• How can I programmatically unlock a Adobe DRM Epub?

  - by DEzra

  I am writing an ebook reader that supports the epub format (i have the parsing of open epub working), but I would like to support the reading of Adobe DRM locked epubs. I have read threw the adobe digital editions site (faq and support pages) and googled, but alas as yet I have not found any docs on the api to: authorise the pc using the users adobe id creds and decrypt the epub for parsing by my app. Does anyone have any pointers to docs or apis? I would prefer apis in Python, C++. But any api is better than nothing ;-) UPDATE1: i am writing my app on Desktops (linux, mac and windows)

• AutoMapper Mapping IEnumerable to DataReader Issue

  - by user74825

  I am using AutoMapper to datareader using code as discussed below http://elegantcode.com/2009/10/16/mapping-from-idatareaderidatarecord-with-automapper/ I see it being very flakky...and unpredictable. 1) Same code with same datareader at times brings value back to the dto result set and at times doesnot. 2) I have an ID value coming from database as 100, 200. When it maps to the DTO that is of type integer this 100 is changed to a large value (like 234343211). Any ideas on why am I seeing this inconsitency. Should I be using the standard while (reader.Read())? and stop using automapper?

• jerky animation using Core Animation

  - by Paul from Boston

  In my iPhone app, I am trying to get some red and white stripes that are scrolling across the screen to animate smoothly when the speed of the stripes gets high. In my app the user starts the animation and changes the scrolling speed by a finger swipe and changes the width of the stripes by a two finger pinch. Animation is stopped in response to a double tap. If the speed gets high or the stripes get narrow the animation is no longer smooth to the eye. The edges of the stripes seem to jump around. The animation is simple. I draw the stripes in a layer that's a bit larger than the screen. I then set up an animation that moves the layer position by exactly the distance from one red stripe to the next. The duration is set by the speed of the finger swipe and the repeat count is 1. When the animation stops the delegate checks a flag to see if the user wants to stop the scrolling. If not, the animation is restarted again for one cycle. Are there better ways of doing this so that the animation is smooth at high speeds or with narrow stripes? Thanks--

• Microsoft Expression Blend 3 - Show / Hide a popup

  - by imayam

  Hi, I'm using this for the very first time to do some quick prototyping (using sketchflow). I have a simple dialog window that I want to show when a button it pressed and then hide when a button (in the dialog, like an "OK" button) is pressed. If someone could just point me in the direction of a simple tutorial on how to do this I'd be happy, or even if you have a simple example you can post here that would be great (I've been trying to google this forever!). I can tell you what I have tried (although obviously it doesn't work) Created a user control, called it "MyDialog". That user control is a simple box which is the bit of gui I want to overlay when the user clicks a button. In that user control I gave it two states "Show" and "Hide". The "Hide" state has all visability to the elements in this user control set to none and "Show" shows everything Created a button in my main screen. That button I gave a it a behaviour "ActivateStateAction". In the properties of that behaviour I set the TargetScreen to be "MyDialog" and the TargetState to be "Show". (I also set the target screen to be MyprojectName.MyProjectNameScreens.MyDialog, that doesn't work either)

• Issue reading packets from a pcap file. dpkt

  - by Chris

  I am running the following test script to try to read packets from a sample .pcap file I have downloaded. 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?

• Reset scale/width/zoom of Safari on iPhone using JavaScript/onorientationchange

  - by dwarbi

  I am displaying different content depending on how the user is holding his/her phone using the onorientationchange call in the body tag. This works great - I hide one div while making the other visible. The div in portrait mode looks great on first load. I use this to get the right scale/zoom: <meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;" /> Even if the content in portrait mode run over, the width is correct and the user can scroll down. The display in landscape mode is perfect too. However, if content in landscape mode requires the user the scroll down, then when the user returns to portrait mode, the screen is "zoomed out" so to speak. This happens whether or not the user scrolled down while in landscape mode. I've tried many different things to try to get the scale/zoom/width of the screen right, but no luck. Is there any way to do this? Thanks in advance!

