  • Noob Objective-C/C++ - Linker Problem/Method Signature Problem

    - by Josh
    There is a static class Pipe, defined in C++ header that I'm including. The static method I'm interested in calling (from Objetive-c) is here: static ERC SendUserGet(const UserId &_idUser,const GUID &_idStyle,const ZoneId &_idZone,const char *_pszMsg); I have access to an objetive-c data structure that appears to store a copy of userID, and zoneID -- it looks like: @interface DataBlock : NSObject { GUID userID; GUID zoneID; } Looked up the GUID def, and its a struct with a bunch of overloaded operators for equality. UserId and ZoneId from the first function signature are #typedef GUID Now when I try to call the method, no matter how I cast it (const UserId), (UserId), etc, I get the following linker error: Ld build/Debug/Seeker.app/Contents/MacOS/Seeker normal i386 cd /Users/josh/Development/project/Mac/Seeker setenv MACOSX_DEPLOYMENT_TARGET 10.5 /Developer/usr/bin/g++-4.2 -arch i386 -isysroot /Developer/SDKs/MacOSX10.5.sdk -L/Users/josh/Development/TS/Mac/Seeker/build/Debug -L/Users/josh/Development/TS/Mac/Seeker/../../../debug -L/Developer/Platforms/iPhoneOS.platform/Developer/usr/lib/gcc/i686-apple-darwin10/4.2.1 -F/Users/josh/Development/TS/Mac/Seeker/build/Debug -filelist /Users/josh/Development/TS/Mac/Seeker/build/Seeker.build/Debug/Seeker.build/Objects-normal/i386/Seeker.LinkFileList -mmacosx-version-min=10.5 -framework Cocoa -framework WebKit -lSAPI -lSPL -o /Users/josh/Development/TS/Mac/Seeker/build/Debug/Seeker.app/Contents/MacOS/Seeker Undefined symbols: "SocPipe::SendUserGet(_GUID const&, _GUID const&, _GUID const&, char const*)", referenced from: -[PeoplePaneController clickGet:] in PeoplePaneController.o ld: symbol(s) not found collect2: ld returned 1 exit status Is this a type/function signature error, or truly some sort of linker error?

  • Where can I find this hotfix?

    - by speeder
    I've got a problem, and seemly the solution is a hot fix mentioned here. The problem is that the link there pointing to location of the hotfix is broken, leading to a search page on MS site. And looking around I figured that the easiest way is to phone Microsoft, but I live in other country. So, how I fix the problem described in the KB page that I linked? EDIT: Extra note: I DO have the SP3... :(

  • "Fuzzy" Display Problems on New OpenSUSE 11.3 Install

    - by Kryten
    Hi, I have a old Desktop that has a new installation of OpenSUSE 11.3 on it. To get straight to the point, whenever I try to start-up OpenSUSE, my display goes "fuzzy" (almost like a badly tuned TV) and sometimes (not always) my monitor goes black and says "Out of Range: 15.6kHz/49Hz": I assumed that this was a driver problem, so I download the drivers from nvidia and ran the shell script, completed and rebooted. Then OpenSUSE failed to boot with something like "nscd failed to start". At that point I decided to re-install and I did, but this time I tried un-checking "Automatic Configuration" to see if that helped. Got through the install and still have a problem. Unfortunately, my Linux troubleshooting skills are non-existent, so has anyone got any ideas on what could be the problem (is it the display driver?) and how I can fix the problem?

  • Master File Table Corrupt, any way to save data?

