  • Python 2.7 and Ubuntu 10.10: X11 fails

    - by c.a.p.
    Against every recommendation I have apt-get remove python in Ubuntu 10.10 (build 2.6.24-29-server x86_64) and apt-get install python2.7 Some built-in software with python2.6 dependencies (like firefox, other minor stuff) was fixed just by apt-get reinstalling or reinstalling from source and the system was stable for one day until I rebooted. Upon booting I got the message "ubuntu is running in low-graphics mode" I have an NVIDIA Quadro NVS 295 256 running on a HP Z600 Workstation so I sudoed: apt-get --purged nvidia* apt-get --purged xserver apt-get install linux-headers-generic apt-get install nvidia-* apt-get install xserver-xorg dpkg-reconfigure xserver-xorg nvidia-xconfig upon rebooting i get the same "ubuntu is running in low-graphics mode" if I decide to tell the boot menu to restart X, the Ubuntu 10.10 "load screen" shows up and does not do anything for hours. If I "X" the screen remains black for hours; ctrl-c shows that /etc/X11/xorg.conf did not produce any errors just a warning "Type "ONE_LEVEL"...". /var/log/Xorg.0.log issues the following warnings (no errors) (WW) AllowEmptyInput is on (WW) NVIDIA(0): UBB is incompatible If I "startX" I get /usr/bin/python: can't find '__main__.py"' in '/usr/share/command-not-found' Before re-installing xserver-xorg however "startX" ran, just by changing the resolution of the tty1 console. Any hints?

  • Unwanted blank lines when committing from SVN

    - by Alon_A
    I'm using CentOS Linux 5.8 as a web server and tortoise SVN for synchronizing version of our code. We write the code in Windows 7 professional 64BIT with NetBeans and NotePad++. I'm committing the code files (.php) from the Linux Shell by this command: svn co svnFolder serverFolder --username **** --password **** The problem is, after committing the files, when I'm opening them directly from the server (for debugging) by NotePad++ (I'm doing View/Edit from Filezilla) I have extra blank lines. A code that looks like this on the localhost (On NotePad++): private $producer; private $account; private $admin; private $producerEvents; private $accountProducers; private $adminAccounts; Will look like this after committing to the server (Again, on NotePad++): private $producer; private $account; private $admin; private $producerEvents; private $accountProducers; private $adminAccounts; If I upload files by FTP, No blank lines are being added. How can I solve it ? Thanks.

  • Strange network issue (ZIP file fails CRC test over VPN)

    - by Joe Schmoe
    We have a server in the office running Windows Server 2003 Our office is connected to our datacenter via hardware VPN (Linksys RV082 router in the office to CISCO router in the datacenter). There is a job that runs on the server in the office that does following: ZIP certain files from the server using 7Zip, copy ZIP file to a network share in the office and verify ZIP integrity, copy ZIP file to a network share in the data center and verify ZIP integrity. Problem is - verifying ZIP integrity for the file in the data center always fails. However, if I run 7Zip on the server in data center that exposes that share ZIP file verifies just fine, so it is not actually corrupted during copy operation. Additionally, I tried running ZIP on other computers in the office to verify ZIP file on datacenter file share and it verifies OK. I tried plugging server to the same network port where my workstation is connected using different cable (my workstation doesn't exhibit this problem) and ZIP verification still fails. So the problem is local to that specific server. On network adapter properties for the server in question there is no "Advanced" tab where one can usually configure a lot of network settings. Network card driver is up to date (Windows Update doesn't find anything newer and Lenovo website doesn't have any drivers for Windows 2003 for this computer model). Is there any other way to configure network setting via command line? What settings could be relevant to this problem?

