• Can anyone get this project to work? (EasyHook)

  - by Tom

  Hi, i'm trying to 'load' the following project into visual studio 2010 but im getting errors about dynamic link libraries not being found. I have manually referenced them but it doesnt like them. The project is: http://www.codeproject.com/KB/DLL/EasyHook64.aspx 2nd link down (EasyHook_2.5_Beta_Source_Code), and the project im wishing to load is EasyHook_2.5_Beta_Source_Code\Examples\ProcessMonitor The two dlls plus 1 executable i need are found in the first link (EasyHook 2.5 beta binaries) and named EasyHook.dll, EasyHook32.dll and EasyHook32svc.exe I've been trying to do this all night but i wonder whether its because im using VS2010 and .NET 4.0?? I'd be so appreciative if someone could have a go themselves just to see if its my setup or they get errors to. The error i get is: Unable to load DLL 'EasyHook32.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

• What can cause legit MySql INSERT INTO command to fail?

  - by Makis

  I can't figure out what's causing my INSERT INTO's to fail to certain table in MySql. I can manage them to other tables. The table looks like: CREATE TABLE IF NOT EXISTS `Match` ( `id` int(11) NOT NULL AUTO_INCREMENT, `match_no` int(11) NOT NULL, `season` int(11) NOT NULL, `hometeam` int(11) NOT NULL, `awayteam` int(11) NOT NULL, PRIMARY KEY (`id`), KEY `match_no` (`match_no`), KEY `season` (`season`), KEY `hometeam` (`hometeam`), KEY `awayteam` (`awayteam`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ; And the command is INSERT INTO Match (`match_no`, `season`, `hometeam`, `awaytem`) VALUES (1, 1, 2, 3) All I get is: 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Match (match_no, season, hometeam, awaytem) VALUES (1, 1, 2, 3)' at line 1 I have checked the manual and half-a-dozen examples from the web and whatnought and tried all sorts of changes to the syntax in case there is some MySql specific oddity, but nothing seems to work.

• Replace string in one file with contents of a second file

  - by jag7720

  I have two files: fileA: date >> /root/kvno.out kvno serverXXX\$ >> /root/kvno.out fileB: foobar I need to create a new file, fileC, with the same contents as fileA, except with the string XXX being replaced with the contents of fileB: date >> /root/kvno.out kvno serverfoobar\$ >> /root/kvno.out I'd like to do this using sed. I tried some of the examples I found but I only get the contents of fileB in fileC.

• Using transactions with ADO.NET Data Adapters.

  - by Ergwun

  Scenario: I want to let multiple (2 to 20, probably) server applications use a single database using ADO.NET. I want individual applications to be able to take ownership of sets of records in the database, hold them in memory (for speed) in DataSets, respond to client requests on the data, perform updates, and prevent other applications from updating those records until ownership has been relinquished. I'm new to ADO.NET, but it seems like this should be possible using transactions with Data Adapters (ADO.NET disconnected layer). Question part 1: Is that the right way to try and do this? Question part 2: If that is the right way, can anyone point me at any tutorials or examples of this kind of approach (in C#)? Question part 3: If I want to be able to take ownership of individual records and release them independently, am I going to need a separate transaction for each record, and by extension a separate DataAdapter and DataSet to hold each record, or is there a better way to do that? Each application will likely hold ownership of thousands of records simultaneously.

• Java Inter Application Form Communication Observer Pattern

  - by ikurtz

  Observer pattern? Where do i get examples of this in Java (i know google but was hoping for some personal insight also.) On to a proper explanation of my issue: i have 3 forms/windows. "board" is the main form that loads as the application. "chat" is where the text chat takes place. "network" is where network connection is established. i have the game (connect4) working locally and i would like to implement a networked version of it also. my idea is maybe it is related to Observer pattern to have a thread (or something) monitoring network state during runtime and update the chat and board forms of the current network status as well as delivering received data from the network. are my ideas valid? or how should i go about establishing network and network status updates throughout the application? thank you for your input.

• Proper way of utilizing gearman with my php application.

  - by luckytaxi

  For now I just want to use Gearman for background processing. For example, I need to email a recipient that they have a private message waiting for them once the sender submits their message into the DB. I assume I can run the worker/client and server on my primary server but I have no problems offloading some of the tasks to a different web server. Anyways, my question is how do I handle multiple "functions?" Let's say I need a job that handles the email portion and a job to handle image manipulation. Can I have multiple functions in the worker? I've followed a couple of examples I found online but each example only shows one function being initialized. Do I have to start up multiple "workers" to handle multiple functions?

