Alternative for didSelectRowAtIndexPath when UITableViewCells are UIResponders?

The cells in my tableview are horizontal UIScrollViews, which I assume is the reason didSelectRowAtIndexPath is not being called. I have my resignFirstResponder call in that method. Does anyone have an easy way for me to fix this? Is there an alternative to didSelectRowAtIndexPath? Or is there a way to get that method to fire? Thanks!Read the article

Possible to use Bindings only for the SourceChanged event?
- by Schneider
Basically I want to use the WPF Binding framework to "observe" a property in the data context, and when that value changes to call an event handler. I do not actually want to bind it to any target. Sounds simple but from what I can see Binding is too coupled (to the visual tree and various other bits) to be able to use it flexibly. Any thoughts?Read the article

Usage of initialize() vs. setup() in Mootools
- by RyOnLife
Mootools classes have an initialize() method that's called when a new object is instantiated. It seems that setup() is a commonly used method as well. Most classes I've observed call this.setup() from initialize() and nowhere else, which has left me wondering: What's the purpose of setup()? Why not just put the setup() code in initialize()? When does it make sense to use a setup() method?Read the article

ASP.NET MVC model state as text

Is there an easy way to get a summary string of the errors that have been added to a controller's modelstate? I'm looking to return this in an Ajax method and want the validation errors etc to be returned to the client (i.e. the view does not exist for this method call). Or do I have to loop through the modelstate and look at each object and extract the error text manually?Read the article

when to use "willChangeValueForKey" and "didChangeValueForKey"?
- by Frost Li
I saw these lines in a demo project, but I couldn't understand why it did that. [self willChangeValueForKey:@"names"]; [self didChangeValueForKey:@"names"]; It called didChangeValueForKey immediately after willChangeeValueForKey. Does it make any sense? Furthermore, when should be the right time to call this two methods? Thanks a lot!! :)Read the article

Calling Windows commands (e.g. del) from a GNU makefile
- by Tom
It does not appear to be possible to call Windows system commands (e.g. del, move, etc) using GNU Make. When the following rule is run, an error is reported del: command not found: clean: del *.o This is presumably because there is no such execuatable as "del". I've also tried running it as an option to cmd but with this only seems to open a new prompt: clean: cmd /C del *.o I'm using GNU Make 3.79.1 that is bundled as part of MSys.Read the article
