• problem with iOS 4.2 when user press the list view item to go to UIwebview page and the navigation button disappears on the second visit

  - by seahorse

  My app is a Navigation based application. The main menu contains the list view items. if I clicks one of them, it goes to next view which in this case take me to UIwebview embedded web site. Everything is looking great. I can view the content of web page, the navigation control back button which takes to the main menu if I press it. However, I'm having issue when I try to go back to main menu if i visit that subview the second time. It loads the content of UIwebview web page, but the navigation button is gone and won't let me go back to main menu. This problem only appears on latest iOS 4.2 version. Otherwise it works great on 3.1 to 4.1. I would appreciate any hints or inputs. Note this seems not working for subview using UIWebview embedded web content. I don't have any issue with other subviews

• Image processing custom filter 7 by 7

  - by ladiesMan217

  Lets say I have a 7 by 7 neighborhood around a pixel that looks like this 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 and I wanna filter the above by replacing the pixel p by the average of those pixels whose value lie in the range -10<=p_value <=10. I am new to image processing and I think in this case p_value is 25 and around 25 that are many pixel values in that range but don't exactly know to construct a convolution filter out of it.

• Inline Zend Navigation links in view content saved to db

  - by takeshin

  I'm storing the page content in the database (both as markup and HTML code) and displaying this content in the view (let's say it's CMS or forum post). The this data have also some links to internal pages existing in sitemap (Zend_Navigation object). It's easy to insert the link in page body just by using <a> tag. But the contents of this inline links does not change when I update the sorce XML for Zend Navigation (url's, attributes, ACL permissions). How do you handle this case? Special markup for the link, converting the link using url view helper? Iterate Zend_Navigation object extracting specific link (one by one)?

• shouldAutorotateToInterfaceOrientation not working for detail view

  - by TheLearner

  I am using Xcode's SplitView template as the base for my project and I only want to accept Landscape mode. I have implemented the method in the RootViewController and DetailViewController: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { switch (interfaceOrientation) { case UIInterfaceOrientationLandscapeLeft: return YES; } return NO; } However what happens is the app loads with in Landscape mode with the tableview on the left but the detail view is black / blank. How do I get the detailview to load properly and do I need to implement this method is all view controllers or just the root one?

• my output parameters are always null when i use BeginExecuteNonQuery

  - by CharlesO

  I have a stored procedure that returns a varchar(160) as an output parameter of a stored procedure. Everything works fine when i use ExecuteNonQuery, i always get back the expected value. However, once i switch to use BeginExecuteNonQuery, i get a null value for the output. I am using connString + "Asynchronous Processing=true;" in both cases. Sadly the BeginExecuteNonQuery is about 1.5 times faster in my case...but i really need the output parameter. Thanks!

• I Need Help Fixing My Small Time Sheet Table - Relational DB - SQL Server

  - by user327387

  I have a TimeSheet table as: CREATE TABLE TimeSheet ( timeSheetID employeeID setDate timeIn outToLunch returnFromLunch timeOut ); Employee will set his/her time sheet daily, i want to ensure that he/she doesn't cheat. What should i do? Should i create a column that gets date/time of the system when insertion/update happens to the table and then compare the created date/time with the time employee's specified - If so in this case i will have to create date/time column for timeIn, outToLunch, returnFromLunch and timeOut. I don't know, what do you suggest? Note: i'm concerned about tracking these 4 columns timeIn, outToLunch, returnFromLunch and timeOut

• Checkbox - in Javascript

  - by smiley

  I am working on Edit screen where I am pulling out value from db to check if the checkbox is checked or not. If it is unchecked, it should deselect the checkbox and other controls of this checkbox. In my case the js works perfectly fine. That is if my previous screen has checkbox unchecked, edit screen disables all the values for this checkbox. But it still shows the checkbox is checked in UI(though it is actually checked). Something is wrong with my html code. Can someone please let me know where /how should i modify to display if my checkbox is unchecked? <%chkStatus=list.getCheckbox(); if (chkStatus == null) { chkStatus = ""; } %> <input id="chkbox" type="checkbox" name="chkbox" checked="<%=chkStatus%>" onchange="javascript:enableDisableTextBox();">

• How do I delete an object from an Entity Framework model without first loading it?