• Why is there so much "magic" in Perl?

  - by eugene y

  I'm looking through perlop and perlsub pages of the Perl manual. There are many references about "magic" and "magical" here (just search any of them for the "magic"). I wonder why is Perl so rich in them. Some examples: print ++($foo = 'zz') # prints 'aaa' printf "%d: %s", $! = 1, $! # prints '1: Operation not permitted' use warnings; my $i; print $i++ # no warning for uninitialized value while (my $line = <FH>) { ... } # $line is actually tested for definedness

• Java applet - access denied to file on same web server

  - by me_here

  I've written a simple Java applet to generate a technical image based upon some data in a CSV file. I'm passing in the CSV file as a parameter to the applet: <applet code = "assaymap.AssayMapApplet" archive = "http://localhost/applet_test/AssayMap.jar" height="600px" width="800px"> <param name="csvFile" value="http://localhost/applet_test/test.csv"> </applet> As far as I understood applet security restrictions, an applet should be able to read data from the host they're on. These applets here http://www.jalview.org/examples/applets.html are using the same approach of passing in a text data file as a parameter. So I'm not sure why my own applet isn't working. The error message I get thrown is: Error with processing the CSV data. java.security.AccessControlException: access denied (java.io.FilePermission http:\localhost\applet_test\test.csv read)

• Why does PowerShell fail to build my .net solutions? ("file is being used by another process")

  - by urig

  I've written a PowerShell script to build several .net solutions one after the other. It simply makes several calls to csc.exe to build the .sln files. Almost every time I run the script one of the solutions fails to build and CSC.exe reports: error CS1606: Assembly signing failed; output may not be signed -- The process cannot access the file because it is being used by another process. This happens even though I've closed all instances of Visual Studio holding these solutions and I've none of their exes running on mu machine. A similar batch file that I've written works just fine. It's only PowerShell that complains about the file being used by another process. How can avoid having this happen? Are there any better examples out there of building .net solutions through PowerShell?

• Cheat sheet exhibiting bash shell stdout/stderr redirection behavior

  - by SetJmp

  Is there a good cheat sheet demonstrating the many uses of BASH shell redirection? I would love to give such a thing to my students. Some examples I'd like to see covered: cmd > output_file.txt #redirect stdout to output_file.txt cmd 2> output_file.txt #redirect stderr to output_file.txt cmd >& outpout_file.txt #redirect both stderr and stdout to output_file.txt cmd1 | cmd2 #pipe cmd1 stdout to cmd2's stdin cmd1 2>&1 | cmd2 #pipe cmd1 stdout and stderr to cmd2's stdin cmd1 | tee result.txt #print cmd1's stdout to screen and also write to result.txt cmd1 2>&1 | tee result.txt #print stdout,stderr to screen while writing to result.txt (or we could just make this a community wiki and enumerate such things here) Thanks!

• How do I invoke my custom settings provider?

  - by joebeazelman

  I need to specify a different location for my settings file. After many long hours of searching, I found out that I have to write my own SettingsProvider. I succeeded in creating one which allows me to specify a path for settings file via its constructor. Programatically, I can contruct it like this: var mycustomprovider = new CustomSettingsProvider(path); The problem I am having is that there's no way to invoke my custom provider. I can decorate the VS 2008 generated setting file with the following attribute: [SettingsProvider(typeof(CustomSettingProviders.CustomSettingsProvider))] internal sealed partial class Settings { } However, the attribute doesn't allow me to construct the object with a path. Also, I want to be able to set the SettingsProvider programmatically so that I can pass in any path I want at runtime and save my settings. The examples I've seen on the net have never mentioned how to use a invoke a SettingsProvider programmatically.

• Programming tests: are they relevant?

  - by BlackVoid

  Do online programming tests have any value (except for providing an evidence to potential employers) in terms of evaluating your knowledge, or a they too broad or too narrow in general? For examples, brainbench.com and similar websites. From my experience I have never found myself scoring particularly high, although I have many years of commercial experience and is doing great at work. These tests mostly refer to things I have never worked with (WebForms or ADO .Net, who works with ADO .Net directly anyway?), yet these tests claim to be C# tests. If you were hiring a programmer, would you consider online tests as an evidence of real skill?

