• how mount userdata.img or userdata-qemu.img in osx

  - by misbell

  Disk Utility in OSX easily mounts an SD Card image as a device, but not so the other img files. I want to get the database I just created in the Android Emulator off the drive and into my osx file system. I updated my system with qemu using macports but no combination I try succeeds. Anyone figured out how to do this? Obviously one way I can do this is run the app on my phone than mount the phone as a USB drive. But I don't wanna. I wanna get it off the drive the emulator uses :-) Thanks in advance, folks. Michael

• Symbol not found: _OBJC_CLASS_$_UIPopoverController

  - by Paul Peelen

  Hi, I am having problems with my universal app. I have set the Base SDK to iPhone 3.2 and set the target to 3.1. I have moved the files that are using the UIPopoverController to their own files and they shouldn't be loaded when loading the app on the iPhone. Still, when I build my app I get the following error when I build and debug to my device: dyld: Symbol not found: _OBJC_CLASS_$_UIPopoverController Referenced from: /var/mobile/Applications/B3B90643-92DC-4E5C-8B2F-83A42D6D57E0/citybikes.app/citybikes Expected in: /System/Library/Frameworks/UIKit.framework/UIKit in /var/mobile/Applications/B3B90643-92DC-4E5C-8B2F-83A42D6D57E0/citybikes.app/citybikes I really hope someone can help me.

• Entity Framework: How to bind related products

  - by Waheed

  I am using the following Linq query from p in Product.Include("ProductDetails.Colors") where p.ProductID.Equals(18) select p; And then using the result of this query to bind the GridView. The productDetails are bind to the grid fine, but the Colors are not bind. To bind colors i am using <%# Eval("Colors.CategoryName") %.

• iPhone SDK "loading" on Titanium Developer

  - by raulriera

  Hi, I have tried this question on the site of Titanium and several tweets to their account, but they either ignore me or refuse to answer. I want to start using their framework, but for some reason the iPhone SDK is always "loading" when in the "TEST & PACKAGE" tab. Have you guys found a fix for this? I have: Snow Leopard 10.6.3 Titanium Developer 1.2.1 iPhone SDK 3.2 All the certificates "blah blah" from Apple because I am able to test and deploy apps on my device using XCode. Help please :)

• Python: split files using mutliple split delimiters

  - by donalmg

  Hi, I have multiple CSV files which I need to parse in a loop to gather information. The problem is that while they are the same format, some are delimited by '\t' and others by ','. After this, I want to remove the double-quote from around the string. Can python split via multiple possible delimiters? At the minute, I can split the line with one by using: f = open(filename, "r") fields = f.readlines() for fs in fields: sf = fs.split('\t') tf = [fi.strip ('"') for fi in sf] Any suggestions are welcome.

• Problems with video playback in iPad.

  - by Leg10n

  I'm trying to implement a MPMoviePlayerView but I can't play the video files, I don't have a device yet to try it on, now I'm testing with simulator, I don't know if this is the cause. So far I've been able to present the view and it shows the first frame of the video, but if I click play, it doesn't play I can move the progress bar and it shows the images, but there's no movement, it stays still. Has anyone experienced something like this? The code of my UIViewController goes like this: NSURL *movieURL=[NSURL fileURLWithPath:@"video.mp4"]; MPMoviePlayerViewController *playerView=[[MPMoviePlayerViewController alloc] initWithContentURL:movieURL]; [self presentMoviePlayerViewControllerAnimated:playerView]; As I said, it shows up, I can move the progress bar back and forth, I see a still image, but no movement. Am I missing something here? or is it the simulator? Thank you

• SAT Thread and Process output capture in c#

  - by alex

  Hi: This is a strange problem I encountered. I have an window application written in c# to do testing. It has a MDI parent form that is hosting a few children forms. One of the forms launch test cripts by creating processes and capture the scripts output to a text box. Another form open serial port and monitoring the status of the device I am working on(like a shell). If I ran both of them together, the output of the script seems only appear in the text box after the test is done. However, If I don't open the serial port form, the output of the script is captured in real time. Does anyone knows what's causing the problem? I notice the onDataReceived even handler for serial port form has a [SAThread] header to it. Will this cause the serial port thread having higher priority than other processes? Thanks in advance.

• Silverlight: DataContractSerializer cannot handle read only collection properties

  - by moonground.de

  Hey Stackoverflowers :) For our Silverlight Project (SL4) I'm using a Model which might contain Lists (IList<AnotherModel>). According to good practice and rule CA2227:CollectionPropertiesShouldBeReadOnly the IList properties don't have a public setter. We serialize the Model using the DataContractSerializer which is working. But when I try to deserialize, a SecurityException is thrown by DataContractSerializer's ReadObject(Stream) Method, complaining that the target property (pointing to the IList property) cannot be set due to a missing public setter. Since the DataContractSerializer is sealed and neither extendable nor flexible so I currently see no chance to add some kind of additional rules which allow to deserialize the ILists using a foreach-loop on Add() method or some other method of transferring the collection items. I've also tried to dig into DataContractSerializer source (using Reflector) to create a little fork but it looks like i'd have to dig very deep and replicating whole serialization classes doesn't seem to be a viable solution. Do you see another chance to serialize a List with no public setter using the DataContractSerializer? Thank you very much in advance for your ideas! Thomas

• the scope of a pointer ???

