WebSQL Databases between two different pages?

- by Srikanth Rayabhagi

Is there any particular way in which we can access the Web SQL Database of one page, by other page. To make it more clear, suppose a.com creates the database DB and store some info. Now b.com comes and want to access the same database DB. Is there a way? Or are there any alternatives to do this? I tried to implement in HTML5 and Javascript but the databases as well as the localStorages are confining only to particular pages, I want this to be cross the pages.

Using Predicate of a class to Search Generic list - Faster than looping?

- by Srikanth

Lets say we have a generic list of Class1, typically having ~100 objects for a given session. I would like to see if the list has a particular object. ASP.NET 2.0 allows me to do this: Dim objResult as Class1 = objList.Find(objSearch) How does this approach rate when compared to a traditional For loop, looking at a performance perspective? How would this vary with increase or decrease in length of the list?

I have written my code in following way in cocos2d. id actionTo = [CCFadeOut actionWithDuration:4.0f]; id actionTo0 = [CCSequence actionWithDuration:2.0f]; if (m < enemyNumber) id actionTo1 = [CCCallFunc actionWithTarget:self selector:@selector(goToNextScene)]; else id actionTo1 = [CCCallFunc actionWithTarget:self selector:@selector(goToEndScene)]; id actionSeq = [CCSequence actions:actionTo, actionTo0, actionTo1, nil]; [targetE runAction: [CCSequence actions:actionSeq, nil]]; error: expected expression before 'id' I am getting the above error. Should not we use (id) in if condition ? I want to get called two selectors by using the if- else condition. How can I make it ? Thank You.

X server not starting up after new kernel compilation

- by tech_learner

I have compiled the Kernel on my 64-bit Debian XPS Studio 1340 Dell system. srikanth@debian:~ - 05:40:52 PM - $ uname -a Linux debian 2.6.32-5-amd64 #1 SMP Thu Mar 22 17:26:33 UTC 2012 x86_64 GNU/Linux Kernel version that I have used and compiled from kernel.org is 2.6.35.13 I have nvidia installed on old kernel. I got the old config and I used the same config to compile the new kernel. Everything went well and I got two debian packages ( image and headers ) which I have installed on my system. When I select the new kernel on the boot menu and I go into it, the X server is not starting up possibly because I have to "rebuild" ( not sure how to do that ) according to this link: http://www.linuxquestions.org/questions/slackware-14/x-server-not-starting-after-kernel-compilation-605265/ Can you suggest how to do the rebuild on nvidia module so that I can start x ( without seeing any blank screen or error saying nvidia module is missing ) ? PS: The link that I have used to compile the kernel is https://help.ubuntu.com/community/Kernel/Compile#Alternate_Build_Method:_The_Old-Fashioned_Debian_Way

ios UITableView reloadData don't increase content height

- by Zoltan Varadi

I'm facing a strange error in my iOS app and haven't been able to figure out the reason why. In my UITableView i can add new cells, so i refresh the array that is the datasource and call reloadData. Everything works without error. The numberOfRowsInSection is called again, and it's value is one more than it's previous value was. The new cell even gets inserted at the bottom of the tableview, but i cant scroll down to it. I only know that it's there because the tableview bounces and i can see it. I'm guessing the tableview's content height is not getting increased for some reason, but i have no idea why. I'm using iOS 6 btw. Any help is very much appreciated! Thanks, Zoli EDIT, answers for Srikanth's questions: How is data getting added. There's an NSArray containing objects of a specific type. The array.count is the number of the number of cells. This NSArray gets its values from a database query. When you say, you are refreshing the array, what do you mean. By refreshing the array i mean i execute a new query in the database and put the results of this query into an NSArray. this will be the tableview's datasource array. Like this: dataSourceArray = [dbManager executeQuery]; [tableView reloadData]; Are you adding the data within the same view controller Yes. Can you show some code as to what you are doing See above. Is the table view at the root of the view controllers view or is it within another view The tableview is the main view's first child. Can you try adding data to the array at the beginning, so that you can view the cell being added at the top. I don't understand what you mean.
