  • C++ keeping a list of objects and calling a contructor through another function

    - by Nona Urbiz
    why isnt my object being created? When I do it like so, I am told error C2065: 'AllReferrals' : undeclared identifier as well as error C2228: left of '.push_back' must have class/struct/union. If I put the list initialization before the class I get error C2065: 'AllReferrals' : undeclared identifier. Thanks! #include <iostream> #include <fstream> #include <regex> #include <string> #include <list> #include <map> using namespace std; using namespace tr1; class Referral { public: string url; map<string, int> keywords; static bool submit(string url, string keyword, int occurrences) { //if(lots of things i'll later add){ Referral(url, keyword, occurrences); return true; //} //else // return false; } private: list<string> urls; Referral(string url, string keyword, int occurrences) { url = url; keywords[keyword] = occurrences; AllReferrals.push_back(this); } }; static list<Referral> AllReferrals; int main() { Referral::submit("url", "keyword", 1); cout << AllReferrals.size(); cout << "\n why does that ^^ say 0 (help me make it say one)?"; cout << "\n and how can i AllReferrals.push_back(this) from my constructor?"; cout << " When I do it like so, I am told error C2065: 'AllReferrals' : undeclared identifier"; cout << " as well as error C2228: left of '.push_back' must have class/struct/union."; cout << " If I put the list initialization before the class I get error C2065: 'AllReferrals' : undeclared identifier."; cout << "\n\n\t Thanks!"; getchar(); }

  • How to write a cctor and op= for a factory class with ptr to abstract member field?

    - by Kache4
    I'm extracting files from zip and rar archives into raw buffers. I created the following to wrap minizip and unrarlib: Archive.hpp #include "ArchiveBase.hpp" #include "ArchiveDerived.hpp" class Archive { public: Archive(string path) { /* logic here to determine type */ switch(type) { case RAR: archive_ = new ArchiveRar(path); break; case ZIP: archive_ = new ArchiveZip(path); break; case UNKNOWN_ARCHIVE: throw; break; } } Archive(Archive& other) { archive_ = // how do I copy an abstract class? } ~Archive() { delete archive_; } void passThrough(ArchiveBase::Data& data) { archive_->passThrough(data); } Archive& operator = (Archive& other) { if (this == &other) return *this; ArchiveBase* newArchive = // can't instantiate.... delete archive_; archive_ = newArchive; return *this; } private: ArchiveBase* archive_; } ArchiveBase.hpp class ArchiveBase { public: // Is there any way to put this struct in Archive instead, // so that outside classes instantiating one could use // Archive::Data instead of ArchiveBase::Data? struct Data { int field; }; virtual void passThrough(Data& data) = 0; /* more methods */ } ArchiveDerived.hpp "Derived" being "Zip" or "Rar" #include "ArchiveBase.hpp" class ArchiveDerived : public ArchiveBase { public: ArchiveDerived(string path); void passThrough(ArchiveBase::Data& data); private: /* fields needed by minizip/unrarlib */ // example zip: unzFile zipFile_; // example rar: RARHANDLE rarFile_; } ArchiveDerived.cpp #include "ArchiveDerived.hpp" ArchiveDerived::ArchiveDerived(string path) { //implement } ArchiveDerived::passThrough(ArchiveBase::Data& data) { //implement } Somebody had suggested I use this design so that I could do: Archive archiveFile(pathToZipOrRar); archiveFile.passThrough(extractParams); // yay polymorphism! How do I write a cctor for Archive? What about op= for Archive? What can I do about "renaming" ArchiveBase::Data to Archive::Data? (Both minizip and unrarlib use such structs for input and output. Data is generic for Zip & Rar and later is used to create the respective library's struct.)