• T-Sql SPROC - Parse C# Datatable to XML in Database (SQL Server 2005)

  - by Goober

  Scenario I've got an application written in C# that needs to dump some data every minute to a database. Because its not me that has written the spec, I have been told to store the data as XML in the SQL Server database and NOT TO USE the "bulk upload" feature. Essentially I just wanted to have a single stored procedure that would take XML (that I would produce from my datatable) and insert it into the database.....and do this every minute. Current Situation I've heard about the use of "Sp_xml_preparedocument" but I'm struggling to understand most of the examples that I've seen (My XML is far narrower than my C Sharp ability). Question I would really appreciate someone either pointing me in the direction of a worthwhile tutorial or helping explain things. EDIT - Using (SQL Server 2005)

• Issue reading packets from a pcap file. dpkt module. What gives?

  - by Chris

  I am running the following test script to try to read packets from a sample .pcap file I have downloaded. It won't seem to run. I have all of the modules, but no examples seem to be running. import socket import dpkt import sys pcapReader = dpkt.pcap.Reader(file("test1.pcap", "rb")) for ts, data in pcapReader: ether = dpkt.ethernet.Ethernet(data) if ether.type != dpkt.ethernet.ETH_TYPE_IP: raise ip = ether.data src = socket.inet_ntoa(ip.src) dst = socket.inet_ntoa(ip.dst) print "%s -> %s" % (src, dst) For some reason, this is not being interpreted properly. When running it, I get KeyError: 138 module body in test.py at line 4 function __init__ in pcap.py at line 105 Program exited. Why is this? What's wrong?

• Substring and its reverse in a string

  - by christa

  My professor was talking about this in a Dynamic programming class and asked us to think over it. She gave us some examples as well. Given a string, we were to find the longest continuous subsequence whose reverse is also a subsequence present in the given string. Example: INPUT: pqrstuvtsrv OUTPUT: i=3, k=2 rst -> tsr (rst found first at i=3 and for 2 more positions) INPUT: mpqrsrqp OUTPUT: i=2, k=6 pqrsrqp in reverse INPUT: mmpqssss OUTPUT: i=5, k=3 I thought of putting the string and its reverse into 2 different arrays and comparing character by character. But I'm sure this is not the best way to do it. Any suggestions as to what could be the most efficient ?

• rdoc and the "--accessor" option

  - by Brian Ploetz

  rdoc --help says: --accessor, -A accessorname[,..] comma separated list of additional class methods that should be treated like 'attr_reader' and friends. Option may be repeated. Each accessorname may have '=text' appended, in which case that text appears where the r/w/rw appears for normal accessors. Does anyone have any working examples of doing this (both the accessor method definition and the rdoc command invocation)? No matter what combination I try, my accessors will not show up in the RDoc output. Thanks.

• Which full-text search package should I use for SQLite3?

  - by Benjamin Pollack

  SQLite3 appears to come with three different full-text search engines, called FTS1, FTS2, and FTS3. The documentation available on the website mentions that FTS1 is stable, FTS2 is in development, and that you should use FTS2. Examples I find online use FTS3, which is in CVS, and not documented versus FTS2. None of the full-text search engines come with the amalgamated source, as near as I can tell. So, my question: which of these three engines, if any, should I use for full-text indexing in SQLite? Or should I simply use a third-party tool like Sphinx, or a custom solution in Lucene, instead?

• Python: Why can't I use `super` on a class?

  - by cool-RR

  Why can't I use super to get a method of a class's superclass? Example: Python 3.1.3 >>> class A(object): ... def my_method(self): pass >>> class B(A): ... def my_method(self): pass >>> super(B).my_method Traceback (most recent call last): File "<pyshell#2>", line 1, in <module> super(B).my_method AttributeError: 'super' object has no attribute 'my_method' (Of course this is a trivial case where I could just do A.my_method, but I needed this for a case of diamond-inheritance.) According to super's documentation, it seems like what I want should be possible. This is super's documentation: (Emphasis mine) super() - same as super(__class__, <first argument>) super(type) - unbound super object super(type, obj) - bound super object; requires isinstance(obj, type) super(type, type2) - bound super object; requires issubclass(type2, type) [non-relevant examples redacted]

• ASP/NET MVC: Test Controllers w/Sessions? Mocking?

