  • How do I join three tables with SQLalchemy and keeping all of the columns in one of the tables?

    - by jimka
    So, I have three tables: The class defenitions: engine = create_engine('sqlite://test.db', echo=False) SQLSession = sessionmaker(bind=engine) Base = declarative_base() class Channel(Base): __tablename__ = 'channel' id = Column(Integer, primary_key = True) title = Column(String) description = Column(String) link = Column(String) pubDate = Column(DateTime) class User(Base): __tablename__ = 'user' id = Column(Integer, primary_key = True) username = Column(String) password = Column(String) sessionId = Column(String) class Subscription(Base): __tablename__ = 'subscription' userId = Column(Integer, ForeignKey('user.id'), primary_key=True) channelId = Column(Integer, ForeignKey('channel.id'), primary_key=True) And the SQL commands that are executed to create them: CREATE TABLE subscription ( "userId" INTEGER NOT NULL, "channelId" INTEGER NOT NULL, PRIMARY KEY ("userId", "channelId"), FOREIGN KEY("userId") REFERENCES user (id), FOREIGN KEY("channelId") REFERENCES channel (id) ); CREATE TABLE user ( id INTEGER NOT NULL, username VARCHAR, password VARCHAR, "sessionId" VARCHAR, PRIMARY KEY (id) ); CREATE TABLE channel ( id INTEGER NOT NULL, title VARCHAR, description VARCHAR, link VARCHAR, "pubDate" TIMESTAMP, PRIMARY KEY (id) ); NOTE: I know user.username should be unique, need to fix that, and I'm not sure why SQLalchemy creates some row names with the double-quotes. And I'm trying to come up with a way to retrieve all of the channels, as well as an indication on what channels one particular user (identified by user.sessionId together with user.id) has a subscription on. For example, say we have four channels: channel1, channel2, channel3, channel4; a user: user1; who has a subscription on channel1 and channel4. The query for user1 would return something like: channel.id | channel.title | subscribed --------------------------------------- 1 channel1 True 2 channel2 False 3 channel3 False 4 channel4 True This is a best-case result, but since I have absolutely no clue as how to accomplish the subscribed column, I've been instead trying to get the particular users id in the rows where the user has a subscription and where a subscription is missing, just leave it blank. The database engine that I'm using together with SQLalchemy atm. is sqlite3 I've been scratching my head over this for two days now, I've no problem joining together all three by way of the subscription table but then all of the channels where the user does not have a subscription gets omitted. I hope I've managed to describe my problem sufficiently, thanks in advance.

  • How do I configure multiple Ubuntu Python installations to avoid App Engine's SSL error?

    - by Linc
    I have Karmic Koala which has Python 2.6 installed by default. However I can't run any Python App Engine projects because they require Python 2.5 and python ssl. To install ssl I installed python2.5-dev first while following some instructions I found elsewhere. sudo apt-get install libssl-dev sudo apt-get install python-setuptools sudo apt-get install python2.5-dev sudo easy_install-2.5 pyopenssl However, I am afraid this is not good for my Ubuntu installation since Ubuntu expects to see version 2.6 of Python when you type 'python' on the command line. Instead, it says '2.5.5'. I tried to revert to the original default version of Python by doing this: sudo apt-get remove python2.5-dev But that didn't seem to do anything either - when I type 'python' on the command line it still say 2.5.5. And App Engine still doesn't work after all this. I continue to get an SSL-related error whenever I try to run my Python app: AttributeError: 'module' object has no attribute 'HTTPSHandler' UPDATE: Just checked whether SSL actually installed as a result of those commands by typing this: $ python2.5 Python 2.5.5 (r255:77872, Apr 29 2010, 23:59:20) [GCC 4.4.1] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import ssl Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named ssl >>> As you can see, SSL is still not installed, which explains the continuing App Engine error. If anyone knows how I can dig myself out of this hole, I would appreciate it.