  • Block copy PDF document

    - by Wiliam Witter
    hello Gentlemen, I would like block copy (ctrl+c ctrl+v) PDF document using java. I have a code that build a PDF document with JasperReport... //seta o caminho dos arquivos jasper String pathLote = ScopeSupport.getServletContext().getRealPath("priv/sgc/relatorios/AtaPregaoLotePageReport.jasper"); String pathCabecalho = ScopeSupport.getServletContext().getRealPath("priv/sgc/relatorios/CabecalhoPageReport.jasper"); String pathRodape = ScopeSupport.getServletContext().getRealPath("priv/sgc/relatorios/rodapePageReport.jasper"); String imagemDir = ScopeSupport.getServletContext().getRealPath("/priv/comum/img"); //HashMap parametros passa o parametro usado na query e o caminho da imagem HashMap<String,Object> parametros = new HashMap<String,Object>(); parametros.put("idPregao", idPregao); parametros.put("idLote", idLote); parametros.put("IMAGEM_DIR", imagemDir + "/"); parametros.put("USUARIO", "NomeUsuario" ); parametros.put("texto", texto); parametros.put("numeroAta", numAta); if(numAta != null && numAta > 0) parametros.put("relatorio", "Ata "+numAta); HashMap<String,Object> parametrosSub = new HashMap<String,Object>(); parametrosSub.put("CabecalhoPageReport", pathCabecalho); parametrosSub.put("rodapePageReport", pathRodape); parametrosSub.put("AtaPregaoPorLotePageReport", pathLote); for(String element : parametrosSub.keySet()){ parametros.put(element, (JasperReport) JRLoader.loadObject((String) (parametrosSub.get(element)))); } JasperReport report = (JasperReport) JRLoader.loadObject( pathLote ); JasperPrint printRel = JasperFillManager.fillReport( report, parametros, getJDBCConnection() ); byte[] bytes = JasperExportManager.exportReportToPdf(printRel); httpResponse.setHeader("Content-Disposition","attachment; filename=\""+ report.getName() + ".pdf" +"\";"); httpResponse.setContentLength(bytes.length); httpResponse.setContentType("application/pdf"); ServletOutputStream ouputStream = httpResponse.getOutputStream(); ouputStream.write(bytes, 0, bytes.length); ouputStream.flush(); ouputStream.close(); Who can help me with this?

  • How to copy the memeory allocated in device function back to main memory

    - by xhe8
    I have a CUDA program containing a host function and a device function Execute(). In the host function, I allocate a global memory output which will then be passed to the device function and used to store the address of the global memory allocated within the device function. I want to access the in-kernel allocated memory in the host function. The following is the code: #include <stdio.h> typedef struct { int * p; int num; } Structure_A; \__global__ void Execute(Structure_A *output); int main(){ Structure_A *output; cudaMalloc((void***)&output,sizeof(Structure_A)*1); dim3 dimBlockExecute(1,1); dim3 dimGridExecute(1,1); Execute<<<dimGridExecute,dimBlockExecute>>>(output); Structure_A * output_cpu; int * p_cpu; cudaError_t err; output_cpu= (Structure_A*)malloc(1); err=cudaMemcpy(output_cpu,output,sizeof(Structure_A),cudaMemcpyDeviceToHost); if( err != cudaSuccess) { printf("CUDA error a: %s\n", cudaGetErrorString(err)); exit(-1); } p_cpu=(int *)malloc(1); err=cudaMemcpy(p_cpu,output_cpu[0].p,sizeof(int),cudaMemcpyDeviceToHost); if( err != cudaSuccess) { printf("CUDA error b: %s\n", cudaGetErrorString(err)); exit(-1); } printf("output=(%d,%d)\n",output_cpu[0].num,p_cpu[0]); return 0; } \__global__ void Execute(Structure_A *output){ int thid=threadIdx.x; output[thid].p= (int*)malloc(thid+1); output[thid].num=(thid+1); output[thid].p[0]=5; } I can compile the program. But when I run it, I got a error showing that there is a invalid argument in the following memory copy function. "err=cudaMemcpy(p_cpu,output_cpu[0].p,sizeof(int),cudaMemcpyDeviceToHost);" CUDA version is 4.2. CUDA card: Tesla C2075 OS: x86_64 GNU/Linux

  • How to copy_if from map to vector?

