3,664,738 | 0 | <p>This is an interesting question. For sure I would say start with UIScrollView, and set the content size bigger than the screen size, exactly how big is up to you.</p> <p>Next you'll want to make some kind of implementation that efficiently figures out what cells are on screen. If I were you I would do something similar to how UITableView is done, i.e. make a custom object that keeps track of what indexes should be on screen based on the offset of the scroll view.</p> <p>Next you'll need this custom object to either directly or indirectly get the visible cells to display themselves on screen when they are visible, and remove them from the superview when they aren't. I'd also recommend reusing the views that are offscreen.</p> <p>This is a moderately challenging thing you are trying to make, so be sure you are very organized and don't be scared to make a few new custom object to perform specific tasks. </p> <p>Sample interface file:</p> <pre><code> @protocol doubleTableViewDelegate -(NSInteger)heightForRow:(NSInteger)row; -(NSInteger)widthForCol:(NSInteger)col; -(NSInteger)numberOfRows:(NSInteger)rows; -(NSInteger)numberOfCols:(NSInteger)cols; -(UIView *)cellForRow:(NSInteger)row col:(NSInteger)col; //get the custom table view to store and dequeue these, i.e. store them in an NSSet when they go offscreen, and give them back when a certain function is called. //There's probably a few functions missing here still. @end @interface doubleTableView: UIScrollView { id<doubleTableViewDelegate> infoDelegate; } //your functions to show and remove cells as needed @end </code></pre> <p>You'll need to work out the rest, but keep updating this page and I'll try to help out.

16,410,844 | 0 | Multiple matches for syntax highlighting in VIM <p>I'm writing a syntax file to match a log format (basically column based; think syslog for a similar example), and I'm trying to set up a type of inheritance for columns.</p> <p>I have two main goals with this.</p> <p>First, I want to say that column 3 is the "component" field (let's say it's marked by a header; it could also be at a fixed position) and set the background to, say, Grey. I then want to say that component "foo" gets a foreground color of Red, and component "bar" gets a foreground color of Green, but they should inherit the background color of the "component" column. In this case, the field should really have two syntax matches; this also makes it easy to conceal the entire column (a la <a href="http://stackoverflow.com/questions/3853631/toggling-the-concealed-attribute-for-a-syntax-highlight-in-vim">Toggling the concealed attribute for a syntax highlight in VIM</a>)</p> <p>Second, there's a field for levels; I want to set the background of the entire line for a critical level message to Red, but the foreground should be continue to be set via the normal highlighting (component, source, etc; I left off most of the other requirements).</p> <p>From what I can see in the vim documentation, this doesn't seem possible. Am I missing something? Alternatively, can anyone suggest a good workaround?</p> <p>Thanks</p> |

For more advanced ussages you might want to check out jquery at <a href="http://jquery.com/" rel="nofollow noreferrer">http://jquery.com/</a> which goes together great with asp.net MVC. There are also allot more information, samples and libraries in the public domain for jquery then for asp.net ajax.

In this case, you would something like:</p> <pre><code>having (case when count(nationality = 'Mexican' then children end) > 3 then 'true' when count(nationality = 'American' then children end) = 2 then 'true' when count(nationality = 'Japanese' then children end) = 1 then 'true' end) = 'true' </code></pre> <p>However, even this seems strange. Why are you counting "children". What are you grouping on?

25,395,651 | 0 | Storing PBKDF2 Settings Alongside Password <p>I'm experimenting with PBKDF2 for my passwords right now, and it dawned on me that if I were to ever upgrade to a faster machine in the future, I would want to increase the number of PBKDF2 iterations. However, this would invalidate all the current passwords that I have stored. One idea I've seen was to store the PBKDF2 settings along with the password (similar to how you store the salt) such as the iteration count and the PRF used (SHA-256, SHA-512) at the time of the hash creation. It sounds like a good idea in terms of backwards compatibility, but I wanted to know if there are any drawbacks to doing this. Any insight into this would be appreciated.</p> |

30,258,295 | 0 | Is my HTTP protocol design correctly implemented in the coding? <p>It's my very simple client-server application. Client sends some commands to the server and server gives back the output to the client. However, my special concern is about the <code>GET</code> command sent to the server. The client request <code>GET filename</code> to download a named file. That file ultimately gets downloaded into the client directory with the HTTP response headers, as I have designed my protocol.</p> <p>Now I am afraid if my coding follows the protocol accurately.

40,288,900 | 0 | 2 flexbox columns side by side, both with fluid height, with one never exceeding the height of the other <p>I'm using flexbox to show two <code><div></code>s side by side. One has a video and the other has text. Neither <code><div></code> has a fixed height. I want the text div to never be taller than the video div.