  • Windows batch - loop over folder string and parse out last folder name

    - by Tim Peel
    Hi, I need to grab the folder name of a currently executing batch file. I have been trying to loop over the current directory using the following syntax (which is wrong at present): set mydir = %~p0 for /F "delims=\" %i IN (%mydir%) DO @echo %i Couple of issues in that I cannot seem to pass the 'mydir' variable value in as the search string. It only seems to work if I pass in commands; I have the syntax wrong and cannot work out why. My thinking was to loop over the folder string with a '\' delimiter but this is causing problems too. If I set a variable on each loop then the last value set will be the current folder name. For example, given the following path: C:\Folder1\Folder2\Folder3\Archive.bat I would expect to parse out the value 'Folder3'. I need to parse that value out as its name will be part of another folder I am going to create further down in the batch file. Many thanks if anyone can help. I may be barking up the wrong tree completely so any other approaches would be greatly received also. Tim

  • Having trouble with confusing behaviour of error between debug and release modes in Xcode

    - by Cocorico
    Hi guys, I am confused over something (what is new!). I have an iPhone program I am writing and using some sqlite in a certain method, and there is some error which is giving me a message that says "Program received signal: “EXC_BAD_ACCESS” Okay, so I am trying to hunt down why this is doing this, and I notice something: When I run the program in debug mode, it gives me this error every single time I access this method (I test on the device). However when I run the program in release mode, I can access this method 2 times, and then it will give me this error the third time. So I mean, can someone just give me an explanation of what might cause this, I think that maybe deep-down I am not that smart on the difference in XCode of debug and release modes. I think that release mode does optimizing, and I guess the actual assembly machine code comes out different, yes? I AM A BIG NEWBIE USER UNFORTUNATELY! I am not clear on a lot of things like this, or whether it needs for I to remove nslog commands in the release build and such. Maybe I should just post the actual code in separate Stack OVerflow post, and see if people can see the error, then maybe this all become clear to me.

  • CakePHP: Missing database table

    - by Justin
    I have a CakePHP application that is running fine locally. I uploaded it to a production server and the first page that uses a database connection gives the "Missing Database Table" error. When I look at the controller dump, it's complaining about the first table. I've tried a variety of things to fix this problem, with no luck: I've confirmed that at the command line I can login with the given MySQL credentials in database.php I've confirmed this table exists I've tried using the MySQL root credentials (temporarily) to see if the problem lies with permissions of the user. The same error appeared. My debug level is currently set to 3 I've deleted the entire contents of /app/tmp/cache I've set 777 permissions on /app/tmp* I've confirmed that I can run DESCRIBE commands at the commant line MySQL when logged in with the MySQL credentials used by by the application I've verified that the CakePHP log file only contains the error I'm setting in the browser window. I've tried all the suggestions I could find in similar postings on SO I've Googled around and didn't find any other ideas I think I've eliminating the obvious problems and my research isn't turning anything up. I feel like I'm missing something obvious. Any ideas?

  • Creating a Multiwindowed Cocoa Program - Launching Procedure Suggestions?

    - by Jeffrey Kern
    I'm porting an application I developed in Visual Studio 2008 over to Cocoa. I'm currently doing a 'learn-as-you-go' approach to Cocoa, so I can experiment with different ideas and techniques in smaller, simpler projects and eventually combine them into one big application. My program logic is as follows (in a dumbed-down sense). Items in the list are mandated by my boss. Application is started 1a. Verify CD program is in drive. Verify license. If found and is valid, skip to step 7 Display license agreement. Display serial number prompt. Verify and save serial number. Hide all prior windows. Load main application window Intercept requests and commands from main application window, including making a duplicate main application window Exit program when requested by user What would the best bet be for this type of application? From another question I asked, I found out that I should keep the 'main application' window in a separate XIB file from the rest, because I might need to clone and interact with it. I know that since Cocoa and Objective-C is based off of C, there is a Main method somewhere. But what would you all suggest as a starting place for an application like this?

