• SQL Server 2008 error message from stored procedure

  - by George2

  Hello everyone, I am using SQL Server 2008 Enterprise. When we met with such error message from stored procedure, Message 1205, Level 13, State 52, the process Pr_FooV2, Line 9 Services (Process ID 111) and another process is deadlock in the lock | communication buffer resources, and has been chosen as the deadlock victim. Rerun the transaction. I am wondering whether such messages are stored in log files? I searched log folder of my SQL Server 2008 installation root (in my environment, it is C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Log), but can not find such files. thanks in advance, George

• C: theory on how to extract files from an archived file

  - by donok

  In C I have created a program which can archive multiple files into an archive file via the command line. e.g. $echo 'file1/2' > file1/2.txt $./archive file1.txt file2.txt arhivedfile $cat archivedfile file1 file2 How do I create a process so that in my archivedfile I have: header file1 end header file2 end They are all stored in the archive file one after another after another. I know that perhaps a header file is needed(containing filename, size of filename, start and end of file) for extracting these files back out into their original form, but how would I go about doing this. I am stuck on where and how to start. Please could someone help me on some logic as to how to approach extracting files back out of an archived file.

• C# Console Application - Odd behaviour - char '\a'

  - by KHT

  After extensive debugging of an application, I noticed the console window would hang when searching text for the char '\a'. The goal is to strip out characters from a file. The console window would always hang upon exiting the program, and it would make it to the last statement of main. I removed the '\a' from the switch statement and the console application does not hang anymore. Any idea why? I still need to strip out the char '\a', but cannot get the application to work without hanging. switch (c) { case '\t': //Horizontal Tab case '\v': //Vertical Tab case '\n': //Newline case '\f': //Form feed case '\r': //carriage return case '\b': //Backspace case '\x7f': //delete character case '\x99': //TM Trademark case '\a': //Bell Alert **REMOVED THIS** return true; }

• How do I write a Guice Provider that doesn't explicitly create objects?

  - by ripper234

  Say I have a ClassWithManyDependencies. I want to write a Guice Provider for this class, in order to create a fresh instance of the class several times in my program (another class will depend on this Provider and use it at several points to create new instances). One way to achieve this is by having the Provider depend on all the dependencies of ClassWithManyDependencies. This is quite ugly. Is there a better way to achieve this? Note - I certainly don't want the Provider to depend on the injector. Another option I considered is having ClassWithManyDependencies and ClassWithManyDependenciesProvider extend the same base class, but it's butt ugly.

• python: creating a list inside a dictionary

  - by user1871081

  I just started using python and I'm trying to create a program that will read a file that looks like this: AAA x 111 AAB x 111 AAA x 112 AAC x 123 ... the file is 50 lines long and I'm trying to make the letters into keys in a dictionary and the numbers lists that correspond with the keys. I want the output to look like this: {AAA: ['111', '112'], AAB: ['111'], AAC: [123], ...} This is what I've tried file = open("filename.txt", "r") readline = file.readline().rstrip() while readline!= "": list = [] list = readline.split(" ") j = list.index("x") k = list[0:j] v = list[p + 1:] d = {} if k in d == False d[k] = [] d[k].append(v) else d[k].append(v) readline = file.readline().rstrip() I keep getting syntax errors on my if statement and I can't figure out what I've done wrong.

• ruby confusing -- local variable or instance_method ?

  - by boblu

  I have the following program. module C def self.included(base) base.extend(ClassMethods) end module ClassMethods def test_for class_eval <<-DEFINECLASSMETHODS def self.my_method(param_a) puts "SELF is: #{self.inspect}" puts param_a puts "#{param_a}" end DEFINECLASSMETHODS end end end class A include C end class B < A test_for end when I run B.new.my_method("aaa"), I got this error NameError: undefined local variable or method `param_a' for B:Class I am quite confused. I define param_a as a local variable in class method my_method, puts param_a runs good, and will output the "aaa". however, puts "#{param_a}" output that error. why? Can anyone explain this?

• What is the best way to make a game timer in Actionscript 3?

  - by Nuthman

  I have built an online game system that depends on a timer that records how long it took a player to complete a challenge. It needs to be accurate to the millisecond. Their time is stored in a SQL database. The problem is that when I use the Timer class, some players are ending up getting scores in the database of less than a second. (which is impossible, as most challenges would take at least 11 seconds to complete even in a perfect situation.) What I have found is that if a player has too many browser windows open, and/or a slow computer, the flash game slows down actually affecting the timer speed itself. The timer is 'spinning' on screen so you can physically see the numbers slowing down. It is frustrating that I cannot just open a second thread or do something to allow flash to keep accurate time regardless of whatever else is going on in the program. Any ideas?

• How can I modify the application file of an application that is currently running (on Linux)?