  - by Codewerks

  I read some of the answers on here re: testing views and controllers, and mocking, but I still can't figure out how to test an ASP.NET MVC controller that reads and sets Session values (or any other context based variables.) How do I provide a (Session) context for my test methods? Is mocking the answer? Anybody have examples? Basically, I'd like to fake a session before I call the controller method and have the controller use that session. Any ideas?

• Get foreign key in external content type to show up in list view

  - by Rob

  I have come across blogs about how to setup an external content type (e.g. http://www.dotnetmafia.com/blogs/dotnettipoftheday/archive/2010/02/02/it-s-easy-to-configure-an-external-list-with-business-connectivity-services-bcs-in-sharepoint-foundation-2010.aspx) but I have not seen any examples of what to do when your external SQL DB has foreign keys. For example. I have a database that has orders and customers. An order has one and only one customer and a customer can have many orders. How can I setup external content types in such a way that when in the list view of these external content types, I can jump between and possible lookup values to that other type?

• How to detect if certain characters are at the end of an NSString?

  - by Sheehan Alam

  Let's assume I can have the following strings: "hey @john..." "@john, hello" "@john(hello)" I am tokenizing the string to get every word separated by a space: [myString componentsSeparatedByString:@" "]; My array of tokens now contain: @john... @john, @john(hello) For these cases. How can I make sure only @john is tokenized, while retaining the trailing characters: ... , (hello) Note: I would like to be able to handle all cases of characters at the end of a string. The above are just 3 examples.

• Getting keyboard size from user info in Swift

  - by user3746428

  I have been trying to add some code to move my view up when the keyboard appears, however I am having issues trying to translate the Objective C examples into Swift. I have made some progress but I am stuck on one particular line. These are the two tutorials/questions I have been following: How to move content of UIViewController upwards as Keypad appears using Swift http://www.ioscreator.com/tutorials/move-view-when-keyboard-appears Here is the code I currently have: override func viewWillAppear(animated: Bool) { NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillShow:", name: UIKeyboardWillShowNotification, object: nil) NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillHide:", name: UIKeyboardWillHideNotification, object: nil) } override func viewWillDisappear(animated: Bool) { NSNotificationCenter.defaultCenter().removeObserver(self) } func keyboardWillShow(notification: NSNotification) { var keyboardSize = notification.userInfo(valueForKey(UIKeyboardFrameBeginUserInfoKey)) UIEdgeInsets(top: 0, left: 0, bottom: keyboardSize.height, right: 0) let frame = self.budgetEntryView.frame frame.origin.y = frame.origin.y - keyboardSize self.budgetEntryView.frame = frame } func keyboardWillHide(notification: NSNotification) { // } At the moment I am getting an error on this line: var keyboardSize = notification.userInfo(valueForKey(UIKeyboardFrameBeginUserInfoKey)) If someone could let me know what this line of code should be, I should manage to figure out the rest myself.

• Set a OGG in raw folder as Ringtone/Notification?

  - by YaW

  Hi, I have some ogg audios in my raw folder and I'm trying to set one of them as a Ringtone (or Notification, Alarm... whatever). I've been looking at the source code of RingDroid and I can see how is this done using the ContentValues and MediaStore, but in all the examples I've seen, the audio files is in the SDCard. Is it possible to set the ringtone directly from the raw folder? If not, how can I make a copy of the raw file to a folder in the SD? Thanks in advance.

• Programmatically clean Word generated HTML while preserving styles?

  - by GeReV

  In my current company, we have this decade old... let's call it a "Hello World" application. While wanting to create a newer version of it, we also want to preserve older entries. These older entries contain hideous Word generated HTML which was never filtered before. If and when we move to a newer system, I'd generally prefer to have that HTML cleaned and filtered in order to have the site comply with HTML standards as much as possible. However, just cleaning that code like Jeff Atwood described in his blog or in any other way I know of would also ruin the style and formatting. Now, that just might cause our users to revolt and then all hell will break loose... Not a very good idea. Question is -- can Word's HTML be cleaned while preserving basic formatting? (e.g: coloring, italicized, bold text and so on) Preferably using publicly available code or library, such as HTML Tidy, examples in C# would be much appreciated. Thanks!