  • Minimal "Task Queue" with stock Linux tools to leverage Multicore CPU

    - by Manuel
    What is the best/easiest way to build a minimal task queue system for Linux using bash and common tools? I have a file with 9'000 lines, each line has a bash command line, the commands are completely independent. command 1 > Logs/1.log command 2 > Logs/2.log command 3 > Logs/3.log ... My box has more than one core and I want to execute X tasks at the same time. I searched the web for a good way to do this. Apparently, a lot of people have this problem but nobody has a good solution so far. It would be nice if the solution had the following features: can interpret more than one command (e.g. command; command) can interpret stream redirects on the lines (e.g. ls > /tmp/ls.txt) only uses common Linux tools Bonus points if it works on other Unix-clones without too exotic requirements.

  • git rebase without changing commit timestamps

    - by Olivier
    Would it make sense to perform git rebase while preserving the commit timestamps? I believe a consequence would be that the new branch will not necessarily have commit dates chronologically. Is that theoretically possible at all? (e.g. using plumbing commands; just curious here) If it is theoretically possible, then is it possible in practice with rebase, not to change the timestamps? For example, assume I have the following tree: master <jun 2010> | : : : oldbranch <feb 1984> : / oldcommit <jan 1984> Now, if I rebase oldbranch on master, the date of the commit changes from feb 1984 to jun 2010. Is it possible to change that behaviour so that the commit timestamp is not changed? In the end I would thus obtain: oldbranch <feb 1984> / master <jun 2010> | : Would that make sense at all? Is it even allowed in git to have a history where an old commit has a more recent commit as a parent? Edit A crucial question of Von C helped me understand what is going on: when your rebase, the committer's timestamp changes, but not the author's timestamp, which suddenly all makes sense. So my question was actually not precise enough. The answer is that rebase actually doesn't change the author's timestamps (you don't need to do anything for that), which suits me perfectly.

  • How to append to a log file in powershell?

    - by Mark Allison
    Hi there, I am doing some parallel SQL Server 2005 database restores in powershell. The way I have done it is to use cmd.exe and start so that powershell doesn't wait for it to complete. What I need to do is to pipe the output into a log file with append. If I use Add-Content, then powershell waits, which is not what I want. My code snippet is foreach ($line in $database_list) { <snip> # Create logins sqlcmd.exe -S $instance -E -d master -i $loginsFile -o $logFile # Read commands from a temp file and execute them in parallel with sqlcmd.exe cmd.exe /c start "Restoring $database" /D"$pwd" sqlcmd.exe -S $instance -E -d master -i $tempSQLFile -t 0 -o $logFile [void]$logFiles.Add($logFile) } The problem is that sqlcmd.exe -o overwrites. I've tried doing this to append: cmd.exe /c start "Restoring $database" /D"$pwd" sqlcmd.exe -S $instance -E -d master -i $tempSQLFile -t 0 >> $logFile But it doesn't work because the output stays in the SQLCMD window and doesn't go to the file. Any suggestions? Thanks, Mark.

  • How to mix Grammar (Rules) & Dictation (Free speech) with SpeechRecognizer in C#

    - by Lee Englestone
    I really like Microsofts latest speech recognition (and SpeechSynthesis) offerings. http://msdn.microsoft.com/en-us/library/ms554855.aspx http://estellasays.blogspot.com/2009/04/speech-recognition-in-cnet.html However I feel like I'm somewhat limited when using grammars. Don't get me wrong grammars are great for telling the speech recognition exactly what words / phrases to look out for, however what if I want it to recognise something i've not given it a heads up about? Or I want to parse a phrase which is half pre-determined command name and half random words? For example.. Scenario A - I say "Google [Oil Spill]" and I want it to open Google with search results for the term in brackets which could be anything. Scenario B - I say "Locate [Manchester]" and I want it to search for Manchester in Google Maps or anything else non pre-determined I want it to know that 'Google' and 'Locate' are commands and what comes after it are parameters (and could be anything). Question : Does anyone know how to mix the use of pre-determined grammars (words the speech recognition should recognise) and words not in its pre-determined grammar? Code fragments.. using System.Speech.Recognition; ... ... SpeechRecognizer rec = new SpeechRecognizer(); rec.SpeechRecognized += rec_SpeechRecognized; var c = new Choices(); c.Add("search"); var gb = new GrammarBuilder(c); var g = new Grammar(gb); rec.LoadGrammar(g); rec.Enabled = true; ... ... void rec_SpeechRecognized(object sender, SpeechRecognizedEventArgs e) { if (e.Result.Text == "search") { string query = "How can I get a word not defined in Grammar recognised and passed into here!"; launchGoogle(query); } } ... ... private void launchGoogle(string term) { Process.Start("IEXPLORE", "google.com?q=" + term); }

