  • PHP: Is mysql_real_escape_string sufficient for cleaning user input?

    - by Thomas
    Is mysql_real_escape_string sufficient for cleaning user input in most situations? ::EDIT:: I'm thinking mostly in terms of preventing SQL injection but I ultimately want to know if I can trust user data after I apply mysql_real_escape_string or if I should take extra measures to clean the data before I pass it around the application and databases. I see where cleaning for HTML chars is important but I wouldn't consider it necessary for trusting user input. T

    - by Thomas
    Hi, I'm changing the form action with: window.onload = function() { document.getElementById('pdf').onclick = addExportEvent; document.getElementById('xls').onclick = addExportEvent; document.getElementById('xml').onclick = addExportEvent; document.getElementById('csv').onclick = addExportEvent; } function addExportEvent() { data = grid.getAllGridData(); document.getElementById('dados').setAttribute('value', encodeURIComponent(JSON.stringify(data))); formulario = document.getElementById('formulario'); // Line 55! formulario.action = 'php/' + this.id + '.php'; formulario.submit(); return false; } But it doesn't work with Internet Explorer.

  • How can my WiX uninstall restore a registry value change?

    - by Thomas
    The installer I'm writing using WiX 3.0 uses a RegistryValue element to modify an existing registry value (originally written by our main product). I'm trying to figure out a way to restore the registry value when the user uninstalls my utility. I'd like to avoid using a custom action, but that might be the only recourse? TIA.

  • Docking *inside* an editor

    - by Andy Thomas-Cramer
    I have a document type which has multiple presentations. Say I want to display the document in an RCP editor with a customizable subset of those presentations, in a layout chosen by the user. One option that has come up is docking-like behavior for the panels inside an individual editor, with drag-and-drop, resizing, closing, maybe rollover and floating. Clearly this would need usability testing, but my question here is of feasibility. Are there any existing libraries or e4 plans to support behavior like this?

  • Position a UIView at the middle of a UITableView with CGRectZero frame

    - by Thomas Joulin
    Hi, I have a UITableViewController view a UITableView that I alloc/init with a frame of CGRectZero : self.tableView = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStyleGrouped]; I want to add a view at the middle of the tableView (a loading view with a UIActivityIndicatorView and a UILabel), but I don't know how to position it, since I don't know the tableView frame. x = (self.tableview.frame.size.width - loadingView.frame.size.width) / 2.0; y = (self.tableview.frame.size.height - loadingView.frame.size.height) / 2.0; [loadingView setCenter:CGPointMake(x, y)]; I did init my tableView with CGRectZero frame so it can take the whole place available on screen (which it did), but I thought its frame would update or something. Any ideas ? Thanks !

  • Twitter s'éloigne de plus en plus de ses développeurs externes, quel avenir pour leurs applications

    Mise à jour du 14.04.2010 par Katleen Twitter s'éloigne de plus en plus de ses développeurs externes, quel avenir pour leurs applications face aux outils officiels ? A ses débuts, le site de micro-blogging Twitter n'avait pas les moyens financiers de ses ambitions. Aussi s'est-il appuyé sur l'aide de développeurs externes qui lui ont crée gratuitement des services et des outils, en échange de revenus publicitaires. C'est grâce à ces programmeurs que les utilisateurs du réseau communautaire peuvent aujourd'hui raccourcir leurs URLs, poster des twitpics, gèrer plusieurs comptes en même temps, etc. Le travail des développeurs extérieurs a donc largement contribué à l'ascension vertigineuse du sit...

  • Authenticating GTK app to run with root permissions

    - by Thomas Tempelmann
    I have a UI app (uses GTK) for Linux that requires to be run as root (it reads and writes /dev/disk*). Instead of requiring the user to open a root shell or use "sudo" manually every time when he launches my app, I wonder if the app can use some OS-provided API to ask the user to relaunch the app with root permissions. (Note: gtk app's can't use "setuid" mode, so that's not an option here.) The advantage here would be an easier workflow: The user could, from his default user account, double click my app from the desktop, and the app then would relaunch itself with root permission after been authenticated by the API/OS. I ask this because OS X offers exactly this: An app can ask the OS to launch an executable with root permissions - the OS (and not the app) then asks the user to input his credentials, verifies them and then launches the target as desired. I wonder if there's something similar for Linux (Ubuntu, e.g.) Update: The app is a remote operated disk repair tool for the unsavvy Linux user, and those Linux noobs won't have much understanding of using sudo or even changing their user's group memberships, especially if their disk just started acting up and they're freaking out. That's why I seek a solution that avoids technicalities like this.

  • How is ImmutableObjectAttribute used?

    - by Thomas Levesque
    I was looking for a built-in attribute to specify that a type is immutable, and I found only System.ComponentModel.ImmutableObjectAttribute. Using Reflector, I checked where it was used, and it seems that the only public class that uses it is System.Drawing.Image... WTF? It could have been used on string, int or any of the primitive types, but Image is definitely not immutable, there are plenty of ways to alter its internal state (using a Graphics or the Bitmap.SetPixel method for instance). So the only class in the BCL that is explicitly declared as immutable, is mutable! Or am I missing something?

