  • iPhone adding a timer to an app

    - by Rob J
    How would I go about adding a simple 2 minute timer to my app in almost the exact same way that the clock app does? I just want the user to click start and have the timer start displaying the timer counting down from 2:00 and beep when it hits 0:00.

  • Adding cancel ability and exception handling to async code.

    - by Rob
    I have this sample code for async operations (copied from the interwebs) public class LongRunningTask { public LongRunningTask() { //do nowt } public int FetchInt() { Thread.Sleep(2000); return 5; } } public delegate TOutput SomeMethod<TOutput>(); public class GoodPerformance { public void BeginFetchInt() { LongRunningTask lr = new LongRunningTask(); SomeMethod<int> method = new SomeMethod<int>(lr.FetchInt); // method is state object used to transfer result //of long running operation method.BeginInvoke(EndFetchInt, method); } public void EndFetchInt(IAsyncResult result) { SomeMethod<int> method = result.AsyncState as SomeMethod<int>; Value = method.EndInvoke(result); } public int Value { get; set; } } Other async approaches I tried required the aysnc page attribute, they also seemed to cancel if other page elements where actioned on (a button clicked), this approach just seemed to work. I’d like to add a cancel ability and exception handling for the longRunningTask class, but don’t erm, really know how.

  • How to use LINQ for CRUD with a simple SQL table?

    - by Rob Ferno
    Every LINQ blog I found there seemed around 2 years old, I understand the syntax but need more direction on creating the SQL mapping and context classes. I just need to use LINQ for 2 SQL tables I have, nothing complicated. Do folks write the SQL mapping classes by hand for such cases or is there a decent tool for this? Can someone point me in the right direction?

  • Leftover Nav Bar in Landscape View

    - by Rob Bonner
    Hello, I am working to force a view into landscape mode, and have picked up all kinds of cool tips to make this happen, but am stuck on one item that is left on the screen. I have my XIB file laid out in landscape, and in my code I create the view controller normally: RedeemViewController *aViewController = [[RedeemViewController alloc] initWithNibName:@"RedeemViewController" bundle:nil]; aViewController.hidesBottomBarWhenPushed = YES; aViewController.wantsFullScreenLayout = YES; [[self navigationController] pushViewController:aViewController animated:YES]; Inside the controller viewDidLoad I complete the following: [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight]; [[self navigationController] setNavigationBarHidden:YES animated:YES]; [UIView beginAnimations:@"View Flip" context:nil]; [UIView setAnimationDuration:.75]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; if (self.interfaceOrientation == UIInterfaceOrientationPortrait) { self.view.transform = CGAffineTransformIdentity; self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(90)); self.view.bounds = CGRectMake(0.0, 0.0, 480, 320); } [UIView commitAnimations]; What I end up with is a perfectly rotated view, with a grey vertical bar on the left side (see pic). So to the question, how do I get rid of the bar? Edit: I am pretty sure this is the navigation bar that is not being hidden. This is a duplicate of another post, with some modified code, the other question was being answered with the bug.

  • How to replicate Google "Hangouts On Air" stream combining functionality?

    - by Rob Olmos
    I've been researching this one for quite a bit but haven't found any solid leads. I have a Wowza/Flash app with video chatroom functionality and would like to combine the streams server-side into one video/audio stream in order to be sent to a live Youtube channel. I've found a couple projects such as jMixer and some helpful keywords such as "vision mixer" to help with my search but looking for any previous experience or new ideas. The other option is building something like it myself with a commercial video decoding/encoding library to raw frames, stitching the frames together, then encoding it. I was originally going down this route but put project on hold. What are some ideas, keywords, or existing software (open source preferred) to take those live streams and combine them into one in real-time? Or is coding it myself the required route? Thanks!

  • MySQL Query For Copying Contents Into Another Field, Same Row

    - by Rob Adler
    Is there a single query (subqueries in it are allowed) where I can copy the content of one field into another field, per row. Example: price, and priceBackup Records: 45.55 47.77 45.55 copies into priceBackup for that specific row, 47.77 copies into priceBackup for that specific row. I do have a primary key, auto increment on it under 'id'. Thanks guys!

  • Dynamic picture that displays the visitors IP address?

    - by Rob
    I see this a lot now, jpg files displaying your IP address. To you of course, not to others, they would see their own For example: How is this even possible? If this is possible, would it be possible to log an IP into a MySQL database from the picture as well? Is my IP getting logged when I view this?