  - by Tomas Lycken

  I am quite sure I've seen the answer to this question somewhere, but as I couldn't find it with a couple of searches on SO or google, I ask it again anyway... In Entity Framework, the only way to delete a data object seems to be MyEntityModel ent = new MyEntityModel(); ent.DeleteObject(theObjectToDelete); ent.SaveChanges(); However, this approach requires the object to be loaded to, in this case, the Controller first, just to delete it. Is there a way to delete a business object referencing only for instance its ID? If there is a smarter way using Linq or Lambda expressions, that is fine too. The main objective, though, is to avoid loading data just to delete it.

• Contacts activity doesn't return data

  - by Mike

  In my app I simply open the list of activities and when a contact is clicked I attempt to retrieve the name of the contact selected and put it into a string. The app crashes in the onActivityResult() function. I do have the READ_CONTACTS permission set. /** * Opens the contacts activity */ public void openContacts() { Intent intent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI); startActivityForResult(intent, PICK_CONTACT); } @Override public void onActivityResult(int reqCode, int resultCode, Intent data) { super.onActivityResult(reqCode, resultCode, data); switch (reqCode) { case (PICK_CONTACT) : if (resultCode == Activity.RESULT_OK) { Uri contactData = data.getData(); Cursor c = managedQuery(contactData, null, null, null, null); //NullPointerException thrown here, line 102 if (c.moveToFirst()) { String name = c.getString(c.getColumnIndexOrThrow(People.NAME)); FRIEND_NAME = name; showConfirmDialog(name); } } break; } } The following logcat error logs are returned: Any help is appreciated. Thanks

• Stored Procedure - forcing execution order

  - by meepmeep

  I have a stored procedure that itself calls a list of other stored procedures in order: CREATE PROCEDURE [dbo].[prSuperProc] AS BEGIN EXEC [dbo].[prProc1] EXEC [dbo].[prProc2] EXEC [dbo].[prProc3] --etc END However, I sometimes have some strange results in my tables, generated by prProc2, which is dependent on the results generated by prProc1. If I manually execute prProc1, prProc2, prProc3 in order then everything is fine. It appears that when I run the top-level procedure, that Proc2 is being executed before Proc1 has completed and committed its results to the db. It doesn't always go wrong, but it seems to go wrong when Proc1 has a long execution time (in this case ~10s). How do I alter prSuperProc such that each procedure only executes once the preceding procedure has completed and committed? Transactions?

• Handling the distinction between undefined- and null-parameters in JavaScript

  - by Jakob

  I know very well that null and undefined are distinct in JavaScript. However, I can't seem to decide whether or not use that fact when my own functions are passed one of those as its argument. Or, expressed in a different way, should myFoo(undefined) return the same thing as myFoo(null) or is everything fine if it doesn't? Or, in yet another case, since myBar(1, 2, 3) is the same thing as myBar(1, 2, 3, undefined, undefined), should myBar(1, 2, 3, null, null) return the same thing as myBar(1, 2, 3)? I feel that there's potential for confusion in both cases and that a library should probably follow a convention when handling null/undefined. I'm not really asking for personal opinions (so please express those as comments rather than answers). I'm asking if anyone knows if there is a best practice that one should stick to when it comes to handling this distinction. References to external sources are very welcome!

• Is scala functional programming slower than traditional coding?