  - by Hach-Que

  I have an application running called AppFS. This application has an ext2 filesystem just attached to the end of the file (it's positioned so that the application binary exists in a 1MB spacing area, followed by the ext2 data). Now I've got FUSE embedded in the program and I've managed to extract the filesystem out of the application data into a temporary file so that FUSE can mount / use it. The problem I have now is writing the temporary file back into the application file. I get "Text file busy" presumably because the application has locked itself and won't let writes occur. Is there a way I can force the file to become unlocked so I can write data to it? (It's important to note that I'm not changing the application binary area - just rewriting the ext2 component.) It needs to be unlocked without requiring root permissions (unlocked by the same user who started the application).

• Why do so many mathematicians format code so poorly? [closed]

  - by marcog

  I have done a fair amount of programming together with mathematicians. Now I am even teaching some high school kids coming from a mathematics background how to program. Most of these people format their code so hideously it's hard to believe. I've even worked with and taught mathematicians who will fight the auto-indenter! Why is this so common amongst mathematicians? BTW, this is one reason I have started teaching Python. Yet still they find ways other than indentation to produce whacked coding styles!

• How to manually close connection in BaseHTTPServer?

  - by user1657188

  I have a script that sends a request to an HTTP server. HTTP server script (snippet): ... class MyHandler(BaseHTTPServer.BaseHTTPRequestHandler): def do_GET(sa): pdict = cgi.parse_header(sa.headers.getheader('referer')) q = pdict[0] q = urllib.unquote(q) if q == "enternetixplorer" # basically just ignore this, doesn't have to do with the question sa.wfile.write("blah blah blah") # now restart server httpd.server_close() python = sys.executable os.execl(python, python, * sys.argv) ... The "blah blah blah" is sent back, but the connection does not seem to close, and my script is waiting forever until I abort the server. (My thought is BaseHTTPServer automatically closes connection when the last part in "do_GET()" is computed, but I prevent this by restarting the script.) If I'm right, how do I close the connection? If not, what else might be the problem? Edit: The server script HAS to restart the entire program.

• vb express / visual studio - is it possible to run / debug one form only in a multi form application

  - by Luay

  hi, I have a vb application consisting of several winForms and code files. Is it possible to run / debug only one form without having to run the whole application? To be more specific, one of the forms in my application is the settings form where the user sets his/her desired options. These options are read/written to an xml file. Is it possible to debug just this one form (and not the whole program) to see if the reading/writing went well, if everything displayed correctly... ? If I am thinking the wrong way about this, could you point me in the right direction? By the way, I am using visual basic express / visual studio.

• A strange issue... No code changes getting reflected.

  - by sachin

  I am using netbeans to develop an applet, i have a piece of code which looked like this: ipAddresss = DEFAULT_IP; System.out.println("portlet.services.hostname:" + ipAddresss); Now I changed it to something like this: ipAddresss = DEFAULT_IP; System.out.println("portlet.services.hostname using default IP Address:" + ipAddresss); But no matter what I do, it sill keep on printing: portlet.services.hostname:null I have tried deleting all .netbeans folder from documents and settings, tried creating new project, but now i am completely baffled by this issue... So, the problem is, no matter what I do, no change is getting reflected when I run the program. Can there be a java applet cache, netbeans cache, i am not sure why...

• FTP .NET Sockets

  - by Jojo

  Hi Everyone, I have an FTP auto downloader program. It downloads new files from a given FTP folder. The application was successful for some FTP folders that i have tested. These folders contain 30 - 50 files. However, when i tried an FTP folder with 150 and 18000 files, i receive this error message: An established connection was aborted by the software in your host machine. My first assumptions will be because of firewalls or anti virus. I don't have administrative access to this computer so I would like to ask if there are other reasons for this before i raise this to our systems dept? Need anyone's help asap. Thanks :)

• directory monitoring

  - by foz1284

  Hi, What is the best way for me to check for new files added to a directory, I dont think the filesystemwatcher would be suitable as this is not an always on service but a method that runs when my program starts up. there are over 20,000 files in the folder structure I am monitoring, at present I am checking each file individually to see if the filepath is in my database table, however this is taking around ten minutes and I would like to speed it up is possible, I can store the date the folder was last checked - is it easy to get all files with createddate last checked date. anyone got any Ideas? Thanks Mark

• how to display CFStringType? Like kABHomeLabel

  - by xiaozi

  I know that NSString and CFString are toll-bridge, they can convert in such a way. CFStringRef cfStr; NSString* anStr=(NSString*)cfStr; however,when I convert string in such a case when dealing addressbook NSString* homeLabel=(NSString*)kABWorkLabel; then homeLabel is "$!!$"; the other pre-defined CFStringRef in the addressbook property is the same. in my program,I want to get both the label and the label item's info. NSString* label=ABMultiValueCopyLabelAtIndex(multi,i); so how to correctly get the string of the label? Thanks!