    - by VJo
    I'd like to copy values that match a predicate (equal ints) from a map<string,int> to a vector<int>. This is what I tried: #include <map> #include <vector> #include <algorithm> int main() { std::vector< int > v; std::map< std::string, int > m; m[ "1" ] = 1; m[ "2" ] = 2; m[ "3" ] = 3; m[ "4" ] = 4; m[ "5" ] = 5; std::copy_if( m.begin(), m.end(), v.begin(), [] ( const std::pair< std::string,int > &it ) { return ( 0 == ( it.second % 2 ) ); } ); } The error message from g++ 4.6.1 is : error: cannot convert 'std::pair<const std::basic_string<char>, int>' to 'int' in assignment Is there a way to adjust the example to do the above copy?

  • Move and rename file in android

    - by Andre Fróes
    I am trying to copy a file to another folder in the android, but so far, i got no success. I manage to do so with a selected image and when taking a photo, but not with files. I've read and tried several solutions passed by the community (searched over the forum and the internet), but none of it was able to solve my problem when copying. First things first. I added the permissions to my manifest: <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> after that, before copying a file, i print its filepath and the directory file path: 06-10 11:11:11.700: I/System.out(1442): /mimetype/storage/sdcard/Misc/Javascript erros for Submit and Plan buttons in IE.doc 06-10 11:11:11.710: I/System.out(1442): /storage/sdcard/mywfm/checklist-files both exists: to copy the file to the expected folder I used the FileUtils: try { FileUtils.copyFile(selectedFile, dir); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } The problem is: I get no exception and the file isn't there. I tried this solution either: How to move/rename file from internal app storage to external storage on Android? same thing, no exception, but no file either.

  • virtual directory make file copy operation extremely slow on UNC Path (IIS 7.5 bug?)

    - by user144737
    When i create a website/virtual directory pointing to UNC path, its make our file copy extremely slow on the UNC path. 6 seconds for file copy (~13 M) on the UNC path without any virtual directory/website pointing to it. over 1 mins. for file copy (same files ~13M) on the same UNC path with virtual directory/website pointing to it. All file copy operation run on web server side. Our setting as below: Web server - Windows Server standard R2 2008 / IIS 7.5 File server - Windows Server standard 2003 I have tested this case on 3 servers (Windows Server standard R2 2008 / IIS 7.5) and got same result. I also tested this case on 2 windows 2003 / IIS 6, it won't slow down the file copy. Is it IIS 7.5 bug? any patch/hotfix to solve this case? Thank you. Gordon

  • Files missing after copying from one sdcard to another using Ubuntu 12.04

    - by Abhi Kandoi
    I have two Kingston sdcards 8GB and 32GB. The 8GB for HTC Sensation and 32GB for my Tablet (Chinese). I soon ran out of space on my phone and decided to swap the data between the sdcards. I copied the data of 32GB sdcard to my PC(with Ubuntu 12.04) deleted everything on the 32GB sdcard and copied data from the 8GB sdcard to the other sdcard. At last I copied the data from my PC to the 8GB sdcard(before this I deleted everything that was on it before). Now the problem is that the 8GB sdcard has the data exactly the same, but the 32GB sdcard has some missing data. All my photos(not copied or posted on Facebook) and Songs are lost. Please help as to what I can do to get my data back? I have Android Revolution HD (ICS 4.0.3) on my rooted HTC Sensation (India). I suspect it has something to do with my data loss.

  • How do I hide "Extra File" and "100%" lines from robocopy output?