  • Sed issue with numbers exceeding 9

    - by Imane Fateh
    May be my problem is kinda obvious for you but I really need to get a solution. I need to generate a file.sql file from a file.csv, so I use this command : cat file.csv |sed "s/\(.*\),\(.*\)/insert into table(value1, value2) values\('\1','\2'\);/g" > file.sql It works perfectly, but when the values exceed 9 (for example for \10, \11 etc...) it takes consideration of only the first number (which is \1 in this case) and ignores the rest. I want to know if I missed something or if there is another way to do it. Thank you ! EDIT : The not working example : My file.csv looks like 2013-04-01 04:00:52,2,37,74,40233964,3860,0,0,4878,174,3,0,0,3598,27.00,27 What I get insert into table val1,val2,val3,val4,val5,val6,val7,val8,val9,val10,val11,val12,val13,val14,val15,val16 values ('2013-04-01 07:39:43',2,37,74,36526530,3877,0,0,6080,2013-04-01 07:39:430,2013-04-01 07:39:431,2013-04-01 07:39:432,2013-04-01 07:39:433,2013-04-01 07:39:434,2013-04-01 07:39:435,2013-04-01 07:39:436); After the ninth element I get the first one instead of the 10th,11th etc...

  • Efficient mirroring of directories using hard links [closed]

    - by zoqaeski
    I'm backing up my music collection on to a number of NTFS-formatted external hard-drives; however, as I store my main collection in FLAC and have my library on my laptop as MP3s to save space, I want to be able to back up both sets, because mass conversion between formats is time-consuming. The "music" directory can contain any format; the "mp3s" directory contains only MP3s converted from files in the "music" directory. The music collection on the laptop contains only MP3s, but they come from both sources. When I backup my laptop's library to the "mp3s" directory, I want to only copy across MP3 files that don't exist in the "music" directory; those that do should be hard-linked to the "music" directory. All directories have an identical hierarchy, sorted by artist, album, date, discnumber if applicable, etc, and I use a tagging editor to ensure consistency across all these locations. I'm also using a Linux computer, but keeping the music collections on NTFS-formatted partitions so that they are readable by both Linux and Windows. At the moment, I use the following command to perform the backups, but this is time-consuming due to the expensive nature of finding hard links. rsync -avu --progress --relative --ignore-existing --link-dest=../music/ **/*.mp3 /media/ntfspocket/mp3s Is there a way to perform this backup more efficiently, taking advantage of the directory hierarchy?

  • Why am I getting kicked from an IRC channel in one OS (xp) but not in the other OS (7)? [closed]

    - by moshe
    I got kicked from an IRC channel. I have Windows XP and now if I'm trying to get into this specific channel, I get inside but I get immediately kicked out. I can come in again, and again get kicked out. It seems this is done automatically. Now I have also installed, on another hard drive in the same computer Windows 7. On Windows7 I can get into this same channel and never kicked out! It's the same computer, but different operating system(separate Hard Drives). How can it be? Is the KICK command bias towards the operating system I got KICKed in? Please explain to me how this thing is happening. PS: I forgot to mention that it doesn't matter if i change my IP or my nickname, I continue to kicked out from this channel. Again, in windows 7 I can get in without a problem. another thing that is good to mention is that i got kicked out when i was using windows XP, and not windows 7. i think that it could happened also with windows 2000 and vista, so i dont bother the OS itself, but why it's acting differently with a different OS?

  • The instruction at “0x7c910a19” referenced memory at “oxffffffff”. The memory could not be “read”