  - by Fred Haslam

  In one of my first attempts to create functional code, I ran into a performance issue. I started with a common task - multiply the elements of two arrays and sum up the results: var first:Array[Float] ... var second:Array[Float] ... var sum=0f; for(ix<-0 until first.length) sum += first(ix) * second(ix); Here is how I reformed the work: sum = first.zip(second).map{ case (a,b) => a*b }.reduceLeft(_+_) When I benchmarked the two approaches, the second method takes 40 times as long to complete! Why does the second method take so much longer? How can I reform the work to be both speed efficient and use functional programming style?

• What is the smallest amount of bits you can write twin-prime calculation?

  - by HH

  A succinct example in Python, its source. Explanation about the syntactic sugar here. s=p=1;exec"if s%p*s%~-~p:print`p`+','+`p+2`\ns*=p*p;p+=2\n"*999 The smallest amount of bits is defined by the smallest amount of 4pcs of things you can see with hexdump, it is not that precise measure but well-enough until an ambiguity. $ echo 's=p=1;exec"if s%p*s%~-~p:print`p`+','+`p+2`\ns*=p*p;p+=2\n"*999' > .test $ hexdump .test | wc 5 36 200 $ hexdump .test 0000000 3d73 3d70 3b31 7865 6365 6922 2066 2573 0000010 2a70 2573 2d7e 707e 703a 6972 746e 7060 0000020 2b60 2b2c 7060 322b 5c60 736e 3d2a 2a70 0000030 3b70 2b70 323d 6e5c 2a22 3939 0a39 000003e so in this case it is 31 because the initial parts are removed.

• How to prevent application thievery?

  - by Berdon Magnus

  Hey, I was wondering what the most effective way of preventing people from stealing my application (downloading a copy of the .apk online rather than buying it). I've spent a lot of time on one in particular (Droidbox) and won't be releasing Sync until I can guarantee that the people who are providing illegal copies of the pro version aren't able to. Anyone implemented this? I've tried checking my package signature verses an the signature of an unsigned copy but it appears to be the same - perhaps I'm doing something incorrectly here. I'm unsure whether people actually distribute the signed .apk in which case I don't think signature validation would work to begin with...

• Object initialization sequence in Objective-C

  - by Alex

  Hello everyone. The Cocoa framework has a convention to always call self = [super init] in the init method of an inherited class, because [super init] may return a new instance. What will happen if I do this? @interface MyClass : NSObject /* or any other class */ { int ivar_; } @end @implementation MyClass - (id)init { ivar_ = 12345; if ((self = [super init])) { NSLog(@"ivar_'s value is %d", ivar_); } return self; } @end In the case when [super init] returns a new instance, what will I see in the console? ivar_'s value is 0? I can't think of a way to check this myself, because I don't know which class may return a new instance from its init method. Also, can't seem to find explicit clarification for this scenario in the docs. Could anyone help me out? Thanks!

Can anybody please suggest wheather what will be better to use push notifications or thread with timer? Thanx in advance.

• How do I profile memory usage in my project

  - by Gacek

  Are there any good, free tools to profile memory usage in C# ? Details: I have a visualization project that uses quite large collections. I would like to check which parts of this project - on the data-processing side, or on the visualization side - use most of the memory, so I could optimize it. I know that when it comes to computing size of the collection the case is quite simple and I can do it on my own. But there are also certain elements for which I cannot estimate the memory usage so easily. The memory usage is quite big, for example processing a file of size 35 MB my program uses a little bit more than 250 MB of RAM.

• SSRS and cached reports

  - by Tabloo Quijico

  Hi, I'm opening an SSRS2008 report using the http://server/reportserver/... syntax, outputting directly a PDF copy. This report has several parameters. The problem is that, despite making changes to the report, and clearing the browser's temporary files cache.. if I request the same report (i.e. same parameters) - the old report is returned. In the report execution properties, I have "Always run this report with the most recent data" and "Do not cache temporary copies of this report" selected. It's not just a case of caching data, but the entire report (including formatting, e.g. I deleted a page from the report yet it was still being shown...) and as I haven't specifically chosen to perform any caching I'm a little concerned and clearly don't fully understand what's going on! Any tips?