    - by Danny Tuppeny
    I have a robocopy script to back up our Kiln repositories that runs nightly, which looks something like this: robocopy "$liveRepoLocation" "$cloneRepoLocation" /MIR /MT /W:3 /R:100 /LOG:"$backupLogLocation\BackupKiln.txt" /NFL /NDL /NP In the output, there are a ton of lines that contain "Extra file"s, like this: *EXTRA File 153 E:\Kiln Backup\elasticsearch\data\elasticsearch-kiln\nodes\0\indices\kiln-2\0\index\_yxe.fdt *EXTRA File 12 E:\Kiln Backup\elasticsearch\data\elasticsearch-kiln\nodes\0\indices\kiln-2\0\index\_yxe.fdx *EXTRA File 128 E:\Kiln Backup\elasticsearch\data\elasticsearch-kiln\nodes\0\indices\kiln-2\0\index\_yxe.fnm *EXTRA File 363 E:\Kiln Backup\elasticsearch\data\elasticsearch-kiln\nodes\0\indices\kiln-2\0\index\_yxe.frq *EXTRA File 13 E:\Kiln Backup\elasticsearch\data\elasticsearch-kiln\nodes\0\indices\kiln-2\0\index\_yxe.nrm Additionally, there are then hundreds of lines at the bottom that contain nothing but "100%"s, like this: 100% 100% 100% 100% 100% 100% 100% In addition to making the log files enormous (there are a lot of folders/files in Kiln repos), it makes it annoying to scan through the logs now and then to see if everything was working ok. How do I stop "Extra Files" appearing in the log? How do I stop these silly "100%" lines appearing in the log? I've tried every combination of switch I can think of (the current switches are listed above in the command), but neither seem to hide these!

  • Software distribution from web server to client using PHP/FTP

    - by Jenolan
    I develop and maintain a number of add-ons and utilities for various widget (mainly aMember) which generally means I need to install php based codes onto other people's systems. Whilst I have a VPS and have access to rsync and all sorts of yummy tools most of the people I deal with have a basic ftp access and that's all folks. To upload from my local system is also a problem as I am satellite based (two-way) so it is fairly slow and expensive and in any case the files are already on my server. So there is no rsync, fxp, ssh and I can't really install anything as it is obviously not my system, they would be justifiably miffed if I started installing file managers or other things onto their sites. What I have been trying to find is a utility that I can run on my server from the web, preferably php based, that will be like a file manager but a bit different. Two panels. LH-Side the local server .. pretty much like a standard FM application RH-Side ability to login via FTP to the clients system Then I can fiddle as required. The closest thing I have found is net2ftp but it doesn't have the gui interface, at the moment I simply ssh into my server power up ncftp and run that way, but something easier to use would be mucho niceness. Thanks in advance! Larry

  • VSS Not Creating Shadow Set

    - by Jeff Leyser
    I'm trying to setup backup scripts on WinXP to use Volume Shadow Sets. I downloaded the VSS 7.2 SDK from MSFT, and used the include vshadow.exe to create a shadow set: vshadow -script=vss-setvar.cmd f: (note that I've tried both f: and c:) vshadow executes just find, giving no errors, reporting the shadow is created. However, executing vshadow -q as the very next command results in "There are no shadows on the system" and, indeed, if I use dosdev to try and map the Shadow set named in vss-setvar.cmd, it will not work. Am I missing a step?

  • linux to linux, 10TB transfer?

    - by lostincode
    I've looked at all the previous similar questions, but the answers seemed to be all over the place and no one was moving a lot of data (100GB != 10TB). I've got about 10TB that I need to move from one raid to another, gigabit net, XFS file systems. My biggest concern is having the transfer die midway and not being able to resume easily. Speed would be nice, but ensuring transfer is much more important. Normally I'd just tar & netcat, but the raid I'm moving from has been super flaky as of late and I need to be able to recover and resume if it drops mid process. Should I be looking at rsync?

  • Virtual Server 2005 VSS writer missing

    - by Jon S.
    I have two servers running Virtual server 2005 R2 SP1. I'm using Symantec Backup Exec 10d for backups. One server runs the backups fine but the other will cause the vm's to crash when it tries to backup. I think the problem is because the "Microsoft Vitual Server 2005 Writer" is not showing up when I run "vssadmin list writers". Can I install the writer without reinstalling VS 2005?

  • Does DFSR replicate shadow copies?