  • iphone selecting a row to change view

    - by Rob J
    I have created the view Controllers and attached those to control their respective views. I can't figure out how to make the following code to go the right views though. (This is in the root view controller:) - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { RunViewController *runViewController = [[RunViewController alloc] initWithNibName:@"RunView" bundle:[NSBundle mainBundle]]; CalcViewController *calcViewController = [[CalcViewController alloc] initWithNibName:@"CalcView" bundle:[NSBundle mainBundle]]; PushViewController *pushViewController = [[PushViewController alloc] initWithNibName:@"PushView" bundle:[NSBundle mainBundle]]; SitViewController *sitViewController = [[SitViewController alloc] initWithNibName:@"SitView" bundle:[NSBundle mainBundle]]; TimerViewController *timerViewController = [[TimerViewController alloc] initWithNibName:@"TimerView" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:runViewController animated:YES]; [runViewController release]; [self.navigationController pushViewController:pushViewController animated:YES]; [pushViewController release]; [self.navigationController pushViewController:sitViewController animated:YES]; [sitViewController release]; [self.navigationController pushViewController:timerViewController animated:YES]; [timerViewController release]; [self.navigationController pushViewController:calcViewController animated:YES]; [calcViewController release]; runViewController = nil; pushViewController = nil; sitViewController = nil; timerViewController = nil; calcViewController = nil; } Each time I select any of the rows in the table - all of the views come up. How do I arrange them to only open the view that it is supposed to?

  • Symfony: Pre filtering submitted values before/after validation

    - by Rob
    Hi All I've been scouring the net and i have found nothing! I am using symfonys form framework to build a simple 'Create' form. Validation is fine. However i'd like to pre-filter my submitted values, so adding ucfirst, strtoupper, and the like. I'm not sure if im missing something crucial here, but the way i see it is the only way to do this would be to create my own custom validators and utilizing the doClean method, which seems daft since i'd have hundreds of validators for each php function! Hope you guys can help, i've been crawling through source code, api's, numerous books and blogs and i haven't found a thing :( Either it's impossible, or it's really easy, i hope its the latter!

  • Proper programming procedure?

    - by Rob
    I am creating a scoring application which is dependent upon what a user selects at the beginning menu. Example: If a user clicks 18, I want it to base itself off 18 holes of golf. If a user clicks 9, I want it to base itself off 9 holes of golf. Is it better to create a separate class for the code for 9 holes, and then another for 18 holes and then launch whichever depending on what the user selects? Or should I keep everything in 1 file and use a global variable to define different parameters? Still very new to android programming (or programming in general) so not sure of the proper "etiquette" if you will... Also what would be the pro's and con's of doing it either way? (If any) Thanks in advance!

  • DateTime.ParseExact string format exception.

    - by Rob Ferno
    I am trying to convert a string into datetime with the following C# code, DateTime dTo = DateTime.ParseExact(dateTo, "mm/dd/yyyy", CultureInfo.InvariantCulture); eachtime I pass dateTo as 1/1/2010 it fails, instead it needs the string to be 01/01/2010. What string format should I use to support both 01/01/2010 and 1/1/2010?

  • Is it possible to resolve domain names to an IP address with PHP?

    - by Rob
    Well, very simple question. So that's good news for you, I guess. More thorough explanation: I have a PHP script allowing me to add urls to a database. I want the script to resolve the url to an IP address as well, to store that, too. However, some of the URLs are like this: http://111.111.111.111/~example/index.php So it also needs to work with that. I'm not SURE that this is possible, but it only makes sense it would be. So: Is it possible, and if so, how?

  • PHP Arrays: Pop an array of single-element arrays into one array.

    - by Rob Drimmie
    Using a proprietary framework, I am frequently finding myself in the situation where I get a resultset from the database in the following format: array(5) { [0] => array(1) { ["id"] => int(241) } [1] => array(1) { ["id"] => int(2) } [2] => array(1) { ["id"] => int(81) } [3] => array(1) { ["id"] => int(560) } [4] => array(1) { ["id"] => int(10) } } I'd much rather have a single array of ids, such as: array(5) { [0] => int(241) [1] => int(2) [2] => int(81) [3] => int(560) [4] => int(10) } To get there, I frequently find myself writing: $justIds = array(); foreach( $allIds as $id ) { $justIds[] = $id["id"]; } Is there a more efficient way to do this?

