• Using a framework in a PreferencePane

  - by Jonathan

  Hi, i am currently trying to implement a "third party framework" (FeedbackReporter.Framework) into my preferencepane. Unfortunately I am getting the following error all the time when trying to launch my preference pane: 16.05.10 23:13:30 System Preferences[32645] dlopen_preflight failed with dlopen_preflight(/Users/me/Library/PreferencePanes/myPane.prefPane/Contents/MacOS/myPane): Library not loaded: @executable_path/../Frameworks/FeedbackReporter.framework/Versions/A/FeedbackReporter Referenced from: /Users/me/Library/PreferencePanes/myPane.prefPane/Contents/MacOS/myPane Reason: image not found for /Users/me/Library/PreferencePanes/myPane.prefPane As far as I read so far, this problem is probably caused because my prefPane is no actual app, but a "plugin" of "System Settings.app" and thus @executable_path resolves to a path within the bundle of this app, instead of the bundle of my prefpane. But I don't really picked up howto fix this problem. I guess it must be fairly easy since it should be a usual case that people use non-apple-frameworks in PreferencePanes. Thanks for your hints!

• MapPath strange error

  - by Cristian Boariu

  Hi, I have the following code: string path = "~/Others/Muzica/Demo/"+interpret+"_"+album+"/"; CMSUtils.CreateFolder(MapPath(path)); where CreateFolder method is like: public static void CreateFolder(string path) { if (!System.IO.Directory.Exists(path)) { System.IO.Directory.CreateDirectory(path); } } So i create that folder if it does not exists... All works great locally BUT i do not understand why, if i put it on the server it gives: Failed to map the path '/gramma_prod/Others/Muzica/Demo/Vitamina C_De n-ai fi fost Tu /'. at CMSUtils.CreateFolder(MapPath(path)); I have checked if: /gramma_prod/Others/Muzica/Demo/ exists on the server and of course it exists... Does anybody see the problem?

• SQL version control methodology

  - by Tom H.

  There are several questions on SO about version control for SQL and lots of resources on the web, but I can't find something that quite covers what I'm trying to do. First off, I'm talking about a methodology here. I'm familiar with the various source control applications out there and I'm familiar with tools like Red Gate's SQL Compare, etc. and I know how to write an application to check things in and out of my source control system automatically. If there is a tool which would be particularly helpful in providing a whole new methodology or which have a useful and uncommon functionality then great, but for the tasks mentioned above I'm already set. The requirements that I'm trying to meet are: The database schema and look-up table data are versioned DML scripts for data fixes to larger tables are versioned A server can be promoted from version N to version N + X where X may not always be 1 Code isn't duplicated within the version control system - for example, if I add a column to a table I don't want to have to make sure that the change is in both a create script and an alter script The system needs to support multiple clients who are at various versions for the application (trying to get them all up to within 1 or 2 releases, but not there yet) Some organizations keep incremental change scripts in their version control and to get from version N to N + 3 you would have to run scripts for N-N+1 then N+1-N+2 then N+2-N+3. Some of these scripts can be repetitive (for example, a column is added but then later it is altered to change the data type). We're trying to avoid that repetitiveness since some of the client DBs can be very large, so these changes might take longer than necessary. Some organizations will simply keep a full database build script at each version level then use a tool like SQL Compare to bring a database up to one of those versions. The problem here is that intermixing DML scripts can be a problem. Imagine a scenario where I add a column, use a DML script to fill said column, then in a later version that column name is changed. Perhaps there is some hybrid solution? Maybe I'm just asking for too much? Any ideas or suggestions would be greatly appreciated though. If the moderators think that this would be more appropriate as a community wiki, please let me know. Thanks!

• asp.net mvc - limit access to web pages

  - by niao

  Greetings, in my asp.net mvc application what i would like to do is to enable access to some pages only after user was successfully authorized. I have already created custom membership provider and that works fine. How can I, in web config create such rule - for instance for all pages in ~Admin/ folder? I don't want to create on every controller's action the validation code. For now i have in my web.config the following statement: <location path="~/Admin"> <system.web> <authorization> <deny users="?"/> </authorization> </system.web> but it doesn't work.