  - by numerical25

  Ok, so I did find some questions that were almost similar but they actually confused me even more about pointers. http://stackoverflow.com/questions/2715198/c-pointer-objects-vs-non-pointer-objects-closed In the link above, they say that if you declare a pointer it is actually saved on the heap and not on the stack, regardless of where it was declared at. Is this true ?? Or am I misunderstanding ??? I thought that regardless of a pointer or non pointer, if its a global variable, it lives as long as the application. If its a local variable or declared within a loop or function, its life is only as long as the code within it.

• How to delete SMS from inbox in android programmatically?

  - by dmyung

  Just thought I'd ping this community to see if there's any knowledge on this issue. On android phones SMS messages registered to applications also get sent to the device's inbox. However to prevent clutter, it'd be nice to be able to remove app specific SMS mesg's from the inbox to reduce the potential overflow of those messages. Questions on other google groups on getting a definitive answer on a programmatic way to delete SMS messages from the android inbox don't seem to be pressing. So the scenario: Android App startup. register SMS message types X,Y and Z messages P,Q,X,Y,Z stream in over the course of time, all deposited in inbox Android app detects receipt of X,Y,Z (presumably as part of the program interrupt event) process X,Y,Z Desirement!!! X,Y,Z are deleted from android inbox Has it been done? Can it be done?

• OAuth Callback procedure for mobile devices

  - by behrk2

  Hello, I am designing a Netflix Application for BlackBerry mobile devices. I am currently working on the OAuth. I am at the point where I can generate a Netflix login page in an embedded browser field in my application. After the user signs in, Netflix will send the user from the login page to a specified callback url. The callback url will also contain an authorized token, which is then needed to send back to Netflix. My question is: How am I supposed to do this on a mobile device? Is there a procedure set in place? I am unsure how I can extract the authorized token from the callback URL and send it back to my application. From my research, it does not appear that Netflix will provide a PIN/verifier for the user to then type into the application... Does anyone have any ideas? Thanks...

• Looping to provide multiple lines in linechart (django-googlecharts)

  - by mighty_bombero

  Hi, I'm trying to generate some charts using django-googlecharts. This works fine for rather static data but in one case I would like to render a different number of lines, based on a variable. I tried this: {% chart %} {% for line in line_data %} {% chart-data line %} {% endfor %} {% chart-size "390x200" %} {% chart-type "line" %} {% chart-labels days %} {% endchart %} Line data is a list containing lists. The template code fails with "Caught an exception while rendering: max() arg is an empty sequence". I guess the problem is that I try to loop over templatetags. What approach could be used here? Or am I completely missing something? Is this doable using inclusion tags? Thanks for your help.

• C# System.Threading.Timer and its state object

  - by Captain NedD

  I am writing a C# program that uses System.Threading.Timer to timeout on a UDP socket ReceiveAsync call. My program polls a remote device, sending a UDP packet and expecting one in return. I use the timer in one shot mode calling Timer.Change every time I want a new timeout period. For every occurance of a timeout I'd like the timeout handler to have a different piece of information. If I change the object I pass to the Timer on creation it doesn't seem to change when the handler executes. Is the only way to do this to destroy the timer and create a new one? Thanks,

• CUDA: cudaMemcpy only works in emulation mode.

  - by Jason

  I am just starting to learn how to use CUDA. I am trying to run some simple example code: float *ah, *bh, *ad, *bd; ah = (float *)malloc(sizeof(float)*4); bh = (float *)malloc(sizeof(float)*4); cudaMalloc((void **) &ad, sizeof(float)*4); cudaMalloc((void **) &bd, sizeof(float)*4); ... initialize ah ... /* copy array on device */ cudaMemcpy(ad,ah,sizeof(float)*N,cudaMemcpyHostToDevice); cudaMemcpy(bd,ad,sizeof(float)*N,cudaMemcpyDeviceToDevice); cudaMemcpy(bh,bd,sizeof(float)*N,cudaMemcpyDeviceToHost); When I run in emulation mode (nvcc -deviceemu) it runs fine (and actually copies the array). But when I run it in regular mode, it runs w/o error, but never copies the data. It's as if the cudaMemcpy lines are just ignored. What am I doing wrong? Thank you very much, Jason

• Disable scrolling in an iPhone web application?