  • Saving data so it can be loaded locally

    - by Thomas Joos
    hi guys, i'm working on iphone application which needs to run offline at an exhibition. It should present data, stored local because there is no internet at the booth. Still, to easily have content updates it should be able to update it's content once connected to internet. It's quite some data ( around 300 full lines of text ) and I want it to be loaded, stored and visualized as optimized as possible. What's the best way to load in content once connected and how should I store it on the device?

  • hibernate sybase db power function

    - by Vipin Thomas
    We are trying to use sybase function power to do mathematical calculation for one of the DB columns. The hibernate is generating power function as pow(?, xyzo0_.AmtScale) whereas sybase supports power function as Syntax POWER( numeric-expression-1, numeric-expression-2 ) We have tried modifying the hibernate.dialect. Have tried org.hibernate.dialect.SybaseASE15Dialect org.hibernate.dialect.Sybase11Dialect org.hibernate.dialect.SybaseAnywhereDialect but all dialects generate the power function as pow(?, xyzo0_.AmtScale). Is this hibernate issue or are we missing something?

  • Maven copy project output into other project resources

    - by Thomas
    There are two projects: 1) applet project that outputs jar file 2) web app project that should host the jar file. After (1) finished building, the applet jar file should be copied into the webapp folder of (2). The purpose is that (2) will host the applet (1) on the Internet. A lot of examples explain how to use another project as a library dependency. Other examples, show how to use ant plugin to copy files. I am unsure on how to properly set this up, so that 'mvn install' on the parent project will do the copying at the right time.

  • What is the header of an array in .NET

    Hi all, I have a little bit seen the representation of an array in memory with Windbg and SOS plugin.

  • Is there a way to disable calls to Runtime.checkRestricted on the GAE Java development server under Eclipse?

    - by Thomas Becker
    I'm one of those guys who step through their code a lot during development. Beginning with version 1.6.4 of the GAE Java development server, the server has been instrumented with calls to a function named Runtime.checkRestricted. This causes two inconveniences when I step through my code: 1) Whenever I step into a function, the debugger goes into the function Runtime.checkRestricted (for which there is no source code) at least once, often multiple times. 2) Whenever I step over a function call which has a large call tree underneath it, then it takes a very long time for the debugger to come back. (That's always a problem in the Eclipse Java debugger, but now it's really bad.) For me, all this causes a serious drain on productivity. Is there any way to disable this instrumentation, or to prevent the debugger from stepping into it? I am using Eclipse with the GAE plugin.

  • Initialization of std::vector<unsigned int> with a list of consecutive unsigned integers

    - by Thomas
    I want to use a special method to initialize a std::vector<unsigned int> which is described in a C++ book I use as a reference (the German book 'Der C++ Programmer' by Ulrich Breymann, in case that matters). In that book is a section on sequence types of the STL, referring in particular to list, vector and deque. In this section he writes that there are two special constructors of such sequence types, namely, if Xrefers to such a type, X(n, t) // creates a sequence with n copies of t X(i, j) // creates a sequence from the elements of the interval [i, j) I want to use the second one for an interval of unsigned int, that is std::vector<unsigned int> l(1U, 10U); to get a list initialized with {1,2,...,9}. What I get, however, is a vector with one unsigned int with value 10 :-| Does the second variant exist, and if yes, how do I force that it is called?

  • Python nested function scopes

    - by Thomas O
    I have code like this: def write_postcodes(self): """Write postcodes database. Write data to file pointer. Data is ordered. Initially index pages are written, grouping postcodes by the first three characters, allowing for faster searching.""" status("POSTCODE", "Preparing to sort...", 0, 1) # This function returns the key of x whilst updating the displayed # status of the sort. ctr = 0 def keyfunc(x): ctr += 1 status("POSTCODE", "Sorting postcodes", ctr, len(self.postcodes)) return x sort_res = self.postcodes[:] sort_res.sort(key=keyfunc) But ctr responds with a NameError: Traceback (most recent call last): File "PostcodeWriter.py", line 53, in <module> w.write_postcodes() File "PostcodeWriter.py", line 47, in write_postcodes sort_res.sort(key=keyfunc) File "PostcodeWriter.py", line 43, in keyfunc ctr += 1 UnboundLocalError: local variable 'ctr' referenced before assignment How can I fix this? I thought nester scopes would have allowed me to do this. I've tried with 'global', but it still doesn't work.

  • How to find the mime type of a file in python?

    - by Daren Thomas
    Let's say you want to save a bunch of files somewhere, for instance in BLOBs. Let's say you want to dish these files out via a web page and have the client automatically open the correct application/viewer. Assumption: The browser figures out which application/viewer to use by the mime-type (content-type?) header in the HTTP response. Based on that assumption, in addition to the bytes of the file, you also want to save the MIME type. How would you find the MIME type of a file? I'm currently on a Mac, but this should also work on Windows. Does the browser add this information when posting the file to the web page? Is there a neat python library for finding this information? A WebService or (even better) a downloadable database? Edit: Thank you, Dave Webb.