  • Messages not forwarded to error queue when exception is thrown in handler (it works on my machine)

    - by darthjit
    e are using NServicebus 4.0.5 with sql server(sql server 2012) as transport. When the handler throws an exception, NSB does not retry or move the message to the error queue. Successful messages make it to the audit queue but the failed/errored ones don't! . Interestingly, all this works on our local machines(windows 7 ,sql server localdb) but not on windows server 2012 (sql server 2012). Here is the config info on the subscriber: <add name="NServiceBus/Transport" connectionString="Data Source=xxx;Initial Catalog=NServiceBus;Integrated Security=SSPI;Enlist=false;" /> <add name="NServiceBus/Persistence" connectionString="Data Source=xxx;Initial Catalog=NServiceBus;Integrated Security=SSPI;Enlist=false;" /> <MessageForwardingInCaseOfFaultConfig ErrorQueue="error" /> <UnicastBusConfig ForwardReceivedMessagesTo="audit"> <MessageEndpointMappings> <add Assembly="Services.Section.Messages" Endpoint= "Services.ACL.Worker" /> </MessageEndpointMappings> </UnicastBusConfig> And in code it is configured as follows: public class EndpointConfig : IConfigureThisEndpoint, AsA_Server, IWantCustomInitialization { public void Init() { IContainer container = ContainerInstanceProvider. GetContainerInstance(); Configure .Transactions.Enable(); Configure.With() .AutofacBuilder(container) .UseTransport<SqlServer>() .Log4Net() //.Serialization.Json() .UseNHibernateSubscriptionPersister() .UseNHibernateTimeoutPersister() .MessageForwardingInCaseOfFault() .RijndaelEncryptionService() .DefiningCommandsAs(type => type.Namespace != null &&type .Namespace.EndsWith("Commands")) .DefiningEventsAs(type => type.Namespace != null &&type .Namespace.EndsWith("Events")) .UnicastBus(); } } Any ideas on how to fix this? here is the log info (there is a lot there, search for error to see the relevant parts) https://gist.github.com/ranji/7378249

  • SQL using sum to count results of multiple subqueries

    - by asdas
    I have a table with 2 columns: integer and var char. I am given only the integer values but need to do work on the var char (string) values. Given an integer, and a list of other integers (no overlap), I want to find the string for that single integer. Then I want to take that string and do the INSTR command with that string, and all the other strings for all the other integers. Then I want the sum of all the INSTR so the result is one number. So lets say I have int x, and list y=[y0, y1, y2]. I want to do 3 INSTR commands like SUM(INSTR(string for x, string for y0), INSTR(string for x, string for y1), INSTR(string for x, string for y2)) I think im going in the wrong direction, this is what I have. Im not good with sub queries. SELECT SUM ( SELECT INSTR ( SELECT string FROM pages WHERE int=? LIMIT 1, ( SELECT string FROM pages WHERE id=? OR id=? OR id=? LIMIT 3 ) ) )