• Problem using FtpWebRequest to append to file on a mainframe

  - by MusiGenesis

  I am using FtpWebRequest to append data to a mainframe file. Each record appended is 50 characters long, and I am adding them one record at a time. In our development environment, we do not have a mainframe, so my code was written and tested FTPing to a Windows-based FTP site instead of a mainframe. Initially, I was writing each record using a StreamWriter (using the stream from the FtpWebRequest) and writing each record using WriteLine (which automatically adds a CR/LF to the end). When we ran this for the first time in the test environment (in which we're writing to an actual MVS mainframe), our mainframe contact said the CR/LFs were not able to be read by his program (a green-screen mainframe program of some sort - he's sent me screen captures, which is all I know of it). I changed our code to use Write instead of WriteLine, but now my code executes successfully (i.e no thrown exceptions) when writing multiple records, but no matter how many records we append, he is only able to "see" the first record - according to his mainframe program, there is only one 50-character record in the file. I'm guessing that to fix this, I need to write some other line-delimiting character into the end of the stream (instead of CR/LF) that the mainframe will recognize as a record delimiter. Anybody know what this is, or how else I can fix this problem?

• Changing the Android emulator locale automatically

  - by Christopher

  For automated testing (using Hudson) I have a script that generates a bunch of emulators for many combinations of Android OS version, screen resolution, screen density and language. This works fine, except for the language part. I need to find a way to change the Android system locale automatically. Here's some approaches I can think of, in order of preference: Extracting/editing/repacking a QEMU image directly before starting the emulator Running some sort of system-locale-changing APK on the emulator after startup Changing the locale settings on the emulator filesystem after startup Changing the locale settings in some SQLite DB on the emulator after startup Running a key sequence (via the emulator's telnet interface) that would open the settings app and change the locale Manually starting the emulator for each platform version, changing the locale by hand in the settings, saving it and archiving the images for later deployment Any ideas whether this can be done, either via the above methods or otherwise? Do you know where locale settings are persisted to/read from by the system? Solution: Thanks to dtmilano's info about the relevant properties, and some further investigation on my part, I came up with a solution even better and simpler simpler than all the ideas above! I have updated the answer below with the details.

• Interpolation and Morphing of an image in labview and/or openCV

  - by Marc

  I am working on an image manipulation problem. I have an overhead projector that projects onto a screen, and I have a camera that takes pictures of that. I can establish a 1:1 correspondence between a subset of projector coordinates and a subset of camera pixels by projecting dots on the screen and finding the centers of mass of the resulting regions on the camera. I thus have a map proj_x, proj_y <-- cam_x, cam_y for scattered point pairs My original plan was to regularize this map using the Mathscript function griddata. This would work fine in MATLAB, as follows [pgridx, pgridy] = meshgrid(allprojxpts, allprojypts) fitcx = griddata (proj_x, proj_y, cam_x, pgridx, pgridy); fitcy = griddata (proj_x, proj_y, cam_y, pgridx, pgridy); and the reverse for the camera to projector mapping Unfortunately, this code causes Labview to run out of memory on the meshgrid step (the camera is 5 megapixels, which apparently is too much for labview to handle) I then started looking through openCV, and found the cvRemap function. Unfortunately, this function takes as its starting point a regularized pixel-pixel map like the one I was trying to generate above. However, it made me hope that functions for creating such a map might be available in openCV. I couldn't find it in the openCV 1.0 API (I am stuck with 1.0 for legacy reasons), but I was hoping it's there or that someone has an easy trick. So my question is one of the following 1) How can I interpolate from scattered points to a grid in openCV; (i.e., given z = f(x,y) for scattered values of x and y, how to fill an image with f(im_x, im_y) ? 2) How can I perform an image transform that maps image 1 to image 2, given that I know a scattered mapping of points in coordinate system 1 to coordinate system 2. This could be implemented either in Labview or OpenCV. Note: I am tagging this post delaunay, because that's one method of doing a scattered interpolation, but the better tag would be "scattered interpolation"

• Just a general THANK YOU to EVERYONE. [closed]

  - by ajax81

  Hi All, I really just wanted to thank everybody that participates in the stackoverflow community. On more than one occasion, your minds have saved me from soul-eating project managers and career-ending deadlines. The commendable awareness exhibited by contributors that their answers are studied/used as learning material by millions of developers all over the world has created a regulated trust that seemingly keeps the nonsense (and egos) at the bottom of the barrel and out of the way. As an up-and-coming developer with so much to learn, I am grateful for each and every one of their patient contributions. I wish I could come up with a catchy/funny sign-off that makes everybody feel good, but I lack the funny bone that so many of the people on this site seem to have been born with. Instead, I can only leave my gratitude and a promise that as long as the community stays this great, I'll stay an avid reader...and one day be experienced enough to carry the torch of contribution. Sincerely, Daniel the Intern

• DDD/NHibernate Use of Aggregate root and impact on web design - ex. Editing children of aggregate ro

