• Which is a good opensource user management system?

  - by Lost_in_code

  I'm new to php/mySQL and am trying to create a website which will allow users to register. In future, there will be a paid content area where content will be shown based on the payment status. Is there a good opensource lightweight framework which takes care of the user management part? (Register, edit user info, retrieve lost password etc). I'm a flash platform developer and not aware of how to take care of stuff like session hijacking, XSS etc. Should I go ahead and learn to do all this on my own, without using any framework? I thought of using Wordpress' user management system, but not sure how easy that would be. Any suggestion would be great.

• Convert Microsoft Visio Drawing (vsd) to PDF automatically

  - by nhinkle

  An open-source project I am working on uses Visio drawings for documentation, which are checked into source control. For those working on the project who don't own Visio, we have been converting the vsd files to PDFs so that they can still view them. It's not too difficult to save a copy as a PDF when making changes to the documentation, but we would like an automated way to do this conversion, so that we can set it up as a pre-checkin script in the SVN client. If anybody knows of a way to do this, either using something built-in to Visio, or with an outside script or command line tool, we would appreciate it. Edit: Thanks to the suggestion below, I have found the Visio Viewer 2010. This will be helpful for our contributors using Windows. We would still like to have the ability to create PDFs though, as there are readers available on every major operating system, and our contributors will not be using only Windows.

• UITextView text disappear

  - by user153412

  Hi, i create an uitextview dynamically then i write my text into it. Sometime, when i create the uitextview, the cursor disappear and i see no text in it. If i run the application again, i can see the text inside the textview that i've created before. I've tried to set the cursor position to zero or scroll the text to the top but it doesn't work... Any suggestion? Here is a screen capture. You can see the gray uitextview, the keyboard (the textview is the firstresponder) but no cursor or text. http://yfrog.com/hqschermata20100325a11213p PS: i'm sorry for my bad english.

• Configure Tomcat to send web pages compatible to IE 7 or 6

  - by Spiderman

  I have got an application that is not compatible to work using IE8 browser. I am looking for a way to to configure Tomcat on which this application run, so the pages could be read by IE8 and treated as if they are IE7 or IE6 By googling so far I found a possible suggestion which say to add to the http response the header: X-UA-Compatible: IE=EmulateIE7 here that tell IE8 to be like IE7. The problem is that this way requires adding a filter that should be added on application level. I'd like to know if any of you is familiar with a more generic way that Tomcat enables to send its http content to be IE7 (or IE6) compatible ?

• FBConnect for iPhone: sessionDidNotLogin, sessionDidLogout, session didLogin not called the second t

  - by Irene

  My problem is very similar to this question, however I am posting a new one, as the answer to the aforementioned does not seem to solve my problem. I have a multiview application - the first view is where the user logs in to Facebook, and the second where he picks an image and uploads it there. The first time the app runs, everything works fine, however if I return to the login view and press logout, then any calls to sessionDidNotLogin, sessionDidLogout or session didLogin don't seem to work. I found out that the first time, if I NSLog(@"%@",session.delegates); I have 2; my LoginViewController and the FBLoginButton. However, apart from that first time, the same log prints only the LoginViewController and not the FBLoginButton. I guess this is connected somehow, but I don't know how to solve it. Do I have to manually add the FBLoginButton to the session delegates, or I'm doing something else wrong here? Thank you for any help/suggestion.

• JNA-Mapping Delphi Function

  - by Florian

  Hi! How do i map this function with JNA: Delphi code: function getData(InData1: PChar; InData2: PChar; Data: TArray16; var OutData1: PChar; var OutData2: PChar): integer; stdcall; with: TArray16 = array[0..15] of char; The int value that is returned can be 0 for Error or 1 for right execution; My suggestion is: Java code: int getData(String inData1, String inData2, byte[] data, byte[] outData1 byte[] outData2); The problem is that the function of the dll returns 0. I also tried other Datatypes, but it hasn't worked jet. I think the problem is that the dll function can't write to the parameters outData1 and outData2. Who can help me?....Thanks!!

• Change present working directory of a calling shell from a ruby script

  - by Erik Kastman

  I'm writing a simple ruby sandbox command-line utility to copy and unzip directories from a remote filesystem to a local scratch directory in order to unzip them and let users edit the files. I'm using Dir.mktmpdir as the default scratch directory, which gives a really ugly path (for example: /var/folders/zz/zzzivhrRnAmviuee+++1vE+++yo/-Tmp-/d20100311-70034-abz5zj) I'd like the last action of the copy-and-unzip script to cd the calling shell into the new scratch directory so people can access it easily, but I can't figure out how to change the PWD of the calling shell. One possibility is to have the utility print out the new path to stdout and then run the script as part of a subshell (i.e. cd $(sandbox my_dir) ), but I want to print out progress on the copy-and-unzipping since it can take up to 10 minutes, so this won't work. Should I just have it go to a pre-determined, easy-to-find scratch directory? Does anyone have a better suggestion? Thanks in advance for your help. -Erik

• Can I use swank-clojure with the clojure 1.2 master branch?

