  • Distinguishing between failure and end of file in read loop

    - by celtschk
    The idiomatic loop to read from an istream is while (thestream >> value) { // do something with value } Now this loop has one problem: It will not distinguish if the loop terminated due to end of file, or due to an error. For example, take the following test program: #include <iostream> #include <sstream> void readbools(std::istream& is) { bool b; while (is >> b) { std::cout << (b ? "T" : "F"); } std::cout << " - " << is.good() << is.eof() << is.fail() << is.bad() << "\n"; } void testread(std::string s) { std::istringstream is(s); is >> std::boolalpha; readbools(is); } int main() { testread("true false"); testread("true false tr"); } The first call to testread contains two valid bools, and therefore is not an error. The second call ends with a third, incomplete bool, and therefore is an error. Nevertheless, the behaviour of both is the same. In the first case, reading the boolean value fails because there is none, while in the second case it fails because it is incomplete, and in both cases EOF is hit. Indeed, the program above outputs twice the same line: TF - 0110 TF - 0110 To solve this problem, I thought of the following solution: while (thestream >> std::ws && !thestream.eof() && thestream >> value) { // do something with value } The idea is to detect regular EOF before actually trying to extract the value. Because there might be whitespace at the end of the file (which would not be an error, but cause read of the last item to not hit EOF), I first discard any whitespace (which cannot fail) and then test for EOF. Only if I'm not at the end of file, I try to read the value. For my example program, it indeed seems to work, and I get TF - 0100 TF - 0110 So in the first case (correct input), fail() returns false. Now my question: Is this solution guaranteed to work, or was I just (un-)lucky that it happened to give the desired result? Also: Is there a simpler (or, if my solution is wrong, a correct) way to get the desired result?

  • RoR custom routing/Method/View problem all methods come back as undefined

    - by Jeff
    I am playing with custom view and routes. I think that I have everything right but obviously not. Essentially I tried to copy the show method and show.html.erb but for some reason it will not work. My controller class fatherController < ApplicationController def show @father = Father.find(params[:id]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @father } end end def ofmine @father = Father.find(params[:id]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @father } end end end My routes.rb Parent::Application.routes.draw do resources :fathers do resources :kids end match 'hospitals/:id/ofmine' => 'father#show2' end when I go to 127.0.0.1:/father/1 it works fine but when I try to go to 127.0.0.1:/father/1/ofmine it gives the following error. It doesn't matter what the variable/method that is called; it occurs at the first one to be displayed. Both show.html.erb and show2.html.erb are the exact same files My Error from webserver commandline > Processing by fathersController#show2 > as HTML Parameters: {"id"=>"1"} > Rendered fathers/show2.html.erb within > layouts/application (31.6ms) Completed > in 37ms > > ActionView::Template::Error (undefined > method `name' for nil:NilClass): > 4: <td>Name</td><td></td> > 5: </tr> > 6: <tr> > 7: <td><%= @father.name %></td><td></td> > 8: </tr> > 9: <tr> > 10: <td>City</td><td>State</td> app/views/fathers/show2.html.erb:7:in > `_app_views_fatherss_show__html_erb___709193087__616989688_0' Error as displayed on actual page NoMethodError in Fathers#show2 Showing /var/ruby/chs/app/views/fathers/show2.html.erb where line #7 raised: undefined method `name' for nil:NilClass Extracted source (around line #7): 4: Name 5: 6: 7: <%= @father.name % 8: 9: 10: CityState If anyone could tell me what in the world I am doing wrong I would appreciate it greatly.