  - by pbrophy

  Hopefully, this fictitious example will illustrate my problem: Suppose you are writing a system which tracks complaints for a software product, as well as many other attributes about the product. In this case the SoftwareProduct is our aggregate root and Complaints are entities that only can exist as a child of the product. In other words, if the software product is removed from the system, so shall the complaints. In the system, there is a dashboard like web page which displays many different aspects of a single SoftwareProduct. One section in the dashboard, displays a list of Complaints in a grid like fashion, showing only some very high level information for each complaint. When an admin type user chooses one of these complaints, they are directed to an edit screen which allows them to edit the detail of a single Complaint. The question is: what is the best way for the edit screen to retrieve the single Complaint, so that it can be displayed for editing purposes? Keep in mind we have already established the SoftwareProduct as an aggregate root, therefore direct access to a Complaint should not be allowed. Also, the system is using NHibernate, so eager loading is an option, but my understanding is that even if a single Complaint is eager loaded via the SoftwareProduct, as soon as the Complaints collection is accessed the rest of the collection is loaded. So, how do you get the single Complaint through the SoftwareProduct without incurring the overhead of loading the entire Complaints collection?

• How to use a specific PDF IFilter

  - by dthrasher

  I'm trying to extract text from PDF files using an iFilter. The Adobe PDF iFilter that is distributed with Adobe Reader is awful, returning HRESULT E_FAIL messages for many PDF documents. The FoxIt PDF IFilter works beautifully on virtually all of the PDFs I've been using for testing. The problem is that every time the Adobe Updater runs, it replaces the awesome FoxIt IFilter with the crappy Adobe IFilter. I've been using the LoadIFilter method to get the registered IFilter for PDF files. Is there a way to force the Win32 API to load the FoxIt IFilter instead of the Adobe IFilter? NOTE: This question about determining which IFilters are installed asks a related -- but not identical -- question.

• Using Google Maps v3, PHP and Json to plot markers

  - by bateman_ap

  Hi, I am creating a map using the new(ish) v3 of the Google Maps API I have managed to get a map displaying using code as below: var myLatlng = new google.maps.LatLng(50.8194000,-0.1363000); var myOptions = { zoom: 14, center: myLatlng, mapTypeControl: false, scrollwheel: false, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("location-map"), myOptions); However I now want to add a number of markers I have stored in a PHP array. The Array currently looks like this if I print it out to screen: Array ( [0] => Array ( [poiUid] => 20 [poiName] => Brighton Cineworld [poiCode] => brighton-cineworld [poiLon] => -0.100450 [poiLat] => 50.810780 [poiType] => Cinemas ) [1] => Array ( [poiUid] => 21 [poiName] => Brighton Odeon [poiCode] => brighton-odeon [poiLon] => -0.144420 [poiLat] => 50.821860 [poiType] => Cinemas ) ) All the reading I have done so far suggests I turn this into JSON by using json_encode If I run the Array though this and echo it to the screen I get: [{"poiUid":"20","poiName":"Brighton Cineworld","poiCode":"brighton-cineworld","poiLon":"-0.100450","poiLat":"50.810780","poiType":"Cinemas"},{"poiUid":"21","poiName":"Brighton Odeon","poiCode":"brighton-odeon","poiLon":"-0.144420","poiLat":"50.821860","poiType":"Cinemas"}] The bit now is where I am struggling, I am not sure the encoded array is what I need to start populating markers, I think I need something like the code below but not sure how to add the markers from my passed through JSON var locations = $jsonPoiArray; for (var i = 0;i < locations.length; i += 1) { // Create a new marker };

• How do I parse JSON from a Java HTTPResponse?

  - by Joe Ludwig

  I have an HttpResponse object for a web request I just made. The response is in the JSON format, so I need to parse it. I can do it in an absurdly complex way, but it seems like there must be a better way. Is this really the best I can do? HttpResponse response; // some response object Reader in = new BufferedReader( new InputStreamReader(response.getEntity().getContent(), "UTF-8")); StringBuilder builder= new StringBuilder(); char[] buf = new char[1000]; int l = 0; while (l >= 0) { builder.append(buf, 0, l); l = in.read(buf); } JSONTokener tokener = new JSONTokener( builder.toString() ); JSONArray finalResult = new JSONArray( tokener ); I'm on Android if that makes any difference.

