• Is it possible to make the iPhone keyboard invisible / remove it without resigning first responder?

  - by Alex Gosselin

  I am looking for a way to show my own input view (a UITableView) to enter certain keywords in a UITextView faster than typing them, and also be able to type into this text view the normal way. My solution has a button that causes the keyboard to disappear, revealing the table view underneath it. Problem is I can't figure out how to make the keyboard go away without resigning first responder, and losing the cursor. Has anyone accomplished this before? Thanks for any help.

  Suppose I have a block of memory as such: void *block = malloc(sizeof(void *) + size); How do I set the first two bytes to a pointer or NULL while still being able to access the rest of the block of memory? For this reason, I do not want to simply assign 'block' to another pointer or NULL.

  - by Uri

  I am trying to identify the point in time where code completion (autocomplete/intellisense/whatever) was first introduced in IDEs and would appreciate any pointers. By code completion here I mean a feature within the editor that offers methods or suggestions based on the code that was already typed, and I am interested in programming language related completions (not word processor style completion).

• MySQL - Limit a left join to the first date-time that occurs?

  - by John M

  Simplified table structure (the tables can't be merged at this time): TableA: dts_received (datetime) dts_completed (datetime) task_a (varchar) TableB: dts_started (datetime) task_b (varchar) What I would like to do is determine how long a task took to complete. The join parameter would be something like ON task_a = task_b AND dts_completed < dts_started The issue is that there may be multiple date-times that occur after the dts_completed. How do I create a join that only returns the first tableB-datetime that occurs after the tableA-datetime?

• How do I delete the first line in a file?

  - by Soop

  I can't search for a particular string, since they're all very similar, but I'd like something simple to chop out the first 4 lines in a file. They're all variable length too. I've had a a think about perl, and it all seems harder than I thought, but I'd like to do it in Perl, AWK or a shell command if possible. Does anybody have a simple way of doing this?

• What pitfalls (if any) are there to learning C/C++ as a first language?

  - by thyrgle

  Hi, I first learned C++ then moved to C (I know kind of backwards) and then I found a thing called iTunes U and began watching programming classes to extend my knowledge and noticed that Stanford and MIT both did not teach C or C++ as an introduction to computer programming. Then I began to wonder why they didn't begin teaching C/C++ because I thought C/C++ was more efficient than Java (which Stanford taught) and Python (which MIT taught). Or maybe there is no particular reason?

• How to prevent regex from stopping at the first match of alternatives ?

  - by miket2e

  If I have the string hello world , how can I modify the regex world|wo|w so that it will match all of "world", "wo" and "w" rather than just the single first match of "world" that it comes to ? If this is not possible directly, is there a good workaround ? I'm using C# if it makes a difference: Regex testRegex = new Regex("world|wo|w"); MatchCollection theMatches = testRegex.Matches("hello world"); foreach (Match thisMatch in theMatches) { ... }