  - by Rob

  I'm happily using swank-clojure, installed via elpa. But I'd like to do some work with deftype, defprotocol, etc., which aren't aren't available in clojure 1.1. To use my own class paths, I'm using the excellent suggestion by Rick Moynihan in the stackoverflow question about setting custom classpaths, which was to set up a script like: #!/bin/bash java -server -cp "./lib/*":./src clojure.main -e "(do (require 'swank.swank) (swank.swank/start-repl))" And that works swimmingly if the clojure jar file in lib is 1.1, but with 1.2, it blows up: Exception in thread "main" java.lang.NoSuchMethodError: clojure.lang.RestFn.<init>(I)V (macroexpand.clj:1) at clojure.lang.Compiler.eval(Compiler.java:5274) at clojure.lang.Compiler.load(Compiler.java:5663) at clojure.lang.RT.loadResourceScript(RT.java:330) at clojure.lang.RT.loadResourceScript(RT.java:321) at clojure.lang.RT.load(RT.java:399) at clojure.lang.RT.load(RT.java:371) at clojure.core$load__5663$fn__5671.invoke(core.clj:4255) at clojure.core$load__5663.doInvoke(core.clj:4254) at clojure.lang.RestFn.invoke(RestFn.java:409) ...and many, many more So is there some magical incantation to make this work, or is clojure 1.2 compatibility not there yet?

• retrieve cobol s9(2) COMP onto C variable

  - by Pablo Cazallas

  Hi, I need to retrieve data from a COBOL variable of the type: "PIC S9(2) COMP" onto a C variable of the type "int". It's stored using two bytes of a string, so I receive it as a couple of chars. I know COBOL stores decimal data onto a "S9(2) COMP" in binary format, so It would be a great help letting me know any algorithm or way to convert it safely. Any kind of help & suggestion will be welcome. Thanks in advance and regards, Pablo.

• Can NotifyIcon.ShowBalloonTip in C# be customized?

  - by badpanda

  Purely out of GUI vanity, I would like to make my task bar tool tip less...well, less "I wear a suit and work at Microsoft"-y. I can't seem to find a setting to do this, but I know that this particular function is relatively new so if anyone knows of a way to change the balloon look and feel I would very much appreciate a link or suggestion! Below is my code: public static void shutdownWarning() { ToolTipIcon tipIcon = new ToolTipIcon(); tipIcon = ToolTipIcon.None; TaskBarIcon.getInstance().mNotifyIcon.ShowBalloonTip(100, "", "Sending. Please do not shut down.", tipIcon); } Cheers!! badPanda

• How can I prevent tab characters etc. from being pasted into an asp.net textbox?

  - by Neal

  Hello, I'd like to have an asp.net textbox that people can paste content into and it works like notepad, i.e. no formatting or special characters will get entered. I take text and pass it to a web service which manipulates it and converts it into a tab delimited file. The problem I've experienced is sometimes people copy from MS Word and paste that content in and somehow even the tab characters etc. get passed to the web service. I run routines now to strip that information out but it would be so much easier if the textbox on the web page didn't capture anything but the text itself, i.e. visible characters (numbers, letters, punctuation). Anyone have a suggestion to have a textbox that doesn't capture formatting and non-visual characters? Thank you.

• Visual Studio DTE2: how to get text content of the current document

  - by Sylvain

  I developped a package to extend Visual Studio. As part of it, I have a context menu that must process the whole text content of the active document (HTML editor). I understand how to get the current selection : TextSelection txtSelection = (TextSelection)_bllManager.CurrentDocument.Selection; But I dont't understand how to get the whole content of the code window in case nothing is selected. Currently I use a work-around doing txtSelection.SelectAll() but it moves the cursor and I don't want that. Any suggestion ? Thanks.

• WPF Validation with ContentPresenter

  - by Chris

  Hi, I have a WPF user control which needs to validate some fields. It is bound to a class implementing IDataErrorInfo. When I set the user control as the content of my ContentPresenter in another, already open, window, I can see validation occurring, and error messages being returned, however, I don't get any validation adorner - e.g. the default red outline. If I enter the field and leave it (triggering re-validation) the validation adorner appears. Also, if I show the user control in it's own window it shows the validation adorner immediately. (I'm using Caliburn IResults to do this underneath, e.g. Show.Dialog<VM>(); but I suspect this isn't related) Can anyone offer any suggestion why the validation adorners aren't appearing immediately. (I had guessed animation on my ContentPresenter ContentChanged, however, I have removed this and still experience the problem. thanks, Chris