• Horizontal UITableView

  - by imran

  I want implement a layout in my ipad application that has a uitable view that scrolls left and right rather then up and down : So rather than row 1 row 2 row 3 ( scrolling vertically ) It would be : row 1, row2, row 3 (scrolling horizontally ) I've seen that UItableView is designed to only do vertical scrolling so doing a transform does not give the desired effect. Is there a standard way to do this taking advantage of a datasource provider like uitableview provides? I basically want to do somthing similar to what the BBC News reader app ( http://itunes.apple.com/us/app/bbc-news/id364147881?mt=8 ) on the Ipad does with the list of stories to select from. Thanks

• Using a UITextView in a UITableViewCell with a UIKeyboard

  - by Luther Baker

  I have a simple UITableView that has two cells. Cell 0:0 consists of a UITextField we'll call the title and Cell 0:1 consists of a UITextView we'll simply call a note. Cell 0:0 (the text field) is a standard size, one row cell. I'm therefore trying to fill the rest of the screen up with Cell 0:1 so I return a larger height for it. This all displays just fine and I'm using most of the iPhone real estate pretty efficiently at this point. Now, when a user wants to edit one of these cells, he need only click in the appropriate textfield or textview. If a user clicks in the textfield of Cell 0:0, all is well and the keyboard slides up from the bottom. My problem occurs when a user clicks into the the textview (Cell 0:1). No matter what I try, the UITableView wants to slide the entire table view up and that generally put the UITextView in Cell 0:1 halfway out of sight. What I want to do is two fold, I'm registered for when the keyboard will appear and in that method, I'd like to shrink the UITextView in Cell 0:1 as well as shrink the UITableViewCell itself so that the keyboard doesn't have to be smart and think it has to slide the UITableViewCell into view. Unfortunately, no matter what I try, the UITableView slides up. I just want the UITableView to stand still and I want the cell to animate up/shorter with the keyboard. It appears that, by the time the keyboard is actually animating into the screen - it is to late to adjust the cell size. The UIKit has already made up it's mind that it is going to scroll the UITableView.

• Contact-app like scrollinglist on android

  - by Alxandr

  I'm writing my first android app (I'm a noob at android, but decent at java). The first screen of the app consists of a huge list (about 1.5K items) of Manga-objects. The code I use is as following: main.xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <ListView android:layout_height="fill_parent" android:layout_width="fill_parent" android:id="@+id/android:list"></ListView> <TextView android:layout_height="fill_parent" android:layout_width="fill_parent" android:text="@string/list_no_items" android:id="@+id/android:empty"></TextView> </LinearLayout> row.xml: <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip" xmlns:android="http://schemas.android.com/apk/res/android"> <ImageView android:id="@+id/icon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_marginRight="6dip" android:src="@drawable/icon" /> <LinearLayout android:orientation="vertical" android:layout_width="0dip" android:layout_weight="1" android:layout_height="fill_parent"> <TextView android:id="@+id/toptext" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:gravity="center_vertical" /> <TextView android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:id="@+id/bottomtext" android:singleLine="true" android:ellipsize="marquee" /> </LinearLayout> </LinearLayout> Then I have a adapter which basically takes a Manga-object and puts it's name in the rows toptext, and it's latest updated date in the bottomtext. However, (this might be caused by the virtualization of the unit though), the result is really slow. Scrolling the list takes forever and you can only scroll small peaces of the time. How can I make the list work like the one in the contacts-app? So that when you start scrolling a handle pops out at the right side of the screen, and when you drag it letters shows up as of how far you've scrolled (the list is sorted alphabetically), and also, is there a way I could improve the performance of the list?

• Scrolling issues with GridView in Android

  - by Jared Thigpen

  I am having weird scrolling issues in my pretty simple GridView. Each item in the Grid is simply and ImageView and a TextView. The activity itself is simply an application selector. It looks like a rough version of the basic App Tray in Android. The issue is that after spending some times scrolling through my view, it will inevitably allow me to continue scrolling past the top row of icons, to a blank screen, and the scroll bar will disappear, leaving me stuck. It doesn't happen every time I go to the top of the view, only sometimes, and usually only after some excessive scrolling. If I happen to notice the problem and catch it before the top row disappears off the bottom of the screen, I can usually scroll back through the view and spot some icons missing. There are empty spaces in the grid, and I can only assume that those icons have been moved to some bizarre position, which is allowing the view to scroll past the top. This is my first Android app beyond a basic Hello World, so it's likely that I've just screwed up something in my layout files. I also realize that this is probably a pretty confusing description, so I'm hoping someone has experienced this and my search abilities simply were unable to find it. I can post my layout files or other code if someone thinks that's useful. Oh, and the program is built against 1.5, but is running on 2.2 (whatever state of 2.2 that was that snuck out last week) on my phone. I don't have enough apps to test this on an emulator, but could probably set something up if someone felt it necessary. Thanks in advance for any help on the issue.