  • Simple iPhone tally method question

    - by Rob
    Just trying to create a simple method that counts up 1 on the tally when the button is pressed. My knowledge is extremely limited and I am pretty sure that my problem is somewhere in the method implementation: -(IBAction) updateTally:(id) sender { NSString *text; int total = 0; total = total + 1; text=[[NSString alloc] initWithFormat: @"%i", total]; lblTally.text = text; } I have done the necessary interface declarations for the lblTally UILabel and the updateTally method. I suspect that there is some sort of an NSString/int/%i/%@ mixup that I am making but I'm not sure how to fix it. When I run the program as it currently is it displays a 0 in the lblTally label field on the iphone. When I press the button it then displays a 1 in that field. However, if I continue to press the button - nothing happens.

  • Hibernate one-to-one: getId() without fetching entire object

    - by Rob
    I want to fetch the id of a one-to-one relationship without loading the entire object. I thought I could do this using lazy loading as follows: class Foo { @OneToOne(fetch = FetchType.LAZY, optional = false) private Bar bar; } Foo f = session.get(Foo.class, fooId); // Hibernate fetches Foo f.getBar(); // Hibernate fetches full Bar object f.getBar().getId(); // No further fetch, returns id I want f.getBar() to not trigger another fetch. I want hibernate to give me a proxy object that allows me to call .getId() without actually fetching the Bar object. What am I doing wrong?

  • Is it possible to write a SQL query to return specific rows, but then join some columns of those row

    - by Rob
    I'm having trouble wrapping my head around how to write this query. A hypothetical problem that is that same as the one I'm trying to solve: Say I have a table of apples. Each apple has numerous attributes, such as color_id, variety_id and the orchard_id they were picked from. The color_id, variety_id, and orchard_id all refer to their respective tables: colors, varieties, and orchards. Now, say I need to query for all apples that have color_id = '3', which refers to yellow in the colors table. I want to somehow obtain this yellow value from the query. Make sense? Here's what I was trying: SELECT * FROM apples, colors.id WHERE color_id = '3' LEFT JOIN colors ON apples.color_id = colors.id

  • ReSharper 5 disable resolve view

    - by Rob
    I just did a fresh installation of Visual Studio 2010 Ultimate and ReSharper 5. But now ran into the following situation; return View("~/Plugin/Plugin.Product.dll/Plugin.Product.Views.CreateProduct.ascx"); From a controller i'm returning a view a shown above. ReSharper 5 is trying to resolve this view, but can't find it. Which is explainable in my situation. What i want is to disable the option for ReSharper to try and resolve the views. Is this possible?

  • Configure Symfony for use with Memcached

    - by Rob Wilkerson
    I have 2 Symfony applications (1 using 1.2.x, another using 1.4.x and both using Propel) that need to share some specific session information. Although I have no experience with memcached, my sense--after some reading--is that it may be able to serve as an external (FAST) repository that each app could read and write to. Unfortunately, I can't find much information about how to use it with Symfony in any capacity, much less in the quasi-cache, quasi-messaging server I'm envisioning. My questions, I suppose, are: Am I mistaken in believing that memcached be used in this manner and access by multiple systems? How can I configure Symfony to access a memcached repository? Thanks.

  • Git Svn dcommit error - restart the commit

    - by Rob Wilkerson
    Last week, I made a number of changes to my local branch before leaving town for the weekend. This morning I wanted to dcommit all of those changes to the company's Svn repository, but I get a merge conflict in one file: Merge conflict during commit: Your file or directory 'build.properties.sample' is probably out-of-date: The version resource does not correspond to the resource within the transaction. Either the requested version resource is out of date (needs to be updated), or the requested version resource is newer than the transaction root (restart the commit). I'm not sure exactly why I'm getting this, but before attempting to dcommit, I did a git svn rebase. That "overwrote" my commits. To recover from that, I did a git reset --hard HEAD@{1}. Now my working copy seems to be where I expect it to be, but I have no idea how to get past the merge conflict; there's not actually any conflict to resolve that I can find. Any thoughts would be appreciated. EDIT: Just wanted to specify that I am working locally. I have a local branch for the trunk that references svn/trunk (the remote branch). All of my work was done on the local trunk: $ git branch maint-1.0.x master * trunk $ git branch -r svn/maintenance/my-project-1.0.0 svn/trunk Similarly, git log currently shows 10 commits on my local trunk since the last commit with a Svn ID. Hopefully that answers a few questions. Thanks again.