  Is there any way to completely disable web page scrolling in an iPhone web app? I've tried numerous things posted on google, but none seem to work.

• How to set a checkbox to checked state in a ListView using Autohotkey

  - by Itay Levin

  Hi, I am writing a Autohotkey script that need to 'check' and 'uncheck' checkboxes defined inside a listViewControl. I think the way to do it is using a SendMessage to the listview (or maybe to the listview item itself?) using the LVM_SETITEMSTATE parameter but i don't know the exact format...anyone have any idea? SendMessage, LVM_SETITEMSTATE, 1000, SysListView321 i think that 1000 means that the checkbox will be checked and 2000 means that he will be unchecked. do i need to do a loop for each ListViewItem? I had also tried to use the LV_Modify(0, "+Checked") But it doesnt seems to work also. To emphasize the problem, I am not creating my own List View, i'm trying to manipulate the state of an exisiting application ListView.... (i'm running an installer and using the AutoHotKey script i press the next buttons on each of the screens, but in this screen i need to first select all the components and only then move to the next screen) Any AutoHotKey Experts in here?

• iPad UISplitView initial state in portrait: how to display popover controller widget?

  - by Patrick Linskey

  Hi, I'm working on an iPad app that uses a UISplitView. Inspired by http://blog.blackwhale.at/2010/04/your-first-ipad-split-view-application/, I display a button in my detail view when in portrait mode that shows the popover controller. This works great. However, the appropriate UISplitViewControllerDelegate message is only sent when the device rotates. So, when the app first loads (in portrait mode), my navigation button is not visible. Is it possible to somehow convince the UISplitViewController to send that message on load or something, or do I need to re-implement my own popover logic to get things working? Thanks, -Patrick

• Why the CLLocationManager delegate is not getting called in iPhone SDK 4.0 ???

What is the reason ?? I am getting frustrated ...... Thanks....

• Linq To Objects Auto Increment Number

  - by Nathan

  This feels like a completely basic question, but, for the life of me, I can't seem to work out an elegant solution. Basically, I am doing a Linq Query creating a new object from the query. In the new object, I want to generate a auto-incremented number to allow me to keep a selection order for later use (named Iter in my example). Here is my current solution that does what I am needing: Dim query2 = From x As DictionaryEntry In MasterCalendarInstance _ Order By x.Key _ Select New With {.CalendarId = x.Key, .Iter = 0} For i = 0 To query2.Count - 1 query2(i).Iter = i Next Is there a way to do this within the context of the linq query (so that I don't have to loop the collection after the query)? Thanks!

• Why does CLLocationManager returns null locations on the iphone SDK 4 beta in the Simulator?

  - by Rigo Vides

  Hi everyone, I have this piece of code: - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { NSLog(@"Manager did update location!!"); self.currentLocation = newLocation.description; } I have this code inside a class that conforms to the CLLocationManagerDelegate. I tested earlier in sdk 3.0 and works nice (on both simulator and device). I'm testing this class on the SDK 4, in the simulator, but it gives null as a newLocation. I can't even get the NSLog for the first call. I checked other app where I use the location framework and it doesn't work either. I implemented the locationManager:didFailWithError: message also, wich is never called. Can anyone please confirm that the simulator can't do any CLLocationManager capabilities? (a link where the bug is reported as a known issue will be awesome). Is there a way to fix this? Thanks in advance.

• Emacs: selective c-auto-newline

  - by Yktula

  When c-auto-newline is set to non-nil, it re-indents the current line and inserts a carriage return and then indents the new line. However. I'm using 1TBS indent-style, which means if/else statements are made like this: if (n == 1) { exit(EXIT_SUCCESS); } else { perror("n"); } Also, I write do/while write loops like this: do { printf("%d\n", n++); } while (n < 64); As such, while I do want a newline automatically inserted after every opening brace and semicolon, I don't want newlines to be automatically inserted after an if statement or do loop is concluded with a closing brace. How can I have GNU Emacs (23.2.1, *nix) selectively insert newlines like that? Along the same lines, can I have Emacs insert an opening brace, a newline, and a closing brace on another newline, while putting the cursor in the middle of the two braces after closing parentheses following an if statement, function declaration, and the like?

• LiNQ to Entities, Include less

  - by Freddy

  Hi, If you are making a LinQ to entities expression for ClassA where A has a relation to ClassB like this: var temp = from p in myEntities.ClassA.Include("ClassB") where ... select p; You will get a set of ClassA:s with the reference to ClassB loaded. The thing in my case is that I dont really need to load ALL the ClassB-references, just a few of them. But I dont want to loop through the list of ClassA:s and load them individually, i want my database operations to be fewer and bigger instead of reading small chunks here and there. Is it possible to put some kind of restrictions on which references to include or do you have to accept this all or nothing style?