  Hi guys, long time reader, first time poster. (A link to this schema is located here) http://www.weeshsoft.com/pix/DatabasePic.jpg I'm trying to get all LanguageEntries from a database for a given category.categoryName and languageset.languageSetName e.g. NSFetchRequest* fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"LanguageEntry" inManagedObjectContext:del.managedObjectContext]; [fetchRequest setEntity:entity]; NSString* predicateString = [NSString stringWithFormat:@"Category.categoryName = %@ AND LanguageSet.languageSetName = %@", @"Food", @"English####Spanish"]; fetchRequest.predicate = [NSPredicate predicateWithFormat:predicateString]; NSError *error = nil; NSArray* objects = [del.managedObjectContext executeFetchRequest:fetchRequest error:&error]; This always returns 0 objects. If I set the predicate string to match on one relationship (e.g. Category.categoryName = Food or languageSet.languageSetName = English####Spanish) it will return data.

• Pop-up modal with UITableView on iPhone

  - by Meltemi

  I need to pop up a quick dialog for the user to select one option in a UITableView from a list of roughly 2-5 items. Dialog will be modal and only take up about 1/2 of screen. I go back and forth between how to handle this. Should I subclass UIView and make it a UITableViewDelegate & DataSource? I'd also prefer to lay out this view in IB. So to display I'd do something like this from my view controller (assume I have a property in my view controller for DialogView *myDialog;) NSArray* nibViews = [[NSBundle mainBundle] loadNibNamed:@"DialogView" owner:myDialog options:nil]; myDialog = [nibViews objectAtIndex:0]; [self.view addSubview:myDialog]; problem is i'm trying to pass owner:myDialog which is nil as it hasn't been instantiated...i could pass owner:self but that would make my view controller the File's Owner and that's not how that dialog view is wired in IB. So that leads me to think this dialog wants to be another full blown UIViewController... But, from all I've read you should only have ONE UIViewController per screen so this confuses me because I could benefit from viewDidLoad, etc. that come along with view controllers... Can someone please straighten this out for me?

• Android: SharedPreference: Defaults not set at startup...

  - by Allan

  I have Listpreferences in my app. They don't appear to be setting to their defaults right after installation - they appear to be null. I'm trying to figure out why my default preferences are not being set right after installation. In my main code I have: SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this); InUnits = sp.getString("List1", "defValue"); InAngs = sp.getString("List2", "defValue"); OutUnits = sp.getString("List3", "defValue"); OutAngs = sp.getString("List4", "defValue"); Right after the above code executes, each variable contains "defValue" instead of the actual values I have assigned in my ListPreference below. My preference xml file is called, "settings.xml". Here's what one of the ListPreferences there looks like: <ListPreference android:key="List1" android:title="Input: Alph" android:summary="Choose Alph or Ralph" android:entries="@array/inputAlph" android:entryValues="@array/input_Alph_codes" android:dialogTitle="Input Alph" android:defaultValue="ININ"/> Here's what some of my strings.xml file looks like: <string-array name="inputUnits"> <item>Alph</item> <item>Ralph</item> </string-array> <string-array name="input_Alph_codes"> <item>ININ</item> <item>INMM</item> </string-array> When I go to menu, and then settings, I can see my defaults checked (radiobuttoned). Then when I go back from the settings menu to my main screen - all is well - for life! ...then each var above is assigned the proper default value. This only happens when I first install my app on the phone. After I go to the settings screen once and then right out of it, the app is fine and accepts any setting changes. By the way, as you can see, "List1" is the android:key within a file called settings.xml in my res/xml folder.

• UIView animation VS core animation

  - by Tom Irving

  I'm trying to animate a view sliding into view and bouncing once it hits the side of the screen. A basic example of the slide I'm doing is as follows: // The view is added with a rect making it off screen. [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:0.07]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)]; [theView setFrame:CGRectMake(-5, 0, theView.frame.size.width, theView.frame.size.height)]; [UIView commitAnimations]; More animations are then called in the didStopSelector to make the bounce effect. The problem is when more than one view is being animated, the bounce becomes jerky and, well, doesn't bounce anymore. Before I start reading up on how to do this in Core Animation, (I understand it's a little more difficult) I'd like to know if there is actually an advantage using Core Animation rather than UIView animations. If not, is there something I can do to improve performance?