    - by ClareBear
    Hello guys/girls I have a small issue, I receive the following error before the .vbs terminates. I don't know why this error is thrown. Below is the process of the .vbs file: Call ImportTransactions() Call UpdateTransactions() Function ImportTransactions() Dim objConnection, objCommand, objRecordset, strOracle Dim strSQL, objRecordsetInsert Set objConnection = CreateObject("ADODB.Connection") objConnection.Open "DSN=*****;UID=*****;PWD==*****;" Set objCommand = CreateObject("ADODB.Command") Set objRecordset = CreateObject("ADODB.Recordset") strOracle = "SELECT query here from Oracle database" objCommand.CommandText = strOracle objCommand.CommandType = 1 objCommand.CommandTimeout = 0 Set objCommand.ActiveConnection = objConnection objRecordset.cursorType = 0 objRecordset.cursorlocation = 3 objRecordset.Open objCommand, , 1, 3 If objRecordset.EOF = False Then Do Until objRecordset.EOF = True strSQL = "INSERT query here into SQL database" strSQL = Query(strSQL) Call RunSQL(strSQL, objRecordsetInsert, False, conTimeOut, conServer, conDatabase, conUsername, conPassword) objRecordset.MoveNext Loop End If objRecordset.Close() Set objRecordset = Nothing Set objRecordsetInsert = Nothing End Function Function UpdateTransactions() Dim strSQLUpdateVAT, strSQLUpdateCodes Dim objRecordsetVAT, objRecordsetUpdateCodes strSQLUpdateVAT = "UPDATE query here SET [value:costing output] = ([value:costing output] * -1)" Call RunSQL(strSQLUpdateVAT, objRecordsetVAT, False, conTimeOut, conServer, conDatabase, conUsername, conPassword) strSQLUpdateCodes = "UPDATE query here SET [value:costing output] = ([value:costing output] * -1) different WHERE clause" Call RunSQL(strSQLUpdateCodes, objRecordsetUpdateCodes, False, conTimeOut, conServer, conDatabase, conUsername, conPassword) Set objRecordsetVAT = Nothing Set objRecordsetUpdateCodes = Nothing End Function It does both the import and update and seems to throw this error after. If I comment out the ImportTransactions it doesnt throw a error, however I have produced similar code for another vbs file and this does not throw any errors Thanks in advance for any help, Clare

  • very diferent results from df after few seconds

After ~20 sec the cycle closes. I'm again roughly by the same usage as earlier. The value is reasonable ca. 35 Mb were copied. Can somebody explain me what is going on? Does df only make an estimation of usage instead of used value?

  • CentOS and OpenSSH [on hold]

    - by Stephen
    I've recently installed CentOS 6 on an old Dell PC. I'm trying to setup OpenSSH at the moment, I been following some tutorials (http://www.youtube.com/watch?v=QKafb0koJEg) on You Tube, while they have been very helpful I'm at the point where I need to ask some questions. My goal here is to be able to access the server from my work computer and from my personal laptop (which will be on the same home network as the server). I've installed OpenSSH with no issues. So the first thing I was advised to do was port forwarding. So in the sshd_config file, I've changed Port 22 to Port xxxx (where xxxx is a obviously a four digit value). I then restart the sshd service. I've also configured my router for forward port 22 onto xxxx. Is there anything else I need to do? I've generated the keys on my laptop, and I'm trying to copy them to the server as follows: scp id_rsa.pub xxxxxxxx@localhost:.ssh/authorized_keys but this command fails with the following error message: ssh: connect to host localhost port 22: Connection refused lost connection Any help appreciated. Regards...

  • mysqld - master to slave replication using rsync innodb, sequence number issues

    - by Luis
    I've read several of the related topics posted here, but I have not been able to avoid this innodb error. The steps I've taken to replicate data from a Slackware server - 5.5.27-log (S) to a FreeBSD slave - 5.5.21-log (F) were these: (S) flush tables with read lock; (S) in another terminal show master status; (S) stop mysqld via command line in third terminal; (F) while both servers are stopped, rsync mysql datadir from (S), excluding master.info, mysql-bin and relay-* files; (F) start mysqld (skip-slave) 121018 12:03:29 InnoDB: Error: page 7 log sequence number 456388912904 InnoDB: is in the future! Current system log sequence number 453905468629. InnoDB: Your database may be corrupt or you may have copied the InnoDB InnoDB: tablespace but not the InnoDB log files. See InnoDB: http://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html InnoDB: for more information. This kind of error happens for a lot of tables. I know I can use dump, but the database is large, ca. 70GB and the systems are slow (old), so would like to get this replication to work with data transfer. What should I try to solve this issue?

  • Mac OS X - Time Machine backup fails verification - What can I do to save the history?

