a missing type library; '__missing_type__' used as a placeholder fatal error C1084: Cannot read type library file: 'Smegui.tlb': Error loading type library/DLL. They both complain about the following import statement: #import "Smegui.tlb" no_implementation This is not a case of the file path being incorrect as renaming the Smegui.tlb file causes the compiler to throw another error saying it cannot find the library. Smegui is from another application that this one depends on. I thought perhaps I was missing a dll but there is no such thing as Smegui.dll. All I know about .tlb files is that they are a type library and you can create them from an assembly using tlbexp.exe or regasm.exe (the later also registers the assembly with COM) There is also an Apache Ant build script which uses a custom task to invoke devenv.com to build the projects. This is the same script that the build server originally used to build the application. It gives me the same errors when I try and run it. The strangest thing about this is that I knew it ought to work seeing as it is all freshly checked out from subversion. I tried many different combinations of admin vs user elevation, VS vs Ant build, cleaning, release. I have got it to build successfully about 5 times but the build seems to be non-deterministic. If anyone can shed some light on how this tlb stuff even works or what this error might mean I would greatly appreciate it. Cheers, Steiny