    - by domen
    hi. I've used search, but none of the results match my problem so I didn't have to ask separate question. I've Installed Windows 7 RTM recently and since then partitions located on one of my HDDs have gone "crazy". They used to "freeze" and didn't open in explorer for some time (minute or two, usually), sometimes all partitions of the drive wouldn't show until reboot and finally, one of those partitions started showing "disk structure is corrupted and unreadable" warning, it appeared in Disk Management window as RAW and chkdsk showed "mft corrupt". There were no important data on the partition and I didn't have enough time to analyze the problem at the moment, so I just reformatted it and ran antivirus scan on system. After that problem settled for some time, but yesterday the problematic HDD vanished again from the system. After reboot chkdsk identified mft of four partitions corrupt and now they are all in same conditions as the above mentioned one. But the difference is that the files stored in them are extremely important. and just for info: I upgraded from Win7 build 7077, but had some performance issues, so I reformatted system drive and installed fresh Win7 RTM on it. I've downloaded TestDisk and it shows all the partitions marked as NTFS (not RAW) and my knowledge of the program wasn't sufficient to obtain any other info from it :-) and the images that could help describe the problem (sorry, I'm not allowed to post images and more than one hyperlink): http:// img22.imageshack.us/img22/5909/chkdskz.jpg http:// img198.imageshack.us/img198/5576/computeray.jpg I'm interested, is there a way to let me restore the MFT or just access files so I can backup them before reformatting the drive. Thanks for your time. :) P.S. my reformatted drive is showing no problems, could there be a problem with windows 7 itself? I googled, but with no results.

  • Please quickly help with this problem I got 52 minutes left.

    - by Hamish Grubijan
    Write a program that prints the numbers from 1 to 100. But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz". Woman said use any common language. Please make it short and test it. My screen is small. Thanks. P.S. I have test anxiety particularly after talking to people in suits. I also stayed up all night studying Java codes.

  • Xp SP3 - Non-Functioning

    - by Josh
    Ok Here is a crazy problem, I have a HP dv6000 Laptop that can no longer hold a charge, so I hooked it up to my TV, bought a wireless mouse and keyboard and configured xp to run with the lid closed, It has medium to heavy usage mainly just streaming from sites like Netfilx, Hulu, ABC, etc. And playing movies I ripped of dvd. It ran fine for a while but recently it has been having some weird problems: Problem one: I used to use firefox but now when run it I can type but as soon as I click something it just shuts down, completely, I can't even close it unless I use taskmanager to do it. So I went and got google chrome which is better but still hit or miss, but never completely shuts down, I just can't click anything or type anything, or sometimes I just can't type anything or vice versa. Also when I open a new tab, and try to move back to my old one, it automatically closes the old tab when I click on it. Problem two: When using the internet I can't use any other application or anything windows (ie. Windows explorer) until I force quit all browsers with taskmanger. The reason I can't run anything is because I can't click on it. Problem three: When I try to play a movie (with vlc) Once it starts playing I can't click on anything, but I can use hotkeys, and once it stops everything is fine again. Well I hope somebody knows whats going on because I have no clue, If you need clarification or more info on something I would be happy to provide it...

  • Come up with a real-world problem in which only the best solution will do (a problem from Introduction to algorithms) [closed]