• crosshair tool, is there one? Visual studio 2008

  - by flavour404

  Hi, I am doing some image sampling. What my question is, is there a 'crosshair' tool in visual studio? I want to have several instances on a single form, be able to move them around and then sample those points, obviously returning the color of the pixel at the center of the crosshair, is there already a tool that will do this, before I go and write one? Thanks, R.

• Trying to understand Java RSA key size

• Sending E-Mail in C#

  - by pm_2

  I’m using .NET 3.5, and I want to automatically send a mail. I’m currently using the following: Microsoft.Office.Interop.Outlook.MailItem mailMsg = (Microsoft.Office.Interop.Outlook.MailItem)outlookApplication.CreateItem( Microsoft.Office.Interop.Outlook.OlItemType.olMailItem); mailMsg.To = recipient; mailMsg.Subject = subject; mailMsg.Body = body; mailMsg.Send(); However, I’ve found several articles that seem to imply I should be using the following method: System.Net.Mail.MailMessage mailMsg = new System.Net.Mail.MailMessage(); mailmsg.To = recipient; mailmsg.Subject = subject; mailmsg.Body = body; Can anyone tell me what the difference between the two namespaces if, and why you might want to use one over the other?

• [java] How to get ALL the information from a socket

  - by raven

  Hello, I'll begin this question with the claim that I have read the java networking guide before asking you. I do not understand how to READ the socket and get all the info summed up into a string. the socket might contains more than 1 line [trying to make a chat]. Please do no refer me to any other site unless it clearly states "this exact line does this.." because I failed to understand what this code part does BufferedReader stdIn = new BufferedReader( new InputStreamReader(System.in)); String userInput; while ((userInput = stdIn.readLine()) != null) { out.println(userInput); System.out.println("echo: " + in.readLine()); } Please, I just want to make a loop that will receive information from a socket, get all the content together into one string [I also want it to know where to add another line]. Thanks allot for anyone who helps, I have been trying to get an answer from tuts for hours and just failed to understand!

• Type casting problem with java for-each loop

  - by pharma_joe

  Hi, I have traced an issue with an application I am developing, it is giving me a type cast exception. Funny thing is it is saying it cannot cast "entities.Movie cannot be cast to entities.Movie"?! movies is an ArrayList. try { movies = getMovies(); } catch (Exception e) { e.printStackTrace(System.out); } finally { try { for (Movie movie : movies) { output.append(" <tr>\n"); output.append(" <td>" + movie.getId() + "</td>"); output.append(" </tr>\n"); } } catch (Exception e) { e.printStackTrace(System.out); } }

  - by John

  Hi.... This is a exremely stupid question but i need help with this.... I'm trying to make a small program that i made robust and needed some help with tht.... int num1; int num2 = 0; System.out.print("Enter number 1: "); num1 = kb.nextInt(); while(num2<num1) { System.out.print("Enter number 2: "); num2 = kb.nextInt(); } Number 2 has to be greater than number 1 Also i want the program to automatically check and ignore if the user enters a char instead of an int... Cause right now when a user enters lets say "r" instead of a number the program just exists....

• Java generic function for performing calculations on integer, on double?

  - by Daniel

  Is this possible? Surely if you passed in a double, any sort of function implementation code which casts an object to an Integer would not be able to work unless the cast 'Integer' was specifically used? I have a function like: public static void increment(Object o){ Integer one = (Integer)o; system.out.println(one++); } I cant see how this could be made generic for a double? I tried public static <E> void increment(E obj){ E one = (E)o; system.out.println(one++); } but it didn't like it?

• inputMismatchException Java reading doubles from plain text file

  - by user939287

  Using double variable = inputFile.nextDouble(); Gives the mismatch error and I can't figure out why... Anyone know what's up? The input file is just a bunch of doubles like 5.0... Okay here is the code snippet String fileName; Scanner scanner = new Scanner(System.in); System.out.println("\nEnter file name that contains the matrix and vector: "); fileName = scanner.nextLine(); Scanner inputFile = new Scanner(fileName); double a1 = inputFile.nextDouble(); the input file is a plain text document .txt in this format 5.0 4.0 -3.0 4.0 2.0 5.0 6.0 5.0 -2.0 -13.0 4.0 12.0 I don't understand why it wouldn't take those as doubles... As far as what its expecting the format of the file to be... I suppose binary? isn't that the default? I didn't specify in the code...