    - by usermac75
    Hi, How do I make Time Machine to make a new complete backup without losing older versions of backed up files? Verbose: I am using the Time Machine backup on my OS X (Snow Leopard) to backup the whole computer to an external drive. I especially like the "history", i.e. the feature that allows you to restore the older version of a file. Problem: I had some data corruption on my external backup drive, I repaired it with the System Tool for doing that, it found some faults. I had the disk tool repair the external drive. After that, the external drive was OK and I could use Time Machine again. I let Time Machine do one more backup. Now I made a verification according to http://superuser.com/questions/47628/verifying-time-machine-backups, namely along sudo diff -qr . $HOME/Desktop 2>&1 | tee $HOME/timemachine-diff.log However: After doing the command above, several differences and missing files were reported, approx. 200 files in sum. Whereas some of the missing files were cache or excluded directories, the differences do bother me, especially as some important documents from me are listed as differing. How can I make sure that the data on the external drive is synced correctly? Is it possible to have Time Machine to do a complete new backup without losing the history? Or to have Time Machine compare all files for differences and re-write all files that are different? Or can I set some flags on the files that do not match to have them copied again? (like the archive-flag in Windows/Dos). I'd rather not touch the files because I would like to keep the date of last change/date of creation) Thank you for your thoughts!

  • Very, very simple asp.net page takes forever to load

    - by John Hoge
    I've got a page that couldn't be more simple: <%@ Page Trace="true" %> <html> <head></head> <body> <h1>Hello World</h1> <a href="/OtherPage.aspx"/>Other Page</a> <p><%=DateTime.Now.ToString()%> </body> </html> ... but it takes forever to load. There is no database or web service call to slow it down. The trace command reveals that the time from Begin PreInot to End Render is .000049 seconds, but the page itself takes several seconds to load. It is a new web site I just created for this test, and just has a web.config & two test files. The only thing in the web.config is access control: <authorization><allow users="domain\me" /><deny users = "*"/></authorization> What else could IIS be doing with all of that time?

  • Memory Usage by Mapped Files (Win7 64Bit)

    - by Dexter
    When copying files from/to my external USB3 HDD memory usage in Win7 goes up to 100% and remains there. I'm not sure whether this is a problem caused by faulty drivers or not, but I already have the current version of them (Etron USB3 controller on a Gigabyte 990fxa board).. Using RAMMap it becomes obvious that the files, that are to be copied, are mapped into memory. Clicking on Empty > Empty System Working Set seems to temporarily fix the problem (without causing any trouble with the file copy process), but it needs to be done every few seconds. Is there any way to schedule this operation to happen ever 10 or so seconds on its own? What underlying system command is RAMMap using? Or, alternatively, is there any way to limit how much RAM mapped files may use in Windows 7? I know mapped files would usually be removed from memory if other programs need the memmory, but while memmory usage is at 100% the system starts freezing up for half a second or so everytime I click anything .. thus the automatic removal of unused memory contents seems to be failing here.

  • NFS server hangs after 3 minutes

    - by John P
    I have a VPS running Centos 6.3 with a fully updated NFS. When I mount the NFS directory from the client, everything works perfectly fine for approximately 3 minutes, then the client hangs attempting to see the directory. nfs-utils-1.2.3-26.el6.x86_64 service nfs status rpc.svcgssd is stopped rpc.mountd (pid 2544) is running... nfsd (pid 2609 2608 2607 2606 2605 2604 2603 2602) is running... rpc.rquotad (pid 2540) is running... cat /etc/exports /home/user XX.XX.XX.20(rw,async,no_root_squash) The client is running Centos 5.8. The directory is mounted using mount x.x.x.6:/home/user /mnt When everything is working, I get the following on the client: /usr/sbin/rpcinfo -p X.X.X.6 | grep mountd 100005 1 udp 892 mountd 100005 1 tcp 892 mountd 100005 2 udp 892 mountd 100005 2 tcp 892 mountd 100005 3 udp 892 mountd 100005 3 tcp 892 mountd When it stops working, rpcinfo just hangs on the client, however running the above command on the server does return data. There are no logs on the NFS Server side that would indicate an issue. On the client side, I see: cat /var/log/messages kernel: nfs: server X.X.X.6 not responding, still trying The client and server are plugged into the same switch, however they are on different networks. The server is a VPS while the client is a dedicated box. SELINUX is in permissive mode on both client and server, and I've turned iptables off on the server to make sure that was not causing an issue. Any ideas would be helpful - right now I'm having to restart NFS every two minutes in a cron job to keep it semi working. Thanks