    - by Mike
    EDITED (I realized that the question certainly needs a context) The problem 1.1-5 in the book of Thomas Cormen et al Introduction to algorithms is: "Come up with a real-world problem in which only the best solution will do. Then come up with one in which a solution that is “approximately” the best is good enough." I'm interested in its first statement. And (from my understanding) it is asked to name a real-world problem where only the exact solution will work as opposed to a real-world problem where good-enough solution will be ok. So what is the difference between the exact and good enough solution. Consider some physics problem for example the simulation of the fulid flow in the permeable medium. To make this simulation happen some simplyfing assumptions have to be made when deriving a mathematical model. Otherwise the model becomes at least complex and unsolvable. Virtually any particle in the universe has its influence on the fluid flow. But not all particles are equal. Those that form the permeable medium are much more influental than the ones located light years away. Then when the mathematical model needs to be solved an exact solution can rarely be found unless the mathematical model is simple enough (wich probably means the model isn't close to reality). We take an approximate numerical method and after hours of coding and days of verification come up with the program or algorithm which is a solution. And if the model and an algorithm give results close to a real problem by some degree that is good enough soultion. Its worth noting the difference between exact solution algorithm and exact computation result. When considering real-world problems and real-world computation machines I believe all physical problems solutions where any calculations are taken can not be exact because universal physical constants are represented approximately in the computer. Any numbers are represented with the limited precision, at least limited by amount of memory available to computing machine. I can imagine plenty of problems where good-enough, good to some degree solution will work, like train scheduling, automated trading, satellite orbit calculation, health care expert systems. In that cases exact solutions can't be derived due to constraints on computation time, limitations in computer memory or due to the nature of problems. I googled this question and like what this guy suggests: there're kinds of mathematical problems that need exact solutions (little note here: because the question is taken from the book "Introduction to algorithms" the term "solution" means an algorithm or a program, which in this case gives exact answer on each input). But that's probably more of theoretical interest. So I would like to narrow down the question to: What are the real-world practical problems where only the best (exact) solution algorithm or program will do (but not the good-enough solution)? There are problems like breaking of cryptographic ciphers where only exact solution matters in practice and again in practice the process of deciphering without knowing a secret should take reasonable amount of time. Returning to the original question this is the problem where good-enough (fast-enough) solution will do there's no practical need in instant crack though it's desired. So the quality of "best" can be understood in any sense: exact, fastest, requiring least memory, having minimal possible network traffic etc. And still I want this question to be theoretical if possible. In a sense that there may be example of computer X that has limited resource R of amount Y where the best solution to problem P is the one that takes not more than available Y for inputs of size N*Y. But that's the problem of finding solution for P on computer X which is... well, good enough. My final thought that we live in a world where it is required from programming solutions to practical purposes to be good enough. In rare cases really very very good but still not the best ones. Isn't it? :) If it's not can you provide an example? Or can you name any such unsolved problem of practical interest?

  • LAN connection loses network access randomly

    - by bill11
    Hi, Windows 7 is a great OS but there are some problems which should be solved from Microsoft as fast as possible. On my Computer the LAN connection randomly loses its connection. I don't know why but I think this problem depends on my network driver which is only available for Windows XP (where it always worked perfectly). I can not reproduce this issue. Has anybody here had the same problem?

  • I have a performance problem

    - by Alan
    (copied from my wordpress blog). So start 95% of the performance calls that I receive. They usually continue something like: I have gathered some *stat data for you (eg the guds tool from Document 1285485.1), can you please root cause our problem? So, do you think you could? Neither can I, based on this my answer inevitably has to be "No". Given this kind of problem statement, I have no idea about the expectations, the boundary conditions, or even the application. The answer may as well be "Performance problems? Consult your local Doctor for Viagra". It's really not a lot to go on. So, What kind of problem description is going to allow me to start work on the issue that is being seen? I don't doubt that there really is an issue, it just needs to be pinned down somewhat. What behavior exactly are you expecting to see? Be specific and use business metrics. For example "run-time", "response-time" and "throughput". This helps us define exit criterea. Now, let's look at the system that is having problems. How is what you are seeing different? Use the same type of metrics. The answers to these two questions take us a long way towards being able to work a call. Even more helpful are answers to questions like Has this system ever worked to expectation? If so, when did it start exhibiting this behavior? Is the problem always present, or does it sometimes work to expectation? If it sometimes works to expectation, when are you seeing the problem? Is there any discernible pattern? Is the impact of the problem getting better, worse, or remaining constant? What kind of differences are there between when the system was performing to expectation and when it is not? Are there other machines where we could expect to see the same issue (eg similar usage and load), but are not? Again, differences? Once we start to gather information like this we start to build up a much clearer picture of exactly what we need to investigate, and what we need to achieve so that both you and me agree that the problem has been solved. Please help get that figure of poorly defined problem statements down from it's current 95% value.