  • Like posts over Facebook graph api

    - by Sima
    HI! I have little problem with facebook PHP SDK..I want to like a post, or something else via facebook PHP SDK..I am doing this code, I think it should be right, but  apparently it's not working..The given error code is, the PHP SDK dont know this kind of POST request(the generated link is definitely alright). What I have seen on Facebook Developers page is about the same..There is an example of Curl command, and I the PHP SDK is doing this requests over Curl (propably). $this->getFacebook()->api("/"+$id+"/likes", 'post'); This is what I am using in my code and it's not working(Facebook API Exception unsupported post request). Maybe, I have bad syntax in my code, but, for example, when I want to post a status to my Profile, it's working..Another cause which confused me, was when I tried to fetch these data over Graph api(on the documentation page is written, I should use address like graph.facebook.com/POST_ID/likes)... You can comment on or like a post by posting to https://graph.facebook.com/POST_ID/comments and https://graph.facebook.com/POST_ID/likes,respectively: curl -F 'access_token=...' \ https://graph.facebook.com/313449204401/likes <=this is from facebook documentation And all these requests or commands(liking ones, comments have I not yet tried) are putting me back a JSON array which contents any already existing likes, but my like is nowhere. Does anyone know what to do?How to like a post from PHP..There are other SKDs like FQL, but I haven't any knowlegde with it, so I like rather to use the standard PHP SDK(but if is there some possibility how to call for example FQL from PHP SDK, here I am:)) Please help..

  • What type of web service should I put together?

    - by Jake
    I want to write a web service using Visual Studio. The service needs to support some type of authentication, and should be able to receive commands via simple HTTP GET requests. The input would only be a method call with some parameters, and the responses will be simple status/error codes. My instinct would be to go with an ASP.NET Web Service, but this isn't an option in C# 4.0 and it makes me wonder if I should be using something that's more up-to-date. I've looked into WCF, but it seems like this requires a running application on the client-side - is there a way to query a WCF host by just accessing a URL? The authentication is also an important piece. Developing my own little authentication system seems like a bad idea - I've read that it's too easy to mess up. What would be the standard way of authenticating with a web service like this? I'd love to look up all of the specifics on this and learn it myself, but I really don't even know where to begin. Some direction would be greatly appreciated!

  • PHP Notice: Undefined property: stdClass:

    - by 4D
    I've got an array coming back from a Flash app created in Flash Builder 4. I have a service setup that queries and brings data back from the DB successfully, however the Update script is generating the Undefined Property errors. I'm still learning both PHP and Flash Builder, and don't fully understand what the $this- commands do. If anyone can suggest where this script is going wrong, it is basically just generated by Flash Builder and is not something I've developed myself, I would appreciate it? Also if someone can explain $this- to me that would be awesome too? I've seen them before, but then I've seen scripts doing the same thing that do not use them, so is this an old way of doing things? Really appreciate any input anyone can give. public function updateItem($item) { // TODO Auto-generated method stub // Update an existing record in the database and return the item // Sample code \' $this->connect(); $sql = "UPDATE tbltrust SET inst_code = '$item->inst_code', trust_name = '$item->trust_name', trust_code = '$item->trust_code' WHERE trust_key = '$item->trust_key'"; mysqli_query($this->connection, $sql) or die('Query failed: ' . mysqli_error($this->connection)); mysqli_close($this->connection); }

  • Altering an embedded truetype font so it will be useable by Windows GDI

    - by Ritsaert Hornstra
    I am trying to render PDF content to a GDI device context (a 24bit bitmap to be exact). Parsing the PDF stream into PDF objects and rendering the PDF commands from the content dictionary works well, inclduing font rendering. Embedded fonts are decompressed from their FontFile streams and "loaded" using AddFontMemResourceEx. Now some embedded fonts remove some TrueType tables that are needed by GDI, like the NAME table. Because of this, I tried to modify the font by parsing the TrueType subset font into it's tables and modify those tables that have data missing / missing tables are regenerated with as correct information as possible. I use the Microsoft Font Validator tool to see how "correct" the generated font is. I still get a few errors, like for the maxp table the max values are usually too large (it is a subset) or The xAvgCharWidth field does not equal the calculated value of the OS/2 table is not correct but this does not stop other embedded fonts to be useable.The fonts embedded using PDFCreator are the ones that are problematic. Question: - How can I determine what I need to change to the font file in order for GDI to be able to use it? - Are there any other font validation tools that might give me insight into what is still wrong with the fontfile? If needed: I can make an original fontfile and an altered fontfile available for download somewhere.