    - by Jeff Sacksteder
    There a a few questions related to using DFSR and Shadow Copies together, but none that indicates if Shadow Copies replicate or not. Meaning, if I have a a pair of DFS replicas with Shadow Copies on Server-A, can I revert that file to a previous version on Server-B? If so, will that reversion be replicated back to Server-A? I suspect not- that VSS is a local NTFS feature and outside the scope of replication, but I cannot verify that myself at the moment.

  • I disconnected my cellphone while transferring files to its Mini SD card. Now the files aren't there

    - by Martín Fixman
    I use Ubuntu 9.10, and the MiniSD card shows as having the space used as if there were files. Baobab (the disk usage analyzer) shows that the card only has 118 MB used (of the 401 Ubuntu claims there are). Of course, I already tried the obvious (rebooting the phone, adding and removing files, etc.), but I don't want to format my card, because I still have some files on it, the transfer to my computer is slow, and because I use an old wire it fails often.

  • Hell: NTFS "Restore previous versions"...

    - by ttsiodras
    The hell I have experienced these last 24h: Windows 7 installation hosed after bluetooth driver install. Attempting to recover using restore points via "Repair" on the bootable Win7 installation CD. Attempting to go back one day in the restore points. No joy. Attempting to go back two days in the restore points. No joy. Attempting to go back one week in the restore points. Stil no joy. Windows won't boot. Apparently something is REALLY hosed. And then it hits me - PANIC - the restore points somehow reverted DATA files to their older versions! Word, Powerpoint, SPSS, etc document versions are all one week old now. Using the "freshest" restore point. Failed to restore yesterday's restore point!!! I am stuck at old versions of the data!!! Booting KNOPPIX, mounting NTFS partition as read-only under KNOPPIX. Checking. Nope, the data files are still the one week old versions. Booting Win7 CD, Recovery console - Cmd prompt - navigating - yep, data files are still one week old. Removing the drive, mounting it under other Win7 installation. Still old data. Running NTFS undelete on the drive (read-only scan), searching for file created yesterday. Not found. Despair. At this point, idea: I will install a brand new Windows installation, keeping the old one in Windows.old (default behaviour of Windows installs). I boot the new install, I go to my C:\Data\ folder, I choose "Restore previous versions", click on yesterday's date, and click open... YES! It works! I can see the latest versions of my files (e.g. from yesterday). Thank God. And then, I try to view the files under the "yesterday snapshot-version" of c:\Users\MyAccount\Desktop ... And I get "Permission Denied" as soon as I try to open "Users\MyAccount". I make sure I am an administrator. No joy. Apparently, the new Windows installation does not have access to read the "NTFS snapshots" or "Volume Shadow Snapshots" of my old Windows account! Cross-installation permissions? I need to somehow tell the new Windows install that I am the same "old" user... So that I will be able to access the "Users\MyAccount" folder of the snapshot of my old user account. Help?

  • NTFS Error - file system structure is corrupt and unusable

    - by SomeGuy
    My Windows 7 (64) keeps completely locking up, and I have to hold the power button to shit it down. Event logs are showing EventID 55. I realize that this can be a warning sign of an impending disk failure, but my data on this machine is safely backed up and I don't feel like taking the time to replace the drive right now. When I have seen this problem before, I have been able to delete the offending folder with a Linux Live CD. (When CHKDSK /F didn't work). In this case, the folder is from VSS. I assume this is from Crashplan, my online backup provider. What are the ramifications of deleting this folder from Linux? Is it safe to do? "The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolumeShadowCopy26."

  • How to port VirtualBox machines with the recent snapshot?

    - by Liran Orevi
    I've ported a 'hard disk' using the 'clonehd' advice given on How to easily port VirtualBox machines? But it's not at the latest state, it's probably before any 'snapshot' was taken. I have only copied the 'hard disk', I haven't copied any 'snapshot' mainly because there are so many. I'm interested to transfer the 'hard disk' at it's latest state. How can this be done? (easily and not by coping the entire snapshots, machine etc...)