  • File Acces\Rename Issue

    - by Moon .
    Guys, i am having serious problem with media files (only video files). When i try to rename or delete a Files or the Folders that contained media files, i get an error. "Access Denied .... Some other program might be using this file..... bla bla bla" Previously for this knida problem i had a freeware "Unlocker" that used to work. What "Unlocker" used to do was simply kill the process that is using the file. But in my case, now that is, the process using the files is "Explorer.exe" W.T.F... A strange behavior, when i copy paste the same file. The copied file, I can rename it, i can delete it, i can shit on it if i want to.... but what is wrong with the original file. Check the following list. It will give you a better idea of my situation. I am using Win XP SP 2 I have got Div Player installed (latest) The media files are from both, my hard drive, created by many of my previous window installations. And new downloaded files. So Files ownership or Privacy is not an issue. I may not be able to rename\delete those files one moment, the next moment, in the next try, i might succeed. The problem is a major F. i can't figure it out. Please F1! its getting on my nerves.

  • Problem upgrading from 13.04 to 13.10

    - by Charles
    Part way through upgrading from 13.04 to 13.10 the process ground to a halt with an error message. Now on retrying by going to 'Check for updates' I get the following: Failed to load the package list This is a serious problem. Try again later. If this problem appears again, please report an error to the developers. E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_saucy_universe_i18n_Translation-en%%5fGB, E:The package lists or status file could not be parsed or opened. Problem reported but my question is, "what can I do now?; Do I have to do a fresh install?; if so will settings etc. in my Home folder (on its own partition) be saved?" 13.04 still seems to be working perfectly, while upgrading I had a terrible internet connection varying between 'dead slow' and 'dead stop', not sure if that caused the problem.

Actually problems starts last night when my desktop wallpaper changes suddenly to Ubuntu default, when I tried to change wallpaper I find that my right click is not working. I tried to reboot system but that also not solved my problem,i clicked here and there but when I opened the home folder my wallpaper changed again to previous one and when I checked the right click it is also working. Now the problem is that this problem comes back again whenever I turn on my system,and also whenever this problem occurs the Ubuntu desktop menu bar also disappears from unity top panel. Don't know what is really going on, please can anybody help me.

  • HP Printer scrolls "printing" forever - but nothing happens

    - by brett80
    I got a used HP Officejet 7130 all-in-one printer. I tried printing a text document, and it shows up in the queue (and says "printing"), and the printer display says "Printing" "Press Cancel to cancel job." - and it cyles that text forever, but nothing ever happens (after a couple of initial quiet noises.) I tried to print a test page from the printer, and I get the same "printing" message. I checked the hp website, and this problem is not on their list. (They are expecting a queue problem, error message, etc.) I did initially get a message that it needs new ink cartridges, but I pressed to get past that. It's supposed to try to print anyway. I don't want to buy ink cartridges for a printer that is broken. When I press it cancels correctly.

  • Cannot access a web page?

    - by ipkiss
    Hello all, Recently, I could not access the webpage bbc.co.uk anymore, while I can access other websites smoothly. Ar first, I though there may be some problem with my laptop. However, if I use my laptop through my company network, I can load the page bbc.co.uk normally. Then, I though maybe my ADSL at home blocks that web address. However, I tried another laptop with my home ADSL and it can load the page bbc.co.uk very fast. Now I do not know what could be the problem. Can anyone tell me please? Thank you.

  • remote desktop over wireless

    - by tbischel
    So I'm trying to run remote desktop on my laptop to connect to my home desktop. I have a problem where this works fine if I connect my laptop with an ethernet cable, but fails when I try to use wireless internet access (which works fine for normal internet surfing). I've experienced this problem at home with my wireless router, and at work with the wireless network they have there, so I'm inclined to believe that its a setting local to my machine rather than the router blocking the requests... but I'm not sure where to look. Any suggestions?

  • Computer Flashes Out?