  • select failing with C program but not shell

    - by Gary
    So I have a parent and child process, and the parent can read output from the child and send to the input of the child. So far, everything has been working fine with shell scripts, testing commands which input and output data. I just tested with a simple C program and couldn't get it to work. Here's the C program: #include <stdio.h> int main( void ) { char stuff[80]; printf("Enter some stuff:\n"); scanf("%s", stuff); return 0; } The problem with with the C program is that my select fails to read from the child fd and hence the program cannot finish. Here's the bit that does the select.. //wait till child is ready fd_set set; struct timeval timeout; FD_ZERO( &set ); // initialize fd set FD_SET( PARENT_READ, &set ); // add child in to set timeout.tv_sec = 3; timeout.tv_usec = 0; int r = select(FD_SETSIZE, &set, NULL, NULL, &timeout); if( r < 1 ) { // we didn't get any input exit(1); } Does anyone have any idea why this would happen with the C program and not a shell one? Thanks!

  • Turning on multiple result sets in an ODBC connection to SQL Server

    - by David Griffiths
    I have an application that originally needed to connect to Sybase (via ODBC), but I've needed to add the ability to connect to SQL Server as well. As ODBC should be able to handle both, I thought I was in a good position. Unfort, SQL Server will not let me, by default, nest ODBC commands and ODBCDataReaders - it complains the connection is busy. I know that I had to specify that multiple active result sets (MARS) were allowed in similar circumstances when connecting to SQL Server via a native driver, so I thought it wouldn't be an issue. The DSN wizard has no entr y when creating a SystemDSN. Some people have provided registry hacks to get around this, but this did not work (add a MARS_Connection with a value of Yes to HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI\system-dsn-name). Another suggestion was to create a file-dsn, and add "MARS_Connection=YES" to that. Didn't work. Finally, a DSN-less connection string. I've tried this one (using MultipleActiveResultSets - same variable as a Sql Server connection would use), "Driver={SQL Native Client};Server=xxx.xxx.xxx.xxx;Database=someDB;Uid=u;Pwd=p;MultipleActiveResultSets=True;" and this one: "Driver={SQL Native Client};Server=192.168.75.33\\ARIA;Database=Aria;Uid=sa;Pwd=service;MARS_Connection=YES;" I have checked the various connection-string sites - they all suggest what I've already tried.

  • Assign sage variable values into R objects via sagetex and Sweave

    - by sheed03
    I am writing a short Sweave document that outputs into a Beamer presentation, in which I am using the sagetex package to solve an equation for two parameters in the beta binomial distribution, and I need to assign the parameter values into the R session so I can do additional processing on those values. The following code excerpt shows how I am interacting with sage: <<echo=false,results=hide>>= mean.raw <- c(5, 3.5, 2) theta <- 0.5 var.raw <- mean.raw + ((mean.raw^2)/theta) @ \begin{frame}[fragile] \frametitle{Test of Sage 2} \begin{sagesilent} var('a1, b1, a2, b2, a3, b3') eqn1 = [1000*a1/(a1+b1)==\Sexpr{mean.raw[1]}, ((1000*a1*b1)*(1000+a1+b1))/((a1+b1)^2*(a1+b1+1))==\Sexpr{var.raw[1]}] eqn2 = [1000*a2/(a2+b2)==\Sexpr{mean.raw[2]}, ((1000*a2*b2)*(1000+a2+b2))/((a2+b2)^2*(a2+b2+1))==\Sexpr{var.raw[2]}] eqn3 = [1000*a3/(a3+b3)==\Sexpr{mean.raw[3]}, ((1000*a3*b3)*(1000+a3+b3))/((a3+b3)^2*(a3+b3+1))==\Sexpr{var.raw[3]}] s1 = solve(eqn1, a1,b1) s2 = solve(eqn2, a2,b2) s3 = solve(eqn3, a3,b3) \end{sagesilent} Solutions of Beta Binomial Parameters: \begin{itemize} \item $\sage{s1[0]}$ \item $\sage{s2[0]}$ \item $\sage{s3[0]}$ \end{itemize} \end{frame} Everything compiles just fine, and in that slide I am able to see the solutions to the three equations respective parameters in that itemized list (for example the first item in the itemized list from that beamer slide is outputted as [a1=(328/667), b1=(65272/667)] (I am not able to post an image of the beamer slide but I hope you get the idea). I would like to save the parameter values a1,b1,a2,b2,a3,b3 into R objects so that I can use them in simulations. I cannot find any documentation in the sagetex package on how to save output from sage commands into variables for use with other programs (in this case R). Any suggestions on how to get these values into R?