• string holding text every \n

  - by gcc

  I tried to take input in form of string, specifically: int i=0; char c[50][500]; for(;i<50;++i) scanf("%s",A[i]); The input is x is a website that allows the easy[1] creation and editing of any number of interlinked web pages via a web browser using a simplified markup language or a WYSIWYG text editor. In my program, I want the text to be stored as: A[0]="x is a website that allows the easy[1] creation and editing of any number of interlinked" A[1]=" web pages via a web browser using a simplified markup language or a WYSIWYG text editor." But my code causes the text to be stored as A[0]="is" A[1]="a" A[2]="website" .... What am I doing wrong?

• Loop function works first time, not second time

  - by user1483101

  I'm creating a parsing program to look for certain strings in a a text file and count them. However, I'm having some trouble with one spot. def callbrowse(): filename = tkFileDialog.askopenfilename(filetypes = (("Text files", "*.txt"),("HTML files", ".html;*.htm"),("All files", "*.*"))) print filename try: global filex global writefile filex = open(filename, 'r') print "Success!!" print filename except: print "Failed to open file" ######This returns the correct count only the first time it is run. The next time it ######returns 0. If the browse button is clicked again, then this function returns the ######correct count again. def count_errors(error_name): count = 0 for line in filex: if error_name == "CPU > 79%": stringparse = "Utilization is above" elif error_name == "Stuck touchscreen": stringparse = "Stuck touchscreen" if re.match("(.*)" + "Utilization is above" + "(.*)",line): count = count + 1 return count Thanks for any help. I can't seem to get this to work right.

• How to check that a regular expression fall into infty loop or not?

  - by Sorush Rabiee

  I'm trying to learn and hopefully use regular expression with Qt. I found that some patterns cause handler to fall into loop. for example searching \b\b in a text, never will terminate. and number of these expressions is infinite (\b\b\b,\b\b\b\b and so on). I'd like to determine and control all invalid expressions. Is there an algorithm to distinguish valid and invalid expressions? If not, how can I prevent my program from falling into an infinite loop?

• How does HTTP Analyzer works?

  - by Rampage

  Halo, i am interest in methods, which http analyzer uses to capture data. I would like to write program which saves emails sent via web based clients. The problem is https and HTTP Analyzer solves it, but i dont know how. I got one interesting answer on my question before, but it doesnt reveal as much as i would like to know. Programs like HTTP Analyzer can catch the HTTPS data because they insert themselves in the HTTPS stack. As a result, they get the data after it's generated but before it's being encrypted and put in IP packets. This is highly non-trivial. How it is possible to make? If you have any interesting articles solving this issue, please let me know.

• How to update JLabel in Swing?

  - by Roman

  I am trying to use Swing Timer and I wanted to start from a very simple program. I have a window with text: "You have n seconds", where n changes from 10 to 0 every second. I know how to generate a window with text. And I understand how Timer works (it starts an action periodically). But I cannot figure out how to combing this two things. Should I use that: JLabel label = new JLabel(myMessage); and then with timer I need to update the "myMessage" variable? But I think I need to "force" my window to "update" itself (to display a new value stored in "myMessage").

• What host do I have to bind a listening socket to?

  - by herrturtur

  I used python's socket module and tried to open a listening socket using import socket import sys def getServerSocket(host, port): for r in socket.getaddrinfo(host, port, socket.AF_UNSPEC, socket.SOCK_STREAM, 0, socket.AI_PASSIVE): af, socktype, proto, canonname, sa = r try: s = socket.socket(af, socktype, proto) except socket.error, msg: s = None continue try: s.bind(sa) s.listen(1) except socket.error, msg: s.close() s = None continue break if s is None: print 'could not open socket' sys.exit(1) return s Where host was None and port was 15000. The program would then accept connections, but only from connections on the same machine. What do I have to do to accept connections from the internet?

• Closed Source Java Applications

  - by Paul

  I am taking programming courses and we have been discussing Open Source and having a bit of an argument over the confusion. Just because Java is Open Source, the licensing on developed applications starts at the developer, correct? Someone is arguing about the use of code from a complete program just because "Java is Open Source". If I write a Java application, what are the limitations on how I can distribute it or how someone else can use it? Assume here that I DO NOT want someone having access to my source. Thanks

• multiple threads writting to a same socket problem

  - by alex

  Hi: My program uses sockets for inter-process communication. There is one server listening on a socket port(B) on localhost waiting for a list of TCP clients to connect. And on the other end of the server is another a socket(A) that sends out data to internet. The server is designed to take everything the TCP clients send him and forward to a server on the internet. My question is if two of the TCP clients happened to send data at the same time, is this going to be a problem for the server's outgoing socket(A)? Thanks