  • 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

  • Change "Show Desktop" to "Minimize All"

    - by V0R73X
    I'd like to use Alt-Tab a lot when I'm programming under Windows. It's the quickest method to switch between windows. However, there's one annoying thing about this, and that is when I switch over to "Desktop" using Alt-Tab, Windows uses the "Show Desktop" command instead of minimizing all Windows. I personally hate Show Desktop, since it creates a separate window on top of all the other windows which captures a live display of desktop, and this causes all the widgets I have on the desktop to be hidden under this live window, and I LOVE my widgets. An ideal behavior for when I switch tabs to Desktop using Alt-Tab would be the "Minimize All" behavior, which simply minimizes all windows, leaving me with my actual desktop, which sits behind everything. In order to achieve this, I have to move my fingers across the keyboard, and press Win+M. This decreases my efficiency by .5 seconds, which is a LOT of time. How can I tell windows to use "Minimize All" rather than "Show Desktop" when I use my good ol' Alt-Tab functionality to switch over to desktop and save .5 seconds in time?

After ~20 seconds the cycle closes. I'm again roughly at the same usage as earlier. The value is reasonable, ca. 35 Mb were copied. Can somebody explain to me what is going on? Does df only make an estimation of usage instead of used value?

  • Return Json causes save file dialog in asp.net mvc

    - by Eran
    Hi, I'm integrating jquery fullcalendar into my application. Here is the code i'm using: in index.aspx: <script type="text/javascript"> $(document).ready(function() { $('#calendar').fullCalendar({ events: "/Scheduler/CalendarData" }); }); </script> <div id="calendar"> </div> Here is the code for Scheduler/CalendarData: public ActionResult CalendarData() { IList<CalendarDTO> tasksList = new List<CalendarDTO>(); tasksList.Add(new CalendarDTO { id = 1, title = "Google search", start = ToUnixTimespan(DateTime.Now), end = ToUnixTimespan(DateTime.Now.AddHours(4)), url = "www.google.com" }); tasksList.Add(new CalendarDTO { id = 1, title = "Bing search", start = ToUnixTimespan(DateTime.Now.AddDays(1)), end = ToUnixTimespan(DateTime.Now.AddDays(1).AddHours(4)), url = "www.bing.com" }); return Json(tasksList,JsonRequestBehavior.AllowGet); } private long ToUnixTimespan(DateTime date) { TimeSpan tspan = date.ToUniversalTime().Subtract( new DateTime(1970, 1, 1, 0, 0, 0)); return (long)Math.Truncate(tspan.TotalSeconds); } public ActionResult Index() { return View("Index"); } I also have the following code inside head tag in site.master: <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server" /> <link href="<%= Url.Content("~/Content/jquery-ui-1.7.2.custom.css") %>" rel="stylesheet" type="text/css" /> <link href="~Perspectiva/Content/Site.css" rel="stylesheet" type="text/css" /> <link href="~Perspectiva/Content/fullcalendar.css" rel="stylesheet" type="text/css" /> <script src="~Perspectiva/Scripts/jquery-1.4.2.js" type="text/javascript"></script> <script src="~Perspectiva/Scripts/fullcalendar.js" type="text/javascript"></script> <script src="/Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script> <script src="/Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script> Everything I did was pretty much copied from http://szahariev.blogspot.com/2009/08/jquery-fullcalendar-and-aspnet-mvc.html When navigating to /scheduler/calendardata I get a prompt for saving the json data which contents are exactly what I created in the CalendarData function.

