• Restrict file access from PHP -> Java Applet

  - by aliuy

  I'm writing a portal in PHP that allows users to upload DICOM images, and allow users of the same group to view those DICOM images through a Java Applet. The html code to display images through the viewer looks like this: <APPLET archive=radscaper.jar codebase=./ code=com.divinev.radscaper.Main.class width=100% height=100%> <PARAM NAME=Config VALUE=config.xml> <PARAM NAME=DicomImg1 VALUE="relative_path1/image1.dcm"> </APPLET> So the generated html passes in a file url to the java applet. The problem I'm facing is - files would be stored in a public directory and easily accessed by anyone knowing the file url. Is there a way I can restrict file access to a certain user group?

• EXC_BAD_ACCESS when not using self.

  - by chris

  I got nabbed by the following bug again and would like some clarification to exactly why it is a bug. I have a simple UITableView that loads some data: // myclass.h @property (nonatomic, retain) NSArray *myData // myclass.m @synthesize myData; - (void) viewDidLoad { ... myData = someDataSource // note the lack of self } - (UITableViewCell *) cellForRowAtIndexPath ... { ... cell.textLabel.text = [self.myData objectAtIndex:indexPath.row]; // EXC_BAD_ACCESS } The table first loads fine, but when scrolling up enough that one of the cells is totally out of the view I then get the EXC_BAD_ACCESS error. Am I missing something in regards to @property retain. My understanding is that it releases anything that the pointer was previously pointing to before the reassignment. If I am correct then why would not using self. cause any problems? Thanks for the help.

• Is there an easy way to make `boost::ptr_vector` more debugger friendly in Visual Studio?

  - by Billy ONeal

  I'm considering using boost::ptr_container as a result of the responses from this question. My biggest problem with the library is that I cannot view the contents of the collection in the debugger, because the MSVC debugger doesn't recognize it, and therefore I cannot see the contents of the containers. (All the data gets stored as void * internally) I've heard MSVC has a feature called "debugger visualizers" which would allow the user to make the debugger smarter about these kinds of things, but I've never written anything like this, and I'm not hugely firmiliar with such things. For example, compare the behavior of boost::shared_ptr with MSVC's own std::tr1::shared_ptr. In the debugger (i.e. in the Watch window), the boost version shows up as a big mess of internal variables used for implementing the shared pointer, but the MSVC version shows up as a plain pointer to the object (and the shared_ptr's innards are hidden). How can I get started either using or implementing such a thing?

• C# Xamarin.IOS / MonoTouch - Toolbar Disappears

  - by Goober

  I have a Xamarin.IOS/Monotouch project with 2 views - MainView and View2. My MainView window has a navigationController at the top, and a toolbar at the bottom. When I call PushViewController(View2,true); - I get pushed from MainView to my second view (View2). View2 also has a navigationController at the top, but it DOES NOT have a toolbar at the bottom - intentionally. When I click the "Back" button on View2 to push back to my MainView, the toolbar at the bottom of MainView has disappeared. Any ideas on how to get around this? Much appreciated.

• fixed vertical positioning of css within an iframe

  - by Jake Rider

  I am trying to get my bottom header to stick to the bottom of the screen inside of my iframe application and have it always appear in view for the user even when the page is scrolling. I have no control over the outer iframe as it is on a different domain. The header itself must be inside of the iframe as I have no control outside the iframe. The iframe always expands to the height of its contents so that it has no scrollbars, but the bar still has to be visible in the viewport at all times.

• CF - Mobile Managed Gestures

  - by no9

  Im looking for a nice demo/sample using Windows Mobile Managed Gestures. I have a main view that contains a single panel. Every item in the panel is another panel containing pictureBox and a label. I would like to implement scrooling (finger flicking) to avoid using thin scroolers. Are the Windows Mobile Managed Gestures the right solution to get this working, if so can some one provide me with a begginers demo? I downloaded the source code from http://code.msdn.microsoft.com/gestureswm/Release/ProjectReleases.aspx?ReleaseId=3438 but i would need a simple example using this source. Also a question ... does this work only on 6.5? Even if i got this working is there a way to support this in 6.0 ? thanx!

• Updating Android Home Screen TextView

  - by jmontex2

  Hi, How can we update the View of a Home Screen Widget on the onReceive method of AppWidgetProvider?. I am trying to update the TextView of my Home screen widget but it seems that I cant access the TextView of my AppWidgetProvider on onReceive method. Here is a sample code of my onReceive public void onReceive(Context context,Intent intent) { final String action = intent.getAction(); if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) { final int appWidgetId = intent.getExtras().getInt( AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID); if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) { this.onDeleted(context, new int[] { appWidgetId }); } } else { if (intent.getAction().equals(ACTION_WIDGET_RECEIVER)) { String msg = "null"; try { msg = intent.getStringExtra("msg"); } catch (NullPointerException e) { } Toast.makeText(context, msg, Toast.LENGTH_SHORT).show(); // code for gathering the text to update the TextView } } super.onReceive(context, intent); }

• Will news ticker using overflow:hidden cause Google to see site as spam?