• Can you get the previous value of a variable in Java?

  - by The Special One

  Say way have a variable (let's say String Str) and the value of Str starts of as " " then as some code is running it is set to "test" then somewhere else in the code it is changed again to say "tester". Now in the program I want to find out what the previous value of Str was. Is this possible in Java? So I am saying that the variable gets changed twice, and you want to find out what Str was before it got changed for the second time. So in the example above the latest value of Str would be "tester" but I wanted to find out what Str was before this (assuming you had no idea what it was before it was changed to tester) in this case I would want to be able to find out that Str was "test". Is it at all possible to do this in Java?

• Fallback to another exiting MIME type when the required is missing in Rails

  - by fifigyuri

  I want to extend the exiting supported HTML type of my site by support for iPhone. For this I registered a new MIME type. I created a layout for iphone and also converted some of the html views to iphone version. However, I did not convert all of the html.erb-s. I do not see the reason to convert all views, some of them should not change, some partials simply just remain the same. I guess there should be a solution for this case. I tried to search for ways how to fallback to an existing format, but did not find any answer. Does a way to define fallback for MIME types in Rails exist? How does it work? If it doesn't exist and thus I wanted to solve the issue not the right way, what could simply solve the task of extending an existing site by another format? Thanks for your suggestions.

• When (and why) is {} undefined in a JavaScript console?

  - by JS_Riddler

  In the console of both FF and Chrome, {} is considered undefined until explicitly evaluated: {}; // undefined ({}); // ? Object Actually, it's a bit less defined than undefined -- it's apparently bad syntax: {} === undefined; // SyntaxError: Unexpected token === {}.constructor; // SyntaxError: Unexpected token . But not if it's on the other side, in which case it's fine: "[object Object]" == {}.toString(); // true Or if it's not the first expression: undefined + undefined; // NaN {} + undefined; // NaN undefined + {}; // "undefined[object Object]" What gives?

• Solr 'text' fields not accepting wild-cards

  - by MarcoPolo

  Hi, I am trying to search on a field declared as 'text' using the wildcard '*' but am getting mixed results. Basically, it seems to me that it's stripping off the '*' character and isn't handling numbers or spaces well. I'm using the 'text' field type for case insensitive fields but after running an analysis, am starting to think itmight be the wrong type to use as it runs a lot more filters when compared with the string field. Basically all I want is a field type that can index or search on lowercase only with spaces stripped out (and works with wildcards). Is such a type available? Thanks MARCO

• What to do when using Contract.Assert(true) and the method must return something?

  - by devoured elysium

  I have a bit of code with the following logic: //pseudo-code foreach (element in elementList) { if (element is whatever) return element; } } In theory, there is always one element that is whatever, so this method should pose no problems. In any case, I've put an assertion on the end of the method just to be sure: //pseudo-code foreach (element in elementList) { if (element is whatever) return element; } } Contract.Assert(true, "Invalid state!"); The problem is that as this method has to return something, and the compiler doesn't understand that the assertion will break the program execution. Before using Contracts, in these kind of situations, I used to throw an Exception, which solved the problem. How would you handle this with Contract.Assert()? Returning null or default(element_type) after the Contract.Assert() call knowing it will never be called and shutting up the compiler? Or is there any other more elegant way of doing this? Thanks

• for loop vs while loop

  - by Atul

  We can use for loop and while loop for same purpose. in what means they effect our code if I use for instead of while? same question arises between if-else and switch-case? how to decide what to use? for example which one you would prefer? This code: int main() { int n; cin>>n; for(int i=0;i<n;i++) { do_something(); } return 0; } Or this code: int main() { int n,i=0; cin>>n; while(i<n) { do_something(); i++; } return 0; } if using for or while loop does not effect the code by any means then may I know What was the need to make 2 solution for same problem?