  • OCR an RSA key fob (security token)

    - by user130582
    I put together a quick WinForm/embedded IE browser control which logs into our company's bank website each morning and scrapes/exports the desired deposit information (the bank is a smallish regional bank). Since we have a few dozen "pseudoaccounts" that draw from the same master account, this actually takes 10-15 minutes to retrieve. Anyway, the only problem is that our business bank account reuires an RSA security token (http://www.rsa.com/node.aspx?id=1156)--if you are not familiar, it is a small device which shows a random 6 digit number every 15(?) seconds, so I have to prompt for this value before starting. This is on top of the website's login based security model, so even if you create a read-only account that can't do anything, you still have to put the RSA number in. We have 5 of these tokens for different people in the company. From our perspective this is nusiance security. I was joking about using a web camera to OCR the digits from the key fob so they didn't have to type it in -- mainly so that the scraping/export would be done before anyone arrives in the morning. Well, they asked if I could really do it. So now I ask you, how hard (how many hours) do you think it would take to OCR these digits reliably from a JPEG image produced by the camera? I already know I can get the JPEG easily. I think you get 3 tries to log in, so it really needs to hit a 99% accuracy rate. I could work on this on my off time, but they don't want me to put more than a few hours into it, so I want to leverage as much existing code as possible. This is a 7-segment display (like an alarm clock) so it's not exactly text that an OCR package would be used to seeing. Also--there is a countdown timer on the side of the display; typically when it is down to 1 bar, you wait until the next number appears and it starts over at 5 bars (like signal strength on your cell phone). So this would need to be OCRd as well but it is not text. Anyway the more I think about it as I type this, the less convinced I am that I can truly get this right, so maybe I should just work on it in my spare time?

  • Vs2010 MvcBuildViews Not firing

    This project in Vs2008 targeting .net 3.5 used to compile views. Vs2010 Targeting .net 4.0 the following view code is not picked up as an error, and I have not found anyway to listen to the mvcBuildview trace/debug output: <%{ %> A completely unmatched code block declaration is not being picked up, neither was a partial view inheriting from a non existent namespace/class. <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'DebugWithBuildViews|AnyCPU' "> <!--<BaseIntermediateOutputPath>bin/intermediate</BaseIntermediateOutputPath>--> <!--<MvcBuildViews Condition=" '$(Configuration)' == 'DebugWithBuildViews' ">true</MvcBuildViews>--> <EnableUpdateable>false</EnableUpdateable> <MvcBuildViews>true</MvcBuildViews> <DebugSymbols>true</DebugSymbols> <OutputPath>bin</OutputPath> <DefineConstants>DEBUG;TRACE</DefineConstants> <DebugType>full</DebugType> <PlatformTarget>AnyCPU</PlatformTarget> <CodeAnalysisUseTypeNameInSuppression>true</CodeAnalysisUseTypeNameInSuppression> <CodeAnalysisModuleSuppressionsFile>GlobalSuppressions.cs</CodeAnalysisModuleSuppressionsFile> <ErrorReport>prompt</ErrorReport> <CodeAnalysisRuleSet>AllRules.ruleset</CodeAnalysisRuleSet> <RunCodeAnalysis>true</RunCodeAnalysis> </PropertyGroup> My BeforeBuild: <Target Name="BeforeBuild"> <WriteLinesToFile File="$(OutputPath)\env.config" Lines="$(Configuration)" Overwrite="true"> </WriteLinesToFile> My AfterBuild: <Target Name="AfterBuild" Condition="'$(MvcBuildViews)'=='true'"> <!--<BaseIntermediateOutputPath>[SomeKnownLocationIHaveAccessTo]</BaseIntermediateOutputPath>--> <Message Importance="high" Text="Precompiling views" /> <!--<AspNetCompiler VirtualPath="temp" PhysicalPath="$(ProjectDir)..\$(ProjectName)" />--> <!--<AspNetCompiler VirtualPath="temp" />--> <!--PhysicalPath="$(ProjectDir)\..\$(ProjectName)"--> I know the MvcBuildViews property is true because the Precompiling views message comes through. The compile is a success but it does not catch the view compilation errors. I have Vs2010 ultimate, vs 2008 developer+database edition on this machine. So either it compiles ignoring the errors with some combinations of the fixes I've tried, or it errors with Error 410 It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. web.config 100 The commented out sections are things I have tried Previously I have tried the fixes from these posts: Compile Views in Asp.net Mvc AllowDefinitionMachinetoApplicationError MvcBuildviews Issue Turning on MVC Build Views in 2010 TFS Johnny Coder