    - by GuyNoir
    We have a strange problem with our computers at my school. They are all Latitude 2100 Netbooks. At random points (I can't seem to find a pattern) the screen will turn a single color (red, green, black, brown, etc.) To fix this, the computer must be put to sleep, and brought back up. They have integrated graphics, but I can't imagine that if it was a bug with the computer itself, that every single computer would do this. Is there any way I could find out the problem that's causing this. Some diagnostic tool? Thanks. Edit: Forgot, they all have windows.

  • What could explain my partitions disappearing on a new SSD with Windows 7?

    - by charlesrandall
    So this morning, I had a fresh install of Windows 7 pro, on a new SSD (Patriot TorqX 128gb), which I just put in to a new Dell Studio XPS 9000. Everything was fine. I booted to windows, no problem. I go to work. 8 hours later, I come home, and I'm greeted by my boot screen complaining about no bootable devices. Windows repair from the Windows 7 pro disk says it can't fix the problem. It doesn't see any windows installs. I boot up GParted, and my SSD is completely unallocated. No space used, no partitions. Perhaps this is related to allowing windows 7 to create a utility partition when I installed? Only thing I can think of. Is there some kind of known hardware issue that can result in an SSD completely wiping itself?

  • win7: app crashing/hanging on "save as"-dialog

    - by Fuxi
    hi all, now this is really annoying - i'm having a global problem in win7: when using the system's "save as"-filedialog, the main app will just hang. the mouse-cursor is showing progress, the whole app is hanging and i need to terminate it manually. it's happening with every app! (notepad, word, graphics app). i'm assuming it's something with the system enumerating the harddisk-drivenames or something. any idea how to fix this? btw - when viewing the problem details - it's telling the module - it's msonsext.dll looks like some office thing to me. thanks

  • Ambiguous in the namespace problem

    - by Agha Usman Ahmed
    From the last few days, I was ignoring an error that keep coming at the compile time. I spent some two hours on it before but didn’t get it work. The error is quit confusing and of course difficult to manage. 'ApplicationSettingsBase' is ambiguous in the namespace 'System.Configuration' 'MailMessage' is ambiguous in the namespace 'System.Net.Mail' And there are couple of other similar errors that is pointing to some ambiguous references in my project.  The confusing part is that the MailMessage object throws similar error when you are importing the old and new email namespace. For example, Imports System.Web.Mail Imports System.Net.Mail So if you are only encountering ambiguous problem in MailMessage object. It is more possible that you have define both the namespaces in your code behind which is actually confusing the compiler about your referencing object. The quick solve for this problem is that remove Imports System.Web.Mail and it should work smooth. But with me, I never used the old asp.net mail namespace in my project. Then I start looking at my references and luckily I found the problem there. Follow the steps below to investigate the issue 1. Go to your project 2. Then references 3. Right click on “System” and see properties. it should point to the following path x:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll Where x is name of your operating system directory. This was the problem with my project. I had my operating system install on “D” drive and some how it is pointing to “C” drive which is the root cause of this problem. After that I verify all my references and found 5 –6 assemblies that are pointing to wrong path and get it worked. Also note, the problem can occur in any type of project either it is website , web application etc.

  • windows Home Server backup error

    - by domen
    I've finally built my WHS, but some other problems have showed up. I've googled, binged and searched SU with no success. The problem is following: at the moment I've got a Win7 laptop and Win7 PC, which should be backed up by the WHS. Laptop is backed up just fine with no issues, but when I try to manually backup the PC, after "backup is starting" message, when backup service should be monitoring changes on partitions, PC gets disconnected from the home network and thus, the backup process is stuck. Disabling/enabling network adapter gets PC back on the network. The only thing I've tried was reinstalling connector software. no success. Also, I've downloaded connector troubleshooter and only thing it says is "DHCP server was not found". I'm not good with networks, so I couldn't figure out what could that indicate (all computers in the network are assigned static IPs). Any ideas what the problem can be? I can provide any additional information, I'm just not sure what may be helpful right now. Thanks.