  - by molipix

  In the hope of tempting Googlebot with fresh content, I've implemented a homepage news ticker which displays the 20 most recent headlines on our site. The implementation I have chosen is a <ul> with each headline being a <li> Initially all the <li> elements have no style but Javascript kicks in on page load and gives all but one of them a display="style:none" attribute. Javascript then displays each of the other 19 headlines in a loop. So far so good. However, in order to prevent a visually unplesant page load where the 20 items display and then immediately collapse, I am using overflow:hidden on the <ul> element. Anyone got a view on what Googlebot is likely to make of this? Does the fact that I'm using overflow:hidden make the content look like spam?

• WiX: Extracting Binary-string in Custom Action yields string like "???good data"

  - by leiflundgren

  I just found a weird behaviour when attempting to extract a string from the Binary-table in the MSI. I have a file containing "Hello world", the data I get is "???Hello world". (Literary question mark.) Is this as intended? Will it always be exactly 3 characters in the beginning? Regards Leif Sample code: [CustomAction] public static ActionResult CustomAction2(Session session) { View v = session.Database.OpenView("SELECT `Name`,`Data` FROM `Binary`"); v.Execute(); Record r = v.Fetch(); int datalen = r.GetDataSize("Data"); System.IO.Stream strm = r.GetStream("Data"); byte[] rawData = new byte[datalen]; int res = strm.Read(rawData, 0, datalen); strm.Close(); String s = System.Text.Encoding.ASCII.GetString(rawData); // s == "???Hello World" return ActionResult.Success; }

• ZendFramework integration with other frameworks

  - by St.Woland

  I want to make this question a guide for those interested in ZendFramework integration with other libraries/frameworks. Searching over StackOverflow doesn't give a broad view on the subject. The question is: which libraries/frameworks do you use in your current ZF-based project? what are the best practices for ZF-based project architecture? I don't mean any components that are already a part of ZF. Please give a description of aditional frameworks you have integrated (like RuckUsing, Smarty, or Doctrine). It also applies to any GUI frameworks (perhaps you use a CSS framework), as well as JS frameworks (not just jQuery or prototype, but rather some advanced structures). The main requirement: it has to be a ZendFramework project. Additional bonus will be given to answers that describe performance optimization.

• show definition (browse) in *.pdb of *.dll file

  - by ala

  I have built a Library project (DLL) in .NET. And sometimes I use the DLL along with its PDB file as a reference in some other projects. Now in the new project, I cant browse through the code of the DLL to debug. I can only see the definitions of class/methods/variables. That's by using "show definition" by browsing through the "class view" However, only in case of an exception I the contents of the DLL opens and I could see the entire code of the DLL from the new project. How could I see the contents (code) of the DLL before an exception occur?

• iphone Memory gets freed in debug mode but not in release mode

  - by gdr

  I have been testing my iPhone debug build on both my device and simulator with activity monitor, leaks, and object allocations. The code is pretty well optimized so I have decided to test the release build. I went into the project Menu and set the target build to be release, I then added the necessary header paths that my app is using to the headers search paths and ran the release build on the device with the above mentioned instruments. What I have noticed now is that memory that was freed when I used the debug build does not get freed when using release version. There is one place in my App that I remove a scroll view with some images which frees up a significant amount of memory when I use the debug build, but no memory is freed up in that place when I use the release version. Does someone have any ideas where I need to start looking at? did I setup my release build wrong?

• Using TTSearchBar with TTThumbsViewController

  - by scompt.com

  I would like to layout a TTSearchBar above above a TTThumbsViewController. My current (failing) attempt involves my own SearchViewController that inherits from TTViewController and contains a reference to a TTThumbsViewController and TTSearchBar. In the loadView method, I instantiate both TTThumbsViewController and TTSearchBar and add them (actually, ..the view property of the TTTVC) as subviews. When the SearchViewController is pushed, neither the TTThumbsViewController nor the TTSearchBar are displayed. Am I going about this wrong? Is there a better way to add search to the TTThumbsViewController?

• Get data types from arbitrary sql statement in SQL Server 2008

  - by Christopherous 5000

  Given some arbitrary SQL I would like to get the data types of the returned columns. The statement might join many tables, views, TVFs, etc. I know I could create a view based on the query and get the datatypes from that, hoping there's a quicker way. Only think I've been able to think of is writing a .net utility to run the SQL and examine the results, wondering if there is a TSQL answer. i.e. Given (not real tables just an example) SELECT p.Name AS PersonName, p.Age, a.Account as AccountName FROM Person as p LEFT JOIN Account as a ON p.Id = a.OwnerId I would like to have something like PersonName: (nvarchar(255), not null) Age: (smallInt, not null) etc...

  I have common functionality that I need to access from all screens of my app: a right bar button item and associated action. So as not to repeat the code I would like to set this up in a custom UIViewController and have all my view controllers inherit from it. - (void)viewDidLoad { UIBarButtonItem *rightBarButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemPlay target:self action:@selector(lightsCamera)]; self.navigationItem.rightBarButtonItem = rightBarButton; } - (void)lightsCamera { … } However, I have a number of UITableViewControllers however and I would like to know if it is possible for them to inherit the functionality too?

• Get entire text of document as a string using javascript

I have been checking out javascript references and HTMLDocument etc. with no avail. Ideally I would be able to write to this buffer as well (seems possible i.e. document.writeLn()) I wish there was a document.read()? Am I just a js noob?