  • Save gcc compile status to a text file for Java

    - by JohnBore
    I'm making a C Assessment Program through Java, which has a bunch of programming questions for C, and it lets the user input an answer in the form of C code, and then press a "Compile" button, which is linked to a bat file that runs the user input code through gcc. I've got the input and compiling working, but I need to get the output from the compiler and get that to print textarea within the program. I can get a simple "Hello, world" compiling, but I'm having trouble getting programs that require a user input with scanf, for example, to be printed. else if(e.getSource().equals(compile)){ if(questionNumber<1){ JOptionPane.showMessageDialog(programFrame, "Please start the assessment", "Compile Error", JOptionPane.ERROR_MESSAGE); } else{ FileOutputStream fileWrite; try { fileWrite = new FileOutputStream("demo/demo.c"); new PrintStream(fileWrite).println(input.getText());//saves what the user has entered in to a C source file fileWrite.close(); @SuppressWarnings("unused") Process process = Runtime.getRuntime().exec("cmd /c compile.bat");//runs the batch file to compile the source file compileCode(); try{ fileStream = new FileInputStream("demo/output.txt"); inputStream = new DataInputStream(fileStream); bufferRead = new BufferedReader(new InputStreamReader(inputStream)); while((stringLine = bufferRead.readLine())!=null){ compiled.append(stringLine); compiled.append("\n"); } inputStream.close(); } catch(IOException exc){ System.err.println("Unable to read file"); System.exit(-1); } } catch (IOException exc) { JOptionPane.showMessageDialog(programFrame, "Demo file not found", "File Error", JOptionPane.ERROR_MESSAGE); } } This is the actionPerformed method for the "Compile" button, the compileCode() is the JFrame that displays the output and "compiled" is the textArea for the output. My batch file is: C: cd dev-cpp\bin gcc.exe H:\workspace\QuestionProgram\demo\demo.c -o demo > H:\workspace\QuestionProgram\demo\compilestatus.txt demo > H:\workspace\QuestionProgram\demo\output.txt I'm not sure how I can do it, so the frame is created for the output of the code if the code requires a user input as the command prompt doesn't open without adding "START" to .exec(), but then the frame appears before the program has finished running. Also, how would I get the output of the compiler if the compile fails because of an error? The way I've got it in my batch file at the moment doesn't put anything in a text file if it fails.

  • Facebook Developer ToolKit: How should I construct this app?

    - by j0nscalet
    I have created a simple desktop application that I want to use to post status updates for the users of my app. Here's the kicker though that I am having trouble figuring out, the desktop application runs as part of a batch process every night, in which I update the status of certain users. I use the following code to accomplish this: (comes directly from the FDK samples) public FriendViewer() { InitializeComponent(); facebookService1.ApplicationKey = "Key"; facebookService1.Secret = "Secret"; facebookService1.SessionKey = "Session key"; facebookService1.IsDesktopApplication = true; } private void TestService_Load(object sender, EventArgs e) { try { if (!facebookService1.API.users.hasAppPermission(facebook.Types.Enums.Extended_Permissions.status_update)) facebookService1.GetExtendedPermission(facebook.Types.Enums.Extended_Permissions.status_update); if (!facebookService1.API.users.hasAppPermission(facebook.Types.Enums.Extended_Permissions.offline_access)) facebookService1.GetExtendedPermission(facebook.Types.Enums.Extended_Permissions.offline_access); long uid = facebookService1.users.getLoggedInUser(); facebook.Schema.user user = facebookService1.users.getInfo(uid); facebookService1.users.setStatus("Facebook Syndicator rules!"); MessageBox.Show(String.Format("Status set for {0} {1}", user.first_name, user.last_name)); } catch (Exception ex) { MessageBox.Show(ex.Message); Close(); } } My user's day to day activity is done a website front end. Since I dont have any user interaction in a nightly batch process, I cannot use the ConnectToFaceBook method on the FaceBookService to obtain a sessionKey for the user. Ideally I would like to prompt for authorization and extended permissions for my desktop app when a user logins into the web front end then save the sessionKey and uid in the database. At night when my process runs, I would reference the sessionKey and uid in order and update the user's status. I am finding myself fumbling between whether or not my app should be a web or desktop app. Having both a web and desktop app would be confusing to my users, because they would have to grant/manage permissions for both apps. And I looking at this the wrong way? Any help would be greatly appreciated! Thanks.