  • Carriage Return\Line feed in Java

    - by Manu
    Guys, i have created text file in unix enviroment using java code. For writing the text file i am using java.io.FileWriter and BufferedWriter. and for newline after each row i am using bw.newLine() method. (where bw is object of BufferedWriter ) and sending that text file by attaching in mail from unix environment itself (automated that using unix commands). My issue is, after i download the text file from mail in windows system, if i opened that text file the data's are not properly aligned. newline() character is not working i think so. I want same text file alignment as it is in unix environment, if i opened the text file in windows environment also. How to resolve the problem.Please help ASAP. Thanks for your help in advance. pasting my java code here for your reference..(running java code in unix environment) File f = new File(strFileGenLoc); BufferedWriter bw = new BufferedWriter(new FileWriter(f, false)); rs = stmt.executeQuery("select * from jpdata"); while ( rs.next() ) { bw.write(rs.getString(1)==null? "":rs.getString(1)); bw.newLine(); }

  • Issues with intellisense, references, and builds in Visual Studio 2008

    - by goober
    Hoping you can help me -- the strangest thing seems to have happened with my VS install. System config: Windows 7 Pro x64, Visual Studio 2008 SP1, C#, ASP.NET 3.5. I have two web site projects in a solution. I am referencing NUnit / NHibernate (did this by right-clicking on the project and selecting "Add Reference". I've done this for several projects in the past). Things were working fine but recently stopped working and I can't figure out why. Intellisense completely disappears for any files in my App_Code directory, and none of the references are recognized (they are recognized by any file in the root directory of the web site project. Additionally, pretty simple commands like the following (in Page_Load) fail (assume TextBox1 is definitely an element on the page): if (Page.IsPostBack) { str test1; test1 = TextBox1.Text; } It says that all the page elements are null or that it can't access them. At first I thought it was me, but due to the combination of issues, it seems to be Visual Studio itself. I've tried clearing the temp directories & rebuilding the solution. I've also tried tools -- options -- text editor settings to ensure intellisense is turned on. I'd appreciate any help you can give!

  • Memeory Leak in Windows Page file when calling a shell command

    - by Arno
    I have an issue on our Windows 2003 x64 Build Server when invoking shell commands from a script. Each call causes a "memory leak" in the page file so it grows quite rapidly until it reaches the maximum and the machine stops working. I can reproduce the problem very nicely by running a perl script like for ($count=1; $count<5000; $count++) { system "echo huhu"; } It is independent of he scripting language as the same happens with lua: for i=1,5000 do os.execute("echo huhu") end I found somebody describing the same issue with php at http://www.issociate.de/board/post/454835/Memory_leak_occurs_when_exec%28%29_function_is_used_on_Windows_platform.html His solution: Firewall/Virus Scanner does not apply, neither are running on the machine. We can also reproduce the issue on other Developer Machines running XP 64, but not on XP 32 Bit. I also found an article describing a leak situation in page file at http://www.programfragment.com/ The guilty guy for the allocation is C:\WINDOWS\System32\svchost.exe -k netsvcs which runs all the basic Windows services. Does anybody know the issue and how to resolve it ?