  • Installing XP through USB-flash disc

    - by Crazy Buddy
    I don't know whether this could be asked here... So, Pardon me for this. Probably, this is based on My laptop and a contradiction to this question asked already here... I tried to format my "government-provided" laptop (No CD-drive). I thought those IT guys are proving that they're too smart..! I have the Windows XP CD right now. I didn't like to stick with some home-made OS from our Government. So, I used another laptop to format the govt. thing and tried to install XP (As I didn't have enough bills to invest on Windows 7 or 8). Case 1: First, I allowed WinSetupFromUSB 1.0 beta 8 to deal with the flash disk. I wondered for the first time that XP text-screen appeared. Using the first part, I formatted my laptop. It started to copy files, entered into the next part, and completed the installation. I started my PC for the first time. XP splash screen appeared. Suddenly, a blue screen flashed and disappeared (I can't even read what it says). Rebooted and arrived at the screen, "Start Windows Normally". It happens and happens still - like an infinite loop :-) Case 2: Next, I used Rufus 1.2.0 to transfer files to my Flash and it screwed everything out. Even if I used Flash to boot, it arrives to the same screen "Start Windows normally". It doesn't show any response of Flash being inserted. Then I recognized that, It's simply copies everything to the flash disk. Case 3: Then, I started with Novicorp WinToFlash (giving utmost priority to this site). I booted with the disk. I entered into the first part - "Text mode". Some lines started running like that "Press F6 if you..." like that. The last thing I saw was, "Setup is starting Windows..." Suddenly a blue screen appeared like this captured one. I've a suspicion that the same screen appears again & again in first case. Man, I'm dead. Case 4: For the sake of my last hope, I used WinSetupFromUSB 0.1.1. I was shocked on arriving at a screen which says something "GRUB4DOS" like that and some commands like {command line, reboot, halt, \find menu.lst} and when I go inside those "find" options, I see "Error:15 - File not found". Googling provided some commands to mount SETUPLDR.BIN file in the "grub" thing which also proved unsuccessful... Some sites say that Factory reset uses only some function keys. A guy said that it's F11 for lenovo. Screw him. It's all a waste-of-time. But, I think SE would help me out. Is our government IT guys doin' this to me? Are they Soooo smart to spark some blue screen in front of me to freak me out? Any suggestions or new (useful) USB transferring things would be appreciated. It's very urgent. So, It'd be better if you guys pay some attention in debugging and help me out..? Thanks for your time guys :-)

  • netsh.exe: Error 87

    - by Ben
    I'm having some trouble creating a urlacl reservation in Windows Server 2008; probably this a rookie mistake. The command line I'm using is: netsh http add urlacl url=http://+:99898/ user=ben The error that I see is: Url reservation add failed, Error: 87 The parameter is incorrect. There is a local user account named 'ben' that has admin privileges. I've made sure to put a trailing slash after the port number in the URL. Google and MSDN documentation are letting me down now - does anyone have any clue what I'm doing incorrectly?

  • Cisco VPN error 403: Unable to contact the security gateway

    I'm trying to make a connection via Cisco VPN Client (version is 5.0.07.0290), but i get the below mentioned error. I have to say that i'm using Windows 8. "Secure VPN Connection terminated locally by the Client. Reason 403: Unable to contact the security gateway." I've tried several fixes, but none of them worked. The display name in regedit is the correct, and my certificates are ok as well. If i switch to TCP (the default is UDP) i get error 414. Firewall is off. Any suggestions will be appreciated.

  • Group Policy drive maps fail with Error Code: 0x80070043

    - by Topherhead
    I'm running a Server 2008 R2 domain with all Windows 7 x64 bit client machines. All drives are mapped using Group Policy. Which were previously on a NAS We just built a new, huge, fast server. So I'm in the process of migrating all the network drives from the NAS to the new fileserver(fs). The old drive maps were mapped using group policy so I just went in and updated to the new server and selected the "Replace" option. But the drives just plain do not map. I do an RSOP on my machine and the error for the drive map is: Result: Failure (Error Code: 0x80070043) The other odd thing, though it may or may not have anything to do with it, is that the winning GPO shown is shown with its SID instead of its name. The SID is correct though. Accessing the shares through Explorer works fine, and mapping them manually works fine. Any ideas? Thanks Chris

  • Windows service - COM class factory error 80070583

    - by jawonlee
    I have a Windows service that periodically scrapes some web pages, using mshtml and HtmlAgilityPack. For this particular C# code snippet: HTMLDocumentClass doc = new HTMLDocumentClass(); doc.write(new object[] { responseFromServer }); doc.close(); I get this error: Retrieving the COM class factory for component with CLSID {25336920-03F9-11CF-8FD0-00AA00686F13} failed due to the following error: 80070583. I tracked down the CLSID in the registry, and it turned out to be mshtml.dll. I also noticed that the version I actually have is version 7.0.6000.17023, and the registry version is listed as Version=7.0.3300.0. The error code 80070583 means "Class does not exist"; interestingly, I've also gotten an error from the same program with error code 80070582, or "Class already exists". What does it all mean? Edit: Since there are no answers, I ended up working around the problem, by ditching MSHTML and using HTML Agility Pack to parse HTML. How do I close this question?

  • 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