  • Stack Overflow problem in a recursive program in C

    - by Adi
    Hi all, I am getting a stack overflow in one of the recursive functions i am running.. Here is the code.. void* buddyMalloc(int req_size) { // Do something here return buddy_findout(original_index,req_size); // This is the recursive call } void *buddy_findout(int current_index,int req_size) { char *selected = NULL; if(front!=NULL) { if(current_index==original_index) { // Do something here return selected; } else { // Do Something here return buddy_findout(current_index+1,req_size); } } else { return buddy_findout(current_index-1,req_size); } } Consider the initial value of index to be 4. and it first do index-1 till it reaches 0 index. and then it comes back to index 4 by incrementing..This is wht i want to implement. But it gives a stack overflow with memory map in the command prompt : Here is the output from my shell : * glibc detected * ./473_mem: free(): invalid pointer: 0x00c274c0 * ======= Backtrace: ========= /lib/tls/i686/cmov/libc.so.6[0xb50ff1] /lib/tls/i686/cmov/libc.so.6[0xb526f2] /lib/tls/i686/cmov/libc.so.6(cfree+0x6d)[0xb557cd] ./473_mem[0x8048b44] ./473_mem[0x8048b74] ./473_mem[0x8048b74] ./473_mem[0x8048944] ./473_mem[0x8048c87] ./473_mem[0x8048d31] ./473_mem[0x8048f79] /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe6)[0xafcb56] ./473_mem[0x8048671] ======= Memory map: ======== 0017c000-00198000 r-xp 00000000 08:01 5224 /lib/libgcc_s.so.1 00198000-00199000 r--p 0001b000 08:01 5224 /lib/libgcc_s.so.1 00199000-0019a000 rw-p 0001c000 08:01 5224 /lib/libgcc_s.so.1 00260000-00284000 r-xp 00000000 08:01 1927 /lib/tls/i686/cmov/libm-2.10.1.so 00284000-00285000 r--p 00023000 08:01 1927 /lib/tls/i686/cmov/libm-2.10.1.so 00285000-00286000 rw-p 00024000 08:01 1927 /lib/tls/i686/cmov/libm-2.10.1.so 006cd000-006e8000 r-xp 00000000 08:01 6662 /lib/ld-2.10.1.so 006e8000-006e9000 r--p 0001a000 08:01 6662 /lib/ld-2.10.1.so 006e9000-006ea000 rw-p 0001b000 08:01 6662 /lib/ld-2.10.1.so 00aa9000-00aaa000 r-xp 00000000 00:00 0 [vdso] 00ae6000-00c24000 r-xp 00000000 08:01 1900 /lib/tls/i686/cmov/libc-2.10.1.so 00c24000-00c25000 ---p 0013e000 08:01 1900 /lib/tls/i686/cmov/libc-2.10.1.so 00c25000-00c27000 r--p 0013e000 08:01 1900 /lib/tls/i686/cmov/libc-2.10.1.so 00c27000-00c28000 rw-p 00140000 08:01 1900 /lib/tls/i686/cmov/libc-2.10.1.so 00c28000-00c2b000 rw-p 00000000 00:00 0 08048000-0804a000 r-xp 00000000 00:14 2176 /media/windows-share/OS/Project2/473_mem 0804a000-0804b000 r--p 00001000 00:14 2176 /media/windows-share/OS/Project2/473_mem 0804b000-0804c000 rw-p 00002000 00:14 2176 /media/windows-share/OS/Project2/473_mem 08483000-084a4000 rw-p 00000000 00:00 0 [heap] b7600000-b7621000 rw-p 00000000 00:00 0 b7621000-b7700000 ---p 00000000 00:00 0 b7716000-b7819000 rw-p 00000000 00:00 0 b7827000-b782a000 rw-p 00000000 00:00 0 bfb96000-bfbab000 rw-p 00000000 00:00 0 [stack] Aborted Thanks in advance adi