• Help identify the layout used here?

  - by Matt Huggins

  I'm working on a layout that comprises some of the same features seen in the screenshot below, but I'm running into a bit of confusion. Can someone help me understand a few points for the screenshot below? What is the root layout used here? How do I get the button bar to remain at the bottom, while the center section scrolls when it is long enough? Similar to the Ok/Cancel buttons seen here, how do I make them each 50% width (minus some margin and padding)?

• Why do I have to give an identifier?

  - by Knowing me knowing you

  In code: try { System.out.print(fromClient.readLine()); } catch(IOException )//LINE 1 { System.err.println("Error while trying to read from Client"); } In code line marked as LINE 1 compiler forces me to give an identifier even though I'm not using it. Why this unnatural constrain? And then if I type an identifier I'm getting warning that identifier isn't used. It just doesn't make sense to me, forcing a programmer to do something unnecesarry and surplus. And after me someone will revise this code and will be wondering if I didn't use this variable on purpouse or I just forgot. So in order to avoid that I have to write additional comment explaining why I do not use variable which is unnecessary in my code. Thanks

• What is the worst source control you have used? [closed]

  - by David Liddle

  There are many discussions about what people's favourite source control is (subversion, mercurial ...). But what source control systems have you used that you certainly wouldn't recommend? And more beneficial, how would you go about promoting change in the business to a new source control system? A few years ago I developed using a source control system called Synergy. There were two Synergy experts in the company that constantly had to help the developers do check-ins/outs and merges were especially difficult. What would be your steps of migrating to a better source control. Would you host everything internally or pay for services such as github?

• No class def find error

  - by John Smith

  I have the following piece of code which helps me to read the paths of all the files in a directory and its subdirectories : File dir = new File("directory path"); try { System.out.println("Getting all files in " + dir.getCanonicalPath() + " including those in subdirectories"); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } List<File> files = (List<File>) FileUtils.listFiles(dir, TrueFileFilter.INSTANCE, TrueFileFilter.INSTANCE); for (File file : files) { try { System.out.println("file: " + file.getCanonicalPath()); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } } The problem is that I get a java.lang.NoClassDefFoundError: org/apache/commons/io/filefilter/TrueFileFilter error. I've imported the necessary libraries. I mention that I work on a plugin project. This code runs in a class with main function. I don't understand why it gave me this error. Thank you !

• "Passing Go" in a (python) date range

  - by anonymous coward

  The Rules: An employee accrues 8 hours of Paid Time Off on the day after each quarter. Quarters, specifically being: Jan 1 - Mar 31 Apr 1 - Jun 30 Jul 1 - Sep 30 Oct 1 - Dec 31 The Problem Employees will use an automated system to request paid time off, possibly occurring in the past, as well as the future. Requests should only be accepted if the employee has (or will have) that time available. For instance, if an employee only has 1 Day of Paid Time Off currently available (currently being January 20th), but is requesting 2 Days of Paid Time Off, beginning September 20th, the system should take into account that the employee would have accrued enough time off by then and allow the request. (Obviously ignoring that the employee may use up existing time before that date). I'm currently using Python, and wondering what the correct approach to something like this would be. I'm assuming that using DateTime objects, and possibly the dateutil module, would help here, but my brain isn't wrapping around this problem for some reason.

• CSS Not Centering Container

  I have a container div. Width: 80%, margin-left: 10% and margin-right 10%. The problem is, the container is displaying to the left in all the browsers I check. If I change the value of margin-left to 20%, it looks ok. I will supply code if necessary but is there anything obviously wrong here? Isn't 80 with a margin of 10 on each side correct to center a div? GF

• C# Launcher program(ConsoleApp) that launches other executables

  - by Agile Noob

  I've written a launcher program that fires off a given number of executables, with the following code: Process.Start(strPath2EXE); The problem I'm running into is it seems I'm being limited to launching only about four copies of the executable. Is there a different way I can launch the executables without this limit? I'm hoping to run 10+ concurrently. Here is the error from the event log: EventType clr20r3, P1 launcher.exe, P2 1.0.0.0, P3 4bec3901, P4 system, P5 2.0.0.0, P6 4889de7a, P7 39f5, P8 288, P9 system.componentmodel.win32, P10 NIL.
